                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1
    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, July 1, 1997), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

OBSOLETE PROVISIONS

    Provisions that become obsolete before the revision date stated on 
the cover of each volume are not carried. Code users may find the text 
of provisions in effect on a given date in the past by using the 
appropriate numerical list of sections affected. For the period before 
January 1, 1986, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, or 1973-1985, published in seven separate volumes. For 
the period beginning January 1, 1986, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    Properly approved incorporations by reference in this volume are 
listed in the Finding Aids at the end of this volume.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed in 
the Finding Aids of this volume as an approved incorporation by 
reference, please contact the agency that issued the regulation 
containing that incorporation. If, after contacting the agency, you find 
the material is not available, please notify the Director of the Federal 
Register, National Archives and Records Administration, Washington DC 
20408, or call (202) 523-4534.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Statutory 
Authorities and Agency Rules (Table I), and Acts Requiring Publication 
in the Federal Register (Table II). A list of CFR titles, chapters, and 
parts and an alphabetical list of agencies publishing in the CFR are 
also included in this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.

[[Page vii]]

    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

Sec. 260.10  Definitions.

    When used in parts 260 through 266, 268, and 270 through 273 of this 
chapter, the following terms have the meanings given below:
    When used in parts 260 through 266 and 268 of this chapter, the 
following terms have the meanings given below:
    Above ground tank means a device meeting the definition of ``tank'' 
in Sec. 260.10 and that is situated in such a way that the entire 
surface area of the tank is completely above the plane of the adjacent 
surrounding surface and the entire surface area of the tank (including 
the tank bottom) is able to be visually inspected.
    Act or RCRA means the Solid Waste Disposal Act, as amended by the 
Resource Conservation and Recovery Act of 1976, as amended, 42 U.S.C. 
section 6901 et seq.
    Active life of a facility means the period from the initial receipt 
of hazardous waste at the facility until the Regional Administrator 
receives certification of final closure.
    Active portion means that portion of a facility where treatment, 
storage, or disposal operations are being or have been conducted after 
the effective date of part 261 of this chapter and which is not a closed 
portion. (See also ``closed portion'' and ``inactive portion''.)
    Administrator means the Administrator of the Environmental 
Protection Agency, or his designee.
    Ancillary equipment means any device including, but not limited to, 
such devices as piping, fittings, flanges, valves, and pumps, that is 
used to distribute, meter, or control the flow of hazardous waste from 
its point of generation to a storage or treatment tank(s), between 
hazardous waste storage and treatment tanks to a point of disposal 
onsite, or to a point of shipment for disposal off-site.
    Aquifer means a geologic formation, group of formations, or part of 
a formation capable of yielding a significant amount of ground water to 
wells or springs.
    Authorized representative means the person responsible for the 
overall operation of a facility or an operational unit (i.e., part of a 
facility), e.g., the plant manager, superintendent or person of 
equivalent responsibility.
    Battery means a device consisting of one or more electrically 
connected electrochemical cells which is designed to receive, store, and 
deliver electric energy. An electrochemical cell is a system consisting 
of an anode, cathode, and an electrolyte, plus such connections 
(electrical and mechanical) as may be needed to allow the cell to 
deliver or receive electrical energy. The term battery also includes an 
intact,

[[Page 7]]

unbroken battery from which the electrolyte has been removed.
    Boiler means an enclosed device using controlled flame combustion 
and having the following characteristics:
    (1)(i) The unit must have physical provisions for recovering and 
exporting thermal energy in the form of steam, heated fluids, or heated 
gases; and
    (ii) The unit's combustion chamber and primary energy recovery 
sections(s) must be of integral design. To be of integral design, the 
combustion chamber and the primary energy recovery section(s) (such as 
waterwalls and superheaters) must be physically formed into one 
manufactured or assembled unit. A unit in which the combustion chamber 
and the primary energy recovery section(s) are joined only by ducts or 
connections carrying flue gas is not integrally designed; however, 
secondary energy recovery equipment (such as economizers or air 
preheaters) need not be physically formed into the same unit as the 
combustion chamber and the primary energy recovery section. The 
following units are not precluded from being boilers solely because they 
are not of integral design: process heaters (units that transfer energy 
directly to a process stream), and fluidized bed combustion units; and
    (iii) While in operation, the unit must maintain a thermal energy 
recovery efficiency of at least 60 percent, calculated in terms of the 
recovered energy compared with the thermal value of the fuel; and
    (iv) The unit must export and utilize at least 75 percent of the 
recovered energy, calculated on an annual basis. In this calculation, no 
credit shall be given for recovered heat used internally in the same 
unit. (Examples of internal use are the preheating of fuel or combustion

[45 FR 33073, May 19, 1980, as amended at 49 FR 47391, Dec. 4, 1984]



Sec. 260.22  Petitions to amend part 261 to exclude a waste produced at a particular facility.

    (a) Any person seeking to exclude a waste at a particular generating 
facility from the lists in subpart D of part 261 may petition for a 
regulatory amendment under this section and Sec. 260.20. To be 
successful:
    (1) The petitioner must demonstrate to the satisfaction of the 
Administrator that the waste produced by a particular generating 
facility does not meet any of the criteria under which the waste was 
listed as a hazardous or an actutely hazardous waste; and
    (2) Based on a complete application, the Administrator must 
determine, where he has a reasonable basis to believe that factors 
(including additional constituents) other than those for which the waste 
was listed could cause the waste to be a hazardous waste, that such 
factors do not warrant retaining the waste as a hazardous waste. A waste 
which is so excluded, however, still may be a hazardous waste by 
operation of subpart C of part 261.
    (b) The procedures in this Section and Sec. 260.20 may also be used 
to petition the Administrator for a regulatory amendment to exclude from 
Sec. 261.3(a)(2)(ii) or (c), a waste which is described in these 
Sections and is either a waste listed in subpart D, or is derived from a 
waste listed in subpart D. This exclusion may only be issued for a 
particular generating, storage, treatment, or disposal facility. The 
petitioner must make the same demonstration as required by paragraph (a) 
of this section. Where the waste is a mixture of solid waste and one or 
more listed hazardous wastes or is derived from one or more hazardous 
wastes, his demonstration must be made with respect to the waste mixture 
as a whole; analyses must be conducted for not only those constituents 
for which the listed waste contained in the mixture was listed as 
hazardous, but also for factors (including additional constituents) that 
could cause the waste mixture to be a hazardous waste. A waste which is 
so excluded may still be a hazardous waste by operation of subpart C of 
part 261.
    (c) If the waste is listed with codes ``I'', ``C'', ``R'', or ``E'', 
in subpart D,
    (1) The petitioner must show that the waste does not exhibit the 
relevant characteristic for which the waste was listed as defined in 
Sec. 261.21, Sec. 261.22, Sec. 261.23, or Sec. 261.24 using any 
applicable methods prescribed therein. The petitioner also must show 
that the waste does not exhibit any of the other characteristics defined 
in Sec. 261.21, Sec. 261.22, Sec. 261.23, or Sec. 261.24 using any 
applicable methods prescribed therein;
    (2) Based on a complete application, the Administrator must 
determine, where he has a reasonable basis to believe that factors 
(including additional constituents) other than those for which the waste 
was listed could cause the waste to be hazardous waste, that such 
factors do not warrant retaining the waste as a hazardous waste. A waste 
which is so excluded, however, still may be a hazardous waste by 
operation of subpart C of part 261.
    (d) If the waste is listed with code ``T'' in subpart D,
    (1) The petitioner must demonstrate that the waste:
    (i) Does not contain the constituent or constituents (as defined in 
Appendix VII of part 261 of this chapter) that caused the Administrator 
to list the waste, using the appropriate test methods prescribed in 
``Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,'' 
EPA Publication SW-846, as incorporated by reference in Sec. 260.11; or
    (ii) Although containing one or more of the hazrdous constituents 
(as defined in appendix VII of part 261) that caused the Administrator 
to list the waste, does not meet the criterion of Sec. 261.11(a)(3) when 
considering the factors used by the Administrator in

[[Page 20]]

Sec. 261.11(a)(3) (i) through (xi) under which the waste was listed as 
hazardous; and
    (2) Based on a complete application, the Administrator must 
determine, where he has a reasonable basis to believe that factors 
(including additional constituents) other than those for which the waste 
was listed could cause the waste to be a hazardous waste, that such 
factors do not warrant retaining the waste as a hazardous waste; and
    (3) The petitioner must demonstrate that the waste does not exhibit 
any of the characteristics defined in Sec. 261.21, Sec. 261.22, 
Sec. 261.23, and Sec. 261.24 using any applicable methods prescribed 
therein;
    (4) A waste which is so excluded, however, still may be a hazardous 
waste by operation of subpart C of part 261.
    (e) If the waste is listed with the code ``H'' in subpart D,
    (1) The petitioner must demonstrate that the waste does not meet the 
criterion of Sec. 261.11(a)(2); and
    (2) Based on a complete application, the Administrator must 
determine, where he has a reasonable basis to believe that additional 
factors (including additional constituents) other than those for which 
the waste was listed could cause the waste to be a hazardous waste, that 
such factors do not warrant retaining the waste as a hazardous waste; 
and
    (3) The petitioner must demonstrate that the waste does not exhibit 
any of the characteristics defined in Sec. 261.21, Sec. 261.22, 
Sec. 261.23, and Sec. 261.24 using any applicable methods prescribed 
therein;
    (4) A waste which is so excluded, however, still may be a hazardous 
waste by operation of subpart C of part 261.
     (f) [Reserved for listing radioactive wastes.]
    (g) [Reserved for listing infectious wastes.]
    (h) Demonstration samples must consist of enough representative 
samples, but in no case less than four samples, taken over a period of 
time sufficient to represent the variability or the uniformity of the 
waste.
    (i) Each petition must include, in addition to the information 
required by Sec. 260.20(b):
    (1) The name and address of the laboratory facility performing the 
sampling or tests of the waste;
    (2) The names and qualifications of the persons sampling and testing 
the waste;
    (3) The dates of sampling and testing;
    (4) The location of the generating facility;
    (5) A description of the manufacturing processes or other operations 
and feed materials producing the waste and an assessment of whether such 
processes, operations, or feed materials can or might produce a waste 
that is not covered by the demonstration;
    (6) A description of the waste and an estimate of the average and 
maximum monthly and annual quantities of waste covered by the 
demonstration;
    (7) Pertinent data on and discussion of the factors delineated in 
the respective criterion for listing a hazardous waste, where the 
demonstration is based on the factors in Sec. 261.11(a)(3);
    (8) A description of the methodologies and equipment used to obtain 
the representative samples;
    (9) A description of the sample handling and preparation techniques, 
including techniques used for extraction, containerization and 
preservation of the samples;
    (10) A description of the tests performed (including results);
    (11) The names and model numbers of the instruments used in 
performing the tests; and
    (12) The following statement signed by the generator of the waste or 
his authorized representative:

    I certify under penalty of law that I have personally examined and 
am familiar with the information submitted in this demonstration and all 
attached documents, and that, based on my inquiry of those individuals 
immediately responsible for obtaining the information, I believe that 
the submitted information is true, accurate, and complete. I am aware 
that there are significant penalties for submitting false information, 
including the possibility of fine and imprisonment.

    (j) After receiving a petition for an exclusion, the Administrator 
may request any additional information which he may reasonably require 
to evaluate the petition.
    (k) An exclusion will only apply to the waste generated at the 
individual

[[Page 21]]

facility covered by the demonstration and will not apply to waste from 
any other facility.
    (l) The Administrator may exclude only part of the waste for which 
the demonstration is submitted where he has reason to believe that 
variability of the waste justifies a partial exclusion.

    (a) Materials that are accumulated speculatively without sufficient 
amounts being recycled (as defined in Sec. 261.1(c)(8) of this chapter);
    (b) Materials that are reclaimed and then reused within the original 
production process in which they were generated; and
    (c) Materials that have been reclaimed but must be reclaimed further 
before the materials are completely recovered.

Sec. 260.31  Standards and criteria for variances from classification as a solid waste.

    (a) The Administrator may grant requests for a variance from 
classifying as a solid waste those materials that are accumulated 
speculatively without sufficient amounts being recycled if the applicant 
demonstrates that sufficient amounts of the material will be recycled or 
transferred for recycling in the following year. If a variance is 
granted, it is valid only for the following year, but can be renewed, on 
an annual basis, by filing a new application. The Administrator's 
decision will be based on the following criteria:
    (1) The manner in which the material is expected to be recycled, 
when the material is expected to be recycled, and whether this expected 
disposition is likely to occur (for example, because of past practice, 
market factors, the nature of the material, or contractual arrangements 
for recycling);
    (2) The reason that the applicant has accumulated the material for 
one or more years without recycling 75 percent of the volume accumulated 
at the beginning of the year;
    (3) The quantity of material already accumulated and the quantity 
expected to be generated and accumulated before the material is 
recycled;

[[Page 22]]

    (4) The extent to which the material is handled to minimize loss;
    (5) Other relevant factors.
    (b) The Administrator may grant requests for a variance from 
classifying as a solid waste those materials that are reclaimed and then 
reused as feedstock within the original production process in which the 
materials were generated if the reclamation operation is an essential 
part of the production process. This determination will be based on the 
following criteria:
    (1) How economically viable the production process would be if it 
were to use virgin materials, rather than reclaimed materials;
    (2) The prevalence of the practice on an industry-wide basis;
    (3) The extent to which the material is handled before reclamation 
to minimize loss;
    (4) The time periods between generating the material and its 
reclamation, and between reclamation and return to the original primary 
production process;
    (5) The location of the reclamation operation in relation to the 
production process;
    (6) Whether the reclaimed material is used for the purpose for which 
it was originally produced when it is returned to the original process, 
and whether it is returned to the process in substantially its original 
form;
    (7) Whether the person who generates the material also reclaims it;
    (8) Other relevant factors.
    (c) The Regional Administrator may grant requests for a variance 
from classifying as a solid waste those materials that have been 
reclaimed but must be reclaimed further before recovery is completed if, 
after initial reclamation, the resulting material is commodity-like 
(even though it is not yet a commercial product, and has to be reclaimed 
further). This determination will be based on the following factors:
    (1) The degree of processing the material has undergone and the 
degree of further processing that is required;
    (2) The value of the material after it has been reclaimed;
    (3) The degree to which the reclaimed material is like an analogous 
raw material;
    (4) The extent to which an end market for the reclaimed material is 
guaranteed;
    (5) The extent to which the reclaimed material is handled to 
minimize loss;
    (6) Other relevant factors.

Sec. 260.32  Variance to be classified as a boiler.

    In accordance with the standards and criteria in Sec. 260.10 
(definition of ``boiler''), and the procedures in Sec. 260.33, the 
Administrator may determine on a case-by-case basis that certain 
enclosed devices using controlled flame combustion are boilers, even 
though they do not otherwise meet the definition of boiler contained in 
Sec. 260.10, after considering the following criteria:
    (a) The extent to which the unit has provisions for recovering and 
exporting thermal energy in the form of steam, heated fluids, or heated 
gases; and
    (b) The extent to which the combustion chamber and energy recovery 
equipment are of integral design; and
    (c) The efficiency of energy recovery, calculated in terms of the 
recovered energy compared with the thermal value of the fuel; and
    (d) The extent to which exported energy is utilized; and
    (e) The extent to which the device is in common and customary use as 
a ``boiler'' functioning primarily to produce steam, heated fluids, or 
heated gases; and
    (f) Other factors, as appropriate.

Sec. 260.33  Procedures for variances from classification as a solid waste or to be classified as a boiler.

    The Administrator will use the following procedures in evaluating 
applications for variances from classification as a solid waste or 
applications to classify particular enclosed controlled flame combustion 
devices as boilers:
    (a) The applicant must apply to the Administrator for the variance. 
The application must address the relevant criteria contained in 
Sec. 260.31 or Sec. 260.32.
    (b) The Administrator will evaluate the application and issue a 
draft notice

[[Page 23]]

tentatively granting or denying the application. Notification of this 
tentative decision will be provided by newspaper advertisement or radio 
broadcast in the locality where the recycler is located. The 
Administrator will accept comment on the tentative decision for 30 days, 
and may also hold a public hearing upon request or at his discretion. 
The Administrator will issue a final decision after receipt of comments 
and after the hearing (if any).

[59 FR 48041, Sept. 19, 1994]



Sec. 260.40  Additional regulation of certain hazardous waste recycling activities on a case-by-case basis.

    (a) The Regional Administrator may decide on a case-by-case basis 
that persons accumulating or storing the recyclable materials described 
in Sec. 261.6(a)(2)(iv) of this chapter should be regulated under 
Sec. 261.6 (b) and (c) of this chapter. The basis for this decision is 
that the materials are being accumulated or stored in a manner that does 
not protect human health and the environment because the materials or 
their toxic constituents have not been adequately contained, or because 
the materials being accumulated or stored together are incompatible. In 
making this decision, the Regional Administrator will consider the 
following factors:
    (1) The types of materials accumulated or stored and the amounts 
accumulated or stored;
    (2) The method of accumulation or storage;
    (3) The length of time the materials have been accumulated or stored 
before being reclaimed;
    (4) Whether any contaminants are being released into the 
environment, or are likely to be so released; and
    (5) Other relevant factors.
    (b) [Reserved]

The procedures for this decision are set forth in Sec. 260.41 of this 
chapter.

[50 FR 662, Jan. 4, 1985]



Sec. 260.41  Procedures for case-by-case regulation of hazardous waste recycling activities.

    The Regional Administrator will use the following procedures when 
determining whether to regulate hazardous waste recycling activities 
described in Sec. 261.6(a)(2)(iv) under the provisions of Sec. 261.6 (b) 
and (c), rather than under the provisions of subpart F of part 266 of 
this chapter.
    (a) If a generator is accumulating the waste, the Regional 
Administrator will issue a notice setting forth the factual basis for 
the decision and stating that the person must comply with the applicable 
requirements of subparts A, C, D, and E of part 262 of this chapter. The 
notice will become final within 30 days, unless the person served 
requests a public hearing to challenge the decision. Upon receiving such 
a request, the Regional Administrator will hold a public hearing. The 
Regional Administrator will provide notice of the hearing to the public 
and allow public participation at the hearing. The Regional 
Administrator will issue a final order after the hearing stating whether 
or not compliance with part 262 is required. The order becomes effective 
30 days after service of the decision unless the Regional Administrator 
specifies a later date or unless review by the Administrator is 
requested. The order may be appealed to the Administrator by any person 
who participated in the public hearing. The Administrator may choose to 
grant or to deny the appeal. Final Agency action occurs when a final 
order is issued and Agency review procedures are exhausted.
    (b) If the person is accumulating the recyclable material as a 
storage facility, the notice will state that the person must obtain a 
permit in accordance with all applicable provisions of parts 270 and 124 
of this chapter. The owner or operator of the facility must apply for a 
permit within no less than 60 days and no more than six months of 
notice, as specified in the notice. If the owner or operator of the 
facility wishes to challenge the Regional Administrator's decision, he 
may do so in his permit application, in a public hearing held on the 
draft permit, or in comments filed on the draft permit or on the notice 
of intent to deny the permit. The fact sheet accompanying the permit 
will specify the reasons for the Agency's determination. The question of 
whether the Regional Administrator's decision

[[Page 24]]

was proper will remain open for consideration during the public comment 
period discussed under Sec. 124.11 of this chapter and in any subsequent 
hearing.

       Appendix I to Part 260--Overview of Subtitle C Regulations

    The Agency believes that there are many people who suspect, but are 
not sure, that their activities are subject to control under the RCRA 
Subtitle C rules. This appendix is written for these people. It is 
designed to help those who are unfamiliar with the hazardous waste 
control program to determine with which, if any, of the regulations they 
should comply.

                        Definition of Solid Waste

    The first question which such a person should ask himself is: ``Is 
the material I handle a solid waste?'' If the answer to this question is 
``No'', then the material is not subject to control under RCRA and, 
therefore, the person need not worry about whether he should comply with 
the Subtitle C rules.
    Section 261.2 of this chapter provides a definition of ``solid 
waste'' which expands the statutory definition of that term given in 
section 1004(27) of RCRA. This definition is diagrammed in Figure 1 
below.
    Figure 1 explains that all materials are either: (1) Garbage refuse, 
or sludge; (2) solid, liquid, semi-solid or contained gaseous material; 
or (3) something else. No materials in the third category are solid 
waste. All materials in the first category are solid waste. Materials in 
the second category are solid waste unless they are one of the five 
exclusions specified in Sec. 261.4(a).

                      Definition of Hazardous Waste

    If a person has determined that his material is a ``solid waste'', 
the next question he should ask is: ``Is the solid waste I handle a 
hazardous waste?''
    Hazardous waste is defined in Sec. 261.3 of this chapter. Section 
261.3 provides that, in general, a solid waste is a hazardous waste if: 
(1) It is, or contains, a hazardous waste listed in subpart D of part 
261 of this chapter, or (2) the waste exhibits any of the 
characteristics defined in subpart C of part 261. However, parts 260 and 
261 also contain provisions which exclude (Secs. 261.4(b), 260.20, and 
260.22) certain solid wastes from the definition of ``hazardous waste'', 
even though they are listed in subpart D or exhibit one or more of the 
characteristics defined in subpart C. Figure 2 depicts the interplay of 
these special provisions with the definition of ``hazardous waste''. It 
presents a series of questions which a person should ask himself 
concerning his waste. After doing so, the person should be able to 
determine if the solid waste he handles is a hazardous waste.

                       Hazardous Waste Regulations

    If this is the case, the person should look at Figure 3. Figure 3 
depicts the special provisions specified in the final part 261 rules for 
hazardous waste which:

1. Is generated by a small quantity generator
2. Is or is intended to be legitimately and beneficially used, re-used, 
recycled, or reclaimed
3. Is a sludge; is listed in part 261, subpart D; or is a mixture 
containing a waste listed in part 261, subpart D.

    For each of these Groups, Figure 3 indicates with which subtitle C 
regulations (if any) the person handling these wastes must comply. 
Figure 3 also explains that, if a person handles hazardous waste which 
is not included in any one of the above three categories, his waste is 
subject to the subtitle C regulations diagrammed in Figure 4.
    Figure 4 is a flowchart which identifies the three categories of 
activities regulated under the subtitle C rules, and the corresponding 
set of rules with which people in each of these categories must comply. 
It points out that all people who handle hazardous waste are either: (1) 
Generators of hazardous waste, (2) transporters of hazardous waste, (3) 
owners or operators of hazardous waste treatment, storage, or disposal 
facilities, or (4) a combination of the above. Figure 4 indicates that 
all of these people must notify EPA of their hazardous waste activities 
in accordance with the Section 3010 Notification Procedures (see 45 FR 
12746 et seq.), and obtain an EPA identification number.
    It should be noted that people handling wastes listed in subpart D 
of part 261 who have filed, or who intend to file an application to 
exempt their waste from regulation under the subtitle C rules, must also 
comply with the notification requirements of section 3010.
    If a person generates hazardous waste, Figure 4 indicates that he 
must comply with the part 262 rules. If he transports it, he must comply 
with the part 263 rules. The standards in both these parts are designed 
to ensure, among other things, proper recordkeeping and reporting, the 
use of a manifest system to track shipments of hazardous waste, the use 
of proper labels and containers, and the delivery of the waste to a 
permitted treatment, storage, or disposal facility.
    If a person owns or operates a facility which treats, stores, or 
disposes of hazardous waste, the standards with which he must comply 
depend on a number of factors. First of all, if the owner or operator of 
a storage facility is also the person who generates the waste, and the 
waste is stored at the facility

[[Page 25]]

for less than 90 days for subsequent shipment off-site, then the person 
must comply with Sec. 262.34 of the part 262 rules.
    All other owners or operators of treatment, storage, or disposal 
facilities must comply with either the part 264 or the part 265 rules. 
To determine with which of these sets of rules an owner or operator must 
comply, he must find out whether his facility qualifies for interim 
status. To qualify, the owner or operator must: (1) Have been treating, 
storing, or disposing of the hazardous waste, or commenced facility 
construction on or before October 21, 1976, (2) comply with the section 
3010 notification requirements, and (3) apply for a permit under part 
270 of this chapter.
    If the owner or operator has done all of the above, he qualifies for 
interim status, and he must comply with the part 265 rules. These rules 
contain administrative requirements, monitoring and closure standards, 
and an abbreviated set of technical and closure and post-closure cost 
estimate requirements. The owner or operator must comply with these 
standards until final administrative disposition of his permit 
application is made. If a permit is issued to the owner or operator, he 
must then comply with the permit which will be based on the part 264 
rules.
    If the owner or operator has not carried out the above three 
requirements, he does not qualify for interim status. Until he is issued 
a permit for his facility, the owner or operator must stop waste 
management operations (if any) at the facility, and send his hazardous 
waste (if any) to a facility whose owner or operator has interim status 
or to a storage facility following the part 262 rules.
    In order to apply for a permit, the owner or operator must comply 
with the procedures specified in part 270 of this chapter.
    It should be noted that the Agency will be periodically revising the 
rules depicted in Figures 3 and 4. All persons are encouraged to write 
to EPA to verify that the regulations which they are reading are up-to-
date. To obtain this verification, contact: Solid Waste Information, 
U.S. Environmental Protection Agency, 26 West St. Clair Street, 
Cincinnati, Ohio 45268 (513) 684-5362.

                           Subpart A--General



Sec. 261.1  Purpose and scope.

    (a) This part identifies those solid wastes which are subject to 
regulation as hazardous wastes under parts 262 through 265, 268, and 
parts 270, 271, and 124 of this chapter and which are subject to the 
notification requirements of section 3010 of RCRA. In this part:
    (1) Subpart A defines the terms ``solid waste'' and ``hazardous 
waste'', identifies those wastes which are excluded from regulation 
under parts 262 through 266, 268 and 270 and establishes special 
management requirements for hazardous waste produced by conditionally 
exempt small quantity generators and hazardous waste which is recycled.
    (2) Subpart B sets forth the criteria used by EPA to identify 
characteristics of hazardous waste and to list particular hazardous 
wastes.
    (3) Subpart C identifies characteristics of hazardous waste.
    (4) Subpart D lists particular hazardous wastes.
    (b)(1) The definition of solid waste contained in this part applies 
only to wastes that also are hazardous for purposes of the regulations 
implementing subtitle C of RCRA. For example, it does not apply to 
materials (such as non-hazardous scrap, paper, textiles, or rubber) that 
are not otherwise hazardous wastes and that are recycled.
    (2) This part identifies only some of the materials which are solid 
wastes and hazardous wastes under sections 3007, 3013, and 7003 of RCRA. 
A material which is not defined as a solid waste in this part, or is not 
a hazardous waste identified or listed in this part, is still a solid 
waste and a hazardous waste for purposes of these sections if:
    (i) In the case of sections 3007 and 3013, EPA has reason to believe 
that the material may be a solid waste within the meaning of section 
1004(27) of RCRA and a hazardous waste within the meaning of section 
1004(5) of RCRA; or
    (ii) In the case of section 7003, the statutory elements are 
established.
    (c) For the purposes of Secs. 261.2 and 261.6:
    (1) A ``spent material'' is any material that has been used and as a 
result of contamination can no longer serve the purpose for which it was 
produced without processing;
    (2) ``Sludge'' has the same meaning used in Sec. 260.10 of this 
chapter;
    (3) A ``by-product'' is a material that is not one of the primary 
products of a production process and is not solely or

[[Page 31]]

separately produced by the production process. Examples are process 
residues such as slags or distillation column bottoms. The term does not 
include a co-product that is produced for the general public's use and 
is ordinarily used in the form it is produced by the process.
    (4) A material is ``reclaimed'' if it is processed to recover a 
usable product, or if it is regenerated. Examples are recovery of lead 
values from spent batteries and regeneration of spent solvents.
    (5) A material is ``used or reused'' if it is either:
    (i) Employed as an ingredient (including use as an intermediate) in 
an industrial process to make a product (for example, distillation 
bottoms from one process used as feedstock in another process). However, 
a material will not satisfy this condition if distinct components of the 
material are recovered as separate end products (as when metals are 
recovered from metal-containing secondary materials); or
    (ii) Employed in a particular function or application as an 
effective substitute for a commercial product (for example, spent pickle 
liquor used as phosphorous precipitant and sludge conditioner in 
wastewater treatment).
    (6) ``Scrap metal'' is bits and pieces of metal parts (e.g.,) bars, 
turnings, rods, sheets, wire) or metal pieces that may be combined 
together with bolts or soldering (e.g., radiators, scrap automobiles, 
railroad box cars), which when worn or superfluous can be recycled.
    (7) A material is ``recycled'' if it is used, reused, or reclaimed.
    (8) A material is ``accumulated speculatively'' if it is accumulated 
before being recycled. A material is not accumulated speculatively, 
however, if the person accumulating it can show that the material is 
potentially recyclable and has a feasible means of being recycled; and 
that--during the calendar year (commencing on January 1)--the amount of 
material that is recycled, or transferred to a different site for 
recycling, equals at least 75 percent by weight or volume of the amount 
of that material accumulated at the beginning of the period. In 
calculating the percentage of turnover, the 75 percent requirement is to 
be applied to each material of the same type (e.g., slags from a single 
smelting process) that is recycled in the same way (i.e., from which the 
same material is recovered or that is used in the same way). Materials 
accumulating in units that would be exempt from regulation under 
Sec. 261.4(c) are not to be included in making the calculation. 
(Materials that are already defined as solid wastes also are not to be 
included in making the calculation.) Materials are no longer in this 
category once they are removed from accumulation for recycling, however.
    (9) ``Excluded scrap metal'' is processed scrap metal, unprocessed 
home scrap metal, and unprocessed prompt scrap metal.
    (10) ``Processed scrap metal'' is scrap metal which has been 
manually or physically altered to either separate it into distinct 
materials to enhance economic value or to improve the handling of 
materials. Processed scrap metal includes, but is not limited to scrap 
metal which has been baled, shredded, sheared, chopped, crushed, 
flattened, cut, melted, or separated by metal type (i.e., sorted), and, 
fines, drosses and related materials which have been agglomerated. 
(Note: shredded circuit boards being sent for recycling are not 
considered processed scrap metal. They are covered under the exclusion 
from the definition of solid waste for shredded circuit boards being 
recycled (Sec. 261.4(a)(13)).
    (11) ``Home scrap metal'' is scrap metal as generated by steel 
mills, foundries, and refineries such as turnings, cuttings, punchings, 
and borings.
    (12) ``Prompt scrap metal'' is scrap metal as generated by the metal 
working/fabrication industries and includes such scrap metal as 
turnings, cuttings, punchings, and borings. Prompt scrap is also known 
as industrial or new scrap metal.

Sec. 261.2  Definition of solid waste.

    (a)(1) A solid waste is any discarded material that is not excluded 
by Sec. 261.4(a) or that is not excluded by variance granted under 
Secs. 260.30 and 260.31.
    (2) A discarded material is any material which is:
    (i) Abandoned, as explained in paragraph (b) of this section; or
    (ii) Recycled, as explained in paragraph (c) of this section; or
    (iii) Considered inherently waste-like, as explained in paragraph 
(d) of this section; or
    (iv) A military munition identified as a solid waste in 40 CFR 
266.202.
    (b) Materials are solid waste if they are abandoned by being:
    (1) Disposed of; or
    (2) Burned or incinerated; or
    (3) Accumulated, stored, or treated (but not recycled) before or in 
lieu of being abandoned by being disposed of, burned, or incinerated.
    (c) Materials are solid wastes if they are recycled--or accumulated, 
stored, or treated before recycling--as specified in paragraphs (c)(1) 
through (4) of this section.
    (1) Used in a manner constituting disposal. (i) Materials noted with 
a ``*'' in Column 1 of Table I are solid wastes when they are:
    (A) Applied to or placed on the land in a manner that constitutes 
disposal; or
    (B) Used to produce products that are applied to or placed on the 
land or are otherwise contained in products that are applied to or 
placed on the land (in which cases the product itself remains a solid 
waste).
    (ii) However, commercial chemical products listed in Sec. 261.33 are 
not solid wastes if they are applied to the land and that is their 
ordinary manner of use.
    (2) Burning for energy recovery. (i) Materials noted with a ``*'' in 
column 2 of Table 1 are solid wastes when they are:
    (A) Burned to recover energy;
    (B) Used to produce a fuel or are otherwise contained in fuels (in 
which cases the fuel itself remains a solid waste).
    (ii) However, commercial chemical products listed in Sec. 261.33 are 
not solid wastes if they are themselves fuels.
    (3) Reclaimed. Materials noted with a ``*'' in column 3 of Table 1 
are solid wastes when reclaimed.
    (4) Accumulated speculatively. Materials noted with a ``*'' in 
column 4 of Table 1 are solid wastes when accumulated speculatively.

Note: The terms ``spent materials'', ``sludges'', ``by-products'', and ``scrap metal'' and ``processed scrap    
  metal'' are defined in Sec.  261.1.                                                                           

    (d) Inherently waste-like materials. The following materials are 
solid wastes when they are recycled in any manner:
    (1) Hazardous Waste Nos. F020, F021 (unless used as an ingredient to 
make a product at the site of generation), F022, F023, F026, and F028.
    (2) Secondary materials fed to a halogen acid furnace that exhibit a 
characteristic of a hazardous waste or are listed as a hazardous waste 
as defined in subparts C or D of this part, except for brominated 
material that meets the following criteria:

[[Page 33]]

    (i) The material must contain a bromine concentration of at least 
45%; and
    (ii) The material must contain less than a total of 1% of toxic 
organic compounds listed in appendix VIII; and
    (iii) The material is processed continually on-site in the halogen 
acid furnace via direct conveyance (hard piping).
    (3) The Administrator will use the following criteria to add wastes 
to that list:
    (i)(A) The materials are ordinarily disposed of, burned, or 
incinerated; or
    (B) The materials contain toxic constituents listed in appendix VIII 
of part 261 and these constituents are not ordinarily found in raw 
materials or products for which the materials substitute (or are found 
in raw materials or products in smaller concentrations) and are not used 
or reused during the recycling process; and
    (ii) The material may pose a substantial hazard to human health and 
the environment when recycled.
    (e) Materials that are not solid waste when recycled. (1) Materials 
are not solid wastes when they can be shown to be recycled by being:
    (i) Used or reused as ingredients in an industrial process to make a 
product, provided the materials are not being reclaimed; or
    (ii) Used or reused as effective substitutes for commercial 
products; or
    (iii) Returned to the original process from which they are 
generated, without first being reclaimed or land disposed. The material 
must be returned as a substitute for feedstock materials. In cases where 
the original process to which the material is returned is a secondary 
process, the materials must be managed such that there is no placement 
on the land.
    (2) The following materials are solid wastes, even if the recycling 
involves use, reuse, or return to the original process (described in 
paragraphs (e)(1) (i) through (iii) of this section):
    (i) Materials used in a manner constituting disposal, or used to 
produce products that are applied to the land; or
    (ii) Materials burned for energy recovery, used to produce a fuel, 
or contained in fuels; or
    (iii) Materials accumulated speculatively; or
    (iv) Materials listed in paragraphs (d)(1) and (d)(2) of this 
section.
    (f) Documentation of claims that materials are not solid wastes or 
are conditionally exempt from regulation. Respondents in actions to 
enforce regulations implementing subtitle C of RCRA who raise a claim 
that a certain material is not a solid waste, or is conditionally exempt 
from regulation, must demonstrate that there is a known market or 
disposition for the material, and that they meet the terms of the 
exclusion or exemption. In doing so, they must provide appropriate 
documentation (such as contracts showing that a second person uses the 
material as an ingredient in a production process) to demonstrate that 
the material is not a waste, or is exempt from regulation. In addition, 
owners or operators of facilities claiming that they actually are 
recycling materials must show that they have the necessary equipment to 
do so.

Sec. 261.3  Definition of hazardous waste.

    (a) A solid waste, as defined in Sec. 261.2, is a hazardous waste 
if:
    (1) It is not excluded from regulation as a hazardous waste under 
Sec. 261.4(b); and
    (2) It meets any of the following criteria:
    (i) It exhibits any of the characteristics of hazardous waste 
identified in subpart C except that any mixture of a waste from the 
extraction, beneficiation, and processing of ores and minerals excluded 
under Sec. 261.4(b)(7) and any other solid waste exhibiting a 
characteristic of hazardous waste under subpart C of this part only if 
it exhibits a characteristic that would not have been exhibited by the 
excluded waste alone if such mixture had not occurred or if it continues 
to exhibit any of the characteristics exhibited by the non-excluded 
wastes prior to mixture. Further, for the purposes of applying the 
Toxicity Characteristic to such mixtures, the mixture is also a 
hazardous waste if it exceeds the maximum concentration for any 
contaminant listed in table I to Sec. 261.24 that would not have been 
exceeded by the excluded waste alone if the mixture had not occurred or 
if it continues to exceed the maximum concentration for any contaminant 
exceeded by the nonexempt waste prior to mixture.
    (ii) It is listed in subpart D of this part and has not been 
excluded from the lists in subpart D of this part under Secs. 260.20 and 
260.22 of this chapter.
    (iii) It is a mixture of a solid waste and a hazardous waste that is 
listed in subpart D of this part solely because it exhibits one or more 
of the characteristics of hazardous waste identified in subpart C of 
this part, unless the resultant mixture no longer exhibits any 
characteristic of hazardous waste identified in subpart C of this part, 
or unless the solid waste is excluded from regulation under 
Sec. 261.4(b)(7) and the resultant mixture no longer exhibits any 
characteristic of hazardous waste identified in subpart C of this part 
for which the hazardous waste listed in subpart D of this part was 
listed. (However, nonwastewater mixtures are still subject to the 
requirements of part 268 of this chapter, even if they no longer exhibit 
a characteristic at the point of land disposal).
    (iv) It is a mixture of solid waste and one or more hazardous wastes 
listed in subpart D of this part and has not been excluded from 
paragraph (a)(2) of this section under Secs. 260.20 and 260.22 of this 
chapter; however, the following mixtures of solid wastes and hazardous 
wastes listed in subpart D of this part are not hazardous wastes (except 
by application of paragraph (a)(2) (i) or (ii) of this section) if the 
generator can demonstrate that the mixture consists of wastewater the 
discharge of which is subject to regulation under either section 402 or 
section 307(b) of the Clean Water Act (including wastewater at 
facilities which have eliminated the discharge of wastewater) and:
    (A) One or more of the following solvents listed in Sec. 261.31--
carbon tetrachloride, tetrachloroethylene, trichloroethylene--Provided, 
That the maximum total weekly usage of these solvents (other than the 
amounts that

[[Page 35]]

can be demonstrated not to be discharged to wastewater) divided by the 
average weekly flow of wastewater into the headworks of the facility's 
wastewater treatment or pretreatment system does not exceed 1 part per 
million; or
    (B) One or more of the following spent solvents listed in 
Sec. 261.31--methylene chloride, 1,1,1-trichloroethane, chlorobenzene, 
o-dichlorobenzene, cresols, cresylic acid, nitrobenzene, toluene, methyl 
ethyl ketone, carbon disulfide, isobutanol, pyridine, spent 
chlorofluorocarbon solvents--provided that the maximum total weekly 
usage of these solvents (other than the amounts that can be demonstrated 
not to be discharged to wastewater) divided by the average weekly flow 
of wastewater into the headworks of the facility's wastewater treatment 
or pretreatment system does not exceed 25 parts per million; or
    (C) One of the following wastes listed in Sec. 261.32--heat 
exchanger bundle cleaning sludge from the petroleum refining industry 
(EPA Hazardous Waste No. K050); or
    (D) A discarded commercial chemical product, or chemical 
intermediate listed in Sec. 261.33, arising from de minimis losses of 
these materials from manufacturing operations in which these materials 
are used as raw materials or are produced in the manufacturing process. 
For purposes of this paragraph (a)(2)(iv)(D), ``de minimis'' losses 
include those from normal material handling operations (e.g., spills 
from the unloading or transfer of materials from bins or other 
containers, leaks from pipes, valves or other devices used to transfer 
materials); minor leaks of process equipment, storage tanks or 
containers; leaks from well maintained pump packings and seals; sample 
purgings; relief device discharges; discharges from safety showers and 
rinsing and cleaning of personal safety equipment; and rinstate from 
empty containers or from containers that are rendered empty by that 
rinsing; or
    (E) Wastewater resulting from laboratory operations containing toxic 
(T) wastes listed in subpart D of this part, Provided, That the 
annualized average flow of laboratory wastewater does not exceed one 
percent of total wastewater flow into the headworks of the facility's 
wastewater treatment or pre-treatment system or provided the wastes, 
combined annualized average concentration does not exceed one part per 
million in the headworks of the facility's wastewater treatment or pre-
treatment facility. Toxic (T) wastes used in laboratories that are 
demonstrated not to be discharged to wastewater are not to be included 
in this calculation; or
    (F) One or more of the following wastes listed in Sec. 261.32--
wastewaters from the production of carbamates and carbamoyl oximes (EPA 
Hazardous Waste No. K157)--Provided that the maximum weekly usage of 
formaldehyde, methyl chloride, methylene chloride, and triethylamine 
(including all amounts that can not be demonstrated to be reacted in the 
process, destroyed through treatment, or is recovered, i.e., what is 
discharged or volatilized) divided by the average weekly flow of process 
wastewater prior to any dilutions into the headworks of the facility's 
wastewater treatment system does not exceed a total of 5 parts per 
million by weight; or
    (G) Wastewaters derived from the treatment of one or more of the 
following wastes listed in Sec. 261.32--organic waste (including heavy 
ends, still bottoms, light ends, spent solvents, filtrates, and 
decantates) from the production of carbamates and carbamoyl oximes (EPA 
Hazardous Waste No. K156).--Provided, that the maximum concentration of 
formaldehyde, methyl chloride, methylene chloride, and triethylamine 
prior to any dilutions into the headworks of the facility's wastewater 
treatment system does not exceed a total of 5 milligrams per liter.
    (v) Rebuttable presumption for used oil. Used oil containing more 
than 1000 ppm total halogens is presumed to be a hazardous waste because 
it has been mixed with halogenated hazardous waste listed in subpart D 
of part 261 of this chapter. Persons may rebut this presumption by 
demonstrating that the used oil does not contain hazardous waste (for 
example, by using an analytical method from SW-846, Third Edition, to 
show that the used oil does not contain significant concentrations of 
halogenated

[[Page 36]]

hazardous constituents listed in appendix VIII of part 261 of this 
chapter). EPA Publication SW-846, Third Edition, is available for the 
cost of $110.00 from the Government Printing Office, Superintendent of 
Documents, PO Box 371954, Pittsburgh, PA 15250-7954. 202-512-1800 
(document number 955-001-00000-1).
    (A) The rebuttable presumption does not apply to metalworking oils/
fluids containing chlorinated paraffins, if they are processed, through 
a tolling agreement, to reclaim metalworking oils/fluids. The 
presumption does apply to metalworking oils/fluids if such oils/fluids 
are recycled in any other manner, or disposed.
    (B) The rebuttable presumption does not apply to used oils 
contaminated with chlorofluorocarbons (CFCs) removed from refrigeration 
units where the CFCs are destined for reclamation. The rebuttable 
presumption does apply to used oils contaminated with CFCs that have 
been mixed with used oil from sources other than refrigeration units.
    (b) A solid waste which is not excluded from regulation under 
paragraph (a)(1) of this section becomes a hazardous waste when any of 
the following events occur:
    (1) In the case of a waste listed in subpart D of this part, when 
the waste first meets the listing description set forth in subpart D of 
this part.
    (2) In the case of a mixture of solid waste and one or more listed 
hazardous wastes, when a hazardous waste listed in subpart D is first 
added to the solid waste.
    (3) In the case of any other waste (including a waste mixture), when 
the waste exhibits any of the characteristics identified in subpart C of 
this part.
    (c) Unless and until it meets the criteria of paragraph (d) of this 
section:
    (1) A hazardous waste will remain a hazardous waste.
    (2)(i) Except as otherwise provided in paragraph (c)(2)(ii) of this 
section, any solid waste generated from the treatment, storage, or 
disposal of a hazardous waste, including any sludge, spill residue, ash, 
emission control dust, or leachate (but not including precipitation run-
off) is a hazardous waste. (However, materials that are reclaimed from 
solid wastes and that are used beneficially are not solid wastes and 
hence are not hazardous wastes under this provision unless the reclaimed 
material is burned for energy recovery or used in a manner constituting 
disposal.)
    (ii) The following solid wastes are not hazardous even though they 
are generated from the treatment, storage, or disposal of a hazardous 
waste, unless they exhibit one or more of the characteristics of 
hazardous waste:
    (A) Waste pickle liquor sludge generated by lime stabilization of 
spent pickle liquor from the iron and steel industry (SIC Codes 331 and 
332).
    (B) Waste from burning any of the materials exempted from regulation 
by Sec. 261.6(a)(3)(iv) through (vi).
    (C)(1) Nonwastewater residues, such as slag, resulting from high 
temperature metals recovery (HTMR) processing of K061, K062 or F006 
waste, in units identified as rotary kilns, flame reactors, electric 
furnaces, plasma arc furnaces, slag reactors, rotary hearth furnace/
electric furnace combinations or industrial furnaces (as defined in 
paragraphs (6), (7), and (13) of the definition for ``Industrial 
furnace'' in 40 CFR 260.10), that are disposed in subtitle D units, 
provided that these residues meet the generic exclusion levels 
identified in the tables in this paragraph for all constituents, and 
exhibit no characteristics of hazardous waste. Testing requirements must 
be incorporated in a facility's waste analysis plan or a generator's 
self-implementing waste analysis plan; at a minimum, composite samples 
of residues must be collected and analyzed quarterly and/or when the 
process or operation generating the waste changes. Persons claiming this 
exclusion in an enforcement action will have the burden of proving by 
clear and convincing evidence that the material meets all of the 
exclusion requirements.

    (2) A one-time notification and certification must be placed in the 
facility's files and sent to the EPA region or authorized state for 
K061, K062 or F006 HTMR residues that meet the generic exclusion levels 
for all constituents and do not exhibit any characteristics that are 
sent to subtitle D units. The notification and certification that is 
placed in the generators or treaters files must be updated if the 
process or operation generating the waste changes and/or if the subtitle 
D unit receiving the waste changes. However, the generator or treater 
need only notify the EPA region or an authorized state on an annual 
basis if such changes occur. Such notification and certification should 
be sent to the EPA region or authorized state by the end of the calendar 
year, but no later than December 31. The notification must include the 
following information: The name and address of the subtitle D unit 
receiving the waste shipments; the EPA Hazardous Waste Number(s) and 
treatability group(s) at the initial point of generation; and, the 
treatment standards applicable to the waste at the initial point of 
generation. The certification must be signed by an authorized 
representative and must state as follows: ``I certify under penalty of 
law that the generic exclusion levels for all constituents have been met 
without impermissible dilution and that no characteristic of hazardous 
waste is exhibited. I am aware that there are significant penalties for 
submitting a false certification, including the possibility of fine and 
imprisonment.''
    (D) Biological treatment sludge from the treatment of one of the 
following wastes listed in Sec. 261.32--organic waste (including heavy 
ends, still bottoms, light ends, spent solvents, filtrates, and 
decantates) from the production of carbamates and carbamoyl oximes (EPA 
Hazardous Waste No. K156), and wastewaters from the production of 
carbamates and carbamoyl oximes (EPA Hazardous Waste No. K157).
    (d) Any solid waste described in paragraph (c) of this section is 
not a hazardous waste if it meets the following criteria:
    (1) In the case of any solid waste, it does not exhibit any of the 
characteristics of hazardous waste identified in subpart C of this part. 
(However, wastes that exhibit a characteristic at the point of 
generation may still be subject to the requirements of part 268, even if 
they no longer exhibit a characteristic at the point of land disposal.)
    (2) In the case of a waste which is a listed waste under subpart D 
of this part, contains a waste listed under subpart D of this part or is 
derived from a waste listed in subpart D of this part, it also has been 
excluded from paragraph (c) of this section under Secs. 260.20 and 
260.22 of this chapter.
    (e)  [Reserved]
    (f) Notwithstanding paragraphs (a) through (d) of this section and 
provided the debris as defined in part 268 of this chapter does not 
exhibit a characteristic identified at subpart C of this part, the 
following materials are not subject to regulation under 40 CFR parts 
260, 261 to 266, 268, or 270:
    (1) Hazardous debris as defined in part 268 of this chapter that has 
been treated using one of the required extraction or destruction 
technologies specified in Table 1 of Sec. 268.45 of this chapter; 
persons claiming this exclusion in an enforcement action will have the 
burden of proving by clear and convincing evidence that the material

[[Page 38]]

meets all of the exclusion requirements; or
    (2) Debris as defined in part 268 of this chapter that the Regional 
Administrator, considering the extent of contamination, has determined 
is no longer contaminated with hazardous waste.

Sec. 261.4  Exclusions.

    (a) Materials which are not solid wastes. The following materials 
are not solid wastes for the purpose of this part:
    (1)(i) Domestic sewage; and
    (ii) Any mixture of domestic sewage and other wastes that passes 
through a sewer system to a publicly-owned treatment works for 
treatment. ``Domestic sewage'' means untreated sanitary wastes that pass 
through a sewer system.
    (2) Industrial wastewater discharges that are point source 
discharges subject to regulation under section 402 of the Clean Water 
Act, as amended.

[Comment: This exclusion applies only to the actual point source 
discharge. It does not exclude industrial wastewaters while they are 
being collected, stored or treated before discharge, nor does it exclude 
sludges that are generated by industrial wastewater treatment.]

    (3) Irrigation return flows.
    (4) Source, special nuclear or by-product material as defined by the 
Atomic Energy Act of 1954, as amended, 42 U.S.C. 2011 et seq.

removed from the ground as part of the extraction process.
    (6) Pulping liquors (i.e., black liquor) that are reclaimed in a 
pulping liquor recovery furnace and then reused in the pulping process, 
unless it is accumulated speculatively as defined in Sec. 261.1(c) of 
this chapter.
    (7) Spent sulfuric acid used to produce virgin sulfuric acid, unless 
it is accumulated speculatively as defined in Sec. 261.1(c) of this 
chapter.
    (8) Secondary materials that are reclaimed and returned to the 
original process or processes in which they were generated where they 
are reused in the production process provided:
    (i) Only tank storage is involved, and the entire process through 
completion of reclamation is closed by being entirely connected with 
pipes or other comparable enclosed means of conveyance;
    (ii) Reclamation does not involve controlled flame combustion (such 
as occurs in boilers, industrial furnaces, or incinerators);
    (iii) The secondary materials are never accumulated in such tanks 
for over twelve months without being reclaimed; and
    (iv) The reclaimed material is not used to produce a fuel, or used 
to produce products that are used in a manner constituting disposal.
    (9)(i) Spent wood preserving solutions that have been reclaimed and 
are reused for their original intended purpose; and
    (ii) Wastewaters from the wood preserving process that have been 
reclaimed and are reused to treat wood.
    (10) EPA Hazardous Waste Nos. K060, K087, K141, K142, K143, K144, 
K145, K147, and K148, and any wastes from the coke by-products processes 
that are hazardous only because they exhibit the Toxicity Characteristic 
(TC) specified in section 261.24 of this part when, subsequent to 
generation, these materials are recycled to coke ovens, to the tar 
recovery process as a feedstock to produce coal tar, or mixed with coal 
tar prior to the tar's sale or refining. This exclusion is conditioned 
on there being no land disposal of the wastes from the point they are 
generated to the point they are recycled to coke ovens or tar recovery 
or refining processes, or mixed with coal tar.
    (11) Nonwastewater splash condenser dross residue from the treatment 
of K061 in high temperature metals recovery units, provided it is 
shipped in drums (if shipped) and not land disposed before recovery.

production, and from transportation incident thereto, which is to be 
inserted into the petroleum refining process (SIC Code 2911) at

[[Page 39]]

or before a point (other than direct insertion into a coker) where 
contaminants are removed. This exclusion applies to recovered oil stored 
or transported prior to insertion, except that the oil must not be 
stored in a manner involving placement on the land, and must not be 
accumulated speculatively, before being so recycled. Recovered oil is 
oil that has been reclaimed from secondary materials (such as 
wastewater) generated from normal petroleum refining, exploration and 
production, and transportation practices. Recovered oil includes oil 
that is recovered from refinery wastewater collection and treatment 
systems, oil recovered from oil and gas drilling operations, and oil 
recovered from wastes removed from crude oil storage tanks. Recovered 
oil does not include (among other things) oil-bearing hazardous waste 
listed in 40 CFR part 261 D (e.g., K048-K052, F037, F038). However, oil 
recovered from such wastes may be considered recovered oil. Recovered

refuse-derived fuel) or reused. ``Household waste'' means any material 
(including garbage, trash and sanitary wastes in septic tanks) derived 
from households (including single and multiple residences, hotels and 
motels, bunkhouses, ranger stations, crew quarters, campgrounds, picnic 
grounds and day-use recreation areas). A resource recovery facility 
managing municipal solid waste shall not be deemed to be treating, 
storing, disposing of, or otherwise managing hazardous wastes for the 
purposes of regulation under this subtitle, if such facility:
    (i) Receives and burns only
    (A) Household waste (from single and multiple dwellings, hotels, 
motels, and other residential sources) and
    (B) Solid waste from commercial or industrial sources that does not 
contain hazardous waste; and
    (ii) Such facility does not accept hazardous wastes and the owner or 
operator of such facility has established contractual requirements or

with the exploration, development, or production of crude oil, natural 
gas or geothermal energy.
    (6)(i) Wastes which fail the test for the Toxicity Characteristic 
because chromium is present or are listed in subpart D due to the 
presence of chromium, which do not fail the test for the Toxicity 
Characteristic for any other constituent or are not listed due to the 
presence of any other constituent, and which do not fail the test for 
any other characteristic, if it is shown by a waste generator or by 
waste generators that:
    (A) The chromium in the waste is exclusively (or nearly exclusively) 
trivalent chromium; and
    (B) The waste is generated from an industrial process which uses 
trivalent chromium exlcusively (or nearly exclusively) and the process

for the sample was completed, or no more than one year (two years for 
treatability studies involving bioremediation) have elapsed since the 
generator or sample collector shipped the sample to the laboratory or 
testing facility, whichever date first occurs. Up to 500 kg of treated 
material from a particular waste stream from treatability studies may be 
archived for future evaluation up to five years from the date of initial 
receipt. Quantities of materials archived are counted against the total 
storage limit for the facility.
    (6) The treatability study does not involve the placement of 
hazardous waste on the land or open burning of hazardous waste.
    (7) The facility maintains records for 3 years following completion 
of each study that show compliance with the treatment rate limits and

                  Waste and for Listing Hazardous Waste

(b) [Reserved]



Sec. 261.10  Criteria for identifying the characteristics of hazardous waste.

    (a) The Administrator shall identify and define a characteristic of 
hazardous waste in subpart C only upon determining that:
    (1) A solid waste that exhibits the characteristic may:
    (i) Cause, or significantly contribute to, an increase in mortality 
or an increase in serious irreversible, or incapacitating reversible, 
illness; or
    (ii) Pose a substantial present or potential hazard to human health 
or the environment when it is improperly treated, stored, transported, 
disposed of or otherwise managed; and
    (2) The characteristic can be:
    (i) Measured by an available standardized test method which is 
reasonably within the capability of generators of solid waste or private 
sector laboratories that are available to serve generators of solid 
waste; or
    (ii) Reasonably detected by generators of solid waste through their 
knowledge of their waste.
    (b) [Reserved].



Sec. 261.11  Criteria for listing hazardous waste.

    (a) The Administrator shall list a solid waste as a hazardous waste 
only upon determining that the solid waste meets one of the following 
criteria:
    (1) It exhibits any of the characteristics of hazardous waste 
identified in subpart C.
    (2) It has been found to be fatal to humans in low doses or, in the 
absence of data on human toxicity, it has been shown in studies to have 
an oral LD 50 toxicity (rat) of less than 50 milligrams per kilogram, an 
inhalation LC 50 toxicity (rat) of less than 2 milligrams per liter, or 
a dermal LD 50 toxicity (rabbit) of less than 200 milligrams per 
kilogram or is otherwise capable of causing or significantly 
contributing to an increase in serious irreversible, or incapacitating 
reversible, illness. (Waste listed in accordance with these criteria 
will be designated Acute Hazardous Waste.)
    (3) It contains any of the toxic constituents listed in appendix 
VIII and, after considering the following factors, the Administrator 
concludes that the waste is capable of posing a substantial present or 
potential hazard to human health or the environment when improperly 
treated, stored, transported or disposed of, or otherwise managed:
    (i) The nature of the toxicity presented by the constituent.

[[Page 51]]

    (ii) The concentration of the constituent in the waste.
    (iii) The potential of the constituent or any toxic degradation 
product of the constituent to migrate from the waste into the 
environment under the types of improper management considered in 
paragraph (a)(3)(vii) of this section.
    (iv) The persistence of the constituent or any toxic degradation 
product of the constituent.
    (v) The potential for the constituent or any toxic degradation 
product of the constituent to degrade into non-harmful constituents and 
the rate of degradation.
    (vi) The degree to which the constituent or any degradation product 
of the constituent bioaccumulates in ecosystems.
    (vii) The plausible types of improper management to which the waste 
could be subjected.
    (viii) The quantities of the waste generated at individual 
generation sites or on a regional or national basis.
    (ix) The nature and severity of the human health and environmental 
damage that has occurred as a result of the improper management of 
wastes containing the constituent.
    (x) Action taken by other governmental agencies or regulatory 
programs based on the health or environmental hazard posed by the waste 
or waste constituent.
    (xi) Such other factors as may be appropriate.

Substances will be listed on appendix VIII only if they have been shown 
in scientific studies to have toxic, carcinogenic, mutagenic or 
teratogenic effects on humans or other life forms.
    (Wastes listed in accordance with these criteria will be designated 
Toxic wastes.)
    (b) The Administrator may list classes or types of solid waste as 
hazardous waste if he has reason to believe that individual wastes, 
within the class or type of waste, typically or frequently are hazardous 
under the definition of hazardous waste found in section 1004(5) of the 
Act.
    (c) The Administrator will use the criteria for listing specified in 
this section to establish the exclusion limits referred to in 
Sec. 261.5(c).

from regulation as a hazardous waste under Sec. 261.4(b), is a hazardous 
waste if it exhibits any of the characteristics identified in this 
subpart.

[Comment: Sec. 262.11 of this chapter sets forth the generator's 
responsibility to determine whether his waste exhibits one or more of 
the characteristics identified in this subpart]

    (b) A hazardous waste which is identified by a characteristic in 
this subpart is assigned every EPA Hazardous Waste Number that is 
applicable as set forth in this subpart. This number must be used in 
complying with the notification requirements of section 3010 of the Act 
and all applicable recordkeeping and reporting requirements under parts 
262 through 265, 268, and 270 of this chapter.
    (c) For purposes of this subpart, the Administrator will consider a 
sample obtained using any of the applicable sampling methods specified 
in appendix I to be a representative sample within the meaning of part 
260 of this chapter.

[Comment: Since the appendix I sampling methods are not being formally 
adopted by the Administrator, a person who desires to employ an 
alternative sampling method is not required to demonstrate the 
equivalency of his method under the procedures set forth in Secs. 260.20 
and 260.21.]

Sec. 261.33  Discarded commercial chemical products, off-specification species, container residues, and spill residues thereof.

    The following materials or items are hazardous wastes if and when 
they are discarded or intended to be discarded as described in 
Sec. 261.2(a)(2)(i), when they are mixed with waste oil or used oil or 
other material and applied to the land for dust suppression or road 
treatment, when they are otherwise applied to the land in lieu of their 
original intended use or when they are contained in products that are 
applied to the land in lieu of their original intended use, or when, in 
lieu of their original intended use, they are produced for use as (or as 
a component of) a fuel, distributed for use as a fuel, or burned as a 
fuel.
    (a) Any commercial chemical product, or manufacturing chemical 
intermediate having the generic name listed in paragraph (e) or (f) of 
this section.
    (b) Any off-specification commercial chemical product or 
manufacturing chemical intermediate which, if it met specifications, 
would have the generic name listed in paragraph (e) or (f) of this 
section.
    (c) Any residue remaining in a container or in an inner liner 
removed from a container that has held any commercial chemical product 
or manufacturing chemical intermediate having the generic name listed in 
paragraphs (e) or (f) of this section, unless the container is empty as 
defined in Sec. 261.7(b) of this chapter.

[Comment: Unless the residue is being beneficially used or reused, or 
legitimately recycled or reclaimed; or being accumulated, stored, 
transported or treated prior to such use, re-use, recycling or 
reclamation, EPA considers the residue to be intended for discard, and 
thus, a hazardous waste. An example of a legitimate re-use of the 
residue would be where the residue remains in the container and the 
container is used to hold the same commercial chemical product or 
manufacturing chemical intermediate it previously held. An example of 
the discard of the residue would be where the drum is sent to a drum 
reconditioner who reconditions the drum but discards the residue.]

    (d) Any residue or contaminated soil, water or other debris 
resulting from the cleanup of a spill into or on any land or water of 
any commercial chemical product or manufacturing chemical intermediate 
having the generic name listed in paragraph (e) or (f) of this section, 
or any residue or contaminated soil, water or other debris resulting 
from the cleanup of a spill, into or on any land or water, of any off-
specification chemical product and manufacturing chemical intermediate 
which, if it met specifications, would have the generic name listed in 
paragraph (e) or (f) of this section.

[Comment: The phrase ``commercial chemical product or manufacturing 
chemical intermediate having the generic name listed in .  .  .'' refers 
to a chemical substance which is manufactured or formulated for 
commercial or manufacturing use which consists of the commercially pure 
grade of the chemical, any technical grades of the chemical that are 
produced or marketed, and all formulations in which the chemical is the 
sole active ingredient. It does not refer to a material, such as a 
manufacturing process waste, that contains any of the substances listed 
in paragraph (e) or (f). Where a manufacturing process waste is deemed 
to be a hazardous waste because it contains a substance listed in 
paragraph (e) or (f), such waste will be listed in either Sec. 261.31 or 
Sec. 261.32 or will be identified as a hazardous waste by the 
characteristics set forth in subpart C of this part.]

section of this volume.



Sec. 261.35  Deletion of certain hazardous waste codes following equipment cleaning and replacement.

    (a) Wastes from wood preserving processes at plants that do not 
resume or initiate use of chlorophenolic preservatives will not meet the 
listing definition of F032 once the generator has met all of the 
requirements of paragraphs (b) and (c) of this section. These wastes 
may, however, continue to meet another hazardous waste listing 
description or may exhibit one or more of the hazardous waste 
characteristics.
    (b) Generators must either clean or replace all process equipment 
that may have come into contact with chlorophenolic formulations or 
constituents thereof, including, but not limited to, treatment 
cylinders, sumps, tanks, piping systems, drip pads, fork lifts, and 
trams, in a manner that minimizes or eliminates the escape of hazardous 
waste or constituents, leachate, contaminated drippage, or hazardous 
waste decomposition products to the ground water, surface water, or 
atmosphere.
    (1) Generators shall do one of the following:
    (i) Prepare and follow an equipment cleaning plan and clean 
equipment in accordance with this section;
    (ii) Prepare and follow an equipment replacement plan and replace 
equipment in accordance with this section; or
    (iii) Document cleaning and replacement in accordance with this 
section, carried out after termination of use of chlorophenolic 
preservations.
    (2) Cleaning Requirements.
    (i) Prepare and sign a written equipment cleaning plan that 
describes:
    (A) The equipment to be cleaned;
    (B) How the equipment will be cleaned;
    (C) The solvent to be used in cleaning;
    (D) How solvent rinses will be tested; and
    (E) How cleaning residues will be disposed.
    (ii) Equipment must be cleaned as follows:
    (A) Remove all visible residues from process equipment;
    (B) Rinse process equipment with an appropriate solvent until 
dioxins and dibenzofurans are not detected in the final solvent rinse.
    (iii) Analytical requirements.
    (A) Rinses must be tested in accordance with SW-846, Method 8290.
    (B) ``Not detected'' means at or below the lower method calibration 
limit (MCL) in Method 8290, Table 1.
    (iv) The generator must manage all residues from the cleaning 
process as F032 waste.
    (3) Replacement requirements.
    (i) Prepare and sign a written equipment replacement plan that 
describes:
    (A) The equipment to be replaced;
    (B) How the equipment will be replaced; and
    (C) How the equipment will be disposed.
    (ii) The generator must manage the discarded equipment as F032 
waste.
    (4) Documentation requirements.
    (i) Document that previous equipment cleaning and/or replacement was 
performed in accordance with this section and occurred after cessation 
of use of chlorophenolic preservatives.
    (c) The generator must maintain the following records documenting 
the cleaning and replacement as part of the facility's operating record:

[[Page 73]]

    (1) The name and address of the facility;
    (2) Formulations previously used and the date on which their use 
ceased in each process at the plant;
    (3) Formulations currently used in each process at the plant;
    (4) The equipment cleaning or replacement plan;
    (5) The name and address of any persons who conducted the cleaning 
and replacement;
    (6) The dates on which cleaning and replacement were accomplished;
    (7) The dates of sampling and testing;
    (8) A description of the sample handling and preparation techniques, 
including techniques used for extraction, containerization, 
preservation, and chain-of-custody of the samples;
    (9) A description of the tests performed, the date the tests were 
performed, and the results of the tests;
    (10) The name and model numbers of the instrument(s) used in 
performing the tests;
    (11) QA/QC documentation; and
    (12) The following statement signed by the generator or his 
authorized representative:

    I certify under penalty of law that all process equipment required 
to be cleaned or replaced under 40 CFR 261.35 was cleaned or replaced as 
represented in the equipment cleaning and replacement plan and 
accompanying documentation. I am aware that there are significant 
penalties for providing false information, including the possibility of 
fine or imprisonment.

                                       composite samples more frequently
                                       to demonstrate that smaller      
                                       batches of waste are non-        
                                       hazardous.                       
                                        (C) Annual Verification Testing:
                                       In order to confirm that the     
                                       characteristics of the treated   
                                       waste do not change              
                                       significantly, BSC must, on an   
                                       annual basis, analyze a          
                                       representative composite sample  
                                       of stabilized filter cake for all
                                       TC constituents listed in 40 CFR 
                                       Sec.  261.24 using the method    
                                       specified therein. This composite
                                       sample must represent the        
                                       stabilized filter cake generated 
                                       over one week.

                                       in Condition (1)(A), if BSC      
                                       decides to significantly change  
                                       the stabilization process (e.g., 
                                       stabilization reagents) developed
                                       under Condition (1), then BSC    
                                       must notify EPA in writing prior 
                                       to instituting the change. After 
                                       written approval by EPA, BSC may 
                                       manage waste generated from the  
                                       changed process as non-hazardous 
                                       under this exclusion, provided   
                                       the other conditions of this     
                                       exclusion are fulfilled.

                                       valid:                           
                                      (1) Testing: Sample collection and
                                       analyses, including quality      
                                       control (QC) procedures, must be 
                                       performed according to SW-846    
                                       methodologies.                   
                                      (A) Sample Collection: Each batch 
                                       of waste generated over a four-  
                                       week period must be collected in 
                                       containers with a maximum        
                                       capacity of 20-cubic yards. At   
                                       the end of the four-week period, 
                                       each container must be divided   
                                       into four quadrants and a single,
                                       full-depth core sample shall be  
                                       collected from each quadrant. All
                                       of the full-depth core samples   
                                       then must be composited under    
                                       laboratory conditions to produce 
                                       one representative composite     
                                       sample for the four-week period. 
                                      (B) Sample Analysis: Each four-   
                                       week composite sample must be    
                                       analyzed for all of the          
                                       constituents listed in Condition 
                                       (3). The analytical data,        
                                       including quality control        
                                       information, must be compiled and
                                       maintained on site for a minimum 
                                       of three years. These data must  
                                       be furnished upon request by any 
                                       employee or representative of EPA
                                       or state of Pennsylvania.        
                                      (2) Waste Holding: The dewatered  
                                       filter cake waste must be stored 
                                       as hazardous until the           
                                       verification analyses are        
                                       completed.                       
                                      If the four-week composite sample 
                                       does not exceed any of the       
                                       delisting levels set in Condition
                                       (3), the filter cake waste       
                                       corresponding to this sample may 
                                       be managed and disposed of in    
                                       accordance with all applicable   
                                       solid waste regulations. If the  
                                       four-week composite sample       
                                       exceeds any of the delisting     
                                       levels set in Condition (3), the 
                                       filter cake waste generated      
                                       during the time period           
                                       corresponding to the four-week   
                                       composite sample must be         
                                       retreated until it meets these   
                                       levels (analyses must be         
                                       repeated) or managed and disposed

                                       generated but for which analyses 
                                       are not complete or valid must be
                                       managed and disposed of in       
                                       accordance with subtitle C of    
                                       RCRA, until valid analyses       
                                       demonstrate that the waste meets 
                                       the delisting levels.

                                      2. Waste Holding and Handling:    
                                       Texas Eastman must store in      
                                       accordance with its RCRA permit, 
                                       or continue to dispose of as     
                                       hazardous all FBI ash generated  
                                       until the Initial and Subsequent 
                                       Verification Testing described in
                                       Paragraph 4 and 5 below is       
                                       completed and valid analyses     
                                       demonstrate that all Verification
                                       Testing Conditions are satisfied.
                                       After completion of Initial and  
                                       Subsequent Verification Testing, 
                                       if the levels of constituents    
                                       measured in the samples of the   
                                       FBI ash do not exceed the levels 
                                       set forth in Paragraph 1 above,  
                                       and written notification is given
                                       by EPA, then the waste is non-   
                                       hazardous and may be managed and 
                                       disposed of in accordance with   
                                       all applicable solid waste       
                                       regulations.                     
                                      3. Verification Testing           
                                       Requirements: Sample collection  
                                       and analyses, including quality  
                                       control procedures, must be      
                                       performed according to SW-846    
                                       methodologies. If EPA judges the 
                                       incineration process to be       
                                       effective under the operating    
                                       conditions used during the       
                                       initial verification testing     
                                       described in Paragraph 4 below,  
                                       Texas Eastman may replace the    
                                       testing required in Paragraph 4  
                                       with the testing required in     
                                       Paragraph 5 below. Texas Eastman 
                                       must, however, continue to test  
                                       as specified in Paragraph 4 until
                                       notified by EPA in writing that  
                                       testing in Paragraph 4 may be    
                                       replaced by the testing described
                                       in Paragraph 5.                  
                                      4. Initial Verification Testing:  
                                       During the first 40 operating    
                                       days of the FBI incinerator after
                                       the final exclusion is granted,  
                                       Texas Eastman must collect and   
                                       analyze daily composites of the  
                                       FBI ash. Daily composites must be
                                       composed of representative grab  
                                       samples collected every 6 hours  
                                       during each 24-hour FBI operating
                                       cycle. The FBI ash must be       
                                       analyzed, prior to disposal of   
                                       the ash, for all constituents    
                                       listed in Paragraph 1. Texas     
                                       Eastman must report the          
                                       operational and analytical test  
                                       data, including quality control  
                                       information, obtained during this
                                       initial period no later than 90  
                                       days after receipt of the        
                                       validated analytical results.    
                                      5. Subsequent Verification        
                                       Testing: Following the completion
                                       of the Initial Verification      
                                       Testing, Texas Eastman may       
                                       request to monitor operating     
                                       conditions and analyze samples   
                                       representative of each quarter of
                                       operation during the first year  
                                       of ash generation. The samples   
                                       must represent the untreated ash 
                                       generated over one quarter.      
                                       Following written notification   
                                       from EPA, Texas Eastman may begin
                                       the quarterly testing described  
                                       in this Paragraph.               
                                      6. Termination of Organic Testing:
                                       Texas Eastman must continue      
                                       testing as required under        
                                       Paragraph 5 for organic          
                                       constituents specified in        
                                       Paragraph 1 until the analyses   
                                       submitted under Paragraph 5 show 
                                       a minimum of two consecutive     
                                       quarterly samples below the      
                                       delisting levels in Paragraph 1. 
                                       Texas Eastman may then request   
                                       that quarterly organic testing be
                                       terminated. After EPA notifies   
                                       Texas Eastman in writing it may  
                                       terminate quarterly organic      
                                       testing.                         
                                      7. Annual Testing: Following      
                                       termination of quarterly testing 
                                       under either Paragraphs 5 or 6,  
                                       Texas Eastman must continue to   
                                       test a representative composite  
                                       sample for all constituents      
                                       listed in Paragraph 1 (including 
                                       organics) on an annual basis (no 
                                       later than twelve months after   
                                       the date that the final exclusion
                                       is effective).                   
                                      8. Changes in Operating

                                       operation, Bethlehem must        
                                       implement a testing program for  
                                       the petitioned waste. This       
                                       testing program must meet the    
                                       following conditions for the     
                                       exclusion to be valid:

                                      (A) Initial Testing: During the   
                                       first four weeks of operation of 
                                       the full-scale treatment system, 
                                       Bethlehem must collect           
                                       representative grab samples of   
                                       each treated batch of the CSEAFD 
                                       and composite the grab samples   
                                       daily. The daily composites,     
                                       prior to disposal, must be       
                                       analyzed for the EP leachate     
                                       concentrations of all the EP     
                                       toxic metals, nickel and cyanide 
                                       (using distilled water in the    
                                       cyanide extractions), and the

                                       cyanide. Analyses must be        
                                       performed according to SW-846    
                                       methodologies. Bethlehem must    
                                       report the analytical test data  
                                       obtained during this initial     
                                       period no later than 90 days     
                                       after the treatment of the first 
                                       full-scale batch.                
                                      (B) Subsequent Testing: Bethlehem 
                                       must collect representative grab 
                                       samples from every treated batch 
                                       of CSEAFD generated daily and    
                                       composite all of the grab samples
                                       to produce a weekly composite    
                                       sample. Bethlehem then must      
                                       analyze each weekly composite    
                                       sample for the EP leachate       
                                       concentrations of all the EP     
                                       toxic metals and nickel. Analyses
                                       must be performed according to SW-
                                       846 methodologies. The analytical
                                       data, including all quality      
                                       control information, must be     
                                       compiled and maintained on site  
                                       for a minimum of three years.    
                                       These data must be furnished upon
                                       request and made available for

                                       methodologies. Bethlehem must    
                                       report the analytical test data  
                                       obtained during this initial     
                                       period no later than 90 days     
                                       after the treatment of the first 
                                       full-scale batch.                
                                      (B) Subsequent Testing: Bethlehem 
                                       must collect representative grab 
                                       samples from every treated batch 
                                       of CSEAFD generated daily and    
                                       composite all of the grab samples
                                       to produce a weekly composite    
                                       sample. Bethlehem then must      
                                       analyze each weekly composite    
                                       sample for the EP leachate       
                                       concentrations of all the EP     
                                       toxic metals and nickel. Analyses
                                       must be performed according to SW-
                                       846 methodologies. The analytical
                                       data, including all quality      
                                       control information, must be

                                      (B) Subsequent Testing: CF&I must 
                                       collect representative grab      
                                       samples from every treated batch 
                                       of CSEAFD generated daily and    
                                       composite all of the grab samples

                                       sample. CF&I then must analyze   
                                       each weekly composite sample for 
                                       the EP leachate concentrations of
                                       all of the EP toxic metals and   
                                       nickel. Analyses must be         
                                       performed according to SW-846    
                                       methodologies. The analytical    
                                       data, including all quality      
                                       control information, must be     
                                       compiled and maintained on site  
                                       for a minimum of three years.    
                                       These data must be furnished upon
                                       request and made available for

                                       the wastes at levels of          
                                       regulatory concern while the     
                                       treatment facility is in         
                                       operation, DOE must implement a  
                                       testing program. This testing    
                                       program must meet the following  
                                       conditions for the exclusion to  
                                       be valid:                        
                                      (1) Testing: Sample collection and
                                       analyses (including quality      
                                       control (QC) procedures) must be 
                                       performed according to SW-846 (or
                                       other EPA-approved)              
                                       methodologies. If EPA judges the 
                                       treatment process to be effective
                                       under the operating conditions   
                                       used during the initial          
                                       verification testing, DOE may    
                                       replace the testing required in  
                                       Condition (1)(A) with the testing
                                       required in Condition (1)(B). DOE
                                       must continue to test as         
                                       specified in Condition (1)(A)    
                                       until notified by EPA in writing 
                                       that testing in Condition (1) (A)
                                       may be replaced by Condition     
                                       (1)(B).                          
                                      (A) Initial Verification Testing: 
                                       During the period required to    
                                       fill the first three verification
                                       tanks (each designed to hold     
                                       approximately 650,000 gallons)   
                                       with effluents generated from an 
                                       on-line, full-scale Effluent     
                                       Treatment Facility (ETF), DOE    
                                       must monitor the range of typical
                                       operating conditions for the ETF.
                                       DOE must collect a representative
                                       sample from each of the first    
                                       three verification tanks filled  
                                       with ETF effluents. The samples  
                                       must be analyzed, prior to       
                                       disposal of ETF effluents, for   
                                       all constituents listed in       
                                       Condition (3). DOE must report   
                                       the operational and analytical   
                                       test data, including quality     
                                       control information, obtained    
                                       during this initial period no    
                                       later than 90 days after the     
                                       first verification tank is filled
                                       with ETF effluents.              
                                      (B) Subsequent Verification       
                                       Testing: Following notification  
                                       by EPA, DOE may substitute the   
                                       testing conditions in this       
                                       condition for (1)(A). DOE must   
                                       continue to monitor operating    
                                       conditions, and collect and      
                                       analyze representative samples   
                                       from every tenth verification    
                                       tank filled with ETF effluents.  
                                       These representative samples must
                                       be analyzed, prior to disposal of
                                       ETF effluents, for all           
                                       constituents listed in Condition 
                                       (3). If all constituent levels in
                                       a sample do not meet the         
                                       delisting levels specified in    
                                       Condition (3), DOE must analyze  
                                       representative samples from the  
                                       following two verification tanks 
                                       generated prior to disposal. DOE 
                                       may also collect and analyze     
                                       representative samples more      
                                       frequently.

                                       DOE must store as hazardous all  
                                       ETF effluents generated during   
                                       verification testing (as         
                                       specified in Conditions (1)(A)   
                                       and (1)(B)), that is until valid 
                                       analyses demonstrate that        
                                       Condition (3) is satisfied. If   
                                       the levels of hazardous          
                                       constituents in the samples of

                                       in Condition (3), then the ETF   
                                       effluents are not hazardous and  
                                       may be managed and disposed of in
                                       accordance with all applicable   
                                       solid waste regulations. If

                                       treated until the ETF effluents  
                                       meet these levels. Following re- 
                                       treatment, DOE must repeat       
                                       analyses in Condition (3) prior  
                                       to disposal.

                                       test as specified in Condition   
                                       (1)(A), including testing for    
                                       organics in Conditions (3)(B) and
                                       (3)(C), until and unless notified
                                       by EPA in writing that testing in
                                       Condition (1)(A) may be replaced 
                                       by Condition (1)(B), or that     
                                       testing for organics may be      
                                       terminated as described in (1)(C)
                                       (to the extent directed by EPA). 
                                      (A) Initial Verification Testing: 
                                       During at least the first 40     
                                       operating days of full-scale     
                                       operation of the thermal         
                                       desorption unit, Marathon must   
                                       monitor the operating conditions 
                                       and analyze 5-day composites of  
                                       residual solids. 5-day composites
                                       must be composed of              
                                       representative grab samples      
                                       collected from every batch during
                                       each 5-day period of operation.  
                                       The samples must be analyzed     
                                       prior to disposal of the residual
                                       solids for constituents listed in
                                       Condition (3). Marathon must     
                                       report the operational and       
                                       analytical test data, including  
                                       quality control information,     
                                       obtained during this initial     
                                       period no later than 90 days     
                                       after the treatment of the first 
                                       full-scale batch.                
                                      (B) Subsequent Verification       
                                       Testing: Following notification  
                                       by EPA, Marathon may substitute  
                                       the testing conditions in (1)(B) 
                                       for (1)(A). Marathon must        
                                       continue to monitor operating    
                                       conditions, and analyze samples  
                                       representative of each month of  
                                       operation. The samples must be   
                                       composed of representative grab  
                                       samples collected during at least
                                       the first five days of operation 
                                       of each month. These monthly     
                                       representative samples must be   
                                       analyzed for the constituents    
                                       listed in Condition (3) prior to 
                                       the disposal of the residual     
                                       solids. Marathon may, at its     
                                       discretion, analyze composite    
                                       samples gathered more frequently 
                                       to demonstrate that smaller      
                                       batches of waste are             
                                       nonhazardous.                    
                                      (C) Termination of Organic        
                                       Testing: Marathon must continue  
                                       testing as required under        
                                       Condition (1)(B) for organic     
                                       constituents specified in        
                                       Conditions (3)(B) and (3)(C)     
                                       until the analyses submitted     
                                       under Condition (1)(B) show a    
                                       minimum of four consecutive      
                                       monthly representative samples   
                                       with levels of specific          
                                       constituents significantly below 
                                       the delisting levels in          
                                       Conditions (3)(B) and (3)(C), and
                                       EPA notifies Marathon in writing 
                                       that monthly testing for specific
                                       organic constituents may be      
                                       terminated. Following termination
                                       of monthly testing, Marathon must
                                       continue to test a representative
                                       5-day composite sample for all   
                                       constituents listed in Conditions
                                       (3)(B) and (3)(C) on an annual   
                                       basis. If delisting levels for   
                                       any constituents listed in       
                                       Conditions (3)(B) and (3)(C) are 
                                       exceeded in the annual sample,   
                                       Marathon must reinstitute        
                                       complete testing as required in  
                                       Condition (1)(B).

                                      (2) Waste Holding and Handling:   
                                       Marathon must store as hazardous 
                                       all residual solids generated    
                                       until verification testing (as   
                                       specified in Conditions (1)(A)   
                                       and (1)(B)) is completed and     
                                       valid analysis demonstrates that 
                                       Condition (3) is satisfied. If   
                                       the levels of hazardous          
                                       constituents in the samples of   
                                       residual solids are below all of 
                                       the levels set forth in Condition
                                       (3), then the residual solids are
                                       non-hazardous and may be managed 
                                       and disposed of in accordance    
                                       with all applicable solid waste  
                                       regulations. If hazardous        
                                       constituent levels in any 5-day  
                                       composite or other representative
                                       sample equal or exceed any of the
                                       delisting levels set in Condition
                                       (3), the residual solids         
                                       generated during the             
                                       corresponding time period must be
                                       retreated and/or stabilized as   
                                       allowed below, until the residual
                                       solids meet these levels, or     
                                       managed and disposed of in       
                                       accordance with Subtitle C of    
                                       RCRA.                            
                                      If the residual solids contain    
                                       leachable inorganic              
                                       concentrations at or above the   
                                       delisting levels set forth in    
                                       Condition (3)(A), then Marathon  
                                       may stabilize the material with  
                                       Type 1 portland cement as        
                                       demonstrated in the petition to  
                                       immobilize the metals. Following 
                                       stabilization, Marathon must     
                                       repeat analyses in Condition     
                                       (3)(A) prior to disposal.

                                       to produce three separate weekly 
                                       composite samples (of each type  
                                       of K071 waste). The three weekly 
                                       composite samples, prior to      
                                       disposal, must be analyzed for   
                                       the EP leachate concentrations of
                                       all the EP toxic metals (except  
                                       mercury), nickel and cyanide

                                       cyanide extractions), and the    
                                       total constituent concentrations 
                                       of reactive sulfide and reactive 
                                       cyanide. Occidental must report  
                                       the waste volumes produced and   
                                       the analytical test data,        
                                       including all quality control    
                                       data, obtained during this       
                                       initial period, no later than 90 
                                       days after the treatment of the  
                                       first full-scale batch.          
                                      (B) Collect representative grab   
                                       samples of each batch of the     
                                       three treated wastestreams (NaCl-
                                       SC, NACl-TM and KCl-TM) and      
                                       composite the grab samples to

                                       basis. The three daily composite 
                                       samples, prior to disposal, must 
                                       be analyzed for the EP leachate  
                                       concentration of mercury.        
                                       Occidental must report the waste 
                                       volumes produced and the         
                                       analytical test data, including  
                                       all quality control data,        
                                       obtained during this initial     
                                       period, no later than 90 days    
                                       after the treatment of the first 
                                       full-scale batch.                
                                      (2) Subsequent Testing: After the

                                       must be analyzed, prior to the   
                                       disposal of the kiln residue, for
                                       all constituents listed in       
                                       Condition (4). Reynolds must     
                                       report the analytical test data, 
                                       including quality control        
                                       information, obtained during this
                                       initial period no later than 90  
                                       days after the treatment of the  
                                       first full-scale batch of        
                                       untreated spent potliner.        
                                      (B) Subsequent Verification       
                                       Testing: Following notification  
                                       by EPA, Reynolds may substitute  
                                       the testing conditions in (2)(B) 
                                       for (2)(A). Reynolds must collect
                                       and analyze both daily and weekly
                                       composites of kiln residue. Daily
                                       composites must be composed of   
                                       representative grab samples      
                                       collected every 6 hours during a 
                                       24-hour kiln operating cycle and 
                                       these samples must be analyzed,  
                                       prior to the disposal of the kiln
                                       residue, for leachable           
                                       concentrations of cyanide and    
                                       fluoride. Weekly composites must 
                                       be composed of representative    
                                       grab samples collected every 6   
                                       hours during a 24-hour kiln      
                                       operating cycle for each day in  
                                       the week that the kiln is        
                                       operating.                       
                                        The weekly samples must be      
                                       analyzed, prior to the disposal  
                                       of the kiln residue, for the     
                                       leachable concentrations of the  
                                       inorganics listed in Condition   
                                       (4)(A) and leachable levels of   
                                       the semi-volatile organic        
                                       compounds listed in Condition    
                                       (4)(B). Analyses of both daily   
                                       and weekly samples must be       
                                       completed prior to the disposal  
                                       of waste generated during that   
                                       week as set forth in Condition   
                                       (3). The analytical data,        
                                       including quality control        
                                       information, must be compiled,   
                                       summarized, and maintained on    
                                       site for a minimum of five years.
                                       These data must be furnished upon
                                       request and made available for   
                                       inspection by any employee or    
                                       representative of EPA or the

                                      (3) Waste Holding and Handling:   
                                       Reynolds must store, as          
                                       hazardous, all kiln residue      
                                       generated until verification     
                                       testing (as specified in         
                                       Condition (2)(A) and (2)(B)) is  
                                       completed and compared, by the   
                                       petitioner, with the delisting   
                                       levels set forth in Condition    
                                       (4). If the levels of hazardous  
                                       constituents measured in the     
                                       samples of kiln residue generated
                                       do not exceed any of the levels  
                                       set forth in Condition (4), then 
                                       the kiln residue is non-hazardous
                                       and may be managed and           
                                        disposed of in accordance with  
                                       all applicable solid waste       
                                       regulations. If hazardous        
                                       constituent levels in any daily  
                                       or weekly sample exceed any of   
                                       the delisting levels set in      
                                       Condition (4), the kiln residue  
                                       generated during the time period 
                                       corresponding to this sample must
                                       be retreated until it meets these
                                       levels (analyses must be         
                                       repeated) or managed and disposed
                                       of in accordance with Subtitle C 
                                       of RCRA. Kiln residue which is   
                                       generated but for which the      
                                       required analysis is not complete
                                       or valid must be managed and     
                                       disposed of in accordance with   
                                       Subtitle C of RCRA, until valid  
                                       analysis demonstrates that       
                                       Condition (4) is satisfied.

                                       report the analytical test data  
                                       obtained during this initial     
                                       period no later than 90 days     
                                       after the treatment of the first 
                                       full-scale batch.                
                                      (B) Subsequent testing: Roanoke   
                                       must collect representative grab 
                                       samples from every treated batch 
                                       of CSEAFD generated daily and    
                                       composite all of the grab samples
                                       to produce a weekly composite    
                                       sample. Roanoke then must analyze
                                       each weekly composite sample for 
                                       all of the EP toxic metals and   
                                       nickel. Analyses must be         
                                       performed according to SW-846    
                                       methodologies. The analytical    
                                       data, including all quality      
                                       control information, must be     
                                       compiled and maintained on site  
                                       for a minimum of three years.    
                                       These data must be furnished upon
                                       request and made available for

                                       analyses (including quality      
                                       control (QC) procedures) must be 
                                       performed according to SW-846    
                                       methodologies.                   
                                      (A) Initial Testing: During the   
                                       first four weeks of operation of 
                                       the full-scale treatment system, 
                                       USX must collect representative  
                                       grab samples of each treated     
                                       batch of the CSEAFD and composite
                                       the grab samples daily. The daily
                                       composites, prior to disposal,   
                                       must be analyzed for the EP      
                                       leachate concentrations of all   
                                       the EP toxic metals, nickel, and 
                                       cyanide (using distilled water in
                                       the cyanide extractions), and the
                                       total concentrations of reactive 
                                       sulfide and reactive cyanide. USX
                                       must report the analytical test  
                                       data, including quality control  
                                       information, obtained during this
                                       initial period no later than 90  
                                       days after the treatment of the  
                                       first full-scale batch.          
                                      (B) Subsequent Testing: USX must  
                                       collect representative grab      
                                       samples from every treated batch 
                                       of CSEAFD generated daily and    
                                       composite all of the grab samples
                                       to produce a weekly composite    
                                       sample. USX then must analyze    
                                       each weekly composite sample for 
                                       all of the EP toxic metals, and  
                                       nickel. The analytical data,     
                                       including quality control        
                                       information, must be compiled and
                                       maintained on site for a minimum 
                                       of three years. These data must  
                                       be furnished upon request and

                                       17, 1986. To assure that mercury 
                                       levels in this waste are         
                                       maintained at acceptable levels, 
                                       the following conditions apply to
                                       this exclusion: Each batch of    
                                       treated brine clarifier muds and 
                                       saturator insolubles must be     
                                       tested (by the extraction        
                                       procedure) prior to disposal and 
                                       the leachate concentration of    
                                       mercury must be less than or     
                                       equal to 0.0129 ppm. If the waste
                                       does not meet this requirement,  
                                       then it must be re-treated or    
                                       disposed of as hazardous. This   
                                       exclusion does not apply to      
                                       wastes for which either of these 
                                       conditions is not satisfied.

    (a) These regulations establish standards for generators of 
hazardous waste.
    (b) 40 CFR 261.5(c) and (d) must be used to determine the 
applicability of provisions of this part that are dependent on 
calculations of the quantity of hazardous waste generated per month.

[[Page 122]]

    (c) A generator who treats, stores, or disposes of hazardous waste 
on-site must only comply with the following sections of this part with 
respect to that waste: Section 262.11 for determining whether or not he 
has a hazardous waste, Sec. 262.12 for obtaining an EPA identification 
number, Sec. 262.34 for accumulation of hazardous waste, Sec. 262.40 (c) 
and (d) for recordkeeping, Sec. 262.43 for additional reporting, and if 
applicable, Sec. 262.70 for farmers.
    (d) Any person who exports or imports hazardous waste subject to the 
Federal manifesting requirements of part 262, or subject to the 
universal waste management standards of 40 CFR Part 273, or subject to 
State requirements analogous to 40 CFR Part 273, to or from the 
countries listed in Sec. 262.58(a)(1) for recovery must comply with 
subpart H of this part.
    (e) Any person who imports hazardous waste into the United States 
must comply with the standards applicable to generators established in 
this part.
    (f) A farmer who generates waste pesticides which are hazardous

Sec. 262.11  Hazardous waste determination.

    A person who generates a solid waste, as defined in 40 CFR 261.2, 
must determine if that waste is a hazardous waste using the following 
method:
    (a) He should first determine if the waste is excluded from 
regulation under 40 CFR 261.4.
    (b) He must then determine if the waste is listed as a hazardous 
waste in subpart D of 40 CFR part 261.

    Note: Even if the waste is listed, the generator still has an 
opportunity under 40 CFR 260.22 to demonstrate to the Administrator that 
the waste from his particular facility or operation is not a hazardous 
waste.

    (c) For purposes of compliance with 40 CFR part 268, or if the waste 
is not listed in subpart D of 40 CFR part 261, the generator must then 
determine whether the waste is identified in subpart C of 40 CFR part 
261 by either:
    (1) Testing the waste according to the methods set forth in subpart 
C of 40 CFR part 261, or according to an equivalent method approved by 
the Administrator under 40 CFR 260.21; or
    (2) Applying knowledge of the hazard characteristic of the waste in 
light of the materials or the processes used.
    (d) If the waste is determined to be hazardous, the generator must 
refer to parts 261, 264, 265, 266, 268, and 273 of this chapter for 
possible exclusions or restrictions pertaining to management of the 
specific waste.

Sec. 262.80  Applicability.

    (a) The requirements of this subpart apply to imports and exports of 
wastes that are considered hazardous under U.S. national procedures and 
are destined for recovery operations in the countries listed in 
Sec. 262.58(a)(1). A waste is considered hazardous under U.S. national 
procedures if it meets the Federal definition of hazardous waste in 40 
CFR 261.3 and it is subject to either the Federal manifesting 
requirements at 40 CFR Part 262, Subpart B, to the universal waste 
management standards of 40 CFR Part 273, or to State requirements 
analogous to 40 CFR Part 273.
    (b) Any person (notifier, consignee, or recovery facility operator) 
who mixes two or more wastes (including hazardous and non-hazardous 
wastes) or otherwise subjects two or more wastes (including hazardous 
and non-hazardous wastes) to physical or chemical transformation 
operations, and thereby creates a new hazardous waste, becomes a 
generator and assumes all subsequent generator duties under RCRA and any 
notifier duties, if applicable, under this subpart.

Sec. 262.82  General conditions.

    (a) Scope. The level of control for exports and imports of waste is 
indicated by assignment of the waste to a green, amber, or red list and 
by U.S. national procedures as defined in Sec. 262.80(a). The green, 
amber, and red lists are incorporated by reference in Sec. 262.89 (e).
    (1) Wastes on the green list are subject to existing controls 
normally applied to commercial transactions, except as provided below:
    (i) Green-list wastes that are considered hazardous under U.S. 
national procedures are subject to amber-list controls.
    (ii) Green-list waste that are sufficiently contaminated or mixed 
with amber-list wastes, such that the waste or waste mixture is 
considered hazardous under U.S. national procedures, are subject to 
amber-list controls.
    (iii) Green-list wastes that are sufficiently contaminated or mixed 
with other wastes subject to red-list controls such that the waste or 
waste mixture is considered hazardous under U.S. national procedures 
must be handled in accordance with the red-list controls.
    (2) Wastes on the amber list that are considered hazardous under 
U.S. national procedures as defined in Sec. 262.80(a) are subject to the 
amber-list controls of this Subpart.
    (i) If amber-list wastes are sufficiently contaminated or mixed with 
other wastes subject to red-list controls such that the waste or waste 
mixture is considered hazardous under U.S. national procedures, the 
wastes must be handled in accordance with the red-list controls.
    (ii) [Reserved].
    (3) Wastes on the red list that are considered hazardous under U.S. 
national procedures as defined in Sec. 262.80(a) are subject to the red-
list controls of this subpart.

    Note to paragraph (a)(3): Some wastes on the amber or red lists are 
not listed or otherwise identified as hazardous under RCRA (e.g., 
polychlorinated biphenyls) and therefore are not subject to the amber- 
or red-list controls of this subpart. Regardless of the status of the 
waste under RCRA, however, other Federal environmental statutes (e.g.,

[[Page 135]]

the Toxic Substances Control Act) may restrict certain waste imports or 
exports. Such restrictions continue to apply without regard to this 
Subpart.

    (4) Wastes not yet assigned to a list are eligible for transfrontier 
movements, as follows:
    (i) If such wastes are considered hazardous under U.S. national 
procedures as defined in Sec. 262.80(a), these wastes are subject to the 
red-list controls; or
    (ii) If such wastes are not considered hazardous under U.S. national 
procedures as defined in Sec. 262.80(a), such wastes may move as though 
they appeared on the green list.
    (b) General conditions applicable to transfrontier movements of 
hazardous waste.
    (1) The waste must be destined for recovery operations at a facility 
that, under applicable domestic law, is operating or is authorized to 
operate in the importing country;
    (2) The transfrontier movement must be in compliance with applicable 
international transport agreements; and

    Note to paragraph (b)(2): These international agreements include, 
but are not limited to, the Chicago Convention (1944), ADR (1957), ADNR 
(1970), MARPOL Convention (1973/1978), SOLAS Convention (1974), IMDG 
Code (1985), COTIF (1985), and RID (1985).

    (3) Any transit of waste through a non-OECD member country must be 
conducted in compliance with all applicable international and national 
laws and regulations.
    (c) Provisions relating to re-export for recovery to a third 
country.
    (1) Re-export of wastes subject to the amber-list control system 
from the U.S., as the importing country, to a third country listed in 
Sec. 262.58(a)(1) may occur only after a notifier in the U.S. provides 
notification to and obtains consent of the competent authorities in the 
third country, the original exporting country, and new transit 
countries. The notification must comply with the notice and consent 
procedures in Sec. 262.83 for all concerned countries and the original 
exporting country. The competent authorities of the original exporting 
country as well as the competent authorities of all other concerned 
countries have 30 days to object to the proposed movement.
    (i) The 30-day period begins once the competent authorities of both 
the initial exporting country and new importing country issue 
Acknowledgements of Receipt of the notification.
    (ii) The transfrontier movement may commence if no objection has 
been lodged after the 30-day period has passed or immediately after 
written consent is received from all relevant OECD importing and transit 
countries.
    (2) Re-export of waste subject to the red-list control system from 
the original importing country to a third country listed in 
Sec. 262.58(a)(1) may occur only following notification of the competent 
authorities of the third country, the original exporting country, and 
new transit countries by a notifier in the original importing country in 
accordance with Sec. 262.83. The transfrontier movement may not proceed 
until receipt by the original importing country of written consent from 
the competent authorities of the third country, the original exporting 
country, and new transit countries.
    (3) In the case of re-export of amber or red-list wastes to a 
country other than those in Sec. 262.58(a)(1), notification to and 
consent of the competent authorities of the original OECD member country 
of export and any OECD member countries of transit is required as 
specified in paragraphs (c)(1) and (c)(2) of this section in addition to 
compliance with all international agreements and arrangements to which 
the first importing OECD member country is a party and all applicable 
regulatory requirements for exports from the first importing country.



Sec. 262.83  Notification and consent.

    (a) Applicability. Consent must be obtained from the competent 
authorities of the relevant OECD importing and transit countries prior 
to exporting hazardous waste destined for recovery operations subject to 
this Subpart. Hazardous wastes subject to amber-list controls are 
subject to the requirements of paragraph (b) of this section; hazardous 
wastes subject to red-list controls are subject to the requirements of 
paragraph (c) of this section; and wastes not identified on any list are 
subject to the requirements of paragraph (d) of this section.

[[Page 136]]

    (b) Amber-list wastes. The export from the U.S. of hazardous wastes 
as described in Sec. 262.80(a) that appear on the amber list is 
prohibited unless the notification and consent requirements of paragraph 
(b)(1) or paragraph (b)(2) of this section are met.
    (1) Transactions requiring specific consent:
    (i) Notification. At least 45 days prior to commencement of the 
transfrontier movement, the notifier must provide written notification 
in English of the proposed transfrontier movement to the Office of 
Enforcement and Compliance Assurance, Office of Compliance, Enforcement 
Planning, Targeting and Data Division (2222A), Environmental Protection 
Agency, 401 M St., SW., Washington, DC 20460, with the words 
``Attention: OECD Export Notification'' prominently displayed on the 
envelope. This notification must include all of the information 
identified in paragraph (e) of this section. In cases where wastes 
having similar physical and chemical characteristics, the same United 
Nations classification, and the same RCRA waste codes are to be sent 
periodically to the same recovery facility by the same notifier, the 
notifier may submit one notification of intent to export these wastes in 
multiple shipments during a period of up to one year.
    (ii) Tacit consent. If no objection has been lodged by any concerned 
country (i.e., exporting, importing, or transit countries) to a 
notification provided pursuant to paragraph (b)(1)(i) of this section 
within 30 days after the date of issuance of the Acknowledgment of 
Receipt of notification by the competent authority of the importing 
country, the transfrontier movement may commence. Tacit consent expires 
one calendar year after the close of the 30 day period; renotification 
and renewal of all consents is required for exports after that date.
    (iii) Written consent. If the competent authorities of all the 
relevant OECD importing and transit countries provide written consent in 
a period less than 30 days, the transfrontier movement may commence 
immediately after all necessary consents are received. Written consent 
expires for each relevant OECD importing and transit country one 
calendar year after the date of that country's consent unless otherwise 
specified; renotification and renewal of each expired consent is 
required for exports after that date.
    (2) Shipments to facilities pre-approved by the competent 
authorities of the importing countries to accept specific wastes for 
recovery:
    (i) The notifier must provide EPA the information identified in 
paragraph (e) of this section in English, at least 10 days in advance of 
commencing shipment to a pre-approved facility. The notification should 
indicate that the recovery facility is pre-approved, and may apply to a 
single specific shipment or to multiple shipments as described in 
paragraph (b)(1)(i) of this section. This information must be sent to 
the Office of Enforcement and Compliance Assurance, Office of 
Compliance, Enforcement Planning, Targeting and Data Division (2222A), 
Environmental Protection Agency, 401 M St., SW., Washington, DC 20460, 
with the words ``OECD Export Notification--Pre-approved Facility'' 
prominently displayed on the envelope.
    (ii) Shipments may commence after the notification required in 
paragraph (b)(1)(i) of this section has been received by the competent 
authorities of all concerned countries, unless the notifier has received 
information indicating that the competent authorities of one or more 
concerned countries objects to the shipment.
    (c) Red-list wastes. The export from the U.S. of hazardous wastes as 
described in Sec. 262.80(a) that appear on the red list is prohibited 
unless notice is given pursuant to paragraph (b)(1)(i) of this section 
and the notifier receives written consent from the importing country and 
any transit countries prior to commencement of the transfrontier 
movement.
    (d) Unlisted wastes. Wastes not assigned to the green, amber, or red 
list that are considered hazardous under U.S. national procedures as 
defined in Sec. 262.80(a) are subject to the notification and consent 
requirements established for red-list wastes in accordance with 
paragraph (c) of this section. Unlisted wastes that are not considered 
hazardous under U.S. national procedures as defined in Sec. 262.80(a) 
are not

[[Page 137]]

subject to amber or red controls when exported or imported.
    (e) Notification information. Notifications submitted under this 
section must include:
    (1) Serial number or other accepted identifier of the notification 
form;
    (2) Notifier name and EPA identification number (if applicable), 
address, and telephone and telefax numbers;

    Note to paragraph (e)(12): The U.S. does not currently require 
financial assurance; however, U.S. exporters may be asked by other 
governments to provide and certify to such assurance as a condition of 
obtaining consent to a proposed movement.



Sec. 262.84  Tracking document.

    (a) All U.S. parties subject to the contract provisions of 
Sec. 262.85 must ensure that a tracking document meeting the conditions 
of Sec. 262.84(b) accompanies each transfrontier shipment of wastes 
subject to amber-list or red-list controls from the initiation of the 
shipment until it reaches the final recovery facility, including cases 
in which the waste is stored and/or exchanged by the consignee prior to 
shipment to the final recovery facility, except as provided in 
Secs. 262.84(a)(1) and (2).
    (1) For shipments of hazardous waste within the U.S. solely by water 
(bulk shipments only) the generator must forward the tracking document 
with the manifest to the last water (bulk shipment) transporter to 
handle the waste in the U.S. if exported by water, (in accordance with 
the manifest routing procedures at Sec. 262.23(c)).
    (2) For rail shipments of hazardous waste within the U.S. which 
originate at the site of generation, the generator must forward the 
tracking document with the manifest (in accordance with the routing 
procedures for the manifest in Sec. 262.23(d)) to the next non-rail 
transporter, if any, or the last rail transporter to handle the waste in 
the U.S. if exported by rail.
    (b) The tracking document must include all information required 
under Sec. 262.83 (for notification), and the following:

    (c) Notifiers also must comply with the special manifest 
requirements of 40 CFR 262.54(a), (b), (c), (e), and (i) and consignees 
must comply with the import requirements of 40 CFR part 262, subpart F.
    (d) Each U.S. person that has physical custody of the waste from the 
time the movement commences until it arrives at the recovery facility 
must sign the tracking document (e.g. transporter, consignee, and owner 
or operator of the recovery facility).
    (e) Within 3 working days of the receipt of imports subject to this 
Subpart, the owner or operator of the U.S. recovery facility must send 
signed copies of the tracking document to the notifier, to the Office of 
Enforcement and Compliance Assurance, Office of Compliance, Enforcement 
Planning, Targeting and Data Division (2222A), Environmental Protection 
Agency, 401 M St., SW., Washington, DC 20460, and to the competent 
authorities of the exporting and transit countries.



Sec. 262.85  Contracts.

    (a) Transfrontier movements of hazardous wastes subject to amber or 
red control procedures are prohibited unless they occur under the terms 
of a valid written contract, chain of contracts, or equivalent 
arrangements (when the movement occurs between parties controlled by the 
same corporate or legal entity). Such contracts or equivalent 
arrangements must be executed by the notifier and the owner or operator 
of the recovery facility, and must specify responsibilities for each. 
Contracts or equivalent arrangements are valid for the purposes of this 
section only if persons assuming obligations under the contracts or 
equivalent arrangements have appropriate legal status to conduct the 
operations specified in the contract or equivalent arrangement.
    (b) Contracts or equivalent arrangements must specify the name and 
EPA ID number, where available, of:
    (1) The generator of each type of waste;
    (2) Each person who will have physical custody of the wastes;
    (3) Each person who will have legal control of the wastes; and
    (4) The recovery facility.
    (c) Contracts or equivalent arrangements must specify which party to 
the contract will assume responsibility for alternate management of the 
wastes if its disposition cannot be carried out as described in the 
notification of intent to export. In such cases, contracts must specify 
that:
    (1) The person having actual possession or physical control over the 
wastes will immediately inform the notifier and the competent 
authorities of the exporting and importing countries and, if the wastes 
are located in a country of transit, the competent authorities of that 
country; and
    (2) The person specified in the contract will assume responsibility 
for the adequate management of the wastes in compliance with applicable 
laws and regulations including, if necessary, arranging their return to 
the original country of export.
    (d) Contracts must specify that the consignee will provide the 
notification required in Sec. 262.82(c) prior to re-export of controlled 
wastes to a third country.
    (e) Contracts or equivalent arrangements must include provisions for 
financial guarantees, if required by the

[[Page 139]]

competent authorities of any concerned country, in accordance with 
applicable national or international law requirements.

    Note to paragraph (e): Financial guarantees so required are intended 
to provide for alternate recycling, disposal or other means of sound 
management of the wastes in cases where arrangements for the shipment 
and the recovery operations cannot be carried out as foreseen. The U.S. 
does not require such financial guarantees at this time; however, some 
OECD countries do. It is the responsibility of the notifier to ascertain 
and comply with such requirements; in some cases, transporters or 
consignees may refuse to enter into the necessary contracts absent 
specific references or certifications to financial guarantees.

    (f) Contracts or equivalent arrangements must contain provisions 
requiring each contracting party to comply with all applicable 
requirements of this subpart.
    (g) Upon request by EPA, U.S. notifiers, consignees, or recovery 
facilities must submit to EPA copies of contracts, chain of contracts, 
or equivalent arrangements (when the movement occurs between parties 
controlled by the same corporate or legal entity). Information contained 
in the contracts or equivalent arrangements for which a claim of 
confidentiality is asserted accordance with 40 CFR 2.203(b) will be 
treated as confidential and will be disclosed by EPA only as provided in 
40 CFR 260.2.

    Note to paragraph (g): Although the U.S. does not require routine 
submission of contracts at this time, OECD Council Decision C(92)39/
FINAL allows members to impose such requirements. When other OECD 
countries require submission of partial or complete copies of the 
contract as a condition to granting consent to proposed movements, EPA 
will request the required information; absent submission of such 
information, some OECD countries may deny consent for the proposed 
movement.



Sec. 262.86  Provisions relating to recognized traders.

    (a) A recognized trader who takes physical custody of a waste and 
conducts recovery operations (including storage prior to recovery) is 
acting as the owner or operator of a recovery facility and must be so 
authorized in accordance with all applicable Federal laws.
    (b) A recognized trader acting as a notifier or consignee for 
transfrontier shipments of waste must comply with all the requirements 
of this Subpart associated with being a notifier or consignee.



Sec. 262.87  Reporting and recordkeeping.

    (a) Annual reports. For all waste movements subject to this Subpart, 
persons (e.g., notifiers, recognized traders) who meet the definition of 
primary exporter in Sec. 262.51 shall file an annual report with the

                           Subpart A--General



Sec. 263.10  Scope.

    (a) These regulations establish standards which apply to persons 
transporting hazardous waste within the United States if the 
transportation requires a manifest under 40 CFR part 262.

    Note: The regulations set forth in parts 262 and 263 establish the 
responsibilities of generators and transporters of hazardous waste in 
the handling, transportation, and management of that waste. In these 
regulations, EPA has expressly adopted certain regulations of the 
Department of Transportation (DOT) governing the transportation of 
hazardous materials. These regulations concern, among other things, 
labeling, marking, placarding, using proper containers, and reporting 
discharges. EPA has expressly adopted these regulations in order to 
satisfy its statutory obligation to promulgate regulations which are 
necessary to protect human health and the environment in the 
transportation of hazardous waste. EPA's adoption of these DOT 
regulations ensures consistency with the requirements of DOT and thus 
avoids the establishment of duplicative or conflicting requirements with 
respect to these matters. These EPA regulations which apply to both 
interstate and intrastate transportation of hazardous waste are 
enforceable by EPA.
    DOT has revised its hazardous materials transportation regulations 
in order to encompass the transportation of hazardous waste and to 
regulate intrastate, as well as interstate, transportation of hazardous 
waste. Transporters of hazardous waste are cautioned that DOT's 
regulations are fully applicable to their activities and enforceable by 
DOT. These DOT regulations are codified in title 49, Code of Federal 
Regulations, subchapter C.
    EPA and DOT worked together to develop standards for transporters of 
hazardous waste in order to avoid conflicting requirements. Except for 
transporters of bulk shipments of hazardous waste by water, a 
transporter who meets all applicable requirements of 49 CFR parts 171 
through 179 and the requirements of 40 CFR 263.11 and 263.31 will be 
deemed in compliance with this part. Regardless of DOT's action, EPA 
retains its authority to enforce these regulations.

    (b) These regulations do not apply to on-site transportation of 
hazardous waste by generators or by owners or operators of permitted 
hazardous waste management facilities.
    (c) A transporter of hazardous waste must also comply with 40 CFR 
part 262, Standards Applicable to Generators of Hazardous Waste, if he:
    (1) Transports hazardous waste into the United States from abroad;

Sec. 263.20  The manifest system.

    (a) A transporter may not accept hazardous waste from a generator 
unless it is accompanied by a manifest signed in accordance with the 
provisions of 40 CFR 262.20. In the case of exports other than those 
subject to subpart H of 40 CFR part 262, a transporter may not accept 
such waste from a primary exporter or other person if he knows the 
shipment does not conform to the EPA Acknowledgement of Consent; and 
unless, in addition to a manifest signed in accordance with the 
provisions of 40 CFR 262.20, such waste is also accompanied by an EPA 
Acknowledgement of Consent which, except for shipment by rail, is 
attached to the manifest (or shipping paper for exports by water (bulk 
shipment)). For exports of hazardous waste subject to the requirements 
of subpart H of 40 CFR part 262, a transporter may not accept hazardous 
waste without a tracking document that includes all information required 
by 40 CFR 262.84.
    (b) Before transporting the hazardous waste, the transporter must 
sign and date the manifest acknowledging acceptance of the hazardous 
waste from the generator. The transporter must return a signed copy to 
the generator before leaving the generator's property.
    (c) The transporter must ensure that the manifest accompanies the 
hazardous waste. In the case of exports, the transporter must ensure 
that a copy of the EPA Acknowledgment of Consent also accompanies the 
hazardous waste.
    (d) A transporter who delivers a hazardous waste to another 
transporter or to the designated facility must:
    (1) Obtain the date of delivery and the handwritten signature of 
that transporter or of the owner or operator of the designated facility 
on the manifest; and
    (2) Retain one copy of the manifest in accordance with Sec. 263.22; 
and
    (3) Give the remaining copies of the manifest to the accepting 
transporter or designated facility.

designated facility; and
    (2) A shipping paper containing all the information required on the 
manifest (excluding the EPA identification numbers, generator 
certification, and signatures) and, for exports, an EPA Acknowledgment 
of Consent accompanies the hazardous waste; and

[[Page 150]]

    (3) The delivering transporter obtains the date of delivery and 
handwritten signature of the owner or operator of the designated 
facility on either the manifest or the shipping paper; and
    (4) The person delivering the hazardous waste to the initial water 
(bulk shipment) transporter obtains the date of delivery and signature 
of the water (bulk shipment) transporter on the manifest and forwards it 
to the designated facility; and
    (5) A copy of the shipping paper or manifest is retained by each 
water (bulk shipment) transporter in accordance with Sec. 263.22.
    (f) For shipments involving rail transportation, the requirements of 
paragraphs (c), (d) and (e) do not apply and the following requirements 
do apply:
    (1) When accepting hazardous waste from a non-rail transporter, the 
initial rail transporter must:
    (i) Sign and date the manifest acknowledging acceptance of the 
hazardous waste;
    (ii) Return a signed copy of the manifest to the non-rail 
transporter;
    (iii) Forward at least three copies of the manifest to:
    (A) The next non-rail transporter, if any; or,
    (B) The designated facility, if the shipment is delivered to that 
facility by rail; or
    (C) The last rail transporter designated to handle the waste in the 
United States;
    (iv) Retain one copy of the manifest and rail shipping paper in 
accordance with Sec. 263.22.
    (2) Rail transporters must ensure that a shipping paper containing 
all the information required on the manifest (excluding the EPA 
identification numbers, generator certification, and signatures) and, 
for exports an EPA Acknowledgment of Consent accompanies the hazardous 
waste at all times.

    Note: Intermediate rail transporters are not required to sign either 
the manifest or shipping paper.

    (3) When delivering hazardous waste to the designated facility, a 
rail transporter must:
    (i) Obtain the date of delivery and handwritten signature of the 
owner or operator of the designated facility on the manifest or the 
shipping paper (if the manifest has not been received by the facility); 
and
    (ii) Retain a copy of the manifest or signed shipping paper in 
accordance with Sec. 263.22.
    (4) When delivering hazardous waste to a non-rail transporter a rail 
transporter must:
    (i) Obtain the date of delivery and the handwritten signature of the 
next non-rail transporter on the manifest; and
    (ii) Retain a copy of the manifest in accordance with Sec. 263.22.
    (5) Before accepting hazardous waste from a rail transporter, a non-
rail transporter must sign and date the manifest and provide a copy to 
the rail transporter.

Sec. 263.22(c); and
    (3) Return a signed copy of the manifest to the generator; and
    (4) Give a copy of the manifest to a U.S. Customs official at the 
point of departure from the United States.
    (h) A transporter transporting hazardous waste from a generator who 
generates greater than 100 kilograms but less than 1000 kilograms of 
hazardous waste in a calendar month need not comply with the 
requirements of this section or those of Sec. 263.22 provided that:
    (1) The waste is being transported pursuant to a reclamation 
agreement as provided for in Sec. 262.20(e);
    (2) The transporter records, on a log or shipping paper, the 
following information for each shipment:
    (i) The name, address, and U.S. EPA Identification Number of the 
generator of the waste;
    (ii) The quantity of waste accepted;
    (iii) All DOT-required shipping information;
    (iv) The date the waste is accepted; and
    (3) The transporter carries this record when transporting waste to 
the reclamation facility; and

[[Page 151]]

    (4) The transporter retains these records for a period of at least 
three years after termination or expiration of the agreement.

waste which he has accepted from a generator or a transporter to:
    (1) The designated facility listed on the manifest; or
    (2) The alternate designated facility, if the hazardous waste cannot 
be delivered to the designated facility because an emergency prevents 
delivery; or
    (3) The next designated transporter; or
    (4) The place outside the United States designated by the generator.
    (b) If the hazardous waste cannot be delivered in accordance with 
paragraph (a) of this section, the transporter must contact the 
generator for further directions and must revise the manifest according 
to the generator's instructions.



Sec. 263.22  Recordkeeping.

    (a) A transporter of hazardous waste must keep a copy of the 
manifest signed by the generator, himself, and the next designated 
transporter or the owner or operator of the designated facility for a 
period of three years from the date the hazardous waste was accepted by 
the initial transporter.
    (b) For shipments delivered to the designated facility by water 
(bulk shipment), each water (bulk shipment) transporter must retain a 
copy of the shipping paper containing all the information required in 
Sec. 263.20(e)(2) for a period of three years from the date the 
hazardous waste was accepted by the initial transporter.

[45 FR 33221, May 19, 1980, as amended at 50 FR 4514, Jan. 31, 1985]



Sec. 264.12  Required notices.

    (a)(1) The owner or operator of a facility that has arranged to 
receive hazardous waste from a foreign source must notify the Regional 
Administrator in writing at least four weeks in advance of the date the 
waste is expected to arrive at the facility. Notice of subsequent 
shipments of the same waste from the same foreign source is not 
required.
    (2) The owner or operator of a recovery facility that has arranged 
to receive hazardous waste subject to 40 CFR part 262, subpart H must 
provide a copy of the tracking document bearing all required signatures 
to the notifier, to the Office of Enforcement and Compliance Assurance, 
Office of Compliance, Enforcement Planning, Targeting and Data Division 
(2222A), Environmental Protection Agency, 401 M St., SW., Washington, DC 
20460; and to the competent authorities of all other concerned countries 
within three working days of receipt of the shipment. The original of

least three years.
    (b) The owner or operator of a facility that receives hazardous 
waste from an off-site source (except where the

[[Page 158]]

owner or operator is also the generator) must inform the generator in 
writing that he has the appropriate permit(s) for, and will accept, the 
waste the generator is shipping. The owner or operator must keep a copy 
of this written notice as part of the operating record.
    (c) Before transferring ownership or operation of a facility during 
its operating life, or of a disposal facility during the post-closure 
care period, the owner or operator must notify the new owner or operator 
in writing of the requirements of this part and part 270 of this 
chapter.

[Comment: An owner's or operator's failure to notify the new owner or 
operator of the requirements of this part in no way relieves the new 
owner or operator of his obligation to comply with all applicable 
requirements.]

FR 4514, Jan. 31, 1985; 61 FR 16315, Apr. 12, 1996]



Sec. 264.13  General waste analysis.

    (a)(1) Before an owner or operator treats, stores, or disposes of 
any hazardous wastes, or nonhazardous wastes if applicable under 
Sec. 264.113(d), he must obtain a detailed chemical and physical 
analysis of a representative sample of the wastes. At a minimum, the 
analysis must contain all the information which must be known to treat, 
store, or dispose of the waste in accordance with this part and part 268 
of this chapter.
    (2) The analysis may include data developed under part 261 of this 
chapter, and existing published or documented data on the hazardous 
waste or on hazardous waste generated from similar processes.

    [Comment: For example, the facility's records of analyses performed 
on the waste before the effective date of these regulations, or studies 
conducted on hazardous waste generated from processes similar to that 
which generated the waste to be managed at the facility, may be included 
in the data base required to comply with paragraph (a)(1) of this 
section. The owner or operator of an off-site facility may arrange for 
the generator of the hazardous waste to supply part of the information 
required by paragraph (a)(1) of this section, except as otherwise 
specified in 40 CFR 268.7 (b) and (c). If the generator does not supply 
the information, and the owner or operator chooses to accept a hazardous 
waste, the owner or operator is responsible for obtaining the 
information required to comply with this section.]

    (3) The analysis must be repeated as necessary to ensure that it is 
accurate and up to date. At a minimum, the analysis must be repeated:
    (i) When the owner or operator is notified, or has reason to 
believe, that the process or operation generating the hazardous wastes, 
or non-hazardous wastes if applicable under Sec. 264.113(d), has 
changed; and
    (ii) For off-site facilities, when the results of the inspection 
required in paragraph (a)(4) of this section indicate that the hazardous 
waste received at the facility does not match the waste designated on 
the accompanying manifest or shipping paper.
    (4) The owner or operator of an off-site facility must inspect and, 
if necessary, analyze each hazardous waste movement received at the 
facility to determine whether it matches the identity of the waste 
specified on the accompanying manifest or shipping paper.
    (b) The owner or operator must develop and follow a written waste 
analysis plan which describes the procedures which he will carry out to 
comply with paragraph (a) of this section. He must keep this plan at the 
facility. At a minimum, the plan must specify:
    (1) The parameters for which each hazardous waste, or non-hazardous 
waste if applicable under Sec. 264.113(d), will be analyzed and the 
rationale for the selection of these parameters (i.e., how analysis for 
these parameters will provide sufficient information on the waste's 
properties to comply with paragraph (a) of this section);
    (2) The test methods which will be used to test for these 
parameters;
    (3) The sampling method which will be used to obtain a 
representative sample of the waste to be analyzed. A representative 
sample may be obtained using either:
    (i) One of the sampling methods described in appendix I of part 261 
of this chapter; or
    (ii) An equivalent sampling method.

[Comment: See Sec. 260.21 of this chapter for related discussion.]


[[Page 159]]


    (4) The frequency with which the initial analysis of the waste will 
be reviewed or repeated to ensure that the analysis is accurate and up 
to date; and
    (5) For off-site facilities, the waste analyses that hazardous waste 
generators have agreed to supply.
    (6) Where applicable, the methods that will be used to meet the 
additional waste analysis requirements for specific waste management 
methods as specified in Secs. 264.17, 264.314, 264.341, 264.1034(d), 
264.1063(d), 264.1083, and 268.7 of this chapter.
    (7) For surface impoundments exempted from land disposal 
restrictions under Sec. 268.4(a), the procedures and schedules for:
    (i) The sampling of impoundment contents;
    (ii) The analysis of test data; and,
    (iii) The annual removal of residues which are not delisted under 
Sec. 260.22 of this chapter or which exhibit a characteristic of 
hazardous waste and either:
    (A) Do not meet applicable treatment standards of part 268, subpart 
D; or
    (B) Where no treatment standards have been established;
    (1) Such residues are prohibited from land disposal under 
Sec. 268.32 or RCRA section 3004(d); or
    (2) Such residues are prohibited from land disposal under 
Sec. 268.33(f).
    (8) For owners and operators seeking an exemption to the air 
emission standards of subpart CC in accordance with Sec. 264.1082--
    (i) If direct measurement is used for the waste determination, the 
procedures and schedules for waste sampling and analysis, and the 
results of the analysis of test data to verify the exemption.
    (ii) If knowledge of the waste is used for the waste determination, 
any information prepared by the facility owner or operator or by the 
generator of the hazardous waste, if the waste is received from off-
site, that is used as the basis for knowledge of the waste.
    (c) For off-site facilities, the waste analysis plan required in 
paragraph (b) of this section must also specify the procedures which 
will be used to in-spect and, if necessary, analyze each movement of 
hazardous waste received at the facility to ensure that it matches the 
identity of the waste designated on the accompanying manifest or 
shipping paper. At a minimum, the plan must describe:
    (1) The procedures which will be used to determine the identity of 
each movement of waste managed at the facility; and
    (2) The sampling method which will be used to obtain a 
representative sample of the waste to be identified, if the 
identification method includes sampling.
    (3) The procedures that the owner or operator of an off-site 
landfill receiving containerized hazardous waste will use to determine 
whether a hazardous waste generator or treater has added a biodegradable 
sorbent to the waste in the container.

[Comment: Part 270 of this chapter requires that the waste analysis plan 
be submitted with part B of the permit application.]

Sec. 264.14  Security.

    (a) The owner or operator must prevent the unknowing entry, and 
minimize the possibility for the unauthorized entry, of persons or 
livestock onto the active portion of his facility, unless he can 
demonstrate to the Regional Administrator that:
    (1) Physical contact with the waste, structures, or equipment within 
the active portion of the facility will not injure unknowing or 
unauthorized persons or livestock which may enter the active portion of 
a facility; and
    (2) Disturbance of the waste or equipment, by the unknowing or 
unauthorized entry of persons or livestock onto the active portion of a 
facility, will not cause a violation of the requirements of this part.

[Comment: Part 270 of this chapter requires that an owner or operator 
who wishes to make the demonstration referred to above must do so with 
part B of the permit application.]

    (b) Unless the owner or operator has made a successful demonstration 
under

[[Page 160]]

paragraphs (a) (1) and (2) of this section, a facility must have:
    (1) A 24-hour surveillance system (e.g., television monitoring or 
surveillance by guards or facility personnel) which continuously 
monitors and controls entry onto the active portion of the facility; or
    (2)(i) An artificial or natural barrier (e.g., a fence in good 
repair or a fence combined with a cliff), which completely surrounds the 
active portion of the facility; and
    (ii) A means to control entry, at all times, through the gates or 
other entrances to the active portion of the facility (e.g., an 
attendant, television monitors, locked entrance, or controlled roadway 
access to the facility).

[Comment: The requirements of paragraph (b) of this section are 
satisfied if the facility or plant within which the active portion is 
located itself has a surveillance system, or a barrier and a means to 
control entry, which complies with the requirements of paragraph (b) (1) 
or (2) of this section.]

    (c) Unless the owner or operator has made a successful demonstration 
under paragraphs (a) (1) and (2) of this section, a sign with the 
legend, ``Danger--Unauthorized Personnel Keep Out'', must be posted at 
each entrance to the active portion of a facility, and at other 
locations, in sufficient numbers to be seen from any approach to this 
active portion. The legend must be written in English and in any other 
language predominant in the area surrounding the facility (e.g., 
facilities in counties bordering the Canadian province of Quebec must 
post signs in French; facilities in counties bordering Mexico must post 
signs in Spanish), and must be legible from a distance of at least 25 
feet. Existing signs with a legend other than ``Danger--Unauthorized 
Personnel Keep Out'' may be used if the legend on the sign indicates 
that only authorized personnel are allowed to enter the active portion, 
and that entry onto the active portion can be dangerous.

[Comment: See Sec. 264.117(b) for discussion of security requirements at 
disposal facilities during the post-closure care period.]

FR 14294, Apr. 1, 1983; 50 FR 4514, Jan. 31, 1985]



Sec. 264.15  General inspection requirements.

    (a) The owner or operator must inspect his facility for malfunctions 
and deterioration, operator errors, and discharges which may be 
causing--or may lead to--(1) release of hazardous waste constituents to 
the environment or (2) a threat to human health. The owner or operator 
must conduct these inspections often enough to identify problems in time 
to correct them before they harm human health or the environment.
    (b)(1) The owner or operator must develop and follow a written 
schedule for inspecting monitoring equipment, safety and emergency 
equipment, security devices, and operating and structural equipment 
(such as dikes and sump pumps) that are important to preventing, 
detecting, or responding to environmental or human health hazards.
    (2) He must keep this schedule at the facility.
    (3) The schedule must identify the types of problems (e.g., 
malfunctions or deterioration) which are to be looked for during the 
inspection (e.g., inoperative sump pump, leaking fitting, eroding dike, 
etc.).
    (4) The frequency of inspection may vary for the items on the 
schedule. However, it should be based on the rate of deterioration of 
the equipment and the probability of an environmental or human health 
incident if the deterioration, malfunction, or any operator error goes 
undetected between inspections. Areas subject to spills, such as loading 
and unloading areas, must be inspected daily when in use. At a minimum, 
the inspection schedule must include the items and frequencies called 
for in Secs. 264.174, 264.193, 264.195, 264.226, 264.254, 264.278, 
264.303, 264.347, 264.602, 264.1033, 264.1052, 264.1053, 264.1058, 
264.1088, and 264.1091(b), where applicable.

[Comment: Part 270 of this chapter requires the inspection schedule to 
be submitted with part B of the permit application. EPA will evaluate 
the schedule along with the rest of the application to ensure that it

FR 14294, Apr. 1, 1983; 50 FR 4514, Jan. 31, 1985]



Sec. 264.17  General requirements for ignitable, reactive, or incompatible wastes.

    (a) The owner or operator must take precautions to prevent 
accidental ignition or reaction of ignitable or reactive waste. This 
waste must be separated and protected from sources of ignition or 
reaction including but not limited to: open flames, smoking, cutting and 
welding, hot surfaces, frictional heat, sparks (static, electrical, or 
mechanical), spontaneous ignition (e.g., from heat-producing chemical 
reactions), and radiant heat. While ignitable or reactive waste is being 
handled, the owner or operator must confine smoking and open flame to 
specially designated locations. ``No Smoking'' signs must be 
conspicuously placed wherever there is a hazard from ignitable or 
reactive waste.
    (b) Where specifically required by other sections of this part, the 
owner or operator of a facility that treats, stores or disposes 
ignitable or reactive waste, or mixes incompatible waste or incompatible 
wastes and other materials, must take precautions to prevent reactons 
which:
    (1) Generate extreme heat or pressure, fire or explosions, or 
violent reactions;
    (2) Produce uncontrolled toxic mists, fumes, dusts, or gases in 
sufficient quantities to threaten human health or the environment;
    (3) Produce uncontrolled flammable fumes or gases in sufficient 
quantities to pose a risk of fire or explosions;
    (4) Damage the structural integrity of the device or facility;
    (5) Through other like means threaten human health or the 
environment.
    (c) When required to comply with paragraph (a) or (b) of this 
section, the owner or operator must document that compliance. This 
documentation may be based on references to published scientific or 
engineering literature, data from trial tests (e.g., bench scale or 
pilot scale tests), waste analyses (as specified in Sec. 264.13), or the 
results of the treatment of similar wastes by similar treatment 
processes and under similar operating conditions.

[46 FR 2848, Jan. 12, 1981, as amended at 50 FR 4514, Jan. 31, 1985]



Sec. 264.18  Location standards.

    (a) Seismic considerations. (1) Portions of new facilities where 
treatment, storage, or disposal of hazardous waste will be conducted 
must not be located within 61 meters (200 feet) of a fault which has had 
displacement in Holocene time.
    (2) As used in paragraph (a)(1) of this section:
    (i) ``Fault'' means a fracture along which rocks on one side have 
been displaced with respect to those on the other side.
    (ii) ``Displacement'' means the relative movement of any two sides 
of a fault measured in any direction.
    (iii) ``Holocene'' means the most recent epoch of the Quarternary 
period, extending from the end of the Pleistocene to the present.

[Comment: Procedures for demonstrating compliance with this standard in 
part B of the permit application are specified in Sec. 270.14(b)(11). 
Facilities which are located in political jurisdictions other than those 
listed in appendix VI of this part, are assumed to be in compliance with 
this requirement.]

    (b) Floodplains. (1) A facility located in a 100-year floodplain 
must be designed, constructed, operated, and maintained to prevent 
washout or any hazardous waste by a 100-year flood, unless the owner or 
operator can demonstrate to the Regional Administrator's satisfaction 
that:
    (i) Procedures are in effect which will cause the waste to be 
removed safely, before flood waters can reach the facility, to a 
location where the wastes will not be vulnerable to flood waters; or
    (ii) For existing surface impoundments, waste piles, land treatment 
units, landfills, and miscellaneous units, no adverse effects on human 
health or the environment will result if washout occurs, considering:
    (A) The volume and physical and chemical characteristics of the 
waste in the facility;

[[Page 163]]

    (B) The concentration of hazardous constituents that would 
potentially affect surface waters as a result of washout;
    (C) The impact of such concentrations on the current or potential 
uses of and water quality standards established for the affected surface 
waters; and
    (D) The impact of hazardous constituents on the sediments of 
affected surface waters or the soils of the 100- year floodplain that 
could result from washout.

[Comment: The location where wastes are moved must be a facility which 
is either permitted by EPA under part 270 of this chapter, authorized to 
manage hazardous waste by a State with a hazardous waste management 
program authorized under part 271 of this chapter, or in interim status 
under parts 270 and 265 of this chapter.]

    (2) As used in paragraph (b)(1) of this section:
    (i) ``100-year floodplain'' means any land area which is subject to 
a one percent or greater chance of flooding in any given year from any 
source.
    (ii) ``Washout'' means the movement of hazardous waste from the 
active portion of the facility as a result of flooding.
    (iii) ``100-year flood'' means a flood that has a one percent chance 
of being equalled or exeeded in any given year.

[Comment: (1) Requirements pertaining to other Federal laws which affect 
the location and permitting of facilities are found in Sec. 270.3 of 
this chapter. For details relative to these laws, see EPA's manual for 
SEA (special environmental area) requirements for hazardous waste 
facility permits. Though EPA is responsible for complying with these 
requirements, applicants are advised to consider them in planning the 
location of a facility to help prevent subsequent project delays.]

    (c) Salt dome formations, salt bed formations, underground mines and 
caves. The placement of any noncontainerized or bulk liquid hazardous 
waste in any salt dome formation, salt bed formation, underground mine 
or cave is prohibited, except for the Department of Energy Waste 
Isolation Pilot Project in New Mexico.

    (v) Leachate collection and removal systems and leak detection 
systems; and
    (vi) Final cover systems.
    (b) Written CQA plan. The owner or operator of units subject to the 
CQA program under paragraph (a) of this section must develop and 
implement a written CQA plan. The plan must identify steps that will be 
used to monitor and document the quality of materials and the condition 
and manner of their installation. The CQA plan must include:
    (1) Identification of applicable units, and a description of how 
they will be constructed.
    (2) Identification of key personnel in the development and 
implementation of the CQA plan, and CQA officer qualifications.
    (3) A description of inspection and sampling activities for all unit 
components identified in paragraph (a)(2) of this section, including 
observations and tests that will be used before, during, and after 
construction to ensure that the construction materials and

[[Page 164]]

the installed unit components meet the design specifications. The 
description must cover: Sampling size and locations; frequency of 
testing; data evaluation procedures; acceptance and rejection criteria 
for construction materials; plans for implementing corrective measures; 
and data or other information to be recorded and retained in the 
operating record under Sec. 264.73.
    (c) Contents of program. (1) The CQA program must include 
observations, inspections, tests, and measurements sufficient to ensure:
    (i) Structural stability and integrity of all components of the unit 
identified in paragraph (a)(2) of this section;
    (ii) Proper construction of all components of the liners, leachate 
collection and removal system, leak detection system, and final cover 
system, according to permit specifications and good engineering 
practices, and proper installation of all components (e.g., pipes) 
according to design specifications;
    (iii) Conformity of all materials used with design and other 
material specifications under Secs. 264.221, 264.251, and 264.301.
    (2) The CQA program shall include test fills for compacted soil 
liners, using the same compaction methods as in the full scale unit, to 
ensure that the liners are constructed to meet the hydraulic 
conductivity requirements of Secs. 264.221(c)(1)(i)(B), 
264.251(c)(1)(i)(B), and 264.301(c)(1)(i)(B) in the field. Compliance 
with the hydraulic conductivity requirements must be verified by using 
in-situ testing on the constructed test fill. The Regional Administrator 
may accept an alternative demonstration, in lieu of a test fill, where 
data are sufficient to show that a constructed soil liner will meet the 
hydraulic conductivity requirements of Secs. 264.221(c)(1)(i)(B), 
264.251(c)(1)(i)(B), and 264.301(c)(1)(i)(B) in the field.
    (d) Certification. Waste shall not be received in a unit subject to 
Sec. 264.19 until the owner or operator has submitted to the Regional 
Administrator by certified mail or hand delivery a certification signed 
by the CQA officer that the approved CQA plan has been successfully 
carried out and that the unit meets the requirements of Secs. 264.221 
(c) or (d), 264.251 (c) or (d), or 264.301 (c) or (d); and the procedure 
in Sec. 270.30(l)(2)(ii) of this chapter has been completed.

Sec. 264.55  Emergency coordinator.

    At all times, there must be at least one employee either on the 
facility premises or on call (i.e., available to respond to an emergency 
by reaching the facility within a short period of time) with the 
responsibility for coordinating all emergency response measures. This 
emergency coordinator must be thoroughly familiar with all aspects of 
the facility's contingency plan, all operations and activities at the 
facility, the location and characteristics of waste handled, the 
location of all records within the facility, and the facility layout. In 
addition, this person must have the authority to commit the resources 
needed to carry out the contingency plan.

[Comment: The emergency coordinator's responsibilities are more fully 
spelled out in Sec. 264.56. Applicable responsibilities for the 
emergency coordinator vary, depending on factors such as type and 
variety of waste(s) handled by the facility, and type and complexity of 
the facility.]



Sec. 264.56  Emergency procedures.

    (a) Whenever there is an imminent or actual emergency situation, the 
emergency coordinator (or his designee when the emergency coordinator is 
on call) must immediately:
    (1) Activate internal facility alarms or communication systems, 
where applicable, to notify all facility personnel; and
    (2) Notify appropriate State or local agencies with designated 
response roles if their help is needed.
    (b) Whenever there is a release, fire, or explosion, the emergency 
coordinator must immediately identify the character, exact source, 
amount, and areal extent of any released materials. He may do this by 
observation or review of facility records or manifests, and, if 
necessary, by chemical analysis.
    (c) Concurrently, the emergency coordinator must assess possible 
hazards to human health or the environment that may result from the 
release, fire, or explosion. This assessment must consider both direct 
and indirect effects of the release, fire, or explosion (e.g., the 
effects of any toxic, irritating, or asphyxiating gases that are 
generated, or the effects of any hazardous surface water run-off from 
water or chemical agents used to control fire and heat-induced 
explosions).
    (d) If the emergency coordinator determines that the facility has 
had a release, fire, or explosion which could threaten human health, or 
the environment, outside the facility, he must report his findings as 
follows:
    (1) If his assessment indicates that evacuation of local areas may 
be advisable, he must immediately notify appropriate local authorities. 
He must be available to help appropriate officials decide whether local 
areas should be evacuated; and
    (2) He must immediately notify either the government official 
designated as the on-scene coordinator for that geographical area, (in 
the applicable regional contingency plan under part 1510 of this title) 
or the National Response Center (using their 24-hour toll free number 
800/424-8802). The report must include:
    (i) Name and telephone number of reporter;
    (ii) Name and address of facility;
    (iii) Time and type of incident (e.g., release, fire);
    (iv) Name and quantity of material(s) involved, to the extent known;
    (v) The extent of injuries, if any; and
    (vi) The possible hazards to human health, or the environment, 
outside the facility.

[[Page 168]]

    (e) During an emergency, the emergency coordinator must take all 
reasonable measures necessary to ensure that fires, explosions, and 
releases do not occur, recur, or spread to other hazardous waste at the 
facility. These measures must include, where applicable, stopping 
processes and operations, collecting and containing release waste, and 
removing or isolating containers.
    (f) If the facility stops operations in response to a fire, 
explosion, or release, the emergency coordinator must monitor for leaks, 
pressure buildup, gas generation, or ruptures in valves, pipes, or other 
equipment, wherever this is appropriate.
    (g) Immediately after an emergency, the emergency coordinator must 
provide for treating, storing, or disposing of recovered waste, 
contaminated soil or surface water, or any other material that results 
from a release, fire, or explosion at the facility.

[Comment: Unless the owner or operator can demonstrate, in accordance 
with Sec. 261.3(c) or (d) of this chapter, that the recovered material 
is not a hazardous waste, the owner or operator becomes a generator of 
hazardous waste and must manage it in accordance with all applicable 
requirements of parts 262, 263, and 264 of this chapter.]

    (h) The emergency coordinator must ensure that, in the affected 
area(s) of the facility:
    (1) No waste that may be incompatible with the released material is 
treated, stored, or disposed of until cleanup procedures are completed; 
and
    (2) All emergency equipment listed in the contingency plan is 
cleaned and fit for its intended use before operations are resumed.
    (i) The owner or operator must notify the Regional Administrator, 
and appropriate State and local authorities, that the facility is in 
compliance with paragraph (h) of this section before operations are 
resumed in the affected area(s) of the facility.
    (j) The owner or operator must note in the operating record the 
time, date, and details of any incident that requires implementing the 
contingency plan. Within 15 days after the incident, he must submit a 
written report on the incident to the Regional Administrator. The report 
must include:
    (1) Name, address, and telephone number of the owner or operator;
    (2) Name, address, and telephone number of the facility;
    (3) Date, time, and type of incident (e.g., fire, explosion);
    (4) Name and quantity of material(s) involved;
    (5) The extent of injuries, if any;
    (6) An assessment of actual or potential hazards to human health or 
the environment, where this is applicable; and
    (7) Estimated quantity and disposition of recovered material that 
resulted from the incident.

Sec. 264.71  Use of manifest system.

    (a) If a facility receives hazardous waste accompanied by a 
manifest, the owner or operator, or his agent, must:
    (1) Sign and date each copy of the manifest to certify that the 
hazardous waste covered by the manifest was received;
    (2) Note any significant discrepancies in the manifest (as defined 
in Sec. 264.72(a)) on each copy of the manifest;

[Comment: The Agency does not intend that the owner or operator of a 
facility whose procedures under Sec. 264.13(c) include waste analysis 
must perform that analysis before signing the manifest and giving it to 
the transporter. Section 264.72(b), however, requires reporting an 
unreconciled discrepancy discovered during later analysis.]

    (3) Immediately give the transporter at least one copy of the signed 
manifest;
    (4) Within 30 days after the delivery, send a copy of the manifest 
to the generator; and
    (5) Retain at the facility a copy of each manifest for at least 
three years from the date of delivery.
    (b) If a facility receives, from a rail or water (bulk shipment) 
transporter, hazardous waste which is accompanied by a shipping paper 
containing all the information required on the manifest (excluding the 
EPA identification numbers, generator's certification, and signatures), 
the owner or operator, or his agent, must:
    (1) Sign and date each copy of the manifest or shipping paper (if 
the manifest has not been received) to certify that the hazardous waste 
covered by the manifest or shipping paper was received;
    (2) Note any significant discrepancies (as defined in 
Sec. 264.72(a)) in the manifest or shipping paper (if the manifest has 
not been received) on each copy of the manifest or shipping paper.

[Comment: The Agency does not intend that the owner or operator of a 
facility whose procedures under Sec. 264.13(c) include waste analysis 
must perform that analysis before signing the shipping paper and giving 
it to the transporter. Section 264.72(b), however, requires reporting an 
unreconciled discrepancy discovered during later analysis.]

    (3) Immediately give the rail or water (bulk shipment) transporter 
at least one copy of the manifest or shipping paper (if the manifest has 
not been received);
    (4) Within 30 days after the delivery, send a copy of the signed and 
dated manifest to the generator; however, if the manifest has not been 
received within 30 days after delivery, the owner or operator, or his 
agent, must send a copy of the shipping paper signed and dated to the 
generator; and

[Comment: Section 262.23(c) of this chapter requires the generator to 
send three copies of the manifest to the facility when hazardous waste 
is sent by rail or water (bulk shipment).]

    (5) Retain at the facility a copy of the manifest and shipping paper 
(if signed in lieu of the manifest at the time of delivery) for at least 
three years from the date of delivery.
    (c) Whenever a shipment of hazardous waste is initiated from a 
facility, the owner or operator of that facility must comply with the 
requirements of part 262 of this chapter.

[Comment: The provisions of Sec. 262.34 are applicable to the on-site 
accumulation of hazardous wastes by generators. Therefore, the 
provisions of Sec. 262.34 only apply to owners or operators who are 
shipping hazardous waste which they generated at that facility.]
    (d) Within three working days of the receipt of a shipment subject 
to 40 CFR part 262, subpart H, the owner or operator of the facility 
must provide a copy of the tracking document bearing all required 
signatures to the notifier, to the Office of Enforcement and Compliance 
Assurance, Office of Compliance, Enforcement Planning, Targeting and 
Data Division (2222A), Environmental Protection Agency, 401 M St., SW., 
Washington, DC 20460, and to competent authorities of all other 
concerned countries. The original copy of the tracking document must be 
maintained at the facility for at least three years from the date of 
signature.

1980; 61 FR 16315, Apr. 12, 1996]



Sec. 264.72  Manifest discrepancies.

    (a) Manifest discrepancies are differences between the quantity or 
type of hazardous waste designated on the manifest or shipping paper, 
and the quantity or type of hazardous waste a

[[Page 170]]

facility actually receives. Significant discrepancies in quantity are:
    (1) For bulk waste, variations greater than 10 percent in weight, 
and (2) for batch waste, any variation in piece count, such as a 
discrepancy of one drum in a truckload. Significant discrepancies in 
type are obvious differences which can be discovered by inspection or 
waste analysis, such as waste solvent substituted for waste acid, or 
toxic constituents not reported on the manifest or shipping paper.
    (b) Upon discovering a significant discrepancy, the owner or 
operator must attempt to reconcile the discrepancy with the waste 
generator or transporter (e.g., with telephone conversations). If the 
discrepancy is not resolved within 15 days after receiving the waste, 
the owner or operator must immediately submit to the Regional 
Administrator a letter describing the discrepancy and attempts to 
reconcile it, and a copy of the manifest or shipping paper at issue.

[45 FR 33221, May 19, 1980, as amended at 50 FR 4514, Jan. 31, 1985]



Sec. 264.73  Operating record.

    (a) The owner or operator must keep a written operating record at 
his facility.
    (b) The following information must be recorded, as it becomes 
available, and maintained in the operating record until closure of the 
facility:
    (1) A description and the quantity of each hazardous waste received, 
and the method(s) and date(s) of its treatment, storage, or disposal at 
the facility as required by appendix I;
    (2) The location of each hazardous waste within the facility and the 
quantity at each location. For disposal facilities, the location and 
quantity of each hazardous waste must be recorded on a map or diagram of 
each cell or disposal area. For all facilities, this information must 
include cross-references to specific manifest document numbers, if the 
waste was accompanied by a manifest;

[Comment: See Sec. 264.119 for related requirements.]

    (3) Records and results of waste analyses and waste determinations

Sec. 264.75  Biennial report.

    The owner or operator must prepare and submit a single copy of a 
biennial report to the Regional Administrator by March 1 of each even 
numbered year. The biennial report must be submitted on EPA form 8700-
13B. The report must cover facility activities during the previous 
calendar year and must include:
    (a) The EPA identification number, name, and address of the 
facility;
    (b) The calendar year covered by the report;
    (c) For off-site facilities, the EPA identification number of each 
hazardous waste generator from which the facility received a hazardous 
waste during the year; for imported shipments, the report must give the 
name and address of the foreign generator;
    (d) A description and the quantity of each hazardous waste the 
facility received during the year. For off-site facilities, this 
information must be listed by EPA identification number of each 
generator;
    (e) The method of treatment, storage, or disposal for each hazardous 
waste;
    (f) [Reserved]

Sec. 264.76  Unmanifested waste report.

    If a facility accepts for treatment, storage, or disposal any 
hazardous waste from an off-site source without

[[Page 172]]

an accompanying manifest, or without an accompanying shipping paper as 
described in Sec. 263.20(e)(2) of this chapter, and if the waste is not 
excluded from the manifest requirement by Sec. 261.5 of this chapter, 
then the owner or operator must prepare and submit a single copy of a 
report to the Regional Administrator within fifteen days after receiving 
the waste. The unmanifested waste report must be submitted on EPA form 
8700-13B. Such report must be designated `Unmanifested Waste Report' and 
include the following information:
    (a) The EPA identification number, name, and address of the 
facility;
    (b) The date the facility received the waste;
    (c) The EPA identification number, name, and address of the 
generator and the transporter, if available;
    (d) A description and the quantity of each unmanifested hazardous 
waste and facility received;
    (e) The method of treatment, storage, or disposal for each hazardous 
waste;
    (f) The certification signed by the owner or operator of the 
facility or his authorized representative; and
    (g) A brief explanation of why the waste was unmanifested, if known.

[Comment: Small quantities of hazardous waste are excluded from 
regulation under this part and do not require a manifest. Where a 
facility receives unmanifested hazardous wastes, the Agency suggests 
that the owner or operator obtain from each generator a certification 
that the waste qualifies for exclusion. Otherwise, the Agency suggests 
that the owner or operator file an unmanifested waste report for the 
hazardous waste movement.]

          Subpart F--Releases From Solid Waste Management Units

    Source: 47 FR 32350, July 26, 1982, unless otherwise noted.



Sec. 264.90  Applicability.

    (a)(1) Except as provided in paragraph (b) of this section, the 
regulations in this subpart apply to owners or operators of facilities 
that treat, store or dispose of hazardous waste. The owner or operator 
must satisfy the requirements identified in paragraph (a)(2) of this 
section for all wastes (or constituents thereof) contained in solid 
waste management units at the facility, regardless of the time at which 
waste was placed in such units.
    (2) All solid waste management units must comply with the 
requirements in Sec. 264.101. A surface impoundment, waste pile, and 
land treatment unit or landfill that receives hazardous waste after July 
26, 1982 (hereinafter referred to as a ``regulated unit'') must comply 
with the requirements of Secs. 264.91 through 264.100 in lieu of 
Sec. 264.101 for purposes of detecting, characterizing and responding to 
releases to the uppermost aquifer. The financial responsibility 
requirements of Sec. 264.101 apply to regulated units.
    (b) The owner or operator's regulated unit or units are not subject 
to regulation for releases into the uppermost aquifer under this subpart 
if:
    (1) The owner or operator is exempted under Sec. 264.1; or
    (2) He operates a unit which the Regional Administrator finds:
    (i) Is an engineered structure,
    (ii) Does not receive or contain liquid waste or waste containing 
free liquids,
    (iii) Is designed and operated to exclude liquid, precipitation, and 
other run-on and run-off,
    (iv) Has both inner and outer layers of containment enclosing the 
waste,
    (v) Has a leak detection system built into each containment layer,

[[Page 173]]

    (vi) The owner or operator will provide continuing operation and 
maintenance of these leak detection systems during the active life of 
the unit and the closure and post-closure care periods, and
    (vii) To a reasonable degree of certainty, will not allow hazardous 
constituents to migrate beyond the outer containment layer prior to the 
end of the post-closure care period.
    (3) The Regional Administrator finds, pursuant to Sec. 264.280(d), 
that the treatment zone of a land treatment unit that qualifies as a 
regulated unit does not contain levels of hazardous constituents that 
are above background levels of those constituents by an amount that is 
statistically significant, and if an unsaturated zone monitoring program 
meeting the requirements of Sec. 264.278 has not shown a statistically 
significant increase in hazardous constituents below the treatment zone 
during the operating life of the unit. An exemption under this paragraph 
can only relieve an owner or operator of responsibility to meet the 
requirements of this subpart during the post-closure care period; or
    (4) The Regional Administrator finds that there is no potential for 
migration of liquid from a regulated unit to the uppermost aquifer 
during the active life of the regulated unit (including the closure 
period) and the post-closure care period specified under Sec. 264.117. 
This demonstration must be certified by a qualified geologist or 
geotechnical engineer. In order to provide an adequate margin of safety 
in the prediction of potential migration of liquid, the owner or 
operator must base any predictions made under this paragraph on 
assumptions that maximize the rate of liquid migration.
    (5) He designs and operates a pile in compliance with 
Sec. 264.250(c).
    (c) The regulations under this subpart apply during the active life 
of the regulated unit (including the closure period). After closure of 
the regulated unit, the regulations in this subpart:
    (1) Do not apply if all waste, waste residues, contaminated 
containment system components, and contaminated subsoils are removed or 
decontaminated at closure;
    (2) Apply during the post-closure care period under Sec. 264.117 if 
the owner or operator is conducting a detection monitoring program under 
Sec. 264.98; or
    (3) Apply during the compliance period under Sec. 264.96 if the 
owner or operator is conducting a compliance monitoring program under 
Sec. 264.99 or a corrective action program under Sec. 264.100.
    (d) Regulations in this subpart may apply to miscellaneous units 
when necessary to comply with Secs. 264.601 through 264.603.

[47 FR 32350, July 26, 1982, as amended at 50 FR 28746, July 15, 1985; 
52 FR 46963, Dec. 10, 1987]



Sec. 264.91  Required programs.

    (a) Owners and operators subject to this subpart must conduct a 
monitoring and response program as follows:
    (1) Whenever hazardous constituents under Sec. 264.93 from a 
regulated unit are detected at a compliance point under Sec. 264.95, the 
owner or operator must institute a compliance monitoring program under 
Sec. 264.99. Detected is defined as statistically significant evidence 
of contamination as described in Sec. 264.98(f);
    (2) Whenever the ground-water protection standard under Sec. 264.92 
is exceeded, the owner or operator must institute a corrective action 
program under Sec. 264.100. Exceeded is defined as statistically 
significant evidence of increased contamination as described in 
Sec. 264.99(d);
    (3) Whenever hazardous constituents under Sec. 264.93 from a 
regulated unit exceed concentration limits under Sec. 264.94 in ground 
water between the compliance point under Sec. 264.95 and the 
downgradient facility property boundary, the owner or operator must 
institute a corrective action program under Sec. 264.100; or
    (4) In all other cases, the owner or operator must institute a 
detection monitoring program under Sec. 264.98.
    (b) The Regional Administrator will specify in the facility permit 
the specific elements of the monitoring and response program. The 
Regional Administrator may include one or more of the programs 
identified in paragraph (a) of this section in the facility permit as 
may be necessary to protect human health and the environment and will

[[Page 174]]

specify the circumstances under which each of the programs will be 
required. In deciding whether to require the owner or operator to be 
prepared to institute a particular program, the Regional Administrator 
will consider the potential adverse effects on human health and the 
environment that might occur before final administrative action on a 
permit modification application to incorporate such a program could be 
taken.

[47 FR 32350, July 26, 1982, as amended at 53 FR 39728, Oct. 11, 1988]



Sec. 264.92  Ground-water protection standard.

    The owner or operator must comply with conditions specified in the 
facility permit that are designed to ensure that hazardous constituents 
under Sec. 264.93 detected in the ground water from a regulated unit do 
not exceed the concentration limits under Sec. 264.94 in the uppermost 
aquifer underlying the waste management area beyond the point of 
compliance under Sec. 264.95 during the compliance period under 
Sec. 264.96. The Regional Administrator will establish this ground-water 
protection standard in the facility permit when hazardous constituents 
have been detected in the ground water.

[53 FR 39728, Oct. 11, 1988]



Sec. 264.93  Hazardous constituents.

    (a) The Regional Administrator will specify in the facility permit 
the hazardous constituents to which the ground-water protection standard 
of Sec. 264.92 applies. Hazardous constituents are constituents 
identified in appendix VIII of part 261 of this chapter that have been 
detected in ground water in the uppermost aquifer underlying a regulated 
unit and that are reasonably expected to be in or derived from waste 
contained in a regulated unit, unless the Regional Administrator has 
excluded them under paragraph (b) of this section.
    (b) The Regional Administrator will exclude an appendix VIII 
constituent from the list of hazardous constituents specified in the 
facility permit if he finds that the constituent is not capable of 
posing a substantial present or potential hazard to human health or the 
environment. In deciding whether to grant an exemption, the Regional 
Administrator will consider the following:
    (1) Potential adverse effects on ground-water quality, considering:
    (i) The physical and chemical characteristics of the waste in the 
regulated unit, including its potential for migration;
    (ii) The hydrogeological characteristics of the facility and 
surrounding land;
    (iii) The quantity of ground water and the direction of ground-water 
flow;
    (iv) The proximity and withdrawal rates of ground-water users;
    (v) The current and future uses of ground water in the area;
    (vi) The existing quality of ground water, including other sources 
of contamination and their cumulative impact on the ground-water 
quality;
    (vii) The potential for health risks caused by human exposure to 
waste constituents;
    (viii) The potential damage to wildlife, crops, vegetation, and 
physical structures caused by exposure to waste constituents;
    (ix) The persistence and permanence of the potential adverse 
effects; and
    (2) Potential adverse effects on hydraulically-connected surface 
water quality, considering:
    (i) The volume and physical and chemical characteristics of the 
waste in the regulated unit;
    (ii) The hydrogeological characteristics of the facility and 
surrounding land;
    (iii) The quantity and quality of ground water, and the direction of 
ground-water flow;
    (iv) The patterns of rainfall in the region;
    (v) The proximity of the regulated unit to surface waters;
    (vi) The current and future uses of surface waters in the area and 
any water quality standards established for those surface waters;
    (vii) The existing quality of surface water, including other sources 
of contamination and the cumulative impact on surface-water quality;
    (viii) The potential for health risks caused by human exposure to 
waste constituents;

[[Page 175]]

    (ix) The potential damage to wildlife, crops, vegetation, and 
physical structures caused by exposure to waste constituents; and
    (x) The persistence and permanence of the potential adverse effects.
    (c) In making any determination under paragraph (b) of this section 
about the use of ground water in the area around the facility, the 
Regional Administrator will consider any identification of underground 
sources of drinking water and exempted aquifers made under Sec. 144.8 of 
this chapter.

Sec. 264.94  Concentration limits.

    (a) The Regional Administrator will specify in the facility permit 
concentration limits in the ground water for hazardous constituents 
established under Sec. 264.93. The concentration of a hazardous 
constituent:
    (1) Must not exceed the background level of that constituent in the 
ground water at the time that limit is specified in the permit; or
    (2) For any of the constituents listed in Table 1, must not exceed 
the respective value given in that table if the background level of the 
constituent is below the value given in Table 1; or

    (3) Must not exceed an alternate limit established by the Regional 
Administrator under paragraph (b) of this section.
    (b) The Regional Administrator will establish an alternate 
concentration limit for a hazardous constituent if he finds that the 
constituent will not pose a substantial present or potential hazard to 
human health or the environment as long as the alternate concentration 
limit is not exceeded. In establishing alternate concentration limits, 
the Regional Administrator will consider the following factors:
    (1) Potential adverse effects on ground-water quality, considering:
    (i) The physical and chemical characteristics of the waste in the 
regulated unit, including its potential for migration;
    (ii) The hydrogeological characteristics of the facility and 
surrounding land;
    (iii) The quantity of ground water and the direction of ground-water 
flow;
    (iv) The proximity and withdrawal rates of ground-water users;
    (v) The current and future uses of ground water in the area;
    (vi) The existing quality of ground water, including other sources 
of contamination and their cumulative impact on the ground-water 
quality;
    (vii) The potential for health risks caused by human exposure to 
waste constituents;
    (viii) The potential damage to wildlife, crops, vegetation, and 
physical structures caused by exposure to waste constituents;
    (ix) The persistence and permanence of the potential adverse 
effects; and
    (2) Potential adverse effects on hydraulically-connected surface-
water quality, considering:
    (i) The volume and physical and chemical characteristics of the 
waste in the regulated unit;
    (ii) The hydrogeological characteristics of the facility and 
surrounding land;
    (iii) The quantity and quality of ground water, and the direction of 
ground-water flow;
    (iv) The patterns of rainfall in the region;
    (v) The proximity of the regulated unit to surface waters;

[[Page 176]]

    (vi) The current and future uses of surface waters in the area and 
any water quality standards established for those surface waters;
    (vii) The existing quality of surface water, including other sources 
of contamination and the cumulative impact on surface water quality;
    (viii) The potential for health risks caused by human exposure to 
waste constituents;
    (ix) The potential damage to wildlife, crops, vegetation, and 
physical structures caused by exposure to waste constituents; and
    (x) The persistence and permanence of the potential adverse effects.
    (c) In making any determination under paragraph (b) of this section 
about the use of ground water in the area around the facility the 
Regional Administrator will consider any identification of underground

this chapter.

[47 FR 32350, July 26, 1982, as amended at 48 FR 14294, Apr. 1, 1983]



Sec. 264.95  Point of compliance.

    (a) The Regional Administrator will specify in the facility permit 
the point of compliance at which the ground-water protection standard of 
Sec. 264.92 applies and at which monitoring must be conducted. The point 
of compliance is a vertical surface located at the hydraulically 
downgradient limit of the waste management area that extends down into 
the uppermost aquifer underlying the regulated units.
    (b) The waste management area is the limit projected in the 
horizontal plane of the area on which waste will be placed during the 
active life of a regulated unit.
    (1) The waste management area includes horizontal space taken up by 
any liner, dike, or other barrier designed to contain waste in a 
regulated unit.
    (2) If the facility contains more than one regulated unit, the waste 
management area is described by an imaginary line circumscribing the 
several regulated units.



Sec. 264.96  Compliance period.

    (a) The Regional Administrator will specify in the facility permit 
the compliance period during which the ground-water protection standard 
of Sec. 264.92 applies. The compliance period is the number of years 
equal to the active life of the waste management area (including any 
waste management activity prior to permitting, and the closure period.)
    (b) The compliance period begins when the owner or operator 
initiates a compliance monitoring program meeting the requirements of 
Sec. 264.99.
    (c) If the owner or operator is engaged in a corrective action 
program at the end of the compliance period specified in paragraph (a) 
of this section, the compliance period is extended until the owner or 
operator can demonstrate that the ground-water protection standard of 
Sec. 264.92 has not been exceeded for a period of three consecutive 
years.



Sec. 264.97  General ground-water monitoring requirements.

    The owner or operator must comply with the following requirements 
for any ground-water monitoring program developed to satisfy 
Sec. 264.98, Sec. 264.99, or Sec. 264.100:
    (a) The ground-water monitoring system must consist of a sufficient 
number of wells, installed at appropriate locations and depths to yield 
ground-water samples from the uppermost aquifer that:
    (1) Represent the quality of background water that has not been 
affected by leakage from a regulated unit;
    (i) A determination of background quality may include sampling of 
wells that are not hydraulically upgradient of the waste management area 
where:
    (A) Hydrogeologic conditions do not allow the owner or operator to 
determine what wells are hydraulically upgradient; and
    (B) Sampling at other wells will provide an indication of background 
ground-water quality that is representative or more representative than 
that provided by the upgradient wells; and
    (2) Represent the quality of ground water passing the point of 
compliance.
    (3) Allow for the detection of contamination when hazardous waste or 
hazardous constituents have migrated

[[Page 177]]

from the waste management area to the uppermost aquifer.
    (b) If a facility contains more than one regulated unit, separate 
ground-water monitoring systems are not required for each regulated unit 
provided that provisions for sampling the ground water in the uppermost 
aquifer will enable detection and measurement at the compliance point of 
hazardous constituents from the regulated units that have entered the 
ground water in the uppermost aquifer.
    (c) All monitoring wells must be cased in a manner that maintains 
the integrity of the monitoring-well bore hole. This casing must be 
screened or perforated and packed with gravel or sand, where necessary, 
to enable collection of ground-water samples. The annular space (i.e., 
the space between the bore hole and well casing) above the sampling 
depth must be sealed to prevent contamination of samples and the ground 
water.
    (d) The ground-water monitoring program must include consistent 
sampling and analysis procedures that are designed to ensure monitoring 
results that provide a reliable indication of ground-water quality below 
the waste management area. At a minimum the program must include 
procedures and techniques for:
    (1) Sample collection;
    (2) Sample preservation and shipment;
    (3) Analytical procedures; and
    (4) Chain of custody control.
    (e) The ground-water monitoring program must include sampling and 
analytical methods that are appropriate for ground-water sampling and 
that accurately measure hazardous constituents in ground-water samples.
    (f) The ground-water monitoring program must include a determination 
of the ground-water surface elevation each time ground water is sampled.
    (g) In detection monitoring or where appropriate in compliance 
monitoring, data on each hazardous constituent specified in the permit 
will be collected from background wells and wells at the compliance 
point(s). The number and kinds of samples collected to establish 
background shall be appropriate for the form of statistical test 
employed, following generally accepted statistical principles. The 
sample size shall be as large as necessary to ensure with reasonable 
confidence that a contaminant release to ground water from a facility 
will be detected. The owner or operator will determine an appropriate 
sampling procedure and interval for each hazardous constituent listed in 
the facility permit which shall be specified in the unit permit upon 
approval by the Regional Administrator. This sampling procedure shall 
be:
    (1) A sequence of at least four samples, taken at an interval that 
assures, to the greatest extent technically feasible, that an 
independent sample is obtained, by reference to the uppermost aquifer's 
effective porosity, hydraulic conductivity, and hydraulic gradient, and 
the fate and transport characteristics of the potential contaminants, or
    (2) an alternate sampling procedure proposed by the owner or 
operator and approved by the Regional Administrator.
    (h) The owner or operator will specify one of the following 
statistical methods to be used in evaluating ground-water monitoring 
data for each hazardous constituent which, upon approval by the Regional 
Administrator, will be specified in the unit permit. The statistical 
test chosen shall be conducted separately for each hazardous constituent 
in each well. Where practical quantification limits (pql's) are used in 
any of the following statistical procedures to comply with 
Sec. 264.97(i)(5), the pql must be proposed by the owner or operator and 
approved by the Regional Administrator. Use of any of the following 
statistical methods must be protective of human health and the 
environment and must comply with the performance standards outlined in 
paragraph (i) of this section.
    (1) A parametric analysis of variance (ANOVA) followed by multiple 
comparisons procedures to identify statistically significant evidence of 
contamination. The method must include estimation and testing of the 
contrasts between each compliance well's mean and the background mean 
levels for each constituent.
    (2) An analysis of variance (ANOVA) based on ranks followed by 
multiple

[[Page 178]]

comparisons procedures to identify statistically significant evidence of 
contamination. The method must include estimation and testing of the 
contrasts between each compliance well's median and the background 
median levels for each constituent.
    (3) A tolerance or prediction interval procedure in which an 
interval for each constituent is established from the distribution of 
the background data, and the level of each constituent in each 
compliance well is compared to the upper tolerance or prediction limit.
    (4) A control chart approach that gives control limits for each 
constituent.
    (5) Another statistical test method submitted by the owner or 
operator and approved by the Regional Administrator.
    (i) Any statistical method chosen under Sec. 264.97(h) for 
specification in the unit permit shall comply with the following 
performance standards, as appropriate:
    (1) The statistical method used to evaluate ground-water monitoring 
data shall be appropriate for the distribution of chemical parameters or 
hazardous constituents. If the distribution of the chemical parameters 
or hazardous constituents is shown by the owner or operator to be 
inappropriate for a normal theory test, then the data should be 
transformed or a distribution-free theory test should be used. If the 
distributions for the constituents differ, more than one statistical 
method may be needed.
    (2) If an individual well comparison procedure is used to compare an 
individual compliance well constituent concentration with background 
constituent concentrations or a ground-water protection standard, the 
test shall be done at a Type I error level no less than 0.01 for each 
testing period. If a multiple comparisons procedure is used, the Type I 
experimentwise error rate for each testing period shall be no less than 
0.05; however, the Type I error of no less than 0.01 for individual well 
comparisons must be maintained. This performance standard does not apply 
to tolerance intervals, prediction intervals or control charts.
    (3) If a control chart approach is used to evaluate ground-water 
monitoring data, the specific type of control chart and its associated 
parameter values shall be proposed by the owner or operator and approved 
by the Regional Administrator if he or she finds it to be protective of 
human health and the environment.
    (4) If a tolerance interval or a prediction interval is used to 
evaluate groundwater monitoring data, the levels of confidence and, for 
tolerance intervals, the percentage of the population that the interval 
must contain, shall be proposed by the owner or operator and approved by 
the Regional Administrator if he or she finds these parameters to be 
protective of human health and the environment. These parameters will be 
determined after considering the number of samples in the background 
data base, the data distribution, and the range of the concentration 
values for each constituent of concern.
    (5) The statistical method shall account for data below the limit of 
detection with one or more statistical procedures that are protective of 
human health and the environment. Any practical quantification limit 
(pql) approved by the Regional Administrator under Sec. 264.97(h) that 
is used in the statistical method shall be the lowest concentration 
level tha can be reliably achieved within specified limits of precision 
and accuracy during routine laboratory operating conditions that are 
available to the facility.
    (6) If necessary, the statistical method shall include procedures to 
control or correct for seasonal and spatial variability as well as 
temporal correlation in the data.
    (j) Ground-water monitoring data collected in accordance with 
paragraph (g) of this section including actual levels of constituents 
must be maintained in the facility operating record. The Regional 
Administrator will specify in the permit when the data must be submitted 
for review.

Sec. 264.98  Detection monitoring program.

    An owner or operator required to establish a detection monitoring 
program under this subpart must, at a minimum, discharge the following 
responsibilities:
    (a) The owner or operator must monitor for indicator parameters 
(e.g., specific conductance, total organic carbon, or total organic 
halogen), waste constituents, or reaction products that provide a 
reliable indication of the presence of hazardous constituents in ground 
water. The Regional Administrator will specify the parameters or 
constituents to be monitored in the facility permit, after considering 
the following factors:
    (1) The types, quantities, and concentrations of constituents in 
wastes managed at the regulated unit;
    (2) The mobility, stability, and persistance of waste constituents 
or their reaction products in the unsaturated zone beneath the waste 
management area;
    (3) The detectability of indicator parameters, waste constituents, 
and reaction products in ground water; and
    (4) The concentrations or values and coefficients of variation of 
proposed monitoring parameters or constituents in the ground-water 
background.
    (b) The owner or operator must install a ground-water monitoring 
system at the compliance point as specified under Sec. 264.95. The 
ground-water monitoring system must comply with Sec. 264.97(a)(2), (b), 
and (c).
    (c) The owner or operator must conduct a ground-water monitoring 
program for each chemical parameter and hazardous constituent specified 
in the permit pursuant to paragraph (a) of this section in accordance 
with Sec. 264.97(g). The owner or operator must maintain a record of 
ground-water analytical data as measured and in a form necessary for the 
determination of statistical significance under Sec. 264.97(h).
    (d) The Regional Administrator will specify the frequencies for 
collecting samples and conducting statistical tests to determine whether 
there is statistically significant evidence of contamination for any 
parameter or hazardous constituent specified in the permit under 
paragraph (a) of this section in accordance with Sec. 264.97(g). A 
sequence of at least four samples from each well (background and 
compliance wells) must be collected at least semi-annually during 
detection monitoring.
    (e) The owner or operator must determine the ground-water flow rate 
and direction in the uppermost aquifer at least annually.
    (f) The owner or operator must determine whether there is 
statistically significant evidence of contamination for any chemical 
parameter of hazardous constituent specified in the permit pursuant to 
paragraph (a) of this section at a frequency specified under paragraph 
(d) of this section.
    (1) In determining whether statistically significant evidence of 
contamination exists, the owner or operator must use the method(s) 
specified in the permit under Sec. 264.97(h). These method(s) must 
compare data collected at the compliance point(s) to the background 
ground-water quality data.
    (2) The owner or operator must determine whether there is 
statistically significant evidence of contamination at each monitoring 
well as the compliance point within a reasonable period of time after 
completion of sampling. The Regional Administrator will specify in the 
facility permit what period of time is reasonable, after considering the 
complexity of the statistical test and the availability of laboratory 
facilities to perform the analysis of ground-water samples.
    (g) If the owner or operator determines pursuant to paragraph (f) of 
this section that there is statistically significant evidence of 
contamination for chemical parameters or hazardous constituents 
specified pursuant to paragraph (a) of this section at any monitoring 
well at the compliance point, he or she must:
    (1) Notify the Regional Administrator of this finding in writing 
within seven days. The notification must indicate what chemical 
parameters or hazardous constituents have shown statistically 
significant evidence of contamination;
    (2) Immediately sample the ground water in all monitoring wells and 
determine whether constituents in the list of appendix IX of part 264 
are

[[Page 180]]

present, and if so, in what concentration.
    (3) For any appendix IX compounds found in the analysis pursuant to 
paragraph (g)(2) of this section, the owner or operator may resample 
within one month and repeat the analysis for those compounds detected. 
If the results of the second analysis confirm the initial results, then 
these constituents will form the basis for compliance monitoring. If the 
owner or operator does not resample for the compounds found pursuant to 
paragraph (g)(2) of this section, the hazardous constituents found 
during this initial appendix IX analysis will form the basis for 
compliance monitoring.
    (4) Within 90 days, submit to the Regional Administrator an 
application for a permit modification to establish a compliance 
monitoring program meeting the requirements of Sec. 264.99. The 
application must include the following information:
    (i) An identification of the concentration or any appendix IX 
constituent detected in the ground water at each monitoring well at the 
compliance point;
    (ii) Any proposed changes to the ground-water monitoring system at 
the facility necessary to meet the requirements of Sec. 264.99;
    (iii) Any proposed additions or changes to the monitoring frequency, 
sampling and analysis procedures or methods, or statistical methods used 
at the facility necessary to meet the requirements of Sec. 264.99;
    (iv) For each hazardous constituent detected at the compliance 
point, a proposed concentration limit under Sec. 264.94(a) (1) or (2), 
or a notice of intent to seek an alternate concentration limit under 
Sec. 264.94(b); and
    (5) Within 180 days, submit to the Regional Administrator:
    (i) All data necessary to justify an alternate concentration limit 
sought under Sec. 264.94(b); and
    (ii) An engineering feasibility plan for a corrective action program 
necessary to meet the requirement of Sec. 264.100, unless:
    (A) All hazardous constituents identified under paragraph (g)(2) of 
this section are listed in Table 1 of Sec. 264.94 and their 
concentrations do not exceed the respective values given in that Table; 
or
    (B) The owner or operator has sought an alternate concentration 
limit under Sec. 264.94(b) for every hazardous constituent identified 
under paragraph (g)(2) of this section.
    (6) If the owner or operator determines, pursuant to paragraph (f) 
of this section, that there is a statistically significant difference 
for chemical parameters or hazardous constituents specified pursuant to 
paragraph (a) of this section at any monitoring well at the compliance 
point, he or she may demonstrate that a source other than a regulated 
unit caused the contamination or that the detection is an artifact 
caused by an error in sampling, analysis, or statistical evaluation or 
natural variation in the ground water. The owner operator may make a 
demonstration under this paragraph in addition to, or in lieu of, 
submitting a permit modification application under paragraph (g)(4) of 
this section; however, the owner or operator is not relieved of the 
requirement to submit a permit modification application within the time 
specified in paragraph (g)(4) of this section unless the demonstration 
made under this paragraph successfully shows that a source other than a 
regulated unit caused the increase, or that the increase resulted from 
error in sampling, analysis, or evaluation. In making a demonstration 
under this paragraph, the owner or operator must:
    (i) Notify the Regional Administrator in writing within seven days 
of determining statistically significant evidence of contamination at 
the compliance point that he intends to make a demonstration under this 
paragraph;
    (ii) Within 90 days, submit a report to the Regional Administrator 
which demonstrates that a source other than a regulated unit caused the 
contamination or that the contamination resulted from error in sampling, 
analysis, or evaluation;
    (iii) Within 90 days, submit to the Regional Administrator an 
application for a permit modification to make any appropriate changes to 
the detection monitoring program facility; and
    (iv) Continue to monitor in accordance with the detection monitoring 
program established under this section.

[[Page 181]]

    (h) If the owner or operator determines that the detection 
monitoring program no longer satisfies the requirements of this section, 
he or she must, within 90 days, submit an application for a permit 
modification to make any appropriate changes to the program.

Sec. 264.99  Compliance monitoring program.

    An owner or operator required to establish a compliance monitoring 
program under this subpart must, at a minimum, discharge the following 
responsibilities:
    (a) The owner or operator must monitor the ground water to determine 
whether regulated units are in compliance with the ground-water 
protection standard under Sec. 264.92. The Regional Administrator will 
specify the ground-water protection standard in the facility permit, 
including:
    (1) A list of the hazardous constituents identified under 
Sec. 264.93;
    (2) Concentration limits under Sec. 264.94 for each of those 
hazardous constituents;
    (3) The compliance point under Sec. 264.95; and
    (4) The compliance period under Sec. 264.96.
    (b) The owner or operator must install a ground-water monitoring 
system at the compliance point as specified under Sec. 264.95. The 
ground-water monitoring system must comply with Sec. 264.97(a)(2), (b), 
and (c).
    (c) The Regional Administrator will specify the sampling procedures 
and statistical methods appropriate for the constituents and the 
facility, consistent with Sec. 264.97 (g) and (h).
    (1) The owner or operator must conduct a sampling program for each 
chemical parameter or hazardous constituent in accordance with 
Sec. 264.97(g).
    (2) The owner or operator must record ground-water analytical data 
as measured and in form necessary for the determination of statistical 
significance under Sec. 264.97(h) for the compliance period of the 
facility.
    (d) The owner or operator must determine whether there is 
statistically significant evidence of increased contamination for any 
chemical parameter or hazardous constituent specified in the permit, 
pursuant to paragraph (a) of this section, at a frequency specified 
under paragraph (f) under this section.
    (1) In determining whether statistically significant evidence of 
increased contamination exists, the owner or operator must use the 
method(s) specified in the permit under Sec. 264.97(h). The methods(s) 
must compare data collected at the compliance point(s) to a 
concentration limit developed in accordance with Sec. 264.94.
    (2) The owner or operator must determine whether there is 
statistically significant evidence of increased contamination at each 
monitoring well at the compliance point within a reasonable time period 
after completion of sampling. The Regional Administrator will specify 
that time period in the facility permit, after considering the 
complexity of the statistical test and the availability of laboratory 
facilities to perform the analysis of ground-water samples.
    (e) The owner or operator must determine the ground-water flow rate 
and direction in the uppermost aquifer at least annually.
    (f) The Regional Administrator will specify the frequencies for 
collecting samples and conducting statistical tests to determine 
statistically significant evidence of increased contamination in 
accordance with Sec. 264.97(g). A sequence of at least four samples from 
each well (background and compliance wells) must be collected at least 
semi-annually during the compliance period of the facility.
    (g) The owner or operator must analyze samples from all monitoring 
wells at the compliance point for all constituents contained in appendix 
IX of part 264 at least annually to determine whether additional 
hazardous constituents are present in the uppermost aquifer and, if so, 
at what concentration, pursuant to procedures in Sec. 264.98(f). If the 
owner or operator finds appendix IX constituents in the ground water 
that are not already identified in the permit as monitoring 
constituents, the owner or operator may resample within one month and 
repeat the appendix IX

[[Page 182]]

analysis. If the second analysis confirms the presence of new 
constituents, the owner or operator must report the concentration of 
these additional constituents to the Regional Administrator within seven 
days after the completion of the second analysis and add them to the 
monitoring list. If the owner or operator chooses not to resample, then 
he or she must report the concentrations of these additional 
constituents to the Regional Administrator within seven days after 
completion of the intiial analysis and add them to the monitoring list.
    (h) If the owner or operator determines pursuant to paragraph (d) of 
this section that any concentration limits under Sec. 264.94 are being 
exceeded at any monitoring well at the point of compliance he or she 
must:
    (1) Notify the Regional Administrator of this finding in writing 
within seven days. The notification must indicate what concentration 
limits have been exceeded.
    (2) Submit to the Regional Administrator an application for a permit 
modification to establish a corrective action program meeting the 
requirements of Sec. 264.100 within 180 days, or within 90 days if an 
engineering feasibility study has been previously submitted to the 
Regional Administrator under Sec. 264.98(h)(5). The application must at 
a minimum include the following information:
    (i) A detailed description of corrective actions that will achieve 
compliance with the ground-water protection standard specified in the 
permit under paragraph (a) of this section; and
    (ii) A plan for a ground-water monitoring program that will 
demonstrate the effectiveness of the corrective action. Such a ground-
water monitoring program may be based on a compliance monitoring program 
developed to meet the requirements of this section.
    (i) If the owner or operator determines, pursuant to paragraph (d) 
of this section, that the ground-water concentration limits under this 
section are being exceeded at any monitoring well at the point of 
compliance, he or she may demonstrate that a source other than a 
regulated unit caused the contamination or that the detection is an 
artifact caused by an error in sampling, analysis, or statistical 
evaluation or natural variation in the ground water. In making a 
demonstration under this paragraph, the owner or operator must:
    (1) Notify the Regional Administrator in writing within seven days 
that he intends to make a demonstration under this paragraph;
    (2) Within 90 days, submit a report to the Regional Administrator 
which demonstrates that a source other than a regulated unit caused the 
standard to be exceeded or that the apparent noncompliance with the 
standards resulted from error in sampling, analysis, or evaluation;
    (3) Within 90 days, submit to the Regional Administrator an 
application for a permit modification to make any appropriate changes to 
the compliance monitoring program at the facility; and
    (4) Continue to monitor in accord with the compliance monitoring 
program established under this section.
    (j) If the owner or operator determines that the compliance 
monitoring program no longer satisfies the requirements of this section, 
he must, within 90 days, submit an application for a permit modification 
to make any appropriate changes to the program.

Sec. 264.100  Corrective action program.

    An owner or operator required to establish a corrective action 
program under this subpart must, at a minimum, discharge the following 
responsibilities:
    (a) The owner or operator must take corrective action to ensure that 
regulated units are in compliance with the ground-water protection 
standard under Sec. 264.92. The Regional Administrator will specify the 
ground-water protection standard in the facility permit, including:
    (1) A list of the hazardous constituents identified under 
Sec. 264.93;
    (2) Concentration limits under Sec. 264.94 for each of those 
hazardous constituents;
    (3) The compliance point under Sec. 264.95; and

[[Page 183]]

    (4) The compliance period under Sec. 264.96.
    (b) The owner or operator must implement a corrective action program 
that prevents hazardous constituents from exceeding their respective 
concentration limits at the compliance point by removing the hazardous 
waste constituents or treating them in place. The permit will specify 
the specific measures that will be taken.
    (c) The owner or operator must begin corrective action within a 
reasonable time period after the ground-water protection standard is 
exceeded. The Regional Administrator will specify that time period in 
the facility permit. If a facility permit includes a corrective action 
program in addition to a compliance monitoring program, the permit will 
specify when the corrective action will begin and such a requirement 
will operate in lieu of Sec. 264.99(i)(2).
    (d) In conjunction with a corrective action program, the owner or 
operator must establish and implement a ground-water monitoring program 
to demonstrate the effectiveness of the corrective action program. Such 
a monitoring program may be based on the requirements for a compliance 
monitoring program under Sec. 264.99 and must be as effective as that 
program in determining compliance with the ground-water protection 
standard under Sec. 264.92 and in determining the success of a 
corrective action program under paragraph (e) of this section, where 
appropriate.
    (e) In addition to the other requirements of this section, the owner 
or operator must conduct a corrective action program to remove or treat 
in place any hazardous constituents under Sec. 264.93 that exceed 
concentration limits under Sec. 264.94 in groundwater:
    (1) Between the compliance point under Sec. 264.95 and the 
downgradient property boundary; and
    (2) Beyond the facility boundary, where necessary to protect human 
health and the environment, unless the owner or operator demonstrates to 
the satisfaction of the Regional Administrator that, despite the owner's 
or operator's best efforts, the owner or operator was unable to obtain 
the necessary permission to undertake such action. The owner/operator is 
not relieved of all responsibility to clean up a release that has 
migrated beyond the facility boundary where off-site access is denied. 
On-site measures to address such releases will be determined on a case-
by-case basis.
    (3) Corrective action measures under this paragraph must be 
initiated and completed within a reasonable period of time considering 
the extent of contamination.
    (4) Corrective action measures under this paragraph may be 
terminated once the concentration of hazardous constituents under 
Sec. 264.93 is reduced to levels below their respective concentration 
limits under Sec. 264.94.
    (f) The owner or operator must continue corrective action measures 
during the compliance period to the extent necessary to ensure that the 
ground-water protection standard is not exceeded. If the owner or 
operator is conducting corrective action at the end of the compliance 
period, he must continue that corrective action for as long as necessary 
to achieve compliance with the ground-water protection standard. The 
owner or operator may terminate corrective action measures taken beyond 
the period equal to the active life of the waste management area 
(including the closure period) if he can demonstrate, based on data from 
the ground-water monitoring program under paragraph (d) of this section, 
that the ground-water protection standard of Sec. 264.92 has not been 
exceeded for a period of three consecutive years.
    (g) The owner or operator must report in writing to the Regional 
Administrator on the effectiveness of the corrective action program. The 
owner or operator must submit these reports semi-annually.
    (h) If the owner or operator determines that the corrective action 
program no longer satisfies the requirements of this section, he must, 
within 90 days, submit an application for a permit modification to make 
any appropriate changes to the program.

Sec. 264.101  Corrective action for solid waste management units.

    (a) The owner or operator of a facility seeking a permit for the 
treatment, storage or disposal of hazardous waste must institute 
corrective action as necessary to protect human health and the 
environment for all releases of hazardous waste or constituents from any 
solid waste management unit at the facility, regardless of the time at 
which waste was placed in such unit.
    (b) Corrective action will be specified in the permit in accordance 
with this section and subpart S of this part. The permit will contain 
schedules of compliance for such corrective action (where such 
corrective action cannot be completed prior to issuance of the permit) 
and assurances of financial responsibility for completing such 
corrective action.
    (c) The owner or operator must implement corrective actions beyond 
the facility property boundary, where necessary to protect human health 
and the environment, unless the owner or operator demonstrates to the 
satisfaction of the Regional Administrator that, despite the owner's or 
operator's best efforts, the owner or operator was unable to obtain the 
necessary permission to undertake such actions. The owner/operator is 
not relieved of all responsibility to clean up a release that has 
migrated beyond the facility boundary where off-site access is denied. 
On-site measures to address such releases will be determined on a case-
by-case basis. Assurances of financial responsibility for such 
corrective action must be provided.

Sec. 264.112  Closure plan; amendment of plan.

    (a) Written plan. (1) The owner or operator of a hazardous waste 
management facility must have a written closure plan. In addition, 
certain surface impoundments and waste piles from which the owner or 
operator intends to remove or decontaminate the hazardous waste at 
partial or final closure are required by Secs. 264.228(c)(1)(i) and 
264.258(c)(1)(i) to have contingent closure plans. The plan must be 
submitted

[[Page 185]]

with the permit application, in accordance with Sec. 270.14(b)(13) of 
this chapter, and approved by the Regional Administrator as part of the 
permit issuance procedures under part 124 of this chapter. In accordance 
with Sec. 270.32 of this chapter, the approved closure plan will become 
a condition of any RCRA permit.
    (2) The Director's approval of the plan must ensure that the 
approved closure plan is consistent with Secs. 264.111 through 264.115 
and the applicable requirements of subpart F of this part, 
Secs. 264.178, 264.197, 264.228, 264.258, 264.280, 264.310, 264.351, 
264.601, and 264.1102. Until final closure is completed and certified in 
accordance with Sec. 264.115, a copy of the approved plan and all 
approved revisions must be furnished to the Director upon request, 
including requests by mail.
    (b) Content of plan. The plan must identify steps necessary to 
perform partial and/or final closure of the facility at any point during 
its active life. The closure plan must include, at least:
    (1) A description of how each hazardous waste management unit at the 
facility will be closed in accordance with Sec. 264.111;
    (2) A description of how final closure of the facility will be 
conducted in accordance with Sec. 264.111. The description must identify 
the maximum extent of the operations which will be unclosed during the 
active life of the facility; and
    (3) An estimate of the maximum inventory of hazardous wastes ever 
on-site over the active life of the facility and a detailed description 
of the methods to be used during partial closures and final closure, 
including, but not limited to, methods for removing, transporting, 
treating, storing, or disposing of all hazardous wastes, and 
identification of the type(s) of the off-site hazardous waste management 
units to be used, if applicable; and
    (4) A detailed description of the steps needed to remove or 
decontaminate all hazardous waste residues and contaminated containment 
system components, equipment, structures, and soils during partial and 
final closure, including, but not limited to, procedures for cleaning 
equipment and removing contaminated soils, methods for sampling and 
testing surrounding soils, and criteria for determining the extent of 
decontamination required to satisfy the closure performance standard; 
and
    (5) A detailed description of other activities necessary during the 
closure period to ensure that all partial closures and final closure 
satisfy the closure performance standards, including, but not limited 
to, ground-water monitoring, leachate collection, and run-on and run-off 
control; and
    (6) A schedule for closure of each hazardous waste management unit 
and for final closure of the facility. The schedule must include, at a 
minimum, the total time required to close each hazardous waste 
management unit and the time required for intervening closure activities 
which will allow tracking of the progress of partial and final closure. 
(For example, in the case of a landfill unit, estimates of the time 
required to treat or dispose of all hazardous waste inventory and of the 
time required to place a final cover must be included.)
    (7) For facilities that use trust funds to establish financial 
assurance under Sec. 264.143 or Sec. 264.145 and that are expected to 
close prior to the expiration of the permit, an estimate of the expected 
year of final closure.
    (c) Amendment of plan. The owner or operator must submit a written 
notification of or request for a permit modification to authorize a 
change in operating plans, facility design, or the approved closure plan 
in accordance with the applicable procedures in parts 124 and 270. The 
written notification or request must include a copy of the amended 
closure plan for review or approval by the Regional Administrator.
    (1) The owner or operator may submit a written notification or 
request to the Regional Administrator for a permit modification to amend 
the closure plan at any time prior to the notification of partial or 
final closure of the facility.
    (2) The owner or operator must submit a written notification of or 
request for a permit modification to authorize a change in the approved 
closure plan whenever:
    (i) Changes in operating plans or facility design affect the closure 
plan, or

[[Page 186]]

    (ii) There is a change in the expected year of closure, if 
applicable, or
    (iii) In conducting partial or final closure activities, unexpected 
events require a modification of the approved closure plan.
    (3) The owner or operator must submit a written request for a permit 
modification including a copy of the amended closure plan for approval 
at least 60 days prior to the proposed change in facility design or 
operation, or no later than 60 days after an unexpected event has 
occurred which has affected the closure plan. If an unexpected event 
occurs during the partial or final closure period, the owner or operator 
must request a permit modification no later than 30 days after the 
unexpected event. An owner or operator of a surface impoundment or waste 
pile that intends to remove all hazardous waste at closure and is not 
otherwise required to prepare a contingent closure plan under 
Sec. 264.228(c)(1)(i) or Sec. 264.258(c)(1)(i), must submit an amended 
closure plan to the Regional Administrator no later than 60 days from 
the date that the owner or operator or Regional Administrator determines 
that the hazardous waste management unit must be closed as a landfill, 
subject to the requirements of Sec. 264.310, or no later than 30 days 
from that date if the determination is made during partial or final 
closure. The Regional Administrator will approve, disapprove, or modify 
this amended plan in accordance with the procedures in parts 124 and 
270. In accordance with Sec. 270.32 of this chapter, the approved 
closure plan will become a condition of any RCRA permit issued.
    (4) The Regional Administrator may request modifications to the plan 
under the conditions described in Sec. 264.112(c)(2). The owner or 
operator must submit the modified plan within 60 days of the Regional 
Administrator's request, or within 30 days if the change in facility 
conditions occurs during partial or final closure. Any modifications 
requested by the Regional Administrator will be approved in accordance 
with the procedures in parts 124 and 270.
    (d) Notification of partial closure and final closure. (1) The owner 
or operator must notify the Regional Administrator in writing at least 
60 days prior to the date on which he expects to begin closure of a 
surface impoundment, waste pile, land treatment or landfill unit, or 
final closure of a facility with such a unit. The owner or operator must 
notify the Regional Administrator in writing at least 45 days prior to 
the date on which he expects to begin final closure of a facility with 
only treatment or storage tanks, container storage, or incinerator units 
to be closed. The owner or operator must notify the Regional 
Administrator in writing at least 45 days prior to the date on which he 
expects to begin partial or final closure of a boiler or industrial 
furnace, whichever is earlier.
    (2) The date when he ``expects to begin closure'' must be either:
    (i) No later than 30 days after the date on which any hazardous 
waste management unit receives the known final volume of hazardous 
wastes, or if there is a reasonable possibility that the hazardous waste 
management unit will receive additional hazardous wastes, no later than 
one year after the date on which the unit received the most recent 
volume of hazardous wastes. If the owner or operator of a hazardous 
waste management unit can demonstrate to the Regional Administrator that 
the hazardous waste management unit or facility has the capacity to 
receive additional hazardous wastes and he has taken all steps to 
prevent threats to human health and the environment, including 
compliance with all applicable permit requirements, the Regional 
Administrator may approve an extension to this one-year limit; or
    (ii) For units meeting the requirements of Sec. 264.113(d), no later 
than 30 days after the date on which the hazardous waste management unit 
receives the known final volume of non-hazardous wastes, or if there is 
a reasonable possibility that the hazardous waste management unit will 
receive additional non-hazardous wastes, no later than one year after 
the date on which the unit received the most recent volume of non-
hazardous wastes. If the owner or operator can demonstrate to the 
Regional Administrator that the hazardous waste management

[[Page 187]]

unit has the capacity to receive additional non-hazardous wastes and he 
has taken, and will continue to take, all steps to prevent threats to 
human health and the environment, including compliance with all 
applicable permit requirements, the Regional Administrator may approve 
an extension to this one-year limit.
    (3) If the facility's permit is terminated, or if the facility is 
otherwise ordered, by judicial decree or final order under section 3008 
of RCRA, to cease receiving hazardous wastes or to close, then the 
requirements of this paragraph do not apply. However, the owner or 
operator must close the facility in accordance with the deadlines 
established in Sec. 264.113.
    (e) Removal of wastes and decontamination or dismantling of 
equipment. Nothing in this section shall preclude the owner or operator 
from removing hazardous wastes and decontaminating or dismantling 
equipment in accordance with the approved partial or final closure plan 
at any time before or after notification of partial or final closure.

financial assurance for closure and post-closure care as necessary and 
appropriate, to reflect any changes due to the presence of hazardous 
constituents in the non-hazardous wastes, and changes in closure 
activities, including the expected year of closure if applicable under 
Sec. 264.112(b)(7), as a result of the receipt of non-hazardous wastes 
following the final receipt of hazardous wastes; and
    (3) The request to modify the permit includes revisions, as 
necessary and appropriate, to affected conditions of the permit to 
account for the receipt of non-hazardous wastes following receipt of the 
final volume of hazardous wastes; and
    (4) The request to modify the permit and the demonstrations referred 
to in paragraphs (d)(1) and (d)(2) of this section are submitted to the 
Regional Administrator no later than 120 days prior to the date on which 
the owner or operator of the facility receives the known final volume of 
hazardous wastes at the unit, or no later than 90 days after the 
effective date of this rule in the state in which the unit is located, 
whichever is later.
    (e) In addition to the requirements in paragraph (d) of this 
section, an owner or operator of a hazardous waste surface impoundment 
that is not in compliance with the liner and leachate collection system 
requirements in 42 U.S.C. 3004(o)(1) and 3005(j)(1) or 42 U.S.C. 3004(o) 
(2) or (3) or 3005(j) (2), (3), (4) or (13) must:
    (1) Submit with the request to modify the permit:
    (i) A contingent corrective measures plan, unless a corrective 
action plan has already been submitted under Sec. 264.99; and
    (ii) A plan for removing hazardous wastes in compliance with 
paragraph (e)(2) of this section; and
    (2) Remove all hazardous wastes from the unit by removing all 
hazardous liquids, and removing all hazardous sludges to the extent 
practicable without impairing the integrity of the liner(s), if any.
    (3) Removal of hazardous wastes must be completed no later than 90

[[Page 189]]

days after the final receipt of hazardous wastes. The Regional 
Administrator may approve an extension to this deadline if the owner or 
operator demonstrates that the removal of hazardous wastes will, of 
necessity, take longer than the allotted period to complete and that an 
extension will not pose a threat to human health and the environment.
    (4) If a release that is a statistically significant increase (or 
decrease in the case of pH) over background values for detection 
monitoring parameters or constituents specified in the permit or that 
exceeds the facility's ground-water protection standard at the point of 
compliance, if applicable, is detected in accordance with the 
requirements in subpart F of this part, the owner or operator of the 
unit:
    (i) Must implement corrective measures in accordance with the 
approved contingent corrective measures plan required by paragraph 
(e)(1) of this section no later than one year after detection of the 
release, or approval of the contingent corrective measures plan, 
whichever is later;
    (ii) May continue to receive wastes at the unit following detection 
of the release only if the approved corrective measures plan includes a 
demonstration that continued receipt of wastes will not impede 
corrective action; and
    (iii) May be required by the Regional Administrator to implement 
corrective measures in less than one year or to cease the receipt of 
wastes until corrective measures have been implemented if necessary to 
protect human health and the environment.
    (5) During the period of corrective action, the owner or operator 
shall provide semi-annual reports to the Regional Administrator that 
describe the progress of the corrective action program, compile all 
ground-water monitoring data, and evaluate the effect of the continued 
receipt of non-hazardous wastes on the effectiveness of the corrective 
action.
    (6) The Regional Administrator may require the owner or operator to 
commence closure of the unit if the owner or operator fails to implement 
corrective action measures in accordance with the approved contingent 
corrective measures plan within one year as required in paragraph (e)(4) 
of this section, or fails to make substantial progress in implementing 
corrective action and achieving the facility's ground-water protection 
standard or background levels if the facility has not yet established a 
ground-water protection standard.
    (7) If the owner or operator fails to implement corrective measures 
as required in paragraph (e)(4) of this section, or if the Regional 
Administrator determines that substantial progress has not been made 
pursuant to paragraph (e)(6) of this section he shall:
    (i) Notify the owner or operator in writing that the owner or 
operator must begin closure in accordance with the deadlines in 
paragraphs (a) and (b) of this section and provide a detailed statement 
of reasons for this determination, and
    (ii) Provide the owner or operator and the public, through a 
newspaper notice, the opportunity to submit written comments on the 
decision no later than 20 days after the date of the notice.
    (iii) If the Regional Administrator receives no written comments, 
the decision will become final five days after the close of the comment 
period. The Regional Administrator will notify the owner or operator 
that the decision is final, and that a revised closure plan, if 
necessary, must be submitted within 15 days of the final notice and that 
closure must begin in accordance with the deadlines in paragraphs (a) 
and (b) of this section.
    (iv) If the Regional Administrator receives written comments on the 
decision, he shall make a final decision within 30 days after the end of 
the comment period, and provide the owner or operator in writing and the 
public through a newspaper notice, a detailed statement of reasons for 
the final decision. If the Regional Administrator determines that 
substantial progress has not been made, closure must be initiated in 
accordance with the deadlines in paragraphs (a) and (b) of this section.
    (v) The final determinations made by the Regional Administrator 
under paragraphs (e)(7) (iii) and (iv) of this

[[Page 190]]

section are not subject to administrative appeal.

Sec. 264.114  Disposal or decontamination of equipment, structures and soils.

    During the partial and final closure periods, all contaminated 
equipment, structures and soils must be properly disposed of or 
decontaminated unless otherwise specified in Secs. 264.197, 264.228, 
264.258, 264.280 or Sec. 264.310. By removing any hazardous wastes or 
hazardous constituents during partial and final closure, the owner or 
operator may become a generator of hazardous waste and must handle that 
waste in accordance with all applicable requirements of part 262 of this 
chapter.

[51 FR 16444, May 2, 1986, as amended at 52 FR 46963, Dec. 10, 1987; 53 
FR 34086, Sept. 2, 1988]



Sec. 264.115  Certification of closure.

    Within 60 days of completion of closure of each hazardous waste 
surface impoundment, waste pile, land treatment, and landfill unit, and 
within 60 days of the completion of final closure, the owner or operator 
must submit to the Regional Administrator, by registered mail, a 
certification that the hazardous waste management unit or facility, as 
applicable, has been closed in accordance with the specifications in the 
approved closure plan. The certification must be signed by the owner or 
operator and by an independent registered professional engineer. 
Documentation supporting the independent registered professional 
engineer's certification must be furnished to the Regional Administrator 
upon request until he releases the owner or operator from the financial 
assurance requirements for closure under Sec. 264.143(i).



Sec. 264.116  Survey plat.

    No later than the submission of the certification of closure of each 
hazardous waste disposal unit, the owner or operator must submit to the 
local zoning authority, or the authority with jurisdiction over local 
land use, and to the Regional Administrator, a survey plat indicating 
the location and dimensions of landfills cells or other hazardous waste 
disposal units with respect to permanently surveyed benchmarks. This 
plat must be prepared and certified by a professional land surveyor. The 
plat filed with the local zoning authority, or the authority with 
jurisdiction over local land use, must contain a note, prominently 
displayed, which states the owner's or operator's obligation to restrict 
disturbance of the hazardous waste disposal unit in accordance with the 
applicable subpart G regulations.



Sec. 264.117  Post-closure care and use of property.

    (a)(1) Post-closure care for each hazardous waste management unit 
subject to the requirements of Secs. 264.117 through 264.120 must begin 
after completion of closure of the unit and continue for 30 years after 
that date and must consist of at least the following:
    (i) Monitoring and reporting in accordance with the requirements of 
subparts F, K, L, M, N, and X of this part; and
    (ii) Maintenance and monitoring of waste containment systems in 
accordance with the requirements of subparts F, K, L, M, N, and X of 
this part.
    (2) Any time preceding partial closure of a hazardous waste 
management unit subject to post-closure care requirements or final 
closure, or any time during the post-closure period for a particular 
unit, the Regional Administrator may, in accordance with the permit 
modification procedures in parts 124 and 270:
    (i) Shorten the post-closure care period applicable to the hazardous 
waste management unit, or facility, if all disposal units have been 
closed, if he finds that the reduced period is sufficient to protect 
human health and the environment (e.g., leachate or ground-water 
monitoring results, characteristics of the hazardous wastes, application 
of advanced technology, or alternative disposal, treatment, or re-use 
techniques indicate that the hazardous waste management unit or facility 
is secure); or
    (ii) Extend the post-closure care period applicable to the hazardous 
waste management unit or facility if he finds that the extended period 
is necessary

[[Page 191]]

to protect human health and the environment (e.g., leachate or ground-
water monitoring results indicate a potential for migration of hazardous 
wastes at levels which may be harmful to human health and the 
environment).
    (b) The Regional Administrator may require, at partial and final 
closure, continuation of any of the security requirements of Sec. 264.14 
during part or all of the post-closure period when:
    (1) Hazardous wastes may remain exposed after completion of partial 
or final closure; or
    (2) Access by the public or domestic livestock may pose a hazard to 
human health.
    (c) Post-closure use of property on or in which hazardous wastes 
remain after partial or final closure must never be allowed to disturb 
the integrity of the final cover, liner(s), or any other components of 
the containment system, or the function of the facility's monitoring 
systems, unless the Regional Administrator finds that the disturbance:
    (1) Is necessary to the proposed use of the property, and will not 
increase the potential hazard to human health or the environment; or
    (2) Is necessary to reduce a threat to human health or the 
environment.
    (d) All post-closure care activities must be in accordance with the 
provisions of the approved post-closure plan as specified in 
Sec. 264.118.

[51 FR 16444, May 2, 1986, as amended at 52 FR 46963, Dec. 10, 1987]



Sec. 264.118  Post-closure plan; amendment of plan.

    (a) Written Plan. The owner or operator of a hazardous waste 
disposal unit must have a written post-closure plan. In addition, 
certain surface impoundments and waste piles from which the owner or 
operator intends to remove or decontaminate the hazardous wastes at 
partial or final closure are required by Secs. 264.228(c)(1)(ii) and 
264.258(c)(1)(ii) to have contingent post-closure plans. Owners or 
operators of surface impoundments and waste piles not otherwise required 
to prepare contingent post-closure plans under Secs. 264.228(c)(1)(ii) 
and 264.258(c)(1)(ii) must submit a post-closure plan to the Regional 
Administrator within 90 days from the date that the owner or operator or 
Regional administrator determines that the hazardous waste management 
unit must be closed as a landfill, subject to the requirements of 
Secs. 264.117 through 264.120. The plan must be submitted with the 
permit application, in accordance with Sec. 270.14(b)(13) of this 
chapter, and approved by the Regional Administrator as part of the 
permit issuance procedures under part 124 of this chapter. In accordance 
with Sec. 270.32 of this chapter, the approved post-closure plan will 
become a condition of any RCRA permit issued.
    (b) For each hazardous waste management unit subject to the 
requirements of this section, the post-closure plan must identify the 
activities that will be carried on after closure of each disposal unit 
and the frequency of these activities, and include at least:
    (1) A description of the planned monitoring activities and 
frequencies at which they will be performed to comply with subparts F, 
K, L, M, N, and X of this part during the post-closure care period; and
    (2) A description of the planned maintenance activities, and 
frequencies at which they will be performed, to ensure:
    (i) The integrity of the cap and final cover or other containment 
systems in accordance with the requirements of subparts F, K, L, M, N, 
and X of this part; and
    (ii) The function of the monitoring equipment in accordance with the 
requirements of subparts, F, K, L, M, N, and X of this part; and
    (3) The name, address, and phone number of the person or office to 
contact about the hazardous waste disposal unit or facility during the 
post-closure care period.
    (c) Until final closure of the facility, a copy of the approved 
post-closure plan must be furnished to the Regional Administrator upon 
request, including request by mail. After final closure has been 
certified, the person or office specified in Sec. 264.188(b)(3) must 
keep the approved post-closure plan during the remainder of the post-
closure period.
    (d) Amendment of plan. The owner or operator must submit a written 
notification of or request for a permit modification to authorize a 
change in the

[[Page 192]]

approved post-closure plan in accordance with the applicable 
requirements in parts 124 and 270. The written notification or request 
must include a copy of the amended post-closure plan for review or 
approval by the Regional Administrator.
    (1) The owner or operator may submit a written notification or 
request to the Regional Administrator for a permit modification to amend 
the post-closure plan at any time during the active life of the facility 
or during the post-closure care period.
    (2) The owner or operator must submit a written notification of or 
request for a permit modification to authorize a change in the approved 
post-closure plan whenever:
    (i) Changes in operating plans or facility design affect the 
approved post-closure plan, or
    (ii) There is a change in the expected year of final closure, if 
applicable, or
    (iii) Events which occur during the active life of the facility, 
including partial and final closures, affect the approved post-closure 
plan.
    (3) The owner or operator must submit a written request for a permit 
modification at least 60 days prior to the proposed change in facility 
design or operation, or no later than 60 days after an unexpected event 
has occurred which has affected the post-closure plan. An owner or 
operator of a surface impoundment or waste pile that intends to remove 
all hazardous waste at closure and is not otherwise required to submit a 
contingent post-closure plan under Secs. 264.228(c)(1)(ii) and 
264.258(c)(1)(ii) must submit a post-closure plan to the Regional 
Administrator no later than 90 days after the date that the owner or 
operator or Regional Administrator determines that the hazardous waste 
management unit must be closed as a landfill, subject to the 
requirements of Sec. 264.310. The Regional Administrator will approve, 
disapprove or modify this plan in accordance with the procedures in 
parts 124 and 270. In accordance with Sec. 270.32 of this chapter, the 
approved post-closure plan will become a permit condition.
    (4) The Regional Administrator may request modifications to the plan 
under the conditions described in Sec. 264.118(d)(2). The owner or 
operator must submit the modified plan no later than 60 days after the 
Regional Administrator's request, or no later than 90 days if the unit 
is a surface impoundment or waste pile not previously required to 
prepare a contingent post-closure plan. Any modifications requested by 
the Regional Administrator will be approved, disapproved, or modified in 
accordance with the procedures in parts 124 and 270.

FR 37935, Sept. 28,1988]



Sec. 264.119  Post-closure notices.

    (a) No later than 60 days after certification of closure of each 
hazardous waste disposal unit, the owner or operator must submit to the 
local zoning authority, or the authority with jurisdiction over local 
land use, and to the Regional Administrator a record of the type, 
location, and quantity of hazardous wastes disposed of within each cell 
or other disposal unit of the facility. For hazardous wastes disposed of 
before January 12, 1981, the owner or operator must identify the type, 
location, and quantity of the hazardous wastes to the best of his 
knowledge and in accordance with any records he has kept.
    (b) Within 60 days of certification of closure of the first 
hazardous waste disposal unit and within 60 days of certification of 
closure of the last hazardous waste disposal unit, the owner or operator 
must:
    (1) Record, in accordance with State law, a notation on the deed to 
the facility property--or on some other instrument which is normally 
examined during title search--that will in perpetuity notify any 
potential purchaser of the property that:
    (i) The land has been used to manage hazardous wastes; and
    (ii) Its use is restricted under 40 CFR subpart G regulations; and
    (iii) The survey plat and record of the type, location, and quantity 
of hazardous wastes disposed of within each cell or other hazardous 
waste disposal unit of the facility required by Secs. 264.116 and 
264.119(a) have been filed with the local zoning authority or the 
authority with jurisdiction over local land use and with the Regional 
Administrator; and

[[Page 193]]

    (2) Submit a certification, signed by the owner or operator, that he 
has recorded the notation specified in paragraph (b)(1) of this section, 
including a copy of the document in which the notation has been placed, 
to the Regional Administrator.
    (c) If the owner or operator or any subsequent owner or operator of 
the land upon which a hazardous waste disposal unit is located wishes to 
remove hazardous wastes and hazardous waste residues, the liner, if any, 
or contaminated soils, he must request a modification to the post-
closure permit in accordance with the applicable requirements in parts 
124 and 270. The owner or operator must demonstrate that the removal of 
hazardous wastes will satisfy the criteria of Sec. 264.117(c). By 
removing hazardous waste, the owner or operator may become a generator 
of hazardous waste and must manage it in accordance with all applicable 
requirements of this chapter. If he is granted a permit modification or 
otherwise granted approval to conduct such removal activities, the owner 
or operator may request that the Regional Administrator approve either:
    (1) The removal of the notation on the deed to the facility property 
or other instrument normally examined during title search; or
    (2) The addition of a notation to the deed or instrument indicating 
the removal of the hazardous waste.



Sec. 264.120  Certification of completion of post-closure care.

    No later than 60 days after completion of the established post-
closure care period for each hazardous waste disposal unit, the owner or 
operator must submit to the Regional Administrator, by registered mail, 
a certification that the post-closure care period for the hazardous 
waste disposal unit was performed in accordance with the specifications 
in the approved post-closure plan. The certification must be signed by 
the owner or operator and an independent registered professional 
engineer. Documentation supporting the independent registered 
professional engineer's certification must be furnished to the Regional 
Administrator upon request until he releases the owner or operator from 
the financial assurance requirements for post-closure care under 
Sec. 264.145(i).

[[Page 194]]

    (e) Post-closure plan means the plan for post-closure care prepared 
in accordance with the requirements of Secs. 264.117 through 264.120.
    (f) The following terms are used in the specifications for the 
financial tests for closure, post-closure care, and liability coverage. 
The definitions are intended to assist in the understanding of these 
regulations and are not intended to limit the meanings of terms in a way 
that conflicts with generally accepted accounting practices.
    Assets means all existing and all probable future economic benefits 
obtained or controlled by a particular entity.
    Current assets means cash or other assets or resources commonly 
identified as those which are reasonably expected to be realized in cash 
or sold or consumed during the normal operating cycle of the business.
    Current liabilities means obligations whose liquidation is 
reasonably expected to require the use of existing resources properly 
classifiable as current assets or the creation of other current 
liabilities.
    Current plugging and abandonment cost estimate means the most recent 
of the estimates prepared in accordance with Sec. 144.62(a), (b), and 
(c) of this title.
    Independently audited refers to an audit performed by an independent 
certified public accountant in accordance with generally accepted 
auditing standards.
    Liabilities means probable future sacrifices of economic benefits 
arising from present obligations to transfer assets or provide services 
to other entities in the future as a result of past transactions or 
events.
    Net working capital means current assets minus current liabilities.
    Net worth means total assets minus total liabilities and is 
equivalent to owner's equity.
    Tangible net worth means the tangible assets that remain after 
deducting liabilities; such assets would not include intangibles such as 
goodwill and rights to patents or royalties.
    (g) In the liability insurance requirements the terms bodily injury 
and property damage shall have the meanings given these terms by 
applicable State law. However, these terms do not include those 
liabilities which, consistent with standard industry practices, are 
excluded from coverage in liability policies for bodily injury and 
property damage. The Agency intends the meanings of other terms used in 
the liability insurance requirements to be consistent with their common 
meanings within the insurance industry. The definitions given below of 
several of the terms are intended to assist in the understanding of 
these regulations and are not intended to limit their meanings in a way 
that conflicts with general insurance industry usage.
    Accidental occurrence means an accident, including continuous or 
repeated exposure to conditions, which results in bodily injury or 
property damage neither expected nor intended from the standpoint of the 
insured.
    Legal defense costs means any expenses that an insurer incurs in 
defending against claims of third parties brought under the terms and 
conditions of an insurance policy.
    Nonsudden accidental occurrence means an occurrence which takes 
place over time and involves continuous or repeated exposure.
    Sudden accidental occurrence means an occurrence which is not 
continuous or repeated in nature.
    (h) Substantial business relationship means the extent of a business 
relationship necessary under applicable State law to make a guarantee 
contract issued incident to that relationship valid and enforceable. A 
``substantial business relationship'' must arise from a pattern of 
recent or ongoing business transactions, in addition to the guarantee 
itself, such that a currently existing business relationship between the 
guarantor and the owner or operator is demonstrated to the satisfaction 
of the applicable EPA Regional Administrator.

FR 33950, Sept. 1, 1988]



Sec. 264.142  Cost estimate for closure.

    (a) The owner or operator must have a detailed written estimate, in 
current dollars, of the cost of closing the facility in accordance with 
the requirements in Secs. 264.111 through 264.115 and applicable closure 
requirements in

[[Page 195]]

Sec. Sec. 264.178, 264.197, 264.228, 264.258, 264.280, 264.310, 264.351, 
264.601 through 264.603, and 264.1102.
    (1) The estimate must equal the cost of final closure at the point 
in the facility's active life when the extent and manner of its 
operation would make closure the most expensive, as indicated by its 
closure plan (see Sec. 264.112(b)); and
    (2) The closure cost estimate must be based on the costs to the 
owner or operator of hiring a third party to close the facility. A third 
party is a party who is neither a parent nor a subsidiary of the owner 
or operator. (See definition of parent corporation in Sec. 264.141(d).) 
The owner or operator may use costs for on-site disposal if he can 
demonstrate that on-site disposal capacity will exist at all times over 
the life of the facility.
    (3) The closure cost estimate may not incorporate any salvage value 
that may be realized with the sale of hazardous wastes, or non-hazardous 
wastes if applicable under Sec. 264.113(d), facility structures or 
equipment, land, or other assets associated with the facility at the 
time of partial or final closure.
    (4) The owner or operator may not incorporate a zero cost for 
hazardous wastes, or non-hazardous wastes if applicable under 
Sec. 264.113(d), that might have economic value.
    (b) During the active life of the facility, the owner or operator 
must adjust the closure cost estimate for inflation within 60 days prior 
to the anniversary date of the establishment of the financial 
instrument(s) used to comply with Sec. 264.143. For owners and operators 
using the financial test or corporate guarantee, the closure cost 
estimate must be updated for inflation within 30 days after the close of 
the firm's fiscal year and before submission of updated information to 
the Regional Administrator as specified in Sec. 264.143(f)(3). The 
adjustment may be made by recalculating the maximum costs of closure in 
current dollars, or by using an inflation factor derived from the most 
recent Implicit Price Deflator for Gross National Product published by 
the U.S. Department of Commerce in its Survey of Current Business, as 
specified in paragraphs (b)(1) and (2) of this section. The inflation 
factor is the result of dividing the latest published annual Deflator by 
the Deflator for the previous year.
    (1) The first adjustment is made by multiplying the closure cost 
estimate by the inflation factor. The result is the adjusted closure 
cost estimate.
    (2) Subsequent adjustments are made by mutliplying the latest 
adjusted closure cost estimate by the latest inflation factor.
    (c) During the active life of the facility, the owner or operator 
must revise the closure cost estimate no later than 30 days after the 
Regional Administrator has approved the request to modify the closure 
plan, if the change in the closure plan increases the cost of closure. 
The revised closure cost estimate must be adjusted for inflation as 
specified in Sec. 264.142(b).
    (d) The owner or operator must keep the following at the facility 
during the operating life of the facility: The latest closure cost 
estimate prepared in accordance with Sec. 264.142 (a) and (c) and, when 
this estimate has been adjusted in accordance with Sec. 264.142(b), the 
latest adjusted closure cost estimate.

Sec. 264.143  Financial assurance for closure.

    An owner or operator of each facility must establish financial 
assurance for closure of the facility. He must choose from the options 
as specified in paragraphs (a) through (f) of this section.
    (a) Closure trust fund. (1) An owner or operator may satisfy the 
requirements of this section by establishing a closure trust fund which 
conforms to the requirements of this paragraph and submitting an 
originally signed duplicate of the trust agreement to the Regional 
Administrator. An owner or operator of a new facility must submit the 
originally signed duplicate of the trust agreement to the Regional 
Administrator at least 60 days before the date on which hazardous waste 
is first received for treatment, storage, or disposal. The trustee must 
be an entity which has the authority to act as a trustee and whose trust 
operations are regulated and examined by a Federal or State agency.

[[Page 196]]

    (2) The wording of the trust agreement must be identical to the 
wording specified in Sec. 264.151(a)(1), and the trust agreement must be 
accompanied by a formal certification of acknowledgment (for example, 
see Sec. 264.151(a)(2)). Schedule A of the trust agreement must be 
updated within 60 days after a change in the amount of the current 
closure cost estimate covered by the agreement.
    (3) Payments into the trust fund must be made annually by the owner 
or operator over the term of the initial RCRA permit or over the 
remaining operating life of the facility as estimated in the closure 
plan, whichever period is shorter; this period is hereafter referred to 
as the ``pay-in period.'' The payments into the closure trust fund must 
be made as follows:
    (i) For a new facility, the first payment must be made before the 
initial receipt of hazardous waste for treatment, storage, or disposal. 
A receipt from the trustee for this payment must be submitted by the 
owner or operator to the Regional Administrator before this initial 
receipt of hazardous waste. The first payment must be at least equal to 
the current closure cost estimate, except as provided in 
Sec. 264.143(g), divided by the number of years in the pay-in period. 
Subsequent payments must be made no later than 30 days after each 
anniversary date of the first payment. The amount of each subsequent 
payment must be determined by this formula:
[GRAPHIC] [TIFF OMITTED] TC01AU92.050

where CE is the current closure cost estimate, CV is the current value 
of the trust fund, and Y is the number of years remaining in the pay-in 
period.
    (ii) If an owner or operator establishes a trust fund as specified 
in Sec. 265.143(a) of this chapter, and the value of that trust fund is 
less than the current closure cost estimate when a permit is awarded for 
the facility, the amount of the current closure cost estimate still to 
be paid into the trust fund must be paid in over the pay-in period as 
defined in paragraph (a)(3) of this section. Payments must continue to 
be made no later than 30 days after each anniversary date of the first 
payment made pursuant to part 265 of this chapter. The amount of each 
payment must be determined by this formula:
[GRAPHIC] [TIFF OMITTED] TC01AU92.050

where CE is the current closure cost estimate, CV is the current value 
of the trust fund, and Y is the number of years remaining in the pay-in 
period.
    (4) The owner or operator may accelerate payments into the trust 
fund or he may deposit the full amount of the current closure cost 
estimate at the time the fund is established. However, he must maintain 
the value of the fund at no less than the value that the fund would have 
if annual payments were made as specified in paragraph (a)(3) of this 
section.
    (5) If the owner or operator establishes a closure trust fund after 
having used one or more alternate mechanisms specified in this section 
or in Sec. 265.143 of this chapter, his first payment must be in at 
least the amount that the fund would contain if the trust fund were 
established initially and annual payments made according to 
specifications of this paragraph and Sec. 265.143(a) of this chapter, as 
applicable.
    (6) After the pay-in period is completed, whenever the current 
closure cost estimate changes, the owner or operator must compare the 
new estimate with the trustee's most recent annual valuation of the 
trust fund. If the value of the fund is less than the amount of the new 
estimate, the owner or operator, within 60 days after the change in the 
cost estimate, must either deposit an amount into the fund so that its 
value after this deposit at least equals the amount of the current 
closure cost estimate, or obtain other financial assurance as specified 
in this section to cover the difference.
    (7) If the value of the trust fund is greater than the total amount 
of the current closure cost estimate, the owner or operator may submit a 
written request to the Regional Administrator for release of the amount 
in excess of the current closure cost estimate.
    (8) If an owner or operator substitutes other financial assurance as

[[Page 197]]

specified in this section for all or part of the trust fund, he may 
submit a written request to the Regional Administrator for release of 
the amount in excess of the current closure cost estimate covered by the 
trust fund.
    (9) Within 60 days after receiving a request from the owner or 
operator for release of funds as specified in paragraph (a) (7) or (8) 
of this section, the Regional Administrator will instruct the trustee to 
release to the owner or operator such funds as the Regional 
Administrator specifies in writing.
    (10) After beginning partial or final closure, an owner or operator 
or another person authorized to conduct partial or final closure may 
request reimbursements for partial or final closure expenditures by 
submitting itemized bills to the Regional Administrator. The owner or 
operator may request reimbursements for partial closure only if 
sufficient funds are remaining in the trust fund to cover the maximum 
costs of closing the facility over its remaining operating life. Within 
60 days after receiving bills for partial or final closure activities, 
the Regional Administrator will instruct the trustee to make 
reimbursements in those amounts as the Regional Administrator specifies 
in writing, if the Regional Administrator determines that the partial or 
final closure expenditures are in accordance with the approved closure 
plan, or otherwise justified. If the Regional Administrator has reason 
to believe that the maximum cost of closure over the remaining life of 
the facility will be significantly greater than the value of the trust 
fund, he may withhold reimbursements of such amounts as he deems prudent 
until he determines, in accordance with Sec. 264.143(i) that the owner 
or operator is no longer required to maintain financial assurance for 
final closure of the facility. If the Regional Administrator does not 
instruct the trustee to make such reimbursements, he will provide the 
owner or operator with a detailed written statement of reasons.
    (11) The Regional Administrator will agree to termination of the 
trust when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.143(i).
    (b) Surety bond guaranteeing payment into a closure trust fund. (1) 
An owner or operator may satisfy the requirements of this section by 
obtaining a surety bond which conforms to the requirements of this 
paragraph and submitting the bond to the Regional Administrator. An 
owner or operator of a new facility must submit the bond to the Regional 
Administrator at least 60 days before the date on which hazardous waste 
is first received for treatment, storage, or disposal. The bond must be 
effective before this initial receipt of hazardous waste. The surety 
company issuing the bond must, at a minimum, be among those listed as 
acceptable sureties on Federal bonds in Circular 570 of the U.S. 
Department of the Treasury.
    (2) The wording of the surety bond must be identical to the wording 
specified in Sec. 264.151(b).
    (3) The owner or operator who uses a surety bond to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the bond, all payments made thereunder will be 
deposited by the surety directly into the standby trust fund in 
accordance with instructions from the Regional Administrator. This 
standby trust fund must meet the requirements specified in 
Sec. 264.143(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the surety bond; and
    (ii) Until the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:
    (A) Payments into the trust fund as specified in Sec. 264.143(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The bond must guarantee that the owner or operator will:

[[Page 198]]

    (i) Fund the standby trust fund in an amount equal to the penal sum 
of the bond before the beginning of final closure of the facility; or
    (ii) Fund the standby trust fund in an amount equal to the penal sum 
within 15 days after an administrative order to begin final closure 
issued by the Regional Administrator becomes final, or within 15 days 
after an order to begin final closure is issued by a U.S. district court 
or other court of competent jurisdiction; or
    (iii) Provide alternate financial assurance as specified in this 
section, and obtain the Regional Administrator's written approval of the 
assurance provided, within 90 days after receipt by both the owner or 
operator and the Regional Administrator of a notice of cancellation of 
the bond from the surety.
    (5) Under the terms of the bond, the surety will become liable on 
the bond obligation when the owner or operator fails to perform as 
guaranteed by the bond.
    (6) The penal sum of the bond must be in an amount at least equal to 
the current closure cost estimate, except as provided in 
Sec. 264.143(g).
    (7) Whenever the current closure cost estimate increases to an 
amount greater then the penal sum, the owner or operator, within 60 days 
after the increase, must either cause the penal sum to be increased to 
an amount at least equal to the current closure cost estimate and submit 
evidence of such increase to the Regional Administrator, or obtain other 
financial assurance as specified in this section to cover the increase. 
Whenever the current closure cost estimate decreases, the penal sum may 
be reduced to the amount of the current closure cost estimate following 
written approval by the Regional Administrator.
    (8) Under the terms of the bond, the surety may cancel the bond by 
sending notice of cancellation by certified mail to the owner or 
operator and to the  Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidence by the return receipts.
    (9) The owner or operator may cancel the bond if the Regional 
Administrator has given prior written consent based on his receipt of 
evidence of alternate financial assurance as specified in this section.
    (c) Surety bond guaranteeing performance of closure. (1) An owner or 
operator may satisfy the requirements of this section by obtaining a 
surety bond which conforms to the requirements of this paragraph and 
submitting the bond to the Regional Administrator. An owner or operator 
of a new facility must submit the bond to the Regional Administrator at 
least 60 days before the date on which hazardous waste is first received 
for treatment, storage, or disposal. The bond must be effective before 
this initial receipt of hazardous waste. The surety company issuing the 
bond must, at a minimum, be among those listed as acceptable sureties on 
Federal bonds in Circular 570 of the U.S. Department of the Treasury.
    (2) The wording of the surety bond must be identical to the wording 
specified in Sec. 264.151(c).
    (3) The owner or operator who uses a surety bond to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the bond, all payments made thereunder will be 
deposited by the surety directly into the standby trust fund in 
accordance with instructions from the Regional Administrator. This 
standby trust must meet the requirements specified in Sec. 264.143(a), 
except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the surety bond; and
    (ii) Unless the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:
    (A) Payments into the trust fund as specified in Sec. 264.143(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The bond must guarantee that the owner or operator will:

[[Page 199]]

    (i) Perform final closure in accordance with the closure plan and 
other requirements of the permit for the facility whenever required to 
do so; or
    (ii) Provide alternate financial assurance as specified in this 
section, and obtain the Regional Administrator's written approval of the 
assurance provided, within 90 days after receipt by both the owner or 
operator and the Regional Administrator of a notice of cancellation of 
the bond from the surety.
    (5) Under the terms of the bond, the surety will become liable on 
the bond obligation when the owner or operator fails to perform as 
guaranteed by the bond. Following a final administrative determination 
pursuant to section 3008 of RCRA that the owner or operator has failed 
to perform final closure in accordance with the approved closure plan 
and other permit requirements when required to do so, under the terms of 
the bond the surety will perform final closure as guaranteed by the bond 
or will deposit the amount of the penal sum into the standby trust fund.
    (6) The penal sum of the bond must be in an amount at least equal to 
the current closure cost estimate.
    (7) Whenever the current closure cost estimate increases to an 
amount greater than the penal sum, the owner or operator, within 60 days 
after the increase, must either cause the penal sum to be increased to 
an amount at least equal to the current closure cost estimate and submit 
evidence of such increase to the Regional Administrator, or obtain other 
financial assurance as specified in this section. Whenever the current 
closure cost estimate decreases, the penal sum may be reduced to the 
amount of the current closure cost estimate following written approval 
by the Regional Administrator.
    (8) Under the terms of the bond, the surety may cancel the bond by 
sending notice of cancellation by certified mail to the owner or 
operator and to the Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (9) The owner or operator may cancel the bond if the Regional 
Administrator has given prior written consent. The Regional 
Administrator will provide such written consent when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.143(i).
    (10) The surety will not be liable for deficiencies in the 
performance of closure by the owner or operator after the Regional 
Administrator releases the owner or operator from the requirements of 
this section in accordance with Sec. 264.143(i).
    (d) Closure letter of credit. (1) An owner or operator may satisfy 
the requirements of this section by obtaining an irrevocable standby 
letter of credit which conforms to the requirements of this paragraph 
and submitting the letter to the Regional Administrator. An owner or 
operator of a new facility must submit the letter of credit to the 
Regional Administrator at least 60 days before the date on which 
hazardous waste is first received for treatment, storage, or disposal. 
The letter of credit must be effective before this initial receipt of 
hazardous waste. The issuing institution must be an entity which has the 
authority to issue letters of credit and whose letter-of-credit 
operations are regulated and examined by a Federal or State agency.
    (2) The wording of the letter of credit must be identical to the 
wording specified in Sec. 264.151(d).
    (3) An owner or operator who uses a letter of credit to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the letter of credit, all amounts paid pursuant to a 
draft by the Regional Administrator will be deposited by the issuing 
institution directly into the standby trust fund in accordance with 
instructions from the Regional Administrator. This standby trust fund 
must meet the requirements of the trust fund specified in 
Sec. 264.143(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted

[[Page 200]]

to the Regional Administrator with the letter of credit; and
    (ii) Unless the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:
    (A) Payments into the trust fund as specified in Sec. 264.143(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The letter of credit must be accompanied by a letter from the 
owner or operator referring to the letter of credit by number, issuing 
institution, and date, and providing the following information: the EPA 
Identification Number, name, and address of the facility, and the amount 
of funds assured for closure of the facility by the letter of credit.
    (5) The letter of credit must be irrevocable and issued for a period 
of at least 1 year. The letter of credit must provide that the 
expiration date will be automatically extended for a period of at least 
1 year unless, at least 120 days before the current expiration date, the 
issuing institution notifies both the owner or operator and the Regional 
Administrator by certified mail of a decision not to extend the 
expiration date. Under the terms of the letter of credit, the 120 days 
will begin on the date when both the owner or operator and the Regional 
Administrator have received the notice, as evidenced by the return 
receipts.
    (6) The letter of credit must be issued in an amount at least equal 
to the current closure cost estimate, except as provided in 
Sec. 264.143(g).
    (7) Whenever the current closure cost estimate increases to an 
amount greater than the amount of the credit, the owner or operator, 
within 60 days after the increase, must either cause the amount of the 
credit to be increased so that it at least equals the current closure 
cost estimate and submit evidence of such increase to the Regional 
Administrator, or obtain other financial assurance as specified in this 
section to cover the increase. Whenever the current closure cost 
estimate decreases, the amount of the credit may be reduced to the 
amount of the current closure cost estimate following written approval 
by the Regional Administrator.
    (8) Following a final administrative determination pursuant to 
section 3008 of RCRA that the owner or operator has failed to perform 
final closure in accordance with the closure plan and other permit 
requirements when required to do so, the Regional Administrator may draw 
on the letter of credit.
    (9) If the owner or operator does not establish alternate financial 
assurance as specified in this section and obtain written approval of 
such alternate assurance from the Regional Administrator within 90 days 
after receipt by both the owner or operator and the Regional 
Administrator of a notice from issuing institution that it has decided 
not to extend the letter of credit beyond the current expiration date, 
the Regional Administrator will draw on the letter of credit. The 
Regional Administrator may delay the drawing if the issuing institution 
grants an extension of the term of the credit. During the last 30 days 
of any such extension the Regional Administrator will draw on the letter 
of credit if the owner or operator has failed to provide alternate 
financial assurance as specified in this section and obtain written 
approval of such assurance from the Regional Administrator.
    (10) The Regional Administrator will return the letter of credit to 
the issuing institution for termination when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.143(i).
    (e) Closure insurance. (1) An owner or operator may satisfy the 
requirements of this section by obtaining closure insurance which 
conforms to the requirements of this paragraph and submitting a 
certificate of such insurance to the Regional Administrator. An owner or 
operator of a new facility must submit the certificate of insurance to 
the Regional Administrator at least 60

[[Page 201]]

days before the date on which hazardous waste is first received for 
treatment, storage, or disposal. The insurance must be effective before 
this initial receipt of hazardous waste. At a minimum, the insurer must 
be licensed to transact the business of insurance, or eligible to 
provide insurance as an excess or surplus lines insurer, in one or more 
States.
    (2) The wording of the certificate of insurance must be identical to 
the wording specified in Sec. 264.151(e).
    (3) The closure insurance policy must be issued for a face amount at 
least equal to the current closure cost estimate, except as provided in 
Sec. 264.143(g). The term ``face amount'' means the total amount the 
insurer is obligated to pay under the policy. Actual payments by the 
insurer will not change the face amount, although the insurer's future 
liability will be lowered by the amount of the payments.
    (4) The closure insurance policy must guarantee that funds will be 
available to close the facility whenever final closure occurs. The 
policy must also guarantee that once final closure begins, the insurer 
will be responsible for paying out funds, up to an amount equal to the 
face amount of the policy, upon the direction of the Regional 
Administrator, to such party or parties as the Regional Administrator 
specifies.
    (5) After beginning partial or final closure, an owner or operator 
or any other person authorized to conduct closure may request 
reimbursements for closure expenditures by submitting itemized bills to 
the Regional Administrator. The owner or operator may request 
reimbursements for partial closure only if the remaining value of the 
policy is sufficient to cover the maximum costs of closing the facility 
over its remaining operating life. Within 60 days after receiving bills 
for closure activities, the Regional Administrator will instruct the 
insurer to make reimbursements in such amounts as the Regional 
Administrator specifies in writing, if the Regional Administrator 
determines that the partial or final closure expenditures are in 
accordance with the approved closure plan or otherwise justified. If the 
Regional Administrator has reason to believe that the maximum cost of 
closure over the remaining life of the facility will be signficantly 
greater than the face amount of the policy, he may withhold 
reimbursements of such amounts as he deems prudent until he determines, 
in accordance with Sec. 264.143(i), that the owner or operator is no 
longer required to maintain financial assurance for final closure of the 
facility. If the Regional Administrator does not instruct the insurer to 
make such reimbursements, he will provide the owner or operator with a 
detailed written statement of reasons.
    (6) The owner or operator must maintain the policy in full force and 
effect until the Regional Administrator consents to termination of the 
policy by the owner or operator as specified in paragraph (e)(10) of 
this section. Failure to pay the premium, without substitution of 
alternate financial assurance as specified in this section, will 
constitute a significant violation of these regulations, warranting such 
remedy as the Regional Administrator deems necessary. Such violation 
will be deemed to begin upon receipt by the Regional Administrator of a 
notice of future cancellation, termination, or failure to renew due to 
nonpayment of the premium, rather than upon the date of expiration.
    (7) Each policy must contain a provision allowing assignment of the 
policy to a successor owner or operator. Such assignment may be 
conditional upon consent of the insurer, provided such consent is not 
unreasonably refused.
    (8) The policy must provide that the insurer may not cancel, 
terminate, or fail to renew the policy except for failure to pay the 
premium. The automatic renewal of the policy must, at a minimum, provide 
the insured with the option of renewal at the face amount of the 
expiring policy. If there is a failure to pay the premium, the insurer 
may elect to cancel, terminate, or fail to renew the policy by sending 
notice by certified mail to the owner or operator and the Regional 
Administrator. Cancellation, termination, or failure to renew may not 
occur, however, during the 120 days beginning with the date of receipt 
of the notice by both the Regional Administrator and the owner or 
operator, as evidenced by the return receipts. Cancellation, 
termination, or

[[Page 202]]

failure to renew may not occur and the policy will remain in full force 
and effect in the event that on or before the date of expiration:
    (i) The Regional Administrator deems the facility abandoned; or
    (ii) The permit is terminated or revoked or a new permit is denied; 
or
    (iii) Closure is ordered by the Regional Administrator or a U.S. 
district court or other court of competent jurisdiction; or
    (iv) The owner or operator is named as debtor in a voluntary or 
involuntary proceeding under Title 11 (Bankruptcy), U.S. Code; or
    (v) The premium due is paid.
    (9) Whenever the current closure cost estimate increases to an 
amount greater than the face amount of the policy, the owner or 
operator, within 60 days after the increase, must either cause the face 
amount to be increased to an amount at least equal to the current 
closure cost estimate and submit evidence of such increase to the 
Regional Administrator, or obtain other financial assurance as specified 
in this section to cover the increase. Whenever the current closure cost 
estimate decreases, the face amount may be reduced to the amount of the 
current closure cost estimate following written approval by the Regional 
Administrator.
    (10) The Regional Administrator will give written consent to the 
owner or operator that he may terminate the insurance policy when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.143(i).
    (f) Financial test and corporate guarantee for closure. (1) An owner 
or operator may satisfy the requirements of this section by 
demonstrating that he passes a financial test as specified in this 
paragraph. To pass this test the owner or operator must meet the 
criteria of either paragraph (f)(1)(i) or (ii) of this section:
    (i) The owner or operator must have:
    (A) Two of the following three ratios: a ratio of total liabilities 
to net worth less than 2.0; a ratio of the sum of net income plus 
depreciation, depletion, and amortization to total liabilities greater 
than 0.1; and a ratio of current assets to current liabilities greater 
than 1.5; and
    (B) Net working capital and tangible net worth each at least six 
times the sum of the current closure and post-closure cost estimates and 
the current plugging and abandonment cost estimates; and
    (C) Tangible net worth of at least $10 million; and
    (D) Assets located in the United States amounting to at least 90 
percent of total assets or at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates.
    (ii) The owner or operator must have:
    (A) A current rating for his most recent bond issuance of AAA, AA, 
A, or BBB as issued by Standard and Poor's or Aaa, Aa, A, or Baa as 
issued by Moody's; and
    (B) Tangible net worth at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates; and
    (C) Tangible net worth of at least $10 million; and
    (D) Assets located in the United States amounting to at least 90 
percent of total assets or at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates.
    (2) The phrase ``current closure and post-closure cost estimates'' 
as used in paragraph (f)(1) of this section refers to the cost estimates 
required to be shown in paragraphs 1-4 of the letter from the owner's or 
operator's chief financial officer (Sec. 264.151(f)). The phrase 
``current plugging and abandonment cost estimates'' as used in paragraph 
(f)(1) of this section refers to the cost estimates required to be shown 
in paragraphs 1-4 of the letter from the owner's or operator's chief 
financial officer (Sec. 144.70(f) of this title).
    (3) To demonstrate that he meets this test, the owner or operator 
must submit the following items to the Regional Administrator:

[[Page 203]]

    (i) A letter signed by the owner's or operator's chief financial 
officer and worded as specified in Sec. 264.151(f); and
    (ii) A copy of the independent certified public accountant's report 
on examination of the owner's or operator's financial statements for the 
latest completed fiscal year; and
    (iii) A special report from the owner's or operator's independent 
certified public accountant to the owner or operator stating that:
    (A) He has compared the data which the letter from the chief 
financial officer specifies as having been derived from the 
independently audited, year-end financial statements for the latest 
fiscal year with the amounts in such financial statements; and
    (B) In connection with that procedure, no matters came to his 
attention which caused him to believe that the specified data should be 
adjusted.
    (4) An owner or operator of a new facility must submit the items 
specified in paragraph (f)(3) of this section to the Regional 
Administrator at least 60 days before the date on which hazardous waste 
is first received for treatment, storage, or disposal.
    (5) After the initial submission of items specified in paragraph 
(f)(3) of this section, the owner or operator must send updated 
information to the Regional Administrator within 90 days after the close 
of each succeeding fiscal year. This information must consist of all 
three items specified in paragraph (f)(3) of this section.
    (6) If the owner or operator no longer meets the requirements of 
paragraph (f)(1) of this section, he must send notice to the Regional 
Administrator of intent to establish alternate financial assurance as 
specified in this section. The notice must be sent by certified mail 
within 90 days after the end of the fiscal year for which the year-end 
financial data show that the owner or operator no longer meets the 
requirements. The owner or operator must provide the alternate financial 
assurance within 120 days after the end of such fiscal year.
    (7) The Regional Administrator may, based on a reasonable belief 
that the owner or operator may no longer meet the requirements of 
paragraph (f)(1) of this section, require reports of financial condition 
at any time from the owner or operator in addition to those specified in 
paragraph (f)(3) of this section. If the Regional Administrator finds, 
on the basis of such reports or other information, that the owner or 
operator no longer meets the requirements of paragraph (f)(1) of this 
section, the owner or operator must provide alternate financial 
assurance as specified in this section within 30 days after notification 
of such a finding.
    (8) The Regional Administrator may disallow use of this test on the 
basis of qualifications in the opinion expressed by the independent 
certified public accountant in his report on examination of the owner's 
or operator's financial statements (see paragraph (f)(3)(ii) of this 
section). An adverse opinion or a disclaimer of opinion will be cause 
for disallowance. The Regional Administrator will evaluate other 
qualifications on an individual basis. The owner or operator must 
provide alternate financial assurance as specified in this section 
within 30 days after notification of the disallowance.
    (9) The owner or operator is no longer required to submit the items 
specified in paragraph (f)(3) of this section when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.143(i).
    (10) An owner or operator may meet the requirements of this section 
by obtaining a written guarantee. The guarantor must be the direct or 
higher-tier parent corporation of the owner or operator, a firm whose 
parent corporation is also the parent corporation of the owner or 
operator, or a firm with a ``substantial business relationship'' with 
the owner or operator. The guarantor must meet the requirements for 
owners or operators in paragraphs (f)(1) through (8) of this section and 
must comply with the terms of the guarantee. The wording of the 
guarantee must be identical to the wording specified in Sec. 264.151(h). 
The certified copy of the guarantee must accompany the items sent to the 
Regional Administrator as specified in paragraph (f)(3) of this section. 
One of these items must be the

[[Page 204]]

letter from the guarantor's chief financial officer. If the guarantor's 
parent corporation is also the parent corporation of the owner or 
operator, the letter must describe the value received in consideration 
of the guarantee. If the guarantor is a firm with a ``substantial 
business relationship'' with the owner or operator, this letter must 
describe this ``substantial business relationship'' and the value 
received in consideration of the guarantee. The terms of the guarantee 
must provide that:
    (i) If the owner or operator fails to perform final closure of a 
facility covered by the corporate guarantee in accordance with the 
closure plan and other permit requirements whenever required to do so, 
the guarantor will do so or establish a trust fund as specified in 
Sec. 264.143(a) in the name of the owner or operator.
    (ii) The corporate guarantee will remain in force unless the 
guarantor sends notice of cancellation by certified mail to the owner or 
operator and to the Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (iii) If the owner or operator fails to provide alternate financial 
assurance as specified in this section and obtain the written approval 
of such alternate assurance from the Regional Administrator within 90 
days after receipt by both the owner or operator and the Regional 
Administrator of a notice of cancellation of the corporate guarantee 
from the guarantor, the guarantor will provide such alternative 
financial assurance in the name of the owner or operator.
    (g) Use of multiple financial mechanisms. An owner or operator may 
satisfy the requirements of this section by establishing more than one 
financial mechanism per facility. These mechanisms are limited to trust 
funds, surety bonds guaranteeing payment into a trust fund, letters of 
credit, and insurance. The mechanisms must be as specified in paragraphs 
(a), (b), (d), and (e), respectively, of this section, except that it is 
the combination of mechanisms, rather than the single mechanism, which 
must provide financial assurance for an amount at least equal to the 
current closure cost estimate. If an owner or operator uses a trust fund 
in combination with a surety bond or a letter of credit, he may use the 
trust fund as the standby trust fund for the other mechanisms. A single 
standby trust fund may be established for two or more mechanisms. The 
Regional Administrator may use any or all of the mechanisms to provide 
for closure of the facility.
    (h) Use of a financial mechanism for multiple facilities. An owner 
or operator may use a financial assurance mechanism specified in this 
section to meet the requirements of this section for more than one 
facility. Evidence of financial assurance submitted to the Regional 
Administrator must include a list showing, for each facility, the EPA 
Identification Number, name, address, and the amount of funds for 
closure assured by the mechanism. If the facilities covered by the 
mechanism are in more than one Region, identical evidence of financial 
assurance must be submitted to and maintained with the Regional 
Administrators of all such Regions. The amount of funds available 
through the mechanism must be no less than the sum of funds that would 
be available if a separate mechanism had been established and maintained 
for each facility. In directing funds available through the mechanism 
for closure of any of the facilities covered by the mechanism, the 
Regional Administrator may direct only the amount of funds designated 
for that facility, unless the owner or operator agrees to the use of 
additional funds available under the mechanism.
    (i) Release of the owner or operator from the requirements of this 
section. Within 60 days after receiving certifications from the owner or 
operator and an independent registered professional engineer that final 
closure has been completed in accordance with the approved closure plan, 
the Regional Administrator will notify the owner or operator in writing 
that he is no longer required by this section to maintain financial 
assurance for final closure of the facility, unless the Regional 
Administrator has reason to believe that

[[Page 205]]

final closure has not been in accordance with the approved closure plan. 
The Regional Administrator shall provide the owner or operator a 
detailed written statement of any such reason to believe that closure 
has not been in accordance with the approved closure plan.

Sec. 264.144  Cost estimate for post-closure care.

    (a) The owner or operator of a disposal surface impoundment, 
disposal miscellaneous unit, land treatment unit, or landfill unit, or 
of a surface impoundment or waste pile required under Secs. 264.228 and 
264.258 to prepare a contingent closure and post-closure plan, must have 
a detailed written estimate, in current dollars, of the annual cost of 
post-closure monitoring and maintenance of the facility in accordance 
with the applicable post-closure regulations in Secs. 264.117 through 
264.120, 264.228, 264.258, 264.280, 264.310, and 264.603.
    (1) The post-closure cost estimate must be based on the costs to the 
owner or operator of hiring a third party to conduct post-closure care 
activities. A third party is a party who is neither a parent nor a 
subsidiary of the owner or operator. (See definition of parent 
corporation in Sec. 264.141(d).)
    (2) The post-closure cost estimate is calculated by multiplying the 
annual post-closure cost estimate by the number of years of post-closure 
care required under Sec. 264.117.
    (b) During the active life of the facility, the owner or operator 
must adjust the post-closure cost estimate for inflation within 60 days 
prior to the anniversary date of the establishment of the financial 
instrument(s) used to comply with Sec. 264.145. For owners or operators 
using the financial test or corporate guarantee, the post-closure cost 
estimate must be updated for inflation within 30 days after the close of 
the firm's fiscal year and before the submission of updated information 
to the Regional Administrator as specified in Sec. 264.145(f)(5). The 
adjustment may be made by recalculating the post-closure cost estimate 
in current dollars or by using an inflation factor derived from the most 
recent Implicit Price Deflator for Gross National Product published by 
the U.S. Department of Commerce in its Survey of Current Business as 
specified in Sec. 264.145(b)(1) and (2). The inflation factor is the 
result of dividing the latest published annual Deflator by the Deflator 
for the previous year.
    (1) The first adjustment is made by multiplying the post-closure 
cost estimate by the inflation factor. The result is the adjusted post-
closure cost estimate.
    (2) Subsequent adjustments are made by multiplying the latest 
adjusted post-closure cost estimate by the latest inflation factor.
    (c) During the active life of the facility, the owner or operator 
must revise the post-closure cost estimate within 30 days after the 
Regional Administrator has approved the request to modify the post-
closure plan, if the change in the post-closure plan increases the cost 
of post-closure care. The revised post-closure cost estimate must be 
adjusted for inflation as specified in Sec. 264.144(b).
    (d) The owner or operator must keep the following at the facility 
during the operating life of the facility: The latest post-closure cost 
estimate prepared in accordance with Sec. 264.144 (a) and (c) and, when 
this estimate has been adjusted in accordance with Sec. 264.144(b), the 
latest adjusted post-closure cost estimate.

Sec. 264.145  Financial assurance for post-closure care.

    The owner or operator of a hazardous waste management unit subject 
to the requirements of Sec. 264.144 must establish financial assurance 
for post-closure care in accordance with the approved post-closure plan 
for the facility 60 days prior to the initial receipt of hazardous waste 
or the effective date of the regulation, whichever is later. He must 
choose from the following options:

[[Page 206]]

    (a) Post-closure trust fund. (1) An owner or operator may satisfy 
the requirements of this section by establishing a post-closure trust 
fund which conforms to the requirements of this paragraph and submitting 
an originally signed duplicate of the trust agreement to the Regional 
Administrator. An owner or operator of a new facility must submit the 
originally signed duplicate of the trust agreement to the Regional 
Administrator at least 60 days before the date on which hazardous waste 
is first received for disposal. The trustee must be an entity which has 
the authority to act as a trustee and whose trust operations are 
regulated and examined by a Federal or State agency.
    (2) The wording of the trust agreement must be identical to the 
wording specified in Sec. 264.151(a)(1), and the trust agreement must be 
accompanied by a formal certification of acknowledgment (for example, 
see Sec. 264.151(a)(2)). Schedule A of the trust agreement must be 
updated within 60 days after a change in the amount of the current post-
closure cost estimate covered by the agreement.
    (3) Payments into the trust fund must be made annually by the owner 
or operator over the term of the initial RCRA permit or over the 
remaining operating life of the facility as estimated in the closure 
plan, whichever period is shorter; this period is hereafter referred to 
as the ``pay-in period.'' The payments into the post-closure trust fund 
must be made as follows:
    (i) For a new facility, the first payment must be made before the 
initial receipt of hazardous waste for disposal. A receipt from the 
trustee for this payment must be submitted by the owner or operator to 
the Regional Administrator before this initial receipt of hazardous 
waste. The first payment must be at least equal to the current post-
closure cost estimate, except as provided in Sec. 264.145(g), divided by 
the number of years in the pay-in period. Subsequent payments must be 
made no later than 30 days after each anniversay date of the first 
payment. The amount of each subsequent payment must be determined by 
this formula:

[GRAPHIC] [TIFF OMITTED] TC01AU92.050

where CE is the current post-closure cost estimate, CV is the current 
value of the trust fund, and Y is the number of years remaining in the 
pay-in period.
    (ii) If an owner or operator establishes a trust fund as specified 
in Sec. 265.145(a) of this chapter, and the value of that trust fund is 
less than the current post-closure cost estimate when a permit is 
awarded for the facility, the amount of the current post-closure cost 
estimate still to be paid into the fund must be paid in over the pay-in 
period as defined in paragraph (a)(3) of this section. Payments must 
continue to be made no later than 30 days after each anniversary date of 
the first payment made pursuant to Part 265 of this chapter. The amount 
of each payment must be determined by this formula:

[GRAPHIC] [TIFF OMITTED] TC01AU92.050

where CE is the current post-closure cost estimate, CV is the current 
value of the trust fund, and Y is the number of years remaining in the 
pay-in period.
    (4) The owner or operator may accelerate payments into the trust 
fund or he may deposit the full amount of the current post-closure cost 
estimate at the time the fund is established. However, he must maintain 
the value of the fund at no less than the value that the fund would have 
if annual payments were made as specified in paragraph (a)(3) of this 
section.
    (5) If the owner or operator establishes a post-closure trust fund 
after having used one or more alternate mechanisms specified in this 
section or in Sec. 265.145 of this chapter, his first payment must be in 
at least the amount that the fund would contain if the trust fund were 
established initially and annual payments made according to 
specifications of this paragraph and Sec. 265.145(a) of this chapter, as 
applicable.
    (6) After the pay-in period is completed, whenever the current post-
closure cost estimate changes during the operating life of the facility, 
the owner

[[Page 207]]

or operator must compare the new estimate with the trustee's most recent 
annual valuation of the trust fund. If the value of the fund is less 
than the amount of the new estimate, the owner or operator, within 60 
days after the change in the cost estimate, must either deposit an 
amount into the fund so that its value after this deposit at least 
equals the amount of the current post-closure cost estimate, or obtain 
other financial assurance as specified in this section to cover the 
difference.
    (7) During the operating life of the facility, if the value of the 
trust fund is greater than the total amount of the current post-closure 
cost estimate, the owner or operator may submit a written request to the 
Regional Administrator for release of the amount in excess of the 
current post-closure cost estimate.
    (8) If an owner or operator substitutes other financial assurance as 
specified in this section for all or part of the trust fund, he may 
submit a written request to the Regional Administrator for release of 
the amount in excess of the current post-closure cost estimate covered 
by the trust fund.
    (9) Within 60 days after receiving a request from the owner or 
operator for release of funds as specified in paragraph (a) (7) or (8) 
of this section, the Regional Administrator will instruct the trustee to 
release to the owner or operator such funds as the Regional 
Administrator specifies in writing.
    (10) During the period of post-closure care, the Regional 
Administrator may approve a release of funds if the owner or operator 
demonstrates to the Regional Administrator that the value of the trust 
fund exceeds the remaining cost of post-closure care.
    (11) An owner or operator or any other person authorized to conduct 
post-closure care may request reimbursements for post-closure care 
expenditures by submitting itemized bills to the Regional Administrator. 
Within 60 days after receiving bills for post-closure care activities, 
the Regional Administrator will instruct the trustee to make 
reimbursements in those amounts as the Regional Administrator specifies 
in writing, if the Regional Administrator determines that the post-
closure care expenditures are in accordance with the approved post-
closure plan or otherwise justified. If the Regional Administrator does 
not instruct the trustee to make such reimbursements, he will provide 
the owner or operator with a detailed written statement of reasons.
    (12) The Regional Administrator will agree to termination of the 
trust when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.145(i).
    (b) Surety bond guaranteeing payment into a post-closure trust fund. 
(1) An owner or operator may satisfy the requirements of this section by 
obtaining a surety bond which conforms to the requirements of this 
paragraph and submitting the bond to the Regional Administrator. An 
owner or operator of a new facility must submit the bond to the Regional 
Administrator at least 60 days before the date on which hazardous waste 
is first received for disposal. The bond must be effective before this 
initial receipt of hazardous waste. The surety company issuing the bond 
must, at a minimum, be among those listed as acceptable sureties on 
Federal bonds in Circular 570 of the U.S. Department of the Treasury.
    (2) The wording of the surety bond must be identical to the wording 
specified in Sec. 264.151(b).
    (3) The owner or operator who uses a surety bond to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the bond, all payments made thereunder will be 
deposited by the surety directly into the standby trust fund in 
accordance with instructions from the Regional Administrator. This 
standby trust fund must meet the requirements specified in 
Sec. 264.145(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the surety bond; and
    (ii) Until the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:

[[Page 208]]

    (A) Payments into the trust fund as specified in Sec. 264.145(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current post-closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The bond must guarantee that the owner or operator will:
    (i) Fund the standby trust fund in an amount equal to the penal sum 
of the bond before the beginning of final closure of the facility; or
    (ii) Fund the standby trust fund in an amount equal to the penal sum 
within 15 days after an administrative order to begin final closure 
issued by the Regional Administrator becomes final, or within 15 days 
after an order to begin final closure is issued by a U.S. district court 
or other court of competent jurisdiction; or
    (iii) Provide alternate financial assurance as specified in this 
section, and obtain the Regional Administrator's written approval of the 
assurance provided, within 90 days after receipt by both the owner or 
operator and the Regional Administrator of a notice of cancellation of 
the bond from the surety.
    (5) Under the terms of the bond, the surety will become liable on 
the bond obligation when the owner or operator fails to perform as 
guaranteed by the bond.
    (6) The penal sum of the bond must be in an amount at least equal to 
the current post-closure cost estimate, except as provided in 
Sec. 264.145(g).
    (7) Whenever the current post-closure cost estimate increases to an 
amount greater than the penal sum, the owner or operator, within 60 days 
after the increase, must either cause the penal sum to be increased to 
an amount at least equal to the current post-closure cost estimate and 
submit evidence of such increase to the Regional Administrator, or 
obtain other financial assurance as specified in this section to cover 
the increase. Whenever the current post-closure cost estimate decreases, 
the penal sum may be reduced to the amount of the current post-closure 
cost estimate following written approval by the Regional Administrator.
    (8) Under the terms of the bond, the surety may cancel the bond by 
sending notice of cancellation by certified mail to the owner or 
operator and to the Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (9) The owner or operator may cancel the bond if the Regional 
Administrator has given prior written consent based on his receipt of 
evidence of alternate financial assurance as specified in this section.
    (c) Surety bond guaranteeing performance of post-closure care. (1) 
An owner or operator may satisfy the requirements of this section by 
obtaining a surety bond which conforms to the requirements of this 
paragraph and submitting the bond to the Regional Administrator. An 
owner or operator of a new facility must submit the bond to the Regional 
Administrator at least 60 days before the date on which hazardous waste 
is first received for disposal. The bond must be effective before this 
initial receipt of hazardous waste. The surety company issuing the bond 
must, at a minimum, be among those listed as acceptable sureties on 
Federal bonds in Circular 570 of the U.S. Department of the Treasury.
    (2) The wording of the surety bond must be identical to the wording 
specified in Sec. 264.151(c).
    (3) The owner or operator who uses a surety bond to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the bond, all payments made thereunder will be 
deposited by the surety directly into the standby trust fund in 
accordance with instructions from the Regional Administrator. This 
standby trust fund must meet the requirements specified in 
Sec. 264.145(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the surety bond; and
    (ii) Unless the standby trust fund is funded pursuant to the 
requirements of

[[Page 209]]

this section, the following are not required by these regulations:
    (A) Payments into the trust fund as specified in Sec. 264.145(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current post-closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The bond must guarantee that the owner or operator will:
    (i) Perform post-closure care in accordance with the post-closure 
plan and other requirements of the permit for the facility; or
    (ii) Provide alternate financial assurance as specified in this 
section, and obtain the Regional Administrator's written approval of the 
assurance provided, within 90 days of receipt by both the owner or 
operator and the Regional Administrator of a notice of cancellation of 
the bond from the surety.
    (5) Under the terms of the bond, the surety will become liable on 
the bond obligation when the owner or operator fails to perform as 
guaranteed by the bond. Following a final administrative determination 
pursuant to section 3008 of RCRA that the owner or operator has failed 
to perform post-closure care in accordance with the approved post-
closure plan and other permit requirements, under the terms of the bond 
the surety will perform post-closure care in accordance with the post-
closure plan and other permit requirements or will deposit the amount of 
the penal sum into the standby trust fund.
    (6) The penal sum of the bond must be in an amount at least equal to 
the current post-closure cost estimate.
    (7) Whenever the current post-closure cost estimate increases to an 
amount greater than the penal sum during the operating life of the 
facility, the owner or operator, within 60 days after the increase, must 
either cause the penal sum to be increased to an amount at least equal 
to the current post-closure cost estimate and submit evidence of such 
increase to the Regional Administrator, or obtain other financial 
assurance as specified in this section. Whenever the current post-
closure cost estimate decreases during the operating life of the 
facility, the penal sum may be reduced to the amount of the current 
post-closure cost estimate following written approval by the Regional 
Administrator.
    (8) During the period of post-closure care, the Regional 
Administrator may approve a decrease in the penal sum if the owner or 
operator demonstrates to the Regional Administrator that the amount 
exceeds the remaining cost of post-closure care.
    (9) Under the terms of the bond, the surety may cancel the bond by 
sending notice of cancellation by certified mail to the owner or 
operator and to the Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (10) The owner or operator may cancel the bond if the Regional 
Administrator has given prior written consent. The Regional 
Administrator will provide such written consent when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.145(i).
    (11) The surety will not be liable for deficiencies in the 
performance of post-closure care by the owner or operator after the 
Regional Administrator releases the owner or operator from the 
requirements of this section in accordance with Sec. 264.145(i).
    (d) Post-closure letter of credit. (1) An owner or operator may 
satisfy the requirements of this section by obtaining an irrevocable 
standby letter of credit which conforms to the requirements of this 
paragraph and submitting the letter to the Regional Administrator. An 
owner or operator of a new facility must submit the letter of credit to 
the Regional Administrator at least 60 days before the date on which 
hazardous waste is first received for disposal. The letter of credit 
must be effective before this initial receipt of hazardous waste. The 
issuing institution must be an entity which has the authority to issue 
letters of credit and whose letter-

[[Page 210]]

of-credit operations are regulated and examined by a Federal or State 
agency.
    (2) The wording of the letter of credit must be identical to the 
wording specified in Sec. 264.151(d).
    (3) An owner or operator who uses a letter of credit to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the letter of credit, all amounts paid pursuant to a 
draft by the Regional Administrator will be deposited by the issuing 
institution directly into the standby trust fund in accordance with 
instructions from the Regional Administrator. This standby trust fund 
must meet the requirements of the trust fund specified in 
Sec. 264.145(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the letter of credit; and
    (ii) Unless the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:
    (A) Payments into the trust fund as specified in Sec. 264.145(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current post-closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The letter of credit must be accompanied by a letter from the 
owner or operator referring to the letter of credit by number, issuing 
institution, and date, and providing the following information: the EPA 
Identification Number, name, and address of the facility, and the amount 
of funds assured for post-closure care of the facility by the letter of 
credit.
    (5) The letter of credit must be irrevocable and issued for a period 
of at least 1 year. The letter of credit must provide that the 
expiration date will be automatically extended for a period of at least 
1 year unless, at least 120 days before the current expiration date, the 
issuing institution notifies both the owner or operator and the Regional 
Administrator by certified mail of a decision not to extend the 
expiration date. Under the terms of the letter of credit, the 120 days 
will begin on the date when both the owner or operator and the Regional 
Administrator have received the notice, as evidenced by the return 
receipts.
    (6) The letter of credit must be issued in a amount at least equal 
to the current post-closure cost estimate, except as provided in 
Sec. 264.145(g).
    (7) Whenever the current post-closure cost estimate increases to an 
amount greater than the amount of the credit during the operating life 
of the facility, the owner or operator, within 60 days after the 
increase, must either cause the amount of the credit to be increased so 
that it at least equals the current post-closure cost estimate and 
submit evidence of such increase to the Regional Administrator, or 
obtain other financial assurance as specified in this section to cover 
the increase. Whenever the current post-closure cost estimate decreases 
during the operating life of the facility, the amount of the credit may 
be reduced to the amount of the current post-closure cost estimate 
following written approval by the Regional Administrator.
    (8) During the period of post-closure care, the Regional 
Administrator may approve a decrease in the amount of the letter of 
credit if the owner or operator demonstrates to the Regional 
Administrator that the amount exceeds the remaining cost of post-closure 
care.
    (9) Following a final administrative determination pursuant to 
section 3008 of RCRA that the owner or operator has failed to perform 
post-closure care in accordance with the approved post-closure plan and 
other permit requirements, the Regional Administrator may draw on the 
letter of credit.
    (10) If the owner or operator does not establish alternate financial 
assurance as specified in this section and obtain written approval of 
such alternate assurance from the Regional Administrator within 90 days 
after receipt by both the owner or operator and the Regional 
Administrator of a notice from the issuing institution that it has 
decided not to extend the letter of credit beyond the current expiration 
date, the Regional Administrator will draw on the letter of credit. The 
Regional Administrator may delay the drawing if

[[Page 211]]

the issuing institution grants an extension of the term of the credit. 
During the last 30 days of any such extension the Regional Administrator 
will draw on the letter of credit if the owner or operator has failed to 
provide alternate financial assurance as specified in this section and 
obtain written approval of such assurance from the Regional 
Administrator.
    (11) The Regional Administrator will return the letter of credit to 
the issuing institution for termination when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.145(i).
    (e) Post-closure insurance. (1) An owner or operator may satisfy the 
requirements of this section by obtaining post-closure insurance which 
conforms to the requirements of this paragraph and submitting a 
certificate of such insurance to the Regional Administrator. An owner or 
operator of a new facility must submit the certificate of insurance to 
the Regional Administrator at least 60 days before the date on which 
hazardous waste is first received for disposal. The insurance must be 
effective before this initial receipt of hazardous waste. At a minimum, 
the insurer must be licensed to transact the business of insurance, or 
eligible to provide insurance as an excess or surplus lines insurer, in 
one or more States.
    (2) The wording of the certificate of insurance must be identical to 
the wording specified in Sec. 264.151(e).
    (3) The post-closure insurance policy must be issued for a face 
amount at least equal to the current post-closure cost estimate, except 
as provided in Sec. 264.145(g). The term ``face amount'' means the total 
amount the insurer is obligated to pay under the policy. Actual payments 
by the insurer will not change the face amount, although the insurer's 
future liability will be lowered by the amount of the payments.
    (4) The post-closure insurance policy must guarantee that funds will 
be available to provide post-closure care of the facility whenever the 
post-closure period begins. The policy must also guarantee that once 
post-closure care begins, the insurer will be responsible for paying out 
funds, up to an amount equal to the face amount of the policy, upon the 
direction of the Regional Administrator, to such party or parties as the 
Regional Administrator specifies.
    (5) An owner or operator or any other person authorized to conduct 
post-closure care may request reimbursements for post-closure care 
expenditures by submitting itemized bills to the Regional Administrator. 
Within 60 days after receiving bills for post-closure care activities, 
the Regional Administrator will instruct the insurer to make 
reimbursements in those amounts as the Regional Administrator specifies 
in writing, if the Regional Administrator determines that the post-
closure care expenditures are in accordance with the approved post-
closure plan or otherwise justified. If the Regional Administrator does 
not instruct the insurer to make such reimbursements, he will provide 
the owner or operator with a detailed written statement of reasons.
    (6) The owner or operator must maintain the policy in full force and 
effect until the Regional Administrator consents to termination of the 
policy by the owner or operator as specified in paragraph (e)(11) of 
this section. Failure to pay the premium, without substitution of 
alternate financial assurance as specified in this section, will 
constitute a significant violation of these regulations, warranting such 
remedy as the Regional Administrator deems necessary. Such violation 
will be deemed to begin upon receipt by the Regional Administrator of a 
notice of future cancellation, termination, or failure to renew due to 
nonpayment of the premium, rather than upon the date of expiration.
    (7) Each policy must contain a provision allowing assignment of the 
policy to a successor owner or operator. Such assignment may be 
conditional upon consent of the insurer, provided such consent is not 
unreasonably refused.
    (8) The policy must provide that the insurer may not cancel, 
terminate, or fail to renew the policy except for failure to pay the 
premium. The automatic renewal of the policy must, at a

[[Page 212]]

minimum, provide the insured with the option of renewal at the face 
amount of the expiring policy. If there is a failure to pay the premium, 
the insurer may elect to cancel, terminate, or fail to renew the policy 
by sending notice by certified mail to the owner or operator and the 
Regional Administrator. Cancellation, termination, or failure to renew 
may not occur, however, during the 120 days beginning with the date of 
receipt of the notice by both the Regional Administrator and the owner 
or operator, as evidenced by the return receipts. Cancellation, 
termination, or failure to renew may not occur and the policy will 
remain in full force and effect in the event that on or before the date 
of expiration:
    (i) The Regional Administrator deems the facility abandoned; or
    (ii) The permit is terminated or revoked or a new permit is denied; 
or
    (iii) Closure is ordered by the Regional Administrator or a U.S. 
district court or other court of competent jurisdiction; or
    (iv) The owner or operator is named as debtor in a voluntary or 
involuntary proceeding under Title 11 (Bankruptcy), U.S. Code; or
    (v) The premium due is paid.
    (9) Whenever the current post-closure cost estimate increases to an 
amount greater than the face amount of the policy during the operating 
life of the facility, the owner or operator, within 60 days after the 
increase, must either cause the face amount to be increased to an amount 
at least equal to the current post-closure cost estimate and submit 
evidence of such increase to the Regional Administrator, or obtain other 
financial assurance as specified in this section to cover the increase. 
Whenever the current post-closure cost estimate decreases during the 
operating life of the facility, the face amount may be reduced to the 
amount of the current post-closure cost estimate following written 
approval by the Regional Administrator.
    (10) Commencing on the date that liability to make payments pursuant 
to the policy accrues, the insurer will thereafter annually increase the 
face amount of the policy. Such increase must be equivalent to the face 
amount of the policy, less any payments made, multiplied by an amount 
equivalent to 85 percent of the most recent investment rate or of the 
equivalent coupon-issue yield announced by the U.S. Treasury for 26-week 
Treasury securities.
    (11) The Regional Administrator will give written consent to the 
owner or operator that he may terminate the insurance policy when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.145(i).
    (f) Financial test and corporate guarantee for post-closure care. 
(1) An owner or operator may satisfy the requirements of this section by 
demonstrating that he passes a financial test as specified in this 
paragraph. To pass this test the owner or operator must meet the 
criteria of either paragraph (f)(1)(i) or (ii) of this section:
    (i) The owner or operator must have:
    (A) Two of the following three ratios: a ratio of total liabilities 
to net worth less than 2.0; a ratio of the sum of net income plus 
depreciation, depletion, and amortization to total liabilities greater 
than 0.1; and a ratio of current assets to current liabilities greater 
than 1.5; and
    (B) Net working capital and tangible net worth each at least six 
times the sum of the current closure and post-closure cost estimates and 
the current plugging and abandonment cost estimates; and
    (C) Tangible net worth of at least $10 million; and
    (D) Assets in the United States amounting to at least 90 percent of 
his total assets or at least six times the sum of the current closure 
and post-closure cost estimates and the current plugging and abandonment 
cost estimates.
    (ii) The owner or operator must have:
    (A) A current rating for his most recent bond issuance of AAA, AA, 
A, or BBB as issued by Standard and Poor's or Aaa, Aa, A or Baa as 
issued by Moody's; and
    (B) Tangible net worth at least six times the sum of the current 
closure and post-closure cost estimates and the

[[Page 213]]

current plugging and abandonment cost estimates; and
    (C) Tangible net worth of at least $10 million; and
    (D) Assets located in the United States amounting to at least 90 
percent of his total assets or at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates.
    (2) The phrase ``current closure and post-closure cost estimates'' 
as used in paragraph (f)(1) of this section refers to the cost estimates 
required to be shown in paragraphs 1-4 of the letter from the owner's or 
operator's chief financial officer (Sec. 264.151(f)). The phrase 
``current plugging and abandonment cost estimates'' as used in paragraph 
(f)(1) of this section refers to the cost estimates required to be shown 
in paragraphs 1-4 of the letter from the owner's or operator's chief 
financial officer (Sec. 144.70(f) of this title).
    (3) To demonstrate that he meets this test, the owner or operator 
must submit the following items to the Regional Administrator:
    (i) A letter signed by the owner's or operator's chief financial 
officer and worded as specified in Sec. 264.151(f); and
    (ii) A copy of the independent certified public accountant's report 
on examination of the owner's or operator's financial statements for the 
latest completed fiscal year; and
    (iii) A special report from the owner's or operator's independent 
certified public accountant to the owner or operator stating that:
    (A) He has compared the data which the letter from the chief 
financial officer specifies as having been derived from the 
independently audited, year-end financial statements for the latest 
fiscal year with the amounts in such financial statements; and
    (B) In connection with that procedure, no matters came to his 
attention which caused him to believe that the specified data should be 
adjusted.
    (4) An owner or operator of a new facility must submit the items 
specified in paragraph (f)(3) of this section to the Regional 
Administrator at least 60 days before the date on which hazardous waste 
is first received for disposal.
    (5) After the initial submission of items specified in paragraph 
(f)(3) of this section, the owner or operator must send updated 
information to the Regional Administrator within 90 days after the close 
of each succeeding fiscal year. This information must consist of all 
three items specified in paragraph (f)(3) of this section.
    (6) If the owner or operator no longer meets the requirements of 
paragraph (f)(1) of this section, he must send notice to the Regional 
Administrator of intent to establish alternate financial assurance as 
specified in this section. The notice must be sent by certified mail 
within 90 days after the end of the fiscal year for which the year-end 
financial data show that the owner or operator no longer meets the 
requirements. The owner or operator must provide the alternate financial 
assurance within 120 days after the end of such fiscal year.
    (7) The Regional Administrator may, based on a reasonable belief 
that the owner or operator may no longer meet the requirements of 
paragraph (f)(1) of this section, require reports of financial condition 
at any time from the owner or operator in addition to those specified in 
paragraph (f)(3) of this section. If the Regional Administrator finds, 
on the basis of such reports or other information, that the owner or 
operator no longer meets the requirements of paragraph (f)(1) of this 
section, the owner or operator must provide alternate financial 
assurance as specified in this section within 30 days after notification 
of such a finding.
    (8) The Regional Administrator may disallow use of this test on the 
basis of qualifications in the opinion expressed by the independent 
certified public accountant in his report on examination of the owner's 
or operator's financial statements (see paragraph (f)(3)(ii) of this 
section). An adverse opinion or a disclaimer of opinion will be cause 
for disallowance. The Regional Administrator will evaluate other 
qualifications on an individual basis. The owner or operator must 
provide alternate financial assurance as specified in this section 
within 30 days after notification of the disallowance.
    (9) During the period of post-closure care, the Regional 
Administrator may

[[Page 214]]

approve a decrease in the current post-closure cost estimate for which 
this test demonstrates financial assurance if the owner or operator 
demonstrates to the Regional Administrator that the amount of the cost 
estimate exceeds the remaining cost of post-closure care.
    (10) The owner or operator is no longer required to submit the items 
specified in paragraph (f)(3) of this section when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 264.145(i).
    (11) An owner or operator may meet the requirements for this section 
by obtaining a written guarantee. The guarantor must be the direct of 
higher-tier parent corporation of the owner or operator, a firm whose 
parent corporation is also the parent corporation of the owner or 
operator, or a firm with a ``substantial business relationship'' with 
the owner or operator. The guarantor must meet the requirements for 
owners or operators in paragraphs (f)(1) through (9) of this section and 
must comply with the terms of the guarantee. The wording of the 
guarantee must be identical to the wording specified in Sec. 264.151(h). 
A certified copy of the guarantee must accompany the items sent to the 
Regional Administrator as specified in paragraph (f)(3) of this section. 
One of these items must be the letter from the guarantor's chief 
financial officer. If the guarantor's parent corporation is also the 
parent corporation of the owner or operator, the letter must describe 
the value received in consideration of the guarantee. If the guarantor 
is a firm with a ``substantial business relationship'' with the owner or 
operator, this letter must describe this ``substantial business 
relationship'' and the value received in consideration of the guarantee. 
The terms of the guarantee must provide that:
    (i) If the owner or operator fails to perform post-closure care of a 
facility covered by the corporate guarantee in accordance with the post-
closure plan and other permit requirements whenever required to do so, 
the guarantor will do so or establish a trust fund as specified in 
Sec. 264.145(a) in the name of the owner or operator.
    (ii) The corporate guarantee will remain in force unless the 
guarantor sends notice of cancellation by certified mail to the owner or 
operator and to the Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (iii) If the owner or operator fails to provide alternate financial 
assurance as specified in this section and obtain the written approval 
of such alternate assurance from the Regional Administrator within 90 
days after receipt by both the owner or operator and the Regional 
Administrator of a notice of cancellation of the corporate guarantee 
from the guarantor, the guarantor will provide such alternate financial 
assurance in the name of the owner or operator.
    (g) Use of multiple financial mechanisms. An owner or operator may 
satisfy the requirements of this section by establishing more than one 
financial mechanism per facility. These mechanisms are limited to trust 
funds, surety bonds guaranteeing payment into a trust fund, letters of 
credit, and insurance. The mechanisms must be as specified in paragraphs 
(a), (b), (d), and (e), respectively, of this section, except that it is 
the combination of mechanisms, rather than the single mechanism, which 
must provide financial assurance for an amount at least equal to the 
current post-closure cost estimate. If an owner or operator uses a trust 
fund in combination with a surety bond or a letter of credit, he may use 
the trust fund as the standby trust fund for the other mechanisms. A 
single standby trust fund may be established for two or more mechanisms. 
The Regional Administrator may use any or all of the mechanisms to 
provide for post-closure care of the facility.
    (h) Use of a financial mechanism for multiple facilities. An owner 
or operator may use a financial assurance mechanism specified in this 
section to meet the requirements of this section for

[[Page 215]]

more than one facility. Evidence of financial assurance submitted to the 
Regional Administrator must include a list showing, for each facility, 
the EPA Identification Number, name, address, and the amount of funds 
for post-closure care assured by the mechanism. If the facilities 
covered by the mechanism are in more than one Region, identical evidence 
of financial assurance must be submitted to and maintained with the 
Regional Administrators of all such Regions. The amount of funds 
available through the mechanism must be no less than the sum of funds 
that would be available if a separate mechanism had been established and 
maintained for each facility. In directing funds available through the 
mechanism for post-closure care of any of the facilities covered by the 
mechanism, the Regional Administrator may direct only the amount of 
funds designated for that facility, unless the owner or operator agrees 
to the use of additional funds available under the mechanism.
    (i) Release of the owner or operator from the requirements of this 
section. Within 60 days after receiving certifications from the owner or 
operator and an independent registered professional engineer that the 
post-closure care period has been completed for a hazardous waste 
disposal unit in accordance with the approved plan, the Regional 
Administrator will notify the owner or operator that he is no longer 
required to maintain financial assurance for post-closure care of that 
unit, unless the Regional Administrator has reason to believe that post-
closure care has not been in accordance with the approved post-closure 
plan. The Regional Administrator shall provide the owner or operator 
with a detailed written statement of any such reason to believe that 
post-closure care has not been in accordance with the approved post-
closure plan.

[47 FR 15047, Apr. 7, 1982, as amended at 51 FR 16449, May 2, 1986; 57 
FR 42836, Sept. 16, 1992]



Sec. 264.146  Use of a mechanism for financial assurance of both closure and post-closure care.

    An owner or operator may satisfy the requirements for financial 
assurance for both closure and post-closure care for one or more 
facilities by using a trust fund, surety bond, letter of credit, 
insurance, financial test, or corporate guarantee that meets the 
specifications for the mechanism in both Secs. 264.143 and 264.145. The 
amount of funds available through the mechanism must be no less than the 
sum of funds that would be available if a separate mechanism had been 
established and maintained for financial assurance of closure and of 
post-closure care.



Sec. 264.147  Liability requirements.

    (a) Coverage for sudden accidental occurrences. An owner or operator 
of a hazardous waste treatment, storage, or disposal facility, or a 
group of such facilities, must demonstrate financial responsibility for 
bodily injury and property damage to third parties caused by sudden 
accidental occurrences arising from operations of the facility or group 
of facilities. The owner or operator must have and maintain liability 
coverage for sudden accidental occurrences in the amount of at least $1 
million per occurrence with an annual aggregate of at least $2 million, 
exclusive of legal defense costs. This liability coverage may be 
demonstrated as specified in paragraphs (a) (1), (2), (3), (4), (5), or 
(6) of this section:
    (1) An owner or operator may demonstrate the required liability 
coverage by having liability insurance as specified in this paragraph.
    (i) Each insurance policy must be amended by attachment of the 
Hazardous Waste Facility Liability Endorsement or evidenced by a 
Certificate of Liability Insurance. The wording of the endorsement must 
be identical to the wording specified in Sec. 264.151(i). The wording of 
the certificate of insurance must be identical to the wording specified 
in Sec. 264.151(j). The owner or operator must submit a signed duplicate 
original of the endorsement or the certificate of insurance to the 
Regional Administrator, or Regional Administrators if the facilities are 
located in more than one Region. If requested by a Regional 
Administrator, the owner or operator must provide a signed duplicate 
original of the insurance policy. An owner or operator of a new facility

[[Page 216]]

must submit the signed duplicate original of the Hazardous Waste 
Facility Liability Endorsement or the Certificate of Liability Insurance 
to the Regional Administrator at least 60 days before the date on which 
hazardous waste is first received for treatment, storage, or disposal. 
The insurance must be effective before this initial receipt of hazardous 
waste.
    (ii) Each insurance policy must be issued by an insurer which, at a 
minimum, is licensed to transact the business of insurance, or eligible 
to provide insurance as an excess or surplus lines insurer, in one or 
more States.
    (2) An owner or operator may meet the requirements of this section 
by passing a financial test or using the guarantee for liability 
coverage as specified in paragraphs (f) and (g) of this section.
    (3) An owner or operator may meet the requirements of this section 
by obtaining a letter of credit for liability coverage as specified in 
paragraph (h) of this section.
    (4) An owner or operator may meet the requirements of this section 
by obtaining a surety bond for liability coverage as specified in 
paragraph (i) of this section.
    (5) An owner or operator may meet the requirements of this section 
by obtaining a trust fund for liability coverage as specified in 
paragraph (j) of this section.
    (6) An owner or operator may demonstrate the required liability 
coverage through the use of combinations of insurance, financial test, 
guarantee, letter of credit, surety bond, and trust fund, except that 
the owner or operator may not combine a financial test covering part of 
the liability coverage requirement with a guarantee unless the financial 
statement of the owner or operator is not consolidated with the 
financial statement of the guarantor. The amounts of coverage 
demonstrated must total at least the minimum amounts required by this 
section. If the owner or operator demonstrates the required coverage 
through the use of a combination of financial assurances under this 
paragraph, the owner or operator shall specify at least one such 
assurance as ``primary'' coverage and shall specify other assurance as 
``excess'' coverage.
    (7) An owner or operator shall notify the Regional Administrator in 
writing within 30 days whenever:
    (i) A claim results in a reduction in the amount of financial 
assurance for liability coverage provided by a financial instrument 
authorized in paragraphs (a)(1) through (a)(6) of this section; or
    (ii) A Certification of Valid Claim for bodily injury or property 
damages caused by a sudden or non-sudden accidental occurrence arising 
from the operation of a hazardous waste treatment, storage, or disposal 
facility is entered between the owner or operator and third-party 
claimant for liability coverage under paragraphs (a)(1) through (a)(6) 
of this section; or
    (iii) A final court order establishing a judgment for bodily injury 
or property damage caused by a sudden or non-sudden accidental 
occurrence arising from the operation of a hazardous waste treatment, 
storage, or disposal facility is issued against the owner or operator or 
an instrument that is providing financial assurance for liability 
coverage under paragraphs (a)(1) through (a)(6) of this section.
    (b) Coverage for nonsudden accidental occurrences. An owner or 
operator of a surface impoundment, landfill, land treatment facility, or 
disposal miscellaneous unit that is used to manage hazardous waste, or a 
group of such facilities, must demonstrate financial responsibility for 
bodily injury and property damage to third parties caused by nonsudden 
accidental occurrences arising from operations of the facility or group 
of facilities. The owner or operator must have and maintain liability 
coverage for nonsudden accidental occurrences in the amount of at least 
$3 million per occurrence with an annual aggregate of at least $6 
million, exclusive of legal defense costs. An owner or operator who must 
meet the requirements of this section may combine the required per-
occurrence coverage levels for sudden and nonsudden accidental 
occurrences into a single per-occurrence level, and combine the required 
annual aggregate coverage levels for

[[Page 217]]

sudden and nonsudden accidental occurrences into a single annual 
aggregate level. Owners or operators who combine coverage levels for 
sudden and nonsudden accidental occurrences must maintain liability 
coverage in the amount of at least $4 million per occurrence and $8 
million annual aggregate. This liability coverage may be demonstrated as 
specified in paragraphs (b) (1), (2), (3), (4), (5), or (6), of this 
section:
    (1) An owner or operator may demonstrate the required liability 
coverage by having liability insurance as specified in this paragraph.
    (i) Each insurance policy must be amended by attachment of the 
Hazardous Waste Facility Liability Endorsement or evidenced by a 
Certificate of Liability Insurance. The wording of the endorsement must 
be identical to the wording specified in Sec. 264.151(i). The wording of 
the certificate of insurance must be identical to the wording specified 
in Sec. 264.151(j). The owner or operator must submit a signed duplicate 
original of the endorsement or the certificate of insurance to the 
Regional Administrator, or Regional Administrators if the facilities are 
located in more than one Region. If requested by a Regional 
Administrator, the owner or operator must provide a signed duplicate 
original of the insurance policy. An owner or operator of a new facility 
must submit the signed duplicate original of the Hazardous Waste 
Facility Liability Endorsement or the Certificate of Liability Insurance 
to the Regional Administrator at least 60 days before the date on which 
hazardous waste is first received for treatment, storage, or disposal. 
The insurance must be effective before this initial receipt of hazardous 
waste.
    (ii) Each insurance policy must be issued by an insurer which, at a 
minimum, is licensed to transact the business of insurance, or eligible 
to provide insurance as an excess or surplus lines insurer, in one or 
more States.
    (2) An owner or operator may meet the requirements of this section 
by passing a financial test or using the guarantee for liability 
coverage as specified in paragraphs (f) and (g) of this section.
    (3) An owner or operator may meet the requirements of this section 
by obtaining a letter of credit for liability coverage as specified in 
paragraph (h) of this section.
    (4) An owner or operator may meet the requirements of this section 
by obtaining a surety bond for liability coverage as specified in 
paragraph (i) of this section.
    (5) An owner or operator may meet the requirements of this section 
by obtaining a trust fund for liability coverage as specified in 
paragraph (j) of this section.
    (6) An owner or operator may demonstrate the required liability 
coverage through the use of combinations of insurance, financial test, 
guarantee, letter of credit, surety bond, and trust fund, except that 
the owner or operator may not combine a financial test covering part of 
the liability coverage requirement with a guarantee unless the financial 
statement of the owner or operator is not consolidated with the 
financial statement of the guarantor. The amounts of coverage 
demonstrated must total at least the minimum amount required by this 
section. If the owner or operator demonstrates the required coverage 
through the use of a combination of financial assurances under this 
paragraph, the owner or operator shall specify at least one such 
assurance as ``primary'' coverage and shall specify other assurance as 
``excess'' coverage.
    (7) An owner or operator shall notify the Regional Administrator in 
writing within 30 days whenever:
    (i) A Claim results in a reduction in the amount of financial 
assurance for liability coverage provided by a financial instrument 
authorized in paragraphs (b)(1) through (b)(6) of this section; or
    (ii) A Certification of Valid Claim for bodily injury or property 
damages caused by a sudden or non-sudden accidental occurrence arising 
from the operation of a hazardous waste treatment, storage, or disposal 
facility is entered between the owner or operator and third-party 
claimant for liability coverage under paragraphs (b)(1) through (b)(6) 
of this section; or
    (iii) A final court order establishing a judgment for bodily injury 
or property

[[Page 218]]

damage caused by a sudden or non-sudden accidental occurrence arising 
from the operation of a hazardous waste treatment, storage, or disposal 
facility is issued against the owner or operator or an instrument that 
is providing financial assurance for liability coverage under paragraphs 
(b)(1) through (b)(6) of this section.
    (c) Request for variance. If an owner or operator can demonstrate to 
the satisfaction of the Regional Administrator that the levels of 
financial responsibility required by paragraph (a) or (b) of this 
section are not consistent with the degree and duration of risk 
associated with treatment, storage, or disposal at the facility or group 
of facilities, the owner or operator may obtain a variance from the 
Regional Administrator. The request for a variance must be submitted to 
the Regional Administrator as part of the application under Sec. 270.14 
of this chapter for a facility that does not have a permit, or pursuant 
to the procedures for permit modification under Sec. 124.5 of this 
chapter for a facility that has a permit. If granted, the variance will 
take the form of an adjusted level of required liability coverage, such 
level to be based on the Regional Administrator's assessment of the 
degree and duration of risk associated with the ownership or operation 
of the facility or group of facilities. The Regional Administrator may 
require an owner or operator who requests a variance to provide such 
technical and engineering information as is deemed necessary by the 
Regional Administrator to determine a level of financial responsibility 
other than that required by paragraph (a) or (b) of this section. Any 
request for a variance for a permitted facility will be treated as a 
request for a permit modification under Secs. 270.41(a)(5) and 124.5 of 
this chapter.
    (d) Adjustments by the Regional Administrator. If the Regional 
Administrator determines that the levels of financial responsibility 
required by paragraph (a) or (b) of this section are not consistent with 
the degree and duration of risk associated with treatment, storage, or 
disposal at the facility or group of facilities, the Regional 
Administrator may adjust the level of financial responsibility required 
under paragraph (a) or (b) of this section as may be necessary to 
protect human health and the environment. This adjusted level will be 
based on the Regional Administrator's assessment of the degree and 
duration of risk associated with the ownership or operation of the 
facility or group of facilities. In addition, if the Regional 
Administrator determines that there is a significant risk to human 
health and the environment from nonsudden accidental occurrences 
resulting from the operations of a facility that is not a surface 
impoundment, landfill, or land treatment facility, he may require that 
an owner or operator of the facility comply with paragraph (b) of this 
section. An owner or operator must furnish to the Regional 
Administrator, within a reasonable time, any information which the 
Regional Administrator requests to determine whether cause exists for 
such adjustments of level or type of coverage. Any adjustment of the 
level or type of coverage for a facility that has a permit will be 
treated as a permit modification under Secs. 270.41(a)(5) and 124.5 of 
this chapter.
    (e) Period of coverage. Within 60 days after receiving 
certifications from the owner or operator and an independent registered 
professional engineer that final closure has been completed in 
accordance with the approved closure plan, the Regional Administrator 
will notify the owner or operator in writing that he is no longer 
required by this section to maintain liability coverage for that 
facility, unless the Regional Administrator has reason to believe that 
closure has not been in accordance with the approved closure plan.
    (f) Financial test for liability coverage. (1) An owner or operator 
may satisfy the requirements of this section by demonstrating that he 
passes a financial test as specified in this paragraph. To pass this 
test the owner or operator must meet the criteria of paragraph (f)(1)(i) 
or (ii):
    (i) The owner or operator must have:
    (A) Net working capital and tangible net worth each at least six 
times the amount of liability coverage to be demonstrated by this test; 
and
    (B) Tangible net worth of at least $10 million; and

[[Page 219]]

    (C) Assets in the United States amounting to either: (1) At least 90 
percent of his total assets; or (2) at least six times the amount of 
liability coverage to be demonstrated by this test.
    (ii) The owner or operator must have:
    (A) A current rating for his most recent bond issuance of AAA, AA, 
A, or BBB as issued by Standard and Poor's, or Aaa, Aa, A, or Baa as 
issued by Moody's; and
    (B) Tangible net worth of at least $10 million; and
    (C) Tangible net worth at least six times the amount of liability 
coverage to be demonstrated by this test; and
    (D) Assets in the United States amounting to either: (1) At least 90 
percent of his total assets; or (2) at least six times the amount of 
liability coverage to be demonstrated by this test.
    (2) The phrase ``amount of liability coverage'' as used in paragraph 
(f)(1) of this section refers to the annual aggregate amounts for which 
coverage is required under paragraphs (a) and (b) of this section.
    (3) To demonstrate that he meets this test, the owner or operator 
must submit the following three items to the Regional Administrator:
    (i) A letter signed by the owner's or operator's chief financial 
officer and worded as specified in Sec. 264.151(g). If an owner or 
operator is using the financial test to demonstrate both assurance for 
closure or post-closure care, as specified by Secs. 264.143(f), 
264.145(f), 265.143(e), and 265.145(e), and liability coverage, he must 
submit the letter specified in Sec. 264.151(g) to cover both forms of 
financial responsibility; a separate letter as specified in 
Sec. 264.151(f) is not required.
    (ii) A copy of the independent certified public accountant's report 
on examination of the owner's or operator's financial statements for the 
latest completed fiscal year.
    (iii) A special report from the owner's or operator's independent 
certified public accountant to the owner or operator stating that:
    (A) He has compared the data which the letter from the chief 
financial officer specifies as having been derived from the 
independently audited, year-end financial statements for the latest 
fiscal year with the amounts in such financial statements; and
    (B) In connection with that procedure, no matters came to his 
attention which caused him to believe that the specified data should be 
adjusted.
    (4) An owner or operator of a new facility must submit the items 
specified in paragraph (f)(3) of this section to the Regional 
Administrator at least 60 days before the date on which hazardous waste 
is first received for treatment, storage, or disposal.
    (5) After the initial submission of items specified in paragraph 
(f)(3) of this section, the owner or operator must send updated 
information to the Regional Administrator within 90 days after the close 
of each succeeding fiscal year. This information must consist of all 
three items specified in paragraph (f)(3) of this section.
    (6) If the owner or operator no longer meets the requirements of 
paragraph (f)(1) of this section, he must obtain insurance, a letter of 
credit, a surety bond, a trust fund, or a guarantee for the entire 
amount of required liability coverage as specified in this section. 
Evidence of liability coverage must be submitted to the Regional 
Administrator within 90 days after the end of the fiscal year for which 
the year-end financial data show that the owner or operator no longer 
meets the test requirements.
    (7) The Regional Administrator may disallow use of this test on the 
basis of qualifications in the opinion expressed by the independent 
certified public accountant in his report on examination of the owner's 
or operator's financial statements (see paragraph (f)(3)(ii) of this 
section). An adverse opinion or a disclaimer of opinion will be cause 
for disallowance. The Regional Administrator will evaluate other 
qualifications on an individual basis. The owner or operator must 
provide evidence of insurance for the entire amount of required 
liability coverage as specified in this section within 30 days after 
notification of disallowance.
    (g) Guarantee for liability coverage. (1) Subject to paragraph 
(g)(2) of this section, an owner or operator may meet the requirements 
of this section by obtaining a written guarantee, hereinafter referred 
to as ``guarantee.'' The guarantor must be the direct or higher-tier 
parent corporation of the owner or

[[Page 220]]

operator, a firm whose parent corporation is also the parent corporation 
of the owner or operator, or a firm with a ``substantial business 
relationship'' with the owner or operator. The guarantor must meet the 
requirements for owners or operators in paragraphs (f)(1) through (f)(6) 
of this section. The wording of the guarantee must be identical to the 
wording specified in Sec. 264.151(h)(2) of this part. A certified copy 
of the guarantee must accompany the items sent to the Regional 
Administrator as specified in paragraph (f)(3) of this section. One of 
these items must be the letter from the guarantor's chief financial 
officer. If the guarantor's parent corporation is also the parent 
corporation of the owner or operator, this letter must describe the 
value received in consideration of the guarantee. If the guarantor is a 
firm with a ``substantial business relationship'' with the owner or 
operator, this letter must describe this ``substantial business 
relationship'' and the value received in consideration of the guarantee.
    (i) If the owner or operator fails to satisfy a judgment based on a 
determination of liability for bodily injury or property damage to third 
parties caused by sudden or nonsudden accidental occurrences (or both as 
the case may be), arising from the operation of facilities covered by 
this corporate guarantee, or fails to pay an amount agreed to in 
settlement of claims arising from or alleged to arise from such injury 
or damage, the guarantor will do so up to the limits of coverage.
    (ii) [Reserved]
    (2)(i) In the case of corporations incorporated in the United 
States, a guarantee may be used to satisfy the requirements of this 
section only if the Attorneys General or Insurance Commissioners of (A) 
the State in which the guarantor is incorporated, and (B) each State in 
which a facility covered by the guarantee is located have submitted a 
written statement to EPA that a guarantee executed as described in this 
section and Sec. 264.151(h)(2) is a legally valid and enforceable 
obligation in that State.
    (ii) In the case of corporations incorporated outside the United 
States, a guarantee may be used to satisfy the requirements of this 
section only if (A) the non-U.S. corporation has identified a registered 
agent for service of process in each State in which a facility covered 
by the guarantee is located and in the State in which it has its 
principal place of business, and (B) the Attorney General or Insurance 
Commissioner of each State in which a facility covered by the guarantee 
is located and the State in which the guarantor corporation has its 
principal place of business, has submitted a written statement to EPA 
that a guarantee executed as described in this section and 
Sec. 264.151(h)(2) is a legally valid and enforceable obligation in that 
State.
    (h) Letter of credit for liability coverage. (1) An owner or 
operator may satisfy the requirements of this section by obtaining an 
irrevocable standby letter or credit that conforms to the requirements 
of this paragraph and submitting a copy of the letter of credit to the 
Regional Administrator.
    (2) The financial institution issuing the letter of credit must be 
an entity that has the authority to issue letters of credit and whose 
letter of credit operations are regulated and examined by a Federal or 
State agency.
    (3) The wording of the letter of credit must be identical to the 
wording specified in Sec. 264.151(k) of this part.
    (4) An owner or operator who uses a letter of credit to satisfy the 
requirements of this section may also establish a standby trust fund. 
Under the terms of such a letter of credit, all amounts paid pursuant to 
a draft by the trustee of the standby trust will be deposited by the 
issuing institution into the standby trust in accordance with 
instructions from the trustee. The trustee of the standby trust fund 
must be an entity which has the authority to act as a trustee and whose 
trust operations are regulated and examined by a Federal or State 
agency.
    (5) The wording of the standby trust fund must be identical to the 
wording specified in Sec. 264.151(n).
    (i) Surety bond for liability coverage. (1) An owner or operator may 
satisfy the requirements of this section by obtaining a surety bond that 
conforms to the requirements of this paragraph and submitting a copy of 
the bond to the Regional Administrator.

[[Page 221]]

    (2) The surety company issuing the bond must be among those listed 
as acceptable sureties on Federal bonds in the most recent Circular 570 
of the U.S. Department of the Treasury.
    (3) The wording of the surety bond must be identical to the wording 
specified in Sec. 264.151(l) of this part.
    (4) A surety bond may be used to satisfy the requirements of this 
section only if the Attorneys General or Insurance Commissioners of (i) 
the State in which the surety is incorporated, and (ii) each State in 
which a facility covered by the surety bond is located have submitted a 
written statement to EPA that a surety bond executed as described in 
this section and Sec. 264.151(l) of this part is a legally valid and 
enforceable obligation in that State.
    (j) Trust fund for liability coverage. (1) An owner or operator may 
satisfy the requirements of this section by establishing a trust fund 
that conforms to the requirements of this paragraph and submitting an 
originally signed duplicate of the trust agreement to the Regional 
Administrator.
    (2) The trustee must be an entity which has the authority to act as 
a trustee and whose trust operations are regulated and examined by a 
Federal or State agency.
    (3) The trust fund for liability coverage must be funded for the 
full amount of the liability coverage to be provided by the trust fund 
before it may be relied upon to satisfy the requirements of this 
section. If at any time after the trust fund is created the amount of 
funds in the trust fund is reduced below the full amount of the 
liability coverage to be provided, the owner or operator, by the 
anniversary date of the establishment of the fund, must either add 
sufficient funds to the trust fund to cause its value to equal the full 
amount of liability coverage to be provided, or obtain other financial 
assurance as specified in this section to cover the difference. For 
purposes of this paragraph, ``the full amount of the liability coverage 
to be provided'' means the amount of coverage for sudden and/or 
nonsudden occurrences required to be provided by the owner or operator 
by this section, less the amount of financial assurance for liability 
coverage that is being provided by other financial assurance mechanisms 
being used to demonstrate financial assurance by the owner or operator.
    (4) The wording of the trust fund must be identical to the wording 
specified in Sec. 264.151(m) of this part.
    (k) Notwithstanding any other provision of this part, an owner or 
operator using liability insurance to satisfy the requirements of this 
section may use, until October 16, 1982, a Hazardous Waste Facility 
Liability Endorsement or Certificate of Liability Insurance that does 
not certify that the insurer is licensed to transact the business of 
insurance, or eligible as an excess or surplus lines insurer, in one or 
more States.

Sec. 264.148  Incapacity of owners or operators, guarantors, or financial institutions.

    (a) An owner or operator must notify the Regional Administrator by 
certified mail of the commencement of a voluntary or involuntary 
proceeding under Title 11 (Bankruptcy), U.S. Code, naming the owner or 
operator as debtor, within 10 days after commencement of the proceeding. 
A guarantor of a corporate guarantee as specified in Secs. 264.143(f) 
and 264.145(f) must make such a notification if he is named as debtor, 
as required under the terms of the corporate guarantee 
(Sec. 264.151(h)).
    (b) An owner or operator who fulfills the requirements of 
Sec. 264.143, Sec. 264.145, or Sec. 264.147 by obtaining a trust fund, 
surety bond, letter of credit, or insurance policy will be deemed to be 
without the required financial assurance or liability coverage in the 
event of bankruptcy of the trustee or issuing institution, or a 
suspension or revocation of the authority of the trustee institution to 
act as trustee or of the institution issuing the surety bond, letter of 
credit, or insurance policy to issue such instruments. The owner or 
operator must establish other financial assurance or

[[Page 222]]

liability coverage within 60 days after such an event.



Sec. 264.149  Use of State-required mechanisms.

    (a) For a facility located in a State where EPA is administering the 
requirements of this subpart but where the State has hazardous waste 
regulations that include requirements for financial assurance of closure 
or post-closure care or liability coverage, an owner or operator may use 
State-required financial mechanisms to meet the requirements of 
Sec. 264.143, Sec. 264.145, or Sec. 264.147, if the Regional 
Administrator determines that the State mechanisms are at least 
equivalent to the financial mechanism specified in this subpart. The 
Regional Administrator will evaluate the equivalency of the mechanisms 
principally in terms of (1) certainty of the availability of funds for 
the required closure or post-closure care activities or liability 
coverage and (2) the amount of funds that will be made available. The 
Regional Administrator may also consider other factors as he deems 
appropriate. The owner or operator must submit to the Regional 
Administrator evidence of the establishment of the mechanism together 
with a letter requesting that the State-required mechanism be considered 
acceptable for meeting the requirements of this subpart. The submission 
must include the following information: The facility's EPA 
Identification Number, name, and address, and the amount of funds for 
closure or post-closure care or liability coverage assured by the 
mechanism. The Regional Administrator will notify the owner or operator 
of his determination regarding the mechanism's acceptability in lieu of 
financial mechanisms specified in this subpart. The Regional 
Administrator may require the owner or operator to submit additional 
information as is deemed necessary to make this determination. Pending 
this determination, the owner or operator will be deemed to be in 
compliance with the requirements of Sec. 264.143, Sec. 264.145, or 
Sec. 264.147, as applicable.
    (b) If a State-required mechanism is found acceptable as specified 
in paragraph (a) of this section except for the amount of funds 
available, the owner or operator may satisfy the requirements of this 
subpart by increasing the funds available through the State-required 
mechanism or using additional financial mechanisms as specified in this 
subpart. The amount of funds available through the State and Federal 
mechanisms must at least equal the amount required by this subpart.



Sec. 264.150  State assumption of responsibility.

    (a) If a State either assumes legal responsibility for an owner's or 
operator's compliance with the closure, post-closure care, or liability 
requirements of this part or assures that funds will be available from 
State sources to cover those requirements, the owner or operator will be 
in compliance with the requirements of Sec. 264.143, Sec. 264.145, or 
Sec. 264.147 if the Regional Administrator determines that the State's 
assumption of responsibility is at least equivalent to the financial 
mechanisms specified in this subpart. The Regional Administrator will 
evaluate the equivalency of State guarantees principally in terms of (1) 
certainty of the availability of funds for the required closure or post-
closure care activities or liability coverage and (2) the amount of 
funds that will be made available. The Regional Administrator may also 
consider other factors as he deems appropriate. The owner or operator 
must submit to the Regional Administrator a letter from the State 
describing the nature of the State's assumption of responsibility 
together with a letter from the owner or operator requesting that the 
State's assumption of responsibility be considered acceptable for 
meeting the requirements of this subpart. The letter from the State must 
include, or have attached to it, the following information: the 
facility's EPA Identification Number, name, and address, and the amount 
of funds for closure or post-closure care or liability coverage that are 
guaranteed by the State. The Regional Administrator will notify the 
owner or operator of his determination regarding the acceptability of 
the State's guarantee in lieu of financial mechanisms specified in this 
subpart. The Regional Administrator may require the owner or operator to 
submit additional information as

[[Page 223]]

is deemed necessary to make this determination. Pending this 
determination, the owner or operator will be deemed to be in compliance 
with the requirements of Sec. 264.143, Sec. 264.145, or Sec. 264.147, as 
applicable.
    (b) If a State's assumption of responsibility is found acceptable as 
specified in paragraph (a) of this section except for the amount of 
funds available, the owner or operator may satisfy the requirements of 
this subpart by use of both the State's assurance and additional 
financial mechanisms as specified in this subpart. The amount of funds 
available through the State and Federal mechanisms must at least equal 
the amount required by this subpart.



Sec. 264.151  Wording of the instruments.

    (a)(1) A trust agreement for a trust fund, as specified in 
Sec. 264.143(a) or Sec. 264.145(a) or Sec. 265.143(a) or Sec. 265.145(a) 
of this chapter, must be worded as follows, except that instructions in 
brackets are to be replaced with the relevant information and the 
brackets deleted:

                             Trust Agreement

    Trust Agreement, the ``Agreement,'' entered into as of [date] by and 
between [name of the owner or operator], a [name of State] [insert 
``corporation,'' ``partnership,'' ``association,'' or 
``proprietorship''], the ``Grantor,'' and [name of corporate trustee], 
[insert ``incorporated in the State of ----'' or ``a national bank''], 
the ``Trustee.''
    Whereas, the United States Environmental Protection Agency, ``EPA,'' 
an agency of the United States Government, has established certain 
regulations applicable to the Grantor, requiring that an owner or 
operator of a hazardous waste management facility shall provide 
assurance that funds will be available when needed for closure and/or 
post-closure care of the facility,
    Whereas, the Grantor has elected to establish a trust to provide all 
or part of such financial assurance for the facilities identified 
herein,
    Whereas, the Grantor, acting through its duly authorized officers, 
has selected the Trustee to be the trustee under this agreement, and the 
Trustee is willing to act as trustee,
    Now, Therefore, the Grantor and the Trustee agree as follows:
    Section 1. Definitions. As used in this Agreement:
    (a) The term ``Grantor'' means the owner or operator who enters into 
this Agreement and any successors or assigns of the Grantor.
    (b) The term ``Trustee'' means the Trustee who enters into this 
Agreement and any successor Trustee.
    Section 2. Identification of Facilities and Cost Estimates. This 
Agreement pertains to the facilities and cost estimates identified on 
attached Schedule A [on Schedule A, for each facility list the EPA 
Identification Number, name, address, and the current closure and/or 
post-closure cost estimates, or portions thereof, for which financial 
assurance is demonstrated by this Agreement].
    Section 3. Establishment of Fund. The Grantor and the Trustee hereby 
establish a trust fund, the ``Fund,'' for the benefit of EPA. The 
Grantor and the Trustee intend that no third party have access to the 
Fund except as herein provided. The Fund is established initially as 
consisting of the property, which is acceptable to the Trustee, 
described in Schedule B attached hereto. Such property and any other 
property subsequently transferred to the Trustee is referred to as the 
Fund, together with all earnings and profits thereon, less any payments 
or distributions made by the Trustee pursuant to this Agreement. The 
Fund shall be held by the Trustee, IN TRUST, as hereinafter provided. 
The Trustee shall not be responsible nor shall it undertake any 
responsibility for the amount or adequacy of, nor any duty to collect 
from the Grantor, any payments necessary to discharge any liabilities of 
the Grantor established by EPA.
    Section 4. Payment for Closure and Post-Closure Care. The Trustee 
shall make payments from the Fund as the EPA Regional Administrator 
shall direct, in writing, to provide for the payment of the costs of 
closure and/or post-closure care of the facilities covered by this 
Agreement. The Trustee shall reimburse the Grantor or other persons as 
specified by the EPA Regional Administrator from the Fund for closure 
and post-closure expenditures in such amounts as the EPA Regional 
Administrator shall direct in writing. In addition, the Trustee shall 
refund to the Grantor such amounts as the EPA Regional Administrator 
specifies in writing. Upon refund, such funds shall no longer constitute 
part of the Fund as defined herein.
    Section 5. Payments Comprising the Fund. Payments made to the 
Trustee for the Fund shall consist of cash or securities acceptable to 
the Trustee.
    Section 6. Trustee Management. The Trustee shall invest and reinvest 
the principal and income of the Fund and keep the Fund invested as a 
single fund, without distinction between principal and income, in 
accordance with general investment policies and guidelines which the 
Grantor may communicate in writing to the Trustee from time to time, 
subject, however, to the provisions of this section. In investing, 
reinvesting, exchanging, selling, and managing the Fund, the

[[Page 224]]

Trustee shall discharge his duties with respect to the trust fund solely 
in the interest of the beneficiary and with the care, skill, prudence, 
and diligence under the circumstances then prevailing which persons of 
prudence, acting in a like capacity and familiar with such matters, 
would use in the conduct of an enterprise of a like character and with 
like aims; except that:
    (i) Securities or other obligations of the Grantor, or any other 
owner or operator of the facilities, or any of their affiliates as 
defined in the Investment Company Act of 1940, as amended, 15 U.S.C. 
80a-2.(a), shall not be acquired or held, unless they are securities or 
other obligations of the Federal or a State government;
    (ii) The Trustee is authorized to invest the Fund in time or demand 
deposits of the Trustee, to the extent insured by an agency of the 
Federal or State government; and
    (iii) The Trustee is authorized to hold cash awaiting investment or 
distribution uninvested for a reasonable time and without liability for 
the payment of interest thereon.
    Section 7. Commingling and Investment. The Trustee is expressly 
authorized in its discretion:
    (a) To transfer from time to time any or all of the assets of the 
Fund to any common, commingled, or collective trust fund created by the 
Trustee in which the Fund is eligible to participate, subject to all of 
the provisions thereof, to be commingled with the assets of other trusts 
participating therein; and
    (b) To purchase shares in any investment company registered under 
the Investment Company Act of 1940, 15 U.S.C. 80a-1 et seq., including 
one which may be created, managed, underwritten, or to which investment 
advice is rendered or the shares of which are sold by the Trustee. The 
Trustee may vote such shares in its discretion.
    Section 8. Express Powers of Trustee. Without in any way limiting 
the powers and discretions conferred upon the Trustee by the other 
provisions of this Agreement or by law, the Trustee is expressly 
authorized and empowered:
    (a) To sell, exchange, convey, transfer, or otherwise dispose of any 
property held by it, by public or private sale. No person dealing with 
the Trustee shall be bound to see to the application of the purchase 
money or to inquire into the validity or expediency of any such sale or 
other disposition;
    (b) To make, execute, acknowledge, and deliver any and all documents 
of transfer and conveyance and any and all other instruments that may be 
necessary or appropriate to carry out the powers herein granted;
    (c) To register any securities held in the Fund in its own name or 
in the name of a nominee and to hold any security in bearer form or in 
book entry, or to combine certificates representing such securities with 
certificates of the same issue held by the Trustee in other fiduciary 
capacities, or to deposit or arrange for the deposit of such securities 
in a qualified central depositary even though, when so deposited, such 
securities may be merged and held in bulk in the name of the nominee of 
such depositary with other securities deposited therein by another 
person, or to deposit or arrange for the deposit of any securities 
issued by the United States Government, or any agency or instrumentality 
thereof, with a Federal Reserve bank, but the books and records of the 
Trustee shall at all times show that all such securities are part of the 
Fund;
    (d) To deposit any cash in the Fund in interest-bearing accounts 
maintained or savings certificates issued by the Trustee, in its

affiliated with the Trustee, to the extent insured by an agency of the 
Federal or State government; and

expenses incurred by the Trustee in connection with the administration 
of this Trust, including fees for legal services rendered to the

Trustee shall be paid from the Fund.
    Section 10. Annual Valuation. The Trustee shall annually, at least 
30 days prior to the anniversary date of establishment of the Fund, 
furnish to the Grantor and to the appropriate EPA Regional Administrator 
a statement confirming the value of the Trust. Any securities in the 
Fund shall be valued at market value as of no more than 60 days prior to 
the anniversary date of establishment of the Fund. The failure of the 
Grantor to object in writing to the Trustee within 90 days after the

reasonable compensation for its services as agreed upon in writing from 
time to time with the Grantor.

may replace the Trustee, but such resignation or replacement shall not 
be effective until the Grantor has appointed a successor trustee and 
this successor accepts the appointment. The successor trustee shall have 
the same powers and duties as those conferred upon the Trustee 
hereunder. Upon the successor trustee's acceptance of the appointment, 
the Trustee shall assign, transfer, and pay over to the successor 
trustee the funds and properties then constituting the Fund. If for any 
reason the Grantor cannot or does not act in the event of the 
resignation of the Trustee, the Trustee may apply to a court of 
competent jurisdiction for the appointment of a successor trustee or for 
instructions. The successor trustee shall specify the date on which it 
assumes administration of the trust in a writing sent to the Grantor, 
the EPA Regional Administrator, and the present Trustee by certified 
mail 10 days before such change becomes effective. Any expenses incurred 
by the Trustee as a result of any of the acts contemplated by this

instructions by the Grantor to the Trustee shall be in writing, signed 
by such persons as are designated in the attached Exhibit A or such 
other designees as the Grantor may designate by amendment to Exhibit A. 
The Trustee shall be fully protected in acting without inquiry in 
accordance with the Grantor's orders, requests, and instructions. All 
orders, requests, and instructions by the EPA Regional Administrator to 
the Trustee shall be in writing, signed by the EPA Regional 
Administrators of the Regions in which the facilities are located, or 
their designees, and the Trustee shall act and shall be fully protected 
in acting in accordance with such orders, requests, and instructions. 
The Trustee shall have the right to assume, in the absence of written 
notice to the contrary, that no event constituting a change or a 
termination of the authority of any person to act on behalf of the 
Grantor or EPA hereunder has occurred. The Trustee shall have no duty to 
act in the absence of such orders, requests, and instructions from the 
Grantor and/or EPA, except as provided for herein.
    Section 15. Notice of Nonpayment. The Trustee shall notify the 
Grantor and the appropriate EPA Regional Administrator, by certified 
mail within 10 days following the expiration of the 30-day period after 
the anniversary of the establishment of the Trust, if no payment is 
received from the Grantor during that period. After the pay-in period is 
completed, the Trustee shall not be required to send a notice of 
nonpayment.
    Section 16. Amendment of Agreement. This Agreement may be amended by 
an instrument in writing executed by the Grantor, the Trustee, and the 
appropriate EPA Regional Administrator, or by the Trustee and the 
appropriate EPA Regional Administrator if the Grantor ceases to exist.
    Section 17. Irrevocability and Termination. Subject to the right of 
the parties to amend this Agreement as provided in Section 16, this 
Trust shall be irrevocable and shall continue until terminated at the

Administrator, or by the Trustee and the EPA Regional Administrator, if

incur personal liability of any nature in connection with any act or 
omission, made in good faith, in the administration of this Trust, or in 
carrying out any directions by the Grantor or the EPA Regional 
Administrator issued in accordance with this Agreement. The Trustee 
shall be indemnified and saved harmless by the Grantor or from the Trust 
Fund, or both, from and against any personal liability to which the 
Trustee may be subjected by reason of any act or conduct in its official 
capacity, including all expenses reasonably incurred in its defense in 
the event the Grantor fails to provide such defense.
    Section 19. Choice of Law. This Agreement shall be administered, 
construed, and enforced according to the laws of the State of [insert 
name of State].

Date bond executed:
Effective date:
Principal: [legal name and business address of owner or operator]
Type of Organization: [insert ``individual,'' ``joint venture,''

State of incorporation:_________________________________________________
Surety(ies): [name(s) and business address(es)]

Surety's bond number:___________________________________________________

    Know All Persons By These Presents, That we, the Principal and 
Surety(ies) hereto are firmly bound to the U.S. Environmental Protection 
Agency (hereinafter called EPA), in the above penal sum for the payment 
of which we bind ourselves, our heirs, executors, administrators, 
successors, and assigns jointly and severally; provided that, where the 
Surety(ies) are corporations acting as co-sureties, we, the Sureties, 
bind ourselves in such sum ``jointly and severally'' only for the 
purpose of allowing a joint action or actions against any or all of us, 
and for all other purposes each Surety binds itself, jointly and 
severally with the Principal, for the payment of such sum only as is set 
forth opposite the name of such Surety, but if no limit of liability is 
indicated, the limit of liability shall be the full amount of the penal 
sum.
    Whereas said Principal is required, under the Resource Conservation 
and Recovery Act as amended (RCRA), to have a permit or interim status 
in order to own or operate each hazardous waste management facility 
identified above, and
    Whereas said Principal is required to provide financial assurance 
for closure, or closure and post-closure care, as a condition of the 
permit or interim status, and
    Whereas said Principal shall establish a standby trust fund as is 
required when a surety bond is used to provide such financial assurance;
    Now, Therefore, the conditions of the obligation are such that if 
the Principal shall faithfully, before the beginning of final closure of 
each facility identified above, fund the standby trust fund in the 
amount(s) identified above for the facility,
    Or, if the Principal shall fund the standby trust fund in such 
amount(s) within 15 days after a final order to begin closure is issued 
by an EPA Regional Administrator or a U.S. district court or other court 
of competent jurisdiction,
    Or, if the Principal shall provide alternate financial assurance, as 
specified in subpart H of 40 CFR part 264 or 265, as applicable, and 
obtain the EPA Regional Administrator's written approval of such 
assurance, within 90 days after the date notice of cancellation is 
received by both the Principal and the EPA Regional Administrator(s) 
from the Surety(ies), then this obligation shall be null and void; 
otherwise it is to remain in full force and effect.
    The Surety(ies) shall become liable on this bond obligation only 
when the Principal has failed to fulfill the conditions described above. 
Upon notification by an EPA Regional Administrator that the Principal 
has failed to perform as guaranteed by this bond, the Surety(ies) shall 
place funds in the amount guaranteed for the facility(ies) into the 
standby trust fund as directed by the EPA Regional Administrator.
    The liability of the Surety(ies) shall not be discharged by any 
payment or succession of payments hereunder, unless and until such 
payment or payments shall amount in the aggregate to the penal sum of 
the bond, but in no event shall the obligation of the Surety(ies) 
hereunder exceed the amount of said penal sum.
    The Surety(ies) may cancel the bond by sending notice of 
cancellation by certified mail to the Principal and to the EPA Regional 
Administrator(s) for the Region(s) in

[[Page 227]]

which the facility(ies) is (are) located, provided, however, that 
cancellation shall not occur during the 120 days beginning on the date 
of receipt of the notice of cancellation by both the Principal and the 
EPA Regional Administrator(s), as evidenced by the return receipts.
    The Principal may terminate this bond by sending written notice to 
the Surety(ies), provided, however, that no such notice shall become 
effective until the Surety(ies) receive(s) written authorization for 
termination of the bond by the EPA Regional Administrator(s) of the EPA 
Region(s) in which the bonded facility(ies) is (are) located.
    [The following paragraph is an optional rider that may be included 
but is not required.]
    Principal and Surety(ies) hereby agree to adjust the penal sum of 
the bond yearly so that it guarantees a new closure and/or post-closure 
amount, provided that the penal sum does not increase by more than 20 
percent in any one year, and no decrease in the penal sum takes place 
without the written permission of the EPA Regional Administrator(s).
    In Witness Whereof, the Principal and Surety(ies) have executed this 
Financial Guarantee Bond and have affixed their seals on the date set 
forth above.

    Know All Persons By These Presents, That we, the Principal and 
Surety(ies) hereto are firmly bound to the U.S. Environmental Protection 
Agency (hereinafter called EPA), in the above penal sum for the payment 
of which we bind ourselves, our heirs, executors, administrators, 
successors, and assigns jointly and severally; provided that, where the 
Surety(ies) are corporations acting as co-sureties, we, the Sureties, 
bind ourselves in such sum ``jointly and severally'' only for the 
purpose of allowing a joint action or actions against any or all of us, 
and for all other purposes each Surety binds itself, jointly and 
severally with the Principal, for the payment of such sum only as is set 
forth opposite the name of such Surety, but if no limit of liability is 
indicated, the limit of liability shall be the full amount of the penal 
sum.
    Whereas said Principal is required, under the Resource Conservation 
and Recovery Act as amended (RCRA), to have a permit in order to own or 
operate each hazardous waste management facility identified above, and
    Whereas said Principal is required to provide financial assurance 
for closure, or closure and post-closure care, as a condition of the 
permit, and
    Whereas said Principal shall establish a standby trust fund as is 
required when a surety bond is used to provide such financial assurance;
    Now, Therefore, the conditions of this obligation are such that if 
the Principal shall faithfully perform closure, whenever required to do 
so, of each facility for which this bond guarantees closure, in 
accordance with the closure plan and other requirements of the permit as 
such plan and permit may be amended, pursuant to all applicable laws, 
statutes, rules, and regulations, as such laws, statutes, rules, and 
regulations may be amended,
    And, if the Principal shall faithfully perform post-closure care of 
each facility for

[[Page 228]]

which this bond guarantees post-closure care, in accordance with the 
post-closure plan and other requirements of the permit, as such plan and 
permit may be amended, pursuant to all applicable laws, statutes, rules, 
and regulations, as such laws, statutes, rules, and regulations may be 
amended,
    Or, if the Principal shall provide alternate financial assurance as 
specified in subpart H of 40 CFR part 264, and obtain the EPA Regional 
Administrator's written approval of such assurance, within 90 days after 
the date notice of cancellation is received by both the Principal and 
the EPA Regional Administrator(s) from the Surety(ies), then this 
obligation shall be null and void, otherwise it is to remain in full 
force and effect.
    The Surety(ies) shall become liable on this bond obligation only 
when the Principal has failed to fulfill the conditions described above.
    Upon notification by an EPA Regional Administrator that the 
Principal has been found in violation of the closure requirements of 40 
CFR part 264, for a facility for which this bond guarantees performance 
of closure, the Surety(ies) shall either perform closure in accordance 
with the closure plan and other permit requirements or place the closure 
amount guaranteed for the facility into the standby trust fund as 
directed by the EPA Regional Administrator.
    Upon notification by an EPA Regional Administrator that the 
Principal has been found in violation of the post-closure requirements 
of 40 CFR part 264 for a facility for which this bond guarantees 
performance of post-closure care, the Surety(ies) shall either perform 
post-closure care in accordance with the post-closure plan and other 
permit requirements or place the post-closure amount guaranteed for the 
facility into the standby trust fund as directed by the EPA Regional 
Administrator.
    Upon notification by an EPA Regional Administrator that the 
Principal has failed to provide alternate financial assurance as 
specified in subpart H of 40 CFR part 264, and obtain written approval 
of such assurance from the EPA Regional Administrator(s) during the 90

Administrator(s) of a notice of cancellation of the bond, the 
Surety(ies) shall place funds in the amount guaranteed for the

    The surety(ies) hereby waive(s) notification of amendments to

regulations and agrees that no such amendment shall in any way alleviate 
its (their) obligation on this bond.
    The liability of the Surety(ies) shall not be discharged by any 
payment or succession of payments hereunder, unless and until such 
payment or payments shall amount in the aggregate to the penal sum of 
the bond, but in no event shall the obligation of the Surety(ies) 
hereunder exceed the amount of said penal sum.

    Section 3. Establishment of Fund. The Grantor and the Trustee hereby 
establish a trust fund, hereinafter the ``Fund,'' for the benefit of any 
and all third parties injured or damaged by [sudden and/or nonsudden] 
accidental occurrences arising from operation of the facility(ies)

Fund to any common commingled, or collective trust fund created by the 
Trustee in which the fund is eligible to participate, subject to all of 
the provisions thereof, to be commingled with the assets of other trusts 
participating therein; and
    (b) To purchase shares in any investment company registered under

in the name of a nominee and to hold any security in bearer form or in 
book entry, or to combine certificates representing such securities with

in a qualified central depositary even though, when so deposited, such 
securities may be merged and held in bulk in the name of the nominee of 
such depositary with other securities deposited therein by another 
person, or to deposit or arrange for the deposit of any securities 
issued by the United States Government, or any agency or instrumentality 
thereof, with a Federal Reserve bank, but the books and records of the 
Trustee shall at all times show that all such securities are part of the 
Fund;
    (d) To deposit any cash in the Fund in interest-bearing accounts 
maintained or savings certificates issued by the Trustee, in its

and to the appropriate EPA Regional Administrator a statement confirming 
the value of the Trust. Any securities in the Fund shall be valued at 
market value as of no more than 60 days prior to the anniversary date of 
establishment of the Fund. The failure of the Grantor to object in 
writing to the Trustee within 90 days after the statement has been 
furnished to the Grantor and the EPA Regional Administrator shall 
constitute a conclusively binding assent by the Grantor barring the 
Grantor from asserting any claim or liability against the Trustee with 
respect to matters disclosed in the statement.
    Section 11. Advice of Counsel. The Trustee may from time to time 
consult with counsel, who may be counsel to the Grantor with respect to 
any question arising as to the construction of this Agreement or any

    Section 12. Trustee Compensation. The Trustee shall be entitled to 
reasonable compensation for its services as agreed upon in writing from 
time to time with the Grantor.
    Section 13. Successor Trustee. The Trustee may resign or the Grantor 
may replace the Trustee, but such resignation or replacement shall not 
be effective until the Grantor has appointed a successor trustee and 
this successor accepts the appointment. The successor trustee shall have 
the same powers and duties as those conferred upon the Trustee 
hereunder. Upon the successor trustee's acceptance of the appointment, 
the Trustee shall assign, transfer, and pay over to the successor 
trustee the funds and properties then constituting the Fund. If for any 
reason the Grantor cannot or does not act in the event of the 
resignation of the Trustee, the Trustee may apply to a court of 
competent jurisdiction for the appointment of a successor trustee or for 
instructions. The successor trustee shall specify the date on which it 
assumes administration of the trust in a writing sent to the Grantor, 
the EPA Regional Administrator, and the present Trustee by certified 
mail 10 days before such change becomes effective. Any expenses incurred 
by the Trustee as a result of any of the acts contemplated by this 
section shall be paid as provided in Section 9.
    Section 14. Instructions to the Trustee. All orders, requests, and 
instructions by the Grantor to the Trustee shall be in writing, signed 
by such persons as are designated in the attached Exhibit A or such 
other designees as the Grantor may designate by amendments to Exhibit A. 
The Trustee shall be fully protected in acting without inquiry in 
accordance with the Grantor's orders, requests, and instructions. All 
orders, requests, and instructions by the EPA Regional Administrator to 
the Trustee shall be in writing, signed by the EPA Regional 
Administrators of the Regions in which the facilities are located, or 
their designees, and the Trustee shall act and shall be fully protected 
in acting in accordance with such orders, requests, and instructions. 
The Trustee shall have the right to assume, in the absence of written 
notice to the contrary, that no event constituting a change or a 
termination of the authority of any person to act on behalf of the 
Grantor or EPA hereunder has occurred. The Trustee shall have no duty to 
act in the absence of such orders, requests, and instructions from the 
Grantor and/or EPA, except as provided for herein.
    Section 15. Notice of Nonpayment. If a payment for bodily injury or 
property damage is made under Section 4 of this trust, the Trustee shall 
notify the Grantor of such payment and the amount(s) thereof within five 
(5) working days. The Grantor shall, on or before the anniversary date 
of the establishment of the Fund following such notice, either make 
payments to the Trustee in amounts sufficient to cause the trust to 
return to its value immediately prior to the payment of claims under 
Section 4, or shall provide written proof to the Trustee that other 
financial assurance for liability coverage has been obtained equalling 
the amount necessary to return the trust to its value prior to the 
payment of claims. If the Grantor does not either make payments to the 
Trustee or provide the Trustee with such proof, the Trustee shall within 
10 working days after the anniversary date of the establishment of the 
Fund provide a written notice of nonpayment to the EPA Regional 
Administrator.
    Section 16. Amendment of Agreement. This Agreement may be amended by 
an instrument in writing executed by the Grantor, the Trustee, and the 
appropriate EPA Regional Administrator, or by the Trustee and the 
appropriate EPA Regional Administrator if the Grantor ceases to exist.
    Section 17. Irrevocability and Termination. Subject to the right of 
the parties to amend this Agreement as provided in Section 16, this 
Trust shall be irrevocable and shall continue until terminated at the 
written agreement of the Grantor, the Trustee, and the EPA Regional 
Administrator, or by the Trustee and the EPA Regional Administrator, if 
the Grantor ceases to exist. Upon termination of the Trust, all 
remaining trust property, less final trust administration expenses, 
shall be delivered to the Grantor.
    The Regional Administrator will agree to termination of the Trust 
when the owner or operator substitutes alternate financial assurance as 
specified in this section.
    Section 18. Immunity and Indemnification. The Trustee shall not 
incur personal liability of any nature in connection with any act or 
omission, made in good faith, in the administration of this Trust, or in 
carrying out

[[Page 244]]

any directions by the Grantor or the EPA Regional Administrator issued 
in accordance with this Agreement. The Trustee shall be indemnified and 
saved harmless by the Grantor or from the Trust Fund, or both, from and 
against any personal liability to which the Trustee may be subjected by 
reason of any act or conduct in its official capacity, including all 
expenses reasonably incurred in its defense in the event the Grantor 
fails to provide such defense.
    Section 19. Choice of Law. This Agreement shall be administered, 
construed, and enforced according to the laws of the State of [enter

               Subpart I--Use and Management of Containers

    Source: 46 FR 2866, Jan. 12, 1981, unless otherwise noted.



Sec. 264.170  Applicability.

    The regulations in this subpart apply to owners and operators of all 
hazardous waste facilities that store containers of hazardous waste, 
except as Sec. 264.1 provides otherwise.

[Comment: Under Sec. 261.7 and Sec. 261.33(c), if a hazardous waste is 
emptied from a container the residue remaining in the container is not 
considered a hazardous waste if the container is ``empty'' as defined in 
Sec. 261.7. In that event, management of the container is exempt from 
the requirements of this subpart.]



Sec. 264.171  Condition of containers.

    If a container holding hazardous waste is not in good condition 
(e.g., severe rusting, apparent structural defects) or if it begins to 
leak, the owner or operator must transfer the hazardous waste from this 
container to a container that is in good condition or manage the waste 
in some other way that complies with the requirements of this part.



Sec. 264.172  Compatibility of waste with containers.

    The owner or operator must use a container made of or lined with 
materials which will not react with, and are otherwise compatible with, 
the hazardous waste to be stored, so that the ability of the container 
to contain the waste is not impaired.



Sec. 264.173  Management of containers.

    (a) A container holding hazardous waste must always be closed during 
storage, except when it is necessary to add or remove waste.
    (b) A container holding hazardous waste must not be opened, handled, 
or stored in a manner which may rupture the container or cause it to 
leak.

[Comment: Reuse of containers in transportation is governed by U.S. 
Department of Transportation regulations including those set forth in 49 
CFR 173.28.]



Sec. 264.174  Inspections.

    At least weekly, the owner or operator must inspect areas where 
containers are stored, looking for leaking containers and for 
deterioration of containers and the containment system caused by 
corrosion or other factors.

[Comment: See Secs. 264.15(c) and 264.171 for remedial action required 
if deterioration or leaks are detected.]



Sec. 264.175  Containment.

    (a) Container storage areas must have a containment system that is 
designed and operated in accordance with paragraph (b) of this section, 
except as otherwise provided by paragraph (c) of this section.
    (b) A containment system must be designed and operated as follows:
    (1) A base must underly the containers which is free of cracks or 
gaps and is sufficiently impervious to contain leaks, spills, and 
accumulated precipitation until the collected material is detected and 
removed;
    (2) The base must be sloped or the containment system must be 
otherwise designed and operated to drain and remove liquids resulting 
from leaks, spills, or precipitation, unless the containers are elevated 
or are otherwise protected from contact with accumulated liquids;
    (3) The containment system must have sufficient capacity to contain 
10% of the volume of containers or the volume of the largest container, 
whichever is greater. Containers that do not contain free liquids need 
not be considered in this determination;
    (4) Run-on into the containment system must be prevented unless the 
collection system has sufficient excess capacity in addition to that 
required in paragraph (b)(3) of this section to contain any run-on which 
might enter the system; and
    (5) Spilled or leaked waste and accumulated precipitation must be 
removed from the sump or collection area in as timely a manner as is 
necessary to prevent overflow of the collection system.

    [Comment: If the collected material is a hazardous waste under part 
261 of this Chapter, it must be managed as a hazardous waste in 
accordance with all applicable requirements of parts 262 through 266 of 
this chapter. If the collected material is discharged

[[Page 249]]

through a point source to waters of the United States, it is subject to 
the requirements of section 402 of the Clean Water Act, as amended.]

    (c) Storage areas that store containers holding only wastes that do 
not contain free liquids need not have a containment system defined by 
paragraph (b) of this section, except as provided by paragraph (d) of 
this section or provided that:
    (1) The storage area is sloped or is otherwise designed and operated 
to drain and remove liquid resulting from precipitation, or
    (2) The containers are elevated or are otherwise protected from 
contact with accumulated liquid.
    (d) Storage areas that store containers holding the wastes listed 
below that do not contain free liquids must have a containment system 
defined by paragraph (b) of this section:
    (1) FO20, FO21, FO22, FO23, FO26, and FO27.
    (2) [Reserved]

[46 FR 55112, Nov. 6, 1981, as amended at 50 FR 2003, Jan. 14, 1985]



Sec. 264.176  Special requirements for ignitable or reactive waste.

    Containers holding ignitable or reactive waste must be located at 
least 15 meters (50 feet) from the facility's property line.

[Comment: See Sec. 264.17(a) for additional requirements.]



Sec. 264.177  Special requirements for incompatible wastes.

    (a) Incompatible wastes, or incompatible wastes and materials (see 
appendix V for examples), must not be placed in the same container, 
unless Sec. 264.17(b) is complied with.
    (b) Hazardous waste must not be placed in an unwashed container that 
previously held an incompatible waste or material.

[Comment: As required by Sec. 264.13, the waste analysis plan must 
include analyses needed to comply with Sec. 264.177. Also, 
Sec. 264.17(c) requires wastes analyses, trial tests or other 
documentation to assure compliance with Sec. 264.17(b). As required by 
Sec. 264.73, the owner or operator must place the results of each waste 
analysis and trial test, and any documented information, in the 
operating record of the facility.]

    (c) A storage container holding a hazardous waste that is 
incompatible with any waste or other materials stored nearby in other 
containers, piles, open tanks, or surface impoundments must be separated 
from the other materials or protected from them by means of a dike, 
berm, wall, or other device.

[Comment: The purpose of this section is to prevent fires, explosions, 
gaseous emission, leaching, or other discharge of hazardous waste or 
hazardous waste constituents which could result from the mixing of 
incompatible wastes or materials if containers break or leak.]



Sec. 264.178  Closure.

    At closure, all hazardous waste and hazardous waste residues must be 
removed from the containment system. Remaining containers, liners, 
bases, and soil containing or contaminated with hazardous waste or 
hazardous waste residues must be decontaminated or removed.

[Comment: At closure, as throughout the operating period, unless the 
owner or operator can demonstrate in accordance with Sec. 261.3(d) of 
this chapter that the solid waste removed from the containment system is 
not a hazardous waste, the owner or operator becomes a generator of 
hazardous waste and must manage it in accordance with all applicable 
requirements of parts 262 through 266 of this chapter].



Sec. 264.179  Air emission standards.

    The owner or operator shall manage all hazardous waste placed in a 
container in accordance with the applicable requirements of subparts AA, 
BB, and CC of this part.

Sec. 264.191  Assessment of existing tank system's integrity.

    (a) For each existing tank system that does not have secondary 
containment meeting the requirements of Sec. 264.193, the owner or 
operator must determine that the tank system is not leaking or is unfit 
for use. Except as provided in paragraph (c) of this section, the owner 
or operator must obtain and keep on file at the facility a written 
assessment reviewed and certified by an independent, qualified 
registered professional engineer, in accordance with Sec. 270.11(d), 
that attests to the tank system's integrity by January 12, 1988.
    (b) This assessment must determine that the tank system is 
adequately designed and has sufficient structural strength and 
compatibility with the waste(s) to be stored or treated, to ensure that 
it will not collapse, rupture, or fail. At a minimum, this assessment 
must consider the following:
    (1) Design standard(s), if available, according to which the tank 
and ancillary equipment were constructed;
    (2) Hazardous characteristics of the waste(s) that have been and 
will be handled;
    (3) Existing corrosion protection measures;
    (4) Documented age of the tank system, if available (otherwise, an 
estimate of the age); and
    (5) Results of a leak test, internal inspection, or other tank 
integrity examination such that:
    (i) For non-enterable underground tanks, the assessment must include 
a leak test that is capable of taking into account the effects of 
temperature variations, tank end deflection, vapor pockets, and high 
water table effects, and
    (ii) For other than non-enterable underground tanks and for 
ancillary equipment, this assessment must include either a leak test, as 
described above, or other integrity examination, that is certified by an 
independent, qualified, registered professional engineer in accordance 
with Sec. 270.11(d), that addresses cracks, leaks, corrosion, and 
erosion.

    [Note: The practices described in the American Petroleum Institute 
(API) Publication, Guide for Inspection of Refinery Equipment, Chapter 
XIII, ``Atmospheric and Low-Pressure Storage Tanks,'' 4th edition, 1981, 
may be used, where applicable, as guidelines in conducting other than a 
leak test.]

    (c) Tank systems that store or treat materials that become hazardous 
wastes subsequent to July 14, 1986, must conduct this assessment within 
12 months after the date that the waste becomes a hazardous waste.
    (d) If, as a result of the assessment conducted in accordance with 
paragraph (a), a tank system is found to be leaking or unfit for use, 
the owner or operator must comply with the requirements of Sec. 264.196.

[51 FR 25472, July 14, 1986; 51 FR 29430, Aug. 15, 1986]



Sec. 264.192  Design and installation of new tank systems or components.

    (a) Owners or operators of new tank systems or components must 
obtain and submit to the Regional Administrator, at time of submittal of 
part B information, a written assessment, reviewed and certified by an 
independent,

[[Page 251]]

qualified registered professional engineer, in accordance with 
Sec. 270.11(d), attesting that the tank system has sufficient structural 
integrity and is acceptable for the storing and treating of hazardous 
waste. The assessment must show that the foundation, structural support, 
seams, connections, and pressure controls (if applicable) are adequately 
designed and that the tank system has sufficient structural strength, 
compatibility with the waste(s) to be stored or treated, and corrosion 
protection to ensure that it will not collapse, rupture, or fail. This 
assessment, which will be used by the Regional Administrator to review 
and approve or disapprove the acceptability of the tank system design, 
must include, at a minimum, the following information:
    (1) Design standard(s) according to which tank(s) and/or the 
ancillary equipment are constructed;
    (2) Hazardous characteristics of the waste(s) to be handled;
    (3) For new tank systems or components in which the external shell 
of a metal tank or any external metal component of the tank system will 
be in contact with the soil or with water, a determination by a 
corrosion expert of:
    (i) Factors affecting the potential for corrosion, including but not 
limited to:
    (A) Soil moisture content;
    (B) Soil pH;
    (C) Soil sulfides level;
    (D) Soil resistivity;
    (E) Structure to soil potential;
    (F) Influence of nearby underground metal structures (e.g., piping);
    (G) Existence of stray electric current;
    (H) Existing corrosion-protection measures (e.g., coating, cathodic 
protection), and
    (ii) The type and degree of external corrosion protection that are 
needed to ensure the integrity of the tank system during the use of the 
tank system or component, consisting of one or more of the following:
    (A) Corrosion-resistant materials of construction such as special 
alloys, fiberglass reinforced plastic, etc.;
    (B) Corrosion-resistant coating (such as epoxy, fiberglass, etc.) 
with cathodic protection (e.g., impressed current or sacrificial 
anodes); and
    (C) Electrical isolation devices such as insulating joints, flanges, 
etc.

    [Note: The practices described in the National Association of 
Corrosion Engineers (NACE) standard, ``Recommended Practice (RP-02-85)--
Control of External Corrosion on Metallic Buried, Partially Buried, or 
Submerged Liquid Storage Systems,'' and the American Petroleum Institute 
(API) Publication 1632, ``Cathodic Protection of Underground Petroleum 
Storage Tanks and Piping Systems,'' may be used, where applicable, as 
guidelines in providing corrosion protection for tank systems.]

    (4) For underground tank system components that are likely to be 
adversely affected by vehicular traffic, a determination of design or 
operational measures that will protect the tank system against potential 
damage; and
    (5) Design considerations to ensure that:
    (i) Tank foundations will maintain the load of a full tank;
    (ii) Tank systems will be anchored to prevent flotation or 
dislodgment where the tank system is placed in a saturated zone, or is 
located within a seismic fault zone subject to the standards of 
Sec. 264.18(a); and
    (iii) Tank systems will withstand the effects of frost heave.
    (b) The owner or operator of a new tank system must ensure that 
proper handling procedures are adhered to in order to prevent damage to 
the system during installation. Prior to covering, enclosing, or placing 
a new tank system or component in use, an independent, qualified 
installation inspector or an independent, qualified, registered 
professional engineer, either of whom is trained and experienced in the 
proper installation of tank systems or components, must inspect the 
system for the presence of any of the following items:
    (1) Weld breaks;
    (2) Punctures;
    (3) Scrapes of protective coatings;
    (4) Cracks;
    (5) Corrosion;
    (6) Other structural damage or inadequate construction/installation.

All discrepancies must be remedied before the tank system is covered, 
enclosed, or placed in use.
    (c) New tank systems or components that are placed underground and 
that

[[Page 252]]

are backfilled must be provided with a backfill material that is a 
noncorrosive, porous, homogeneous substance and that is installed so 
that the backfill is placed completely around the tank and compacted to 
ensure that the tank and piping are fully and uniformly supported.
    (d) All new tanks and ancillary equipment must be tested for 
tightness prior to being covered, enclosed, or placed in use. If a tank 
system is found not to be tight, all repairs necessary to remedy the 
leak(s) in the system must be performed prior to the tank system being 
covered, enclosed, or placed into use.
    (e) Ancillary equipment must be supported and protected against 
physical damage and excessive stress due to settlement, vibration, 
expansion, or contraction.

    [Note: The piping system installation procedures described in 
American Petroleum Institute (API) Publication 1615 (November 1979), 
``Installation of Underground Petroleum Storage Systems,'' or ANSI 
Standard B31.3, ``Petroleum Refinery Piping,'' and ANSI Standard B31.4 
``Liquid Petroleum Transportation Piping System,'' may be used, where 
applicable, as guidelines for proper installation of piping systems.]

    (f) The owner or operator must provide the type and degree of 
corrosion protection recommended by an independent corrosion expert, 
based on the information provided under paragraph (a)(3) of this 
section, or other corrosion protection if the Regional Administrator 
believes other corrosion protection is necessary to ensure the integrity 
of the tank system during use of the tank system. The installation of a 
corrosion protection system that is field fabricated must be supervised 
by an independent corrosion expert to ensure proper installation.
    (g) The owner or operator must obtain and keep on file at the 
facility written statements by those persons required to certify the 
design of the tank system and supervise the installation of the tank 
system in accordance with the requirements of paragraphs (b) through (f) 
of this section, that attest that the tank system was properly designed 
and installed and that repairs, pursuant to paragraphs (b) and (d) of 
this section, were performed. These written statements must also include 
the certification statement as required in Sec. 270.11(d) of this 
chapter.

reached 15 years of age, whichever comes later;
    (4) For those existing tank systems for which the age cannot be 
documented, within eight years of January 12, 1987; but if the age of 
the facility is greater than seven years, secondary containment must be 
provided by the time the facility reaches 15 years of age, or within two 
years of January 12, 1987, whichever comes later; and
    (5) For tank systems that store or treat materials that become 
hazardous wastes subsequent to January 12, 1987, within the time 
intervals required in paragraphs (a)(1) through (a)(4) of this section, 
except that the date that a material becomes a hazardous waste must be 
used in place of January 12, 1987.
    (b) Secondary containment systems must be:
    (1) Designed, installed, and operated to prevent any migration of 
wastes or accumulated liquid out of the system to the soil, ground 
water, or surface water at any time during the use of the tank system; 
and
    (2) Capable of detecting and collecting releases and accumulated 
liquids until the collected material is removed.

[[Page 253]]

    (c) To meet the requirements of paragraph (b) of this section, 
secondary containment systems must be at a minimum:
    (1) Constructed of or lined with materials that are compatible with 
the wastes(s) to be placed in the tank system and must have sufficient 
strength and thickness to prevent failure owing to pressure gradients 
(including static head and external hydrological forces), physical 
contact with the waste to which it is exposed, climatic conditions, and 
the stress of daily operation (including stresses from nearby vehicular 
traffic).
    (2) Placed on a foundation or base capable of providing support to 
the secondary containment system, resistance to pressure gradients above 
and below the system, and capable of preventing failure due to 
settlement, compression, or uplift;
    (3) Provided with a leak-detection system that is designed and 
operated so that it will detect the failure of either the primary or 
secondary containment structure or the presence of any release of 
hazardous waste or accumulated liquid in the secondary containment 
system within 24 hours, or at the earliest practicable time if the owner 
or operator can demonstrate to the Regional Administrator that existing 
detection technologies or site conditions will not allow detection of a 
release within 24 hours; and
    (4) Sloped or otherwise designed or operated to drain and remove 
liquids resulting from leaks, spills, or precipitation. Spilled or 
leaked waste and accumulated precipitation must be removed from the 
secondary containment system within 24 hours, or in as timely a manner 
as is possible to prevent harm to human health and the environment, if 
the owner or operator can demonstrate to the Regional Administrator that 
removal of the released waste or accumulated precipitation cannot be 
accomplished within 24 hours.

    [Note: If the collected material is a hazardous waste under part 261 
of this chapter, it is subject to management as a hazardous waste in 
accordance with all applicable requirements of parts 262 through 265 of 
this chapter. If the collected material is discharged through a point 
source to waters of the United States, it is subject to the requirements 
of sections 301, 304, and 402 of the Clean Water Act, as amended. If 
discharged to a Publicly Owned Treatment Works (POTW), it is sub]ect to 
the requirements of section 307 of the Clean Water Act, as amended. If 
the collected material is released to the environment, it may be subject 
to the reporting requirements of 40 CFR part 302.]

    (d) Secondary containment for tanks must include one or more of the 
following devices:

    (i) Designed or operated to contain 100 percent of the capacity of 
the largest tank within its boundary;
    (ii) Designed or operated to prevent run-on or infiltration of 
precipitation into the secondary containment system unless the 
collection system has sufficient excess capacity to contain run-on or 
infiltration. Such additional capacity must be sufficient to contain 
precipitation from a 25-year, 24-hour rainfall event.
    (iii) Free of cracks or gaps; and
    (iv) Designed and installed to surround the tank completely and to 
cover all surrounding earth likely to come into contact with the waste 
if the waste is released from the tank(s) (i.e., capable of preventing 
lateral as well as vertical migration of the waste).
    (2) Vault systems must be:
    (i) Designed or operated to contain 100 percent of the capacity of 
the largest tank within its boundary;
    (ii) Designed or operated to prevent run-on or infiltration of 
precipitation into the secondary containment system unless the 
collection system has sufficient excess capacity to contain run-on or 
infiltration. Such additional capacity must be sufficient to contain 
precipitation from a 25-year, 24-hour rainfall event:
    (iii) Constructed with chemical-resistant water stops in place at 
all joints (if any):

[[Page 254]]

    (iv) Provided with an impermeable interior coating or lining that is 
compatible with the stored waste and that will prevent migration of 
waste into the concrete;
    (v) Provided with a means to protect against the formation of and 
ignition of vapors within the vault, if the waste being stored or 
treated:
    (A) Meets the definition of ignitable waste under Sec. 262.21 of 
this chapter; or
    (B) Meets the definition of reactive waste under Sec. 262.21 of this 
chapter, and may form an ignitable or explosive vapor.
    (vi) Provided with an exterior moisture barrier or be otherwise 
designed or operated to prevent migration of moisture into the vault if 
the vault is subject to hydraulic pressure.
    (3) Double-walled tanks must be:
    (i) Designed as an integral structure (i.e., an inner tank 
completely enveloped within an outer shell) so that any release from the 
inner tank is contained by the outer shell.
    (ii) Protected, if constructed of metal, from both corrosion of the 
primary tank interior and of the external surface of the outer shell: 
and
    (iii) Provided with a built-in continuous leak detection system 
capable of detecting a release within 24 hours, or at the earliest 
practicable time, if the owner or operator can demonstrate to the 
Regional Administrator, and the Regional Administrator concludes, that 
the existing detection technology or site conditions would not allow 
detection of a release within 24 hours.

    [Note: The provisions outlined in the Steel Tank Institute's (STI) 
``Standard for Dual Wall Underground Steel Storage Tanks'' may be used 
as guidelines for aspects of the design of underground steel double-
walled tanks.]

    (f) Ancillary equipment must be provided with secondary containment 
(e.g., trench, jacketing, double-walled piping) that meets the 
requirements of paragraphs (b) and (c) of this section except for:
    (1) Aboveground piping (exclusive of flanges, joints, valves, and 
other connections) that are visually inspected for leaks on a daily 
basis;
    (2) Welded flanges, welded joints, and welded connections, that are 
visually inspected for leaks on a daily basis;
    (3) Sealless or magnetic coupling pumps and sealless valves, that 
are visually inspected for leaks on a daily basis; and
    (4) Pressurized aboveground piping systems with automatic shut-off 
devices (e.g., excess flow check valves, flow metering shutdown devices, 
loss of pressure actuated shut-off devices) that are visually inspected 
for leaks on a daily basis.
    (g) The owner or operator may obtain a variance from the 
requirements of this section if the Regional Administrator finds, as a 
result of a demonstration by the owner or operator that alternative 
design and operating practices, together with location characteristics, 
will prevent the migration of any hazardous waste or hazardous 
constituents into the ground water; or surface water at least as 
effectively as secondary containment during the active life of the tank 
system or that in the event of a release that does migrate to ground 
water or surface water, no substantial present or potential hazard will 
be posed to human health or the environment. New underground tank 
systems may not, per a demonstration in accordance with paragraph (g)(2) 
of this section, be exempted from the secondary containment requirements 
of this section.
    (1) In deciding whether to grant a variance based on a demonstration 
of equivalent protection of ground water and surface water, the Regional 
Administrator will consider:
    (i) The nature and quantity of the wastes;
    (ii) The proposed alternate design and operation;
    (iii) The hydrogeologic setting of the facility, including the 
thickness of soils present between the tank system and ground water, and
    (iv) All other factors that would influence the quality and mobility 
of the hazardous constituents and the potential for them to migrate to 
ground water or surface water
    (2) In deciding whether to grant a variance based on a demonstration 
of no substantial present or potential hazard, the Regional 
Administrator will consider:

[[Page 255]]

and land quality taking into account:
    (A) The physical and chemical characteristics of the waste in the 
tank system, including its potential for migration.
    (B) The hydrogeological characteristics of the facility and 
surrounding land,
    (C) The potential for health risks caused by human exposure to waste 
constituents,
    (D) The potential for damage to wildlife, crops, vegetation, and 
physical structures caused by exposure to waste constituents, and
    (E) The persistence and permanence of the potential adverse effects;
    (ii) The potential adverse effects of a release on ground-water 
quality, taking into account:
    (A) The quantity and quality of ground water and the direction of 
ground-water flow,
    (B) The proximity and withdrawal rates of ground-water users,
    (C) The current and future uses of ground water in the area, and
    (D) The existing quality of ground water, including other sources of 
contamination and their cumulative impact on the ground-water quality;
    (iii) The potential adverse effects of a release on surface water 
quality, taking into account:
    (A) The quantity and quality of ground water and the direction of 
ground-water flow,
    (B) The patterns of rainfall in the region,
    (C) The proximity of the tank system to surface waters,
    (D) The current and future uses of surface waters in the area and 
any water quality standards established for those surface waters, and
    (E) The existing quality of surface water, including other sources 
of contamination and the cumulative impact on surface-water quality; and
    (iv) The potential adverse effects of a release on the land 
surrounding the tank system, taking into account:
    (A) The patterns of rainfall in the region, and
    (B) The current and future uses of the surrounding land.
    (3) The owner or operator of a tank system, for which a variance 
from secondary containment had been granted in accordance with the 
requirements of paragraph (g)(1) of this section, at which a release of 
hazardous waste has occurred from the primary tank system but has not 
migrated beyond the zone of engineering control (as established in the 
variance), must:
    (i) Comply with the requirements of Sec. 264.196, except paragraph 
(d), and
    (ii) Decontaminate or remove contaminated soil to the extent 
necessary to:
    (A) Enable the tank system for which the variance was granted to 
resume operation with the capability for the detection of releases at 
least equivalent to the capability it had prior to the release; and
    (B) Prevent the migration of hazardous waste or hazardous 
constituents to ground water or surface water; and
    (iii) If contaminated soil cannot be removed or decontaminated in 
accordance with paragraph (g)(3)(ii) of this section, comply with the 
requirement of Sec. 264.197(b).
    (4) The owner or operator of a tank system, for which a variance 
from secondary containment had been granted in accordance with the 
requirements of paragraph (g)(1) of this section, at which a release of 
hazardous waste has occurred from the primary tank system and has 
migrated beyond the zone of engineering control (as established in the 
variance), must:
    (i) Comply with the requirements of Sec. 264.196 (a), (b), (c), and 
(d); and
    (ii) Prevent the migration of hazardous waste or hazardous 
constituents to ground water or surface water, if possible, and 
decontaminate or remove contaminated soil. If contaminated soil cannot 
be decontaminated or removed or if ground water has been contaminated, 
the owner or operator must comply with the requirements of 
Sec. 264.197(b); and
    (iii) If repairing, replacing, or reinstalling the tank system, 
provide secondary containment in accordance with the requirements of 
paragraphs (a) through (f) of this section or reapply for a variance 
from secondary containment and meet the requirements for new tank 
systems in Sec. 264.192

[[Page 256]]

if the tank system is replaced. The owner or operator must comply with 
these requirements even if contaminated soil can be decontaminated or 
removed and ground water or surface water has not been contaminated.
    (h) The following procedures must be followed in order to request a 
variance from secondary containment:
    (1) The Regional Administrator must be notified in writing by the 
owner or operator that he intends to conduct and submit a demonstration 
for a variance from secondary containment as allowed in paragraph (g) of 
this section according to the following schedule:
    (i) For existing tank systems, at least 24 months prior to the date 
that secondary containment must be provided in accordance with paragraph 
(a) of this section.
    (ii) For new tank systems, at least 30 days prior to entering into a 
contract for installation.
    (2) As part of the notification, the owner or operator must also 
submit to the Regional Administrator a description of the steps 
necessary to conduct the demonstration and a timetable for completing 
each of the steps. The demonstration must address each of the factors 
listed in paragraph (g)(1) or paragraph (g)(2) of this section;
    (3) The demonstration for a variance must be completed within 180 
days after notifying the Regional Administrator of an intent to conduct 
the demonstration; and
    (4) If a variance is granted under this paragraph, the Regional 
Administrator will require the permittee to construct and operate the 
tank system in the manner that was demonstrated to meet the requirements 
for the variance.
    (i) All tank systems, until such time as secondary containment that 
meets the requirements of this section is provided, must comply with the 
following:
    (1) For non-enterable underground tanks, a leak test that meets the 
requirements of Sec. 264.191(b)(5) or other tank integrity method, as 
approved or required by the Regional Administrator, must be conducted at 
least annually.
    (2) For other than non-enterable underground tanks, the owner or 
operator must either conduct a leak test as in paragraph (i)(1) of this 
section or develop a schedule and procedure for an assessment of the 
overall condition of the tank system by an independent, qualified 
registered professional engineer. The schedule and procedure must be 
adequate to detect obvious cracks, leaks, and corrosion or erosion that 
may lead to cracks and leaks. The owner or operator must remove the 
stored waste from the tank, if necessary, to allow the condition of all 
internal tank surfaces to be assessed. The frequency of these 
assessments must be based on the material of construction of the tank 
and its ancillary equipment, the age of the system, the type of 
corrosion or erosion protection used, the rate of corrosion or erosion 
observed during the previous inspection, and the characteristics of the 
waste being stored or treated.
    (3) For ancillary equipment, a leak test or other integrity 
assessment as approved by the Regional Administrator must be conducted 
at least annually.

    [Note: The practices described in the American Petroleum Institute 
(API) Publication Guide for Inspection of Refinery Equipment, Chapter 
XIII, ``Atmospheric and Low-Pressure Storage Tanks,'' 4th edition, 1981, 
may be used, where applicable, as guidelines for assessing the overall 
condition of the tank system.]

    (4) The owner or operator must maintain on file at the facility a 
record of the results of the assessments conducted in accordance with 
paragraphs (i)(1) through (i)(3) of this section.
    (5) If a tank system or component is found to be leaking or unfit 
for use as a result of the leak test or assessment in paragraphs (i)(1) 
through (i)(3) of this section, the owner or operator must comply with 
the requirements of Sec. 264.196.

Sec. 264.194   General operating requirements.

    (a) Hazardous wastes or treatment reagents must not be placed in a 
tank system if they could cause the tank, its ancillary equipment, or 
the containment system to rupture, leak, corrode, or otherwise fail.

[[Page 257]]

    (b) The owner or operator must use appropriate controls and 
practices to prevent spills and overflows from tank or containment 
systems. These include at a minimum:
    (1) Spill prevention controls (e.g., check valves, dry disconnect 
couplings);
    (2) Overfill prevention controls (e.g., level sensing devices, high 
level alarms, automatic feed cutoff, or bypass to a standby tank); and
    (3) Maintenance of sufficient freeboard in uncovered tanks to 
prevent overtopping by wave or wind action or by precipitation.
    (c) The owner or operator must comply with the requirements of 
Sec. 264.196 if a leak or spill occurs in the tank system.



Sec. 264.195  Inspections.

    (a) The owner or operator must develop and follow a schedule and 
procedure for inspecting overfill controls.
    (b) The owner or operator must inspect at least once each operating 
day:
    (1) Aboveground portions of the tank system, if any, to detect 
corrosion or releases of waste;
    (2) Data gathered from monitoring and leak detection equipment 
(e.g., pressure or temperature gauges, monitoring wells) to ensure that 
the tank system is being operated according to its design; and
    (3) The construction materials and the area immediately surrounding 
the externally accessible portion of the tank system, including the 
secondary containment system (e.g., dikes) to detect erosion or signs of 
releases of hazardous waste (e.g., wet spots, dead vegetation).

    [Note: Section 264.15(c) requires the owner or operator to remedy 
any deterioration or malfunction he finds. Section 264.196 requires the 
owner or operator to notify the Regional Administrator within 24 hours 
of confirming a leak. Also, 40 CFR part 302 may require the owner or 
operator to notify the National Response Center of a release.]

    (c) The owner or operator must inspect cathodic protection systems, 
if present, according to, at a minimum, the following schedule to ensure 
that they are functioning properly:
    (1) The proper operation of the cathodic protection system must be 
confirmed within six months after initial installation and annually 
thereafter; and
    (2) All sources of impressed current must be inspected and/or 
tested, as appropriate, at least bimonthly (i.e., every other month).

    [Note: The practices described in the National Association of 
Corrosion Engineers (NACE) standard, ``Recommended Practice (RP-02-85)--
Control of External Corrosion on Metallic Buried, Partially Buried, or 
Submerged Liquid Storage Systems,'' and the American Petroleum Institute 
(API) Publication 1632, ``Cathodic Protection of Underground Petroleum 
Storage Tanks and Piping Systems,'' may be used, where applicable, as 
guidelines in maintaining and inspecting cathodic protection systems.]

    (d) The owner or operator must document in the operating record of 
the facility an inspection of those items in paragraphs (a) through (c) 
of this section.



Sec. 264.196   Response to leaks or spills and disposition of leaking or unfit-for-use tank systems.

    A tank system or secondary containment system from which there has 
been a leak or spill, or which is unfit for use, must be removed from 
service immediately, and the owner or operator must satisfy the 
following requirements:
    (a) Cessation of use; prevent flow or addition of wastes. The owner 
or operator must immediately stop the flow of hazardous waste into the 
tank system or secondary containment system and inspect the system to 
determine the cause of the release.
    (b) Removal of waste from tank system or secondary containment 
system. (1) If the release was from the tank system, the owner/operator 
must, within 24 hours after detection of the leak or, if the owner/
operator demonstrates that it is not possible, at the earliest 
practicable time, remove as much of the waste as is necessary to prevent 
further release of hazardous waste to the environment and to allow 
inspection and repair of the tank system to be performed.
    (2) If the material released was to a secondary containment system, 
all released materials must be removed

[[Page 258]]

within 24 hours or in as timely a manner as is possible to prevent harm 
to human health and the environment.
    (c) Containment of visible releases to the environment. The owner/
operator must immediately conduct a visual inspection of the release 
and, based upon that inspection:
    (1) Prevent further migration of the leak or spill to soils or 
surface water; and
    (2) Remove, and properly dispose of, any visible contamination of 
the soil or surface water.
    (d) Notifications, reports. (1) Any release to the environment, 
except as provided in paragraph (d)(2) of this section, must be reported 
to the Regional Administrator within 24 hours of its detection. If the 
release has been reported pursuant to 40 CFR part 302, that report will 
satisfy this requirement.
    (2) A leak or spill of hazardous waste is exempted from the 
requirements of this paragraph if it is:
    (i) Less than or equal to a quantity of one (1) pound, and
    (ii) Immediately contained and cleaned up.
    (3) Within 30 days of detection of a release to the environment, a 
report containing the following information must be submitted to the 
Regional Administrator:
    (i) Likely route of migration of the release;
    (ii) Characteristics of the surrounding soil (soil composition, 
geology, hydrogeology, climate);
    (iii) Results of any monitoring or sampling conducted in connection 
with the release (if available). If sampling or monitoring data relating 
to the release are not available within 30 days, these data must be 
submitted to the Regional Administrator as soon as they become 
available.
    (iv) Proximity to downgradient drinking water, surface water, and 
populated areas; and
    (v) Description of response actions taken or planned.
    (e) Provision of secondary containment, repair, or closure. (1) 
Unless the owner/operator satisfies the requirements of paragraphs 
(e)(2) through (4) of this section, the tank system must be closed in 
accordance with Sec. 264.197.
    (2) If the cause of the release was a spill that has not damaged the 
integrity of the system, the owner/operator may return the system to 
service as soon as the released waste is removed and repairs, if 
necessary, are made.
    (3) If the cause of the release was a leak from the primary tank 
system into the secondary containment system, the system must be 
repaired prior to returning the tank system to service.
    (4) If the source of the release was a leak to the environment from 
a component of a tank system without secondary containment, the owner/
operator must provide the component of the system from which the leak 
occurred with secondary containment that satisfies the requirements of 
Sec. 264.193 before it can be returned to service, unless the source of 
the leak is an aboveground portion of a tank system that can be 
inspected visually. If the source is an aboveground component that can 
be inspected visually, the component must be repaired and may be 
returned to service without secondary containment as long as the 
requirements of paragraph (f) of this section are satisfied. If a 
component is replaced to comply with the requirements of this 
subparagraph, that component must satisfy the requirements for new tank 
systems or components in Secs. 264.192 and 264.193. Additionally, if a 
leak has occurred in any portion of a tank system component that is not 
readily accessible for visual inspection (e.g., the bottom of an 
inground or onground tank), the entire component must be provided with 
secondary containment in accordance with Sec. 264.193 prior to being 
returned to use.
    (f) Certification of major repairs. If the owner/operator has 
repaired a tank system in accordance with paragraph (e) of this section, 
and the repair has been extensive (e.g., installation of an internal 
liner; repair of a ruptured primary containment or secondary containment 
vessel), the tank system must not be returned to service unless the 
owner/operator has obtained a certification by an independent, 
qualified, registered, professional engineer in accordance with 
Sec. 270.11(d) that the repaired system is capable of handling hazardous 
wastes without release for

[[Page 259]]

the intended life of the system. This certification must be submitted to 
the Regional Administrator within seven days after returning the tank 
system to use.

    [Note: The Regional Administrator may, on the basis of any 
information received that there is or has been a release of hazardous 
waste or hazardous constituents into the environment, issue an order 
under RCRA section 3004(v), 3008(h), or 7003(a) requiring corrective 
action or such other response as deemed necessary to protect human 
health or the environment.]

    [Note: See Sec. 264.15(c) for the requirements necessary to remedy a 
failure. Also, 40 CFR part 302 may require the owner or operator to 
notify the National Response Center of certain releases.]

[51 FR 25472, July 14, 1986; 51 FR 29430, Aug. 15, 1986, as amended at 
53 FR 34086, Sept. 2, 1988]



Sec. 264.197   Closure and post-closure care.

    (a) At closure of a tank system, the owner or operator must remove 
or decontaminate all waste residues, contaminated containment system 
components (liners, etc.), contaminated soils, and structures and 
equipment contaminated with waste, and manage them as hazardous waste, 
unless Sec. 261.3(d) of this chapter applies. The closure plan, closure 
activities, cost estimates for closure, and financial responsibility for 
tank systems must meet all of the requirements specified in subparts G 
and H of this part.
    (b) If the owner or operator demonstrates that not all contaminated 
soils can be practicably removed or decontaminated as required in 
paragraph (a) of this section, then the owner or operator must close the 
tank system and perform post-closure care in accordance with the closure 
and post-closure care requirements that apply to landfills 
(Sec. 264.310). In addition, for the purposes of closure, post-closure, 
and financial responsibility, such a tank system is then considered to 
be a landfill, and the owner or operator must meet all of the 
requirements for landfills specified in subparts G and H of this part.
    (c) If an owner or operator has a tank system that does not have 
secondary containment that meets the requirements of Sec. 264.193 (b) 
through (f) and has not been granted a variance from the secondary 
containment requirements in accordance with Sec. 264.193(g), then:
    (1) The closure plan for the tank system must include both a plan 
for complying with paragraph (a) of this section and a contingent plan 
for complying with paragraph (b) of this section.
    (2) A contingent post-closure plan for complying with paragraph (b) 
of this section must be prepared and submitted as part of the permit 
application.
    (3) The cost estimates calculated for closure and post-closure care 
must reflect the costs of complying with the contingent closure plan and 
the contingent post-closure plan, if those costs are greater than the 
costs of complying with the closure plan prepared for the expected 
closure under paragraph (a) of this section.
    (4) Financial assurance must be based on the cost estimates in 
paragraph (c)(3) of this section.
    (5) For the purposes of the contingent closure and post-closure 
plans, such a tank system is considered to be a landfill, and the 
contingent plans must meet all of the closure, post-closure, and 
financial responsibility requirements for landfills under subparts G and 
H of this part.

Sec. 264.198   Special requirements for ignitable or reactive wastes.

    (a) Ignitable or reactive waste must not be placed in tank systems, 
unless:
    (1) The waste is treated, rendered, or mixed before or immediately 
after placement in the tank system so that:
    (i) The resulting waste, mixture, or dissolved material no longer 
meets the definition of ignitable or reactive waste under Secs. 261.21 
or 261.23 of this chapter, and
    (ii) Section 264.17(b) is complied with; or
    (2) The waste is stored or treated in such a way that it is 
protected from any material or conditions that may cause the waste to 
ignite or react; or
    (3) The tank system is used solely for emergencies.
    (b) The owner or operator of a facility where ignitable or reactive 
waste is

[[Page 260]]

stored or treated in a tank must comply with the requirements for the 
maintenance of protective distances between the waste management area 
and any public ways, streets, alleys, or an adjoining property line that 
can be built upon as required in Tables 2-1 through 2-6 of the National 
Fire Protection Association's ``Flammable and Combustible Liquids 
Code,'' (1977 or 1981), (incorporated by reference, see Sec. 260.11).



Sec. 264.199  Special requirements for incompatible wastes.

    (a) Incompatible wastes, or incompatible wastes and materials, must 
not be placed in the same tank system, unless Sec. 264.17(b) is complied 
with.
    (b) Hazardous waste must not be placed in a tank system that has not 
been decontaminated and that previously held an incompatible waste or 
material, unless Sec. 264.17(b) is complied with.



Sec. 264.200  Air emission standards.

    The owner or operator shall manage all hazardous waste placed in a 
tank in accordance with the applicable requirements of subparts AA, BB, 
and CC of this part.

[61 FR 59950, Nov. 25, 1996]



                     Subpart K--Surface Impoundments

    Source: 47 FR 32357, July 26, 1982, unless otherwise noted.



Sec. 264.220  Applicability.

    The regulations in this subpart apply to owners and operators of 
facilities that use surface impoundments to treat, store, or dispose of 
hazardous waste except as Sec. 264.1 provides otherwise.



Sec. 264.221  Design and operating requirements.

    (a) Any surface impoundment that is not covered by paragraph (c) of 
this section or Sec. 265.221 of this chapter must have a liner for all 
portions of the impoundment (except for existing portions of such 
impoundments). The liner must be designed, constructed, and installed to 
prevent any migration of wastes out of the impoundment to the adjacent 
subsurface soil or ground water or surface water at any time during the 
active life (including the closure period) of the impoundment. The liner 
may be constructed of materials that may allow wastes to migrate into 
the liner (but not into the adjacent subsurface soil or ground water or 
surface water) during the active life of the facility, provided that the 
impoundment is closed in accordance with Sec. 264.228(a)(1). For 
impoundments that will be closed in accordance with Sec. 264.228(a)(2), 
the liner must be constructed of materials that can prevent wastes from 
migrating into the liner during the active life of the facility. The 
liner must be:
    (1) Constructed of materials that have appropriate chemical 
properties and sufficient strength and thickness to prevent failure due 
to pressure gradients (including static head and external hydrogeologic 
forces), physical contact with the waste or leachate to which they are 
exposed, climatic conditions, the stress of installation, and the stress 
of daily operation;
    (2) Placed upon a foundation or base capable of providing support to 
the liner and resistance to pressure gradients above and below the liner 
to prevent failure of the liner due to settlement, compression, or 
uplift; and
    (3) Installed to cover all surrounding earth likely to be in contact 
with the waste or leachate.
    (b) The owner or operator will be exempted from the requirements of 
paragraph (a) of this section if the Regional Administrator finds, based 
on a demonstration by the owner or operator, that alternate design and 
operating practices, together with location characteristics, will 
prevent the migration of any hazardous constituents (see Sec. 264.93) 
into the ground water or surface water at any future time. In deciding 
whether to grant an exemption, the Regional Administrator will consider:
    (1) The nature and quantity of the wastes;
    (2) The proposed alternate design and operation;
    (3) The hydrogeologic setting of the facility, including the 
attenuative capacity and thickness of the liners and soils present 
between the impoundment and ground water or surface water; and

[[Page 261]]

    (4) All other factors which would influence the quality and mobility 
of the leachate produced and the potential for it to migrate to ground 
water or surface water.
    (c) The owner or operator of each new surface impoundment unit on 
which construction commences after January 29, 1992, each lateral 
expansion of a surface impoundment unit on which construction commences 
after July 29, 1992 and each replacement of an existing surface 
impoundment unit that is to commence reuse after July 29, 1992 must 
install two or more liners and a leachate collection and removal system 
between such liners. ``Construction commences'' is as defined in 
Sec. 260.10 of this chapter under ``existing facility''.
    (1)(i) The liner system must include:
    (A) A top liner designed and constructed of materials (e.g., a 
geomembrane) to prevent the migration of hazardous constituents into 
such liner during the active life and post-closure care period; and
    (B) A composite bottom liner, consisting of at least two components. 
The upper component must be designed and constructed of materials (e.g., 
a geomembrane) to prevent the migration of hazardous constituents into 
this component during the active life and post-closure care period. The 
lower component must be designed and constructed of materials to 
minimize the migration of hazardous constituents if a breach in the 
upper component were to occur. The lower component must be constructed 
of at least 3 feet (91 cm) of compacted soil material with a hydraulic 
conductivity of no more than 1 x 10/-7/ cm/sec.
    (ii) The liners must comply with paragraphs (a) (1), (2), and (3) of 
this section.
    (2) The leachate collection and removal system between the liners, 
and immediately above the bottom composite liner in the case of multiple 
leachate collection and removal systems, is also a leak detection 
system. This leak detection system must be capable of detecting, 
collecting, and removing leaks of hazardous constituents at the earliest 
practicable time through all areas of the top liner likely to be exposed 
to waste or leachate during the active life and post-closure care 
period. The requirements for a leak detection system in this paragraph 
are satisfied by installation of a system that is, at a minimum:
    (i) Constructed with a bottom slope of one percent or more;
    (ii) Constructed of granular drainage materials with a hydraulic 
conductivity of 1 x 10/-1/ cm/sec or more and a thickness of 
12 inches (30.5 cm) or more; or constructed of synthetic or geonet 
drainage materials with a transmissivity of 3 x 10/-4/ 
m\2\sec or more;
    (iii) Constructed of materials that are chemically resistant to the 
waste managed in the surface impoundment and the leachate expected to be 
generated, and of sufficient strength and thickness to prevent collapse 
under the pressures exerted by overlying wastes and any waste cover 
materials or equipment used at the surface impoundment;
    (iv) Designed and operated to minimize clogging during the active 
life and post-closure care period; and
    (v) Constructed with sumps and liquid removal methods (e.g., pumps) 
of sufficient size to collect and remove liquids from the sump and 
prevent liquids from backing up into the drainage layer. Each unit must 
have its own sump(s). The design of each sump and removal system must 
provide a method for measuring and recording the volume of liquids 
present in the sump and of liquids removed.
    (3) The owner or operator shall collect and remove pumpable liquids 
in the sumps to minimize the head on the bottom liner.
    (4) The owner or operator of a leak detection system that is not 
located completely above the seasonal high water table must demonstrate 
that the operation of the leak detection system will not be adversely 
affected by the presence of ground water.
    (d) The Regional Administrator may approve alternative design or 
operating practices to those specified in paragraph (c) of this section 
if the owner or operator demonstrates to the Regional Administrator that 
such design and operating practices, together with location 
characteristics:

[[Page 262]]

    (1) Will prevent the migration of any hazardous constituent into the 
ground water or surface water at least as effectively as the liners and 
leachate collection and removal system specified in paragraph (c) of 
this section; and
    (2) Will allow detection of leaks of hazardous constituents through 
the top liner at least as effectively.
    (e) The double liner requirement set forth in paragraph (c) of this 
section may be waived by the Regional Administrator for any monofill, 
if:
    (1) The monofill contains only hazardous wastes from foundry furnace 
emission controls or metal casting molding sand, and such wastes do not 
contain constituents which would render the wastes hazardous for reasons 
other than the EP toxicity characteristics in Sec. 261.24 of this 
chapter; and
    (2)(i)(A) The monofill has at least one liner for which there is no 
evidence that such liner is leaking. For the purposes of this paragraph, 
the term ``liner'' means a liner designed, constructed, installed, and 
operated to prevent hazardous waste from passing into the liner at any 
time during the active life of the facility, or a liner designed, 
constructed, installed, and operated to prevent hazardous waste from 
migrating beyond the liner to adjacent subsurface soil, ground water, or 
surface water at any time during the active life of the facility. In the 
case of any surface impoundment which has been exempted from the 
requirements of paragraph (c) of this section on the basis of a liner 
designed, constructed, installed, and operated to prevent hazardous 
waste from passing beyond the liner, at the closure of such impoundment, 
the owner or operator must remove or decontaminate all waste residues, 
all contaminated liner material, and contaminated soil to the extent 
practicable. If all contaminated soil is not removed or decontaminated, 
the owner or operator of such impoundment will comply with appropriate 
post-closure requirements, including but not limited to ground-water 
monitoring and corrective action;
    (B) The monofill is located more than one-quarter mile from an 
underground source of drinking water (as that term is defined in 
Sec. 144.3 of this chapter); and
    (C) The monofill is in compliance with generally applicable ground-
water monitoring requrements for facilities with permits under RCRA 
section 3005(c); or
    (ii) The owner or operator demonstrates that the monofill is 
located, designed and operated so as to assure that there will be no 
migration of any hazardous constituent into ground water or surface 
water at any future time.
    (f) The owner or operator of any replacement surface impoundment 
unit is exempt from paragraph (c) of this section if:
    (1) The existing unit was constructed in compliance with the design 
standards of sections 3004 (o)(1)(A)(i) and (o)(5) of the Resource 
Conservation and Recovery Act; and
    (2) There is no reason to believe that the liner is not functioning 
as designed.
    (g) A surface impoundment must be designed, constructed, maintained, 
and operated to prevent overtopping resulting from normal or abnormal 
operations; overfilling; wind and wave action; rainfall; run-on; 
malfunctions of level controllers, alarms, and other equipment; and 
human error.
    (h) A surface impoundment must have dikes that are designed, 
constructed, and maintained with sufficient structural integrity to 
prevent massive failure of the dikes. In ensuring structural integrity, 
it must not be presumed that the liner system will function without 
leakage during the active life of the unit.
    (i) The Regional Administrator will specify in the permit all design 
and operating practices that are necessary to ensure that the 
requirements of this section are satisfied.

Sec. 264.222  Action leakage rate.

    (a) The Regional Administrator shall approve an action leakage rate 
for surface impoundment units subject to Sec. 264.221 (c) or (d). The 
action leakage rate is the maximum design flow rate that the leak 
detection system (LDS) can remove without the fluid head on the bottom 
liner exceeding 1 foot. The

[[Page 263]]

action leakage rate must include an adequate safety margin to allow for 
uncertainties in the design (e.g., slope, hydraulic conductivity, 
thickness of drainage material), construction, operation, and location 
of the LDS, waste and leachate characteristics, likelihood and amounts 
of other sources of liquids in the LDS, and proposed response actions 
(e.g., the action leakage rate must consider decreases in the flow 
capacity of the system over time resulting from siltation and clogging, 
rib layover and creep of synthetic components of the system, overburden 
pressures, etc.).
    (b) To determine if the action leakage rate has been exceeded, the 
owner or operator must convert the weekly or monthly flow rate from the 
monitoring data obtained under Sec. 264.226(d) to an average daily flow 
rate (gallons per acre per day) for each sump. Unless the Regional 
Administrator approves a different calculation, the average daily flow 
rate for each sump must be calculated weekly during the active life and 
closure period, and if the unit is closed in accordance with 
Sec. 264.228(b), monthly during the post-closure care period when 
monthly monitoring is required under Sec. 264.226(d).

[57 FR 3487, Jan. 29, 1992]



Sec. 264.223  Response actions.

    (a) The owner or operator of surface impoundment units subject to 
Sec. 264.221 (c) or (d) must have an approved response action plan 
before receipt of waste. The response action plan must set forth the 
actions to be taken if the action leakage rate has been exceeded. At a 
minimum, the response action plan must describe the actions specified in 
paragraph (b) of this section.
    (b) If the flow rate into the leak detection system exceeds the 
action leakage rate for any sump, the owner or operator must:
    (1) Notify the Regional Administrator in writing of the exceedence 
within 7 days of the determination;
    (2) Submit a preliminary written assessment to the Regional 
Administrator within 14 days of the determination, as to the amount of 
liquids, likely sources of liquids, possible location, size, and cause 
of any leaks, and short-term actions taken and planned;
    (3) Determine to the extent practicable the location, size, and 
cause of any leak;
    (4) Determine whether waste receipt should cease or be curtailed, 
whether any waste should be removed from the unit for inspection, 
repairs, or controls, and whether or not the unit should be closed;
    (5) Determine any other short-term and longer-term actions to be 
taken to mitigate or stop any leaks; and
    (6) Within 30 days after the notification that the action leakage 
rate has been exceeded, submit to the Regional Administrator the results 
of the analyses specified in paragraphs (b) (3), (4), and (5) of this 
section, the results of actions taken, and actions planned. Monthly 
thereafter, as long as the flow rate in the leak detection system 
exceeds the action leakage rate, the owner or operator must submit to 
the Regional Administrator a report summarizing the results of any 
remedial actions taken and actions planned.
    (c) To make the leak and/or remediation determinations in paragraphs 
(b) (3), (4), and (5) of this section, the owner or operator must:
    (1)(i) Assess the source of liquids and amounts of liquids by 
source,
    (ii) Conduct a fingerprint, hazardous constituent, or other analyses 
of the liquids in the leak detection system to identify the source of 
liquids and possible location of any leaks, and the hazard and mobility 
of the liquid; and
    (iii) Assess the seriousness of any leaks in terms of potential for 
escaping into the environment; or
    (2) Document why such assessments are not needed.

Secs. 264.224--264.225  [Reserved]



Sec. 264.226  Monitoring and inspection.

    (a) During construction and installation, liners (except in the case 
of existing portions of surface impoundments exempt from 
Sec. 264.221(a)) and cover systems (e.g., membranes, sheets, or 
coatings) must be inspected for uniformity, damage, and imperfections 
(e.g., holes, cracks, thin spots, or foreign materials). Immediately 
after construction or installation:

[[Page 264]]

    (1) Synthetic liners and covers must be inspected to ensure tight 
seams and joints and the absence of tears, punctures, or blisters; and
    (2) Soil-based and admixed liners and covers must be inspected for 
inperfections including lenses, cracks, channels, root holes, or other 
structural non-uniformities that may cause an increase in the 
permeability of the liner or cover.
    (b) While a surface impoundment is in operation, it must be 
inspected weekly and after storms to detect evidence of any of the 
following:
    (1) Deterioration, malfunctions, or improper operation of 
overtopping control systems;
    (2) Sudden drops in the level of the impoundment's contents; and
    (3) Severe erosion or other signs of deterioration in dikes or other 
containment devices.
    (c) Prior to the issuance of a permit, and after any extended period 
of time (at least six months) during which the impoundment was not in 
service, the owner or operator must obtain a certification from a 
qualified engineer that the impoundment's dike, including that portion 
of any dike which provides freeboard, has structural integrity. The 
certification must establish, in particular, that the dike:
    (1) Will withstand the stress of the pressure exerted by the types 
and amounts of wastes to be placed in the impoundment; and
    (2) Will not fail due to scouring or piping, without dependence on 
any liner system included in the surface impoundment construction.
    (d)(1) An owner or operator required to have a leak detection system 
under Sec. 264.221 (c) or (d) must record the amount of liquids removed 
from each leak detection system sump at least once each week during the 
active life and closure period.
    (2) After the final cover is installed, the amount of liquids 
removed from each leak detection system sump must be recorded at least 
monthly. If the liquid level in the sump stays below the pump operating 
level for two consecutive months, the amount of liquids in the sumps 
must be recorded at least quarterly. If the liquid level in the sump 
stays below the pump operating level for two consecutive quarters, the 
amount of liquids in the sumps must be recorded at least semi-annually. 
If at any time during the post-closure care period the pump operating 
level is exceeded at units on quarterly or semi-annual recording 
schedules, the owner or operator must return to monthly recording of 
amounts of liquids removed from each sump until the liquid level again 
stays below the pump operating level for two consecutive months.
    (3) ``Pump operating level'' is a liquid level proposed by the owner 
or operator and approved by the Regional Administrator based on pump 
activation level, sump dimensions, and level that avoids backup into the 
drainage layer and minimizes head in the sump.

Sec. 264.227  Emergency repairs; contingency plans.

    (a) A surface impoundment must be removed from service in accordance 
with paragraph (b) of this section when:
    (1) The level of liquids in the impoundment suddenly drops and the 
drop is not known to be caused by changes in the flows into or out of 
the impoundment; or
    (2) The dike leaks.
    (b) When a surface impoundment must be removed from service as 
required by paragraph (a) of this section, the owner or operator must:
    (1) Immediately shut off the flow or stop the addition of wastes 
into the impoundment;
    (2) Immediately contain any surface leakage which has occurred or is 
occurring;
    (3) Immediately stop the leak;
    (4) Take any other necessary steps to stop or prevent catastrophic 
failure;
    (5) If a leak cannot be stopped by any other means, empty the 
impoundment; and
    (6) Notify the Regional Administrator of the problem in writing 
within seven days after detecting the problem.
    (c) As part of the contingency plan required in subpart D of this 
part, the owner or operator must specify a procedure for complying with 
the requirements of paragraph (b) of this section.

[[Page 265]]

    (d) No surface impoundment that has been removed from service in 
accordance with the requirements of this section may be restored to 
service unless the portion of the impoundment which was failing is 
repaired and the following steps are taken:
    (1) If the impoundment was removed from service as the result of 
actual or imminent dike failure, the dike's structural integrity must be 
recertified in accordance with Sec. 264.226(c).
    (2) If the impoundment was removed from service as the result of a 
sudden drop in the liquid level, then:
    (i) For any existing portion of the impoundment, a liner must be 
installed in compliance with Sec. 264.221(a); and
    (ii) For any other portion of the impoundment, the repaired liner 
system must be certified by a qualified engineer as meeting the design 
specifications approved in the permit.
    (e) A surface impoundment that has been removed from service in 
accordance with the requirements of this section and that is not being 
repaired must be closed in accordance with the provisions of 
Sec. 264.228.

Sec. 264.228  Closure and post-closure care.

    (a) At closure, the owner or operator must:
    (1) Remove or decontaminate all waste residues, contaminated 
containment system components (liners, etc.), contaminated subsoils, and 
structures and equipment contaminated with waste and leachate, and 
manage them as hazardous waste unless Sec. 261.3(d) of this chapter 
applies; or
    (2)(i) Eliminate free liquids by removing liquid wastes or 
solidifying the remaining wastes and waste residues;
    (ii) Stabilize remaining wastes to a bearing capacity sufficient to 
support final cover; and
    (iii) Cover the surface impoundment with a final cover designed and 
constructed to:
    (A) Provide long-term minimization of the migration of liquids 
through the closed impoundment;
    (B) Function with minimum maintenance;
    (C) Promote drainage and minimize erosion or abrasion of the final 
cover;
    (D) Accommodate settling and subsidence so that the cover's 
integrity is maintained; and
    (E) Have a permeability less than or equal to the permeability of 
any bottom liner system or natural subsoils present.
    (b) If some waste residues or contaminated materials are left in 
place at final closure, the owner or operator must comply with all post-
closure requirements contained in Secs. 264.117 through 264.120, 
including maintenance and monitoring throughout the post- closure care 
period (specified in the permit under Sec. 264.117). The owner or 
operator must:
    (1) Maintain the integrity and effectiveness of the final cover, 
including making repairs to the cap as necessary to correct the effects 
of settling, subsidence, erosion, or other events;
    (2) Maintain and monitor the leak detection system in accordance 
with Secs. 264.221(c)(2)(iv) and (3) and 264.226(d), and comply with all 
other applicable leak detection system requirements of this part;
    (3) Maintain and monitor the ground-water monitoring system and 
comply with all other applicable requirements of subpart F of this part; 
and
    (4) Prevent run-on and run-off from eroding or otherwise damaging 
the final cover.
    (c)(1) If an owner or operator plans to close a surface impoundment 
in accordance with paragraph (a)(1) of this section, and the impoundment 
does not comply with the liner requirements of Sec. 264.221(a) and is 
not exempt from them in accordance with Sec. 264.221(b), then:
    (i) The closure plan for the impoundment under Sec. 264.112 must 
include both a plan for complying with paragraph (a)(1) of this section 
and a contingent plan for complying with paragraph (a)(2) of this 
section in case not all contaminated subsoils can be practicably removed 
at closure; and
    (ii) The owner or operator must prepare a contingent post-closure 
plan under Sec. 264.118 for complying with paragraph (b) of this section 
in case not all contaminated subsoils can be practicably removed at 
closure.

Sec. 264.229  Special requirements for ignitable or reactive waste.

    Ignitable or reactive waste must not be placed in a surface 
impoundment, unless the waste and impoundment satisfy all applicable 
requirements of 40 CFR part 268, and:
    (a) The waste is treated, rendered, or mixed before or immediately 
after placement in the impoundment so that:
    (1) The resulting waste, mixture, or dissolution of material no 
longer meets the definition of ignitable or reactive waste under 
Sec. 261.21 or Sec. 261.23 of this chapter; and
    (2) Section 264.17(b) is complied with; or
    (b) The waste is managed in such a way that it is protected from any 
material or conditions which may cause it to ignite or react; or
    (c) The surface impoundment is used solely for emergencies.

Sec. 264.230  Special requirements for incompatible wastes.

    Incompatible wastes, or incompatible wastes and materials, (see 
appendix V of this part for examples) must not be placed in the same 
surface impoundment, unless Sec. 264.17(b) is complied with.



Sec. 264.231  Special requirements for hazardous wastes FO20, FO21, FO22, FO23, FO26, and FO27.

    (a) Hazardous Wastes FO20, FO21, FO22, FO23, FO26, and FO27 must not 
be placed in a surface impoundment unless the owner or operator operates 
the surface impoundment in accordance with a management plan for these 
wastes that is approved by the Regional Administrator pursuant to the 
standards set out in this paragraph, and in accord with all other 
applicable requirements of this part. The factors to be considered are:
    (1) The volume, physical, and chemical characteristics of the 
wastes, including their potential to migrate through soil or to 
volatilize or escape into the atmosphere;
    (2) The attenuative properties of underlying and surrounding soils 
or other materials;
    (3) The mobilizing properties of other materials co-disposed with 
these wastes; and
    (4) The effectiveness of additional treatment, design, or monitoring 
techniques.
    (b) The Regional Administrator may determine that additional design, 
operating, and monitoring requirements are necessary for surface 
impoundments managing hazardous wastes FO20, FO21, FO22, FO23, FO26, and 
FO27 in order to reduce the possibility of migration of these wastes to 
ground water, surface water, or air so as to protect human health and 
the environment.

                         Subpart L--Waste Piles

    Source: 47 FR 32359, July 26, 1982, unless otherwise noted.



Sec. 264.250  Applicability.

    (a) The regulations in this subpart apply to owners and operators of 
facilities that store or treat hazardous waste in piles, except as 
Sec. 264.1 provides otherwise.
    (b) The regulations in this subpart do not apply to owners or 
operators of waste piles that are closed with wastes left in place. Such 
waste piles are subject to regulation under subpart N of this part 
(Landfills).

[[Page 267]]

    (c) The owner or operator of any waste pile that is inside or under 
a structure that provides protection from precipitation so that neither 
run-off nor leachate is generated is not subject to regulation under 
Sec. 264.251 or under subpart F of this part, provided that:
    (1) Liquids or materials containing free liquids are not placed in 
the pile;
    (2) The pile is protected from surface water run-on by the structure 
or in some other manner;
    (3) The pile is designed and operated to control dispersal of the 
waste by wind, where necessary, by means other than wetting; and
    (4) The pile will not generate leachate through decomposition or 
other reactions.



Sec. 264.251  Design and operating requirements.

    (a) A waste pile (except for an existing portion of a waste pile) 
must have:
    (1) A liner that is designed, constructed, and installed to prevent 
any migration of wastes out of the pile into the adjacent subsurface 
soil or ground water or surface water at any time during the active life 
(including the closure period) of the waste pile. The liner may be 
constructed of materials that may allow waste to migrate into the liner 
itself (but not into the adjacent subsurface soil or ground water or 
surface water) during the active life of the facility. The liner must 
be:
    (i) Constructed of materials that have appropriate chemical 
properties and sufficient strength and thickness to prevent failure due 
to pressure gradients (including static head and external hydrogeologic 
forces), physical contact with the waste or leachate to which they are 
exposed, climatic conditions, the stress of installation, and the stress 
of daily operation;
    (ii) Placed upon a foundation or base capable of providing support 
to the liner and resistance to pressure gradients above and below the 
liner to prevent failure of the liner due to settlement, compression, or 
uplift; and
    (iii) Installed to cover all surrounding earth likely to be in 
contact with the waste or leachate; and
    (2) A leachate collection and removal system immediately above the 
liner that is designed, constructed, maintained, and operated to collect 
and remove leachate from the pile. The Regional Administrator will 
specify design and operating conditions in the permit to ensure that the 
leachate depth over the liner does not exceed 30 cm (one foot). The 
leachate collection and removal system must be:
    (i) Constructed of materials that are:
    (A) Chemically resistent to the waste managed in the pile and the 
leachate expected to be generated; and
    (B) Of sufficient strength and thickness to prevent collapse under 
the pressures exerted by overlaying wastes, waste cover materials, and 
by any equipment used at the pile; and
    (ii) Designed and operated to function without clogging through the 
scheduled closure of the waste pile.
    (b) The owner or operator will be exempted from the requirements of 
paragraph (a) of this section, if the Regional Administrator finds, 
based on a demonstration by the owner or operator, that alternate design 
and operating practices, together with location characteristics, will 
prevent the migration of any hazardous constituents (see Sec. 264.93) 
into the ground water or surface water at any future time. In deciding 
whether to grant an exemption, the Regional Administrator will consider:
    (1) The nature and quantity of the wastes;
    (2) The proposed alternate design and operation;
    (3) The hydrogeologic setting of the facility, including attenuative 
capacity and thickness of the liners and soils present between the pile 
and ground water or surface water; and
    (4) All other factors which would influence the quality and mobility 
of the leachate produced and the potential for it to migrate to ground 
water or surface water.
    (c) The owner or operator of each new waste pile unit on which 
construction commences after January 29, 1992, each lateral expansion of 
a waste pile unit on which construction commences after July 29, 1992, 
and each replacement of an existing waste pile unit that is to commence 
reuse after July 29, 1992 must install two or more liners and a leachate 
collection and removal system above and between such liners.

``Construction commences'' is as defined in Sec. 260.10 under ``existing 
facility''.
    (1)(i) The liner system must include:
    (A) A top liner designed and constructed of materials (e.g., a 
geomembrane) to prevent the migration of hazardous constituents into 
such liner during the active life and post-closure care period; and
    (B) A composite bottom liner, consisting of at least two components. 
The upper component must be designed and constructed of materials (e.g., 
a geomembrane) to prevent the migration of hazardous constituents into 
this component during the active life and post-closure care period. The 
lower component must be designed and constructed of materials to 
minimize the migration of hazardous constituents if a breach in the 
upper component were to occur. The lower component must be constructed 
of at least 3 feet (91 cm) of compacted soil material with a hydraulic 
conductivity of no more than 1 x 10-7 cm/sec.
    (ii) The liners must comply with paragraphs (a)(1)(i), (ii), and 
(iii) of this section.
    (2) The leachate collection and removal system immediately above the 
top liner must be designed, constructed, operated, and maintained to 
collect and remove leachate from the waste pile during the active life 
and post-closure care period. The Regional Administrator will specify 
design and operating conditions in the permit to ensure that the 
leachate depth over the liner does not exceed 30 cm (one foot). The 
leachate collection and removal system must comply with paragraphs 
(c)(3)(iii) and (iv) of this section.
    (3) The leachate collection and removal system between the liners, 
and immediately above the bottom composite liner in the case of multiple 
leachate collection and removal systems, is also a leak detection 
system. This leak detection system must be capable of detecting, 
collecting, and removing leaks of hazardous constituents at the earliest 
practicable time through all areas of the top liner likely to be exposed 
to waste or leachate during the active life and post-closure care 
period. The requirements for a leak detection system in this paragraph 
are satisfied by installation of a system that is, at a minimum:
    (i) Constructed with a bottom slope of one percent or more;
    (ii) Constructed of granular drainage materials with a hydraulic 
conductivity of 1 x 10-2 cm/sec or more and a thickness of 12 
inches (30.5 cm) or more; or constructed of synthetic or geonet drainage 
materials with a transmissivity of 3 x 10-5 m\2\/sec or more:
    (iii) Constructed of materials that are chemically resistant to the 
waste managed in the waste pile and the leachate expected to be 
generated, and of sufficient strength and thickness to prevent collapse 
under the pressures exerted by overlying wastes, waste cover materials, 
and equipment used at the waste pile;
    (iv) Designed and operated to minimize clogging during the active 
life and post-closure care period; and
    (v) Constructed with sumps and liquid removal methods (e.g., pumps) 
of sufficient size to collect and remove liquids from the sump and 
prevent liquids from backing up into the drainage layer. Each unit must 
have its own sump(s). The design of each sump and removal system must 
provide a method for measuring and recording the volume of liquids 
present in the sump and of liquids removed.
    (4) The owner or operator shall collect and remove pumpable liquids 
in the leak detection system sumps to minimize the head on the bottom 
liner.
    (5) The owner or operator of a leak detection system that is not 
located completely above the seasonal high water table must demonstrate 
that the operation of the leak detection system will not be adversely 
affected by the presence of ground water.
    (d) The Regional Administrator may approve alternative design or 
operating practices to those specified in paragraph (c) of this section 
if the owner or operator demonstrates to the Regional Administrator that 
such design and operating practices, together with location 
characteristics:
    (1) Will prevent the migration of any hazardous constituent into the 
ground

[[Page 269]]

water or surface water at least as effectively as the liners and 
leachate collection and removal systems specified in paragraph (c) of 
this section; and
    (2) Will allow detection of leaks of hazardous constituents through 
the top liner at least as effectively.
    (e) Paragraph (c) of this section does not apply to monofills that 
are granted a waiver by the Regional Administrator in accordance with 
Sec. 264.221(e).
    (f) The owner or operator of any replacement waste pile unit is 
exempt from paragraph (c) of this section if:
    (1) The existing unit was constructed in compliance with the design 
standards of section 3004(o)(1)(A)(i) and (o)(5) of the Resource 
Conservation and Recovery Act; and
    (2) There is no reason to believe that the liner is not functioning 
as designed.
    (g) The owner or operator must design, construct, operate, and 
maintain a run-on control system capable of preventing flow onto the 
active portion of the pile during peak discharge from at least a 25-year 
storm.
    (h) The owner or operator must design, construct, operate, and 
maintain a run-off management system to collect and control at least the 
water volume resulting from a 24-hour, 25-year storm.
    (i) Collection and holding facilities (e.g., tanks or basins) 
associated with run-on and run-off control systems must be emptied or 
otherwise managed expeditiously after storms to maintain design capacity 
of the system.
    (j) If the pile contains any particulate matter which may be subject 
to wind dispersal, the owner or operator must cover or otherwise manage 
the pile to control wind dispersal.
    (k) The Regional Administrator will specify in the permit all design 
and operating practices that are necessary to ensure that the 
requirements of this section are satisfied.

Sec. 264.252  Action leakage rate.

    (a) The Regional Administrator shall approve an action leakage rate 
for surface impoundment units subject to Sec. 264.251(c) or (d). The 
action leakage rate is the maximum design flow rate that the leak 
detection system (LDS) can remove without the fluid head on the bottom 
liner exceeding 1 foot. The action leakage rate must include an adequate 
safety margin to allow for uncertainties in the design (e.g., slope, 
hydraulic conductivity, thickness of drainage material), construction, 
operation, and location of the LDS, waste and leachate characteristics, 
likelihood and amounts of other sources of liquids in the LDS, and 
proposed response actions (e.g., the action leakage rate must consider 
decreases in the flow capacity of the system over time resulting from 
siltation and clogging, rib layover and creep of synthetic components of 
the system, overburden pressures, etc.).
    (b) To determine if the action leakage rate has been exceeded, the 
owner or operator must convert the weekly flow rate from the monitoring 
data obtained under Sec. 264.254(c), to an average daily flow rate 
(gallons per acre per day) for each sump. Unless the Regional 
Administrator approves a different calculation, the average daily flow 
rate for each sump must be calculated weekly during the active life and 
closure period.

[57 FR 3489, Jan. 29, 1992]



Sec. 264.253  Response actions.

    (a) The owner or operator of waste pile units subject to 
Sec. 264.251 (c) or (d) must have an approved response action plan 
before receipt of waste. The response action plan must set forth the 
actions to be taken if the action leakage rate has been exceeded. At a 
minimum, the response action plan must describe the actions specified in 
paragraph (b) of this section.
    (b) If the flow rate into the leak detection system exceeds the 
action leakage rate for any sump, the owner or operator must:
    (1) Notify the Regional Administrator in writing of the exceedance 
within 7 days of the determination;
    (2) Submit a preliminary written assessment to the Regional 
Administrator within 14 days of the determination, as to the amount of 
liquids, likely sources of liquids, possible location, size, and cause 
of any leaks, and short-term actions taken and planned;

[[Page 270]]

    (3) Determine to the extent practicable the location, size, and 
cause of any leak;
    (4) Determine whether waste receipt should cease or be curtailed, 
whether any waste should be removed from the unit for inspection, 
repairs, or controls, and whether or not the unit should be closed;
    (5) Determine any other short-term and long-term actions to be taken 
to mitigate or stop any leaks; and
    (6) Within 30 days after the notification that the action leakage 
rate has been exceeded, submit to the Regional Administrator the results 
of the analyses specified in paragraphs (b) (3), (4), and (5) of this 
section, the results of actions taken, and actions planned. Monthly 
thereafter, as long as the flow rate in the leak detection system 
exceeds the action leakage rate, the owner or operator must submit to 
the Regional Administrator a report summarizing the results of any 
remedial actions taken and actions planned.
    (c) To make the leak and/or remediation determinations in paragraphs 
(b) (3), (4), and (5) of this section, the owner or operator must:
    (1)(i) Assess the source of liquids and amounts of liquids by 
source,
    (ii) Conduct a fingerprint, hazardous constituent, or other analyses 
of the liquids in the leak detection system to identify the source of 
liquids and possible location of any leaks, and the hazard and mobility 
of the liquid; and
    (iii) Assess the seriousness of any leaks in terms of potential for 
escaping into the environment; or
    (2) Document why such assessments are not needed.

Sec. 264.254  Monitoring and inspection.

    (a) During construction or installation, liners (except in the case 
of existing portions of piles exempt from Sec. 264.251(a)) and cover 
systems (e.g., membranes, sheets, or coatings) must be inspected for 
uniformity, damage, and imperfections (e.g., holes, cracks, thin spots, 
or foreign materials). Immediately after construction or installation:
    (1) Synthetic liners and covers must be inspected to ensure tight 
seams and joints and the absence of tears, punctures, or blisters; and
    (2) Soil-based and admixed liners and covers must be inspected for 
imperfections including lenses, cracks, channels, root holes, or other 
structural non-uniformities that may cause an increase in the 
permeability of the liner or cover.
    (b) While a waste pile is in operation, it must be inspected weekly 
and after storms to detect evidence of any of the following:
    (1) Deterioration, malfunctions, or improper operation of run-on and 
run-off control systems;
    (2) Proper functioning of wind dispersal control systems, where 
present; and
    (3) The presence of leachate in and proper functioning of leachate 
collection and removal systems, where present.
    (c) An owner or operator required to have a leak detection system 
under Sec. 264.251(c) must record the amount of liquids removed from 
each leak detection system sump at least once each week during the 
active life and closure period.

Sec. 264.257  Special requirements for incompatible wastes.

    (a) Incompatible wastes, or incompatible wastes and materials, (see 
appendix V of this part for examples) must not be placed in the same 
pile, unless Sec. 264.17(b) is complied with.
    (b) A pile of hazardous waste that is incompatible with any waste or 
other material stored nearby in containers, other piles, open tanks, or 
surface impoundments must be separated from the other materials, or 
protected from them by means of a dike, berm, wall, or other device.
    (c) Hazardous waste must not be piled on the same base where 
incompatible wastes or materials were previously piled, unless the base 
has been decontaminated sufficiently to ensure compliance with 
Sec. 264.17(b).



Sec. 264.258  Closure and post-closure care.

    (a) At closure, the owner or operator must remove or decontaminate 
all waste residues, contaminated containment system components (liners, 
etc.), contaminated subsoils, and structures and equipment contaminated 
with waste and leachate, and manage them as hazardous waste unless 
Sec. 261.3(d) of this chapter applies.
    (b) If, after removing or decontaminating all residues and making 
all reasonable efforts to effect removal or decontamination of 
contaminated components, subsoils, structures, and equipment as required 
in paragraph (a) of this section, the owner or operator finds that not 
all contaminated subsoils can be practicably removed or decontaminated, 
he must close the facility and perform post-closure care in accordance 
with the closure and post-closure care requirements that apply to 
landfills (Sec. 264.310).
    (c)(1) The owner or operator of a waste pile that does not comply 
with the liner requirements of Sec. 264.251(a)(1) and is not exempt from 
them in accordance with Sec. 264.250(c) or Sec. 264.251(b), must:

    (a) Hazardous Wastes FO20, FO21, FO22, FO23, FO26, and FO27 must not 
be placed in waste piles that are not enclosed (as defined in 
Sec. 264.250(c)) unless the owner or operator operates the waste pile in 
accordance with a management plan for these wastes that is approved by 
the Regional Administrator pursuant to the standards set out in this 
paragraph, and in accord with all other applicable requirements of this 
part. The factors to be considered are:
    (1) The volume, physical, and chemical characteristics of the 
wastes, including their potential to migrate through soil or to 
volatilize or escape into the atmosphere;
    (2) The attenuative properties of underlying and surrounding soils

Sec. 264.270  Applicability.

    The regulations in this subpart apply to owners and operators of 
facilities that treat or dispose of hazardous waste in land treatment 
units, except as Sec. 264.1 provides otherwise.



Sec. 264.271  Treatment program.

    (a) An owner or operator subject to this subpart must establish a 
land treatment program that is designed to ensure that hazardous 
constituents placed in or on the treatment zone are degraded, 
transformed, or immobilized within the treatment zone. The Regional 
Administrator will specify in the facility permit the elements of the 
treatment program, including:
    (1) The wastes that are capable of being treated at the unit based 
on a demonstration under Sec. 264.272;
    (2) Design measures and operating practices necessary to maximize 
the success of degradation, transformation, and immobilization processes 
in the treatment zone in accordance with Sec. 264.273(a); and
    (3) Unsaturated zone monitoring provisions meeting the requirements 
of Sec. 264.278.
    (b) The Regional Administrator will specify in the facility permit 
the hazardous constituents that must be degraded, transformed, or 
immobilized under this subpart. Hazardous constituents are constituents 
identified in appendix VIII of part 261 of this chapter that are 
reasonably expected to be in, or derived from, waste placed in or on the 
treatment zone.
    (c) The Regional Administrator will specify the vertical and 
horizontal dimensions of the treatment zone in the facility permit. The 
treatment zone is the portion of the unsaturated zone below and 
including the land surface in which the owner or operator intends to 
maintain the conditions necessary for effective degradation, 
transformation, or immobilization of hazardous constituents. The maximum 
depth of the treatment zone must be:
    (1) No more than 1.5 meters (5 feet) from the initial soil surface; 
and
    (2) More than 1 meter (3 feet) above the seasonal high water table.

owner or operator must demonstrate, prior to application of the waste, 
that hazardous constituents in the waste can be completely degraded, 
transformed, or immobilized in the treatment zone.
    (b) In making this demonstration, the owner or operator may use 
field tests, laboratory analyses, available data, or, in the case of 
existing units, operating data. If the owner or operator intends to 
conduct field tests or laboratory analyses in order to make the 
demonstration required under paragraph (a) of this section, he must 
obtain a treatment or disposal permit under Sec. 270.63. The Regional 
Administrator will specify in this permit the testing, analytical, 
design, and operating requirements (including the duration of the tests 
and analyses, and, in the case of field tests, the horizontal and 
vertical dimensions of the treatment zone, monitoring procedures, 
closure and clean-up activities) necessary to meet the requirements in 
paragraph (c) of this section.
    (c) Any field test or laboratory analysis conducted in order to make 
a demonstration under paragraph (a) of this section must:
    (1) Accurately simulate the characteristics and operating conditions 
for the proposed land treatment unit including:
    (i) The characteristics of the waste (including the presence of 
appendix VIII of part 261 of this chapter constituents);
    (ii) The climate in the area;
    (iii) The topography of the surrounding area;
    (iv) The characteristics of the soil in the treatment zone 
(including depth); and
    (v) The operating practices to be used at the unit.
    (2) Be likely to show that hazardous constituents in the waste to be 
tested

[[Page 273]]

will be completely degraded, transformed, or immobilized in the 
treatment zone of the proposed land treatment unit; and
    (3) Be conducted in a manner that protects human health and the 
environment considering:
    (i) The characteristics of the waste to be tested;
    (ii) The operating and monitoring measures taken during the course 
of the test;
    (iii) The duration of the test;
    (iv) The volume of waste used in the test;
    (v) In the case of field tests, the potential for migration of 
hazardous constituents to ground water or surface water.

constituents during the active life of the land treatment unit.
    (c) The owner or operator must design, construct, operate, and 
maintain a run-on control system capable of preventing flow onto the 
treatment zone during peak discharge from at least a 25-year storm.
    (d) The owner or operator must design, construct, operate, and 
maintain a run-off management system to collect and control at least the 
water volume resulting from a 24-hour, 25-year storm.
    (e) Collection and holding facilities (e.g., tanks or basins) 
associated with run-on and run-off control systems must be emptied or 
otherwise managed expeditiously after storms to maintain the design 
capacity of the system.
    (f) If the treatment zone contains particulate matter which may be 
subject to wind dispersal, the owner or operator must manage the unit to 
control wind dispersal.
    (g) The owner or operator must inspect the unit weekly and after 
storms to detect evidence of:
    (1) Deterioration, malfunctions, or improper operation of run-on and 
run-off control systems; and
    (2) Improper functioning of wind dispersal control measures.

whichever occurs later, and this pH level must be maintained whenever 
food-chain crops are grown;
    (iii) There must be an operating plan which demonstrates how the 
animal feed will be distributed to preclude ingestion by humans. The 
operating plan must describe the measures to be taken to safeguard 
against possible health hazards from cadmium entering the food chain, 
which may result from alternative land uses; and
    (iv) Future property owners must be notified by a stipulation in the 
land record or property deed which states that the property has received 
waste at high cadmium application rates and that food-chain crops must 
not be grown except in compliance with paragraph (b)(2) of this section.
Sec. 264.277  [Reserved]



Sec. 264.278  Unsaturated zone monitoring.

    An owner or operator subject to this subpart must establish an 
unsaturated zone monitoring program to discharge the following 
responsibilities:

[[Page 275]]

    (a) The owner or operator must monitor the soil and soil-pore liquid 
to determine whether hazardous constituents migrate out of the treatment 
zone.
    (1) The Regional Administrator will specify the hazardous 
constituents to be monitored in the facility permit. The hazardous 
constituents to be monitored are those specified under Sec. 264.271(b).
    (2) The Regional Administrator may require monitoring for principal 
hazardous constituents (PHCs) in lieu of the constituents specified 
under Sec. 264.271(b). PHCs are hazardous constituents contained in the 
wastes to be applied at the unit that are the most difficult to treat, 
considering the combined effects of degradation, transformation, and 
immobilization. The Regional Administrator will establish PHCs if he 
finds, based on waste analyses, treatment demonstrations, or other data, 
that effective degradation, transformation, or immobilization of the 
PHCs will assure treatment at at least equivalent levels for the other 
hazardous constituents in the wastes.
    (b) The owner or operator must install an unsaturated zone 
monitoring system that includes soil monitoring using soil cores and 
soil-pore liquid monitoring using devices such as lysimeters. The 
unsaturated zone monitoring system must consist of a sufficient number 
of sampling points at appropriate locations and depths to yield samples 
that:
    (1) Represent the quality of background soil-pore liquid quality and 
the chemical make-up of soil that has not been affected by leakage from 
the treatment zone; and
    (2) Indicate the quality of soil-pore liquid and the chemical make-
up of the soil below the treatment zone.
    (c) The owner or operator must establish a background value for each 
hazardous constituent to be monitored under paragraph (a) of this 
section. The permit will specify the background values for each 
constituent or specify the procedures to be used to calculate the 
background values.
    (1) Background soil values may be based on a one-time sampling at a 
background plot having characteristics similar to those of the treatment 
zone.
    (2) Background soil-pore liquid values must be based on at least 
quarterly sampling for one year at a background plot having 
characteristics similar to those of the treatment zone.
    (3) The owner or operator must express all background values in a 
form necessary for the determination of statistically significant 
increases under paragraph (f) of this section.
    (4) In taking samples used in the determination of all background 
values, the owner or operator must use an unsaturated zone monitoring 
system that complies with paragraph (b)(1) of this section.
    (d) The owner or operator must conduct soil monitoring and soil-pore 
liquid monitoring immediately below the treatment zone. The Regional 
Administrator will specify the frequency and timing of soil and soil-
pore liquid monitoring in the facility permit after considering the 
frequency, timing, and rate of waste application, and the soil 
permeability. The owner or operator must express the results of soil and 
soil-pore liquid monitoring in a form necessary for the determination of 
statistically significant increases under paragraph (f) of this section.
    (e) The owner or operator must use consistent sampling and analysis 
procedures that are designed to ensure sampling results that provide a 
reliable indication of soil-pore liquid quality and the chemical make-up 
of the soil below the treatment zone. At a minimum, the owner or 
operator must implement procedures and techniques for:
    (1) Sample collection;
    (2) Sample preservation and shipment;
    (3) Analytical procedures; and
    (4) Chain of custody control.
    (f) The owner or operator must determine whether there is a 
statistically significant change over background values for any 
hazardous constituent to be monitored under paragraph (a) of this 
section below the treatment zone each time he conducts soil monitoring 
and soil-pore liquid monitoring under paragraph (d) of this section.
    (1) In determining whether a statistically significant increase has 
occurred, the owner or operator must compare the value of each 
constituent, as determined under paragraph (d) of

[[Page 276]]

this section, to the background value for that constituent according to 
the statistical procedure specified in the facility permit under this 
paragraph.
    (2) The owner or operator must determine whether there has been a 
statistically significant increase below the treatment zone within a 
reasonable time period after completion of sampling. The Regional 
Administrator will specify that time period in the facility permit after 
considering the complexity of the statistical test and the availability 
of laboratory facilities to perform the analysis of soil and soil-pore 
liquid samples.
    (3) The owner or operator must determine whether there is a 
statistically significant increase below the treatment zone using a 
statistical procedure that provides reasonable confidence that migration 
from the treatment zone will be identified. The Regional Administrator 
will specify a statistical procedure in the facility permit that he 
finds:
    (i) Is appropriate for the distribution of the data used to 
establish background values; and
    (ii) Provides a reasonable balance between the probability of 
falsely identifying migration from the treatment zone and the 
probability of failing to identify real migration from the treatment 
zone.
    (g) If the owner or operator determines, pursuant to paragraph (f) 
of this section, that there is a statistically significant increase of 
hazardous constituents below the treatment zone, he must:
    (1) Notify the Regional Administrator of this finding in writing 
within seven days. The notification must indicate what constituents have 
shown statistically significant increases.
    (2) Within 90 days, submit to the Regional Administrator an 
application for a permit modification to modify the operating practices 
at the facility in order to maximize the success of degradation, 
transformation, or immobilization processes in the treatment zone.
    (h) If the owner or operator determines, pursuant to paragraph (f) 
of this section, that there is a statistically significant increase of 
hazardous constituents below the treatment zone, he may demonstrate that 
a source other than regulated units caused the increase or that the 
increase resulted from an error in sampling, analysis, or evaluation. 
While the owner or operator may make a demonstration under this 
paragraph in addition to, or in lieu of, submitting a permit 
modification application under paragraph (g)(2) of this section, he is 
not relieved of the requirement to submit a permit modification 
application within the time specified in paragraph (g)(2) of this 
section unless the demonstration made under this paragraph successfully 
shows that a source other than regulated units caused the increase or 
that the increase resulted from an error in sampling, analysis, or 
evaluation. In making a demonstration under this paragraph, the owner or 
operator must:
    (1) Notify the Regional Administrator in writing within seven days 
of determining a statistically significant increase below the treatment 
zone that he intends to make a determination under this paragraph;
    (2) Within 90 days, submit a report to the Regional Administrator 
demonstrating that a source other than the regulated units caused the 
increase or that the increase resulted from error in sampling, analysis, 
or evaluation;
    (3) Within 90 days, submit to the Regional Administrator an 
application for a permit modification to make any appropriate changes to 
the unsaturated zone monitoring program at the facility; and
    (4) Continue to monitor in accordance with the unsaturated zone 
monitoring program established under this section.

Sec. 264.280  Closure and post-closure care.

    (a) During the closure period the owner or operator must:

[[Page 277]]

    (1) Continue all operations (including pH control) necessary to 
maximize degradation, transformation, or immobilization of hazardous 
constituents within the treatment zone as required under 
Sec. 264.273(a), except to the extent such measures are inconsistent 
with paragraph (a)(8) of this section.
    (2) Continue all operations in the treatment zone to minimize run-
off of hazardous constituents as required under Sec. 264.273(b);
    (3) Maintain the run-on control system required under 
Sec. 264.273(c);
    (4) Maintain the run-off management system required under 
Sec. 264.273(d);
    (5) Control wind dispersal of hazardous waste if required under 
Sec. 264.273(f);
    (6) Continue to comply with any prohibitions or conditions 
concerning growth of food-chain crops under Sec. 264.276;
    (7) Continue unsaturated zone monitoring in compliance with 
Sec. 264.278, except that soil-pore liquid monitoring may be terminated 
90 days after the last application of waste to the treatment zone; and
    (8) Establish a vegetative cover on the portion of the facility 
being closed at such time that the cover will not substantially impede 
degradation, transformation, or immobilization of hazardous constituents 
in the treatment zone. The vegetative cover must be capable of 
maintaining growth without extensive maintenance.
    (b) For the purpose of complying with Sec. 264.115, when closure is 
completed the owner or operator may submit to the Regional Administrator 
certification by an independent qualified soil scientist, in lieu of an 
independent registered professional engineer, that the facility has been 
closed in accordance with the specifications in the approved closure 
plan.
    (c) During the post-closure care period the owner or operator must:
    (1) Continue all operations (including pH control) necessary to 
enhance degradation and transformation and sustain immobilization of 
hazardous constituents in the treatment zone to the extent that such 
measures are consistent with other post-closure care activities;
    (2) Maintain a vegetative cover over closed portions of the 
facility;
    (3) Maintain the run-on control system required under 
Sec. 264.273(c);
    (4) Maintain the run-off management system required under 
Sec. 264.273(d);
    (5) Control wind dispersal of hazardous waste if required under 
Sec. 264.273(f);
    (6) Continue to comply with any prohibitions or conditions 
concerning growth of food-chain crops under Sec. 264.276; and
    (7) Continue unsaturated zone monitoring in compliance with 
Sec. 264.278, expect that soil-pore liquid monitoring may be terminated 
90 days after the last application of waste to the treatment zone.
    (d) The owner or operator is not subject to regulation under 
paragraphs (a)(8) and (c) of this section if the Regional Administrator 
finds that the level of hazardous constituents in the treatment zone 
soil does not exceed the background value of those constituents by an 
amount that is statistically significant when using the test specified 
in paragraph (d)(3) of this section. The owner or operator may submit 
such a demonstration to the Regional Administrator at any time during 
the closure of post-closure care periods. For the purposes of this 
paragraph:
    (1) The owner or operator must establish background soil values and 
determine whether there is a statistically significant increase over 
those values for all hazardous constituents specified in the facility 
permit under Sec. 264.271 (b).
    (i) Background soil values may be based on a one-time sampling of a 
background plot having characteristics similar to those of the treatment 
zone.
    (ii) The owner or operator must express background values and values 
for hazardous constituents in the treatment zone in a form necessary for 
the determination of statistically significant increases under paragraph 
(d)(3) of this section.
    (2) In taking samples used in the determination of background and 
treatment zone values, the owner or operator must take samples at a 
sufficient number of sampling points and at appropriate locations and 
depths to yield samples that represent the chemical make-up of soil that 
has not been affected by leakage from the treatment zone and the soil 
within the treatment zone, respectively.

[[Page 278]]

    (3) In determining whether a statistically significant increase has 
occurred, the owner or operator must compare the value of each 
constituent in the treatment zone to the background value for that 
constituent using a statistical procedure that provides reasonable 
confidence that constituent presence in the treatment zone will be 
identified. The owner or operator must use a statistical procedure that:
    (i) Is appropriate for the distribution of the data used to 
establish background values; and
    (ii) Provides a reasonable balance between the probability of 
falsely identifying hazardous constituent presence in the treatment zone 
and the probability of failing to identify real presence in the 
treatment zone.
    (e) The owner or operator is not subject to regulation under Subpart 
F of this chapter if the Regional Administrator finds that the owner or 
operator satisfies paragraph (d) of this section and if unsaturated zone 
monitoring under Sec. 264.278 indicates that hazardous constituents have 
not migrated beyond the treatment zone during the active life of the 
land treatment unit.



Sec. 264.281  Special requirements for ignitable or reactive waste.

    The owner or operator must not apply ignitable or reactive waste to 
the treatment zone unless the waste and the treatment zone meet all 
applicable requirements of 40 CFR part 268, and:
    (a) The waste is immediately incorporated into the soil so that:
    (1) The resulting waste, mixture, or dissolution of material no 
longer meets the definition of ignitable or reactive waste under 
Sec. 261.21 or Sec. 261.23 of this chapter; and
    (2) Section 264.17(b) is complied with; or
    (b) The waste is managed in such a way that it is protected from any 
material or conditions which may cause it to ignite or react.

[47 FR 32361, July 26, 1982, as amended at 55 FR 22685, June 1, 1990]



Sec. 264.282  Special requirements for incompatible wastes.

    The owner or operator must not place incompatible wastes, or 
incompatible wastes and materials (see appendix V of this part for 
examples), in or on the same treatment zone, unless Sec. 264.17(b) is 
complied with.



Sec. 264.283  Special requirements for hazardous wastes FO20, FO21, FO22, FO23, FO26, and FO27.

    (a) Hazardous Wastes FO20, FO21, FO22, FO23, FO26 and, FO27 must not 
be placed in a land treatment unit unless the owner or operator operates 
the facility in accordance with a management plan for these wastes that 
is approved by the Regional Administrator pursuant to the standards set 
out in this paragraph, and in accord with all other applicable 
requirements of this part. The factors to be considered are:
    (1) The volume, physical, and chemical characteristics of the 
wastes, including their potential to migrate through soil or to 
volatilize or escape into the atmosphere;
    (2) The attenuative properties of underlying and surrounding soils 
or other materials;
    (3) The mobilizing properties of other materials co-disposed with 
these wastes; and
    (4) The effectiveness of additional treatment, design, or monitoring 
techniques.
    (b) The Regional Administrator may determine that additional design, 
operating, and monitoring requirements are necessary for land treatment 
facilities managing hazardous wastes FO20, FO21, FO22, FO23, FO26, and 
FO27 in order to reduce the possibility of migration of these wastes to 
ground water, surface water, or air so as to protect human health and 
the environment.

                          Subpart N--Landfills

    Source: 47 FR 32365, July 26, 1982, unless otherwise noted.



Sec. 264.300  Applicability.

    The regulations in this subpart apply to owners and operators of 
facilities that dispose of hazardous waste in landfills, except as 
Sec. 264.1 provides otherwise.

[[Page 279]]



Sec. 264.301  Design and operating requirements.

    (a) Any landfill that is not covered by paragraph (c) of this 
section or Sec. 265.301(a) of this chapter must have a liner system for 
all portions of the landfill (except for existing portions of such 
landfill). The liner system must have:
    (1) A liner that is designed, constructed, and installed to prevent 
any migration of wastes out of the landfill to the adjacent subsurface 
soil or ground water or surface water at anytime during the active life 
(including the closure period) of the landfill. The liner must be 
constructed of materials that prevent wastes from passing into the liner 
during the active life of the facility. The liner must be:
    (i) Constructed of materials that have appropriate chemical 
properties and sufficient strength and thickness to prevent failure due 
to pressure gradients (including static head and external hydrogeologic 
forces), physical contact with the waste or leachate to which they are 
exposed, climatic conditions, the stress of installation, and the stress 
of daily operation;
    (ii) Placed upon a foundation or base capable of providing support 
to the liner and resistance to pressure gradients above and below the 
liner to prevent failure of the liner due to settlement, compression, or 
uplift; and
    (iii) Installed to cover all surrounding earth likely to be in 
contact with the waste or leachate; and
    (2) A leachate collection and removal system immediately above the 
liner that is designed, constructed, maintained, and operated to collect 
and remove leachate from the landfill. The Regional Administrator will 
specify design and operating conditions in the permit to ensure that the 
leachate depth over the liner does not exceed 30 cm (one foot). The 
leachate collection and removal system must be:
    (i) Constructed of materials that are:
    (A) Chemically resistant to the waste managed in the landfill and 
the leachate expected to be generated; and
    (B) Of sufficient strength and thickness to prevent collapse under 
the pressures exerted by overlying wastes, waste cover materials, and by 
any equipment used at the landfill; and
    (ii) Designed and operated to function without clogging through the 
scheduled closure of the landfill.
    (b) The owner or operator will be exempted from the requirements of 
paragraph (a) of this section if the Regional Administrator finds, based 
on a demonstration by the owner or operator, that alternative design and 
operating practices, together with location characteristics, will 
prevent the migration of any hazardous constituents (see Sec. 264.93) 
into the ground water or surface water at any future time. In deciding 
whether to grant an exemption, the Regional Administrator will consider:
    (1) The nature and quantity of the wastes;
    (2) The proposed alternate design and operation;
    (3) The hydrogeologic setting of the facility, including the 
attenuative capacity and thickness of the liners and soils present 
between the landfill and ground water or surface water; and
    (4) All other factors which would influence the quality and mobility 
of the leachate produced and the potential for it to migrate to ground 
water or surface water.
    (c) The owner or operator of each new landfill unit on which 
construction commences after January 29, 1992, each lateral expansion of 
a landfill unit on which construction commences after July 29, 1992, and 
each replacement of an existing landfill unit that is to commence reuse 
after July 29, 1992 must install two or more liners and a leachate 
collection and removal system above and between such liners. 
``Construction commences'' is as defined in Sec. 260.10 of this chapter 
under ``existing facility''.
    (1)(i) The liner system must include:
    (A) A top liner designed and constructed of materials (e.g., a 
geomembrane) to prevent the migration of hazardous constituents into 
such liner during the active life and post-closure care period; and
    (B) A composite bottom liner, consisting of at least two components. 
The upper component must be designed and constructed of materials (e.g., 
a geomembrane) to prevent the migration of hazardous constituents into 
this component during the active life and post-closure care period. The 
lower

[[Page 280]]

component must be designed and constructed of materials to minimize the 
migration of hazardous constituents if a breach in the upper component 
were to occur. The lower component must be constructed of at least 3 
feet (91 cm) of compacted soil material with a hydraulic conductivity of 
no more than 1 x 10-7 cm/sec.
    (ii) The liners must comply with paragraphs (a)(1) (i), (ii), and 
(iii) of this section.
    (2) The leachate collection and removal system immediately above the 
top liner must be designed, constructed, operated, and maintained to 
collect and remove leachate from the landfill during the active life and 
post-closure care period. The Regional Administrator will specify design 
and operating conditions in the permit to ensure that the leachate depth 
over the liner does not exceed 30 cm (one foot). The leachate collection 
and removal system must comply with paragraphs (3)(c) (iii) and (iv) of 
this section.
    (3) The leachate collection and removal system between the liners, 
and immediately above the bottom composite liner in the case of multiple 
leachate collection and removal systems, is also a leak detection 
system. This leak detection system must be capable of detecting, 
collecting, and removing leaks of hazardous constituents at the earliest 
practicable time through all areas of the top liner likely to be exposed 
to waste or leachate during the active life and post-closure care 
period. The requirements for a leak detection system in this paragraph 
are satisfied by installation of a system that is, at a minimum:
    (i) Constructed with a bottom slope of one percent or more;
    (ii) Constructed of granular drainage materials with a hydraulic 
conductivity of 1 x 10-2 cm/sec or more and a thickness of 12 
inches (30.5 cm) or more; or constructed of synthetic or geonet drainage 
materials with a transmissivity of 3 x 10-5 m2/sec 
or more;
    (iii) Constructed of materials that are chemically resistant to the 
waste managed in the landfill and the leachate expected to be generated, 
and of sufficient strength and thickness to prevent collapse under the 
pressures exerted by overlying wastes, waste cover materials, and 
equipment used at the landfill;
    (iv) Designed and operated to minimize clogging during the active 
life and post-closure care period; and
    (v) Constructed with sumps and liquid removal methods (e.g., pumps) 
of sufficient size to collect and remove liquids from the sump and 
prevent liquids from backing up into the drainage layer. Each unit must 
have its own sump(s). The design of each sump and removal system must 
provide a method for measuring and recording the volume of liquids 
present in the sump and of liquids removed.
    (4) The owner or operator shall collect and remove pumpable liquids 
in the leak detection system sumps to minimize the head on the bottom 
liner.
    (5) The owner or operator of a leak detection system that is not 
located completely above the seasonal high water table must demonstrate 
that the operation of the leak detection system will not be adversely 
affected by the presence of ground water.
    (d) The Regional Administrator may approve alternative design or 
operating practices to those specified in paragraph (c) of this section 
if the owner or operator demonstrates to the Regional Administrator that 
such design and operating practices, together with location 
characteristics:
    (1) Will prevent the migration of any hazardous constituent into the 
ground water or surface water at least as effectively as the liners and 
leachate collection and removal systems specified in paragraph (c) of 
this section; and
    (2) Will allow detection of leaks of hazardous constituents through 
the top liner at least as effectively.
    (e) The double liner requirement set forth in paragraph (c) of this 
section may be waived by the Regional Administrator for any monofill, 
if:
    (1) The monofill contains only hazardous wastes from foundry furnace 
emission controls or metal casting molding sand, and such wastes do not 
contain constituents which would render the wastes hazardous for reasons 
other than the Toxicity Characteristic in Sec. 261.24 of this chapter, 
with EPA Hazardous Waste Numbers D004 through D017; and

[[Page 281]]

    (2)(i)(A) The monofill has at least one liner for which there is no 
evidence that such liner is leaking;
    (B) The monofill is located more than one-quarter mile from an 
underground source of drinking water (as that term is defined in 
Sec. 144.3 of this chapter); and
    (C) The monofill is in compliance with generally applicable ground-
water monitoring requirements for facilities with permits under RCRA 
3005(c); or
    (ii) The owner or operator demonstrates that the monofill is 
located, designed and operated so as to assure that there will be no 
migration of any hazardous constituent into ground water or surface 
water at any future time.
    (f) The owner or operator of any replacement landfill unit is exempt 
from paragraph (c) of this section if:
    (1) The existing unit was constructed in compliance with the design 
standards of section 3004(o)(1)(A)(i) and (o)(5) of the Resource 
Conservation and Recovery Act; and
    (2) There is no reason to believe that the liner is not functioning 
as designed.
    (g) The owner or operator must design, construct, operate, and 
maintain a run-on control system capable of preventing flow onto the 
active portion of the landfill during peak discharge from at least a 25-
year storm.
    (h) The owner or operator must design, construct, operate, and 
maintain a run-off management system to collect and control at least the 
water volume resulting from a 24-hour, 25-year storm.
    (i) Collection and holding facilities (e.g., tanks or basins) 
associated with run-on and run-off control systems must be emptied or 
otherwise managed expeditiously after storms to maintain design capacity 
of the system.
    (j) If the landfill contains any particulate matter which may be 
subject to wind dispersal, the owner or operator must cover or otherwise 
manage the landfill to control wind dispersal.
    (k) The Regional Administrator will specify in the permit all design 
and operating practices that are necessary to ensure that the 
requirements of this section are satisfied.
    (l) Any permit under RCRA 3005(c) which is issued for a landfill 
located within the State of Alabama shall require the installation of 
two or more liners and a leachate collection system above and between 
such liners, notwithstanding any other provision of RCRA.

FR 28748, July 15, 1985; 55 FR 11875, Mar. 29, 1990; 57 FR 3489, Jan. 
29, 1992]



Sec. 264.302  Action leakage rate.

    (a) The Regional Administrator shall approve an action leakage rate 
for surface impoundment units subject to Sec. 264.301(c) or (d). The 
action leakage rate is the maximum design flow rate that the leak 
detection system (LDS) can remove without the fluid head on the bottom 
liner exceeding l foot. The action leakage rate must include an adequate 
safety margin to allow for uncertainties in the design (e.g., slope, 
hydraulic conductivity, thickness of drainage material), construction, 
operation, and location of the LDS, waste and leachate characteristics, 
likelihood and amounts of other sources of liquids in the LDS, and 
proposed response actions (e.g., the action leakage rate must consider 
decreases in the flow capacity of the system over time resulting from 
siltation and clogging, rib layover and creep of synthetic components of 
the system, overburden pressures, etc.).
    (b) To determine if the action leakage rate has been exceeded, the 
owner or operator must convert the weekly or monthly flow rate from the 
monitoring data obtained under Sec. 264.303(c), to an average daily flow 
rate (gallons per acre per day) for each sump. Unless the Regional 
Administrator approves a different calculation, the average daily flow 
rate for each sump must be calculated weekly during the active life and 
closure period, and monthly during the post-closure care period when 
monthly monitoring is required under Sec. 264.303(c).

[57 FR 3490, Jan. 29, 1992]



Sec. 264.303  Monitoring and inspection.

    (a) During construction or installation, liners (except in the case 
of existing portions of landfills exempt from Sec. 264.301(a)) and cover 
systems (e.g.,

[[Page 282]]

membranes, sheets, or coatings) must be inspected for uniformity, 
damage, and imperfections (e.g., holes, cracks, thin spots, or foreign 
materials). Immediately after construction or installation:
    (1) Synthetic liners and covers must be inspected to ensure tight 
seams and joints and the absence of tears, punctures, or blisters; and
    (2) Soil-based and admixed liners and covers must be inspected for 
imperfections including lenses, cracks, channels, root holes, or other 
structural non-uniformities that may cause an increase in the 
permeability of the liner or cover.
    (b) While a landfill is in operation, it must be inspected weekly 
and after storms to detect evidence of any of the following:
    (1) Deterioration, malfunctions, or improper operation of run-on and 
run-off control systems;
    (2) Proper functioning of wind dispersal control systems, where 
present; and
    (3) The presence of leachate in and proper functioning of leachate 
collection and removal systems, where present.
    (c)(1) An owner or operator required to have a leak detection system 
under Sec. 264.301(c) or (d) must record the amount of liquids removed 
from each leak detection system sump at least once each week during the 
active life and closure period.
    (2) After the final cover is installed, the amount of liquids 
removed from each leak detection system sump must be recorded at least 
monthly. If the liquid level in the sump stays below the pump operating 
level for two consecutive months, the amount of liquids in the sumps 
must be recorded at least quarterly. If the liquid level in the sump 
stays below the pump operating level for two consecutive quarters, the 
amount of liquids in the sumps must be recorded at least semi-annually. 
If at any time during the post-closure care period the pump operating 
level is exceeded at units on quarterly or semi-annual recording 
schedules, the owner or operator must return to monthly recording of 
amounts of liquids removed from each sump until the liquid level again 
stays below the pump operating level for two consecutive months.
    (3) ``Pump operating level'' is a liquid level proposed by the owner 
or operator and approved by the Regional Administrator based on pump 
activation level, sump dimensions, and level that avoids backup into the 
drainage layer and minimizes head in the sump.

Sec. 264.304  Response actions.

    (a) The owner or operator of landfill units subject to 
Sec. 264.301(c) or (d) must have an approved response action plan before 
receipt of waste. The response action plan must set forth the actions to 
be taken if the action leakage rate has been exceeded. At a minimum, the 
response action plan must describe the actions specified in paragraph 
(b) of this section.
    (b) If the flow rate into the leak detection system exceeds the 
action leakage rate for any sump, the owner or operator must:
    (1) Notify the Regional Administrator in writing of the exceedence 
within 7 days of the determination;
    (2) Submit a preliminary written assessment to the Regional 
Administrator within 14 days of the determination, as to the amount of 
liquids, likely sources of liquids, possible location, size, and cause 
of any leaks, and short-term actions taken and planned;
    (3) Determine to the extent practicable the location, size, and 
cause of any leak;
    (4) Determine whether waste receipt should cease or be curtailed, 
whether any waste should be removed from the unit for inspection, 
repairs, or controls, and whether or not the unit should be closed;
    (5) Determine any other short-term and longer-term actions to be 
taken to mitigate or stop any leaks; and
    (6) Within 30 days after the notification that the action leakage 
rate has been exceeded, submit to the Regional Administrator the results 
of the analyses specified in paragraphs (b)(3), (4), and (5) of this 
section, the results of actions taken, and actions planned. Monthly 
thereafter, as long as the flow rate in the leak detection system 
exceeds the action leakage rate, the owner or operator must submit to 
the

[[Page 283]]

Regional Administrator a report summarizing the results of any remedial 
actions taken and actions planned.
    (c) To make the leak and/or remediation determinations in paragraphs 
(b)(3), (4), and (5) of this section, the owner or operator must:
    (1)(i) Assess the source of liquids and amounts of liquids by 
source,
    (ii) Conduct a fingerprint, hazardous constituent, or other analyses 
of the liquids in the leak detection system to identify the source of 
liquids and possible location of any leaks, and the hazard and mobility 
of the liquid; and
    (iii) Assess the seriousness of any leaks in terms of potential for 
escaping into the environment; or
    (2) Document why such assessments are not needed.

landfilled without meeting the requirements of paragraph (a) of this 
section, provided that the wastes are disposed of in such a way that 
they are protected from any material or conditions which may cause them 
to ignite. At a minimum, ignitable wastes must be disposed of in non-
leaking containers which are carefully handled and placed so as to avoid 
heat, sparks, rupture, or any other condition that might cause ignition 
of the wastes; must be covered daily with soil or other non-combustible 
material to minimize the potential for ignition of the wastes; and must 
not be disposed of in cells that contain or will contain other wastes 
which may generate heat sufficient to cause ignition of the waste.

under OECD test 301B: [CO2 Evolution (Modified Sturm Test)].
    (f) Effective November 8, 1985, the placement of any liquid which is 
not a hazardous waste in a landfill is prohibited unless the owner or 
operator of such landfill demonstrates to the Regional Administrator, or 
the Regional Administrator determines, that:
    (1) The only reasonably available alternative to the placement in 
such landfill is placement in a landfill or unlined surface impoundment, 
whether or not permitted or operating under interim status, which 
contains, or may reasonably be anticipated to contain, hazardous waste; 
and
    (2) Placement in such owner or operator's landfill will not present 
a risk of contamination of any underground source of drinking water (as 
that term is defined in Sec. 144.3 of this chapter.)

Sec. 264.315  Special requirements for containers.

    Unless they are very small, such as an ampule, containers must be 
either:
    (a) At least 90 percent full when placed in the landfill; or
    (b) Crushed, shredded, or similarly reduced in volume to the maximum 
practical extent before burial in the landfill.



Sec. 264.316  Disposal of small containers of hazardous waste in overpacked drums (lab packs).

    Small containers of hazardous waste in overpacked drums (lab packs) 
may be placed in a landfill if the following requirements are met:
    (a) Hazardous waste must be packaged in non-leaking inside 
containers. The inside containers must be of a design and constructed of 
a material that will not react dangerously with, be decomposed by, or be 
ignited by the contained waste. Inside containers must be tightly and 
securely sealed. The inside containers must be of the size and type 
specified in the Department of Transportation (DOT) hazardous materials 
regulations (49 CFR parts 173, 178, and 179), if those regulations 
specify a particular inside container for the waste.
    (b) The inside containers must be overpacked in an open head DOT-
specification metal shipping container (49 CFR parts 178 and 179) of no 
more than 416-liter (110 gallon) capacity and surrounded by, at a 
minimum, a sufficient quantity of sorbent material, determined to be 
nonbiodegradable in accordance with Sec. 264.314(e), to completely sorb 
all of the liquid contents of the inside containers. The metal outer 
container must be full after it has been packed with inside containers 
and sorbent material.
    (c) The sorbent material used must not be capable of reacting 
dangerously with, being decomposed by, or being ignited by the contents 
of the inside containers, in accordance with Sec. 264.17(b).
    (d) Incompatible wastes, as defined in Sec. 260.10 of this chapter, 
must not be placed in the same outside container.
    (e) Reactive wastes, other than cyanide- or sulfide-bearing waste as 
defined in Sec. 261.23(a)(5) of this chapter, must be treated or 
rendered non-reactive prior to packaging in accordance with paragraphs 
(a) through (d) of this section. Cyanide- and sulfide-bearing reactive 
waste may be packed in accordance with paragraphs (a) through (d) of 
this section without first being treated or rendered non-reactive.
    (f) Such disposal is in compliance with the requirements of part 
268. Persons who incinerate lab packs according to the requirements in 
40 CFR 268.42(c)(1) may use fiber drums in place of metal outer 
containers. Such

[[Page 286]]

fiber drums must meet the DOT specifications in 49 CFR 173.12 and be 
overpacked according to the requirements in paragraph (b) of this 
section.

Sec. 264.317  Special requirements for hazardous wastes FO20, FO21, FO22, FO23, FO26, and FO27.

    (a) Hazardous Wastes FO20, FO21, FO22, FO23, FO26, and FO27 must not 
be placed in a landfills unless the owner or operator operates the 
landfill in accord with a management plan for these wastes that is 
approved by the Regional Administrator pursuant to the standards set out 
in this paragraph, and in accord with all other applicable requirements 
of this part. The factors to be considered are:
    (1) The volume, physical, and chemical characteristics of the 
wastes, including their potential to migrate through the soil or to 
volatilize or escape into the atmosphere;
    (2) The attenuative properties of underlying and surrounding soils 
or other materials;
    (3) The mobilizing properties of other materials co-disposed with 
these wastes; and
    (4) The effectiveness of additional treatment, design, or monitoring 
requirements.
    (b) The Regional Administrator may determine that additional design, 
operating, and monitoring requirements are necessary for landfills 
managing hazardous wastes FO20, FO21, FO22, FO23, FO26, and FO27 in 
order to reduce the possibility of migration of these wastes to ground 
water, surface water, or air so as to protect human health and the 
environment.

                         Subpart O--Incinerators



Sec. 264.340  Applicability.

    (a) The regulations of this subpart apply to owners and operators of 
hazardous waste incinerators (as defined in Sec. 260.10 of this 
chapter), except as Sec. 264.1 provides otherwise.
    (b) After consideration of the waste analysis included with part B 
of the permit application, the Regional Administrator, in establishing 
the permit conditions, must exempt the applicant from all requirements 
of this subpart except Sec. 264.341 (Waste analysis) and Sec. 264.351 
(Closure),
    (1) If the Regional Administrator finds that the waste to be burned 
is:
    (i) Listed as a hazardous waste in part 261, subpart D, of this 
chapter solely because it is ignitable (Hazard Code I), corrosive 
(Hazard Code C), or both; or
    (ii) Listed as a hazardous waste in part 261, subpart D, of this 
chapter solely because it is reactive (Hazard Code R) for 
characteristics other than those listed in Sec. 261.23(a) (4) and (5), 
and will not be burned when other hazardous wastes are present in the 
combustion zone; or
    (iii) A hazardous waste solely because it possesses the 
characteristic of ignitability, corrosivity, or both, as determined by 
the test for characteristics of hazardous wastes under part 261, subpart 
C, of this chapter; or
    (iv) A hazardous waste solely because it possesses any of the 
reactivity characteristics described by Sec. 261.23(a) (1), (2), (3), 
(6), (7), and (8) of this chapter, and will not be burned when other 
hazardous wastes are present in the combustion zone; and
    (2) If the waste analysis shows that the waste contains none of the 
hazardous constituents listed in part 261, appendix VIII, of this 
chapter, which would reasonably be expected to be in the waste.
    (c) If the waste to be burned is one which is described by 
paragraphs (b)(1)(i), (ii), (iii), or (iv) of this section and contains 
insignificant concentrations of the hazardous constituents listed in 
part 261, appendix VIII, of this chapter, then the Regional 
Administrator may, in establishing permit conditions, exempt the 
applicant from all requirements of this subpart, except Sec. 264.341 
(Waste analysis) and Sec. 264.351 (Closure), after consideration of the 
waste analysis included with part B of the permit application, unless 
the Regional Administrator finds that the waste will pose a threat to 
human health and the environment when burned in an incinerator.

Sec. 264.341  Waste analysis.

    (a) As a portion of the trial burn plan required by Sec. 270.62 of 
this chapter, or with part B of the permit application, the owner or 
operator must have included an analysis of the waste feed sufficient to 
provide all information required by Sec. 270.62(b) or Sec. 270.19 of 
this chapter. Owners or operators of new hazardous waste incinerators 
must provide the information required by Sec. 270.62(c) or Sec. 270.19 
of this chapter to the greatest extent possible.
    (b) Throughout normal operation the owner or operator must conduct 
sufficient waste analysis to verify that waste feed to the incinerator 
is within the physical and chemical composition limits specified in his 
permit (under Sec. 264.345(b)).

Sec. 264.342  Principal organic hazardous constituents (POHCs).

    (a) Principal Organic Hazardous Constituents (POHCs) in the waste 
feed must be treated to the extent required by the performance standard 
of Sec. 264.343.
    (b)(1) One or more POHCs will be specified in the facility's permit, 
from among those constituents listed in part 261, appendix VIII of this 
chapter, for each waste feed to be burned. This specification will be 
based on the degree of difficulty of incineration of the organic 
constituents in the waste and on their concentration or mass in the 
waste feed, considering the results of waste analyses and trial burns or 
alternative data submitted with part B of the facility's permit 
application. Organic constituents which represent the greatest degree of 
difficulty of incineration will be those most likely to be designated as 
POHCs. Constituents are more likely to be designated as POHCs if they 
are present in large quantities or concentrations in the waste.
    (2) Trial POHCs will be designated for performance of trial burns in 
accordance with the procedure specified in Sec. 270.62 of this chapter 
for obtaining trial burn permits.

Sec. 264.343  Performance standards.

    An incinerator burning hazardous waste must be designed, 
constructed, and maintained so that, when operated in accordance with 
operating requirements specified under Sec. 264.345, it will meet the 
following performance standards:
    (a)(1) Except as provided in paragraph (a)(2) of this section, an 
incinerator burning hazardous waste must achieve a destruction and 
removal efficiency (DRE) of 99.99% for each principal organic hazardous 
constituent (POHC) designated (under Sec. 264.342) in its permit for 
each waste feed. DRE is determined for each POHC from the following 
equation:

                                                                                                                
                                                         (Win-Wout)                                             
                                               DRE=   ----------------    x 100%                                
                                                             Win                                                
                                                                                                                

where:

Win=mass feed rate of one principal organic hazardous 
          constituent (POHC) in the waste stream feeding the incinerator

and

Wout=mass emission rate of the same POHC present in exhaust 
          emissions prior to release to the atmosphere.

    (2) An incinerator burning hazardous wastes FO20, FO21, FO22, FO23, 
FO26, or FO27 must achieve a destruction and removal efficiency (DRE) of 
99.9999% for each principal organic hazardous constituent (POHC) 
designated (under Sec. 264.342) in its permit. This performance must be 
demonstrated on POHCs that are more difficult to incinerate than tetra-, 
penta-, and hexachlorodibenzo-p-dioxins and dibenzofurans. DRE is 
determined for each POHC from the equation in Sec. 264.343(a)(1). In 
addition, the owner or operator of the incinerator must notify

[[Page 288]]

the Regional Administrator of his intent to incinerate hazardous wastes 
FO20, FO21, FO22, FO23, FO26, or FO27.
    (b) An incinerator burning hazardous waste and producing stack 
emissions of more than 1.8 kilograms per hour (4 pounds per hour) of 
hydrogen chloride (HCl) must control HCl emissions such that the rate of 
emission is no greater than the larger of either 1.8 kilograms per hour 
or 1% of the HCl in the stack gas prior to entering any pollution 
control equipment.
    (c) An incinerator burning hazardous waste must not emit particulate 
matter in excess of 180 milligrams per dry standard cubic meter (0.08 
grains per dry standard cubic foot) when corrected for the amount of 
oxygen in the stack gas according to the formula:

Where Pc is the corrected concentration of particulate 
matter, Pm is the measured concentration of particulate 
matter, and Y is the measured concentration of oxygen in the stack gas, 
using the Orsat method for oxygen analysis of dry flue gas, presented in 
part 60, appendix A (Method 3), of this chapter. This correction 
procedure is to be used by all hazardous waste incinerators except those 
operating under conditions of oxygen enrichment. For these facilities, 
the Regional Administrator will select an appropriate correction 
procedure, to be specified in the facility permit.
    (d) For purposes of permit enforcement, compliance with the 
operating requirements specified in the permit (under Sec. 264.345) will 
be regarded as compliance with this section. However, evidence that 
compliance with those permit conditions is insufficient to ensure 
compliance with the performance requirements of this section may be 
``information'' justifying modification, revocation, or reissuance of a 
permit under Sec. 270.41 of this chapter.

Sec. 264.344  Hazardous waste incinerator permits.

    (a) The owner or operator of a hazardous waste incinerator may burn 
only wastes specified in his permit and only under operating conditions 
specified for those wastes under Sec. 264.345, except:
    (1) In approved trial burns under Sec. 270.62 of this chapter; or
    (2) Under exemptions created by Sec. 264.340.
    (b) Other hazardous wastes may be burned only after operating 
conditions have been specified in a new permit or a permit modification 
as applicable. Operating requirements for new wastes may be be based on 
either trial burn results or alternative data included with part B of a 
permit application under Sec. 270.19 of this chapter.
    (c) The permit for a new hazardous waste incinerator must establish 
appropriate conditions for each of the applicable requirements of this 
subpart, including but not limited to allowable waste feeds and 
operating conditions necessary to meet the requirements of Sec. 264.345, 
sufficient to comply with the following standards:
    (1) For the period beginning with initial introduction of hazardous 
waste to the incinerator and ending with initiation of the trial burn, 
and only for the minimum time required to establish operating conditions 
required in paragraph (c)(2) of this section, not to exceed a duration 
of 720 hours operating time for treatment of hazardous waste, the 
operating requirements must be those most likely to ensure compliance 
with the performance standards of Sec. 264.343, based on the Regional 
Administrator's engineering judgment. The Regional Administrator may 
extend the duration of this period once for up to 720 additional hours 
when good cause for the extension is demonstrated by the applicant.
    (2) For the duration of the trial burn, the operating requirements 
must be sufficient to demonstrate compliance with the performance 
standards of Sec. 264.343 and must be in accordance with the approved 
trial burn plan;
    (3) For the period immediately following completion of the trial 
burn, and only for the minimum period sufficient to allow sample 
analysis, data

computation, and submission of the trial burn results by the applicant, 
and review of the trial burn results and modification of the facility 
permit by the Regional Administrator, the operating requirements must be 
those most likely to ensure compliance with the performance standards of 
Sec. 264.343, based on the Regional Administrator's engineering 
judgement.
    (4) For the remaining duration of the permit, the operating 
requirements must be those demonstrated, in a trial burn or by 
alternative data specified in Sec. 270.19(c) of this chapter, as 
sufficient to ensure compliance with the performance standards of 
Sec. 264.343.

Sec. 264.345  Operating requirements.

    (a) An incinerator must be operated in accordance with operating 
requirements specified in the permit. These will be specified on a case-
by-case basis as those demonstrated (in a trial burn or in alternative 
data as specified in Sec. 264.344(b) and included with part B of a 
facility's permit application) to be sufficient to comply with the 
performance standards of Sec. 264.343.
    (b) Each set of operating requirements will specify the composition 
of the waste feed (including acceptable variations in the physical or 
chemical properties of the waste feed which will not affect compliance 
with the performance requirement of Sec. 264.343) to which the operating 
requirements apply. For each such waste feed, the permit will specify 
acceptable operating limits including the following conditions:
    (1) Carbon monoxide (CO) level in the stack exhaust gas;
    (2) Waste feed rate;
    (3) Combustion temperature;
    (4) An appropriate indicator of combustion gas velocity;
    (5) Allowable variations in incinerator system design or operating 
procedures; and
    (6) Such other operating requirements as are necessary to ensure 
that the performance standards of Sec. 264.343 are met.
    (c) During start-up and shut-down of an incinerator, hazardous waste 
(except wastes exempted in accordance with Sec. 264.340) must not be fed 
into the incinerator unless the incinerator is operating within the 
conditions of operation (temperature, air feed rate, etc.) specified in 
the permit.
    (d) Fugitive emissions from the combustion zone must be controlled 
by:
    (1) Keeping the combustion zone totally sealed against fugitive 
emissions; or
    (2) Maintaining a combustion zone pressure lower than atmospheric 
pressure; or
    (3) An alternate means of control demonstrated (with part B of the 
permit application) to provide fugitive emissions control equivalent to 
maintenance of combustion zone pressure lower than atmospheric pressure.
    (e) An incinerator must be operated with a functioning system to 
automatically cut off waste feed to the incinerator when operating 
conditions deviate from limits established under paragraph (a) of this 
section.
    (f) An incinerator must cease operation when changes in waste feed, 
incinerator design, or operating conditions exceed limits designated in 
its permit.

[[Page 290]]

    (b) The incinerator and associated equipment (pumps, valves, 
conveyors, pipes, etc.) must be subjected to thorough visual inspection, 
at least daily, for leaks, spills, fugitive emissions, and signs of 
tampering.
    (c) The emergency waste feed cutoff system and associated alarms 
must be tested at least weekly to verify operability, unless the 
applicant demonstrates to the Regional Administrator that weekly 
inspections will unduly restrict or upset operations and that less 
frequent inspection will be adequate. At a minimum, operational testing 
must be conducted at least monthly.
    (d) This monitoring and inspection data must be recorded and the 
records must be placed in the operating log required by Sec. 264.73.

Sec. 264.570  Applicability.

    (a) The requirements of this subpart apply to owners and operators 
of facilities that use new or existing drip pads to convey treated wood 
drippage, precipitation, and/or surface water run-off to an associated 
collection system. Existing drip pads are those constructed before 
December 6, 1990 and those for which the owner or operator has a design 
and has entered into binding financial or other agreements for 
construction prior to December 6, 1990. All other drip pads are new drip 
pads. The requirement at Sec. 264.573(b)(3) to install a leak collection 
system applies only to those drip pads that are constructed after 
December 24, 1992 except for those constructed after December 24, 1992 
for which the owner or operator has a design and has entered into 
binding financial or other agreements for construction prior to December 
24, 1992.
    (b) The owner or operator of any drip pad that is inside or under a 
structure

[[Page 293]]

that provides protection from precipitation so that neither run-off nor 
run-on is generated is not subject to regulation under Sec. 264.573(e) 
or Sec. 264.573(f), as appropriate.
    (c) The requirements of this subpart are not applicable to the 
management of infrequent and incidental drippage in storage yards

Sec. 264.571  Assessment of existing drip pad integrity.

    (a) For each existing drip pad as defined in Sec. 264.570 of this 
subpart, the owner or operator must evaluate the drip pad and determine 
that it meets all of the requirements of this subpart, except the 
requirements for liners and leak detection systems of Sec. 264.573(b). 
No later than the effective date of this rule, the owner or operator 
must obtain and keep on file at the facility a written assessment of the 
drip pad, reviewed and certified by an independent, qualified registered 
professional engineer that attests to the results of the evaluation. The 
assessment must be reviewed, updated and re-certified annually until all 
upgrades, repairs, or modifications necessary to achieve compliance with 
all of the standards of Sec. 264.573 of this subpart are complete. The 
evaluation must document the extent to which the drip pad meets each of 
the design and operating standards of Sec. 264.573 of this subpart, 
except the standards for liners and leak detection systems, specified in 
Sec. 264.573(b) of this subpart.
    (b) The owner or operator must develop a written plan for upgrading, 
repairing, and modifying the drip pad to meet the requirements of 
Sec. 264.573(b) of this subpart, and submit the plan to the Regional 
Administrator no later than 2 years before the date that all repairs, 
upgrades, and modifications are complete. This written plan must 
describe all changes to be made to the drip pad in sufficient detail to 
document compliance with all the requirements of Sec. 264.573 of this 
subpart. The plan must be reviewed and certified by an independent 
qualified registered professional engineer.
    (c) Upon completion of all upgrades, repairs, and modifications, the 
owner or operator must submit to the Regional Administrator or State 
Director, the as-built drawings for the drip pad together with a 
certification by an independent qualified registered professional 
engineer attesting that the drip pad conforms to the drawings.
    (d) If the drip pad is found to be leaking or unfit for use, the 
owner or operator must comply with the provisions of Sec. 264.573 (m) of 
this subpart or close the drip pad in accordance with Sec. 264.575 of 
this subpart.

Sec. 264.572  Design and installation of new drip pads.

    Owners and operators of new drip pads must ensure that the pads are 
designed, installed, and operated in accordance with one of the 
following:
    (a) all of the requirements of Secs. 264.573 (except 264.573(a)(4)), 
264.574 and 264.575 of this subpart, or
    (b) all of the requirements of Secs. 264.573 (except 
Sec. 264.573(b)), 264.574 and 264.575 of this subpart.

[57 FR 61503, Dec. 24, 1992]



Sec. 264.573  Design and operating requirements.

    (a) Drip pads must: (1) Be constructed of non-earthern materials, 
excluding wood and non-structurally supported asphalt:
    (2) Be sloped to free-drain treated wood drippage, rain and other 
waters, or solutions of drippage and water or

[[Page 294]]

other wastes to the associated collection system;
    (3) Have a curb or berm around the perimeter;
    (4)(i) Have a hydraulic conductivity of less than or equal to 
1 x 10-\7\ centimeters per second, e.g., existing concrete drip pads 
must be sealed, coated, or covered with a surface material with a 
hydraulic conductivity of less than or equal to 1 x 10-\7\ centimeters 
per second such that the entire surface where drippage occurs or may run 
across is capable of containing such drippage and mixtures of drippage 
and precipitation, materials, or other wastes while being routed to an 
associated collection system. This surface material must be maintained 
free of cracks and gaps that could adversely affect its hydraulic 
conductivity, and the material must be chemically compatible with the 
preservatives that contact the drip pad. The requirements of this 
provision apply only to existing drip pads and those drip pads for which 
the owner or operator elects to comply with Sec. 264.572(a) instead of 
Sec. 264.572(b).
    (ii) The owner or operator must obtain and keep on file at the 
facility a written assessment of the drip pad, reviewed and certified by 
an independent, qualified registered professional engineer that attests 
to the results of the evaluation. The assessment must be reviewed, 
updated and recertified annually. The evaluation must document the 
extent to which the drip pad meets the design and operating standards of 
this section, except for paragraph (b) of this Section.
    (5) Be of sufficient structural strength and thickness to prevent 
failure due to physical contact, climatic conditions, the stress of 
daily perations, e.g., variable and moving loads such as vehicle 
traffic, movement of wood, etc.

    Note: EPA will generally consider applicable standards established 
by professional organizations generally recognized by the industry such 
as the American Concrete Institute (ACI) or the American Society of 
Testing and Materials (ASTM) in judging the structural integrity 
requirement of this paragraph.

    (b) If an owner/operator elects to comply with Sec. 264.572(b) 
instead of Sec. 264.572(a), the drip pad must have:
    (1) A synthetic liner installed below the drip pad that is designed, 
constructed, and installed to prevent leakage from the drip pad into the 
adjacent subsurface soil or groundwater or surface water at any time 
during the active life (including the closure period) of the drip pad. 
The liner must be constructed of materials that will prevent waste from 
being absorbed into the liner and to prevent releases into the adjacent 
subsurface soil or groundwater or surface water during the active life 
of the facility. The liner must be:
    (i) Constructed of materials that have appropriate chemical 
properties and sufficient strength and thickness to prevent failure due 
to pressure gradients (including static head and external hydrogeologic 
forces), physical contact with the waste or drip pad leakage to which 
they are exposed, climatic conditions, the stress of installation, and 
the stress of daily operation (including stresses from vehicular traffic 
on the drip pad);
    (ii) Placed upon a foundation or base capable of providing support 
to the liner and resistance to pressure gradients above and below the 
liner to prevent failure of the liner due to settlement, compression or 
uplift; and
    (iii) Installed to cover all surrounding earth that could come in 
contact with the waste or leakage; and
    (2) A leakage detection system immediately above the liner that is 
designed, constructed, maintained and operated to detect leakage from 
the drip pad. The leakage detection system must be:
    (i) Constructed of materials that are:
    (A) Chemically resistant to the waste managed in the drip pad and 
the leakage that might be generated; and
    (B) Of sufficient strength and thickness to prevent collapse under 
the pressures exerted by overlaying materials and by any equipment used 
at the drip pad;
    (ii) Designed and operated to function without clogging through the 
scheduled closure of the drip pad; and
    (iii) Designed so that it will detect the failure of the drip pad or 
the presence of a release of hazardous waste or accumulated liquid at 
the earliest practicable time.

[[Page 295]]

    (3) A leakage collection system immediately above the liner that is 
designed, constructed, maintained and operated to collect leakage from 
the drip pad such that it can be removed from below the drip pad. The 
date, time, and quantity of any leakage collected in this system and 
removed must be documented in the operating log.
    (c) Drip pads must be maintained such that they remain free of 
cracks, gaps, corrosion, or other deterioration that could cause 
hazardous waste to be released from the drip pad.

    Note: See Sec. 264.573(m) for remedial action required if 
deterioration or leakage is detected.

    (d) The drip pad and associated collection system must be designed 
and operated to convey, drain, and collect liquid resulting from 
drippage or precipitation in order to prevent run-off.
    (e) Unless protected by a structure, as described in Sec. 264.570(b) 
of this subpart, the owner or operator must design, construct, operate 
and maintain a run-on control system capable of preventing flow onto the 
drip pad during peak discharge from at least a 24-hour, 25-year storm, 
unless the system has sufficient excess capacity to contain any run-off 
that might enter the system.
    (f) Unless protected by a structure or cover as described in 
Sec. 264.570(b) of this subpart, the owner or operator must design, 
construct, operate and maintain a run-off management system to collect 
and control at least the water volume resulting from a 24-hour, 25-year 
storm.
    (g) The drip pad must be evaluated to determine that it meets the 
requirements of paragraphs (a) through (f) of this section and the owner

drip pad.
    (i) The drip pad surface must be cleaned thoroughly in a manner and 
frequency such that accumulated residues of hazardous waste or other 
materials are removed, with residues being properly managed as hazardous 
waste, so as to allow weekly inspections of the entire drip pad surface 
without interference or hindrance from accumulated residues of hazardous 
waste or other materials on the drip pad. The owner or operator must 
document the date and time of each cleaning and the cleaning procedure 
used in the facility's operating log. The owner/operator must determine 
if the residues are hazardous as per 40 CFR 262.11 and, if so, must 
manage them under parts 261-268, 270, and section 3010 of RCRA.
    (j) Drip pads must be operated and maintained in a manner to 
minimize tracking of hazardous waste or hazardous waste constituents off 
the drip pad as a result of activities by personnel or equipment.
    (k) After being removed from the treatment vessel, treated wood from 
pressure and non-pressure processes must be held on the drip pad until 
drippage has ceased. The owner or operator must maintain records 
sufficient to document that all treated wood is held on the pad 
following treatment in accordance with this requirement.
    (l) Collection and holding units associated with run-on and run-off 
control systems must be emptied or otherwise managed as soon as possible 
after storms to maintain design capacity of the system.
    (m) Throughout the active life of the drip pad and as specified in 
the permit, if the owner or operator detects a condition that may have 
caused or has caused a release of hazardous waste, the condition must be 
repaired within a reasonably prompt period of time following discovery, 
in accordance with the following procedures:
    (1) Upon detection of a condition that may have caused or has caused 
a release of hazardous waste (e.g., upon detection of leakage in the 
leak detection system), the owner or operator must:
    (i) Enter a record of the discovery in the facility operating log;
    (ii) Immediately remove the portion of the drip pad affected by the 
condition from service;
    (iii) Determine what steps must be taken to repair the drip pad and 
clean

[[Page 296]]

up any leakage from below the drip pad, and establish a schedule for 
accomplishing the repairs;
    (iv) Within 24 hours after discovery of the condition, notify the 
Regional Administrator of the condition and, within 10 working days, 
provide written notice to the Regional Administrator with a description 
of the steps that will be taken to repair the drip pad and clean up any 
leakage, and the schedule for accomplishing this work.
    (2) The Regional Administrator will review the information 
submitted, make a determination regarding whether the pad must be 
removed from service completely or partially until repairs and clean up 
are complete and notify the owner or operator of the determination and 
the underlying rationale in writing.
    (3) Upon completing all repairs and clean up, the owner or operator 
must notify the Regional Administrator in writing and provide a 
certification signed by an independent, qualified registered 
professional engineer, that the repairs and clean up have been completed 
according to the written plan submitted in accordance with paragraph 
(m)(1)(iv) of this section.
    (n) Should a permit be necessary, the Regional Administrator will 
specify in the permit all design and operating practices that are 
necessary to ensure that the requirements of this section are satisfied.
    (o) The owner or operator must maintain, as part of the facility 
operating log, documentation of past operating and waste handling 
practices. This must include identification of preservative formulations 
used in the past, a description of drippage management practices, and a 
description of treated wood storage and handling practices.

Sec. 264.574  Inspections.

    (a) During construction or installation, liners and cover systems 
(e.g., membranes, sheets, or coatings) must be inspected for uniformity, 
damage and imperfections (e.g., holes, cracks, thin spots, or foreign 
materials). Immediately after construction or installation, liners must 
be inspected and certified as meeting the requirements of Sec. 264.573 
of this subpart by an independent qualified, registered professional 
engineer. This certification must be maintained at the facility as part 
of the facility operating record. After installation, liners and covers 
must be inspected to ensure tight seams and joints and the absence of 
tears, punctures, or blisters.
    (b) While a drip pad is in operation, it must be inspected weekly 
and after storms to detect evidence of any of the following:
    (1) Deterioration, malfunctions or improper operation of run-on and 
run-off control systems;
    (2) The presence of leakage in and proper functioning of leak 
detection system.
    (3) Deterioration or cracking of the drip pad surface.

    Note: See Sec. 264.573(m) for remedial action required if 
deterioration or leakage is detected.



Sec. 264.575  Closure.

    (a) At closure, the owner or operator must remove or decontaminate 
all waste residues, contaminated containment system components (pad, 
liners, etc.), contaminated subsoils, and structures and equipment 
contaminated with waste and leakage, and manage them as hazardous waste.
    (b) If, after removing or decontaminating all residues and making 
all reasonable efforts to effect removal or decontamination of 
contaminated components, subsoils, structures, and equipment as required 
in paragraph (a) of this section, the owner or operator finds that not 
all contaminated subsoils can be practicably removed or decontaminated, 
he must close the facility and perform post-closure care in accordance 
with closure and post-closure care requirements that apply to landfills 
(Sec. 264.310). For permitted units, the requirement to have a permit 
continues throughout the post-closure period. In addition, for the 
purpose of closure, post-closure, and financial responsibility, such a 
drip pad is then considered to be landfill, and the owner or operator 
must meet all of the requirements

[[Page 297]]

for landfills specified in subparts G and H of this part.
    (c)(1) The owner or operator of an existing drip pad, as defined in 
Sec. 264.570 of this subpart, that does not comply with the liner 
requirements of Sec. 264.573(b)(1) must:
    (i) Include in the closure plan for the drip pad under Sec. 264.112 
both a plan for complying with paragraph (a) of this section and a 
contingent plan for complying with paragraph (b) of this section in case 
not all contaminated subsoils can be practicably removed at closure; and
    (ii) Prepare a contingent post-closure plan under Sec. 264.118 of 
this part for complying with paragraph (b) of this section in case not 
all contaminated subsoils can be practicably removed at closure.
    (2) The cost estimates calculated under Secs. 264.112 and 264.144 of 
this part for closure and post-closure care of a drip pad subject to 
this paragraph must include the cost of complying with the contingent 
closure plan and the contingent post-closure plan, but are not required 
to include the cost of expected closure under paragraph (a) of this 
section.

Sec. 264.1031   Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act and parts 260-266.
    Air stripping operation is a desorption operation employed to 
transfer one or more volatile components from a liquid mixture into a 
gas (air) either with or without the application of heat to the liquid. 
Packed towers, spray towers, and bubble-cap, sieve, or valve-type plate 
towers are among the process configurations used for contacting the air 
and a liquid.
    Bottoms receiver means a container or tank used to receive and 
collect the heavier bottoms fractions of the distillation feed stream 
that remain in the liquid phase.
    Closed-vent system means a system that is not open to the atmosphere 
and that is composed of piping, connections, and, if necessary, flow-
inducing devices that transport gas or vapor from a piece or pieces of 
equipment to a control device.
    Condenser means a heat-transfer device that reduces a thermodynamic 
fluid from its vapor phase to its liquid phase.
    Connector means flanged, screwed, welded, or other joined fittings

fittings that are not covered by insulation or other materials that 
prevent location of the fittings.
    Continuous recorder means a data-recording device recording an 
instantaneous data value at least once every 15 minutes.
    Control device means an enclosed combustion device, vapor recovery 
system, or flare. Any device the primary function of which is the

larger storage tanks or other process units.
    Distillation operation means an operation, either batch or 
continuous, separating one or more feed stream(s) into two or more exit 
streams, each exit stream having component concentrations different from 
those in the feed stream(s). The separation is achieved by the 
redistribution of the components between the liquid and vapor phase as 
they approach equilibrium within the distillation unit.

management unit or part of a hazardous waste management unit. An 
unscheduled work practice or operational procedure that stops operation 
of a hazardous waste management unit or part of a hazardous waste 
management unit for less than 24 hours is not a hazardous waste 
management unit shutdown. The use of spare equipment and technically 
feasible bypassing of equipment without stopping operation are not 
hazardous waste management unit shutdowns.
    Hot well means a container for collecting condensate as in a steam 
condenser serving a vacuum-jet or steam-jet ejector.

gas/vapor service or in light liquid service.
    In liqht liquid service means that the piece of equipment contains 
or contacts a waste stream where the vapor pressure of one or more of 
the components in the stream is greater than 0.3 kilopascals (kPa) at 20 
 deg.C, the total concentration of the pure components having a vapor 
pressure greater than 0.3 kPa at 20  deg.C is equal to or greater than 
20 percent by weight, and the fluid is a liquid at operating conditions.

hazardous waste management unit or failure of a hazardous waste 
management unit to operate in a normal or usual manner, so that organic 
emissions are increased.
    Open-ended valve or line means any valve, except pressure relief 
valves, having one side of the valve seat in contact with process fluid 
and one side open to the atmosphere, either directly or through open 
piping.
    Pressure release means the emission of materials resulting from the 
system pressure being greater than the set pressure of the pressure 
relief device.
    Process heater means a device that transfers heat liberated by 
burning fuel to fluids contained in tubes, including all fluids except 
water that are heated to produce steam.
    Process vent means any open-ended pipe or stack that is vented to 
the atmosphere either directly, through a vacuum-producing system, or 
through a tank (e.g., distillate receiver, condenser, bottoms receiver, 
surge control tank, separator tank, or hot well) associated with 
hazardous waste distillation, fractionation, thin-film evaporation, 
solvent extraction, or air or steam stripping operations.
    Repaired means that equipment is adjusted, or otherwise altered, to 
eliminate a leak.
    Sensor means a device that measures a physical quantity or the 
change in a physical quantity, such as temperature, pressure, flow rate, 
pH, or liquid level.

separation in which a solid or solution is contacted with a liquid 
solvent (the two being mutually insoluble) to preferentially

[[Page 301]]

dissolve and transfer one or more components into the solvent.
    Startup means the setting in operation of a hazardous waste 
management unit or control device for any purpose.
    Steam stripping operation means a distillation operation in which 
vaporization of the volatile constituents of a liquid mixture takes 
place by the introduction of steam directly into the charge.
    Surge control tank means a large-sized pipe or storage reservoir 
sufficient to contain the surging liquid discharge of the process tank 
to which it is connected.
    Thin-film evaporation operation means a distillation operation that 
employs a heating surface consisting of a large diameter tube that may 
be either straight or tapered, horizontal or vertical. Liquid is spread 
on the tube wall by a rotating assembly of blades that maintain a close 
clearance from the wall or actually ride on the film of liquid on the 
wall.
    Vapor incinerator means any enclosed combustion device that is used 
for destroying organic compounds and does not extract energy in the form 
of steam or process heat.
    Vented means discharged through an opening, typically an open-ended 
pipe or stack, allowing the passage of a stream of liquids, gases, or 
fumes into the atmosphere. The passage of liquids, gases, or fumes is 
caused by mechanical means such as compressors or vacuum-producing 
systems or by process-related means such as evaporation produced by 
heating and not caused by tank loading and unloading (working losses) or 
by natural means such as diurnal temperature changes.



Sec. 264.1032  Standards: Process vents.

    (a) The owner or operator of a facility with process vents 
associated with distillation, fractionation, thin-film evaporation, 
solvent extraction, or air or steam stripping operations managing 
hazardous wastes with organic concentrations of at least 10 ppmw shall 
either:
    (1) Reduce total organic emissions from all affected process vents 
at the facility below 1.4 kg/h (3 lb/h) and 2.8 Mg/yr (3.1 tons/yr), or
    (2) Reduce, by use of a control device, total organic emissions from 
all affected process vents at the facility by 95 weight percent.
    (b) If the owner or operator installs a closed-vent system and 
control device to comply with the provisions of paragraph (a) of this 
section the closed-vent system and control device must meet the 
requirements of Sec. 264.1033.
    (c) Determinations of vent emissions and emission reductions or 
total organic compound concentrations achieved by add-on control devices 
may be based on engineering calculations or performance tests. If 
performance tests are used to determine vent emissions, emission 
reductions, or total organic compound concentrations achieved by add-on 
control devices, the performance tests must conform with the 
requirements of Sec. 264.1034(c).
    (d) When an owner or operator and the Regional Administrator do not 
agree on determinations of vent emissions and/or emission reductions or 
total organic compound concentrations achieved by add-on control devices 
based on engineering calculations, the procedures in Sec. 264.1034(c) 
shall be used to resolve the disagreement.



Sec. 264.1033  Standards: Closed-vent systems and control devices.

    (a)(1) Owners or operators of closed-vent systems and control 
devices used to comply with provisions of this part shall comply with 
the provisions of this section.
    (2) The owner or operator of an existing facility who cannot install 
a closed-vent system and control device to comply with the provisions of 
this subpart on the effective date that the facility becomes subject to 
the provisions of this subpart must prepare an implementation schedule 
that includes dates by which the closed-vent system and control device 
will be installed and in operation. The controls must be installed as 
soon as possible, but the implementation schedule may allow up to 30 
months after the effective date that the facility becomes subject to 
this subpart for installation and startup. All units that begin 
operation after December 21, 1990, must comply with the rules 
immediately (i.e., must have control devices installed and operating on

[[Page 302]]

startup of the affected unit); the 2-year implementation schedule does 
not apply to these units.
    (b) A control device involving vapor recovery (e.g., a condenser or 
adsorber) shall be designed and operated to recover the organic vapors 
vented to it with an efficiency of 95 weight percent or greater unless 
the total organic emission limits of Sec. 264.1032(a)(1) for all 
affected process vents can be attained at an efficiency less than 95 
weight percent.
    (c) An enclosed combustion device (e.g., a vapor incinerator, 
boiler, or process heater) shall be designed and operated to reduce the 
organic emissions vented to it by 95 weight percent or greater; to 
achieve a total organic compound concentration of 20 ppmv, expressed as 
the sum of the actual compounds, not carbon equivalents, on a dry basis 
corrected to 3 percent oxygen; or to provide a minimum residence time of 
0.50 seconds at a minimum temperature of 760  deg.C. If a boiler or 
process heater is used as the control device, then the vent stream shall 
be introduced into the flame zone of the boiler or process heater.
    (d)(1) A flare shall be designed for and operated with no visible 
emissions as determined by the methods specified in paragraph (e)(1) of 
this section, except for periods not to exceed a total of 5 minutes 
during any 2 consecutive hours.
    (2) A flare shall be operated with a flame present at all times, as 
determined by the methods specified in paragraph (f)(2)(iii) of this 
section.
    (3) A flare shall be used only if the net heating value of the gas 
being combusted is 11.2 MJ/scm (300 Btu/scf) or greater if the flare is 
steam-assisted or air-assisted; or if the net heating value of the gas

operator's control, compliance may, upon the Regional Administrator's 
approval, be determined using the average of the results of the two 
other runs.

[[Page 308]]

    (d) To show that a process vent associated with a hazardous waste 
distillation, fractionation, thin-film evaporation, solvent extraction, 
or air or steam stripping operation is not subject to the requirements 
of this subpart, the owner or operator must make an initial 
determination that the time-weighted, annual average total organic 
concentration of the waste managed by the waste management unit is less 
than 10 ppmw using one of the following two methods:
    (1) Direct measurement of the organic concentration of the waste 
using the following procedures:
    (i) The owner or operator must take a minimum of four grab samples 
of waste for each waste stream managed in the affected unit under 
process conditions expected to cause the maximum waste organic 
concentration.
    (ii) For waste generated onsite, the grab samples must be collected 
at a point before the waste is exposed to the atmosphere such as in an 
enclosed pipe or other closed system that is used to transfer the waste 
after generation to the first affected distillation, fractionation, 
thin-film evaporation, solvent extraction, or air or steam stripping 
operation. For waste generated offsite, the grab samples must be 
collected at the inlet to the first waste management unit that receives 
the waste provided the waste has been transferred to the facility in a 
closed system such as a tank truck and the waste is not diluted or mixed 
with other waste.
    (iii) Each sample shall be analyzed and the total organic 
concentration of the sample shall be computed using Method 9060 or 8260 
of SW-846 (incorporated by reference under Sec. 260.11).
    (iv) The arithmetic mean of the results of the analyses of the four 
samples shall apply for each waste stream managed in the unit in 
determining the time-weighted, annual average total organic 
concentration of the waste. The time-weighted average is to be 
calculated using the annual quantity of each waste stream processed and 
the mean organic concentration of each waste stream managed in the unit.
    (2) Using knowledge of the waste to determine that its total organic 
concentration is less than 10 ppmw. Documentation of the waste 
determination is required. Examples of documentation that shall be used 
to support a determination under this provision include production 
process information documenting that no organic compounds are used, 
information that the waste is generated by a process that is identical 
to a process at the same or another facility that has previously been 
demonstrated by direct measurement to generate a waste stream having a 
total organic content less than 10 ppmw, or prior speciation analysis 
results on the same waste stream where it can also be documented that no 
process changes have occurred since that analysis that could affect the 
waste total organic concentration.
    (e) The determination that distillation, fractionation, thin-film 
evaporation, solvent extraction, or air or steam stripping operations 
manage hazardous wastes with time-weighted, annual average total organic 
concentrations less than 10 ppmw shall be made as follows:
    (1) By the effective date that the facility becomes subject to the 
provisions of this subpart or by the date when the waste is first 
managed in a waste management unit, whichever is later, and
    (2) For continuously generated waste, annually, or
    (3) Whenever there is a change in the waste being managed or a 
change in the process that generates or treats the waste.
    (f) When an owner or operator and the Regional Administrator do not 
agree on whether a distillation, fractionation, thin-film evaporation, 
solvent extraction, or air or steam stripping operation manages a 
hazardous waste with organic concentrations of at least 10 ppmw based on 
knowledge of the waste, the procedures in Method 8260 of SW-846 
(incorporated by reference under Sec. 260.11) may be used to resolve the 
dispute.

Sec. 264.1035  Recordkeeping requirements.

    (a)(1) Each owner or operator subject to the provisions of this 
subpart shall

[[Page 309]]

comply with the recordkeeping requirements of this section.
    (2) An owner or operator of more than one hazardous waste management 
unit subject to the provisions of this subpart may comply with the 
recordkeeping requirements for these hazardous waste management units in 
one recordkeeping system if the system identifies each record by each 
hazardous waste management unit.
    (b) Owners and operators must record the following information in 
the facility operating record:
    (1) For facilities that comply with the provisions of 
Sec. 264.1033(a)(2), an implementation schedule that includes dates by 
which the closed-vent system and control device will be installed and in 
operation. The schedule must also include a rationale of why the 
installation cannot be completed at an earlier date. The implementation 
schedule must be in the facility operating record by the effective date 
that the facility becomes subject to the provisions of this subpart.
    (2) Up-to-date documentation of compliance with the process vent 
standards in Sec. 264.1032, including:
    (i) Information and data identifying all affected process vents, 
annual throughput and operating hours of each affected unit, estimated 
emission rates for each affected vent and for the overall facility 
(i.e., the total emissions for all affected vents at the facility), and 
the approximate location within the facility of each affected unit 
(e.g., identify the hazardous waste management units on a facility plot 
plan).
    (ii) Information and data supporting determinations of vent 
emissions and emission reductions achieved by add-on control devices 
based on engineering calculations or source tests. For the purpose of 
determining compliance, determinations of vent emissions and emission 
reductions must be made using operating parameter values (e.g., 
temperatures, flow rates, or vent stream organic compounds and 
concentrations) that represent the conditions that result in maximum 
organic emissions, such as when the waste management unit is operating 
at the highest load or capacity level reasonably expected to occur. If 
the owner or operator takes any action (e.g., managing a waste of 
different composition or increasing operating hours of affected waste 
management units) that would result in an increase in total organic 
emissions from affected process vents at the facility, then a new 
determination is required.
    (3) Where an owner or operator chooses to use test data to determine 
the organic removal efficiency or total organic compound concentration 
achieved by the control device, a performance test plan. The test plan 
must include:
    (i) A description of how it is determined that the planned test is 
going to be conducted when the hazardous waste management unit is 
operating at the highest load or capacity level reasonably expected to 
occur. This shall include the estimated or design flow rate and organic 
content of each vent stream and define the acceptable operating ranges 
of key process and control device parameters during the test program.
    (ii) A detailed engineering description of the closed-vent system 
and control device including:
    (A) Manufacturer's name and model number of control device.
    (B) Type of control device.
    (C) Dimensions of the control device.
    (D) Capacity.
    (E) Construction materials.
    (iii) A detailed description of sampling and monitoring procedures, 
including sampling and monitoring locations in the system, the equipment 
to be used, sampling and monitoring frequency, and planned analytical 
procedures for sample analysis.
    (4) Documentation of compliance with Sec. 264.1033 shall include the 
following information:
    (i) A list of all information references and sources used in 
preparing the documentation.
    (ii) Records, including the dates, of each compliance test required 
by Sec. 264.1033(k).

specifications, drawings, schematics, and piping and instrumentation 
diagrams based on the appropriate sections of ``APTI Course 415: Control 
of Gaseous Emissions'' (incorporated by reference as specified in

[[Page 310]]

waste determination by knowledge is required. Examples of documentation 
that shall be used to support a determination under this provision 
include production process information documenting that no organic 
compounds are used, information that the waste is generated by a process 
that is identical to a process at the same or another facility that has 
previously been demonstrated by direct measurement to have a total 
organic content less than 10 percent, or prior speciation analysis 
results on the same waste stream where it can also be documented that no 
process changes have occurred since that analysis that could affect the 
waste total organic concentration.

accordance with the conditions

[[Page 351]]

specified in Sec. 264.1080(d) of this subpart, the owner or operator 
shall record and maintain the following information:
    (1) A list of the individual organic peroxide compounds manufactured 
at the facility that meet the conditions specified in 
Sec. 264.1080(d)(1).
    (2) A description of how the hazardous waste containing the organic 
peroxide compounds identified in paragraph (i)(1) of this section are 
managed at the facility in tanks and containers. This description shall 
include:
    (i) For the tanks used at the facility to manage this hazardous 
waste, sufficient information shall be provided to describe for each 
tank: A facility identification number for the tank; the purpose and 
placement of this tank in the management train of this hazardous waste; 
and the procedures used to ultimately dispose of the hazardous waste 
managed in the tanks.
    (ii) For containers used at the facility to manage these hazardous 
wastes, sufficient information shall be provided to describe: A facility 
identification number for the container or group of containers; the 
purpose and placement of this container, or group of containers, in the 
management train of this hazardous waste; and the procedures used to 
ultimately dispose of the hazardous waste handled in the containers.
    (3) An explanation of why managing the hazardous waste containing 
the organic peroxide compounds identified in paragraph (i)(1) of this 
section in the tanks and containers as described in paragraph (i)(2) of 
this section would create an undue safety hazard if the air emission 
controls, as required under Secs. 264.1084 through 264.1087 of this 
subpart, are installed and operated on these waste management units. 
This explanation shall include the following information:
    (i) For tanks used at the facility to manage these hazardous wastes, 
sufficient information shall be provided to explain: How use of the 
required air emission controls on the tanks would affect the tank design 
features and facility operating procedures currently used to prevent an 
undue safety hazard during the management of this hazardous waste in the 
tanks; and why installation of safety devices on the required air 
emission controls, as allowed under this subpart, will not address those 
situations in which evacuation of tanks equipped with these air emission 
controls is necessary and consistent with good engineering and safety 
practices for handling organic peroxides.
    (ii) For containers used at the facility to manage these hazardous 
wastes, sufficient information shall be provided to explain: How use of 
the required air emission controls on the containers would affect the 
container design features and handling procedures currently used to 
prevent an undue safety hazard during the management of this hazardous 
waste in the containers; and why installation of safety devices on the 
required air emission controls, as allowed under this subpart, will not 
address those situations in which evacuation of containers equipped with 
these air emission controls is necessary and consistent with good 
engineering and safety practices for handling organic peroxides.

    Source: 57 FR 37265, Aug. 18, 1992, unless otherwise noted.



Sec. 264.1100  Applicability.

    The requirements of this subpart apply to owners or operators who 
store or treat hazardous waste in units designed and operated under 
Sec. 264.1101 of this subpart. These provisions will become effective on 
February 18, 1993, although owner or operator may notify the Regional 
Administrator of his intent to be bound by this subpart at an earlier 
time. The owner or operator is not subject to the definition of land 
disposal in RCRA section 3004(k) provided that the unit:
    (a) Is a completely enclosed, self-supporting structure that is 
designed and constructed of manmade materials of sufficient strength and 
thickness to support themselves, the waste contents, and any personnel 
and heavy equipment that operate within the unit, and to prevent failure 
due to pressure gradients, settlement, compression, or uplift, physical 
contact with the hazardous wastes to which they are exposed; climatic 
conditions; and the

[[Page 353]]

stresses of daily operation, including the movement of heavy equipment 
within the unit and contact of such equipment with containment walls;
    (b) Has a primary barrier that is designed to be sufficiently 
durable to withstand the movement of personnel, wastes, and handling 
equipment within the unit;
    (c) If the unit is used to manage liquids, has:
    (1) A primary barrier designed and constructed of materials to 
prevent migration of hazardous constituents into the barrier;
    (2) A liquid collection system designed and constructed of materials 
to minimize the accumulation of liquid on the primary barrier; and
    (3) A secondary containment system designed and constructed of 
materials to prevent migration of hazardous constituents into the 
barrier, with a leak detection and liquid collection system capable of 
detecting, collecting, and removing leaks of hazardous constituents at 
the earliest practicable time, unless the unit has been granted a 
variance from the secondary containment system requirements under 
Sec. 264.1101(b)(4);
    (d) Has controls sufficient to prevent fugitive dust emissions to 
meet the no visible emission standard in Sec. 264.1101(c)(1)(iv); and
    (e) Is designed and operated to ensure containment and prevent the 
tracking of materials from the unit by personnel or equipment.



Sec. 264.1101  Design and operating standards.

    (a) All containment buildings must comply with the following design 
standards:
    (1) The containment building must be completely enclosed with a 
floor, walls, and a roof to prevent exposure to the elements, (e.g., 
precipitation, wind, run-on), and to assure containment of managed 
wastes.
    (2) The floor and containment walls of the unit, including the 
secondary containment system if required under paragraph (b) of this 
section, must be designed and constructed of materials of sufficient 
strength and thickness to support themselves, the waste contents, and 
any personnel and heavy equipment that operate within the unit, and to 
prevent failure due to pressure gradients, settlement, compression, or 
uplift, physical contact with the hazardous wastes to which they are 
exposed; climatic conditions; and the stresses of daily operation, 
including the movement of heavy equipment within the unit and contact of 
such equipment with containment walls. The unit must be designed so that 
it has sufficient structural strength to prevent collapse or other 
failure. All surfaces to be in contact with hazardous wastes must be 
chemically compatible with those wastes. EPA will consider standards 
established by professional organizations generally recognized by the 
industry such as the American Concrete Institute (ACI) and the American 
Society of Testing Materials (ASTM) in judging the structural integrity 
requirements of this paragraph. If appropriate to the nature of the 
waste management operation to take place in the unit, an exception to 
the structural strength requirement may be made for light-weight doors 
and windows that meet these criteria:
    (i) They provide an effective barrier against fugitive dust 
emissions under paragraph (c)(1)(iv); and
    (ii) The unit is designed and operated in a fashion that assures 
that wastes will not actually come in contact with these openings.
    (3) Incompatible hazardous wastes or treatment reagents must not be 
placed in the unit or its secondary containment system if they could 
cause the unit or secondary containment system to leak, corrode, or 
otherwise fail.
    (4) A containment building must have a primary barrier designed to 
withstand the movement of personnel, waste, and handling equipment in 
the unit during the operating life of the unit and appropriate for the 
physical and chemical characteristics of the waste to be managed.
    (b) For a containment building used to manage hazardous wastes 
containing free liquids or treated with free liquids (the presence of 
which is determined by the paint filter test, a visual examination, or 
other appropriate means), the owner or operator must include:
    (1) A primary barrier designed and constructed of materials to 
prevent the

[[Page 354]]

migration of hazardous constituents into the barrier (e.g., a 
geomembrane covered by a concrete wear surface).
    (2) A liquid collection and removal system to minimize the 
accumulation of liquid on the primary barrier of the containment 
building:
    (i) The primary barrier must be sloped to drain liquids to the 
associated collection system; and
    (ii) Liquids and waste must be collected and removed to minimize 
hydraulic head on the containment system at the earliest practicable 
time.
    (3) A secondary containment system including a secondary barrier 
designed and constructed to prevent migration of hazardous constituents 
into the barrier, and a leak detection system that is capable of 
detecting failure of the primary barrier and collecting accumulated 
hazardous wastes and liquids at the earliest practicable time.
    (i) The requirements of the leak detection component of the 
secondary containment system are satisfied by installation of a system 
that is, at a minimum:
    (A) Constructed with a bottom slope of 1 percent or more; and
    (B) Constructed of a granular drainage material with a hydraulic 
conductivity of 1 x 10-2 cm/sec or more and a thickness of 12 
inches (30.5 cm) or more, or constructed of synthetic or geonet drainage 
materials with a transmissivity of 3 x 10-5 m\2\/sec or more.
    (ii) If treatment is to be conducted in the building, an area in 
which such treatment will be conducted must be designed to prevent the 
release of liquids, wet materials, or liquid aerosols to other portions 
of the building.
    (iii) The secondary containment system must be constructed of 
materials that are chemically resistant to the waste and liquids managed 
in the containment building and of sufficient strength and thickness to 
prevent collapse under the pressure exerted by overlaying materials and 
by any equipment used in the containment building. (Containment 
buildings can serve as secondary containment systems for tanks placed 
within the building under certain conditions. A containment building can 
serve as an external liner system for a tank, provided it meets the 
requirements of Sec. 264.193(d)(1). In addition, the containment 
building must meet the requirements of Sec. 264.193(b) and 
Secs. 264.193(c) (1) and (2) to be considered an acceptable secondary 
containment system for a tank.)
    (4) For existing units other than 90-day generator units, the 
Regional Administrator may delay the secondary containment requirement 
for up to two years, based on a demonstration by the owner or operator 
that the unit substantially meets the standards of this subpart. In 
making this demonstration, the owner or operator must:
    (i) Provide written notice to the Regional Administrator of their 
request by November 16, 1992. This notification must describe the unit 
and its operating practices with specific reference to the performance 
of existing containment systems, and specific plans for retrofitting the 
unit with secondary containment;
    (ii) Respond to any comments from the Regional Administrator on 
these plans within 30 days; and
    (iii) Fulfill the terms of the revised plans, if such plans are 
approved by the Regional Administrator.
    (c) Owners or operators of all containment buildings must:
    (1) Use controls and practices to ensure containment of the 
hazardous waste within the unit; and, at a minimum:
    (i) Maintain the primary barrier to be free of significant cracks, 
gaps, corrosion, or other deterioration that could cause hazardous waste 
to be released from the primary barrier;
    (ii) Maintain the level of the stored/treated hazardous waste within 
the containment walls of the unit so that the height of any containment 
wall is not exceeded;
    (iii) Take measures to prevent the tracking of hazardous waste out 
of the unit by personnel or by equipment used in handling the waste. An 
area must be designated to decontaminate equipment and any rinsate must 
be collected and properly managed; and
    (iv) Take measures to control fugitive dust emissions such that any 
openings (doors, windows, vents, cracks, etc.) exhibit no visible 
emissions (see 40 CFR part 60, appendix A, Method 22--Visual 
Determination of Fugitive Emissions from Material Sources and

[[Page 355]]

Smoke Emissions from Flares). In addition, all associated particulate 
collection devices (e.g., fabric filter, electrostatic precipitator) 
must be operated and maintained with sound air pollution control 
practices (see 40 CFR part 60 subpart 292 for guidance). This state of 
no visible emissions must be maintained effectively at all times during 
routine operating and maintenance conditions, including when vehicles 
and personnel are entering and exiting the unit.
    (2) Obtain certification by a qualified registered professional 
engineer that the containment building design meets the requirements of 
paragraphs (a) through (c) of this section. For units placed into 
operation prior to February 18, 1993, this certification must be placed 
in the facility's operating record (on-site files for generators who are 
not formally required to have operating records) no later than 60 days 
after the date of initial operation of the unit. After February 18, 
1993, PE certification will be required prior to operation of the unit.
    (3) Throughout the active life of the containment building, if the 
owner or operator detects a condition that could lead to or has caused a 
release of hazardous waste, must repair the condition promptly, in 
accordance with the following procedures.
    (i) Upon detection of a condition that has lead to a release of 
hazardous waste (e.g., upon detection of leakage from the primary 
barrier) the owner or operator must:
    (A) Enter a record of the discovery in the facility operating 
record;
    (B) Immediately remove the portion of the containment building 
affected by the condition from service;
    (C) Determine what steps must be taken to repair the containment 
building, remove any leakage from the secondary collection system, and 
establish a schedule for accomplishing the cleanup and repairs; and
    (D) Within 7 days after the discovery of the condition, notify the 
Regional Administrator of the condition, and within 14 working days, 
provide a written notice to the Regional Administrator with a 
description of the steps taken to repair the containment building, and 
the schedule for accomplishing the work.
    (ii) The Regional Administrator will review the information 
submitted, make a determination regarding whether the containment 
building must be removed from service completely or partially until 
repairs and cleanup are complete, and notify the owner or operator of 
the determination and the underlying rationale in writing.
    (iii) Upon completing all repairs and cleanup the owner or operator 
must notify the Regional Administrator in writing and provide a 
verification, signed by a qualified, registered professional engineer, 
that the repairs and cleanup have been completed according to the 
written plan submitted in accordance with paragraph (c)(3)(i)(D) of this 
section.
    (4) Inspect and record in the facility's operating record, at least 
once every seven days, data gathered from monitoring equipment and leak 
detection equipment as well as the containment building and the area 
immediately surrounding the containment building to detect signs of 
releases of hazardous waste.
    (d) For containment buildings that contain areas both with and 
without secondary containment, the owner or operator must:
    (1) Design and operate each area in accordance with the requirements 
enumerated in paragraphs (a) through (c) of this section;
    (2) Take measures to prevent the release of liquids or wet materials 
into areas without secondary containment; and
    (3) Maintain in the facility's operating log a written description 
of the operating procedures used to maintain the integrity of areas 
without secondary containment.
    (e) Notwithstanding any other provision of this subpart the Regional 
Administrator may waive requirements for secondary containment for a 
permitted containment building where the owner operator demonstrates 
that the only free liquids in the unit are limited amounts of dust 
suppression liquids required to meet occupational health and

[[Page 356]]

safety requirements, and where containment of managed wastes and liquids 
can be assured without a secondary containment system.



Sec. 264.1102  Closure and post-closure care.

    (a) At closure of a containment building, the owner or operator must 
remove or decontaminate all waste residues, contaminated containment 
system components (liners, etc.,) contaminated subsoils, and structures 
and equipment contaminated with waste and leachate, and manage them as 
hazardous waste unless Sec. 261.3(d) of this chapter applies. The 
closure plan, closure activities, cost estimates for closure, and 
financial responsibility for containment buildings must meet all of the 
requirements specified in subparts G and H of this part.
    (b) If, after removing or decontaminating all residues and making 
all reasonable efforts to effect removal or decontamination of 
contaminated components, subsoils, structures, and equipment as required 
in paragraph (a) of this section, the owner or operator finds that not 
all contaminated subsoils can be practicably removed or decontaminated, 
he must close the facility and perform post-closure care in accordance 
with the closure and post-closure requirements that apply to landfills 
(Sec. 264.310). In addition, for the purposes of closure, post-closure, 
and financial responsibility, such a containment building is then 
considered to be a landfill, and the owner or operator must meet all of 
the requirements for landfills specified in subparts G and H of this 
part.

Sec. 264.1200  Applicability.

    The requirements of this subpart apply to owners or operators who 
store munitions and explosive hazardous wastes, except as Sec. 264.1 
provides otherwise. (NOTE: Depending on explosive hazards, hazardous 
waste munitions and explosives may also be managed in other types of 
storage units, including containment buildings (40 CFR part 264, subpart 
DD), tanks (40 CFR part 264, subpart J), or containers (40 CFR part 264, 
subpart I); See 40 CFR 266.205 for storage of waste military munitions).



Sec. 264.1201  Design and operating standards.

    (a) Hazardous waste munitions and explosives storage units must be 
designed and operated with containment systems, controls, and 
monitoring, that:
    (1) Minimize the potential for detonation or other means of release 
of hazardous waste, hazardous constituents, hazardous decomposition 
products, or contaminated run-off, to the soil, ground water, surface 
water, and atmosphere;
    (2) Provide a primary barrier, which may be a container (including a 
shell) or tank, designed to contain the hazardous waste;
    (3) For wastes stored outdoors, provide that the waste and 
containers will not be in standing precipitation;
    (4) For liquid wastes, provide a secondary containment system that 
assures that any released liquids are contained and promptly detected 
and removed from the waste area, or vapor detection system that assures 
that any released liquids or vapors are promptly detected and an 
appropriate response taken (e.g., additional containment, such as 
overpacking, or removal from the waste area); and
    (5) Provide monitoring and inspection procedures that assure the 
controls and containment systems are working as designed and that 
releases that may adversely impact human health or the environment are 
not escaping from the unit.
    (b) Hazardous waste munitions and explosives stored under this 
subpart may be stored in one of the following:
    (1) Earth-covered magazines. Earth-covered magazines must be:
    (i) Constructed of waterproofed, reinforced concrete or structural 
steel

[[Page 357]]

arches, with steel doors that are kept closed when not being accessed;
    (ii) Designed and constructed:
    (A) To be of sufficient strength and thickness to support the weight 
of any explosives or munitions stored and any equipment used in the 
unit;
    (B) To provide working space for personnel and equipment in the 
unit; and
    (C) To withstand movement activities that occur in the unit; and
    (iii) Located and designed, with walls and earthen covers that 
direct an explosion in the unit in a safe direction, so as to minimize 
the propagation of an explosion to adjacent units and to minimize other 
effects of any explosion.
    (2) Above-ground magazines. Above-ground magazines must be located 
and designed so as to minimize the propagation of an explosion to 
adjacent units and to minimize other effects of any explosion.
    (3) Outdoor or open storage areas. Outdoor or open storage areas 
must be located and designed so as to minimize the propagation of an 
explosion to adjacent units and to minimize other effects of any 
explosion.
    (c) Hazardous waste munitions and explosives must be stored in 
accordance with a Standard Operating Procedure specifying procedures to 
ensure safety, security, and environmental protection. If these 
procedures serve the same purpose as the security and inspection 
requirements of 40 CFR 264.14, the preparedness and prevention 
procedures of 40 CFR part 264, subpart C, and the contingency plan and 
emergency procedures requirements of 40 CFR part 264, subpart D, then 
these procedures will be used to fulfill those requirements.
    (d) Hazardous waste munitions and explosives must be packaged to 
ensure safety in handling and storage.
    (e) Hazardous waste munitions and explosives must be inventoried at 
least annually.
    (f) Hazardous waste munitions and explosives and their storage units 
must be inspected and monitored as necessary to ensure explosives safety 
and to ensure that there is no migration of contaminants out of the 
unit.



Sec. 264.1202  Closure and post-closure care.

    (a) At closure of a magazine or unit which stored hazardous waste 
under this subpart, the owner or operator must remove or decontaminate 
all waste residues, contaminated containment system components, 
contaminated subsoils, and structures and equipment contaminated with 
waste, and manage them as hazardous waste unless Sec. 261.3(d) of this 
chapter applies. The closure plan, closure activities, cost estimates 
for closure, and financial responsibility for magazines or units must 
meet all of the requirements specified in subparts G and H of this part, 
except that the owner or operator may defer closure of the unit as long 
as it remains in service as a munitions or explosives magazine or 
storage unit.
    (b) If, after removing or decontaminating all residues and making 
all reasonable efforts to effect removal or decontamination of 
contaminated components, subsoils, structures, and equipment as required 
in paragraph (a) of this section, the owner or operator finds that not 
all contaminated subsoils can be practicably removed or decontaminated, 
he or she must close the facility and perform post-closure care in 
accordance with the closure and post-closure requirements that apply to 
landfills (Sec. 264.310).

                         Appendices to Part 264

           Appendix I to Part 264--Recordkeeping Instructions

    The recordkeeping provisions of Sec. 264.73 specify that an owner or 
operator must keep a written operating record at his facility. This 
appendix provides additional instructions for keeping portions of the 
operating record. See Sec. 264.73(b) for additional recordkeeping 
requirements.
    The following information must be recorded, as it becomes available, 
and maintained in the operating record until closure of the facility in 
the following manner:
    Records of each hazardous waste received, treated, stored, or 
disposed of at the facility which include the following:
    (1) A description by its common name and the EPA Hazardous Waste 
Number(s) from part 261 of this chapter which apply to the waste. The 
waste description also must include the waste's physical form, i.e., 
liquid, sludge, solid, or contained gas. If the waste

[[Page 358]]

is not listed in part 261, subpart D, of this chapter, the description 
also must include the process that produced it (for example, solid 
filter cake from production of ----, EPA Hazardous Waste Number W051).
    Each hazardous waste listed in part 261, subpart D, of this chapter, 
and each hazardous waste characteristic defined in part 261, subpart C, 
of this chapter, has a four-digit EPA Hazardous Waste Number assigned to 
it. This number must be used for recordkeeping and reporting purposes. 
Where a hazardous waste contains more than one listed hazardous waste, 
or where more than one hazardous waste characteristic applies to the 
waste, the waste description must include all applicable EPA Hazardous 
Waste Numbers.
    (2) The estimated or manifest-reported weight, or volume and 
density, where applicable, in one of the units of measure specified in 
Table 1;

 Appendix IV to Part 264--Cochran's Approximation to the Behrens-Fisher 
                            Students' t-test

    Using all the available background data (nb readings), 
calculate the background mean (Xb) and background variance 
(sb2). For the single monitoring well under 
investigation (nm reading), calculate the monitoring mean 
(Xm) and monitoring variance (sm2).
    For any set of data (X1, X2, . . ., 
Xn) the mean is calculated by:


                                               X1+X2 . . . +Xn          
                                      X=         ----------             
                                                      n                 
                                                                        

and the variance is calculated by:


                                     (X1-X)2 + (X2-X)2 . . . + (Xn-X)2  
               s2=                 ------------------------------------ 
                                                    n-1                 
                                                                        

where ``n'' denotes the number of
observations in the set of data.

    The t-test uses these data summary measures to calculate a t-
statistic (t*) and a comparison t-statistic (tc). The t* 
value is compared to the tc value and a conclusion reached as 
to whether there has been a statistically significant change in any 
indicator parameter.
    The t-statistic for all parameters except pH and similar monitoring 
parameters is:

[GRAPHIC] [TIFF OMITTED] TR26OC93.011


If the value of this t-statistic is negative then there is no 
significant difference between the monitoring data and background data. 
It should be noted that significantly small negative values may be 
indicative of a failure of the assumption made for test validity or 
errors have been made in collecting the background data.
    The t-statistic (tc), against which t* will be compared, 
necessitates finding tb and tm from standard (one-
tailed) tables where,

tb=t-tables with (nb-1) degrees of freedom, at the 
0.05 level of significance.
tm=t-tables with (nm-1) degrees of freedom, at the 
0.05 level of significance.


[[Page 360]]


    Finally, the special weightings Wb and Wm are 
defined as:


                                                      sb2                                  sm2                  
                                               WB=   ----           and             Wm=   ----                  
                                                      nb                                   nm                   
                                                                                                                

and so the comparison t-statistic is:


                                                Wbtb+Wmtm               
                                    tc=                                 
                                                  Wb+Wm                 
                                                                        

    The t-statistic (t*) is now compared with the comparison t-statistic 
(tc) using the following decision-rule:

  If t* is equal to or larger than tc, then conclude that 
there most likely has been a significant increase in this specific 
parameter.
  If t* is less than tc, then conclude that most likely there 
has not been a change in this specific parameter.

    The t-statistic for testing pH and similar monitoring parameters is 
constructed in the same manner as previously described except the 
negative sign (if any) is discarded and the caveat concerning the 
negative value is ignored. The standard (two-tailed) tables are used in 
the construction tc for pH and similar monitoring parameters.
    If t* is equal to or larger than tc, then conclude that 
there most likely has been a significant increase (if the initial t* had 
been negative, this would imply a significant decrease). If t* is less 
than tc, then conclude that there most likely has been no 
change.
    A further discussion of the test may be found in Statistical Methods 
(6th Edition, Section 4.14) by G. W. Snedecor and W. G. Cochran, or

G. D. Steel and J. H. Torrie.

   Appendix V to Part 264--Examples of Potentially Incompatible Waste

    Many hazardous wastes, when mixed with other waste or materials at a 
hazardous waste facility, can produce effects which are harmful to human 
health and the environment, such as (1) heat or pressure, (2) fire or 
explosion, (3) violent reaction, (4) toxic dusts, mists, fumes, or 
gases, or (5) flammable fumes or gases.
    Below are examples of potentially incompatible wastes, waste 
components, and materials, along with the harmful consequences which 
result from mixing materials in one group with materials in another 
group. The list is intended as a guide to owners or operators of 
treatment, storage, and disposal facilities, and to enforcement and 
permit granting officials, to indicate the need for special precautions 
when managing these potentially incompatible waste materials or 
components.
    This list is not intended to be exhaustive. An owner or operator 
must, as the regulations require, adequately analyze his wastes so that 
he can avoid creating uncontrolled substances or reactions of the type 
listed below, whether they are listed below or not.
    It is possible for potentially incompatible wastes to be mixed in a 
way that precludes a reaction (e.g., adding acid to water rather than 
water to acid) or that neutralizes them (e.g., a strong acid mixed with 
a strong base), or that controls substances produced (e.g., by 
generating flammable gases in a closed tank equipped so that ignition 
cannot occur, and burning the gases in an incinerator).
    In the lists below, the mixing of a Group A material with a Group B 
material may have the potential consequence as noted.

\2\ Common names are those widely used in government regulations, scientific publications, and commerce;        
  synonyms exist for many chemicals.                                                                            
\3\ Chemical Abstracts Service registry number. Where ``Total'' is entered, all species in the ground water that
  contain this element are included.                                                                            
\4\ CAS index names are those used in the 9th Cumulative Index.                                                 
\5\ Suggested methods refer to analytical procedure numbers used in the EPA publication, SW-846, ``Test Methods 
  for Evaluating Solid Waste'', Third Edition. Analytical details can be found in SW-846 and in documentation on
  file at the Agency. The packed column gas chromatography methods 8010, 8020, 8030, 8040, 8060, 8080, 8090,    
  8110, 8120, 8140, 8150, 8240, and 8250 were promulgated methods through Update IIB of SW-846 and, as of Update
  III, the Agency has replaced these methods with ``capillary column GC methods'', as the suggested methods.    
\6\ Practical Quantitation Limits (PQLs) are the lowest concentrations of analytes in ground waters that can be 
  reliably determined within specified limits of precision and accuracy by the indicated methods under routine  
  laboratory operating conditions. The PQLs listed are generally stated to one significant figure. CAUTION: The 
  PQL values in many cases are based only on a general estimate for the method and not on a determination for   
  individual compounds; PQLs are not a part of the regulation.                                                  
\7\ Polychlorinated biphenyls (CAS RN 1336-36-3); this category contains congener chemicals, including          
  constituents of Aroclor-1016 (CAS RN 12674-11-2), Aroclor-1221 (CAS RN 11104-28-2), Aroclor-1232 (CAS RN 11141-
  16-5), Aroclor-1242 (CAS RN 53469-21-9), Aroclor-1248 (CAS RN 12672-29-6), Aroclor-1254 (CAS RN 11097-69-1),  
  and Aroclor-1260 (CAS RN 11096-82-5). The PQL shown is an average value for PCB congeners.                    
\8\ This category contains congener chemicals, including tetrachlorodibenzo-p-dioxins (see also 2,3,7,8-TCDD),  
  pentachlorodibenzo-p-dioxins, and hexachlorodibenzo-p-dioxins. The PQL shown is an average value for PCDD     
  congeners.                                                                                                    
\9\ This category contains congener chemicals, including tetrachlorodibenzofurans, pentachlorodibenzofurans, and
  hexachlorodibenzofurans. The PQL shown is an average value for PCDF congeners.

                           Subpart A--General



Sec. 265.1  Purpose, scope, and applicability.

    (a) The purpose of this part is to establish minimum national 
standards that define the acceptable management of hazardous waste 
during the period of interim status and until certification of final 
closure or, if the facility is subject to post-closure requirements, 
until post-closure responsibilities are fulfilled.
    (b) Except as provided in Sec. 265.1080(b), the standards of this 
part, and of 40 CFR 264.552 and 40 CFR 264.553, apply to owners and 
operators of facilities that treat, store or dispose of hazardous waste 
who have fully complied with the requirements for interim status under 
section 3005(e) of RCRA and Sec. 270.10 of this chapter until either a 
permit is issued under section 3005 of RCRA or until applicable part 265 
closure and post-closure responsibilities are fulfilled, and to those 
owners and operators of facilities in existence on November 19, 1980 who 
have failed to provide timely notification as required by section 
3010(a) of RCRA and/or failed to file Part A of the permit application 
as required by 40 CFR 270.10 (e) and (g). These standards apply to all 
treatment, storage and disposal of hazardous waste at these facilities 
after the effective date of these regulations, except as specifically 
provided otherwise in this part or part 261 of this chapter.

[Comment: As stated in section 3005(a) of RCRA, after the effective date 
of regulations under that section (i.e., parts 270 and 124 of this 
chapter), the treatment, storage and disposal of hazardous waste is 
prohibited except in accordance with a permit. Section 3005(e) of RCRA 
provides for the continued operation of an existing facility that meets 
certain conditions, until final administrative disposition of the 
owner's and operator's permit application is made.]

    (c) The requirements of this part do not apply to:
    (1) A person disposing of hazardous waste by means of ocean disposal 
subject to a permit issued under the Marine Protection, Research, and 
Sanctuaries Act;

[Comment: These part 265 regulations do apply to the treatment or 
storage of hazardous waste before it is loaded onto an ocean vessel for 
incineration or disposal at sea, as provided in paragraph (b) of this 
section.]

    (2) [Reserved]
    (3) The owner or operator of a POTW which treats, stores, or 
disposes of hazardous waste;

[Comment: The owner or operator of a facility under paragraphs (c)(1) 
through (3) of this section is subject to the requirements of part 264 
of this chapter to the extent they are included in a permit by rule 
granted to such a person under part 122 of this chapter, or are required 
by Sec. 144.14 of this chapter.]

    (4) A person who treats, stores, or disposes of hazardous waste in a 
State with a RCRA hazardous waste program authorized under subpart A or 
B of part 271 of this chapter, except that the requirements of this part 
will continue to apply:
    (i) As stated in paragraph (c)(2) of this section, if the authorized 
State RCRA program does not cover disposal of hazardous waste by means 
of underground injection; or
    (ii) To a person who treats, stores, or disposes of hazardous waste 
in a State authorized under subpart A or B of part 271 of this chapter 
if the State has not been authorized to carry out the requirements and 
prohibitions applicable to the treatment, storage, or disposal of 
hazardous waste at his facility which are imposed pursuant to the 
Hazardous and Solid Waste Act Amendments of 1984. The requirements and 
prohibitions that are applicable until a

[[Page 373]]

State receives authorization to carry them out include all Federal 
program requirements identified in Sec. 271.1(j);
    (5) The owner or operator of a facility permitted, licensed, or

    (iv) In the case of an explosives or munitions emergency response, 
if a Federal, State, Tribal or local official acting within the scope of 
his or her official responsibilities, or an explosives or munitions 
emergency response specialist, determines that immediate removal of the 
material or waste is necessary to protect human health or the 
environment, that official or specialist may authorize the removal of 
the material or waste by transporters who do not have EPA identification 
numbers and without the preparation of a manifest. In the case of 
emergencies involving military munitions, the responding military 
emergency response specialist's organizational unit must retain records 
for three years identifying the dates of the response, the responsible 
persons responding, the type and description of material addressed, and 
its disposition.

FR 4514, Jan. 31, 1985; 61 FR 16315, Apr. 12, 1996]



Sec. 265.13  General waste analysis.

    (a)(1) Before an owner or operator treats, stores, or disposes of 
any hazardous wastes, or nonhazardous wastes if applicable under 
Sec. 265.113(d), he must obtain a detailed chemical and physical 
analysis of a representative sample of the wastes. At a minimum, the 
analysis must contain all the information which must be known to treat, 
store, or dispose of the waste in accordance with this part and part 268 
of this chapter.
    (2) The analysis may include data developed under part 261 of this 
chapter, and existing published or documented data on the hazardous 
waste or on waste generated from similar processes.

Comment: For example, the facility's records of analyses performed on 
the waste before the effective date of these regulations, or studies 
conducted on hazardous waste generated from processes similar to that 
which generated the waste to be managed at the facility, may be included 
in the data base required to comply with paragraph (a)(1) of this 
section. The owner or operator of an off-site facility may arrange for 
the generator of the hazardous waste to supply part of the information 
required by paragraph (a)(1) of this section, except as otherwise 
specified in 40 CFR 268.7 (b) and (c). If the generator does not supply 
the information, and the owner or operator chooses to accept a hazardous 
waste, the owner or operator is responsible for obtaining the 
information required to comply with this section.]

    (3) The analysis must be repeated as necessary to ensure that it is 
accurate and up to date. At a minimum, the analysis must be repeated:
    (i) When the owner or operator is notified, or has reason to 
believe, that the process or operation generating the hazardous wastes 
or non-hazardous wastes, if applicable, under Sec. 265.113(d) has 
changed; and
    (ii) For off-site facilities, when the results of the inspection 
required in paragraph (a)(4) of this section indicate that the hazardous 
waste received at the facility does not match the waste designated on 
the accompanying manifest or shipping paper.
    (4) The owner or operator of an off-site facility must inspect and, 
if necessary, analyze each hazardous waste movement received at the 
facility to determine whether it matches the identity of the waste 
specified on the accompanying manifest or shipping paper.
    (b) The owner or operator must develop and follow a written waste 
analysis plan which describes the procedures which he will carry out to 
comply with paragraph (a) of this section. He must keep this plan at the 
facility. At a minimum, the plan must specify:
    (1) The parameters for which each hazardous waste, or non-hazardous 
waste if applicable under Sec. 265.113(d), will be analyzed and the 
rationale for the selection of these parameters (i.e., how analysis for 
these parameters will provide sufficient information on the waste's 
properties to comply with paragraph (a) of this section);
    (2) The test methods which will be used to test for these 
parameters;
    (3) The sampling method which will be used to obtain a 
representative sample of the waste to be analyzed. A representative 
sample may be obtained using either:
    (i) One of the sampling methods described in appendix I of part 261 
of this chapter; or
    (ii) An equivalent sampling method.

[Comment: See Sec. 260.20(c) of this chapter for related discussion.]

    (4) The frequency with which the initial analysis of the waste will 
be reviewed or repeated to ensure that the analysis is accurate and up 
to date;
    (5) For off-site facilities, the waste analyses that hazardous waste 
generators have agreed to supply; and
    (6) Where applicable, the methods that will be used to meet the 
additional waste analysis requirements for specific waste management 
methods as specified in Secs. 265.200, 265.225, 265.252, 265.273, 
265.314, 265.341, 265.375, 265.402, 265.1034(d), 265.1063(d), 265.1084, 
and 268.7 of this chapter.

[[Page 376]]

    (7) For surface impoundments exempted from land disposal 
restrictions under Sec. 268.4(a) of this chapter, the procedures and 
schedule for:
    (i) The sampling of impoundment contents;
    (ii) The analysis of test data; and,
    (iii) The annual removal of residues which are not delisted under 
Sec. 260.22 of this chapter or which exhibit a characteristic of 
hazardous waste and either:
    (A) Do not meet applicable treatment standards of part 268, subpart 
D; or
    (B) Where no treatment standards have been established;
    (1) Such residues are prohibited from land disposal under 
Sec. 268.32 or RCRA section 3004(d); or
    (2) Such residues are prohibited from land disposal under 
Sec. 268.33(f).
    (8) For owners and operators seeking an exemption to the air 
emission standards of Subpart CC of this part in accordance with 
Sec. 265.1083--
    (i) If direct measurement is used for the waste determination, the 
procedures and schedules for waste sampling and analysis, and the 
results of the analysis of test data to verify the exemption.
    (ii) If knowledge of the waste is used for the waste determination, 
any information prepared by the facility owner or operator or by the 
generator of the hazardous waste, if the waste is received from off-
site, that is used as the basis for knowledge of the waste.
    (c) For off-site facilities, the waste analysis plan required in 
paragraph (b) of this section must also specify the procedures which 
will be used to inspect and, if necessary, analyze each movement of 
hazardous waste received at the facility to ensure that it matches the 
identity of the waste designated on the accompanying manifest or 
shipping paper. At a minimum, the plan must describe:
    (1) The procedures which will be used to determine the identity of 
each movement of waste managed at the facility; and
    (2) The sampling method which will be used to obtain a 
representative sample of the waste to be identified, if the 
identification method includes sampling.
    (3) The procedures that the owner or operator of an off-site 
landfill receiving containerized hazardous waste will use to determine 
whether a hazardous waste generator or treater has added a biodegradable 
sorbent to the waste in the container.

Sec. 265.14  Security.

    (a) The owner or operator must prevent the unknowing entry, and 
minimize the possibility for the unauthorized entry, of persons or 
livestock onto the active portion of his facility, unless:
    (1) Physical contact with the waste, structures, or equipment with 
the active portion of the facility will not injure unknowing or 
unauthorized persons or livestock which may enter the active portion of 
a facility, and
    (2) Disturbance of the waste or equipment, by the unknowing or 
unauthorized entry of persons or livestock onto the active portion of a 
facility, will not cause a violation of the requirements of this part.
    (b) Unless exempt under paragraphs (a)(1) and (2) of this section, a 
facility must have:
    (1) A 24-hour surveillance system (e.g., television monitoring or 
surveillance by guards of facility personnel) which continuously 
monitors and controls entry onto the active portion of the facility; or
    (2)(i) An artificial or natural barrier (e.g., a fence in good 
repair or a fence combined with a cliff), which completely surrounds the 
active portion of the facility; and
    (ii) A means to control entry, at all times, through the gates or 
other entrances to the active portion of the facility (e.g., an 
attendant, television

[[Page 377]]

monitors, locked entrance, or controlled roadway access to the 
facility).

[Comment: The requirements of paragraph (b) of this section are 
satisfied if the facility or plant within which the active portion is 
located itself has a surveillance system, or a barrier and a means to 
control entry, which complies with the requirements of paragraph (b)(1) 
or (2) of this section.]

    (c) Unless exempt under paragraphs (a)(1) and (a)(2) of this 
section, a sign with the legend, ``Danger--Unauthorized Personnel Keep 
Out,'' must be posted at each entrance to the active portion of a 
facility, and at other locations, in sufficient numbers to be seen from 
any approach to this active portion. The legend must be written in 
English and in any other language predominant in the area surrounding 
the facility (e.g., facilities in counties bordering the Canadian 
province of Quebec must post signs in French; facilities in counties 
bordering Mexico must post signs in Spanish), and must be legible from a 
distance of at least 25 feet. Existing signs with a legend other than 
``Danger--Unauthorized Personnel Keep Out'' may be used if the legend on 
the sign indicates that only authorized personnel are allowed to enter 
the active portion, and that entry onto the active portion can be 
dangerous.

[Comment: See Sec. 265.117(b) for discussion of security requirements at 
disposal facilities during the post-closure care period.]



Sec. 265.15  General inspection requirements.

    (a) The owner or operator must inspect his facility for malfunctions 
and deterioration, operator errors, and discharges which may be 
causing--or may lead to: (1) Release of hazardous waste constituents to 
the environment or (2) a threat to human health. The owner or operator 
must conduct these inspections often enough to identify problems in time 
to correct them before they harm human health or the environment.
    (b)(1) The owner or operator must develop and follow a written 
schedule for inspecting all monitoring equipment, safety and emergency 
equipment, security devices, and operating and structural equipment 
(such as dikes and sump pumps) that are important to preventing, 
detecting, or responding to environmental or human health hazards.
    (2) He must keep this schedule at the facility.
    (3) The schedule must identify the types of problems (e.g., 
malfunctions or deterioration) which are to be looked for during the 
inspection (e.g., inoperative sump pump, leaking fitting, eroding dike, 
etc.).
    (4) The frequency of inspection may vary for the items on the 
schedule. However, it should be based on the rate of deterioration of 
the equipment and the probability of an environmental or human health 
incident if the deterioration, malfunction, or any operator error goes 
undetected between inspections. Areas subject to spills, such as loading 
and unloading areas, must be inspected daily when in use. At a minimum, 
the inspection schedule must include the items and frequencies called 
for in Secs. 265.174, 265.193, 265.195, 265.226, 265.260, 265.278, 
265.304, 265.347, 265.377, 265.403, 265.1033, 265.1052, 265.1053, 
265.1058, 265.1089, and 265.1091b where applicable.
    (c) The owner or operator must remedy any deterioration or 
malfunction of equipment or structures which the inspection reveals on a 
schedule which ensures that the problem does not lead to an 
environmental or human health hazard. Where a hazard is imminent or has 
already occurred, remedial action must be taken immediately.
    (d) The owner or operator must record inspections in an inspection 
log or summary. He must keep these records for at least three years from 
the date of inspection. At a minimum, these records must include the 
date and time of the inspection, the name of the inspector, a notation 
of the observations made, and the date and nature of any repairs or 
other remedial actions.

Sec. 265.17  General requirements for ignitable, reactive, or incompatible wastes.

    (a) The owner or operator must take precautions to prevent 
accidental ignition or reaction of ignitable or reactive waste. This 
waste must be separated and protected from sources of ignition or 
reaction including but not limited to: Open flames, smoking, cutting and 
welding, hot surfaces, frictional heat, sparks (static, electrical, or 
mechanical), spontaneous ignition (e.g., from heat-producing chemical 
reactions), and radiant heat. While ignitable or reactive waste is being 
handled, the owner or operator must confine smoking and open flame to 
specially designated locations. ``No Smoking'' signs must be 
conspicuously placed wherever there is a hazard from ignitable or 
reactive waste.
    (b) Where specifically required by other sections of this part, the 
treatment, storage, or disposal of ignitable or reactive waste, and the 
mixture or commingling of incompatible wastes, or incompatible wastes 
and materials, must be conducted so that it does not:

[[Page 379]]

    (1) Generate extreme heat or pressure, fire or explosion, or violent 
reaction;
    (2) Produce uncontrolled toxic mists, fumes, dusts, or gases in 
sufficient quantities to threaten human health;
    (3) Produce uncontrolled flammable fumes or gases in sufficient 
quantities to pose a risk of fire or explosions;
    (4) Damage the structural integrity of the device or facility 
containing the waste; or
    (5) Through other like means threaten human health or the 
environment.



Sec. 265.18


  Location standards.

    The placement of any hazardous waste in a salt dome, salt bed 
formation, underground mine or cave is prohibited, except for the 
Department of Energy Waste Isolation Pilot Project in New Mexico.

[50 FR 28749, July 15, 1985]



Sec. 265.19


  Construction quality assurance program.

    (a) CQA program. (1) A construction quality assurance (CQA) program 
is required for all surface impoundment, waste pile, and landfill units 
that are required to comply with Secs. 265.221(a), 265.254, and 
265.301(a). The program must ensure that the constructed unit meets or 
exceeds all design criteria and specifications in the permit. The 
program must be developed and implemented under the direction of a CQA 
officer who is a registered professional engineer.
    (2) The CQA program must address the following physical components, 
where applicable:
    (i) Foundations;
    (ii) Dikes;
    (iii) Low-permeability soil liners;
    (iv) Geomembranes (flexible membrane liners);
    (v) Leachate collection and removal systems and leak detection 
systems; and
    (vi) Final cover systems.
    (b) Written CQA plan. Before construction begins on a unit subject 
to the CQA program under paragraph (a) of this section, the owner or 
operator must develop a written CQA plan. The plan must identify steps 
that will be used to monitor and document the quality of materials and 
the condition and manner of their installation. The CQA plan must 
include:
    (1) Identification of applicable units, and a description of how 
they will be constructed.
    (2) Identification of key personnel in the development and 
implementation of the CQA plan, and CQA officer qualifications.
    (3) A description of inspection and sampling activities for all unit 
components identified in paragraph (a)(2) of this section, including 
observations and tests that will be used before, during, and after 
construction to ensure that the construction materials and the installed 
unit components meet the design specifications. The description must 
cover: Sampling size and locations; frequency of testing; data 
evaluation procedures; acceptance and rejection criteria for 
construction materials; plans for implementing corrective measures; and 
data or other information to be recorded and retained in the operating 
record under Sec. 265.73.
    (c) Contents of program. (1) The CQA program must include 
observations, inspections, tests, and measurements sufficient to ensure:
    (i) Structural stability and integrity of all components of the unit 
identified in paragraph (a)(2) of this section;
    (ii) Proper construction of all components of the liners, leachate 
collection and removal system, leak detection system, and final cover 
system, according to permit specifications and good engineering 
practices, and proper installation of all components (e.g., pipes) 
according to design specifications;
    (iii) Conformity of all materials used with design and other 
material specifications under Secs. 264.221, 264.251, and 264.301 of 
this chapter.
    (2) The CQA program shall include test fills for compacted soil 
liners, using the same compaction methods as in the full-scale unit, to 
ensure that the liners are constructed to meet the hydraulic 
conductivity requirements of Secs. 264.221(c)(1), 264.251(c)(1), and 
264.301(c)(1) of this chapter in the field.

[[Page 380]]

Compliance with the hydraulic conductivity requirements must be verified 
by using in-situ testing on the constructed test fill. The test fill 
requirement is waived where data are sufficient to show that a 
constructed soil liner meets the hydraulic conductivity requirements of 
Secs. 264.221(c)(1), 264.254(c)(1), and 264.301(c)(1) of this chapter in 
the field.
    (d) Certification. The owner or operator of units subject to 
Sec. 265.19 must submit to the Regional Administrator by certified mail 
or hand delivery, at least 30 days prior to receiving waste, a 
certification signed by the CQA officer that the CQA plan has been 
successfully carried out and that the unit meets the requirements of 
Secs. 265.221(a), 265.254, or 265.301(a). The owner or operator may 
receive waste in the unit after 30 days from the Regional 
Administrator's receipt of the CQA certification unless the Regional 
Administrator determines in writing that the construction is not 
acceptable, or extends the review period for a maximum of 30 more days, 
or seeks additional information from the owner or operator during this 
period. Documentation supporting the CQA officer's certification must be 
furnished to the Regional Administrator upon request.

Sec. 265.55  Emergency coordinator.

    At all times, there must be at least one employee either on the 
facility premises or on call (i.e., available to respond to an emergency 
by reaching the facility within a short period of time) with the 
responsibility for coordinating all emergency response measures. This 
emergency coordinator must be thoroughly familiar with all aspects of 
the facility's contingency plan, all operations and activities at the 
facility, the location and characteristics of waste handled, the 
location of all records within the facility, and the facility layout. In 
addition, this person must have the authority to commit the resources 
needed to carry out the contingency plan.

[Comment: The emergency coordinator's responsibilities are more fully 
spelled out in Sec. 265.56. Applicable responsibilities for the 
emergency coordinator vary, depending on factors such as type and 
variety of waste(s) handled by the facility, and type and complexity of 
the facility.]



Sec. 265.56  Emergency procedures.

    (a) Whenever there is an imminent or actual emergency situation, the 
emergency coordinator (or his designee when the emergency coordinator is 
on call) must immediately:
    (1) Activate internal facility alarms or communication systems, 
where applicable, to notify all facility personnel; and
    (2) Notify appropriate State or local agencies with designated 
response roles if their help is needed.
    (b) Whenever there is a release, fire, or explosion, the emergency 
coordinator must immediately identify the character, exact source, 
amount, and a

[[Page 383]]

real extent of any released materials. He may do this by observation or 
review of facility records or manifests and, if necessary, by chemical 
analysis.
    (c) Concurrently, the emergency coordinator must assess possible 
hazards to human health or the environment that may result from the 
release, fire, or explosion. This assessment must consider both direct 
and indirect effects of the release, fire, or explosion (e.g., the 
effects of any toxic, irritating, or asphyxiating gases that are 
generated, or the effects of any hazardous surface water run-offs from 
water or chemical agents used to control fire and heat-induced 
explosions).
    (d) If the emergency coordinator determines that the facility has 
had a release, fire, or explosion which could threaten human health, or 
the environment, outside the facility, he must report his findings as 
follows:
    (1) If his assessment indicates that evacuation of local areas may 
be advisable, he must immediately notify appropriate local authorities. 
He must be available to help appropriate officials decide whether local 
areas should be evacuated; and
    (2) He must immediately notify either the government official 
designated as the on-scene coordinator for that geographical area (in 
the applicable regional contingency plan under part 1510 of this title), 
or the National Response Center (using their 24-hour toll free number 
800/424-8802). The report must include:
    (i) Name and telephone number of reporter;
    (ii) Name and address of facility;
    (iii) Time and type of incident (e.g., release, fire);
    (iv) Name and quantity of material(s) involved, to the extent known;
    (v) The extent of injuries, if any; and
    (vi) The possible hazards to human health, or the environment, 
outside the facility.
    (e) During an emergency, the emergency coordinator must take all 
reasonable measures necessary to ensure that fires, explosions, and 
releases do not occur, recur, or spread to other hazardous waste at the 
facility. These measures must include, where applicable, stopping 
processes and operations, collecting and containing released waste, and 
removing or isolating containers.
    (f) If the facility stops operations in response to a fire, 
explosion or release, the emergency coordinator must monitor for leaks, 
pressure buildup, gas generation, or ruptures in valves, pipes, or other 
equipment, wherever this is appropriate.
    (g) Immediately after an emergency, the emergency coordinator must 
provide for treating, storing, or disposing of recovered waste, 
contaminated soil or surface water, or any other material that results 
from a release, fire, or explosion at the facility.

[Comment: Unless the owner or operator can demonstrate, in accordance 
with Sec. 261.3(c) or (d) of this chapter, that the recovered material 
is not a hazardous waste, the owner or operator becomes a generator of 
hazardous waste and must manage it in accordance with all applicable 
requirements of parts 262, 263, and 265 of this chapter.]

    (h) The emergency coordinator must ensure that, in the affected 
area(s) of the facility:
    (1) No waste that may be incompatible with the released material is 
treated, stored, or disposed of until cleanup procedures are completed; 
and
    (2) All emergency equipment listed in the contingency plan is 
cleaned and fit for its intended use before operations are resumed.
    (i) The owner or operator must notify the Regional Administrator, 
and appropriate State and local authorities, that the facility is in 
compliance with paragraph (h) of this section before operations are 
resumed in the affected area(s) of the facility.
    (j) The owner or operator must note in the operating record the 
time, date, and details of any incident that requires implementing the 
contingency plan. Within 15 days after the incident, he must submit a 
written report on the incident to the Regional Administrator. The report 
must include:
    (1) Name, address, and telephone number of the owner or operator;
    (2) Name, address, and telephone number of the facility;
    (3) Date, time, and type of incident (e.g., fire, explosion);
    (4) Name and quantity of material(s) involved;
    (5) The extent of injuries, if any;

[[Page 384]]

    (6) An assessment of actual or potential hazards to human health or 
the environment, where this is applicable; and
    (7) Estimated quantity and disposition of recovered material that 
resulted from the incident.

        Subpart E--Manifest System, Recordkeeping, and Reporting



Sec. 265.70  Applicability.

    The regulations in this subpart apply to owners and operators of 
both on-site and off-site facilities, except as Sec. 265.1 provides 
otherwise. Sections 265.71, 265.72, and 265.76 do not apply to owners 
and operators of on-site facilities that do not receive any hazardous 
waste from off-site sources, and to owners and operators of off-site 
facilities with respect to waste military munitions exempted from 
manifest requirements under Sec. 266.203(a) of this chapter.

[62 FR 6653, Feb. 12, 1997]

    Effective Date Note: At 62 FR 6653, Feb. 12, 1997, Sec. 265.70 was 
revised, effective Aug. 12, 1997. For the convenience of the user, the 
superseded text is set forth as follows:
Sec. 265.70  Applicability.
    The regulations in this subpart apply to owners and operators of 
both on-site and off-site facilities, except as Sec. 265.1 provides 
otherwise. Sections 265.71, 265.72, and 265.76 do not apply to owners 
and operators of on-site facilities that do not receive any hazardous 
waste from off-site sources.



Sec. 265.71  Use of manifest system.

    (a) If a facility receives hazardous waste accompanied by a 
manifest, the owner or operator, or his agent, must:
    (1) Sign and date each copy of the manifest to certify that the 
hazardous waste covered by the manifest was received;
    (2) Note any significant discrepancies in the manifest (as defined 
in Sec. 265.72(a)) on each copy of the manifest;

[Comment: The Agency does not intend that the owner or operator of a 
facility whose procedures under Sec. 265.13(c) include waste analysis 
must perform that analysis before signing the manifest and giving it to 
the transporter. Section 265.72(b), however, requires reporting an 
unreconciled discrepancy discovered during later analysis.]

    (3) Immediately give the transporter at least one copy of the signed 
manifest;
    (4) Within 30 days after the delivery, send a copy of the manifest 
to the generator; and
    (5) Retain at the facility a copy of each manifest for at least 
three years from the date of delivery.
    (b) If a facility receives, from a rail or water (bulk shipment) 
transporter, hazardous waste which is accompanied by a shipping paper 
containing all the information required on the manifest (excluding the 
EPA identification numbers, generator's certification, and signatures), 
the owner or operator, or his agent, must:
    (1) Sign and date each copy of the manifest or shipping paper (if 
the manifest has not been received) to certify that the hazardous waste 
covered by the manifest or shipping paper was received;
    (2) Note any significant discrepancies (as defined in 
Sec. 265.72(a)) in the manifest or shipping paper (if the manifest has 
not been received) on each copy of the manifest or shipping paper;

[Comment: The Agency does not intend that the owner or operator of a 
facility whose procedures under Sec. 265.13(c) include waste analysis 
must perform that analysis before signing the shipping paper and giving 
it to the transporter. Section 265.72(b), however, requires reporting an 
unreconciled discrepancy discovered during later analysis.]

    (3) Immediately give the rail or water (bulk shipment) transporter 
at least one copy of the manifest or shipping paper (if the manifest has 
not been received);
    (4) Within 30 days after the delivery, send a copy of the signed and 
dated manifest to the generator; however, if the manifest has not been 
received within 30 days after delivery, the owner or operator, or his 
agent, must send a

[[Page 385]]

copy of the shipping paper signed and dated to the generator; and

[Comment: Section 262.23(c) of this chapter requires the generator to 
send three copies of the manifest to the facility when hazardous waste 
is sent by rail or water (bulk shipment).]

    (5) Retain at the facility a copy of the manifest and shipping paper 
(if signed in lieu of the manifest at the time of delivery) for at least 
three years from the date of delivery.
    (c) Whenever a shipment of hazardous waste is initiated from a 
facility, the owner or operator of that facility must comply with the 
requirements of part 262 of this chapter.

[Comment: The provisions of Sec. 262.34 are applicable to the on-site 
accumulation of hazardous wastes by generators. Therefore, the 
provisions of Sec. 262.34 only apply to owners or operators who are 
shipping hazardous waste which they generated at that facility.]
    (d) Within three working days of the receipt of a shipment subject 
to 40 CFR part 262, subpart H, the owner or operator of facility must 
provide a copy of the tracking document bearing all required signatures 
to the notifier, to the Office of Enforcement and Compliance Assurance, 
Office of Compliance, Enforcement Planning, Targeting and Data Division 
(2222A), Environmental Protection Agency, 401 M St., SW., Washington, DC 
20460, and to competent authorities of all other concerned countries. 
The original copy of the tracking document must be maintained at the 
facility for at least three years from the date of signature.

[45 FR 33232, May 19, 1980, as amended at 45 FR 86970, 86974, Dec. 31, 
1980; 50 FR 4514, Jan. 31, 1985; 61 FR 16315, Apr. 12, 1996]



Sec. 265.72  Manifest discrepancies.

    (a) Manifest discrepancies are differences between the quantity or 
type of hazardous waste designated on the manifest or shipping paper, 
and the quantity or type of hazardous waste a facility actually 
receives. Significant discrepancies in quantity are: (1) For bulk waste, 
variations greater than 10 percent in weight, and (2) for batch waste, 
any variation in piece count, such as a discrepancy of one drum in a 
truckload. Significant discrepancies in type are obvious differences 
which can be discovered by inspection or waste analysis, such as waste 
solvent substituted for waste acid, or toxic constituents not reported 
on the manifest or shipping paper.
    (b) Upon discovering a significant discrepancy, the owner or 
operator must attempt to reconcile the discrepancy with the waste 
generator or transporter (e.g., with telephone conversations). If the 
discrepancy is not resolved within 15 days after receiving the waste, 
the owner or operator must immediately submit to the Regional 
Administrator a letter describing the discrepancy and attempts to 
reconcile it, and a copy of the manifest or shipping paper at issue.

[45 FR 33232, May 19, 1980, as amended at 50 FR 4514, Jan. 31, 1985]



Sec. 265.73  Operating record.

    (a) The owner or operator must keep a written operating record at 
his facility.
    (b) The following information must be recorded, as it becomes 
available, and maintained in the operating record until closure of the 
facility:
    (1) A description and the quantity of each hazardous waste received, 
and the method(s) and date(s) of its treatment, storage, or disposal at 
the facility as required by appendix I;

FR 4514, Jan. 31, 1985; 51 FR 28556, Aug. 8, 1986]



Sec. 265.76  Unmanifested waste report.

    If a facility accepts for treatment, storage, or disposal any 
hazardous waste from an off-site source without an accompanying 
manifest, or without an accompanying shipping paper as described in 
Sec. 263.20(e)(2) of this chapter, and if the waste is not excluded from 
the manifest requirement by Sec. 261.5 of this chapter, then the owner 
or operator must prepare and submit a single copy of a report to the 
Regional Administrator within fifteen days after receiving the waste. 
The unmanifested waste report must be submitted on EPA form 8700-13B. 
Such report must be designated `Unmanifested Waste Report' and include 
the following information:
    (a) The EPA identification number, name, and address of the 
facility;
    (b) The date the facility received the waste;
    (c) The EPA identification number, name, and address of the 
generator and the transporter, if available;
    (d) A description and the quantity of each unmanifested hazardous 
waste the facility received;
    (e) The method of treatment, storage, or disposal for each hazardous 
waste;
    (f) The certification signed by the owner or operator of the 
facility or his authorized representative; and
    (g) A brief explanation of why the waste was unmanifested, if known.

[Comment: Small quantities of hazardous waste are excluded from 
regulation under this part and do not require a manifest. Where a 
facility receives unmanifested hazardous wastes, the Agency suggests 
that the owner or operator obtain from each generator a certification 
that the waste qualifies for exclusion. Otherwise, the Agency suggests 
that the owner or operator file an unmanifested waste report for the 
hazardous waste movement.]

Sec. 265.77  Additional reports.

    In addition to submitting the biennial report and unmanifested waste 
reports described in Secs. 265.75 and 265.76, the owner or operator must 
also report to the Regional Administrator:
    (a) Releases, fires, and explosions as specified in Sec. 265.56(j);
    (b) Ground-water contamination and monitoring data as specified in 
Secs. 265.93 and 265.94; and

                   Subpart F--Ground-Water Monitoring



Sec. 265.90  Applicability.

    (a) Within one year after the effective date of these regulations, 
the

[[Page 388]]

owner or operator of a surface impoundment, landfill, or land treatment 
facility which is used to manage hazardous waste must implement a 
ground-water monitoring program capable of determining the facility's 
impact on the quality of ground water in the uppermost aquifer 
underlying the facility, except as Sec. 265.1 and paragraph (c) of this 
section provide otherwise.
    (b) Except as paragraphs (c) and (d) of this section provide 
otherwise, the owner or operator must install, operate, and maintain a 
ground-water monitoring system which meets the requirements of 
Sec. 265.91, and must comply with Secs. 265.92 through 265.94. This 
ground-water monitoring program must be carried out during the active 
life of the facility, and for disposal facilities, during the post-
closure care period as well.
    (c) All or part of the ground-water monitoring requirements of this 
subpart may be waived if the owner or operator can demonstrate that 
there is a low potential for migration of hazardous waste or hazardous 
waste constituents from the facility via the uppermost aquifer to water 
supply wells (domestic, industrial, or agricultural) or to surface 
water. This demonstration must be in writing, and must be kept at the 
facility. This demonstration must be certified by a qualified geologist 
or geotechnical engineer and must establish the following:
    (1) The potential for migration of hazardous waste or hazardous 
waste constituents from the facility to the uppermost aquifer, by an 
evaluation of:
    (i) A water balance of precipitation, evapotranspiration, runoff, 
and infiltration; and
    (ii) Unsaturated zone characteristics (i.e., geologic materials, 
physical properties, and depth to ground water); and
    (2) The potential for hazardous waste or hazardous waste 
constituents which enter the uppermost aquifer to migrate to a water 
supply well or surface water, by an evaluation of:
    (i) Saturated zone characteristics (i.e., geologic materials, 
physical properties, and rate of ground-water flow); and
    (ii) The proximity of the facility to water supply wells or surface 
water.
    (d) If an owner or operator assumes (or knows) that ground-water 
monitoring of indicator parameters in accordance with Secs. 265.91 and 
265.92 would show statistically significant increases (or decreases in 
the case of pH) when evaluated under Sec. 265.93(b), he may, install, 
operate, and maintain an alternate ground-water monitoring system (other 
than the one described in Secs. 265.91 and 265.92). If the owner or 
operator decides to use an alternate ground-water monitoring system he 
must:
    (1) Within one year after the effective date of these regulations, 
submit to the Regional Administrator a specific plan, certified by a 
qualified geologist or geotechnical engineer, which satisfies the 
requirements of Sec. 265.93(d)(3), for an alternate ground-water 
monitoring system;
    (2) Not later than one year after the effective date of these 
regulations, initiate the determinations specified in Sec. 265.93(d)(4);
    (3) Prepare and submit a written report in accordance with 
Sec. 265.93(d)(5);
    (4) Continue to make the determinations specified in 
Sec. 265.93(d)(4) on a quarterly basis until final closure of the 
facility; and
    (5) Comply with the recordkeeping and reporting requirements in 
Sec. 265.94(b).
    (e) The ground-water monitoring requirements of this subpart may be 
waived with respect to any surface impoundment that (1) Is used to 
neutralize wastes which are hazardous solely because they exhibit the 
corrosivity characteristic under Sec. 261.22 of this chapter or are 
listed as hazardous wastes in subpart D of part 261 of this chapter only 
for this reason, and (2) contains no other hazardous wastes, if the 
owner or operator can demonstrate that there is no potential for 
migration of hazardous wastes from the impoundment. The demonstration 
must establish, based upon consideration of the characteristics of the 
wastes and the impoundment, that the corrosive wastes will be 
neutralized to the extent that they no longer meet the corrosivity 
characteristic before they can migrate out of the impoundment. The 
demonstration must be in writing

[[Page 389]]

and must be certified by a qualified professional.

FR 4514, Jan. 31, 1985]



Sec. 265.91  Ground-water monitoring system.

    (a) A ground-water monitoring system must be capable of yielding 
ground-water samples for analysis and must consist of:
    (1) Monitoring wells (at least one) installed hydraulically 
upgradient (i.e., in the direction of increasing static head) from the 
limit of the waste management area. Their number, locations, and depths 
must be sufficient to yield ground-water samples that are:
    (i) Representative of background ground-water quality in the 
uppermost aquifer near the facility; and
    (ii) Not affected by the facility; and
    (2) Monitoring wells (at least three) installed hydraulically 
downgradient (i.e., in the direction of decreasing static head) at the 
limit of the waste management area. Their number, locations, and depths 
must ensure that they immediately detect any statistically significant 
amounts of hazardous waste or hazardous waste constituents that migrate 
from the waste management area to the uppermost aquifer.
    (3) The facility owner or operator may demonstrate that an alternate 
hydraulically downgradient monitoring well location will meet the 
criteria outlined below. The demonstration must be in writing and kept 
at the facility. The demonstration must be certified by a qualified 
ground-water scientist and establish that:
    (i) An existing physical obstacle prevents monitoring well 
installation at the hydraulically downgradient limit of the waste 
management area; and
    (ii) The selected alternate downgradient location is as close to the 
limit of the waste management area as practical; and
    (iii) The location ensures detection that, given the alternate 
location, is as early as possible of any statistically significant 
amounts of hazardous waste or hazardous waste constituents that migrate 
from the waste management area to the uppermost aquifer.
    (iv) Lateral expansion, new, or replacement units are not eligible 
for an alternate downgradient location under this paragraph.
    (b) Separate monitoring systems for each waste management component 
of a facility are not required provided that provisions for sampling 
upgradient and downgradient water quality will detect any discharge from 
the waste management area.
    (1) In the case of a facility consisting of only one surface 
impoundment, landfill, or land treatment area, the waste management area 
is described by the waste boundary (perimeter).
    (2) In the case of a facility consisting of more than one surface 
impoundment, landfill, or land treatment area, the waste management area 
is described by an imaginary boundary line which circumscribes the 
several waste management components.
    (c) All monitoring wells must be cased in a manner that maintains 
the integrity of the monitoring well bore hole. This casing must be 
screened or perforated, and packed with gravel or sand where necessary, 
to enable sample collection at depths where appropriate aquifer flow 
zones exist. The annular space (i.e., the space between the bore hole 
and well casing) above the sampling depth must be sealed with a suitable 
material (e.g., cement grout or bentonite slurry) to prevent 
contamination of samples and the ground water.

FR 66369, Dec. 23, 1991]



Sec. 265.92  Sampling and analysis.

    (a) The owner or operator must obtain and analyze samples from the 
installed ground-water monitoring system. The owner or operator must 
develop and follow a ground-water sampling and analysis plan. He must 
keep this plan at the facility. The plan must include procedures and 
techniques for:
    (1) Sample collection;
    (2) Sample preservation and shipment;
    (3) Analytical procedures; and

[[Page 390]]

    (4) Chain of custody control.

[Comment: See ``Procedures Manual For Ground-water Monitoring At Solid 
Waste Disposal Facilities,'' EPA-530/SW-611, August 1977 and ``Methods 
for Chemical Analysis of Water and Wastes,'' EPA-600/4-79-020, March 
1979 for discussions of sampling and analysis procedures.]

    (b) The owner or operator must determine the concentration or value 
of the following parameters in ground-water samples in accordance with 
paragraphs (c) and (d) of this section:
    (1) Parameters characterizing the suitability of the ground water as 
a drinking water supply, as specified in appendix III.
    (2) Parameters establishing ground-water quality:
    (i) Chloride
    (ii) Iron
    (iii) Manganese
    (iv) Phenols
    (v) Sodium
    (vi) Sulfate

[Comment: These parameters are to be used as a basis for comparison in 
the event a ground-water quality assessment is required under 
Sec. 265.93(d).]

    (3) Parameters used as indicators of ground-water contamination:
    (i) pH
    (ii) Specific Conductance
    (iii) Total Organic Carbon
    (iv) Total Organic Halogen
    (c)(1) For all monitoring wells, the owner or operator must 
establish initial background concentrations or values of all parameters 
specified in paragraph (b) of this section. He must do this quarterly 
for one year.
    (2) For each of the indicator parameters specified in paragraph 
(b)(3) of this section, at least four replicate measurements must be 
obtained for each sample and the initial background arithmetic mean and 
variance must be determined by pooling the replicate measurements for 
the respective parameter concentrations or values in samples obtained 
from upgradient wells during the first year.
    (d) After the first year, all monitoring wells must be sampled and 
the samples analyzed with the following frequencies:
    (1) Samples collected to establish ground-water quality must be 
obtained and analyzed for the parameters specified in paragraph (b)(2) 
of this section at least annually.
    (2) Samples collected to indicate ground-water contamination must be 
obtained and analyzed for the parameters specified in paragraph (b)(3) 
of this section at least semi-annually.
    (e) Elevation of the ground-water surface at each monitoring well 
must be determined each time a sample is obtained.

[45 FR 33232, May 19, 1980, as amended at 50 FR 4514, Jan. 31, 1985]



Sec. 265.93  Preparation, evaluation, and response.

    (a) Within one year after the effective date of these regulations, 
the owner or operator must prepare an outline of a ground-water quality 
assessment program. The outline must describe a more comprehensive 
ground-water monitoring program (than that described in Secs. 265.91 and 
265.92) capable of determining:
    (1) Whether hazardous waste or hazardous waste constituents have 
entered the ground water;
    (2) The rate and extent of migration of hazardous waste or hazardous 
waste constituents in the ground water; and
    (3) The concentrations of hazardous waste or hazardous waste 
constituents in the ground water.
    (b) For each indicator parameter specified in Sec. 265.92(b)(3), the 
owner or operator must calculate the arithmetic mean and variance, based 
on at least four replicate measurements on each sample, for each well 
monitored in accordance with Sec. 265.92(d)(2), and compare these 
results with its initial background arithmetic mean. The comparison must 
consider individually each of the wells in the monitoring system, and 
must use the Student's t-test at the 0.01 level of significance (see 
appendix IV) to determine statistically significant increases (and 
decreases, in the case of pH) over initial background.
    (c)(1) If the comparisons for the upgradient wells made under 
paragraph (b) of this section show a significant increase (or pH 
decrease), the owner or operator must submit this information in 
accordance with Sec. 265.94(a)(2)(ii).

[[Page 391]]

    (2) If the comparisons for downgradient wells made under paragraph 
(b) of this section show a significant increase (or pH decrease), the 
owner or operator must then immediately obtain additional ground-water 
samples from those downgradient wells where a significant difference was 
detected, split the samples in two, and obtain analyses of all 
additional samples to determine whether the significant difference was a 
result of laboratory error.
    (d)(1) If the analyses performed under paragraph (c)(2) of this 
section confirm the significant increase (or pH decrease), the owner or 
operator must provide written notice to the Regional Administrator--
within seven days of the date of such confirmation--that the facility 
may be affecting ground-water quality.
    (2) Within 15 days after the notification under paragraph (d)(1) of 
this section, the owner or operator must develop and submit to the 
Regional Administrator a specific plan, based on the outline required 
under paragraph (a) of this section and certified by a qualified 
geologist or geotechnical engineer, for a ground-water quality 
assessment program at the facility.
     (3) The plan to be submitted under Sec. 265.90(d)(1) or paragraph 
(d)(2) of this section must specify:
    (i) The number, location, and depth of wells;
    (ii) Sampling and analytical methods for those hazardous wastes or 
hazardous waste constituents in the facility;
    (iii) Evaluation procedures, including any use of previously-
gathered ground-water quality information; and
    (iv) A schedule of implementation.
    (4) The owner or operator must implement the ground-water quality 
assessment plan which satisfies the requirements of paragraph (d)(3) of 
this section, and, at a minimum, determine:
    (i) The rate and extent of migration of the hazardous waste or 
hazardous waste constituents in the ground water; and
    (ii) The concentrations of the hazardous waste or hazardous waste 
constituents in the ground water.
    (5) The owner or operator must make his first determination under 
paragraph (d)(4) of this section as soon as technically feasible, and, 
within 15 days after that determination, submit to the Regional 
Administrator a written report containing an assessment of the ground-
water quality.
    (6) If the owner or operator determines, based on the results of the 
first determination under paragraph (d)(4) of this section, that no 
hazardous waste or hazardous waste constituents from the facility have 
entered the ground water, then he may reinstate the indicator evaluation 
program described in Sec. 265.92 and paragraph (b) of this section. If 
the owner or operator reinstates the indicator evaluation program, he 
must so notify the Regional Administrator in the report submitted under 
paragraph (d)(5) of this section.
    (7) If the owner or operator determines, based on the first 
determination under paragraph (d)(4) of this section, that hazardous 
waste or hazardous waste constituents from the facility have entered the 
ground water, then he:
    (i) Must continue to make the determinations required under 
paragraph (d)(4) of this section on a quarterly basis until final 
closure of the facility, if the ground-water quality assessment plan was 
implemented prior to final closure of the facility; or
    (ii) May cease to make the determinations required under paragraph 
(d)(4) of this section, if the ground-water quality assessment plan was 
implemented during the post-closure care period.
    (e) Notwithstanding any other provision of this subpart, any ground-
water quality assessment to satisfy the requirements of 
Sec. 265.93(d)(4) which is initiated prior to final closure of the 
facility must be completed and reported in accordance with 
Sec. 265.93(d)(5).
    (f) Unless the ground water is monitored to satisfy the requirements 
of Sec. 265.93(d)(4), at least annually the owner or operator must 
evaluate the data on ground-water surface elevations obtained under 
Sec. 265.92(e) to determine whether the requirements under 
Sec. 265.91(a) for locating the monitoring wells continues to be 
satisfied. If the evaluation shows that Sec. 265.91(a) is no longer 
satisfied, the owner or operator must immediately modify the

[[Page 392]]

number, location, or depth of the monitoring wells to bring the ground-
water monitoring system into compliance with this requirement.

[45 FR 33232, May 19, 1980, as amended at 50 FR 4514, Jan. 31, 1985]



Sec. 265.94  Recordkeeping and reporting.

    (a) Unless the ground water is monitored to satisfy the requirements 
of Sec. 265.93(d)(4), the owner or operator must:
    (1) Keep records of the analyses required in Sec. 265.92(c) and (d), 
the associated ground-water surface elevations required in 
Sec. 265.92(e), and the evaluations required in Sec. 265.93(b) 
throughout the active life of the facility, and, for disposal 
facilities, throughout the post-closure care period as well; and
    (2) Report the following ground-water monitoring information to the 
Regional Administrator:
    (i) During the first year when initial background concentrations are 
being established for the facility: concentrations or values of the 
parameters listed in Sec. 265.92(b)(1) for each ground-water monitoring 
well within 15 days after completing each quarterly analysis. The owner

Sec. 265.112  Closure plan; amendment of plan.

    (a) Written plan. By May 19, 1981, or by six months after the 
effective date of the rule that first subjects a facility to provisions 
of this section, the owner or operator of a hazardous waste management 
facility must have a written closure plan. Until final closure is 
completed and certified in accordance with Sec. 265.115, a copy of the 
most current plan must be furnished to the Regional Administrator upon 
request, including request by mail. In addition, for facilities without 
approved plans, it must also be provided during site inspections, on the 
day of inspection, to any officer, employee, or representative of the 
Agency who is duly designated by the Administrator.
    (b) Content of plan. The plan must identify steps necessary to 
perform partial and/or final closure of the facility at any point during 
its active life. The closure plan must include, at least:
    (1) A description of how each hazardous waste management unit at the 
facility will be closed in accordance with Sec. 265.111; and
    (2) A description of how final closure of the facility will be 
conducted in accordance with Sec. 265.111. The description must identify 
the maximum extent of the operation which will be unclosed during the 
active life of the facility; and
    (3) An estimate of the maximum inventory of hazardous wastes ever 
on-site over the active life of the facility and a detailed description 
of the methods to be used during partial and final closure, including, 
but not limited to methods for removing, transporting, treating, storing 
or disposing of all hazardous waste, identification of and the type(s) 
of off-site hazardous waste management unit(s) to be used, if 
applicable; and
    (4) A detailed description of the steps needed to remove or 
decontaminate all hazardous waste residues and contaminated containment 
system components, equipment, structures, and soils during partial and 
final closure including, but not limited to, procedures for cleaning 
equipment and removing contaminated soils, methods for sampling and 
testing surrounding soils, and criteria for determining the extent of 
decontamination necessary to satisfy the closure performance standard; 
and
    (5) A detailed description of other activities necessary during the 
partial and final closure period to ensure that all partial closures and 
final closure satisfy the closure performance standards, including, but 
not limited to, ground-water monitoring, leachate collection, and run-on 
and run-off control; and
    (6) A schedule for closure of each hazardous waste management unit 
and for final closure of the facility. The schedule must include, at a 
minimum, the total time required to close each hazardous waste 
management unit and the time required for intervening closure activities 
which will allow tracking of the progress of partial and final closure. 
(For example, in the case of a landfill unit, estimates of the time 
required to treat or dispose of all hazardous waste inventory and of the 
time required to place a final cover must be included.); and
    (7) An estimate of the expected year of final closure for facilities 
that use trust funds to demonstrate financial assurance under 
Sec. 265.143 or Sec. 265.145 and whose remaining operating life is less 
than twenty years, and for facilities without approved closure plans.
    (c) Amendment of plan. The owner or operator may amend the closure 
plan at any time prior to the notification of

[[Page 394]]

partial or final closure of the facility. An owner or operator with an 
approved closure plan must submit a written request to the Regional 
Administrator to authorize a change to the approved closure plan. The 
written request must include a copy of the amended closure plan for 
approval by the Regional Administrator.
    (1) The owner or operator must amend the closure plan whenever:
    (i) Changes in operating plans or facility design affect the closure 
plan, or
    (ii) There is a change in the expected year of closure, if 
applicable, or
    (iii) In conducting partial or final closure activities, unexpected 
events require a modification of the closure plan.
    (2) The owner or operator must amend the closure plan at least 60 
days prior to the proposed change in facility design or operation, or no 
later than 60 days after an unexpected event has occurred which has 
affected the closure plan. If an unexpected event occurs during the 
partial or final closure period, the owner or operator must amend the 
closure plan no later than 30 days after the unexpected event. These 
provisions also apply to owners or operators of surface impoundments and 
waste piles who intended to remove all hazardous wastes at closure, but 
are required to close as landfills in accordance with Sec. 265.310.
    (3) An owner or operator with an approved closure plan must submit 
the modified plan to the Regional Administrator at least 60 days prior 
to the proposed change in facility design or operation, or no more than 
60 days after an unexpected event has occurred which has affected the 
closure plan. If an unexpected event has occurred during the partial or 
final closure period, the owner or operator must submit the modified 
plan no more than 30 days after the unexpected event. These provisions 
also apply to owners or operators of surface impoundments and waste 
piles who intended to remove all hazardous wastes at closure but are 
required to close as landfills in accordance with Sec. 265.310. If the 
amendment to the plan is a Class 2 or 3 modification according to the 
criteria in Sec. 270.42, the modification to the plan will be approved 
according to the procedures in Sec. 265.112(d)(4).
    (4) The Regional Administrator may request modifications to the plan 
under the conditions described in paragraph (c)(1) of this section. An 
owner or operator with an approved closure plan must submit the modified 
plan within 60 days of the request from the Regional Administrator, or 
within 30 days if the unexpected event occurs during partial or final 
closure. If the amendment is considered a Class 2 or 3 modification 
according to the criteria in Sec. 270.42, the modification to the plan 
will be approved in accordance with the procedures in 
Sec. 265.112(d)(4).
    (d) Notification of partial closure and final closure. (1) The owner 
or operator must submit the closure plan to the Regional Administrator 
at least 180 days prior to the date on which he expects to begin closure 
of the first surface impoundment, waste pile, land treatment, or 
landfill unit, or final closure if it involves such a unit, whichever is 
earlier. The owner or operator must submit the closure plan to the 
Regional Administrator at least 45 days prior to the date on which he 
expects to begin partial or final closure of a boiler or industrial 
furnace. The owner or operator must submit the closure plan to the 
Regional Administrator at least 45 days prior to the date on which he 
expects to begin final closure of a facility with only tanks, container 
storage, or incinerator units. Owners or operators with approved closure 
plans must notify the Regional Administrator in writing at least 60 days 
prior to the date on which he expects to begin closure of a surface 
impoundment, waste pile, landfill, or land treatment unit, or final 
closure of a facility involving such a unit. Owners or operators with 
approved closure plans must notify the Regional Administrator in writing 
at least 45 days prior to the date on which he expects to begin partial 
or final closure of a boiler or industrial furnace. Owners or operators 
with approved closure plans must notify the Regional Administrator in 
writing at least 45 days prior to the date on which he expects to begin 
final closure of a facility with only tanks, container storage, or 
incinerator units.

[[Page 395]]

    (2) The date when he ``expects to begin closure'' must be either:
    (i) Within 30 days after the date on which any hazardous waste 
management unit receives the known final volume of hazardous wastes, or, 
if there is a reasonable possibility that the hazardous waste management 
unit will receive additional hazardous wastes, no later than one year 
after the date on which the unit received the most recent volume of 
hazardous waste. If the owner or operator of a hazardous waste 
management unit can demonstrate to the Regional Administrator that the 
hazardous waste management unit or facility has the capacity to receive 
additional hazardous wastes and he has taken, and will continue to take, 
all steps to prevent threats to human health and the environment, 
including compliance with all interim status requirements, the Regional 
Administrator may approve an extension to this one-year limit; or
    (ii) For units meeting the requirements of Sec. 265.113(d), no later 
than 30 days after the date on which the hazardous waste management unit 
receives the known final volume of nonhazardous wastes, or if there is a 
reasonable possibility that the hazardous waste management unit will 
receive additional nonhazardous wastes, no later than one year after the 
date on which the unit received the most recent volume of nonhazardous 
wastes. If the owner or operator can demonstrate to the Regional 
Administrator that the hazardous waste management unit has the capacity 
to receive additional nonhazardous wastes and he has taken, and will 
continue to take, all steps to prevent threats to human health and the 
environment, including compliance with all applicable interim status 
requirements, the Regional Administrator may approve an extension to 
this one-year limit.
    (3) The owner or operator must submit his closure plan to the 
Regional Administrator no later than 15 days after:
    (i) Termination of interim status except when a permit is issued 
simultaneously with termination of interim status; or
    (ii) Issuance of a judicial decree or final order under section 3008 
of RCRA to cease receiving hazardous wastes or close.
    (4) The Regional Administrator will provide the owner or operator 
and the public, through a newspaper notice, the opportunity to submit 
written comments on the plan and request modifications to the plan no 
later than 30 days from the date of the notice. He will also, in 
response to a request or at his own discretion, hold a public hearing 
whenever such a hearing might clarify one or more issues concerning a 
closure plan. The Regional Administrator will give public notice of the 
hearing at least 30 days before it occurs. (Public notice of the hearing 
may be given at the same time as notice of the opportunity for the 
public to submit written comments, and the two notices may be combined.) 
The Regional Administrator will approve, modify, or disapprove the plan 
within 90 days of its receipt. If the Regional Administrator does not 
approve the plan he shall provide the owner or operator with a detailed 
written statement of reasons for the refusal and the owner or operator 
must modify the plan or submit a new plan for approval within 30 days 
after receiving such written statement. The Regional Administrator will 
approve or modify this plan in writing within 60 days. If the Regional 
Administrator modifies the plan, this modified plan becomes the approved 
closure plan. The Regional Administrator must assure that the approved 
plan is consistent with Secs.  with 265.111 through 265.115 and the 
applicable requirements of subpart F of this part, Secs. 265.197, 
265.228, 265.258, 265.280, 265.310, 265.351, 265.381, 265.404, and 
264.1102. A copy of the modified plan with a detailed statement of 
reasons for the modifications must be mailed to the owner or operator.
    (e) Removal of wastes and decontamination or dismantling of 
equipment. Nothing in this section shall preclude the owner or operator 
from removing hazardous wastes and decontaminating or dismantling 
equipment in accordance

[[Page 396]]

with the approved partial or final closure plan at any time before or 
after notification of partial or final closure.

made at least 30 days prior to the expiration of the 90-day period in 
paragraph (a) of this section; and
    (2) The demonstration in paragraph (b)(1) of this section must be 
made at least 30 days prior to the expiration of the 180-day period in 
paragraph (b) of this section, unless the owner or operator is otherwise 
subject to the deadlines in paragraph (d) of this section.
    (d) The Regional Administrator may allow an owner or operator to 
receive non-hazardous wastes in a landfill, land treatment, or surface 
impoundment unit after the final receipt of hazardous wastes at that 
unit if:
    (1) The owner or operator submits an amended part B application, or 
a part

[[Page 397]]

B application, if not previously required, and demonstrates that:
    (i) The unit has the existing design capacity as indicated on the 
part A application to receive non-hazardous wastes; and
    (ii) There is a reasonable likelihood that the owner or operator or 
another person will receive non-hazardous wastes in the unit within one 
year after the final receipt of hazardous wastes; and
    (iii) The non-hazardous wastes will not be incompatible with any 
remaining wastes in the unit or with the facility design and operating 
requirements of the unit or facility under this part; and
    (iv) Closure of the hazardous waste management unit would be 
incompatible with continued operation of the unit or facility; and
    (v) The owner or operator is operating and will continue to operate 
in compliance with all applicable interim status requirements; and
    (2) The part B application includes an amended waste analysis plan, 
ground-water monitoring and response program, human exposure assessment 
required under RCRA section 3019, and closure and post-closure plans, 
and updated cost estimates and demonstrations of financial assurance for 
closure and post-closure care as necessary and appropriate to reflect 
any changes due to the presence of hazardous constituents in the non-
hazardous wastes, and changes in closure activities, including the 
expected year of closure if applicable under Sec. 265.112(b)(7), as a 
result of the receipt of non-hazardous wastes following the final 
receipt of hazardous wastes; and
    (3) The part B application is amended, as necessary and appropriate, 
to account for the receipt of non-hazardous wastes following receipt of 
the final volume of hazardous wastes; and
    (4) The part B application and the demonstrations referred to in 
paragraphs (d)(1) and (d)(2) of this section are submitted to the 
Regional Administrator no later than 180 days prior to the date on which 
the owner or operator of the facility receives the known final volume of 
hazardous wastes, or no later than 90 days after the effective date of 
this rule in the state in which the unit is located, whichever is later.
    (e) In addition to the requirements in paragraph (d) of this 
section, an owner or operator of a hazardous waste surface impoundment 
that is not in compliance with the liner and leachate collection system 
requirements in 42 U.S.C. 3004(o)(1) and 3005(j)(1) or 42 U.S.C. 
3004(o)(2) or (3) or 3005(j) (2), (3), (4) or (13) must:
    (1) Submit with the part B application:
    (i) A contingent corrective measures plan; and
    (ii) A plan for removing hazardous wastes in compliance with 
paragraph (e)(2) of this section; and
    (2) Remove all hazardous wastes from the unit by removing all 
hazardous liquids and removing all hazardous sludges to the extent 
practicable without impairing the integrity of the liner(s), if any.
    (3) Removal of hazardous wastes must be completed no later than 90 
days after the final receipt of hazardous wastes. The Regional 
Administrator may approve an extension to this deadline if the owner or 
operator demonstrates that the removal of hazardous wastes will, of 
necessity, take longer than the allotted period to complete and that an 
extension will not pose a threat to human health and the environment.
    (4) If a release that is a statistically significant increase (or 
decrease in the case of pH) in hazardous oonstituents over background 
levels is detected in accordance with the requirements in subpart F of 
this part, the owner or operator of the unit:
    (i) Must implement corrective measures in accordance with the 
approved contingent corrective measures plan required by paragraph 
(e)(1) of this section no later than one year after detection of the 
release, or approval of the contingent corrective measures plan, 
whichever is later;
    (ii) May receive wastes at the unit following detection of the 
release only if the approved corrective measures plan includes a 
demonstration that continued receipt of wastes will not impede 
corrective action; and
    (iii) May be required by the Regional Administrator to implement 
corrective

[[Page 398]]

measures in less than one year or to cease receipt of wastes until 
corrective measures have been implemented if necessary to protect human 
health and the environment.
    (5) During the period of corrective action, the owner or operator 
shall provide semi-annual reports to the Regional Administrator that 
describe the progress of the corrective action program, compile all 
ground-water monitoring data, and evaluate the effect of the continued

    (iv) If the Regional Administrator receives written comments on the 
decision, he shall make a final decision within 30 days after the end of 
the comment period, and provide the owner or operator in writing and the 
public through a newspaper notice, a detailed statement of reasons for 
the final decision. If the Regional Administrator determines that 
substantial progress has not been made, closure must be initiated in 
accordance with the deadlines in paragraphs (a) and (b) of this section.
    (v) The final determinations made by the Regional Administrator 
under paragraphs (e)(7) (iii) and (iv) of this section are not subject 
to administrative appeal.

professional engineer's certification must be furnished to the Regional 
Administrator upon request until he releases the owner or operator from 
the financial assurance requirements for closure under Sec. 265.143(h).



Sec. 265.116  Survey plat.

    No later than the submission of the certification of closure of each 
hazardous waste disposal unit, an owner or operator must submit to the 
local zoning authority, or the authority with jurisdiction over local 
land use, and to the Regional Administrator, a survey plat indicating 
the location and dimensions of landfill cells or other hazardous waste 
disposal units with respect to permanently surveyed benchmarks. This 
plat must be prepared and certified by a professional land surveyor. The 
plat filed with the local zoning authority, or the authority with 
jurisdiction over local land use must contain a note, prominently 
displayed, which states the owner's or operator's obligation to restrict 
disturbance of the hazardous waste disposal unit in accordance with the 
applicable subpart G regulations.

accordance with the requirements of subparts F, K, L, M, and N of this 
part.
    (2) Any time preceding closure of a hazardous waste management unit 
subject to post-closure care requirements or final closure, or any time 
during the post-closure period for a particular hazardous waste disposal 
unit, the Regional Administrator may:
    (i) Shorten the post-closure care period applicable to the hazardous 
waste management unit, or facility, if all disposal units have been 
closed, if he finds that the reduced period is sufficient to protect 
human health and the environment (e.g., leachate or ground-water 
monitoring results, characteristics of the hazardous waste, application 
of advanced technology, or alternative disposal, treatment, or re-use 
techniques indicate that the hazardous waste management unit or facility 
is secure); or
    (ii) Extend the post-closure care period applicable to the hazardous 
waste management unit or facility, if he finds that the extended period 
is necessary to protect human health and the environment (e.g., leachate 
or ground-water monitoring results indicate a potential for migration of 
hazardous wastes at levels which may be harmful to human health and the 
environment).
    (b) The Regional Administator may require, at partial and final 
closure, continuation of any of the security requirements of Sec. 265.14 
during part or all of the post-closure period when:
    (1) Hazardous wastes may remain exposed after completion of partial 
or final closure; or
    (2) Access by the public or domestic livestock may pose a hazard to 
human health.
    (c) Post-closure use of property on or in which hazardous wastes 
remain after partial or final closure must never be allowed to disturb 
the integrity of the final cover, liner(s), or any other components of 
the containment system, or the function of the facility's monitoring 
systems, unless the Regional Administrator finds that the disturbance:
    (1) Is necessary to the proposed use of the property, and will not 
increase the potential hazard to human health or the environment; or
    (2) Is necessary to reduce a threat to human health or the 
environment.
    (d) All post-closure care activities must be in accordance with the 
provisions of the approved post-closure plan as specified in 
Sec. 265.118.



Sec. 265.118  Post-closure plan; amendment of plan.

    (a) Written plan. By May 19, 1981, the owner or operator of a 
hazardous waste disposal unit must have a written post-closure plan. An 
owner or operator of a surface impoundment or waste pile that intends to 
remove all hazardous

[[Page 400]]

wastes at closure must prepare a post-closure plan and submit it to the 
Regional Administrator within 90 days of the date that the owner or 
operator or Regional Administrator determines that the hazardous waste 
management unit or facility must be closed as a landfill, subject to the 
requirements of Secs. 265.117 through 265.120.
    (b) Until final closure of the facility, a copy of the most current 
post-closure plan must be furnished to the Regional Administrator upon 
request, including request by mail. In addition, for facilities without 
approved post-closure plans, it must also be provided during site 
inspections, on the day of inspection, to any officer, employee or 
representative of the Agency who is duly designated by the 
Administrator. After final closure has been certified, the person or 
office specified in Sec. 265.118(c)(3) must keep the approved post-
closure plan during the post-closure period.
    (c) For each hazardous waste management unit subject to the 
requirements of this section, the post-closure plan must identify the 
activities that will be carried on after closure of each disposal unit 
and the frequency of these activities, and include at least:
    (1) A description of the planned monitoring activities and 
frequencies at which they will be performed to comply with subparts F, 
K, L, M, and N of this part during the post-closure care period; and
    (2) A description of the planned maintenance activities, and 
frequencies at which they will be performed, to ensure:
    (i) The integrity of the cap and final cover or other containment 
systems in accordance with the requirements of subparts K, L, M, and N 
of this part; and
    (ii) The function of the monitoring equipment in accordance with the 
requirements of subparts F, K, L, M, and N of this part; and
    (3) The name, address, and phone number of the person or office to 
contact about the hazardous waste disposal unit or facility during the 
post-closure care period.
    (d) Amendment of plan. The owner or operator may amend the post-
closure plan any time during the active life of the facility or during 
the post-closure care period. An owner or operator with an approved 
post-closure plan must submit a written request to the Regional 
Administrator to authorize a change to the approved plan. The written 
request must include a copy of the amended post-closure plan for 
approval by the Regional Administrator.
    (1) The owner or operator must amend the post-closure plan whenever:
    (i) Changes in operating plans or facility design affect the post-
closure plan, or
    (ii) Events which occur during the active life of the facility, 
including partial and final closures, affect the post-closure plan.
    (2) The owner or operator must amend the post-closure plan at least 
60 days prior to the proposed change in facility design or operation, or 
no later than 60 days after an unexpected event has occurred which has 
affected the post-closure plan.
    (3) An owner or operator with an approved post-closure plan must 
submit the modified plan to the Regional Administrator at least 60 days 
prior to the proposed change in facility design or operation, or no more 
than 60 days after an unexpected event has occurred which has affected 
the post-closure plan. If an owner or operator of a surface impoundment 
or a waste pile who intended to remove all hazardous wastes at closure 
in accordance with Sec. 265.228(b) or Sec. 265.258(a) is required to 
close as a landfill in accordance with Sec. 265.310, the owner or 
operator must submit a post-closure plan within 90 days of the 
determination by the owner or operator or Regional Administrator that 
the unit must be closed as a landfill. If the amendment to the post-
closure plan is a Class 2 or 3 modification according to the criteria in 
Sec. 270.42, the modification to the plan will be approved according to 
the procedures in Sec. 265.118(f).
    (4) The Regional Administrator may request modifications to the plan 
under the conditions described in paragraph (d)(1) of this section. An 
owner or operator with an approved post-closure plan must submit the 
modified plan no later than 60 days of the request from the Regional 
Administrator. If the amendment to the plan is considered a

[[Page 401]]

Class 2 or 3 modification according to the criteria in Sec. 270.42, the 
modifications to the post-closure plan will be approved in accordance 
with the procedures in Sec. 265.118(f). If the Regional Administrator 
determines that an owner or operator of a surface impoundment or waste 
pile who intended to remove all hazardous wastes at closure must close 
the facility as a landfill, the owner or operator must submit a post-
closure plan for approval to the Regional Administrator within 90 days 
of the determination.
    (e) The owner or operator of a facility with hazardous waste 
management units subject to these requirements must submit his post-
closure plan to the Regional Administrator at least 180 days before the 
date he expects to begin partial or final closure of the first hazardous 
waste disposal unit. The date he ``expects to begin closure'' of the 
first hazardous waste disposal unit must be either within 30 days after 
the date on which the hazardous waste management unit receives the known 
final volume of hazardous waste or, if there is a reasonable possibility 
that the hazardous waste management unit will receive additional 
hazardous wastes, no later than one year after the date on which the 
unit received the most recent volume of hazardous wastes. The owner or 
operator must submit the post-closure plan to the Regional Administrator 
no later than 15 days after:
    (1) Termination of interim status (except when a permit is issued to 
the facility simultaneously with termination of interim status); or
    (2) Issuance of a judicial decree or final orders under section 3008 
of RCRA to cease receiving wastes or close.
    (f) The Regional Administrator will provide the owner or operator 
and the public, through a newspaper notice, the opportunity to submit 
written comments on the post-closure plan and request modifications to 
the plan no later than 30 days from the date of the notice. He will 
also, in response to a request or at his own discretion, hold a public 
hearing whenever such a hearing might clarify one or more issues 
concerning a post-closure plan. The Regional Administrator will give 
public notice of the hearing at least 30 days before it occurs. (Public 
notice of the hearing may be given at the same time as notice of the 
opportunity for the public to submit written comments, and the two 
notices may be combined.) The Regional Administrator will approve, 
modify, or disapprove the plan within 90 days of its receipt. If the 
Regional Administrator does not approve the plan he shall provide the 
owner or operator with a detailed written statement of reasons for the 
refusal and the owner or operator must modify the plan or submit a new 
plan for approval within 30 days after receiving such written statement. 
The Regional Administrator will approve or modify this plan in writing 
within 60 days. If the Regional Administrator modifies the plan, this 
modified plan becomes the approved post-closure plan. The Regional 
Administrator must ensure that the approved post-closure plan is 
consistent with Secs. 265.117 through 265.120. A copy of the modified 
plan with a detailed statement of reasons for the modifications must be 
mailed to the owner or operator.
    (g) The post-closure plan and length of the post-closure care period 
may be modified any time prior to the end of the post-closure care 
period in either of the following two ways:
    (1) The owner or operator or any member of the public may petition 
the Regional Administrator to extend or reduce the post-closure care 
period applicable to a hazardous waste management unit or facility based 
on cause, or alter the requirements of the post-closure care period 
based on cause.
    (i) The petition must include evidence demonstrating that:
    (A) The secure nature of the hazardous waste management unit or 
facility makes the post-closure care requirement(s) unnecessary or 
supports reduction of the post-closure care period specified in the 
current post-closure plan (e.g., leachate or ground-water monitoring 
results, characteristics of the wastes, application of advanced 
technology, or alternative disposal, treatment, or re-use techniques 
indicate that the facility is secure), or
    (B) The requested extension in the post-closure care period or 
alteration of post-closure care requirements is necessary to prevent 
threats to human

[[Page 402]]

health and the environment (e.g., leachate or ground-water monitoring 
results indicate a potential for migration of hazardous wastes at levels 
which may be harmful to human health and the environment).
    (ii) These petitions will be considered by the Regional 
Administrator only when they present new and relevant information not 
previously considered by the Regional Administrator. Whenever the 
Regional Administrator is considering a petition, he will provide the 
owner or operator and the public, through a newspaper notice, the 
opportunity to submit written comments within 30 days of the date of the 
notice. He will also, in response to a request or at his own discretion, 
hold a public hearing whenever a hearing might clarify one or more 
issues concerning the post-closure plan. The Regional Administrator will 
give the public notice of the hearing at least 30 days before it occurs. 
(Public notice of the hearing may be given at the same time as notice of 
the opportunity for written public comments, and the two notices may be 
combined.) After considering the comments, he will issue a final 
determination, based upon the criteria set forth in paragraph (g)(1) of 
this section.
    (iii) If the Regional Administrator denies the petition, he will 
send the petitioner a brief written response giving a reason for the 
denial.
    (2) The Regional Administrator may tentatively decide to modify the 
post-closure plan if he deems it necessary to prevent threats to human 
health and the environment. He may propose to extend or reduce the post-
closure care period applicable to a hazardous waste management unit or 
facility based on cause or alter the requirements of the post-closure 
care period based on cause.
    (i) The Regional Administrator will provide the owner or operator 
and the affected public, through a newspaper notice, the opportunity to 
submit written comments within 30 days of the date of the notice and the 
opportunity for a public hearing as in paragraph (g)(1)(ii) of this 
section. After considering the comments, he will issue a final 
determination.
    (ii) The Regional Administrator will base his final determination 
upon the same criteria as required for petitions under paragraph 
(g)(1)(i) of this section. A modification of the post-closure plan may 
include, where appropriate, the temporary suspension rather than 
permanent deletion of one or more post-closure care requirements. At the 
end of the specified period of suspension, the Regional Administrator 
would then determine whether the requirement(s) should be permanently 
discontinued or reinstated to prevent threats to human health and the 
environment.

Sec. 265.119  Post-closure notices.

    (a) No later than 60 days after certification of closure of each 
hazardous waste disposal unit, the owner or operator must submit to the 
local zoning authority, or the authority with jurisdiction over local 
land use, and to the Regional Administrator, a record of the type, 
location, and quantity of hazardous wastes disposed of within each cell 
or other disposal unit of the facility. For hazardous wastes disposed of 
before January 12, 1981, the owner or operator must identify the type, 
location and quantity of the hazardous wastes to the best of his 
knowledge and in accordance with any records he has kept.
    (b) Within 60 days of certification of closure of the first 
hazardous waste disposal unit and within 60 days of certification of 
closure of the last hazardous waste disposal unit, the owner or operator 
must:
    (1) Record, in accordance with State law, a notation on the deed to 
the facility property--or on some other instrument which is normally 
examined during title search--that will in perpetuity notify any 
potential purchaser of the property that:
    (i) The land has been used to manage hazardous wastes; and
    (ii) Its use is restricted under 40 CFR subpart G regulations; and
    (iii) The survey plat and record of the type, location, and quantity 
of hazardous wastes disposed of within each cell or other hazardous 
waste disposal unit of the facility required by Secs. 265.116 and 
265.119(a) have been filed with the local zoning authority or the 
authority with

[[Page 403]]

jurisdiction over local land use and with the Regional Administrator; 
and
    (2) Submit a certification signed by the owner or operator that he 
has recorded the notation specified in paragraph (b)(1) of this section 
and a copy of the document in which the notation has been placed, to the 
Regional Administrator.
    (c) If the owner or operator or any subsequent owner of the land 
upon which a hazardous waste disposal unit was located wishes to remove 
hazardous wastes and hazardous waste residues, the liner, if any, and 
all contaminated structures, equipment, and soils, he must request a 
modification to the approved post-closure plan in accordance with the 
requirements of Sec. 265.118(g). The owner or operator must demonstrate 
that the removal of hazardous wastes will satisfy the criteria of 
Sec. 265.117(c). By removing hazardous waste, the owner or operator may 
become a generator of hazardous waste and must manage it in accordance 
with all applicable requirements of this chapter. If the owner or 
operator is granted approval to conduct the removal activities, the 
owner or operator may request that the Regional Administrator approve 
either:
    (1) The removal of the notation on the deed to the facility property 
or other instrument normally examined during title search, or
    (2) The addition of a notation to the deed or instrument indicating 
the removal of the hazardous waste.



Sec. 265.120  Certification of completion of post-closure care.

    No later than 60 days after the completion of the established post-
closure care period for each hazardous waste disposal unit, the owner or 
operator must submit to the Regional Administrator, by registered mail, 
a certification that the post-closure care period for the hazardous 
waste disposal unit was performed in accordance with the specifications 
in the approved post-closure plan. The certification must be signed by 
the owner or operator and an independent registered professional 
engineer. Documentation supporting the independent registered 
professional engineer's certification must be furnished to the Regional 
Administrator upon request until he releases the owner or operator from 
the financial assurance requirements for post-closure care under 
Sec. 265.145(h).

Sec. 265.141  Definitions of terms as used in this subpart.

    (a) Closure plan means the plan for closure prepared in accordance 
with the requirements of Sec. 265.112.
    (b) Current closure cost estimate means the most recent of the 
estimates prepared in accordance with Sec. 265.142 (a), (b), and (c).
    (c) Current post-closure cost estimate means the most recent of the 
estimates prepared in accordance with Sec. 265.144 (a), (b), and (c).

in accordance with the requirements of Secs. 265.117 through 265.120.

[[Page 404]]

    (f) The following terms are used in the specifications for the 
financial tests for closure, post-closure care, and liability coverage. 
The definitions are intended to assist in the understanding of these 
regulations and are not intended to limit the meanings of terms in a way 
that conflicts with generally accepted accounting practices.
    Assets means all existing and all probable future economic benefits 
obtained or controlled by a particular entity.
    Current assets means cash or other assets or resources commonly 
identified as those which are reasonably expected to be realized in cash 
or sold or consumed during the normal operating cycle of the business.
    Current liabilities means obligations whose liquidation is 
reasonably expected to require the use of existing resources properly 
classifiable as current assets or the creation of other current 
liabilities.
    Current plugging and abandonment cost estimate means the most recent 
of the estimates prepared in accordance with Sec. 144.62(a), (b), and 
(c) of this title.
    Independently audited refers to an audit performed by an independent 
certified public accountant in accordance with generally accepted 
auditing standards.
    Liabilities means probable future sacrifices of economic benefits 
arising from present obligations to transfer assets or provide services 
to other entities in the future as a result of past transactions or 
events.
    Net working capital means current assets minus current liabilities.
    Net worth means total assets minus total liabilities and is 
equivalent to owner's equity.
    Tangible net worth means the tangible assets that remain after 
deducting liabilities; such assets would not include intangibles such as 
goodwill and rights to patents or royalties.
    (g) In the liability insurance requirements the terms bodily injury 
and property damage shall have the meanings given these terms by 
applicable State law. However, these terms do not include those 
liabilities which, consistent with standard industry practice, are 
excluded from coverage in liability policies for bodily injury and 
property damage. The Agency intends the meanings of other terms used in 
the liability insurance requirements to be consistent with their common 
meanings within the insurance industry. The definitions given below of 
several of the terms are intended to assist in the understanding of 
these regulations and are not intended to limit their meanings in a way 
that conflicts with general insurance industry usage.
    Accidental occurrence means an accident, including continuous or 
repeated exposure to conditions, which results in bodily injury or 
property damage neither expected nor intended from the standpoint of the 
insured.
    Legal defense costs means any expenses that an insurer incurs in 
defending against claims of third parties brought under the terms and 
conditions of an insurance policy.
    Nonsudden accidental occurrence means an occurrence which takes 
place over time and involves continuous or repeated exposure.
    Sudden accidental occurrence means an occurrence which is not 
continuous or repeated in nature.
    (h) Substantial business relationship means the extent of a business 
relationship necessary under applicable State law to make a guarantee 
contract issued incident to that relationship valid and enforceable. A 
``substantial business relationship'' must arise from a pattern of 
recent or ongoing business transactions, in addition to the guarantee 
itself, such that a currently existing business relationship between the 
guarantor and the owner or operator is demonstrated to the satisfaction 
of the applicable EPA Regional Administrator.

[47 FR 16558, Apr. 16, 1982, as amended at 51 FR 16456, May 2, 1986; 53 
FR 33959, Sept. 1, 1988]



Sec. 265.142  Cost estimate for closure.

    (a) The owner or operator must have a detailed written estimate, in 
current dollars, of the cost of closing the facility in accordance with 
the requirements in Secs. 265.111 through 265.115 and applicable closure 
requirements in Secs. 265.178, 265.197, 265.228, 265.258, 265.280, 
265.310, 265.351, 265.381, 265.404, and 265.1102.

[[Page 405]]

    (1) The estimate must equal the cost of final closure at the point 
in the facility's active life when the extent and manner of its 
operation would make closure the most expensive, as indicated by its 
closure plan (see Sec. 265.112(b)); and
    (2) The closure cost estimate must be based on the costs to the 
owner or operator of hiring a third party to close the facility. A third 
party is a party who is neither a parent nor a subsidiary of the owner 
or operator. (See definition of parent corporation in Sec. 265.141(d).) 
The owner or operator may use costs for on-site disposal if he can 
demonstrate that on-site disposal capacity will exist at all times over 
the life of the facility.
    (3) The closure cost estimate may not incorporate any salvage value 
that may be realized with the sale of hazardous wastes, or non-hazardous 
wastes if applicable under Sec. 265.113(d), facility structures or 
equipment, land, or other assets associated with the facility at the 
time of partial or final closure.
    (4) The owner or operator may not incorporate a zero cost for 
hazardous wastes, or non-hazardous wastes if applicable under 
Sec. 265.113(d), that might have economic value.
    (b) During the active life of the facility, the owner or operator 
must adjust the closure cost estimate for inflation within 60 days prior 
to the anniversary date of the establishment of the financial 
instrument(s) used to comply with Sec. 265.143. For owners and operators 
using the financial test or corporate guarantee, the closure cost 
estimate must be updated for inflation within 30 days after the close of 
the firm's fiscal year and before submission of updated information to 
the Regional Administrator as specified in Sec. 265.143(e)(3). The 
adjustment may be made by recalculating the closure cost estimate in 
current dollars, or by using an inflation factor derived from the most 
recent Implicit Price Deflator for Gross National Product published by 
the U.S. Department of Commerce in its Survey of Current Business, as 
specified in paragraphs (b)(1) and (2) of this section. The inflation 
factor is the result of dividing the latest published annual Deflator by 
the Deflator for the previous year.
    (1) The first adjustment is made by multiplying the closure cost 
estimate by the inflation factor. The result is the adjusted closure 
cost estimate.
    (2) Subsequent adjustments are made by multiplying the latest 
adjusted closure cost estimate by the latest inflation factor.
    (c) During the active life of the facility, the owner or operator 
must revise the closure cost estimate no later than 30 days after a 
revision has been made to the closure plan which increases the cost of 
closure. If the owner or operator has an approved closure plan, the 
closure cost estimate must be revised no later than 30 days after the 
Regional Administrator has approved the request to modify the closure 
plan, if the change in the closure plan increases the cost of closure. 
The revised closure cost estimate must be adjusted for inflation as 
specified in Sec. 265.142(b).
    (d) The owner or operator must keep the following at the facility 
during the operating life of the facility: The latest closure cost 
estimate prepared in accordance with Secs. 265.142 (a) and (c) and, when 
this estimate has been adjusted in accordance with Sec. 265.142(b), the 
latest adjusted closure cost estimate.

Sec. 265.143  Financial assurance for closure.

    By the effective date of these regulations, an owner or operator of 
each facility must establish financial assurance for closure of the 
facility. He must choose from the options as specified in paragraphs (a) 
through (e) of this section.
    (a) Closure trust fund. (1) An owner or operator may satisfy the 
requirements of this section by establishing a closure trust fund which 
conforms to the requirements of this paragraph and submitting an 
originally signed duplicate of the trust agreement to the Regional 
Administrator. The trustee must be an entity which has the authority to 
act as a trustee and whose trust operations are regulated and examined 
by a Federal or State agency.
    (2) The wording of the trust agreement must be identical to the 
wording

[[Page 406]]

specified in Sec. 264.151(a)(1), and the trust agreement must be 
accompanied by a formal certification of acknowledgment (for example, 
see Sec. 264.151(a)(2)). Schedule A of the trust agreement must be 
updated within 60 days after a change in the amount of the current 
closure cost estimate covered by the agreement.
    (3) Payments into the trust fund must be made annually by the owner 
or operator over the 20 years beginning with the effective date of these 
regulations or over the remaining operating life of the facility as 
estimated in the closure plan, whichever period is shorter; this period 
is hereafter referred to as the ``pay-in period.'' The payments into the 
closure trust fund must be made as follows:
    (i) The first payment must be made by the effective date of these 
regulations, except as provided in paragraph (a)(5) of this section. The 
first payment must be at least equal to the current closure cost 
estimate, except as provided in Sec. 265.143(f), divided by the number 
of years in the pay-in period.
    (ii) Subsequent payments must be made no later than 30 days after 
each anniversary date of the first payment. The amount of each 
subsequent payment must be determined by this formula:
[GRAPHIC] [TIFF OMITTED] TC01AU92.050

where CE is the current closure cost estimate, CV is the current value 
of the trust fund, and Y is the number of years remaining in the pay-in 
period.
    (4) The owner or operator may accelerate payments into the trust 
fund or he may deposit the full amount of the current closure cost 
estimate at the time the fund is established. However, he must maintain 
the value of the fund at no less than the value that the fund would have 
if annual payments were made as specified in paragraph (a)(3) of this 
section.
    (5) If the owner or operator establishes a closure trust fund after 
having used one or more alternate mechanisms specified in this section, 
his first payment must be in at least the amount that the fund would 
contain if the trust fund were established initially and annual payments 
made as specified in paragraph (a)(3) of this section.
    (6) After the pay-in period is completed, whenever the current 
closure cost estimate changes, the owner or operator must compare the 
new estimate with the trustee's most recent annual valuation of the 
trust fund. If the value of the fund is less than the amount of the new 
estimate, the owner or operator, within 60 days after the change in the 
cost estimate, must either deposit an amount into the fund so that its 
value after this deposit at least equals the amount of the current 
closure cost estimate, or obtain other financial assurance as specified 
in this section to cover the difference.
    (7) If the value of the trust fund is greater than the total amount 
of the current closure cost estimate, the owner or operator may submit a 
written request to the Regional Administrator for release of the amount 
in excess of the current closure cost estimate.
    (8) If an owner or operator substitutes other financial assurance as 
specified in this section for all or part of the trust fund, he may 
submit a written request to the Regional Administrator for release of 
the amount in excess of the current closure cost estimate covered by the 
trust fund.
    (9) Within 60 days after receiving a request from the owner or 
operator for release of funds as specified in paragraph (a) (7) or (8) 
of this section, the Regional Administrator will instruct the trustee to 
release to the owner or operator such funds as the Regional 
Administrator specifies in writing.
    (10) After beginning partial or final closure, an owner or operator 
or another person authorized to conduct partial or final closure may 
request reimbursements for partial or final closure expenditures by 
submitting itemized bills to the Regional Administrator. The owner or 
operator may request reimbursements for partial closure only if 
sufficient funds are remaining in the trust fund to cover the maximum 
costs of closing the facility over its remaining operating life. No 
later than 60 days after receiving bills for partial or final closure 
activities,

[[Page 407]]

the Regional Administrator will instruct the trustee to make 
reimbursements in those amounts as the Regional Administrator specifies 
in writing, if the Regional Administrator determines that the partial or 
final closure expenditures are in accordance with the approved closure 
plan, or otherwise justified. If the Regional Administrator has reason 
to believe that the maximum cost of closure over the remaining life of 
the facility will be significantly greater than the value of the trust 
fund, he may withhold reimbursements of such amounts as he deems prudent 
until he determines, in accordance with Sec. 265.143(h) that the owner 
or operator is no longer required to maintain financial assurance for 
final closure of the facility. If the Regional Administrator does not 
instruct the trustee to make such reimbursements, he will provide to the 
owner or operator a detailed written statement of reasons.
    (11) The Regional Administrator will agree to termination of the 
trust when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 265.143(h).
    (b) Surety bond guaranteeing payment into a closure trust fund. (1) 
An owner or operator may satisfy the requirements of this section by 
obtaining a surety bond which conforms to the requirements of this 
paragraph and submitting the bond to the Regional Administrator. The 
surety company issuing the bond must, at a minimum, be among those 
listed as acceptable sureties on Federal bonds in Circular 570 of the 
U.S. Department of the Treasury.
    (2) The wording of the surety bond must be identical to the wording 
specified in Sec. 264.151(b).
    (3) The owner or operator who uses a surety bond to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the bond, all payments made thereunder will be 
deposited by the surety directly into the standby trust fund in 
accordance with instructions from the Regional Administrator. This 
standby trust fund must meet the requirements specified in 
Sec. 265.143(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the surety bond; and
    (ii) Until the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:
    (A) Payments into the trust fund as specified in Sec. 265.143(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The bond must guarantee that the owner or operator will:
    (i) Fund the standby trust fund in an amount equal to the penal sum 
of the bond before the beginning of final closure of the facility; or
    (ii) Fund the standby trust fund in an amount equal to the penal sum 
within 15 days after an administrative order to begin final closure 
issued by the Regional Administrator becomes final, or within 15 days 
after an order to begin final closure is issued by a U.S. district court 
or other court of competent jurisdiction; or
    (iii) Provide alternate financial assurance as specified in this 
section, and obtain the Regional Administrator's written approval of the 
assurance provided, within 90 days after receipt by both the owner or 
operator and the Regional Administrator of a notice of cancellation of 
the bond from the surety.
    (5) Under the terms of the bond, the surety will become liable on 
the bond obligation when the owner or operator fails to perform as 
guaranteed by the bond.
    (6) The penal sum of the bond must be in an amount at least equal to 
the current closure cost estimate, except as provided in 
Sec. 265.143(f).
    (7) Whenever the current closure cost estimate increases to an 
amount greater than the penal sum, the owner or operator, within 60 days 
after the increase, must either cause the penal sum to be increased to 
an amount at least equal to the current closure cost

[[Page 408]]

estimate and submit evidence of such increase to the Regional 
Administrator, or obtain other financial assurance as specified in this 
section to cover the increase. Whenever the current closure cost 
estimate decreases, the penal sum may be reduced to the amount of the 
current closure cost estimate following written approval by the Regional 
Administrator.
    (8) Under the terms of the bond, the surety may cancel the bond by 
sending notice of cancellation by certified mail to the owner or 
operator and to the Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (9) The owner or operator may cancel the bond if the Regional 
Administrator has given prior written consent based on his receipt of 
evidence of alternate financial assurance as specified in this section.
    (c) Closure letter of credit. (1) An owner or operator may satisfy 
the requirements of this section by obtaining an irrevocable standby 
letter of credit which conforms to the requirements of this paragraph 
and submitting the letter to the Regional Administrator. The issuing 
institution must be an entity which has the authority to issue letters 
of credit and whose letter-of-credit operations are regulated and 
examined by a Federal or State agency.
    (2) The wording of the letter of credit must be identical to the 
wording specified in Sec. 264.151(d).
    (3) An owner or operator who uses a letter of credit to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the letter of credit, all amounts paid pursuant to a 
draft by the Regional Administrator will be deposited by the issuing 
institution directly into the standby trust fund in accordance with 
instructions from the Regional Administrator. This standby trust fund 
must meet the requirements of the trust fund specified in 
Sec. 265.143(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the letter of credit; and
    (ii) Unless the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:
    (A) Payments into the trust fund as specified in Sec. 265.143(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The letter of credit must be accompanied by a letter from the 
owner or operator referring to the letter of credit by number, issuing 
institution, and date, and providing the following information: The EPA 
Identification Number, name, and address of the facility, and the amount 
of funds assured for closure of the facility by the letter of credit.
    (5) The letter of credit must be irrevocable and issued for a period 
of at least 1 year. The letter of credit must provide that the 
expiration date will be automatically extended for a period of at least 
1 year unless, at least 120 days before the current expiration date, the 
issuing institution notifies both the owner or operator and the Regional 
Administrator by certified mail of a decision not to extend the 
expiration date. Under the terms of the letter of credit, the 120 days 
will begin on the date when both the owner or operator and the Regional 
Administrator have received the notice, as evidenced by the return 
receipts.
    (6) The letter of credit must be issued in an amount at least equal 
to the current closure cost estimate, except as provided in 
Sec. 265.143(f).
    (7) Whenever the current closure cost estimate increases to an 
amount greater than the amount of the credit, the owner or operator, 
within 60 days after the increase, must either cause the amount of the 
credit to be increased so that it at least equals the current closure 
cost estimate and submit evidence of such increase to the Regional 
Administrator, or obtain other financial assurance as specified in this 
section to cover the increase. Whenever the current closure cost 
estimate decreases,

[[Page 409]]

the amount of the credit may be reduced to the amount of the current 
closure cost estimate following written approval by the Regional 
Administrator.
    (8) Following a final administrative determination pursuant to 
section 3008 of RCRA that the owner or operator has failed to perform 
final closure in accordance with the approved closure plan when required 
to do so, the Regional Administrator may draw on the letter of credit.
    (9) If the owner or operator does not establish alternate financial 
assurance as specified in this section and obtain written approval of 
such alternate assurance from the Regional Administrator within 90 days 
after receipt by both the owner or operator and the Regional 
Administrator of a notice from the issuing institution that it has 
decided not to extend the letter of credit beyond the current expiration 
date, the Regional Administrator will draw on the letter of credit. The 
Regional Administrator may delay the drawing if the issuing institution 
grants an extension of the term of the credit. During the last 30 days 
of any such extension the Regional Administrator will draw on the letter 
of credit if the owner or operator has failed to provide alternate 
financial assurance as specified in this section and obtain written 
approval of such assurance from the Regional Administrator.
    (10) The Regional Administrator will return the letter of credit to 
the issuing institution for termination when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 265.143(h).
    (d) Closure insurance. (1) An owner or operator may satisfy the 
requirements of this section by obtaining closure insurance which 
conforms to the requirements of this paragraph and submitting a 
certificate of such insurance to the Regional Administrator. By the 
effective date of these regulations the owner or operator must submit to 
the Regional Administrator a letter from an insurer stating that the 
insurer is considering issuance of closure insurance conforming to the 
requirements of this paragraph to the owner or operator. Within 90 days 
after the effective date of these regulations, the owner or operator 
must submit the certificate of insurance to the Regional Administrator 
or establish other financial assurance as specified in this section. At 
a minimum, the insurer must be licensed to transact the business of 
insurance, or eligible to provide insurance as an excess or surplus 
lines insurer, in one or more States.
    (2) The wording of the certificate of insurance must be identical to 
the wording specified in Sec. 264.151(e).
    (3) The closure insurance policy must be issued for a face amount at 
least equal to the current closure cost estimate, except as provided in 
Sec. 265.143(f). The term ``face amount'' means the total amount the 
insurer is obligated to pay under the policy. Actual payments by the 
insurer will not change the face amount, although the insurer's future 
liability will be lowered by the amount of the payments.
    (4) The closure insurance policy must guarantee that funds will be 
available to close the facility whenever final closure occurs. The 
policy must also guarantee that once final closure begins, the insurer 
will be responsible for paying out funds, up to an amount equal to the 
face amount of the policy, upon the direction of the Regional 
Administrator, to such party or parties as the Regional Administrator 
specifies.
    (5) After beginning partial or final closure, an owner or operator 
or any other person authorized to conduct closure may request 
reimbursements for closure expenditures by submitting itemized bills to 
the Regional Administrator. The owner or operator may request 
reimbursements for partial closure only if the remaining value of the 
policy is sufficient to cover the maximum costs of closing the facility 
over its remaining operating life. Within 60 days after receiving bills 
for closure activities, the Regional Administrator will instruct the 
insurer to make reimbursements in such amounts as the Regional 
Administrator specifies in writing if the Regional Administrator 
determines that the partial or final closure expenditures are in 
accordance

[[Page 410]]

with the approved closure plan or otherwise justified. If the Regional 
Administrator has reason to believe that the maximum cost of closure 
over the remaining life of the facility will be significantly greater 
than the face amount of the policy, he may withhold reimbursement of 
such amounts as he deems prudent until he determines, in accordance with 
Sec. 265.143(h), that the owner or operator is no longer required to 
maintain financial assurance for final closure of the particular 
facility. If the Regional Administrator does not instruct the insurer to 
make such reimbursements, he will provide to the owner or operator a 
detailed written statement of reasons.
    (6) The owner or operator must maintain the policy in full force and 
effect until the Regional Administrator consents to termination of the 
policy by the owner or operator as specified in paragraph (d)(10) of 
this section. Failure to pay the premium, without substitution of 
alternate financial assurance as specified in this section, will 
constitute a significant violation of these regulations, warranting such 
remedy as the Regional Administrator deems necessary. Such violation 
will be deemed to begin upon receipt by the Regional Administrator of a 
notice of future cancellation, termination, or failure to renew due to 
nonpayment of the premium, rather than upon the date of expiration.
    (7) Each policy must contain a provision allowing assignment of the 
policy to a successor owner or operator. Such assignment may be 
conditional upon consent of the insurer, provided such consent is not 
unreasonably refused.
    (8) The policy must provide that the insurer may not cancel, 
terminate, or fail to renew the policy except for failure to pay the 
premium. The automatic renewal of the policy must, at a minimum, provide 
the insured with the option of renewal at the face amount of the 
expiring policy. If there is a failure to pay the premium, the insurer 
may elect to cancel, terminate, or fail to renew the policy by sending 
notice by certified mail to the owner or operator and the Regional 
Administrator. Cancellation, termination, or failure to renew may not 
occur, however, during the 120 days beginning with the date of receipt 
of the notice by both the Regional Administrator and the owner or 
operator, as evidenced by the return receipts. Cancellation, 
termination, or failure to renew may not occur and the policy will 
remain in full force and effect in the event that on or before the date 
of expiration:
    (i) The Regional Administrator deems the facility abandoned; or
    (ii) Interim status is terminated or revoked; or
    (iii) Closure is ordered by the Regional Administrator or a U.S. 
district court or other court of competent jurisdiction; or
    (iv) The owner or operator is named as debtor in a voluntary or 
involuntary proceeding under Title 11 (Bankruptcy), U.S. Code; or
    (v) The premium due is paid.
    (9) Whenever the current closure cost estimate increases to an 
amount greater than the face amount of the policy, the owner or 
operator, within 60 days after the increase, must either cause the face 
amount to be increased to an amount at least equal to the current 
closure cost estimate and submit evidence of such increase to the 
Regional Administrator, or obtain other financial assurance as specified 
in this section to cover the increase. Whenever the current closure cost 
estimate decreases, the face amount may be reduced to the amount of the 
current closure cost estimate following written approval by the Regional 
Administrator.
    (10) The Regional Administrator will give written consent to the 
owner or operator that he may terminate the insurance policy when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 265.143(h).
    (e) Financial test and corporate guarantee for closure. (1) An owner 
or operator may satisfy the requirements of this section by 
demonstrating that he passes a financial test as specified in this 
paragraph. To pass this test the owner or operator must meet the 
criteria of either paragraph (e)(1)(i) or (ii) of this section:

[[Page 411]]

    (i) The owner or operator must have:
    (A) Two of the following three ratios: A ratio of total liabilities 
to net worth less than 2.0; a ratio of the sum of net income plus 
depreciation, depletion, and amortization to total liabilities greater 
than 0.1; and a ratio of current assets to current liabilities greater 
than 1.5; and
    (B) Net working capital and tangible net worth each at least six 
times the sum of the current closure and post-closure cost estimates and 
the current plugging and abandonment cost estimates; and
    (C) Tangible net worth of at least $10 million; and
    (D) Assets located in the United States amounting to at least 90 
percent of total assets or at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates.
    (ii) The owner or operator must have:
    (A) A current rating for his most recent bond issuance of AAA, AA, 
A, or BBB as issued by Standard and Poor's or Aaa, Aa, A, or Baa as 
issued by Moody's; and
    (B) Tangible net worth at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates; and
    (C) Tangible net worth of at least $10 million; and
    (D) Assets located in the United States amounting to at least 90 
percent of total assets or at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates.
    (2) The phrase ``current closure and post-closure cost estimates'' 
as used in paragraph (e)(1) of this section refers to the cost estimates 
required to be shown in paragraphs 1-4 of the letter from the owner's or 
operator's chief financial officer (Sec. 264.151(f)). The phrase 
``current plugging and abandonment cost estimates'' as used in paragraph 
(e)(1) of this section refers to the cost estimates required to be shown 
in paragraphs 1-4 of the letter from the owner's or operator's chief 
financial officer (Sec. 144.70(f) of this title).
    (3) To demonstrate that he meets this test, the owner or operator 
must submit the following items to the Regional Administrator:
    (i) A letter signed by the owner's or operator's chief financial 
officer and worded as specified in Sec. 264.151(f); and
    (ii) A copy of the independent certified public accountant's report 
on examination of the owner's or operator's financial statements for the 
latest completed fiscal year; and
    (iii) A special report from the owner's or operator's independent 
certified public accountant to the owner or operator stating that:
    (A) He has compared the data which the letter from the chief 
financial officer specifies as having been derived from the 
independently audited, year-end financial statements for the latest 
fiscal year with the amounts in such financial statements; and
    (B) In connection with that procedure, no matters came to his 
attention which caused him to believe that the specified data should be 
adjusted.
    (4) The owner or operator may obtain an extension of the time 
allowed for submission of the documents specified in paragraph (e)(3) of 
this section if the fiscal year of the owner or operator ends during the 
90 days prior to the effective date of these regulations and if the 
year-end financial statements for that fiscal year will be audited by an 
independent certified public accountant. The extension will end no later 
than 90 days after the end of the owner's or operator's fiscal year. To 
obtain the extension, the owner's or operator's chief financial officer 
must send, by the effective date of these regulations, a letter to the 
Regional Administrator of each Region in which the owner's or operator's 
facilities to be covered by the financial test are located. This letter 
from the chief financial officer must:
    (i) Request the extension;
    (ii) Certify that he has grounds to believe that the owner or 
operator meets the criteria of the financial test;
    (iii) Specify for each facility to be covered by the test the EPA 
Identification Number, name, address, and current closure and post-
closure cost estimates to be covered by the test;

[[Page 412]]

    (iv) Specify the date ending the owner's or operator's last complete 
fiscal year before the effective date of these regulations;
    (v) Specify the date, no later than 90 days after the end of such 
fiscal year, when he will submit the documents specified in paragraph 
(e)(3) of this section; and
    (vi) Certify that the year-end financial statements of the owner or 
operator for such fiscal year will be audited by an independent 
certified public accountant.
    (5) After the initial submission of items specified in paragraph 
(e)(3) of this section, the owner or operator must send updated 
information to the Regional Administrator within 90 days after the close 
of each succeeding fiscal year. This information must consist of all 
three items specified in paragraph (e)(3) of this section.
    (6) If the owner or operator no longer meets the requirements of 
paragraph (e)(1) of this section, he must send notice to the Regional 
Administrator of intent to establish alternate financial assurance as 
specified in this section. The notice must be sent by certified mail 
within 90 days after the end of the fiscal year for which the year-end 
financial data show that the owner or operator no longer meets the 
requirements. The owner or operator must provide the alternate financial 
assurance within 120 days after the end of such fiscal year.
    (7) The Regional Administrator may, based on a reasonable belief 
that the owner or operator may no longer meet the requirements of 
paragraph (e)(1) of this section, require reports of financial condition 
at any time from the owner or operator in addition to those specified in 
paragraph (e)(3) of this section. If the Regional Administrator finds, 
on the basis of such reports or other information, that the owner or 
operator no longer meets the requirements of paragraph (e)(1) of this 
section, the owner or operator must provide alternate financial 
assurance as specified in this section within 30 days after notification 
of such a finding.
    (8) The Regional Administrator may disallow use of this test on the 
basis of qualifications in the opinion expressed by the independent 
certified public accountant in his report on examination of the owner's 
or operator's financial statements (see paragraph (e)(3)(ii) of this 
section). An adverse opinion or a disclaimer of opinion will be cause 
for disallowance. The Regional Administrator will evaluate other 
qualifications on an individual basis. The owner or operator must 
provide alternate financial assurance as specified in this section 
within 30 days after notification of the disallowance.
    (9) The owner or operator is no longer required to submit the items 
specified in paragraph (e)(3) of this section when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 265.143(h).
    (10) An owner or operator may meet the requirements of this section 
by obtaining a written guarantee. The guarantor must be the direct or 
higher-tier parent corporation of the owner or operator, a firm whose 
parent corporation is also the parent corporation of the owner or 
operator, or a firm with a ``substantial business relationship'' with 
the owner or operator. The guarantor must meet the requirements for 
owners or operators in paragraphs (e)(1) through (8) of this section and 
must comply with the terms of the guarantee. The wording of the 
guarantee must be identical to the wording specified in Sec. 264.151(h). 
A certified copy of the guarantee must accompany the items sent to the 
Regional Administrator as specified in paragraph (e)(3) of this section. 
One of these items must be the letter from the guarantor's chief 
financial officer. If the guarantor's parent corporation is also the 
parent corporation of the owner or operator, the letter must describe 
the value received in consideration of the guarantee. If the guarantor 
is a firm with a ``substantial business relationship'' with the owner or 
operator, this letter must describe this ``substantial business 
relationship'' and the value received in consideration of the guarantee. 
The terms of the guarantee must provide that:

[[Page 413]]

    (i) If the owner or operator fails to perform final closure of a 
facility covered by the corporate guarantee in accordance with the 
closure plan and other interim status requirements whenever required to 
do so, the guarantor will do so or establish a trust fund as specified 
in Sec. 265.143(a) in the name of the owner or operator.
    (ii) The corporate guarantee will remain in force unless the 
guarantor sends notice of cancellation by certified mail to the owner or 
operator and to the Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (iii) If the owner or operator fails to provide alternate financial 
assurance as specified in this section and obtain the written approval 
of such alternate assurance from the Regional Administrator within 90 
days after receipt by both the owner or operator and the Regional 
Administrator of a notice of cancellation of the corporate guarantee 
from the guarantor, the guarantor will provide such alternate financial 
assurance in the name of the owner or operator.
    (f) Use of multiple financial mechanisms. An owner or operator may 
satisfy the requirements of this section by establishing more than one 
financial mechanism per facility. These mechanisms are limited to trust 
funds, surety bonds, letters of credit, and insurance. The mechanisms 
must be as specified in paragraphs (a) through (d), respectively, of 
this section, except that it is the combination of mechanisms, rather 
than the single mechanism, which must provide financial assurance for an 
amount at least equal to the current closure cost estimate. If an owner 
or operator uses a trust fund in combination with a surety bond or a 
letter of credit, he may use the trust fund as the standby trust fund 
for the other mechanisms. A single standby trust fund may be established 
for two or more mechanisms. The Regional Administrator may use any or 
all of the mechanisms to provide for closure of the facility.
    (g) Use of a financial mechanism for multiple facilities. An owner 
or operator may use a financial assurance mechanism specified in this 
section to meet the requirements of this section for more than one 
facility. Evidence of financial assurance submitted to the Regional 
Administrator must include a list showing, for each facility, the EPA 
Identification Number, name, address, and the amount of funds for 
closure assured by the mechanism. If the facilities covered by the 
mechanism are in more than one Region, identical evidence of financial 
assurance must be submitted to and maintained with the Regional 
Administrators of all such Regions. The amount of funds available 
through the mechanism must be no less than the sum of funds that would 
be available if a separate mechanism had been established and maintained 
for each facility. In directing funds available through the mechanism 
for closure of any of the facilities covered by the mechanism, the 
Regional Administrator may direct only the amount of funds designated 
for that facility, unless the owner or operator agrees to the use of 
additional funds available under the mechanism.
    (h) Release of the owner or operator from the requirements of this 
section. Within 60 days after receiving certifications from the owner or 
operator and an independent registered professional engineer that final 
closure has been completed in accordance with the approved closure plan, 
the Regional Administrator will notify the owner or operator in writing 
that he is no longer required by this section to maintain financial 
assurance for final closure of the facility, unless the Regional 
Administrator has reason to believe that final closure has not been in 
accordance with the approved closure plan. The Regional Administrator 
shall provide the owner or operator a detailed written statement of any 
such reason to believe that closure has not been in accordance with the 
approved closure plan.

Sec. 265.144  Cost estimate for post-closure care.

    (a) The owner or operator of a hazardous waste disposal unit must 
have a detailed written estimate, in current dollars, of the annual cost 
of post-closure monitoring and maintenance of the facility in accordance 
with the applicable post-closure regulations in Secs. 265.117 through 
265.120, 265.228, 265.258, 265.280, and 265.310.
    (1) The post-closure cost estimate must be based on the costs to the 
owner or operator of hiring a third party to conduct post-closure care 
activities. A third party is a party who is neither a parent nor 
subsidiary of the owner or operator. (See definition of parent 
corporation in Sec. 265.141(d).)
    (2) The post-closure cost estimate is calculated by multiplying the 
annual post-closure cost estimate by the number of years of post-closure 
care required under Sec. 265.117.
    (b) During the active life of the facility, the owner or operator 
must adjust the post-closure cost estimate for inflation within 60 days 
prior to the anniversary date of the establishment of the financial 
instrument(s) used to comply with Sec. 265.145. For owners or operators 
using the financial test or corporate guarantee, the post-closure care 
cost estimate must be updated for inflation no later than 30 days after 
the close of the firm's fiscal year and before submission of updated 
information to the Regional Administrator as specified in 
Sec. 265.145(d)(5). The adjustment may be made by recalculating the 
post-closure cost estimate in current dollars or by using an inflation 
factor derived from the most recent Implicit Price Deflator for Gross 
National Product published by the U.S. Department of Commerce in its 
Survey of Current Business as specified in Sec. 265.145 (b)(1) and (2). 
The inflation factor is the result of dividing the latest published 
annual Deflator by the Deflator for the previous year.
    (1) The first adjustment is made by multiplying the post-closure 
cost estimate by the inflation factor. The result is the adjusted post-
closure cost estimate.
    (2) Subsequent adjustments are made by multiplying the latest 
adjusted post-closure cost estimate by the latest inflation factor.
    (c) During the active life of the facility, the owner or operator 
must revise the post-closure cost estimate no later than 30 days after a 
revision to the post-closure plan which increases the cost of post-
closure care. If the owner or operator has an approved post-closure 
plan, the post-closure cost estimate must be revised no later than 30 
days after the Regional Administrator has approved the request to modify 
the plan, if the change in the post-closure plan increases the cost of 
post-closure care. The revised post-closure cost estimate must be 
adjusted for inflation as specified in Sec. 265.144(b).
    (d) The owner or operator must keep the following at the facility 
during the operating life of the facility: the latest post-closure cost 
estimate prepared in accordance with Sec. 265.144 (a) and (c) and, when 
this estimate has been adjusted in accordance with Sec. 265.144(b), the 
latest adjusted post-closure cost estimate.

Sec. 265.145  Financial assurance for post-closure care.

    By the effective date of these regulations, an owner or operator of 
a facility with a hazardous waste disposal unit must establish financial 
assurance for post-closure care of the disposal unit(s).
    (a) Post-closure trust fund. (1) An owner or operator may satisfy 
the requirements of this section by establishing a post-closure trust 
fund which conforms to the requirements of this paragraph and submitting 
an originally signed duplicate of the trust agreement to the Regional 
Administrator. The trustee must be an entity which has the authority to 
act as a trustee and whose trust operations are regulated and examined 
by a Federal or State agency.
    (2) The wording of the trust agreement must be identical to the 
wording specified in Sec. 264.151(a)(1), and the trust agreement must be 
accompanied by a formal certification of acknowledgment (for example, 
see Sec. 264.151(a)(2)). Schedule A of the trust agreement

[[Page 415]]

must be updated within 60 days after a change in the amount of the 
current post-closure cost estimate covered by the agreement.
    (3) Payments into the trust fund must be made annually by the owner 
or operator over the 20 years beginning with the effective date of these 
regulations or over the remaining operating life of the facility as 
estimated in the closure plan, whichever period is shorter; this period 
is hereafter referred to as the ``pay-in period.'' The payments into the 
post-closure trust fund must be made as follows:
    (i) The first payment must be made by the effective date of these 
regulations, except as provided in paragraph (a)(5) of this section. The 
first payment must be at least equal to the current post-closure cost 
estimate, except as provided in Sec. 265.145(f), divided by the number 
of years in the pay-in period.
    (ii) Subsequent payments must be made no later than 30 days after 
each anniversary date of the first payment. The amount of each 
subsequent payment must be determined by this formula:
[GRAPHIC] [TIFF OMITTED] TC01AU92.050

where CE is the current post-closure cost estimate, CV is the current 
value of the trust fund, and Y is the number of years remaining in the 
pay-in period.
    (4) The owner or operator may accelerate payments into the trust 
fund or he may deposit the full amount of the current post-closure cost 
estimate at the time the fund is established. However, he must maintain 
the value of the fund at no less than the value that the fund would have 
if annual payments were made as specified in paragraph (a)(3) of this 
section.
    (5) If the owner or operator establishes a post-closure trust fund 
after having used one or more alternate mechanisms specified in this 
section, his first payment must be in at least the amount that the fund 
would contain if the trust fund were established initially and annual 
payments made as specified in paragraph (a)(3) of this section.
    (6) After the pay-in period is completed, whenever the current post-
closure cost estimate changes during the operating life of the facility, 
the owner or operator must compare the new estimate with the trustee's 
most recent annual valuation of the trust fund. If the value of the fund 
is less than the amount of the new estimate, the owner or operator, 
within 60 days after the change in the cost estimate, must either 
deposit an amount into the fund so that its value after this deposit at 
least equals the amount of the current post-closure cost estimate, or 
obtain other financial assurance as specified in this section to cover 
the difference.
    (7) During the operating life of the facility, if the value of the 
trust fund is greater than the total amount of the current post-closure 
cost estimate, the owner or operator may submit a written request to the 
Regional Administrator for release of the amount in excess of the 
current post-closure cost estimate.
    (8) If an owner or operator substitutes other financial assurance as 
specified in this section for all or part of the trust fund, he may 
submit a written request to the Regional Administrator for release of 
the amount in excess of the current post-closure cost estimate covered 
by the trust fund.
    (9) Within 60 days after receiving a request from the owner or 
operator for release of funds as specified in paragraph (a) (7) or (8) 
of this section, the Regional Administrator will instruct the trustee to 
release to the owner or operator such funds as the Regional 
Administrator specifies in writing.
    (10) During the period of post-closure care, the Regional 
Administrator may approve a release of funds if the owner or operator 
demonstrates to the Regional Administrator that the value of the trust 
fund exceeds the remaining cost of post-closure care.
    (11) An owner or operator or any other person authorized to conduct 
post-closure care may request reimbursements for post-closure 
expenditures by submitting itemized bills to the Regional Administrator. 
Within 60 days after receiving bills for post-closure care activities, 
the Regional Administrator will instruct the trustee to make 
reimbursements in those

[[Page 416]]

amounts as the Regional Administrator specifies in writing, if the 
Regional Administrator determines that the post-closure expenditures are 
in accordance with the approved post-closure plan or otherwise 
justified. If the Regional Administrator does not instruct the trustee 
to make such reimbursements, he will provide the owner or operator with 
a detailed written statement of reasons.
    (12) The Regional Administrator will agree to termination of the 
trust when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 265.145(h).
    (b) Surety bond guaranteeing payment into a post-closure trust fund. 
(1) An owner or operator may satisfy the requirements of this section by 
obtaining a surety bond which conforms to the requirements of this 
paragraph and submitting the bond to the Regional Administrator. The 
surety company issuing the bond must, at a minimum, be among those 
listed as acceptable sureties on Federal bonds in Circular 570 of the 
U.S. Department of the Treasury.
    (2) The wording of the surety bond must be identical to the wording 
specified in Sec. 264.151(b).
    (3) The owner or operator who uses a surety bond to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the bond, all payments made thereunder will be 
deposited by the surety directly into the standby trust fund in 
accordance with instructions from the Regional Administrator. This 
standby trust fund must meet the requirements specified in 
Sec. 265.145(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the surety bond; and
    (ii) Until the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:
    (A) Payments into the trust fund as specified in Sec. 265.145(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current post-closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The bond must guarantee that the owner or operator will:
    (i) Fund the standby trust fund in an amount equal to the penal sum 
of the bond before the beginning of final closure of the facility; or
    (ii) Fund the standby trust fund in an amount equal to the penal sum 
within 15 days after an administrative order to begin final closure 
issued by the Regional Administrator becomes final, or within 15 days 
after an order to begin final closure is issued by a U.S. district court 
or other court of competent jurisdiction; or
    (iii) Provide alternate financial assurance as specified in this 
section, and obtain the Regional Administrator's written approval of the 
assurance provided, within 90 days after receipt by both the owner or 
operator and the Regional Administrator of a notice of cancellation of 
the bond from the surety.
    (5) Under the terms of the bond, the surety will become liable on 
the bond obligation when the owner or operator fails to perform as 
guaranteed by the bond.
    (6) The penal sum of the bond must be in an amount at least equal to 
the current post-closure cost estimate, except as provided in 
Sec. 265.145(f).
    (7) Whenever the current post-closure cost estimate increases to an 
amount greater than the penal sum, the owner or operator, within 60 days 
after the increase, must either cause the penal sum to be increased to 
an amount at least equal to the current post-closure cost estimate and 
submit evidence of such increase to the Regional Administrator, or 
obtain other financial assurance as specified in this section to cover 
the increase. Whenever the current post-closure cost estimate decreases, 
the penal sum may be reduced to the amount of the current post-closure 
cost estimate following written approval by the Regional Administrator.
    (8) Under the terms of the bond, the surety may cancel the bond by 
sending

[[Page 417]]

notice of cancellation by certified mail to the owner or operator and to 
the Regional Administrator. Cancellation may not occur, however, during 
the 120 days beginning on the date of receipt of the notice of 
cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (9) The owner or operator may cancel the bond if the Regional 
Administrator has given prior written consent based on his receipt of 
evidence of alternate financial assurance as specified in this section.
    (c) Post-closure letter of credit. (1) An owner or operator may 
satisfy the requirements of this section by obtaining an irrevocable 
standby letter of credit which conforms to the requirements of this 
paragraph and submitting the letter to the Regional Administrator. The 
issuing institution must be an entity which has the authority to issue 
letters of credit and whose letter-of-credit operations are regulated 
and examined by a Federal or State agency.
    (2) The wording of the letter of credit must be identical to the 
wording specified in Sec. 264.151(d).
    (3) An owner or operator who uses a letter of credit to satisfy the 
requirements of this section must also establish a standby trust fund. 
Under the terms of the letter of credit, all amounts paid pursuant to a 
draft by the Regional Administrator will be deposited by the issuing 
institution directly into the standby trust fund in accordance with 
instructions from the Regional Administrator. This standby trust fund 
must meet the requirements of the trust fund specified in 
Sec. 265.145(a), except that:
    (i) An originally signed duplicate of the trust agreement must be 
submitted to the Regional Administrator with the letter of credit; and
    (ii) Unless the standby trust fund is funded pursuant to the 
requirements of this section, the following are not required by these 
regulations:
    (A) Payments into the trust fund as specified in Sec. 265.145(a);
    (B) Updating of Schedule A of the trust agreement (see 
Sec. 264.151(a)) to show current post-closure cost estimates;
    (C) Annual valuations as required by the trust agreement; and
    (D) Notices of nonpayment as required by the trust agreement.
    (4) The letter of credit must be accompanied by a letter from the 
owner or operator referring to the letter of credit by number, issuing 
institution, and date, and providing the following information: The EPA 
Identification Number, name, and address of the facility, and the amount 
of funds assured for post-closure care of the facility by the letter of 
credit.
    (5) The letter of credit must be irrevocable and issued for a period 
of at least 1 year. The letter of credit must provide that the 
expiration date will be automatically extended for a period of at least 
1 year unless, at least 120 days before the current expiration date, the 
issuing institution notifies both the owner or operator and the Regional 
Administrator by certified mail of a decision not to extend the 
expiration date. Under the terms of the letter of credit, the 120 days 
will begin on the date when both the owner or operator and the Regional 
Administrator have received the notice, as evidenced by the return 
receipts.
    (6) The letter of credit must be issued in an amount at least equal 
to the current post-closure cost estimate, except as provided in 
Sec. 265.145(f).
    (7) Whenever the current post-closure cost estimate increases to an 
amount greater than the amount of the credit during the operating life 
of the facility, the owner or operator, within 60 days after the 
increase, must either cause the amount of the credit to be increased so 
that it at least equals the current post-closure cost estimate and 
submit evidence of such increase to the Regional Administrator, or 
obtain other financial assurance as specified in this section to cover 
the increase. Whenever the current post-closure cost estimate decreases 
during the operating life of the facility, the amount of the credit may 
be reduced to the amount of the current post-closure cost estimate 
following written approval by the Regional Administrator.
    (8) During the period of post-closure care, the Regional 
Administrator may approve a decrease in the amount of

[[Page 418]]

the letter of credit if the owner or operator demonstrates to the 
Regional Administrator that the amount exceeds the remaining cost of 
post-closure care.
    (9) Following a final administrative determination pursuant to 
section 3008 of RCRA that the owner or operator has failed to perform 
post-closure care in accordance with the approved post-closure plan and 
other permit requirements, the Regional Administrator may draw on the 
letter of credit.
    (10) If the owner or operator does not establish alternate financial 
assurance as specified in this section and obtain written approval of 
such alternate assurance from the Regional Administrator within 90 days 
after receipt by both the owner or operator and the Regional 
Administrator of a notice from the issuing institution that it has 
decided not to extend the letter of credit beyond the current expiration 
date, the Regional Administrator will draw on the letter of credit. The 
Regional Administrator may delay the drawing if the issuing institution 
grants an extension of the term of the credit. During the last 30 days 
of any such extension the Regional Administrator will draw on the letter 
of credit if the owner or operator has failed to provide alternate 
financial assurance as specified in this section and obtain written 
approval of such assurance from the Regional Administrator.
    (11) The Regional Administrator will return the letter of credit to 
the issuing institution for termination when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 265.145(h).
    (d) Post-closure insurance. (1) An owner or operator may satisfy the 
requirements of this section by obtaining post-closure insurance which 
conforms to the requirements of this paragraph and submitting a 
certificate of such insurance to the Regional Administrator. By the 
effective date of these regulations the owner or operator must submit to 
the Regional Administrator a letter from an insurer stating that the 
insurer is considering issuance of post- closure insurance conforming to 
the requirements of this paragraph to the owner or operator. Within 90 
days after the effective date of these regulations, the owner or 
operator must submit the certificate of insurance to the Regional 
Administrator or establish other financial assurance as specified in 
this section. At a minimum, the insurer must be licensed to transact the 
business of insurance, or eligible to provide insurance as an excess or 
surplus lines insurer, in one or more States.
    (2) The wording of the certificate of insurance must be identical to 
the wording specified in Sec. 264.151(e).
    (3) The post-closure insurance policy must be issued for a face 
amount at least equal to the current post-closure cost estimate, except 
as provided in Sec. 265.145(f). The term ``face amount'' means the total 
amount the insurer is obligated to pay under the policy. Actual payments 
by the insurer will not change the face amount, although the insurer's 
future liability will be lowered by the amount of the payments.
    (4) The post-closure insurance policy must guarantee that funds will 
be available to provide post-closure care of the facility whenever the 
post-closure period begins. The policy must also guarantee that once 
post-closure care begins the insurer will be responsible for paying out 
funds, up to an amount equal to the face amount of the policy, upon the 
direction of the Regional Administrator, to such party or parties as the 
Regional Administrator specifies.
    (5) An owner or operator or any other person authorized to perform 
post-closure care may request reimbursement for post-closure care 
expenditures by submitting itemized bills to the Regional Administrator. 
Within 60 days after receiving bills for post-closure care activities, 
the Regional Administrator will instruct the insurer to make 
reimbursements in those amounts as the Regional Administrator specifies 
in writing, if the Regional Administrator determines that the post-
closure expenditures are in accordance with the approved post-closure 
plan or otherwise justified. If the

[[Page 419]]

Regional Administrator does not instruct the insurer to make such 
reimbursements, he will provide a detailed written statement of reasons.
    (6) The owner or operator must maintain the policy in full force and 
effect until the Regional Administrator consents to termination of the 
policy by the owner or operator as specified in paragraph (d)(11) of 
this section. Failure to pay the premium, without substitution of 
alternate financial assurance as specified in the section, will 
constitute a significant violation of these regulations, warranting such 
remedy as the Regional Administrator deems necessary. Such violation 
will be deemed to begin upon receipt by the Regional Administrator of a 
notice of future cancellation, termination, or failure to renew due to 
nonpayment of the premium, rather than upon the date of expiration.
    (7) Each policy most contain a provision allowing assignment of the 
policy to a successor owner or operator. Such assignment may be 
conditional upon consent of the insurer, provided such consent is not 
unreasonably refused.
    (8) The policy must provide that the insurer may not cancel, 
terminate, or fail to renew the policy except for failure to pay the 
premium. The automatic renewal of the policy must, at a minimum, provide 
the insured with the option of renewal at the face amount of the 
expiring policy. If there is a failure to pay the premium, the insurer 
may elect to cancel, terminate, or fail to renew the policy by sending 
notice by certified mail to the owner or operator and the Regional 
Administrator. Cancellation, termination, or failure to renew may not 
occur, however, during the 120 days beginning with the date of receipt 
of the notice by both the Regional Administrator and the owner or 
operator, as evidenced by the return receipts. Cancellation, 
termination, or failure to renew may not occur and the policy will 
remain in full force and effect in the event that on or before the date 
of expiration:
    (i) The Regional Administrator deems the facility abandoned; or
    (ii) Interim status is terminated or revoked; or
    (iii) Closure is ordered by the Regional Administrator or a U.S. 
district court or other court of competent jurisdiction; or
    (iv) The owner or operator is named as debtor in a voluntary or 
involuntary proceeding under Title 11 (Bankruptcy), U.S. Code; or
    (v) The premium due is paid.
    (9) Whenever the current post-closure cost estimate increases to an 
amount greater than the face amount of the policy during the operating 
life of the facility, the owner or operator, within 60 days after the 
increase, must either cause the face amount to be increased to an amount 
at least equal to the current post-closure cost estimate and submit 
evidence of such increase to the Regional Administrator, or obtain other 
financial assurance as specified in this section to cover the increase. 
Whenever the current post-closure cost estimate decreases during the 
operating life of the facility, the face amount may be reduced to the 
amount of the current post-closure cost estimate following written 
approval by the Regional Administrator.
    (10) Commencing on the date that liability to make payments pursuant 
to the policy accrues, the insurer will thereafter annually increase the 
face amount of the policy. Such increase must be equivalent to the face 
amounts of the policy, less any payments made, multiplied by an amount 
equivalent to 85 percent of the most recent investment rate or of the 
equivalent coupon-issue yield announced by the U.S. Treasury for 26-week 
Treasury securities.
    (11) The Regional Administrator will give written consent to the 
owner or operator that he may terminate the insurance policy when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 265.145(h).
    (e) Financial test and corporate guarantee for post-closure care. 
(1) An owner or operator may satisfy the requirements of this section by 
demonstrating that he passes a financial test as specified in this 
paragraph. To pass this test the owner or operator must meet the

[[Page 420]]

criteria either of paragraph (e)(1)(i) or (ii) of this section:
    (i) The owner or operator must have:
    (A) Two of the following three ratios: a ratio of total liabilities 
to net worth less than 2.0; a ratio of the sum of net income plus 
depreciation, depletion, and amortization to total liabilities greater 
than 0.1; and a ratio of current assets to current liabilities greater 
than 1.5; and
    (B) Net working capital and tangible net worth each at least six 
times the sum of the current closure and post-closure cost estimates and 
the current plugging and abandonment cost estimates; and
    (C) Tangible net worth of at least $10 million; and
    (D) Assets in the United States amounting to at least 90 percent of 
his total assets or at least six times the sum of the current closure 
and post-closure cost estimates and the current plugging and abandonment 
cost estimates.
    (ii) The owner or operator must have:
    (A) A current rating for his most recent bond issuance of AAA, AA, 
A, or BBB as issued by Standard and Poor's or Aaa, Aa, A, or Baa as 
issued by Moody's; and
    (B) Tangible net worth at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates; and
    (C) Tangible net worth of at least $10 million; and
    (D) Assets located in the United States amounting to at least 90 
percent of his total assets or at least six times the sum of the current 
closure and post-closure cost estimates and the current plugging and 
abandonment cost estimates.
    (2) The phrase ``current closure and post-closure cost estimates'' 
as used in paragraph (e)(1) of this section refers to the cost estimates 
required to be shown in paragraphs 1-4 of the letter from the owner's or 
operator's chief financial officer (Sec. 264.151(f)). The phrase 
``current plugging and abandonment cost estimates'' as used in paragraph 
(e)(1) of this section refers to the cost estimates required to be shown 
in paragraphs 1-4 of the letter from the owner's or operator's chief 
financial officer (Sec. 144.70(f) of this title).
    (3) To demonstrate that he meets this test, the owner or operator 
must submit the following items to the Regional Administrator:
    (i) A letter signed by the owner's or operator's chief financial 
officer and worded as specified in Sec. 264.151(f); and
    (ii) A copy of the independent certified public accountant's report 
on examination of the owner's or operator's financial statements for the 
latest completed fiscal year; and
    (iii) A special report from the owner's or operator's independent 
certified public accountant to the owner or operator stating that:
    (A) He has compared the data which the letter from the chief 
financial officer specifies as having been derived from the 
independently audited, year-end financial statements for the latest 
fiscal year with the amounts in such financial statements; and
    (B) In connection with that procedure, no matters came to his 
attention which caused him to believe that the specified data should be 
adjusted.
    (4) The owner or operator may obtain an extension of the time 
allowed for submission of the documents specified in paragraph (e)(3) of 
this section if the fiscal year of the owner or operator ends during the 
90 days prior to the effective date of these regulations and if the 
year-end financial statements for that fiscal year will be audited by an 
independent certified public accountant. The extension will end no later 
than 90 days after the end of the owner's or operator's fiscal year. To 
obtain the extension, the owner's or operator's chief financial officer 
must send, by the effective date of these regulations, a letter to the 
Regional Administrator of each Region in which the owner's or operator's 
facilities to be covered by the financial test are located. This letter 
from the chief financial officer must:
    (i) Request the extension;
    (ii) Certify that he has grounds to believe that the owner or 
operator meets the criteria of the financial test;
    (iii) Specify for each facility to be covered by the test the EPA 
Identification Number, name, address, and the

[[Page 421]]

current closure and post-closure cost estimates to be covered by the 
test;
    (iv) Specify the date ending the owner's or operator's latest 
complete fiscal year before the effective date of these regulations;
    (v) Specify the date, no later than 90 days after the end of such 
fiscal year, when he will submit the documents specified in paragraph 
(e)(3) of this section; and
    (vi) Certify that the year-end financial statements of the owner or 
operator for such fiscal year will be audited by an independent 
certified public accountant.
    (5) After the initial submission of items specified in paragraph 
(e)(3) of this section, the owner or operator must send updated 
information to the Regional Administrator within 90 days after the close 
of each succeeding fiscal year. This information must consist of all 
three items specified in paragraph (e)(3) of this section.
    (6) If the owner or operator no longer meets the requirements of 
paragraph (e)(1) of this section, he must send notice to the Regional 
Administrator of intent to establish alternate financial assurance as 
specified in this section. The notice must be sent by certified mail 
within 90 days after the end of the fiscal year for which the year-end 
financial data show that the owner or operator no longer meets the 
requirements. The owner or operator must provide the alternate financial 
assurance within 120 days after the end of such fiscal year.
    (7) The Regional Administrator may, based on a reasonable belief 
that the owner or operator may no longer meet the requirements of 
paragraph (e)(1) of this section, require reports of financial condition 
at any time from the owner or operator in addition to those specified in 
paragraph (e)(3) of this section. If the Regional Administrator finds, 
on the basis of such reports or other information, that the owner or 
operator no longer meets the requirements of paragraph (e)(1) of this 
section, the owner or operator must provide alternate financial 
assurance as specified in this section within 30 days after notification 
of such a finding.
    (8) The Regional Administrator may disallow use of this test on the 
basis of qualifications in the opinion expressed by the independent 
certified public accountant in his report on examination of the owner's 
or operator's financial statements (see paragraph (e)(3)(ii) of this 
section). An adverse opinion or a disclaimer of opinion will be cause 
for disallowance. The Regional Administrator will evaluate other 
qualifications on an individual basis. The owner or operator must 
provide alternate financial assurance as specified in this section 
within 30 days after notification of the disallowance.
    (9) During the period of post-closure care, the Regional 
Administrator may approve a decrease in the current post-closure cost 
estimate for which this test demonstrates financial assurance if the 
owner or operator demonstrates to the Regional Administrator that the 
amount of the cost estimate exceeds the remaining cost of post-closure 
care.
    (10) The owner or operator is no longer required to submit the items 
specified in paragraph (e)(3) of this section when:
    (i) An owner or operator substitutes alternate financial assurance 
as specified in this section; or
    (ii) The Regional Administrator releases the owner or operator from 
the requirements of this section in accordance with Sec. 265.145(h).
    (11) An owner or operator may meet the requirements for this section 
by obtaining a written guarantee. The guarantor must be the direct of 
higher-tier parent corporation of the owner or operator, a firm whose 
parent corporation is also the parent corporation of the owner or 
operator, or a firm with a ``substantial business relationship'' with 
the owner or operator. The guarantor must meet the requirements for 
owners or operators in paragraphs (f)(1) through (9) of this section and 
must comply with the terms of the guarantee. The wording of the 
guarantee must be identical to the wording specified in Sec. 264.151(h). 
A certified copy of the guarantee must accompany the items sent to the 
Regional Administrator as specified in paragraph (f)(3) of this section. 
One of these items must be the letter from the guarantor's chief 
financial officer. If the guarantor's parent

[[Page 422]]

corporation is also the parent corporation of the owner or operator, the 
letter must describe the value received in consideration of the 
guarantee. If the guarantor is a firm with a ``substantial business 
relationship'' with the owner or operator, this letter must describe 
this ``substantial business relationship'' and the value received in 
consideration of the guarantee. The terms of the guarantee must provide 
that:
    (i) If the owner or operator fails to perform post-closure care of a 
facility covered by the corporate guarantee in accordance with the post-
closure plan and other interim status requirements whenever required to 
do so, the guarantor will do so or establish a trust fund as specified 
in Sec. 265.145(a) in the name of the owner or operator.
    (ii) The corporate guarantee will remain in force unless the 
guarantor sends notice of cancellation by certified mail to the owner or 
operator and to the Regional Administrator. Cancellation may not occur, 
however, during the 120 days beginning on the date of receipt of the 
notice of cancellation by both the owner or operator and the Regional 
Administrator, as evidenced by the return receipts.
    (iii) If the owner or operator fails to provide alternate financial 
assurance as specified in this section and obtain the written approval 
of such alternate assurance from the Regional Administrator within 90 
days after receipt by both the owner or operator and the Regional 
Administrator of a notice of cancellation of the corporate guarantee 
from the guarantor, the guarantor will provide such alternate financial 
assurance in the name of the owner or operator.
    (f) Use of multiple financial mechanisms. An owner or operator may 
satisfy the requirements of this section by establishing more than one 
financial mechanism per facility. These mechanisms are limited to trust 
funds, surety bonds, letters of credit, and insurance. The mechanisms 
must be as specified in paragraphs (a) through (d), respectively, of 
this section, except that it is the combination of mechanisms, rather 
than the single mechanism, which must provide financial assurance for an 
amount at least equal to the current post-closure cost estimate. If an 
owner or operator uses a trust fund in combination with a surety bond or 
a letter of credit, he may use the trust fund as the standby trust fund 
for the other mechanisms. A single standby trust fund may be established 
for two or more mechanisms. The Regional Administrator may use any or 
all of the mechanisms to provide for post-closure care of the facility.
    (g) Use of a financial mechanism for multiple facilities. An owner 
or operator may use a financial assurance mechanism specified in this 
section to meet the requirements of this section for more than one 
facility. Evidence of financial assurance submitted to the Regional 
Administrator must include a list showing, for each facility, the EPA 
Identification Number, name, address, and the amount of funds for post-
closure care assured by the mechanism. If the facilities covered by the 
mechanism are in more than one Region, identical evidence of financial 
assurance must be submitted to and maintained with the Regional 
Administrators of all such Regions. The amount of funds available 
through the mechanism must be no less than the sum of funds that would 
be available if a separate mechanism had been established and maintained 
for each facility. In directing funds available through the mechanism 
for post-closure care of any of the facilities covered by the mechanism, 
the Regional Administrator may direct only the amount of funds 
designated for that facility, unless the owner or operator agrees to the 
use of additional funds available under the mechanism.
    (h) Release of the owner or operator from the requirements of this 
section. Within 60 days after receiving certifications from the owner or 
operator and an independent registered professional engineer that the 
post-closure care period has been completed in accordance with the 
approved post-closure plan, the Regional Administrator will notify the 
owner or operator in writing that he is no longer required by this 
section to maintain financial assurance for post-closure care of that 
unit, unless the Regional Administrator has reason to believe that post-
closure care has not been in accordance with the approved post-closure 
plan. The Regional Administrator will provide the owner

[[Page 423]]

or operator a detailed written statement of any such reason to believe 
that post-closure care has not been in accordance with the approved 
post-closure plan.

FR 42843, Sept. 16, 1992]



Sec. 265.146  Use of a mechanism for financial assurance of both closure and post-closure care.

    An owner or operator may satisfy the requirements for financial 
assurance for both closure and post-closure care for one or more 
facilities by using a trust fund, surety bond, letter of credit, 
insurance, financial test, or corporate guarantee that meets the 
specifications for the mechanism in both Secs. 265.143 and 265.145. The 
amount of funds available through the mechanism must be no less than the 
sum of funds that would be available if a separate mechanism had been 
established and maintained for financial assurance of closure and of 
post-closure care.



Sec. 265.147  Liability requirements.

    (a) Coverage for sudden accidental occurrences. An owner or operator 
of a hazardous waste treatment, storage, or disposal facility, or a 
group of such facilities, must demonstrate financial responsibility for 
bodily injury and property damage to third parties caused by sudden 
accidental occurrences arising from operations of the facility or group 
of facilities. The owner or operator must have and maintain liability 
coverage for sudden accidental occurrences in the amount of at least $1 
million per occurrence with an annual aggregate of at least $2 million, 
exclusive of legal defense costs. This liability coverage may be 
demonstrated as specified in paragraphs (a) (1), (2), (3), (4), (5), or 
(6) of this section:
    (1) An owner or operator may demonstrate the required liability 
coverage by having liability insurance as specified in this paragraph.
    (i) Each insurance policy must be amended by attachment of the 
Hazardous Waste Facility Liability Endorsement, or evidenced by a 
Certificate of Liability Insurance. The wording of the endorsement must 
be identical to the wording specified in Sec. 264.151(i). The wording of 
the certificate of insurance must be identical to the wording specified 
in Sec. 264.151(j). The owner or operator must submit a signed duplicate 
original of the endorsement or the certificate of insurance to the 
Regional Administrator, or Regional Administrator if facilities are 
located in more than one Region. If requested by a Regional 
Administrator, the owner or operator must provide a signed duplicate 
original of the insurance policy.
    (ii) Each insurance policy must be issued by an insurer which, at a 
minimum, is licensed to transact the business of insurance, or eligible 
to provide insurance as an excess or surplus lines insurer, in one or 
more States.
    (2) An owner or operator may meet the requirements of this section 
by passing a financial test or using the guarantee for liability 
coverage as specified in paragraphs (f) and (g) of this section.
    (3) An owner or operator may meet the requirements of this section 
by obtaining a letter of credit for liability coverage as specified in 
paragraph (h) of this section.
    (4) An owner or operator may meet the requirements of this section 
by obtaining a surety bond for liability coverage as specified in 
paragraph (i) of this section.
    (5) An owner or operator may meet the requirements of this section 
by obtaining a trust fund for liability coverage as specified in 
paragraph (j) of this section.
    (6) An owner or operator may demonstrate the required liability 
coverage through the use of combinations of insurance, financial test, 
guarantee, letter of credit, surety bond, and trust fund, except that 
the owner or operator may not combine a financial test covering part of 
the liability coverage requirement with a guarantee unless the financial 
statement of the owner or operator is not consolidated with the 
financial statement of the guarantor. The amounts of coverage 
demonstrated must total at least the minimum amounts required by this 
section. If the owner or operator demonstrates the required coverage 
through the use of a combination of financial assurances under this 
paragraph, the owner

[[Page 424]]

or operator shall specify at least one such assurance as ``primary'' 
coverage and shall specify other assurance as ``excess'' coverage.
    (7) An owner or operator shall notify the Regional Administrator in 
writing within 30 days whenever:
    (i) A claim results in a reduction in the amount of financial 
assurance for liability coverage provided by a financial instrument 
authorized in paragraphs (a)(1) through (a)(6) of this section; or
    (ii) A Certification of Valid Claim for bodily injury or property 
damages caused by a sudden or non-sudden accidental occurrence arising 
from the operation of a hazardous waste treatment, storage, or disposal 
facility is entered between the owner or operator and third-party 
claimant for liability coverage under paragraphs (a)(1) through (a)(6) 
of this section; or
    (iii) A final court order establishing a judgment for bodily injury 
or property damage caused by a sudden or non-sudden accidental 
occurrence arising from the operation of a hazardous waste treatment, 
storage, or disposal facility is issued against the owner or operator or 
an instrument that is providing financial assurance for liability 
coverage under paragraphs (a)(1) through (a)(6) of this section.
    (b) Coverage for nonsudden accidental occurrences. An owner or 
operator of a surface impoundment, landfill, or land treatment facility 
which is used to manage hazardous waste, or a group of such facilities, 
must demonstrate financial responsibility for bodily injury and property 
damage to third parties caused by nonsudden accidental occurrences 
arising from operations of the facility or group of facilities. The 
owner or operator must have and maintain liability coverage for 
nonsudden accidental occurrences in the amount of at least $3 million 
per occurrence with an annual aggregate of at least $6 million, 
exclusive of legal defense costs. An owner or operator who must meet the 
requirements of this section may combine the required per-occurrence 
coverage levels for sudden and nonsudden accidental occurrences into a 
single per-occurrence level, and combine the required annual aggregate 
coverage levels for sudden and nonsudden accidental occurrences into a 
single annual aggregate level. Owners or operators who combine coverage 
levels for sudden and nonsudden accidental occurrences must maintain 
liability coverage in the amount of at least $4 million per occurrence 
and $8 million annual aggregate. This liability coverage may be 
demonstrated as specified in paragraph (b) (1), (2), (3), (4), (5), or 
(6) of this section:
    (1) An owner or operator may demonstrate the required liability 
coverage by having liability insurance as specified in this paragraph.
    (2) An owner or operator may meet the requirements of this section 
by passing a financial test or using the guarantee for liability 
coverage as specified in paragraphs (f) and (g) of this section.
    (3) An owner or operator may meet the requirements of this section 
by obtaining a letter of credit for liability coverage as specified in 
paragraph (h) of this section.
    (4) An owner or operator may meet the requirements of this section 
by obtaining a surety bond for liability coverage as specified in 
paragraph (i) of this section.
    (5) An owner or operator may meet the requirements of this section 
by obtaining a trust fund for liability coverage as specified in 
paragraph (j) of this section.
    (6) An owner or operator may demonstrate the required liability 
coverage through the use of combinations of insurance, financial test, 
guarantee, letter of credit, surety bond, and trust fund, except that 
the owner or operator may not combine a financial test covering part of 
the liability coverage requirement with a guarantee unless the financial 
statement of the owner or operator is not consolidated with the 
financial statement of the guarantor. The amounts of coverage 
demonstrated must total at least the minimum amounts required by this 
section. If the owner or operator demonstrates the required coverage 
through the use of a combination of financial assurances under this 
paragraph, the owner or operator shall specify at least one such 
assurance as ``primary'' coverage and shall specify other assurance as 
``excess'' coverage.

[[Page 425]]

    (7) An owner or operator shall notify the Regional Administrator in 
writing within 30 days whenever:
    (i) A claim results in a reduction in the amount of financial 
assurance for liability coverage provided by a financial instrument 
authorized in paragraphs (b)(1) through (b)(6) of this section; or
    (ii) A Certification of Valid Claim for bodily injury or property 
damages caused by a sudden or non-sudden accidental occurrence arising 
from the operation of a hazardous waste treatment, storage, or disposal 
facility is entered between the owner or operator and third-party 
claimant for liability coverage under paragraphs (b)(1) through (b)(6) 
of this section; or
    (iii) A final court order establishing a judgment for bodily injury 
or property damage caused by a sudden or non-sudden accidental 
occurrence arising from the operation of a hazardous waste treatment, 
storage, or disposal facility is issued against the owner or operator or 
an instrument that is providing financial assurance for liability 
coverage under paragraphs (b)(1) through (b)(6) of this section.
    (c) Request for variance. If an owner or operator can demonstrate to 
the satisfaction of the Regional Administrator that the levels of 
financial responsibility required by paragraph (a) or (b) of this 
section are not consistent with the degree and duration of risk 
associated with treatment, storage, or disposal at the facility or group 
of facilities, the owner or operator may obtain a variance from the 
Regional Administrator. The request for a variance must be submitted in 
writing to the Regional Administrator. If granted, the variance will 
take the form of an adjusted level of required liability coverage, such 
level to be based on the Regional Administrator's assessment of the 
degree and duration of risk associated with the ownership or operation 
of the facility or group of facilities. The Regional Administrator may 
require an owner or operator who requests a variance to provide such 
technical and engineering information as is deemed necessary by the 
Regional Administrator to determine a level of financial responsibility 
other than that required by paragraph (a) or (b) of this section. The 
Regional Administrator will process a variance request as if it were a 
permit modification request under Sec. 270.41(a)(5) of this chapter and 
subject to the procedures of Sec. 124.5 of this chapter. Notwithstanding 
any other provision, the Regional Administrator may hold a public 
hearing at his discretion or whenever he finds, on the basis of requests 
for a public hearing, a significant degree of pubic interest in a 
tentative decision to grant a variance.
    (d) Adjustments by the Regional Administrator. If the Regional 
Administrator determines that the levels of financial responsibility 
required by paragraph (a) or (b) of this section are not consistent with 
the degree and duration of risk associated with treatment, storage, or 
disposal at the facility or group of facilities, the Regional 
Administrator may adjust the level of financial responsibility required 
under paragraph (a) or (b) of this section as may be necessary to 
protect human health and the environment. This adjusted level will be 
based on the Regional Administrator's assessment of the degree and 
duration of risk associated with the ownership or operation of the 
facility or group of facilities. In addition, if the Regional 
Administrator determines that there is a significant risk to human 
health and the environment from nonsudden accidental occurrences 
resulting from the operations of a facility that is not a surface 
impoundment, landfill, or land treatment facility, he may require that 
an owner or operator of the facility comply with paragraph (b) of this 
section. An owner or operator must furnish to the Regional 
Administrator, within a reasonable time, any information which the 
Regional Administrator requests to determine whether cause exists for 
such adjustments of level or type of coverage. The Regional 
Administrator will process an adjustment of the level of required 
coverage as if it were a permit modification under Sec. 270.41(a)(5) of 
this chapter and subject to the procedures of Sec. 124.5 of this 
chapter. Notwithstanding any other provision, the Regional Administrator 
may hold a public hearing at his discretion or whenever he finds, on the 
basis of requests for a public hearing, a significant degree of public 
interest in a tentative decision

[[Page 426]]

to adjust the level or type of required coverage.
    (e) Period of coverage. Within 60 days after receiving 
certifications from the owner or operator and an independent registered 
professional engineer that final closure has been completed in 
accordance with the approved closure plan, the Regional Administrator 
will notify the owner or operator in writing that he is no longer 
required by this section to maintain liability coverage for that 
facility, unless the Regional Administrator has reason to believe that 
closure has not been in accordance with the approved closure plan.
    (f) Financial test for liability coverage. (1) An owner or operator 
may satisfy the requirements of this section by demonstrating that he 
passes a financial test as specified in this paragraph. To pass this 
test the owner or operator must meet the criteria of paragraph (f)(1) 
(i) or (ii) of this section:
    (i) The owner or operator must have:
    (A) Net working capital and tangible net worth each at least six 
times the amount of liability coverage to be demonstrated by this test; 
and
    (B) Tangible net worth of at least $10 million; and
    (C) Assets in the United States amounting to either: (1) At least 90 
percent of his total assets; or (2) at least six times the amount of 
liability coverage to be demonstrated by this test.
    (ii) The owner or operator must have:
    (A) A current rating for his most recent bond issuance of AAA, AA, 
A, or BBB as issued by Standard and Poor's, or Aaa, Aa, A, or Baa as 
issued by Moody's; and
    (B) Tangible net worth of at least $10 million; and
    (C) Tangible net worth at least six times the amount of liability 
coverage to be demonstrated by this test; and
    (D) Assets in the United States amounting to either: (1) At least 90 
percent of his total assets; or (2) at least six times the amount of 
liability coverage to be demonstrated by this test.
    (2) The phrase ``amount of liability coverage'' as used in paragraph 
(f)(1) of this section refers to the annual aggregate amounts for which 
coverage is required under paragraphs (a) and (b) of this section.
    (3) To demonstrate that he meets this test, the owner or operator 
must submit the following three items to the Regional Administrator:
    (i) A letter signed by the owner's or operator's chief financial 
officer and worded as specified in Sec. 264.151(g). If an owner or 
operator is using the financial test to demonstrate both assurance for 
closure or post-closure care, as specified by Secs. 264.143(f), 
264.145(f), 265.143(e), and 265.145(e), and liability coverage, he must 
submit the letter specified in Sec. 264.151(g) to cover both forms of 
financial responsibility; a separate letter as specified in 
Sec. 264.151(f) is not required.
    (ii) A copy of the independent certified public accountant's report 
on examination of the owner's or operator's financial statements for the 
latest completed fiscal year.
    (iii) A special report from the owner's or operator's independent 
certified public accountant to the owner or operator stating that:
    (A) He has compared the data which the letter from the chief 
financial officer specifies as having been derived from the 
independently audited, year-end financial statements for the latest 
fiscal year with the amounts in such financial statements; and
    (B) In connection with that procedure, no matters came to his 
attention which caused him to believe that the specified data should be 
adjusted.
    (4) The owner or operator may obtain a one-time extension of the 
time allowed for submission of the documents specified in paragraph 
(f)(3) of this section if the fiscal year of the owner or operator ends 
during the 90 days prior to the effective date of these regulations and 
if the year-end financial statements for that fiscal year will be 
audited by an independent certified public accountant. The extension 
will end no later than 90 days after the end of the owner's or 
operator's fiscal year. To obtain the extension, the owner's or 
operator's chief financial officer must send, by the effective date of 
these regulations, a letter to the Regional Administrator of each Region 
in which the owner's or operator's facilities to be covered by the 
financial test are located. This letter from the chief financial officer 
must:
    (i) Request the extension;

[[Page 427]]

    (ii) Certify that he has grounds to believe that the owner or 
operator meets the criteria of the financial test;
    (iii) Specify for each facility to be covered by the test the EPA 
Identification Number, name, address, the amount of liability coverage 
and, when applicable, current closure and post-closure cost estimates to 
be covered by the test;
    (iv) Specify the date ending the owner's or operator's last complete 
fiscal year before the effective date of these regulations;
    (v) Specify the date, no later than 90 days after the end of such 
fiscal year, when he will submit the documents specified in paragraph 
(f)(3) of this section; and
    (vi) Certify that the year-end financial statements of the owner or 
operator for such fiscal year will be audited by an independent 
certified public accountant.
    (5) After the initial submission of items specified in paragraph 
(f)(3) of this section, the owner or operator must send updated 
information to the Regional Administrator within 90 days after the close 
of each succeeding fiscal year. This information must consist of all 
three items specified in paragraph (f)(3) of this section.
    (6) If the owner or operator no longer meets the requirements of 
paragraph (f)(1) of this section, he must obtain insurance, a letter of 
credit, a surety bond, a trust fund, or a guarantee for the entire 
amount of required liability coverage as specified in this section. 
Evidence of liability coverage must be submitted to the Regional 
Administrator within 90 days after the end of the fiscal year for which 
the year-end financial data show that the owner or operator no longer 
meets the test requirements.
    (7) The Regional Administrator may disallow use of this test on the 
basis of qualifications in the opinion expressed by the independent 
certified public accountant in his report on examination of the owner's 
or operator's financial statements (see paragraph (f)(3)(ii) of this 
section). An adverse opinion or a disclaimer of opinion will be cause 
for disallowance. The Regional Administrator will evaluate other 
qualifications on an individual basis. The owner or operator must 
provide evidence of insurance for the entire amount of required 
liability coverage as specified in this section within 30 days after 
notification of disallowance.
    (g) Guarantee for liability coverage. (1) Subject to paragraph 
(g)(2) of this section, an owner or operator may meet the requirements 
of this section by obtaining a written guarantee, hereinafter referred 
to as ``guarantee.'' The guarantor must be the direct or higher-tier 
parent corporation of the owner or operator, a firm whose parent 
corporation is also the parent corporation of the owner or operator, or 
a firm with a ``substantial business relationship'' with the owner or 
operator. The guarantor must meet the requirements for owners or 
operators in paragraphs (f)(1) through (f)(6) of this section. The 
wording of the guarantee must be identical to the wording specified in 
Sec. 264.151(h)(2) of this chapter. A certified copy of the guarantee 
must accompany the items sent to the Regional Administrator as specified 
in paragraph (f)(3) of this section. One of these items must be the 
letter from the guarantor's chief financial officer. If the guarantor's 
parent corporation is also the parent corporation of the owner or 
operator, this letter must describe the value received in consideration 
of the guarantee. If the guarantor is a firm with a ``substantial 
business relationship'' with the owner or operator, this letter must 
describe this ``substantial business relationship'' and the value 
received in consideration of the guarantee.
    (i) If the owner or operator fails to satisfy a judgment based on a 
determination of liability for bodily injury or property damage to third 
parties caused by sudden or nonsudden accidental occurrences (or both as 
the case may be), arising from the operation of facilities covered by 
this corporate guarantee, or fails to pay an amount agreed to in 
settlement of claims arising from or alleged to arise from such injury 
or damage, the guarantor will do so up to the limits of coverage.
    (ii) [Reserved]
    (2)(i) In the case of corporations incorporated in the United 
States, a guarantee may be used to satisfy the requirements of this 
section only if the

[[Page 428]]

Attorneys General or Insurance Commissioners of (A) the State in which 
the guarantor is incorporated, and (B) each State in which a facility 
covered by the guarantee is located have submitted a written statement 
to EPA that a guarantee executed as described in this section and 
Sec. 264.151(h)(2) is a legally valid and enforceable obligation in that 
State.
    (ii) In the case of corporations incorporated outside the United 
States, a guarantee may be used to satisfy the requirements of this 
section only if (A) the non-U.S. corporation has identified a registered 
agent for service of process in each State in which a facility covered 
by the guarantee is located and in the State in which it has its 
principal place of business, and if (B) the Attorney General or 
Insurance Commissioner of each State in which a facility covered by the 
guarantee is located and the State in which the guarantor corporation 
has its principal place of business, has submitted a written statement 
to EPA that a guarantee executed as described in this section and 
Sec. 264.151(h)(2) is a legally valid and enforceable obligation in that 
State.
    (h) Letter of credit for liability coverage. (1) An owner or 
operator may satisfy the requirements of this section by obtaining an 
irrevocable standby letter of credit that conforms to the requirements 
of this paragraph and submitting a copy of the letter of credit to the 
Regional Administrator.
    (2) The financial institution issuing the letter of credit must be 
an entity that has the authority to issue letters of credit and whose 
letter of credit operations are regulated and examined by a Federal or 
State agency.
    (3) The wording of the letter of credit must be identical to the 
wording specified in Sec. 264.151(k) of this chapter.
    (4) An owner or operator who uses a letter of credit to satisfy the 
requirements of this section may also establish a standby trust fund. 
Under the terms of such a letter of credit, all amounts paid pursuant to 
a draft by the trustee of the standby trust will be deposited by the 
issuing institution into the standby trust in accordance with 
instructions from the trustee. The trustee of the standby trust fund 
must be an entity which has the authority to act as a trustee and whose 
trust operations are regulated and examined by a Federal or State 
agency.
    (5) The wording of the standby trust fund must be identical to the 
wording specified in Sec. 264.151(n).
    (i) Surety bond for liability coverage. (1) An owner or operator may 
satisfy the requirements of this section by obtaining a surety bond that 
conforms to the requirements of this paragraph and submitting a copy of 
the bond to the Regional Administrator.
    (2) The surety company issuing the bond must be among those listed 
as acceptable sureties on Federal bonds in the most recent Circular 570 
of the U.S. Department of the Treasury.
    (3) The wording of the surety bond must be identical to the wording 
specified in Sec. 264.151(l) of this chapter.
    (4) A surety bond may be used to satisfy the requirements of this 
section only if the Attorneys General or Insurance Commissioners of (i) 
the State in which the surety is incorporated, and (ii) each State in 
which a facility covered by the surety bond is located have submitted a 
written statement to EPA that a surety bond executed as described in 
this section and Sec. 264.151(l) of this chapter is a legally valid and 
enforceable obligation in that State.
    (j) Trust fund for liability coverage. (1) An owner or operator may 
satisfy the requirements of this section by establishing a trust fund 
that conforms to the requirements of this paragraph and submitting an

a trustee and whose trust operations are regulated and examined by a 
Federal or State agency.
    (3) The trust fund for liability coverage must be funded for the 
full amount of the liability coverage to be provided by the trust fund 
before it may be relied upon to satisfy the requirements of this 
section. If at any time after the trust fund is created the amount of 
funds in the trust fund is reduced below the full amount of the 
liability coverage to be provided, the owner or operator, by the 
anniversary date of the establishment of the Fund, must either add 
sufficient funds to the

[[Page 429]]

trust fund to cause its value to equal the full amount of liability 
coverage to be provided, or obtain other financial assurance as 
specified in this section to cover the difference. For purposes of this 
paragraph, ``the full amount of the liability coverage to be provided'' 
means the amount of coverage for sudden and/or nonsudden occurrences 
required to be provided by the owner or operator by this section, less 
the amount of financial assurance for liability coverage that is being 
provided by other financial assurance mechanisms being used to 
demonstrate financial assurance by the owner or operator.
    (4) The wording of the trust fund must be identical to the wording 
specified in Sec. 264.151(m) of this part.
    (k) Notwithstanding any other provision of this part, an owner or 
operator using liability insurance to satisfy the requirements of this 
section may use, until October 16, 1982, a Hazardous Waste Facility 
Liability Endorsement or Certificate of Liability Insurance that does 
not certify that the insurer is licensed to transact the business of 
insurance, or eligible as an excess or surplus lines insurer, in one or 
more States.

Sec. 265.148  Incapacity of owners or operators, guarantors, or financial institutions.

    (a) An owner or operator must notify the Regional Administrator by 
certified mail of the commencement of a voluntary or involuntary 
proceeding under Title 11 (Bankruptcy), U.S. Code, naming the owner or 
operator as debtor, within 10 days after commencement of the proceeding. 
A guarantor of a corporate guarantee as specified in Secs. 265.143(e) 
and 265.145(e) must make such a notification if he is named as debtor, 
as required under the terms of the corporate guarantee 
(Sec. 264.151(h)).
    (b) An owner or operator who fulfills the requirements of 
Sec. 265.143, Sec. 265.145, or Sec. 265.147 by obtaining a trust fund, 
surety bond, letter of credit, or insurance policy will be deemed to be 
without the required financial assurance or liability coverage in the 
event of bankruptcy of the trustee or issuing institution, or a 
suspension or revocation of the authority of the trustee institution to 
act as trustee or of the institution issuing the surety bond, letter of 
credit, or insurance policy to issue such instruments. The owner or 
operator must establish other financial assurance or liability coverage 
within 60 days after such an event.



Sec. 265.149  Use of State-required mechanisms.

    (a) For a facility located in a State where EPA is administering the 
requirements of this subpart but where the State has hazardous waste 
regulations that include requirements for financial assurance of closure 
or post-closure care or liability coverage, an owner or operator may use 
State-required financial mechanisms to meet the requirements of 
Sec. 265.143, Sec. 265.145, or Sec. 265.147 if the Regional 
Administrator determines that the State mechanisms are at least 
equivalent to the financial mechanisms specified in this subpart. The 
Regional Administrator will evaluate the equivalency of the mechanisms 
principally in terms of (1) certainty of the availability of funds for 
the required closure or post-closure care activities or liability 
coverage and (2) the amount of funds that will be made available. The 
Regional Administrator may also consider other factors as he deems 
appropriate. The owner or operator must submit to the Regional 
Administrator evidence of the establishment of the mechanism together 
with a letter requesting that the State-required mechanism be considered 
acceptable for meeting the requirements of this subpart. The submission 
must include the following information: The facility's EPA 
Identification Number, name, and address, and the amount of funds for 
closure or post-closure care or liability coverage assured by the 
mechanism. The Regional Administrator will notify the owner or operator 
of his determination regarding the mechanism's acceptability in lieu of 
financial mechanisms specified in this subpart. The Regional 
Administrator

[[Page 430]]

may require the owner or operator to submit additional information as is 
deemed necessary to make this determination. Pending this determination, 
the owner or operator will be deemed to be in compliance with the 
requirements of Sec. 265.143, Sec. 265.145, or Sec. 265.147, as 
applicable.
    (b) If a State-required mechanism is found acceptable as specified 
in paragraph (a) of this section except for the amount of funds 
available, the owner or operator may satisfy the requirements of this 
subpart by increasing the funds available through the State-required 
mechanism or using additional financial mechanisms as specified in this 
subpart. The amount of funds available through the State and Federal 
mechanisms must at least equal the amount required by this subpart.



Sec. 265.150  State assumption of responsibility.

    (a) If a State either assumes legal responsibility for an owner's or 
operator's compliance with the closure, post-closure care, or liability 
requirements of this part or assures that funds will be available from 
State sources to cover those requirements, the owner or operator will be 
in compliance with the requirements of Sec. 265.143, Sec. 265.145, or 
Sec. 265.147 if the Regional Administrator determines that the State's 
assumption of responsibility is at least equivalent to the financial 
mechanisms specified in this subpart. The Regional Administrator will 
evaluate the equivalency of State guarantees principally in terms of (1) 
certainty of the availability of funds for the required closure or post-
closure care activities or liability coverage and (2) the amount of 
funds that will be made available. The Regional Administrator may also 
consider other factors as he deems appropriate. The owner or operator 
must submit to the Regional Administrator a letter from the State 
describing the nature of the State's assumption of responsibility 
together with a letter from the owner or operator requesting that the 
State's assumption of responsibility be considered acceptable for 
meeting the requirements of this subpart. The letter from the State must 
include, or have attached to it, the following information: The 
facility's EPA Identification Number, name, and address, and the amount 
of funds for closure or post-closure care or liability coverage that are 
guaranteed by the State. The Regional Administrator will notify the 
owner or operator of his determination regarding the acceptability of 
the State's guarantee in lieu of financial mechanisms specified in this 
subpart. The Regional Administrator may require the owner or operator to 
submit additional information as is deemed necessary to make this 
determination. Pending this determination, the owner or operator will be 
deemed to be in compliance with the requirements of Secs. 265.143, 
Sec. 265.145, or Sec. 265.147, as applicable.
    (b) If a State's assumption of responsibility is found acceptable as 
specified in paragraph (a) of this section except for the amount of 
funds available, the owner or operator may satisfy the requirements of 
this subpart by use of both the State's assurance and additional 
financial mechanisms as specified in this subpart. The amount of funds 
available through the State and Federal mechanisms must at least equal 
the amount required by this subpart.



               Subpart I--Use and Management of Containers



Sec. 265.170  Applicability.

    The regulations in this subpart apply to owners and operators of all 
hazardous waste facilities that store containers of hazardous waste, 
except as Sec. 265.1 provides otherwise.



Sec. 265.171  Condition of containers.

    If a container holding hazardous waste is not in good condition, or 
if it begins to leak, the owner or operator must transfer the hazardous 
waste from this container to a container that is in good condition, or 
manage the waste in some other way that complies with the requirements 
of this part.



Sec. 265.172  Compatibility of waste with container.

    The owner or operator must use a container made of or lined with 
materials which will not react with, and are

[[Page 431]]

otherwise compatible with, the hazardous waste to be stored, so that the 
ability of the container to contain the waste is not impaired.



Sec. 265.173  Management of containers.

    (a) A container holding hazardous waste must always be closed during 
storage, except when it is necessary to add or remove waste.
    (b) A container holding hazardous waste must not be opened, handled, 
or stored in a manner which may rupture the container or cause it to 
leak.

[Comment: Re-use of containers in transportation is governed by U.S. 
Department of Transportation regulations, including those set forth in 
49 CFR 173.28.]

[45 FR 33232, May 19, 1980, as amended at 45 FR 78529, Nov. 25, 1980]



Sec. 265.174  Inspections.

    The owner or operator must inspect areas where containers are 
stored, at least weekly, looking for leaks and for deterioration caused

55 FR 50486, Dec. 6, 1990; 58 FR 46050, Aug. 31, 1993]



Sec. 265.191  Assessment of existing tank system's integrity.

    (a) For each existing tank system that does not have secondary 
containment meeting the requirements of Sec. 265.193, the owner or 
operator must determine that the tank system is not leaking or is unfit 
for use. Except as provided in paragraph (c) of this section, the owner 
or operator must obtain and keep on file at the facility a written 
assessment reviewed and certified by an independent, qualified, 
registered professional engineer in accordance with Sec. 270.11(d), that 
attests to the tank system's integrity by January 12, 1988.
    (b) This assessment must determine that the tank system is 
adequately designed and has sufficient structural strength and 
compatibility with the waste(s) to be stored or treated to ensure that 
it will not collapse, rupture, or fail. At a minimum, this assessment 
must consider the following:
    (1) Design standard(s), if available, according to which the tank 
and ancillary equipment were constructed;
    (2) Hazardous characteristics of the waste(s) that have been or will 
be handled;
    (3) Existing corrosion protection measures;
    (4) Documented age of the tank system, if available, (otherwise, an 
estimate of the age); and
    (5) Results of a leak test, internal inspection, or other tank 
integrity examination such that:
    (i) For non-enterable underground tanks, this assessment must 
consist of a leak test that is capable of taking into account the 
effects of temperature variations, tank end deflection, vapor pockets, 
and high water table effects,
    (ii) For other than non-enterable underground tanks and for 
ancillary equipment, this assessment must be either a leak test, as 
described above, or an internal inspection and/or other tank integrity 
examination certified by an independent, qualified, registered 
professional engineer in accordance with Sec. 270.11(d) that addresses 
cracks, leaks, corrosion, and erosion.

    [Note: The practices described in the American Petroleum Institute 
(API) Publication, Guide for Inspection of Refinery Equipment, Chapter 
XIII, ``Atmospheric and Low-Pressure Storage Tanks,'' 4th edition, 1981, 
may be used, where applicable, as guidelines in conducting the integrity 
examination of an other than non-enterable underground tank system.]

    (c) Tank systems that store or treat materials that become hazardous 
wastes subsequent to July 14, 1986 must conduct this assessment within 
12 months after the date that the waste becomes a hazardous waste.
    (d) If, as a result of the assessment conducted in accordance with 
paragraph (a) of this section, a tank system is found to be leaking or 
unfit for use, the owner or operator must comply with the requirements 
of Sec. 265.196.



Sec. 265.192  Design and installation of new tank systems or components.

    (a) Owners or operators of new tank systems or components must 
ensure that the foundation, structural support, seams, connections, and 
pressure controls (if applicable) are adequately designed and that the 
tank system has sufficient structural strength, compatibility with the 
waste(s) to be stored or treated, and corrosion protection so that it 
will not collapse, rupture, or fail. The owner or operator must obtain a 
written assessment reviewed and certified by an independent, qualified, 
registered professional engineer in accordance with Sec. 270.11(d) 
attesting that the system has sufficient structural integrity and is 
acceptable for the storing and treating of hazardous waste. This 
assessment must include, at a minimum, the following information:
    (1) Design standard(s) according to which the tank(s) and ancillary 
equipment is or will be constructed.
    (2) Hazardous characteristics of the waste(s) to be handled.
    (3) For new tank systems or components in which the external shell 
of a metal tank or any external metal component of the tank system is or 
will be in contact with the soil or with water, a determination by a 
corrosion expert of:

[[Page 433]]

    (i) Factors affecting the potential for corrosion, including but not 
limited to:
    (A) Soil moisture content;
    (B) Soil pH;
    (C) Soil sulfides level;
    (D) Soil resistivity;
    (E) Structure to soil potential;
    (F) Influence of nearby underground metal structures (e.g., piping);
    (G) Stray electric current; and,
    (H) Existing corrosion-protection measures (e.g., coating, cathodic 
protection), and
    (ii) The type and degree of external corrosion protection that are 
needed to ensure the integrity of the tank system during the use of the 
tank system or component, consisting of one or more of the following:
    (A) Corrosion-resistant materials of construction such as special 
alloys or fiberglass-reinforced plastic;
    (B) Corrosion-resistant coating (such as epoxy or fiberglass) with 
cathodic protection (e.g., impressed current or sacrificial anodes); and
    (C) Electrical isolation devices such as insulating joints and 
flanges.

    Note: The practices described in the National Association of 
Corrosion Engineers (NACE) standard, ``Recommended Practice (RP-02-85)--
Control of External Corrosion on Metallic Buried, Partially Buried, or 
Submerged Liquid Storage Systems,'' and the American Petroleum Institute 
(API) Publication 1632, ``Cathodic Protection of Underground Petroleum 
Storage Tanks and Piping Systems,'' may be used, where applicable, as 
guidelines in providing corrosion protection for tank systems.

    (4) For underground tank system components that are likely to be 
affected by vehicular traffic, a determination of design or operational 
measures that will protect the tank system against potential damage; and
    (5) Design considerations to ensure that:
    (i) Tank foundations will maintain the load of a full tank;
    (ii) Tank systems will be anchored to prevent flotation or 
dislodgement where the tank system is placed in a saturated zone, or is 
located within a seismic fault zone; and
    (iii) Tank systems will withstand the effects of frost heave.
    (b) The owner or operator of a new tank system must ensure that 
proper handling procedures are adhered to in order to prevent damage to 
the system during installation. Prior to covering, enclosing, or placing 
a new tank system or component in use, an independent, qualified 
installation inspector or an independent, qualified, registered 
professional engineer, either of whom is trained and experienced in the 
proper installation of tank systems, must inspect the system or 
component for the presence of any of the following items:
    (1) Weld breaks;
    (2) Punctures;
    (3) Scrapes of protective coatings;
    (4) Cracks;
    (5) Corrosion;
    (6) Other structural damage or inadequate construction or 
installation.

All discrepancies must be remedied before the tank system is covered, 
enclosed, or placed in use.
    (c) New tank systems or components and piping that are placed 
underground and that are backfilled must be provided with a backfill 
material that is a noncorrosive, porous, homogeneous substance and that 
is carefully installed so that the backfill is placed completely around 
the tank and compacted to ensure that the tank and piping are fully and 
uniformly supported.
    (d) All new tanks and ancillary equipment must be tested for 
tightness prior to being covered, enclosed or placed in use. If a tank 
system is found not to be tight, all repairs necessary to remedy the 
leak(s) in the system must be performed prior to the tank system being 
covered, enclosed, or placed in use.
    (e) Ancillary equipment must be supported and protected against 
physical damage and excessive stress due to settlement, vibration, 
expansion or contraction.

    Note: The piping system installation procedures described in 
American Petroleum Institute (API) Publication 1615 (November 1979), 
``Installation of Underground Petroleum Storage Systems,'' or ANSI 
Standard B31.3, ``Petroleum Refinery System,'' may be used, where 
applicable, as guidelines for proper installation of piping systems.

    (f) The owner or operator must provide the type and degree of 
corrosion protection necessary, based on the information provided under 
paragraph

[[Page 434]]

(a)(3) of this section, to ensure the integrity of the tank system 
during use of the tank system. The installation of a corrosion 
protection system that is field fabricated must be supervised by an 
independent corrosion expert to ensure proper installation.
    (g) The owner or operator must obtain and keep on file at the 
facility written statements by those persons required to certify the 
design of the tank system and supervise the installation of the tank 
system in accordance with the requirements of paragraphs (b) through (f) 
of this section to attest that the tank system was properly designed and 
installed and that repairs, pursuant to paragraphs (b) and (d) of this 
section were performed. These written statements must also include the 
certification statement as required in Sec. 270.11(d) of this chapter.

    (iii) Provided with a built-in, continuous leak detection system 
capable of detecting a release within 24 hours or at the earliest 
practicable time, if the owner or operator can demonstrate to the 
Regional Administrator, and the Regional Administrator concurs, that the 
existing leak detection technology or site conditions will not allow 
detection of a release within 24 hours.

    Note: The provisions outlined in the Steel Tank Institute's (STI) 
``Standard for Dual Wall Underground Steel Storage Tank'' may be used as 
guidelines for aspects of the design of underground steel double-walled 
tanks.

    (f) Ancillary equipment must be provided with full secondary 
containment (e.g., trench, jacketing, double-walled piping) that meets 
the requirements of paragraphs (b) and (c) of this section except for:
    (1) Aboveground piping (exclusive of flanges, joints, valves, and 
connections) that are visually inspected for leaks on a daily basis;
    (2) Welded flanges, welded joints, and welded connections that are 
visually inspected for leaks on a daily basis;
    (3) Sealless or magnetic coupling pumps and sealless valves, that 
are visually inspected for leaks on a daily basis; and
    (4) Pressurized aboveground piping systems with automatic shut-off 
devices (e.g., excess flow check valves, flow metering shutdown devices, 
loss of pressure actuated shut-off devices) that are visually inspected 
for leaks on a daily basis.
    (g) The owner or operator may obtain a variance from the 
requirements of this Section if the Regional Administrator finds, as a 
result of a demonstration by the owner or operator, either: that 
alternative design and operating practices, together with location 
characteristics, will prevent the migration of hazardous waste or 
hazardous constituents into the ground water or surface water at least 
as effectively as secondary containment during the active life of the 
tank system  or that in the event of a release that does migrate to 
ground water or surface water, no substantial present or potential 
hazard will be posed to human health or the environment. New underground 
tank systems may not, per a demonstration in accordance with paragraph 
(g)(2) of this section, be exempted from the secondary containment 
requirements of this section. Application for a variance as allowed in 
paragraph (g) of this section does not waive compliance with the 
requirements of this subpart for new tank systems.
    (1) In deciding whether to grant a variance based on a demonstration 
of equivalent protection of ground water and surface water, the Regional 
Administrator will consider:
    (i) The nature and quantity of the waste;
    (ii) The proposed alternate design and operation;
    (iii) The hydrogeologic setting of the facility, including the 
thickness of soils between the tank system and ground water; and
    (iv) All other factors that would influence the quality and mobility 
of the hazardous constituents and the potential for them to migrate to 
ground water or surface water.
    (2) In deciding whether to grant a variance, based on a 
demonstration of no substantial present or potential hazard, the 
Regional Administrator will consider:
    (i) The potential adverse effects on ground water, surface water, 
and land quality taking into account:
    (A) The physical and chemical characteristics of the waste in the 
tank system, including its potential for migration,
    (B) The hydrogeological characteristics of the facility and 
surrounding land,
    (C) The potential for health risks caused by human exposure to waste 
constituents,
    (D) The potential for damage to wildlife, crops, vegetation, and 
physical structures caused by exposure to waste constituents, and
    (E) The persistence and permanence of the potential adverse effects;
    (ii) The potential adverse effects of a release on ground-water 
quality, taking into account:
    (A) The quantity and quality of ground water and the direction of 
ground-water flow,
    (B) The proximity and withdrawal rates of water in the area,
    (C) The current and future uses of ground water in the area, and
    (D) The existing quality of ground water, including other sources of 
contamination and their cumulative impact on the ground-water quality;
    (iii) The potential adverse effects of a release on surface water 
quality, taking into account:

[[Page 437]]

    (A) The quantity and quality of ground water and the direction of 
ground-water flow,
    (B) The patterns of rainfall in the region,
    (C) The proximity of the tank system to surface waters,
    (D) The current and future uses of surface waters in the area and 
any water quality standards established for those surface waters, and
    (E) The existing quality of surface water, including other sources 
of contamination and the cumulative impact on surface-water quality; and
    (iv) The potential adverse effects of a release on the land 
surrounding the tank system, taking into account:
    (A) The patterns of rainfall in the region, and
    (B) The current and future uses of the surrounding land.
    (3) The owner or operator of a tank system, for which a variance 
from secondary containment had been granted in accordance with the 
requirements of paragraph (g)(1) of this section, at which a release of 
hazardous waste has occurred from the primary tank system but has not 
migrated beyond the zone of engineering control (as established in the 
variance), must:
    (i) Comply with the requirements of Sec. 265.196, except paragraph 
(d); and
    (ii) Decontaminate or remove contaminated soil to the extent 
necessary to:
    (A) Enable the tank system, for which the variance was granted, to 
resume operation with the capability for the detection of and response 
to releases at least equivalent to the capability it had prior to the 
release, and
    (B) Prevent the migration of hazardous waste or hazardous 
constituents to ground water or surface water; and
    (iii) If contaminated soil cannot be removed or decontaminated in 
accordance with paragraph (g)(3)(ii) of this section, comply with the 
requirements of Sec. 265.197(b);
    (4) The owner or operator of a tank system, for which a variance 
from secondary containment had been granted in accordance with the 
requirements of paragraph (g)(1) of this section, at which a release of 
hazardous waste has occurred from the primary tank system and has 
migrated beyond the zone of engineering control (as established in the 
variance), must:
    (i) Comply with the requirements of Sec. 265.196(a), (b), (c), and 
(d); and
    (ii) Prevent the migration of hazardous waste or hazardous 
constituents to ground water or surface water, if possible, and 
decontaminate or remove contaminated soil. If contaminated soil cannot 
be decontaminated or removed, or if ground water has been contaminated, 
the owner or operator must comply with the requirements of 
Sec. 265.197(b);
    (iii) If repairing, replacing, or reinstalling the tank system, 
provide secondary containment in accordance with the requirements of 
paragraphs (a) through (f) of this section or reapply for a variance 
from secondary containment and meet the requirements for new tank 
systems in Sec. 265.192 if the tank system is replaced. The owner or 
operator must comply with these requirements even if contaminated soil 
can be decontaminated or removed, and ground water or surface water has 
not been contaminated.
    (h) The following procedures must be followed in order to request a 
variance from secondary containment:
    (1) The Regional Administrator must be notified in writing by the 
owner or operator that he intends to conduct and submit a demonstration 
for a variance from secondary containment as allowed in paragraph (g) of 
this section according to the following schedule:
    (i) For existing tank systems, at least 24 months prior to the date 
that secondary containment must be provided in accordance with paragraph 
(a) of this section; and
    (ii) For new tank systems, at least 30 days prior to entering into a 
contract for installation of the tank system.
    (2) As part of the notification, the owner or operator must also 
submit to the Regional Administrator a description of the steps 
necessary to conduct the demonstration and a timetable for completing 
each of the steps. The demonstration must address each of the factors 
listed in paragraph (g)(1) or paragraph (g)(2) of this section.
    (3) The demonstration for a variance must be completed and submitted 
to the Regional Administrator within 180

[[Page 438]]

days after notifying the Regional Administrator of intent to conduct the 
demonstration.
    (4) The Regional Administrator will inform the public, through a 
newspaper notice, of the availability of the demonstration for a 
variance. The notice shall be placed in a daily or weekly major local 
newspaper of general circulation and shall provide at least 30 days from 
the date of the notice for the public to review and comment on the 
demonstration for a variance. The Regional Administrator also will hold 
a public hearing, in response to a request or at his own discretion, 
whenever such a hearing might clarify one or more issues concerning the 
demonstration for a variance. Public notice of the hearing will be given 
at least 30 days prior to the date of the hearing and may be given at 
the same time as notice of the opportunity for the public to review and 
comment on the demonstration. These two notices may be combined.
    (5) The Regional Administrator will approve or disapprove the 
request for a variance within 90 days of receipt of the demonstration 
from the owner or operator and will notify in writing the owner or 
operator and each person who submitted written comments or requested 
notice of the variance decision. If the demonstration for a variance is 
incomplete or does not include sufficient information, the 90-day time 
period will begin when the Regional Administrator receives a complete 
demonstration, including all information necessary to make a final 
determination. If the public comment period in paragraph (h)(4) of this 
section is extended, the 90-day time period will be similarly extended.
    (i) All tank systems, until such time as secondary containment 
meeting the requirements of this section is provided, must comply with 
the following:
    (1) For non-enterable underground tanks, a leak test that meets the 
requirements of Sec. 265.191(b)(5) must be conducted at least annually;
    (2) For other than non-enterable underground tanks and for all 
ancillary equipment, an annual leak test, as described in paragraph 
(i)(1) of this section, or an internal inspection or other tank 
integrity examination by an independent, qualified, registered 
professional engineer that addresses cracks, leaks, corrosion, and 
erosion must be conducted at least annually. The owner or operator must 
remove the stored waste from the tank, if necessary, to allow the 
condition of all internal tank surfaces to be assessed.

    Note: The practices described in the American Petroleum Institute 
(API) Publication Guide for Inspection of Refining Equipment, Chapter 
XIII, ``Atmospheric and Low Pressure Storage Tanks,'' 4th edition, 1981, 
may be used, when applicable, as guidelines for assessing the overall 
condition of the tank system.
    (3) The owner or operator must maintain on file at the facility a 
record of the results of the assessments conducted in accordance with 
paragraphs (i)(1) through (i)(3) of this section.
    (4) If a tank system or component is found to be leaking or unfit-
for-use as a result of the leak test or assessment in paragraphs (i)(1) 
through (i)(3) of this section, the owner or operator must comply with 
the requirements of Sec. 265.196.

53 FR 34087, Sept. 2, 1988]



Sec. 265.194  General operating requirements.

    (a) Hazardous wastes or treatment reagents must not be placed in a 
tank system if they could cause the tank, its ancillary equipment, or 
the secondary containment system to rupture, leak, corrode, or otherwise 
fail.
    (b) The owner or operator must use appropriate controls and 
practices to prevent spills and overflows from tank or secondary 
containment systems. These include at a minimum:
    (1) Spill prevention controls (e.g , check valves, dry discount 
couplings);
    (2) Overfill prevention controls (e.g , level sensing devices, high 
level alarms, automatic feed cutoff, or bypass to a standby tank); and
    (3) Maintenance of sufficient freeboard in uncovered tanks to 
prevent overtopping by wave or wind action or by precipitation.
    (c) The owner or operator must comply with the requirements of 
Sec. 265.196 if a leak or spill occurs in the tank system.


[[Page 439]]





Sec. 265.195  Inspections.

    (a) The owner or operator must inspect, where present, at least once 
each operating day:
    (1) Overfill/spill control equipment (e.g., waste-feed cutoff 
systems, bypass systems, and drainage systems) to ensure that it is in 
good working order;
    (2) The aboveground portions of the tank system, if any, to detect 
corrosion or releases of waste;
    (3) Data gathered from monitoring equipment and leak-detection 
equipment, (e.g., pressure and temperature gauges, monitoring wells) to 
ensure that the tank system is being operated according to its design; 
and
    (4) The construction materials and the area immediately surrounding 
the externally accessible portion of the tank system including secondary 
containment structures (e.g., dikes) to detect erosion or signs of 
releases of hazardous waste (e.g., wet spots, dead vegetation);

    Note: Section 265.15(c) requires the owner or operator to remedy any 
deterioration or malfunction he finds. Section 265.196 requires the 
owner or operator to notify the Regional Administrator within 24 hours 
of confirming a release. Also, 40 CFR part 302 may require the owner or 
operator to notify the National Response Center of a release.

    (b) The owner or operator must inspect cathodic protection systems, 
if present, according to, at a minimum, the following schedule to ensure 
that they are functioning properly:
    (1) The proper operation of the cathodic protection system must be 
confirmed within six months after initial installation, and annually 
thereafter; and
    (2) All sources of impressed current must be inspected and/or 
tested, as appropriate, at least bimonthly (i.e., every other month).

    Note: The practices described in the National Association of 
Corrosion Engineers (NACE) standard, ``Recommended Practice (RP-02-85)--
Control of External Corrosion on Metallic Buried, Partially Buried, or 
Submerged Liquid Storage Systems,'' and the American Petroleum Institute 
(API) Publication 1632, ``Cathodic Protection of Underground Petroleum 
Storage Tanks and Piping Systems,'' may be used, where applicable, as 
guidelines in maintaining and inspecting cathodic protection systems.

    (c) The owner or operator must document in the operating record of 
the facility an inspection of those items in paragraphs (a) and (b) of 
this section.



Sec. 265.196  Response to leaks or spills and disposition of leaking or unfit-for-use tank systems.

    A tank system or secondary containment system from which there has 
been a leak or spill, or which is unfit for use, must be removed from 
service immediately, and the owner or operator must satisfy the 
following requirements:
    (a) Cessation of use; prevent flow or addition of wastes. The owner 
or operator must immediately stop the flow of hazardous waste into the 
tank system or secondary containment system and inspect the system to 
determine the cause of the release.
    (b) Removal of waste from tank system or secondary containment 
system. (1) If the release was from the tank system, the owner or 
operator must, within 24 hours after detection of the leak or, if the 
owner or operator demonstrates that that is not possible, at the 
earliest practicable time remove as much of the waste as is necessary to 
prevent further release of hazardous waste to the environment and to 
allow inspection and repair of the tank system to be performed.
    (2) If the release was to a secondary containment system, all 
released materials must be removed within 24 hours or in as timely a 
manner as is possible to prevent harm to human health and the 
environment.
    (c) Containment of visible releases to the environment. The owner or 
operator must immediately conduct a visual inspection of the release 
and, based upon that inspection:
    (1) Prevent further migration of the leak or spill to soils or 
surface water; and
    (2) Remove, and properly dispose of, any visible contamination of 
the soil or surface water.
    (d) Notifications, reports. (1) Any release to the environment, 
except as provided in paragraph (d)(2) of this section, must be reported 
to the Regional Administrator within 24 hours of detection. If the 
release has been reported

[[Page 440]]

pursuant to 40 CFR part 302, that report will satisfy this requirement.
    (2) A leak or spill of hazardous waste that is:
    (i) Less than or equal to a quantity of one (1) pound, and
    (ii) Immediately contained and cleaned-up is exempted from the 
requirements of this paragraph.
    (3) Within 30 days of detection of a release to the environment, a 
report containing the following information must be submitted to the 
Regional Administrator:
    (i) Likely route of migration of the release;
    (ii) Characteristics of the surrounding soil (soil composition, 
geology, hydrogeology, climate);
    (iii) Results of any monitoring or sampling conducted in connection 
with the release, (if available). If sampling or monitoring data 
relating to the release are not available within 30 days, these data 
must be submitted to the Regional Administrator as soon as they become 
available;
    (iv) Proximity to downgradient drinking water, surface water, and 
population areas; and
    (v) Description of response actions taken or planned.
    (e) Provision of secondary containment, repair, or closure. (1) 
Unless the owner or operator satisfies the requirements of paragraphs 
(e) (2) through (4) of this section, the tank system must be closed in 
accordance with Sec. 265.197.
    (2) If the cause of the release was a spill that has not damaged the 
integrity of the system, the owner/operator may return the system to 
service as soon as the released waste is removed and repairs, if 
necessary, are made.
    (3) If the cause of the release was a leak from the primary tank 
system into the secondary containment system, the system must be 
repaired prior to returning the tank system to service.
    (4) If the source of the release was a leak to the environment from 
a component of a tank system without secondary containment, the owner/
operator must provide the component of the system from which the leak 
occurred with secondary containment that satisfies the requirements of 
Sec. 265.193 before it can be returned to service, unless the source of 
the leak is an aboveground portion of a tank system. If the source is an 
aboveground component that can be inspected visually, the component must 
be repaired and may be returned to service without secondary containment 
as long as the requirements of paragraph (f) of this section are 
satisfied. If a component is replaced to comply with the requirements of 
this subparagraph, that component must satisfy the requirements for new 
tank systems or components in Secs. 265.192 and 265.193. Additionally, 
if a leak has occurred in any portion of a tank system component that is 
not readily accessible for visual inspection (e.g., the bottom of an 
inground or onground tank), the entire component must be provided with 
secondary containment in accordance with Sec. 265.193 prior to being 
returned to use.
    (f) Certification of major repairs. If the owner or operator has 
repaired a tank system in accordance with paragraph (e) of this section, 
and the repair has been extensive (e.g., installation of an internal 
liner; repair of a ruptured primary containment or secondary containment 
vessel), the tank system must not be returned to service unless the 
owner/operator has obtained a certification by an independent, 
qualified, registered professional engineer in accordance with 
Sec. 270.11(d) that the repaired system is capable of handling hazardous 
wastes without release for the intended life of the system. This 
certification must be submitted to the Regional Administrator within 
seven days after returning the tank system to use.

    Note: The Regional Administrator may, on the basis of any 
information received that there is or has been a release of hazardous 
waste or hazardous constituents into the environment, issue an order 
under RCRA section 3004(v), 3008(h), or 7003(a) requiring corrective 
action or such other response as deemed necessary to protect human 
health or the environment.

    Note: See Sec. 265.15(c) for the requirements necessary to remedy a 
failure. Also, 40 CFR Part 302 requires the owner or operator to notify 
the National Response Center of a release of any ``reportable 
quantity.''

[[Page 441]]



Sec. 265.197  Closure and post-closure care.

    (a) At closure of a tank system, the owner or operator must remove 
or decontaminate all waste residues, contaminated containment system 
components (liners, etc.), contaminated soils, and structures and 
equipment contaminated with waste, and manage them as hazardous waste, 
unless Sec. 261.3(d) of this Chapter applies. The closure plan, closure 
activities, cost estimates for closure, and financial responsibility for 
tank systems must meet all of the requirements specified in subparts G 
and H of this part.
    (b) If the owner or operator demonstrates that not all contaminated 
soils can be practicably removed or decontaminated as required in 
paragraph (a) of this section, then the owner or operator must close the 
tank system and perform post-closure care in accordance with the closure 
and post-closure care requirements that apply to landfills 
(Sec. 265.310) In addition, for the purposes of closure, post-closure, 
and financial responsibility, such a tank system is then considered to 
be a landfill, and the owner or operator must meet all of the 
requirements for landfills specified in subparts G and H of this part.
    (c) If an owner or operator has a tank system which does not have 
secondary containment that meets the requirements of Sec. 265.193(b) 
through (f) and which is not exempt from the secondary containment 
requirements in accordance with Sec. 265.193(g), then,
    (1) The closure plan for the tank system must include both a plan 
for complying with paragraph (a) of this section and a contingent plan 
for complying with paragraph (b) of this section.
    (2) A contingent post-closure plan for complying with paragraph (b) 
of this section must be prepared and submitted as part of the permit 
application.
    (3) The cost estimates calculated for closure and post-closure care 
must reflect the costs of complying with the contingent closure plan and 
the contingent post-closure plan, if these costs are greater than the 
costs of complying with the closure plan prepared for the expected 
closure under paragraph (a) of this section.
    (4) Financial assurance must be based on the cost estimates in 
paragraph (c)(3) of this section.
    (5) For the purposes of the contingent closure and post-closure 
plans, such a tank system is considered to be a landfill, and the 
contingent plans must meet all of the closure, post-closure, and 
financial responsibility requirements for landfills under subparts G and 
H of this part.



Sec. 265.198  Special requirements for ignitable or reactive wastes.

    (a) Ignitable or reactive waste must not be placed in a tank system, 
unless:
    (1) The waste is treated, rendered, or mixed before or immediately 
after placement in the tank system so that:
    (i) The resulting waste, mixture, or dissolved material no longer 
meets the definition of ignitable or reactive waste under Secs. 261.21 
or 261.23 of this chapter; and
    (ii) Section 265.17(b) is complied with; or
    (2) The waste is stored or treated in such a way that it is 
protected from any material or conditions that may cause the waste to 
ignite or react; or
    (3) The tank system is used solely for emergencies.
    (b) The owner or operator of a facility where ignitable or reactive 
waste is stored or treated in tanks must comply with the requirements 
for the maintenance of protective distances between the waste management 
area and any public ways, streets, alleys, or an adjoining property line 
that can be built upon as required in Tables 2-1 through 2-6 of the 
National Fire Protection Association's ``Flammable and Combustible 
Liquids Code,'' (1977 or 1981), (incorporated by reference, see 
Sec. 260.11).



Sec. 265.199  Special requirements for incompatible wastes.

    (a) Incompatible wastes, or incompatible waste and materials, must 
not be placed in the same tank system, unless Sec. 265.17(b) is complied 
with.
    (b) Hazardous waste must not be placed in a tank system that has not 
been decontaminated and that previously held an incompatible waste or 
material, unless Sec. 265.17(b) is complied with.

[[Page 442]]



Sec. 265.200  Waste analysis and trial tests.

    In addition to performing the waste analysis required by 
Sec. 265.13, the owner or operator must, whenever a tank system is to be 
used to treat chemically or to store a hazardous waste that is 
substantially different from waste previously treated or stored in that 
tank system; or treat chemically a hazardous waste with a substantially 
different process than any previously used in that tank system:
    (a) Conduct waste analyses and trial treatment or storage tests 
(e.g., bench-scale or pilot-plant scale tests); or
    (b) Obtain written, documented information on similar waste under 
similar operating conditions to show that the proposed treatment or 
storage will meet the requirements of Sec. 265.194(a).

    Note: Section 265.13 requires the waste analysis plan to include 
analyses needed to comply with Secs. 265.198 and 265.199. Section 265.73 
requires the owner or operator to place the results from each waste 
analysis and trial test, or the documented information, in the operating 
record of the facility.



Sec. 265.201  Special requirements for generators of between 100 and 1,000 kg/mo that accumulate hazardous waste in tanks.

    (a) The requirements of this section apply to small quantity 
generators of more than 100 kg but less than 1,000 kg of hazardous waste 
in a calendar month, that accumulate hazardous waste in tanks for less 
than 180 days (or 270 days if the generator must ship the waste greater 
than 200 miles), and do not accumulate over 6,000 kg on-site at any 
time.
    (b) Generators of between 100 and 1,000 kg/mo hazardous waste must 
comply with the following general operating requirements:
    (1) Treatment or storage of hazardous waste in tanks must comply 
with Sec. 265.17(b).
    (2) Hazardous wastes or treatment reagents must not be placed in a 
tank if they could cause the tank or its inner liner to rupture, leak, 
corrode, or otherwise fail before the end of its intended life.
    (3) Uncovered tanks must be operated to ensure at least 60 
centimeters (2 feet) of freeboard, unless the tank is equipped with a 
containment structure (e.g., dike or trench), a drainage control system, 
or a diversion structure (e.g., standby tank) with a capacity that 
equals or exceeds the volume of the top 60 centimeters (2 feet) of the 
tank.
    (4) Where hazardous waste is continuously fed into a tank, the tank 
must be equipped with a means to stop this inflow (e.g., waste feed 
cutoff system or by-pass system to a stand-by tank).

    Note: These systems are intended to be used in the event of a leak 
or overflow from the tank due to a system failure (e.g., a malfunction 
in the treatment process, a crack in the tank, etc.).

    (c) Generators of between 100 and 1,000 kg/mo accumulating hazardous 
waste in tanks must inspect, where present:
    (1) Discharge control equipment (e.g., waste feed cutoff systems, 
by-pass systems, and drainage systems) at least once each operating day, 
to ensure that it is in good working order;
    (2) Data gathered from monitoring equipment (e.g., pressure and 
temperature gauges) at least once each operating day to ensure that the 
tank is being operated according to its design;
    (3) The level of waste in the tank at least once each operating day 
to ensure compliance with Sec. 265.201(b)(3);
    (4) The construction materials of the tank at least weekly to detect 
corrosion or leaking of fixtures or seams; and
    (5) The construction materials of, and the area immediately 
surrounding, discharge confinement structures (e.g., dikes) at least 
weekly to detect erosion or obvious signs of leakage (e.g., wet spots or 
dead vegetation).

    Note: As required by Sec. 265.15(c), the owner or operator must 
remedy any deterioration or malfunction he finds.

    (d) Generators of between 100 and 1,000 kg/mo accumulating hazardous 
waste in tanks must, upon closure of the facility, remove all hazardous 
waste from tanks, discharge control equipment, and discharge confinement 
structures.

    Note: At closure, as throughout the operating period, unless the 
owner or operator can demonstrate, in accordance with Sec. 261.3(c) or 
(d) of this chapter, that any solid

[[Page 443]]

waste removed from his tank is not a hazardous waste, the owner or 
operator becomes a generator of hazardous waste and must manage it in 
accordance with all applicable requirements of parts 262, 263, and 265 
of this chapter.

    (e) Generators of between 100 and 1,000 kg/mo must comply with the 
following special requirements for ignitable or reactive waste:
    (1) Ignitable or reactive waste must not be placed in a tank, 
unless:
    (i) The waste is treated, rendered, or mixed before or immediately 
after placement in a tank so that (A) the resulting waste, mixture, or 
dissolution of material no longer meets the definition of ignitable or 
reactive waste under Sec. 261.21 or Sec. 261.23 of this chapter, and (B) 
Sec. 265.17(b) is complied with; or
    (ii) The waste is stored or treated in such a way that it is 
protected from any material or conditions that may cause the waste to

                     Subpart K--Surface Impoundments



Sec. 265.220  Applicability.

    The regulations in this subpart apply to owners and operators of 
facilities that use surface impoundments to treat, store, or dispose of 
hazardous waste, except as Sec. 265.1 provides otherwise.



Sec. 265.221  Design and operating requirements.

    (a) The owner or operator of each new surface impoundment unit on 
which construction commences after January 29, 1992, each lateral 
expansion of a surface impoundment unit on which construction commences 
after July 29, 1992, and each replacement of an existing surface 
impoundment unit that is to commence reuse after July 29, 1992 must 
install two or more liners and a leachate collection and removal system 
between such liners, and operate the leachate collection and removal 
system, in accordance with Sec. 264.221(c), unless exempted under 
Sec. 264.221(d), (e), or (f), of this chapter. ``Construction 
commences'' is as defined in Sec. 260.10 of this chapter under 
``existing facility.''
    (b) The owner or operator of each unit referred to in paragraph (a) 
of this section must notify the Regional Administrator at least sixty 
days prior to receiving waste. The owner or operator of each facility 
submitting notice must file a part B application within six months of 
the receipt of such notice.
    (c) The owner or operator of any replacement surface impoundment 
unit is exempt from paragraph (a) of this section if:
    (1) The existing unit was constructed in compliance with the design 
standards of Sec. 3004(o)(1)(A)(i) and (o)(5) of the Resource 
Conservation and Recovery Act; and
    (2) There is no reason to believe that the liner is not functioning 
as designed.
    (d) The double liner requirement set forth in paragraph (a) of this 
section

[[Page 444]]

may be waived by the Regional Administrator for any monofill, if:
    (1) The monofill contains only hazardous wastes from foundry furnace 
emission controls or metal casting molding sand, and such wastes do not 
contain constituents which would render the wastes hazardous for reasons 
other than the Toxicity Characteristic in Sec. 261.24 of this chapter, 
with EPA Hazardous Waste Numbers D004 through D017; and
    (2)(i)(A) The monofill has at least one liner for which there is no 
evidence that such liner in leaking. For the purposes of this paragraph 
the term ``liner'' means a liner designed, constructed, installed, and 
operated to prevent hazardous waste from passing into the liner at any 
time during the active life of the facility, or a liner designed, 
constructed, installed, and operated to prevent hazardous waste from 
migrating beyond the liner to adjacent subsurface soil, ground water, or 
surface water at any time during the active life of the facility. In the 
case of any surface impoundment which has been exempted from the 
requirements of paragraph (a) of this section on the basis of a liner 
designed, constructed, installed, and operated to prevent hazardous 
waste from passing beyond the liner, at the closure of such impoundment 
the owner or operator must remove or decontaminate all waste residues, 
all contaminated liner material, and contaminated soil to the extent 
practicable. If all contaminated soil it is not removed or 
decontaminated, the owner of operator of such impoundment must comply 
with appropriate post-closure requirements, including but not limited to 
ground-water monitoring and corrective action;
    (B) The monofill is located more than one-quarter mile from an 
underground source of drinking water (as that term is defined in 
Sec. 144.3 of this chapter); and
    (C) The monofill is in compliance with generally applicable ground-
water monitoring requirements for facilities with permits under RCRA 
section 3005(c); or
    (ii) The owner or operator demonstrates that the monofill is 
located, designed and operated so as to assure that there will be no 
migration of any hazardous constituent into ground water or surface 
water at any future time.
    (e) In the case of any unit in which the liner and leachate 
collection system has been installed pursuant to the requirements of 
paragraph (a) of this section and in good faith compliance with 
paragraph (a) of this section and with guidance documents governing 
liners and leachate collection systems under paragraph (a) of this 
section, no liner or leachate collection system which is different from 
that which was so installed pursuant to paragraph (a) of this section 
will be required for such unit by the Regional Administrator when 
issuing the first permit to such facility, except that the Regional 
Administrator will not be precluded from requiring installation of a new 
liner when the Regional Administrator has reason to believe that any 
liner installed pursuant to the requirements of paragraph (a) of this 
section is leaking.
    (f) A surface impoundment must maintain enough freeboard to prevent 
any overtopping of the dike by overfilling, wave action, or a storm. 
Except as provided in paragraph (b) of this section, there must be at 
least 60 centimeters (two feet) of freeboard.
    (g) A freeboard level less than 60 centimeters (two feet) may be 
maintained if the owner or operator obtains certification by a qualified 
engineer that alternate design features or operating plans will, to the 
best of his knowledge and opinion, prevent overtopping of the dike. The 
certification, along with a written identification of alternate design 
features or operating plans preventing overtopping, must be maintained 
at the facility.
    (h) Surface impoundments that are newly subject to RCRA section 
3005(j)(1) due to the promulgation of additional listings or 
characteristics for the identification of hazardous waste must be in 
compliance with paragraphs (a), (c) and (d) of this section not later 
than 48 months after the promulgation of the additional listing or 
characteristic. This compliance period shall not be cut short as the 
result of the promulgation of land disposal prohibitions under part 268 
of this chapter or the granting of an extension to the effective date of

[[Page 445]]

a prohibition pursuant to Sec. 268.5 of this chapter, within this 48-
month period.

Sec. 265.222  Action leakage rate.

    (a) The owner or operator of surface impoundment units subject to 
Sec. 265.221(a) must submit a proposed action leakage rate to the 
Regional Administrator when submitting the notice required under 
Sec. 265.221(b). Within 60 days of receipt of the notification, the 
Regional Administrator will: Establish an action leakage rate, either as 
proposed by the owner or operator or modified using the criteria in this 
section; or extend the review period for up to 30 days. If no action is 
taken by the Regional Administrator before the original 60 or extended 
90 day review periods, the action leakage rate will be approved as 
proposed by the owner or operator.
    (b) The Regional Administrator shall approve an action leakage rate 
for surface impoundment units subject to Sec. 265.221(a). The action 
leakage rate is the maximum design flow rate that the leak detection 
system (LDS) can remove without the fluid head on the bottom liner 
exceeding 1 foot. The action leakage rate must include an adequate 
safety margin to allow for uncertainties in the design (e.g., slope, 
hydraulic conductivity, thickness of drainage material), construction, 
operation, and location of the LDS, waste and leachate characteristics, 
likelihood and amounts of other sources of liquids in the LDS, and 
proposed response actions (e.g., the action leakage rate must consider 
decreases in the flow capacity of the system over time resulting from 
siltation and clogging, rib layover and creep of synthetic components of 
the system, overburden pressures, etc.).
    (c) To determine if the action leakage rate has been exceeded, the 
owner or operator must convert the weekly or monthly flow rate from the 
monitoring data obtained under Sec. 265.226(b), to an average daily flow 
rate (gallons per acre per day) for each sump. Unless the Regional 
Administrator approves a different calculation, the average daily flow 
rate for each sump must be calculated weekly during the active life and 
closure period, and if the unit closes in accordance with 
Sec. 265.228(a)(2), monthly during the post-closure care period when 
monthly monitoring is required under Sec. 265.226(b).

Sec. 265.223  Containment system.

    All earthen dikes must have a protective cover, such as grass, 
shale, or rock, to minimize wind and water erosion and to preserve their 
structural integrity.

    Editorial Note: At 57 FR 3492, Jan. 29, 1992 the Environmental 
Protection Agency added Sec. 265.223, effective July 29, 1992. Since a 
Sec. 265.223 already exists, both sections appear. An agency correction 
will be published in the Federal Register at a later date.



Sec. 265.223  Response actions.

    (a) The owner or operator of surface impoundment units subject to 
Sec. 265.221(a) must submit a response action plan to the Regional 
Administrator when submitting the proposed action leakage rate under 
Sec. 265.222. The response action plan must set forth the actions to be 
taken if the action leakage rate has been exceeded. At a minimum, the 
response action plan must describe the actions specified in paragraph 
(b) of this section.
    (b) If the flow rate into the leak detection system exceeds the 
action leakage rate for any sump, the owner or operator must:
    (1) Notify the Regional Administrator in writing of the exceedence 
within 7 days of the determination;
    (2) Submit a preliminary written assessment to the Regional 
Administrator within 14 days of the determination, as to the amount of 
liquids, likely sources of liquids, possible location, size, and cause 
of any leaks, and short-term actions taken and planned;
    (3) Determine to the extent practicable the location, size, and 
cause of any leak;
    (4) Determine whether waste receipt should cease or be curtailed, 
whether any waste should be removed from the unit for inspection, 
repairs, or controls, and whether or not the unit should be closed;

[[Page 446]]

    (5) Determine any other short-term and longer-term actions to be 
taken to mitigate or stop any leaks; and
    (6) Within 30 days after the notification that the action leakage 
rate has been exceeded, submit to the Regional Administrator the results 
of the analyses specified in paragraphs (b)(3), (4), and (5) of this 
section, the results of actions taken, and actions planned. Monthly 
thereafter, as long as the flow rate in the leak detection system 
exceeds the action leakage rate, the owner or operator must submit to 
the Regional Administrator a report summarizing the results of any 
remedial actions taken and actions planned.
    (c) To make the leak and/or remediation determinations in paragraphs 
(b)(3), (4), and (5) of this section, the owner or operator must:
    (1)(i) Assess the source of liquids and amounts of liquids by 
source,
    (ii) Conduct a fingerprint, hazardous constituent, or other analyses 
of the liquids in the leak detection system to identify the source of 
liquids and possible location of any leaks, and the hazard and mobility 
of the liquid; and
    (iii) Assess the seriousness of any leaks in terms of potential for 
escaping into the environment; or
    (2) Document why such assessments are not needed.

Sec. 265.224  [Reserved]



Sec. 265.225  Waste analysis and trial tests.

    (a) In addition to the waste analyses required by Sec. 265.13, 
whenever a surface impoundment is to be used to:
    (1) Chemically treat a hazardous waste which is substantially 
different from waste previously treated in that impoundment; or
    (2) Chemically treat hazardous waste with a substantially different 
process than any previously used in that impoundment; the owner or 
operator must, before treating the different waste or using the 
different process:
    (i) Conduct waste analyses and trial treatment tests (e.g., bench 
scale or pilot plant scale tests); or
    (ii) Obtain written, documented information on similar treatment of 
similar waste under similar operating conditions; to show that this 
treatment will comply with Sec. 265.17(b).

[Comment: As required by Sec. 265.13, the waste analysis plan must 
include analyses needed to comply with Secs. 265.229 and 265.230. As 
required by Sec. 265.73, the owner or operator must place the results 
from each waste analysis and trial test, or the documented information, 
in the operating record of the facility.]

    (b) [Reserved]



Sec. 265.226  Monitoring and inspection.

    (a) The owner or operator must inspect:
    (1) The freeboard level at least once each operating day to ensure 
compliance with Sec. 265.222, and
    (2) The surface impoundment, including dikes and vegetation 
surrounding the dike, at least once a week to detect any leaks, 
deterioration, or failures in the impoundment.
    (b)(1) An owner or operator required to have a leak detection system 
under Sec. 265.221(a) must record the amount of liquids removed from 
each leak detection system sump at least once each week during the 
active life and closure period.
    (2) After the final cover is installed, the amount of liquids 
removed from each leak detection system sump must be recorded at least 
monthly. If the liquid level in the sump stays below the pump operating 
level for two consecutive months, the amount of liquids in the sumps 
must be recorded at least quarterly. If the liquid level in the sump 
stays below the pump operating level for two consecutive quarters, the 
amount of liquids in the sumps must be recorded at least semi-annually. 
If at any time during the post-closure care period the pump operating 
level is exceeded at units on quarterly or semi-annual recording 
schedules, the owner or operator must return to monthly recording of 
amounts of liquids removed from each sump until the liquid level again 
stays below the pump operating level for two consecutive months.
    (3) ``Pump operating level'' is a liquid level proposed by the owner 
or operator and approved by the Regional Administrator based on pump 
activation level, sump dimensions, and level that avoids backup into the 
drainage layer and minimizes head in the sump. The timing for submission 
and approval of the

[[Page 447]]

proposed ``pump operating level'' will be in accordance with 
Sec. 265.222(a).

[Comment: As required by Sec. 265.15(c), the owner or operator must 
remedy any deterioration or malfunction he finds.]

Sec. 265.228  Closure and post-closure care.

    (a) At closure, the owner or operator must:
    (1) Remove or decontaminate all waste residues, contaminated 
containment system components (liners, etc.), contaminated subsoils, and 
structures and equipment contaminated with waste and leachate, and 
manage them as hazardous waste unless Sec. 261.3(d) of this chapter 
applies; or
    (2) Close the impoundment and provide post-closure care for a 
landfill under subpart G and Sec. 265.310, including the following:
    (i) Eliminate free liquids by removing liquid wastes or solidifying 
the remaining wastes and waste residues;
    (ii) Stabilize remaining wastes to a bearing capacity sufficient to 
support the final cover; and
    (iii) Cover the surface impoundment with a final cover designed and 
constructed to:
    (A) Provide long-term minimization of the migration of liquids 
through the closed impoundment;
    (B) Function with minimum maintenance;
    (C) Promote drainage and minimize erosion or abrasion of the cover;
    (D) Accomodate settling and subsidence so that the cover's integrity 
is maintained; and
    (E) Have a permeability less than or equal to the permeability of 
any bottom liner system or natural subsoils present.
    (b) In addition to the requirements of subpart G, and Sec. 265.310, 
during the post-closure care period, the owner or operator of a surface 
impoundment in which wastes, waste residues, or contaminated materials 
remain after closure in accordance with the provisions of paragraph 
(a)(2) of this section must:
    (1) Maintain the integrity and effectiveness of the final cover, 
including making repairs to the cover as necessary to correct the 
effects of settling, subsidence, erosion, or other events;
    (2) Maintain and monitor the leak detection system in accordance 
with Secs. 265.221(c)(2)(iv) and (3) of this chapter and 265.226(b) and 
comply with all other applicable leak detection system requirements of 
this part;

Sec. 265.255  Action leakage rates.

    (a) The owner or operator of waste pile units subject to 
Sec. 265.254 must submit a proposed action leakage rate to the Regional 
Administrator when submitting the notice required under Sec. 265.254. 
Within 60 days of receipt of the notification, the Regional 
Administrator will: Establish an action leakage rate, either as proposed 
by the owner or operator or modified using the criteria in this section; 
or extend the review period for up to 30 days. If no action is taken by 
the Regional Administrator before the original 60 or extended 90 day 
review periods, the action leakage rate will be approved as proposed by 
the owner or operator.
    (b) The Regional Administrator shall approve an action leakage rate 
for surface impoundment units subject to Sec. 265.254. The action 
leakage rate is the maximum design flow rate that the leak detection 
system (LDS) can remove without the fluid head on the bottom liner 
exceeding 1 foot. The action leakage rate must include an adequate 
safety margin to allow for uncertainties in the design (e.g., slope, 
hydraulic conductivity, thickness of drainage material), construction, 
operation, and location of the LDS, waste and leachate characteristics, 
likelihood and amounts of other sources of liquids in the LDS, and 
proposed response actions (e.g., the action leakage rate must consider 
decreases in the flow capacity of the system over time resulting from 
siltation and clogging, rib layover and creep of synthetic components of 
the system, overburden pressures, etc.).
    (c) To determine if the action leakage rate has been exceeded, the 
owner or operator must convert the weekly flow rate from the monitoring 
data obtained under Sec. 265.260, to an average daily flow rate (gallons 
per acre per day) for each sump. Unless the Regional Administrator 
approves a different calculation, the average daily flow rate for each 
sump must be calculated weekly during the active life and closure 
period.

Sec. 265.17(b) is complied with.
    (b) A pile of hazardous waste that is incompatible with any waste or 
other material stored nearby in other containers, piles, open tanks, or 
surface impoundments must be separated from the other materials, or 
protected from them by means of a dike, berm, wall, or other device.

[Comment: The purpose of this is to prevent fires, explosions, gaseous 
emissions, leaching, or other discharge of hazardous waste or hazardous 
waste constituents which could result from the contact or mixing of 
incompatible wastes or materials.]


[[Page 450]]


    (c) Hazardous waste must not be piled on the same area where 
incompatible wastes or materials were previously piled, unless that area 
has been decontaminated sufficiently to ensure compliance with 
Sec. 265.17(b).



Sec. 265.258  Closure and post-closure care.

    (a) At closure, the owner or operator must remove or decontaminate 
all waste residues, contaminated containment system components (liners, 
etc.), contaminated subsoils, and structures and equipment contaminated 
with waste and leachate, and manage them as hazardous waste unless 
Sec. 261.3(d) of this chapter applies; or
    (b) If, after removing or decontaminating all residues and making 
all reasonable efforts to effect removal or decontamination of 
contaminated components, subsoils, structures, and equipment as required 
in paragraph (a) of this section, the owner or operator finds that not 
all contaminated subsoils can be practicably removed or decontaminated, 
he must close the facility and perform post-closure care in accordance 
with the closure and post-closure requirements that apply to landfills 
(Sec. 265.310).

Sec. 265.259  Response actions.

    (a) The owner or operator of waste pile units subject to 
Sec. 265.254 must submit a response action plan to the Regional 
Administrator when submitting the proposed action leakage rate under 
Sec. 265.255. The response action plan must set forth the actions to be 
taken if the action leakage rate has been exceeded. At a minimum, the 
response action plan must describe the actions specified in paragraph 
(b) of this section.
    (b) If the flow rate into the leak determination system exceeds the 
action leakage rate for any sump, the owner or operator must:
    (1) Notify the Regional Administrator in writing of the exceedence 
within 7 days of the determination;
    (2) Submit a preliminary written assessment to the Regional 
Administrator within 14 days of the determination, as to the amount of 
liquids, likely sources of liquids, possible location, size, and cause 
of any leaks, and short-term actions taken and planned;
    (3) Determine to the extent practicable the location, size, and 
cause of any leak;
    (4) Determine whether waste receipts should cease or be curtailed, 
whether any waste should be removed from the unit for inspection, 
repairs, or controls, and whether or not the unit should be closed;
    (5) Determine any other short-term and longer-term actions to be 
taken to mitigate or stop any leaks; and
    (6) Within 30 days after the notification that the action leakage 
rate has been exceeded, submit to the Regional Administrator the results 
of the analyses specified in paragraphs (b)(3), (4), and (5) of this 
section, the results of actions taken, and actions planned. Monthly 
thereafter, as long as the flow rate in the leak detection system 
exceeds the action leakage rate, the owner or operator must submit to 
the Regional Administrator a report summarizing the results of any 
remedial actions taken and actions planned.
    (c) To make the leak and/or remediation determinations in paragraphs 
(b)(3), (4), and (5) of this section, the owner or operator must:
    (1)(i) Assess the source of liquids and amounts of liquids by 
source,
    (ii) Conduct a fingerprint, hazardous constituent, or other analyses 
of the liquids in the leak detection system to identify the source of 
liquids and possible location of any leaks, and the hazard and mobility 
of the liquid; and
    (iii) Assess the seriousness of any leaks in terms of potential for 
escaping into the environment; or
    (2) Document why such assessments are not needed.

section, no liner or leachate collection system which is different from 
that which was so installed pursuant to paragraph (a) of this section 
will be required for such unit by the Regional Administrator when 
issuing the first permit to such facility, except that the Regional 
Administrator will not be precluded from requiring installation of a new 
liner when the Regional Administrator has reason to believe that any 
liner installed pursuant to the requirements of paragraph (a) of this 
section is leaking.
    (f) The owner or operator must design, construct, operate, and 
maintain a run-on control system capable of preventing flow onto the 
active portion of the landfill during peak discharge from at least a 25-

Sec. 265.302  Action leakage rate.

    (a) The owner or operator of landfill units subject to 
Sec. 265.301(a) must submit a proposed action leakage rate to the 
Regional Administrator when submitting the notice required under 
Sec. 265.301(b). Within 60 days of receipt of the notification, the 
Regional Administrator will: Establish an action leakage rate, either as 
proposed by the owner or operator or modified using the criteria in this 
section; or extend the review period for up to 30 days. If no action is 
taken by the Regional Administrator before the original 60 or extended 
90 day review periods, the action leakage rate will be approved as 
proposed by the owner or operator.
    (b) The Regional Administrator shall approve an action leakage rate 
for surface impoundment units subject to Sec. 265.301(a). The action 
leakage rate is the maximum design flow rate that the leak detection 
system (LDS) can remove without the fluid head on the bottom liner 
exceeding 1 foot. The action leakage rate must include an adequate 
safety margin to allow for uncertainties in the design (e.g., slope, 
hydraulic conductivity, thickness of drainage material), construction, 
operation, and location of the LDS, waste and leachate characteristics, 
likelihood and amounts of other sources of liquids in the LDS, and 
proposed response actions (e.g., the action leakage rate must consider 
decreases in the

[[Page 457]]

flow capacity of the system over time resulting from siltation and 
clogging, rib layover and creep of synthetic components of the system, 
overburden pressures, etc.).
    (c) To determine if the action leakage rate has been exceeded, the 
owner or operator must convert the weekly or monthly flow rate from the 
monitoring data obtained under Sec. 265.304 to an average daily flow 
rate (gallons per acre per day) for each sump. Unless the Regional 
Administrator approves a different calculation, the average daily flow 
rate for each sump must be calculated weekly during the active life and 
closure period, and monthly during the post-closure care period when 
monthly monitoring is required under Sec. 265.304(b).

[57 FR 3494, Jan. 29, 1992]



Sec. 265.303  Response actions.

    (a) The owner or operator of landfill units subject to 
Sec. 265.301(a) must submit a response action plan to the Regional 
Administrator when submitting the proposed action leakage rate under 
Sec. 265.302. The response action plan must set forth the actions to be 
taken if the action leakage rate has been exceeded. At a minimum, the 
response action plan must describe the actions specified in paragraph 
(b) of this section.
    (b) If the flow rate into the leak detection system exceeds the 
action leakage rate for any sump, the owner or operator must:
    (1) Notify the Regional Administrator in writing of the exceedence 
within 7 days of the determination;
    (2) Submit a preliminary written assessment to the Regional 
Administrator within 14 days of the determination, as to the amount of 
liquids, likely sources of liquids, possible location, size, and cause 
of any leaks, and short-term actions taken and planned;
    (3) Determine to the extent practicable the location, size, and 
cause of any leak;
    (4) Determine whether waste receipt should cease or be curtailed, 
whether any waste should be removed from the unit for inspection, 
repairs, or controls, and whether or not the unit should be closed;
    (5) Determine any other short-term and longer-term actions to be 
taken to mitigate or stop any leaks; and
    (6) Within 30 days after the notification that the action leakage 
rate has been exceeded, submit to the Regional Administrator the results 
of the analyses specified in paragraphs (b)(3), (4), and (5) of this 
section, the results of actions taken, and actions planned. Monthly 
thereafter, as long as the flow rate in the leak detection system 
exceeds the action leakage rate, the owner or operator must submit to 
the Regional Administrator a report summarizing the results of any 
remedial actions taken and actions planned.
    (c) To make the leak and/or remediation determinations in paragraphs 
(b)(3), (4), and (5) of this section, the owner or operator must:
    (1)(i) Assess the source of liquids and amounts of liquids by 
source,
    (ii) Conduct a fingerprint, hazardous constituent, or other analyses 
of the liquids in the leak detection system to identify the source of 
liquids and possible location of any leaks, and the hazard and mobility 
of the liquid; and
    (iii) Assess the seriousness of any leaks in terms of potential for 
escaping into the environment; or
    (2) Document why such assessments are not needed.

[57 FR 3494, Jan. 29, 1992]



Sec. 265.304  Monitoring and inspection.

    (a) An owner or operator required to have a leak detection system 
under Sec. 265.301(a) must record the amount of liquids removed from 
each leak detection system sump at least once each week during the 
active life and closure period.
    (b) After the final cover is installed, the amount of liquids 
removed from each leak detection system sump must be recorded at least 
monthly. If the liquid level in the sump stays below the pump operating 
level for two consecutive months, the amount of liquids in the sumps 
must be recorded at least quarterly. If the liquid level in the sump 
stays below the pump operating level for two consecutive quarters, the 
amount of liquids in the sumps must be recorded at least semi-annually. 
If at any time during the post-closure care

[[Page 458]]

period the pump operating level is exceeded at units on quarterly or 
semi-annual recording schedules, the owner or operator must return to 
monthly recording of amounts of liquids removed from each sump until the 
liquid level again stays below the pump operating level for two 
consecutive months.
    (c) ``Pump operating level'' is a liquid level proposed by the owner 
or operator and approved by the Regional Administrator based on pump 
activation level, sump dimensions, and level that avoids backup into the 
drainage layer and minimizes head in the sump. The timing for submission 
and approval of the proposed ``pump operating level'' will be in 
accordance with Sec. 265.302(a).

    (a) Hazardous waste must be packaged in non-leaking inside 
containers. The inside containers must be of a design and constructed of 
a material that will not react dangerously with, be decomposed by, or be 
ignited by the waste held therein. Inside containers must be tightly and 
securely sealed. The inside containers must be of the size and type 
specified in the Department of Transportation (DOT) hazardous materials 
regulations (49 CFR parts 173, 178 and 179), if those regulations 
specify a particular inside container for the waste.
    (b) The inside containers must be overpacked in an open head DOT-
specification metal shipping container (49 CFR parts 178 and 179) of no 
more than 416-liter (110 gallon) capacity and surrounded by, at a 
minimum, a sufficient quantity of sorbent material, determined to be

    In addition to the waste analyses required by Sec. 265.13, the owner 
or operator must sufficiently analyze any waste which he has not 
previously burned in his incinerator to enable him to establish steady 
state (normal) operating conditions (including waste and auxiliary fuel 
feed and air flow) and to determine the type of pollutants which might 
be emitted. At a minimum, the analysis must determine:
    (a) Heating value of the waste;
    (b) Halogen content and sulfur content in the waste; and
    (c) Concentrations in the waste of lead and mercury, unless the 
owner or operator has written, documented data that show that the 
element is not present.

control must be monitored at least every 15 minutes. Appropriate 
corrections to maintain steady state combustion conditions must be made 
immediately either automatically or by the operator.

[[Page 462]]

Instruments which relate to combustion and emission control would 
normally include those measuring waste feed, auxiliary fuel feed, air 
flow, incinerator temperature, scrubber flow, scrubber pH, and relevant 
level controls.
    (b) The complete incinerator and associated equipment (pumps, 
valves, conveyors, pipes, etc.) must be inspected at least daily for 
leaks, spills, and fugitive emissions, and all emergency shutdown 
controls and system alarms must be checked to assure proper operation.

Sec. 265.351  Closure.

    At closure, the owner or operator must remove all hazardous waste 
and hazardous waste residues (including but not limited to ash, scrubber 
waters, and scrubber sludges) from the incinerator.

[Comment: At closure, as throughout the operating period, unless the 
owner or operator can demonstrate, in accordance with Sec. 261.3(d) of 
this chapter, that the residue removed from his incinerator is not a 
hazardous waste, the owner or operator becomes a generator of hazardous 
waste and must manage it in accordance with all applicable requirements 
of parts 262 through 266 of this chapter.]



Sec. 265.352  Interim status incinerators burning particular hazardous wastes.

    (a) Owners or operators of incinerators subject to this subpart may 
burn EPA Hazardous Wastes FO20, FO21, FO22, FO23, FO26, or FO27 if they 
receive a certification from the Assistant Administrator for Solid Waste 
and Emergency Response that they can meet the performance standards of 
subpart O of part 264 when they burn these wastes.
    (b) The following standards and procedures will be used in 
determining whether to certify an incinerator:
    (1) The owner or operator will submit an application to the 
Assistant Administrator for Solid Waste and Emergency Response 
containing applicable information in Secs. 270.19 and 270.62 
demonstrating that the incinerator can meet the performance standards in 
subpart O of part 264 when they burn these wastes.
    (2) The Assistant Administrator for Solid Waste and Emergency 
Response will issue a tentative decision as to whether the incinerator 
can meet the performance standards in subpart O of part 264. 
Notification of this tentative decision will be provided by newspaper 
advertisement and radio broadcast in the jurisdiction where the 
incinerator is located. The Assistant Administrator for Solid Waste and 
Emergency Response will accept comment on the tentative decision for 60 
days. The Assistant Administrator for Solid Waste and Emergency Response 
also may hold a public hearing upon request or at his discretion.
    (3) After the close of the public comment period, the Assistant 
Administrator for Solid Waste and Emergency Response will issue a 
decision whether or not to certify the incinerator.

    (a) The owner or operator must conduct, as a minimum, the following 
monitoring and inspections when thermally treating hazardous waste:
    (1) Existing instruments which relate to temperature and emission 
control (if an emission control device is present) must be monitored at 
least every 15 minutes. Appropriate corrections to maintain steady state 
or other appropriate thermal treatment conditions must be made 
immediately either automatically or by the operator. Instruments which 
relate to temperature and emission control would normally include those 
measuring waste feed, auxiliary fuel feed, treatment process 
temperature, and relevant process flow and level controls.
    (2) The stack plume (emissions), where present, must be observed 
visually at least hourly for normal appearance (color and opacity). The 
operator must immediately make any indicated operating corrections 
necessary to return any visible emissions to their normal appearance.
    (3) The complete thermal treatment process and associated equipment 
(pumps, valves, conveyors, pipes, etc.) must be inspected at least daily 
for leaks, spills, and fugitive emissions, and all emergency shutdown 
controls and system alarms must be checked to assure proper operation.

Sec. 265.381  Closure.

    At closure, the owner or operator must remove all hazardous waste 
and hazardous waste residues (including, but not limited to, ash) from 
the thermal treatment process or equipment.

[Comment: At closure, as throughout the operating period, unless the 
owner or operator can demonstrate, in accordance with Sec. 261.3 (c) or 
(d) of this chapter, that any solid waste removed from his thermal 
treatment process or equipment is not a hazardous waste, the owner or 
operator becomes a generator of hazardous waste and must manage it in 
accordance with all applicable requirements of parts 262, 263, and 265 
of this chapter.]



Sec. 265.382  Open burning; waste explosives.

    Open burning of hazardous waste is prohibited except for the open 
burning and detonation of waste explosives. Waste explosives include 
waste which has the potential to detonate and bulk military propellants 
which cannot safely be disposed of through other modes of treatment. 
Detonation is an explosion in which chemical transformation passes 
through the material faster than the speed of sound (0.33 kilometers/
second at sea level). Owners or operators choosing to open burn or 
detonate waste explosives must do so in accordance with the following 
table and in a manner that does not threaten human health or the 
environment.

Sec. 265.383  Interim status thermal treatment devices burning particular hazardous waste.

    (a) Owners or operators of thermal treatment devices subject to this 
subpart may burn EPA Hazardous Wastes FO20, FO21, FO22, FO23, FO26, or 
FO27 if they receive a certification from the Assistant Administrator 
for Solid Waste and Emergency Response that they can meet the 
performance standards of subpart O of part 264 when they burn these 
wastes.
    (b) The following standards and procedures will be used in 
determining whether to certify a thermal treatment unit:
    (1) The owner or operator will submit an application to the 
Assistant Administrator for Solid Waste and Emergency Response 
containing the applicable information in Secs. 270.19 and 270.62 
demonstrating that the thermal treatment unit can meet the performance 
standard in subpart O of part 264 when they burn these wastes.
    (2) The Assistant Administrator for Solid Waste and Emergency 
Response will issue a tentative decision as to whether the thermal 
treatment unit can meet the performance standards in subpart O of part 
264. Notification of this tentative decision will be provided by 
newspaper advertisement and radio broadcast in the jurisdiction where 
the thermal treatment device is located. The Assistant Administrator for 
Solid Waste and Emergency Response will accept comment on the tentative 
decision for 60 days. The Assistant Administrator for Solid Waste and 
Emergency Response also may hold a public hearing upon request or at his 
discretion.
    (3) After the close of the public comment period, the Assistant 
Administrator for Solid Waste and Emergency Response will issue a 
decision whether or not to certify the thermal treatment unit.

Sec. 265.442  Design and installation of new drip pads.

    Owners and operators of new drip pads must ensure that the pads are 
designed, installed, and operated in accordance with one of the 
following:
    (a) All of the applicable requirements of Secs. 265.443 (except 
Sec. 265.443(a)(4)), 265.444 and 265.445 of this subpart, or
    (b) All of the applicable requirements of Secs. 265.443 (except 
Sec. 265.443(b)), 265.444 and 265.445 of this subpart.

[57 FR 61504, Dec. 24, 1992]



Sec. 265.443  Design and operating requirements.

    (a) Drip pads must:
    (1) Be constructed of non-earthen materials, excluding wood and non-
structurally supported asphalt;
    (2) Be sloped to free-drain treated wood drippage, rain and other 
waters, or solutions of drippage and water or other wastes to the 
associated collection system;
    (3) Have a curb or berm around the perimeter;
    (4)(i) Have a hydraulic conductivity of less than or equal to 
1 x 10-7 centimeters per second, e.g., existing concrete drip 
pads must be sealed, coated, or covered with a surface material with a 
hydraulic conductivity of less than or equal to 1 x 10-7 
centimeters per second such that the entire surface where drippage 
occurs or may run across is capable of containing such drippage and 
mixtures of drippage and precipitation, materials, or other wastes while 
being routed to an associated collection system. This surface material 
must be maintained free of cracks and gaps that could adversely affect 
its hydraulic conductivity, and the material must be chemically 
compatible with the preservatives that contact the drip pad. The 
requirements of this provision apply only to existing drip pads and 
those drip pads for which the owner or operator elects to comply with 
Sec. 265.442(a) instead of Sec. 265.442(b).
    (ii) The owner or operator must obtain and keep on file at the 
facility a written assessment of the drip pad, reviewed and certified by 
an independent, qualified registered professional engineer that attests 
to the results of the evaluation. The assessment must be reviewed, 
updated and recertified annually. The evaluation must document the 
extent to which the drip pad meets the design and operating standards of 
this section, except for subsection (b).
    (5) Be of sufficient structural strength and thickness to prevent 
failure due to physical contact, climatic conditions, the stress of 
installation, and the stress of daily operations, e.g., variable and 
moving loads such as vehicle traffic, movement of wood, etc.

    Note: EPA will generally consider applicable standards established 
by professional organizations generally recognized by industry such as 
the American Concrete Institute (ACI) and the American Society of 
Testing Materials (ASTM) in judging the structural integrity requirement 
of this paragraph.

    (b) If an owner/operator elects to comply with Sec. 265.442(b) 
instead of Sec. 265.442(a), the drip pad must have:
    (1) A synthetic liner installed below the drip pad that is designed, 
constructed, and installed to prevent leakage from the drip pad into the 
adjacent subsurface soil or groundwater or surface water at any time 
during the active life (including the closure period) of the drip pad. 
The liner must be constructed of materials that will prevent waste from 
being absorbed into the liner and prevent releases into the adjacent 
subsurface soil or ground water or surface water during the active life 
of the facility. The liner must be:

[[Page 468]]

    (i) Constructed of materials that have appropriate chemical 
properties and sufficient strength and thickness to prevent failure due 
to pressure gradients (including static head and external hydrogeologic 
forces), physical contact with the waste or drip pad leakage to which 
they are exposed, climatic conditions, the stress of installation, and 
the stress of daily operation (including stresses from vehicular traffic 
on the drip pad);
    (ii) Placed upon a foundation or base capable of providing support 
to the liner and resistance to pressure gradients above and below the 
liner to prevent failure of the liner due to settlement, compression or 
uplift; and
    (iii) Installed to cover all surrounding earth that could come in 
contact with the waste or leakage; and
    (2) A leakage detection system immediately above the liner that is 
designed, constructed, maintained and operated to detect leakage from 
the drip pad. The leakage detection system must be:
    (i) Constructed of materials that are:
    (A) Chemically resistant to the waste managed in the drip pad and 
the leakage that might be generated; and
    (B) Of sufficient strength and thickness to prevent collapse under 
the pressures exerted by overlaying materials and by any equipment used 
at the drip pad; and
    (ii) Designed and operated to function without clogging through the 
scheduled closure of the drip pad.
    (iii) Designed so that it will detect the failure of the drip pad or 
the presence of a release of hazardous waste or accumulated liquid at 
the earliest practicable time.
    (3) A leakage collection system immediately above the liner that is 
designed, constructed, maintained and operated to collect leakage from 
the drip pad such that it can be removed from below the drip pad. The 
date, time, and quantity of any leakage collected in this system and 
removed must be documented in the operating log.
    (c) Drip pads must be maintained such that they remain free of 
cracks, gaps, corrosion, or other deterioration that could cause 
hazardous waste to be released from the drip pad.

    Note: See Sec. 265.443(m) for remedial action required if 
deterioration or leakage is detected.

    (d) The drip pad and associated collection system must be designed 
and operated to convey, drain, and collect liquid resulting from 
drippage or precipitation in order to prevent run-off.
    (e) Unless protected by a structure, as described in Sec. 265.440(b) 
of this subpart, the owner or operator must design, construct, operate 
and maintain a run-on control system capable of preventing flow onto the 
drip pad during peak discharge from at least a 24-hour, 25-year storm 
unless the system has sufficient excess capacity to contain any run-on 
that might enter the system, or the drip pad is protected by a structure 
or cover, as described in Sec. 265.440(b) of this subpart.
    (f) Unless protected by a structure or cover, as described in 
Sec. 265.440(b) of this subpart, the owner or operator must design, 
construct, operate and maintain a run-off management system to collect 
and control at least the water volume resulting from a 24-hour, 25-year 
storm.
    (g) The drip pad must be evaluated to determine that it meets the 
requirements of paragraphs (a) through (f) of this section and the owner 
or operator must obtain a statement from an independent, qualified 
registered professional engineer certifying that the drip pad design 
meets the requirements of this section.
    (h) Drippage and accumulated precipitation must be removed from the 
associated collection system as necessary to prevent overflow onto the 
drip pad.
    (i) The drip pad surface must be cleaned thoroughly in a manner and 
frequency such that accumulated residues of hazardous waste or other 
materials are removed, with residues being properly managed as hazardous 
waste, so as to allow weekly inspections of the entire drip pad surface 
without interference or hindrance from accumulated residues of hazardous 
waste or other materials on the drip pad. The owner or operator must 
document the date and time of each cleaning and the cleaning procedure 
used in the facility's operating log.

[[Page 469]]

    (j) Drip pads must be operated and maintained in a manner to 
minimize tracking of hazardous waste or hazardous waste constituents off 
the drip pad as a result of activities by personnel or equipment.
    (k) After being removed from the treatment vessel, treated wood from 
pressure and non-pressure processes must be held on the drip pad until 
drippage has ceased. The owner or operator must maintain records 
sufficient to document that all treated wood is held on the pad 
following treatment in accordance with this requirement.
    (l) Collection and holding units associated with run-on and run-off 
control systems must be emptied or otherwise managed as soon as possible 
after storms to maintain design capacity of the system.
    (m) Throughout the active life of the drip pad, if the owner or 
operator detects a condition that may have caused or has caused a 
release of hazardous waste, the condition must be repaired within a 
reasonably prompt period of time following discovery, in accordance with 
the following procedures:
    (1) Upon detection of a condition that may have caused or has caused 
a release of hazardous waste (e.g., upon detection of leakage by the 
leak detection system), the owner or operator must:
    (i) Enter a record of the discovery in the facility operating log;
    (ii) Immediately remove the portion of the drip pad affected by the 
condition from service;
    (iii) Determine what steps must be taken to repair the drip pad, 
remove any leakage from below the drip pad, and establish a schedule for 
accomplishing the clean up and repairs;
    (iv) Within 24 hours after discovery of the condition, notify the 
Regional Administrator of the condition and, within 10 working days, 
provide a written notice to the Regional Administrator with a 
description of the steps that will be taken to repair the drip pad, and 
clean up any leakage, and the schedule for accomplishing this work.
    (2) The Regional Administrator will review the information 
submitted, make a determination regarding whether the pad must be 
removed from service completely or partially until repairs and clean up 
are complete, and notify the owner or operator of the determination and 
the underlying rationale in writing.
    (3) Upon completing all repairs and clean up, the owner or operator 
must notify the Regional Administrator in writing and provide a 
certification, signed by an independent qualified, registered 
professional engineer, that the repairs and clean up have been completed 
according to the written plan submitted in accordance with paragraph 
(m)(1)(iv) of this section.
    (n) The owner or operator must maintain, as part of the facility 
operating log, documentation of past operating and waste handling 
practices. This must include identification of preservative formulations 
used in the past, a description of drippage management practices, and a 
description of treated wood storage and handling practices.

Sec. 265.444  Inspections.

    (a) During construction or installation, liners and cover systems 
(e.g., membranes, sheets, or coatings) must be inspected for uniformity, 
damage, and imperfections (e.g., holes, cracks, thin spots, or foreign 
materials). Immediately after construction or installation, liners must 
be inspected and certified as meeting the requirements of Sec. 265.443 
of this subpart by an independent qualified, registered professional 
engineer. The certification must be maintained at the facility as part 
of the facility operating record. After installation liners and covers 
must be inspected to ensure tight seams and joints and the absence of 
tears, punctures, or blisters.
    (b) While a drip pad is in operation, it must be inspected weekly 
and after storms to detect evidence of any of the following:
    (1) Deterioration, malfunctions or improper operation of run-on and 
run-off control systems;
    (2) The presence of leakage in and proper functioning of leakage 
detection system.
    (3) Deterioration or cracking of the drip pad surface.


[[Page 470]]


    Note: See Sec. 265.443(m) for remedial action required if 
deterioration or leakage is detected.



Sec. 265.445  Closure.

    (a) At closure, the owner or operator must remove or decontaminate 
all waste residues, contaminated containment system components (pad, 
liners, etc.), contaminated subsoils, and structures and equipment 
contaminated with waste and leakage, and manage them as hazardous waste.
    (b) If, after removing or decontaminating all residues and making 
all reasonable efforts to effect removal or decontamination of 
contaminated components, subsoils, structures, and equipment as required 
in paragraph (a) of this section, the owner or operator finds that not 
all contaminated subsoils can be practically removed or decontaminated, 
he must close the facility and perform post/closure care in accordance 
with closure and post-closure care requirements that apply to landfills

Sec. 265.1032  Standards: Process vents.

    (a) The owner or operator of a facility with process vents 
associated with distillation, fractionation, thin-film evaporation, 
solvent extraction or air or steam stripping operations managing 
hazardous wastes with organic concentrations at least 10 ppmw shall 
either:
    (1) Reduce total organic emissions from all affected process vents 
at the facility below 1.4 kg/h (3 lb/h) and 2.8 Mg/yr (3.1 tons/yr), or
    (2) Reduce, by use of a control device, total organic emissions from 
all affected process vents at the facility by 95 weight percent.
    (b) If the owner or operator installs a closed-vent system and 
control device to comply with the provisions of paragraph (a) of this 
section, the closed-vent system and control device must meet the 
requirements of Sec. 265.1033.
    (c) Determinations of vent emissions and emission reductions or 
total organic compound concentrations achieved by add-on control devices 
may be based on engineering calculations or performance tests. If 
performance tests are used to determine vent emissions, emission 
reductions, or total organic compound concentrations achieved by add-on 
control devices, the performance tests must conform with the 
requirements of Sec. 265.1034(c).
    (d) When an owner or operator and the Regional Administrator do not 
agree on determinations of vent emissions and/or emission reductions or 
total organic compound concentrations achieved by add-on control devices 
based on engineering calculations, the test methods in Sec. 265.1034(c) 
shall be used to resolve the disagreement.



Sec. 265.1033  Standards: Closed-vent systems and control devices.

    (a)(1) Owners or operators of closed-vent systems and control 
devices used to comply with provisions of this part shall comply with 
the provisions of this section.

this subpart on the effective date that the facility becomes subject to 
the provisions of this subpart must prepare an implementation schedule 
that includes dates by which the closed-vent system and control device 
will be installed and in operation. The controls must be installed as 
soon as possible, but the implementation schedule may allow up to 30 
months after the effective date that the facility becomes subject to 
this subpart for installation and startup. All units that begin 
operation after December 21, 1990 must comply with the rules immediately 
(i.e., must have control devices installed and operating on startup of 
the affected unit); the 2-year implementation schedule does not apply to 
these units.
    (b) A control device involving vapor recovery (e.g., a condenser or 
adsorber) shall be designed and operated to recover the organic vapors 
vented to it with an efficiency of 95 weight percent or greater unless 
the total organic emission limits of Sec. 265.1032(a)(1) for all

weight percent.
    (c) An enclosed combustion device (e.g., a vapor incinerator, 
boiler, or process heater) shall be designed and operated to reduce the 
organic emissions vented to it by 95 weight percent or greater; to 
achieve a total organic compound concentration of 20 ppmv, expressed as 
the sum of the actual compounds, not carbon equivalents, on a dry basis 
corrected to 3 percent oxygen; or to provide a minimum residence time of 
0.50 seconds at a minimum temperature of 760  deg.C. If a boiler or 
process heater is used as the control device, then the vent stream shall 
be introduced into the flame combustion zone of the boiler or process 
heater.
    (d)(1) A flare shall be designed for and operated with no visible 
emissions as determined by the methods specified in paragraph (e)(1) of

    (3) A flare shall be used only if the net heating value of the gas 
being combusted is 11.2 MJ/scm (300 Btu/scf) or greater, if the flare is 
steam-assisted or air-assisted; or if the net heating value

[[Page 472]]

of the gas being combusted is 7.45 MJ/scm (200 Btu/scf) or greater if 
the flare is nonassisted. The net heating value of the gas being 
combusted shall be determined by the methods specified in paragraph 
(e)(2) of this section.

value of the gas being combusted is greater than 37.3 MJ/scm (1,000 Btu/
scf).
    (iii) A steam-assisted or nonassisted flare designed for and 
operated with an exit velocity, as determined by the methods specified 
in paragraph (e)(3) of this section, less than the velocity, 
Vmax, as determined by the method specified in paragraph 
(e)(4) of this section, and less than 122 m/s (400 ft/s) is allowed.
    (5) An air-assisted flare shall be designed and operated with an 
exit velocity less than the velocity, Vmax, as determined by 
the method specified in paragraph (e)(5) of this section.

    (iv) Total organic mass flow rates shall be determined by the 
following equation:

                                                                                                                                                        
                                                                         n                                                                              
                                                                                                                                                        
                                                  Eh=Qsd   <3-ln [>      CiMWi   <3-ln ]>   [0.0416] [10-6]                                    
                                                                                                                                                        
                                                                        i=1                                                                             
                                                                                                                                                        
                                                                                                                                                        
                                                                                                                                                        

where:

Eh=Total organic mass flow rate, kg/h;
Qsd=Volumetric flow rate of gases entering or exiting control 
          device, as determined by Method 2, dscm/h;

[[Page 477]]

n=Number of organic compounds in the vent gas;
Ci=Organic concentration in ppm, dry basis, of compound i in 
          the vent gas, as determined by Method 18;
MWi=Molecular weight of organic compound i in the vent gas, 
          kg/kg-mol;
0.0416=Conversion factor for molar volume, kg-mol/m3 (@ 293 K 
          and 760 mm Hg);
10-6=Conversion from ppm, ppm-1.

    (v) The annual total organic emission rate shall be determined by 
the following equation:

EA=(Eh) (H)

where:

EA=Total organic mass emission rate, kg/y;
Eh=Total organic mass flow rate for the process vent, kg/h;
H=Total annual hours of operations for the affected unit, h.

    (vi) Total organic emissions from all affected process vents at the 
facility shall be determined by summing the hourly total organic mass 
emission rates (Eh, as determined in paragraph (c)(1)(iv) of 
this section) and by summing the annual total organic mass emission 
rates (EA, as determined in paragraph (c)(1)(v) of this 
section) for all affected process vents at the facility.
    (2) The owner or operator shall record such process information as 
may be necessary to determine the conditions of the performance tests. 
Operations during periods of startup, shutdown, and malfunction shall 
not constitute representative conditions for the purpose of a 
performance test.
    (3) The owner or operator of an affected facility shall provide, or 
cause to be provided, performance testing facilities as follows:
    (i) Sampling ports adequate for the test methods specified in 
paragraph (c)(1) of this section.
    (ii) Safe sampling platform(s).
    (iii) Safe access to sampling platform(s).
    (iv) Utilities for sampling and testing equipment.
    (4) For the purpose of making compliance determinations, the time-
weighted average of the results of the three runs shall apply. In the 
event that a sample is accidentally lost or conditions occur in which 
one of the three runs must be discontinued because of forced shutdown, 
failure of an irreplaceable portion of the sample train, extreme 
meteorological conditions, or other circumstances beyond the owner or 
operator's control, compliance may, upon the Regional Administrator's 
approval, be determined using the average of the results of the two 
other runs.
    (d) To show that a process vent associated with a hazardous waste 
distillation, fractionation, thin-film evaporation, solvent extraction, 
or air or steam stripping operation is not subject to the requirements 
of this subpart, the owner or operator must make an initial 
determination that the time-weighted, annual average total organic 
concentration of the waste managed by the waste management unit is less 
than 10 ppmw using one of the following two methods:
    (1) Direct measurement of the organic concentration of the waste 
using the following procedures:
    (i) The owner or operator must take a minimum of four grab samples 
of waste for each waste stream managed in the affected unit under 
process conditions expected to cause the maximum waste organic 
concentration.
    (ii) For waste generated onsite, the grab samples must be collected 
at a point before the waste is exposed to the atmosphere such as in an 
enclosed pipe or other closed system that is used to transfer the waste 
after generation to the first affected distillation fractionation, thin-
film evaporation, solvent extraction, or air or steam stripping 
operation. For waste generated offsite, the grab samples must be 
collected at the inlet to the first waste management unit that receives 
the waste provided the waste has been transferred to the facility in a 
closed system such as a tank truck and the waste is not diluted or mixed 
with other waste.
    (iii) Each sample shall be analyzed and the total organic 
concentration of the sample shall be computed using Method 9060 or 8260 
of SW-846 (incorporated by reference under Sec. 260.11).
    (iv) The arithmetic mean of the results of the analyses of the four 
samples shall apply for each waste stream managed in the unit in 
determining the time-weighted, annual average total organic 
concentration of the waste. The time-weighted average is to be 
calculated using the annual quantity of each waste stream processed and 
the

[[Page 478]]

mean organic concentration of each waste stream managed in the unit.
    (2) Using knowledge of the waste to determine that its total organic 
concentration is less than 10 ppmw. Documentation of the waste 
determination is required. Examples of documentation that shall be used 
to support a determination under this provision include production 
process information documenting that no organic compounds are used, 
information that the waste is generated by a process that is identical 
to a process at the same or another facility that has previously been 
demonstrated by direct measurement to generate a waste stream having a 
total organic content less than 10 ppmw, or prior speciation analysis 
results on the same waste stream where it can also be documented that no 
process changes have occurred since that analysis that could affect the 
waste total organic concentration.
    (e) The determination that distillation fractionation, thin-film 
evaporation, solvent extraction, or air or steam stripping operations 
manage hazardous wastes with time-weighted annual average total organic 
concentrations less than 10 ppmw shall be made as follows:
    (1) By the effective date that the facility becomes subject to the 
provisions of this subpart or by the date when the waste is first 
managed in a waste management unit, whichever is later; and
    (2) For continuously generated waste, annually; or
    (3) Whenever there is a change in the waste being managed or a 
change in the process that generates or treats the waste.
    (f) When an owner or operator and the Regional Administrator do not 
agree on whether a distillation, fractionation, thin-film evaporation, 
solvent extraction, or air or steam stripping operation manages a 
hazardous waste with organic concentrations of at least 10 ppmw based on 
knowledge of the waste, the procedures in Method 8260 of SW-846 
(incorporated by reference under Sec. 260.11) may be used to resolve the 
dispute.

Sec. 265.1035  Recordkeeping requirements.

    (a)(1) Each owner or operator subject to the provisions of this 
subpart shall comply with the recordkeeping requirements of this 
section.
    (2) An owner or operator of more than one hazardous waste management 
unit subject to the provisions of this subpart may comply with the 
recordkeeping requirements for these hazardous waste management units in 
one recordkeeping system if the system identifies each record by each 
hazardous waste management unit.
    (b) Owners and operators must record the following information in 
the facility operating record:
    (1) For facilities that comply with the provisions of 
Sec. 265.1033(a)(2), an implementation schedule that includes dates by 
which the closed-vent system and control device will be installed and in 
operation. The schedule must also include a rationale of why the 
installation cannot be completed at an earlier date. The implementation 
schedule must be in the facility operating record by the effective date 
that the facility becomes subject to the provisions of this subpart.
    (2) Up-to-date documentation of compliance with the process vent 
standards in Sec. 265.1032. including:
    (i) Information and data identifying all affected process vents, 
annual throughput end operating hours of each affected unit, estimated 
emission rates for each affected vent and for the overall facility 
(i.e., the total emissions for all affected vents at the facility), and 
the approximate location within the facility of each affected unit 
(e.g., identify the hazardous waste management units on a facility plot 
plan); and
    (ii) Information and data supporting determinations of vent 
emissions and emission reductions achieved by add-on control devices 
based on engineering calculations or source tests. For the purpose of 
determining compliance, determinations of vent emissions and emission 
reductions must be made using operating parameter values (e.g., 
temperatures, flow rates or vent stream organic compounds and 
concentrations) that represent the conditions that result in maximum 
organic emissions, such as when the waste

[[Page 479]]

management unit is operating at the highest load or capacity level 
reasonably expected to occur. If the owner or operator takes any action 
(e.g., managing a waste of different composition or increasing operating 
hours of affected waste management units) that would result in an 
increase in total organic emissions from affected process vents at the 
facility, then a new determination is required.
    (3) Where an owner or operator chooses to use test data to determine 
the organic removal efficiency or total organic compound concentration 
achieved by the control device, a performance test plan. The test plan 
must include:
    (i) A description of how it is determined that the planned test is 
going to be conducted when the hazardous waste management unit is 
operating at the highest load or capacity level reasonably expected to 
occur. This shall include the estimated or design flow rate and organic

    (D) Capacity.
    (E) Construction materials.
    (iii) A detailed description of sampling and monitoring procedures, 
including sampling and monitoring locations in the system, the equipment 
to be used, sampling and monitoring frequency, and planned analytical 
procedures for sample analysis.
    (4) Documentation of compliance with Sec. 265.1033 shall include the 
following information:
    (i) A list of all information references and sources used in 
preparing the documentation.
    (ii) Records, including the dates, of each compliance test required 
by Sec. 265.1033(j).

specifications, drawings, schematics, and piping and instrumentation 
diagrams based on the appropriate sections of ``APTI Course 415: Control 
of Gaseous Emissions'' (incorporated by reference as specified in 
Sec. 260.11) or other engineering texts acceptable to the Regional 
Administrator that present basic control device design information. 
Documentation provided by the control device manufacturer or vendor that

composition, constituent concentrations, and flow rate. The design 
analysis shall also consider the requirements specified in 
Sec. 265.1033(d).

Sec. 260.11); or
    (3) Application of the knowledge of the nature of the hazardous 
waste stream or the process by which it was produced. Documentation of a 
waste determination by knowledge is required. Examples of documentation 
that shall be used to support a determination under this provision 
include production process information documenting that no organic 
compounds are used, information that the waste is generated by a process 
that is identical to a process at the same or another facility that has 
previously been demonstrated by direct measurement to have a total 
organic content less than 10 percent, or prior speciation analysis 
results on the same waste stream where it can also be documented that no 
process changes have occurred since that analysis that could affect the 
waste total organic concentration.
    (e) If an owner or operator determines that a piece of equipment 
contains or contacts a hazardous waste with organic concentrations at 
least 10 percent by weight, the determination

[[Page 489]]

can be revised only after following the procedures in paragraph (d)(1) 
or (d)(2) of this section.
    (f) When an owner or operator and the Regional Administrator do not 
agree on whether a piece of equipment contains or contacts a hazardous 
waste with organic concentrations at least 10 percent by weight, the 
procedures in paragraph (d)(1) or (d)(2) of this section can be used to 
resolve the dispute.
    (g) Samples used in determining the percent organic content shall be

Sec. 265.1081  Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given to them in the Act and parts 260 through 266 of this 
chapter.
    Average volatile organic concentration or average VO concentration 
means the mass-weighted average volatile organic concentration of a 
hazardous waste as determined in accordance with the requirements of 
Sec. 265.1084 of this subpart.

[[Page 493]]

    Closure device means a cap, hatch, lid, plug, seal, valve, or other 
type of fitting that blocks an opening in a cover such that when the 
device is secured in the closed position it prevents or reduces air 
pollutant emissions to the atmosphere. Closure devices include devices 
that are detachable from the cover (e.g., a sampling port cap), manually 
operated (e.g., a hinged access lid or hatch), or automatically operated 
(e.g., a spring-loaded pressure relief valve).
    Continuous seal means a seal that forms a continuous closure that 
completely covers the space between the edge of the floating roof and 
the wall of a tank. A continuous seal may be a vapor-mounted seal, 
liquid-mounted seal, or metallic shoe seal. A continuous seal may be 
constructed of fastened segments so as to form a continuous seal.
    Cover means a device that provides a continuous barrier over the 
hazardous waste managed in a unit to prevent or reduce air pollutant 
emissions to the atmosphere. A cover may have openings (such as access 
hatches, sampling ports, gauge wells) that are necessary for operation, 
inspection, maintenance, and repair of the unit on which the cover is 
used. A cover may be a separate piece of equipment which can be detached 
and removed from the unit or a cover may be formed by structural 
features permanently integrated into the design of the unit.
    Enclosure means a structure that surrounds a tank or container, 
captures organic vapors emitted from the tank or container, and vents 
the captured vapors through a closed-vent system to a control device.
    External floating roof means a pontoon-type or double-deck type 
cover that rests on the surface of the material managed in a tank with 
no fixed roof.
    Fixed roof means a cover that is mounted on a unit in a stationary 
position and does not move with fluctuations in the level of the 
material managed in the unit.
    Floating membrane cover means a cover consisting of a synthetic 
flexible membrane material that rests upon and is supported by the 
hazardous waste being managed in a surface impoundment.
    Floating roof means a cover consisting of a double deck, pontoon 
single deck, or internal floating cover which rests upon and is 
supported by the material being contained, and is equipped with a 
continuous seal.
    Hard-piping means pipe or tubing that is manufactured and properly 
installed in accordance with relevant standards and good engineering 
practices.
    In light material service means the container is used to manage a 
material for which both of the following conditions apply: the vapor 
pressure of one or more of the organic constituents in the material is 
greater than 0.3 kilopascals (kPa) at 20  deg.C; and the total 
concentration of the pure organic constituents having a vapor pressure 
greater than 0.3 kPa at 20  deg.C is equal to or greater than 20 percent 
by weight.
    Internal floating roof means a cover that rests or floats on the 
material surface (but not necessarily in complete contact with it) 
inside a tank that has a fixed roof.
    Liquid-mounted seal means a foam or liquid-filled primary seal 
mounted in contact with the hazardous waste between the tank wall and 
the floating roof continuously around the circumference of the tank.
    Malfunction means any sudden, infrequent, and not reasonably 
preventable failure of air pollution control equipment, process 
equipment, or a process to operate in a normal or usual manner. Failures 
that are caused in part by poor maintenance or careless operation are 
not malfunctions.
    Maximum organic vapor pressure means the sum of the individual 
organic constituent partial pressures exerted by the material contained 
in a tank, at the maximum vapor pressure-causing conditions (i.e., 
temperature, agitation, pH effects of combining wastes, etc.) reasonably 
expected to occur in the tank. For the purpose of this subpart, maximum 
organic vapor pressure is determined using the procedures specified in 
Sec. 265.1084(c) of this subpart.
    Metallic shoe seal means a continuous seal that is constructed of 
metal sheets which are held vertically against the

[[Page 494]]

wall of the tank by springs, weighted levers, or other mechanisms and is 
connected to the floating roof by braces or other means. A flexible 
coated fabric (envelope) spans the annular space between the metal sheet 
and the floating roof.
    No detectable organic emissions means no escape of organics to the 
atmosphere as determined using the procedure specified in 
Sec. 265.1084(d) of this subpart.
    Point of waste origination means as follows:
    (1) When the facility owner or operator is the generator of the 
hazardous waste, the point of waste origination means the point where a 
solid waste produced by a system, process, or waste management unit is 
determined to be a hazardous waste as defined in 40 CFR part 261.

    [Note: In this case, this term is being used in a manner similar to 
the use of the term ``point of generation'' in air standards established 
for waste management operations under authority of the Clean Air Act in 
40 CFR parts 60, 61, and 63.]

    (2) When the facility owner and operator are not the generator of 
the hazardous waste, point of waste origination means the point where 
the owner or operator accepts delivery or takes possession of the 
hazardous waste.
    Point of waste treatment means the point where a hazardous waste to 
be treated in accordance with Sec. 265.1083(c)(2) of this subpart exits 
the treatment process. Any waste determination shall be made before the 
waste is conveyed, handled, or otherwise managed in a manner that allows 
the waste to volatilize to the atmosphere.
    Safety device means a closure device such as a pressure relief 
valve, frangible disc, fusible plug, or any other type of device which 
functions exclusively to prevent physical damage or permanent 
deformation to a unit or its air emission control equipment by venting 
gases or vapors directly to the atmosphere during unsafe conditions 
resulting from an unplanned, accidental, or emergency event. For the 
purpose of this subpart, a safety device is not used for routine venting 
of gases or vapors from the vapor headspace underneath a cover such as 
during filling of the unit or to adjust the pressure in this vapor 
headspace in response to normal daily diurnal ambient temperature 
fluctuations. A safety device is designed to remain in a closed position 
during normal operations and open only when the internal pressure, or 
another relevant parameter, exceeds the device threshold setting 
applicable to the air emission control equipment as determined by the 
owner or operator based on manufacturer recommendations, applicable 
regulations, fire protection and prevention codes, standard engineering 
codes and practices, or other requirements for the safe handling of 
flammable, ignitable, explosive, reactive, or hazardous materials.
    Single-seal system means a floating roof having one continuous seal. 
This seal may be vapor-mounted, liquid-mounted, or a metallic shoe seal.
    Vapor-mounted seal means a continuous seal that is mounted such that 
there is a vapor space between the hazardous waste in the unit and the 
bottom of the seal.
    Volatile organic concentration or VO concentration means the 
fraction by weight of the volatile organic compounds contained in a 
hazardous waste expressed in terms of parts per million (ppmw) as 
determined by direct measurement or by knowledge of the waste in 
accordance with the requirements of Sec. 265.1084 of this subpart. For 
the purpose of determining the VO concentration of a hazardous waste, 
organic compounds with a Henry's law constant value of at least 0.1 
mole-fraction-in-the-gas-phase/mole-fraction-in the liquid-phase (0.1 Y/
X) (which can also be expressed as 1.8 x 10-\6\ atmospheres/
gram-mole/m\3\) at 25 degrees Celsius must be included. Appendix VI of 
this subpart presents a list of compounds known to have a Henry's law 
constant value less than the cutoff level.
    Waste determination means performing all applicable procedures in 
accordance with the requirements of Sec. 265.1084 of this subpart to 
determine whether a hazardous waste meets standards specified in this 
subpart. Examples of a waste determination include performing the 
procedures in accordance with the requirements of Sec. 265.1084 of this 
subpart to determine the average VO concentration of a hazardous waste 
at

[[Page 495]]

the point of waste origination; the average VO concentration of a 
hazardous waste at the point of waste treatment and comparing the 
results to the exit concentration limit specified for the process used 
to treat the hazardous waste; the organic reduction efficiency and the 
organic biodegradation efficiency for a biological process used to treat 
a hazardous waste and comparing the results to the applicable standards; 
or the maximum volatile organic vapor pressure for a hazardous waste in 
a tank and comparing the results to the applicable standards.
    Waste stabilization process means any physical or chemical process 
used to either reduce the mobility of hazardous constituents in a 
hazardous waste or eliminate free liquids as determined by Test Method 
9095 (Paint Filter Liquids Test) in ``Test Methods for Evaluating Solid 
Waste, Physical/Chemical Methods,'' EPA Publication No. SW-846, Third 
Edition, September 1986, as amended by Update I, November 15, 1992 
(incorporated by reference--refer to Sec. 260.11 of this chapter). A 
waste stabilization process includes mixing the hazardous waste with 
binders or other materials, and curing the resulting hazardous waste and 
binder mixture. Other synonymous terms used to refer to this process are 
``waste fixation'' or ``waste solidification.'' This does not include 
the adding of absorbent materials to the surface of a waste, without 
mixing, agitation, or subsequent curing, to absorb free liquid.

enter and maintain the implementation schedule specified in paragraph 
(a)(2)(ii) of this section in a permanent, readily available file 
located at the facility site no later than the effective date of the 
amendment. I11(c) The Regional Administrator may elect to extend the 
implementation date for control equipment at a facility, on a case by 
case basis, to a date later than December 8, 1997, when special 
circumstances that are beyond the facility owner's or operator's control 
delay installation or operation of control equipment and the owner or 
operator has made all reasonable and prudent attempts to comply with the 
requirements of this subpart.

tanks, surface impoundments, and containers subject to this subpart.
    (b) The owner or operator shall control air pollutant emissions from 
each waste management unit in accordance with standards specified in 
Sec. 265.1085 through Sec. 265.1088 of this subpart, as applicable to 
the waste management unit, except as provided for in paragraph (c) of 
this section.
    (c) A tank, surface impoundment, or container is exempt from 
standards specified in Sec. 265.1085 through Sec. 265.1088 of this 
subpart, as applicable, provided that the waste management unit is one 
of the following:
    (1) A tank, surface impoundment, or container for which all 
hazardous waste entering the unit has an average VO concentration at the 
point of waste origination of less than 500 parts per million by weight 
(ppmw). The average VO concentration shall be determined using the 
procedures specified in Sec. 265.1084(a) of this subpart. The owner or 
operator shall review and update, as necessary, this determination at 
least once every 12 months following the date of the initial 
determination for the hazardous waste streams entering the unit.
    (2) A tank, surface impoundment, or container for which the organic 
content of all the hazardous waste entering the waste management unit 
has been reduced by an organic destruction or removal process that 
achieves any one of the following conditions:
    (i) A process that removes or destroys the organics contained in the 
hazardous waste to a level such that the average VO concentration of the 
hazardous waste at the point of waste treatment is less than the exit 
concentration limit (Ct) established for the process. The 
average VO concentration of the hazardous waste at the point of waste 
treatment and the exit concentration limit for the process shall be 
determined using the procedures specified in Sec. 265.1084(b) of this 
subpart.
    (ii) A process that removes or destroys the organics contained in

(MRbio) for all hazardous waste treated by the process is 
equal to or greater than the required organic mass removal rate (RMR). 
The required organic mass removal rate and the actual organic mass 
biodegradation rate for the process shall be determined using the 
procedures specified in Sec. 265.1084(b) of this subpart.
    (v) A process that removes or destroys the organics contained in the 
hazardous waste and meets all of the following conditions:

hazardous waste enters the treatment process, the hazardous waste is 
managed continuously in waste management units which use air emission 
controls in accordance with the standards specified in Sec. 265.1085 
through Sec. 265.1088 of this subpart, as applicable to the waste 
management unit.
    (B) From the point of waste origination through the point where the 
hazardous waste enters the treatment process, any transfer of the 
hazardous waste is accomplished through continuous hard-piping or other 
closed system transfer that does not allow exposure of the waste to the 
atmosphere. The EPA considers a drain system that meets the requirements 
of 40 CFR part 63, subpart RR--National Emission Standards for 
Individual Drain Systems to be a closed system.
    (C) The average VO concentration of the hazardous waste at the point 
of waste treatment is less than the lowest average VO concentration at 
the point of waste origination determined for each of the individual 
waste streams entering the process or 500 ppmw, whichever value is 
lower. The average VO concentration of each individual waste stream at 
the point of waste origination shall be determined using the procedures 
specified in Sec. 265.1084(a) of this subpart. The average VO 
concentration of the hazardous waste at the point of waste treatment

efficiency (R) for the process is equal to or greater than 95 percent 
and the owner or operator certifies that the average VO concentration at 
the point of waste origination for each of the individual waste streams 
entering the process is less than 10,000 ppmw. The organic reduction 
efficiency for the process and the average VO concentration of the 
hazardous waste at the point of waste origination shall be determined 
using the procedures specified in Sec. 265.1084(b) and Sec. 265.1084(a) 
of this subpart, respectively.
    (vii) A hazardous waste incinerator for which the owner or operator 
has either:
    (A) Been issued a final permit under 40 CFR part 270 which 
implements the requirements of 40 CFR part 264, subpart O; or
    (B) Has designed and operates the incinerator in accordance with the 
interim status requirements of subpart O of this part.
    (viii) A boiler or industrial furnace for which the owner or 
operator has either:
    (A) Been issued a final permit under 40 CFR part 270 which 
implements the requirements of 40 CFR part 266, subpart H, or
    (B) Has designed and operates the boiler or industrial furnace in 
accordance with the interim status requirements of 40 CFR part 266, 
subpart H.
    (ix) For the purpose of determining the performance of an organic 
destruction or removal process in accordance with the conditions in each 
of paragraphs (c)(2)(i) through (c)(2)(vi) of this section, the owner or 
operator shall account for VO concentrations determined to be below the 
limit of detection of the analytical method by using the following VO 
concentration:
    (A) If Method 25D in 40 CFR part 60, appendix A is used for the 
analysis, one-half the blank value determined in the method.
    (B) If any other analytical method is used, one-half the limit of 
detection established for the method.
    (3) A tank used for biological treatment of hazardous waste in 
accordance with the requirements of paragraph (c)(2)(iv) of this 
section.
    (4) A tank, surface impoundment, or container for which all 
hazardous waste placed in the unit either:

[[Page 498]]

    (i) Meets the numerical concentration limits for organic hazardous 
constituents, applicable to the hazardous waste, as specified in 40 CFR 
part 268--Land Disposal Restrictions under Table ``Treatment Standards 
for Hazardous Waste'' in 40 CFR 268.40; or
    (ii) Has been treated by the treatment technology established by EPA 
for the waste in 40 CFR 268.42(a), or treated by an equivalent method of 
treatment approved by EPA pursuant to 40 CFR 268.42(b).
    (5) A tank used for bulk feed of hazardous waste to a waste 
incinerator and all of the following conditions are met:
    (i) The tank is located inside an enclosure vented to a control 
device that is designed and operated in accordance with all applicable 
requirements specified under 40 CFR part 61, subpart FF--National 
Emission Standards for Benzene Waste Operations for a facility at which 
the total annual benzene quantity from the facility waste is equal to or 
greater than 10 megagrams per year;
    (ii) The enclosure and control device serving the tank were 
installed and began operation prior to November 25, 1996; and
    (iii) The enclosure is designed and operated in accordance with the 
criteria for a permanent total enclosure as specified in ``Procedure T--
Criteria for and Verification of a Permanent or Temporary Total 
Enclosure'' under 40 CFR 52.741, Appendix B. The enclosure may have 
permanent or temporary openings to allow worker access; passage of 
material into or out of the enclosure by conveyor, vehicles, or other 
mechanical or electrical equipment; or to direct air flow into the 
enclosure. The owner or operator shall perform the verification 
procedure for the enclosure as specified in Section 5.0 to ``Procedure 
T--Criteria for and Verification of a Permanent or Temporary Total 
Enclosure'' annually.
    (d) The Regional Administrator may at any time perform or request 
that the owner or operator perform a waste determination for a hazardous 
waste managed in a tank, surface impoundment, or container exempted from 
using air emission controls under the provisions of this section as 
follows:
    (1) The waste determination for average VO concentration of a 
hazardous waste at the point of waste origination shall be performed 
using direct measurement in accordance with the applicable requirements 
of Sec. 265.1084(a) of this subpart. The waste determination for a 
hazardous waste at the point of waste treatment shall be performed in 
accordance with the applicable requirements of Sec. 265.1084(b) of this 
subpart.
    (2) In performing a waste determination pursuant to paragraph (d)(1) 
of this section, the sample preparation and analysis shall be conducted 
as follows:
    (i) In accordance with the method used by the owner or operator to 
perform the waste analysis, except in the case specified in paragraph 
(d)(2)(ii) of this section.
    (ii) If the Regional Administrator determines that the method used 
by the owner or operator was not appropriate for the hazardous waste 
managed in the tank, surface impoundment, or container, then the 
Regional Administrator may choose an appropriate method.
    (3) In a case when the owner or operator is requested to perform the 
waste determination, the Regional Administrator may elect to have an 
authorized representative observe the collection of the hazardous waste 
samples used for the analysis.
    (4) In a case when the results of the waste determination performed 
or requested by the Regional Administrator do not agree with the results 
of a waste determination performed by the owner or operator using 
knowledge of the waste, then the results of the waste determination 
performed in accordance with the requirements of paragraph (d)(1) of 
this section shall be used to establish compliance with the requirements 
of this subpart.
    (5) In a case when the owner or operator has used an averaging 
period greater than 1 hour for determining the average VO concentration 
of a hazardous waste at the point of waste origination, the Regional 
Administrator may elect to establish compliance with this subpart by 
performing or requesting that the owner or operator perform a waste

[[Page 499]]

determination using direct measurement based on waste samples collected 
within a 1-hour period as follows:
    (i) The average VO concentration of the hazardous waste at the point 
of waste origination shall be determined by direct measurement in 
accordance with the requirements of Sec. 265.1084(a) of this subpart.
    (ii) Results of the waste determination performed or requested by 
the Regional Administrator showing that the average VO concentration of 
the hazardous waste at the point of waste origination is equal to or 
greater than 500 ppmw shall constitute noncompliance with this subpart 
except in a case as provided for in paragraph (d)(5)(iii) of this 
section.
    (iii) For the case when the average VO concentration of the 
hazardous waste at the point of waste origination previously has been 
determined by the owner or operator using an averaging period greater 
than 1 hour to be less than 500 ppmw but because of normal operating 
process variations the VO concentration of the hazardous waste 
determined by direct measurement for any given 1-hour period may be 
equal to or greater than 500 ppmw, information that was used by the 
owner or operator to determine the average VO concentration of the 
hazardous waste (e.g., test results, measurements, calculations, and 
other documentation) and recorded in the facility records in accordance 
with the requirements of Sec. 265.1084(a) and Sec. 265.1090 of this 
subpart shall be considered by the Regional Administrator together with 
the results of the waste determination performed or requested by the 
Regional Administrator in establishing compliance with this subpart.

Sec. 265.1084  Waste determination procedures.

    (a) Waste determination procedure to determine average volatile 
organic (VO) concentration of a hazardous waste at the point of waste 
origination.
    (1) An owner or operator shall determine the average VO 
concentration at the point of waste origination for each hazardous waste 
placed in a waste management unit exempted under the provisions of 
Sec. 265.1083(c)(1) of this subpart from using air emission controls in 
accordance with standards specified in Sec. 265.1085 through 
Sec. 265.1088 of this subpart, as applicable to the waste management 
unit.
    (2) The average VO concentration of a hazardous waste at the point 
of waste origination shall be determined using either direct measurement 
as specified in paragraph (a)(3) of this section or by knowledge as 
specified in paragraph (a)(4) of this section.
    (3) Direct measurement to determine average VO concentration of a 
hazardous waste at the point of waste origination.
    (i) Identification. The owner or operator shall identify and record 
the point of waste origination for the hazardous waste.
    (ii) Sampling. Samples of the hazardous waste stream shall be 
collected at the point of waste origination in a manner such that 
volatilization of organics contained in the waste and in the subsequent 
sample is minimized and an adequately representative sample is collected 
and maintained for analysis by the selected method.
    (A) The averaging period to be used for determining the average VO 
concentration for the hazardous waste stream on a mass-weighted average 
basis shall be designated and recorded. The averaging period can 
represent any time interval that the owner or operator determines is 
appropriate for the hazardous waste stream but shall not exceed 1 year.
    (B) A sufficient number of samples, but no less than four samples, 
shall be collected for the hazardous waste stream to represent the 
complete range of compositions and quantities that occur during the 
entire averaging period due to normal variations in the operating 
conditions for the source or process generating the hazardous waste 
stream. Examples of such normal variations are seasonal variations in 
waste quantity or fluctuations in ambient temperature.
    (C) All samples shall be collected and handled in accordance with 
written procedures prepared by the owner or operator and documented in a 
site sampling plan. This plan shall describe the procedure by which 
representative samples of the hazardous waste stream

[[Page 500]]

are collected such that a minimum loss of organics occurs throughout the 
sample collection and handling process, and by which sample integrity is 
maintained. A copy of the written sampling plan shall be maintained on-
site in the facility operating records. An example of an acceptable 
sampling plan includes a plan incorporating sample collection and 
handling procedures in accordance with the requirements specified in 
``Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,'' 
EPA Publication SW-846, (incorporated by reference--refer to 
Sec. 260.11(a) of this chapter), or in Method 25D in 40 CFR part 60, 
appendix A.
    (iii) Analysis. Each collected sample shall be prepared and analyzed 
in accordance with one or more of the methods listed in paragraphs 
(a)(3)(iii)(A) through (a)(3)(iii)(I) of this section, including 
appropriate quality assurance and quality control (QA/QC) checks and use 
of target compounds for calibration. If Method 25D in 40 CFR part 60, 
appendix A is not used, then one or more methods should be chosen that 
are appropriate to ensure that the waste determination accounts for and 
reflects all organic compounds in the waste with Henry's law constant 
values at least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-
liquid-phase (0.1 Y/X) [which can also be expressed as 1.8  x  
10-6 atmospheres/gram-mole/m\3\] at 25 degrees Celsius. Each 
of the analytical methods listed in paragraphs (a)(3)(iii)(B) through 
(a)(3)(iii)(G) of this section has an associated list of approved 
chemical compounds, for which EPA considers the method appropriate for 
measurement. If an owner or operator uses EPA Method 624, 625, 1624, or 
1625 in 40 CFR part 136, appendix A to analyze one or more compounds 
that are not on that method's published list, the Alternative Test 
Procedure contained in 40 CFR 136.4 and 136.5 must be followed. If an 
owner or operator uses EPA Method 8260(B) or 8270(C) in ``Test Methods 
for Evaluating Solid Waste, Physical/ Chemical Methods'', EPA 
Publication SW-846, (incorporated by reference--refer to Sec. 260.11(a) 
of this chapter) to analyze one or more compounds that are not on that 
method's published list, the procedures in paragraph (a)(3)(iii)(H) of 
this section must be followed. At the owner's or operator's discretion, 
the concentration of each individual chemical constituent measured in 
the waste by a method other than Method 25D may be corrected to the 
concentration had it been measured using Method 25D by multiplying the 
measured concentration by the constituent-specific adjustment factor 
(fm25D) as specified in paragraph (a)(4)(iii) of this 
section. Constituent-specific adjustment factors (fm25D) can 
be obtained by contacting the Waste and Chemical Processes Group, Office 
of Air Quality Planning and Standards, Research Triangle Park, NC 27711.
    (A) Method 25D in 40 CFR part 60, appendix A.
    (B) Method 624 in 40 CFR part 136, appendix A.
    (C) Method 625 in 40 CFR part 136, appendix A. Perform corrections 
to the compounds for which the analysis is being conducted based on the 
``accuracy as recovery'' using the factors in Table 7 of the method.
    (D) Method 1624 in 40 CFR part 136, appendix A.
    (E) Method 1625 in 40 CFR part 136, appendix A.
    (F) Method 8260(B) in ``Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods'', EPA Publication SW-846, (incorporated by 
reference--refer to Sec. 260.11(a) of this chapter). Maintain a formal 
quality assurance program consistent with the requirements of Method 
8260(B). The quality assurance program shall include the following 
elements:
    (1) Documentation of site-specific procedures to minimize the loss 
of compounds due to volatilization, biodegradation, reaction, or 
sorption during the sample collection, storage, preparation, 
introduction, and analysis steps.
    (2) Measurement of the overall accuracy and precision of the 
specific procedures.
    (G) Method 8270(C) in ``Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods'', EPA Publication SW-846, (incorporated by 
reference--refer to Sec. 260.11(a) of this chapter). Maintain a formal 
quality assurance program consistent with the requirements of Method 
8270(C). The quality

[[Page 501]]

assurance program shall include the following elements:
    (1) Documentation of site-specific procedures to minimize the loss 
of compounds due to volatilization, biodegradation, reaction, or 
sorption during the sample collection, storage, and preparation steps.
    (2) Measurement of the overall accuracy and precision of the 
specific procedures.
    (H) Any other EPA standard method that has been validated in 
accordance with ``Alternative Validation Procedure for EPA Waste and 
Wastewater Methods'', 40 CFR part 63, appendix D. As an alternative, 
other EPA standard methods may be validated by the procedure specified 
in paragraph (a)(3)(iii)(I) of this section.
    (I) Any other analysis method that has been validated in accordance 
with the procedures specified in Section 5.1 or Section 5.3, and the 
corresponding calculations in Section 6.1 or Section 6.3, of Method 301 
in 40 CFR part 63, appendix A. The data are acceptable if they meet the 
criteria specified in Section 6.1.5 or Section 6.3.3 of Method 301. If 
correction is required under section 6.3.3 of Method 301, the data are 
acceptable if the correction factor is within the range 0.7 to 1.30. 
Other sections of Method 301 are not required.
    (iv) Calculations. The average VO concentration (C) on a mass-
weighted basis shall be calculated by using the results for all samples 
analyzed in accordance with paragraph (a)(3)(iii) of this section and 
the following equation:
[GRAPHIC] [TIFF OMITTED] TR25NO96.000

Where:

C = Average VO concentration of the hazardous waste at the point of 
waste origination on a mass-weighted basis, ppmw.
i = Individual sample ``i'' of the hazardous waste.
n = Total number of samples of the hazardous waste collected (at least 
4) for the averaging period (not to exceed 1 year).
Qi = Mass quantity of hazardous waste stream represented by 
Ci, kg/hr.
QT = Total mass quantity of hazardous waste during the 
averaging period, kg/hr.
Ci = Measured VO concentration of sample ``i'' as determined 
in accordance with the requirements of Sec. 265.1084(a)(3)(iii) of this 
subpart, ppmw.

    (4) Use of owner or operator knowledge to determine average VO 
concentration of a hazardous waste at the point of waste origination.
    (i) Documentation shall be prepared that presents the information 
used as the basis for the owner's or operator's knowledge of the 
hazardous waste stream's average VO concentration. Examples of 
information that may be used as the basis for knowledge include: 
Material balances for the source or process generating the hazardous 
waste stream; constituent-specific chemical test data for the hazardous 
waste stream from previous testing that are still applicable to the 
current waste stream; previous test data for other locations managing 
the same type of waste stream; or other knowledge based on information 
included in manifests, shipping papers, or waste certification notices.
    (ii) If test data are used as the basis for knowledge, then the 
owner or operator shall document the test method, sampling protocol, and 
the means by which sampling variability and analytical variability are 
accounted for in the determination of the average VO concentration. For 
example, an owner or operator may use organic concentration test data 
for the hazardous waste stream that are validated in accordance with 
Method 301 in 40 CFR part 63, appendix A as the basis for knowledge of 
the waste.
    (iii) An owner or operator using chemical constituent-specific 
concentration test data as the basis for knowledge of the hazardous 
waste may adjust the test data to the corresponding average VO 
concentration value which would have been obtained had the waste samples 
been analyzed using Method 25D in 40 CFR part 60, appendix A. To adjust 
these data, the measured concentration for each individual chemical 
constituent contained in the waste is multiplied by the appropriate

[[Page 502]]

constituent-specific adjustment factor (fm25D).
    (iv) In the event that the Regional Administrator and the owner or 
operator disagree on a determination of the average VO concentration for 
a hazardous waste stream using knowledge, then the results from a 
determination of average VO concentration using direct measurement as 
specified in paragraph (a)(3) of this section shall be used to establish 
compliance with the applicable requirements of this subpart. The 
Regional Administrator may perform or request that the owner or operator 
perform this determination using direct measurement.
    (b) Waste determination procedures for treated hazardous waste.
    (1) An owner or operator shall perform the applicable waste 
determination for each treated hazardous waste placed in a waste 
management unit exempted under the provisions of Sec. 265.1083(c)(2) of 
this subpart from using air emission controls in accordance with 
standards specified in Sec. 265.1085 through Sec. 265.1088 of this 
subpart, as applicable to the waste management unit.
    (2) The owner or operator shall designate and record the specific 
provision in Sec. 265.1083(c)(2) of this subpart under which the waste 
determination is being performed. The waste determination for the 
treated hazardous waste shall be performed using the applicable 
procedures specified in paragraphs (b)(3) through (b)(9) of this 
section.
    (3) Procedure to determine the average VO concentration of a 
hazardous waste at the point of waste treatment.
    (i) Identification. The owner or operator shall identify and record 
the point of waste treatment for the hazardous waste.
    (ii) Sampling. Samples of the hazardous waste stream shall be 
collected at the point of waste treatment in a manner such that 
volatilization of organics contained in the waste and in the subsequent 
sample is minimized and an adequately representative sample is collected 
and maintained for analysis by the selected method.
    (A) The averaging period to be used for determining the average VO 
concentration for the hazardous waste stream on a mass-weighted average 
basis shall be designated and recorded. The averaging period can 
represent any time interval that the owner or operator determines is 
appropriate for the hazardous waste stream but shall not exceed 1 year.
    (B) A sufficient number of samples, but no less than four samples, 
shall be collected for the hazardous waste stream to represent the 
complete range of compositions and quantities that occur during the 
entire averaging period due to normal variations in the operating 
conditions for the process treating the hazardous waste stream. Examples 
of such normal variations are seasonal variations in waste quantity or 
fluctuations in ambient temperature.
    (C) All samples shall be collected and handled in accordance with 
written procedures prepared by the owner or operator and documented in a 
site sampling plan. This plan shall describe the procedure by which 
representative samples of the hazardous waste stream are collected such 
that a minimum loss of organics occurs throughout the sample collection 
and handling process, and by which sample integrity is maintained. A 
copy of the written sampling plan shall be maintained on-site in the 
facility operating records. An example of an acceptable sampling plan 
includes a plan incorporating sample collection and handling procedures 
in accordance with the requirements specified in ``Test Methods for 
Evaluating Solid Waste, Physical/Chemical Methods,'' EPA Publication No. 
SW-846 (incorporated by reference--refer to Sec. 260.11(a) of this 
chapter), or in Method 25D in 40 CFR part 60, appendix A.
    (iii) Analysis. Each collected sample shall be prepared and analyzed 
in accordance with one or more of the methods listed in paragraphs 
(b)(3)(iii)(A) through (b)(3)(iii)(I) of this section, including 
appropriate quality assurance and quality control (QA/QC) checks and use 
of target compounds for calibration. If Method 25D in 40 CFR part 60, 
appendix A is not used, then one or more methods should be chosen that 
are appropriate to ensure that the waste determination accounts for and 
reflects all organic compounds in the waste with Henry's law constant 
values at least 0.1 mole-fraction-in-the-gas-

[[Page 503]]

phase/mole-fraction-in-the-liquid-phase (0.1 Y/X) [which can also be 
expressed as 1.8 x 10-6 atmospheres/gram-mole/m3] 
at 25 degrees Celsius. Each of the analytical methods listed in 
paragraphs (b)(3)(iii)(B) through (b)(3)(iii)(G) of this section has an 
associated list of approved chemical compounds, for which EPA considers

are not on that method's published list, the procedures in paragraph 
(b)(3)(iii)(H) of this section must be followed. At the owner's or 
operator's discretion, the concentration of each individual chemical 
constituent measured in the waste by a method other than Method 25D may 
be corrected to the concentration had it been measured using Method 25D 
by multiplying the measured concentration by the constituent-specific 
adjustment factor (fm25D) as specified in paragraph 
(a)(4)(iii) of this section. Constituent-specific adjustment factors 
(fm25D) can be obtained by contacting the Waste and Chemical 
Processes Group, Office of Air Quality Planning and Standards, Research

requirements specified in ``Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods,'' EPA Publication No. SW-846, (incorporated 
by reference--refer to Sec. 260.11(a) of this chapter), or in Method 25D 
in 40 CFR part 60, appendix A.
    (ii) Analysis. Any appropriate one of the following methods may be 
used to analyze the samples and compute the maximum organic vapor 
pressure of the hazardous waste:
    (A) Method 25E in 40 CFR part 60 appendix A;
    (B) Methods described in American Petroleum Institute Publication 
2517, Third Edition, February 1989, ``Evaporative Loss from External 
Floating-Roof Tanks,'' (incorporated by reference--refer to Sec. 260.11 
of this chapter);
    (C) Methods obtained from standard reference texts;
    (D) ASTM Method 2879-92 (incorporated by reference--refer to 
Sec. 260.11 of this chapter); and
    (E) Any other method approved by the Regional Administrator.
    (4) Use of knowledge to determine the maximum organic vapor pressure 
of the hazardous waste. Documentation shall be prepared and recorded 
that presents the information used as the basis for the owner's or 
operator's knowledge that the maximum organic vapor pressure of the 
hazardous waste is less than the maximum vapor pressure limit listed in 
Sec. 265.1085(b)(1)(i) of this subpart for the applicable tank design 
capacity category. An example of information that may be used is 
documentation that the hazardous waste is generated by a process for 
which at other locations it previously has been determined by direct 
measurement that the waste maximum organic vapor pressure is less than 
the maximum vapor pressure limit for the appropriate tank design 
capacity category.
    (d) Procedure for determining no detectable organic emissions for 
the purpose of complying with this subpart:
    (1) The test shall be conducted in accordance with the procedures 
specified in Method 21 of 40 CFR part 60, appendix A. Each potential 
leak interface (i.e., a location where organic vapor leakage could 
occur) on the cover and associated closure devices shall be checked. 
Potential leak interfaces that are associated with covers and closure 
devices include, but are not limited to: The interface of the cover and 
its foundation mounting; the periphery of any opening on the cover and 
its associated closure device; and the sealing seat interface on a 
spring-loaded pressure relief valve.

[[Page 508]]

    (2) The test shall be performed when the unit contains a hazardous 
waste having an organic concentration representative of the range of 
concentrations for the hazardous waste expected to be managed in the 
unit. During the test, the cover and closure devices shall be secured in 
the closed position.
    (3) The detection instrument shall meet the performance criteria of 
Method 21 of 40 CFR part 60, appendix A, except the instrument response 
factor criteria in section 3.1.2(a) of Method 21 shall be for the 
average composition of the organic constituents in the hazardous waste 
placed in the waste management unit, not for each individual organic 
constituent.
    (4) The detection instrument shall be calibrated before use on each 
day of its use by the procedures specified in Method 21 of 40 CFR part 
60, appendix A.
    (5) Calibration gases shall be as follows:
    (i) Zero air (less than 10 ppmv hydrocarbon in air), and
    (ii) A mixture of methane in air at a concentration of 
approximately, but less than 10,000 ppmv.
    (6) The background level shall be determined according to the 
procedures in Method 21 of 40 CFR part 60, appendix A.
    (7) Each potential leak interface shall be checked by traversing the 
instrument probe around the potential leak interface as close to the 
interface as possible, as described in Method 21 of 40 CFR part 60, 
appendix A. In the case when the configuration of the cover or closure 
device prevents a complete traverse of the interface, all accessible 
portions of the interface shall be sampled. In the case when the 
configuration of the closure device prevents any sampling at the 
interface and the device is equipped with an enclosed extension or horn 
(e.g., some pressure relief devices), the instrument probe inlet shall 
be placed at approximately the center of the exhaust area to the 
atmosphere.
    (8) The arithmetic difference between the maximum organic 
concentration indicated by the instrument and the background level shall 
be compared with the value of 500 ppmv except when monitoring a seal 
around a rotating shaft that passes through a cover opening, in which 
case the comparison shall be as specified in paragraph (d)(9) of this 
section. If the difference is less than 500 ppmv, then the potential 
leak interface is determined to operate with no detectable organic 
emissions.
    (9) For the seals around a rotating shaft that passes through a 
cover opening, the arithmetic difference between the maximum organic 
concentration indicated by the instrument and the background level shall 
be compared with the value of 10,000 ppmw. If the difference is less 
than 10,000 ppmw, then the potential leak interface is determined to 
operate with no detectable organic emissions.

operator to a temperature that is greater than the temperature at which 
the maximum organic vapor pressure of the hazardous waste is determined 
for the purpose of complying with paragraph (b)(1)(i) of this section.
    (iii) The hazardous waste in the tank is not treated by the owner or 
operator using a waste stabilization process, as defined in 
Sec. 265.1081 of this subpart.
    (2) For a tank that manages hazardous waste that does not meet all 
of the conditions specified in paragraphs (b)(1)(i) through (b)(1)(iii) 
of this section, the owner or operator shall control air pollutant 
emissions from the tank by using Tank Level 2 controls in accordance 
with the requirements of paragraph (d) of this section. Examples of 
tanks required to use Tank Level 2 controls include: A tank used for a 
waste stabilization process; and a tank for which the hazardous waste in 
the tank has a maximum organic vapor pressure that is equal to or 
greater than the maximum organic vapor pressure limit for the tank's

the tank. The maximum organic vapor pressure shall be determined using 
the procedures specified in Sec. 265.1084(c) of this subpart. 
Thereafter, the owner or operator shall perform a new determination 
whenever changes to the hazardous waste managed in the tank could 
potentially cause the maximum organic vapor pressure to increase to a 
level that is equal to or greater than the maximum organic vapor 
pressure limit for the tank design capacity category specified in 
paragraph (b)(1)(i) of this section, as applicable to the tank.
    (2) The tank shall be equipped with a fixed roof designed to meet 
the following specifications:
    (i) The fixed roof and its closure devices shall be designed to form 
a continuous barrier over the entire surface area of the hazardous waste 
in the tank. The fixed roof may be a separate cover installed on the 
tank (e.g., a removable cover mounted on an open-top tank) or may be an 
integral part of the tank structural design (e.g., a horizontal 
cylindrical tank equipped with a hatch).
    (ii) The fixed roof shall be installed in a manner such that there 
are no visible cracks, holes, gaps, or other open spaces between roof 
section joints or between the interface of the roof edge and the tank

of the fixed roof and closure devices throughout their intended service 
life. Factors to be considered when selecting the materials for and 
designing the fixed roof and closure devices shall include: Organic 
vapor permeability, the effects of any contact with the hazardous waste 
or its vapors managed in the tank; the effects of outdoor exposure to 
wind, moisture, and sunlight; and the operating practices used for the 
tank on which the fixed roof is installed.
    (3) Whenever a hazardous waste is in the tank, the fixed roof shall 
be installed with each closure device secured in the closed position 
except as follows:

[[Page 510]]

    (i) Opening of closure devices or removal of the fixed roof is 
allowed at the following times:
    (A) To provide access to the tank for performing routine inspection, 
maintenance, or other activities needed for normal operations. Examples 
of such activities include those times when a worker needs to open a 
port to sample the liquid in the tank, or when a worker needs to open a 
hatch to maintain or repair equipment. Following completion of the 
activity, the owner or operator shall promptly secure the closure device 
in the closed position or reinstall the cover, as applicable, to the 
tank.
    (B) To remove accumulated sludge or other residues from the bottom

conservation vent, or similar type of pressure relief device which vents 
to the atmosphere is allowed during normal operations for the purpose of 
maintaining the tank internal pressure in accordance with the tank 
design specifications. The device shall be designed to operate with no 
detectable organic emissions when the device is secured in the closed 
position. The settings at which the device opens shall be established 
such that the device remains in the closed position whenever the tank 
internal pressure is within the internal pressure operating range 
determined by the owner or operator based on the tank manufacturer 
recommendations, applicable regulations, fire protection and prevention 
codes, standard engineering codes and practices, or other requirements 
for the safe handling of flammable, ignitable, explosive, reactive, or 
hazardous materials. Examples of normal operating conditions that may 
require these devices to open are during those times when the tank 
internal pressure exceeds the internal pressure operating range for the 
tank as a result of loading operations or diurnal ambient temperature 
fluctuations.
    (iii) Opening of a safety device, as defined in Sec. 265.1081 of 
this subpart, is allowed at any time conditions require doing so to 
avoid an unsafe condition.
    (4) The owner or operator shall inspect the air emission control 
equipment in accordance with the following requirements.

gaskets on closure devices; and broken or missing hatches, access 
covers, caps, or other closure devices.
    (ii) The owner or operator shall perform an initial inspection of 
the fixed roof and its closure devices on or before the date that the 
tank becomes subject to this section. Thereafter, the owner or operator 
shall perform the inspections at least once every year except under the

maintaining the container internal pressure in accordance with the 
design specifications of the container. The device shall be designed to 
operate with no detectable organic emissions when the device is secured 
in the closed position. The settings at which the device opens shall be 
established such that the device remains in the closed position whenever 
the internal pressure of the container is within the internal pressure 
operating range determined by the owner or operator based on container 
manufacturer recommendations, applicable regulations, fire protection 
and prevention codes, standard engineering codes and practices, or other 
requirements for the safe handling of flammable, ignitable, explosive, 
reactive, or hazardous materials. Examples of normal operating 
conditions that may require these devices to open are during those times 
when the internal pressure of the container exceeds the internal 
pressure operating range for the container as a result of loading 
operations or diurnal ambient temperature fluctuations.
    (v) Opening of a safety device, as defined in Sec. 265.1081 of this 
subpart, is allowed at any time conditions require doing so to avoid an

    The requirements of this subpart apply to owners or operators who 
store or treat hazardous waste in units designed and operated under 
Sec. 265.1101 of this subpart. These provisions will become effective on 
February 18, 1993, although the owner or operator may notify the 
Regional Administrator of his intent to be bound by this subpart at an 
earlier time. The owner or operator is not subject to the definition of 
land disposal in RCRA section 3004(k) provided that the unit:
    (a) Is a completely enclosed, self-supporting structure that is 
designed and constructed of manmade materials of sufficient strength and 
thickness to support themselves, the waste contents, and any personnel 
and heavy equipment that operate within the units, and to prevent 
failure due to pressure gradients, settlement, compression, or uplift, 
physical contact with the hazardous wastes to which they are exposed; 
climatic conditions; and the stresses of daily operation, including the 
movement of heavy equipment within the unit and contact of such 
equipment with containment walls;
    (b) Has a primary barrier that is designed to be sufficiently 
durable to withstand the movement of personnel and handling equipment 
within the unit;
    (c) If the unit is used to manage liquids, has:
    (1) A primary barrier designed and constructed of materials to 
prevent migration of hazardous constituents into the barrier;
    (2) A liquid collection system designed and constructed of materials 
to minimize the accumulation of liquid on the primary barrier; and

[[Page 533]]

    (3) A secondary containment system designed and constructed of 
materials to prevent migration of hazardous constituents into the 
barrier, with a leak detection and liquid collection system capable of 
detecting, collecting, and removing leaks of hazardous constituents at 
the earliest possible time, unless the unit has been granted a variance 
from the secondary containment system requirements under 
Sec. 265.1101(b)(4);
    (d) Has controls as needed to permit fugitive dust emissions; and
    (e) Is designed and operated to ensure containment and prevent the 
tracking of materials from the unit by personnel or equipment.



Sec. 265.1101  Design and operating standards.

    (a) All containment buildings must comply with the following design 
standards:
    (1) The containment building must be completely enclosed with a 
floor, walls, and a roof to prevent exposure to the elements, (e.g., 
precipitation, wind, run-on), and to assure containment of managed 
wastes.
    (2) The floor and containment walls of the unit, including the 
secondary containment system if required under paragraph (b) of this 
section, must be designed and constructed of materials of sufficient 
strength and thickness to support themselves, the waste contents, and 
any personnel and heavy equipment that operate within the unit, and to 
prevent failure due to pressure gradients, settlement, compression, or 
uplift, physical contact with the hazardous wastes to which they are 
exposed; climatic conditions; and the stresses of daily operation, 
including the movement of heavy equipment within the unit and contact of 
such equipment with containment walls. The unit must be designed so that 
it has sufficient structural strength to prevent collapse or other 
failure. All surfaces to be in contact with hazardous wastes must be 
chemically compatible with those wastes. EPA will consider standards 
established by professional organizations generally recognized by the 
industry such as the American Concrete Institute (ACI) and the American 
Society of Testing Materials (ASTM) in judging the structural integrity 
requirements of this paragraph. If appropriate to the nature of the 
waste management operation to take place in the unit, an exception to 
the structural strength requirement may be made for light-weight doors 
and windows that meet these criteria:
    (i) They provide an effective barrier against fugitive dust 
emissions under paragraph (c)(1)(iv); and
    (ii) The unit is designed and operated in a fashion that assures 
that wastes will not actually come in contact with these openings.
    (3) Incompatible hazardous wastes or treatment reagents must not be 
placed in the unit or its secondary containment system if they could 
cause the unit or secondary containment system to leak, corrode, or 
otherwise fail.
    (4) A containment building must have a primary barrier designed to 
withstand the movement of personnel, waste, and handling equipment in 
the unit during the operating life of the unit and appropriate for the 
physical and chemical characteristics of the waste to be managed.
    (b) For a containment building used to manage hazardous wastes 
containing free liquids or treated with free liquids (the presence of 
which is determined by the paint filter test, a visual examination, or 
other appropriate means), the owner or operator must include:
    (1) A primary barrier designed and constructed of materials to 
prevent the migration of hazardous constituents into the barrier (e.g. a 
geomembrane covered by a concrete wear surface).
    (2) A liquid collection and removal system to prevent the 
accumulation of liquid on the primary barrier of the containment 
building:
    (i) The primary barrier must be sloped to drain liquids to the 
associated collection system; and
    (ii) Liquids and waste must be collected and removed to minimize 
hydraulic head on the containment system at the earliest practicable 
time that protects human health and the environment.
    (3) A secondary containment system including a secondary barrier 
designed and constructed to prevent migration of hazardous constituents 
into the barrier, and a leak detection system that

[[Page 534]]

is capable of detecting failure of the primary barrier and collecting 
accumulated hazardous wastes and liquids at the earliest practicable 
time.
    (i) The requirements of the leak detection component of the 
secondary containment system are satisfied by installation of a system 
that is, at a minimum:
    (A) Constructed with a bottom slope of 1 percent or more; and
    (B) Constructed of a granular drainage material with a hydraulic 
conductivity of 1  x  10-\2\ cm/sec or more and a thickness 
of 12 inches (30.5 cm) or more, or constructed of synthetic or geonet 
drainage materials with a trasmissivity of 3  x  10-\5\ m 
\2\/sec or more.
    (ii) If treatment is to be conducted in the building, an area in 
which such treatment will be conducted must be designed to prevent the 
release of liquids, wet materials, or liquid aerosols to other portions 
of the building.
    (iii) The secondary containment system must be constructed of 
materials that are chemically resistant to the waste and liquids managed 
in the containment building and of sufficient strength and thickness to 
prevent collapse under the pressure exerted by overlaying materials and 
by any equipment used in the containment building. (Containment 
buildings can serve as secondary containment systems for tanks placed 
within the building under certain conditions. A containment building can 
serve as an external liner system for a tank, provided it meets the 
requirements of Sec. 265.193(d)(1). In addition, the containment 
building must meet the requirements of Sec. 265.193 (b) and (c) to be 
considered an acceptable secondary containment system for a tank.)
    (4) For existing units other than 90-day generator units, the 
Regional Administrator may delay the secondary containment requirement 
for up to two years, based on a demonstration by the owner or operator 
that the unit substantially meets the standards of this Subpart. In 
making this demonstration, the owner or operator must:
    (i) Provide written notice to the Regional Administrator of their 
request by February 18, 1993. This notification must describe the unit 
and its operating practices with specific reference to the performance 
of existing containment systems, and specific plans for retrofitting the 
unit with secondary containment;
    (ii) Respond to any comments from the Regional Administrator on 
these plans within 30 days; and
    (iii) Fulfill the terms of the revised plans, if such plans are 
approved by the Regional Administrator.
    (c) Owners or operators of all containment buildings must:
    (1) Use controls and practices to ensure containment of the 
hazardous waste within the unit; and, at a minimum:
    (i) Maintain the primary barrier to be free of significant cracks, 
gaps, corrosion, or other deterioration that could cause hazardous waste 
to be released from the primary barrier;
    (ii) Maintain the level of the stored/treated hazardous waste within 
the containment walls of the unit so that the height of any containment 
wall is not exceeded;
    (iii) Take measures to prevent the tracking of hazardous waste out 
of the unit by personnel or by equipment used in handling the waste. An 
area must be designated to decontaminate equipment and any rinsate must 
be collected and properly managed; and
    (iv) Take measures to control fugitive dust emissions such that any 
openings (doors, windows, vents, cracks, etc.) exhibit no visible 
emissions. In addition, all associated particulate collection devices 
(e.g., fabric filter, electrostatic precipitator) must be operated and 
maintained with sound air pollution control practices. This state of no 
visible emissions must be maintained effectively at all times during 
normal operating conditions, including when vehicles and personnel are 
entering and exiting the unit.
    (2) Obtain certification by a qualified registered professional 
engineer that the containment building design meets the requirements of 
paragraphs (a) through (c) of this section. For units placed into 
operation prior to February 18, 1993, this certification must be placed 
in the facility's operating record (on-site files for generators who are 
not formally required to have operating records) no later than 60 days

[[Page 535]]

after the date of initial operation of the unit. After February 18, 
1993, PE certification will be required prior to operation of the unit.
    (3) Throughout the active life of the containment building, if the 
owner or operator detects a condition that could lead to or has caused a 
release of hazardous waste, must repair the condition promptly, in 
accordance with the following procedures.
    (i) Upon detection of a condition that has led to a release of 
hazardous waste (e.g., upon detection of leakage from the primary 
barrier) the owner or operator must:
    (A) Enter a record of the discovery in the facility operating 
record;
    (B) Immediately remove the portion of the containment building 
affected by the condition from service;
    (C) Determine what steps must be taken to repair the containment 
building, remove any leakage from the secondary collection system, and 
establish a schedule for accomplishing the cleanup and repairs; and
    (D) Within 7 days after the discovery of the condition, notify the 
Regional Administrator of the condition, and within 14 working days, 
provide a written notice to the Regional Administrator with a 
description of the steps taken to repair the containment building, and 
the schedule for accomplishing the work.
    (ii) The Regional Administrator will review the information 
submitted, make a determination regarding whether the containment 
building must be removed from service completely or partially until 
repairs and cleanup are complete, and notify the owner or operator of 
the determination and the underlying rationale in writing.
    (iii) Upon completing all repairs and cleanup the owner or operator 
must notify the Regional Administrator in writing and provide a 
verification, signed by a qualified, registered professional engineer, 
that the repairs and cleanup have been completed according to the 
written plan submitted in accordance with paragraph (c)(3)(i)(D) of this 
section.
    (4) Inspect and record in the facility's operating record, at least 
once every seven days, data gathered from monitoring equipment and leak 
detection equipment as well as the containment building and the area 
immediately surrounding the containment building to detect signs of 
releases of hazardous waste.
    (d) For containment building that contains both areas with and 
without secondary containment, the owner or operator must:
    (1) Design and operate each area in accordance with the requirements 
enumerated in paragraphs (a) through (c) of this section;
    (2) Take measures to prevent the release of liquids or wet materials 
into areas without secondary containment; and
    (3) Maintain in the facility's operating log a written description 
of the operating procedures used to maintain the integrity of areas 
without secondary containment.
    (e) Notwithstanding any other provision of this subpart, the 
Regional Administrator may waive requirements for secondary containment 
for a permitted containment building where the owner or operator 
demonstrates that the only free liquids in the unit are limited amounts 
of dust suppression liquids required to meet occupational health and 
safety requirements, and where containment of managed wastes and liquids 
can be assured without a secondary containment system.



Sec. 265.1102  Closure and post-closure care.

    (a) At closure of a containment building, the owner or operator must 
remove or decontaminate all waste residues, contaminated containment 
system components (liners, etc.), contaminated subsoils, and structures 
and equipment contaminated with waste and leachate, and manage them as 
hazardous waste unless Sec. 261.3(d) of this chapter applies. The 
closure plan, closure activities, cost estimates for closure, and 
financial responsibility for containment buildings must meet all of the 
requirements specified in subparts G and H of this part.
    (b) If, after removing or decontaminating all residues and making 
all reasonable efforts to effect removal or decontamination of 
contaminated components, subsoils, structures, and

[[Page 536]]

equipment as required in paragraph (a) of this section, the owner or 
operator finds that not all contaminated subsoils can be practicably 
removed or decontaminated, he must close the facility and perform post-
closure care in accordance with the closure and post-closure 
requirements that apply to landfills (Sec. 265.310). In addition, for 
the purposes of closure, post-closure, and financial responsibility, 
such a containment building is then considered to be a landfill, and the 
owner or operator must meet all of the requirements for landfills 
specified in subparts G and H of this part.

    Source: 62 FR 6653, Feb. 12, 1997, unless otherwise noted.

    Effective Date Note: At 62 FR 6653, Feb. 12, 1997, subpart EE was 
added, effective Aug. 12, 1997.



Sec. 265.1200  Applicability.

    The requirements of this subpart apply to owners or operators who 
store munitions and explosive hazardous wastes, except as Sec. 265.1 
provides otherwise. (NOTE: Depending on explosive hazards, hazardous 
waste munitions and explosives may also be managed in other types of 
storage units, including containment buildings (40 CFR part 265, subpart 
DD), tanks (40 CFR part 265, subpart J), or containers (40 CFR part 265, 
subpart I); See 40 CFR 266.205 for storage of waste military munitions).



Sec. 265.1201  Design and operating standards.

    (a) Hazardous waste munitions and explosives storage units must be 
designed and operated with containment systems, controls, and 
monitoring, that:
    (1) Minimize the potential for detonation or other means of release 
of hazardous waste, hazardous constituents, hazardous decomposition 
products, or contaminated run-off, to the soil, ground water, surface 
water, and atmosphere;
    (2) Provide a primary barrier, which may be a container (including a 
shell) or tank, designed to contain the hazardous waste;
    (3) For wastes stored outdoors, provide that the waste and 
containers will not be in standing precipitation;
    (4) For liquid wastes, provide a secondary containment system that 
assures that any released liquids are contained and promptly detected 
and removed from the waste area, or vapor detection system that assures 
that any released liquids or vapors are promptly detected and an 
appropriate response taken (e.g., additional containment, such as 
overpacking, or removal from the waste area); and
    (5) Provide monitoring and inspection procedures that assure the 
controls and containment systems are working as designed and that 
releases that may adversely impact human health or the environment are 
not escaping from the unit.
    (b) Hazardous waste munitions and explosives stored under this 
subpart may be stored in one of the following:
    (1) Earth-covered magazines. Earth-covered magazines must be:
    (i) Constructed of waterproofed, reinforced concrete or structural 
steel arches, with steel doors that are kept closed when not being 
accessed;
    (ii) Designed and constructed:
    (A) To be of sufficient strength and thickness to support the weight 
of any explosives or munitions stored and any equipment used in the 
unit;
    (B) To provide working space for personnel and equipment in the 
unit; and
    (C) To withstand movement activities that occur in the unit; and
    (iii) Located and designed, with walls and earthen covers that 
direct an explosion in the unit in a safe direction, so as to minimize 
the propagation of an explosion to adjacent units and to minimize other 
effects of any explosion.
    (2) Above-ground magazines. Above-ground magazines must be located 
and designed so as to minimize the propagation of an explosion to 
adjacent units and to minimize other effects of any explosion.
    (3) Outdoor or open storage areas. Outdoor or open storage areas 
must be located and designed so as to minimize

[[Page 537]]

the propagation of an explosion to adjacent units and to minimize other 
effects of any explosion.
    (c) Hazardous waste munitions and explosives must be stored in 
accordance with a Standard Operating Procedure specifying procedures to 
ensure safety, security, and environmental protection. If these 
procedures serve the same purpose as the security and inspection 
requirements of 40 CFR 265.14, the preparedness and prevention 
procedures of 40 CFR part 265, subpart C, and the contingency plan and 
emergency procedures requirements of 40 CFR part 265, subpart D, then 
these procedures will be used to fulfill those requirements.
    (d) Hazardous waste munitions and explosives must be packaged to 
ensure safety in handling and storage.
    (e) Hazardous waste munitions and explosives must be inventoried at 
least annually.
    (f) Hazardous waste munitions and explosives and their storage units 
must be inspected and monitored as necessary to ensure explosives safety 
and to ensure that there is no migration of contaminants out of the 
unit.



Sec. 265.1202  Closure and post-closure care.

    (a) At closure of a magazine or unit which stored hazardous waste 
under this subpart, the owner or operator must remove or decontaminate 
all waste residues, contaminated containment system components, 
contaminated subsoils, and structures and equipment contaminated with 
waste, and manage them as hazardous waste unless Sec. 261.3(d) of this 
chapter applies. The closure plan, closure activities, cost estimates 
for closure, and financial responsibility for magazines or units must 
meet all of the requirements specified in subparts G and H of this part, 
except that the owner or operator may defer closure of the unit as long 
as it remains in service as a munitions or explosives magazine or 
storage unit.
    (b) If, after removing or decontaminating all residues and making 
all reasonable efforts to effect removal or decontamination of 
contaminated components, subsoils, structures, and equipment as required 
in paragraph (a) of this section, the owner or operator finds that not 
all contaminated subsoils can be practicably removed or decontaminated, 
he or she must close the facility and perform post-closure care in 
accordance with the closure and post-closure requirements that apply to 
landfills (40 CFR 264.310).

                         Appendices to Part 265

           Appendix I to Part 265--Recordkeeping Instructions

    The recordkeeping provisions of Sec. 265.73 specify that an owner or 
operator must keep a written operating record at his facility. This 
appendix provides additional instructions for keeping portions  of the 
operating record. See Sec. 265.73(b) for additional recordkeeping 
requirements.
    The following information must be recorded, as it becomes available, 
and maintained in the operating record until closure of the facility in 
the following manner:
    Records of each hazardous waste received, treated, stored, or 
disposed of at the facility which include the following:
    (1) A description by its common name and the EPA Hazardous Waste 
Number(s) from part 261 of this chapter which apply to the waste. The 
waste description also must include the waste's physical form, i.e., 
liquid, sludge, solid, or contained gas. If the waste is not listed in 
part 261, subpart D, of this chapter, the description also must include 
the process that produced it (for example, solid filter cake from 
production of ______, EPA Hazardous Waste Number W051).
    Each hazardous waste listed in part 261, subpart D, of this chapter, 
and each hazardous waste characteristic defined in part 261, subpart C, 
of this chapter, has a four-digit EPA Hazardous Waste Number assigned to 
it. This number must be used for recordkeeping and reporting purposes. 
Where a hazardous waste contains more than one listed hazardous waste, 
or where more than one hazardous waste characteristic applies to the 
waste, the waste description must include all applicable EPA Hazardous 
Waste Numbers.
    (2) The estimated or manifest-reported weight, or volume and 
density, where applicable, in one of the units of measure specified in 
Table 1; and

             Appendix IV to Part 265--Tests for Significance

    As required in Sec. 265.93(b) the owner or operator must use the 
Student's t-test to determine statistically significant changes in the 
concentration or value of an indicator parameter in periodic ground-
water samples when compared to the initial background concentration or 
value of that indicator parameter. The comparison must consider 
individually each of the wells in the monitoring system. For three of 
the indicator parameters (specific conductance, total organic carbon, 
and total organic halogen) a single-tailed Student's t-test must be used 
to test at the 0.01 level of significance for significant increases over 
background. The difference test for pH must be a two-tailed Student's t-
test at the overall 0.01 level of significance.
    The student's t-test involves calculation of the value of a t-
statistic for each comparison of the mean (average) concentration or 
value (based on a minimum of four replicate measurements) of an 
indicator parameter with its initial background concentration or value. 
The calculated value of the t-statistic must then be compared to the 
value of the t-statistic found in a table for t-test of significance at 
the specified level of significance. A calculated value of t which 
exceeds the value of t found in the table indicates a statistically 
significant change in the concentration or value of the indicator 
parameter.
    Formulae for calculation of the t-statistic and tables for t-test of 
significance can be found in most introductory statistics texts.

   Appendix V to Part 265--Examples of Potentially Incompatible Waste

    Many hazardous wastes, when mixed with other waste or materials at a 
hazardous waste facility, can produce effects which are harmful to human 
health and the environment, such as (1) heat or pressure, (2) fire or 
explosion, (3) violent reaction, (4) toxic dusts, mists, fumes, or 
gases, or (5) flammable fumes or gases.
    Below are examples of potentially incompatible wastes, waste 
components, and materials, along with the harmful consequences which 
result from mixing materials in one group with materials in another 
group. The list is intended as a guide to owners or operators of 
treatment, storage, and disposal facilities, and to enforcement and 
permit granting officials, to indicate the need for special precautions 
when managing these potentially incompatible waste materials or 
components.
    This list is not intended to be exhaustive. An owner or operator 
must, as the regulations require, adequately analyze his wastes so that 
he can avoid creating uncontrolled substances or reactions of the type 
listed below, whether they are listed below or not.
    It is possible for potentially incompatible wastes to be mixed in a 
way that precludes a reaction (e.g., adding acid to water rather than 
water to acid) or that neutralizes them (e.g., a strong acid mixed with 
a strong base), or that controls substances produced (e.g., by 
generating flammable gases in a

[[Page 540]]

closed tank equipped so that ignition cannot occur, and burning the 
gases in an incinerator).
    In the lists below, the mixing of a Group A material with a Group B 
material may have the potential consequence as noted.
