                               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, 2000), 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). 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.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

Sec. 61.02  Definitions.

    The terms used in this part are defined in the Act or in this 
section as follows:
    Act means the Clean Air Act (42 U.S.C. 7401 et seq.).
    Administrator means the Administrator of the Environmental 
Protection Agency or his authorized representative.
    Alternative method means any method of sampling and analyzing for an 
air pollutant which is not a reference method but which has been 
demonstrated to the Administrator's satisfaction to produce results 
adequate for the Administrator's determination of compliance.
    Approved permit program means a State permit program approved by the 
Administrator as meeting the requirements of part 70 of this chapter or 
a Federal permit program established in this chapter pursuant to title V 
of the Act (42 U.S.C. 7661).

operational change to a stationary source which exceeds the product of 
the applicable ``annual asset guideline repair allowance percentage'' 
specified in the latest edition of Internal Revenue Service (IRS) 
Publication 534 and the stationary source's basis, as defined by section 
1012 of the Internal Revenue Code. However, the total expenditure for a 
physical or operational change to a stationary source must not be 
reduced by any ``excluded additions'' as defined for stationary sources 
constructed after December 31, 1981, in IRS Publication 534, as would be 
done for tax purposes. In addition, ``annual asset guideline repair 
allowance'' may be used even though it is excluded for tax purposes in 
IRS Publication 534.
    Commenced means, with respect to the definition of ``new source'' in 
section 111(a)(2) of the Act, that an owner or operator has undertaken a 
continuous program of construction or modification or that an owner or 
operator has entered into a contractual obligation to undertake and 
complete, within a reasonable time, a continuous program of construction 
or modification.
    Compliance schedule means the date or dates by which a source or

affected facility.
    Effective date is the date of promulgation in the Federal Register 
of an applicable standard or other regulation under this part.
    Existing source means any stationary source which is not a new 
source.
    Issuance of a part 70 permit will occur, if the State is the 
permitting authority, in accordance with the requirements of part 70 of 
this chapter and the applicable, approved State permit program. When the 
EPA is the permitting authority, issuance of a title V permit occurs 
immediately after the EPA takes final action on the final permit.
    Monitoring system means any system, required under the monitoring 
sections in applicable subparts, used to sample and condition (if 
applicable), to analyze, and to provide a record of emissions or process 
parameters.
    New source means any stationary source, the construction or 
modification of which is commenced after the publication in the Federal 
Register of proposed national emission standards for hazardous air 
pollutants which will be applicable to such source.
    Owner or operator means any person who owns, leases, operates, 
controls, or supervises a stationary source.
    Part 70 permit means any permit issued, renewed, or revised pursuant 
to part 70 of this chapter.
    Permit program means a comprehensive State operating permit system 
established pursuant to title V of the Act (42 U.S.C. 7661) and 
regulations codified in part 70 of this chapter and applicable State 
regulations, or a comprehensive Federal operating permit system 
established pursuant to title V of the Act

[[Page 10]]

and regulations codified in this chapter.
    Permitting authority means:
    (1) The State air pollution control agency, local agency, other 
State agency, or other agency authorized by the Administrator to carry 
out a permit program under part 70 of this chapter; or
    (2) The Administrator, in the case of EPA-implemented permit 
programs under title V of the Act (42 U.S.C. 7661).
    Reference method means any method of sampling and analyzing for an 
air pollutant, as described in Appendix B to this part.
    Run means the net period of time during which an emission sample is 
collected. Unless otherwise specified, a run may be either intermittent 
or continuous within the limits of good engineering practice.
    Standard means a national emission standard including a design, 
equipment, work practice or operational standard for a hazardous air 
pollutant proposed or promulgated under this part.
    Startup means the setting in operation of a stationary source for 
any purpose.
    State means all non-Federal authorities, including local agencies, 
interstate associations, and State-wide programs, that have delegated 
authority to implement:
    (1) The provisions of this part; and/or
    (2) The permit program established under part 70 of this chapter. 
The term State shall have its conventional meaning where clear from the 
context.
    Stationary source means any building, structure, facility, or 
installation which emits or may emit any air pollutant which has been 
designated as hazardous by the Administrator.
    Title V permit means any permit issued, renewed, or revised pursuant 
to Federal or State regulations established to implement title V of the 
Act (42 U.S.C. 7661). A title V permit issued by a State permitting 
authority is called a part 70 permit in this part.

this section or Sec. 61.07(b) shall be provided to the Administrator 
within 30 days after the change. However, if any change will result from 
modification of the source, Secs. 61.07(c) and 61.08 apply.
    (d) A possible format for reporting under this section is included 
as appendix A of this part. Advice on reporting the status of compliance 
may be obtained from the Administrator.
    (e) For the purposes of this part, time periods specified in days 
shall be measured in calendar days, even if the word ``calendar'' is 
absent, unless otherwise specified in an applicable requirement.
    (f) For the purposes of this part, if an explicit postmark deadline 
is not specified in an applicable requirement for the submittal of a 
notification, application, report, or other written communication to the 
Administrator, the owner or operator shall postmark the submittal on or 
before the number of days specified in the applicable requirement. For 
example, if a notification must be submitted 15 days before a particular 
event is scheduled to take place, the notification shall be postmarked 
on or before 15 days preceding the event; likewise, if a notification 
must be submitted 15 days after a particular event takes place, the 
notification shall be postmarked on or before 15 days following the end 
of the event. The use of reliable non-Government mail carriers that 
provide indications of verifiable delivery of information required to be 
submitted to the Administrator, similar to the postmark provided by the 
U.S. Postal Service, or alternative means of delivery agreed to by the 
permitting authority, is acceptable.
    (g) Notwithstanding time periods or postmark deadlines specified in 
this part for the submittal of information to the Administrator by an 
owner or operator, or the review of such information by the 
Administrator, such time periods or deadlines may be changed by mutual 
agreement between the owner or operator and the Administrator. 
Procedures governing the implementation of this provision are specified 
in paragraph (j) of this section.
    (h) If an owner or operator of a stationary source in a State with 
delegated authority is required to submit reports under this part to the 
State, and if the State has an established timeline for the submission 
of reports that is consistent with the reporting frequency(ies) 
specified for such source under this part, the owner or operator may 
change the dates by which reports under this part shall be submitted 
(without changing the frequency of reporting) to be consistent with the 
State's schedule by mutual agreement between the owner or operator and 
the State. The allowance in the previous sentence applies in each State 
beginning 1 year after the source is required to be in compliance with 
the applicable subpart in this part. Procedures governing the 
implementation of this provision are specified in paragraph (j) of this 
section.
    (i) If an owner or operator supervises one or more stationary 
sources affected by standards set under this part and standards set 
under part 60, part 63, or both such parts of this chapter, he/she may 
arrange by mutual agreement between the owner or operator and the 
Administrator (or the State with an approved permit program) a common

[[Page 23]]

schedule on which reports required by each applicable standard shall be 
submitted throughout the year. The allowance in the previous sentence 
applies in each State beginning 1 year after the source is required to 
be in compliance with the applicable subpart in this part, or 1 year 
after the source is required to be in compliance with the applicable 
part 60 or part 63 standard, whichever is latest. Procedures governing 
the implementation of this provision are specified in paragraph (j) of 
this section.
    (j)(1)(i) Until an adjustment of a time period or postmark deadline 
has been approved by the Administrator under paragraphs (j)(2) and 
(j)(3) of this section, the owner or operator of an affected source 
remains strictly subject to the requirements of this part.
    (ii) An owner or operator shall request the adjustment provided for 
in paragraphs (j)(2) and (j)(3) of this section each time he or she 
wishes to change an applicable time period or postmark deadline 
specified in this part.
    (2) Notwithstanding time periods or postmark deadlines specified in 
this part for the submittal of information to the Administrator by an 
owner or operator, or the review of such information by the 
Administrator, such time periods or deadlines may be changed by mutual 
agreement between the owner or operator and the Administrator. An owner 
or operator who wishes to request a change in a time period or postmark 
deadline for a particular requirement shall request the adjustment in 
writing as soon as practicable before the subject activity is required 
to take place. The owner or operator shall include in the request 
whatever information he or she considers useful to convince the 
Administrator that an adjustment is warranted.
    (3) If, in the Administrator's judgment, an owner or operator's 
request for an adjustment to a particular time period or postmark 
deadline is warranted, the Administrator will approve the adjustment. 
The Administrator will notify the owner or operator in writing of 
approval or disapproval of the request for an adjustment within 15 
calendar days of receiving sufficient information to evaluate the 
request.
    (4) If the Administrator is unable to meet a specified deadline, he 
or she will notify the owner or operator of any significant delay and 
inform the owner or operator of the amended schedule.

Sec. 61.11  Waiver of compliance.

    (a) Based on the information provided in any request under 
Sec. 61.10, or other information, the Administrator may grant a waiver 
of compliance with a standard for a period not exceeding 2 years after 
the effective date of the standard.
    (b) The waiver will be in writing and will--
    (1) Identify the stationary source covered;
    (2) Specify the termination date of the waiver;
    (3) Specify dates by which steps toward compliance are to be taken; 
and
    (4) Specify any additional conditions which the Administrator 
determines necessary to assure installation of the necessary controls 
within the waiver period and to assure protection of the health of 
persons during the waiver period.
    (c) The Administrator may terminate the waiver at an earlier date 
than specified if any specification under paragraphs (b)(3) and (b)(4) 
of this section are not met.
    (d) Before denying any request for a waiver, the Administrator will 
notify the owner or operator making the request of the Administrator's 
intention to issue the denial, together with--
    (1) Notice of the information and findings on which the intended 
denial is based; and
    (2) Notice of opportunity for the owner or operator to present, 
within the time limit the Administrator specifies, additional 
information or arguments to the Administrator before final action on the 
request.
    (e) A final determination to deny any request for a waiver will be 
in writing and will set forth the specific grounds on which the denial 
is based. The final determination will be made within 60 days after 
presentation of additional information or argument; or within 60 days 
after the final date specified for

[[Page 24]]

the presentation if no presentation is made.
    (f) The granting of a waiver under this section shall not abrogate 
the Administrator's authority under section 114 of the Act.

[50 FR 46292, Nov. 7, 1985]



Sec. 61.12  Compliance with standards and maintenance requirements.

    (a) Compliance with numerical emission limits shall be determined in 
accordance with emission tests established in Sec. 61.13 or as otherwise 
specified in an individual subpart.
    (b) Compliance with design, equipment, work practice or operational 
standards shall be determined as specified in an individual subpart.
    (c) The owner or operator of each stationary source shall maintain 
and operate the source, including associated equipment for air pollution 
control, in a manner consistent with good air pollution control practice 
for minimizing emissions. Determination of whether acceptable operating 
and maintenance procedures are being used will be based on information 
available to the Administrator which may include, but is not limited to, 
monitoring results, review of operating and maintenance procedures, and 
inspection of the source.
    (d)(1) If, in the Administrator's judgment, an alternative means of 
emission limitation will achieve a reduction in emissions of a pollutant 
from a source at least equivalent to the reduction in emissions of that 
pollutant from that source achieved under any design, equipment, work 
practice or operational standard, the Administrator will publish in the 
Federal Register a notice permitting the use of the alternative means 
for purposes of compliance with the standard. The notice will restrict 
the permission to the source(s) or category(ies) of sources on which the 
alternative means will achieve equivalent emission reductions. The 
notice may condition permission on requirements related to the operation 
and maintenance of the alternative means.
    (2) Any notice under paragraph (d)(1) shall be published only after 
notice and an opportunity for a hearing.
    (3) Any person seeking permission under this subsection shall, 
unless otherwise specified in the applicable subpart, submit a proposed 
test plan or the results of testing and monitoring, a description of the 
procedures followed in testing or monitoring, and a description of 
pertinent conditions during testing or monitoring.
    (e) For the purpose of submitting compliance certifications or 
establishing whether or not a person has violated or is in violation of 
any standard in this part, nothing in this part shall preclude the use, 
including the exclusive use, of any credible evidence or information, 
relevant to whether a source would have been in compliance with 
applicable requirements if the appropriate performance or compliance 
test had been performed.

Sec. 61.13  Emission tests and waiver of emission tests.

    (a) If required to do emission testing by an applicable subpart and 
unless a waiver of emission testing is obtained under this section, the 
owner or operator shall test emissions from the source--
    (1) Within 90 days after the effective date, for an existing source 
or a new source which has an initial startup date before the effective 
date; or
    (2) Within 90 days after initial startup, for a new source which has 
an initial startup date after the effective date.
    (b) The Administrator may require an owner or operator to test 
emissions from the source at any other time when the action is 
authorized by section 114 of the Act.
    (c) The owner or operator shall notify the Administrator of the 
emission test at least 30 days before the emission test to allow the 
Administrator the opportunity to have an observer present during the 
test.
    (d) If required to do emission testing, the owner or operator of 
each new source and, at the request of the Administrator, the owner or 
operator of each existing source shall provide emission testing 
facilities as follows:
    (1) Sampling ports adequate for test methods applicable to each 
source.
    (2) Safe sampling platform(s).

[[Page 25]]

    (3) Safe access to sampling platform(s).
    (4) Utilities for sampling and testing equipment.
    (5) Any other facilities that the Administrator needs to safely and 
properly test a source.
    (e) Each emission test shall be conducted under such conditions as 
the Administrator shall specify based on design and operational 
characteristics of the source.
    (f) Unless otherwise specified in an applicable subpart, samples 
shall be analyzed and emissions determined within 30 days after each 
emission test has been completed. The owner or operator shall report the 
determinations of the emission test to the Administrator by a registered 
letter sent before the close of business on the 31st day following the 
completion of the emission test.
    (g) The owner or operator shall retain at the source and make 
available, upon request, for inspection by the Administrator, for a 
minimum of 2 years, records of emission test results and other data 
needed to determine emissions.
    (h)(1) Emission tests shall be conducted as set forth in this 
section, the applicable subpart and appendix B unless the 
Administrator--
    (i) Specifies or approves the use of a reference method with minor 
changes in methodology; or
    (ii) Approves the use of an alternative method; or
    (iii) Waives the requirement for emission testing because the owner 
or operator of a source has demonstrated by other means to the 
Administrator's satisfaction that the source is in compliance with the 
standard.
    (2) If the Administrator finds reasonable grounds to dispute the 
results obtained by an alternative method, he may require the use of a 
reference method. If the results of the reference and alternative 
methods do not agree, the results obtained by the reference method 
prevail.
    (3) The owner or operator may request approval for the use of an 
alternative method at any time, except--
    (i) For an existing source or a new source that had an initial 
startup before the effective date, any request for use of an alternative 
method during the initial emission test shall be submitted to the 
Administrator within 30 days after the effective date, or with the 
request for a waiver of compliance if one is submitted under 
Sec. 60.10(b); or
    (ii) For a new source that has an initial startup after the 
effective date, any request for use of an alternative method during the 
initial emission test shall be submitted to the Administrator no later 
than with the notification of anticipated startup required under 
Sec. 60.09.
    (i)(1) Emission tests may be waived upon written application to the 
Administrator if, in the Administrator's judgment, the source is meeting 
the standard, or the source is being operated under a waiver or 
compliance, or the owner or operator has requested a waiver of 
compliance and the Administrator is still considering that request.
    (2) If application for waiver of the emission test is made, the 
application shall accompany the information required by Sec. 61.10 or 
the notification of startup required by Sec. 61.09, whichever is 
applicable. A possible format is contained in appendix A to this part.
    (3) Approval of any waiver granted under this section shall not 
abrogate the Administrator's authority under the Act or in any way 
prohibit the Administrator from later cancelling the waiver. The 
cancellation will be made only after notice is given to the owner or 
operator of the source.

[50 FR 46292, Nov. 7, 1985]



Sec. 61.14  Monitoring requirements.

    (a) Unless otherwise specified, this section applies to each 
monitoring system required under each subpart which requires monitoring.
    (b) Each owner or operator shall maintain and operate each 
monitoring system as specified in the applicable subpart and in a manner 
consistent with good air pollution control practice for minimizing 
emissions. Any unavoidable breakdown or malfunction of the monitoring 
system should be repaired or adjusted as soon as practicable after its 
occurrence. The Administrator's determination of whether acceptable 
operating and maintenance procedures are being used will be based on 
information which may include, but

[[Page 26]]

not be limited to, review of operating and maintenance procedures, 
manufacturer recommendations and specifications, and inspection of the 
monitoring system.
    (c) When required by the applicable subpart, and at any other time 
the Administrator may require, the owner or operator of a source being 
monitored shall conduct a performance evaluation of the monitoring 
system and furnish the Administrator with a copy of a written report of 
the results within 60 days of the evaluation. Such a performance 
evaluation shall be conducted according to the applicable specifications 
and procedures described in the applicable subpart. The owner or 
operator of the source shall furnish the Administrator with written 
notification of the date of the performance evaluation at least 30 days 
before the evaluation is to begin.
    (d) When the effluents from a single source, or from two or more 
sources subject to the same emission standards, are combined before 
being released to the atmosphere, the owner or operator shall install a 
monitoring system on each effluent or on the combined effluent. If two 
or more sources are not subject to the same emission standards, the 
owner or operator shall install a separate monitoring system on each 
effluent, unless otherwise specified. If the applicable standard is a 
mass emission standard and the effluent from one source is released to 
the atmosphere through more than one point, the owner or operator shall 
install a monitoring system at each emission point unless the 
installation of fewer systems is approved by the Administrator.
    (e) The owner or operator of each monitoring system shall reduce the 
monitoring data as specified in each applicable subpart. Monitoring data 
recorded during periods of unavoidable monitoring system breakdowns, 
repairs, calibration checks, and zero and span adjustments shall not be 
included in any data average.
    (f) The owner or operator shall maintain records of monitoring data, 
monitoring system calibration checks, and the occurrence and duration of 
any period during which the monitoring system is malfunctioning or 
inoperative. These records shall be maintained at the source for a 
minimum of 2 years and made available, upon request, for inspection by 
the Administrator.
    (g)(1) Monitoring shall be conducted as set forth in this section 
and the applicable subpart unless the Administrator--
    (i) Specifies or approves the use of the specified monitoring 
requirements and procedures with minor changes in methodology; or
    (ii) Approves the use of alternatives to any monitoring requirements 
or procedures.
    (2) If the Administrator finds reasonable grounds to dispute the 
results obtained by an alternative monitoring method, the Administrator 
may require the monitoring requirements and procedures specified in this 
part.

[50 FR 46293, Nov. 7, 1985]



Sec. 61.15  Modification.

    (a) Except as provided under paragraph (d) of this section, any 
physical or operational change to a stationary source which results in 
an increase in the rate of emission to the atmosphere of a hazardous 
pollutant to which a standard applies shall be considered a 
modification.
    (b) Upon modification, an existing source shall become a new source 
for each hazardous pollutant for which the rate of emission to the 
atmosphere increases and to which a standard applies.
    (c) Emission rate shall be expressed as kg/hr of any hazardous 
pollutant discharged into the atmosphere for which a standard is 
applicable. The Administrator shall use the following to determine the 
emission rate:
    (1) Emission factors as specified in the background information 
document (BID) for the applicable standard, or in the latest issue of 
``Compilation of Air Pollutant Emission Factors,'' EPA Publication No. 
AP-42, or other emission factors determined by the Administrator to be 
superior to AP-42 emission factors, in cases where use of emission 
factors demonstrates that the emission rate will clearly increase or 
clearly not increase as a result of the physical or operational change.
    (2) Material balances, monitoring data, or manual emission tests in 
cases

[[Page 27]]

where use of emission factors, as referenced in paragraph (c)(1) of this 
section, does not demonstrate to the Administrator's satisfaction that 
the emission rate will clearly increase or clearly not increase as a 
result of the physical or operational change, or where an interested 
person demonstrates to the Administrator's satisfaction that there are 
reasonable grounds to dispute the result obtained by the Administrator 
using emission factors. When the emission rate is based on results from 
manual emission tests or monitoring data, the procedures specified in 
appendix C of 40 CFR part 60 shall be used to determine whether an 
increase in emission rate has occurred. Tests shall be conducted under 
such conditions as the Administrator shall specify to the owner or 
operator. At least three test runs must be conducted before and at least 
three after the physical or operational change. If the Administrator 
approves, the results of the emission tests required in Sec. 61.13(a) 
may be used for the test runs to be conducted before the physical or 
operational change. All operating parameters which may affect emissions 
must be held constant to the maximum degree feasible for all test runs.
    (d) The following shall not, by themselves, be considered 
modifications under this part:
    (1) Maintenance, repair, and replacement which the Administrator 
determines to be routine for a source category.
    (2) An increase in production rate of a stationary source, if that 
increase can be accomplished without a capital expenditure on the 
stationary source.
    (3) An increase in the hours of operation.
    (4) Any conversion to coal that meets the requirements specified in 
section 111(a)(8) of the Act.
    (5) The relocation or change in ownership of a stationary source. 
However, such activities must be reported in accordance with 
Sec. 61.10(c).

Sec. 61.17  State authority.

    (a) This part shall not be construed to preclude any State or 
political subdivision thereof from--
    (1) Adopting and enforcing any emission limiting regulation 
applicable to a stationary source, provided that such emission limiting 
regulation is not less stringent than the standards prescribed under 
this part; or
    (2) Requiring the owner or operator of a stationary source to obtain 
permits, licenses, or approvals prior to initiating construction, 
modification, or operation of the source.

Sec. 61.19  Circumvention.

    No owner or operator shall build, erect, install, or use any article 
machine, equipment, process, or method, the use of which conceals an 
emission which would otherwise constitute a violation of an applicable 
standard. Such concealment includes, but is not limited to, the use of 
gaseous dilutants to achieve compliance with a visible emissions 
standard, and the piecemeal carrying out of an operation to avoid 
coverage by a standard that applies only to operations larger than a 
specified size.

available, for inspection by the Administrator, for a minimum of 2 
years.
    (c) Mercury chlor-alkali plants--cell room ventilation system. (1) 
Stationary sources using mercury chlor-alkali cells may test cell room 
emissions in accordance with paragraph (c)(2) of this section or 
demonstrate compliance with paragraph (c)(4) of this section and assume 
ventilation emissions of 1,300 gms/day of mercury.
    (2) Unless a waiver of emission testing is obtained under 
Sec. 61.13, each owner or operator shall pass all cell room air in force 
gas streams through stacks suitable for testing and shall test emissions 
from the source according to Method 101 in appendix B to this part. The 
emission test shall be performed--
    (i) Within 90 days of the effective date in the case of an existing 
source or a new source which has an initial startup date preceding the 
effective date; or
    (ii) Within 90 days of startup in the case of a new source which did 
not have an initial startup date preceding the effective date.
    (3) The Administrator shall be notified at least 30 days prior to an 
emission test, so that he may at his option observe the test.
    (4) An owner or operator may carry out approved design, maintenance, 
and housekeeping practices. A list of approved practices is provided in 
appendix A of ``Review of National Emission Standards for Mercury,'' 
EPA-450/3-84-014a, December 1984. Copies are available from EPA's 
Central Docket Section, Docket item number A-84-41, III-B-1.
    (d) Sludge incineration and drying plants. (1) Unless a waiver of 
emission testing is obtained under Sec. 61.13, each owner or operator of 
a source subject to the standard in Sec. 61.52(b) shall test emissions 
from that source. Such tests shall be conducted in accordance with the 
procedures set forth either in paragraph (d) of this section or in 
Sec. 61.54.
    (2) Method 101A in appendix B to this part shall be used to test

of these regulations in the case of an existing source or a new source 
which has an initial startup date preceding the effective date.
    (ii) The test shall be performed within 90 days of startup in the 
case of a new source which did not have an initial startup date 
preceding the effective date.
    (3) The Administrator shall be notified at least 30 days prior to an 
emission test, so that he may at his option observe the test.
    (4) Samples shall be taken over such a period or periods as are 
necessary to determine accurately the maximum emissions which will occur 
in a 24-hour period. No changes shall be made in the operation which 
would potentially increase emissions above the level determined by the 
most recent stack test, until the new emission level has been estimated 
by calculation and the results reported to the Administrator.
    (5) All samples shall be analyzed and mercury emissions shall be 
determined within 30 days after the stack test. Each determination shall 
be reported to the Administrator by a registered letter dispatched 
within 15 calendar days following the date such determination is 
completed.
    (6) Records of emission test results and other data needed to 
determine total emissions shall be retained at the source and shall be

the procedures specified in this section.
    (1) A sludge test shall be conducted within 90 days of the effective 
date of these regulations in the case of an existing source or a new 
source which has an initial startup date preceding the effective date; 
or
    (2) A sludge test shall be conducted within 90 days of startup in 
the case of a new source which did not have an initial startup date

shall be performed according to paragraph (c)(3) of this section.
    (1) The sludge shall be sampled according to Method 105--
Determination of Mercury in Wastewater Treatment Plant Sewage Sludges. A 
total of three composite samples shall be obtained within an operating 
period of 24 hours. When the 24-hour operating period is not continuous, 
the total sampling period shall not exceed 72 hours after the first grab 
sample is obtained. Samples shall not be exposed to any condition that 
may result in mercury contamination or loss.
    (2) The maximum 24-hour period sludge incineration or drying rate 
shall be determined by use of a flow rate measurement device that can 
measure the mass rate of sludge charged to the incinerator or dryer with 
an accuracy of plus-minus5 percent over its operating range. 
Other methods of measuring sludge mass charging rates may be used if 
they have received prior approval by the Administrator.
    (3) The sampling, handling, preparation, and analysis of sludge 
samples shall be accomplished according to Method 105 in appendix B of 
this part.

sludge test has been conducted which would potentially increase 
emissions above the level determined by the most recent sludge test, 
until the new emission level has been estimated by calculation and the 
results reported to the Administrator.
    (f) All sludge samples shall be analyzed for mercury content within 
30 days after the sludge sample is collected. Each determination shall 
be reported to the Administrator by a registered letter dispatched 
within 15 calendar days following the date such determination is 
completed.

Sec. 61.55  Monitoring of emissions and operations.

    (a) Wastewater treatment plant sludge incineration and drying 
plants. All the sources for which mercury emissions exceed 1,600 g per 
24-hour period, demonstrated either by stack sampling according to 
Sec. 61.53 or sludge sampling according to Sec. 61.54, shall monitor 
mercury emissions at intervals of at least once per year by use of 
Method 105 of appendix B or the procedures specified

[[Page 37]]

in Sec. 61.53 (d) (2) and (4). The results of monitoring shall be 
reported and retained according to Sec. 61.53(d) (5) and (6) or 
Sec. 61.54 (f) and (g).
    (b) Mercury cell chlor-alkali plants--hydrogen and end-box 
ventilation gas streams. (1) The owner or operator of each mercury cell 
chlor-alkali plant shall, within 1 year of the date of publication of 
these amendments or within 1 year of startup for a plant with initial 
startup after the date of publication, perform a mercury emission test 
that demonstrates compliance with the emission limits in Sec. 61.52, on 
the hydrogen stream by Reference Method 102 and on the end-box stream by 
Reference Method 101 for the purpose of establishing limits for 
parameters to be monitored.
    (2) During tests specified in paragraph (b)(1) of this section, the 
following control device parameters shall be monitored, except as 
provided in paragraph (c) of this section, and recorded manually or 
automatically at least once every 15 minutes:
    (i) The exit gas temperature from uncontrolled streams;
    (ii) The outlet temperature of the gas stream for the final (i.e., 
the farthest downstream) cooling system when no control devices other 
than coolers and demisters are used;
    (iii) The outlet temperature of the gas stream from the final 
cooling system when the cooling system is followed by a molecular sieve 
or carbon adsorber;
    (iv) Outlet concentration of available chlorine, pH, liquid flow 
rate, and inlet gas temperature of chlorinated brine scrubbers and 
hypochlorite scrubbers;
    (v) The liquid flow rate and exit gas temperature for water 
scrubbers;
    (vi) The inlet gas temperature of carbon adsorption systems; and
    (vii) The temperature during the heating phase of the regeneration 
cycle for carbon adsorbers or molecular sieves.
    (3) The recorded parameters in paragraphs (b)(2)(i) through 
(b)(2)(vi) of this section shall be averaged over the test period (a 
minimum of 6 hours) to provide an average number. The highest 
temperature reading that is measured in paragraph (b)(2)(vii) of this 
section is to be identified as the reference temperature for use in 
paragraph (b)(6)(ii) of this section.
    (4)(i) Immediately following completion of the emission tests 
specified in paragraph (b)(1) of this section, the owner or operator of 
a mercury cell chlor-alkali plant shall monitor and record manually or 
automatically at least once per hour the same parameters specified in 
paragraphs (b)(2)(i) through (b)(2)(vi) of this section.
    (ii) Immediately following completion of the emission tests 
specified in paragraph (b)(1) of this section, the owner or operator 
shall monitor and record manually or automatically, during each heating 
phase of the regeneration cycle, the temperature specified in paragraph 
(b)(2)(vii) of this section.
    (5) Monitoring devices used in accordance with paragraphs (b)(2) and 
(b)(4) of this section shall be certified by their manufacturer to be 
accurate to within 10 percent, and shall be operated, maintained, and 
calibrated according to the manufacturer's instructions. Records of the 
certifications and calibrations shall be retained at the chlor-alkali 
plant and made available for inspection by the Administrator as follows: 
Certification, for as long as the device is used for this purpose; 
calibration for a minimum of 2 years.
    (6)(i) When the hourly value of a parameter monitored in accordance 
with paragraph (b)(4)(i) of this section exceeds, or in the case of 
liquid flow rate and available chlorine falls below the value of that 
same parameter determined in paragraph (b)(2) of this section for 24 
consecutive hours, the Administrator is to be notified within the next 
10 days.
    (ii) When the maximum hourly value of the temperature measured in 
accordance with paragraph (b)(4)(ii) of this section is below the 
reference temperature recorded according to paragraph (b)(3) of this 
section for three consecutive regeneration cycles, the Administrator is 
to be notified within the next 10 days.
    (7) Semiannual reports shall be submitted to the Administrator 
indicating the time and date on which the hourly value of each parameter 
monitored according to paragraphs (b)(4)(i) and (b)(4)(ii) of this 
section fell outside the

[[Page 38]]

value of that same parameter determined under paragraph (b)(3) of this 
section; and corrective action taken, and the time and date of the 
corrective action. Parameter excursions will be considered unacceptable 
operation and maintenance of the emission control system. In addition, 
while compliance with the emission limits is determined primarily by 
conducting a performance test according to the procedures in 
Sec. 61.53(b), reports of parameter excursions may be used as evidence 
in judging the duration of a violation that is determined by a 
performance test.
    (8) Semiannual reports required in paragraph (b)(7) of this section 
shall be submitted to the Administrator on September 15 and March 15 of 
each year. The first semiannual report is to be submitted following the 
first full 6 month reporting period. The semiannual report due on 
September 15 (March 15) shall include all excursions monitored through 
August 31 (February 28) of the same calendar year.
    (c) As an alternative to the monitoring, recordkeeping, and 
reporting requirements in paragraphs (b)(2) through (8) of this section, 
an owner or operator may develop and submit for the Administrator's 
review and approval a plant-specific monitoring plan. To be approved, 
such a plan must ensure not only compliance with the emission limits of 
Sec. 61.52(a) but also proper operation and maintenance of emissions 
control systems. Any site-specific monitoring plan submitted must, at a 
minimum, include the following:
    (1) Identification of the critical parameter or parameters for the 
hydrogen stream and for the end-box ventilation stream that are to be 
monitored and an explanation of why the critical parameter(s) selected 
is the best indicator of proper control system performance and of 
mercury emission rates.
    (2) Identification of the maximum or minimum value of each parameter 
(e.g., degrees temperature, concentration of mercury) that is not to be 
exceeded. The level(s) is to be directly correlated to the results of a 
performance test, conducted no more than 180 days prior to submittal of 
the plan, when the facility was in compliance with the emission limits 
of Sec. 61.52(a).
    (3) Designation of the frequency for recording the parameter 
measurements, with justification if the frequency is less than hourly. A 
longer recording frequency must be justified on the basis of the amount 
of time that could elapse during periods of process or control system 
upsets before the emission limits would be exceeded, and consideration 
is to be given to the time that would be necessary to repair the 
failure.
    (4) Designation of the immediate actions to be taken in the event of 
an excursion beyond the value of the parameter established in 2.
    (5) Provisions for reporting, semiannually, parameter excursions and 
the corrective actions taken, and provisions for reporting within 10 
days any significant excursion.
    (6) Identification of the accuracy of the monitoring device(s) or of 
the readings obtained.
    (7) Recordkeeping requirements for certifications and calibrations.
    (d) Mercury cell chlor-alkali plants--cell room ventilation system. 
(1) Stationary sources determining cell room emissions in accordance 
with Sec. 61.53(c)(4) shall maintain daily records of all leaks or 
spills of mercury. The records shall indicate the amount, location, 
time, and date the leaks or spills occurred, identify the cause of the 
leak or spill, state the immediate steps taken to minimize mercury 
emissions and steps taken to prevent future occurrences, and provide the 
time and date on which corrective steps were taken.
    (2) The results of monitoring shall be recorded, retained at the 
source, and made available for inspection by the Administrator for a 
minimum of 2 years.

vinyl chloride in each exhaust gas stream from any equipment used in 
vinyl chloride formation and/or purification is not to exceed 10 ppm 
(average for 3-hour period), except as provided in Sec. 61.65(a). This 
requirement does not preclude combining of exhaust gas streams provided 
the combined steam is ducted through a control system from which the 
concentration of vinyl chloride in the exhaust gases does not exceed 10 
ppm, or equivalent as provided in Sec. 61.66. This requirement does not 
apply to equipment that has been opened, is out of operation, and met 
the requirement in Sec. 61.65(b)(6)(i) before being opened.

Sec. 61.64  Emission standard for polyvinyl chloride plants.

    An owner or operator of a polyvinyl chloride plant shall comply with 
the requirements of this section and Sec. 61.65.
    (a) Reactor. The following requirements apply to reactors:
    (1) The concentration of vinyl chloride in each exhaust gas stream 
from each reactor is not to exceed 10 ppm (average for 3-hour period), 
except as provided in paragraph (a)(2) of this section and 
Sec. 61.65(a).
    (2) The reactor opening loss from each reactor is not to exceed 0.02 
g vinyl chloride/kg (0.00002 lb vinyl chloride/lb) of polyvinyl chloride 
product, except as provided in paragraph (f)(1) of this section, with 
the product determined on a dry solids basis. This requirement does not 
apply to prepolymerization reactors in the bulk process. This 
requirement does apply to postpolymerization reactors in the bulk 
process, where the product means the gross product of prepolymerization 
and postpolymerization.
    (3) Manual vent valve discharge. Except for an emergency manual vent 
valve discharge, there is to be no discharge to the atmosphere from any 
manual vent valve on a polyvinyl chloride reactor in vinyl chloride 
service. An emergency manual vent valve discharge means a discharge to 
the atmosphere which could not have been avoided by taking measures to 
prevent the discharge. Within 10 days of any discharge to the atmosphere 
from any manual vent valve, the owner or operator of the source from 
which the discharge occurs shall submit to the Administrator a report in 
writing containing information on the source, nature and cause of the 
discharge, the date and time of the discharge, the approximate total 
vinyl chloride loss during the discharge, the method used for

Sec. 61.65  Emission standard for ethylene dichloride, vinyl chloride and polyvinyl chloride plants.

    An owner or operator of an ethylene dichloride, vinyl chloride, and/
or polyvinyl chloride plant shall comply with the requirements of this 
section.
    (a) Relief valve discharge. Except for an emergency relief 
discharge, and except as provided in Sec. 61.65(d), there is to be no 
discharge to the atmosphere from any relief valve on any equipment in 
vinyl chloride service. An emergency relief discharge means a discharge 
which could not have been avoided by taking measures to prevent the 
discharge. Within 10 days of any relief valve discharge, except for 
those subject to Sec. 61.65(d), the owner or operator of the source from 
which the relief valve discharge occurs shall submit to the 
Administrator a report in writing containing information on the source, 
nature and cause of the discharge, the date and time of the discharge, 
the approximate total vinyl chloride loss during the discharge, the 
method used for determining the vinyl chloride loss (the calculation of 
the vinyl chloride loss), the action that was taken to prevent the 
discharge, and measures adopted to prevent future discharges.
    (b) Fugitive emission sources--(1) Loading and unloading lines. 
Vinyl chloride emissions from loading and unloading lines in vinyl 
chloride service which are opened to the atmosphere after each loading 
or unloading operation are to be minimized as follows:
    (i) After each loading or unloading operation and before opening a 
loading or unloading line to the atmosphere, the quantity of vinyl 
chloride in all parts of each loading or unloading line that are to be 
opened to the atmosphere is to be reduced so that the parts combined 
contain no greater than 0.0038 m 3 (0.13 ft 3) of 
vinyl chloride, at standard temperature and pressure; and
    (ii) Any vinyl chloride removed from a loading or unloading line in 
accordance with paragraph (b)(1)(i) of this section is to be ducted 
through a control system from which the concentration of vinyl chloride 
in the exhaust gases does not exceed 10 ppm (average for 3-hour period), 
or equivalent as provided in Sec. 61.66.
    (2) Slip gauges. During loading or unloading operations, the vinyl 
chloride emissions from each slip gauge in vinyl chloride service are to 
be minimized by ducting any vinyl chloride discharged from the slip 
gauge through a control system from which the concentration of vinyl 
chloride in the exhaust gases does not exceed 10 ppm (average for 3-hour 
period), or equivalent as provided in Sec. 61.66.
    (3) Leakage from pump, compressor, and agitator seals:
    (i) Rotating pumps. Vinyl chloride emissions from seals on all 
rotating pumps in vinyl chloride service are to be minimized by 
installing sealless pumps, pumps with double mechanical seals or 
equivalent as provided in Sec. 61.66. If double mechanical seals are 
used, vinyl chloride emissions from the seals are to be minimized by 
maintaining the pressure between the two seals so that any leak that 
occurs is into the pump; by ducting any vinyl chloride between the two 
seals through a control system from which the concentration of vinyl 
chloride in the exhaust gases does not exceed 10 ppm; or equivalent as 
provided in Sec. 61.66. Compliance with the provisions of 40 CFR part 61 
subpart V demonstrates compliance with the provisions of this paragraph.
    (ii) Reciprocating pumps. Vinyl chloride emissions from seals on all 
reciprocating pumps in vinyl chloride service are to be minimized by 
installing double outboard seals, or equivalent as provided in 
Sec. 61.66. If double outboard seals are used, vinyl chloride emissions 
from the seals are to be minimized by maintaining the pressure between 
the two seals so that any leak that occurs is into the pump; by ducting 
any vinyl chloride between the two seals through a control system from 
which the concentration of vinyl chloride in the exhaust gases does not 
exceed 10 ppm; or equivalent as provided in Sec. 61.66. Compliance with 
the provisions of 40 CFR part 61 subpart V demonstrates compliance with 
the provisions of this paragraph.
    (iii) Rotating compressor. Vinyl chloride emissions from seals on 
all rotating compressors in vinyl chloride service are to be minimized 
by installing compressors with double mechanical seals, or equivalent as 
provided in

[[Page 44]]

Sec. 61.66. If double mechanical seals are used, vinyl chloride 
emissions from the seals are to be minimized by maintaining the pressure 
between the two seals so that any leak that occurs is into the 
compressor; by ducting any vinyl chloride between the two seals through 
a control system from which the concentration of vinyl chloride in the 
exhaust gases does not exceed 10 ppm; or equivalent as provided in 
Sec. 61.66. Compliance with the provisions of 40 CFR part 61 subpart V 
demonstrates compliance with the provisions of this paragraph.
    (iv) Reciprocating compressors. Vinyl chloride emissions from seals 
on all reciprocating compressors in vinyl chloride service are to be 
minimized by installing double outboard seals, or equivalent as provided 
in Sec. 61.66. If double outboard seals are used, vinyl chloride 
emissions from the seals are to be minimized by maintaining the pressure 
between the two seals so that any leak that occurs is into the 
compressor; by ducting any vinyl chloride between the two seals through 
a control system from which concentration of vinyl chloride in the 
exhaust gases does not exceed 10 ppm; or equivalent as provided in 
Sec. 61.66. Compliance with the provisions of 40 CFR part 61 subpart V 
demonstrates compliance with the provisions of this paragraph.
    (v) Agitator. Vinyl chloride emissions from seals on all agitators 
in vinyl chloride service are to be minimized by installing agitators 
with double mechanical seals, or equivalent as provided in Sec. 61.66. 
If double mechanical seals are used, vinyl chloride emissions from the 
seals are to be minimized by maintaining the pressure between the two 
seals so that any leak that occurs is into the agitated vessel; by 
ducting any vinyl chloride between the two seals through a control 
system from which the concentration of vinyl chloride in the exhaust 
gases does not exceed 10 ppm; or equivalent as provided in Sec. 61.66.
    (4) Leaks from relief valves. Vinyl chloride emissions due to leaks 
from each relief valve on equipment in vinyl chloride service shall 
comply with Sec. 61.242-4 of subpart V of this part.
    (5) Manual venting of gases. Except as provided in Sec. 61.64(a)(3), 
all gases which are manually vented from equipment in vinly chloride 
service are to be ducted through a control system from which the 
concentration of vinyl chloride in the exhaust gases does not exceed 10 
ppm (average for 3-hour period); or equivalent as provided in 
Sec. 61.66.
    (6) Opening of equipment. Vinyl chloride emissions from opening of 
equipment (excluding crude, intermediate, and final EDC storage tanks, 
but including prepolymerization reactors used in the manufacture of bulk 
resins and loading or unloading lines that are not opened to the 
atmosphere after each loading or unloading operation) are to be 
minimized follows:
    (i) Before opening any equipment for any reason, the quantity of 
vinyl chloride which is contained therein is to be reduced to an amount 
which occupies a volume of no more than 2.0 percent of the equipment's 
containment volume or 0.0950 cubic meters (25 gallons), whichever is 
larger, at standard temperature and pressure.
    (ii) Any vinyl chloride removed from the equipment in accordance 
with paragraph (b)(6)(i) of this section is to be ducted through a 
control system from which the concentration of vinyl chloride in the 
exhaust gases does not exceed 10 ppm (average for 3-hour period); or 
equivalent as provided in Sec. 61.66.
    (7) Samples. Unused portions of samples containing at least 10 
percent by weight vinyl chloride are to be returned to the process or 
destroyed in a control device from which concentration of vinyl chloride 
in the exhaust gas does not exceed 10 ppm (average for 3-hour period) or 
equivalent as provided in Sec. 61.66. Sampling techniques are to be such 
that sample containers in vinyl chloride service are purged into a 
closed process system. Compliance with the provisions of 40 CFR part 61 
subpart V demonstrates compliance with the provisions of this paragraph.
    (8) Leak detection and elimination. Vinyl chloride emissions due to 
leaks from equipment in vinyl chloride service are to be minimized as 
follows:
    (i) A reliable and accurate vinyl chloride monitoring system shall 
be operated for detection of major leaks and identification of the 
general area of the plant where a leak is located. A vinyl

[[Page 45]]

chloride monitoring system means a device which obtains air samples from 
one or more points on a continuous sequential basis and analyzes the 
samples with gas chromatography or, if the owner or operator assumes 
that all hydrocarbons measured are vinyl chloride, with infrared 
spectrophotometry, flame ion detection, or an equivalent or alternative 
method. The vinyl chloride monitoring system shall be operated according 
to a program developed by the plant owner or operator. The owner or 
operator shall submit a description of the program to the Administrator 
within 45 days of the effective date of these regulations, unless a 
waiver of compliance is granted under Sec. 61.11, or the program has 
been approved and the Administrator does not request a review of the 
program. Approval of a program will be granted by the Administrator 
provided he finds:
    (A) The location and number of points to be monitored and the 
frequency of monitoring provided for in the program are acceptable when 
they are compared with the number of pieces of equipment in vinyl 
chloride service and size and physical layout of the plant.
    (B) It contains a definition of leak which is acceptable when 
compared with the background concentrations of vinyl chloride in the 
areas of the plant to be monitored by the vinyl chloride monitoring 
system. Measurements of background concentrations of vinyl chloride in 
the areas of the plant to be monitored by the vinyl chloride monitoring 
system are to be included with the description of the program. The 
definition of leak for a given plant may vary among the different areas 
within the plant and is also to change over time as background 
concentrations in the plant are reduced.
    (C) It contains an acceptable plan of action to be taken when a leak 
is detected.
    (D) It provides for an acceptable calibration and maintenance 
schedule for the vinyl chloride monitoring system and portable 
hydrocarbon detector. For the vinyl chloride monitoring system, a daily 
span check is to be conducted with a concentration of vinyl chloride 
equal to the concentration defined as a leak according to paragraph 
(b)(8)(i)(B) of this section. The calibration is to be done with either:
    (1) A calibration gas mixture prepared from the gases specified in 
sections 5.2.1. and 5.2.2. of Test Method 106 and in accordance with 
section 7.1 of Test Method 106, or
    (2) A calibration gas cylinder standard containing the appropriate 
concentration of vinyl chloride. The gas composition of the calibration 
gas cylinder standard is to have been certified by the manufacturer. The 
manufacturer must have recommended a maximum shelf life for each 
cylinder so that the concentration does not change greater than 
5 percent from the certified value. The date of gas cylinder 
preparation, certified vinyl chloride concentration, and recommended 
maximum self life must have been affixed to the cylinder before shipment 
from the manufacturer to the buyer. If a gas chromatograph is used as 
the vinyl chloride monitoring system, these gas mixtures may be directly 
used to prepare a chromatograph calibration curve as described in 
section 7.3 of Test Method 106. The requirements in section 5.2.3.1. and 
5.2.3.2. of Test Method 106 for certification of cylinder standards and 
for establishment and verification of calibration standards are to be 
followed.
    (ii) For each process unit subject to this subpart, a formal leak 
detection and repair program shall be implemented consistent with 
subpart V of this part, except as provided in paragraph (b)(8)(iii) of 
this section. This program is to be implemented within 90 days of the 
effective date of these regulations, unless a waiver of compliance is 
granted under Sec. 61.11. Except as provided in paragraph (b)(8)(ii)(E) 
of this section, an owner or operator shall be exempt from Sec. 61.242-
1(d), Sec. 61.242-7 (a), (b), and (c), Sec. 61.246, and Sec. 61.247 of 
subpart V of this part for any process unit in which the percentage of 
leaking valves is demonstrated to be less than 2.0 percent, as 
determined in accordance with the following:
    (A) A performance test as specified in paragraph (b)(8)(ii)(B) of 
this section shall be conducted initially within 90 days of the 
effective date of these regulations, annually, and at times requested by 
the Administrator.

[[Page 46]]

    (B) For each performance test, a minimum of 200 or 90 percent, 
whichever is less, of the total valves in VOC service (as defined in 
Sec. 60.481 of subpart VV of part 60) within the process unit shall be 
randomly selected and monitored within 1 week by the methods specified 
in Sec. 61.245(b) of this part. If an instrument reading of 10,000 ppm 
or greater is measured, a leak is detected. The leak percentage shall be 
determined by dividing the number of valves in VOC service for which 
leaks are detected by the number of tested valves in VOC service.
    (C) If a leak is detected, it shall be repaired in accordance with 
Sec. 61.242-7 (d) and (e) of subpart V of this part.
    (D) The results of the performance test shall be submitted in 
writing to the Administrator in the first quarterly report following the 
performance test as part of the reporting requirements of Sec. 61.70.
    (E) Any process unit in which the percentage of leaking valves is 
found to be greater than 2.0 percent according to the performance test 
prescribed in paragraph (b)(8)(ii)(B) of this section must comply with 
all provisions of subpart V of this part within 90 days.
    (iii) Open-ended valves or lines located on multiple service process 
lines which operate in vinyl chloride service less than 10 percent of 
the time are exempt from the requirements of Sec. 61.242-6 of subpart V, 
provided the open-ended valves or lines are addressed in the monitoring 
system required by paragraph (b)(8)(i) of this section. The 
Administrator may apply this exemption to other existing open-ended 
valves or lines that are demonstrated to require significant retrofit 
cost to comply with the requirements of Sec. 61.242-6 of subpart V.
    (9) Inprocess wastewater. Vinyl chloride emissions to the atmosphere 
from inprocess wastewater are to be reduced as follows:
    (i) The concentration of vinyl chloride in each inprocess wastewater 
stream containing greater than 10 ppm vinyl chloride measured 
immediately as it leaves a piece of equipment and before being mixed 
with any other inprocess wastewater stream is to be reduced to no more 
than 10 ppm by weight before being mixed with any other inprocess 
wastewater stream which contains less than 10 ppm vinyl chloride; before 
being exposed to the atmosphere; before being discharged to a wastewater 
treatment process; or before being discharged untreated as a wastewater. 
This paragraph does apply to water which is used to displace vinyl 
chloride from equipment before it is opened to the atmosphere in 
accordance with Sec. 61.64(a)(2) or paragraph (b)(6) of this section, 
but does not apply to water which is used to wash out equipment after 
the equipment has already been opened to the atmosphere in accordance 
with Sec. 61.64(a)(2) or paragraph (b)(6) of this section.
    (ii) Any vinyl chloride removed from the inprocess wastewater in 
accordance with paragraph (b)(9)(i) of this section is to be ducted 
through a control system from which the concentration of vinyl chloride 
in the exhaust gases does not exceed 10 ppm (average for 3-hour period); 
or equivalent as provided in Sec. 61.66.
    (c) The requirements in paragraphs (b)(1), (b)(2), (b)(5), (b)(6), 
(b)(7) and (b)(8) of this section are to be incorporated into a standard 
operating procedure, and made available upon request for inspection by 
the Administrator. The standard operating procedure is to include 
provisions for measuring the vinyl chloride in equipment 4.75 m\3\ (1255 
gal) in volume for which an emission limit is prescribed in 
Sec. 61.65(b)(6)(i) after opening the equipment and using Test Method 
106, a portable hydrocarbon detector, or an alternative method. The 
method of measurement is to meet the requirements in 
Sec. 61.67(g)(5)(i)(A) or (g)(5)(i)(B).
    (d) A RVD that is ducted to a control device that is continually 
operating while emissions from the release are present at the device is 
subject to the following requirements:
    (1) A discharge from a control device other than a flare shall not 
exceed 10 ppm (average over a 3-hour period) as determined by the 
continuous emission monitor system required under Sec. 61.68. Such a 
discharge is subject to the requirements of Sec. 61.70.
    (2) For a discharge routed to a flare, the flare shall comply with 
the requirements of Sec. 60.18.

[[Page 47]]

    (i) Flare operations shall be monitored in accordance with the 
requirements of Secs. 60.18(d) and 60.18(f)(2). For the purposes of 
Sec. 60.18(d), the volume and component concentration of each relief 
valve discharge shall be estimated and calculation shall be made to 
verify ongoing compliance with the design and operating requirements of 
Secs. 60.18 (c)(3) through (c)(6). If more than one relief valve is 
discharged simultaneously to a single flare, these calculations shall 
account for the cumulative effect of all such relief valve discharges. 
These calculations shall be made and reported quarterly for all 
discharges within the quarter. Failure to comply with any of the 
requirements of this paragraph will be a violation of Sec. 61.65(d)(2). 
Monitoring for the presence of a flare pilot flame shall be conducted in 
accordance with Sec. 60.18(f)(2). If the results of this monitoring or 
any other information shows that the pilot flame is not present 100 
percent of the time during which a relief valve discharge is routed to 
the flare, the relief valve discharge is subject to the provisions of 
Sec. 61.65(a).
    (ii) A report describing the flare design shall be provided to the 
Administrator not later than 90 days after the adoption of this 
provision or within 30 days of the installation of a flare system for 
control of relief valve discharge whichever is later. The flare design 
report shall include calculations based upon expected relief valve 
discharge component concentrations and net heating values (for PVC this 
calculation shall be based on values expected if a release occurred at 
the instant the polymerization starts); and estimated maximum exit 
velocities based upon the design throat capacity of the gas in the 
relief valve.

Sec. 61.66  Equivalent equipment and procedures.

    Upon written application from an owner or operator, the 
Administrator may approve use of equipment or procedures which have been 
demonstrated to his satisfaction to be equivalent in terms of reducing 
vinyl chloride emissions to the atmosphere to those prescribed for 
compliance with a specific paragraph of this subpart.

[51 FR 34912, Sept. 30, 1986]



Sec. 61.67  Emission tests.

    (a) Unless a waiver of emission testing is obtained under 
Sec. 61.13, the owner or operator of a source to which this subpart 
applies shall test emissions from the source,
    (1) Within 90 days of the effective date in the case of an existing 
source or a new source which has an initial startup date preceding the 
effective date, or
    (2) Within 90 days of startup in the case of a new source, initial 
startup of which occurs after the effective date.
    (b) The owner or operator shall provide the Administrator at least 
30 days prior notice of an emission test to afford the Administrator the 
opportunity to have an observer present during the test.
    (c) Any emission test is to be conducted while the equipment being 
tested is operating at the maximum production rate at which the 
equipment will be operated and under other relevant conditions as may be 
specified by the Administrator based on representative performance of 
the source.
    (d) [Reserved]
    (e) When at all possible, each sample is to be analyzed within 24 
hours, but in no case in excess of 72 hours of sample collection. Vinyl 
chloride emissions are to be determined within 30 days after the 
emission test. The owner or operator shall report the determinations to 
the Administrator by a registered letter dispatched before the close of 
the next business day following the determination.
    (f) The owner or operator shall retain at the plant and make 
available, upon request, for inspection by the Administrator, for a 
minimum of 3 years, records of emission test results and other data 
needed to determine emissions.
    (g) Unless otherwise specified, the owner or operator shall use test 
Test Methods in appendix B to this part for each test as required by 
paragraphs (g)(1), (g)(2), (g)(3), (g)(4), and (g)(5) of this section, 
unless an alternative

[[Page 48]]

method has been approved by the Administrator. If the Administrator 
finds reasonable grounds to dispute the results obtained by an 
alternative method, he may require the use of a reference method. If the 
results of the reference and alternative methods do not agree, the 
results obtained by the reference method prevail, and the Administrator 
may notify the owner or operator that approval of the method previously 
considered to be alternative is withdrawn. Whenever Test Method 107 is 
specified, and the conditions in Section 1.1, ``Applicability'' of 
Method 107A are met, Method 107A may be used.
    (1) Test Method 106 is to be used to determine the vinyl chloride 
emissions from any source for which an emission limit is prescribed in 
Sec. 61.62 (a) or (b) Sec. 61.63(a), or Sec. 61.64(a)(1), (b), (c), or 
(d), or from any control system to which reactor emissions are required 
to be ducted in Sec. 61.64(a)(2) or to which fugitive emissions are 
required to be ducted is Sec. 61.65(b)(1)(ii), (b)(2), (b)(5), 
(b)(6)(ii), or (b)(9)(ii).
    (i) For each run, one sample is to be collected. The sampling site 
is to be at least two stack or duct diameters downstream and one half 
diameter upstream from any flow disturbance such as a bend, expansion, 
contraction, or visible flame. For a rectangular cross section an 
equivalent diameter is to be determined from the following equation:

equivalent diameter=2 (length) (width)/length+width


The sampling point in the duct is to be at the centroid of the cross 
section. The sample is to be extracted at a rate proportional to the gas 
velocity at the sampling point. The sample is to contain a minimum 
volume of 50 liters corrected to standard conditions and is to be taken 
over a period as close to 1 hour as practicable.
    (ii) Each emission test is to consist of three runs. For the purpose 
of determining emissions, the average of results of all runs is to 
apply. The average is to be computed on a time weighted basis.
    (iii) For gas streams containing more than 10 percent oxygen the 
concentration of vinyl chloride as determined by Test Method 106 is to 
be corrected to 10 percent oxygen (dry basis) for determination of 
emissions by using the following equation:


Cb (corrected)=Cb 10.9/20.9-percent O2

where:

Cb (corrected)=The concentration of vinyl chloride in 
the exhaust gases, corrected to 10-percent oxygen.
Cb=The concentration of vinyl chloride as measured by Test 
Method 106.
20.9=Percent oxygen in the ambient air at standard conditions.
10.9=Percent oxygen in the ambient air at standard conditions, minus the 
10.0-percent oxygen to which the correction is being made.
Percent O2=Percent oxygen in the exhaust gas as measured by 
Reference Method 3 in appendix A of part 60 of this chapter.

    (iv) For those emission sources where the emission limit is 
prescribed in terms of mass rather than concentration, mass emissions in 
kg/100 kg product are to be determined by using the following equation:


CBX=[Cb(2.60) Q 10-6] [100]/Z

where:

CBX=kg vinyl chloride/100 kg product.
Cb=The concentration of vinyl chloride as measured by Test 
Method 106.
2.60=Density of vinyl chloride at one atmosphere and 20  deg.C in kg/m 
3.
Q=Volumetric flow rate in m 3/hr as determined by 
Reference Method 2 of appendix A to part 60 of this chapter.
10-6=Conversion factor for ppm.
Z=Production rate (kg/hr).

    (2) Test Method 107 or Method 601 (incorporated by reference as 
specified in Sec. 61.18) is to be used to determine the concentration of 
vinyl chloride in each inprocess wastewater stream for which an emission 
limit is prescribed in Sec. 61.65(b)(9)(i).
    (3) When a stripping operation is used to attain the emission limits 
in Sec. 61.64 (e) and (f), emissions are to be determined using Test 
Method 107 as follows:
    (i) The number of strippers (or reactors used as strippers) and 
samples and the types and grades of resin to be sampled are to be 
determined by the Administrator for each individual plant at the time of 
the test based on the plant's operation.

[[Page 49]]

    (ii) Each sample is to be taken immediately following the stripping 
operation.
    (iii) The corresponding quantity of material processed by each 
stripper (or reactor used as a stripper) is to be determined on a dry 
solids basis and by a method submitted to and approved by the 
Administrator.
    (iv) At the prior request of the Administrator, the owner or 
operator shall provide duplicates of the samples required in paragraph 
(g)(3)(i) of this section.
    (4) Where control technology other than or in addition to a 
stripping operation is used to attain the emission limit in 
Sec. 61.64(e), emissions are to be determined as follows:
    (i) Test Method 106 is to be used to determine atmospheric emissions 
from all of the process equipment simultaneously. The requirements of 
paragraph (g)(1) of this section are to be met.
    (ii) Test Method 107 is to be used to determine the concentration of 
vinyl chloride in each inprocess wastewater stream subject to the 
emission limit prescribed in Sec. 61.64(e). The mass of vinyl chloride 
in kg/100 kg product in each inprocess wastewater stream is to be 
determined by using the following equation:

CBX=[CdR10-6] [100]/Z

where:

CBX=kg vinyl chloride/100 kg product.
Cd=the concentration of vinyl chloride as measured by Test 
Method 107.
R=water flow rate in 1/hr, determined in accordance with a method which 
has been submitted to and approved by the Administrator.
10-6=Conversion factor for ppm.
Z=Production rate (kg/hr), determined in accordance with a method which 
has been submitted and approved by the Administrator.

    (5) The reactor opening loss for which an emission limit is 
prescribed in Sec. 61.64(a)(2) is to be determined. The number of 
reactors for which the determination is to be made is to be specified by 
the Administrator for each individual plant at the time of the 
determination based on the plant's operation.
    (i) Except as provided in paragraph (g)(5)(ii) of this section, the 
reactor opening loss is to be determined using the following equation:


C=W (2.60) (10 6) (Cb)/YZ

where:

C=kg vinyl chloride emissions/kg product.
W=Capacity of the reactor in m 3.
2.60=Density of vinyl chloride at one atmosphere and 20  deg.C in kg/m 
3.
10-6=Conversion factor for ppm.
Cb=ppm by volume vinyl chloride as determined by Test Method 
106 or a portable hydrocarbon detector which measures hydrocarbons with 
a sensitivity of at least 10 ppm.
Y=Number of batches since the reactor was last opened to the atmosphere.
Z=Average kg of polyvinyl chloride produced per batch in the number of 
batches since the reactor was last opened to the atmosphere.

    (A) If Method 106 is used to determine the concentration of vinyl 
chloride (Cb), the sample is to be withdrawn at a constant rate with a 
probe of sufficient length to reach the vessel bottom from the manhole. 
Samples are to be taken for 5 minutes within 6 inches of the vessel 
bottom, 5 minutes near the vessel center, and 5 minutes near the vessel 
top.
    (B) If a portable hydrocarbon detector is used to determine the 
concentration of vinyl chloride (Cb), a probe of sufficient length to 
reach the vessel bottom from the manhole is to be used to make the 
measurements. One measurement will be made within 6 inches of the vessel 
bottom, one near the vessel center and one near the vessel top. 
Measurements are to be made at each location until the reading is 
stabilized. All hydrocarbons measured are to be assumed to be vinyl 
chloride.
    (C) The production rate of polyvinyl chloride (Z) is to be 
determined by a method submitted to and approved by the Administrator.
    (ii) A calculation based on the number of evacuations, the vacuum 
involved, and the volume of gas in the reactor is hereby approved by the 
Administrator as an alternative method for determining reactor opening 
loss for postpolymerization reactors in the manufacture of bulk resins. 
Calculation methods based on techniques other than repeated evacuation 
of the

[[Page 50]]

reactor may be approved by the Administrator for determining reactor 
opening loss for postpolymerization reactors in the manufacture of bulk 
resins.
    (6) For a reactor that is used as a stripper, the emissions of vinyl 
chloride from reactor opening loss and all sources following the reactor 
used as a stripper for which an emission limit is prescribed in 
Sec. 61.64(f) are to be determined. The number of reactors for which the 
determination is to be made is to be specified by the Administrator for 
each individual plant at the time of the determination based on the 
plant's operation.
    (i) For each batch stripped in the reactor, the following 
measurements are to be made:
    (A) The concentration (ppm) of vinyl chloride in resin after 
stripping, measured according to paragraph (g)(3) of this section;
    (B) The reactor vacuum (mm Hg) at end of strip from plant 
instrument; and
    (C) The reactor temperature ( deg.C) at end of strip from plant 
instrument.
    (ii) For each batch stripped in the reactor, the following 
information is to be determined:
    (A) The vapor pressure (mm Hg) of water in the reactor at end of 
strip from the following table:

    (B) The partial pressure (mm Hg) of vinyl chloride in reactor at end 
of strip from the following equation:

PPVC= 760- RV- VPW

where:

PPVC=partial pressure of vinyl chloride, in mm Hg
760=atmospheric pressure at 0  deg.C, in mm Hg
RV=absolute value of reactor vacuum, in mm Hg
VPW=vapor pressure of water, in mm Hg

    (C) The reactor vapor space volume (m3) at end of strip 
from the following equation:
[GRAPHIC] [TIFF OMITTED] TC15NO91.048

where:

RVSV=reactor vapor space volume, in m\3\
RC=reactor capacity, in m\3\
WV=volume of water in reactor from recipe, in m\3\
PVCW=dry weight of polyvinyl chloride in reactor from recipe, in kg

[[Page 51]]

1,400=typical density of polyvinyl chloride, in kg/m\3\

    (iii) For each batch stripped in the reactor, the combined reactor 
opening loss and emissions from all sources following the reactor used 
as a stripper is to be determined using the following equation:
[GRAPHIC] [TIFF OMITTED] TC15NO91.049

where:

C=g vinyl chloride/kg polyvinyl chloride product
PPMVC=concentration of vinyl chloride in resin after stripping, in ppm
10-3=conversion factor for ppm
PPVC=partial pressure of vinyl chloride determined according to 
          paragraph (g)(6)(ii)(B) of this section, in mm Hg

          vinyl chloride
PVCW=dry weight of polyvinyl chloride in reactor from recipe, in kg
273=conversion factor for +C to +K
RT=reactor temperature, in +C

    (h)(1) Each piece of equipment within a process unit that can 
reasonably contain equipment in vinyl chloride service is presumed to be 
in vinyl chloride service unless an owner or operator demonstrates that 
the piece of equipment is not in vinyl chloride service. For a piece of 
equipment to be considered not in vinyl chloride service, it must be 
determined that the percent vinyl chloride content can be reasonably 
expected not to exceed 10 percent by weight for liquid streams or 
contained liquid volumes and 10 percent by volume for gas streams or 
contained gas volumes, which also includes gas volumes above liquid 
streams or contained liquid volumes. For purposes of determining the 
percent vinyl chloride content of the process fluid that is contained in 
or contacts equipment, procedures that conform to the methods described 
in ASTM Method D-2267 (incorporated by reference as specified in 
Sec. 61.18) shall be used.
    (2)(i) An owner or operator may use engineering judgment rather than 
the procedures in paragraph (h)(1) of this section to demonstrate that 
the percent vinyl chloride content does not exceed 10 percent by weight 
for liquid streams and 10 percent by volume for gas streams, provided 
that the engineering judgment demonstrates that the vinyl chloride 
content clearly does not exceed 10 percent. When an owner or operator 
and the Administrator do not agree on whether a piece of equipment is 
not in vinyl chloride service, however, the procedures in paragraph 
(h)(1) of this section shall be used to resolve the disagreement.
    (ii) If an owner or operator determines that a piece of equipment is 
in vinyl chloride service, the determination can be revised only after 
following the procedures in paragraph (h)(1) of this section.
    (3) Samples used in determining the percent vinyl chloride content 
shall be representative of the process fluid that is contained in or 
contacts the equipment.

Sec. 61.68  Emission monitoring.

    (a) A vinyl chloride monitoring system is to be used to monitor on a 
continuous basis the emissions from the sources for which emission 
limits are prescribed in Secs. 61.62 (a) and (b), 61.63(a), and 61.64 
(a)(1), (b), (c), and (d), and for any control system to which reactor 
emissions are required to be ducted in Sec. 61.64(a)(2) or to which 
fugitive emissions are required to be ducted in Sec. 61.65 (b)(1)(ii), 
and (b)(2), (b)(5), (b)(6) (ii), and (b)(9)(ii).
    (b) The vinyl chloride monitoring system(s) used to meet the 
requirement in paragraph (a) of this section is to be a device which 
obtains representative samples from one or more applicable emission 
points on a continuous

[[Page 52]]

sequential basis and analyzes the samples with gas chromatography or, if 
the owner or operator assumes that all hydrocarbons measured are vinyl 
chloride, with infrared spectrophotometry, flame ion detection, or an 
alternative method. The vinyl chloride monitoring system used to meet 
the requirements in Sec. 61.65(b)(8)(i) may be used to meet the 
requirements of this section.
    (c) A daily span check is to be conducted for each vinyl chloride 
monitoring system used. For all of the emission sources listed in 
paragraph (a) of this section, except the one for which an emission 
limit is prescribed in Sec. 61.62(b), the daily span check is to be 
conducted with a concentration of vinyl chloride equal to 10 ppm. For 
the emission source for which an emission limit is prescribed in 
Sec. 61.62(b), the daily span check is to be conducted with a 
concentration of vinyl chloride which is determined to be equivalent to 
the emission limit for that source based on the emission test required 
by Sec. 61.67. The calibration is to be done with either:
    (1) A calibration gas mixture prepared from the gases specified in 
sections 5.2.1 and 5.2.2 of Test Method 106 and in accordance with 
section 7.1 of Test Method 106, or
    (2) A calibration gas cylinder standard containing the appropriate 
concentration of vinyl chloride. The gas composition of the calibration 
gas cylinder standard is to have been certified by the manufacturer. The 
manufacturer must have recommended a maximum shelf life for each 
cylinder so that the concentration does not change greater than 
plus-minus5 percent from the certified value. The date of gas 
cylinder preparation, certified vinyl chloride concentration and 
recommended maximum shelf life must have been affixed to the cylinder 
before shipment from the manufacturer to the buyer. If a gas 
chromatograph is used as the vinyl chloride monitoring system, these gas 
mixtures may be directly used to prepare a chromatograph calibration 
curve as described in section 7.3 of Test Method 106. The requirements 
in sections 5.2.3.1 and 5.2.3.2 of Test Method 106 for certification of 
cylinder standards and for establishment and verification of calibration 
standards are to be followed.
    (d) When exhaust gas(es), having emission limits that are subject to 
the requirement of paragraph (a) of this section, are emitted to the 
atmosphere without passing through the control system and required vinyl 
chloride monitoring system, the vinyl chloride content of the emission 
shall be calculated (in units of each applicable emission limit) by best 
practical engineering judgment based on the discharge duration and known 
VC concentrations in the affected equipment as determined in accordance 
with Sec. 61.67(h) or other acceptable method.
    (e) For each 3-hour period, the vinyl chloride content of emissions 
subject to the requirements of paragraphs (a) and (d) of this section 
shall be averaged (weighted according to the proportion of time that 
emissions were continuously monitored and that emissions bypassed the 
continuous monitor) for purposes of reporting excess emissions under 
Sec. 61.70(c)(1).
    (f) For each vinyl chloride emission to the atmosphere determined in 
accordance with paragraph (e) of this section to be in excess of the 
applicable emission limits, the owner or operator shall record the 
identity of the source(s), the date, time, and duration of the excess 
emission, the cause of the excess emission, and the approximate total 
vinyl chloride loss during the excess emission, and the method used for 
determining the vinyl chloride loss. This information shall be retained 
and made available for inspection by the Administrator as required by 
Sec. 61.71(a).

emissions for which emission limits are prescribed in Sec. 61.65 
(b)(1)(i) and (b)(6)(i),
    (4) A statement that each piece of equipment is installed and that 
each piece of equipment and each procedure is being used.



Sec. 61.70  Reporting.

    (a)(1) The owner or operator of any source to which this subpart 
applies shall submit to the Administrator on March 15, June 15, 
September 15, and December 15 of each year a report in writing 
containing the information required by this section. The first report is 
to be submitted following the first full 3-month reporting period after 
the initial report is submitted.
    (2) In the case of an existing source, the approved reporting 
schedule shall be used. In addition, quarterly reports shall be 
submitted exactly 3 months following the current reporting dates.
    (b)(1) In the case of an existing source or a new source which has 
an initial startup date preceding the effective date, the first report 
is to be submitted within 180 days of the effective date, unless a 
waiver of compliance is granted under Sec. 61.11. If a waiver of 
compliance is granted, the first report is to be submitted on a date 
scheduled by the Administrator.
    (2) In the case of a new source which did not have an initial 
startup date preceding the effective date, the first report is to be 
submitted within 180 days of the initial startup date.
    (c) Unless otherwise specified, the owner or operator shall use the 
Test Methods in appendix B to this part to conduct emission tests as 
required by paragraphs (c)(2) and (c)(3) of this section, unless an 
alternative method has been approved by the Administrator. If the 
Administrator finds reasonable grounds to dispute the results obtained 
by an alternative method, he may require the use of a reference method. 
If the results of the reference and alternative methods do not agree, 
the results obtained by the reference method prevail, and the 
Administrator may notify the owner or operator that approval of the 
method previously considered to be alternative is withdrawn.
    (1) The owner or operator shall include in the report a record of 
the vinyl chloride content of emissions for each 3-hour period during 
which average emissions are in excess of the emission limits in 
Sec. 61.62 (a) or (b), Sec. 61.63 (a), or Sec. 61.64 (a)(1), (b), (c), 
or (d), or during which average emissions are in excess of the emission 
limits specified for any control system to which reactor emissions are 
required to be ducted in Sec. 61.64 (a)(2) or to which fugitive 
emissions are required to be ducted in Sec. 61.65 (b)(i)(ii), (b)(2), 
(b)(5), (b)(6)(ii), or (b)(9)(ii).The number of 3-hour periods for which 
average emissions were determined during the reporting period shall be 
reported. If emissions in excess of the emission limits are not 
detected, the report shall contain a statement that no excess emissions 
have been detected. The emissions are to be determined in accordance 
with Sec. 61.68(e).
    (2) In polyvinyl chloride plants for which a stripping operation is 
used to attain the emission level prescribed in Sec. 61.64(e), the owner 
or operator shall include in the report a record of the vinyl chloride 
content in the polyvinyl chloride resin.
    (i) If batch stripping is used, one representative sample of 
polyvinyl chloride resin is to be taken from each batch of each grade of 
resin immediately following the completion of the stripping operation, 
and identified by

[[Page 54]]

resin type and grade and the date and time the batch is completed. The 
corresponding quantity of material processed in each stripper batch is 
to be recorded and identified by resin type and grade and the date and 
time the batch is completed.
    (ii) If continuous stripping is used, one representative sample of 
polyvinyl chloride resin is to be taken for each grade of resin 
processed or at intervals of 8 hours for each grade of resin which is 
being processed, whichever is more frequent. The sample is to be taken 
as the resin flows out of the stripper and identified by resin type and 
grade and the date and time the sample was taken. The corresponding 
quantity of material processed by each stripper over the time period 
represented by the sample during the 8-hour period, is to be recorded 
and identified by resin type and grade and the date and time it 
represents.
    (iii) The vinyl chloride content in each sample is to be determined 
by Test Method 107 as prescribed in Sec. 61.67(g)(3).
    (iv) [Reserved]
    (v) The report to the Administrator by the owner or operator is to 
include a record of any 24-hour average resin vinyl chloride 
concentration, as determined in this paragraph, in excess of the limits 
prescribed in Sec. 61.64(e). The vinyl chloride content found in each 
sample required by paragraphs (c)(2)(i) and (c)(2)(ii) of this section 
shall be averaged separately for each type of resin, over each calendar 
day and weighted according to the quantity of each grade of resin 
processed by the stripper(s) that calendar day, according to the 
following equation:


where:
AT =24-hour average concentration of type T resin in ppm (dry 
          weight basis)
QT =Total production of type T resin over the 24-hour period, 
          in kg.
T=Type of resin.
MGi=Concentration of vinyl chloride in one sample of grade Gi 
          resin in ppm.
PGi=Production of grade Gi resin represented by the sample, 
          in kg.
Gi=Grade of resin: e.g., G1, G2, G3.
n=Total number of grades of resin produced during the 24-hour period.

    The number of 24-hour average concentrations for each resin type 
determined during the reporting period shall be reported. If no 24-hour 
average resin vinyl chloride concentrations in excess of the limits 
prescribed in Sec. 61.64(e) are measured, the report shall state that no 
excess resin vinyl chloride concentrations were measured.

    (vi) The owner or operator shall retain at the source and make 
available for inspection by the Administrator for a minimum of 3 years 
records of all data needed to furnish the information required by 
paragraph (c)(2)(v) of this section. The records are to contain the 
following information:
    (A) The vinyl chloride content found in all the samples required in 
paragraphs (c)(2)(i) and (c)(2)(ii) of this section, identified by the 
resin type and grade and the time and date of the sample, and
    (B) The corresponding quantity of polyvinyl chloride resin processed 
by the stripper(s), identified by the resin type and grade and the time 
and date it represents.
    (3) The owner or operator shall include in the report a record of 
any emissions from each reactor opening in excess of the emission limits 
prescribed in Sec. 61.64(a)(2). Emissions are to be determined in 
accordance with Sec. 61.67(g)(5), except that emissions for each reactor 
are to be determined. The number of reactor openings during the 
reporting period shall be reported. If emissions in excess of the 
emission limits are not detected, the report

[[Page 55]]

shall include a statement that excess emissions have not been detected.
    (4) In polyvinyl chloride plants for which stripping in the reactor 
is used to attain the emission level prescribed in Sec. 61.64(f), the 
owner or operator shall include in the report a record of the vinyl 
chloride emissions from reactor opening loss and all sources following 
the reactor used as a stripper.
    (i) One representative sample of polyvinyl chloride resin is to be 
taken from each batch of each grade of resin immediately following the 
completion of the stripping operation, and identified by resin type and 
grade and the date and time the batch is completed. The corresponding 
quantity of material processed in each stripper batch is to be recorded 
and identified by resin type and grade and the date and time the batch 
is completed.
    (ii) The vinyl chloride content in each sample is to be determined 
by Test Method 107 as prescribed in Sec. 61.67(g)(3).
    (iii) The combined emissions from reactor opening loss and all 
sources following the reactor used as a stripper are to be determined 
for each batch stripped in a reactor according to the procedure 
prescribed in Sec. 61.67(g)(6).
    (iv) The report to the Administrator by the owner or operator is to 
include a record of any 24-hour average combined reactor opening loss 
and emissions from all sources following the reactor used as a stripper 
as determined in this paragraph, in excess of the limits prescribed in 
Sec. 61.64(f). The combined reactor opening loss and emissions from all 
sources following the reactor used as a stripper associated with each 
batch are to be averaged separately for each type of resin, over each 
calendar day and weighted according to the quantity of each grade of 
resin stripped in reactors that calendar day as follows:
    For each type of resin (suspension, dispersion, latex, bulk, other), 
the following calculation is to be performed:


where:
AT =24-hour average combined reactor opening loss and 
          emissions from all sources following the reactor used as a 
          stripper, in g vinyl chloride/kg product (dry weight basis).
QT=Total production of resin in batches for which stripping 
          is completed during the 24-hour period, in kg.
T=Type of resin.
CGi=Average combined reactor opening loss and emissions from 
          all sources following the reactor used as a stripper of all 
          batches of grade Gi resin for which stripping is 
          completed during the 24-hour period, in g vinyl chloride/kg 
          product (dry weight basis) (determined according to procedure 
          prescribed in Sec. 61.67(g)(6)).
PGi=Production of grade Gi resin in the batches 
          for which C is determined, in kg.
Gi=Grade of resin e.g., G1, G2, and 
          G3.
n=Total number of grades of resin in batches for which stripping is 
          completed during the 24-hour period.

    The number of 24-hour average emissions determined during the 
reporting period shall be reported. If no 24-hour average combined 
reactor opening loss and emissions from all sources following the 
reactor used a stripper in excess of the limits prescribed in 
Sec. 61.64(f) are determined, the report shall state that no excess 
vinyl chloride emissions were determined.

 Subpart H--National Emission Standards for Emissions of Radionuclides 
          Other Than Radon From Department of Energy Facilities

    Source: 54 FR 51695, Dec. 15, 1989, unless otherwise noted.



Sec. 61.90  Designation of facilities.

    The provisions of this subpart apply to operations at any facility 
owned or operated by the Department of Energy that emits any 
radionuclide other than radon-222 and radon-220 into the air, except 
that this subpart does not apply to disposal at facilities subject to 40 
CFR part 191, subpart B or 40 CFR part 192.



Sec. 61.91  Definitions.

    As used in this subpart, all terms not defined here have the meaning 
given them in the Clean Air Act or 40 CFR part 61, subpart A. The 
following terms shall have the following specific meanings:
    (a) Effective dose equivalent means the sum of the products of 
absorbed dose and appropriate factors to account for differences in 
biological effectiveness due to the quality of radiation and its 
distribution in the body of reference man. The unit of the effective 
dose equivalent is the rem. For purposes of this subpart, doses caused 
by radon-222 and its respective decay products formed after the radon is 
released from the facility are not included. The method for calculating 
effective dose equivalent and the definition of reference man are 
outlined in the International Commission on Radiological Protection's 
Publication No. 26.
    (b) Facility means all buildings, structures and operations on one 
contiguous site.
    (c) Radionuclide means a type of atom which spontaneously undergoes 
radioactive decay.
    (d) Residence means any home, house, apartment building, or other 
place of dwelling which is occupied during any portion of the relevant 
year.



Sec. 61.92  Standard.

    Emissions of radionuclides to the ambient air from Department of 
Energy facilities shall not exceed those amounts that would cause any 
member of the public to receive in any year an effective dose equivalent 
of 10 mrem/yr.



Sec. 61.93  Emission monitoring and test procedures.

    (a) To determine compliance with the standard, radionuclide 
emissions shall be determined and effective dose equivalent values to 
members of the public calculated using EPA approved sampling procedures, 
computer models CAP-88 or AIRDOS-PC, or other procedures for which EPA 
has granted prior approval. DOE facilities for which the maximally 
exposed individual lives within 3 kilometers of all sources of emissions 
in the facility, may use EPA's COMPLY model and associated procedures 
for determining dose for purposes of compliance.
    (b) Radionuclide emission rates from point sources (stacks or vents) 
shall be measured in accordance with the following requirements or other 
procedures for which EPA has granted prior approval:

[[Page 57]]

    (1) Effluent flow rate measurements shall be made using the 
following methods:
    (i) Reference Method 2 of appendix A to part 60 shall be used to 
determine velocity and volumetric flow rates for stacks and large vents.
    (ii) Reference Method 2A of appendix A to part 60 shall be used to 
measure flow rates through pipes and small vents.
    (iii) The frequency of the flow rate measurements shall depend upon 
the variability of the effluent flow rate. For variable flow rates, 
continuous or frequent flow rate measurements shall be made. For 
relatively constant flow rates only periodic measurements are necessary.
    (2) Radionuclides shall be directly monitored or extracted, 
collected and measured using the following methods:
    (i) Reference Method 1 of appendix A part 60 shall be used to select 
monitoring or sampling sites.
    (ii) The effluent stream shall be directly monitored continuously 
with an in-line detector or representative samples of the effluent 
stream shall be withdrawn continuously from the sampling site following 
the guidance presented in ANSIN13.1-1969 ``Guide to Sampling Airborne 
Radioactive Materials in Nuclear Facilities'' (including the guidance 
presented in appendix A of ANSIN13.1) (incorporated by reference--see 
Sec. 61.18). The requirements for continuous sampling are applicable to 
batch processes when the unit is in operation. Periodic sampling (grab 
samples) may be used only with EPA's prior approval. Such approval may 
be granted in cases where continuous sampling is not practical and 
radionuclide emission rates are relatively constant. In such cases, grab 
samples shall be collected with sufficient frequency so as to provide a 
representative sample of the emissions.
    (iii) Radionuclides shall be collected and measured using procedures 
based on the principles of measurement described in appendix B, Method 
114. Use of methods based on principles of measurement different from 
those described in appendix B, Method 114 must have prior approval from 
the Administrator. EPA reserves the right to approve measurement 
procedures.
    (iv) A quality assurance program shall be conducted that meets the 
performance requirements described in appendix B, Method 114.
    (3) When it is impractical to measure the effluent flow rate at an 
existing source in accordance with the requirements of paragraph (b)(1) 
of this section or to monitor or sample an effluent stream at an 
existing source in accordance with the site selection and sample 
extraction requirements of paragraph (b)(2) of this section, the 
facility owner or operator may use alternative effluent flow rate 
measurement procedures or site selection and sample extraction 
procedures provided that:
    (i) It can be shown that the requirements of paragraph (b) (1) or 
(2) of this section are impractical for the effluent stream.
    (ii) The alternative procedure will not significantly underestimate 
the emissions.
    (iii) The alternative procedure is fully documented.
    (iv) The owner or operator has received prior approval from EPA.
    (4)(i) Radionuclide emission measurements in conformance with the 
requirements of paragraph (b) of this section shall be made at all 
release points which have a potential to discharge radionuclides into 
the air in quantities which could cause an effective dose equivalent in 
excess of 1% of the standard. All radionuclides which could contribute 
greater than 10% of the potential effective dose equivalent for a 
release point shall be measured. With prior EPA approval, DOE may 
determine these emissions through alternative procedures. For other 
release points which have a potential to release radionuclides into the 
air, periodic confirmatory measurements shall be made to verify the low 
emissions.
    (ii) To determine whether a release point is subject to the emission 
measurement requirements of paragraph (b) of this section, it is 
necessary to evaluate the potential for radionuclide emissions for that 
release point. In evaluating the potential of a release point to 
discharge radionuclides into the air for the purposes of this section, 
the estimated radionuclide release rates shall

[[Page 58]]

be based on the discharge of the effluent stream that would result if 
all pollution control equipment did not exist, but the facilities 
operations were otherwise normal.
    (5) Environmental measurements of radionuclide air concentrations at 
critical receptor locations may be used as an alternative to air 
dispersion calculations in demonstrating compliance with the standard if 
the owner or operator meets the following criteria:
    (i) The air at the point of measurement shall be continuously 
sampled for collection of radionuclides.
    (ii) Those radionuclides released from the facility, which are the 
major contributors to the effective dose equivalent must be collected 
and measured as part of the environmental measurement program.
    (iii) Radionuclide concentrations which would cause an effective 
dose equivalent of 10% of the standard shall be readily detectable and 
distinguishable from background.
    (iv) Net measured radionuclide concentrations shall be compared to 
the concentration levels in Table 2 of appendix E to determine 
compliance with the standard. In the case of multiple radionuclides 
being released from a facility, compliance shall be demonstrated if the 
value for all radionuclides is less than the concentration level in 
Table 2, and the sum of the fractions that result when each measured 
concentration value is divided by the value in Table 2 for each 
radionuclide is less than 1.
    (v) A quality assurance program shall be conducted that meets the 
performance requirements described in appendix B, Method 114.
    (vi) Use of environmental measurements to demonstrate compliance 
with the standard is subject to prior approval of EPA. Applications for 
approval shall include a detailed description of the sampling and 
analytical methodology and show how the above criteria will be met.



Sec. 61.94  Compliance and reporting.

    (a) Compliance with this standard shall be determined by calculating 
the highest effective dose equivalent to any member of the public at any 
offsite point where there is a residence, school, business or office. 
The owners or operators of each facility shall submit an annual report 
to both EPA headquarters and the appropriate regional office by June 30 
which includes the results of the monitoring as recorded in DOE's 
Effluent Information System and the dose calculations required by 
Sec. 61.93(a) for the previous calendar year.
    (b) In addition to the requirements of paragraph (a) of this 
section, an annual report shall include the following information:
    (1) The name and location of the facility.
    (2) A list of the radioactive materials used at the facility.
    (3) A description of the handling and processing that the 
radioactive materials undergo at the facility.
    (4) A list of the stacks or vents or other points where radioactive 
materials are released to the atmosphere.
    (5) A description of the effluent controls that are used on each 
stack, vent, or other release point and an estimate of the efficiency of 
each control device.
    (6) Distances from the points of release to the nearest residence, 
school, business or office and the nearest farms producing vegetables, 
milk, and meat.
    (7) The values used for all other user-supplied input parameters for 
the computer models (e.g., meteorological data) and the source of these 
data.
    (8) A brief description of all construction and modifications which 
were completed in the calendar year for which the report is prepared, 
but for which the requirement to apply for approval to construct or 
modify was waived under Sec. 61.96 and associated documentation 
developed by DOE to support the waiver. EPA reserves the right to 
require that DOE send to EPA all the information that normally would be 
required in an application to construct or modify, following receipt of 
the description and supporting documentation.
    (9) Each report shall be signed and dated by a corporate officer or 
public official in charge of the facility and contain the following 
declaration immediately above the signature line: ``I certify under 
penalty of law that I have personally examined and am familiar with the 
information submitted herein

[[Page 59]]

and 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. See, 18 U.S.C. 1001.''
    (c) If the facility is not in compliance with the emission limits of 
Sec. 61.92 in the calendar year covered by the report, then the facility 
must commence reporting to the Administrator on a monthly basis the 
information listed in paragraph (b) of this section, for the preceding 
month. These reports will start the month immediately following the 
submittal of the annual report for the year in noncompliance and will be 
due 30 days following the end of each month. This increased level of 
reporting will continue until the Administrator has determined that the 
monthly reports are no longer necessary. In addition to all the 
information required in paragraph (b) of this section, monthly reports 
shall also include the following information:
    (1) All controls or other changes in operation of the facility that 
will be or are being installed to bring the facility into compliance.
    (2) If the facility is under a judicial or administrative 
enforcement decree, the report will describe the facilities performance 
under the terms of the decree.
    (d) In those instances where the information requested is 
classified, such information will be made available to EPA separate from 
the report and will be handled and controlled according to applicable 
security and classification regulations and requirements.



Sec. 61.95  Recordkeeping requirements.

    All facilities must maintain records documenting the source of input 
parameters including the results of all measurements upon which they are 
based, the calculations and/or analytical methods used to derive values 
for input parameters, and the procedure used to determine effective dose 
equivalent. This documentation should be sufficient to allow an 
independent auditor to verify the accuracy of the determination made 
concerning the facility's compliance with the standard. These records 
must be kept at the site of the facility for at least five years and, 
upon request, be made available for inspection by the Administrator, or 
his authorized representative.



Sec. 61.96  Applications to construct or modify.

    (a) In addition to any activity that is defined as construction 
under 40 CFR part 61, subpart A, any fabrication, erection or 
installation of a new building or structure within a facility that emits 
radionuclides is also defined as new construction for purposes of 40 CFR 
part 61, subpart A.
    (b) An application for approval under Sec. 61.07 or notification of 
startup under Sec. 61.09 does not need to be filed for any new 
construction of or modification within an existing facility if the 
effective dose equivalent, caused by all emissions from the new 
construction or modification, is less than 1% of the standard prescribed 
in Sec. 61.92. For purposes of this paragraph the effective dose 
equivalent shall be calculated using the source term derived using 
appendix D as input to the dispersion and other computer models 
described in Sec. 61.93. DOE may, with prior approval from EPA, use 
another procedure for estimating the source term for use in this 
paragraph. A facility is eligible for this exemption only if, based on 
its last annual report, the facility is in compliance with this subpart.
    (c) Conditions to approvals granted under Sec. 61.08 will not 
contain requirements for post approval reporting on operating conditions 
beyond those specified in Sec. 61.94.



Sec. 61.97  Exemption from the reporting and testing requirements of 40 CFR 61.10.

    All facilities designated under this subpart are exempt from the 
reporting requirements of 40 CFR 61.10.

measure flow rates through pipes and small vents.
    (iii) The frequency of the flow rate measurements shall depend upon 
the variability of the effluent flow rate. For variable flow rates, 
continuous or frequent flow rate measurements shall be made. For 
relatively constant flow rates only periodic measurements are necessary.
    (2) Radionuclides shall be directly monitored or extracted, 
collected, and measured using the following methods:
    (i) Reference Method 1 of appendix A part 60 shall be used to select 
monitoring or sampling sites.
    (ii) The effluent stream shall be directly monitored continuously 
using an in-line detector or representative samples of the effluent 
stream shall be withdrawn continuously from the sampling site following 
the guidance presented in ANSIN13.1-1969 ``Guide to Sampling Airborne 
Radioactive Materials in Nuclear Facilities'' (including the guidance 
presented in appendix A of ANSIN13.1) (incorporated by reference--see 
Sec. 61.18). The requirements for continuous sampling are applicable to 
batch processes when the unit is in operation. Periodic sampling (grab 
samples) may be used only with EPA's prior approval. Such approval may 
be granted in cases where continuous sampling is not practical and 
radionuclide emission rates are relatively constant. In such cases, grab 
samples

[[Page 63]]

shall be collected with sufficient frequency so as to provide a 
representative sample of the emissions.
    (iii) Radionuclides shall be collected and measured using procedures 
based on the principles of measurement described in appendix B, Method 
114. Use of methods based on principles of measurement different from 
those described in appendix B, Method 114 must have prior approval from 
the Administrator. EPA reserves the right to approve alternative 
measurement procedures in whole or in part.
    (iv) A quality assurance program shall be conducted that meets the 
performance requirements described in appendix B, method 114.
    (3) When it is impractical to measure the effluent flow rate at an 
existing source in accordance with the requirements of paragraph (b)(1) 
of this section or to monitor or sample an effluent stream at an 
existing source in accordance with the site selection and sample 
extraction requirements of paragraph (b)(2) of this section, the 
facility owner or operator may use alternative effluent flow rate 
measurement procedures or site selection and sample extraction 
procedures provided that:
    (i) It can be shown that the requirements of paragraphs (b) (1) and 
(2) of this section are impractical for the effluent stream.
    (ii) The alternative procedure will not significantly underestimate 
the emissions.
    (iii) The alternative procedure is fully documented.
    (iv) The owner or operator has received prior approval from EPA.
    (4)(i) Radionuclide emission measurements in conformance with the 
requirements of paragraph (b) of this section shall be made at all 
release points which have a potential to discharge radionuclides into 
the air in quantities which could cause an effective dose equivalent in 
excess of 1% of the standard. All radionuclides which could contribute 
greater than 10% of the potential effective dose equivalent for a 
release point shall be measured. For other release points which have a 
potential to release radionuclides into the air, periodic confirmatory 
measurements should be made to verify the low emissions.
    (ii) To determine whether a release point is subject to the emission 
measurement requirements of paragraph (b) of this section, it is 
necessary to evaluate the potential for radionuclide emissions for that 
release point. In evaluating the potential of a release point to 
discharge radionuclides into the air, the estimated radionuclide release 
rates shall be based on the discharge of the uncontrolled effluent 
stream into the air.
    (5) Environmental measurements of radionuclide air concentrations at 
critical receptor locations may be used as an alternative to air 
dispersion calculations in demonstrating compliance with the standards 
if the owner or operator meets the following criteria:
    (i) The air at the point of measurement shall be continuously 
sampled for collection of radionuclides.
    (ii) Those radionuclides released from the facility, which are the 
major contributors to the effective dose equivalent must be collected 
and measured as part of the environmental measurements program.
    (iii) Radionuclide concentrations which would cause an effective 
dose equivalent greater than or equal to 10% of the standard shall be 
readily detectable and distinguishable from background.
    (iv) Net measured radionuclide concentrations shall be compared to 
the concentration levels in table 2 of appendix E to determine 
compliance with the standard. In the case of multiple radionuclides 
being released from a facility, compliance shall be demonstrated if the 
value for all radionuclides is less than the concentration level in 
table 2 and the sum of the fractions that result when each measured 
concentration value is divided by the value in table 2 for each 
radionuclide is less than 1.
    (v) A quality assurance program shall be conducted that meets the 
performance requirements described in appendix B, method 114.
    (vi) Use of environmental measurements to demonstrate compliance 
with the standard is subject to prior approval of EPA. Applications for 
approval shall include a detailed description of the sampling and 
analytical

methodology and show how the above criteria will be met.
    (c) The following facilities may use either the methodologies and 
quality assurance programs described in paragraph (b) of this section or 
may use the following:
    (1) [Reserved]
    (2) Uranium mills may determine their emissions in conformance with 
the Nuclear Regulatory Commission's Regulatory Guide 4.14 dated April 
1980. In addition, they may conduct a quality assurance program as 
described in the Nuclear Regulatory Commission's Regulatory Guide 4.15 
dated February 1979.

 Subpart K--National Emission Standards for Radionuclide Emissions From 
                       Elemental Phosphorus Plants

    Source: 54 FR 51699, Dec. 15, 1989, unless otherwise noted.



Sec. 61.120  Applicability.

    The provisions of this subpart are applicable to owners or operators 
of calciners and nodulizing kilns at elemental phosphorus plants.



Sec. 61.121  Definitions.

    (a) Elemental phosphorus plant or plant means any facility that 
processes phosphate rock to produce elemental phosphorus. A plant 
includes all buildings, structures, operations, calciners and nodulizing 
kilns on one contiguous site.
    (b) Calciner or Nodulizing kiln means a unit in which phosphate rock 
is heated to high temperatures to remove organic material and/or to 
convert it to a nodular form. For the purpose of this subpart, calciners 
and nodulizing kilns are considered to be similar units.



Sec. 61.122  Emission standard.

    Emissions of polonium-210 to the ambient air from all calciners and 
nodulizing kilns at an elemental phosphorus plant shall not exceed a 
total of 2 curies a year; except that compliance with this standard may 
be conclusively shown if the elemental phosphorus plant:
    (a) Installs a Hydro-Sonic Tandem Nozzle Fixed Throat 
Free-Jet Scrubber System including four scrubber units,
    (b) All four scrubber units are operated continuously with a minimum 
average over any 6-hour period of 40 inches (water column) of pressure 
drop across each scrubber during calcining of phosphate shale,
    (c) The system is used to scrub emissions from all calciners and/or 
nodulizing kilns at the plant, and
    (d) Total emissions of polonium-210 from the plant do not exceed 4.5 
curies per year.

Alternative operating conditions, which can be shown to achieve an 
overall removal efficiency for emissions of polonium-210 which is equal 
to or greater than the efficiency which would be achieved under the 
operating conditions described in paragraphs (a), (b), and (c) of this 
section, may be used with prior approval of the Administrator. A 
facility shall apply for such approval in writing, and the Administrator 
shall act upon the request within 30 days after receipt of a complete 
and technically sufficient application.

[56 FR 65943, Dec. 19, 1991]



Sec. 61.123  Emission testing.

    (a) Each owner or operator of an elemental phosphorus plant shall 
test emissions from the plant within 90 days of the effective date of 
this standard and annually thereafter. The Administrator may temporarily 
or permanently waive the annual testing requirement or increase the 
frequency of testing, if the Administrator determines that more testing 
is required.
    (b) The Administrator shall be notified at least 30 days prior to an 
emission test so that EPA may, at its option, observe the test.
    (c) An emission test shall be conducted at each operational calciner 
or nodulizing kiln. If emissions from a calciner or nodulizing kiln are 
discharged through more than one stack, then an emission test shall be 
conducted at each stack and the total emission rate from the calciner or 
kiln shall be the sum of the emission rates from each of the stacks.
    (d) Each emission test shall consist of three sampling runs that 
meet the requirements of Sec. 61.125. The phosphate rock processing rate 
during each run shall be recorded. An emission rate in curies per metric 
ton of phosphate rock processed shall be calculated for each run. The 
average of all three runs shall apply in computing the emission rate for 
the test. The annual polonium-210 emission rate from a calciner or 
nodulizing kiln shall be determined by multiplying the measured 
polonium-210 emission rate in curies per metric ton of phosphate rock 
processed by the annual phosphate rock processing rate in metric tons. 
In determining the annual phosphate rock processing rate, the values 
used for operating hours and operating capacity shall be values that 
will maximize the expected processing rate. For determining compliance 
with

[[Page 66]]

the emission standard of Sec. 61.122, the total annual emission rate is 
the sum of the annual emission rates for all operating calciners and 
nodulizing kilns.
    (e) If the owner or operator changes his operation in such a way as 
to increase his emissions of polonium-210, such as changing the type of 
rock processed, the temperature of the calciners or kilns, or increasing 
the annual phosphate rock processing rate, then a new emission test, 
meeting the requirements of this section, shall be conducted within 45 
days under these conditions.
    (f) Each owner or operator of an elemental phosphorus plant shall 
furnish the Administrator with a written report of the results of the 
emission test within 60 days of conducting the test. The report must 
provide the following information:
    (1) The name and location of the facility.
    (2) The name of the person responsible for the operation of the 
facility and the name of the person preparing the report (if different).
    (3) A description of the effluent controls that are used on each 
stack, vent, or other release point and an estimate of the efficiency of 
each device.
    (4) The results of the testing, including the results of each 
sampling run completed.
    (5) The values used in calculating the emissions and the source of 
these data.
    (6) Each report shall be signed and dated by a corporate officer in 
charge of the facility and contain the following declaration immediately 
above the signature line: ``I certify under penalty of law that I have 
personally examined and am familiar with the information submitted 
herein and 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. See, 18 U.S.C. 1001.''



Sec. 61.124  Recordkeeping requirements.

    The owner or operator of any plant must maintain records documenting 
the source of input parameters including the results of all measurements 
upon which they are based, the calculations and/or analytical methods 
used to derive values for input parameters, and the procedure used in 
emission testing. This documentation should be sufficient to allow an 
independent auditor to verify the accuracy of the results of the 
emission testing. These records must be kept at the site of the plant 
for at least five years and, upon request, be made available for 
inspection by the Administrator, or his authorized representative.



Sec. 61.125  Test methods and procedures.

    (a) Each owner or operator of a source required to test emissions 
under Sec. 61.123, unless an equivalent or alternate method has been 
approved by the Administrator, shall use the following test methods:
    (1) Test Method 1 of appendix A to 40 CFR part 60 shall be used to 
determine sample and velocity traverses;
    (2) Test Method 2 of appendix A to 40 CFR part 60 shall be used to 
determine velocity and volumetric flow rate;

collect particulate matter containing the polonium-210; and
    (5) Test Method 111 of appendix B to 40 CFR part 61 shall be used to 
determine the polonium-210 emissions.



Sec. 61.126  Monitoring of operations.

    (a) The owner or operator of any source subject to this subpart 
using a wet-scrubbing emission control device shall install, calibrate, 
maintain, and operate a monitoring device for the continuous measurement 
and recording of the pressure drop of the gas stream across each 
scrubber. The monitoring device must be certified by the manufacturer to 
be accurate within 250 pascal (1 inch of water). 
The owner or operator of any source subject to this subpart using a wet-
scrubbing emission control device shall also install, calibrate, 
maintain, and operate a monitoring device for the continuous measurement 
and recording of the scrubber

Sec. 61.132  Standard: Process vessels, storage tanks, and tar-intercepting sumps.

    (a)(1) Each owner or operator of a furnace or a foundry coke 
byproduct recovery plant shall enclose and seal all openings on each 
process vessel, tar storage tank, and tar-intercepting sump.
    (2) The owner or operator shall duct gases from each process vessel, 
tar storage tank, and tar-intercepting sump to the gas collection 
system, gas distribution system, or other enclosed point in the by-
product recovery process where the benzene in the gas will be recovered 
or destroyed. This control system shall be designed and operated for no 
detectable emissions, as indicated by an instrument reading of less than 
500 ppm above background and visual inspections, as determined by the 
methods specified in Sec. 61.245(c). This system can be designed as a 
closed, positive pressure, gas blanketing system.
    (i) Except, the owner or operator may elect to install, operate, and 
maintain a pressure relief device, vacuum relief device, an access 
hatch, and a sampling port on each process vessel, tar storage tank, and 
tar-intercepting sump. Each access hatch and sampling port must be 
equipped with a gasket and a cover, seal, or lid that must be kept in a 
closed position at all times, unless in actual use.
    (ii) The owner or operator may elect to leave open to the atmosphere 
the portion of the liquid surface in each tar decanter necessary to 
permit operation of a sludge conveyor. If the owner or operator elects 
to maintain an opening on part of the liquid surface of the tar 
decanter, the owner or operator shall install, operate, and maintain a 
water leg seal on the tar decanter roof near the sludge discharge chute 
to ensure enclosure of the major portion of liquid surface not necessary 
for the operation of the sludge conveyor.
    (b) Following the installation of any control equipment used to meet 
the requirements of paragraph (a) of this section, the owner or operator 
shall monitor the connections and seals on each control system to 
determine if it is operating with no detectable emissions, using 
Reference Method 21 (40 CFR part 60, appendix A) and procedures 
specified in Sec. 61.245(c), and shall visually inspect each source 
(including sealing materials) and the ductwork of the control system for 
evidence of visible defects such as gaps or tears. This monitoring and 
inspection shall be conducted on a semiannual basis and at any other 
time after the control system is repressurized with blanketing gas 
following removal of the cover or opening of the access hatch.
    (1) If an instrument reading indicates an organic chemical 
concentration more than 500 ppm above a background concentration, as 
measured by Reference Method 21, a leak is detected.
    (2) If visible defects such as gaps in sealing materials are 
observed during a visual inspection, a leak is detected.
    (3) When a leak is detected, it shall be repaired as soon as 
practicable, but not later than 15 calendar days after it is detected.
    (4) A first attempt at repair of any leak or visible defect shall be 
made no

[[Page 70]]

later than 5 calendar days after each leak is detected.
    (c) Following the installation of any control system used to meet

Sec. 61.139  Provisions for alternative means for process vessels, storage tanks, and tar-intercepting sumps.

    (a) As an alternative means of emission limitation for a source 
subject to Sec. 61.132(a)(2) or Sec. 61.132(d), the owner or operator 
may route gases from the source through a closed vent system to a carbon 
adsorber or vapor incinerator that is at least 98 percent efficient at 
removing benzene from the gas stream.
    (1) The provisions of Sec. 61.132(a)(1) and Sec. 61.132(a) (2)(i) 
and (ii) shall apply to the source.
    (2) The seals on the source and closed vent system shall be designed 
and operated for no detectable emissions, as indicated by an instrument 
reading of less than 500 ppm above background and visual inspections, as 
determined by the methods specified in Sec. 61.245(c).
    (3) The provisions of Sec. 61.132(b) shall apply to the seals and 
closed vent system.
    (b) For each carbon adsorber, the owner or operator shall adhere to 
the following practices:
    (1) Benzene captured by each carbon adsorber shall be recycled or 
destroyed in a manner that prevents benzene from being emitted to the 
atmosphere.
    (2) Carbon removed from each carbon adsorber shall be regenerated or 
destroyed in a manner that prevents benzene from being emitted to the 
atmosphere.
    (3) For each regenerative carbon adsorber, the owner or operator 
shall

[[Page 74]]

initiate regeneration of the spent carbon bed and vent the emissions 
from the source to a regenerated carbon bed no later than when the 
benzene concentration or organic vapor concentration level in the 
adsorber outlet vent reaches the maximum concentration point, as 
determined in Sec. 61.139(h).
    (4) For each non-regenerative carbon adsorber, the owner or operator 
shall replace the carbon at the scheduled replacement time, or as soon 
as practicable (but not later than 16 hours) after an exceedance of the 
maximum concentration point is detected, whichever is sooner.
    (i) For each non-regenerative carbon adsorber, the scheduled 
replacement time means the day that is estimated to be 90 percent of the 
demonstrated bed life, as defined in Sec. 61.139(h)(5).
    (ii) For each non-regenerative carbon adsorber, an exceedance of the 
maximum concentration point shall mean any concentration greater than or 
equal to the maximum concentration point as determined in 
Sec. 61.139(h).
    (c) Compliance with the provisions of this section shall be 
determined as follows:

    (1) For each carbon adsorber and vapor incinerator, the owner or 
operator shall demonstrate compliance with the efficiency limit by a 
compliance test as specified in Sec. 61.13 and Sec. 61.139(g). If a 
waiver of compliance has been granted under Sec. 61.11, the deadline for 
conducting the initial compliance test shall be incorporated into the 
terms of the waiver. The benzene removal efficiency rate for each carbon 
adsorber and vapor incinerator shall be calculated as in the following 
equation:


Where:
E=percent removal of benzene.
Caj=concentration of benzene in vents after the control 
          device, parts per million (ppm).
Cbi=concentration of benzene in vents before the control 
          device, ppm.
Qaj=volumetric flow rate in vents after the control device, 
          standard cubic meters/minute (scm/min).
Qbi=volumetric flow rate in vents before the control device, 
          scm/min.
m=number of vents after the control device.
n=number of vents after the control device.

    (2) Compliance with all other provisions in this section shall be 
determined by inspections or the review of records and reports.
    (d) For each regenerative carbon adsorber, the owner or operator 
shall install and operate a monitoring device that continuously 
indicates and records either the concentration of benzene or the 
concentration level of organic compounds in the outlet vent of the 
carbon adsorber. The monitoring device shall be installed, calibrated, 
maintained and operated in accordance with the manufacturer's 
specifications.
    (1) Measurement of benzene concentration shall be made according to 
Sec. 61.139(g)(2).
    (2) All measurements of organic compound concentration levels shall 
be reasonable indicators of benzene concentration.
    (i) The monitoring device for measuring organic compound 
concentration levels shall be based on one of the following detection 
principles: Infrared absorption, flame ionization, catalytic oxidation, 
photoionization, or thermal conductivity.
    (ii) The monitoring device shall meet the requirements of part 60, 
appendix A, method 21, sections 2, 3, 4.1, 4.2, and 4.4. For the purpose 
of the application of method 21 to this section, the words ``leak 
definition'' shall be the maximum concentration point, which would be 
estimated until it is established under Sec. 61.139(h). The calibration 
gas shall either be benzene or methane and shall be at a concentration 
associated with 125 percent of the expected organic compound 
concentration level for the carbon adsorber outlet vent.
    (e) For each non-regenerative carbon adsorber, the owner or operator 
shall monitor either the concentration of benzene or the concentration 
level of organic compounds at the outlet vent of the adsorber. The 
monitoring device shall be calibrated, operated and maintained in 
accordance with the manufacturer's specifications.
    (1) Measurements of benzene concentration shall be made according to 
Sec. 61.139(g)(2). The measurement shall be

[[Page 75]]

conducted over at least one 5-minute interval during which flow into the 
carbon adsorber is expected to occur.
    (2) All measurements of organic compound concentration levels shall 
be reasonable indicators of benzene concentration.
    (i) The monitoring device for measuring organic compound 
concentration levels shall meet the requirements of paragraphs 
Sec. 61.139(d)(2) (i) and (ii).
    (ii) The probe inlet of the monitoring device shall be placed at 
approximately the center of the carbon adsorber outlet vent. The probe 
shall be held there for at least 5 minutes during which flow into the 
carbon adsorber is expected to occur. The maximum reading during that 
period shall be used as the measurement.
    (3) Monitoring shall be performed at least once within the first 7 
days after replacement of the carbon bed occurs, and monthly thereafter 
until 10 days before the scheduled replacement time, at which point 
monitoring shall be done daily, except as specified in paragraphs (e)(4) 
and (e)(5) of this section.
    (4) If an owner or operator detects an exceedance of the maximum 
concentration point during the monthly monitoring or on the first day of 
daily monitoring as prescribed in paragraph (e)(3) of this section, 
then, after replacing the bed, the owner or operator shall begin the 
daily monitoring of the replacement carbon bed on the day after the last 
scheduled monthly monitoring before the exceedance was detected, or 10 
days before the exceedance was detected, whichever is longer.
    (5) If an owner or operator detects an exceedance of the maximum 
concentration point during the daily monitoring as prescribed in 
paragraph (e)(3) of this section, except on the first day, then, after 
replacing the bed, the owner or operator shall begin the daily 
monitoring of the replacement carbon bed 10 days before the exceedance 
was detected.
    (6) If the owner or operator is monitoring on the schedule required 
in paragraph (e)(4) or paragraph (e)(5) of this section, and the 
scheduled replacement time is reached without exceeding the maximum 
concentration point, the owner or operator may return to the monitoring 
schedule in paragraph (e)(3) of this section for subsequent carbon beds.
    Note: This note provides an example of the monitoring schedules in 
paragraphs (e)(3), (e)(4) and (e)(5) of this section. Assume that the 
scheduled replacement time for a non-regenerative carbon adsorber is the 
105th day after installation. According to the monitoring schedule in 
paragraph (e)(3) of this section, initial monitoring would be done 
within 7 days after installation, monthly monitoring would be done on 
the 30th, 60th and 90th days, and daily monitoring would begin on the 
95th day after installation. Now assume that an exceedance of the 
maximum concentration point is detected on the 90th day after 
installation. On the replacement carbon bed, the owner or operator would 
begin daily monitoring on the 61st day after installation (i.e., the day 
after the last scheduled monthly monitoring before the exceedance was 
detected), according to the requirements in paragraph (e)(4) of this 
section. If, instead, the exceedance were detected on the first bed on 
the 95th day, the daily monitoring of the replacement bed would begin on 
the 85th day after installation (i.e., 10 days before the point in the 
cycle where the exceedance was detected); this is a second example of 
the requirements in paragraph (e)(4) of this section. Finally, assume 
that an exceedance of the maximum concentration point is detected on the 
100th day after the first carbon adsorber was installed. According to 
paragraph (e)(5) of this section, daily monitoring of the replacement 
bed would begin on the 90th day after installation (i.e., 10 days 
earlier than when the exceedance was detected on the previous bed). In 
all of these examples, the initial monitoring of the replacement bed 
within 7 days of installation and the monthly monitoring would proceed 
as set out in paragraph (e)(3) of this section until daily monitoring 
was required.
    (f) For each vapor incinerator, the owner or operator shall comply 
with the monitoring requirements specified below:
    (1) Install, calibrate, maintain, and operate according to the 
manufacturer's specifications a temperature monitoring device equipped 
with a continuous recorder and having an accuracy of 1 
percent of the temperature being monitored expressed in degrees Celsius 
or 0.5  deg.C, whichever is greater.
    (i) Where a vapor incinerator other than a catalytic incinerator is 
used, the temperature monitoring device shall be installed in the 
firebox.
    (ii) Where a catalytic incinerator is used, temperature monitoring 
devices

[[Page 76]]

shall be installed in the gas stream immediately before and after the 
catalyst bed.
    (2) Comply with paragraph (f)(2)(i), paragraph (f)(2)(ii), or 
paragraph (f)(3)(iii) of this section.
    (i) Install, calibrate, maintain and operate according to the 
manufacturer's specifications a flow indicator that provides a record of 
vent stream flow to the incinerator at least once every hour for each 
source. The flow indicator shall be installed in the vent stream from 
each source at a point closest to the inlet of each vapor incinerator 
and before being joined with any other vent stream.
    (ii) Install, calibrate, maintain and operate according to the 
manufacturer's specifications a flow indicator that provides a record of 
vent stream flow away from the vapor incinerator at least once every 15 
minutes. The flow indicator shall be installed in each bypass line, 
immediately downstream of the valve that, if opened, would divert the 
vent stream away from the vapor incinerator.
    (iii) Where a valve that opens a bypass line is secured in the 
closed position with a car seal or a lock-and-key configuration, a flow 
indicator is not required. The owner or operator shall perform a visual 
inspection at least once every month to check the position of the valve 
and the condition of the car seal or lock-and-key configuration. The 
owner or operator shall also record the date and duration of each time 
that the valve was opened and the vent stream diverted away from the 
vapor incinerator.
    (g) In conducting the compliance tests required in Sec. 61.139(c), 
and measurements specified in Sec. 61.139(d)(1), (e)(1) and (h)(3)(ii), 
the owner or operator shall use as reference methods the test methods 
and procedures in appendix A to 40 CFR part 60, or other methods as 
specified in this paragraph, except as specified in Sec. 61.13.
    (1) For compliance tests, as described in Sec. 61.139(c)(1), the 
following provisions apply.
    (i) All tests shall be run under representative emission 
concentration and vent flow rate conditions. For sources with 
intermittent flow rates, representative conditions shall include typical 
emission surges (for example, during the loading of a storage tank).
    (ii) Each test shall consist of three separate runs. These runs will 
be averaged to yield the volumetric flow rates and benzene 
concentrations in the equation in Sec. 61.139(c)(1). Each run shall be a 
minimum of 1 hour.
    (A) For each regenerative carbon adsorber, each run shall take place 
in one adsorption cycle, to include a minimum of 1 hour of sampling 
immediately preceding the initiation of carbon bed regeneration.
    (B) For each non-regenerative carbon adsorber, all runs can occur 
during one adsorption cycle.
    (iii) The measurements during the runs shall be paired so that the 
inlet and outlet to the control device are measured simultaneously.
    (iv) Method 1 or 1A shall be used as applicable for locating 
measurement sites.
    (v) Method 2, 2A, or 2D shall be used as applicable for measuring 
vent flow rates.
    (vi) Method 18 shall be used for determining the benzene 
concentrations (Caj and Cbi). Either follow 
section 7.1, ``Integrated Bag Sampling and Analysis,'' or section 7.2, 
``Direct Interface Sampling and Analysis Procedure.'' A separation 
column constructed of stainless steel, 1.83 m by 3.2 mm, containing 10 
percent 1,2,3-tris (2-cyanoethoxy) propane (TECP) on 80/100 mesh 
Chromosorb P AW, with a column temperature of 80  deg.C, a detector 
temperature of 225  deg.C, and a flow rate of approximately 20 ml/min, 
may produce adequate separations. The analyst can use other columns, 
provided that the precision and accuracy of the analysis of benzene 
standards is not impaired. The analyst shall have available for review 
information confirming that there is adequate resolution of the benzene 
peak.
    (A) If section 7.1 is used, the sample rate shall be adjusted to 
maintain a constant proportion to vent flow rate.
    (B) If section 7.2 is used, then each performance test run shall be 
conducted in intervals of 5 minutes. For each interval ``t,'' readings 
from each measurement shall be recorded, and the flow rate 
(Qaj or Qbi) and the corresponding benzene 
concentration (Caj

[[Page 77]]

or Cbi) shall be determined. The sampling system shall be 
constructed to include a mixing chamber of a volume equal to 5 times the 
sampling flow rate per minute. Each analysis performed by the 
chromatograph will then represent an averaged emission value for a 5-
minute time period. The vent flow rate readings shall be timed to 
account for the total sample system residence time. A dual column, dual 
detector chromatograph can be used to achieve an analysis interval of 5 
minutes. The individual benzene concentrations shall be vent flow rate 
weighted to determine sample run average concentrations. The individual 
vent flow rates shall be time averaged to determine sample run average 
flow rates.
    (2) For testing the benzene concentration at the outlet vent of the 
carbon adsorber as specified under Secs. 61.139(d)(1), (e)(1) and 
(h)(3)(ii), the following provisions apply.
    (i) The measurement shall be conducted over one 5-minute period.
    (ii) The requirements in Sec. 61.139(g)(1)(i) shall apply to the 
extent practicable.
    (iii) The requirements in Sec. 61.139(g)(1)(vi) shall apply. Section 
7.2 of method 18 shall be used as described in Sec. 61.139(g)(1)(vi)(B) 
for benzene concentration measurements.
    (h) For each carbon adsorber, the maximum concentration point shall 
be expressed either as a benzene concentration or organic compound 
concentration level, whichever is to be indicated by the monitoring 
device chosen under Sec. 61.139 (d) or (e).
    (1) For each regenerative carbon adsorber, the owner or operator 
shall determine the maximum concentration point at the following times:
    (i) No later than the deadline for the initial compliance test as 
specified in Sec. 61.139(c)(1);
    (ii) At the request of the Administrator; and
    (iii) At any time chosen by the owner or operator.
    (2) For each non-regenerative carbon adsorber, the owner or operator 
shall determine the maximum concentration point at the following times:
    (i) On the first carbon bed to be installed in the adsorber;
    (ii) At the request of the Administrator;
    (iii) On the next carbon bed after the maximum concentration point 
has been exceeded (before the scheduled replacement time) for each of 
three previous carbon beds in the adsorber since the most recent 
determination; and
    (iv) At any other time chosen by the owner or operator.
    (3) The maximum concentration point for each carbon adsorber shall 
be determined through the simultaneous measurement of the outlet of the 
carbon adsorber with the monitoring device and method 18, except as 
allowed in paragraph (h)(4) of this section.
    (i) Several data points shall be collected according to a schedule 
determined by the owner or operator. The schedule shall be designed to 
take frequent samples near the expected maximum concentration point.
    (ii) Each data point shall consist of one 5-minute benzene 
concentration measurement using method 18 as specified in 
Sec. 61.139(g)(2), and of a simultaneous measurement by the monitoring 
device. The monitoring device measurement shall be conducted according 
to Sec. 61.139 (d) or (e), whichever is applicable.
    (iii) The maximum concentration point shall be the concentration 
level, as indicated by the monitoring device, for the last data point at 
which the benzene concentration is less than 2 percent of the average 
value of the benzene concentration at the inlet to the carbon adsorber 
during the most recent compliance test.
    (4) If the maximum concentration point is expressed as a benzene 
concentration, the owner or operator may determine it by calibrating the 
monitoring device with benzene at a concentration that is 2 percent of 
the average benzene concentration measured at the inlet to the carbon 
adsorber during the most recent compliance test. The reading on the 
monitoring device corresponding to the calibration concentration shall 
be the maximum concentration point. This method of determination would 
affect the owner or operator as follows:

[[Page 78]]

    (i) For a regenerative carbon adsorber, the owner or operator is 
exempt from the provisions in paragraph (h)(3) of this section.
    (ii) For a non-regenerative carbon adsorber, the owner or operator 
is required to collect the data points in paragraph (h)(3) of this 
section with only the monitoring device, and is exempt from the 
simultaneous method 18 measurement.
    (5) For each non-regenerative carbon adsorber, the demonstrated bed 
life shall be the carbon bed life, measured in days from the time the 
bed is installed until the maximum concentration point is reached, for 
the carbon bed that is used to determine the maximum concentration 
point.

    (c) Procedures for asbestos emission control. Each owner or operator 
of a demolition or renovation activity to whom this paragraph applies, 
according to paragraph (a) of this section, shall comply with the 
following procedures:
    (1) Remove all RACM from a facility being demolished or renovated 
before any activity begins that would break up, dislodge, or similarly 
disturb the material or preclude access to the material for subsequent 
removal. RACM need not be removed before demolition if:
    (i) It is Category I nonfriable ACM that is not in poor condition 
and is not friable.
    (ii) It is on a facility component that is encased in concrete or 
other similarly hard material and is adequately wet whenever exposed 
during demolition; or
    (iii) It was not accessible for testing and was, therefore, not 
discovered until after demolition began and, as a result of the 
demolition, the material cannot be safely removed. If not removed for 
safety reasons, the exposed RACM and any asbestos-contaminated debris 
must be treated as asbestos-containing waste material and adequately wet 
at all times until disposed of.
    (iv) They are Category II nonfriable ACM and the probability is low 
that the materials will become crumbled, pulverized, or reduced to 
powder during demolition.
    (2) When a facility component that contains, is covered with, or is 
coated with RACM is being taken out of the facility as a unit or in 
sections:
    (i) Adequately wet all RACM exposed during cutting or disjoining 
operations; and
    (ii) Carefully lower each unit or section to the floor and to ground 
level, not dropping, throwing, sliding, or otherwise damaging or 
disturbing the RACM.
    (3) When RACM is stripped from a facility component while it remains 
in place in the facility, adequately wet the RACM during the stripping 
operation.
    (i) In renovation operations, wetting is not required if:
    (A) The owner or operator has obtained prior written approval from 
the Administrator based on a written application that wetting to comply 
with

[[Page 89]]

this paragraph would unavoidably damage equipment or present a safety 
hazard; and
    (B) The owner or operator uses of the following emission control 
methods:
    (1) A local exhaust ventilation and collection system designed and 
operated to capture the particulate asbestos material produced by the 
stripping and removal of the asbestos materials. The system must exhibit 
no visible emissions to the outside air or be designed and operated in 
accordance with the requirements in Sec. 61.152.
    (2) A glove-bag system designed and operated to contain the 
particulate asbestos material produced by the stripping of the asbestos 
materials.
    (3) Leak-tight wrapping to contain all RACM prior to dismantlement.
    (ii) In renovation operations where wetting would result in 
equipment damage or a safety hazard, and the methods allowed in 
paragraph (c)(3)(i) of this section cannot be used, another method may 
be used after obtaining written approval from the Administrator based 
upon a determination that it is equivalent to wetting in controlling 
emissions or to the methods allowed in paragraph (c)(3)(i) of this 
section.
    (iii) A copy of the Administrator's written approval shall be kept 
at the worksite and made available for inspection.
    (4) After a facility component covered with, coated with, or 
containing RACM has been taken out of the facility as a unit or in 
sections pursuant to paragraph (c)(2) of this section, it shall be 
stripped or contained in leak-tight wrapping, except as described in 
paragraph (c)(5) of this section. If stripped, either:
    (i) Adequately wet the RACM during stripping; or
    (ii) Use a local exhaust ventilation and collection system designed 
and operated to capture the particulate asbestos material produced by 
the stripping. The system must exhibit no visible emissions to the 
outside air or be designed and operated in accordance with the 
requirements in Sec. 61.152.
    (5) For large facility components such as reactor vessels, large 
tanks, and steam generators, but not beams (which must be handled in 
accordance with paragraphs (c)(2), (3), and (4) of this section), the 
RACM is not required to be stripped if the following requirements are 
met:
    (i) The component is removed, transported, stored, disposed of, or 
reused without disturbing or damaging the RACM.
    (ii) The component is encased in a leak-tight wrapping.
    (iii) The leak-tight wrapping is labeled according to 
Sec. 61.149(d)(1)(i), (ii), and (iii) during all loading and unloading 
operations and during storage.
    (6) For all RACM, including material that has been removed or 
stripped:
    (i) Adequately wet the material and ensure that it remains wet until 
collected and contained or treated in preparation for disposal in 
accordance with Sec. 61.150; and
    (ii) Carefully lower the material to the ground and floor, not 
dropping, throwing, sliding, or otherwise damaging or disturbing the 
material.
    (iii) Transport the material to the ground via leak-tight chutes or 
containers if it has been removed or stripped more than 50 feet above 
ground level and was not removed as units or in sections.
    (iv) RACM contained in leak-tight wrapping that has been removed in 
accordance with paragraphs (c)(4) and (c)(3)(i)(B)(3) of this section 
need not be wetted.
    (7) When the temperature at the point of wetting is below 0  deg.C 
(32  deg.F):
    (i) The owner or operator need not comply with paragraph (c)(2)(i) 
and the wetting provisions of paragraph (c)(3) of this section.
    (ii) The owner or operator shall remove facility components 
containing, coated with, or covered with RACM as units or in sections to 
the maximum extent possible.
    (iii) During periods when wetting operations are suspended due to 
freezing temperatures, the owner or operator must record the temperature 
in the area containing the facility components at the beginning, middle, 
and end of each workday and keep daily temperature records available for 
inspection by the Administrator during normal business hours at the 
demolition

[[Page 90]]

or renovation site. The owner or operator shall retain the temperature 
records for at least 2 years.
    (8) Effective 1 year after promulgation of this regulation, no RACM 
shall be stripped, removed, or otherwise handled or disturbed at a 
facility regulated by this section unless at least one on-site 
representative, such as a foreman or management-level person or other 
authorized representative, trained in the provisions of this regulation 
and the means of complying with them, is present. Every 2 years, the 
trained on-site individual shall receive refresher training in the 
provisions of this regulation. The required training shall include as a 
minimum: applicability; notifications; material identification; control 
procedures for removals including, at least, wetting, local exhaust 
ventilation, negative pressure enclosures, glove-bag procedures, and 
High Efficiency Particulate Air (HEPA) filters; waste disposal work 
practices; reporting and recordkeeping; and asbestos hazards and worker 
protection. Evidence that the required training has been completed shall 
be posted and made available for inspection by the Administrator at the 
demolition or renovation site.
    (9) For facilities described in paragraph (a)(3) of this section, 
adequately wet the portion of the facility that contains RACM during the 
wrecking operation.
    (10) If a facility is demolished by intentional burning, all RACM 
including Category I and Category II nonfriable ACM must be removed in 
accordance with the NESHAP before burning.

Sec. 61.151  Standard for inactive waste disposal sites for asbestos mills and manufacturing and fabricating operations.

    Each owner or operator of any inactive waste disposal site that was 
operated by sources covered under Sec. 61.142, 61.144, or 61.147 and 
received deposits of asbestos-containing waste material generated by the 
sources, shall:
    (a) Comply with one of the following:
    (1) Either discharge no visible emissions to the outside air from an 
inactive waste disposal site subject to this paragraph; or
    (2) Cover the asbestos-containing waste material with at least 15 
centimeters (6 inches) of compacted nonasbestos-containing material, and 
grow and maintain a cover of vegetation on the area adequate to prevent 
exposure of the asbestos-containing waste material. In desert areas 
where vegetation would be difficult to maintain, at least 8 additional 
centimeters (3 inches) of well-graded, nonasbestos crushed rock may be 
placed on top of the final cover instead of vegetation and maintained to 
prevent emissions; or
    (3) Cover the asbestos-containing waste material with at least 60 
centimeters (2 feet) of compacted nonasbestos-containing material, and 
maintain it to prevent exposure of the asbestos-containing waste; or
    (4) For inactive waste disposal sites for asbestos tailings, a 
resinous or petroleum-based dust suppression agent that effectively 
binds dust to control surface air emissions may be used instead of the 
methods in paragraphs (a) (1), (2), and (3) of this section. Use the 
agent in the manner and frequency recommended for the particular 
asbestos tailings by the manufacturer of the dust suppression agent to 
achieve and maintain dust control. Obtain prior written approval of the 
Administrator to use other equally effective dust suppression agents. 
For purposes of this paragraph, any used, spent, or other waste oil is 
not considered a dust suppression agent.
    (b) Unless a natural barrier adequately deters access by the general 
public, install and maintain warning signs and fencing as follows, or 
comply with paragraph (a)(2) or (a)(3) of this section.
    (1) Display warning signs at all entrances and at intervals of 100 m

Sec. 61.155  Standard for operations that convert asbestos-containing waste material into nonasbestos (asbestos-free) material.

    Each owner or operator of an operation that converts RACM and 
asbestos-containing waste material into nonasbestos (asbestos-free) 
material shall:
    (a) Obtain the prior written approval of the Administrator to 
construct the facility. To obtain approval, the owner or operator shall 
provide the Administrator with the following information:
    (1) Application to construct pursuant to Sec. 61.07.
    (2) In addition to the information requirements of Sec. 61.07(b)(3), 
a
    (i) Description of waste feed handling and temporary storage.
    (ii) Description of process operating conditions.
    (iii) Description of the handling and temporary storage of the end 
product.
    (iv) Description of the protocol to be followed when analyzing 
output materials by transmission electron microscopy.
    (3) Performance test protocol, including provisions for obtaining 
information required under paragraph (b) of this section.
    (4) The Administrator may require that a demonstration of the 
process be performed prior to approval of the application to construct.
    (b) Conduct a start-up performance test. Test results shall include:
    (1) A detailed description of the types and quantities of 
nonasbestos material,

[[Page 105]]

RACM, and asbestos-containing waste material processed, e.g., asbestos 
cement products, friable asbestos insulation, plaster, wood, plastic, 
wire, etc. Test feed is to include the full range of materials that will 
be encountered in actual operation of the process.
    (2) Results of analyses, using polarized light microscopy, that 
document the asbestos content of the wastes processed.
    (3) Results of analyses, using transmission electron microscopy, 
that document that the output materials are free of asbestos. Samples 
for analysis are to be collected as 8-hour composite samples (one 200-
gram (7-ounce) sample per hour), beginning with the initial introduction 
of RACM or asbestos-containing waste material and continuing until the 
end of the performance test.
    (4) A description of operating parameters, such as temperature and 
residence time, defining the full range over which the process is 
expected to operate to produce nonasbestos (asbestos-free) materials. 
Specify the limits for each operating parameter within which the process 
will produce nonasbestos (asbestos-free) materials.
    (5) The length of the test.
    (c) During the initial 90 days of operation,
    (1) Continuously monitor and log the operating parameters identified 
during start-up performance tests that are intended to ensure the 
production of nonasbestos (asbestos-free) output material.
    (2) Monitor input materials to ensure that they are consistent with 
the test feed materials described during start-up performance tests in 
paragraph (b)(1) of this section.
    (3) Collect and analyze samples, taken as 10-day composite samples 
(one 200-gram (7-ounce) sample collected every 8 hours of operation) of 
all output material for the presence of asbestos. Composite samples may 
be for fewer than 10 days. Transmission electron microscopy (TEM) shall 
be used to analyze the output material for the presence of asbestos. 
During the initial 90-day period, all output materials must be stored 
on-site until analysis shows the material to be asbestos-free or 
disposed of as asbestos-containing waste material according to 
Sec. 61.150.
    (d) After the initial 90 days of operation,
    (1) Continuously monitor and record the operating parameters 
identified during start-up performance testing and any subsequent 
performance testing. Any output produced during a period of deviation 
from the range of operating conditions established to ensure the 
production of nonasbestos (asbestos-free) output materials shall be:
    (i) Disposed of as asbestos-containing waste material according to 
Sec. 61.150, or
    (ii) Recycled as waste feed during process operation within the 
established range of operating conditions, or
    (iii) Stored temporarily on-site in a leak-tight container until 
analyzed for asbestos content. Any product material that is not 
asbestos-free shall be either disposed of as asbestos-containing waste 
material or recycled as waste feed to the process.
    (2) Collect and analyze monthly composite samples (one 200-gram (7-
ounce) sample collected every 8 hours of operation) of the output 
material. Transmission electron microscopy shall be used to analyze the 
output material for the presence of asbestos.
    (e) Discharge no visible emissions to the outside air from any part 
of the operation, or use the methods specified by Sec. 61.152 to clean 
emissions containing particulate asbestos material before they escape 
to, or are vented to, the outside air.
    (f) Maintain records on-site and include the following information:
    (1) Results of start-up performance testing and all subsequent 
performance testing, including operating parameters, feed 
characteristic, and analyses of output materials.
    (2) Results of the composite analyses required during the initial 90 
days of operation under Sec. 61.155(c).
    (3) Results of the monthly composite analyses required under 
Sec. 61.155(d).
    (4) Results of continuous monitoring and logs of process operating 
parameters required under Sec. 61.155 (c) and (d).
    (5) The information on waste shipments received as required in 
Sec. 61.154(e).
    (6) For output materials where no analyses were performed to 
determine the presence of asbestos, record the name and location of the 
purchaser or

[[Page 106]]

disposal site to which the output materials were sold or deposited, and 
the date of sale or disposal.
    (7) Retain records required by paragraph (f) of this section for at 
least 2 years.
    (g) Submit the following reports to the Administrator:
    (1) A report for each analysis of product composite samples 
performed during the initial 90 days of operation.
    (2) A quarterly report, including the following information 
concerning activities during each consecutive 3-month period:
    (i) Results of analyses of monthly product composite samples.
    (ii) A description of any deviation from the operating parameters 
established during performance testing, the duration of the deviation, 
and steps taken to correct the deviation.
    (iii) Disposition of any product produced during a period of 
deviation, including whether it was recycled, disposed of as asbestos-
containing waste material, or stored temporarily on-site until analyzed 
for asbestos content.
    (iv) The information on waste disposal activities as required in 
Sec. 61.154(f).
    (h) Nonasbestos (asbestos-free) output material is not subject to 
any of the provisions of this subpart. Output materials in which 
asbestos is detected, or output materials produced when the operating 
parameters deviated from those established during the start-up 
performance testing, unless shown by TEM analysis to be asbestos-free, 
shall be considered to be asbestos-containing waste and shall be handled 
and disposed of according to Secs. 61.150 and 61.154 or reprocessed 
while all of the established operating parameters are being met.

   Appendix A to Subpart M--Interpretive Rule Governing Roof Removal 
                               Operations

                 I. Applicability of the Asbestos NESHAP

    1.1. Asbestos-containing material (ACM) is material containing more 
than one percent asbestos as determined using the methods specified in 
appendix E, subpart E, 40 CFR part 763, section 1, Polarized Light 
Microscopy. The NESHAP classifies ACM as either ``friable'' or 
``nonfriable''. Friable ACM is ACM that, when dry, can be crumbled, 
pulverized or reduced to powder by hand pressure. Nonfriable ACM is ACM 
that, when dry, cannot be crumbled, pulverized or reduced to powder by 
hand pressure.
    1.2. Nonfriable ACM is further classified as either Category I ACM 
or Category II ACM. Category I ACM and Category II ACM are distinguished 
from each other by their potential to release fibers when damaged. 
Category I ACM includes asbestos-containing gaskets, packings, resilient 
floor coverings, resilient floor covering mastic, and asphalt roofing 
products containing more than one percent asbestos. Asphalt roofing 
products which may contain asbestos include built-up roofing; asphalt-
containing single ply membrane systems; asphalt shingles; asphalt-
containing underlayment felts; asphalt-containing roof coatings and 
mastics; and asphalt-containing base flashings. ACM roofing products 
that use other bituminous or resinous binders (such as coal tars or 
pitches) are also considered to be Category I ACM. Category II ACM 
includes all other nonfriable ACM, for example, asbestos-cement (A/C) 
shingles, A/C tiles, and transite boards or panels containing more than 
one percent asbestos. Generally speaking, Category II ACM is more likely 
to become friable when damaged than is Category I ACM. The applicability 
of the NESHAP to Category I and II ACM depends on: (1) the condition of 
the material at the time of demolition or renovation, (2) the nature of 
the operation to which the material will be subjected, (3) the amount of 
ACM involved.
    1.3. Asbestos-containing material regulated under the NESHAP is 
referred to as ``regulated asbestos-containing material'' (RACM). RACM 
is defined in Sec. 61.141 of the NESHAP and includes: (1) friable 
asbestos-containing material; (2) Category I nonfriable ACM that has 
become friable; (3) Category I nonfriable ACM that has been or will be 
sanded, ground, cut, or abraded; or (4) Category II nonfriable ACM that 
has already been or is likely to become crumbled, pulverized, or reduced 
to powder. If the coverage threshold for RACM is met or exceeded in a 
renovation or demolition operation, then all friable ACM in the 
operation, and in certain situations, nonfriable ACM in the operation, 
are subject to the NESHAP.

      A. Threshold Amounts of Asbestos-Containing Roofing Material

    1.A.1. The NESHAP does not cover roofing projects on single family 
homes or on residential buildings containing four or fewer dwelling 
units. 40 CFR 61.141. For other roofing renovation projects, if the 
total asbestos-containing roof area undergoing renovation is less than 
160 ft 2, the NESHAP does not apply, regardless of the 
removal method to be used, the type of material (Category I or II), or 
its condition (friable versus nonfriable). 40 CFR 61.145(a)(4). However, 
EPA would recommend the use of methods that damage asbestos-containing 
roofing material as little as possible. EPA has determined that where a 
rotating blade (RB) roof cutter or equipment that similarly damages the 
roofing material is used to remove Category I nonfriable asbestos-
containing roofing material, the removal of 5580 ft 2 of that 
material will create 160 ft 2 of RACM. For the purposes of 
this interpretive rule, ``RB roof cutter'' means an engine-powered roof 
cutting machine with one or more rotating cutting blades the edges of 
which are blunt. (Equipment with blades having sharp or tapered edges, 
and/or which does not use a rotating blade, is used for ``slicing'' 
rather than ``cutting'' the roofing material; such equipment is not 
included in the term ``RB roof cutter''.) Therefore, it is EPA's 
interpretation that when an RB roof cutter or equipment that similarly 
damages the roofing material is used to remove Category I nonfriable 
asbestos-containing roofing material, any project that is 5580 ft 
2 or greater is subject to the NESHAP; conversely, it is 
EPA's interpretation that when an RB roof cutter or equipment that 
similarly damages the roofing material is used to remove Category I 
nonfriable asbestos-containing roofing material in a roof removal 
project that is less than 5580 ft 2, the project is not 
subject to the NESHAP, except that notification is always required for 
demolitions. EPA further construes the NESHAP to mean that if slicing or 
other methods that do not sand, grind, cut or abrade will be used on 
Category I nonfriable ACM, the NESHAP does not apply, regardless of the 
area of roof to be removed.
    1.A.2. For asbestos cement (A/C) shingles (or other Category II 
roofing material), if the area of the roofing material to be removed is 
at least 160 ft 2 and the removal methods will crumble, 
pulverize, reduce to powder, or contaminate with RACM (from other ACM 
that has been crumbled, pulverized or reduced to

[[Page 108]]

powder) 160 ft 2 or more of such roofing material, the 
removal is subject to the NESHAP. Conversely, if the area of the A/C 
shingles (or other Category II roofing materials) to be removed is less 
than 160 ft 2, the removal is not subject to the NESHAP 
regardless of the removal method used, except that notification is 
always required for demolitions. 40 CFR 61.145(a). However, EPA would 
recommend the use of methods that damage asbestos-containing roofing 
material as little as possible. If A/C shingles (or other Category II 
roofing materials) are removed without 160 ft 2 or more of 
such roofing material being crumbled, pulverized, reduced to powder, or 
contaminated with RACM (from other ACM that has been crumbled, 
pulverized or reduced to powder), the operation is not subject to the 
NESHAP, even where the total area of the roofing material to be removed 
exceeds 160 ft 2; provided, however, that if the renovation 
includes other operations involving RACM, the roof removal operation is 
covered if the total area of RACM from all renovation activities exceeds 
160 ft 2. See the definition of regulated asbestos-containing 
material (RACM), 40 CFR 61.141.
    1.A.3. Only roofing material that meets the definition of ACM can 
qualify as RACM subject to the NESHAP. Therefore, to determine if a 
removal operation that meets or exceeds the coverage threshold is 
subject to the NESHAP, any suspect roofing material (i.e. roofing 
material that may be ACM) should be tested for asbestos. If any such 
roofing material contains more than one percent asbestos and if the 
removal operation is covered by the NESHAP, then EPA must be notified 
and the work practices in Sec. 61.145(c) must be followed. In EPA's 
view, if a removal operation involves at least the threshold level of 
suspect material, a roofing contractor may choose not to test for 
asbestos if the contractor follows the notification and work practice 
requirements of the NESHAP.

            B. A/C Shingle Removal (Category II ACM Removal)

    1.B.1. A/C shingles, which are Category II nonfriable ACM, become 
regulated ACM if the material has a high probability of becoming or has 
become crumbled, pulverized or reduced to powder by the forces expected 
to act on the material in the course of demolition or renovation 
operations. 40 CFR 61.141. However, merely breaking an A/C shingle (or 
any other category II ACM) that is not friable may not necessarily cause 
the material to become RACM. A/C shingles are typically nailed to 
buildings on which they are attached. EPA believes that the extent of 
breakage that will normally result from carefully removing A/C shingles 
and lowering the shingles to the ground will not result in crumbling, 
pulverizing or reducing the shingles to powder. Conversely, the extent 
of breakage that will normally occur if the A/C shingles are dropped 
from a building or scraped off of a building with heavy machinery would 
cause the shingles to become RACM. EPA therefore construes the NESHAP to 
mean that the removal of A/C shingles that are not friable, using 
methods that do not crumble, pulverize, or reduce the A/C shingles to 
powder (such as pry bars, spud bars and shovels to carefully pry the 
material), is not subject to the NESHAP provided that the A/C shingles 
are properly handled during and after removal, as discussed in this 
paragraph and the asbestos NESHAP. This interpretation also applies to 
other Category II nonfriable asbestos-containing roofing materials.

 C. Cutting vs. Slicing and Manual Methods for Removal of Category I ACM

    1.C.1. Because of damage to the roofing material, and the potential 
for fiber release, roof removal operations using rotating blade (RB) 
roof cutters or other equipment that sand, grind, cut or abrade the roof 
material are subject to the NESHAP. As EPA interprets the NESHAP, the 
use of certain manual methods (using equipment such as axes, hatchets, 
or knives, spud bars, pry bars, and shovels, but not saws) or methods 
that slice, shear, or punch (using equipment such as a power slicer or 
power plow) does not constitute ``cutting, sanding, grinding or 
abrading.'' This is because these methods do not destroy the structural 
matrix or integrity of the material such that the material is crumbled, 
pulverized or reduced to powder. Hence, it is EPA's interpretation that 
when such methods are used, assuming the roof material is not friable, 
the removal operation is not subject to the regulation.
    1.C.2. Power removers or power tear-off machines are typically used 
to pry the roofing material up from the deck after the roof membrane has 
been cut. It is EPA's interpretation that when these machines are used 
to pry roofing material up, their use is not regulated by the NESHAP.
    1.C.3. As noted previously, the NESHAP only applies to the removal 
of asbestos-containing roofing materials. Thus, the NESHAP does not 
apply to the use of RB cutters to remove non-asbestos built up roofing 
(BUR). On roofs containing some asbestos-containing and some non-
asbestos-containing materials, coverage under the NESHAP depends on the 
methods used to remove each type of material in addition to other 
coverage thresholds specified above. For example, it is not uncommon for 
existing roofs to be made of non-asbestos BUR and base flashings that do 
contain asbestos. In that situation, EPA construes the NESHAP to be 
inapplicable to the removal of the non-asbestos BUR using an RB cutter 
so long as the RB cutter is not used to cut 5580

[[Page 109]]

ft\2\ or more of the asbestos-containing base flashing or other 
asbestos-containing material into sections. In addition, the use of 
methods that slice, shear, punch or pry could then be used to remove the 
asbestos flashings and not trigger coverage under the NESHAP.

                            II. Notification

    2.1. Notification for a demolition is always required under the 
NESHAP. However, EPA believes that few roof removal jobs constitute 
``demolitions'' as defined in the NESHAP (Sec. 61.141). In particular, 
it is EPA's view that the removal of roofing systems (i.e., the roof 
membrane, insulation, surfacing, coatings, flashings, mastic, shingles, 
and felt underlayment), when such removal is not a part of a demolition 
project, constitutes a ``renovation'' under the NESHAP. If the operation 
is a renovation, and Category I roofing material is being removed using 
either manual methods or slicing, notification is not required by the 
NESHAP. If Category II material is not friable and will be removed 
without crumbling, pulverizing, or reducing it to powder, no 
notification is required. Also, if the renovation involves less than the 
threshold area for applicability as discussed above, then no 
notification is required. However, if a roof removal meets the 
applicability and threshold requirements under the NESHAP, then EPA (or 
the delegated agency) must be notified in advance of the removal in 
accordance with the requirements of Sec. 61.145(b), as follows:
     Notification must be given in writing at least 10 working 
days in advance and must include the information in Sec. 61.145(b)(4), 
except for emergency renovations as discussed below.
     The notice must be updated as necessary, including, for 
example, when the amount of asbestos-containing roofing material 
reported changes by 20 percent or more.
     EPA must be notified if the start date of the roof removal 
changes. If the start date of a roof removal project is changed to an 
earlier date, EPA must be provided with a written notice of the new 
start date at least 10 working days in advance. If the start date 
changes to a later date, EPA must be notified by telephone as soon as 
possible before the original start date and a written notice must be 
sent as soon as possible.
     For emergency renovations (as defined in Sec. 61.141), 
where work must begin immediately to avoid safety or public health 
hazards, equipment damage, or unreasonable financial burden, the 
notification must be postmarked or delivered to EPA as soon as possible, 
but no later than the following work day.

                     III. Emission Control Practices

   A. Requirements to Adequately Wet and Discharge No Visible Emission

    3.A.1. The principal controls contained in the NESHAP for removal 
operations include requirements that the affected material be adequately 
wetted, and that asbestos waste be handled, collected, and disposed of 
properly. The requirements for disposal of waste materials are discussed 
separately in section IV below. The emission control requirements 
discussed in this section III apply only to roof removal operations that 
are covered by the NESHAP as set forth in Section I above.
    3.A.2. For any operation subject to the NESHAP, the regulation 
(Secs. 61.145(c)(2)(i), (3), (6)(i)) requires that RACM be adequately 
wet (as defined in Sec. 61.141) during the operation that damages or 
disturbs the asbestos material until collected for disposal.
    3.A.3. When using an RB roof cutter (or any other method that sands, 
grinds, cuts or abrades the roofing material) to remove Category I 
asbestos-containing roofing material, the emission control requirements 
of Sec. 61.145(c) apply as discussed in Section I above. EPA will 
consider a roof removal project to be in compliance with the 
``adequately wet'' and ``discharge no visible emission'' requirements of 
the NESHAP if the RB roof cutter is equipped and operated with the 
following: (1) a blade guard that completely encloses the blade and 
extends down close to the roof surface; and (2) a device for spraying a 
fine mist of water inside the blade guard, and which device is in 
operation during the cutting of the roof.

                 B. Exemptions From Wetting Requirements

    3.B.1. The NESHAP provides that, in certain instances, wetting may 
not be required during the cutting of Category I asbestos roofing 
material with an RB roof cutter. If EPA determines in accordance with 
Sec. 61.145(c)(3)(i), that wetting will unavoidably damage the building, 
equipment inside the building, or will present a safety hazard while 
stripping the ACM from a facility component that remains in place, the 
roof removal operation will be exempted from the requirement to wet 
during cutting. EPA must have sufficient written information on which to 
base such a decision. Before proceeding with a dry removal, the 
contractor must have received EPA's written approval. Such exemptions 
will be made on a case-by-case basis.
    3.B.2. It is EPA's view that, in most instances, exemptions from the 
wetting requirements are not necessary. Where EPA grants an exemption 
from wetting because of the potential for damage to the building, damage 
to equipment within the building or a safety hazard, the NESHAP 
specifies alternative control methods (Sec. 61.145(c)(3)(i)(B)).

[[Page 110]]

Alternative control methods include (a) the use of local exhaust 
ventilation systems that capture the dust, and do not produce visible 
emissions, or (b) methods that are designed and operated in accordance 
with the requirements of Sec. 61.152, or (c) other methods that have 
received the written approval of EPA. EPA will consider an alternative 
emission control method in compliance with the NESHAP if the method has 
received written approval from EPA and the method is being implemented 
consistent with the approved procedures (Sec. 61.145(c)(3)(ii) or 
Sec. 61.152(b)(3)).
    3.B.3. An exemption from wetting is also allowed when the air or 
roof surface temperature at the point of wetting is below freezing, as 
specified in Sec. 61.145(c)(7). If freezing temperatures are indicated 
as the reason for not wetting, records must be kept of the temperature 
at the beginning, middle and end of the day on which wetting is not 
performed and the records of temperature must be retained for at least 2 
years. 42 CFR Sec. 61.145(c)(7)(iii). It is EPA's interpretation that in 
such cases, no written application to, or written approval by the 
Administrator is needed for using emission control methods listed in 
Sec. 61.145(c)(3)(i)(B), or alternative emission control methods that 
have been previously approved by the Administrator. However, such 
written application or approval is required for alternative emission 
control methods that have not been previously approved. Any dust and 
debris collected from cutting must still be kept wet and placed in 
containers. All of the other requirements for notification and waste 
disposal would continue to apply as described elsewhere in this notice 
and the Asbestos NESHAP.

                    C. Waste Collection and Handling

    3.C.1. It is EPA's interpretation that waste resulting from slicing 
and other methods that do not cut, grind, sand or abrade Category I 
nonfriable asbestos-containing roofing material is not subject to the 
NESHAP and can be disposed of as nonasbestos waste. EPA further 
construes the NESHAP to provide that if Category II roofing material 
(such as A/C shingles) is removed and disposed of without crumbling, 
pulverizing, or reducing it to powder, the waste from the removal is not 
subject to the NESHAP waste disposal requirements. EPA also interprets 
the NESHAP to be inapplicable to waste resulting from roof removal 
operations that do not meet or exceed the coverage thresholds described 
in section I above. Of course, other State, local, or Federal 
regulations may apply.
    3.C.2. It is EPA's interpretation that when an RB roof cutter, or 
other method that similarly damages the roofing material, is used to cut 
Category I asbestos containing roofing material, the damaged material 
from the cut (the sawdust or debris) is considered asbestos containing 
waste subject to Sec. 61.150 of the NESHAP, provided the coverage 
thresholds discussed above in section 1 are met or exceeded. This 
sawdust or debris must be disposed of at a disposal site operated in 
accordance with the NESHAP. It is also EPA's interpretation of the 
NESHAP that if the remainder of the roof is free of the sawdust and 
debris generated by the cutting, or if such sawdust or debris is 
collected as discussed below in paragraphs 3.C.3, 3.C.4, 3.C.5 and 
3.C.6, the remainder of the roof can be disposed of as nonasbestos waste 
because it is considered to be Category I nonfriable material (as long 
as the remainder of the roof is in fact nonasbestos material or if it is 
Category I asbestos material and the removal methods do not further 
sand, grind, cut or abrade the roof material). EPA further believes that 
if the roof is not cleaned of such sawdust or debris, i.e., it is 
contaminated, then it must be treated as asbestos-containing waste 
material and be handled in accordance with Sec. 61.150.
    3.C.3. In order to be in compliance with the NESHAP while using an 
RB roof cutter (or device that similarly damages the roofing material) 
to cut Category I asbestos containing roofing material, the dust and 
debris resulting from the cutting of the roof should be collected as 
soon as possible after the cutting operation, and kept wet until 
collected and placed in leak-tight containers. EPA believes that where 
the blade guard completely encloses the blade and extends down close to 
the roof surface and is equipped with a device for spraying a fine mist 
of water inside the blade guard, and the spraying device is in operation 
during the cutting, most of the dust and debris from cutting will be 
confined along the cut. The most efficient methods to collect the dust 
and debris from cutting are to immediately collect or vacuum up the 
damaged material where it lies along the cut using a filtered vacuum 
cleaner or debris collector that meets the requirements of 40 CFR 61.152 
to clean up as much of the debris as possible, or to gently sweep up the 
bulk of the debris, and then use a filtered vacuum cleaner that meets 
the requirements of 40 CFR 61.152 to clean up as much of the remainder 
of the debris as possible. On smooth surfaced roofs (nonaggregate 
roofs), sweeping up the debris and then wet wiping the surface may be 
done in place of using a filtered vacuum cleaner. It is EPA's view that 
if these decontamination procedures are followed, the remaining roofing 
material does not have to be collected and disposed of as asbestos 
waste. Additionally, it is EPA's view that where such decontamination 
procedures are followed, if the remaining portions of the roof are non-
asbestos or Category I nonfriable asbestos material, and if the 
remaining portions are removed using removal methods that slice, shear, 
punch or

[[Page 111]]

pry, as discussed in section 1.C above, then the remaining portions do 
not have to be collected and disposed of as asbestos waste and the 
NESHAP's no visible emissions and adequately wet requirements are not 
applicable to the removal of the remaining portions. In EPA's 
interpretation, the failure of a filtered vacuum cleaner or debris 
collector to collect larger chunks or pieces of damaged roofing material 
created by the RB roof cutter does not require the remaining roofing 
material to be handled and disposed of as asbestos waste, provided that 
such visible chunks or pieces of roofing material are collected (e.g. by 
gentle sweeping) and disposed of as asbestos waste. Other methods of 
decontamination may not be adequate, and should be approved by the local 
delegated agency.
    3.C.4. In EPA's interpretation, if the debris from the cutting is 
not collected immediately, it will be necessary to lightly mist the dust 
or debris, until it is collected, as discussed above, and placed in 
containers. The dust or debris should be lightly misted frequently 
enough to prevent the material from drying, and to prevent airborne 
emissions, prior to collection as described above. It is EPA's 
interpretation of the NESHAP that if these procedures are followed, the 
remaining roofing material does not have to be collected and disposed of 
as asbestos waste, as long as the remaining roof material is in fact 
nonasbestos material or if it is Category I asbestos material and the 
removal methods do not further sand, grind, cut or abrade the roof 
material.
    3.C.5. It is EPA's interpretation that, provided the roofing 
material is not friable prior to the cutting operation, and provided the 
roofing material has not been made friable by the cutting operation, the 
appearance of rough, jagged or damaged edges on the remaining roofing 
material, due to the use of an RB roof cutter, does not require that 
such remaining roofing material be handled and disposed of as asbestos 
waste. In addition, it is also EPA's interpretation that if the sawdust 
or debris generated by the use of an RB roof cutter has been collected 
as discussed in paragraphs 3.C.3, 3.C.4 and 3.C.6, the presence of dust 
along the edge of the remaining roof material does not render such 
material ``friable'' for purposes of this interpretive rule or the 
NESHAP, provided the roofing material is not friable prior to the 
cutting operation, and provided that the remaining roofing material near 
the cutline has not been made friable by the cutting operation. Where 
roofing material near the cutline has been made friable by the use of 
the RB cutter (i.e. where such remaining roofing material near the 
cutline can be crumbled, pulverized or reduced to powder using hand 
pressure), it is EPA's interpretation that the use of an encapsulant 
will ensure that such friable material need not be treated or disposed 
of as asbestos containing waste material. The encapsulant may be applied 
to the friable material after the roofing material has been collected 
into stacks for subsequent disposal as nonasbestos waste. It is EPA's 
view that if the encapsulation procedure set forth in this paragraph is 
followed in operations where roofing material near the cutline has been 
rendered friable by the use of an RB roof cutter, and if the 
decontamination procedures set forth in paragraph 3.C.3 have been 
followed, the NESHAP's no visible emissions and adequately wet 
requirements would be met for the removal, handling and disposal of the 
remaining roofing material.
    3.C.6. As one way to comply with the NESHAP, the dust and debris 
from cutting can be placed in leak-tight containers, such as plastic 
bags, and the containers labeled using warning labels required by OSHA 
(29 CFR 1926.58). In addition, the containers must have labels that 
identify the waste generator (such as the name of the roofing 
contractor, abatement contractor, and/or building owner or operator) and 
the location of the site at which the waste was generated.

                           IV. Waste Disposal

                        A. Disposal Requirements

    4.A.1. Section 61.150(b) requires that, as soon as is practical, all 
collected dust and debris from cutting as well as any contaminated 
roofing squares, must be taken to a landfill that is operated in 
accordance with Sec. 61.154 or to an EPA-approved site that converts 
asbestos waste to nonasbestos material in accordance with Sec. 61.155. 
During the loading and unloading of affected waste, asbestos warning 
signs must be affixed to the vehicles.

                        B. Waste Shipment Record

    4.B.1. For each load of asbestos waste that is regulated under the 
NESHAP, a waste shipment record (WSR) must be maintained in accordance 
with Sec. 61.150(d). Information that must be maintained for each waste 
load includes the following:
     Name, address, and telephone number of the waste generator
     Name and address of the local, State, or EPA regional 
office responsible for administering the asbestos NESHAP program
     Quantity of waste in cubic meters (or cubic yards)
     Name and telephone number of the disposal site operator
     Name and physical site location of the disposal site
     Date transported
     Name, address, and telephone number of the transporter(s)
     Certification that the contents meet all government 
regulations for transport by highways.

[[Page 112]]

    4.B.2. The waste generator is responsible for ensuring that a copy 
of the WSR is delivered to the disposal site along with the waste 
shipment. If a copy of the WSR signed by the disposal site operator is 
not returned to the waste generator within 35 days, the waste generator 
must contact the transporter and/or the disposal site to determine the 
status of the waste shipment. 40 CFR 61.150(d)(3). If the signed WSR is 
not received within 45 days, the waste generator must report, in 
writing, to the responsible NESHAP program agency and send along a copy 
of the WSR. 40 CFR 61.150(d)(4). Copies of WSRs, including those signed 
by the disposal site operator, must be retained for at least 2 years. 40 
CFR 61.150(d)(5).

                               V. Training

    5.1. For those roof removals that are subject to the NESHAP, at 
least one on-site supervisor trained in the provisions of the NESHAP 
must be present during the removal of the asbestos roofing material. 40 
CFR 61.145(c)(8). In EPA's view, this person can be a job foreman, a 
hired consultant, or someone who can represent the building owner or 
contractor responsible for the removal. In addition to the initial 
training requirement, a refresher training course is required every 2 
years. The NESHAP training requirements became effective on November 20, 
1991.
    5.2. Asbestos training courses developed specifically to address 
compliance with the NESHAP in roofing work, as well as courses developed 
for other purposes can satisfy this requirement of the NESHAP, as long 
as the course covers the areas specified in the regulation. EPA believes 
that Asbestos Hazard Emergency Response Act (AHERA) training courses 
will, for example, satisfy the NESHAP training requirements. However, 
nothing in this interpretive rule or in the NESHAP shall be deemed to 
require that roofing contractors or roofing workers performing 
operations covered by the NESHAP must be trained or accredited under 
AHERA, as amended by the Asbestos School Hazard Abatement 
Reauthorization Act (ASHARA). Likewise, state or local authorities may 
independently impose additional training, licensing, or accreditation 
requirements on roofing contractors performing operations covered by the 
NESHAP, but such additional training, licensing or accreditation is not 
called for by this interpretive rule or the federal NESHAP.
    5.3. For removal of Category I asbestos containing roofing material 
where RB roof cutters or equipment that similarly damages the asbestos-
containing roofing material are used, the NESHAP training requirements 
(Sec. 61.145(c)(8)) apply as discussed in Section I above. It is EPA's 
intention that removal of Category I asbestos-containing roofing 
material using hatchets, axes, knives, and/or the use of spud bars, pry 
bars and shovels to lift the roofing material, or similar removal 
methods that slice, punch, or shear the roof membrane are not subject to 
the training requirements, since these methods do not cause the roof 
removal to be subject to the NESHAP. Likewise, it is EPA's intention 
that roof removal operations involving Category II nonfriable ACM are 
not subject to the training requirements where such operations are not 
subject to the NESHAP as discussed in section I above.

 Subpart N--National Emission Standard for Inorganic Arsenic Emissions 
                     From Glass Manufacturing Plants

    Source: 51 FR 28025, Aug. 4, 1986, unless otherwise noted.



Sec. 61.160  Applicability and designation of source.

    (a) The source to which this subpart applies is each glass melting 
furnace that uses commercial arsenic as a raw material. This subpart 
does not apply to pot furnaces.
    (b) Rebricking is not considered construction or modification for 
the purposes of Sec. 61.05(a).



Sec. 61.161  Definitions.

    The terms used in this subpart are defined in the Clean Air Act, in 
Sec. 61.02, or in this section as follows:
    Arsenic-containing glass type means any glass that is distinguished 
from other glass solely by the weight percent of arsenic added as a raw 
material and by the weight percent of arsenic in the glass produced. Any 
two or more glasses that have the same weight percent of arsenic in the 
raw materials as well as in the glass produced shall be considered to 
belong to one arsenic-containing glass type, without regard to the 
recipe used or any other characteristics of the glass or the method of 
production.
    By-pass the control device means to operate the glass melting 
furnace without operating the control device to which that furnace's 
emissions are directed routinely.
    Commercial arsenic means any form of arsenic that is produced by 
extraction

[[Page 113]]

from any arsenic-containing substance and is intended for sale or for 
intentional use in a manufacturing process. Arsenic that is a naturally 
occurring trace constituent of another substance is not considered 
``commercial arsenic.''
    Cullet means waste glass recycled to a glass melting furnace.
    Glass melting furnace means a unit comprising a refractory vessel in 
which raw materials are charged, melted at high temperature, refined, 
and conditioned to produce molten glass. The unit includes foundations, 
superstructure and retaining walls, raw material charger systems, heat 
exchangers, melter cooling system, exhaust system, refractory brick 
work, fuel supply and electrical boosting equipment, integral control 
systems and instrumentation, and appendages for conditioning and 
distributing molten glass to forming apparatuses. The forming 
apparatuses, including the float bath used in flat glass manufacturing, 
are not considered part of the glass melting furnace.
    Glass produced means the glass pulled from the glass melting 
furnace.
    Inorganic arsenic means the oxides and other noncarbon compounds of 
the element arsenic included in particulate matter, vapors, and 
aerosols.
    Malfunction means any sudden failure of air pollution control 
equipment or process equipment or of a process to operate in a normal or 
usual manner so that emissions of arsenic are increased.
    Pot furnace means a glass melting furnace that contains one or more 
refractory vessels in which glass is melted by indirect heating. The 
openings of the vessels are in the outside wall of the furnace and are 
covered with refractory stoppers during melting.
    Rebricking means cold replacement of damaged or worn refractory 
parts of the glass melting furnace. Rebricking includes replacement of 
the refractories comprising the bottom, sidewalls, or roof of the 
melting vessel; replacement of refractory work in the heat exchanger; 
and replacement of refractory portions of the glass conditioning and 
distribution system.
    Shutdown means the cessation of operation of an affected source for 
any purpose.
    Theoretical arsenic emissions factor means the amount of inorganic 
arsenic, expressed in grams per kilogram of glass produced, as 
determined based on a material balance.
    Uncontrolled total arsenic emissions means the total inorganic 
arsenic in the glass melting furnace exhaust gas preceding any add-on 
emission control device.

[51 FR 28025, Aug. 4, 1986; 51 FR 35355, Oct. 3, 1986]



Sec. 61.162  Emission limits.

    (a) The owner or operator of an existing glass melting furnace 
subject to the provisions of this subpart shall comply with either 
paragraph (a)(1) or (a)(2) of this section; except as provided in 
paragraph (c) of this section.
    (1) Uncontrolled total arsenic emissions from the glass melting 
furnace shall be less than 2.5 Mg per year, or
    (2) Total arsenic emissions from the glass melting furnace shall be 
conveyed to a control device and reduced by at least 85 percent.
    (b) The owner or operator of a new or modified glass melting furnace 
subject to the provisions of this subpart shall comply with either 
paragraph (b)(1) or (b)(2) of this section, except as provided in 
paragraph (c) of this section.
    (1) Uncontrolled total arsenic emissions from the glass melting 
furnace shall be less than 0.4 Mg per year, or
    (2) Total arsenic emissions from the glass melting furnace shall be 
conveyed to a control device and reduced by at least 85 percent.
    (c) An owner or operator of a source subject to the requirements of 
this section may, after approval by the Administrator, bypass the 
control device to which arsenic emissions from the furnace are directed 
for a limited period of time for designated purposes such as maintenance 
of the control device, as specified in Sec. 61.165(e).
    (d) At all times, including periods of startup, shutdown, and 
malfunction, the owner or operator of a glass melting furnace subject to 
the provisions of this subpart shall operate and maintain the furnace 
and associated air pollution control equipment in a manner consistent 
with good air pollution control practice for minimizing emissions of 
inorganic arsenic to the atmosphere

[[Page 114]]

to the maximum extent practicable. Determination of whether acceptable 
operating and maintenance procedures are being used will be based on 
information available to the Administrator, which may include, but is 
not limited to, monitoring results, review of operating and maintenance 
procedures, inspection of the source, and review of other records.



Sec. 61.163  Emission monitoring.

    (a) An owner or operator of a glass melting furnace subject to the 
emission limit in Sec. 61.162(a)(2) or Sec. 61.162(b)(2) shall:
    (1) Install, calibrate, maintain, and operate a continuous 
monitoring system for the measurement of the opacity of emissions 
discharged into the atmosphere from the control device; and
    (2) Install, calibrate, maintain, and operate a monitoring device 
for the continuous measurement of the temperature of the gas entering 
the control device.
    (b) All continuous monitoring systems and monitoring devices shall 
be installed and operational prior to performance of an emission test 
required by Sec. 61.164(a). Verification of operational status shall, at 
a minimum, consist of an evaluation of the monitoring system in 
accordance with the requirements and procedures contained in Performance 
Specification 1 of appendix B of 40 CFR part 60.
    (c) During the emission test required in Sec. 61.164(a) each owner 
or operator subject to paragraph (a) of this section shall:
    (1) Conduct continuous opacity monitoring from the beginning of the 
first test run until the completion of the third test run. Process and 
control equipment shall be operated in a manner that will minimize 
opacity of emissions, subject to the Administrator's approval.
    (2) Calculate 6-minute opacity averages from 24 or more data points 
equally spaced over each 6-minute period during the test runs.
    (3) Determine, based on the 6-minute opacity averages, the opacity 
value corresponding to the 99 percent upper confidence level of a normal 
or log-normal (whichever the owner or operator determines is more 
representative) distribution of the average opacity values.
    (4) Conduct continuous monitoring of the temperature of the gas 
entering the control device from the beginning of the first test run 
until completion of the third test run.
    (5) Calculate 15-minute averages of the temperature of the gas 
entering the control device during each test run.
    (d) An owner or operator may redetermine the values described in 
paragraph (c) of this section during any emission test that demonstrates 
compliance with the emission limits in Sec. 61.162(a)(2) or 
Sec. 61.162(b)(2).
    (e) The requirements of Sec. 60.13(d) and Sec. 60.13(f) shall apply 
to an owner or operator subject to paragraph (a) of this section.
    (f) Except for system breakdowns, repairs, calibration checks, and 
zero and span adjustments required under Sec. 60.13(d), all continuous 
monitoring systems shall be in continuous operation and shall meet 
minimum frequency of operation requirements by completing a minimum of 
one cycle of sampling and analyzing for each successive 10-second period 
and one cycle of data recording for each successive 6-minute period.
    (g) An owner or operator subject to paragraph (a) of this section 
shall:
    (1) Reduce all opacity data to 6-minute averages. Six-minute 
averages shall be calculated from 24 or more data points equally spaced 
over each 6-minute period. Data recorded during periods of monitoring 
system breakdowns, repairs, calibration checks, and zero and span 
adjustments shall not be included in the data averages calculated under 
this paragraph, and
    (2) Calculate 15-minute averages of the temperature of the gas 
entering the control device for each 15-minute operating period.
    (h) After receipt and consideration of written application, the 
Administrator may approve alternative monitoring systems for the 
measurement of one or more process or operating parameters that is or 
are demonstrated to enable accurate and representative monitoring of a 
properly operating control device. Upon approval of an alternative 
monitoring system for an affected source, the Administrator will specify

[[Page 115]]

requirements to replace the requirements of paragraphs (a)--(g) of this 
section for that system.

method with minor changes in methodology;
    (2) Approves the use of an equivalent method;
    (3) Approves the use of an alternative method the results of which 
he has determined to be adequate for indicating whether a specific 
source is in compliance; or
    (4) Waives the requirement for emission tests as provided under 
Sec. 61.13.
    (b) Unless a waiver of emission testing is obtained, the owner or 
operator shall conduct emission tests required by this section:

follows:
    (i) Copper converter. (A) Increase the air curtain and exhaust flow 
rates to their optimum conditions prior to raising the primary hood and 
rolling the copper converter out for charging, skimming, or pouring.
    (B) Once rolled out, prior to the commencement of skimming or 
pouring, hold the copper converter in an idle position until fuming from 
the molten bath has been minimized.
    (C) During skimming, raise the receiving ladle off the ground and 
position the ladle as close to the copper converter mouth as possible to 
minimize the drop distance between the converter mouth and the receiving 
ladle.
    (D) Control the rate of flow into the receiving ladle to the extent 
practicable to minimize fuming.
    (E) Upon the completion of each charge, withdraw the charging ladle 
or vessel used from the confines of the secondary hood in a slow, 
deliberate manner.
    (F) During charging, skimming, or pouring, ensure that the crane 
block does not disturb the air flow between the horizontal-slotted 
plenum and the exhaust hood.
    (ii) Secondary hood system. (A) Operate the secondary hood system 
under conditions that will result in the maximum capture of inorganic 
arsenic emissions.
    (B) Within 30 days after the effective date of this subpart, or

any

[[Page 121]]

change in the operating conditions submitted pursuant to the 
requirements of paragraph (b)(2)(ii)(B) that will result in any 
reduction in the maximum capture of inorganic arsenic emissions.
    (3) Comply with the following inspection and maintenance 
requirements after installing the secondary hood system required in 
paragraph (b)(1) of this section:
    (i) At least once every month, visually inspect the components of 
the secondary hood system that are exposed to potential damage from 
crane and ladle operation, including the hood enclosure, side- and back-
wall hood seals, and the horizontal slot.
    (ii) Replace or repair any defective or damaged components of the 
secondary hood system within 30 days after discovering the defective or 
damaged components.
    (c) No owner or operator of a copper converter subject to the 
provisions of this subpart shall cause or allow to be discharged into 
the atmosphere any copper converter secondary emissions that exit from a 
control device and contain particulate matter in excess of 11.6 
milligrams per dry standard cubic meter.
    (d) The owner or operator of a copper converter subject to the 
provisions of this subpart shall submit a description of a plan for 
control of inorganic arsenic emissions from the copper converter and 
associated air pollution control equipment. This plan shall be submitted 
within 90 days after the effective date of this subpart, unless a waiver 
of compliance is granted under Sec. 61.11. If a waiver of compliance is 
granted, the plan shall be submitted on a date set by the Administrator.

finds that:
    (1) It includes a systematic procedure for identifying malfunctions 
and for reporting them immediately to smelter supervisory personnel.
    (2) It specifies the procedures that will be followed to ensure that 
equipment or process breakdowns due entirely or in part to poor 
maintenance or other preventable conditions do not occur.
    (3) It specifies the measures that will be taken to ensure 
compliance with paragraph (b)(2) of this section.
    (e) The owner or operator shall implement the plan required under 
paragraph (d) of this section unless otherwise specified by the 
Administrator.
    (f) At all times, including periods of startup, shutdown, and 
malfunction, the owner or operator of a copper converter subject to the 
provisions of this subpart shall operate and maintain the converter and 
associated air pollution control equipment in a manner consistent with 
good air pollution control practice for minimizing emissions of 
inorganic arsenic to the atmosphere to the maximum extent practicable. 
Determination of whether acceptable operating and maintenance procedures 
are being used will be based on information available to the 
Administrator, which may include, but is not limited to, monitoring 
results, review of operating and maintenance procedures, inspection of 
the source, and review of other records.

shall assure that the stack does not emit more than 20 pCi/
m2-s of radon-222 into the air.



Sec. 61.203  Radon monitoring and compliance procedures.

    (a) Within sixty days following the date on which a stack becomes an 
inactive stack, or within ninety days after the date on which this 
subpart first took effect if a stack was already inactive on that date, 
each owner or operator of an inactive phosphogypsum stack shall test the 
stack for radon-222 flux in accordance with the procedures described in 
40 CFR part 61, appendix B, Method 115. EPA shall be notified at

[[Page 131]]

least 30 days prior to each such emissions test so that EPA may, at its 
option, observe the test. If meteorological conditions are such that a 
test cannot be properly conducted, then the owner or operator shall 
notify EPA and test as soon as conditions permit.
    (b)(1) Within ninety days after the testing is required, the owner 
or operator shall provide EPA with a report detailing the actions taken 
and the results of the radon-222 flux testing. Each report shall also 
include the following information:
    (i) The name and location of the facility;
    (ii) A list of the stacks at the facility including the size and 
dimensions of each stack;
    (iii) The name of the person responsible for the operation of the

personally examined and am familiar with the information submitted 
herein and based on may 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. See, 18 U.S.C. 1001.''
    (c) If the owner or operator of an inactive stack chooses to conduct 
measurements over a one year period as permitted by Method 115 in 
appendix B to part 61, within ninety days after the testing commences 
the owner or operator shall provide EPA with an initial report, 
including the results of the first measurement period and a schedule for 
all subsequent measurements. An additional report containing all the 
information in Sec. 61.203(b) shall be submitted within ninety days 
after completion of the final measurements.
    (d) If at any point an owner or operator of a stack once again uses 
an inactive stack for the disposal of phosphogypsum or for water 
management, the stack ceases to be in inactive status and the owner or 
operator must notify EPA in writing within 45 days. When the owner or 
operator ceases to use the stack for disposal of phosphogypsum or water 
management, the stack will once again become inactive and the owner or 
operator must satisfy again all testing and reporting requirements for 
inactive stacks.
    (e) If an owner or operator removes phosphogypsum from an inactive 
stack, the owner shall test the stack in accordance with the procedures 
described in 40 CFR part 61, appendix B, Method 115. The stack shall be 
tested within ninety days of the date that the owner or operator first 
removes phosphogypsum from the stack, and the test shall be repeated at 
least once during each calendar year that the owner or operator removes 
additional phosphogypsum from the stack. EPA shall be notified at least 
30 days prior to an emissions test so that EPA may, at its option, 
observe the test. If meteorological conditions are such that a test 
cannot be properly conducted, then the owner shall notify EPA and test 
as soon as conditions permit. Within ninety days after completion of a 
test, the owner or operator shall provide EPA with a report detailing 
the actions taken and the results of the radon-222 flux testing. Each 
such report shall include all of the information specified by

distribution of phosphogypsum removed from the location continues.
    (1) A minimum of 30 phosphogypsum samples shall be taken at 
regularly spaced intervals across the surface of the location on the 
stack from which the phosphogypsum will be removed. Let n1 
represent the number of samples taken.
    (2) Measure the radium-226 concentration of each of the 
n1 samples in accordance with the analytical procedures 
described in 40 CFR part 61, appendix B, Method 114.

[[Page 134]]

    (3) Calculate the mean, x1, and the standard deviation, 
s1, of the n1 radium-226 concentrations:
[GRAPHIC] [TIFF OMITTED] TR03FE99.054

Where x1 and s1 are expressed in pCi/g.

    (4) Calculate the 95th percentile for the distribution, 
x*, using the following equation:
[GRAPHIC] [TIFF OMITTED] TR03FE99.055

Where x* is expressed in pCi/g.

    (5) If the purpose for removing phosphogypsum from a stack is for 
distribution to commerce pursuant to Sec. 61.206, the owner or operator 
of a phosphogypsum stack shall report the mean, standard deviation, 95th 
percentile and sample size. If the purpose for removing phosphogypsum 
from a stack is for distribution to commerce pursuant to Sec. 61.204, 
the additional sampling procedures set forth in paragraphs (b) and (c) 
of this section shall apply.
    (b) Based on the values for x1 and x* 
calculated in paragraphs paragraphs (a)(3) and (4) of this section, 
determine which of the following conditions will be met:
    (1) If x1  10 pCi/g and x*  10 pCi/g; 
phosphogypsum may be removed from this area of the stack for 
distribution in commerce pursuant to Sec. 61.204.
    (2) If x1,  10 pCi/g and x* > 10 pCi/g, the owner or 
operator may elect to follow the procedures for further sampling set 
forth in paragraph (c) of this section:
    (3) If x1  10 pCi/g; phosphogypsum shall not 
be removed from this area of the stack for distribution in commerce 
pursuant to Sec. 61.204.
    (c) If the owner or operator elects to conduct further sampling to 
determine if phosphogypsum can be removed from this area of the stack, 
the following procedure shall apply. The objective of the following 
procedure is to demonstrate, with a 95% probability, that the 
phosphogypsum from this area of the stack has a radium-226 concentration 
no greater than 10 pCi/g. The procedure is iterative, the sample size 
may have to be increased more than one time; otherwise the phosphogypsum 
cannot be removed from this area of the stack for distribution to 
commerce pursuant to Sec. 61.204.
    (1)(i) Solve the following equation for the total number of samples 
required:
[GRAPHIC] [TIFF OMITTED] TR03FE99.056

    (ii) The sample size n2 shall be rounded upwards to the 
next whole number. The number of additional samples needed is 
nA = n2-n1.
    (2) Obtain the necessary number of additional samples, 
nA, which shall also be taken at regularly spaced intervals 
across the surface of the location on the stack from which phosphogypsum 
will be removed.
    (3) Measure the radium-226 concentration of each of the 
nA additional samples in accordance with the analytical 
procedures described in 40 CFR part 61, appendix B, Method 114.
    (4) Recalculate the mean and standard deviation of the entire set of 
n2 radium-226 concentrations by joining this set of 
nA concentrations with the n1 concentrations 
previously measured. Use the formulas in paragraph (a)(3) of this 
section, substituting the entire set of n2 samples in place 
of the n1 samples called for in paragraph (a)(3) of this 
section, thereby determining the mean, x2, and standard 
deviation, s2, for the entire set of n2 
concentrations.
    (5) Repeat the procedure described in paragraph (a)(4) of this 
section, substituting the recalculated mean, x2, for 
x1, the recalculated standard deviation, s2, for 
s1, and total sample size, n2, for n1.
    (6) Repeat the procedure described in paragraph (b) of this section, 
substituting the recalculated mean, x2 for x1.

Sec. 61.223  Compliance procedures.

    (a) Sixty days following the completion of covering the pile to 
limit radon emissions but prior to the long term stabilization of the 
pile, the owners or operators of uranium mill tailings shall conduct 
testing for all piles within the facility in accordance with the 
procedures described in 40 CFR part 61, appendix B, Method 115, or other 
procedures for which EPA has granted prior approval.
    (b) Ninety days after the testing is required, each facility shall 
provide EPA with a report detailing the actions taken and the results of 
the radon-222 flux testing. EPA shall be notified at least 30 days prior 
to an emission test so that EPA may, at its option, observe the test. If 
meteorological conditions are such that a test cannot be properly 
conducted, then the owner or operator shall notify EPA and test as soon 
as conditions permit. Each report shall also include the following 
information:
    (1) The name and location of the facility.
    (2) A list of the piles at the facility.
    (3) A description of the control measures taken to decrease the 
radon flux from the source and any actions taken to insure the long term 
effectiveness of the control measures.
    (4) The results of the testing conducted, including the results of 
each measurement.
    (5) Each report shall be signed and dated by a public official in 
charge of the facility and contain the following declaration immediately 
above the signature line:

    I certify under penalty of law that I have personally examined and 
am familiar with the information submitted herein and 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. See 18 U.S.C. 1001.

    (c) If year long measurements are made in accordance with Method 115 
of appendix B of part 61, this report shall include the results of the 
first measurement period and provide a schedule for the measurement 
frequency to be used. An additional report shall be submitted ninety 
days after completion of the final measurements.
    (d) If long term stabilization has begun before the effective date 
of the rule then testing may be conducted at any time, up to 60 days 
after the long term stabilization is completed.
    (e) If the testing demonstrates that the pile meets the requirement 
of Sec. 61.222(a) and long term stabilization has been completed then 
the pile is considered disposed for purposes of this rule.

Sec. 61.224  Recordkeeping requirements.

    The owner or operator must maintain records documenting the source 
of input parameters including the results of all measurements upon which 
they are based, the calculations and/or analytical methods used to 
derive values for input parameters, and the procedure used to determine 
compliance. This documentation should be sufficient to allow an 
independent auditor to verify the accuracy of the determination made 
concerning the facility's compliance with the standard. The 
Administrator shall be kept apprised of the location of these records 
and the records must be kept for at least five years and upon request be 
made available for inspection by the Administrator, or his authorized 
representative.

Sec. 61.226  Reconsideration of rescission and reinstatement of this subpart.

    (a) Reinstatement of this subpart upon completion of reconsideration 
of rescission. (1) The Administrator shall reinstate 40 CFR part 61, 
subpart T as applied to owners and operators of non-operational uranium 
mill tailings disposal sites that are licensed by the NRC or an affected 
Agreement State if the Administrator determines by rulemaking, based on 
the record, that NRC or an affected Agreement State has:
    (i) Failed on a programmatic basis to implement and enforce, in 
significant part, the regulations governing the disposal of uranium mill 
tailings promulgated by EPA and NRC or the tailings closure plan (radon) 
(i.e., contained in the license) requirements establishing milestones 
for the purpose of emplacing a permanent radon barrier that will achieve 
compliance with the 20 pCi/m \2\-s flux standard; and
    (ii) Those failures may reasonably be anticipated to significantly 
interfere (i.e., more than de minimis) with the timely emplacement of a 
permanent radon barrier constructed to achieve compliance with the 20 
pCi/m \2\-s flux standard at the uranium mill tailings disposal site.
    (2) The Administrator shall reinstate 40 CFR part 61, subpart T on a 
site-specific basis as applied to owners and operators of non-
operational uranium mill tailings disposal sites that are licensed by 
the NRC or an affected Agreement State if the Administrator determines 
by rulemaking, based on the record:
    (i) That NRC or an affected Agreement State has failed in 
significant part on a site-specific basis to achieve compliance by the 
operator of the site or sites with applicable license requirements, 
regulations, or standards implemented by NRC and the affected Agreement 
States; and
    (ii) Those failures may reasonably be anticipated to significantly 
interfere (i.e., more than de minimis) with the timely emplacement of a 
permanent radon barrier constructed to achieve compliance with the 20 
pCi/m \2\-s flux standard at the uranium mill tailings disposal site.
    (3) Upon completion of the reconsideration of rescission pursuant to 
Sec. 61.226(c) the Administrator may issue a finding that reinstatement 
of this subpart is not appropriate if the Administrator finds:
    (i) NRC and the affected Agreement States are on a programmatic 
basis implementing and enforcing, in significant part, the regulations 
governing the disposal of uranium mill tailings promulgated by EPA and 
NRC or the tailings closure plan (radon) (i.e., contained in the 
license) requirements establishing milestones for the purpose of 
emplacing a permanent radon barrier that will achieve compliance with 
the 20 pCi/m \2\-s flux standard; or
    (ii) NRC or an affected Agreement State are on a site-specific 
basis, in significant part, achieving compliance by the operator of the 
site or sites with applicable license requirements, regulations, or 
standards implemented by NRC and the affected Agreement States.
    (b) Procedures to petition for reconsideration of rescission of this 
subpart. (1) A person may petition the Administrator to reconsider the 
rescission and seek reinstatement of this subpart under Sec. 61.226(a).
    (2) EPA shall summarily dismiss a petition to reconsider rescission 
and seek reinstatement of this subpart under Sec. 61.226(a)(1) 
(programmatic basis), without prejudice, unless the petitioner 
demonstrates that written notice of the alleged failure(s) was provided 
to NRC at least 60 days before filing the petition with EPA. This 
notification shall include a statement of the grounds for such a 
petition and this notice requirement may be satisfied by, but is not 
limited to, submissions or pleadings submitted to NRC during a 
proceeding conducted by NRC.
    (3) EPA shall summarily dismiss a petition to reconsider rescission 
and seek reinstatement of this subpart under Sec. 61.226(a)(2) (site-
specific basis), without prejudice, unless the petitioner demonstrates 
that a written request was made to NRC or an affected Agreement State 
for enforcement or other relief at least 60 days before filing its 
petition with EPA, and unless the petitioner alleges that NRC or the 
affected Agreement State failed to respond to such request by taking 
action,

[[Page 139]]

as necessary, to assure timely implementation and enforcement of the 20 
pCi/m \2\-s flux standard.
    (4) Upon receipt of a petition under Sec. 61.226(b)(1) that is not 
dismissed under Sec. 61.226(b)(2) or (b)(3), EPA will propose to grant 
or deny an authorized petition to reconsider, take comments on the 
Agency's proposed action, and take final action granting or denying such 
petition to reconsider within 300 days of receipt.
    (c) Reconsideration of rescission of this subpart initiated by the 
Administrator. (1) The Administrator may initiate reconsideration of the 
rescission and reinstatement of this subpart as applied to owners and 
operators of non-operational uranium mill tailings disposal sites if EPA 
has reason to believe that NRC or an affected Agreement State has failed 
to implement and enforce, in significant part, the regulations governing 
the disposal of uranium mill tailings promulgated by EPA and NRC or the 
tailings closure plan (radon) requirements establishing milestones for 
the purpose of emplacing a permanent radon barrier that will achieve 
compliance with the 20 pCi/m \2\-s flux standard.
    (2) Before the Administrator initiates reconsideration of the 
rescission and reinstatement of this subpart under Sec. 61.226(c)(1), 
EPA shall consult with NRC to address EPA's concerns and if the 
consultation does not resolve the concerns, EPA shall provide NRC with 
60 days notice of the Agency's intent to initiate rulemaking to 
reinstate this subpart.

demonstrated emission reduction for the required work practices and will 
consider the commitment in paragraph (c)(4).
    (6) The Administrator may condition the permission on requirements 
that may be necessary to assure operation and maintenance to achieve the 
same emission reduction as the required work practices of this subpart.
    (d) An owner or operator may offer a unique approach to demonstrate 
the alternative means of emission limitation.
    (e)(1) Manufacturers of equipment used to control equipment leaks of

    (1) Monitoring shall comply with Method 21 of appendix A of 40 CFR 
part 60.
    (2) The detection instrument shall meet the performance criteria of 
Reference Method 21.
    (3) The instrument shall be calibrated before use on each day of its 
use by the procedures specified in Reference Method 21.
    (4) Calibration gases shall be:
    (i) Zero air (less than 10 ppm of hydrocarbon in air); and
    (ii) A mixture of methane or n-hexane and air at a concentration of 
approximately, but less than, 10,000 ppm methane or n-hexane.
    (5) The instrument probe shall be traversed around all potential 
leak interfaces as close to the interface as possible as described in 
Reference Method 21.
    (c) When equipment is tested for compliance with or monitored for no 
detectable emissions, the owner or operator shall comply with the 
following requirements:
    (1) The requirements of paragraphs (b) (1) through (4) shall apply.
    (2) The background level shall be determined, as set forth in 
Reference Method 21.
    (3) The instrument probe shall be traversed around all potential 
leak interfaces as close to the interface as possible as described in

    (d)(1) Each piece of equipment within a process unit that can 
conceivably contain equipment in VHAP service is presumed to be in VHAP 
service unless an owner or operator demonstrates that the piece of 
equipment is not in VHAP service. For a piece of equipment to be 
considered not in VHAP service, it must be determined that the percent 
VHAP content can be reasonably expected never to exceed 10 percent by 
weight. For purposes of determining the percent VHAP content of the 
process fluid that is contained in or contacts equipment, procedures 
that conform to the methods described in ASTM Method D-2267 
(incorporated by the reference as specified in Sec. 61.18) shall be 
used.
    (2)(i) An owner or operator may use engineering judgment rather than 
the procedures in paragraph (d)(1) of this section to demonstrate that 
the percent VHAP content does not exceed 10 percent by weight, provided 
that the engineering judgment demonstrates that the VHAP content clearly 
does not exceed 10 percent by weight. When an owner or operator and the 
Administrator do not agree on whether a piece of equipment is not in 
VHAP service, however, the procedures in paragraph (d)(1) of this 
section shall be used to resolve the disagreement.
    (ii) If an owner or operator determines that a piece of equipment is 
in

[[Page 148]]

VHAP service, the determination can be revised only after following the 
procedures in paragraph (d)(1) of this section.
    (3) Samples used in determining the percent VHAP content shall be 
representative of the process fluid that is contained in or contacts the 
equipment or the gas being combusted in the flare.
    (e)(1) Method 22 of appendix A of 40 CFR part 60 shall be used to 
determine compliance of flares with the visible emission provisions of 
this subpart.
    (2) The presence of a flare pilot flame shall be monitored using a 
thermocouple or any other equivalent device to detect the presence of a 
flame.
    (3) The net heating value of the gas being combusted in a flare 
shall be calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TC15NO91.055

Where:
HT=Net heating value of the sample, MJ/scm; where the net 
          enthalpy per mole of offgas is based on combustion at 25 deg. 
          C and 760 mm Hg, but the standard temperature for determining 
          the volume corresponding to one mole is 20 deg. C.
K=Constant, 1.74 x 10--7 (1/ppm) (g mole/scm) (MJ/kcal) where 
standard temperature for (g mole/scm) is 20 deg. C
Ci=Concentration of sample component i in ppm, as measured by 
Reference Method 18 of Appendix A of 40 FR part 60 and ASTM D2504-67 
(reapproved 1977) (incorporated by reference as specified in 
Sec. 61.18).
Hi=Net heat of combustion of sample component i, kcal/g mole. 
The heats of combustion may be determined using ASTM D2382-76 
(incorporated by reference as specified in Sec. 61.18) if published 
values are not available or cannot be calculated.

    (4) The actual exit velocity of a flare shall be determined by 
dividing the volumetric flowrate (in units of standard temperature and 
pressure), as determined by Reference Method 2, 2A, 2C, or 2D, as 
appropriate, by the unobstructed (free) cross section area of the flare 
tip.
    (5) The maximum permitted velocity, Vmax, for air-
assisted flares shall be determined by the following equation:

VMax=8.76+0.7084(HT)

Where:
VMax=Maximum permitted velocity, m/sec
8.706=Constant.
0.7084=Constant.
HT=The net heating value as determined in paragraph (e)(3) of 
this section.

    Subpart W--National Emission Standards for Radon Emissions From 
                         Operating Mill Tailings

    Source: 54 FR 51703, Dec. 15, 1989, unless otherwise noted.



Sec. 61.250  Designation of facilities.

    The provisions of this subpart apply to owners or operators of 
facilities licensed to manage uranium byproduct materials during and 
following the processing of uranium ores, commonly referred to as 
uranium mills and their associated tailings. This subpart does not apply 
to the disposal of tailings.



Sec. 61.251  Definitions.

    As used in this subpart, all terms not defined here have the meaning 
given them in the Clean Air Act or 40 CFR part 61, subpart A. The 
following terms shall have the following specific meanings:
    (a) Area means the vertical projection of the pile upon the earth's 
surface.
    (b) Continuous disposal means a method of tailings management and 
disposal in which tailings are dewatered by mechanical methods 
immediately after generation. The dried tailings are then placed in 
trenches or other disposal areas and immediately covered to limit 
emissions consistent with applicable Federal standards.
    (c) Dewatered means to remove the water from recently produced 
tailings by mechanical or evaporative methods such that the water 
content of the tailings does not exceed 30 percent by weight.
    (d) Existing impoundment means any uranium mill tailings impoundment 
which is licensed to accept additional tailings and is in existence as 
of December 15, 1989.
    (e) Operation means that an impoundment is being used for the 
continued placement of new tailings or is in standby status for such 
placement. An impoundment is in operation from the day that tailings are 
first placed in the impoundment until the day that final closure begins.
    (f) Phased disposal means a method of tailings management and 
disposal which uses lined impoundments which are filled and then 
immediately dried and covered to meet all applicable Federal standards.
    (g) Uranium byproduct material or tailings means the waste produced 
by the extraction or concentration of uranium from any ore processed 
primarily for its source material content. Ore bodies depleted by 
uranium solution extraction and which remain underground do not 
constitute byproduct material for the purposes of this subpart.



Sec. 61.252  Standard.

    (a) Radon-222 emissions to the ambient air from an existing uranium 
mill tailings pile shall not exceed 20 pCi/m2-s of radon-222.
    (b) After December 15, 1989, no new tailings impoundment can be 
built unless it is designed, constructed and operated to meet one of the 
two following work practices:
    (1) Phased disposal in lined tailings impoundments that are no more 
than 40 acres in area and meet the requirements of 40 CFR 192.32(a) as 
determined by the Nuclear Regulatory Commission. The owner or operator 
shall have no more than two impoundments, including existing 
impoundments, in operation at any one time.
    (2) Continuous disposal of tailings such that tailings are dewatered 
and immediately disposed with no more than 10 acres uncovered at any 
time and operated in accordance with Sec. 192.32(a) as determined by the 
Nuclear Regulatory Commission.
    (c) All mill owners or operators shall comply with the provisions of 
40 CFR 192.32(a) in the operation of tailings piles, the exemption for 
existing piles in 40 CFR 192.32(a) notwithstanding.



Sec. 61.253  Determining compliance.

    Compliance with the emission standard in this subpart shall be 
determined annually through the use of Method 115 of appendix B. When 
measurements are to be made over a one year period, EPA shall be 
provided with a schedule of the

[[Page 152]]

measurement frequency to be used. The schedule may be submitted to EPA 
prior to or after the first measurement period. EPA shall be notified 30 
days prior to any emissions test so that EPA may, at its option, observe 
the test.



Sec. 61.254  Annual reporting requirements.

    (a) The owners or operators of operating existing mill impoundments 
shall report the results of the compliance calculations required in 
Sec. 61.253 and the input parameters used in making the calculation for 
each calendar year shall be sent to EPA by March 31 of the following 
year. Each report shall also include the following information:
    (1) The name and location of the mill.
    (2) The name of the person responsible for the operation of the 
facility and the name of the person preparing the report (if different).

each measurement.
    (4) Each report shall be signed and dated by a corporate officer in 
charge of the facility and contain the following declaration immediately 
above the signature line: ``I certify under penalty of law that I have 
personally examined and am familiar with the information submitted 
herein and 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. See, 18 U.S.C. 1001.''
    (b) If the facility is not in compliance with the emission limits of 
Sec. 61.252 in the calendar year covered by the report, then the 
facility must commence reporting to the Administrator on a monthly basis 
the information listed in paragraph (a) of this section, for the 
preceding month. These reports will start the month immediately 
following the submittal of the annual report for the year in 
noncompliance and will be due 30 days following the end of each month. 
This increased level of reporting will continue until the Administrator 
has determined that the monthly reports are no longer necessary. In 
addition to all the information required in paragraph (a) of this 
section, monthly reports shall also include the following information:
    (1) All controls or other changes in operation of the facility that 
will be or are being installed to bring the facility into compliance.
    (2) If the facility is under a judicial or administrative 
enforcement decree, the report will describe the facilities performance 
under the terms of the decree.
    (c) The first report will cover the emissions of calendar year 1990.



Sec. 61.255  Recordkeeping requirements.

    The owner or operator of the mill must maintain records documenting 
the source of input parameters including the results of all measurements 
upon which they are based, the calculations and/or analytical methods 
used to derive values for input parameters, and the procedure used to 
determine compliance. In addition, the documentation should be 
sufficient to allow an independent auditor to verify the accuracy of the 
determination made concerning the facility's compliance with the 
standard. These records must be kept at the mill for at least five years 
and upon request be made available for inspection by the Administrator, 
or his authorized representative.



Sec. 61.256  Exemption from the reporting and testing requirements of 40 CFR 61.10.

    All facilities designated under this subpart are exempt from the 
reporting requirements of 40 CFR 61.10.

exempt from the provisions of this subpart.
    (c) This subpart does not apply to storage vessels used for storing 
benzene at coke by-product facilities.
    (d) This subpart does not apply to vessels permanently attached to 
motor vehicles such as trucks, rail cars, barges, or ships.
    (e) This subpart does not apply to pressure vessels designed to 
operate in excess of 204.9 kPa and without emissions to the atmosphere.
    (f) A designated source subject to the provisions of this subpart 
that is also subject to applicable provisions of 40 CFR part 60 subparts 
K, Ka, and Kb shall be required to comply only with the subpart that 
contains the most stringent requirements for that source.



Sec. 61.271  Emission standard.

    The owner or operator of each storage vessel with a design storage 
capacity greater than or equal to 38 cubic meters (10,000 gallons) to 
which this subpart applies shall comply with the requirements in 
paragraph (d) of this section and with the requirements either in 
paragraph (a), (b), or (c) of this section, or equivalent as provided in 
Sec. 61.273.
    (a) The storage vessel shall be equipped with a fixed roof and an 
internal floating roof.
    (1) An internal floating roof means a cover that rests on the liquid 
surface (but not necessarily in complete contact with it) inside a 
storage vessel that has a permanently affixed roof. The internal 
floating roof shall be floating on the liquid surface at all times, 
except during initial fill and during those intervals when the storage 
vessel is completely emptied or subsequently emptied and refilled. When 
the roof is resting on the leg supports, the process of filling, 
emptying, or refilling shall be continuous and shall be accomplished as 
rapidly as possible.
    (2) Each internal floating roof shall be equipped with one of the 
closure devices listed in paragraphs (a)(2) (i), (ii), or (iii) of this 
section between the wall of the storage vessel and the edge of the 
internal floating roof. This requirement does not apply to each existing 
storage vessel for which construction of an internal floating roof 
equipped with a continuous seal commenced on or before July 28, 1988. A 
continuous seal means a seal that forms a continuous closure that 
completely covers the space between the wall of the storage vessel and 
the edge of the internal floating roof.
    (i) A foam- or liquid-filled seal mounted in contact with the liquid 
(liquid-mounted seal). A liquid-mounted seal means a foam- or liquid-
filled seal mounted in contact with the liquid between the wall of the 
storage vessel and the floating roof continuously around the 
circumference of the vessel.
    (ii) Two seals mounted one above the other so that each forms a 
continuous closure that completely covers the space between the wall of 
the storage vessel and the edge of the internal floating roof. The lower 
seal may be vapor-mounted, but both must be continuous.
    (iii) A metallic shoe seal. A metallic shoe seal (also referred to 
as a mechanical shoe seal) is, but is not limited to, a metal sheet held 
vertically against the wall of the storage vessel by springs or weighted 
levers and is connected by braces to the floating roof. A flexible 
coated fabric (envelope) spans the annular space between the metal sheet 
and the floating roof.
    (3) Automatic bleeder vents are to be closed at all times when the 
roof is floating, except when the roof is being floated off or is being 
landed on the roof leg supports.
    (4) Each opening in a noncontact internal floating roof except for 
automatic bleeder vents (vacuum breaker vents) and the rim space vents 
is to provide a projection below the liquid surface.

[[Page 154]]

    (5) Each internal floating roof shall meet the specifications listed 
below. If an existing storage vessel had an internal floating roof with 
a continuous seal as of July 28, 1988, the requirements listed below do 
not have to be met until the first time after September 14, 1989, the 
vessel is emptied and degassed or September 14, 1999, whichever occurs 
first,
    (i) Each opening in the internal floating roof except for leg 
sleeves, automatic bleeder vents, rim space vents, column wells, ladder 
wells, sample wells, and stub drains is to be equipped with a cover or 
lid. The cover or lid shall be equipped with a gasket. Covers on each 
access hatch and automatic gauge float well shall be bolted.
    (ii) Each penetration of the internal floating roof for the purposes 
of sampling shall be a sample well. Each sample well shall have a slit 
fabric cover that covers at least 90 percent of the opening.
    (iii) Each automatic bleeder vent shall be gasketed.
    (iv) Rim space vents shall be equipped with a gasket.
    (v) Each penetration of the internal floating roof that allows for 
passage of a ladder shall have a gasketed sliding cover.
    (vi) Each penetration of the internal floating roof that allows for 
passage of a column supporting the fixed roof shall have a flexible 
fabric sleeve seal or a gasketed sliding cover.
    (6) Each cover or lid on any opening in the internal floating roof 
shall be closed (i.e., no visible gaps), except when a device is in 
actual use Covers on each access hatch and each automatic gauge float 
well which are equipped with bolts shall be bolted when they are not in 
use. Rim space vents are to be set to open only when the internal 
floating roof is not floating or at the manufacturer's recommended 
setting.
    (b) The storage vessel shall have an external floating roof.
    (1) An external floating roof means a pontoon-type or double-deck-
type cover that rests on the liquid surface in a vessel with no fixed 
roof.
    (2) Each external floating roof shall be equipped with a closure 
device between the wall of the storage vessel and the roof edge. Except 
as provided in paragraph (b)(5) of this section, the closure device is 
to consist of two seals, one above the other. The lower seal is referred 
to as the primary seal and the upper seal is referred to as the 
secondary seal.
    (i) The primary seal shall be either a metallic shoe seal or a 
liquid-mounted seal. A liquid-mounted seal means a foam- or liquid-
filled seal mounted in contact with the liquid between the wall of the 
storage vessel and the floating roof continuously around the 
circumference of the vessel. A metallic shoe seal (which can also be 
referred to as a mechanical shoe seal) is, but is not limited to, a 
metal sheet held vertically against the wall of the storage vessel by 
springs or weighted levers and is connected by braces to the floating 
roof. A flexible coated fabric (envelope) spans the annular space 
between the metal sheet and the floating roof. Except as provided in 
Sec. 61.272(b)(4), the primary seal shall completely cover the annular 
space between the edge of the floating roof and the vessel wall.
    (ii) The secondary seal shall completely cover the annular space 
between the external floating roof and the wall of the storage vessel in 
a continuous fashion except as allowed in Sec. 61.272(b)(4).
    (3) Except for automatic bleeder vents and rim space vents, each 
opening in the noncontact external floating roof shall provide a 
projection below the liquid surface. Except for automatic bleeder vents, 
rim space vents, roof drains, and leg sleeves, each opening in the roof 
is to be equipped with a gasketed cover, seal or lid which is to be 
maintained in a closed position at all times (i.e., no visible gap) 
except when the device is in actual use. Automatic bleeder vents are to 
be closed at all times when the roof is floating, except when the roof 
is being floated off or is being landed on the roof leg supports. Rim 
vents are to be set to open when the roof is being floated off the roof 
leg supports or at the manufacturer's recommended setting. Automatic 
bleeder vents and rim space vents are to be gasketed. Each emergency 
roof drain is to be provided with a slotted membrane fabric cover that 
covers at

[[Page 155]]

least 90 percent of the area of the opening.
    (4) The roof shall be floating on the liquid at all times (i.e., off 
the roof leg supports) except during initial fill until the roof is 
lifted off leg supports and when the vessel is completely emptied and 
subsequently refilled. The process of emptying and refilling when the 
roof is resting on the leg supports shall be continuous and shall be 
accomplished as rapidly as possible.
    (5) The requirement for a secondary seal does not apply to each 
existing storage vessel that was equipped with a liquid-mounted primary 
seal as of July 28, 1988, until after the first time after September 14, 
1989, when the vessel is emptied and degassed or 10 years from September 
14, 1989, whichever occurs first.
    (c) The storage vessel shall be equipped with a closed vent system 
and a control device.
    (1) The closed vent system shall be designed to collect all benzene 
vapors and gases discharged from the storage vessel and operated with no 
detectable emissions, as indicated by an instrument reading of less than 
500 ppm above background and visual inspections, as determined in 
Sec. 61.242-11 (subpart V).
    (2) The control device shall be designed and operated to reduce 
inlet benzene emissions by 95 percent or greater. If a flare is used as 
the control device, it shall meet the specifications described in the 
general control device requirements of 40 CFR 60.18.
    (3) The specifications and requirements listed in paragraphs (c)(1) 
and (c)(2) of this section for closed vent systems and control devices 
do not apply during periods of routine maintenance. During periods of 
routine maintenance, the benzene level in the storage vessel(s) serviced 
by the control device subject to the provisions of Sec. 61.271(c) may be 
lowered but not raised. Periods of routine maintenance shall not exceed 
72 hours as outlined in the maintenance plan required by 
Sec. 61.272(c)(1)(iii).
    (4) The specifications and requirements listed in paragraphs (c)(1) 
and (c)(2) of this section for closed vents and control devices do not 
apply during a control system malfunction. A control system malfunction 
means any sudden and unavoidable failure of air pollution control 
equipment. A failure caused entirely or in part by design deficiencies, 
poor maintenance, careless operation, or other preventable upset 
condition or equipment breakdown is not considered a malfunction.
    (d) The owner or operator of each affected storage vessel shall meet 
the requirements of paragraph (a), (b), or (c) of this section as 
follows:
    (1) The owner or operator of each existing benzene storage vessel 
shall meet the requirements of paragraph (a), (b), or (c) of this 
section no later than 90 days after September 14, 1989, with the 
exceptions noted in paragraphs (a)(5) and (b)(5), unless a waiver of 
compliance has been approved by the Administrator in accordance with 
Sec. 61.11.
    (2) The owner or operator of each benzene storage vessel upon which 
construction commenced after September 14, 1989, shall meet the 
requirements of paragraph (a), (b), or (c) of this section prior to 
filling (i.e., roof is lifted off leg supports) the storage vessel with 
benzene.
    (3) The owner or operator of each benzene storage vessel upon which 
construction commenced on or after July 28, 1988, and before September 
14, 1989, shall meet the requirements of paragraph (a), (b), or (c) of 
this section on September 14, 1989.

Sec. 61.272  Compliance provisions.

    (a) For each vessel complying with Sec. 61.271(a) (fixed roof and 
internal floating roof) each owner or operator shall:
    (1) After installing the control equipment required to comply with 
Sec. 61.271(a), visually inspect the internal floating roof, the primary 
seal, and the secondary seal (if one is in service), prior to filling 
the storage vessel with benzene. If there are holes, tears or other 
openings in the primary seal, the secondary seal, or the seal fabric, or 
defects in the internal floating roof, the owner or operator shall 
repair the items before filling the storage vessel.
    (2) Visually inspect the internal floating roof and the primary seal 
or the secondary seal (if one is in service)

[[Page 156]]

through manholes and roof hatches on the fixed roof at least once every 
12 months after initial fill, or at least once every 12 months after 
September 14, 1989, except as provided in paragraph (a)(4)(i) of this 
section. If the internal floating roof is not resting on the surface of 
the benzene liquid inside the storage vessel, or there is liquid on the 
roof, or the seal is detached, or there are holes or tears in the seal 
fabric, the owner or operator shall repair the items or empty and remove 
the storage vessel from service within 45 days. If a failure that is 
detected during inspections required in this paragraph cannot be 
repaired within 45 days and if the vessel cannot be emptied within 45 
days, an extension of up to 30 additional days may be requested from the 
Administrator in the inspection report required in Sec. 61.275(a). Such 
a request for an extension must document that alternate storage capacity 
is unavailable and specify a schedule of actions the company will take 
that will ensure that the control equipment will be repaired or the 
vessel will be emptied as soon as possible.
    (3) Visually inspect the internal floating roof, the primary seal, 
the secondary seal (if one is in service), gaskets, slotted membranes 
and sleeve seals (if any) each time the storage vessel is emptied and 
degassed. In no event shall inspections conducted in accordance with 
this provision occur at intervals greater than 10 years in the case of 
vessels conducting the annual visual inspections as specified in 
paragraph (a)(2) of this section and at intervals greater than 5 years 
in the case of vessels specified in paragraph (a)(4)(i) of this section.
    (i) For all the inspections required by paragraphs (a)(1) and (a)(3) 
of this section, the owner or operator shall notify the Administrator in 
writing at least 30 days prior to the refilling of each storage vessel 
to afford the Administrator the opportunity to have an observer present. 
If the inspection required by paragraph (a)(3) of this section is not 
planned and the owner or operator could not have known about the 
inspection 30 days in advance of refilling the vessel, the owner or 
operator shall notify the Administrator at least 7 days prior to the 
refilling of the storage vessel. Notification shall be made by telephone 
immediately followed by written documentation demonstrating why the 
inspection was unplanned. Alternatively, the notification including the 
written documentation may be made in writing and sent by express mail so 
that it is received by the Administrator at least 7 days prior to 
refilling.
    (ii) If the internal floating roof has defects, the primary seal has 
holes, tears, or other openings in the seal or the seal fabric, or the 
secondary seal has holes, tears, or other openings in the seal or the 
seal fabric, or the gaskets no longer close off the liquid surfaces from 
the atmosphere, or the slotted membrane has more than 10 percent open 
area, the owner or operator shall repair the items as necessary so that 
none of the conditions specified in this paragraph exist before 
refilling the storage vessel with benzene.
    (4) For vessels equipped with a double-seal system as specified in 
Sec. 61.271(a)(2)(ii):
    (i) Visually inspect the vessel as specified in paragraph (a)(3) of 
this section at least every 5 years; or
    (ii) Visually inspect the vessel annually as specified in paragraph 
(a)(2) of this section, and at least every 10 years as specified in 
paragraph (a)(3) of this section.
    (b) For each vessel complying with Sec. 61.271(b) (external floating 
roof) the owner or operator shall:
    (1) Determine the gap areas and maximum gap widths between the 
primary seal and the wall of the storage vessel, and the secondary seal 
and the wall of the storage vessel according to the following frequency.
    (i) For an external floating roof vessel equipped with primary and 
secondary seals, measurements of gaps between the vessel wall and the 
primary seal (seal gaps) shall be performed during the hydrostatic 
testing of the vessel or within 90 days of the initial fill with benzene 
or within 90 days of September 14, 1989, whichever occurs last, and at 
least once every 5 years thereafter, except as provided in paragraph 
(b)(1)(ii) of this section.
    (ii) For an external floating roof vessel equipped with a liquid-
mounted primary seal and without a secondary seal

[[Page 157]]

as provided for in Sec. 61.271(b)(5), measurement of gaps between the 
vessel wall and the primary seal (seal gaps) shall be performed within 
90 days of September 14, 1989, and at least once per year thereafter. 
When a secondary seal is installed over the primary seal, measurement of 
primary seal gaps shall be performed within 90 days of installation and 
at least once every 5 years thereafter.
    (iii) For an external floating roof vessel equipped with primary and 
secondary seals, measurements of gaps between the vessel wall and the 
secondary seal shall be performed within 90 days of the initial fill 
with benzene, within 90 days of installation of the secondary seal, or 
within 90 days after September 14, 1989, whichever occurs last, and at 
least once per year thereafter.
    (iv) If any source ceases to store benzene for a period of 1 year or 
more, subsequent introduction of benzene into the vessel shall be 
considered an initial fill for the purposes of paragraphs (b)(1)(i), 
(b)(1)(ii), and (b)(1)(iii) of this section.
    (2) Determine gap widths and areas in the primary and secondary 
seals individually by the following procedures:
    (i) Measure seal gaps, if any, at one or more floating roof levels 
when the roof is floating off the roof leg supports.
    (ii) Measure seal gaps around the entire circumference of the vessel 
in each place where a 0.32 centimeter (cm) (1/8 in) diameter uniform 
probe passes freely (without forcing or binding against the seal) 
between the seal and the wall of the storage vessel and measure the 
circumferential distance of each such location.
    (iii) The total surface area of each gap described in paragraph 
(b)(2)(ii) of this section shall be determined by using probes of 
various widths to measure accurately the actual distance from the vessel 
wall to the seal and multiplying each such width by its respective 
circumferential distance.
    (3) Add the gap surface area of each gap location for the primary 
seal and the secondary seal individually. Divide the sum for each seal 
by the nominal diameter of the vessel and compare each ratio to the 
respective standards in Sec. 61.272(b)(4) and Sec. 61.272(b)(5).
    (4) Repair conditions that do not meet requirements listed in 
paragraph (b)(4) (i) and (ii) within 45 days of identification in any 
inspection or empty and remove the storage vessel from service within 45 
days.
    (i) The accumulated area of gaps between the vessel wall and the 
metallic shoe seal or the liquid-mounted primary seal shall not exceed 
212 cm\2\ per meter of vessel diameter (10.0 in\2\ per foot of vessel 
diameter) and the width of any portion of any gap shall not exceed 3.81 
cm (1\1/2\ in).
    (A) One end of the metallic shoe is to extend into the stored liquid 
and the other end is to extend a minimum vertical distance of 61 cm (24 
in) above the stored liquid surface.
    (B) There are to be no holes, tears, or other openings in the shoe, 
seal fabric, or seal envelope.

    (A) The secondary seal is to be installed above the primary seal so 
that it completely covers the space between the roof edge and the vessel 
wall except as provided in paragraph (b)(4)(ii)(B) of this section.
    (B) The accumulated area of gaps between the vessel wall and the 
secondary seal shall not exceed 21.2 cm\2\ per meter of vessel diameter 
(1.0 in\2\ per foot of vessel diameter) or the width of any portion of 
any gap shall not exceed 1.27 cm (\1/2\ in). These seal gap requirements 
may be exceeded during the measurement of primary seal gaps as required 
by paragraph (b)(1)(i) or (b)(1)(ii) of this section.
    (C) There are to be no holes, tears, or other openings in the seal 
or seal fabric.
    (iii) If a failure that is detected during inspections required in 
this paragraph cannot be repaired within 45 days and if the vessel 
cannot be emptied within 45 days, an extension of up to 30 additional 
days may be requested from the Administrator in the inspection report 
required in Sec. 61.275(d). Such extension request must include a 
demonstration of unavailability of alternate storage capacity and a 
specification of a schedule that will assure

[[Page 158]]

that the control equipment will be repaired or the vessel will be 
emptied as soon as possible.
    (5) The owner or operator shall notify the Administrator 30 days in 
advance of any gap measurements required by paragraph (b)(1) of this 
section to afford the Administrator the opportunity to have an observer 
present.
    (6) Visually inspect the external floating roof, the primary seal, 
secondary seal, and fittings each time the vessel is emptied and 
degassed.
    (i) If the external floating roof has defects, the primary seal has 
holes, tears, or other openings in the seal or the seal fabric, or the 
secondary seal has holes, tears, or other openings in the seal or the 
seal fabric, the owner or operator shall repair the items as necessary 
so that none of the conditions specified in this paragraph exist before 
filling or refilling the storage vessel with benzene.
    (ii) For all the inspections required by paragraph (b)(6) of this 
section, the owner or operator shall notify the Administrator in writing 
at least 30 days prior to filling or refilling of each storage vessel to 
afford the Administrator the opportunity to inspect the storage vessel 
prior to refilling. If the inspection required by paragraph (b)(6) of 
this section is not planned and the owner or operator could not have 
known about the inspection 30 days in advance of refilling the vessel, 
the owner or operator shall notify the Administrator at least 7 days 
prior to refilling of the storage vessel. Notification shall be made by 
telephone immediately followed by written documentation demonstrating 
why the inspection was unplanned. Alternatively, this notification 
including the written documentation may be made in writing and sent by 
express mail so that it is received by the Administrator at least 7 days 
prior to the refilling.
    (c) The owner or operator of each source that is equipped with a 
closed vent system and control device as required in Sec. 60.271(c), 
other than a flare, shall meet the following requirements.
    (1) Within 90 days after initial fill or after September 14, 1989, 
whichever comes last, submit for approval by the Administrator, an 
operating plan containing the information listed below.
    (i) Documentation demonstrating that the control device being used 
achieves the required control efficiency during reasonably expected 
maximum loading conditions. This documentation is to include a 
description of the gas stream which enters the control device, including 
flow and benzene content under varying liquid level conditions (dynamic 
and static) and manufacturer's design specifications for the control 
device. If the control device or the closed vent capture system receives 
vapors, gases or liquids, other than fuels, from sources that are not 
designated sources under this subpart, the efficiency demonstration is 
to include consideration of all vapors, gases and liquids received by 
the closed vent capture system and control device. If an enclosed 
combustion device with a minimum residence time of 0.75 seconds and a 
minimum temperature of 816  deg.C is used to meet the 95 percent 
requirement, documentation that those conditions exist is sufficient to 
meet the requirements of this paragraph.
    (ii) A description of the parameter or parameters to be monitored to 
ensure that the control device is operated and maintained in conformance 
with its design and an explanation of the criteria used for selection of 
that parameter (or parameters).
    (iii) A maintenance plan for the system including the type of 
maintenance necessary, planned frequency of maintenance, and lengths of 
maintenance periods for those operations that would require the closed 
vent system or the control device to be out of compliance with 
Sec. 61.271(c). The maintenance plan shall require that the system be 
out of compliance with Sec. 61.271(c) for no more than 72 hours per 
year.
    (2) Operate, monitor the parameters, and maintain the closed vent 
system and control device in accordance with the operating plan 
submitted to the Administrator in accordance with paragraph (c)(1) of 
this section, unless the plan was modified by the Administrator during 
the approval process. In this case, the modified plan applies.
    (d) The owner or operator of each source that is equipped with a 
closed vent system and a flare to meet the requirements in 
Sec. 61.271(c) shall meet the

[[Page 159]]

requirements as specified in the general control device requirements in 
40 CFR 6O.18 (e) and (f).



Sec. 61.273  Alternative means of emission limitation.

    (a) Upon written application from any person, the Administrator may 
approve the use of alternative means of emission limitation which have 
been demonstrated to his satisfaction to achieve a reduction in benzene 
emissions at least equivalent to the reduction in emissions achieved by 
any requirement in Sec. 61.271 (a), (b), or (c) of this subpart.
    (b) Determination of equivalence to the reduction in emissions 
achieved by the requirements of Sec. 61.271 (a), (b), or (c) will be 
evaluated using the following information to be included in the written 
application to the Administrator:
    (1) Actual emissions tests that use full-size or scale-model storage 
vessels that accurately collect and measure all benzene emissions from a 
given control device, and that accurately simulate wind and account for 
other emission variables such as temperature and barometric pressure.
    (2) An engineering evaluation that the Administrator determines is 
an accurate method of determining equivalence.
    (c) The Administrator may condition approval of equivalency on 
requirements that may be necessary to ensure operation and maintenance 
to achieve the same emission reduction as the requirements of 
Sec. 61.271 (a), (b), or (c).
    (d) If, in the Administrator's judgment, an application for 
equivalence may be approvable, the Administrator will publish a notice 
of preliminary determination in the Federal Register and provide the 
opportunity for public hearing. After notice and opportunity for public 
hearing, the Administrator will determine the equivalence of the 
alternative means of emission limitation and will publish the final 
determination in the Federal Register.

railcar, the marine vessel loading racks shall be in compliance with the 
provisions of this subpart on and after July 23, 1991, while the tank 
truck loading racks and the railcar loading racks shall be in compliance 
as required by Sec. 61.12.

[55 FR 8341, Mar. 7, 1990, as amended at 55 FR 45804, Oct. 31, 1990]



Sec. 61.301  Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act, or in subpart A or subpart V of part 61.
    Bulk terminal means any facility which receives liquid product 
containing benzene by pipelines, marine vessels, tank trucks, or 
railcars, and loads the product for further distribution into tank 
trucks, railcars, or marine vessels.
    Car-sealed means having a seal that is placed on the device used to 
change the position of a valve (e.g., from open to closed) such that the 
position of the valve cannot be changed without breaking the seal and 
requiring the replacement of the old seal, once broken, with a new seal.
    Control device means all equipment used for recovering or oxidizing 
benzene vapors displaced from the affected facility.
    Incinerator means any enclosed combustion device that is used for 
destroying organic compounds and that does not extract energy in the 
form of steam or process heat. These devices do not rely on the heating 
value of the waste gas to sustain efficient combustion. Auxiliary fuel 
is burned in the device and the heat from the fuel flame heats the waste 
gas to combustion temperature. Temperature is controlled by controlling 
combustion air or fuel.
    Leak means any instrument reading of 10,000 ppmv or greater using 
method 21 of 40 CFR part 60, appendix A.
    Loading cycle means the time period from the beginning of filling a 
tank truck, railcar, or marine vessel until flow to the control device 
ceases, as measured by the flow indicator.
    Loading rack means the loading arms, pumps, meters, shutoff valves, 
relief valves, and other piping and valves necessary to fill tank 
trucks, railcars, or marine vessels.
    Marine vessel means any tank ship or tank barge which transports 
liquid product such as benzene.

[[Page 163]]

    Nonvapor tight means any tank truck, railcar, or marine vessel that 
does not pass the required vapor-tightness test.
    Process heater means a device that transfers heat liberated by 
burning fuel to fluids contained in tubes, except water that is heated 
to produce steam.
    Steam generating unit means any enclosed combustion device that uses 
fuel energy in the form of steam.
    Vapor collection system means any equipment located at the affected 
facility used for containing benzene vapors displaced during the loading 
of tank trucks, railcars, or marine vessels. This does not include the 
vapor collection system that is part of any tank truck, railcar, or 
marine vessel vapor collection manifold system.
    Vapor-tight marine vessel means a marine vessel with a benzene 
product tank that has been demonstrated within the preceding 12 months 
to have no leaks. This demonstration shall be made using method 21 of 
part 60, appendix A, during the last 20 percent of loading and during a 
period when the vessel is being loaded at its maximum loading rate. A 
reading of greater than 10,000 ppm as methane shall constitute a leak. 
As an alternative, a marine vessel owner or operator may use the vapor-
tightness test described in Sec. 61.304(f) to demonstrate vapor 
tightness. A marine vessel operated at negative pressure is assumed to 
be vapor-tight for the purpose of this standard.
    Vapor-tight tank truck or vapor-tight railcar means a tank truck or 
railcar for which it has been demonstrated within the preceding 12 
months that its product tank will sustain a pressure change of not more 
than 750 pascals within 5 minutes after it is pressurized to a minimum 
of 4,500 pascals. This capability is to be demonstrated using the 
pressure test procedure specified in method 27 of part 60, appendix A, 
and a pressure measurement device which has a precision of 
2.5 mm water and which is capable of measuring above the 
pressure at which the tank truck or railcar is to be tested for vapor 
tightness.



Sec. 61.302  Standards.

    (a) The owner or operator of an affected facility shall equip each 
loading rack with a vapor collection system that is:
    (1) Designed to collect all benzene vapors displaced from tank 
trucks, railcars, or marine vessels during loading, and
    (2) Designed to prevent any benzene vapors collected at one loading 
rack from passing through another loading rack to the atmosphere.
    (b) The owner or operator of an affected facility shall install a 
control device and reduce benzene emissions routed to the atmosphere 
through the control device by 98 weight percent. If a boiler or process 
heater is used to comply with the percent reduction requirement, then 
the vent stream shall be introduced into the flame zone of such a 
device.
    (c) The owner or operator of an affected facility shall operate any 
flare used to comply with paragraph (b) of this section in accordance 
with the requirements of Sec. 60.18 (b) through (f).
    (d) The owner or operator of an affected facility shall limit 
loading of benzene into vapor-tight tank trucks and vapor-tight railcars 
using the following procedures:
    (1) The owner or operator shall obtain the vapor-tightness 
documentation described in Sec. 61.305(h) for each tank truck or railcar 
loaded at the affected facility. The test date in the documentation must 
be within the preceding 12 months. The vapor-tightness test to be used 
for tank trucks and railcars is method 27 of part 60, appendix A.
    (2) The owner or operator shall cross-check the identification 
number for each tank truck or railcar to be loaded with the file of 
vapor-tightness documentation before the corresponding tank truck or 
railcar is loaded. If no documentation is on file, the owner or operator 
shall obtain a copy of the information from the tank truck or railcar 
operator before the tank truck or railcar is loaded.
    (3) Alternate procedures to those described in paragraphs (d)(1) and 
(d)(2) of this section may be used upon application to, and approval by, 
the Administrator.
    (e) The owner or operator of an affected facility shall limit the 
loading of marine vessels to those vessels that

[[Page 164]]

are vapor tight as determined by either paragraph (e)(1), (e)(2), 
(e)(3), or (e)(4) of this section.
    (1) The owner or operator of an affected facility shall ensure that 
each marine vessel is loaded with the benzene product tank below 
atmospheric pressure (i.e., at negative pressure). If the pressure is 
measured at the interface between the shoreside vapor collection pipe 
and the marine vessel vapor line, the pressure measured according to the 
procedures in Sec. 61.303(f) must be below atmospheric pressure.
    (2) The owner or operator of an affected facility shall use the 
following procedure to obtain the vapor-tightness documentation 
described in Sec. 61.305(h). The vapor-tightness test for marine vessels 
is method 21 of part 60, appendix A, and shall be applied to any 
potential sources of vapor leaks. A reading of 10,000 ppmv or greater as 
methane shall constitute a leak.
    (i) The owner or operator of an affected facility shall obtain the 
leak test documentation described in Sec. 61.305(h) for each marine 
vessel prior to loading, if available. The date of the test listed in

Sec. 61.342  Standards: General.

    (a) An owner or operator of a facility at which the total annual 
benzene quantity from facility waste is less than 10 megagrams per year 
(Mg/yr) shall be exempt from the requirements of paragraphs (b) and (c) 
of this section. The total annual benzene quantity from facility waste 
is the sum of the annual benzene quantity for each waste stream at the 
facility that has a flow-weighted annual average water content greater 
than 10 percent or that is mixed with water, or other wastes, at any 
time and the mixture has an annual average water content greater than 10 
percent. The benzene quantity in a waste stream is to be counted only 
once without multiple counting if other waste streams are mixed with or 
generated from the original waste stream. Other specific requirements 
for calculating the total annual benzene waste quantity are as follows:
    (1) Wastes that are exempted from control under Secs. 61.342(c)(2) 
and 61.342(c)(3) are included in the calculation of the total annual 
benzene quantity if they have an annual average water content greater 
than 10 percent, or if they are mixed with water or other wastes at any 
time and the mixture has an annual average water content greater than 10 
percent.
    (2) The benzene in a material subject to this subpart that is sold 
is included in the calculation of the total annual benzene quantity if 
the material has an annual average water content greater than 10 
percent.
    (3) Benzene in wastes generated by remediation activities conducted 
at the facility, such as the excavation of contaminated soil, pumping 
and treatment of groundwater, and the recovery of product from soil or 
groundwater, are not included in the calculation of total annual benzene 
quantity for that facility. If the facility's total annual benzene 
quantity is 10 Mg/yr or more, wastes generated by remediation activities 
are subject to the requirements of paragraphs (c) through (h) of this 
section. If the facility is managing remediation waste generated 
offsite, the benzene in this waste shall be included in the calculation 
of total annual benzene quantity in facility waste, if the waste streams 
have an annual average water content greater than 10 percent, or if they 
are mixed with water or other wastes at any time and the mixture has an 
annual average water content greater than 10 percent.
    (4) The total annual benzene quantity is determined based upon the 
quantity

[[Page 175]]

of benzene in the waste before any waste treatment occurs to remove the 
benzene except as specified in Sec. 61.355(c)(1)(i) (A) through (C).
    (b) Each owner or operator of a facility at which the total annual 
benzene quantity from facility waste is equal to or greater than 10 Mg/
yr as determined in paragraph (a) of this section shall be in compliance 
with the requirements of paragraphs (c) through (h) of this section no 
later than 90 days following the effective date, unless a waiver of 
compliance has been obtained under Sec. 61.11, or by the initial startup 
for a new source with an initial startup after the effective date.
    (1) The owner or operator of an existing source unable to comply 
with the rule within the required time may request a waiver of 
compliance under Sec. 61.10.
    (2) As part of the waiver application, the owner or operator shall 
submit to the Administrator a plan under Sec. 61.10(b)(3) that is an 
enforceable commitment to obtain environmental benefits to mitigate the 
benzene emissions that result from extending the compliance date. The 
plan shall include the following information:
    (i) A description of the method of compliance, including the control 
approach, schedule for installing controls, and quantity of the benzene 
emissions that result from extending the compliance date;
    (ii) If the control approach involves a compliance strategy designed 
to obtain integrated compliance with multiple regulatory requirements, a 
description of the other regulations involved and their effective dates; 
and
    (iii) A description of the actions to be taken at the facility to 
obtain mitigating environmental benefits, including how the benefits 
will be obtained, the schedule for these actions, and an estimate of the 
quantifiable benefits that directly result from these actions.
    (c) Each owner or operator of a facility at which the total annual 
benzene quantity from facility waste is equal to or greater than 10 Mg/
yr as determined in paragraph (a) of this section shall manage and treat 
the facility waste as follows:
    (1) For each waste stream that contains benzene, including (but not 
limited to) organic waste streams that contain less than 10 percent 
water and aqueous waste streams, even if the wastes are not discharged 
to an individual drain system, the owner or operator shall:
    (i) Remove or destroy the benzene contained in the waste using a 
treatment process or wastewater treatment system that complies with the 
standards specified in Sec. 61.348 of this subpart.
    (ii) Comply with the standards specified in Secs. 61.343 through 
61.347 of this subpart for each waste management unit that receives or 
manages the waste stream prior to and during treatment of the waste 
stream in accordance with paragraph (c)(1)(i) of this section.
    (iii) Each waste management unit used to manage or treat waste 
streams that will be recycled to a process shall comply with the 
standards specified in Secs. 61.343 through 61.347. Once the waste 
stream is recycled to a process, including to a tank used for the 
storage of production process feed, product, or product intermediates, 
unless this tank is used primarily for the storage of wastes, the 
material is no longer subject to paragraph (c) of this section.
    (2) A waste stream is exempt from paragraph (c)(1) of this section 
provided that the owner or operator demonstrates initially and, 
thereafter, at least once per year that the flow-weighted annual average 
benzene concentration for the waste stream is less than 10 ppmw as 
determined by the procedures specified in Sec. 61.355(c)(2) or 
Sec. 61.355(c)(3).
    (3) A waste stream is exempt from paragraph (c)(1) of this section 
provided that the owner or operator demonstrates initially and, 
thereafter, at least once per year that the conditions specified in 
either paragraph (c)(3)(i) or (c)(3)(ii) of this section are met.
    (i) The waste stream is process wastewater that has a flow rate less 
than 0.02 liters per minute or an annual wastewater quantity of less 
than 10 Mg/yr; or
    (ii) All of the following conditions are met:

for exemption in paragraph (c)(3)(ii) of this section does not exceed 
2.0 Mg/yr as determined in the procedures in Sec. 61.355(j), and
    (C) The total annual benzene quantity in a waste stream chosen for 
exemption, including process unit turnaround waste, is determined for 
the year in which the waste is generated.
    (d) As an alternative to the requirements specified in paragraphs 
(c) and (e) of this section, an owner or operator of a facility at which 
the total annual benzene quantity from facility waste is equal to or 
greater than 10 Mg/yr as determined in paragraph (a) of this section may 
elect to manage and treat the facility waste as follows:
    (1) The owner or operator shall manage and treat facility waste 
other than process wastewater in accordance with the requirements of 
paragraph (c)(1) of this section.

in accordance with the following requirements:
    (i) Process wastewater shall be treated to achieve a total annual 
benzene quantity from facility process wastewater less than 1 Mg/yr. 
Total annual benzene from facility process wastewater shall be 
determined by adding together the annual benzene quantity at the point 
of waste generation for each untreated process wastewater stream plus 
the annual benzene quantity exiting the treatment process for each 
process wastewater stream treated in accordance with the requirements of 
paragraph (c)(1)(i) of this section.
    (ii) Each treated process wastewater stream identified in paragraph 
(d)(2)(i) of this section shall be managed and treated in accordance

 Method 101--Determination of Particulate and Gaseous Mercury Emissions 
                  From Chlor-Alkali Plants--Air Streams

1. Applicability and Principle

    1.1  Applicability. This method applies to the determination of 
particulate and gaseous mercury (Hg) emissions from chlor-alkali plants 
and other sources (as specified in the regulations), where the carrier-
gas stream in the duct or stack is principally air.
    1.2  Principle. Particulate and gaseous Hg emissions are withdrawn 
isokinetically from the source and collected in acidic iodine 
monochloride (ICl) solution. The Hg collected (in the mercuric form) is 
reduced to elemental Hg, which is then aerated from the solution into an 
optical cell and measured by atomic absorption spectrophotometry.

2. Range and Sensitivity

    2.1  Range. After initial dilution, the range of this method is 0.5 
to 120 g Hg/ml. The upper limit can be extended by further 
dilution of the sample.
    2.2  Sensitivity. The sensitivity of this method depends on the 
recorder/spectrophotometer combination selected.

3. Interfering Agents

    3.1  Sampling. SO2 reduces ICl and causes premature 
depletion of the ICl solution.
    3.2  Analysis. ICl concentrations greater than 10-4molar 
inhibit the reduction of the Hg (II) ion in the aeration cell. 
Condensation of water vapor on the optical cell windows causes a 
positive interference.

4. Precision and Accuracy

    The following estimates are based on collaborative tests, wherein 13 
laboratories performed duplicate analyses on two Hg-containing samples 
from a chlor-alkali plant and on one laboratory-prepared sample of known 
Hg concentration. The concentration ranged from 2 to 65 g Hg/
ml.
    4.1  Precision. The estimated within-laboratory and between-
laboratory standard deviations are 1.6 and 1.8 g Hg/ml, 
respectively.
    4.2  Accuracy. The participating laboratories that analyzed a 64.3-
g Hg/ml (in 0.1 M ICl) standard obtained a mean of 63.7 
g Hg/ml.

5. Apparatus

Figure 101-1; it is similar to the Method 5 train (mention of Method 5 
refers to part 60 of 40 CFR). The sampling train consists of the 
following components:
    5.1.1  Probe Nozzle, Pitot Tube, Differential Pressure Gauge, 
Metering System, Barometer, and Gas Density Determination Equipment. 
Same as Method 5, Sections 2.1.1, 2.1.3, 2.1.4, 2.1.8, 2.1.9, and 
2.1.10, respectively.
    5.1.2  Probe Liner. Borosilicate or quartz glass tubing. The tester 
may use a heating system capable of maintaining a gas temperature of 
120plus-minus14  deg.C (248plus-minus25  deg.F) at 
the probe exit during sampling to prevent water condensation.
    Note: Do not use metal probe liners.
    5.1.3  Impingers. Four Greenburg-Smith impingers connected in series 
with leak-free ground glass fittings or any similar leak-free 
noncontaminating fittings. For the first, third, and fourth impingers, 
the tester may use impingers that are modified by replacing the tip with 
a 13-mm-ID (0.5-in.) glass tube extending to 13 mm (0.5 in.) from the 
bottom of the flask.
    5.1.4  Acid Trap. Mine Safety Appliances air line filter, Catalog 
number 81857, with acid absorbing cartridge and suitable connections, or

socket-connections are recommended) for all tubing connections between 
the solution cell and the optical cell; do not use Tygon tubing, other 
types of flexible tubing, or metal tubing as substitutes. The tester may 
use Teflon, steel, or copper tubing between the nitrogen tank and 
flowmetering valve (5.3.7), and Tygon, gum, or rubber tubing between the 
flowmetering valve and the aeration cell.
    5.3.11  Flow Rate Calibration Equipment. Bubble flowmeter or wet 
test meter for measuring a gas flow rate of 1.5plus-minus0.1

samples of the same aliquot size and concentration agree within 3 
percent of their average.
    5.4.2  A minimum of 95 percent of the spike is recovered when an 
aliquot of a source sample is spiked with a known concentration of 
mercury (II) compound.
    5.4.3  The reducing agent should be added after the aeration cell is 
closed.
    5.4.4  The aeration bottle bubbler should not contain a frit.
    5.4.5  Any Tygon used should be as short as possible and conditioned 
prior to use until blanks and standards yield linear and reproducible 
results.
    5.4.6  If manual stirring is done before aeration, it should be done 
with the aeration cell closed.
    5.4.7  A drying tube should not be used unless it is conditioned as 
the Tygon above.

6. Reagents

    Use ACS reagent-grade chemicals or equivalent, unless otherwise 
specified.
    6.1  Sampling and Recovery. The reagents used in sampling and 
recovery are as follows:
    6.1.1  Water. Deionized distilled, meeting ASTM Specifications for 
Type I Reagent Water--ASTM Test Method D1193-77 (incorporated by 
reference--see Sec. 61.18). If high concentrations of organic matter are 
not expected to be present, the analyst may eliminate the KMnO4 
test for oxidizable organic matter. Use this water in all dilutions and 
solution preparations.
    6.1.2  Nitric Acid (HNO3), 50 Percent (V/V). Mix equal 
volumes of concentrated HNO3 and deionized distilled water, 
being careful to slowly add the acid to the water.
    6.1.3  Silica Gel. Indicating type, 6- to 16-mesh. If previously 
used, dry at 175  deg.C (350  deg.F) for 2 hours. The tester may use new 
silica gel as received.
    6.1.4  Potassium Iodide (KI) Solution, 25 Percent. Dissolve 250 g of 
KI in deionized distilled water and dilute to 1 liter.
    6.1.5  Iodine Monochloride (ICl) Stock Solution, 1.0 M. To 800 ml of 
25 percent KI solution, add 800 ml of concentrated hydrochloric acid 
(HCl). Cool to room temperature. With vigorous stirring, slowly add 135 
g of potassium iodate (KIO3) and stir until all free iodine 
has dissolved. A clear orange-red solution occurs when all the KIO3 
has been added. Cool to room temperature and dilute to 1800 ml with 
deionized distilled water. Keep the solution in amber glass bottles to 
prevent degradation.
    6.1.6  Absorbing Solution, 0.1 M ICl. Dilute 100 ml of the 1.0 M ICl 
stock solution to 1 liter with deionized distilled water. Keep the 
solution in amber glass bottles and in darkness to prevent degradation. 
This reagent is stable for at least 2 months.
    6.2  Sample Preparation and Analysis. The reagents needed are listed 
below:
    6.2.1  Tin (II) Solution. Prepare fresh daily and keep sealed when 
not being used. Completely dissolve 20 g of tin (II) chloride [or 25 g 
of tin (II) sulfate] crystals (Baker Analyzed reagent grade or any other 
brand that will

[[Page 215]]

give a clear solution) in 25 ml of concentrated HCl. Dilute to 250 ml 
with deionized distilled water. Do not substitute HNO3, 
H2SO4, or other strong acids for the HCl.
    6.2.2  Mercury Stock Solution, 1 mg Hg/ml. Prepare and store all 
mercury standard solutions in borosilicate glass containers. Completely 
dissolve 0.1354 g of mercury (II) chloride in 75 ml of deionized 
distilled water in a 100 ml glass volumetric flask. Add 10 ml of 
concentrated HNO3, and adjust the volume to exactly 100 ml 
with deionized distilled water. Mix thoroughly. This solution is stable 
for at least 1 month.
    6.2.3  Sulfuric Acid, 5 Percent (V/V). Dilute 25 ml of concentrated 
H2SO4 to 500 ml with deionized distilled water.
    6.2.4  Intermediate Mercury Standard Solution, 10 g Hg/ml. 
Prepare fresh weekly. Pipet 5.0 ml of the mercury stock solution (6.2.2) 
into a 500-ml glass volumetric flask and add 20 ml of the 5 percent 
H2SO4 solution. Dilute to exactly 500 ml with 
deionized distilled water. Thoroughly mix the solution.
    6.2.5  Working Mercury Standard Solution, 200 ng Hg/ml. Prepare 
fresh daily. Pipet 5.0 ml from the ``Intermediate Mercury Standard 
Solution'' (6.2.4) into a 250-ml volumetric glass flask. Add 10 ml of 
the 5 percent H2SO4 and 2 ml of the 0.1 M ICl 
absorbing solution taken as a blank (7.2.3) and dilute to 250 ml with 
deionized distilled water. Mix thoroughly.

7. Procedure

    7.1  Sampling. Because of the complexity of this method, testers 
should be trained and experienced with the test procedures to assure 
reliable results. Since the amount of Hg that is collected generally is 
small, the method must be carefully applied to prevent contamination or 
loss of sample.
    7.1.1  Pretest Preparation. Follow the general procedure given in 
Method 5, Section 4.1.1, except omit the directions on the filter.
    7.1.2  Preliminary Determinations. Follow the general procedure 
given in Method 5, Section 4.1.2, except as follows: Select a nozzle 
size based on the range of velocity heads to assure that it is not 
necessary to change the nozzle size in order to maintain isokinetic 
sampling rates below 28 liters/min (1.0 cfm).
    Obtain samples over a period or periods that accurately determine 
the maximum emissions that occur in a 24-hour period. In the case of 
cyclic operations, run sufficient tests for the accurate determination 
of the emissions that occur over the duration of the cycle. A minimum 
sample time of 2 hours is recommended. In some instances, high Hg or 
high SO2 concentrations make it impossible to sample for the 
desired minimum time. This is indicated by reddening (liberation of free 
iodine) in the first impinger. In these cases, the tester may divide the 
sample run into two or more subruns to insure that the absorbing 
solution is not depleted.
    7.1.3  Preparation of Sampling Train. Clean all glassware [probe, 
impingers, and connectors] by rinsing with 50 percent HNO3, 
tap water, 0.1 M ICl, tap water, and finally deionized distilled water. 
Place 100 ml of 0.1 M ICl in each of the first three impingers. Take 
care to prevent the absorbing solution from contacting any greased 
surfaces. Place approximately 200 g of preweighed silica gel in the 
fourth impinger. The tester may use more silica gel, but should be 
careful to ensure that it is not entrained and carried out from the 
impinger during sampling. Place the silica gel container in a clean 
place for later use in the sample recovery. Alternatively, determine and 
record the weight of the silica gel plus impinger to the nearest 0.5 g.
    Install the selected nozzle using a Viton A O-ring when stack 
temperatures are less than 260  deg.C (500  deg.F). Use a fiberglass 
string gasket if temperatures are higher. See APTD-0576 (Citation 9 in 
Section 10) for details. Other connecting systems using either 316 
stainless steel or Teflon ferrules may be used. Mark the probe with 
heat-resistant tape or by some other method to denote the proper 
distance into the stack or duct for each sampling point. Assemble the 
train as shown in Figure 101-1, using (if necessary) a very light coat 
of silicone grease on all ground glass joints. Grease only the outer 
portion (see APTD-0576) to avoid possibility of contamination by the 
silicone grease.
    Note: An empty impinger may be inserted between the third impinger 
and the silica gel to remove excess moisture from the sample stream.
    After the sampling train has been assembled, turn on and set the 
probe, if applicable, at the desired operating temperature. Allow time 
for the temperatures to stabilize. Place crushed ice around the 
impingers.
    7.1.4  Leak-Check Procedures. Follow the leak-check procedures 
outlined in Method 5, Sections 4.1.4.1 (Pretest Leak Check), 4.1.4.2 
(Leak Checks During Sample Run), and 4.1.4.3 (Post-Test Leak Check).
    7.1.5  Mercury Train Operation. Follow the general procedure given 
in Method 5, Section 4.1.5. For each run, record the data required on a 
data sheet such as the one shown in Figure 101-4.
    7.1.6  Calculation of Percent Isokinetic. Same as Method 5, Section 
4.1.6.
    7.2  Sample Recovery. Begin proper cleanup procedure as soon as the 
probe is removed from the stack at the end of the sampling period.
    Allow the probe to cool. When it can be safely handled, wipe off any 
external particulate matter near the tip of the probe nozzle and place a 
cap over it. Do not cap off the probe tip tightly while the sampling 
train is

[[Page 216]]

cooling. Capping would create a vacuum and draw liquid out from the 
impingers.
    Before moving the sampling train to the cleanup site, remove the 
probe from the train, wipe off the silicone grease, and cap the open 
outlet of the probe. Be careful not to lose any condensate that might be 
present. Wipe off the silicone grease from the impinger. Use either 
ground-glass stoppers, plastic caps, or serum caps to close these 
openings.
    Transfer the probe and impinger assembly to a cleanup area that is 
clean, protected from the wind, and free of Hg contamination. The 
ambient air in laboratories located in the immediate vicinity of Hg-
using facilities is not normally free of Hg contamination.
    Inspect the train before and during assembly, and note any abnormal 
conditions. Treat the sample as follows:
    7.2.1  Container No. 1 (Impinger and Probe). Using a graduated 
cylinder, measure the liquid in the first three impingers to within 
plus-minus1 ml. Record the volume of liquid present (e.g., 
see Figure 5-3 of Method 5). This information is needed to calculate the 
moisture content of the effluent gas. (Use only glass storage bottles 
and graduated cylinders that have been precleaned as in Section 7.1.3.) 
Place the contents of the first three impingers into a 1000-ml glass 
sample bottle.
    Taking care that dust on the outside of the probe or other exterior 
surfaces does not get into the sample, quantitatively recover the Hg 
(and any condensate) from the probe nozzle, probe fitting, and probe 
liner as follows: Rinse these components with two 50-ml portions of 0.1 
M IC1. Next, rinse the probe nozzle, fitting and liner, and each piece 
of connecting glassware between the probe liner and the back half of the 
third impinger with a maximum of 400 ml of deionized distilled water. 
Add all washings to the 1000-ml glass sample bottle containing the 
liquid from the first three impingers.
    After all washings have been collected in the sample container, 
tighten the lid on the container to prevent leakage during shipment to 
the laboratory. Mark the height of the liquid to determine later whether 
leakage occurred during transport. Label the container to clearly 
identify its contents.
    7.2.2  Container No. 2 (Silica Gel). Note the color of the 
indicating silica gel to determine whether it has been completely spent 
and make a notation of its condition. Transfer the silica gel from its 
impinger to its original container and seal. The tester may use as aids 
a funnel to pour the silica gel and a rubber policeman to remove the 
silica gel from the impinger. The small amount of particles that may 
adhere to the impinger wall need not be removed. Since the gain in 
weight is to be used for moisture calculations, do not use any water or 
other liquids to transfer the silica gel. If a balance is available in 
the field, weigh the spent silica gel (or silica gel plus impinger) to 
the nearest 0.5 g; record this weight.
    7.2.3  Container No. 3 (Absorbing Solution Blank). For a blank, 
place 50 ml of the 0.1 M IC1 absorbing solution in a 100-ml sample 
bottle. Seal the container. Use this blank to prepare the working 
mercury standard solution (6.2.5).
    7.3  Sample Preparation. Check the liquid level in each container to 
see whether liquid was lost during transport. If a noticeable amount of 
leakage occurred, either void the sample or use methods subject to the 
approval of the Administrator to account for the losses. Then follow the 
procedures below:
    7.3.1  Container No. 1 (Impinger and Probe). Carefully transfer the 
contents of Container No. 1 into a 1000-ml volumetric flask and adjust 
the volume to exactly 1000 ml with deionized distilled water.
    7.3.2  Dilutions. Pipet a 2-ml aliquot from the diluted sample from 
7.3.1 into a 250-ml volumetric flask. Add 10 ml of 5 percent H2 
SO4 and adjust the volume to exactly 250 ml with deionized 
distilled water. These solutions are stable for at least 72 hours.
    Note: The dilution factor will be 250/2 for this solution.
    7.4  Analysis. Calibrate the spectrophotometer and recorder and 
prepare the calibration curve as described in Sections 8.1 to 8.2.
    7.4.1  Mercury Samples. Repeat the procedure used to establish the 
calibration curve with appropriately sized aliquots (1 to 5 ml) of each 
of the diluted samples (from Section 7.3.2) until two consecutive peak 
heights agree within plus-minus3 percent of their average 
value. The peak maximum of an aliquot (except the 5-ml aliquot) must be 
greater than 10 percent of the recorder full scale. If the peak maximum 
of a 1.0-ml aliquot is off scale on the recorder, further dilute the 
original source sample to bring the Hg concentration into the 
calibration range of the spectrophotometer.
    Run a blank and standard at least after every five samples to check 
the spectrophotometer calibration; recalibrate as necessary.
    It is also recommended that at least one sample from each stack test 
be checked by the Method of Standard Additions to confirm that matrix 
effects have not interfered in the analysis.
    7.4.2  Container No. 2 (Silica Gel). Weigh the spent silica gel (or 
silica gel plus impinger) to the nearest 0.5 g using a balance. (This 
step may be conducted in the field.)

8. Calibration and Standards

    Before use, clean all glassware, both new and used, as follows: 
brush with soap and water, liberally rinse with tap water, soak for 1 
hour in 50 percent HNO3, and then rinse with deionized 
distilled water.

[[Page 217]]

    8.1  Flow Calibration. Assemble the aeration system as shown in 
Figure 101-5. Set the outlet pressure on the aeration gas cylinder 
regulator to a minimum pressure of 500 mm Hg (10 psi), and use the 
flowmetering valve and a bubble flowmeter or wet test meter to obtain a 
flow rate of 1.5plus-minus0.1 liters/min through the aeration 
cell. After the flow calibration is complete, remove the bubble 
flowmeter from the system.
    8.2  Optical Cell Heating System Calibration. Using a 50-ml 
graduated cylinder, add 50 ml of deionized distilled water to the bottle 
section of the aeration cell and attach the bottle section to the 
bubbler section of the cell. Attach the aeration cell to the optical 
cell; and while aerating at 1.5 liters/min, determine the minimum 
variable transformer setting necessary to prevent condensation of 
moisture in the optical cell and in the connecting tubing. (This setting 
should not exceed 20 volts.)
    8.3  Spectrophotometer and Recorder Calibration. The mercury 
response may be measured by either peak height or peak area.
    Note: The temperature of the solution affects the rate at which 
elemental Hg is released from a solution and, consequently, it affects 
the shape of the absorption curve (area) and the point of maximum 
absorbance (peak height). Therefore, to obtain reproducible results, 
bring all solutions to room temperature before use.
    Set the spectrophotometer wavelength at 253.7 nm, and make certain 
the optical cell is at the minimum temperature that will prevent water 
condensation. Then set the recorder scale as follows: Using a 50-ml 
graduated cylinder, add 50 ml of deionized distilled water to the 
aeration cell bottle and pipet 5.0 ml of the working mercury standard 
solution into the aeration cell.
    Note: Always add the Hg-containing solution to the aeration cell 
after the 50 ml of deionized distilled water.
    Place a Teflon-coated stirring bar in the bottle. Before attaching 
the bottle section to the bubbler section of the aeration cell, make 
certain that (1) the aeration cell exit arm stopcock (Figure 101-3) is 
closed (so that Hg will not prematurely enter the optical cell when the 
reducing agent is being added) and (2) there is no flow through the 
bubbler. If conditions (1) and (2) are met, attach the bottle section to 
the bubbler section of the aeration cell. Pipet 5 ml of stannous 
chloride solution into the aeration cell through the side arm, and 
immediately stopper the side arm. Stir the solution for 15 sec, turn on 
the recorder, open the aeration cell exit arm stopcock, and then 
immediately initiate aeration with continued stirring. Determine the 
maximum absorbance of the standard and set this value to read 90 percent 
of the recorder full scale.
    8.4  Calibration Curve. After setting the recorder scale, repeat the 
procedure in Section 8.3 using 0.0-, 1.0-, 2.0-, 3.0-, 4.0-, and 5.0-ml 
aliquots of the working standard solution (final amount of Hg in the 
aeration cell is 0, 200, 400, 600, 800, and 1000 ng, respectively). 
Repeat this procedure on each aliquot size until two consecutive peaks 
agree within 3 percent of their average value. (Note: To prevent Hg 
carryover from one sample to another, do not close the aeration gas tank 
valve and do not disconnect the aeration cell from the optical cell 
until the recorder pen has returned to the baseline.) It should not be 
necessary to disconnect the aeration gas inlet line from the aeration 
cell when changing samples. After separating the bottle and bubbler 
sections of the aeration cell, place the bubbler section into a 600-ml 
beaker containing approximately 400 ml of deionized distilled water. 
Rinse the bottle section of the aeration cell with a stream of deionized 
distilled water to remove all traces of the tin (II) reducing agent. 
Also, to prevent the loss of Hg before aeration, remove all traces of 
the reducing agent between samples by washing with deionized distilled 
water. It will be necessary, however, to wash the aeration cell parts 
with concentrated HCl if any of the following conditions occur: (1) A 
white film appears on any inside surface of the aeration cell, (2) the 
calibration curve changes suddenly, or (3) the replicate samples do not 
yield reproducible results.
    Subtract the average peak height (or peak area) of the blank (0.0-ml 
aliquot)--which should be less than 2 percent of recorder full scale--
from the averaged peak heights of the 1.0-, 2.0-, 3.0-, 4.0-, and 5.0-ml 
aliquot standards. If the blank absorbance is greater than 2 percent of 
full-scale, the probable cause is Hg contamination of a reagent or 
carry-over of Hg from a previous sample. Plot the corrected peak height 
of each standard solution versus the corresponding final total Hg weight 
in the aeration cell (in ng) and draw the best-fit straight line. This 
line should either pass through the origin or pass through a point no 
further from the origin than plus-minus2 percent of the 
recorder full scale. If the line does not pass through or very near to 
the origin, check for nonlinearity of the curve and for incorrectly 
prepared standards.
    8.5  Sampling Train Calibration. Calibrate the sampling train 
components according to the procedures outlined in the following 
sections of Method 5: Section 5.1 (Probe Nozzle), Section 5.2 (Pitot 
Tube), Section 5.3 (Metering System), Section 5.4 (Probe Heater), 
Section 5.5 (Temperature Gauges), Section 5.7 (Barometer). Note that the 
leak-check described in Section 5.6 of Method 5 applies to this method.

9. Calculations

    9.1  Dry Gas Volume. Using the data from this test, calculate 
Vm(std), the dry gas sample volume at standard conditions 
(corrected

[[Page 218]]

for leakage, if necessary) as outlined in Section 6.3 of Method 5.
    9.2  Volume of Water Vapor and Moisture Content. Using the data 
obtained from this test, calculate the volume of water vapor 
Vw(std) and the moisture content Bws of the stack 
gas. Use Equations 5-2 and 5-3 of Method 5.
    9.3  Stack Gas Velocity. Using the data from this test and Equation 
2-9 of Method 2, calculate the average stack gas velocity vs.
    9.4  Total Mercury. For each source sample, correct the average 
maximum absorbance of the two consecutive samples whose peak heights 
agree within plus-minus3 percent of their average for the 
contribution of the solution blank (see Section 8.4). Use the 
calibration curve and these corrected averages, to determine the final 
total weight of mercury in nanograms in the aeration cell for each 
source sample. Correct for any dilutions made to bring the sample in the 
working range of the spectrophotometer. Then calculate the Hg in 
g (mHg) in the original solution as follows:

Vf=Solution volume of original sample, 1000 ml for samples 
          diluted as described in Section 7.2.1.

    9.5  Mercury Emission Rate. Calculate the Hg emission rate R in g/
day for continuous operations using Equation 101-2. For cyclic 
operations, use only the time per day each stack is in operation. The 
total Hg emission rate from a source will be the summation of results 
from all stacks.

Method 101A--Determination of Particulate and Gaseous Mercury Emissions 
                         From Stationary Sources

Introduction

    This method is similar to Method 101, except acidic potassium 
permanganate solution is used instead of acidic iodine monochloride for 
collection.


[[Page 225]]


1. Applicability and Principle

    1.1  Applicability. This method applies to the determination of 
particulate and gaseous mercury (Hg) emissions from sewage sludge 
incinerators and other sources as specified in the regulations.
    1.2  Principle. Particulate and gaseous Hg emissions are withdrawn 
isokinetically from the source and collected in acidic potassium 
permanganate (KMn04) solution. The Hg collected (in the 
mercuric form) is reduced to elemental Hg, which is then aerated from 
the solution into an optical cell and measured by atomic absorption 
spectrophotometry.

    2. Range and Sensitivity

    2.1  Range. After initial dilution, the range of this method is 20 
to 800 ng Hg/ml. The upper limit can be extended by further dilution of 
the sample.
    2.2  Sensitivity. The sensitivity of the method depends on the 
recorder/spectrophotometer combination selected.

3. Interfering Agents

    3.1  Sampling. Excessive oxidizable organic matter in the stack gas 
prematurely depletes the KMn04 solution and thereby prevents 
further collection of Hg.
    3.2  Analysis. Condensation of water vapor on the optical cell 
windows causes a positive interference.

4. Precision

    Based on eight paired-train tests, the within-laboratory standard 
deviation was estimated to be 4.8 g Hg/ml in the concentration 
range of 50 to 130 g Hg/m3.

5. Apparatus

    5.1  Sampling Train and Sample Recovery. Same as Method 101, 
Sections 5.1 and 5.2, respectively, except for the following variations:
    5.1.1  Probe Liner. Same as Method 101, Section 5.1.2, except that 
if a filter is used ahead of the impingers, the tester must use the 
probe heating system to minimize the condensation of gaseous Hg.
    5.1.2  Filter Holder (Optional). Borosilicate glass with a rigid 
stainless-steel wire-screen filter support (do not use glass frit 
supports) and a silicone rubber or Teflon gasket, designed to provide a 
positive seal against leakage from outside or around the filter. The 
filter holder must be equipped with a filter heating system capable of 
maintaining a temperature around the filter holder of 120 
plus-minus14  deg.C (248 plus-minus25  deg.F) 
during sampling to minimize both water and gaseous Hg condensation. The 
tester may use a filter in cases where the stream contains large 
quantities of particulate matter.
    5.2  Analysis. The apparatus needed for analysis is the same as 
Method 101, Sections 5.3 and 5.4, except as follows:
    5.2.1  Volumetric Pipets. Class A; 1-, 2-, 3-, 4-, 5-, 10-, and 20-
ml.
    5.2.2  Graduated Cylinder. 25-ml.
    5.2.3  Steam Bath.
    5.2.4  Atomic Absorption Spectrophotometer or Equivalent. Any atomic 
absorption unit with an open sample presentation area in which to mount 
the optical cell is suitable. Use those instrument settings recommended 
by the particular manufacturer. Instruments designed specifically for 
the measurement of mercury using the cold-vapor technique are 
commercially available and may be substituted for the atomic absorption 
spectrophotometer.
    5.2.5  Optical Cell. Alternatively, a heat lamp mounted above the 
cell or a moisture trap installed upstream of the cell may be used.
    5.2.6 Aeration Cell. Alternatively, aeration cells available with 
commercial cold vapor instrumentation may be used.
    5.2.7  Aeration Gas Cylinder. Nitrogen, argon, or dry, Hg-free air, 
equipped with a single-stage regulator. Alternatively, aeration may be 
provided by a peristaltic metering pump. If a commercial cold vapor 
instrument is used, follow the manufacturer's recommendations.

6. Reagents

    Use ACS reagent-grade chemicals or equivalent, unless otherwise 
specified.
    6.1  Sampling and Recovery. The reagents used in sampling and 
recovery are as follows:
    6.1.1  Water. Deionized distilled, meeting ASTM Specifications for 
Type I Reagent Water--ASTM Test Method D1193-77 (incorporated by 
reference--see Sec. 61.18). If high concentrations of organic matter are 
not expected to be present, the analyst may eliminate the KMnO 4 
test for oxidizable organic matter. Use this water in all dilutions and 
solution preparations.
    6.1.2  Nitric Acid (HNO3), 50 Percent (V/V). Mix equal 
volumes of concentrated HNO3 and deionized distilled water, 
being careful to slowly add the acid to the water.
    6.1.3  Silica Gel. Indicating type, 6- to 16-mesh. If previously 
used, dry at 175  deg.C (350  deg.F) for 2 hr. The tester may use new 
silica gel as received.
    6.1.4  Filter (Optional). Glass fiber filter, without organic 
binder, exhibiting at least 99.95 percent efficiency on 0.3 m 
dioctyl phthalate smoke particles. The tester may use the filter in 
cases where the gas stream contains large quantities of particulate 
matter, but he should analyze blank filters for Hg content.
    6.1.5  Sulfuric Acid (H2 SO4), 10 Percent (V/
V). Carefully add and mix 100 ml of concentrated H2 
SO4 to 800 ml of deionized distilled water. Then, by adding 
deionized distilled water, mix and bring to a final volume of 1000 ml.
    6.1.6  Absorbing Solution, 4 Percent KMnO4 (W/V). Prepare 
fresh daily. Dissolve 40 g of KMnO4 in sufficient 10 percent 
H2 SO4

[[Page 226]]

to make 1 liter. Prepare and store in glass bottles to prevent 
degradation.
    Precaution: To prevent autocatalytic decomposition of the 
permanganate solution, filter the solution through Whatman 541 filter 
paper. Also, due to the potential reaction of the potassium permanganate 
with the acid, there could be pressure buildup in the solution storage 
bottle; therefore these bottles shall not be fully filled and shall be 
vented to relieve excess pressure and prevent explosive potentials. 
Venting is required, but should not allow contamination of the solution; 
a No. 70-72 hole drilled in the container cap and Teflon liner has been 
used.
    6.1.7  Hydrochloric Acid (HCL). Concentrated. Trace-metals grade is 
recommended. The Hg level shall be less than 3 ng/ml.
    6.1.8  HCL, 8 N. Dilute 67 ml of concentrated HCl to 100 ml with 
water (slowly add the HCl to the water).
    6.2  Analysis. The reagents needed for analysis are listed below:
    6.2.1  Tin (II) Solution. Prepare fresh daily and keep sealed when 
not being used. Competely dissolve 20 g of tin (II) chloride [or 25 g of 
tin (II) sulfate] crystals (Baker Analyzed reagent grade or any other 
brand that will give a clear solution) in 25 ml of concentrated HCl. 
Dilute to 250 ml with deionized distilled water. Do not substitute 
HNO3, H2 SO4, or other strong acids for 
the HCl.
    6.2.2  Sodium Chloride--Hydroxylamine Solution. Dissolve 12 g of 
sodium chloride and 12 g of hydroxylamine sulfate (or 12 g of 
hydroxylamine hydrochloride) in deionized distilled water and dilute to 
100 ml.
    6.2.3  Hydrochloric Acid (HCl), 8 N. Dilute 67 ml of concentrated 
HCl to 100 ml with deionzed distilled water (slowly add the HCl to the 
water).
    6.2.4  Nitric Acid, 15 Percent (V/V). Dilute 15 ml of concentrated 
HNO3 to 100 ml with deionized distilled water.
    6.2.5  Mercury Stock Solution, 1 mg Hg/ml. Prepare and store all 
mercury standard solutions in borosilicate glass containers. Completely 
dissolve 0.1354 g of mercury (II) chloride in 75 ml of deionized 
distilled water. Add 100 ml of concentrated HNO3, and adjust 
the volume to exactly 100 ml with deionized distilled water. Mix 
thoroughly. This solution is stable for at least 1 month.
    6.2.6  Intermediate Mercury Standard Solution, 10 g Hg/ml. 
Prepare fresh weekly. Pipet 5.0 ml of the mercury stock solution 
(Section 6.2.5) into a 500-ml volumetric flask and add 20 ml of 15 
percent HNO3 solution. Adjust the volume to exactly 500 ml 
with deionized distilled water. Thoroughly mix the solution.
    6.2.7  Working Mercury Standard Solution, 200 ng Hg/ml. Prepare 
fresh daily. Pipet 5.0 ml from the ``Intermediate Mercury Standard 
Solution'' (Section 6.2.6) into a 250-ml volumetric flask. Add 5 ml of 4 
percent KMnO4 absorbing solution and 5 ml of 15 percent 
HNO3. Adjust the volume to exactly 250 ml with deionized 
distilled water. Mix thoroughly.
    6.2.8  Potassium Permanganate, 5 Percent (W/V). Dissolve 5 g of 
KMnO4 in deionized distilled water and dilute to 100 ml.
    6.2.9  Filter. Whatman No. 40 or equivalent.

7. Procedure

    7.1  Sampling. The sampling procedure is the same as Method 101, 
except for changes due to the use of KMnO4 instead of ICl 
absorbing solution and the possible use of a filter. These changes are 
as follows:
    7.1.1  Preliminary Determinations. The preliminary determinations 
are the same as those given in Method 101, section 7.1.2, except for the 
absorbing solution depletion sign. In this method, highly oxidizable 
matter could make it impossible to sample for the required minimum time. 
This problem is indicated by the complete bleaching of the purple color 
of the KMnO4 solution. In these cases, the tester may divide 
the sample run into two or more subruns to insure that the absorbing 
solution would not be depleted. In cases where an excess of water 
condensation is encountered, collect two runs to make one sample, or add 
an extra impinger in front of the first impinger (also containing 
acidified KMnO4 solution).
    7.1.2  Preparation of Sampling Train. The preparation of the 
sampling train is the same as that given in Method 101, section 7.1.3, 
except for the cleaning of the glassware [probe, filter holder (if 
used), impingers, and connectors] and the charging of the first three 
impingers. In this method, clean all the glass components (a hood is 
recommended) by rinsing with 50 percent HNO3, tap water, 8 N 
HCl, tap water, and finally deionized distilled water. Then place 50 ml 
of the acidified 4 percent KMnO4 absorbing solution in the 
first impinger and 100 ml in each of the second and third impingers.
    If a filter is used, use a pair of tweezers to place the filter in 
the filter holder. Be sure to center the filter and place the gasket in 
proper position to prevent the sample gas stream from by-passing the 
filter. Check the filter for tears after assembly is completed. Be sure 
also to set the filter heating system at the desired operating 
temperature after the sampling train has been assembled.
    7.1.3  Sampling Train Operation. In addition to the procedure given 
in Method 101, section 7.1.5, maintain a temperature around the filter 
(if applicable) of 120 deg.plus-minus14  deg.C 
(248 deg.plus-minus25  deg.F).
    7.2  Sample Recovery. Begin proper cleanup procedure as soon as the 
probe is removed from the stack at the end of the sampling period. Allow 
the probe to cool. When it can be

[[Page 227]]

safely handled, wipe off any external particulate matter near the tip of 
the probe nozzle and place a cap over it. Do not cap off the probe tip 
tightly while the sampling train is cooling because the resultant vacuum 
would draw liquid out from the impingers.
    Before moving the sample train to the cleanup site, remove the probe 
from the train, wipe off the silicone grease, and cap the open outlet of 
the probe. Be careful not to lose any condensate that might be present. 
Wipe off the silicone grease from the impinger. Use either ground-glass 
stoppers, plastic caps, or serum caps to close these openings.
    Transfer the probe, impinger assembly, and (if applicable) filter 
assembly to a cleanup area that is clean, protected from the wind, and 
free of Hg contamination. The ambient air in laboratories located in the 
immediate vicinity of Hg-using facilities is not normally free of Hg 
contamination.
    Inspect the train before and during assembly, and note any abnormal 
conditions. Treat the sample as follows:
    7.2.1  Container No. 1 (Impinger, Probe, and Filter Holder) and, if 
applicable, No. 1A (HCl rinse).
    7.2.1.1  Using a graduated cylinder, measure the liquid in the first 
three impingers to within 1 ml. Record the volume of liquid present 
(e.g., see Figure 5-3 of Method 5 in 40 CFR Part 60). This information 
is required to calculate the moisture content of the effluent gas. (Use 
only graduated cylinder and glass storage bottles that have been 
precleaned as in Section 7.1.2.) Place the contents of the first three 
impingers into a 1000-ml glass sample bottle labeled Container No. 1. 
See the Precaution in Section 6.1.6.

    Note No. 1 to Section 7.2.1.1: Due to the potential reaction of 
KMnO4 with acid, there could be pressure buildup in the 
sample storage bottles. These bottles shall not be filled completely and 
shall be vented to relieve excess pressure. A No. 70-72 hole drilled in 
the container cap and Teflon liner has been used successfully).
    Note No. 2 to Section 7.2.1.1: If a filter is used in the sampling 
train, remove the filter from its holder as outlined under ``Container 
No. 3'' below.)

    7.2.1.2  Taking care that dust on the outside of the probe or other 
exterior surfaces does not get into the sample, quantitatively recover 
the Hg (and any condensate) from the probe nozzle, probe fitting, probe 
liner, front half of the filter holder (if applicable), and impingers as 
follows: Rinse these components with a total of 250 to 400 ml of fresh 
acidified 4 percent KMnO4 solution carefully assuring removal 
of all loose particulate matter from the impingers; add all washings to 
Container No. 1. See the Precaution in Section 6.1.6 and see the Note 
No. 1 in Section 7.2.1.1. To remove any residual brown deposits on the 
glassware following the permanganate rinse, rinse with approximately 100 
ml of water carefully assuring removal of all loose particulate matter 
from the impingers, and add this rinse to Container No. 1. If no visible 
deposits remain after this water rinse, do not rinse with 8 N HCl. 
However, if deposits do remain on the glassware after the water rinse, 
wash the impinger walls and stems with a total of only 25 ml of 8 N HCl 
as follows; turn and shake the impingers so that the 8 N HCl contacts 
all inside surfaces (wash the first impinger, then pour the wash from 
the first impinger into the second impinger, and finally pour the wash 
from the second into the third). DO NOT PLACE THE HCl WASH INTO THE 
ACIDIFIED PERMANGANATE SOLUTION. Place the HCl wash into a separate 
container labeled Container No. 1A as follows: place 150 ml of water in 
an empty sample container labeled Container No. 1A. Pour the HCl wash 
carefully, with stirring, into Container No. 1A. Rinse the impinger 
walls and stem with a total of 50 ml of water, and place this rinse into 
Container No. 1A.
    7.2.1.3  After all washings have been collected in the sample 
containers, prepare as described above to prevent leakage during 
shipment to the laboratory. Mark the height of the fluid level to 
determine whether leakage occurs during transport. Label the containers 
to identify their contents clearly.
    7.2.2.  Container No. 2 (Silica Gel). Note the color of the 
indicating silica gel to determine whether it has been completely spent 
and make a notation of its condition. Transfer the silica gel from its 
impinger to its original container and seal. The tester may use as aids 
a funnel to pour the silica gel and a rubber policeman to remove the 
silica gel from the impinger. It is not necessary to remove the small 
amount of particles that may adhere to the impinger wall and are 
difficult to remove. Since the gain in weight is to be used for moisture 
calculations, do not use any water or other liquids to transfer the 
silica gel. If a balance is available in the field, weigh the spent 
silica gel (or silica gel plus impinger) to the nearest 0.5 g; record 
this weight.
    7.2.3  Container No, 3 (Filter). If a filter was used, carefully 
remove it from the filter holder, place it into a 100 ml glass sample 
container, and add 20 to 40 ml of acidified KMnO4. If it is 
necessary to fold the filter, be sure that the particulate cake is 
inside the fold. Carefully transfer to the 100 ml sample bottle any 
particulate matter and filter fibers that might adhere to the filter 
holder gasket by using a dry Nylon bristle brush and a sharp edged 
blade. See the Precaution in Section 6.1.6 and see the Note No. 1 in 
Section 7.2.1.1. Label the container to clearly identify its contents. 
Mark the height of the fluid level to determine whether leakage occurs 
during transport.

[[Page 228]]

    7.2.4  Container No. 4 (Filter Blank). If a filter was used, treat 
an unused filter from the same filter lot used for sampling in the same 
manner as Container No. 3.
    7.2.5  Container No, 5 (Absorbing Solution Blank). For a blank, 
place 500 ml of acidified absorbing solution in a 1000 ml sample bottle. 
See the Precaution in Section 6.1.6 and see the Note No. 1 in Section 
7.2.1.1.
    7.2.6  Container No. 6 (HCl rinse blank). For a blank, place 200 ml 
of water in a 1000-ml sample bottle, and add 25 ml of 8 N HCl carefully 
with stirring. Seal the container. Only one blank sample per 3 runs is 
required.
    7.3  Sample preparation. Check liquid level in each container to see 
if liquid was lost during transport. If a noticeable amount of leakage 
occurred, either void the sample or use methods subject to the approval 
of the Administrator to account for the losses. Then follow the 
procedures below.
    7.3.1  Containers No. 3 and No. 4 (Filter and Filter Blank). If a 
filter is used, place the contents, including the filter, of Containers 
No. 3 and 4 in separate 250-ml beakers, and heat the beakers on a steam 
bath until most of the liquid has evaporated. Do not take to dryness. 
Add 20 ml of concentrated HNO3 to the beakers, cover them 
with a watch glass, and heat on a hot plate at 70  deg.C for 2 hours. 
Remove from the hot plate. Filter the solution from digestion of the 
Container No. 3 contents through Whatman No. 40 filter paper, and save 
the filtrate for addition to the Container No. 1 filtrate as described 
in Section 7.3.2. Discard the filter. Filter the solution from the 
digestion of the Container No. 4 contents through Whatman No. 40 filter 
paper, and save the filtrate for addition to Container No. 5 filtrate as 
described in Section 7.3.3. Discard the filter.
    7.3.2  Container No. 1 (Impingers, Probe, and Filter Holder) and, if 
applicable, No. 1A (HCl rinse). Filter the contents of Container No. 1 
through Whatman 40 filter paper into a 1-liter volumetric flask to 
remove the brown MnO2 precipitate. Save the filter for 
digestion of the brown MnO2 precipitate. Add the sample 
filtrate from Container No. 3 to the 1-liter volumetric flask, and 
dilute to volume with water. If the combined filtrates are greater than 
1000 ml, determine the volume to the nearest ml and make the appropriate 
corrections for blank subtractions. Mix thoroughly. Mark the combined 
filtrates as ANALYSIS SAMPLE No. A.1. and analyze for Hg within 48 hr of 
the filtration step (Note: Do not confuse ANALYSIS SAMPLE No. A.1. with 
the contents of field Sample Container No. 1A which contains the 8 N HCl 
wash). Place the saved filter, which was used to remove the brown 
MnO2 precipitate, into an appropriate sized vented container, 
which will allow release of any gases including chlorine formed when the 
filter is digested. In a laboratory hood which will remove any gas 
produced by the digestion of the MnO2, add 25 ml of 8 N HCl 
to the filter and allow to digest for a minimum of 24 hours at room 
temperature. Filter the contents of Container 1A through Whatman 40 
paper into a 500-ml volumetric flask. Then filter the result of the 
digestion of the brown MnO2 from Container No. 1 through 
Whatman 40 filter into the same 500-ml volumetric flask, and dilute and 
mix well to volume with water. Discard the filter. Mark this combined 
500-ml dilute solution as ANALYSIS SAMPLE No. HCL A.2., and analyze for 
Hg.
    7.3.3  Container No. 5 (Absorbing Solution Blank) and No. 6 (HCl 
Rinse Blank). Prepare the contents of Container No. 5 for analysis by 
the same procedure used for Container No. 1 as described in Section 
7.3.2. Add the filter blank filtrate from Container No. 4 to the 1-liter 
volumetric flask, and dilute to volume. Mix thoroughly. Mark this as 
ANALYSIS SAMPLE No. A.1. BLANK, and analyze for Hg within 48 hours of 
the filtration step. Digest any brown precipitate remaining on the 
filter from the filtration of Container No. 5 by the same procedure as 
described in Section 7.3.2. Filter the contents of Container No. 6 by 
the same procedure as described in Section 7.3.2, and combine in the 
500-ml volumetric flask with the filtrate from the digested blank 
MnO2 precipitate. Mark this resultant 500-ml combined dilute 
solution as ANALYSIS SAMPLE No. HCl A.2 blank. (Note: When analyzing 
samples A.1 blank and HCl A.2 blank, always begin with 10-ml aliquots. 
This applies specifically to blank samples.)
    7.4  Analysis. Calibrate the spectrophotometer and recorder and 
prepare the calibration curve as described in sections 8.1 and 8.2. Then 
repeat the procedure used to establish the calibration curve with 
appropriately sized aliquots (1 to 10 ml) of the samples (from sections 
7.3.2 and 7.3.3) until two consecutive peak heights agree within 
plus-minus3 percent of their average value. If the 10-ml 
sample is below the detectable limit, use a larger aliquot (up to 20 
ml), but decrease the volume of water added to the aeration cell 
accordingly to prevent the solution volume from exceeding the capacity 
of the aeration bottle. If the peak maximum of a 1.0-ml aliquot is off 
scale, further dilute the original sample to bring the Hg concentration 
into the calibration range of the spectrophotometer. If the Hg content 
of the absorbing solution and filter blank is below the working range of 
the analytical method, use zero for the blank.
    Run a blank and standard at least after every five samples to check 
the spectrophotometer calibration; recalibrate as necessary.
    It is also recommended that at least one sample from each stack test 
be checked by the Method of Standard Additions to confirm

[[Page 229]]

that matrix effects have not interfered in the analysis.

8. Calibration and Standards

    The calibration and standards are the same as Method 101, Section 8, 
except for the following variations:
    8.1  Optical Cell Heating System Calibration. Same as Method 101, 
Section 8.2, except use a 25-ml graduated cylinder to add 25 ml of 
deionized distilled water to the bottle section of the aeration cell.
    8.2  Spectrophotometer and Recorder Calibration. The mercury 
response may be measured by either peak height or peak area. (Note: The 
temperature of the solution affects the rate at which elemental Hg is 
released from a solution and, consequently, it affects the shape of the 
absorption curve (area) and the point of maximum absorbance (peak 
height). To obtain reproducible results, all solutions must be brought 
to room temperature before use.) Set the spectrophotometer wave length 
at 253.7 nm and make certain the optical cell is at the minimum 
temperature that will prevent water condensation.
    Then set the recorder scale as follows: Using a 25-ml graduated 
cylinder, add 25 ml of deionized distilled water to the aeration cell 
bottle and pipet 5.0 ml of the working mercury standard solution into 
the aeration cell. (Note: Always add the Hg-containing solution to the 
aeration cell after the 25 ml of deionized distilled water.) Place a 
Teflon-coated stirring bar in the bottle. Add 5 ml of the 4 percent 
KMnO4 absorbing solution followed by 5 ml of 15 percent 
HNO3 and 5 ml of 5 percent KMnO4 to the aeration 
bottle and mix well. Now, attach the bottle section to the bubbler 
section of the aeration cell and make certain that (1) the aeration cell 
exit arm stopcock (Figure 101-3 of Method 101) is closed (so that Hg 
will not prematurely enter the optical cell when the reducing agent is 
being added) and (2) there is no flow through the bubbler. Add 5 ml of 
sodium chloride hydroxylamine in 1-ml increments until the solution is 
colorless. Now add 5 ml of tin (II) solution to the aeration bottle 
through the side arm, and immediately stopper the side arm. Stir the 
solution for 15 seconds, turn on the recorder, open the aeration cell 
exit arm stopcock, and immediately initiate aeration with continued 
stirring. Determine the maximum absorbance of the standard and set this 
value to read 90 percent of the recorder full scale.

9. Calculations

Stack Gas Velocity, Isokinetic Variation and Acceptable Results, and 
Determination of Compliance. Same as Method 101, sections 9.1, 9.2, 9.3, 
9.6, and 9.7, respectively, except use data obtained from this test.
    9.2  Total Mercury. For each source sample, correct the average 
maximum absorbance of the two consecutive samples whose peak heights 
agree within 3 percent of their average for the contribution of the 
blank. Then calculate the total Hg content in  g in each 
sample. Correct for any dilutions made to bring the sample into the 
working range of the spectrophotometer.

          volume has been factored out in the equation along with the 
          sample aliquot (S). In Eq. 101A-1, the sample aliquot, S, is 
          digested according to Sections 7.4, 8.1, and 8.2 and the Hg 
          from this digestion is introduced directly into the aeration 
          cell for analysis. A dilution factor is required only if it is 
          necessary to bring the sample into the analytical instrument's

 Method 102--Determination of Particulate and Gaseous Mercury Emissions 
               From Chlor-Alkali Plants--Hydrogen Streams

1. Introduction

    Although similar to Method 101, Method 102 requires changes to 
accommodate the sample being extracted from a hydrogen stream. Conduct 
the test according to Method 101, except as shown below:

2. Mercury Train Operation

    2.1  Probe Heating System. Do not use, unless otherwise specified.
    2.2  Glass Fiber Filter. Do not use, unless otherwise specified.
    2.3  Safety Procedures. The sampler must conduct the source test 
under conditions of utmost safety, because hydrogen and air mixtures are 
explosive. Since the sampling train essentially is leakless, attention 
to safe operation can be concentrated at the inlet and outlet. If a leak 
does occur, however, remove the meter box cover to avoid a possible 
explosive mixture. The following specific precautions are recommended:
    2.3.1  Operate only the vacuum pump during the test. The other 
electrical equipment, e.g., heaters, fans, and timers, normally are not 
essential to the success of a hydogen stream test.
    2.3.2  Seal the sample port to minimize leakage of hydrogen from the 
stack.
    2.3.3  Vent sampled hydrogen at least 3 m (10 feet) away from the 
train. This can be accomplished by attaching a 13-mm-ID (0.50-in.) Tygon 
tube to the exhaust from the orifice meter. (Note: A smaller ID tubing 
may cause the orifice meter calibration to be erroneous.) Take care to 
ensure that the exhaust line is not bent or pinched.
    2.4  Setting of Isokinetic Rates.
    2.4.1  If a nomograph is used, take special care in the calculation 
of the molecular weight of the stack gas and in the setting of the 
nomograph to maintain isokinetic conditions during sampling (sections 
2.4.1.1 through 2.4.1.3 below).
    2.4.1.1  Calibrate the meter box orifice. Use the techniques 
described in APTD-0576 (see Citation 9 in section 10 of Method 101). 
Calibration of the orifice meter at flow conditions that simulate the 
conditions at the source is suggested. Calibration should either be done 
with hydrogen or with some other gas having a similar Reynolds Number so 
that there is similarity between the Reynolds Numbers during calibration 
and during sampling.
    2.4.1.2  The nomograph described in APTD-0576 cannot be used to 
calculate the C factor because the nomograph is designed for use when 
the stack gas dry molecular weight is 29plus-minus4. Instead, 
the following calculation should be made to determine the proper C 
factor:
[GRAPHIC] [TIFF OMITTED] TC15NO91.062

Where:

 H@=Meter box calibration factor obtained in Section 
          2.4.1.1, in. H2 O.
Cp=Pitot tube calibration coefficient, dimensionless.
Tm=Absolute temperature of gas at the orifice,  deg.R.
Ps=Absolute pressure of stack gas, in. Hg.
Pm=Absolute pressure of gas at the meter, in. Hg.
Bws=Fraction by volume of water vapor in the stack gas.
Md=Dry molecular weight of stack gas, 1b/1b-mole.
0.00154=(in. H2 O) ( deg. R)
    Note. This calculation is left in English units, and is not 
converted to metric units because nomographs are based on English units.
    2.4.1.3  Set the calculated C factor on the operating nomograph and 
select the proper nozzle diameter and K factor as specified in APTD-
0576. If the C factor obtained in Section 2.4.1.2 exceeds the values 
specified on the existing operating nomograph, expand the C scale 
logarithmically so that the values can be properly located.
    2.4.2  If a calculator is used to set isokinetic rates, it is 
suggested that the isokinetic equation presented in Citation 17 in the 
Bibliography of Method 101 be used.
    2.5  Sampling in Small (<12-in.-Diameter) Stacks. When the stack 
diameter (or equivalent diameter) is less than 12 inches, conventional 
pitot tube-probe assemblies should not be used. For sampling guidelines, 
see Citation 18 in the Bibliography of Method 101.

                 Method 103--Beryllium Screening Method

1. Applicability and Principle

    1.1  Applicability. This procedure details guidelines and 
requirements for methods acceptable for use in determining beryllium 
(Be) emissions in ducts or stacks at stationary sources.
    1.2  Principle. Be emissions are isokinetically sampled from three 
points in a duct or

[[Page 232]]

stack. The collected sample is analyzed for Be using an appropriate 
technique.

2. Apparatus

    2.1  Sampling Train. A schematic of the required sampling train 
configuration is shown in Figure 103-1. The essential components of the 
train are the following:
[GRAPHIC] [TIFF OMITTED] TC01MY92.028

    2.1.1  Nozzle. Stainless steel, or equivalent, with sharp, tapered 
leading edge.
    2.1.2  Probe. Sheathed borosilicate or quartz glass tubing.
    2.1.3  Filter. Millipore AA (Note: Mention of trade names or 
specific products does not constitute endorsement by the Environmental 
Protection Agency), or equivalent, with appropriate filter holder that 
provides a positive seal against leakage from outside or around the 
filter. It is suggested that a Whatman 41, or equivalent, be placed 
immediately against the back side of the Millipore filter as a guard 
against breakage of the Millipore. Include the backup filter in the 
analysis. To be equivalent, other filters shall exhibit at least 99.95 
percent efficiency (0.05 percent penetration) on 0.3 micron dioctyl 
phthalate smoke particles, and be amenable to the Be analysis procedure. 
The filter efficiency tests shall be conducted in accordance with 
American Society for Testing and Materials (ASTM) Standard Method D 
2986-71 (reapproved 1978) (incorporated by reference--see Sec. 61.18). 
Test data from the supplier's quality control program are sufficient for 
this purpose.
    2.1.4  Meter-Pump System. Any system that will maintain isokinetic 
sampling rate, determine sample volume, and is capable of a sampling 
rate of greater than 14 1pm (0.5 cfm).
    2.2  Measurement of Stack Conditions. The following equipment is 
used to measure stack conditions:
    2.2.1  Pitot Tube. Type S, or equivalent, with a coefficient within 
5 percent over the working range.
    2.2.2  Inclined Manometer, or Equivalent. To measure velocity head 
to within 10 percent of the minimum value.
    2.2.3  Temperature Measuring Device. To measure stack temperature to 
within 1.5 percent of the minimum absolute stack temperature.
    2.2.4  Pressure Measuring Device. To measure stack pressure to 
within 2.5 mm Hg (0.1 in. Hg).
    2.2.5  Barometer. To measure atmospheric pressure to within 2.5 mm 
Hg (0.1 in. Hg).
    2.2.6  Wet and Dry Bulb Thermometers, Drying Tubes, Condensers, or 
Equivalent. To determine stack gas moisture content to within 1 percent.
    2.3  Sample Recovery.
    2.3.1  Probe Cleaning Equipment. Probe brush or cleaning rod at 
least as long as probe, or equivalent. Clean cotton balls, or 
equivalent, should be used with the rod.
    2.3.2  Leakless Glass Sample Bottles. To contain sample.
    2.4  Analysis. Use equipment necessary to perform an atomic 
absorption, spectrographic, fluorometric, chromatographic, or equivalent 
analysis.

3. Reagents

    3.1  Sample Recovery.
    3.1.1  Water. Distilled water.
    3.1.2  Acetone. Reagent grade.
    3.1.3  Wash Acid, 50 Percent (V/V) Hydrochloric Acid (HCl).

[[Page 233]]

    Mix equal volumes of concentrated HCl and water, being careful to 
add the acid slowly to the water.
    3.2  Analysis. Reagents as necessary for the selected analytical 
procedure.

4. Procedure

    Guidelines for source testing are detailed in the following 
sections. These guidelines are generally applicable; however, most 
sample sites differ to some degree and temporary alterations such as 
stack extensions or expansions often are required to insure the best 
possible sample site. Further, since Be is hazardous, care should be 
taken to minimize exposure. Finally, since the total quantity of Be to 
be collected is quite small, the test must be carefully conducted to 
prevent contamination or loss of sample.
    4.1  Selection of a Sampling Site and Number of Sample Runs. Select 
a suitable sample site that is as close as practicable to the point of 
atmospheric emission. If possible, stacks smaller than 1 foot in 
diameter should not be sampled.
    4.1.1  Ideal Sampling Site. The ideal sampling site is at least 
eight stack or duct diameters downstream and two diameters upstream from 
any flow disturbance such as a bend, expansion or contraction. For 
rectangular cross sections, use Equation 103-1 to determine an 
equivalent diameter, De.
[GRAPHIC] [TIFF OMITTED] TC15NO91.063

Where:

L=length
W=width

    4.1.2  Alternate Sampling Site. Some sampling situations may render 
the above sampling site criteria impractical. In such cases, select an 
alternate site no less than two diameters downstream and one-half 
diameter upstream from any point of flow disturbance. Additional sample 
runs are recommended at any sample site not meeting the criteria of 
section 4.1.1.
    4.1.3  Number of Sample Runs Per Test. Three sample runs constitute 
a test. Conduct each run at one of three different points. Select three 
points that proportionately divide the diameter, or are located at 25, 
50, and 75 percent of the diameter from the inside wall. For horizontal 
ducts, sample on a vertical line through the centroid. For rectangular 
ducts, sample on a line through the centroid and parallel to a side. If 
additional sample runs are performed per section 4.1.2, proportionately 
divide the duct to accommodate the total number of runs.
    4.2  Measurement of Stack Conditions. Using the equipment described 
in section 2.2, measure the stack gas pressure, moisture, and 
temperature to determine the molecular weight of the stack gas. Sound 
engineering estimates may be made in lieu of direct measurements. 
Describe the basis for such estimates in the test report.
    4.3  Preparation of Sampling Train. Assemble the sampling train as 
shown in Figure 103-1. It is recommended that all glassware be 
precleaned by soaking in wash acid for 2 hours.
    Leak check the sampling train at the sampling site. The leakage rate 
should not be in excess of 1 percent of the desired sample rate.
    4.4  Beryllium Train Operation. For each run, measure the velocity 
at the selected sampling point. Determine the isokinetic sampling rate. 
Record the velocity head and the required sampling rate. Place the 
nozzle at the sampling point with the tip pointing directly into the gas 
stream. Immediately start the pump and adjust the flow to isokinetic 
conditions. At the conclusion of the test, record the sampling rate. 
Again measure the velocity head at the sampling point. The required 
isokinetic rate at the end of the period should not have deviated more 
than 20 percent from that originally calculated. Describe the reason for 
any deviation beyond 20 percent in the test report.
    Sample at a minimum rate of 14 1pm (0.5 cfm). Obtain samples over 
such a period or periods of time as are necessary to determine the 
maximum emissions which would occur in a 24-hour period. In the case of 
cyclic operations, perform sufficient sample runs so as to allow 
determination or calculation of the emissions that occur over the 
duration of the cycle. A minimum sampling time of 2 hours per run is 
recommended.
    4.5  Sample Recovery. It is recommended that all glassware be 
precleaned as in section 4.3. Sample recovery should also be performed 
in an area free of possible Be contamination. When the sampling train is 
moved, exercise care to prevent breakage and contamination. Set aside a 
portion of the acetone used in the sample recovery as a blank for 
analysis. The total amount of acetone used should be measured for 
accurate blank correction. Blanks can be eliminated if prior analysis 
shows negligible amounts.
    Remove the filter (and backup filter, if used) and any loose 
particulate matter from filter holder, and place in a container.
    Clean the probe with acetone and a brush or long rod and cotton 
balls. Wash into the container with the filter. Wash out the filter 
holder with acetone, and add to the same container.
    4.6  Analysis. Make the necessary preparation of samples and analyze 
for Be. Any currently acceptable method such as atomic absorption, 
spectrographic, fluorometric, chromatographic, or equivalent may be 
used.

5. Calibration and Standards

    5.1  Sampling Train. As a procedural check, compare the sampling 
rate regulation with a dry gas meter, spirometer, rotameter

[[Page 234]]

(calibrated for prevailing atmospheric conditions), or equivalent, 
attached to the nozzle inlet of the complete sampling train.
    5.2  Analysis. Perform the analysis standardization as suggested by 
the manufacturer of the instrument, or the procedures for the analytical 
method in use.

6. Calculations

    Calculate the Be emission rate R in g/day for each stack using 
Equation 103-2. For cyclic operations, use only the time per day each 
stack is in operation. The total Be emission rate from a source is the 
summation of results from all stacks.

7. Test Report

    Prepare a test report that includes as a minimum: A detailed 
description of the sampling train used, results of the procedural check 
described in Section 5.1 with all data and calculations made, all 
pertinent data taken during the test, the basis for any estimates made, 
isokinetic sampling calculations, and emission results. Include a 
description of the test site, with a block diagram and brief description 
of the process, location of the sample points in the stack cross 
section, and stack dimensions and distances from any point of 
disturbance.

Method 104--Determination of Beryllium Emissions From Stationary Sources

1. Applicability and Principle

    1.1  Applicability. This method is applicable for the determination 
of beryllium (Be) emissions in ducts or stacks at stationary sources. 
Unless otherwise specified, this method is not intended to apply to gas 
streams other than those emitted directly to the atmosphere without 
further processing.
    1.2  Principle. Be emissions are isokinetically sampled from the 
source, and the collected sample is digested in an acid solution and 
analyzed by atomic absorption spectrophotometry.

    2. Apparatus

    2.1  Sampling Train. The sampling train is identical to the Method 5 
train as shown in Figure 5-1 (mention of Method 5 refers to 40 CFR part 
60). The sampling train consists of the following components:
    2.1.1  Probe Nozzle, Pitot Tube, Differential Pressure Gauge, 
Metering System, Barometer, and Gas Density Determination Equipment. 
Same as Method 5, Sections 2.1.1, 2.1.3, 2.1.4, 2.1.8, 2.1.9, and 
2.1.10, respectively.
    2.1.2  Probe Liner. Borosilicate or quartz glass tubing. The tester 
may use a heating system capable of maintaining a gas temperature of 
12014  deg.C (24825  deg.F) at the probe exit 
during sampling to prevent water condensation. Note: Do not use metal 
probe liners.
    2.1.3  Filter Holder. Borosilicate glass, with a glass frit filter 
support and a silicone rubber gasket. Other materials of construction 
(e.g., stainless steel, Teflon, Viton) may be used, subject to the 
approval of the Administrator. (Note: Mention of trade names of specific 
products does not constitute endorsement by the Environmental Protection 
Agency.) The holder design shall provide a positive seal against leakage 
from the outside or around the filter. The holder shall be attached 
immediately at the outlet of the probe. A heating system capable of 
maintaining the filter at a minimum temperature in the range of the 
stack temperature may be used to prevent condensation from occurring.
    2.1.4  Impingers. Four Greenburg-Smith impingers connnected in 
series with leak-free ground glass fittings or any similar leak-free 
noncontaminating fittings. For the first, third, and fourth impingers, 
the tester may use impingers that are modified by replacing the tip with 
a 13-mm-ID (0.5-in.) glass tube extending to 13 mm (0.5 in.) from the 
bottom of the flask.
    2.2  Sample Recovery. The following items are needed:
    2.2.1  Probe Cleaning Rod. At least as long as probe.
    2.2.2  Glass Sample Bottles. Leakless, with Teflon-lined caps, 500-
ml.
    2.2.3  Graduated Cylinder. 250-ml.
    2.2.4  Funnel and Rubber Policeman. To aid in transfer of silica gel 
to container; not necessary if silica gel is weighed in the field.
    2.2.5  Funnel. Glass, to aid in sample recovery.
    2.2.6  Plastic Jar. Approximately 300-ml.
    2.3  Analysis. The following equipment is needed:
    2.3.1  Atomic Absorption Spectrophotometer. Perkin-Elmer 303, or 
equivalent, with nitrous oxide/acetylene burner.
    2.3.2  Hot Plate.
    2.3.3  Perchloric Acid Fume Hood.

3. Reagents

    Use ACS reagent-grade chemicals or equivalent, unless otherwise 
specified.
    3.1  Sampling and Recovery. The reagents used in sampling and 
recovery are as follows:

[[Page 235]]

    3.1.1  Filter. Millipore AA, or equivalent. It is suggested that a 
Whatman 41 filter or equivalent be placed immediately against the back 
side of the Millipore filter as a guard against breaking the Millipore 
filter. To be equivalent, other filters shall exhibit at least 99.95 
percent efficiency (0.05 percent penetration) on 0.3 micron dioctyl 
phthalate smoke particles. The filter efficiency tests shall be 
conducted in accordance with ASTM Standard Method D 2986-71 (reapproved 
1978) (incorporated by reference--see Sec. 61.18). Test data from the 
supplier's quality control program are sufficient for this purpose.
    3.1.2  Water. Deionized distilled, meeting ASTM Specifications for 
Type 3 Reagent Water--ASTM Test Method D 1193-77 (incorporated by 
reference--see Sec. 61.18). If high concentrations of organic matter are 
not expected to be present, the analyst may eliminate the 
KMnO4 test for oxidizable organic matter.
    3.1.3  Silica Gel. Indicating type, 6- to 16-mesh. If previously 
used, dry at 175 deg. C (350 deg. F) for 2 hours. The tester may use new 
silica gel as received.
    3.1.4  Acetone.
    3.1.5  Wash Acid, 50 Percent (V/V) Hydrochloric Acid (HCl).
    Mix equal volumes of concentrated HCl and water, being careful to 
add the acid slowly to the water.
    3.2  Sample Preparation and Analysis. The reagents needed are listed 
below:
    3.2.1  Water. Same as Section 3.1.2.
    3.2.2.  Perchloric Acid (HClO4). Concentrated (70 
percent).
    3.2.3  Nitric Acid (HNO3). Concentrated.
    3.2.4  Beryllium Powder. Minimum purity 98 percent.
    3.2.5  Sulfuric Acid (H2SO4) Solution, 12 N. 
Dilute 33 ml of concentrated H2SO4 to 1 liter with 
water.
    3.2.6  Hydrochloric Acid Solution, 25 Percent HCl (V/V).
    3.2.7  Standard Beryllium Solution, 1 g Be/ml. Dissolve 10 
mg of Be in 80 ml of      12 N H2SO4 solution, and 
dilute to 1000 ml with water. Dilute a 10-ml aliquot to 100 ml with 25 
percent HCl solution to give a concentration of 1 g/ml. Prepare 
this dilute stock solution fresh daily. Equivalent strength Be stock 
solutions may be prepared from Be salts such as BeCl2 and 
Be(NO3)2 (98 percent minimum purity).

4. Procedure

    4.1  Sampling. Because of the complexity of this method testers 
should be trained and experienced with the test procedures to assure 
reliable results. As Be is hazardous, testers should take precautions to 
minimize exposure. The amount of Be that is collected is generally 
small, therefore, it is necessary to exercise particular care to prevent 
contamination or loss of sample.
    4.1.1  Pretest Preparation. Follow the general procedure given in 
Method 5 ,section 4.1.1. Omit the directions for filters, except check 
them visually against light for irregularities and flaws such as 
pinholes.
    4.1.2  Preliminary Determinations. Follow the general procedure 
given in Method 5, section 4.1.2, except as follows: Select a nozzle 
size based on the range of velocity heads to assure that it is not 
necessary to change the nozzle size in order to maintain isokinetic 
sampling rates below 28 liters/min (1.0 cfm).
    Obtain samples over a period or periods of time that accurately 
determine the maximum emissions that occur in a 24-hour period. In the 
case of cyclic operations, perform sufficient sample runs for the 
accurate determination of the emissions that occur over the duration of 
the cycle. A minimum sample time of 2 hours per run is recommended.
    4.1.3  Prior to assembly, clean all glassware (probe, impingers, and 
connectors) by first soaking in wash acid for 2 hours, followed by 
rinsing with water. Place 100 ml of water in each of the first two 
impingers, and leave the third impinger empty. Save a portion of the 
water for a blank analysis. Place approximately 200 g of preweighed 
silica gel in the fourth impinger. The tester may use more silica gel, 
but should be careful to ensure that it is not entrained and carried out 
from the impinger during sampling. Place the silica gel container in a 
clean place for later use in the sample recovery. As an alternative, 
determine and record the weight of the silica gel plus impinger to the 
nearest 0.5 g.
    Install the selected nozzle using a Viton A O-ring when stack 
temperatures are less the 260 deg.C (500 deg.F). Use a fiberglass string 
gasket if temperatures are higher. See APTD-0576 (Citation 9 in Section 
10 of Method 101) for details. Other connecting systems using either 316 
stainless steel or Teflon ferrules may be used.
    If condensation in the probe or filter is a problem, probe and 
filter heaters will be required. Adjust the heaters to provide a 
temperature at or above the stack temperature. However, membrane filters 
such as the Millipore AA are limited to about 225 deg. F. If the stack 
gas is in excess of about 200 deg. F, consideration should be given to 
an alternate procedure such as moving the filter holder downstream of 
the first impinger to insure that the filter does not exceed its 
temperature limit. Mark the probe with heat-resistant tape or by some 
other method to denote the proper distance into the stack or duct for 
each sampling point. Assemble the train as shown in Figure 5-1 of Method 
5, using (if necessary) a very light coat of silicone grease on all 
ground glass joints. Grease only the outer portion (see APTD-0576) to 
avoid possibility of contamination by the silicone

[[Page 236]]

grease. Note: An empty impinger may be inserted between the third 
impinger and the silica gel to remove excess moisture from the sample 
stream.
    After the sampling train has been assembled, turn on and set the 
probe, if applicable, at the desired operating temperature. Allow time 
for the temperatures to stabilize. Place crushed ice around the 
impingers.
    4.1.4.  Leak-Check Procedures. Follow the leak-check procedures 
outlined in Method 5, Sections 4.1.4.1 (Pretest Leak Check), 4.1.4.2 
(Leak Checks During Sample Run), and 4.1.4.3 (Post-Test Leak Check).
    4.1.5  Beryllium Train Operation. Follow the general procedure given 
in Method 5, Section 4.1.5. For each run, record the data required on a 
data sheet such as the one shown in Figure 5-2 of Method 5.
    4.1.6  Calculation of Percent Isokinetic. Same as Method 5, Section 
4.1.6.
    4.2  Sample Recovery. Begin proper cleanup procedure as soon as the 
probe is removed from the stack at the end of the sampling period.
    Allow the probe to cool. When it can be safely handled, wipe off any 
external particulate matter near the tip of the probe nozzle, and place 
a cap over it. Do not cap off the probe tip tightly while the sampling 
train is cooling. Capping would create a vacuum and draw liquid out from 
the impingers.
    Before moving the sampling train to the cleanup site, remove the 
probe from the train, wipe off the silicone grease, and cap the open 
outlet of the probe. Be careful not to lose any condensate that might be 
present. Wipe off the silicone grease from the impinger. Use either 
ground-glass stoppers, plastic caps, or serum caps to close these 
openings.
    Transfer the probe and impinger assembly to a cleanup area that is 
clean, protected from the wind, and free of Be contamination.
    Inspect the train before and during this assembly, and note any 
abnormal conditions. Treat the sample as follows:
    Disconnect the probe from the impinger train. Remove the filter and 
any loose particulate matter from the filter holder, and place in a 
sample bottle. Place the contents (measured to 1 ml) of the 
first three impingers into another sample bottle. Rinse the probe and 
all glassware between it and the back half of the third impinger with 
water and acetone, and add this to the latter sample bottle. Clean the 
probe with a brush or a long slender rod and cotton balls. Use acetone 
while cleaning. Add these to the sample bottle. Retain a sample of the 
water and acetone as a blank. The total amount of water and acetone used 
should be measured for accurate blank correction. Place the silica gel 
in the plastic jar. Seal and secure all sample containers for shipment. 
If an additional test is desired, the glassware can be carefully double 
rinsed with water and reassembled. However, if the glassware is out of 
use more than 2 days, repeat the initial acid wash procedure.
    4.3  Analysis.
    4.3.1  Apparatus Preparation. Before use, clean all glassware 
according to the procedure of section 4.1.3. Adjust the instrument 
settings according to the instrument manual, using an absorption 
wavelength of 234.8 nm.
    4.3.2  Sample Preparation. The digestion of Be samples is 
accomplished in part in concentrated HClO4. Caution: The 
analyst must insure that the sample is heated to light brown fumes after 
the initial HNO3 addition; otherwise, dangerous perchlorates 
may result from the subsequent HClO4 digestion. HClO4 
should be used only under a hood.
    4.3.2.1  Filter Preparation. Transfer the filter and any loose 
particulate matter from the sample container to a 150-ml beaker. Add 35 
ml concentrated HNO3. Heat on a hotplate until light brown 
fumes are evident to destroy all organic matter. Cool to room 
temperature, and add 5 ml concentrated H2SO4 and 5 
ml concentrated HClO4. Then proceed with step 4.3.2.4.
    4.3.2.2  Water Preparation. Place a portion of the water and acetone 
sample into a 150-ml beaker, and put on a hotplate. Add portions of the 
remainder as evaporation proceeds and evaporate to dryness. Cool the 
residue, and add 35 ml concentrated HNO3. Heat on a hotplate 
until light brown fumes are evident to destroy any organic matter. Cool 
to room temperature, and add 5 ml concentrated H2SO4 
and 5 ml concentrated HClO4. Then proceed with step 4.3.2.4.
    4.3.2.3  Silica Gel Preparation Analyses. Weigh the spent silica 
gel, and report to the nearest gram.
    4.3.2.4  Final Sample Preparation. Samples from 4.3.2.1 and 4.3.2.2 
may be combined here for ease of analysis. Replace on a hotplate, and 
evaporate to dryness in a HClO4 hood. Cool and dissolve the 
residue in 10.0 ml of 25 percent V/V HCl. Samples are now ready for the 
atomic absorption unit. It is necessary for the Be concentration of the 
sample to be within the calibration range of the unit. If necessary, 
perform further dilution of sample with 25 percent V/V HCl to bring the 
sample within the calibration range.
    4.3.3  Beryllium Determination. Analyze the samples prepared in 
4.3.2 at 234.8 nm using a nitrous oxide/acetylene flame. Aluminum, 
silicon and other elements can interfere with this method if present in 
large quantities. Standard methods are available, however, that may be 
used to effectively eliminate these interferences (see Citation 2 in 
Section 8).

5. Calibration

    5.1  Sampling Train. Calibrate the sampling train components 
according to the procedures outlined in the following sections of

[[Page 237]]

Method 5: Section 5.1 (Probe Nozzle), section 5.2 (Pitot Tube), section 
5.3 (Metering System), section 5.4 (Probe Heater), section 5.5 
(Temperature Gauges), section 5.7 (Barometer). Note that the leak check 
described in section 5.6 of Method 5 applies to this method.

6. Calculations

    6.1  Dry Gas Volume. Using the data from each sample run, calculate 
the dry gas sample volume at standard conditions Vm(std) 
(corrected for leakage, if necessary) as outlined in Section 6.3 of 
Method 5.
    6.2  Volume of Water Vapor in Sample and Moisture Content of Stack 
Gas. Using the data obtained from each sample run, calculate the volume 
of water vapor Vw(std) in the sample, and the moisture 
content Bws of the stack gas. Use Equations 5-2 and 5-3 of 
Method 5.
    6.3 Stack Gas Velocity. Using the data from each sample run and 
Equation 2-9 of Method 2, calculate the average stack gas velocity 
vs(avg).
    6.4  Beryllium Emission Rate. Calculate the Be emission rate R in g/
day for each stack using Equation 104-1. For cyclic operations, use only 
the time per day each stack is in operation. The total Be emission rate 
from a source will be the summation of results from all stacks.

applicable test method. For the purpose of determining compliance with 
an applicable national emission standard, use the average of the results 
of all sample runs.

Method 105--Determination of Mecury in Wastewater Treatment Plant Sewage 
                                 Sludge

1. Applicability and Principle

    1.1  Applicability. This method applies to the determination of 
total organic and inorganic mercury (Hg) content in sewage sludges. The 
range of this method is 0.2 to 5 g/g; it may be extended by 
increasing or decreasing sample size.
    1.2  Principle. Time-composite sludge samples are withdrawn from the 
conveyor belt after dewatering and before incineration or drying. A 
weighed portion of the sludge is digested in aqua regia and oxidized by 
potassium permanganate (KMnO4). Hg in the digested sample is 
then measured by the conventional spectrophotometric cold-vapor 
technique.

daily. Pipet 5.0 ml of the ``Intermediate Mercury Standard Solution'' 
into a 250-ml volumetric flask. Add 20 ml of 15-percent HNO3, 
and adjust the volume to 250 ml with water. Mix thoroughly.
    3.7  Tin (II) Solution, Sodium Chloride-Hydroxylamine Solution, 15-
Percent Nitric Acid, and Potassium Permanganate Solution. Same as Method 
101A, Section 6.2.

4. Procedure

    4.1  Sludge Sampling. Withdraw equal-volume increments of sludge 
[for a total of at least 15 liters (16-qt.)] at intervals of 30 min over 
an 8-hr period, and place in a rigid plastic container.
    4.2  Sludge Mixing. Transfer the entire 15-liter sample to a 57-
liter capacity (2-ft3) mortar mixer. Mix the sample for a 
minimum of 30 min at 30 rpm. Using a 200-ml beaker, take six 100-ml 
portions of sludge, and combine in a 2-liter blender. Blend sludge for 5 
min; add water as necessary to give a fluid consistency. Immediately 
after stopping the blender, use a 50-ml beaker to withdraw four 20-ml 
portions of blended sludge, and place them in separate, tared 125-ml 
Erlenmeyer flasks. Reweigh each flask to determine the exact amount of 
sludge added. (Use three of the samples to determine the mercury content 
in the sludge, and use the fourth to measure the solids content of the 
blended sludge.)
    4.3  Solids Content of Blended Sludge. Dry one of the 20-ml blended 
samples from Section 4.2 in an oven at 105  deg. C to constant weight. 
Cool in a desiccator, and weigh and record the dry weight of the sample.
    4.4  Aqua Regia Digestion of Blended Samples. To each of the three 
remaining 20-ml samples from Section 4.2, add 25 ml of aqua regia, and 
digest the samples on a hot plate at low heat (do not boil) for 30 min, 
or until samples are a pale yellow-brown color and are void of the dark 
brown color characteristic of organic matter. Remove from the hot plate, 
and allow to cool.
    Filter each digested sample separately through an S and S No. 588 
filter, or equivalent, and rinse the filter contents with 50 ml of 
water. Transfer the filtrate and filter washing to a 100-ml volumetric 
flask, and carefully dilute to volume with water.
    4.5  Solids Content of Sludge Before Blending. Using a 200-ml 
beaker, remove two 100-ml portions of mixed sludge from the mortar 
mixer, and place in separate, tared 400-ml beakers. Reweigh each beaker 
to determine the exact amount of sludge added. Dry in an oven at 105 
+ C, and cool in a desiccator to constant weight.
    4.6  Analysis for Mercury. The same as Method 101A, Sections 7.4 and 
8, except for the following variation.
    4.6.1  Spectrophotometer and Recorder Calibration. The mercury 
response may be measured by either peak height or peak area. Note: The 
temperature of the solution affects the rate at which elemental Hg is 
released from solution and, consequently, it affects the shape of the 
absorption curve (area) and the point of maximum absorbance (peak 
height). Therefore, to obtain reproducible results, bring all solutions 
to room temperature before use.
    Set the spectrophotometer wavelength to 253.7 nm. Make certain the 
optical cell is at the minimum temperature that will prevent water 
condensation from occurring. Then set the recorder scale as follows: 
Using a 25-ml graduated cylinder, add 25 ml of water to the aeration-
cell bottle. Add three drops of Antifoam B to the bottle, and then pipet 
5.0 ml of the working Hg standard solution into the aeration cell.
    Note: Always add the Hg containing solution to the aeration cell 
after the 25 ml of water.
    Place a Teflon-coated stirring bar in the bottle. Add 5 ml of 15-
percent HNO3 and 5 ml of 5-percent KMnO4 to the 
aeration bottle, and mix well. Next, attach the bottle section to the 
bubbler section of the aeration cell, and make certain that: (1) the 
exit arm stopcock of the aeration cell (Figure 105-3) is closed (so that 
Hg will not prematurely enter the optical cell when the reducing agent 
is being added), and (2) there is no flow through the bubbler. Add 5 ml 
of sodium chloride-hydroxylamine solution to the aeration bottle through 
the side arm, and mix. If the solution does not become colorless, add 
additional sodium chloride-hydroxylamine solution in 1-ml increments 
until the solution is colorless. Now add 5 ml of tin (II) solution to 
the aeration bottle through the side arm, and immediately stopper the 
side arm. Stir the solution for 15 sec, turn on the recorder, open the 
aeration cell exit arm stopcock, and then immediately initiate aeration 
with continued stirring. Determine the maximum absorbance of the 
standard, and set this value to read 90 percent of the recorder full 
scale.

   Method 106--Determination of Vinyl Chloride From Stationary Sources

Introduction

    Performance of this method should not be attempted by persons 
unfamiliar with the operation of a gas chromatograph (GC) nor by those 
who are unfamiliar with source sampling, because knowledge beyond the 
scope of this presentation is required. Care must be exercised to 
prevent exposure of sampling personnel to vinyl chloride, a carcinogen.

1. Applicability and Principle

    1.1  Applicability. The method is applicable to the measurement of 
vinyl chloride in stack gases from ethylene dichloride, vinyl chloride, 
and polyvinyl chloride manufacturing processes. The method does not 
measure vinyl chloride contained in particulate matter.
    1.2  Principle. An integrated bag sample of stack gas containing 
vinyl chloride (chloroethene) is subjected to GC analysis using a flame 
ionization detector (FID).

2. Range and Sensitivity

    This method is designed for the 0.1 to 50 ppm range. However, common 
GC instruments are capable of detecting 0.02 ppm vinyl chloride. With 
proper calibration, the upper limit may be extended as needed.

3. Interferences

    The chromatographic columns and the corresponding operating 
parameters herein described normally provide an adequate resolution of 
vinyl chloride; however, resolution interferences may be encountered on 
some sources. Therefore, the chromatograph operator shall select the 
column and operating parameters best suited to his particular

[[Page 240]]

analysis requirements, subject to the approval of the Administrator. 
Approval is automatic, provided that the tester produces confirming data 
through an adequate supplemental analytical technique, such as analysis 
with a different column or GC/mass spectroscopy, and has the data 
available for review by the Administrator.

4. Apparatus

    4.1  Sampling (see Figure 106-1). The sampling train consists of the 
following components:
    4.1.1  Probe. Stainless steel, Pyrex glass, or Teflon tubing (as 
stack temperature permits) equipped with a glass wool plug to remove 
particulate matter.
    4.1.2  Sample Lines. Teflon, 6.4-mm outside diameter, of sufficient 
length to connect probe to bag. Use a new unused piece for each series 
of bag samples that constitutes an emission test, and discard upon 
completion of the test.
    4.1.3  Quick Connects. Stainless steel, male (2) and female (2), 
with ball checks (one pair without), located as shown in Figure 106-1.
    4.1.4  Tedlar Bags. 50- to 100-liter capacity, to contain sample. 
Aluminized Mylar bags may be used if the samples are analyzed within 24 
hours of collection.
    4.1.5  Bag Containers. Rigid leak-proof containers for sample bags, 
with covering to protect contents from sunlight.
    4.1.6  Needle Valve. To adjust sample flow rates.
    4.1.7  Pump. Leak-free, with minimum of 2-liter/min capacity.
    4.1.8  Charcoal Tube. To prevent admission of vinyl chloride and

5. Reagents


[[Page 241]]


    Use only reagents that are of chromatograph grade.
    5.1  Analysis. The following are required for analysis.
    5.1.1  Helium or Nitrogen. Zero grade, for chromatographic carrier 
gas.
    5.1.2  Hydrogen. Zero grade.
    5.1.3  Oxygen or Air. Zero grade, as required by the detector.
    5.2  Calibration. Use one of the following options: either 5.2.1 and 
5.2.2, or 5.2.3.
    5.2.1  Vinyl Chloride. Pure vinyl chloride gas certified by the 
manufacturer to contain a minimum of 99.9 percent vinyl chloride, for 
use in the preparation of standard gas mixtures in Section 7.1. If the 
gas manufacturer maintains a bulk cylinder supply of 99.9+ percent vinyl 
chloride, the certification analysis may have been performed on this 
supply rather than on each gas cylinder prepared from this bulk supply. 
The date of gas cylinder preparation and the certified analysis must 
have been affixed to the cylinder before shipment from the gas 
manufacturer to the buyer.
    5.2.2  Nitrogen. Zero grade, for preparation of standard gas 
mixtures as described in Section 7.1.
    5.2.3  Cylinder Standards (3). Gas mixture standards (50-, 10-, and 
5-ppm vinyl chloride in nitrogen cylinders). The tester may use cylinder 
standards to directly prepare a chromatograph calibration curve as 
described in Section 7.2.2, if the following conditions are met: (a) The 
manufacturer certifies the gas composition with an accuracy of 
plus-minus3 percent or better (see Section 5.2.3.1). (b) The 
manufacturer recommends a maximum shelf life over which the gas 
concentration does not change by greater than plus-minus5 
percent from the certified value. (c) The manufacturer affixes the date 
of gas cylinder preparation, certified vinyl chloride concentration, and 
recommended maximum shelf life to the cylinder before shipment to the 
buyer.
    5.2.3.1  Cylinder Standards Certification. The manufacturer shall 
certify the concentration of vinyl chloride in nitrogen in each cylinder 
by (a) directly analyzing each cylinder and (b) calibrating his 
analytical procedure on the day of cylinder analysis. To calibrate his 
analytical procedure, the manufacturer shall use, as a minimum, a three-
point calibration curve. It is recommended that the manufacturer 
maintain (1) a high-concentration calibration standard (between 50 and 
100 ppm) to prepare his calibration curve by an appropriate dilution 
technique and (2) a low-concentration calibration standard (between 5 
and 10 ppm) to verify the dilution technique used. If the difference 
between the apparent concentration read from the calibration curve and 
the true concentration assigned to the low-concentration calibration 
standard exceeds 5 percent of the true concentration, the manufacturer 
shall determine the source of error and correct it, then repeat the 
three-point calibration.
    5.2.3.2  Verification of Manufacturer's Calibration Standards. 
Before using a standard, the manufacturer shall verify each calibration 
standard (a) by comparing it to gas mixtures prepared (with 99 mole 
percent vinyl chloride) in accordance with the procedure described in 
Section 7.1 or (b) calibrating it against vinyl chloride cylinder 
Standard Reference Materials (SRM's) prepared by the National Bureau of 
Standards, if such SRM's are available. The agreement between the 
initially determined concentration value and the verification 
concentration value must be within plus-minus5 percent. The 
manufacturer must reverify all calibration standards on a time interval 
consistent with the shelf life of the cylinder standards sold.
    5.2.4  Audit Cylinder Standards (2). Gas mixture standards with 
concentrations known only to the person supervising the analysis of 
samples. The audit cylinder standards shall be identically prepared as 
those in Section 5.2.3 (vinyl chloride in nitrogen cylinders). The 
concentrations of the audit cylinder should be: one low-concentration 
cylinder in the range of 5 to 20 ppm vinyl chloride and one high-
concentration cylinder in the range of 20 to 50 ppm. When available, the 
tester may obtain audit cylinders by contacting: Environmental 
Protection Agency, Environmental Monitoring Systems Laboratory, Quality 
Assurance Division (MD-77), Research Triangle Park, North Carolina 
27711. Audit cylinders obtained from a commercial gas manufacturer may 
be used provided: (a) the gas manufacturer certifies the audit cylinder 
as described in Section 5.2.3.1, and (b) the gas manufacturer obtains an 
independent analysis of the audit cylinders to verify this analysis. 
Independent analysis is defined here to mean analysis performed by an 
individual different than the individual who performs the gas 
manufacturer's analysis, while using calibration standards and analysis 
equipment different from those used for the gas manufacturer's analysis. 
Verification is complete and acceptable when the independent analysis 
concentration is within 5 percent of the gas manufacturer's 
concentration.

6. Procedure

    6.1  Sampling. Assemble the sample train as shown in Figure 106-1. A 
bag leak check should have been performed previously according to 
Section 7.3.2. Join the quick connects as illustrated, and determine 
that all connection between the bag and the probe are tight. Place the 
end of the probe at the centroid of the stack and start the pump with 
the needle valve adjusted to yield a flow that will fill over 50 percent 
of bag volume in the specific sample period. After allowing sufficient 
time to purge the line several

[[Page 242]]

times, change the vacuum line from the container to the bag and evacuate 
the bag until the rotameter indicates no flow. Then reposition the 
sample and vacuum lines and begin the actual sampling, keeping the rate 
proportional to the stack velocity. At all times, direct the gas exiting 
the rotameter away from sampling personnel. At the end of the sample 
period, shut off the pump, disconnect the sample line from the bag, and 
disconnect the vacuum line from the bag container. Protect the bag 
container from sunlight.
    6.2  Sample Storage. Keep the sample bags out of direct sunlight. 
When at all possible, analysis is to be performed within 24 hours, but 
in no case in excess of 72 hours of sample collection. Aluminized Mylar 
bag samples must be analyzed within 24 hours.
    6.3  Sample Recovery. With a new piece of Teflon tubing identified 
for that bag, connect a bag inlet valve to the gas chromatograph sample 
valve. Switch the valve to receive gas from the bag through the sample 
loop. Arrange the equipment so the sample gas passes from the sample 
valve to 100-ml/min rotameter with flow control valve followed by a 
charcoal tube and a 1-in. H2 O pressure gauge. The tester may 
maintain the sample flow either by a vacuum pump or container 
pressurization if the collection bag remains in the rigid container. 
After sample loop purging is ceased, allow the pressure gauge to return 
to zero before activating the gas sampling valve.
    6.4  Analysis. Set the column temperature to 100  deg.C and the 
detector temperature to 150  deg.C. When optimum hydrogen and oxygen 
flow rates have been determined, verify and maintain these flow rates 
during all chromatography operations. Using zero helium or nitrogen as 
the carrier gas, establish a flow rate in the range consistent with the 
manufacturer's requirements for satisfactory detector operation. A flow 
rate of approximately 40 ml/min should produce adequate separations. 
Observe the base line periodically and determine that the noise level 
has stabilized and that base line drift has ceased. Purge the sample 
loop for 30 seconds at the rate of 100 ml/min, shut off flow, allow the 
sample loop pressure to reach atmospheric pressure as indicated by the 
H2 O manometer, then activate the sample valve. Record the 
injection time (the position of the pen on the chart at the time of 
sample injection), sample number, sample loop temperature, column 
temperature, carrier gas flow rate, chart speed, and attenuator setting. 
Record the barometric pressure. From the chart, note the peak having the 
retention time corresponding to vinyl chloride as determined in Section 
7.2.1. Measure the vinyl chloride peak area, Am, by use of a 
disc integrator, electronic integrator, or a planimeter. Measure and 
record the peak heights, Hm. Record Am and 
retention time. Repeat the injection at least two times or until two 
consecutive values for the total area of the vinyl chloride peak do not 
vary more than 5 percent. Use the average value for these two total 
areas to compute the bag concentration.
    Compare the ratio of Hm to Am for the vinyl 
chloride sample with the same ratio for the standard peak that is 
closest in height. If these ratios differ by more than 10 percent, the 
vinyl chloride peak may not be pure (possibly acetaldehyde is present) 
and the secondary column should be employed (see Section 4.3.2.2).
    6.5  Determination of Bag Water Vapor Content. Measure the ambient 
temperature and barometric pressure near the bag. From a water 
saturation vapor pressure table, determine and record the water vapor 
content of the bag as a decimal figure. (Assume the relative humidity to 
be 100 percent unless a lesser value is known.)

7. Preparation of Standard Gas Mixtures, Calibration, and Quality 
Assurance

    7.1  Preparation of Vinyl Chloride Standard Gas Mixtures. (Optional 
Procedure--delete if cylinder standards are used.) Evacuate a 16-inch 
square Tedlar bag that has passed a leak check (described in Section 
7.3.2) and meter in 5.0 liters of nitrogen. While the bag is filling, 
use the 0.5-ml syringe to inject 250 l of 99.9+ percent vinyl 
chloride gas through the wall of the bag. Upon withdrawing the syringe, 
immediately cover the resulting hole with a piece of adhesive tape. The 
bag now contains a vinyl chloride concentration of 50 ppm. In a like 
manner use the 50 l syringe to prepare gas mixtures having 10- 
and 5-ppm vinyl chloride concentrations. Place each bag on a smooth 
surface and alternately depress opposite sides of the bag 50 times to 
further mix the gases. These gas mixture standards may be used for 10 
days from the date of preparation, after which time new gas mixtures 
must be prepared. (Caution: Contamination may be a problem when a bag is 
reused if the new gas mixture standard is a lower concentration than the 
previous gas mixture standard.)
    7.2  Calibration.
    7.2.1  Determination of Vinyl Chloride Retention Time. (This section 
can be performed simultaneously with Section 7.2.2.) Establish 
chromatograph conditions identical with those in Section 6.4 above. 
Determine proper attenuator position. Flush the sampling loop with zero 
helium or nitrogen and activate the sample valve. Record the injection 
time, sample loop temperature, column temperature, carrier gas flow 
rate, chart speed, and attenuator setting. Record peaks and detector 
responses that occur in the absence of vinyl chloride. Maintain 
conditions with the equipment plumbing arranged identically to Section 
6.3, and flush the sample loop for 30 seconds at the rate of 100 ml/min 
with one of the vinyl chloride calibration mixtures. Then activate the 
sample valve. Record the

[[Page 243]]

injection time. Select the peak that corresponds to vinyl chloride. 
Measure the distance on the chart from the injection time to the time at 
which the peak maximum occurs. This quantity divided by the chart speed 
is defined as the retention time. Since other organics may be present in 
the sample, positive identification of the vinyl chloride peak must be 
made.
    7.2.2  Preparation of Chromatograph Calibration Curve. Make a GC 
measurement of each gas mixture standard (described in Section 5.2.3 or 
7.1) using conditions identical with those listed in Sections 6.3 and 
6.4. Flush the sampling loop for 30 seconds at the rate of 100 ml/min 
with one of the standard mixtures, and activate the sample valve. Record 
the concentration of vinyl chloride injected (Cc), attenuator 
setting, chart speed, peak area, sample loop temperature, column 
temperature, carrier gas flow rate, and retention time. Record the 
barometric pressure. Calculate Ac, the peak area multiplied 
by the attenuator setting. Repeat until two consecutive injection areas 
are within 5 percent, then plot the average of those two values versus 
Cc. When the other standard gas mixtures have been similarly 
analyzed and plotted, draw a straight line through the points derived by 
the least squares method. Perform calibration daily, or before and after 
the analysis of each emission test set of bag samples, whichever is more 
frequent. For each group of sample analyses, use the average of the two 
calibration curves which bracket that group to determine the respective 
sample concentrations. If the two calibration curves differ by more than 
5 percent from their mean value, then report the final results by both 
calibration curves.
    7.3  Quality Assurance.
    7.3.1  Analysis Audit. Immediately after the preparation of the 
calibration curve and prior to the sample analyses, perform the analysis 
audit described in Appendix C, Procedure 2: ``Procedure for Field 
Auditing GC Analysis.''
    7.3.2  Bag Leak Checks. Checking of bags for leaks is required after 
bag use and strongly recommended before bag use. After each use, connect 
a water manometer and pressurize the bag to 5 to 10 cm H2 O 
(2 to 4 in. H2 O). Allow to stand for 10 min. Any 
displacement in the water manometer indicates a leak. Also, check the 
rigid container for leaks in this manner. (Note: An alternative leak 
check method is to pressurize the bag to 5 to 10 cm H2 O and 
allow it to stand overnight. A deflated bag indicates a leak.) For each 
sample bag in its rigid container, place a rotameter in line between the 
bag and the pump inlet. Evacuate the bag. Failure of the rotameter to 
register zero flow when the bag appears to be empty indicates a leak.

    Method 107--Determination of Vinyl Chloride Content of Inprocess 
  Wastewater Samples, and Vinyl Chloride Content of Polyvinyl Chloride 
               Resin, Slurry, Wet Cake, and Latex Samples

Introduction

    Performance of this method should not be attempted by persons 
unfamiliar with the operation of a gas chromatograph (GC), nor by those 
who are unfamiliar with source sampling, because knowledge beyond the 
scope of this presentation is required. Care must be exercised to 
prevent exposure of sampling personnel to vinyl chloride, a carcinogen.

1. Applicability and Principle

    1.1 Applicability. This method applies to the measurement of the 
vinyl chloride monomer (VCM) content of inprocess wastewater samples, 
and the residual vinyl chloride monomer (RVCM) content of polyvinyl 
chloride (PVC) resins, wet cake, slurry, and latex samples. It cannot be 
used for polymer in fused forms, such as sheet or cubes. This method is 
not acceptable where methods from Section 304(h) of the Clean Water Act, 
33 U.S.C. 1251 et seq. (the Federal Water Pollution Control Amendments 
of 1972 as amended by the Clean Water Act of 1977) are required.
    1.2 Principle. The basis for this method relates to the vapor 
equilibrium that is established at a constant known temperature in a 
closed system between RVCM, PVC resin, water, and air. The RVCM in a PVC 
resin will equilibrate rapidly in a closed vessel, provided that the 
temperature of the PVC resin is maintained above the glass transition 
temperature of that specific resin.

2. Range and Sensitivity

    The lower limit of detection of vinyl chloride will vary according 
to the sampling and chromatographic system. The system should be capable 
of producing a measurement for a 50-ppm vinyl chloride standard that is 
at least 10 times the standard deviation of the system background noise 
level.

3. Interferences

    The chromatograph columns and the corresponding operating parameters 
herein described normally provide an adequate resolution of vinyl 
chloride; however, resolution interferences may be encountered on some 
sources. Therefore, the chromatograph operator shall select the column 
and operating parameters best suited to his particular analysis 
requirements, subject to the approval of the Administrator. Approval is 
automatic provided that the tester produces confirming data through an 
adequate supplemental analytical technique, such as analysis with a 
different column or GC/mass spectroscopy, and has the data available for 
review by the Administrator.

4. Precision and Reproducibility

    An interlaboratory comparison between seven laboratories of three 
resin samples, each split into three parts, yielded a standard deviation 
of 2.63 percent for a sample with a mean of 2.09 ppm, 4.16 percent for a 
sample with a mean of 1.66 ppm, and 5.29 percent for a sample with a 
mean of 62.66 ppm.

5. Safety

    Do not release vinyl chloride to the laboratory atmosphere during 
preparation of standards. Venting or purging with VCM/air mixtures must 
be held to a minimum. When they are required, the vapor must be routed 
to outside air. Vinyl chloride, even at low ppm levels, must never be 
vented inside the laboratory. After vials have been analyzed, the gas 
must be vented prior to removal of the vial from the instrument 
turntable. Vials must be vented through a hypodermic needle connected to 
an activated charcoal tube to prevent release of vinyl chloride into the 
laboratory atmosphere. The charcoal must be replaced prior to vinyl 
chloride breakthrough.

6. Apparatus

deg.C. The chromatograph shall be equipped with a flame ionization 
detector. Perkin-Elmer Corporation Models F-40, F-42, F-45, HS-6, and 
HS-100, and Hewlett-Packard Corporation Model 19395A have been found 
satisfactory. Chromatograph backflush capability may be required.

confirming that there is adequate resolution of the vinyl chloride peak. 
(Adequate resolution is defined as an area overlap of not more than 10 
percent of the vinyl chloride peak by an interferent peak. Calculation 
of area overlap is explained in Appendix C, Procedure 1: ``Determination 
of Adequate Chromatographic Peak Resolution.'') Two 1.83 m columns, each

7. Reagents

    Use only reagents that are of chromatographic grade.
    7.1  Analysis. The following items are required for analysis:
    7.1.1  Hydrogen. Zero grade.
    7.1.2  Nitrogen or Helium. Zero grade.
    7.1.3  Air. Zero grade.
    7.1.4  Water. Interference free.
    7.2  Calibration. The following items are required for calibration:
    7.2.1  Cylinder Standards (4). Gas mixture standards (50-, 500-, 
2000- and 4000-ppm vinyl chloride in nitrogen cylinders). The tester may 
use cylinder standards to directly prepare a chromatograph calibration 
curve as described in Section 9.2, if the following conditions are met: 
(a) The manufacturer certifies the gas composition with an accuracy of 
plus-minus3 percent or better (see Section 7.2.1.1). (b) The 
manufacturer recommends a maximum shelf life over which the gas 
concentration does not change by greater than plus-minus5 
percent from the certified value. (c) The manufacturer affixes the date 
of gas cylinder preparation, certified vinyl chloride concentration, and 
recommended maximum shelf life to the cylinder before shipment to the 
buyer.
    7.2.1.1  Cylinder Standards Certification. The manufacturer shall 
certify the concentration of vinyl chloride in nitrogen in each cylinder 
by (a) directly analyzing each cylinder and (b) calibrating his 
analytical procedure on the day of cylinder analysis. To calibrate his 
analytical procedure, the manufacturer shall use, as a minimum, a 3-
point calibration curve. It is recommended that the manufacturer 
maintain (1) a high-concentration calibration standard (between 4000 and 
8000 ppm) to prepare his calibration curve by an appropriate dilution 
technique and (2) a low-concentration calibration standard (between 50 
and 500 ppm) to verify the dilution technique used. If the difference 
between the apparent concentration read from the calibration curve and 
the true concentration assigned to the low-concentration calibration 
standard exceeds 5 percent of the true concentration, the manufacturer 
shall determine the source of error and correct it, then repeat the 3-
point calibration.
    7.2.1.2  Verification of Manufacturer's Calibration Standards. 
Before using, the manufacturer shall verify each calibration standard by 
(a) comparing it to gas mixtures prepared (with 99 mole percent vinyl 
chloride) in accordance with the procedure described in Section 7.1 of 
Method 106 or by (b) calibrating it against vinyl chloride cylinder 
Standard Reference Materials (SRM's) prepared by the National Bureau of 
Standards, if such SRM's are available. The agreement between the 
initially determined concentration value and the verification 
concentration value must be within 5 percent. The manufacturer must 
reverify all calibration standards on a time interval consistent with 
the shelf life of the cylinder standards sold.

8. Procedure

    8.1  Sampling.
    8.1.1  PVC Sampling. Allow the resin or slurry to flow from a tap on 
the tank or silo until the tap line has been well purged. Extend and 
fill a 60-ml sample bottle under the tap, and immediately tighten a cap 
on the bottle. Wrap adhesive tape around the cap and bottle to prevent 
the cap from loosening. Place an identifying label on each bottle, and 
record the date, time, and sample location both on the bottles and in a 
log book. All samples should be kept refrigerated.
    8.1.2  Water Sampling. At the sampling location fill the vials 
bubble-free to overflowing so that a convex meniscus forms at the top. 
The excess water is displaced as the sealing disc is carefully placed, 
with the Teflon side down, on the opening of the vial.
    Place the aluminum seal over the disc and the neck of the vial, and 
crimp into place. Affix an identifying label on the bottle, and record 
the date, time, and sample location both on the vials and in a log book. 
All samples must be kept refrigerated until analyzed.
    8.2  Sample Recovery. Samples must be run within 24 hours.
    8.2.1  Resin Samples. The weight of the resin used must be between 
0.1 and 4.5 grams. An exact weight must be obtained (1 
percent) for each sample. In the case of suspension resins, a volumetric 
cup can be prepared for holding the required amount of sample. When the 
cup is used, open the sample bottle, and add the cup volume of resin to 
the tared sample vial (tared, including septum

[[Page 247]]

and aluminum cap). Obtain the exact sample weight, add 100 l or 
about two equal drops of water, and immediately seal the vial. Report 
this value on the data sheet; it is required for calculation of RVCM. In 
the case of dispersion resins, the cup cannot be used. Weigh the sample 
in an aluminum dish, transfer the sample to the tared vial, and 
accurately weigh it in the vial. After prepressurization of the samples, 
condition them for a minimum of 1 hour in the 90  deg.C bath. Do not 
exceed 5 hours.
    Prepressurization is not required if the sample weight, as analyzed, 
does not exceed 0.2 gram. It is also not required if solution of the 
prepressurization equation yields an absolute prepressurization value 
that is within 30 percent of the atmospheric pressure.
    Note: Some aluminum vial caps have a center section that must be 
removed prior to placing into sample tray. If the cap is not removed, 
the injection needle will be damaged.
    8.2.2  Suspension Resin Slurry and Wet Cake Samples. Decant the 
water from a wet cake sample, and turn the sample bottle upside down 
onto a paper towel. Wait for the water to drain, place approximately 0.2 
to 4.0 grams of the wet cake sample in a tared vial (tared, including 
septum and aluminum cap) and seal immediately. Then determine the sample 
weight (1 percent). All samples, weighing over 0.2 gram, 
must be prepressurized prior to conditioning for 1 hour at 90  deg.C, 
except as noted in Section 8.2.1. A sample of wet cake is used to 
determine total solids (TS). This is required for calculating the RVCM.
    8.2.3  Dispersion Resin Slurry and Geon Latex Samples. The materials 
should not be filtered. Sample must be thoroughly mixed. Using a tared 
vial (tared, including septum and aluminum cap) add approximately eight 
drops (0.25 to 0.35 g) of slurry or latex using a medicine dropper. This 
should be done immediately after mixing. Seal the vial as soon as 
possible. Determine sample weight (1 percent). Condition the 
vial for 1 hour at 90  deg.C in the analyzer bath. Determine the TS on 
the slurry sample (Section 8.3.5).
    8.2.4  Inprocess Wastewater Samples. Using a tared vial (tared, 
including septum and aluminum cap) quickly add approximately 1 cc of 
water using a medicine dropper. Seal the vial as soon as possible. 
Determine sample weight (1 percent). Condition the vial for 
1 hour at 90  deg.C in the analyzer bath.
    8.3  Analysis.
    8.3.1  Preparation of Equipment. Install the chromatographic column 
and condition overnight at 160  deg.C. In the first operation, Porapak 
columns must be purged for 1 hour at 230  deg.C.
    Do not connect the exit end of the column to the detector while 
conditioning. Hydrogen and air to the detector must be turned off while 
the column is disconnected.
    8.3.1.1  Flow Rate Adjustments. Adjust flow rates as follows:
    a. Nitrogen Carrier Gas. Set regulator on cylinder to read 50 psig. 
Set regulator on chromatograph to produce a flow rate of 30.0 cc/min. 
Accurately measure the flow rate at the exit end of the column using the 
soap film flowmeter and a stopwatch, with the oven and column at the 
analysis temperature. After the instrument program advances to the ``B'' 
(backflush) mode, adjust the nitrogen pressure regulator to exactly 
balance the nitrogen flow rate at the detector as was obtained in the 
``A'' mode.
    b. Vial Prepressurizer Nitrogen. After the nitrogen carrier is set, 
solve the following equation and adjust the pressure on the vial 
prepressurizer accordingly.


Where:

T1=Ambient temperature,  deg.K.
T2=Conditioning bath temperature,  deg.K.
P1=Gas chromatograph absolute dosing pressure (analysis 
          mode), k Pa.
Pw1=Water vapor pressure @ 90  deg.C (525.8 mm Hg).
Pw2=Water vapor pressure @ 22  deg.C (19.8 mm Hg).
7.50=mm Hg per k Pa.
10 k Pa=Factor to adjust the prepressurized pressure to slightly less 
          than the dosing pressure.

    Because of gauge errors, the apparatus may over-pressurize the vial. 
If the vial pressure is at or higher than the dosing pressure, an 
audible double injection will occur. If the vial pressure is too low, 
errors will occur on resin samples because of inadequate time for head-
space gas equilibrium. This condition can be avoided by running several 
standard gas samples at various pressures around the calculated 
pressure, and then selecting the highest pressure that does not produce 
a double injection. All samples and standards must be pressurized for 60 
seconds using the vial prepressurizer. The vial is then placed into the 
90  deg.C conditioning bath and tested for leakage by placing a drop of 
water on the septum at the needle hole. A clean, burr-free needle is 
mandatory.
    c. Burner Air Supply. Set regulator on cylinder to read 50 psig. Set 
regulator on chromatograph to supply air to burner at a rate between 250 
and 300 cc/min. Check with bubble flowmeter.
    d. Hydrogen Supply. Set regulator on cylinder to read 30 psig. Set 
regulator on chromatograph to supply approximately 35  5 cc/
min. Optimize hydrogen flow to yield the most sensitive detector 
response without extinguishing the flame. Check flow with bubble meter 
and record this flow.

[[Page 248]]

    8.3.1.2  Temperature Adjustments. Set temperatures as follows:
    a. Oven (chromatograph column), 140  deg.C.
    b. Dosing Line, 150  deg.C.
    c. Injection Block, 170  deg.C.
    d. Sample Chamber, Water Temperature, 90  deg.C  1.0 
deg.C.
    8.3.1.3  Ignition of Flame Ionization Detector. Ignite the detector 
according to the manufacturer's instructions.
    8.3.1.4  Amplifier Balance. Balance the amplifier according to the 
manufacturer's instructions.
    8.3.2  Programming the Chromatograph. Program the chromatograph as 
follows:
    a. I--Dosing or Injection Time. The normal setting is 2 seconds.
    b. A--``Analysis Time.'' The normal setting is approximately 70 
percent of the VCM retention time. When this timer terminates, the 
programmer initiates backflushing of the first column.
    c. B--Backflushing Time. The normal setting is double the ``analysis 
time.''
    d. W--Stabilization Time. The normal setting is 0.5 min to 1.0 min.
    e. X--Number of Analyses Per Sample. The normal setting is one.
    8.3.3  Preparation of Sample Turntable. Before placing any sample 
into turntable, be certain that the center section of the aluminum cap 
has been removed. The numbered sample vials should be placed in the 
corresponding numbered positions in the turntable. Insert samples in the 
following order:
    Position 1 and 2--Old 2000-ppm standards for conditioning. These are 
necessary only after the analyzer has not been used for 24 hours or 
longer.
    Position 3--50-ppm standard, freshly prepared.
    Position 4--500-ppm standard, freshly prepared.
    Position 5--2000-ppm standard, freshly prepared.
    Position 6--4000-ppm standard, freshly prepared.
    Position 7--Sample No. 7 (This is the first sample of the day, but 
is given as 7 to be consistent with the turntable and the integrator 
printout.)
    After all samples have been positioned, insert the second set of 50-
, 500-, 2000-, and 4000-ppm standards. Samples, including standards, 
must be conditioned in the bath of 90  deg.C for 1 hour (not to exceed 5 
hours).
    8.3.4  Start Chromatograph Program. When all samples, including 
standards, have been conditioned at 90  deg.C for 1 hour, start the 
analysis program according to the manufacturer's instructions. These 
instructions must be carefully followed when starting and stopping a 
program to prevent damage to the dosing assembly.
    8.3.5  Determination of TS. For wet cake, slurry, resin solution, 
and PVC latex samples, determine TS for each sample by accurately 
weighing approximately 3 to 4 grams of sample in an aluminum pan before 
and after placing in a draft oven (105 to 110  deg.C). Samples must be 
dried to constant weight. After first weighing, return the pan to the 
oven for a short period of time, and then reweigh to verify complete 
dryness. The TS are then calculated as the final sample weight divided 
by initial sample weight.

9. Calibration

    Calibration is to be performed each 8-hour period the chromatograph 
is used. Alternatively, calibration with duplicate 50-, 500-, 2,000-, 
and 4,000-ppm standards (hereafter described as a four-point 
calibration) may be performed on a monthly basis, provided that a 
calibration confirmation test consisting of duplicate analyses of an 
appropriate standard is performed once per plant shift, or once per 
chromatograph carrousel operation (if the chromatograph operation is 
less frequent than once per shift). The criterion for acceptance of each 
calibration confirmation test is that both analyses of 500-ppm standards 
[2,000-ppm standards if dispersion resin (excluding latex resin) samples 
are being analyzed] must be within 5 percent of the most recent four-
point calibration curve. If this criterion is not met, then a complete 
four-point calibration must be performed before sample analyses can 
proceed.
    9.1  Preparation of Standards. Calibration standards are prepared as 
follows: Place 100l or about two equal drops of distilled water 
in the sample vial, then fill the vial with the VCM/nitrogen standard, 
rapidly seat the septum, and seal with the aluminum cap. Use a \1/8\-in. 
stainless steel line from the cylinder to the vial. Do not use rubber or 
Tygon tubing. The sample line from the cylinder must be purged (into a 
properly vented hood) for several minutes prior to filling the vials. 
After purging, reduce the flow rate to 500 to 1000 cc/min. Place end of 
tubing into vial (near bottom). Position a septum on top of the vial, 
pressing it against the \1/8\-in. filling tube to minimize the size of 
the vent opening. This is necessary to mimimize mixing air with the 
standard in the vial. Each vial is to be purged with standard for 90 
seconds, during which time the filling tube is gradually slid to the top 
of the vial. After the 90 seconds, the tube is removed with the septum, 
simultaneously sealing the vial. Practice will be necessary to develop 
good technique. Rubber gloves should be worn during the above 
operations. The sealed vial must then be pressurized for 60 seconds 
using the vial prepressurizer. Test the vial for leakage by placing a 
drop of water on the septum at the needle hole. Prepressurization of 
standards is not required unless samples have been prepressurized.
    9.2  Preparation of Chromatograph Calibration Curve.

[[Page 249]]

    Prepare two vials each of 50-, 500-, 2,000-, and 4,000-ppm 
standards. Run the calibration samples in exactly the same manner as 
regular samples. Plot As, the integrator area counts for each 
standard sample, versus Cc, the concentration of vinyl 
chloride in each standard sample. Draw a straight line through the 
points derived by the least squares method.

10. Calculations

    10.1  Response Factor. If the calibration curve described in Section 
9.2 passes through zero, an average response factor, Rf, may 
be used to facilitate computation of vinyl chloride sample 
concentrations.
    To compute Rf, first compute a response factor, 
Rs, for each sample as follows:
[GRAPHIC] [TIFF OMITTED] TC15NO91.072

where:

Rs=Response factor, area counts/ppm.
As=Chromatogram area counts of vinyl chloride for the sample, 
          area counts.
Cc=Concentration of vinyl chloride in the standard sample, 
          ppm.

    Sum the individual response factors, and calculate Rf. If 
the calibration curve does not pass through zero, use the calibration 
curve to determine each sample concentration.
    10.2  Residual Vinyl Chloride Monomer Concentration, 
(Crvc) or Vinyl Chloride Monomer Concentration. Calculate 
Crvc in ppm or mg/kg as follows:


Where:

As=Chromatogram area counts of vinyl chloride for the sample.
Pa=Ambient atmospheric pressure, mm Hg.
Rf=Response factor in area counts per ppm VCM.
Tl=Ambient laboratory temperature,  deg.K.
Mv=Molecular weight of VCM, 62.5 g/mole.
Vg=Volume of vapor phase, cm3.
[GRAPHIC] [TIFF OMITTED] TC15NO91.073

R=Gas constant, (62360 cm\3\) (mm Hg)/(mole)( deg. K).

m=Sample weight, g.
Kp=Henry's Law Constant for VCM in PVC @ 90  deg.C, 
          6.52 x 10-6 g/g/mm Hg.
TS=Total solids expressed as a decimal fraction.
T2=Equilibrium temperature,  deg.K.
Kw=Henry's Law Constant for VCM in water @ 90  deg.C, 
          7 x 10-7 g/g/mm Hg.
Vv=Vial volume, cm\3\.
1.36=Density of PVC at 90 deg. C, g/cm\3\.
0.9653=Density of water at 90 deg. C, g/cm\3\.
[GRAPHIC] [TIFF OMITTED] TC15NO91.074

    Results calculated using these equations represent concentration 
based on the total sample. To obtain results based on dry PVC content, 
divide by TS.

Method 107A--Determination of Vinyl Chloride Content of Solvents, Resin-
Solvent Solution, Polyvinyl Chloride Resin, Resin Slurry, Wet Resin, and 
                              Latex Samples

Introduction

    Performance of this method should not be attempted by persons 
unfamiliar with the operation of a gas chromatograph (GC) or by those 
who are unfamiliar with source sampling because knowledge beyond the 
scope of this presentation is required. Care must be

[[Page 250]]

exercised to prevent exposure of sampling personnel to vinyl chloride, a 
carcinogen.

1. Applicability and Principle

    1.1  Applicability. This is an alternative method and applies to the 
measurement of the vinyl chloride content of solvents, resin solvent 
solutions, polyvinyl chloride (PVC) resin, wet cake slurries, latex, and 
fabricated resin samples. This method is not acceptable where methods 
from Section 304(h) of the Clean Water Act, 33 U.S.C. 1251 et seq., (the 
Federal Water Pollution Control Act Amendments of 1972 as amended by the 
Clean Water Act of 1977) are required.
    1.2  Principle. The basis for this method lies in the direct 
injection of a liquid sample into a chromatograph and the subsequent 
evaporation of all volatile material into the carrier gas stream of the 
chromatograph, thus permitting analysis of all volatile material 
including vinyl chloride.

2. Range and Sensitivity

    The lower limit of detection of vinyl chloride in dry PVC resin is 
0.2 ppm. For resin solutions, latexes, and wet resin, this limit rises 
inversely as the nonvolatile (resin) content decreases.
    With proper calibration, the upper limit may be extended as needed.

3. Interferences

    The chromatograph columns and the corresponding operating parameters 
herein described normally provide an adequate resolution of vinyl 
chloride. In cases where resolution interferences are encountered, the 
chromatograph operator shall select the column and operating parameters 
best suited to his particular analysis problem, subject to the approval 
of the Administrator. Approval is automatic, provided that the tester 
produces confirming data through an adequate supplemental analytical 
technique, such as analysis with a different column or GC/mass 
spectroscopy, and has the data available for review by the 
Administrator.

4. Precision and Reproducibility

    A standard sample of latex containing 181.8 ppm vinyl chloride 
analyzed 10 times by the alternative method showed a standard deviation 
of 7.5 percent and a mean error of 0.21 percent.
    A sample of vinyl chloride copolymer resin solution was analyzed 10 
times by the alternative method and showed a standard deviation of 6.6 
percent at a level of 35 ppm.

5. Safety

    Do not release vinyl chloride to the laboratory atmosphere during 
preparation of standards. Venting or purging with vinyl chloride monomer 
(VCM) air mixtures must be held to minimum. When purging is required, 
the vapor must be routed to outside air. Vinyl chloride, even at low-ppm 
levels, must never be vented inside the laboratory.

glass sparger to attempt to remove the interfering peak. Reanalyze the 
sparged THF to determine whether the THF is acceptable for use. If the 
scan is comparable to B, the THF should be acceptable for use in the 
analysis.

8. Procedure

    8.1  Sampling. Allow the liquid or dried resin to flow from a tap on 
the tank, silo, or pipeline until the tap has been purged. Fill a wide-
mouth pint bottle, and immediately tightly cap the bottle. Place an 
identifying label on each bottle and record the date, time, sample 
location, and material.
    8.2  Sample Treatment. Sample must be run within 24 hours.
    8.2.1  Resin Samples. Weigh 9.00 plus-minus 0.01 g of THF 
or DMAC in a tared 20-ml vial. Add 1.00 plus-minus 0.01 g of 
resin to the tared vial containing the THF or DMAC. Close the vial 
tightly with the screw cap, and shake or otherwise agitate the vial 
until complete solution of the resin is obtained. Shaking may require 
several minutes to several hours, depending on the nature of the resin.
    8.2.2  Suspension Resin Slurry and Wet Resin Sample. Slurry must be 
filtered using a small Buchner funnel with vacuum to yield a wet resin 
sample. The filtering process must be continued only as long as a steady 
stream of water is exiting from the funnel. Excessive filtration time 
could result in some loss of VCM. The wet resin sample is weighed into a 
tared 20-ml vial with THF or DMAC as described earlier for resin samples 
(8.2.1) and treated the same as the resin sample. A sample of the wet 
resin is used to determine total solids as required for calculating the 
residual VCM (Section 8.3.4).
    8.2.3  Latex and Resin Solvent Solutions. Samples must be thoroughly 
mixed. Weigh 1.00 plus-minus 0.01 g of the latex or resin-
solvent solution into a 20-ml vial containing 9.00 plus-minus 
0.01 g of THF or DMAC as for the resin samples (8.2.1). Cap and shake 
until complete solution is obtained. Determine the total solids of the 
latex or resin solution sample (Section 8.3.4).
    8.2.4  Solvents and Non-viscous Liquid Samples. No preparation of 
these samples is required. The neat samples are injected directly into 
the GC.
    8.3  Analysis.
    8.3.1  Preparation of GC. Install the chromatographic column, and 
condition overnight at 70  deg.C. Do not connect the exit end of the 
column to the detector while conditioning.
    8.3.1.1  Flow Rate Adjustments. Adjust the flow rate as follows:

[[Page 252]]

    a. Nitrogen Carrier Gas. Set regulator on cylinder to read 60 psig. 
Set column flow controller on the chromatograph using the soap film 
flowmeter to yield a flow rate of 40 cc/min.
    b. Burner Air Supply. Set regulator on the cylinder at 40 psig. Set 
regulator on the chromatograph to supply air to the burner to yield a 
flow rate of 250 to 300 cc/min using the flowmeter.
    c. Hydrogen. Set regulator on cylinder to read 60 psig. Set 
regulator on the chromatograph to supply 30 to 40 cc/min using the 
flowmeter. Optimize hydrogen flow to yield the most sensitive detector 
response without extinguishing the flame. Check flow with flowmeter and 
record this flow.
    d. Nitrogen Back Flush Gas. Set regulator on the chromatograph using 
the soap film flowmeter to yield a flow rate of 40 cc/min.
    8.3.1.2  Temperature Adjustments. Set temperature as follows:
    a. Oven (chromatographic column) at 70  deg.C.
    b. Injection Port at 100  deg.C.
    c. Detector at 300  deg.C.
    8.3.1.3  Ignition of Flame Ionization Detector. Ignite the detector 
according to the manufacturer's instructions. Allow system to stabilize 
approximately 1 hour.
    8.3.1.4  Recorder. Set pen at zero and start chart drive.
    8.3.1.5  Attenuation. Set attenuation to yield desired peak height 
depending on sample VCM content.
    8.3.2  Chromatographic Analyses.
    a. Sample Injection. Remove needle from 50-microliter syringe. Open 
sample vial and draw 50-microliters of THF or DMAC sample recovery 
solution into the syringe. Recap sample vial. Attach needle to the 
syringe and while holding the syringe vertically (needle uppermost), 
eject 40 microliters into an absorbent tissue. Wipe needle with tissue. 
Now inject 10 microliters into chromatograph system. Repeat the 
injection until two consecutive values for the height of the vinyl 
chloride peak do not vary more than 5 percent. Use the average value for 
these two peak heights to compute the sample concentration.
    b. Back Flush. After 4 minutes has elapsed after sample injection, 
actuate the back flush valve to purge the first 4 feet of the 
chromatographic column of solvent and other high boilers.
    c. Sample Data. Record on the chromatograph strip chart the data 
from the sample label.
    d. Elution Time. Vinyl chloride elutes at 2.8 minutes. Acetaldehyde 
elutes at 3.7 minutes. Analysis is considered complete when chart pen 
becomes stable. After 5 minutes, reset back flush valve and inject next 
sample.
    8.3.3  Chromatograph Servicing.
    a. Septum. Replace after five sample injections.
    b. Sample Port Liner. Replace the sample port liner with a clean 
spare after five sample injections.
    c. Chromatograph Shutdown. If the chromatograph has been shut down 
overnight, rerun one or more samples from the preceding day to test 
stability and precision prior to starting on the current day's work.
    8.3.4  Determination of Total Solids (TS). For wet resin, resin 
solution, and PVC latex samples, determine the TS for each sample by 
accurately weighing approximately 3 to 5 grams of sample into a tared 
aluminum pan. The initial procedure is as follows:
    a. Where water is the major volatile component: Tare the weighing 
dish, and add 3 to 5 grams of sample to the dish. Weigh to the nearest 
milligram.
    b. Where volatile solvent is the major volatile component: Transfer 
a portion of the sample to a 20-ml screw cap vial and cap immediately. 
Weigh the vial to the nearest milligram. Uncap the vial and transfer a 
3- to 5-gram portion of the sample to a tared aluminum weighing dish. 
Recap the vial and reweigh to the nearest milligram. The vial weight 
loss is the sample weight.
    To continue, place the weighing pan in a 130  deg.C oven for 1 hour. 
Remove the dish and allow to cool to room temperature in a desiccator. 
Weigh the pan to the nearest 0.1 mg. Total solids is the weight of 
material in the aluminum pan after heating divided by the net weight of 
sample added to the pan originally times 100.

9. Calibration of the Chromatograph

    9.1  Preparation of Standards. Prepare a 1 percent by weight 
(approximate) solution of vinyl chloride in THF or DMAC by bubbling 
vinyl chloride gas from a cylinder into a tared 125-ml glass-stoppered 
flask containing THF or DMAC. The weight of vinyl chloride to be added 
should be calculated prior to this operation, i.e., 1 percent of the 
weight of THF or DMAC contained in the tared flask. This must be carried 
out in a laboratory hood. Adjust the vinyl chloride flow from the 
cylinder so that the vinyl chloride dissolves essentially completely in 
the THF or DMAC and is not blown to the atmosphere. Take particular care 
not to volatize any of the solution. Stopper the flask and swirl the 
solution to effect complete mixing. Weigh the stoppered flask to nearest 
0.1 mg to determine the exact amount of vinyl chloride added.
    Pipet 10 ml of the approximately 1 percent solution into a 100-ml 
glass-stoppered volumetric flask, and add THF or DMAC to fill to the 
mark. Cap the flask and invert 10 to 20 times. This solution contains 
approximately 1,000 ppm by weight of vinyl chloride (note the exact 
concentration).
    Pipet 50-, 10-, 5-, 1-, 0.5-, and 0.1-ml aliquots of the 
approximately 1,000 ppm solution into

[[Page 253]]

10 ml glass stoppered volumetric flasks. Dilute to the mark with THF or 
DMAC, cap the flasks and invert each 10 to 20 times. These solutions 
contain approximately 500, 100, 50, 10, 5, and 1 ppm vinyl chloride. 
Note the exact concentration of each one. These standards are to be kept 
under refrigeration in stoppered bottles, and must be renewed every 3 
months.
    9.2  Preparation of Chromatograph Calibration Curve.
    Obtain the GC for each of the six final solutions prepared in 
Section 9.1 by using the procedure in Section 8.3.2. Prepare a chart 
plotting peak height obtained from the chromatogram of each solution 
versus the known concentration. Draw a straight line through the points 
derived by the least squares method.

10. Calculations

    10.1  Response Factor. From the calibration curve described in 
Section 9.2, select the value of Cc that corresponds to 
Hc for each sample. Compute the response factor, 
Rf, for each sample as follows:

 Method 108--Determination of Particulate and Gaseous Arsenic Emissions

1. Applicability and Principle

    1.1  Applicability. This method applies to the determination of 
inorganic arsenic (As) emissions from stationary sources as specified in 
the applicable subpart.
    1.2  Principle. Particulate and gaseous arsenic emissions are 
withdrawn isokinetically from the source and collected on a glass mat 
filter and in water. The collected arsenic is then analyzed by means of 
atomic absorption spectrophotometry.

2. Apparatus

    2.1  Sampling Train. A schematic of the sampling train is shown in 
Figure 108-1; it is similar to the Method 5 train of 40 CFR part 60, 
appendix A. Note: This and all subsequent references to other methods 
refer to the methods in 40 CFR part 60, appendix A. The sampling train 
consists of the following components:
    2.1.1  Probe Nozzle, Probe Liner, Pitot Tube, Differential Pressure 
Gauge, Filter Holder, Filter Heating System, Metering System, Barometer, 
and Gas Density Determination Equipment. Same as Method 5, Sections 
2.1.1 to 2.1.6 and 2.1.8 to 2.1.10, respectively.
    2.1.2  Filter Heating System. Any heating (or cooling) system 
capable of maintaining a sample gas temperature at the exit end of the 
filter holder during sampling at 121  14  deg.C (250 
 25  deg.F). Install a temperature gauge capable of 
measuring temperature to within 3  deg.C (5.4  deg.F) at the exit end of 
the filter holder so that the sample gas temperature can be regulated 
and monitored during sampling. The tester may use systems other than the 
one shown in APTD-0591.
    2.1.3  Impingers. Four impingers connected in series with leak-free 
ground-glass fittings or any similar leak-free noncontaminating 
fittings. For the first, third, and fourth impingers, use the Greenburg-
Smith design, modified by replacing the tip with a 1.3-cm-ID (0.5 in.) 
glass tube extending to about 1.3 cm (0.5 in.) from the bottom of the 
flask. For the second impinger, use the Greenburg-Smith design with the 
standard tip. The tester may use modifications (e.g., flexible 
connections between the impingers, materials other than glass, or 
flexible vacuum lines to connect the filter holder to the condenser), 
subject to the approval of the Administrator.
    Place a thermometer, capable of measuring temperature to within 1 
deg.C (2  deg.F), at the outlet of the fourth impinger for monitoring 
purposes.

determinations, obtain an audit sample set from the Quality Assurance 
Management Office at each EPA regional office or the responsible 
enforcement office. (Note: The tester should notify the Quality 
Assurance Office or the responsible enforcement agency at least 30 days 
prior to the test date to allow sufficient time for delivery.)

4. Procedure

    4.1  Sampling. Because of the complexity of this method, testers 
must be trained and experienced with the test procedures in order to 
obtain reliable results.
    4.1.1  Pretest Preparation. Follow the general procedure given in 
Method 5, Section 4.1.1, except the filter need not be weighed.
    4.1.2  Preliminary Determinations. Follow the general procedure 
given in Method 5, Section 4.1.2, except select the nozzle size to 
maintain isokinetic sampling rates below 28 liters/min (1.0 cfm).
    4.1.3  Preparation of Collection Train. Follow the general procedure 
given in Method 5, Section 4.1.3.
    4.1.4  Leak-Check Procedures. Follow the leak-check procedures given 
in Method 5, Sections 4.1.4.1 (Pretest Leak-Check), 4.1.4.2 (Leak-Checks 
During Sample Run), and 4.1.4.3 (Post-Test Leak-Check).
    4.1.5  Arsenic Train Operation. Follow the general procedure given 
in Method 5, Section 4.1.5, except maintain a temperature of 107 deg. to 
135 deg. C (225 deg. to 275 deg. F) around the filter and maintain 
isokinetic sampling flow rates below 28 liters/min (1.0 cfm). For each 
run, record the data required on a data sheet such as the one shown in 
Figure 108-2m.
    4.1.6  Calculation of Percent Isokinetic. Same as Method 5, Section 
4.1.6.

[[Page 256]]

[GRAPHIC] [TIFF OMITTED] TC01MY92.032

    4.2  Sample Recovery. The same as Method 5, Section 4.2 except that 
0.1 N NaOH is used as the cleanup solvent instead of acetone and that 
the impinger water is treated as follows:
    Container Number 4 (Impinger Water). Clean each of the first two 
impingers and connecting glassware in the following manner:
    a. Wipe the impinger ball joints free of silicone grease, and cap 
the joints.

[[Page 257]]

    b. Weigh the impinger and liquid to within 0.5 g. Record 
in the log the weight of liquid along with a notation of any color or 
film observed in the impinger catch. The weight of liquid is needed 
along with the silica gel data to calculate the stack gas moisture 
content.
    c. Rotate and agitate each impinger, using the impinger contents as 
a rinse solution.
    d. Transfer the liquid to Container Number 4. Remove the outlet 
ball-joint cap, and drain the contents through this opening. Do not 
separate the impinger parts (inner and outer tubes) while transferring 
their contents to the cylinder.
    e. (Note: In Steps e and f below, measure and record the total 
amount of 0.1 N NaOH used for rinsing.) Pour approximately 30 ml of 0.1 
NaOH into each of the first two impingers, and agitate the impingers. 
Drain the 0.1 N NaOH through the outlet arm of each impinger into 
Container Number 4. Repeat this operation a second time; inspect the 
impingers for any abnormal conditions.
    f. Wipe the ball joints of the glassware connecting the impingers 
and the back half of the filter holder free of silicone grease, and 
rinse each piece of glassware twice with 0.1 N NaOH; transfer this rinse 
into Container Number 4. (DO NOT RINSE or brush the glass-fritted filter 
support.) Mark the height of the fluid level to determine whether 
leakage occurs during transport. Label the container to identify clearly 
its contents.
    4.2.1  Blanks. Save a portion of the 0.1 N NaOH used for cleanup as 
a blank. Take 200 ml of this solution directly from the wash bottle 
being used and place it in a plastic sample container labeled ``NaOH 
blank.'' Also save a sample of the water, and place it in a container 
labeled ``H2 O blank.''
    4.3  Arsenic Sample Preparation.
    4.3.1  Container Number 1 (Filter). Place the filter and loose 
particulate matter in a 150-ml beaker. Also, add the filtered material 
from Container Number 2 (see Section 4.3.3). Add 50 ml of 0.1 N NaOH. 
Then stir and warm on a hot plate at low heat (do not boil) for about 15 
minutes. Add 10 ml of concentrated HNO3, bring to a boil, 
then simmer for about 15 minutes. Filter the solution through a glass 
fiber filter. Wash with hot water, and catch the filtrate in a clean 
150-ml beaker. Boil the filtrate, and evaporate to dryness. Cool, add 5 
ml of 50 percent HNO3, and then warm and stir. Allow to cool. 
Transfer to a 50-ml volumetric flask, dilute to volume with water, and 
mix well.
    4.3.2  Container Number 4 (Arsenic Impinger Sample).
    Note: Prior to analysis, check the liquid level in Containers Number 
2 and Number 4; confirm as to whether leakage occurred during transport 
on the analysis sheet. If a noticeable amount of leakage occurred, 
either void the sample or take steps, subject to the approval of the 
Administrator, to adjust the final results.
    Transfer the contents of Container Number 4 to a 500-ml volumetric 
flask, and dilute to exactly 500 ml with water. Pipet 50 ml of the 
solution into a 150-ml beaker. Add 10 ml of concentrated 
HNO3, bring to a boil, and evaporate to dryness. Allow to 
cool, add 5 ml of 50 percent HNO3, and then warm and stir. 
Allow the solution to cool, transfer to a 50-ml volumetric flask, dilute 
to volume with water, and mix well.
    4.3.3  Container Number 2 (Probe Wash). See note in 4.3.2 above. 
Filter (using a glass fiber filter) the contents of Container Number 2 
into a 200-ml volumetric flask. Combine the filtered material with the 
contents of Container Number 1 (Filter).
    Dilute the filtrate to exactly 200 ml with water. Then pipet 50 ml 
into a 150-ml beaker. Add 10 ml of concentrated HNO3, bring 
to a boil, and evaporate to dryness. Allow to cool, add 5 ml of 50 
percent HNO3, and then warm and stir. Allow the solution to 
cool, transfer to a 50-ml volumetric flask, dilute to volume with water, 
and mix well.
    4.3.4  Filter Blank. Determine a filter blank using two filters from 
each lot of filters used in the sampling. Cut each filter into strips, 
and treat each filter individually as directed in Section 4.3.1, 
beginning with the sentence, ``Add 50 ml of 0.1 N NaOH.''
    4.3.5  0.1 N NaOH and Water Blanks. Treat separately 50 ml of 0.1 N 
NaOH and 50 ml water, as directed under Section 4.3.2, beginning with 
the sentence, ``Pipet 50 ml of the solution into a 150-ml beaker.''
    4.4  Spectrophotometer Preparation. Turn on the power; set the 
wavelength, slit width, and lamp current; and adjust the background 
corrector as instructed by the manufacturer's manual for the particular 
atomic absorption spectrophotometer. Adjust the burner and flame 
characteristics as necessary.
    4.5  Analysis.
    4.5.1  Arsenic Determination. Prepare standard solutions as directed 
under Section 5.1, and measure their absorbances against 0.8 N 
HNO3. Then, determine the absorbances of the filter blank and 
each sample using 0.8 N HNO3 as a reference. If the sample 
concentration falls outside the range of the calibration curve, make an 
appropriate dilution with 0.8 N HNO3 so that the final 
concentration falls within the range of the curve. Determine the arsenic 
concentration in the filter blank (i.e., the average of the two blank 
values from each lot). Next, using the appropriate standard curve, 
determine the arsenic concentration in each sample fraction.
    4.5.1.1  Arsenic Determination at Low Concentration. The lower limit 
of flame atomic absorption spectrophotometry is 10  g As/ml. If 
the arsenic concentration of any sample is at a lower level, use the 
graphite furnace or vapor generator which is available as an accessory 
component. The analyst also

[[Page 258]]

has the option of using either of these accessories for samples whose 
concentrations are between 10 and 30  g/ml. Follow the 
manufacturer's instructions in the use of such equipment.
    4.5.1.1.1  Vapor Generator Procedure. Place a sample containing 
between 0 and 5  g of arsenic in the reaction tube, and dilute 
to 15 ml with water. Since there is some trial and error involved in 
this procedure, it may be necessary to screen the samples by 
conventional atomic absorption until an approximate concentration is 
determined. After determining the approximate concentration, adjust the 
volume of the sample accordingly. Pipet 15 ml of concentrated HCl into 
each tube. Add 1 ml of 30 percent KI solution. Place the reaction tube 
into a 50 deg. C water bath for 5 minutes. Cool to room temperature. 
Connect the reaction tube to the vapor generator assembly. When the 
instrument response has returned to baseline, inject 5.0 ml of 5 percent 
NaBH4, and integrate the resulting spectrophotometer signal 
over a 30-second time period.
    4.5.1.1.2  Graphite Furnace Procedure. Dilute the digested sample so 
that a 5-ml aliquot contains less than 1.5  g of arsenic. Pipet 
5 ml of this digested solution into a 10-ml volumetric flask. Add 1 ml 
of the 1 percent nickel nitrate solution, 0.5 ml of 50 percent 
HNO3, and 1 ml of the 3 percent hydrogen peroxide and dilute 
to 10 ml with water. The sample is now ready to inject in the furnace 
for analysis.
    Because instruments from different manufacturers are different, no 
detailed operating instructions will be given here. Instead, the analyst 
should follow the instructions provided with his particular instrument.
    4.5.1.2  Check for Matrix Effects on the Arsenic Results. Same as 
Method 12, Section 5.4.2.
    4.5.2  Container Number 3 (Silica Gel). The tester may conduct this 
step in the field. Weigh the spent silica gel (or silica gel plus 
impinger) to the nearest 0.5 g; record this weight.
    4.6  Audit Analysis. Concurrently, analyze the two unknown audit 
samples with each set of compliance samples to evaluate the techniques 
of the analyst and the standards preparation. (Note: It is recommended 
that known quality control samples be analyzed prior to the compliance 
and audit sample analysis to optimize the system's accuracy and 
precision. One source of these samples is the Source Branch listed in 
Section 3.3.16.) The same analyst, analytical reagents, and analytical 
system shall be used both for each set or sets of compliance samples and 
the EPA audit samples; if this condition is met, audit samples need not 
be included with any additional compliance analyses performed within the 
succeeding 30-day period for the same enforcement agency. An audit 
sample set may not be used to validate different sets of compliance 
samples under the jurisdiction of different enforcement agencies unless 
prior arrangements are made with both enforcement agencies.
    Calculate the concentration in g/m \3\ using the specified sample 
volume in the audit instructions. (Note: The analyst may determine 
immediately whether the audit analyses acceptable by reporting the audit 
results in g/m \3\ and compliance results in g/ml by 
telephone). Include the results of both audit samples, their 
identification numbers, and the analysts' names with the results of the 
compliance determination samples in appropriate reports to the EPA 
regional office or the appropriate enforcement agency. Include this 
information with subsequent compliance analyses for the same enforcement 
agency during the succeeding 30-day period.

5. Calibration

    Maintain a laboratory log of all calibrations.
    5.1  Standard Solutions. For the high level procedure pipet 1, 3, 5, 
8, and 10 ml of the 1.0-mg As/ml stock solution into separate 100-ml 
volumetic flasks, each containing 5 ml of concentrated HNO 3. 
If the low level vapor generator procedure is used, pipet 1, 2, 3, and 5 
ml of 1.0 g As/ml standard solution into the separate reaction 
tubes. For the low level graphite furnace procedure, pipet 1, 5, 10 and 
15 ml of 1.0 g As/ml standard solution into the separate flasks 
along with 2 ml of the 5 percent nickel nitrate solution and 10 ml of 
the 3 percent hydrogen peroxide solution. Dilute to the mark with water. 
Then treat the standards in the same manner as the samples (Section 
4.5.1).
    Check these absorbances frequently against 0.8 N HNO 3 
(reagent blank) during the analysis to insure that base-line drift has 
not occurred. Prepare a standard curve of absorbance versus 
concentration. (Note: For instruments equipped with direct concentration 
readout devices, preparation of a standard curve will not be necessary.) 
In all cases, follow calibration and operational procedures in the 
manufacturers' instruction manual.
    5.2 Sampling Train Calibration. Calibrate the sampling train 
components according to the indicated Sections of Method 5: Probe Nozzle 
(Section 5.1), Pitot Tube Assembly (Section 5.2), Metering System 
(Section 5.3), Probe Heater (Section 5.4), Temperature Gauges (Section 
5.5), Leak Check of Metering System (Section 5.6), and Barometer 
(Section 5.7).

two vials of unknown concentrations. Only when making compliance 
determinations, obtain an audit sample set from the Quality Assurance 
Management Office at each EPA regional office or the responsible 
enforcement office. (NOTE: The tester should notify the Quality 
Assurance Office or the responsible enforcement agency at least 30 days 
prior to the test date to allow sufficient time for delivery.)

4. Procedure

    4.1  Sample Collection. A sample that is representative of the ore 
lot to be tested must be taken prior to analysis. The sample must be 
ground into a finely pulverized state. (A portion of the samples 
routinely collected for metals analysis may be used provided the sample 
is representative of the ore being tested.)
    4.2  Sample Preparation. Weigh 50 to 500 mg of finely pulverized 
sample to the nearest 0.1 mg. Transfer the sample into the Teflon cup of 
the digestion bomb, and add 2 ml each of concentrated HNO3 
and HF. Seal the bomb immediately to prevent the loss of any volatile 
arsenic compounds that may form. Heat in an oven 105  deg.C for 2 hours. 
Then remove the bomb from the oven and allow it to cool. Using a Teflon 
filter, quantitatively filter the digested sample into a 50-ml 
polypropylene volumetric flask. Rinse the bomb three times with small 
portions of 0.5 N HNO3, and filter the rinses into the flask. 
Add 5 ml of KCl solution to the flask, and dilute to 50 ml with 0.5 N 
HNO3.
    4.3  Spectrophotometer Preparation. Turn on the power; set the 
wavelength, slit width, and lamp current; and adjust the background 
corrector as instructed by the manufacturer's manual for the particular 
atomic absorption spectrophotometer. Adjust the burner and flame 
characteristics as necessary.
    4.4  Preparation of Standard Solutions. Pipet 1, 5, 10, and 25 ml of 
the stock As solution into separate 100-ml volumetric flasks. Add 10 ml 
KCl solution and dilute to the mark with 0.5 N HNO3. This 
will give standard concentrations of 10, 50, 100, and 250 g As/
ml. For low-level-arsenic samples that require the use of a graphite 
furnace or vapor generator, follow the procedures in Section 4.4.1.

[[Page 261]]

    Dilute 10 ml of KCl solution to 100 ml with 0.5 N HNO3 
and use as a reagent blank. Measure the standard absorbances against the 
reagent blank. Check these absorbances frequently against the blank 
during the analysis to assure that baseline drift has not occurred.
    Prepare a standard curve of absorbance versus concentration. (Note: 
For instruments equipped with direct concentration readout devices, 
preparation of a standard curve will not be necessary.) In all cases 
follow calibration and operational procedures in the manufacturer's 
instruction manual. Maintain a laboratory log of all calibrations.
    4.4.1  Arsenic Determination at Low Concentration. The lower limit 
of flame atomic absorption spectrophotometry is 10 g As/ml. If 
the arsenic concentration of any sample is at a lower level, use the 
vapor generator or graphite furnace which is available as an accessory 
component. Follow the manufacturer's instructions in the use of such 
equipment.
    4.4.1.1  Vapor Generator Procedure. Place a sample containing 
between 0 and 5 g of arsenic in the reaction tube, and dilute 
to 15 ml with water. Since there is some trial and error involved in 
this procedure, it may be necessary to screen the samples by 
conventional atomic absorption until an approximate concentration is 
determined. After determining the approximate concentration, adjust the 
volume of the sample accordingly. Pipet 15 ml of concentrated HCl into 
each tube. Add 1 ml of 30 percent KI solution. Place the reaction tube 
into a 50  deg.C water bath for 5 minutes. Cool to room temperature. 
Connect the reaction tube to the vapor generator assembly. When the 
instrument response has returned to baseline, inject 5.0 ml of 5 percent 
NaBH4 and integrate the resulting spectrophotometer signal 
over a 30-second time period.
    4.4.1.2  Graphite Furnace Procedure. Pipet 5 ml of this digested 
solution into a 10-ml volumetric flask. Add 1 ml of the 1 percent nickel 
nitrate solution, 0.5 ml of 50 percent HNO3, and 1 ml of the 
3 percent hydrogen peroxide and dilute to 10 ml with water. The sample 
is now ready to inject in the furnace for analysis.
    Because instruments from different manufacturers are different, no 
detailed operating instructions are given here. Instead, the analyst 
should follow the instructions provided with the particular instrument.
    4.5  Analysis.
    4.5.1  Arsenic Determination. Determine the absorbance of each 
sample using the blank as a reference. If the sample concentration falls 
outside the range of the calibration curve, make an appropriate dilution 
with 0.5 N HNO3 so that the final concentration falls within 
the range of the curve. From the curve, determine the As concentration 
in each sample.
    4.5.2  Mandatory Check for Matrix Effects on the Arsenic Results. 
Same as in Method 12, Section 5.4.2.
    4.5.3  Audit analysis. With each set or sets of source compliance 
samples, analyze the two unknown audit samples in the same manner as the 
source samples to evaluate the techniques of the analyst and the 
standards preparation. The same analyst, analytical reagents, and 
analytical system shall be used both for each set or sets of compliance 
samples and the EPA audit samples; if this condition is met, it is not 
necessary to analyze additional audit samples for subsequent compliance 
analyses performed for the same enforcement agency within a 30-day 
period. An audit sample set may not be used to validate different sets 
of compliance samples under the jurisdiction of different enforcement 
agencies unless prior arrangements are made with both enforcement 
agencies.
    Calculate the concentration in g/m\3\ using the specified sample 
volume in the audit instructions. (Note: The acceptability of the 
analyses of the audit samples may be obtained immediately by reporting 
the audit and compliance results by telephone). Include the results of 
both audit samples, their identification numbers, and the analysts' 
names with the results of the compliance determination samples in 
appropriate reports to the EPA regional office or the appropriate 
enforcement agency. Include this information with subsequent compliance 
analyses for the same enforcement agency during the succeeding 30-day 
period.

4. Procedure

    4.1  Sample Preparation and Distillation.
    4.1.1  Weigh 1.0 g of finely pulverized sample to the nearest 0.1 
mg. Transfer the sample to a 300-ml Erlenmeyer flask and add 15 ml of 
HNO3, 4 ml HCl, 2 ml HF, 3 ml HClO4, and 15 ml 
H2 SO4. In a HClO4 fume hood, heat on a 
hot plate to decompose the sample. Then heat while swirling over an open 
flame until dense, white fumes evolve. Cool, add 15 ml of water, swirl 
to hydrate the H2SO4 completely, and add several 
boiling granules. Cool to room temperature.
    4.1.2  Add 1 g of KBr, 1 g hydrazine sulfate, and 50 ml HCl. 
Immediately attach the distillation head with thermometer and dip the 
side arm into a 50-ml graduated cylinder containing 25 ml of water and 2 
ml of bromine water. Keep the graduated cylinder immersed in a beaker of 
cold water during distillation. Distill until the temperature of the 
vapor in the flask reaches 107  deg.C. When distillation is complete, 
remove the flask from the hot plate, and simultaneously wash down the 
side arm with water as it is removed from the cylinder.
    4.1.3  If the expected arsenic content is in the range of 0.0020 to 
0.10 percent, dilute the distillate to the 50-ml mark of the cylinder 
with water, stopper, and mix. Transfer a 5.0-ml aliquot to a 50-ml 
volumetric flask. Add 10 ml of water and a boiling granule. Place the 
flask on a hot plate, and heat gently until the bromine is expelled and 
the color of methyl orange indicator persists upon the addition of 1-2 
drops. Cool the flask to room temperature. Neutralize just to the yellow 
color of the indicator with dropwise additions of NH4OH. 
Bring back to the red color by dropwise addition of dilute HCl, and add 
10 ml excess. Proceed with the molybdenum blue color development as 
described in section 4.2.
    4.1.4  If the expected arsenic content is in the range of 0.0002 to 
0.0010 percent As, transfer either the entire initial distillate or the 
measured remaining distillate from above to a 250-ml beaker. Wash the 
cylinder with two successive portions of concentrated HNO3, 
adding each portion to the distillate in the beaker. Add 4 ml of 
concentrated HClO4, a boiling granule, and cover with a flat 
watch glass placed slightly to one side. Boil gently on a hot plate 
until the volume is reduced to approximately 10 ml. Add 3 ml of 
HNO3, and continue the evaporation until HClO4 is 
refluxing on the beaker cover. Cool briefly, rinse the underside of the 
watch glass and the inside of the beaker with about 3-5 ml of water, 
cover, and continue the evaporation to expel all but 2 ml of the 
HClO4. NOTE: If the solution appears cloudy due to a small 
amount of antimony distilling over, add 4 ml of 1/1 HCl/water and 5 ml 
of water, cover, and warm gently until clear. If cloudiness persists, 
add 5 ml of HNO3 and 2 ml H2SO4. 
Continue the evaporation of the volatile acids to solubilize the 
antimony until dense white fumes of H2SO4 appear. 
Retain at least 1 ml of the H2SO4. To the 2 ml of 
HClO4 solution or 1 ml of the H2 SO4 
solution, add 15 ml of water, boil gently for 2 minutes, and then cool. 
Proceed with the molybdenum blue color development by neutralizing the 
solution directly in the beaker just to the yellow indicator color by 
dropwise addition of NH4OH. Just bring back the red color by 
dropwise addition of dilute HCl. Transfer the solution to a 50-ml 
volumetric flask, and rinse the beaker successively with 10 ml of dilute 
HCl, followed by several small portions of water. At this point the 
volume of solution in the flask should be no more than 40 ml. Continue 
with the color development as described in section 4.2.
    4.2  Analysis.
    4.2.1  Add 1 ml of KBrO3 solution to the flask and heat 
on a low-temperature hot plate to about 50  deg.C to oxidize the arsenic 
and methyl orange. Add 5.0 ml of ammonium molybdate solution to the warm 
solution and mix. Add 2.0 ml of hydrazine sulfate solution, dilute until 
the solution comes within the neck of the flask, and mix. Place in a 
400-ml beaker, 80 percent full of boiling water, for 10 minutes. Enough 
heat must be supplied to prevent the water bath from cooling much below 
the boiling point upon inserting the volumetric flask. Remove the flask, 
cool to room temperature, dilute to the mark, and mix.
    4.2.2  Transfer a suitable portion of the reference solution to an 
absorption cell, and adjust the photometer to the initial setting, using 
a light band centered at 660 nm. While

[[Page 266]]

maintaining this photometer adjustment, take the photometric readings of 
the calibration solutions followed by the samples.
    4.3  Preparation of the Calibration Curve. Transfer 1.0, 2.0, 4.0, 
8.0, 12.0, 16.0, and 20.0 ml of standard arsenic solution (10  
g/ml) to each of the seven 50-ml volumetric flasks. Dilute to 20 ml with 
dilute HCl. Add one drop of methyl orange solution and neutralize to the 
yellow color with dropwise addition of NH4OH. Just bring back 
to the red color by dropwise addition of dilute HCl, and add 10 ml in 
excess. Proceed with the color development as described in section 4.2. 
Plot the photometric readings of the calibration solutions against 
g As per 50 ml of solution. From the curve, determine the As 
concentration in each sample.

  Method 111--Determination of Polonium-210 Emissions From Stationary 
                                 Sources

    Performance of this method should not be attempted by persons 
unfamiliar with the use of equipment for measuring radioactive 
disintegration rates.

1.0  Applicability and Principle

    1.1  Applicability. This method is applicable to the determination 
of polonium-210 emissions in particulate samples collected in stack 
gases. Samples should be analyzed within 30 days of collection to 
minimize error due to growth of polonium-210 from any lead-210 present 
in the sample.
    1.2  Principle A particulate sample is collected from stack gases as 
described in Method 5 of appendix A to 40 CFR part 60. The polonium-210 
in the sample is put in solution, deposited on a metal disc, and the 
radioactive disintegration rate measured. Polonium in acid solution 
spontaneously deposits on surfaces of metals that are more 
electropositive than polonium. This principle is routinely used in the 
radiochemical analysis of polonium-210.

4.0  Procedure

    4.1  Sample Preparation.
    The glass fiber filter and acetone rinse from Method 5 of appendix A 
to 40 CFR part 60 are combined and dissolved as described below.
    4.1.1  Add polonium-209 tracer to the acetone rinse in the glass 
beaker from Method 5 in an amount approximately equal to the amount of 
polonium-210 expected in the total particulate sample. Add 16 M nitric 
acid to the beaker to digest and loosen the residue.
    4.1.2  Transfer the residue from the glass beaker to a teflon beaker 
containing the glass fiber filter. Rinse the glass beaker with 16 M 
nitric acid. If necessary reduce the volume in the beaker by evaporation 
until all of the nitric acid from the glass beaker has been transferred 
to the teflon beaker.
    4.1.3  Add 30 ml of 29 M hydrofluoric acid to the teflon beaker and 
evaporate to near dryness on a hot plate in a properly operating hood. 
Caution: Do not allow the residue to go to dryness and overheat; this 
will result in loss of polonium.
    4.1.4  Repeat step 4.1.3 until filter is dissolved.
    4.1.5  Add 100 ml of 16 M nitric acid to the residue in the teflon 
beaker and evaporate to near dryness. Caution: Do not allow the residue 
to go to dryness.
    4.1.6  Add 50 ml of 16 M nitric acid and 10 ml of 12 M perchloric 
acid to the teflon beaker and heat until dense fumes of perchloric acid 
are evolved.
    4.1.7  Repeat steps 4.1.3 to 4.1.6 as necessary until sample is 
completely dissolved.
    4.1.8  Add 10 ml of 12 M hydrochloric acid and evaporate to dryness. 
Repeat additions and evaporations several times.
    4.1.9  Transfer the sample to a 250 ml volumetric flask and dilute 
to volume with 3 M hydrochloric acid.

    4.2  Sample Screening.
    The samples are checked for radioactivity levels to avoid 
contaminaton of the alpha spectrometry system. Use the following 
screening method:
    4.2.1  Twenty ml of 1 M HCl are added to a 150 ml beaker.
    4.2.2  One ml of the lanthanum carrier solution, 0.1 mg lanthanum 
per ml, is added to beaker.

    4.2.5  The solution from Section 4.2.4 is allowed to stand for a 
minimum of 30 minutes.
    4.2.6  The solution is filtered through a filter membrane using 
suction.
    4.2.7  The membrane is washed with 10 ml of distilled water and 5 ml 
of ethanol.
    4.2.8  The membrane is allowed to air dry and then mounted, 
filtration side up, on a planchet lined with double-side plastic tape.
    4.2.9  The membrane is radioassayed using an internal proportional 
alpha counter.
    4.2.10  The activity of the original solution from Section 4.1.7 is

solution is in the constant temperature bath for plating.
    4.4.5  Suspend a silver disc in the heated solution using a glass or 
plastic rod with a hook inserted through the hole in the disc. The disc 
should be totally immersed in the solution at all times.

    Background counts used in all equations are determined by performing 
the specific analysis required using the analytical reagents only. This 
should be repeated every 10 analyses.
    4.7  Determination of Instrument Background.
    Instrument backgrounds of the internal proportional counter and 
alpha spectrometry system should be determined on a weekly basis. 
Instrument background should not exceed procedure background. If this 
occurs, it may be due to a malfunction or contamination.

    Many different types of facilities release radionuclides into air. 
These radionuclides differ in the chemical and physical forms, half-
lives and type of radiation emitted. The appropriate combination of 
sample extraction, collection and analysis for an individual 
radionuclide is dependent upon many interrelated factors including the 
mixture of other radionuclides present. Because of this wide range of 
conditions, no single method for monitoring or sample collection and 
analysis of a radionuclide is applicable to all types of facilities. 
Therefore, a series of methods based on ``principles of measurement'' 
are described for monitoring and sample collection and analysis which 
are applicable to the measurement of radionuclides found in effluent 
streams at stationary sources. This approach provides the user with the 
flexibility to choose the most appropriate combination of monitoring and 
sample collection and analysis methods which are applicable to the 
effluent stream to be measured.

2. Stack Monitoring and Sample Collection Methods


[[Page 271]]


    Monitoring and sample collection methods are described based on 
``principles of monitoring and sample collection'' which are applicable 
to the measurement of radionuclides from effluent streams at stationary 
sources. Radionuclides of most elements will be in the particulate form 
in these effluent streams and can be readily collected using a suitable 
filter media. Radionuclides of hydrogen, oxygen, carbon, nitrogen, the 
noble gases and in some circumstances iodine will be in the gaseous 
form. Radionuclides of these elements will require either the use of an 
in-line or off-line monitor to directly measure the radionuclides, or 
suitable sorbers, condensers or bubblers to collect the radionuclides.
    2.1  Radionuclides as Particulates. The extracted effluent stream is 
passed through a filter media to remove the particulates. The filter 
must have a high efficiency for removal of sub-micron particles. The 
guidance in ANSI N13.1--1969 shall be followed in using filter media to 
collect particulates (incorporated by reference-see Sec. 61.18).
    2.2  Radionuclides as Gases.
    2.2.1  The Radionuclide Tritium (H-3). Tritium in the form of water 
vapor is collected from the extracted effluent sample by sorption, 
condensation or dissolution techniques. Appropriate collectors may 
include silica gel, molecular sieves, and ethylene glycol or water 
bubblers.
    Tritium in the gaseous form may be measured directly in the sample 
stream using Method B-1, collected as a gas sample or may be oxidized 
using a metal catalyst to tritiated water and collected as described 
above.
    2.2.2  Radionuclides of Iodine. Iodine is collected from an 
extracted sample by sorption or dissolution techniques. Appropriate 
collectors may include charcoal, impregnated charcoal, metal zeolite and 
caustic solutions.
    2.2.3  Radionuclides of Argon, Krypton and Xenon. Radionuclides of 
these elements are either measured directly by an in-line or off-line 
monitor, or are collected from the extracted sample by low temperature 
sorption techniques, Appropriate sorbers may include charcoal or metal 
zeolite.
    2.2.4  Radionuclides of Oxygen, Carbon, Nitrogen and Radon. 
Radionuclides of these elements are measured directly using an in-line 
or off-line monitor. Radionuclides of carbon in the form of carbon 
dioxide may be collected by dissolution in caustic solutions.
    2.3  Definition of Terms
    In-line monitor means a continuous measurement system in which the 
detector is placed directly in or adjacent to the effluent stream. This 
may involve either gross radioactivity measurements or specific 
radionuclide measurements. Gross measurements shall be made in 
conformance with the conditions specified in Methods A-4, B-2 and G-4.
    Off-line monitor means a measurement system in which the detector is 
used to continuously measure an extracted sample of the effluent stream. 
This may involve either gross radioactivity measurements or specific 
radionuclide measurements. Gross measurements shall be made in 
conformance with the conditions specified in Methods A-4, B-2 and G-4.
    Sample collection means a procedure in which the radionuclides are 
removed from an extracted sample of the effluent using a collection 
media. These collection media include filters, absorbers, bubblers and 
condensers. The collected sample is analyzed using the methods described 
in Section 3.

3. Radionuclide Analysis Methods

    A series of methods based on ``principles of measurement'' are 
described which are applicable to the analysis of radionuclides 
collected from airborne effluent streams at stationary sources. These 
methods are applicable only under the conditions stated and within the 
limitations described. Some methods specify that only a single 
radionuclide be present in the sample or the chemically separated 
sample. This condition should be interpreted to mean that no other 
radionuclides are present in quantities which would interfere with the 
measurement.
    Also identified (Table 1) are methods for a selected list of 
radionuclides. The listed radionuclides are those which are most 
commonly used and which have the greatest potential for causing dose to 
members of the public. Use of methods based on principles of measurement 
other than those described in this section must be approved in advance 
of use by the Administrator. For radionuclides not listed in Table 1, 
any of the described methods may be used provided the user can 
demonstrate that the applicability conditions of the method have been 
met.
    The type of method applicable to the analysis of a radionuclide is 
dependent upon the type of radiation emitted, i.e., alpha, beta or 
gamma. Therefore, the methods described below are grouped according to 
principles of measurements for the analysis of alpha, beta and gamma 
emitting radionuclides.
    3.1  Methods for Alpha Emitting Radionuclides
    3.1.1  Method A-1, Radiochemistry-Alpha Spectrometry.
    Principle: The element of interest is separated from other elements, 
and from the sample matrix using radiochemical techniques. The procedure 
may involve precipitation, ion exchange, or solvent extraction. Carriers 
(elements chemically similar to the element of interest) may be used. 
The element is deposited on a planchet in a very

[[Page 272]]

thin film by electrodeposition or by coprecipitation on a very small 
amount of carrier, such as lanthanum fluoride. The deposited element is 
then counted with an alpha spectrometer. The activity of the nuclide of 
interest is measured by the number of alpha counts in the appropriate 
energy region. A correction for chemical yield and counting efficiency 
is made using a standardized radioactive nuclide (tracer) of the same 
element. If a radioactive tracer is not available for the element of 
interest, a predetermined chemical yield factor may be used.
    Applicability: This method is applicable for determining the 
activity of any alpha-emitting radionuclide, regardless of what other 
radionuclides are present in the sample provided the chemical separation 
step produces a very thin sample and removes all other radionuclides 
which could interfere in the spectral region of interest. APHA-605(2), 
ASTM-D-3972(13).
    3.1.2  Method A-2, Radiochemistry-Alpha Counting.
    Principle: The element of interest is separated from other elements, 
and from the sample matrix using radiochemistry. The procedure may 
involve precipitation, ion exchange, or solvent extraction. Carriers 
(elements chemically similar to the element of interest) may be used. 
The element is deposited on a planchet in a thin film and counted with a 
alpha counter. A correction for chemical yield (if necessary) is made. 
The alpha count rate measures the total activity of all emitting 
radionuclides of the separated element.
    Applicability: This method is applicable for the measurement of any 
alpha-emitting radionuclide, provided no other alpha emitting 
radionuclide is present in the separated sample. It may also be 
applicable for determining compliance, when other radionuclides of the 
separated element are present, provided that the calculated emission 
rate is assigned to the radionuclide which could be present in the 
sample that has the highest dose conversion factor. IDO-12096(18).
    3.1.3  Method A-3, Direct Alpha Spectrometry.
    Principle: The sample, collected on a suitable filter, is counted 
directly on an alpha spectrometer. The sample must be thin enough and 
collected on the surface of the filter so that any absorption of alpha 
particle energy in the sample or the filter, which would degrade the 
spectrum, is minimal.
    Applicability: This method is applicable to simple mixtures of alpha 
emitting radionuclides and only when the amount of particulates 
collected on the filter paper are relatively small and the alpha spectra 
is adequately resolved. Resolutions should be 50 keV (FWHM) or better, 
ASTM-D-3084(16).
    3.1.4  Method A-4, Direct Alpha Counting (Gross alpha 
determination).
    Principle: The sample, collected on a suitable filter, is counted 
with an alpha counter. The sample must be thin enough so that self-
absorption is not significant and the filter must be of such a nature 
that the particles are retained on the surface.
    Applicability: Gross alpha determinations may be used to measure 
emissions of specific radionuclides only (1) when it is known that the 
sample contains only a single radionuclide, or the identity and isotopic 
ratio of the radionuclides in the sample are well-known, and (2) 
measurements using either Method A-1, A-2 or A-5 have shown that this 
method provides a reasonably accurate measurement of the emission rate. 
Gross alpha measurements are applicable to unidentified mixtures of 
radionuclides only for the purposes and under the conditions described 
in section 3.7. APHA-601(3), ASTM-D-1943(10).
    3.1.5  Method A-5, Chemical Determination of Uranium.
    Principle: Uranium may be measured chemically by either colorimetry 
or fluorometry. In both procedures, the sample is dissolved, the uranium 
is oxidized to the hexavalent form and extracted into a suitable 
solvent. Impurities are removed from the solvent layer. For colorimetry, 
dibenzoylmethane is added, and the uranium is measured by the absorbance 
in a colorimeter. For fluorometry, a portion of the solution is fused 
with a sodium fluoride-lithium fluoride flux and the uranium is 
determined by the ultraviolet activated fluorescence of the fused disk 
in a fluorometer.
    Applicability: This method is applicable to the measurements of 
emission rates of uranium when the isotopic ratio of the uranium 
radionuclides is well known. ASTM-E-318(15), ASTM-D-2907(14).
    3.1.6  Method A-6, Radon-222--Continuous Gas Monitor.
    Principle: Radon-222 is measured directly in a continuously 
extracted sample stream by passing the air stream through a calibrated 
scintillation cell. Prior to the scintillation cell, the air stream is 
treated to remove particulates and excess moisture. The alpha particles 
from radon-222 and its decay products strike a zinc sulfide coating on 
the inside of the scintillation cell producing light pulses. The light 
pulses are detected by a photomultiplier tube which generates electrical 
pulses. These pulses are processed by the system electronics and the 
read out is in pCi/l of radon-222.
    Applicability: This method is applicable to the measurement of 
radon-222 in effluent streams which do not contain significant 
quantities of radon-220. Users of this method should calibrate the 
monitor in a radon calibration chamber at least twice per year. The 
background of the monitor should also be

[[Page 273]]

checked periodically by operating the instrument in a low radon 
environment. EPA 520/1-89-009(24).
    3.1.7  Method A-7, Radon-222-Alpha Track Detectors
    Principle: Radon-222 is measured directly in the effluent stream 
using alpha track detectors (ATD). The alpha particles emitted by radon-
222 and its decay products strike a small plastic strip and produce 
submicron damage tracks. The plastic strip is placed in a caustic 
solution that accentuates the damage tracks which are counted using a 
microscope or automatic counting system. The number of tracks per unit 
area is correlated to the radon concentration in air using a conversion 
factor derived from data generated in a radon calibration facility.
    Applicability: Prior approval from EPA is required for use of this 
method. This method is only applicable to effluent streams which do not 
contain significant quantities of radon-220, unless special detectors 
are used to discriminate against radon-220. This method may be used only 
when ATDs have been demonstrated to produce data comparable to data 
obtained with Method A-6. Such data should be submitted to EPA when 
requesting approval for the use of this method. EPA 520/1-89-009(24).
    3.2  Methods for Gaseous Beta Emitting Radionuclides.
    3.2.1  Method B-1, Direct Counting in Flow-Through Ionization 
Chambers.
    Principle: An ionization chamber containing a specific volume of gas 
which flows at a given flow rate through the chamber is used. The sample 
(effluent stream sample) acts as the counting gas for the chamber. The 
activity of the radionuclide is determined from the current measured in 
the ionization chamber.
    Applicability: This method is applicable for measuring the activity 
of a gaseous beta-emitting radionuclide in an effluent stream that is 
suitable as a counting gas, when no other beta-emitting nuclides are 
present. DOE/EP-0096(17), NCRP-58(23).
    3.2.2  Method B-2, Direct Counting With In-line or Off-line Beta 
Detectors.
    Principle: The beta detector is placed directly in the effluent 
stream (in-line) or an extracted sample of the effluent stream is passed 
through a chamber containing a beta detector (off-line). The activities 
of the radionuclides present in the effluent stream are determined from 
the beta count rate, and a knowledge of the radionuclides present and 
the relationship of the gross beta count rate and the specific 
radionuclide concentration.
    Applicability: This method is applicable only to radionuclides with 
maximum beta particle energies greater then 0.2 MeV. This method may be 
used to measure emissions of specific radionuclides only when it is 
known that the sample contains only a single radionuclide or the 
identity and isotopic ratio of the radionuclides in the effluent stream 
are well known. Specific radionuclide analysis of periodic grab samples 
may be used to identify the types and quantities of radionuclides 
present and to establish the relationship between specific radionuclide 
analyses and gross beta count rates.
    This method is applicable to unidentified mixtures of gaseous 
radionuclides only for the purposes and under the conditions described 
in section 3.7.
    3.3  Methods for Non-Gaseous Beta Emitting Radionuclides.
    3.3.1  Method B-3, Radiochemistry-Beta Counting.
    Principle: The element of interest is separated from other elements, 
and from the sample matrix by radiochemistry. This may involve 
precipitation, distillation, ion exchange, or solvent extraction. 
Carriers (elements chemically similar to the element of interest) may be 
used. The element is deposited on a planchet, and counted with a beta 
counter. Corrections for chemical yield, and decay (if necessary) are 
made. The beta count rate determines the total activity of all 
radionuclides of the separated element. This method may also involve the 
radiochemical separation and counting of a daughter element, after a 
suitable period of ingrowth, in which case it is specific for the parent 
nuclide.
    Applicability: This method is applicable for measuring the activity 
of any beta-emitting radionuclide, with a maximum energy greater than 
0.2 MeV, provided no other radionuclide is present in the separated 
sample. APHA-608(5).
    3.3.2  Method B-4, Direct Beta Counting (Gross beta determination).
    Principle: The sample, collected on a suitable filter, is counted 
with a beta counter. The sample must be thin enough so that self-
absorption corrections can be made.
    Applicability: Gross beta measurements are applicable only to 
radionuclides with maximum beta particle energies greater than 0.2 MeV. 
Gross beta measurements may be used to measure emissions of specific 
radionuclides only (1) when it is known that the sample contains only a 
single radionuclide, and (2) measurements made using Method B-3 show 
reasonable agreement with the gross beta measurement. Gross beta 
measurements are applicable to mixtures of radionuclides only for the 
purposes and under the conditions described in section 3.7. APHA-602(4), 
ASTM-D-1890(11).
    3.3.3  Method B-5, Liquid Scintillation Spectrometry.
    Principle: An aliquot of a collected sample or the result of some 
other chemical separation or processing technique is added to a liquid 
scintillation ``cocktail'' which is viewed by photomultiplier tubes in a 
liquid scintillation spectrometer. The spectrometer

[[Page 274]]

is adjusted to establish a channel or ``window'' for the pulse energy 
appropriate to the nuclide of interest. The activity of the nuclide of 
interest is measured by the counting rate in the appropriate energy 
channel. Corrections are made for chemical yield where separations are 
made.
    Applicability: This method is applicable to any beta-emitting 
nuclide when no other radionuclide is present in the sample or the 
separated sample provided that it can be incorporated in the 
scintillation cocktail. This method is also applicable for samples which 
contain more than one radionuclide but only when the energies of the 
beta particles are sufficiently separated so that they can be resolved 
by the spectrometer. This method is most applicable to the measurement 
of low-energy beta emitters such as tritium and carbon-14. APHA-609(6), 
EML-LV-539-17(19).
    3.4  Gamma Emitting Radionuclides
    3.4.1  Method G-1, High Resolution Gamma Spectrometry.
    Principle: The sample is counted with a high resolution gamma 
detector, usually either a Ge(Li) or a high purity Ge detector, 
connected to a multichannel analyzer or computer. The gamma emitting 
radionuclides in the sample are measured from the gamma count rates in 
the energy regions characteristic of the individual radionuclide. 
Corrections are made for counts contributed by other radionuclides to 
the spectral regions of the radionuclides of interest. Radiochemical 
separations may be made prior to counting but are usually not necessary.
    Applicability: This method is applicable to the measurement of any 
gamma emitting radionuclide with gamma energies greater than 20 keV. It 
can be applied to complex mixtures of radionuclides. The samples counted 
may be in the form of particulate filters, absorbers, liquids or gases. 
The method may also be applied to the analysis of gaseous gamma emitting 
radionuclides directly in an effluent stream by passing the stream 
through a chamber or cell containing the detector. ASTM-3649(9), IDO-
12096(18).
    3.4.2  Method G-2, Low Resolution Gamma Spectrometry.
    Principle: The sample is counted with a low resolution gamma 
detector, a thallium activated sodium iodide crystal. The detector is 
coupled to a photomultiplier tube and connected to a multichannel 
analyzer. The gamma emitting radionuclides in the sample are measured 
from the gamma count rates in the energy regions characteristic of the 
individual radionuclides. Corrections are made for counts contributed by 
other radionuclides to the spectral regions of the radionuclides of 
interest. Radiochemical separation may be used prior to counting to 
obtain less complex gamma spectra if needed.
    Applicability: This method is applicable to the measurement of gamma 
emitting radionuclides with energies greater than 100 keV. It can be 
applied only to relatively simple mixtures of gamma emitting 
radionuclides. The samples counted may be in the form of particulate 
filters, absorbers, liquids or gas. The method can be applied to the 
analysis of gaseous radionuclides directly in an effluent stream by 
passing the gas stream through a chamber or cell containing the 
detector. ASTM-D-2459(12), EMSL-LV-0539-17(19).
    3.4.3  Method G-3, Single Channel Gamma Spectrometry.
    Principle: The sample is counted with a thallium activated sodium 
iodide crystal. The detector is coupled to a photomultiplier tube 
connected to a single channel analyzer. The activity of a gamma emitting 
radionuclide is determined from the gamma counts in the energy range for 
which the counter is set.
    Applicability: This method is applicable to the measurement of a 
single gamma emitting radionuclide. It is not applicable to mixtures of 
radionuclides. The samples counted may be in the form of particulate 
filters, absorbers, liquids or gas. The method can be applied to the 
analysis of gaseous radionuclides directly in an effluent stream by 
passing the gas stream through a chamber or cell containing the 
detector.
    3.4.4  Method G-4, Gross Gamma Counting.
    Principle: The sample is counted with a gamma detector usually a 
thallium activated sodium iodine crystal. The detector is coupled to a 
photomultiplier tube and gamma rays above a specific threshold energy 
level are counted.
    Applicability: Gross gamma measurements may be used to measure 
emissions of specific radionuclides only when it is known that the 
sample contains a single radionuclide or the identity and isotopic ratio 
of the radionuclides in the effluent stream are well known. When gross 
gamma measurements are used to determine emissions of specific 
radionuclides periodic measurements using Methods G-1 or G-2 should be 
made to demonstrate that the gross gamma measurements provide reliable 
emission data. This method may be applied to analysis of gaseous 
radionuclides directly in an effluent stream by placing the detector 
directly in or adjacent to the effluent stream or passing an extracted 
sample of the effluent stream through a chamber or cell containing the 
detector.
    3.5  Counting Methods. All of the above methods with the exception 
of Method A-5 involve counting the radiation emitted by the 
radionuclide. Counting methods applicable to the measurement of alpha, 
beta and gamma radiations are listed below. The equipment needed and the 
counting principles involved are described in detail in ASTM-3648(8).
    3.5.1  Alpha Counting:

[[Page 275]]

     Gas Flow Proportional Counters. The alpha particles cause 
ionization in the counting gas and the resulting electrical pulses are 
counted. These counters may be windowless or have very thin windows.
     Scintillation Counters. The alpha particles transfer energy 
to a scintillator resulting in a production of light photons which 
strike a photomultiplier tube converting the light photons to electrical 
pulses which are counted. The counters may involve the use of solid 
scintillation materials such as zinc sulfide or liquid scintillation 
solutions.
     Solid-State Counters. Semiconductor materials, such as 
silicon surface-barrier p-n junctions, act as solid ionization chambers. 
The alpha particles interact which the detector producing electron hole 
pairs. The charged pair is collected by an applied electrical field and 
the resulting electrical pulses are counted.
     Alpha Spectrometers. Semiconductor detectors used in 
conjunction with multichannel analyzers for energy discrimination.
    3.5.2  Beta Counting:
     Ionization Chambers. These chambers contain the beta-
emitting nuclide in gaseous form. The ionization current produced is 
measured.
     Geiger-Muller (GM) Counters-or Gas Flow Proportional 
Counters. The beta particles cause ionization in the counting gas and 
the resulting electrical pulses are counted. Proportional gas flow 
counters which are heavily shielded by lead or other metal, and provided 
with an anti-coincidence shield to reject cosmic rays, are called low 
background beta counters.
     Scintillation Counters. The beta particles transfer energy 
to a scintillator resulting in a production of light photons, which 
strike a photomultiplier tube converting the light photon to electrical 
pulses which are counted. This may involve the use of anthracene 
crystals, plastic scintillator, or liquid scintillation solutions with 
organic phosphors.
     Liquid Scintillation Spectrometers. Liquid scintillation 
counters which use two photomultiplier tubes in coincidence to reduce 
background counts. This counter may also electronically discriminate 
among pulses of a given range of energy.
    3.5.3  Gamma Counting:
     Low-Resolution Gamma Spectrometers. The gamma rays interact 
with thallium activated sodium iodide or cesium iodide crystal resulting 
in the release of light photons which strike a photomultiplier tube 
converting the light pulses to electrical pulses proportional to the 
energy of the gamma ray. Multi-channel analyzers are used to separate 
and store the pulses according to the energy absorbed in the crystal.
     High-Resolution gamma Spectrometers. Gamma rays interact 
with a lithium-drifted (Ge(Li)) or high-purity germanium (HPGe) 
semiconductor detectors resulting in a production of electron-hole 
pairs. The charged pair is collected by an applied electrical field. A 
very stable low noise preamplifier amplifies the pulses of electrical 
charge resulting from the gamma photon interactions. Multichannel 
analyzers or computers are used to separate and store the pulses 
according to the energy absorbed in the crystal.
     Single Channel Analyzers. Thallium activated sodium iodide 
crystals used with a single window analyzer. Pulses from the 
photomultiplier tubes are separated in a single predetermined energy 
range.
    3.5.4  Calibration of Counters. Counters are calibrated for specific 
radionuclide measurements using a standard of the radionuclide under 
either identical or very similar conditions as the sample to be counted. 
For gamma spectrometers a series of standards covering the energy range 
of interest may be used to construct a calibration curve relating gamma 
energy to counting efficiency.
    In those cases where a standard is not available for a radionuclide, 
counters may be calibrated using a standard with energy characteristics 
as similar as possible to the radionuclide to be measured. For gross 
alpha and beta measurements of the unidentified mixtures of 
radionuclides, alpha counters are calibrated with a natural uranium 
standard and beta counters with a cesium-137 standard. The standard must 
contain the same weight and distribution of solids as the samples, and 
be mounted in an identical manner. If the samples contain variable 
amounts of solids, calibration curves relating weight of solids present 
to counting efficiency are prepared. Standards other than those 
prescribed may be used provided it can be shown that such standards are 
more applicable to the radionuclide mixture measured.
    3.6  Radiochemical Methods for Selected Radionuclides. Methods for a 
selected list of radionuclides are listed in Table 1. The radionuclides 
listed are those which are most commonly used and which have the 
greatest potential for causing doses to members of the public. For 
radionuclides not listed in Table 1, methods based on any of the 
applicable ``principles of measurement'' described in section 3.1 
through 3.4 may be used.
    3.7  Applicability of Gross Alpha and Beta Measurements to 
Unidentified Mixtures of Radionuclides. Gross alpha and beta 
measurements may be used as a screening measurement as a part of an 
emission measurement program to identify the need to do specific 
radionuclide analyses or to confirm or verify that unexpected 
radionuclides are not being released in significant quantities.
    Gross alpha (Method A-4) or gross beta (Methods B-2 or B-4) 
measurements may also be used for the purpose of comparing the measured 
concentrations in the effluent stream with the limiting ``Concentration 
Levels for Environmental Compliance'' in

[[Page 276]]

table 2 of appendix E. For unidentified mixtures, the measured 
concentration value shall be compared with the lowest environmental 
concentration limit for any radionuclide which is not known to be absent 
from the effluent stream.

4. Quality Assurance Methods

    Each facility required to measure their radionuclide emissions shall 
conduct a quality assurance program in conjunction with the radionuclide 
emission measurements. This program shall assure that the emission 
measurements are representative, and are of known precision and accuracy 
and shall include administrative controls to assure prompt response when 
emission measurements indicate unexpectedly large emissions. The program 
shall consist of a system of policies, organizational responsibilities, 
written procedures, data quality specifications, audits, corrective 
actions and reports. This quality assurance program shall include the 
following program elements:
    4.1  The organizational structure, functional responsibilities, 
levels of authority and lines of communications for all activities 
related to the emissions measurement program shall be identified and 
documented.
    4.2  Administrative controls shall be prescribed to ensure prompt 
response in the event that emission levels increase due to unplanned 
operations.
    4.3  The sample collection and analysis procedures used in measuring 
the emissions shall be described including where applicable:
    4.3.1  Identification of sampling sites and number of sampling 
points, including the rationale for site selections.
    4.3.2  A description of sampling probes and representativeness of 
the samples.
    4.3.3  A description of any continuous monitoring system used to 
measure emissions, including the sensitivity of the system, calibration 
procedures and frequency of calibration.
    4.3.4  A description of the sample collection systems for each 
radionuclide measured, including frequency of collection, calibration 
procedures and frequency of calibration.
    4.3.5  A description of the laboratory analysis procedures used for 
each radionuclide measured, including frequency of analysis, calibration 
procedures and frequency of calibration.
    4.3.6  A description of the sample flow rate measurement systems or 
procedures, including calibration procedures and frequency of 
calibration.
    4.3.7  A description of the effluent flow rate measurement 
procedures, including frequency of measurements, calibration procedures 
and frequency of calibration.
    4.4  The objectives of the quality assurance program shall be 
documented and shall state the required precision, accuracy and 
completeness of the emission measurement data including a description of 
the procedures used to assess these parameters. Accuracy is the degree 
of agreement of a measurement with a true or known value. Precision is a 
measure of the agreement among individual measurements of the same 
parameters under similar conditions. Completeness is a measure of the 
amount of valid data obtained compared to the amount expected under 
normal conditions.
    4.5  A quality control program shall be established to evaluate and 
track the quality of the emissions measurement data against preset 
criteria. The program should include where applicable a system of 
replicates, spiked samples, split samples, blanks and control charts. 
The number and frequency of

[[Page 277]]

such quality control checks shall be identified.
    4.6  A sample tracking system shall be established to provide for 
positive identification of samples and data through all phases of the 
sample collection, analysis and reporting system. Sample handling and 
preservation procedures shall be established to maintain the integrity 
of samples during collection, storage and analysis.
    4.7  Periodic internal and external audits shall be performed to 
monitor compliance with the quality assurance program. These audits 
shall be performed in accordance with written procedures and conducted 
by personnel who do not have responsibility for performing any of the 
operations being audited.
    4.8  A corrective action program shall be established including 
criteria for when corrective action is needed, what corrective actions 
will be taken and who is responsible for taking the corrective action.
    4.9  Periodic reports to responsible management shall be prepared on 
the performance of the emissions measurements program. These reports 
should include assessment of the quality of the data, results of audits 
and description of corrective actions.
    4.10  The quality assurance program should be documented in a 
quality assurance project plan which should address each of the above 
requirements.

             Method 115--Monitoring for Radon-222 Emissions

    This appendix describes the monitoring methods which must be used in 
determining the radon-222 emissions from underground uranium mines, 
uranium mill tailings piles, phosphogypsum stacks, and other piles of 
waste material emitting radon.


[[Page 278]]


1. Radon-222 Emissions from Underground Uranium Mine Vents

    1.1  Sampling Frequency and Calculation of Emissions. Radon-222 
emissions from underground uranium mine vents shall be determined using 
one of the following methods:
    1.1.1  Continuous Measurement. These measurements shall be made and 
the emissions calculated as follows:
    (a) The radon-222 concentration shall be continuously measured at 
each mine vent whenever the mine ventilation system is operational.
    (b) Each mine vent exhaust flow rate shall be measured at least 4 
times per year.
    (c) A weekly radon-222 emission rate for the mine shall be 
calculated and recorded weekly as follows:

Aw= C1Q1T1 + 
C2Q2T2 + . . . 
CiQiTi

Where:
Aw=Total radon-222 emitted from the mine during week (Ci)
Ci=Average radon-222 concentration in mine vent i(Ci/m\3\)
Qi=Volumetric flow rate from mine vent i(m\3\/hr)
Ti=Hours of mine ventilation system operation during week for 
mine vent i(hr)

    (d) The annual radon-222 emission rate is the sum of the weekly 
emission rates during a calendar year.
    1.1.2  Periodic Measurement. This method is applicable only to mines 
that continuously operate their ventilation system except for extended 
shutdowns. Mines which start up and shut down their ventilation system 
frequently must use the continuous measurement method describe in 
Section 1.1.1 above. Emission rates determined using periodic 
measurements shall be measured and calculated as follows:
    (a) The radon-222 shall be continuously measured at each mine vent 
for at least one week every three months.
    (b) Each mine vent exhaust flow rate shall be measured at least once 
during each of the radon-222 measurement periods.
    (c) A weekly radon-222 emission rate shall be calculated for each 
weekly period according to the method described in Section 1.1.1. In 
this calculation T=168 hr.
    (d) The annual radon-222 emission rate from the mine should be 
calculated as follows:
[GRAPHIC] [TIFF OMITTED] TC15NO91.090

Where:
Ay=Annual radon-222 emission rate from the mine(Ci)
Awi=Weekly radon-222 emission rate during the measurement 
period i (Ci)
n=Number of weekly measurement periods per year
Ws=Number of weeks during the year that the mine ventilation 
system is shut down in excess of 7 consecutive days, i.e. the sum of the 
number of weeks each shut down exceeds 7 days

    1.2  Test Methods and Procedures
    Each underground mine required to test its emissions, unless an 
equivalent or alternative method has been approved by the Administrator, 
shall use the following test methods:
    1.2.1  Test Method 1 of appendix A to part 60 shall be used to 
determine velocity traverses. The sampling point in the duct shall be 
either the centroid of the cross section or the point of average 
velocity.
    1.2.2  Test Method 2 of appendix A to part 60 shall be used to 
determine velocity and volumetric flow rates.
    1.2.3  Test Methods A-6 or A-7 of appendix B, Method 114 to part 61 
shall be used for the analysis of radon-222. Use of Method A-7 requires 
prior approval of EPA based on conditions described in appendix B.
    1.2.4  A quality assurance program shall be conducted in conformance 
with the programs described for Continuous Radon Monitors and Alpha 
Track Detectors in EPA 520/1-89-009. (2)

2. Radon-222 Emissions from Uranium Mill Tailings Piles

    2.1  Measurement and Calculation of Radon Flux from Uranium Mill 
Tailings Piles.
    2.1.1  Frequency of Flux Measurement. A single set of radon flux 
measurements may be made, or if the owner or operator chooses, more 
frequent measurements may be made over a one year period. These 
measurements may involve quarterly, monthly or weekly intervals. All 
radon measurements shall be made as described in paragraphs 2.1.2 
through 2.1.6 except that for measurements made over a one year period, 
the requirement of paragraph 2.1.4(c) shall not apply. The mean radon 
flux from the pile shall be the arithmetic mean of the mean radon flux 
for each measurement period. The weather conditions, moisture content of 
the tailings and area of the pile covered by water existing at the time 
of the measurement shall be chosen so as to provide measurements 
representative of the long term radon flux from the pile and shall be 
subject to EPA review and approval.
    2.1.2  Distribution of Flux Measurements. The distribution and 
number of radon flux measurements required on a pile will depend on 
clearly defined areas of the pile (called regions) that can have 
significantly different radon fluxes due to surface conditions. The mean 
radon flux shall be determined for each individual region of the pile. 
Regions that shall be considered for operating mill tailings piles are:

    (a) Water covered areas,

[[Page 279]]

    (b) Water saturated areas (beaches),
    (c) Dry top surface areas, and
    (d) Sides, except where earthen material is used in dam 
construction.

    For mill tailings after disposal the pile shall be considered to 
consist of only one region.
    2.1.3  Number of Flux Measurements. Radon flux measurements shall be 
made within each region on the pile, except for those areas covered with 
water. Measurements shall be made at regularly spaced locations across 
the surface of the region, realizing that surface roughness will 
prohibit measurements in some areas of a region. The minimum number of 
flux measurements considered necessary to determine a representative 
mean radon flux value for each type of region on an operating pile is:

    (a) Water covered area--no measurements required as radon flux is 
assumed to be zero,
    (b) Water saturated beaches--100 radon flux measurements,
    (c) Loose and dry top surface--100 radon flux measurements,
    (d) Sides--100 radon flux measurements, except where earthern 
material is used in dam construction.

    For a mill tailings pile after disposal which consists of only one 
region a minimum of 100 measurements are required.
    2.1.4  Restrictions to Radon Flux Measurements. The following 
restrictions are placed on making radon flux measurements:

    (a) Measurements shall not be initiated within 24 hours of a 
rainfall.
    (b) If a rainfall occurs during the 24 hour measurements period, the 
measurement is invalid if the seal around the lip of the collector has 
washed away or if the collector is surrounded by water.
    (c) Measurements shall not be performed if the ambient temperature 
is below 35  deg.F or if the ground is frozen.

    2.1.5  Areas of Pile Regions. The approximate area of each region of 
the pile shall be determined in units of square meters.
    2.1.6  Radon Flux Measurement. Measuring radon flux involves the 
adsorption of radon on activated charcoal in a large-area collector. The 
radon collector is placed on the surface of the pile area to be measured 
and allowed to collect radon for a time period of 24 hours. The radon 
collected on the charcoal is measured by gamma-ray spectroscopy. The 
detailed measurement procedure provided in appendix A of EPA 520/5-85-
0029(1) shall be used to measure the radon flux on uranium mill 
tailings, except the surface of the tailings shall not be penetrated by 
the lip of the radon collector as directed in the procedure, rather the 
collector shall be carefully positioned on a flat surface with soil or 
tailings used to seal the edge.
    2.1.7  Calculations. The mean radon flux for each region of the pile 
and for the total pile shall be calculated and reported as follows:

    (a) The individual radon flux calculations shall be made as provided 
in appendix A EPA 86 (1). The mean radon flux for each region of the 
pile shall be calculated by summing all individual flux measurements for 
the region and dividing by the total number of flux measurements for the 
region.
    (b) The mean radon flux for the total uranium mill tailings pile 
shall be calculated as follows.
[GRAPHIC] [TIFF OMITTED] TC15NO91.091

Where:
Js=Mean flux for the total pile (pCi/m2-s)
Ji=Mean flux measured in region i (pCi/m2-s)
Ai=Area of region i (m2)
At=Total area of the pile (m2)

    2.1.8  Reporting. The results of individual flux measurements, the 
approximate locations on the pile, and the mean radon flux for each 
region and the mean radon flux for the total stack shall be included in 
the emission test report. Any condition or unusual event that occurred 
during the measurements that could significantly affect the results 
should be reported.
    3.0  Radon-222 Emissions from Phosphogypsum Stacks.
    3.1  Measurement and Calculation of the Mean Radon Flux. Radon flux 
measurements shall be made on phosphogypsum stacks as described below:
    3.1.1  Frequency of Measurements. A single set of radon flux 
measurements may be made after the phosphogypsum stack becomes inactive, 
or if the owner or operator chooses, more frequent measurements may be 
made over a one year period. These measurements may involve quarterly, 
monthly or weekly intervals. All radon measurements shall be made as 
described in paragraphs 3.1.2 through 3.1.6 except that for measurements 
made over a one year period, the requirement of paragraph 3.1.4(c) shall 
not apply. For measurements made over a one year period, the radon flux 
shall be the arithmetic mean of the mean radon flux for each measurement 
period.
    3.1.2  Distribution and Number of Flux Measurements. The 
distribution and number of radon flux measurements required on a stack 
will depend on clearly defined areas of the stack (called regions) that 
can have significantly different radon fluxes due to surface conditions. 
The mean radon flux shall be determined for each individual region of 
the stack. Regions that shall be considered are:

    (a) Water covered areas,
    (b) Water saturated areas (beaches),

[[Page 280]]

    (c) Loose and dry top surface areas,
    (d) Hard-packed roadways, and
    (e) Sides.

    3.1.3  Number of Flux Measurements. Radon flux measurements shall be 
made within each region on the phosphogypsum stack, except for those 
areas covered with water. Measurements shall be made at regularly spaced 
locations across the surface of the region, realizing that surface 
roughness will prohibit measurements in some areas of a region. The 
minimum number of flux measurements considered necessary to determine a 
representative mean radon flux value for each type of region is:

    (a) Water covered area--no measurements required as radon flux is 
assumed to be zero,
    (b) Water saturated beaches--50 radon flux measurements,
    (c) Loose and dry top surface--100 radon flux measurements,
    (d) Hard-packed roadways--50 radon flux measurements, and
    (e) Sides--100 radon flux measurements.

A minimum of 300 measurements are required. A stack that has no water 
cover can be considered to consist of two regions, top and sides, and 
will require a minimum of only 200 measurements.
    3.1.4  Restrictions to Radon Flux Measurements. The following 
restrictions are placed on making radon flux measurements:

    (a) Measurements shall not be initiated within 24 hours of a 
rainfall.
    (b) If a rainfall occurs during the 24 hour measurement period, the 
measurement is invalid if the seal around the lip of the collector has 
washed away or if the collector is surrounded by water.
    (c) Measurements shall not be performed if the ambient temperature 
is below 35  deg.F or if the ground is frozen.

    3.1.5  Areas of Stack Regions. The approximate area of each region 
of the stack shall be determined in units of square meters.
    3.1.6  Radon Flux Measurements. Measuring radon flux involves the 
adsorption of radon on activated charcoal in a large-area collector. The 
radon collector is placed on the surface of the stack area to be 
measured and allowed to collect radon for a time period of 24 hours. The 
radon collected on the charcoal is measured by gamma-ray spectroscopy. 
The detailed measurement procedure provided in appendix A of EPA 520/5-
85-0029(1) shall be used to measure the radon flux on phosphogypsum 
stacks, except the surface of the phosphogypsum shall not be penetrated 
by the lip of the radon collector as directed in the procedure, rather 
the collector shall be carefully positioned on a flat surface with soil 
or phosphogypsum used to seal the edge.
    3.1.7  Calculations. The mean radon flux for each region of the 
phosphogypsum stack and for the total stack shall be calculated and 
reported as follows:

    (a) The individual radon flux calculations shall be made as provided 
in appendix A EPA 86 (1). The mean radon flux for each region of the 
stack shall be calculated by summing all individual flux measurements 
for the region and dividing by the total number of flux measurements for 
the region.
    (b) The mean radon flux for the total phosphogypsum stack shall be 
calculated as follows.
[GRAPHIC] [TIFF OMITTED] TC15NO91.092

Where:
Js=Mean flux for the total stack (pCi/m2-s)
Ji=Mean flux measured in region i (pCi/m2-s)
Ai=Area of region i (m2)
At=Total area of the stack

    3.1.8  Reporting. The results of individual flux measurements, the 
approximate locations on the stack, and the mean radon flux for each 
region and the mean radon flux for the total stack shall be included in 
the emission test report. Any condition or unusual event that occurred 
during the measurements that could significantly affect the results 
should be reported.
    4.0  Quality Assurance Procedures for Measuring Rn-222 Flux

                         A. Sampling Procedures

    Records of field activities and laboratory measurements shall be 
maintained. The following information shall be recorded for each 
charcoal canister measurement:

(a) Site
(b) Name of pile
(c) Sample location
(d) Sample ID number
(e) Date and time on
(f) Date and time off
(g) Observations of meteorological conditions and comments

    Records shall include all applicable information associated with 
determining the sample measurement, calculations, observations, and 
comments.

                            B. Sample Custody

    Custodial control of all charcoal samples exposed in the field shall 
be maintained in accordance with EPA chain-of-custody field procedures. 
A control record shall document all custody changes that occur between 
the field and laboratory personnel.

                 C. Calibration Procedures and Frequency

    The radioactivity of two standard charcoal sources, each containing 
a carefully determined quantity of radium-226 uniformly distributed 
through 180g of activated charcoal,

[[Page 281]]

shall be measured. An efficiency factor is computed by dividing the 
average measured radioactivity of the two standard charcoal sources, 
minus the background, in cpm by the known radioactivity of the charcoal 
sources in dpm. The same two standard charcoal sources shall be counted 
at the beginning and at the end of each day's counting as a check of the 
radioactivity counting equipment. A background count using unexposed 
charcoal should also be made at the beginning and at the end of each 
counting day to check for inadvertent contamination of the detector or 
other changes affecting the background. The unexposed charcoal 
comprising the blank is changed with each new batch of charcoal used.

            D. Internal Quality Control Checks and Frequency

    The charcoal from every tenth exposed canister shall be recounted. 
Five percent of the samples analyzed shall be either blanks (charcoal 
having no radioactivity added) or samples spiked with known quantities 
of radium-226.

              E. Data Precision, Accuracy, and Completeness

    The precision, accuracy, and completeness of measurements and 
analyses shall be within the following limits for samples measuring 
greater than 1.0 pCi/m\2\-s.
    (a) Precision: 10%
    (b) Accuracy: 10%
    (c) Completeness: at least 85% of the measurements must yield 
useable results.

           Appendix C to Part 61--Quality Assurance Procedures

 Procedure 1--Determination of Adequate Chromatographic Peak Resolution

    In this method of dealing with resolution, the extent to which one 
chromatographic peak overlaps another is determined.
    For convenience, consider the range of the elution curve of each 
compound as running from -2 to +2. This range is used 
in other resolution criteria, and it contains 95.45 percent of the area 
of a normal curve. If two peaks are separated by a known distance, b, 
one can determine the fraction of the area of one curve that lies within 
the range of the other. The extent to which the elution curve of a 
contaminant compound overlaps the curve of a compound that is under 
analysis is found by integrating the contaminant curve over the limits 
b-2s to b+2s, where s is the standard 
deviation of the sample curve.
    This calculation can be simplified in several ways. Overlap can be 
determined for curves of unit area; then actual areas can be introduced. 
Desired integration can be resolved into two integrals of the normal 
distribution function for which there are convenient calculation 
programs and tables. An example would be Program 15 in Texas Instruments 
Program Manual ST1, 1975, Texas Instruments, Inc., Dallas, Texas 75222.

[[Page 282]]

[GRAPHIC] [TIFF OMITTED] TC01MY92.034

    In judging the suitability of alternate GC columns or the effects of 
altering chromatographic conditions, one can employ the area overlap as 
the resolution parameter with a specific maximum permissible value.

[[Page 283]]

    The use of Gaussian functions to describe chromatographic elution 
curves is widespread. However, some elution curves are highly 
asymmetric. In cases where the sample peak is followed by a contaminant 
that has a leading edge that rises sharply but the curve then tails off, 
it may be possible to define an effective width for tc as 
``twice the distance from the leading edge to a perpendicular line 
through the maxim of the contaminant curve, measured along a 
perpendicular bisection of that line.''

          Procedure 2--Procedure for Field Auditing GC Analysis

    Responsibilities of audit supervisor and analyst at the source 
sampling site include the following:
    A. The audit supervisor verifies that audit cylinders are stored in 
a safe location both before and after the audit to prevent vandalism.
    B. At the beginning and conclusion of the audit, the analyst records 
each cylinder number and pressure. An audit cylinder is never analyzed 
when the pressure drops below 200 psi.
    C. During the audit, the analyst performs a minimum of two 
consecutive analyses of each audit cylinder gas. The audit must be 
conducted to coincide with the analysis of source test samples, normally 
immediately after GC calibration and prior to sample analyses.
    D. At the end of audit analyses, the audit supervisor requests the 
calculated concentrations from the analyst and compares the results with 
the actual audit concentrations. If each measured concentration agrees 
with the respective actual concentration within plus-minus10 
percent, he directs the analyst to begin analyzing source samples. Audit 
supervisor judgment and/or supervisory policy determine action when 
agreement is not within plus-minus10 percent. When a 
consistent bias in excess of 10 percent is found, it may be possible to 
proceed with the sample analysis, with a corrective factor to be applied 
to the results at a later time. However, every attempt should be made to 
locate the cause of the discrepancy, as it may be misleading. The audit 
supervisor records each cylinder number, cylinder pressure (at the end 
of the audit), and all calculated concentrations. The individual being 
audited must not under any circumstance be told actual audit

  Appendix D to Part 61--Methods for Estimating Radionuclide Emissions

                        1. Purpose and Background

    Facility owners or operators may estimate radionuclide emissions to 
the atmosphere for dose calculations instead of measuring emissions. 
Particulate emissions from mill tailings piles should be estimated using 
the procedures listed in reference re num;2. All other emissions may be 
estimated by using

[[Page 284]]

the ``Procedures'' listed below, or using the method described in 
reference 1.

                              2. Procedure

    To estimate emissions to the atmosphere:
    (a) Determine the amount (in curies) used at facilities for the 
period under consideration. Radioactive materials in sealed packages 
that remain unopened, and have not leaked during the assessment period 
should not be included in the calculation.
    (b) Multiply the amount used by the following factors which depend 
on the physical state of the radionuclide. They are:
    (i) 1 for gases;
    (ii) 10-3 for liquids or particulate solids; and
    (iii) 10-6 for solids.
    If any nuclide is heated to a temperature of 100 degrees Celsius or 
more, boils at a temperature of 100 degrees Celsius or less, or is 
intentionally dispersed into the environment, it must be considered to 
be a gas.
    (c) If a control device is installed between the place of use and 
the point of release, multiply emissions from (b) by an adjustment 
factor. These are presented in Table 1.

  Appendix E to Part 61--Compliance Procedures Methods for Determining 
                        Compliance With Subpart I

                        1. Purpose and Background

    This Appendix provides simplified procedures to reduce the burden on 
Nuclear Regulatory Commission (NRC) licensees, and non-Department of 
Energy Federal facilities in determining compliance with 40 CFR part 61, 
subpart I. The procedures consist of a series of increasingly more 
stringent steps, depending on the facility's potential to exceed the 
standard.
    First, a facility can be found in compliance if the quantity of 
radioactive material possessed during the year is less than that listed 
in a table of annual possession quantities. A facility will also be in 
compliance if the average annual radionuclide emission concentration is 
less than that listed in a table of air concentration levels. If the 
facility is not in compliance by these tables, it can establish 
compliance by estimating a dose using screening procedure developed by 
the National Council on Radiation Protection and Measurements with a 
radiological source term derived using EPA approved emission factors. 
These procedures are described in a ``Guide for Determining Compliance 
with the

[[Page 285]]

Clean Air Act Standards for Radionuclide Emissions From NRC-Licenced and 
Non-DOE Federal Facilities.''
    A user-friendly computer program called COMPLY has been developed to 
reduce the burden on the regulated community. The Agency has also 
prepared a ``User's Guide for the COMPLY Code'' to assist the regulated 
community in using the code, and in handling more complex situations 
such as multiple release points. The basis for these compliance 
procedures are provided in ``Background Information Document: Procedures 
Approved for Demonstrating Compliance with 40 CFR Part 61, Subpart I''. 
The compliance model is the highest level in the COMPLY computer code 
and provides for the most realistic assessment of dose by allowing the 
use of site-specific information.

                 2. Table of Annual Possession Quantity

    (a) Table 1 may be used for determining if facilities are in 
compliance with the standard. The possession table can only be used if 
the following conditions are met:
    (i) No person lives within 10 meters of any release point; and
    (ii) No milk, meat, or vegetables are produced within 100 meters of 
any release point.
    (b) Procedures described in Reference (1) shall be used to determine 
compliance or exemption from reporting by use of Table 2.

*Radionuclides boiling at 100  deg.C or less, or exposed to a
  temperature of 100  deg.C, must be considered a gas. Capsules
  containing radionuclides in liquid or powder form can be considered to
  be solids.
**Mo-99 contained in a generator to produce Technetium-99 can be assumed
  to be a solid.

                    3. Table of Concentration Levels

    (a) Table 2 may be used for determining if facilities are in 
compliance with the standard.
    1. The concentration table as applied to emission estimates can only 
be used if all releases are from point sources and concentrations have 
been measured at the stack or vent using EPA-approved methods, and the 
distance between each stack or vent and the nearest resident is greater 
than 3 times the diameter of the stack or vent. Procedures provided in 
Ref. (1) shall be used to determine compliance or exemption from 
reporting by use of Table 2.
    2. The concentration table may be used to determine compliance with 
the standard based on environmental measurements provided these 
measurements are made in conformance with the requirements of

    The procedures described in Reference (4) may be used to determine 
doses to members of the general public from emissions of radionuclides 
to the atmosphere. Both the total dose from all radionuclides emitted, 
and the dose caused by radioactive iodine must be considered in 
accordance with the procedures in Ref. (1).

                       5. The COMPLY Computer Code

    The COMPLY computer code may be used to determine compliance with 
subpart I. The compliance model in the COMPLY computer code may be used 
to determine the dose to members of the general public from emissions of 
radionuclides to the atmosphere. The EPA may add radionuclides to all or 
any part of COMPLY to cover radionuclides that may be used by the 
regulated community.

                      Subpart A--General Provisions



Sec. 62.01  Definitions.

    As used in this part, all terms not defined herein shall have the 
meaning given to them in the Clean Air Act and in part 60 of this 
chapter.



Sec. 62.02  Introduction.

    (a) This part sets forth the Administrator's approval and 
disapproval of State plans for the control of pollutants and facilities 
under section 111(d), and section 129 as applicable, of the Act, and the 
Administrator's promulgation of such plans or portions of plans thereof. 
Approval of a plan or any portion of a plan is based on a determination 
by the Administrator that it meets the requirements of section 111(d), 
and section 129 as applicable, of the Act and provisions of part 60 of 
this chapter.
    (b) If a State does not submit a complete, approvable plan, the 
Administrator may then promulgate a substitute plan or part of a plan. 
The promulgated provision, plus the approved parts of the State plan, 
constitute the applicable plan for purposes of the act.
    (c) The Administrator will promulgate substitute provisions for the 
disapproved regulatory provisions only. If a nonregulatory provision is 
disapproved, however, it will be noted in this part and a detailed 
explanation will be sent to the State.
    (d) All approved regulatory provisions of each plan are incorporated 
by reference in this part. Section 62.12 provides information on 
availability of applicable plans. The Administrator and State and local 
agencies shall enforce (1) regulatory provisions of a plan approved or 
promulgated by the Administrator, and (2) all permit conditions or 
denials issued in carrying out the approved or promulgated regulations 
for the review of designated facilities.
    (e) Each State's plan is dealt with in a separate subpart, with 
separate headings for different pollutants and facilities. The plans 
shall include an introductory section identifying the plan by name and 
the date of its submittal. Additional sections are included as necessary 
to specifically identify disapproved provisions, to set forth reasons 
for disapproval, and to set forth provisions of the plan promulgated by 
the Administrator. Except as otherwise specified, all supplemental 
information submitted to the Administrator with respect to any plan has 
been submitted by the Governor of the State.
    (f) Revisions to applicable plans will be included in this part when 
approved or promulgated by the Administrator.
    (g) Substitute plans promulgated by the Administrator for States 
that do not have approved plans are contained in separate subparts that 
appear after the subparts for States. These Federal plans include 
sections identifying the applicability of the plan, emission limits, 
compliance schedules, recordkeeping and reporting, performance testing, 
and monitoring requirements.

[43 FR 51393, Nov. 3, 1978, as amended at 63 FR 63201, Nov. 12, 1998]



Sec. 62.03  Extensions.

    The Administrator may, whenever he determines necessary, extend the 
period for submission of any plan or plan revision or portion thereof.



Sec. 62.04  Approval status.

    The approval status of each State's plan or portions thereof, are 
set forth in each subpart. All plans are approved unless specifically 
disapproved in the appropriate subpart.



Sec. 62.05  Legal authority.

    (a) The Administrator's determination of the absence or inadequacy 
of

[[Page 306]]

legal authority required to be included in the plan is set forth in each 
subpart. This includes the legal authority of local agencies and State 
governmental agencies other than an air pollution control agency if such 
other agencies are assigned responsibility for carrying out a plan or 
portion thereof.
    (b) No legal authority as such is promulgated by the Administrator. 
Where required regulatory provisions are not included in the plan by the 
State because of inadequate authority, substitute provisions are 
promulgated by the Administrator.



Sec. 62.06  Negative declarations.

    A State may submit to the Administrator a letter certifying that no 
designated facilities exist in the State if such is the case. The 
negative declaration will be in lieu of a plan.



Sec. 62.07  Emission standards, compliance schedules.

    (a) In each subpart, emission standards and compliance schedules 
which have been disapproved by the Administrator are identified, and 
those promulgated by the Administrator are set forth.
    (b) The Administrator's approval or promulgation of any compliance 
schedule shall not affect the responsibility of the owner or operator to 
comply with any applicable emission limitation on or after the date for 
final compliance specified in the applicable schedule.



Sec. 62.08  Emission inventories and source surveillance.

    (a) Each subpart identifies the plan provisions for source 
surveillance which are disapproved, and sets forth the Administrator's 
promulgation of necessary provisions for requiring designated sources to 
maintain records, make reports, and submit information.
    (b) The Administrator will not promulgate provisions for disapproved 
State or local agency procedures for testing, inspection, investigation, 
or detection. However, detailed critiques of such portions will be 
provided to the State.



Sec. 62.09  Revision of plans by Administrator.

    After notice and opportunity for public hearing in each affected 
State, the Administrator may revise any provision of an applicable plan 
if:
    (a) The provision was promulgated by the Administrator and
    (b) The plan, as revised, will be consistent with the Act and with 
the requirements of part 60, subpart B of this chapter.



Sec. 62.10  Submission to Administrator.

    Except as otherwise provided in Sec. 60.23 of this chapter, all 
requests, reports, applications, submittals, and other communications to 
the Administrator pursuant to this part shall be submitted in duplicate

Sec. 62.14109  Reporting and recordkeeping and compliance and performance testing.

    (a) The owner or operator of an affected facility must comply with 
the reporting and recordkeeping provisions listed in 40 CFR 60.59b of 
subpart Eb, except as provided in paragraphs (a)(1) through (a)(3) of 
this section.
    (1) The siting requirements under 40 CFR 60.59b(a), (b)(5), and 
(d)(11) of subpart Eb and the notification of construction requirements 
under 40 CFR 60.59b(b) and (c) of subpart Eb do not apply.
    (2) 40 CFR 60.54b, 60.56b, and 60.58b(g)(5)(iii) of subpart Eb do 
not apply to this subpart (see Secs. 62.14105 and 62.14107 of this 
subpart).
    (b) The owner or operator of an affected facility must comply with 
the compliance and performance testing methods and procedures listed in 
40 CFR 60.58b of subpart Eb, except as provided in paragraphs (c) and 
(d) of this section.
    (c) The initial performance test must be completed within 180 days 
after the date of final compliance specified in Sec. 62.14108, rather 
than the date for the initial performance test specified in 40 CFR 
60.58b of subpart Eb.
    (d) The owner or operator of an affected facility may follow the 
alternative performance testing schedule for dioxin/furan emissions 
specified in paragraph (d)(1) of this section.
    (1) If all performance tests for all affected facilities at the MWC 
plant over a 2-year period indicate that dioxin/furan emissions are less 
than or equal to 15 nanograms per dry standard cubic meter total mass, 
corrected to 7 percent oxygen for all affected facilities

[[Page 367]]

located within a municipal waste combustor plant, the owner or operator 
of the municipal waste combustor plant may elect to conduct annual 
performance tests for one affected facility (i.e., unit) per year at the 
municipal waste combustor plant. At a minimum, a performance test for 
dioxin/furan emissions shall be conducted annually (no more than 12 
months following the previous performance test) for one affected 
facility at the municipal waste combustor plant. Each year a different 
affected facility at the municipal waste combustor plant shall be 
tested, and the affected facilities at the plant shall be tested in 
sequence (e.g., unit 1, unit 2, unit 3, as applicable). If each annual 
performance test continues to indicate a dioxin/furan emission level 
less than or equal to 15 nanograms per dry standard cubic meter (total 
mass), the owner or operator may continue conducting a performance test 
on only one affected facility per year. If any annual performance test 
indicates a dioxin/furan emission level greater than 15 nanograms per 
dry standrd cubic meter (total mass), performance tests thereafter shall 
be conducted annually on all affected facilities at the plant until and 
unless all annual performance tests for all affected facilities at the 
plant over a 2-year period indicate a dioxin/furan emission level less 
than or equal to 15 nanograms per dry standard cubic meter (total mass).
    (2) The owner or operator who is following the alternative 
performance testing schedule for dioxin/furan emissions specified in 
paragraph (d)(1) of this section may choose an alternative testing 
sequence (e.g., unit 1, 3, 2, 4) for affected facilities at the 
municipal waste combustor plant. The owner or operator must submit a 
request to EPA for approval of the alternative testing sequence. After 
approval, the alternative testing sequence is effective until a 
different testing sequence is received and approved by EPA.
    (e) The owner or operator of an affected facility that is taking 
longer than 1 year after the date of publication of this subpart FFF 
final rule to comply with the emission limits of this subpart must 
submit notification to the EPA Regional Office within 10 business days 
of completing each increment. Each notification must indicate which 
increment of progress specified in Sec. 62.14108(a)(1) through (a)(5) 
has been achieved. The notification must be signed by the owner or 
operator of the affected facility.
    (f) The owner or operator of an affected facility that is taking 
longer than 1 year after the date of publication of this subpart FFF to 
comply with the emission limits of this subpart who fails to meet any 
increment of progress specified in Sec. 62.14108(a)(1) through (a)(5) 
according to the applicable schedule in Sec. 62.14108 must submit 
notification to the EPA Regional Office within 10 business days of the 
applicable date in Sec. 62.14108 that the owner or operator failed to 
meet the increment.
    (g) The owner or operator of an affected facility that is taking 
longer than 1 year after the date of publication of this subpart FFF to 
comply with the emission limits of this subpart must submit a final 
control plan by the date specified in Sec. 62.14108(b) with the 
notification required by Sec. 62.14109(e). The final control plan must, 
at a minimum, include a description of the air pollution control devices 
or process changes that will be employed for each unit to comply with 
the emission limits and other requirements of this subpart.
    (h) The owner or operator of an affected facility that is taking 
longer than 1 year after the date of publication of this subpart FFF to 
comply with the emission limits of this subpart must submit a signed 
copy of the contract or contracts awarded according to the requirements 
of Sec. 62.14108(a)(2) with the notification required by 
Sec. 62.14109(e).
    (i) The owner or operator of an affected facility that is taking 
longer than 1 year after the date of publication of this subpart FFF to 
comply with the emission limits of this subpart must keep on site a copy 
of the final control plan required by Sec. 62.14109(g).
    (j) The owner or operator of an affected facility that plans to 
cease operation of the affected facility on or before December 19, 2000 
rather than comply with the emission limits of this subpart by the 
applicable compliance

[[Page 368]]

 date specified in Sec. 62.14108 must submit a notification by the date 
specified for the final control plan according to the schedule specified 
in paragraphs Sec. 62.14108(b)(1) through (b)(4), as applicable. 
(Affected facilities that cease operation on or before December 19, 2000 
rather than comply with the emission limits of this subpart by the 
compliance date specified in Sec. 62.14108 are not required to submit a 
final control plan.) The notification must state the date by which the 
affected facility will cease operation. If the cease operation date is 
later than 1 year after the date of publication of this subpart FFF, the 
owner or operator must enter into a legally binding closure agreement 
with EPA by the date the final control plan is due. The agreement must 
specify the date by which operation will cease.
    (k) The owner or operator of an affected facility that plans to de-
rate the affected facility on or before December 19, 2000 rather than 
comply with the emission limits of this subpart by the compliance date 
specified in Sec. 62.14108 must submit a final control plan as required 
by paragraph (g) of this section and submit notification of increments 
of progress as required by paragraphs (e) and (f) of this section and 
Sec. 62.14108(e) of this subpart.
    (1) The final control plan must, at a minimum, include the 
information in paragraphs (k)(1)(i) and (k)(1)(ii) of this section 
rather than the information in paragraph (g) of this section.
    (i) A description of the physical changes that will be made to 
accomplish the de-rating.
    (ii) Calculations of the current maximum combustion capacity and the 
planned maximum combustion capacity after the de-rating. (See the 
procedures specified in 40 CFR 60.58b(j) of subpart Eb for calculating 
municipal waste combustor unit capacity.)
    (2) The owner or operator must submit a signed copy of the contract 
or contracts awarded to initiate the de-rating with the notification 
required by paragraph (e) of this section.
    (l) The owner or operator of an affected facility that is ceasing 
operation more than 1 year following the date of publication of this 
subpart FFF must submit performance test results for dioxin/furan 
emissions conducted during or after 1990 for each affected facility by 
the date 1 year after the date of publication of this subpart FFF. The 
performance test shall be conducted according to the procedure in 
paragraph (b) of this section.
    (m) The owner or operator (or the State air pollution control 
authority) that is submitting alternative dates for increments 2, 3, and 
4 according to Sec. 62.14108(b)(4) must submit the alternative dates by 
the date specified for the final control plan according to the schedule 
specified in paragraphs Sec. 62.14108 (b)(1) and (b)(2), as applicable. 
The owner or operator (or the State air pollution control authority)

    Subpart GGG--Federal Plan Requirements for Municipal Solid Waste 
Landfills That Commenced Construction Prior to May 30, 1991 and Have Not 
            Been Modified or Reconstructed Since May 30, 1991

    Source: 64 FR 60703, Nov. 8, 1999, unless otherwise noted.



Sec. 62.14350  Scope and delegation of authority.

    (a) This subpart contains emission requirements and compliance 
schedules for the control of designated pollutants from certain 
municipal solid waste landfills in accordance with section 111(d) of the 
Clean Air Act and 40 CFR part 60, subpart B. This municipal solid waste 
landfills Federal plan applies to each designated facility as defined in 
Sec. 62.14352 of this subpart that is not covered by an EPA approved and 
currently effective State or Tribal plan.
    (b) The following authorities shall be retained by the Administrator 
and not transferred to the State or Tribe upon delegation of authority 
to the State or Tribe to implement and enforce the Federal plan pursuant 
to sections 101(a)(3) and 111 of the Clean Air Act:
    (1) Approval of alternative methods to determine site-specific NMOC 
concentration (C NMOC) or site-specific methane generation 
rate constant (k) used in calculating the annual NMOC emission rate (as 
provided in 40 CFR 60.754(a)(5) of subpart WWW),
    (2) Alternative emission standards,
    (3) Major alternatives 1 to test methods,
---------------------------------------------------------------------------

    \1\ Major changes to test methods or to monitoring are modifications 
made to a federally enforceable test method or to a federal monitoring 
requirement. These changes would involve the use of unproven technology 
or procedures or an entirely new method (which is sometimes necessary 
when the required test method or monitoring requirement is unsuitable).
---------------------------------------------------------------------------

    (4) Major alternatives to monitoring, or
    (5) Waivers of recordkeeping.



Sec. 62.14351  Definitions.

    Terms used but not defined in this subpart have the meaning given 
them in the Clean Air Act and 40 CFR part 60, subparts A, B, and WWW.
    Achieve final compliance means to connect and operate the collection 
and control system as specified in the final control plan. Within 180 
days after the date the landfill is required to achieve final 
compliance, the initial performance test must be conducted.
    Award contract means the MSW landfill owner or operator enters into 
legally binding agreements or contractual obligations that cannot be 
canceled or modified without substantial financial loss to the MSW 
landfill owner or operator. The MSW landfill owner or operator may award 
a number of contracts to install the collection and control system. To 
meet this increment of progress, the MSW landfill owner or operator must 
award a contract or contracts to initiate on-site construction or 
installation of the collection and control system.
    Complete on-site construction means that all necessary collection 
system

[[Page 373]]

components and air pollution control devices identified in the final 
control plan are on site, in place, and ready for operation.
    Design capacity means the maximum amount of solid waste a landfill 
can accept, as indicated in terms of volume or mass in the most recent 
permit issued by the State, local, or Tribal agency responsible for 
regulating the landfill, plus any in-place waste not accounted for in 
the most recent permit. If the owner or operator chooses to convert the 
design capacity from volume to mass or from mass to volume to 
demonstrate its design capacity is less than 2.5 million megagrams or 
2.5 million cubic meters, the calculation must include a site-specific 
density, which must be recalculated annually.
    EPA approved State plan means a State plan that EPA has approved 
based on the requirements in 40 CFR part 60, subpart B to implement and 
enforce 40 CFR part 60, subpart Cc. An approved State plan becomes 
effective on the date specified in the notice published in the Federal 
Register announcing EPA's approval.
    Federal Indian Reservation means for purposes of the Clean Air Act, 
all land within the limits of any Indian reservation under the 
jurisdiction of the United States government, notwithstanding the 
issuance of any patent, and including rights-of-way running through the 
reservation.
    Final control plan (Collection and control system design plan) means 
a plan that describes the collection and control system that will 
capture the gas generated within an MSW landfill. The collection and 
control system design plan must be prepared by a professional engineer 
and must describe a collection and control system that meets the 
requirements of 40 CFR 60.752(b)(2)(ii). The final control plan must 
contain engineering specifications and drawings of the collection and 
control system. The final control plan must include any alternatives to 
the operational standards, test methods, procedures, compliance 
measures, monitoring, recordkeeping or reporting provisions of 40 CFR 
60.753 through 60.758 proposed by the owner or operator. The final 
control plan must either conform with the specifications for active 
collection systems in 40 CFR 60.759 or include a demonstration that 
shows that based on the size of the landfill and the amount of waste 
expected to be accepted, the system is sized properly to collect the 
gas, control emissions of NMOC to the required level and meet the 
operational standards for a landfill.
    Indian Country means all land within the limits of any Indian 
reservation under the jurisdiction of the United States government, 
notwithstanding the issuance of any patent, and including rights-of-way 
running through the reservation; all dependent Indian communities within 
the borders of the United States whether within the original or 
subsequently acquired territory thereof, and whether within or without 
the limits of a State; and all Indian allotments, the Indian titles to 
which have not been extinguished, including rights-of-way running 
through the same.
    Initiate on-site construction means to begin any of the following: 
installation of the collection and control system to be used to comply 
with the emission limits as outlined in the final control plan; physical 
preparation necessary for the installation of the collection and control 
system to be used to comply with the final emission limits as outlined 
in the final control plan; or, alteration of an existing collection and 
control system to be used to comply with the final emission limits as 
outlined in the final control plan.
    Modification means an increase in the permitted volume design 
capacity of the landfill by either horizontal or vertical expansion 
based on its permitted design capacity as of May 30, 1991. Modification 
does not occur until the owner or operator commences construction on the 
horizontal or vertical expansion.
    Municipal solid waste landfill or MSW landfill means an entire 
disposal facility in a contiguous geographical space where household 
waste is placed in or on land. A municipal solid waste landfill may also 
receive other types of RCRA Subtitle D wastes such as commercial solid 
waste, nonhazardous sludge, conditionally exempt small

[[Page 374]]

quantity generator waste, and industrial solid waste. Portions of a 
municipal solid waste landfill may be separated by access roads. A 
municipal solid waste landfill may be publicly or privately owned.
    Negative declaration letter means a letter to EPA declaring that 
there are no existing MSW landfills in the State or that there are no 
existing MSW landfills in the State that must install collection and 
control systems according to the requirements of 40 CFR part 60, subpart 
Cc. The negative declaration letter must include the design capacities 
of any existing MSW landfills with a design capacity less than 2.5 
million megagrams or 2.5 million cubic meters.
    Protectorate means American Samoa, the Commonwealth of Puerto Rico, 
the District of Columbia, Guam, the Northern Mariana Islands, and the 
Virgin Islands.
    State means any of the 50 United States and the protectorates of the 
United States.
    State plan means a plan submitted pursuant to section 111(d) of the 
Clean Air Act and 40 CFR part 60, subpart B that implements and enforces 
40 CFR part 60, subpart Cc. State plans include plans developed by 
States, local agencies, and protectorates.
    Tribal plan means a plan submitted by a Tribal Authority pursuant to 
40 CFR parts 9, 35, 49, 50, and 81 that implements and enforces 40 CFR 
part 60, subpart Cc.



Sec. 62.14352  Designated facilities.

    (a) The designated facility to which this subpart applies is each 
municipal solid waste landfill in all States, protectorates, and Indian 
Country that meets the conditions of paragraphs (a)(1) and (a)(2) of 
this section, except for landfills exempted by paragraphs (b) and (c) of 
this section.
    (1) The municipal solid waste landfill commenced construction, 
reconstruction, or modification before May 30, 1991 (landfills that 
commence construction, modification, or reconstruction on or after May 
30, 1991 are subject to 40 CFR part 60, subpart WWW), and
    (2) The municipal solid waste landfill has accepted waste at any 
time since November 8, 1987 or the landfill has additional capacity for 
future waste deposition.
    (b) A municipal solid waste landfill regulated by an EPA approved 
and currently effective State or Tribal plan is not subject to the 
requirements of this subpart. States that have an approved and effective 
State plan are listed in table 1 of this subpart. Notwithstanding the 
exclusions in table 1 of this subpart, any MSW landfill located in a 
State or portion of Indian country that does not have an EPA approved 
and currently effective State or Tribal plan is subject to the 
requirements of this subpart.
    (c) A municipal solid waste landfill located in a State, locality, 
or portion of Indian country that submitted a negative declaration 
letter is not subject to the requirements of this subpart other than the 
requirements in the definition of design capacity to recalculate the 
site-specific density annually and in Sec. 62.14355 to submit an amended 
design capacity report in the event that the recalculated design 
capacity is equal to or greater than 2.5 million megagrams and 2.5 
million cubic meters. However, if the existing municipal solid waste 
landfill already has a design capacity equal to or greater than 2.5 
million megagrams and 2.5 million cubic meters, then it is subject to 
the requirements of the Federal plan. States, localities, or portions of 
Indian country that submitted negative declaration letters are listed in 
table 2 of this subpart.
    (d) Physical or operational changes made to an existing municipal 
solid waste landfill solely to comply with an emission guideline are not 
considered a modification or reconstruction and would not subject an 
existing municipal solid waste landfill to the requirements of 40 CFR 
part 60, subpart WWW.
    (e) For purposes of obtaining an operating permit under title V of 
the Clean Air Act, the owner or operator of a municipal solid waste 
landfill subject to this subpart with a design capacity less than 2.5 
million megagrams or 2.5 million cubic meters is not subject to the 
requirement to obtain an operating permit for the landfill under part 70 
or 71 of this chapter, unless the landfill is otherwise subject to 
either part 70 or 71. For purposes of submitting a timely

[[Page 375]]

application for an operating permit under part 70 or 71, the owner or 
operator of a municipal solid waste landfill subject to this subpart 
with a design capacity greater than or equal to 2.5 million megagrams 
and 2.5 million cubic meters on January 7, 2,000 and not otherwise 
subject to either part 70 or 71, becomes subject to the requirements of 
Sec. 70.5(a)(1)(i) or Sec. 71.5(a)(1)(i) of this chapter April 6, 2000, 
even if the initial design capacity report is submitted earlier. In 
addition, the owner or operator of a municipal solid waste landfill 
subject to this subpart with a design capacity less than 2.5 million 
megagrams or 2.5 million cubic meters on January 7, 2000, and not 
otherwise subject to either part 70 or 71, but whose design capacity 
subsequently increases to equal or exceed 2.5 million megagrams and 2.5 
million cubic meters by a change that is not a modification or 
reconstruction becomes subject to the requirements of Sec. 70.5(a)(1)(i) 
or Sec. 71.5(a)(1)(i) of this chapter upon the date the amended design 
capacity report is due.
    (f) When a municipal solid waste landfill subject to this subpart is 
closed, the owner or operator is no longer subject to the requirement to 
maintain an operating permit under part 70 or 71 of this chapter for the 
landfill if the landfill is not otherwise subject to the requirements of 
either part 70 or 71 and if either of the following conditions are met:
    (1) The landfill was never subject to the requirement for a control 
system under Sec. 62.14353 of this subpart; or
    (2) The owner or operator meets the conditions for control system 
removal specified in 40 CFR 60.752(b)(2)(v).



Sec. 62.14353  Standards for municipal solid waste landfill emissions.

    (a) The owner or operator of a designated facility having a design 
capacity less than 2.5 million megagrams or 2.5 million cubic meters 
must comply with the requirements of 40 CFR 60.752(a) in addition to the 
applicable reporting and recordkeeping requirements specified in this

due within 90 days of the effective date of this subpart. Existing MSW 
landfills with a design capacity less than 2.5 million megagrams or 2.5 
million cubic meters that are located in States that submitted a 
negative declaration letter are not required to submit an initial design 
capacity report provided that the MSW landfill's design capacity was 
included in the negative declaration letter.
    (2) The initial nonmethane organic compounds emission rate report 
for a designated facility is due within 90 days of the effective date of 
this subpart.
    (b) The owner or operator of a designated facility must submit 
notification to the EPA Regional Office within

[[Page 376]]

10 business days of completing each increment of progress. Each 
notification must indicate which increment of progress specified in 
Sec. 62.14356(a)(1) through (a)(5) of this subpart has been achieved. 
The notification must be signed by the owner or operator of the 
landfill.
    (1) For the first increment of progress, the final control plan 
(collection and control system design plan) must be submitted in 
addition to the notification. A copy of the design plan must also be 
kept on site at the landfill.
    (2) For the second increment of progress, a signed copy of the 
contract(s) awarded must be submitted in addition to the notification.
    (c) The owner or operator of a designated facility who fails to meet 
any increment of progress specified in Sec. 62.14356(a)(1) through 
(a)(5) of this subpart according to the applicable schedule in 
Sec. 62.14356 of this subpart must submit notification that the owner or 
operator failed to meet the increment to the EPA Regional Office within 
10 business days of the applicable date in Sec. 62.14356.
    (d) The owner or operator (or the State or Tribal air pollution 
control authority) that is submitting alternative dates for increments 2 
and 3 according to Sec. 62.14356(d) of this subpart must do so by the 
date specified for submitting the final control plan. The date for 
submitting the final control plan is specified in Sec. 62.14356(c)(1) 
and (c)(2) of this subpart, as applicable. The owner or operator (or the 
State or Tribal air pollution control authority) must submit a 
justification if any of the alternative dates are later than the 
increment dates in table 3 of this subpart. In addition to submitting 
the alternative dates to the appropriate EPA Regional Office, the owner 
or operator must also submit the alternative dates to the State.



Sec. 62.14356  Compliance schedules and increments of progress.

    (a) Increments of progress. The owner or operator of a designated 
facility that has a design capacity equal to or greater than 2.5 million 
megagrams and 2.5 million cubic meters and a nonmethane organic compound 
emission rate greater than or equal to 50 megagrams per year must 
achieve the increments of progress specified in paragraphs (a)(1) 
through (a)(5) of this section to install air pollution control devices 
to meet the emission standards specified in Sec. 62.14353(b) of this 
subpart. (Refer to Sec. 62.14351 for a definition of each increment of 
progress.)
    (1) Submit control plan: Submit a final control plan (collection and 
control system design plan) according to the requirements of 
Sec. 62.14353(b) of this subpart and 40 CFR 60.752(b)(2).
    (2) Award contract(s): Award contract(s) to initiate on-site 
construction or initiate on-site installation of emission collection 
and/or control equipment.
    (3) Initiate on-site construction: Initiate on-site construction or 
initiate on-site installation of emission collection and/or control 
equipment as described in the EPA-approved final control plan.
    (4) Complete on-site construction: Complete on-site construction and 
installation of emission collection and/or control equipment.
    (5) Achieve final compliance: Complete construction in accordance 
with the design specified in the EPA-approved final control plan and 
connect the landfill gas collection system and air pollution control 
equipment such that they are fully operating. The initial performance 
test must be conducted within 180 days after the date the facility is 
required to achieve final compliance.
    (b) Compliance date. For each designated facility that has a design 
capacity equal to or greater than 2.5 million megagrams and 2.5 million 
cubic meters and a nonmethane organic compound emission rate greater 
than or equal to 50 Mg per year, planning, awarding of contracts, and 
installation of municipal solid waste landfill air emission collection 
and control equipment capable of meeting the standards in 
Sec. 62.14353(b) must be accomplished within 30 months after the date 
the initial emission rate report (or the annual emission rate report) 
first shows that the nonmethane organic compounds emission rate equals 
or exceeds 50 megagrams per year.

[[Page 377]]

    (c) Compliance schedules. The owner or operator of a designated 
facility that has a design capacity equal to or greater than 2.5 million 
megagrams and 2.5 million cubic meters and a nonmethane organic compound 
emission rate greater than or equal to 50 megagrams per year must 
achieve the increments of progress specified in paragraphs (a)(1) 
through (a)(5) of this section according to the schedule specified in 
paragraph (c)(1) or (c)(2) of this section, unless a site-specific 
schedule is approved by EPA.
    (1) The owner or operator of a designated facility must achieve the 
increments of progress according to the schedule in table 3 of this 
subpart, except for those affected facilities specified in paragraph 
(c)(2) of this section. Once this subpart becomes effective on January 
7, 2000, any designated facility to which this subpart applies will 
remain subject to the schedule in table 3 if a subsequently approved 
State or Tribal plan contains a less stringent schedule, (i.e., a 
schedule that provides more time to comply with increments 1, 4 and/or 5 
than does this Federal plan).
    (2) The owner or operator of the specified designated facility in 
table 4 of this subpart must achieve the increments of progress 
according to the schedule in table 4 of this subpart.
    (d) For designated facilities that are subject to the schedule 
requirements of paragraph (c)(1) of this section, the owner or operator 
(or the State or Tribal air pollution control authority) may submit to 
the appropriate EPA Regional Office for approval alternative dates for 
achieving increments 2 and 3.

a This table is provided as a matter of convenience and is not
  controlling in determining whether a MSW landfill is subject to the
  Federal plan. A MSW landfill is subject to this Federal plan if it
  commenced construction before May 30, 1991 and has not been modified
  or reconstructed on or after that date and is not covered by an
  approved and currently effective State or Tribal plan.
b The State plan is expected to become effective on the date indicated.
  However, if the State plan does not become effective on the date
  indicated, the Federal plan applies until the State plan becomes
