[FRL-5263-3]


Hazardous Waste Management System; Testing and Monitoring 
Activities

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA or Agency) is 
proposing to revise certain testing methods used in complying with the 
requirements of subtitle C of the Resource Conservation and Recovery 
Act (RCRA) of 1976, as amended. EPA also is proposing to add several 
new testing methods that may be used in complying with the requirements 
of subtitle C of RCRA. These new and revised methods, designated as 
Update III, are proposed to be added to the Third Edition of the EPA-
approved test methods manual ``Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods,'' EPA Publication SW-846. In addition, EPA 
proposes to delete several obsolete methods from SW-846 and the RCRA 
regulations. The intent of this action is to provide state-of-the-art 
analytical technologies for RCRA-related testing and thus promote cost 
effectiveness in choosing analytical test methods.

DATES: Comments on this proposed rule must be submitted on or before 
September 25, 1995.

ADDRESSES: The public should submit an original and two copies of their 
comments on this proposed rule to the Docket Clerk (OS-305), U.S.

I. Authority

    These regulations are being promulgated under the authority of 
sections 1006, 2002(a), 3001-3007, 3010, 3013-3018, and 7004 of the 
Solid Waste Disposal Act, as amended by the Resource Conservation and 
Recovery Act of 1976 (commonly known as RCRA), as amended (42 U.S.C. 
6905, 

[[Page 37975]]
6912(a), 6921-6927, 6930, 6934-6939, and 6974).

II. Background Summary and Regulatory Framework

    EPA Publication SW-846, ``Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods,'' contains the analytical and test methods 
that EPA has evaluated and found to be among those acceptable for 
testing under subtitle C of the Resource Conservation and Recovery Act 
(RCRA) and that are required for specific regulations as discussed 
below. These methods are intended to promote accuracy, sensitivity, 
specificity, precision, and comparability of analyses and test results. 
In situations where the regulations require the use of appropriate SW-
846 methods, the regulations specify use of the Third Edition of EPA's 
SW-846 manual as amended by Updates I, II, IIA, and IIB. SW-846 will be 
amended further to include the new and revised methods contained in 
this proposed Update III, and to delete those methods deemed obsolete 
in this proposal, if this proposal is adopted in final form.
    Several of the hazardous waste regulations under subtitle C of RCRA 
require that specific testing methods described in SW-846 be employed 
for certain applications. Any reliable analytical method may be used to 
meet other requirements in 40 CFR parts 260 through 270. Listed below 
are a number of provisions found in 40 CFR parts 260 through 270 that 
require use of a specific method for a particular application, or the 
use of appropriate SW-846 methods in general:
    (1) Section 260.22(d)(1)(i)--Submission of data in support of 
petitions to exclude a waste produced at a particular facility (i.e., 
delisting petitions);
    (2) Section 261.22(a)(1) and (2)--Evaluation of a waste against the 
corrosivity characteristic;
    (3) Section 261.24(a)--Leaching procedure for evaluation of a waste 
against the toxicity characteristic;
    (4) Section 261.35(b)(2)(iii)(A)--Testing rinsates from wood 
preserving cleaning processes;
    (5) Sections 264.190(a), 264.314(c), 265.190(a), and 265.314(d)--
Evaluation of a waste to determine if free liquid is a component of the 
waste;
    (6) 264.1034(d)(1)(iii) and 265.1034(d)(1)(iii)--Testing total 
organic concentration for monitoring compliance with air emission 
standards for process vents;
    (7) 264.1063(d)(2) and 265.1063(d)(2)--Testing total organic 
concentration for monitoring compliance with air emission standards for 
equipment leaks;
    (8) Section 266.106(a)--Analysis in support of compliance with 
standards to control metals emissions from burning hazardous waste in 
boilers and industrial furnaces;
    (9) Section 266.112(b)(1) and (2)(i)--Certain analyses in support 
of exclusion from the definition of a hazardous waste of a residue 
which was derived from burning hazardous waste in boilers and 
industrial furnaces;
    (10) Section 268.32(i)--Evaluation of a waste to determine if it is 
a liquid for purposes of certain land disposal prohibitions;
    (11) Sections 268.40(a), (b) and (f), 268.41(a), and 268.43(a)--
Leaching procedure for evaluation of waste extract to determine 
compliance with land disposal treatment standards;
    (12) Section 268.7(a)--Leaching procedure for evaluation of a waste 
to determine if the waste is restricted from land disposal;
    (13) Sections 270.19(c)(1)(iii) and (iv), and 270.62(b)(2)(i)(C) 
and (D)--Analysis and approximate quantification of the hazardous 
constituents identified in the waste prior to conducting a trial burn 
in support of an application for a hazardous waste incineration permit; 
and
    (14) Sections 270.22(a)(2)(ii)(B) and 270.66(c)(2)(i) and (ii)--
Analysis conducted in support of a destruction and removal efficiency 
(DRE) trial burn waiver for boilers and industrial furnaces burning 
low-risk wastes, and analysis and approximate quantification conducted 
for a trial burn in support of an application for a permit to burn 
hazardous waste in a boiler and industrial furnace.
    In other situations, SW-846 functions as a guidance document 
setting forth acceptable, although not required, methods to be 
implemented by the user, as appropriate, in responding to RCRA-related 
sampling and analysis requirements.
    SW-846 is a document that changes over time as new information and 
data are developed. Advances in analytical instrumentation and 
techniques are continually reviewed by the Agency and periodically 
incorporated into SW-846 to support changes in the regulatory program 
and to improve method performance. Update III represents such an 
incorporation. Therefore, EPA solicits any available data and 
information that may affect the usefulness of SW-846.

III. Proposal

A. Revised Methods and Chapters

    The Agency is today proposing to revise several methods contained 
in the Third Edition 1 of SW-846 and its Updates I, II, IIA, and 
IIB, as incorporated by reference into 40 CFR 260.11(a). These proposed 
revisions would improve the methods and provide additional performance 
information for each method. The Agency is also proposing to revise SW-
846 Chapters Two, Three, Four, Five, Six, and Ten to incorporate new 
methods and method revisions into SW-846.

    \1\ For an exception, see footnote number 1 of Table 1.
---------------------------------------------------------------------------

    Table 1 lists the 37 methods and the six chapters that are proposed 
for revision. The revised methods and chapters are available from the 
Government Printing Office (GPO) and the National Technical Information 
Service (NTIS), and are part of the official docket for this 
rulemaking. For comparison purposes, original versions of the methods 
and chapters before these revisions can be found in Docket Nos. F-93-
WTMF-FFFFF (Third Edition and Update I) and F-94-WT2F-FFFFF (Update 
II). The revised methods of proposed Update III can be found in Docket 
No. F-95-WT3P-FFFFF. Those with SW-846 subscriptions can refer to their 
copies of the Third Edition of SW-846 as amended by Updates I, II, IIA, 
and IIB; and to their copy of proposed Update III. The Agency is 
soliciting comments on all parts of each revised method, with the 
exception of Method 9095A for the reasons explained in section III.D of 
this proposed rule.
    In its ongoing program to promote pollution prevention, the Agency 
notes that eighteen (see method numbers identified by an asterisk in 
Table 1) of the organic sample preparatory and cleanup methods which 
are proposed to be revised in Update III of SW-846 utilize a modified 
Kuderna-Danish (K-D) apparatus to concentrate sample extracts and 
minimize the evaporation of extraction solvents into the air. 
Specifically, the modified K-D apparatus in these methods includes a 
solvent recovery system. The recovered solvent can be properly disposed 
instead of released to the air as previously done. (Note: The K-D 
apparatus found in new Methods 3535 and 3542 of proposed Update III 
also include this pollution prevention improvement.)

[[Page 37976]]


B. New Methods

    The Agency is today proposing to add 61 new methods to the Third 
Edition of SW-846 (Table 2). If finalized, these new methods will 
provide additional flexibility in method selection and also may be used 
during the analyses of some analytes for which other SW-846 methods may 
be less than adequate performers. These new methods are available from 
GPO and NTIS, and are part of the official docket for this rulemaking. 
The Agency is soliciting comments on all sections of these methods.
    EPA's Office of Solid Waste is also considering adopting the 
Environmental Monitoring Management Council (EMMC) format for use with 
new SW-846 methods in a future proposed revision (other than Update 
III) to SW-846. As part of its efforts to promote consolidation and 
integration between EPA Program Offices, the EMMC developed the 
consensus format for analytical methods. The Agency plans to consider 
adopting this format to be consistent with an intra-agency effort to 
achieve uniformity in analytical method format among all Agency 
programs. The use of this new format for new methods of SW-846 will be 
proposed per comment in a future rulemaking. The Agency is not 
soliciting comment at this time on its plans to adopt the EMMC format.

C. Deletion of Obsolete Methods

    The Agency is also proposing today to delete sixteen obsolete 
methods (Table 3) from the Third Edition of SW-846, for the reasons 
delineated in the following paragraphs. The Agency is soliciting 
comments on the removal of the methods from SW-846.
    Fourteen packed column gas chromatographic (GC) methods are 
proposed for deletion from SW-846 because they have been superseded by 
capillary column methods or other method techniques that provide better 
resolution, selectivity and sensitivity. Capillary columns have an 
inherently greater ability to separate analytes than packed columns. A 
survey performed in 1991 found that few analysts actually use packed 
columns in their laboratories anymore (Environmental Science and 
Technology, 26, 1285-1287, 1992). These packed column GC methods are 
also proposed for deletion to be consistent with other Agency program 
offices, e.g., the Office of Water, which has withdrawn packed column 
methods from its list of approved drinking water methods (see 59 FR 
62456, December 5, 1994).
    Method 9200, the brucine-sulfanilamide method for nitrate 
determination, is proposed for deletion because it generates unreliable 
results. It was recently demonstrated to be unreliable by both the 
Agency's Environmental Monitoring Systems Laboratory in Cincinnati 
(EMSL-Ci) and the American Water Works Association (AWWA). The unstable 
nature of the analytical reagents and excessively tight temperature 
control requirements were among the factors contributing to the 
method's unreliability. In fact, on December 15, 1993 (58 FR 65622), 
the Agency proposed to remove Method 353.1 (EPA 600/4-79-020, ``Methods 
for the Chemical Analysis of Water and Wastes'') which contains a 
brucine-sulfanilic acid procedure. Method 419 D, a brucine-sulfanilic 
acid method, was also removed by the American Water Works Association 
from the publication ``Standard Methods for the Examination of Water 
and Wastewater'', Fifteenth Edition. Therefore, to be consistent with 
these and any other related Agency actions, the Agency is proposing to 
remove Method 9200 from SW-846. In the rare cases where nitrate is a 
target analyte for RCRA-related analyses, the regulated community may 
use Method 9056--The Determination of Inorganic Anions by Ion 
Chromatography (currently in SW-846). Another appropriate method may be 
Method 9210--Nitrate in Aqueous Samples by Ion-Selective Electrode, 
which is a proposed Update III method and listed in Table 2 of this 
notice. Alternative methods are also available from other sources, 
including, but not limited to, the ``Annual Book of ASTM Methods'' 
(American Society for Testing and Materials, Philadelphia, PA); 
``Standard Methods for the Examination of Water and Wastewater'' 
(Eighteenth Edition, 1992, American Public Health Association, the 
American Water Works Association, and the Water Environment Federation, 
Washington, DC); and the Office of Water methods manual ``Methods for 
the Chemical Analysis of Water and Wastes'' (EPA, March 1983, NTIS 
PB84-128677)
    Method 9252A--Chloride (Titrimetric, Mercuric Nitrate) is proposed 
to be deleted from SW-846 as part of the Agency's ongoing efforts to 
promote pollution prevention measures. Although the method does give 
reliable results, it can generate a mercury-containing RCRA hazardous 
waste, which may cause disposal or contamination problems for the 
laboratory. Several alternative methods for the determination of 
chloride are available both in SW-846 (e.g., Methods 9250, 9251 and 
9253) and from other sources including, but not limited to, the 
``Annual Book of ASTM Methods'' (American Society for Testing and 
Materials, Philadelphia, PA), ``Standard Methods for the Examination of 
Water and Wastewater'' (Eighteenth Edition, 1992, American Public 
Health Association, the American Water Works Association, and the Water 
Environment Federation, Washington, DC), and the Office of Water 
methods manual, ``Methods for the Chemical Analysis of Water and 
Wastes'' (EPA, March 1983, NTIS PB84-128677).

D. Request for Comment Only on Certain Sections of Method 9095A

    Revised Method 9095A (``Paint Filter Liquids Test'') contains 
revisions to sections 6.2, 7.2, 7.3 and 7.4 that provide direction on 
how to prepare sorbent materials that do not conform to the shape of 
the paint filter. This direction is intended to facilitate use of the 
method for the testing of containerized liquids to which sorbents have 
been added before land disposal. The Agency adopted Method 9095A for 
this purpose on November 18, 1992 (see 57 FR 54452, the ``Liquids in 
Landfills'' rule). Method 9095A also contains a new section 3.2 which 
clarifies use of the method during freezing conditions. The Agency is 
requesting comment only on the sections of Method 9095A listed above, 
is not requesting comment on other sections of the method (which were 
not revised), and is also not requesting comment on method 
appropriateness for free liquid determinations.

E. Deleting References to Method 8240 in Secs. 264.1034(d)(iii) and 
(f), 264.1063(d)(2), 265.1034(d)(1)(iii) and (f), and 265.1063(d)(2)

    The Agency is proposing to delete all references to Method 8240 
(Volatile Organic Compounds by Gas Chromatography/Mass Spectrometry) of 
SW-846 found in 40 CFR 264.1034(d)(1)(iii) and (f), 264.1063(d)(2), 
265.1034(d)(1)(iii) and (f), and 265.1063(d)(2) of the RCRA 
regulations. The Agency is proposing this action because a method 
involving the determination of volatile organic compounds (e.g., Method 
8240 or 8260) is not an appropriate method alternative for the total 
organic carbon analysis addressed by 40 CFR 264.1034(d)(1)(iii) and 
(f), 264.1063(d)(2), 265.1034(d)(1)(iii) and (f), and 265.1063(d)(2), 
since it exhibits no direct correlation with analytical results 
obtained using Method 9060. In addition, Method 8240 is a packed column 
method and, for the reasons 

[[Page 37977]]
explained in section III.C of this proposal, the Agency is removing 
Method 8240 (and all other packed column methods) from SW-846.

\1\ Method 3060, ``Alkaline Digestion for Hexavalent Chromium,'' was in 
  the Second Edition of SW-846, but was not included in SW-846, Third   
  Edition, due to perceived poor performance. The method has since been 
  extensively studied, modified, and validated, and Method 3060A is now 
  being proposed for inclusion as a revised method to SW-846.

IV. State Authority

    Today's rule, if promulgated, will provide standards that are not 
immediately effective in authorized States since the requirements are 
being imposed pursuant to pre-HSWA authority. See RCRA section 3006. 
The requirements will be applicable only in those States that do not 
have interim or final authorization. In authorized States, the 
requirements will not be applicable until the State revises its program 
to adopt equivalent requirements under State law. Procedures and 
deadlines for State program revisions are set forth in 40 CFR 271.21. 
40 CFR 271.3 sets forth the requirements a State must meet when 
submitting its final authorization application.

V. Regulatory Analyses

A. Executive Order 12866

    Under Executive Order 12866 (58 FR 51735 (October 4, 1993)), EPA 
must determine whether a regulatory action is ``significant'' and 
therefore subject to OMB review and the requirements of the Executive 
Order. The Order defines ``significant regulatory action'' as one that 
is likely to result in a rule that may:
    (1) Have an annual effect on the economy of $100 million or more or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or tribal governments or 
communities;
    (2) Create a serious inconsistency or otherwise interfere with an 
action taken or planned by another agency;
    (3) Materially alter the budgetary impact of entitlements, grants, 
user fees, or loan programs or the rights and obligations of recipients 
thereof; or 

[[Page 37979]]

    (4) Raise novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
the Executive Order.
    The Agency has determined that this rule is not a ``significant 
regulatory action'' under the terms of Executive Order 12866 and is 
therefore not subject to OMB review and the requirements of the 
Executive Order.

B. Unfunded Mandates Reform Act

    Under section 202 of the Unfunded Mandates Reform Act of 1995 (the 
Act), Pub. L. 104-4, which was signed into law on March 22, 1995, EPA 
generally must prepare a written statement for rules with Federal 
mandates that may result in estimated costs to State, local, and tribal 
governments in the aggregate, or to the private sector, of $100 million 
or more in any one year. When such a statement is required for EPA 
rules, under section 205 of the Act EPA must identify and consider 
alternatives, including the least costly, most cost-effective or least 
burdensome alternative that achieves the objectives of the rule. EPA 
must select that alternative, unless the Administrator explains in the 
final rule why it was not selected or it is inconsistent with law. 
Before EPA establishes regulatory requirements that may significantly 
or uniquely affect small governments, including tribal governments, it 
must develop under section 203 of the Act a small government agency 
plan. The plan must provide for notifying potentially affected small 
governments, giving them meaningful and timely input in the development 
of EPA regulatory proposals with significant Federal intergovernmental 
mandates, and informing, educating, and advising them on compliance 
with the regulatory requirements.
    EPA has determined that this rule does not include a Federal 
mandate that may result in estimated costs of $100 million or more to 
State, local, and tribal governments in the aggregate, or to the 
private sector, in any one year. This is due to the fact that this rule 
simply revises available test methods for complying with existing 
regulatory requirements, and in most cases, the SW-846 test methods are 
provided as guidance, not requirements. Even where the use of a 
specific test method is required, the Agency does not believe that the 
revised methods will result in significant cost increases and indeed, 
most of the revised methods are expected to result in reduced costs. 
For example, new immunoassay methods can be run in the field, replacing 
expensive gas chromatographic laboratory work; this will allow for more 
and faster sampling, helping to reduce the cost of cleanups. Thus, 
today's notice is not subject to the written statement requirements in 
sections 202 and 205 of the Act.
    As for section 203 of the Act, today's rule is not expected to have 
any ``unique'' effects on small governments; the only expected effects 
on a small government would be where that government is itself managing 
hazardous wastes, and is using one or more test methods for complying 
with RCRA regulations. Further, for the reasons set out in the prior 
paragraph, the revised test methods would not be expected to have a 
``significant'' effect on small governments (or other users of test 
methods). Thus, today's notice is not subject to the requirements of 
section 203 of the Act.
C. Regulatory Flexibility Act

    Pursuant to the Regulatory Flexibility Act (RFA) (5 U.S.C. section 
601-612, Pub. L. 96-354, September 19, 1980), whenever an agency 
publishes a General Notice of Rulemaking for any proposed or final 
rule, it must prepare and make available for public comment a 
regulatory flexibility analysis (RFA) that describes the impact of the 
rule on small entities (i.e., small businesses, small organizations, 
and small governmental jurisdictions). No regulatory flexibility 
analysis is required, however, if the head of the Agency certifies that 
the rule will not have a significant impact on a substantial number of 
small entities.
    This rule will not require the purchase of new instruments or 
equipment. The regulation requires no new reports beyond those now 
required. This rule will not have an adverse economic impact on small 
entities since its effect will be to provide greater flexibility and 
utility to all of the regulated community, including small entities, by 
providing an increased choice of appropriate analytical methods for 
RCRA applications. Therefore, in accordance with 5 U.S.C. section 
605(b), I hereby certify that this rule will not have a significant 
economic impact on a substantial number of small entities. Thus, the 
regulation does not require an RFA.

D. Paperwork Reduction Act

    There are no additional reporting, notification, or recordkeeping 
provisions associated with today's proposed rule. Such provisions, were 
they included, would be submitted for approval to the Office of 
Management and Budget (OMB) under the Paperwork Reduction Act, 44 
U.S.C. 3501 et seq.
