Alternate PCB Extraction Methods and Amendments to PCB Cleanup 
and Disposal Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA or the Agency) is 
finalizing an expanded set of extraction and determinative methods that 
can be used to characterize and verify the cleanup of polychlorinated 
biphenyls (PCBs) waste under implementing regulations for PCB-related 
authority in the Federal Toxic Substances Control Act (TSCA) (also 
referred to as the PCB regulations). These changes are expected to 
greatly reduce the amount of solvent used in PCB extraction processes, 
thereby conserving resources and reducing waste. In addition, the 
changes are expected to result in quicker, more efficient, and less 
costly cleanups, due to greater flexibility in the cleanup and disposal 
of PCB waste, while still being equally protective of human health and 
the environment. EPA is also finalizing several other amendments to the 
PCB regulations, including the amendment of the performance-based 
disposal option for PCB remediation waste; the removal of the provision 
allowing PCB bulk product waste to be disposed of as roadbed material; 
the addition of more flexible provisions for cleanup and disposal of 
waste generated by spills that occur during emergency situations (e.g., 
hurricanes or floods); harmonization of the general disposal 
requirements for PCB remediation waste; and other amendments to improve 
the implementation of the regulations, clarify ambiguity, and correct 
technical errors.

DATES: This rule is effective February 26, 2024. The incorporation by 
reference of certain material listed in the rule is approved by the 
Director of the Federal Register as of February 26, 2024. The 
incorporation by reference of certain other material listed in the rule 
was approved by the Director of the Federal Register as of January 18, 
2012.

rulemaking, including a summary of the comments received and how the 
proposed changes are being finalized in this rule, please see Section 
III. Discussion of the Public Comments and Final Rule. Comments that 
warranted changes or preamble clarification are discussed in this 
rulemaking; for a complete response to comments, see ``Response to 
Comments on the Proposed PCB Rulemaking'' in the docket.
    This final rule addresses several key issues related to 
implementing the PCB Cleanup and Disposal Program under TSCA, 
including:
Revise Available Extraction Methods for PCBs
    EPA is adding the following extraction methods from SW-846, Test 
Methods for Evaluating Solid Waste, to the PCB regulations in 40 CFR 
part 761 for use on solid matrices: Method 3541 (Automated Soxhlet 
Extraction), Method 3545A (Pressurized Fluid Extraction), and Method 
3546 (Microwave Extraction). EPA is also adding the following 
extraction methods from SW-846, Test Methods for Evaluating Solid 
Waste, to the PCB regulations in 40 CFR part 761 for use on aqueous 
matrices: Method 3510C (Separatory Funnel Liquid-Liquid Extraction), 
Method 3520C (Continuous Liquid-Liquid Extraction), and Method 3535A 
(Solid-Phase Extraction). The Agency is also incorporating by reference 
Methods 3541, 3545A, 3546, 3510C, 3520C, and 3535A into Sec.  761.19.
Update and Limit the Use of Ultrasonic Extraction
    EPA is revising the PCB regulations in 40 CFR part 761 to update 
SW-846 Method 3550B (Ultrasonic Extraction) to the newer method 3550C 
(Ultrasonic Extraction) and to limit the use of Method 3550C to wipe 
samples only.
Revise Available Determinative Methods for PCBs
    EPA is adding the determinative method SW-846 Method 8082A 
(Polychlorinated Biphenyls (PCBs) By Gas Chromatography) to the PCB 
regulations in 40 CFR part 761. EPA is also updating the inclusion of 
Clean Water Act (CWA) Method 608 (Organochlorine Pesticides and PCBs) 
to the newer version, Method 608.3 (Organochlorine Pesticides and PCBs 
by GC/HSD).
Revise Performance-Based Disposal Under Sec.  761.61(b)
    EPA is amending the performance-based disposal option for PCB 
remediation waste under Sec.  761.61(b) to include provisions for 
performance-based cleanup such as applicability, cleanup levels, 
verification sampling, and recordkeeping and notification requirements. 
EPA is also adding RCRA Subtitle C permitted landfills to the list of 
allowed performance-based disposal options for non-liquid PCB 
remediation waste.
Remove Regulatory Provision Allowing Disposal of PCB Bulk Product Waste 
as Roadbed
    EPA is removing the option in Sec.  761.62(d)(2) that allows for 
disposal of PCB bulk product waste under asphalt as part of a roadbed.
Add Flexible Provisions for Emergency Situations
    EPA is adding new provisions for emergency situations under Sec.  
761.66 to allow individuals to request a waiver from specific 
requirements of Sec. Sec.  761.60, 761.61, 761.62, and 761.65, when 
necessitated by an emergency situation. EPA is also adding two 
provisions to the existing PCB Spill Cleanup Policy in 40 CFR part 761, 
subpart G, that allow for more flexible requirements for cleanup of 
spills caused by and managed during emergency situations, such as 
hurricane or floods.
Harmonize General Disposal Requirements for PCB Remediation Waste
    EPA is amending Sec.  761.50(b)(3)(ii) to remove a phrase that was 
added erroneously in 1998, which could imply that waste with <50 parts 
per million (ppm) PCBs that meets the definition of PCB remediation 
waste in Sec.  761.3 is not regulated for cleanup and/or disposal.
Make Changes To Improve Regulatory Implementation
    EPA is making several supplemental amendments to improve 
implementation of existing requirements, clarify regulatory ambiguity, 
and correct technical errors in the PCB regulations.

II. Background

A. General Background on Polychlorinated Biphenyls (PCBs) and This 
Rulemaking

What are PCBs?
    PCBs are a group of man-made organic chemicals known as chlorinated 
hydrocarbons, which consist of carbon, hydrogen, and chlorine atoms. 
PCBs were manufactured in the United States from 1929 until 
manufacturing was banned in 1979, with certain time-limited exemptions 
from the statutory prohibition that were granted by rule. Note that the 
PCB regulations also provide for excluded manufacturing processes, as 
defined in 40 CFR 761.3, which include inadvertent generation. The 
number of chlorine atoms and their location in a PCB molecule determine 
many of its physical and chemical

[[Page 59664]]

properties. PCBs have no known taste or smell, and range in consistency 
from thin, light-colored liquids to yellow or black waxy solids. Due to 
their non-flammability, chemical stability, high boiling point and 
electrical insulating properties, PCBs were previously used in hundreds 
of industrial and commercial applications including: electrical, heat 
transfer and hydraulic equipment; plasticizers in paints, plastics and 
rubber products; pigments, dyes and carbonless copy paper; and other 
industrial applications. The PCBs used in these products were chemical 
mixtures made up of a variety of individual chlorinated biphenyl 
components known as congeners. Most commercial PCB mixtures are known 
in the United States by their industrial trade names, the most common 
being Aroclor. Please visit https://www.epa.gov/pcbs/learn-about-polychlorinated-biphenyls-pcbs for more information.

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

    PCBs are persistent in the environment and can cause both acute and 
chronic health effects. Short-term exposure to high concentrations of 
PCBs can lead to skin conditions such as acne and rashes and may be 
associated with decreased liver function, neurological effects, and 
gastrointestinal effects. These high levels of exposure are generally 
rare in the general population. Chronic exposure to lower 
concentrations of PCBs may also cause health effects, as PCBs can 
accumulate in people over time. In animal studies, PCBs have been shown 
to cause effects on the immune, reproductive, nervous, hepatic, and 
endocrine systems. PCBs have also been shown to cause cancer in 
animals. Some studies in humans provide supportive evidence for some of 
these health effects. Studies also show that PCBs in pregnant women can 
affect their children's birth weight, short-term memory, and learning. 
Also, because of potential neurotoxic and endocrine effects, there is 
concern regarding children's exposures to PCBs.
    PCBs are highly persistent in the environment. As such, they are 
still present in soils and sediments at many locations and may be found 
at low levels in ambient air and water, even decades after their 
production was banned. PCBs can be released into the environment from 
hazardous waste sites, illegal or improper disposal of industrial 
wastes and consumer products, leaks from old electrical transformers 
and capacitors containing PCBs and burning of some wastes in 
incinerators, among other sources. PCBs bioaccumulate and may be 
present in foods that people consume, such as fish, meat, and dairy 
products. Dietary consumption of contaminated foods is believed to be 
an important route of background exposure.
Laws and Regulations
    This final rule is issued pursuant to section 6(e) of the Toxic 
Substances Control Act, 15 U.S.C. 2605(e). Section 6(e)(1)(A) gives EPA 
the authority to promulgate rules regarding the disposal of PCBs (15 
U.S.C. 2605(e)(1)(A)). TSCA section 6(e)(2) and (e)(3) generally 
prohibit the manufacture, processing, distribution in commerce, and use 
(other than totally enclosed use) of PCBs (15 U.S.C. 2605(e)(2) and 
(e)(3)). TSCA section 6(e)(2)(B) gives EPA the authority to authorize 
the use of PCBs in other than a totally enclosed manner based on a 
finding of no unreasonable risk of injury to health or the environment 
(15 U.S.C. 2605(e)(2)(B)). TSCA section 6(e)(3)(B) provides that any 
person may petition EPA for an exemption from the prohibition on the 
manufacture, processing, and distribution in commerce of PCBs (15 
U.S.C. 2605(e)(3)(B)). EPA may grant an exemption based on findings 
that an unreasonable risk of injury to health or the environment will 
not result, and that the petitioner has made good faith efforts to 
develop a substitute for PCBs.
    The PCB regulations can be found in Title 40 of the Code of Federal 
Regulations (CFR) in Part 761. For useful interpretations of the 
regulations as well as answers to frequently asked questions, please

B. Assumptions and Terminology Used in Discussion of Various Methods

Sources of the Methods
    There are two important sources of EPA methods related to this 
rulemaking. The first source is SW-846, also known as The Test Methods 
for Evaluating Solid Waste: Physical/Chemical Methods Compendium, which 
is EPA's collection of methods for use in complying with the Resource 
Conservation and Recovery Act (RCRA). SW-846 is organized into chapters 
providing guidance on how to use the methods and groups of methods, 
called ``series,'' which are organized by topic. The methods change 
over time as updates are published to keep up with evolving analytical 
and measurement needs.\4\ The second source is the Clean Water Act 
(CWA) Methods, which are laboratory analytical methods, or test 
procedures, published by EPA that are used by industries and 
municipalities to analyze the chemical, physical, and biological 
components of wastewater and other environmental samples.\5\ Methods 
for both SW-846 and CWA go through an extensive review and validation 
process before they are published and made available.

Technical Summary of New Methods
    EPA Method 3540C--This Method is a procedure for extracting 
nonvolatile and semivolatile organic compounds from solids such as 
soils, sludges, and wastes. The Soxhlet extraction process ensures 
intimate contact of the sample matrix with the extraction solvent. This 
method is applicable to the isolation and concentration of water-
insoluble and slightly water-soluble organics in preparation for a 
variety of chromatographic procedures. The solid sample is mixed with 
anhydrous sodium sulfate, placed in an extraction thimble or between 
two plugs of glass wool, and extracted using an appropriate solvent in 
a Soxhlet extractor. The extract is then dried, concentrated (if 
necessary), and, as necessary, exchanged into a solvent compatible with 
the cleanup or determinative step being employed.
    EPA Method 3550C--This method describes a procedure for extracting 
nonvolatile and semivolatile organic compounds from solids such as 
soils, sludges, and wastes. The ultrasonic process ensures intimate 
contact of the sample matrix with the extraction solvent. This method 
is divided into two procedures, based on the expected concentration of 
organic compounds. Low concentration procedure--The sample is mixed 
with anhydrous sodium sulfate to form a free-flowing powder. The 
mixture is extracted with solvent three times, using ultrasonic 
extraction. The extract is separated from the sample by vacuum 
filtration or centrifugation. The extract is ready for final 
concentration, cleanup, and/or

[[Page 59665]]

analysis. Medium/high concentration procedure--The sample is mixed with 
anhydrous sodium sulfate to form a free-flowing powder. This is 
extracted with solvent once, using ultrasonic extraction. A portion of 
the extract is collected for cleanup and/or analysis.
    EPA Method 8082A--This method may be used to determine the 
concentrations of polychlorinated biphenyls (PCBs) as Aroclors or as 
individual PCB congeners in extracts from solid, tissue, and aqueous 
matrices, using open-tubular, capillary columns with electron capture 
detectors (ECD) or electrolytic conductivity detectors (ELCD). The 
method also may be applied to other matrices such as oils and wipe 
samples, if appropriate sample extraction procedures are employed.
    EPA Method 3546: Microwave Extraction--This method is known for its 
relatively brief extraction time and low equipment costs. In a 
microwave extraction, a sample is prepared for extraction by grinding 
it to a powder and then loading it into the extraction vessel. The 
appropriate solvent system is added to the vessel, which is then 
sealed. The extraction vessel containing the sample and solvent system 
is then heated to the extraction temperature and is extracted for the 
amount of time recommended by the instrument manufacturer. After the 
mixture cools, the vessel is opened and the contents are filtered. The 
solid material is then rinsed multiple times, and the various solvent 
fractions are combined. Finally, the extract may be concentrated, if 
necessary, and, as needed, exchanged into a solvent compatible with the 
cleanup or determinative procedure to be employed.
    EPA Method 3545A: Pressurized Fluid Extraction (PFE)--When 
performing a pressurized fluid extraction, a sample is prepared for 
extraction either by air drying the sample, or by mixing the sample 
with anhydrous sodium sulfate or pelletized diatomaceous earth. The 
sample is then ground and loaded into an extraction cell. The 
extraction cell containing the ground sample is then heated to the 
extraction temperature, pressurized with the appropriate solvent 
system, and extracted for the period of time recommended by the 
instrument manufacturer. The solvent is then collected from the heated 
extraction vessel and allowed to cool. Finally, the extract may be 
concentrated, if necessary, and, as needed, exchanged into a solvent 
compatible with the cleanup or determinative step being employed.
    EPA Method 3541: Automated Soxhlet Extraction--This method shares 
many similarities with Manual Soxhlet Extraction (EPA Method 3540C); 
however, it takes less time and solvent per sample. When performing an 
Automated Soxhlet Extraction, a moist solid sample (e.g., soil/sediment 
samples) may be air-dried and ground prior to extraction or chemically 
dried with anhydrous sodium sulfate. The prepared sample is then 
extracted using 1:1 acetone:hexane in the automated Soxhlet system.
    EPA Method 3510C: Separatory Funnel Liquid-Liquid Extraction--This 
method describes a procedure for isolating organic compounds from 
aqueous samples. The method also describes concentration techniques 
suitable for preparing the extract for the appropriate determinative 
methods. A measured volume of sample, usually 1 liter, at a specified 
pH, is serially extracted with methylene chloride using a separatory 
funnel. The extract is dried, concentrated (if necessary), and, as 
necessary, exchanged into a solvent compatible with the cleanup or 
determinative method to be used.
    EPA Method 3520C: Continuous Liquid-Liquid Extraction--This method 
describes a procedure for isolating organic compounds from aqueous 
samples. The method also describes concentration techniques suitable 
for preparing the extract for the appropriate determinative steps. 
Method 3520 is designed for extraction solvents with greater density 
than the sample. A measured volume of sample, usually 1 liter, is 
placed into a continuous liquid-liquid extractor, adjusted, if 
necessary, to a specific pH, and extracted with organic solvent for 18-
24 hours. The extract is dried, concentrated (if necessary), and, as 
necessary, exchanged into a solvent compatible with the cleanup or 
determinative method being employed.
    EPA Method 3535A: Solid-Phase Extraction (SPE)--This is a procedure 
for isolating target organic analytes from aqueous samples using solid-
phase extraction (SPE) media. It describes conditions for extracting a 
variety of organic compounds from aqueous matrices that include 
groundwater, wastewater, and Toxicity Characteristic Leaching Procedure 
(TCLP) leachates. The extraction procedures are specific to the 
analytes of interest and vary by group of analytes and type of 
extraction media.
    ASTM D482-13--This test method covers the determination of ash in 
the range 0.010% to 0.180% by mass, from distillate and residual fuels, 
gas turbine fuels, crude oils, lubricating oils, waxes, and other 
petroleum products, in which any ash-forming materials present are 
normally considered to be undesirable impurities or contaminants (Note 
1). The test method is limited to petroleum products which are free 
from added ash-forming additives, including certain phosphorus 
compounds
    ASTM D5373-16--Test Method A covers the determination of carbon in 
the range of 54.9% to 84.7%, hydrogen in the range of 3.25% to 5.10%, 
and nitrogen in the range of 0.57% to 1.80% in the analysis samples 
(8.1) of coal and of carbon in analysis samples of coke in the range of 
86.6% to 97.9%. Test Method B covers the determination of carbon in 
analysis samples of coal in the range of 58.0% to 84.2%, and carbon in 
analysis samples of coke in the range of 86.3% to 95.2%.
    ASTM D3278-96(R2011)--These test methods cover procedures for 
determining whether a material does or does not flash at a specified 
temperature or for determining the lowest finite temperature at which a 
material does flash when using a small scale closed-cup apparatus.2 The 
test methods are applicable to paints, enamels, lacquers, varnishes, 
and related products having a flash point between 0 and 110 [deg]C (32 
and 230 [deg]F) and viscosity lower than 150 St at 25 [deg]C (77 
[deg]F).
    ASTM E258-67(R87)--This test method covers the determination of 
total nitrogen in nitrogen-containing organic compounds. This test 
method is not applicable for use on materials containing N-O, N-N 
linkages.
    ASTM D4059-00--This test method describes a quantitative 
determination of the concentration of polychlorinated biphenyls (PCBs) 
in electrical insulating liquids by gas chromatography. It also applies 
to the determination of PCB present in mixtures known as askarels, used 
as electrical insulating liquids.
    ASTM D8174-18--This test method covers the procedure for a flash 
point test, within the range of -20 to 70 [deg]C, of liquid wastes 
using a small-scale closed cup tester. This standard measures the 
ignitability properties of liquid wastes (which may be any discarded 
material), which may include secondary materials, off-specification 
products, and materials containing free liquids recovered during 
emergency response actions.
    ASTM D8175-18--This test method covers the procedure for a finite 
flash point test, within the range of 20 to 70 [deg]C, of liquid wastes 
using a manual or automated Pensky-Martens closed cup tester. This test 
method contains two procedures and is applicable to liquid waste, 
liquid phase(s) of multi-phase waste, liquid waste with suspended 
solids, or liquid waste that tends to form a surface film under test 
conditions.

Terminology of the Methods
    To avoid confusion with the variety of methods discussed, the 
source of each method, and the numbering of the methods, EPA is using 
streamlined terminology in this preamble to improve its readability. 
For example, rather than stating ``SW-846, Test Methods for Evaluating 
Solid Waste, EPA Method 3540C (Soxhlet Extraction)'' each time this 
method is discussed, the preamble may refer to ``Method 3540C'' or 
``Method 3540C (Soxhlet Extraction)'' instead. See Table 1 for a list

III. Discussion of Public Comments and the Final Rule

A. Revise Available Extraction Methods for PCBs

Provisions in the Final Rule
    EPA proposed to add the following extraction methods to 40 CFR part 
761: Method 3541 (Automated Soxhlet Extraction), Method 3545A 
(Pressurized Fluid Extraction), and Method 3546 (Microwave Extraction) 
for extraction of PCBs from solid matrices; and Method 3510C 
(Separatory Funnel Liquid-Liquid Extraction), Method 3520C (Continuous 
Liquid-Liquid Extraction), and Method 3535A (Solid-Phase Extraction) 
for extraction of PCBs from aqueous matrices. EPA is finalizing these 
changes as proposed. EPA is allowing these methods for use, as 
applicable, under the following subparts of 40 CFR part 761:
     Subpart D--Storage and Disposal;
     Subpart K--PCB Waste Disposal Records and Reports;
     Subpart M--Determining a PCB Concentration for Purposes of 
Abandonment or Disposal of Natural Gas Pipeline: Selecting Sites, 
Collecting Surface Samples, and Analyzing Standard PCB Wipe Samples;
     Subpart N--Cleanup Site Characterization Sampling for PCB 
Remediation Waste in Accordance with Sec.  761.61(a)(2);
     Subpart O--Sampling to Verify Completion of Self-
Implementing Cleanup and On-Site Disposal of Bulk PCB Remediation Waste 
and Porous Surfaces in Accordance with Sec.  761.61(a)(6);
     Subpart P--Sampling Non-Porous Surfaces for Measurement-
Based Use, Reuse, and On-Site or Off-Site Disposal Under Sec.  
761.61(a)(6) and Determination Under Sec.  761.79(b)(3);
     Subpart R--Sampling Non-Liquid, Non-Metal PCB Bulk Product 
Waste for Purposes of Characterization for PCB Disposal in Accordance 
With Sec.  761.62, and Sampling PCB Remediation Waste Destined for Off-
Site Disposal, in Accordance With Sec.  761.61; and
     Subpart T--Comparison Study for Validating a New 
Performance-Based Decontamination Solvent under Sec.  761.79(d)(4).
    These modifications to 40 CFR part 761 can be found in the 
regulatory text section towards the end of this final rule; the 
specific sections of the PCB regulations affected by these changes are 
Sec. Sec.  761.61(a)(5)(i)(B)(2)(iv), 761.253, 761.272, 761.292, 
761.358, and 761.395.
    EPA is adding Methods 3541, 3545A, and 3546 to the PCB regulations 
for extraction of PCBs from solid matrices for several reasons, 
including applicability of the methods to PCBs, frequency of use in EPA 
and commercial laboratories, and existing data supporting the 
effectiveness of the methods. EPA finds, based on reasonably available 
information, that these methods are technically sound for the 
extraction of PCBs from solid matrices. In addition, EPA is adding 
Methods 3510C, 3520C, and 3535A to the PCB regulations for extraction 
of PCBs from aqueous matrices because the PCB Regulations do not 
specify extraction methods for aqueous matrices. EPA finds, based on 
reasonably available information, that these methods are technically 
sound for the extraction of PCBs from aqueous matrices. The technical 
data and rationale for adding these methods to the PCB regulations can 
be found in Section III.A. Expand Available Extraction Methods for PCBs 
of the proposed rule ``Alternate PCB Extraction Methods and Amendments 
to PCB Cleanup and Disposal Regulations'' (86 FR 58730), which is 
included in the docket for this final rulemaking.
Discussion of the Public Comments
    Public comments supported the Agency's proposal to add Method 3541 
(Automated Soxhlet Extraction), Method 3545A (Pressurized Fluid 
Extraction), and Method 3546 (Microwave Extraction) for extraction of 
PCBs from solid matrices; and Method 3510C (Separatory Funnel Liquid-
Liquid Extraction), Method 3520C (Continuous Liquid-Liquid Extraction), 
and Method 3535A (Solid-Phase Extraction) for extraction of PCBs from 
aqueous matrices. Specifically, commenters appreciated the increased 
flexibility of extraction methods, higher efficiency of the methods, 
reduced laboratory cost, and reduced waste.
    EPA agrees with the public comments and is therefore finalizing its 
proposal to add these methods to the regulations. EPA finds, based on 
reasonably available information, that expanding the options for 
alternative extraction methods in the PCB regulations will help the 
regulated community investigate, clean up and dispose of PCB waste more 
quickly, efficiently, and economically, and in a more environmentally 
sound manner.
Background on Extraction Methods for PCBs
    The regulated community has long expressed interest in the 
availability of alternative extraction methods beyond the two 
previously allowed under the PCB regulations--Method 3540C (Soxhlet 
Extraction), which is commonly referred to as ``Manual Soxhlet 
Extraction'', and Method 3550B (Ultrasonic Extraction).\12\ In 
addition, because Ultrasonic Extraction methods do not use heat to 
speed up extraction kinetics or improve extraction efficiency, and the 
contact time with the solvent is relatively short, they may result in 
low bias measurements in some sample types, such as caulk and clay. In 
addition, published studies indicate that Method 3550B has the 
potential to produce low bias measurements in some solid matrices 
compared to other extraction techniques. For more information on this 
issue, see Section III.B. Update and Limit the Use of Ultrasonic 
Extraction of this final rule.

Members to Use Automated Soxhlet Extraction (Method 3541) in 
Connection with June 10, 2014 Risk-Based Approvals to Dispose of 
Polychlorinated Biphenyl (PCB) Remediation Waste''; March 2015.
---------------------------------------------------------------------------

    Manual Soxhlet Extraction was invented in the late 1800s, and the 
revised Method 3540C was created in 1996. It is a long-standing, 
effective method for PCB extraction from solid matrices; however, it 
has slowly been replaced by newer methods in both EPA and commercial 
laboratories over time.\13\ This transition has caused problems with 
the availability of Manual Soxhlet Extraction in EPA and commercial 
laboratories, which could cause delays in getting samples extracted and 
analyzed in a timely matter. In addition, further delays could result 
because Manual Soxhlet Extraction takes 16-24 hours to complete the 
extraction of a limited number of samples, whereas other methods may 
take only 2-4 hours, or less. Manual Soxhlet Extraction systems also 
typically use heating manifolds with significant footprints that are 
commonly operated in fume hoods to limit operator exposure to solvent 
vapors, which further restricts laboratory capacity using this 
technique.

extraction of solid materials: an outdated technique with a 
promising innovative future.'' Department of Analytical Chemistry, 
Faculty of Sciences, University of Cordoba. Cordoba, Spain. March 
1998.
---------------------------------------------------------------------------

    In addition, none of the previously allowed methods are applicable 
to extraction of PCBs from aqueous samples. Method 8082 was the only 
determinative method listed in the PCB regulations for extraction from 
aqueous matrices and states that ``[a]queous samples may be extracted 
at neutral pH with methylene chloride using either Method 3510 
(separatory funnel), Method 3520 (continuous liquid-liquid extraction), 
Method 3535A (solid-phase

extraction) or other appropriate technique or solvents.''

B. Update and Limit the Use of Ultrasonic Extraction

Provisions in the Final Rule
    EPA proposed to remove Method 3550B (Ultrasonic Extraction) from 
the PCB regulations. However, after reviewing the public comments, EPA 
is, instead, updating references to Method 3550B in the PCB regulations 
to Method 3550C and limiting the use of Method 3550C to wipe samples 
only. Available studies on Ultrasonic Extraction collectively 
demonstrate concerns about the inconsistent performance of the method 
and the robustness of extractions for certain matrices of interest to 
the TSCA PCB Cleanup and Disposal Program for compliance testing. 
However, EPA does not have such concerns about use of Ultrasonic 
Extraction for wipe samples based on reasonably available information.
    The sections of the PCB regulations affected by these changes are 
Sec. Sec.  761.61(a)(5)(i)(B)(2)(iv), 761.253, 761.272, 761.292, 
761.358, and 761.395.
Discussion of the Public Comments
    EPA proposed to remove Method 3550B (Ultrasonic Extraction) from 
the PCB regulations because the extraction efficiency may be more 
variable than other methods and thus it has a higher potential than 
other methods to be conducted improperly. However, several commenters 
opposed removing Method 3550B from the PCB regulations. These 
commenters all considered this method to be appropriate for at least 
some matrix types, such as sand and surface wipe samples. Some comments 
suggested that EPA restrict the use of the method for problematic 
matrices only, such as clay and caulk. Some comments stated that method 
quality controls, such as performance testing, visual observation of 
the extraction, or ability to meet the acceptance criteria for the 
method, were sufficient to identify whether the method is appropriate 
for a given sample. The commenters also voiced concern that removal of 
the method from the PCB regulations could lead to logistical problems 
and increased costs. Several of these commenters proposed updating the 
reference from Method 3550B to Method 3550C, which is an updated 
version of Method 3550B.
    The Agency disagrees with comments that suggest EPA restrict the 
use of Method 3550B or 3550C for problematic matrices only, as it would 
be inefficient and complicated to make such a decision on a case-by-
case basis--for example, by prohibiting the method to be used on 
certain types of soils, or by specifying the maximum silt or clay 
content of soil samples for which the method is permissible to use. The 
Agency also disagrees with comments that the method quality controls 
provide all the information needed to distinguish acceptable and poor 
extraction efficiency since PCBs may be more deeply integrated into 
soils or other solid samples and may be more difficult to efficiently 
extract. Based on the available studies, use of Ultrasonic Extraction 
in some solid matrices is likely to produce low bias measurements that 
are not otherwise identified with the method quality controls. This low 
bias may lead to decision errors that could otherwise be avoided by 
using the alternative extraction methods EPA is adding in this 
rulemaking, all of which use heat and a longer solvent contact time to 
speed up extraction kinetics and improve extraction efficiency.
    However, the Agency agrees with comments indicating the method is 
appropriate for wipe samples, because PCBs do not have the same 
extraction kinetics or extraction efficiency limitations from wipe 
samples containing relatively small amounts of particulates as they may 
have in some types of bulk solid samples (e.g., wet clay or caulk). The 
Agency also agrees with comments proposing that EPA update Method 3550B 
to Method 3550C, which is the updated version of Method 3550B. The 
Agency is therefore allowing use of Method 3550C for wipe samples only. 
Allowing use of this extraction method on wipe samples, which are a 
very commonly extracted item, addresses both commenters' concerns about 
cost and logistical problems that completely removing this extraction 
method from the PCB regulations could cause and the Agency's concerns 
regarding use of this method on other matrices.
Background on This Issue
    Method 3550C (Ultrasonic Extraction) is an updated version of 
Method 3550B. Use of Method 3550B was previously allowed in the PCB 
regulations. The text in Method 3550B and Method 3550C includes caveats 
that ultrasonic extraction may not be as rigorous as other extraction 
methods for soils/solids and highlights the importance of following the 
method explicitly. By comparison, this issue is generally not mentioned 
or highlighted in other SW-846 methods. Method 3550C further 
emphasizes, beyond what is stated in Method 3550B, the crucial 
importance of conducting the method properly, in line with the 
manufacturer's instructions regarding operational settings.\14\ For 
more information on the technical aspects of ultrasonic extraction, see 
Section III.A.2. Technical Summary of Relevant Extraction Methods of 
the proposed rule ``Alternate PCB Extraction Methods and Amendments to 
PCB Cleanup and Disposal Regulations'' (86 FR 58730), which is included 
in the docket for this final rulemaking.
---------------------------------------------------------------------------

    \14\ Section 1.4 of Method 3550C states, ``Because of the 
limited contact time between the solvent and the sample, ultrasonic 
extraction may not be as rigorous as other extraction methods for 
soils/solids. Therefore, it is critical that the method (including 
the manufacturer's instructions) be followed explicitly, in order to 
achieve the maximum extraction efficiency. See Sec. 11.0 for a 
discussion of the critical aspects of the extraction procedure. 
Consult the manufacturer's instructions regarding specific 
operational settings.''
---------------------------------------------------------------------------

C. Revise Available Determinative Methods for PCBs

Provisions in the Final Rule
    EPA proposed to add three determinative methods to the PCB 
regulations: Method 8082A (Polychlorinated Biphenyls (PCBs) By Gas 
Chromatography), Method 8275A (Semivolatile Organic Compounds (PAHs and 
PCBs) In Soils/Sludges and Solid Wastes Using Thermal Extraction/Gas 
Chromatography/Mass Spectrometry (TE/GC/MS)), and Method 1668C 
(Chlorinated Biphenyl Congeners in Water, Soil, Sediment, Biosolids and 
Tissue by HRGC/HRMS).
    EPA also proposed to update the outdated referenced methods in 
Sec.  761.60(g)(1)(iii) from Method 608 to Method 608.3, and Method 
8082 to Method 8082A.
    The Agency is adding Method 8082A to the PCB regulations and 
updating Method 608 to Method 608.3 in Sec.  761.60(g)(1)(iii), as 
proposed. The Agency is not adding Method 8275A or Method 1668C to the 
PCB regulations, due to the public comments summarized below. The main 
deciding factor is that the regulated community expressed satisfaction 
with using Method 8082 and/or Method 8082A for analysis and indicated 
that there is not a need to use other methods on a broad scale. 
Although EPA is not adding Method 8275A and Method 1668C as 
determinative methods to the regulations, the Agency notes that these 
methods, as well as other methods that have been published since the 
proposed rule, such as CWA Method 1628, may be appropriate and useful 
in certain situations. For example, a PCB congener analysis method 
(such as Method 1668C) may be preferred based on the

[[Page 59669]]

formulation of PCBs present in the material being analyzed per Sec.  
761.1(b)(2) and may be acceptable under a Sec. Sec.  761.60(e), 
761.61(c), 761.62(c), or 761.79(h) approval. EPA notes that a person 
may either conduct a Subpart Q comparison study or submit an 
appropriate application (i.e., under Sec. Sec.  761.60(e), 761.61(c), 
761.62(c) or 761.79(h)) requesting to use an alternative determinative 
method for their project.
    The sections of the PCB regulations affected by these changes are 
Sec. Sec.  761.60(g)(1)(iii), 761.61(a)(5)(i)(B)(2)(iv), 761.253, 
761.272, 761.292, 761.358, and 761.395.
Discussion of the Public Comments
    Commenters generally opposed adding Method 8275A and Method 1668C 
to the PCB regulations but did not object to adding Method 8082A or 
updating Method 608 to Method 608.3.
    Commenters pointed out that Method 8275A has a very small sample 
size (0.003-0.25 grams), which could lead to problems obtaining 
sufficient sensitivity. Comments also noted that testing such a small 
sample mass may lead to greater concerns about whether sample 
measurements are representative. Other solid sample preparation methods 
included in this rule specify a sample size of 10-30 grams, which is 
less likely to be subject to subsampling bias. In addition, comments 
noted that Method 8275A is not specific to quantitative analysis of 
PCBs as it was validated for simultaneous analysis of select PCB 
congeners and polycyclic aromatic hydrocarbons (PAHs). The comments 
also indicated that there is a lack of commercial laboratory capacity 
to perform this method, and that the method is not available at any 
National Environmental Laboratory Accreditation Program (NELAP) 
accredited laboratories. The comments also expressed concern that the 
drying and sieving process for the method could result in volatile loss 
of mono- and di-chlorobiphenyls, which is a common problem for any 
method which uses air drying. The comments identified that EPA Method 
8275A has a limited scope of target analytes, and the method only 
specifically includes 19 out of 209 PCB congeners. Lastly, the comments 
expressed concern about the use of isotopically labeled PAHs in Method 
8275A as internal standards for PCBs, which may lead to measurement 
bias if they do not perform similarly in a given sample. Considering 
these comments, EPA has decided not to finalize changes related to 
Method 8275A.
    Regarding Method 1668C, commenters were primarily concerned about 
the availability and cost of using this method. Comments indicated that 
the high-resolution mass spectrometer used for this method is not 
widely available, and that the analytical costs are high with long 
turnaround times. The commenters were concerned about the parts-per-
quadrillion detection limits, which are orders of magnitude more 
sensitive than typically needed to demonstrate compliance with the PCB 
regulations. The comments also noted that, due to these very low 
detection limits, this method is more likely to experience laboratory 
background contamination which could lead to problems with data 
interpretation. The commenters were also concerned with the fact that 
the method validation study for Method 1668C did not include soil or 
sediment matrices, and the method does not identify how to report total 
PCBs. Lastly, the comments noted that the regulated community never 
expressed concerns regarding availability of determinative methods 
beyond EPA Method 8082 and/or EPA Method 8082A. In light of these 
comments, EPA has decided not to finalize changes related to Method 
1668C.
    EPA did not receive any substantive comments on its proposal to 
update Method 608 to Method 608.3 and Method 8082 to Method 8082A in 
Sec.  761.60(g)(1)(iii), and thus is finalizing those changes largely 
as proposed.
Background on This Issue
    Previously, the PCB regulations listed Method 8082 (Polychlorinated 
Biphenyls (PCBs) by Gas Chromatography) as the only determinative 
method for PCB samples.\15\ The only exception in the PCB regulations 
was at Sec.  761.60(g)(1)(iii), which stated that ``[a]ny gas 
chromatographic method that is appropriate for the material being 
analyzed may be used'' and then listed several available determinative 
methods.\16\ However, this section in the PCB regulations is restricted 
to samples of mineral oil dielectric fluid (MODEF) and waste oil (see 
Sec. Sec.  761.60(g)(1) and 761.60(g)(2)). Previously, all other 
samples were required to be analyzed using Method 8082, and any 
alternative determinative method would require EPA approval. EPA had 
not received any significant concerns from the regulated community 
regarding the availability of determinative methods; however, EPA 
investigated additional determinative methods to include in the 
proposed rulemaking to provide a greater number of technically sound 
options for the regulated community.

Gas Chromatography. Office of Land and Emergency Management, Office 
of Resource Conservation and Recovery, Materials Recovery and Waste 
Management Division (5303P). Washington, DC. December 1996.
    \16\ The regulatory text at Sec.  761.60(g)(1)(iii) previously 
listed the following methods: ``. . . EPA Method 608, 
``Organochlorine Pesticides and PCBs'' at 40 CFR part 136, Appendix 
A;'' EPA Method 8082, ``Polychlorinated Biphenyls (PCBs) by

for Evaluating Solid Waste,'' which is available from NTIS; and ASTM 
Standard D-4059, ``Standard Test Method for Analysis of 
Polychlorinated Biphenyls in Insulating Liquids by Gas 
Chromatography,'' which is available from ASTM.''
---------------------------------------------------------------------------

    Additionally, the methods previously referenced in Sec.  
761.60(g)(1)(iii) were outdated and did not reflect the most current 
versions. By updating these references, EPA is not requiring that only 
the new specifically referenced methods be used, as Sec.  
761.60(g)(1)(iii) provides that ``[a]ny gas chromatographic method that 
is appropriate for the material being analyzed may be used.'' EPA 
believes this update will avoid confusion by referencing the most up-
to-date methods while still allowing flexibility in this regulatory 
provision.

D. Revise Performance-Based Disposal Under Sec.  761.61(b)

Provisions in the Final Rule
    EPA proposed to amend Sec.  761.61(b) to add performance-based 
cleanup standards, while maintaining this option as one which does not 
require prior EPA approval and thus remains an expedient option for 
those entities removing PCB remediation waste from the site. 
Specifically, EPA proposed to amend Sec.  761.61(b) to include explicit 
conditions for on-site remediation and cleanup of PCB remediation 
waste.
    The Agency is finalizing the provisions in Sec.  761.61(b) largely 
as proposed, with some minor changes and clarifications. The final rule 
includes provisions that: (1) establish cleanup levels; (2) prohibit 
use of Sec.  761.61(b) where cleanup sites are near sensitive 
populations or environments; (3) establish verification sampling 
requirements; (4) establish recordkeeping requirements; (5) establish a 
30-day post-cleanup notification requirement; and (6) allow disposal of 
non-liquid PCB remediation waste in RCRA Subtitle C landfills.
    First, EPA is establishing cleanup levels for sites remediated 
under a Sec.  761.61(b) performance-based cleanup. The regulations 
previously did not reference a specific cleanup level. The

[[Page 59670]]

preamble to the proposed PCB Megarule (59 FR 62788, 62796; Dec. 6, 
1994) explained that Sec.  761.61(b) ``could be used where all PCB 
remediation waste would be removed from the environment, or where 
remediation levels were established elsewhere in these rules.'' In 
guidance, EPA has interpreted ``all PCB remediation waste'' to mean PCB 
remediation waste at >1 ppm PCBs.\17\ Identifying a numerical cleanup 
level in the regulations will help responsible parties understand the 
circumstances under which they could expect to have no further cleanup 
responsibility at the site under Sec.  761.61(b). EPA is therefore 
establishing the following cleanup levels directly in Sec.  761.61(b): 
<=1 ppm for bulk PCB remediation waste and porous surfaces; the 
concentrations specified in Sec.  761.79(b)(1) and (2) for liquids; and 
the concentrations specified in Sec.  761.79(b)(3) for nonporous 
surfaces. See Sec.  761.61(b)(1)(ii).
---------------------------------------------------------------------------

    \17\ Managing Remediation Waste From Polychlorinated Biphenyls 
(PCBs) Cleanups, https://www.epa.gov/pcbs/managing-remediation-waste-polychlorinated-biphenyls-pcbs-cleanups.
---------------------------------------------------------------------------

    Second, EPA is adding an applicability provision in Sec.  761.61(b) 
to exclude the use of Sec.  761.61(b) at sites with specific 
characteristics that merit additional consideration by EPA. In the PCB 
Megarule (63 FR 35384; June 29, 1998), EPA established that certain 
types of sensitive environments and populations would not be well-
served by the cleanup levels prescribed in Sec.  761.61(a)(4) and 
excluded those sites from the applicability of Sec.  761.61(a). EPA 
also identified certain types of sites that, while subject to Sec.  
761.61(a), may call for more stringent cleanup levels. See Sec.  
761.61(a)(1) and (a)(4)(vi). The PCB Spill Cleanup Policy includes 
similar provisions. See Sec.  761.120(a)(2) and (d)(2). Because 
performance-based cleanup under Sec.  761.61(b) will not require 
consultation with EPA, the Agency is establishing a list of objective 
characteristics that excludes a site for cleanup using performance-
based cleanup standards. This list largely mirrors the applicability 
section in Sec.  761.61(a)(1) and the characteristics in Sec. Sec.  
761.61(a)(4)(vi), 761.120(a)(2), and 761.120(d)(2) of sites that may 
require more stringent cleanup levels or site-specific determinations. 
It also excludes sites where PCB remediation waste is found within the 
100-year floodplain, which allows EPA to give additional consideration 
to the protection of waterways through cleanup under Sec.  761.61(a) 
and/or Sec.  761.61(c), and to the impacts of climate change on the 
spread of PCB contamination through flooding. See Sec.  
761.61(b)(1)(i).
    Third, EPA is requiring verification sampling in accordance with 
the PCB regulations to ensure that the cleanup levels established in 
Sec.  761.61(b) have been met. Verification sampling must be conducted 
in accordance with Subpart O for bulk PCB remediation waste and porous 
surfaces, Subpart P for nonporous surfaces, and Sec.  761.269 for 
liquid PCB remediation waste. The concentration in every required 
sample analysis result must be below the specified cleanup levels for 
the cleanup to be complete. See Sec.  761.61(b)(1)(iii).
    Fourth, EPA is incorporating explicit recordkeeping requirements 
into performance-based cleanup. Previously, responsible parties using 
Sec.  761.61(b) were only subject to the applicable recordkeeping 
requirements in Sec.  761.180(a) for PCB remediation waste shipped off-
site. Under the new provisions for performance-based cleanup, 
responsible parties must follow the recordkeeping requirements in the 
PCB Spill Cleanup Policy at Sec.  761.125(c)(5) in addition to the 
requirements in Sec.  761.180(a). See Sec.  761.61(b)(1)(iv).
    Fifth, EPA is incorporating a 30-day post-cleanup notification 
requirement into the performance-based cleanup provisions. Under 
performance-based cleanup and disposal, sites may be remediated without 
EPA involvement. Post-cleanup notification allows regulators to 
evaluate performance to ensure that conditions, such as cleanup levels, 
are met. The notification must include information about the site and 
point of contact, the disposal facility and waste shipments, a summary 
of the required records, and a certification, as defined in Sec.  
761.3, from the responsible party. While EPA proposed to require 
responsible parties to send a notification to EPA within 14 days of the 
final shipment of waste offsite for disposal from a site cleaned up 
under Sec.  761.61(b), based on the public comments summarized below, 
this final rule revises the notification period to 30 days. See Sec.  
761.61(b)(1)(v).
    Sixth, EPA is adding a RCRA Subtitle C landfill disposal option for 
non-liquid PCB remediation waste under Sec.  761.61(b). RCRA Subtitle C 
landfills are already allowed to be used for the disposal of bulk PCB 
remediation waste under Sec.  761.61(a)(5)(i)(B)(2)(iii) and for PCB 
bulk product waste under Sec.  761.62(a)(3). EPA has previously stated 
in the preamble to the PCB Megarule that ``EPA added RCRA Subtitle C 
landfills as a disposal option for PCB bulk product waste because they 
are designed and operated in the same manner as TSCA chemical waste 
landfills.'' \18\ As discussed further below, RCRA Subtitle C and TSCA 
chemical waste landfill regulations authorize the imposition of 
comparable protective conditions, and EPA believes that allowing this 
waste to go to RCRA Subtitle C landfills is protective and presents no 
unreasonable risk to human health or the environment. Moreover, since 
EPA has already determined that RCRA Subtitle C landfills are 
protective for PCB bulk product waste, which typically contains very 
high concentrations of PCBs, the Agency finds that disposal of non-
liquid PCB remediation waste in RCRA Subtitle C landfills would also be 
protective, as non-liquid PCB remediation waste typically contains 
concentrations of PCBs similar to or lower than PCB bulk product waste. 
By adding these landfills to the list of allowable disposal options for 
certain PCB remediation wastes, EPA anticipates that transportation 
costs will decrease as the distance to the closest allowable disposal 
option diminishes. Furthermore, the disposal cost per ton of non-
liquid, nonhazardous PCB waste is generally lower at RCRA Subtitle C 
landfills than it is at TSCA chemical waste landfills. More information 
on the estimated costs is available in the Economic Assessment. See 
Sec.  761.61(b)(2)(ii)(A).
---------------------------------------------------------------------------

    \18\ 63 FR 35384, 35410-35411; June 29, 1998.
---------------------------------------------------------------------------

    Finally, EPA is revising the language in Sec.  761.125(a)(2) of the 
PCB Spill Cleanup Policy to ensure that the addition of RCRA Subtitle C 
landfills to Sec.  761.61(b) does not affect the Spill Cleanup Policy. 
Expanding the disposal options available under the Spill Cleanup Policy 
is not an objective of this rulemaking and is outside the scope of this 
rulemaking. While EPA proposed to revise the language in the Spill 
Cleanup Policy to specify that only disposal facilities with TSCA 
approvals issued under Subpart D of the PCB regulations could be used 
for disposal of cleanup debris and other materials resulting from 
cleanup under the Policy, based on the public comment summarized below, 
EPA has modified the revision to ensure that Subpart D storage and 
disposal options other than disposal in RCRA Subtitle C landfills 
remain. See Sec.  761.125(a)(2).
    EPA notes that the above changes to Sec.  761.61(b) will not impact 
a responsible party's ability to pair performance-based disposal under 
Sec.  761.61(b)(2) with on-site cleanup under Sec.  761.61(a), Sec.  
761.61(c), or Sec.  761.77 (e.g., state-authorized cleanup under a 
coordinated approval). The regulatory text explicitly preserves the 
ability to use

[[Page 59671]]

Sec.  761.61(b)(2) solely as a disposal provision. See introductory 
paragraph in Sec.  761.61(b).
    For more information on the changes to Sec.  761.61(b), see Section 
III.D. Revise Performance-Based Disposal Under Sec.  761.61(b) of the 
proposed rule ``Alternate PCB Extraction Methods and Amendments to PCB 
Cleanup and Disposal Regulations'' (86 FR 58730), which is included in 
the docket for this final rulemaking.
Discussion of the Public Comments
    Comments were supportive of EPA's proposal to establish cleanup 
levels for sites remediated under a Sec.  761.61(b) performance-based 
cleanup, and EPA is finalizing this change as proposed.
    EPA proposed to limit applicability of Sec.  761.61(b) at sites 
with characteristics that may warrant more stringent cleanup levels or 
site-specific determinations. Several commenters expressed concern that 
prohibiting use of Sec.  761.61(b) at sites that are adjacent to, 
contain, or are proposed to be redeveloped to contain the sensitive 
populations or environments listed in Sec.  761.61(b)(1)(i)(A)(7) 
unnecessarily limits the applicability of the Sec.  761.61(b) 
performance-based cleanup option and that the Sec.  761.61(b) cleanup 
levels will ensure no unreasonable risk at these sites. EPA disagrees 
with these comments. In EPA's experience addressing these types of 
sites under Sec.  761.61(c), EPA frequently sees complex risks and 
exposure pathways that require extensive collaboration between EPA and 
responsible parties. Based on this experience, the Agency does not have 
confidence that these sites could be protectively managed under the 
performance-based cleanup option without EPA involvement and believes 
that the Sec.  761.61(b) applicability provisions, which largely mirror 
existing provisions in Sec. Sec.  761.61(a)(1), 761.61(a)(4)(vi), 
761.120(a)(2), and 761.120(d)(2), are appropriately limited. EPA does, 
however, recognize the need for clarification in Sec.  
761.61(b)(1)(i)(A)(7) based on comments that questioned whether the 
term ``adjacent to'' in that provision referred to adjacency to a 
cleanup site or an entire property or facility containing a cleanup 
site. EPA has revised Sec.  761.61(b)(1)(i)(A)(7) to clarify that the 
provision refers to a cleanup site, as defined in Sec.  761.3.
    EPA proposed to add verification sampling requirements to Sec.  
761.61(b). Some commenters sought flexibility in verification sampling 
to account for site-specific circumstances and for other reasons. While 
EPA recognizes the desire for flexibility, because Sec.  761.61(b) is a 
self-implementing cleanup option without EPA involvement, the Agency 
believes that prescriptive verification sampling requirements are 
appropriate, and EPA is finalizing this change as proposed.
    EPA proposed to add recordkeeping requirements from Sec.  
761.125(c)(5) of the PCB Spill Cleanup Policy to Sec.  761.61(b). EPA 
received no comments regarding these recordkeeping requirements and 
thus is finalizing this change as proposed.
    EPA proposed to add a post-cleanup notification requirement to 
Sec.  761.61(b) that would require notification within 14 days of the 
final shipment of waste offsite for disposal from a site cleaned up 
under Sec.  761.61(b). Commenters considered the 14-day notification 
period to be too short and sought either 30 or 60 days. EPA agrees with 
commenters on the need for more time to obtain all necessary 
information to include in the notification, including processing 
verification samples and confirming the manifests. EPA is therefore 
finalizing a post-cleanup notification requirement that requires 
notification within 30 days of final shipment of waste offsite for 
disposal from a site cleaned up under Sec.  761.61(b). EPA finds 30 
days will allow sufficient time to obtain all necessary information 
while providing EPA timely notification of cleanups completed under 
Sec.  761.61(b).
    EPA proposed to allow for disposal of non-liquid PCB remediation 
waste in RCRA Subtitle C permitted landfills under Sec.  761.61(b). 
Most of the commenters supported the addition of RCRA Subtitle C 
landfills to the list of allowable disposal options for non-liquid PCB 
remediation waste. One commenter noted potential differences in 
monitoring, recordkeeping, and reporting requirements for PCBs between 
RCRA Subtitle C landfills and TSCA chemical waste landfills. In 
particular, the commenter noted that environmental monitoring 
requirements for RCRA Subtitle C landfills are based on RCRA hazardous 
waste program requirements, which are not the same as the monitoring 
requirements for TSCA chemical waste landfills under Sec.  761.75 
(i.e., surface water, groundwater, leachate, and secondary leachate 
monitoring of PCBs, pH, specific conductance, and chlorinated 
organics). The commenter noted that additional monitoring parameters 
for TSCA chemical waste landfills may include soil, sediment, and 
ambient air monitoring, where necessary, to ensure protection of the 
environment from PCBs. The commenter also noted that in some States, 
PCBs are not a hazardous waste, which could leave State programs with a 
limited ability to implement environmental monitoring of PCBs at RCRA 
Subtitle C landfills.
    PCBs are hazardous constituents under 40 CFR part 261, appendix 
VIII and groundwater monitoring constituents under 40 CFR part 264, 
appendix IX; therefore, they are regulated under the RCRA regulations 
and under facility permits. Specifically, they are subject to the 
comprehensive scheme for detecting and responding to releases to 
groundwater from hazardous waste management units at facilities 
permitted under RCRA Subtitle C. See 40 CFR part 264, subpart F. Among 
other things, the facility must promptly report to the Regional 
Administrator any detected releases (see, e.g., Sec. Sec.  
264.98(g)(1), 264.99(h)) and maintain records of groundwater monitoring 
data (Sec.  264.97(j)). In addition, the RCRA regulations contain 
requirements for a liner system (under Sec.  264.301(a)(1)), leachate 
collection system (under Sec.  264.301(a)(2)), recordkeeping (under 
Sec.  264.73), and reporting (under Sec. Sec.  264.75, 264.76, and 
264.77). Subtitle C landfills must also be permitted under RCRA Sec.  
3005 and 40 CFR part 270. The permit would flesh out these regulatory 
provisions to specify as appropriate, among other things, requirements 
to analyze groundwater samples for PCBs identified as constituents to 
be monitored and monitor amounts of leachate in the leachate collection 
and removal system. In addition to implementing the specific regulatory 
requirements, each permit is required to contain additional terms and 
conditions that EPA or the authorized State determines to be necessary 
to protect human health and the environment. See RCRA Sec.  3005(c)(3); 
40 CFR 270.32(b)(2). This authority is comparable to 40 CFR 
761.75(c)(3)(ii), under which EPA may include in a TSCA chemical waste 
landfill approval any other requirements or provisions that the Agency 
finds are necessary to ensure that operation of the chemical waste 
landfill does not present an unreasonable risk of injury to health or 
the environment from PCBs. It is under this authority that EPA could 
require, for example, air monitoring at a chemical waste landfill, a 
measure identified by the commenter but not specifically required in 
Sec.  761.75. Thus, EPA disagrees that States in which PCBs are not a 
hazardous waste could have limited ability to implement environmental 
monitoring of PCBs at RCRA Subtitle C landfills. Despite a few minor 
variations in monitoring, recordkeeping, and reporting requirements 
specified in the RCRA

[[Page 59672]]

Subtitle C and TSCA chemical waste landfill regulations, the 
regulations authorize the imposition of comparable protective 
conditions, and EPA believes that allowing this waste to go to RCRA 
Subtitle C landfills is protective and presents no unreasonable risk to 
human health or the environment.
    EPA proposed to revise the language in Sec.  761.125(a)(2) of the 
PCB Spill Cleanup Policy to ensure that the addition of RCRA Subtitle C 
landfills to Sec.  761.61(b) would not affect the Spill Cleanup Policy. 
Specifically, EPA proposed to revise the language in the Spill Cleanup 
Policy to specify that only disposal facilities with TSCA approvals 
issued under Subpart D of the PCB regulations could be used for 
disposal of cleanup debris and other materials resulting from cleanup 
under the Policy. One commenter warned that the revision, as proposed, 
would inadvertently curtail the storage and disposal options for 
cleanup debris and other materials under the Policy. EPA agrees with 
the comment and has modified the revision to specifically exclude 
disposal of cleanup debris and other materials in RCRA Subtitle C 
landfills but allow all other storage and disposal conducted in 
accordance with the provisions of 40 CFR part 761, subpart D. See Sec.  
761.125(a)(2).
    Finally, EPA's request for comments on requiring a Sec.  761.61(b) 
pre-cleanup notification yielded overwhelmingly opposing comments. 
Commenters raised concerns that a pre-cleanup notification would cause 
unnecessary delay and negate one of the primary benefits of carrying 
out performance-based cleanups, which is the ability to perform the 
cleanup without EPA involvement. EPA agrees these concerns have merit 
and has decided to take no further action on this issue.
Background on the Issue
    There are three options for addressing PCB remediation waste, 
listed in Sec.  761.61 under paragraphs (a), (b) and (c). Previously, 
Sec.  761.61(b) prescribed disposal methods for liquid and non-liquid 
PCB remediation waste but did not explicitly require or refer to 
cleanup requirements or cleanup levels in the regulations. In contrast, 
the PCB remediation waste option in Sec.  761.61(a) for ``self-
implementing on-site cleanup and disposal of PCB remediation waste'' 
describes in detail the requirements for notification, site 
characterization, cleanup levels, cleanup verification, disposal 
options, and more. The option in Sec.  761.61(c) for ``risk-based 
disposal approval'' allows a person to apply for a risk-based approval 
to sample, cleanup, or dispose of PCB remediation waste in a manner 
other than prescribed in paragraphs (a) or (b). The language of Sec.  
761.61(b) thus did not conform to the other two options in that the 
provision did not state the removal requirements of PCB remediation 
waste at any specified concentration nor did it provide for procedures 
to demonstrate that on-site cleanup is complete.
    Before this rulemaking, EPA had stated in guidance related to Sec.  
761.61(b) that to be completely unregulated for disposal off-site 
without an approval from EPA, PCB remediation waste must contain <1 ppm 
PCBs, and that the concentration must not be the result of dilution 
during remediation (e.g., by mixing contaminated soil with clean soil 
during excavation).\19\ Similarly, if someone were to use Sec.  
761.61(b) for disposal of waste but leave PCB remediation waste on-site 
>1 ppm, they would still have TSCA obligations for those remaining 
materials.\20\

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

    While EPA's regulatory text and preamble statements refer to 
Sec. Sec.  761.61(a), (b), and (c) as three alternatives for PCB 
cleanup and disposal, the previous absence of cleanup provisions, such 
as cleanup levels and sampling requirements, in Sec.  761.61(b) made it 
challenging to determine that on-site cleanup is complete and the site 
is authorized for use under Sec.  761.30(u).21 22 Clear 
regulatory requirements are warranted as EPA estimates that 50 to 60 
million kilograms of PCB remediation waste are generated at 430 to 460 
sites cleaned up under Sec.  761.61(b) each year.\23\

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

    While the new conditions for performance-based cleanup will require 
additional effort on the part of responsible parties, the conditions 
will also provide them confidence that they are satisfying the 
regulatory requirements. As always, failure to properly characterize 
PCBs on site is not a defense for noncompliant cleanup and disposal. 
Liability for ensuring compliance with Sec.  761.61(b), performance-
based cleanup and disposal, lies with the responsible party. In 
addition, while the revisions to Sec.  761.61(b) are designed to be 
fully self-implementing, if the remediating party has questions as to 
whether a site qualifies to be cleaned up under Sec.  761.61(b)(1)(i) 
of this provision, it would be in the remediating party's best 
interest, from a compliance assurance perspective, to contact the 
appropriate EPA Regional PCB Coordinator prior to commencing the 
cleanup and disposal activities. See EPA's PCB website for a list of 
the EPA Regional PCB Coordinators: www.epa.gov/pcbs/program-contacts.

E. Remove Regulatory Provision Allowing Disposal of PCB Bulk Product 
Waste as Roadbed

Provisions in the Final Rule
    The Agency is removing the option provided for in Sec.  
761.62(d)(2) to dispose of PCB bulk product waste under asphalt as 
roadbed material, as proposed. The Agency cannot determine that the 
practice presents no unreasonable risk of injury to health or the 
environment.
Summary of the Public Comments
    The public comments were supportive of removing the regulatory 
provision allowing the disposal of PCB bulk product waste as roadbed 
material. One commenter sought confirmation that this change will not 
impact PCB bulk product waste that was previously and lawfully disposed 
of as roadbed material under this option. EPA confirms that while the 
PCB regulations no longer allow disposal of PCB bulk product waste 
under asphalt as roadbed as of the effective date of this final 
rulemaking, this change does not have retroactive effect.
Background on the Issue
    EPA established a provision allowing for disposal of PCB bulk 
product waste as roadbed material in the 1998 PCB Megarule. In the 
preamble for that rule, EPA stated that ``[b]ecause these disposal 
options have been restricted to materials that do not leach and because 
other potential routes of exposure have been controlled, EPA has 
concluded that the risk from these disposal options is the practical 
equivalent of disposal in a landfill as required in Sec.  761.62(b)(1), 
and therefore that this risk is not unreasonable.'' \24\ Since 1998, 
the assumption that PCBs do not migrate from PCB bulk product waste has 
been proven incorrect in many scenarios.\25\ For example, studies show 
that caulk containing PCBs degrades, releasing PCBs to the air, 
stormwater, and

[[Page 59673]]

adjacent soil.\26\ Considering these studies, EPA questions whether 
potential leaching of PCBs from PCB bulk product waste used as roadbed 
material could lead to environmental releases of PCBs and potential 
exposures to humans and wildlife. As a result, EPA no longer has a 
basis to support the determination of no unreasonable risk of injury to 
health or the environment that the Agency made in 1998. EPA further 
believes that this disposal option is not widely used.

F. Add Flexible Provisions for Emergency Situations

Provisions in the Final Rule
    EPA is adding new provisions for emergency situations under Sec.  
761.66 to allow individuals to request a waiver from specific 
requirements of Sec. Sec.  761.60, 761.61, 761.62, and 761.65, when 
necessitated by an emergency situation. EPA is also adding two 
provisions to the existing PCB Spill Cleanup Policy in 40 CFR part 761, 
subpart G, that allow for more flexible requirements for cleanup of 
spills caused by and managed in emergency situations. Additionally, EPA 
is establishing a definition for ``emergency situation'' to clarify the 
applicability of these changes.
    The Agency is also adding a provision to remind the regulated 
community that they must abide by all other applicable Federal, State, 
and local laws and regulations when conducting activities under these 
emergency provisions.
a. Definition of ``Emergency Situation''
    EPA is adding a definition for ``emergency situation'' to 
Sec. Sec.  761.3 and 761.123. Specifically, EPA is defining ``emergency 
situation'' as ``adverse conditions caused by manmade or natural 
incidents that threaten lives, property, or public health and safety; 
require prompt responsive action from the local, State, Tribal, 
territorial, or Federal government; and result in or are reasonably 
expected to result in: (1) A declaration by either the President of the 
United States or Governor of the affected State of a natural disaster 
or emergency; or (2) an incident funded under the Federal Emergency 
Management Agency (FEMA) via a Stafford Act disaster declaration or 
emergency declaration. Examples of emergency situations may include 
civil emergencies or adverse natural conditions, such as hurricanes, 
earthquakes, or tornados.'' EPA is establishing this definition because 
it is sufficiently broad to capture a wide range of emergencies that 
would be likely to significantly impact the cleanup and disposal of PCB 
waste. At the same time, the definition is contingent upon a 
declaration of disaster or emergency from an established authority, 
which are generally made in an objective manner. In response to a 
public comment indicating that such declarations are sometimes made 
well after incidents occur, which could create uncertainty as to 
whether adverse conditions caused by the incident would qualify as an 
emergency situation, EPA has revised the proposed definition to include 
situations that both result in or are reasonably expected to result in 
a declaration.
b. Additional Flexibilities Under the PCB Spill Cleanup Policy for 
Spills Caused by Emergency Situations
    In this rulemaking, EPA is expanding the existing flexibilities in 
the PCB Spill Cleanup Policy in 40 CFR part 761, subpart G to be 
available in all emergency situations, rather than on a case-by-case 
basis. First, EPA is allowing the responsible party to clean up a spill 
caused by an emergency situation based on the as-found PCB 
concentration when the source concentration cannot readily be 
determined, as is common in emergency situations. See Sec.  
761.120(c)(2)(i) and the definition of ``spill'' in Sec.  761.123.
    Second, EPA is adding flexibility to the timeframe for completing 
notification under the PCB Spill Cleanup Policy. Generally, the PCB 
Spill Cleanup Policy specifies that notification be made within 24 
hours after the responsible party was notified or became aware of the 
spill. See Sec.  761.125(a)(1). When the Policy is used for cleanup 
activities undertaken directly in response to spills caused by 
emergency situations, EPA is extending the timeframe for reporting. EPA 
proposed to extend the timeframe for reporting to seven days after the 
adverse conditions that prevented communication have ended. However, in 
response to a comment summarized below, EPA is shortening the window to 
48 hours after the adverse conditions that prevented communication have 
ended (e.g., internet and phone lines are down due to an emergency 
situation; once one or the other is back up, notification to EPA is 
required within 48 hours). See Sec.  761.120(c)(2)(ii).
    These flexibilities are being finalized largely as proposed. EPA 
expects that these flexibilities will result in a net benefit in 
protection of health and the environment, given that they allow those 
conducting responses to spills caused by emergency situations to assess 
and dispose of waste more quickly and to prioritize time-sensitive 
remedial actions.
c. Waiver From Various Sampling, Extraction, Analysis, Cleanup, 
Storage, and Disposal Requirements in Emergency Situations
    EPA is creating an option to apply for a waiver from various PCB 
waste management requirements when necessitated by emergency 
situations. Responsible parties will be able to request a waiver from 
the provisions of Sec. Sec.  761.60, 761.61, 761.62, and 761.65, which 
provide requirements for sampling, extraction, analysis, cleanup, 
storage, and disposal of all types of regulated PCB wastes.
    Cleanup and disposal activities often cannot be initiated promptly 
in emergency situations, such as hurricanes or wildfires, due to 
necessary emergency response actions taking place. EPA recognizes that 
spills caused by an emergency situation may not be discovered or be 
able to be cleaned up until after the emergency ends or until after the 
initial emergency response. EPA regularly negotiates and implements 
special arrangements during emergency situations on a case-by-case 
basis, which can delay implementation of remedial actions. EPA is 
therefore modifying the PCB regulations to allow the person managing 
the cleanup and/or disposal of PCB waste caused by an emergency 
situation to request waivers from applicable PCB sampling, extraction, 
analysis, cleanup, storage, disposal and other regulatory requirements 
when there is an emergency situation and the existing regulatory 
requirements (e.g., timeframes, sampling protocols) are impracticable 
due to the nature of the emergency situation. This waiver option is 
being finalized as proposed, except as described in the response to 
comments below.
Discussion of the Public Comments
    The public comments pertaining to emergency situations were 
generally supportive of most of the provisions and additional 
flexibilities put forward by the Agency in the proposed rulemaking. 
There were three main issues raised by the commenters.
    First, some commenters expressed that the proposed definition of 
``emergency situation'' was too limiting and may leave individuals 
unsure if they would be able to use the flexible

[[Page 59674]]

provisions for emergency situations in Sec.  761.66 and in the PCB 
Spill Cleanup Policy. One commenter stated that emergency and disaster 
declarations may be delayed, even for several weeks, after adverse 
conditions occur and provided several examples where delay has occurred 
in the past. The commenter opposed tying the definition of emergency 
situation to the issuance of a declaration because delays could create 
uncertainty as to whether regulated parties could use the flexible 
provisions for emergency situations when they are most needed. EPA 
recognizes that delays in issuance of declarations could create 
uncertainty and has therefore revised the proposed definition to 
include not only situations that result in declarations, but also 
situations where an individual could reasonably expect a declaration 
will be made. Other commenters requested that EPA broaden the 
definition of ``emergency situation'' to include activities such as 
power restoration and emergency utility repairs. EPA notes that the 
flexible provisions for emergency situations may be used for activities 
involving power restoration and utility repair that are caused by 
emergency situations. However, those activities by themselves do not 
constitute emergency situations that warrant flexibility. EPA does not 
expect there to be barriers to compliance with the regular requirements 
in the normal course of power restoration or utility repairs, such as 
communications lines being fully inaccessible or utilities conducting 
other competing emergency response actions.
    Second, a commenter stated the proposed seven-day timeframe for 
completing notification under the PCB Spill Cleanup Policy would give 
individuals too much time to notify the Agency in an emergency 
situation. The Agency agrees with this commenter and is shortening the 
timeframe to 48 hours, which is now closer in length to the 24-hour 
timeframe for notification under the PCB Spill Cleanup Policy for 
spills not related to emergency situations. See Sec.  761.125(a)(1).
    Third, some commenters were confused by the waiver option and did 
not see how it differed from a formal PCB approval. While the waiver 
request is submitted to and approved by the Regional Administrator, it 
is not a formal PCB approval. The waiver is only for temporary measures 
in emergency situations. Examples of such situations might include 
excavating visibly contaminated soil near storm drains or removing and 
storing leaking electrical equipment that contains PCB oil before the 
remaining oil is released to the environment. As emergency situations 
may be complex and often time-sensitive, the waiver option allows one 
path for entities to request changes to multiple standards at once, 
rather than seeking individual approvals under several regulatory 
standards.
    A comment was received requesting that a copy of the waiver request 
be sent to the Director of the State or Tribal environmental agency. 
The Agency agrees with this change and has incorporated the language 
into the final rule. Therefore, the Agency is finalizing the waiver 
request option generally as proposed with the additional language that 
a copy of the waiver request must be sent to the Director of the State 
or Tribal environmental agency.
    Other comments were either supportive of the proposed changes or 
requested minor changes. One commenter requested that the Agency 
include language to remind the regulated community that they must abide 
by all other Federal, State, and local laws and regulations; the Agency 
agrees with this change and has incorporated the language in the final 
rule.
Background on the Issue
    The TSCA PCB Spill Cleanup Policy was first published on April 2, 
1987 (52 FR 10688), and is codified at 40 CFR part 761, subpart G. The 
Policy establishes criteria to determine the adequacy of the cleanup of 
spills resulting from the release of materials containing PCBs at 
concentrations of 50 ppm or greater which occur after May 4, 1987. The 
PCB Spill Cleanup Policy requires cleanup of PCBs to different levels 
depending upon spill location, the potential for exposure to residual 
PCBs remaining after cleanup, the concentration of PCBs initially 
spilled (high or low concentration), and the nature and size of the 
population potentially at risk of exposure to residual PCBs. The Policy 
applies the most stringent requirements for PCB spill cleanup to non-
restricted access areas where there is a greater potential for human 
exposures to spilled PCBs and less stringent requirements to restricted 
access areas where there is little potential for human exposures.\27\
---------------------------------------------------------------------------

    \27\ 59 FR 62788, 62793; Dec. 6, 1994.
---------------------------------------------------------------------------

    When the spilled material contains 50 to less than 500 ppm PCBs and 
the total quantity of material spilled involves less than 1 pound of 
PCBs, the Policy allows for cleanup in accordance with procedural 
performance requirements (i.e., double wash/rinse for solid surfaces 
and removal of visible traces plus a 1-foot lateral boundary for soil 
and other ground media provided that the minimum depth of excavation is 
10 inches) rather than requiring sampling to verify that numerical 
cleanup standards have been met. When the spilled material contains 
PCBs equal to or greater than 500 ppm PCBs, or the total quantity of 
material spilled containing PCBs at or below 500 ppm involves 1 pound 
or more of PCBs by weight, the Policy provides numerical cleanup 
standards based on the accessibility of the area and the potential for 
human exposure. Post-cleanup sampling is required to verify that the 
cleanup standards have been met.
    EPA may allow flexibility such as less stringent or alternative 
requirements based upon site-specific considerations. See Sec.  
761.120(a)(4). EPA has used this provision to issue storm-specific 
guidance in Regions 4 and 6 for Hurricanes Katrina (2005),28 
Harvey (2017),29 Irma (2017),30 Florence 
(2018),31 Michael (2018),32 Dorian 
(2019),33 34 and Tropical Storm Barry 
(2019).35 36 Generally, EPA extended the time frame for 
notification and allowed spills to be managed based on the as-found 
concentration for spills directly caused by the emergency situation.

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

    EPA recognizes that issuing guidance on a case-by-case basis can 
create some inefficiencies. First, since disasters can develop without 
forewarning, they can put pressure upon EPA to develop the guidance 
quickly so that it may be distributed to the regulated community in 
time for facilities to use it. Also, the fast-paced nature of the 
response to such events means that entities that could use the guidance 
may not become aware that it was issued in time to use

[[Page 59675]]

it. Finally, due to uncertainty regarding whether a guidance document 
will be issued, it is often challenging for regulated facilities to 
include the flexibilities offered in the EPA guidance into their 
disaster preparation protocols. EPA received requests from industry 
requesting a more standardized set of flexibilities, citing several of 
these reasons.
    Independent of EPA's additions above, EPA notes that Sec.  761.61 
currently ``does not prohibit any person from implementing temporary 
emergency measures to prevent, treat, or contain further releases or 
mitigate migration to the environment of PCBs or PCB remediation 
waste.'' This means that immediate measures may be taken to contain 
PCBs during an emergency situation prior to receiving approval from the 
EPA Regional Administrator as described in Sec.  761.66(b).

G. Harmonize General Disposal Requirements for PCB Remediation Waste

Provisions in the Final Rule
    The Agency is finalizing the proposed change to the language in 
Sec.  761.50(b)(3)(ii) by removing the phrase ``at as found 
concentrations >=50 ppm.'' The language now reads: ``(ii) Any person 
responsible for PCB waste that was either placed in a land disposal 
facility, spilled, or otherwise released into the environment on or 
after April 18, 1978, but prior to July 2, 1979, where the 
concentration of the spill or release was >=500 ppm; or placed in a 
land disposal facility, spilled, or otherwise released into the 
environment on or after July 2, 1979, where the concentration of the 
spill or release was >=50 ppm, must dispose of it in accordance with 
either of the following''.
Discussion of the Public Comments
    All of the public comments were either supportive or did not object 
to EPA's proposal to modify the language in Sec.  761.50(b)(3)(ii). EPA 
is thus finalizing this change as proposed.
Background on This Issue
    In the 1998 PCB Megarule, EPA promulgated both the definition of 
PCB remediation waste in Sec.  761.3 and a guide to the cleanup and 
disposal obligations for PCB remediation waste in Sec.  761.50(b)(3). 
At the time of the 1998 PCB Megarule, Sec.  761.50(b)(3) failed to 
account for the fact that disposal of PCBs <500 ppm was not regulated 
between April 18, 1978, (the effective date of the Disposal and Marking 
Rule, which set the 500 ppm threshold) and July 2, 1979 (the effective 
date of the PCB Ban Rule, which replaced the 500 ppm level with 50 
ppm). EPA issued a technical amendment to correct this discrepancy in 
1999 (64 FR 33755; June 24, 1999). The preamble text addressed changes 
made to Sec.  761.50(b)(3)(i), which was amended accordingly. Section 
761.50(b)(3)(ii) was also amended, presumably to correct the same 
discrepancy for the time between April 18, 1978, and July 2, 1979. 
However, the phrase ``at as-found concentrations >=50 ppm'' was added 
to Sec.  761.50(b)(3)(ii) unnecessarily. This addition was apparently 
an error; there is no justification in the preamble for the change, and 
it could be read to cut against the apparent intent to better align 
Sec.  761.50(b)(3) with the definition of PCB remediation waste and the 
general direction in Sec.  761.50(b)(3) that PCB remediation waste ``is 
regulated for cleanup and disposal in accordance with Sec.  761.61.''
    In keeping with the regulatory text overall, preamble and guidance 
statements, and interactions with the regulated community, EPA has not 
interpreted the ``as found'' language in Sec.  761.50(b)(3)(ii) as 
limiting the cleanup and disposal obligations for PCB remediation waste 
created by releases that occurred on or after the dates referenced in 
that clause, where the as-found PCB concentration is <50 ppm. Rather, 
EPA maintains that all materials that fit the definition of PCB 
remediation waste in Sec.  761.3--including materials which are 
currently at any volume or concentration where the original source was 
>=500 ppm PCBs beginning on April 18, 1978, or >=50 ppm PCBs beginning 
on July 2, 1979--are regulated for cleanup and disposal under Sec.  
761.61. The introductory language to Sec.  761.50(b)(3) provides, 
without exception, that ``PCB remediation waste [. . .] is regulated 
for cleanup and disposal in accordance with Sec.  761.61.'' EPA has 
published guidance affirming that PCB remediation waste, even if <50 
ppm, is regulated under Sec.  761.61.\37\ EPA has also issued numerous 
risk-based disposal approvals in the past five years that apply only to 
<50 ppm PCB remediation waste.\38\

    \38\ Nationwide Risk-based PCB Remediation Waste Disposal 
Approvals. https://www.epa.gov/pcbs/nationwide-risk-based-pcb-remediation-waste-disposal-approvals.
---------------------------------------------------------------------------

    In EPA's view, the function of Sec.  761.50(b)(3)(ii) is to clarify 
that PCB remediation waste created by releases that occurred on or 
after the dates referenced in that clause can be managed either in 
accordance with the PCB Spill Cleanup Policy if it meets the criteria 
established in the Policy, as provided in Sec.  761.50(b)(3)(ii)(A); or 
in accordance with Sec.  761.61, as provided in Sec.  
761.50(b)(3)(ii)(B) and the introductory text to Sec.  761.50(b)(3). 
This intention is reflected in the 1998 PCB Megarule preamble, which 
states: ``With regard to sites containing PCB remediation wastes 
generated on or after April 18, 1978, owners or operators of those 
sites now have two choices: they may clean up the wastes in accordance 
with the new Sec.  761.61, or, if applicable, they may clean up the 
wastes in accordance with EPA's Spill Cleanup Policy, part 761, subpart 
G.'' \39\ In contrast, the older PCB remediation waste addressed under 
Sec.  761.50(b)(3)(i) is not eligible for management under the PCB 
Spill Cleanup Policy. Thus, as EPA interprets Sec.  761.50(b)(3)(ii), 
the effect of adding the ``as-found'' limitation to the provision was 
to suggest that PCB remediation waste created by releases that occurred 
on or after the dates referenced in that clause, where the as-found PCB 
concentration is <50 ppm, is not eligible for management under the PCB 
Spill Cleanup Policy, but only under Sec.  761.61 as provided in the 
introductory text. EPA did not intend to so limit the Policy, which 
applies to the cleanup of certain spills resulting from the release of 
materials containing PCBs >=50 ppm but is not dependent on the as-found 
concentrations of the materials contaminated by such spills.

H. Make Changes To Improve Regulatory Implementation

    EPA proposed several supplemental amendments to improve 
implementation of existing requirements, clarify regulatory ambiguity, 
and correct technical errors in the PCB regulations. EPA requested 
comment and is finalizing changes for each item listed below. For more 
information on the proposed changes, see Section III.H. Make Changes to 
Improve Regulatory Implementation of the proposed rule, ``Alternate PCB 
Extraction Methods and Amendments to PCB Cleanup and Disposal 
Regulations'' (86 FR 58730), which is included in the docket for this 
final rulemaking.

plastics. The Agency is modifying the definition of ``non-porous 
surface'' in Sec.  761.3 to include medium-density plastics as an 
example of a non-porous surface.
Discussion of the Public Comments
    The public comments were supportive of adding medium density 
plastics to the definition of a non-porous surface, and thus EPA is 
finalizing this change as proposed.
Background on the Issue
    In December 2018, EPA issued an interpretive letter to the American 
Gas Association which found that medium- and high-density polyethylene 
used in natural gas distribution piping meet the definition of a ``non-
porous surface'' under Sec.  761.3.\40\ EPA found that the study titled 
Assessment of Polychlorinated Biphenyls (PCBs) in Polyethylene (PE) Gas 
Distribution Piping, conducted by NYSEARCH and National Grid, 
demonstrated that the amount of PCB absorption into medium- and high-
density polyethylene pipe was minimal, and penetration of PCBs beyond 
the immediate surface was limited.\41\ EPA is therefore including 
medium-density plastics in the definition of non-porous surface. See 
Sec.  761.3.

2. Temporary Storage in Containers at the Site of Generation
Provisions in the Final Rule
    The PCB regulations permit the storage of bulk PCB remediation 
waste in piles at the site of generation for up to 180 days under Sec.  
761.65(c)(9). In response to requests from generators, EPA is allowing, 
under the same provision, the use of non-leaking, covered containers to 
be used at the site of generation for up to 180 days. Waste stored in 
containers must meet the same criteria as waste stored in piles, and 
thus do not incur additional risk.
Discussion of the Public Comments
    The public comments were all supportive or did not object to 
allowing temporary storage in containers at the site of generation, and 
thus EPA is finalizing this change as proposed. Several comments did 
request clarification on what qualifies as a container, including 
whether a container encompasses drums or roll-off boxes. Drums and 
roll-off boxes which meet the definition of a container under Sec.  
761.65(c)(9) (e.g., constructed of appropriate materials, non-leaking, 
covered) would qualify as a container. EPA is clarifying that under 
this provision a liner is required only for piles, to prevent soil 
contamination, and is not required for containers. Please see 
``Response to Comments on the Proposed PCB Rulemaking'' in the docket 
for further clarification.
3. Language Modifications for Financial Assurance Instruments
Provisions in the Final Rule
    The Agency is finalizing the change to allow the Regional 
Administrator (RA) the flexibility to modify the language required in 
financial assurance instruments for the purposes of implementation 
under TSCA. These changes allow the RA to request modification to the 
terms of those instruments to account for the fact that they are being 
used to fulfill a financial assurance obligation under TSCA; for 
example, modifications may include changes to the instrument wording so 
that references to RCRA are replaced with references to TSCA, or 
changes to the instruments to better comport with the legal authorities 
under, and applicable to, TSCA. The changes are made throughout Sec.  
761.65(g), once for each of the financial instruments. See Sec. Sec.  
761.65(g)(1), 761.65(g)(1)(iv), 761.65(g)(2), 761.65(g)(3)(i), 
761.65(g)(4)(i), 761.65(g)(5), 761.65(g)(6), and 761.65(g)(7).
Discussion of the Public Comments
    EPA received one public comment in support and one public comment 
in opposition to the proposed revision to allow Regional Administrators 
discretion to modify the required language in financial assurance 
instruments. The latter commenter was concerned with the possibility of 
different standards applying in different Regions. However, this is not 
the intention of the change. The wording of the change, ``except when 
the Regional Administrator specifies modifications for the purposes of 
implementation under TSCA,'' that applies to each of the allowed 
financial assurance instruments limits changes to those that are 
necessary for implementation under and in alignment with TSCA. Any 
necessary changes to financial assurance instruments should therefore 
be narrow. Further, the TSCA PCB program is implemented by EPA 
Headquarters and Regions with a high level of coordination; therefore, 
EPA expects any necessary modifications to be broadly and consistently 
applied across the program. EPA is finalizing this change as proposed.
Background on This Issue
    The PCB regulations at Sec.  761.65(g) require commercial storers 
of PCB waste to establish financial assurance for closure of PCB 
storage facilities by choosing from financial assurance mechanisms in 
the RCRA regulations under 40 CFR part 264. Part 264 includes 
prescribed language that must be included in each type of financial 
instrument. Some variation from the RCRA instrument wording may be 
necessary for the purposes of effectuating the financial assurance 
requirements under TSCA. EPA is therefore revising Sec.  761.65(g) to 
allow the RA the flexibility to modify the language required in 
financial assurance instruments for the purposes of implementation 
under TSCA.
5. Remove Manifest Tracking Numbers From Annual Reports
Provisions in the Final Rule
    EPA is removing the provision at Sec.  761.180(b)(3)(ii) requiring 
owners or operators of PCB disposal facilities or commercial storage 
facilities to include in their annual reports lists of manifest 
tracking numbers of signed PCB manifests either received by or 
generated at the facility during that year. The Agency is finalizing 
this change as proposed to reduce the burden on reporting facilities 
and to simplify the annual reporting process. In place of the 
aforementioned requirement, EPA is marking Sec.  761.180(b)(3)(ii) as 
``[Reserved].''
Discussion of the Public Comments
    No commenters were opposed to the removal of manifest tracking 
numbers from the Annual Reports and thus EPA is finalizing this change 
as proposed. Commenters did encourage EPA to look for additional ways 
to coordinate the PCB manifest requirements with EPA's RCRA hazardous 
waste electronic manifest (e-Manifest) system to avoid duplication and 
unnecessary burdens. EPA notes that the Agency recently proposed, in a 
separate rulemaking, further regulatory changes to more closely align 
PCB manifest regulations with the RCRA manifest regulations with 
respect to e-Manifest (87 FR 19290; April 1, 2022). Commenters also 
requested that the owner or operator of a facility should be allowed to 
exclude manifest tracking numbers from their annual document log since 
that information is also uploaded to the e-Manifest system. EPA did not 
propose changes to remove the requirement to

[[Page 59677]]

maintain manifest tracking numbers in the annual document log and thus 
is not making any changes at this time.
Background on This Issue
    As of June 30, 2018, receiving facilities must submit final, signed 
manifests to EPA's e-Manifest system. Since PCB manifests can now be 
obtained from the e-Manifest system, EPA no longer needs this 
information to be submitted as part of the annual reporting 
requirement.
6. Mandatory Form for Annual Reports
Provisions in the Final Rule
    The Agency is finalizing a requirement to use a standard form for 
the submission of annual reports under Sec.  761.180(b)(3). Use of a 
standard form will create a consistent reporting format that will 
reduce burden for EPA and regulated entities.
Discussion of the Public Comments
    Most commenters supported use of a standard form for submission of 
annual reports, and thus EPA is finalizing this change as proposed. EPA 
notes that, one commenter opposed the standard form, asserting that it 
would be a burden to the facilities that had adopted their own format 
and methods for compiling the annual report. While EPA acknowledges 
that facilities will have to adjust their current practices to adopt 
the new form, the Agency finds that a standard form will reduce burden 
overall and result in more complete and higher quality data submitted. 
Another commenter was amenable to the addition of the form but did not 
agree that use of the form should be mandatory; specifically, the 
commenter noted that if annual reports contain all required 
information, failure to use the standard form should not result in a 
TSCA violation. The Agency disagrees with this comment and believes 
that mandatory use of the form for submission of annual reports is 
appropriate. This is consistent with how EPA requires use of other 
forms, such as the Uniform Hazardous Waste Manifest form (EPA form 
8700-22) and the RCRA Subtitle C Site Identification Form (EPA form 
8700-12). Moreover, allowing use of the standard form on a voluntary 
basis would likely diminish the impacts of the form on burden reduction 
and submission of more complete and higher quality data. Some 
commenters also requested a two-year transition period before use of 
the form becomes mandatory. EPA finds that an additional transition 
period is not necessary given that use of the form will not be required 
until the first July 15 (i.e., the due date for the annual report) 
following the effective date of the rulemaking. Another commenter asked 
if EPA could develop a standardized online reporting portal; EPA 
acknowledges this comment and may consider it for future implementation 
efforts.
Background on This Issue
    While Sec.  761.180(b)(3) describes the information EPA requires in 
the annual report, it does not specify a format. This lack of clarity 
could lead to confusion for regulated entities. Use of the form will 
standardize the format and improve data quality, allowing EPA to 
process the reports in less time. The form will also reduce the 
reporting burden on members of the regulated community who submit more 
than the required information, such as facilities that send copies of 
every manifest instead of every manifest tracking number. Furthermore, 
the instructions for the form clarify EPA's expectations; for example, 
facilities should report ``zero'' in all categories for which they did 
not manage PCB waste in that calendar year. At present, many facilities 
omit categories in annual reports, making it unclear as to whether this 
is an oversight or an indication that the categories do not pertain to 
them.
7. PCB Waste Categories on the Manifest and Annual Reports
Provisions in the Final Rule
    The Agency is finalizing changes to the categories of PCB waste 
specified by the generator on the manifest to align with the categories 
of PCB waste specified by the commercial storer or disposer in the 
annual report. Specifically, EPA is modifying the categories of PCB 
waste in Sec.  761.207(a) to list the five categories from Sec.  
761.180(b)(3)(iii)-(vi): ``bulk PCBs,'' ``PCB Transformers,'' ``PCB 
Large High or Low Voltage Capacitors,'' ``PCB Article Containers,'' and 
``PCB Containers.'' In response to comments summarized below, the 
Agency is also adding a sixth category of PCB waste in Sec.  761.207(a) 
and Sec.  761.180(b)(3)(iii)-(vi): ``Other.'' Additional required data 
elements (e.g., unique identification number, weight in kilograms, date 
removed from service) remain the same. EPA notes that the additional 
category of PCB waste on the manifest, ``Other,'' does not impact the 
categories of PCB waste submitted in the annual document log under 
Sec.  761.180(a)(2). EPA is also removing references to instructions in 
the appendix of 40 CFR part 262 because these instructions were removed 
from the regulations and are instead available on EPA's website.\42\
---------------------------------------------------------------------------

    \42\ https://www.epa.gov/hwgenerators/uniform-hazardous-waste-manifest-instructions-sample-form-and-continuation-sheet.
---------------------------------------------------------------------------

Discussion of the Public Comments
    The commenters were divided on this change. One commenter fully 
supported this change. Another commenter did not object to the revision 
of PCB waste categories on the manifest but requested that stakeholders 
be given enough time to prepare for the changes and that the changes 
only be applicable to manifests prepared after the effective date of 
the rule. EPA confirms that the revised categories of PCB waste are 
only applicable to manifests prepared after the effective date of the 
rule. The Agency also notes that the effective date of this rule is 180 
days after the date of publication in the Federal Register, which 
should provide sufficient time for stakeholders to prepare. One 
commenter was concerned that none of the proposed categories covered 
PCB-Contaminated transformers with concentrations >=50 to <500 ppm, 
which previously were classified under the category ``PCB Article not 
in a PCB Container or PCB Article Container,'' which EPA is 
eliminating. Another commenter requested clarification from the Agency 
on whether PCB-Contaminated transformers and other electrical equipment 
would be required to be identified on the manifest, as it is not 
included in the five proposed categories. To address these 
aforementioned comments, the Agency is adding an additional category of 
PCB waste to the manifest (and the annual report), ``Other.'' EPA also 
notes that PCB-Contaminated transformers and other electrical equipment 
will be required to be marked on the manifest under this new category. 
Another commenter opposed the requirements in Sec.  761.207(a)(4) and 
(a)(5) to specify the type of PCB waste for each PCB Article Container 
or PCB Container, asserting that such information takes up already 
limited space on the manifest form and is unnecessary because it can be 
found in waste characterization forms on-site at generator and 
treatment or disposal facilities. EPA disagrees with the comment, 
noting that previous requirements for the now-eliminated ``PCB Article 
Container or PCB Container'' category of PCB waste also required 
specification on the manifest of the type of PCB waste for each PCB 
Article Container or PCB Container. EPA believes that such information 
on the manifest is valuable because this allows EPA to track the type 
of waste in

[[Page 59678]]

e-Manifest without having to obtain waste characterization forms, which 
are not easily accessed.
Background on This Issue
    Previously, Sec.  761.207(a) required PCB waste to be listed on the 
manifest as either ``bulk PCBs,'' ``PCB Article Container or PCB 
Container,'' or ``PCB Article not in a PCB Container or PCB Article 
Container.'' These categories, however, did not match the categories of 
PCB waste specified by the commercial storer or disposer in the annual 
report under Sec.  761.180(b)(3). Harmonizing these PCB waste 
categories streamlines recordkeeping for commercial storers and 
disposers, while imposing negligible burden on the generators.
8. Define ``As-Found Concentration''
Provisions in the Final Rule
    The Agency is adding a definition of ``as-found concentration'' to 
Sec.  761.3, as proposed. The final definition reads: ``As-found 
concentration means the concentration measured in samples of 
environmental media or material collected in-situ (i.e., prior to being 
moved or disturbed for cleanup and/or disposal), unless otherwise 
specifically provided. For example, media must not be disturbed, nor 
may they be diluted (e.g., excavated, placed on a pile, and sampled 
after such placement), before characterization sampling is conducted. 
Sampling media in piles and existing accumulations would be considered 
``as-found'' if the media were already in piles when the site was first 
visited by the responsible party, such as during the redevelopment of 
abandoned properties with historic PCB contamination. The as-found 
concentration is distinct from the source concentration, which is the 
concentration of the PCBs in the material that was originally spilled, 
released, or otherwise disposed of at the site.''
    The definition clarifies that the as-found concentration must be 
measured from samples collected in-situ, unless otherwise specifically 
provided. Existing accumulations, as described in Sec.  761.340(a) 
would be one such exception. Ex-situ sampling often reduces the 
concentration of PCBs in environmental media through dilution.
Discussion of the Public Comments
    Commenters expressed concerns that the proposed definition of as-
found concentration would be unworkable for situations where soils are 
excavated and generated during emergency underground utility repairs, 
routine maintenance activities, replacement of utility poles damaged by 
weather events, or otherwise generated and tested ex-situ for the 
purposes of characterization for disposal. EPA acknowledges that there 
are scenarios where in-situ sampling to characterize potential PCB 
remediation waste for disposal may not be feasible such as certain 
emergency repair situations. It is EPA's intent to encourage PCB 
sampling of in-situ environmental media prior to making emergency 
repairs if it is feasible to do. If PCBs are discovered after ex-situ 
sampling in an emergency repair scenario, or from materials excavated 
from an area where there was no known PCB use or release, they may be 
disposed of under the performance based disposal requirements of Sec.  
761.61(b)(2), or a person may take additional steps to determine if the 
PCBs are regulated under TSCA (i.e., originated from a regulated source 
or were otherwise potentially diluted from in-situ levels exceeding 50 
mg/kg). If you are uncertain about whether such materials are regulated 
under the TSCA PCB regulations, you are encouraged to consult with your 
Regional PCB Coordinator. EPA believes that routine maintenance 
activities or general utility repairs would not rise to the level of an 
emergency and would provide for the opportunity to perform in-situ 
sampling to check for the presence of PCB contamination prior to soil 
excavation. For scenarios such as downed utility poles which cause 
releases of PCBs or suspected PCBs to the environment, the PCB Spill 
Cleanup Policy in 40 CFR part 761, subpart G offers an approach for 
such scenarios.
    In addition, commenters stated that the definition of as-found 
concentration should not be restricted to in-situ sampling due to the 
heterogeneous nature of PCB contamination at cleanup sites. EPA 
acknowledges that PCB remediation waste such as soils can be 
heterogeneous; however, the regulations require adequate site 
characterization to determine the concentration and extent of PCB 
contamination at a cleanup site. The Subpart N cleanup site 
characterization sampling procedures were included in the 1998 PCB 
Megarule as an optional method for collecting new data at a cleanup 
site under 40 CFR 761.61. The regulations do not preclude a person from 
using a characterization sampling procedure designed to reduce the 
deleterious effects that soil heterogeneity has on environmental data 
prior to soil excavation.
    EPA finds that no changes are necessary based on public comments, 
as addressed above. Therefore, EPA is finalizing the definition of 
``as-found concentration'' as proposed.
Background on This Issue
    In the 1998 PCB Megarule, EPA allowed for a variance from the anti-
dilution provision for certain PCB remediation waste.\43\ Such 
remediation waste is managed for disposal based on the concentration of 
the PCBs found in the affected media at the time the waste is 
discovered as opposed to the concentration of PCBs in the material that 
was originally spilled, released, or otherwise disposed of at the site. 
TSCA does not allow further iterative stages of successive dilution 
such as by intentionally or fortuitously excavating soils affected by a 
release from a regulated source into stockpiles with subsequent 
characterization for disposal testing. The Agency clarified this 
position by developing specific questions and answers related to as-
found concentrations in EPA's PCB Q&A Manual available on the EPA PCB 
website at https://www.epa.gov/pcbs/polychlorinated-biphenyl-pcb-question-and-answer-manual-and-response-comment-documents. ``As-found 
concentration'' is used in the PCB regulations particularly in 
reference to PCB remediation waste. See Sec. Sec.  761.50(b) and 
761.61.

9. Clarify Sec.  761.61(a) Cleanups Must Comply With All Applicable 
Requirements
Provisions in the Final Rule
    EPA is finalizing the changes to Sec.  761.61(a)(3)(ii) as 
proposed. EPA is removing the phrase ``assume that it is complete and 
acceptable'' from Sec.  761.61(a)(3)(ii) and adding text to that 
provision clarifying that the subsequent cleanup and disposal must 
comply with all applicable requirements in Sec.  761.61(a)(4) through 
(9). See Sec.  761.61(a)(3)(ii). EPA is not making any other changes to 
Sec.  761.61(a)(3)(ii). EPA is finalizing the changes to Sec.  
761.61(a)(3)(ii) to ensure the notification that responsible parties 
submit under Sec.  761.61(a) complies with all requirements of Sec.  
761.61(a)(3)(i) and the subsequent cleanup and disposal complies with 
all applicable requirements in Sec.  761.61(a)(4) through (9). The 
person submitting the notification is responsible for verifying its 
completeness and accuracy.
    The changes to 761.61(a)(3)(ii) do not impact the responsible 
party's ability to proceed with the cleanup if the Agency does not 
respond within 30 days. However, if upon review of the notification, 
EPA determines that the notification does not contain all information 
required by

[[Page 59679]]

Sec.  761.61(a)(3)(i), sufficient to ensure compliance with Sec.  
761.61(a)(4) through (a)(9) at the site, the Agency may require the 
submission of additional information. Furthermore, regardless of the 
content of the notification, the cleanup and disposal must meet all 
requirements of Sec.  761.61(a)(4) through (9). If the responsible 
party has reason to believe their implementation of Sec.  761.61(a) may 
not satisfy the regulatory requirements, it would be in their best 
interest, from a compliance assurance perspective, to contact the 
appropriate EPA Regional PCB Coordinator before the end of the 30-day 
period, or at least before commencing the cleanup and disposal 
activities. EPA also encourages responsible parties to contact the 
appropriate EPA Regional PCB Coordinator to discuss the notification 
and cleanup plan before submitting it to EPA. See the EPA PCB website 
for a list of the EPA Regional PCB Coordinators at www.epa.gov/pcbs/program-contacts. In addition, PCB cleanup guidance (e.g., PCB Facility 
Approval Streamlining Toolbox) is available on the EPA PCB website at 
https://www.epa.gov/pcbs.
Discussion of the Public Comments
    EPA proposed to remove the phrase ``assume that it is complete and 
acceptable'' from 761.61(a)(3)(ii) and to add language clarifying that 
the subsequent cleanup and disposal must comply with all applicable 
requirements in Sec.  761.61(a)(4) through (9). Two commenters 
supported the proposed clarification that responsible parties must 
ensure that notifications submitted to EPA under Sec.  761.61(a) and 
the subsequent cleanup and disposal of PCB remediation waste under 
Sec.  761.61(a) comply with all applicable requirements. Several 
commenters opposed the proposed deletion of the phrase ``assume that it 
is complete and acceptable'' from Sec.  761.61(a)(3)(ii). Commenters 
proposed that EPA extend the 30-day timeframe for EPA to respond to a 
notification to 60 days, expressed concerns with EPA identifying issues 
after the responsible party begins the cleanup, and voiced concerns 
with delayed cleanup implementation and increased cleanup costs. The 
30-day timeframe for EPA to respond to a notification is intended to 
prevent compromising the expeditious nature of Sec.  761.61(a) self-
implementing cleanups. The responsible party has the option to contact 
EPA before submitting the notification to ensure they are preparing a 
notification that meets all the requirements of Sec.  761.61(a). In 
addition, the responsible party may contact EPA during the 30-day 
period to go over the submitted notification with EPA. If EPA needs 
additional information, EPA expects to request it within those 30 days.
    EPA finds that no changes are necessary based on public comments, 
as addressed above. Therefore, EPA is finalizing changes to Sec.  
761.61(a)(3)(ii) as proposed.
10. Harmonize PCB Concentration Language Regarding Cap Material
    The Agency is finalizing the proposal to correct a PCB remediation 
waste cap requirement to provide consistency with the rest of the PCB 
regulations. EPA received one public comment in support of this 
provision.
    Previously, Sec.  761.61(a)(7) required that ``a cap shall not be 
contaminated at a level >=1 ppm PCB per Aroclor\TM\ (or equivalent) or 
per congener.'' EPA is deleting ``per Aroclor\TM\ (or equivalent) or 
per congener'' to make this requirement consistent with the rest of the 
PCB regulations. A PCB congener is a single PCB molecular structure, 
with (a) chlorine atom(s) attached to the benzene rings in different 
configurations. Aroclors are mixtures of these PCB congeners that were 
manufactured between 1929 and 1979. There are 209 congeners and sixteen 
known Aroclors.44 45
---------------------------------------------------------------------------

    \44\ https://www.epa.gov/pcbs/table-polychlorinated-biphenyl-pcb-congeners.
    \45\ https://www.epa.gov/pcbs/table-aroclors.
---------------------------------------------------------------------------

    The rest of the PCB regulations only specify requirements or 
restrictions based on PCB concentrations, rather than PCB congener 
concentrations or PCB Aroclor concentrations. The PCB regulations at 
Sec.  761.1(b)(2) state ``Unless otherwise provided, PCBs are 
quantified based on the formulation of PCBs present in the material 
analyzed,'' which means that when PCBs are present as Aroclors (e.g., 
in PCB transformer oil), they may be measured and reported as Aroclors. 
When PCBs are present as congeners that do not match an Aroclor pattern 
(e.g., in weathered environmental samples), they should be measured as 
congeners and reported as a sum of those congeners. Furthermore, there 
is no technical or risk-based reason why PCB remediation waste cap 
requirements should differ from other sections of the PCB regulations. 
As a result, the new language simply requires that ``a cap shall not be 
contaminated at a level >=1 ppm PCBs.'' This change is consistent with 
how PCB concentrations are described in the rest of the TSCA PCB 
regulations. See Sec.  761.61(a)(7).
11. Clarify Applicability of Deed Restrictions
    The Agency is finalizing the proposed clarifications to the 
requirements for deed restrictions associated with PCB remediation 
waste being left on-site under a self-implementing cleanup and disposal 
activity under Sec.  761.61(a). EPA received one public comment in 
support of this provision.
    The self-implementing cleanup and disposal option for PCB 
remediation waste provides for varying cleanup levels based on the 
occupancy level and the presence of a fence or cap. When cleanup levels 
are based upon low occupancy of the cleanup area or the existence of a 
fence or cap (either in high or low occupancy areas), deed restrictions 
are required. See Sec.  761.61(a)(8). EPA's 2005 PCB Site 
Revitalization Guidance confirms that Sec.  761.61(a)(8) requires a 
deed restriction for all cleanups requiring caps or fences, and all 
cleanups based on low-occupancy uses.\46\ However, portions of the 
regulatory text previously suggested that the deed restriction must 
reference low-occupancy status and the existence of a cap or fence in 
every case, even though some sites with low occupancy cleanups will not 
have caps or fences and some sites with caps or fences will not be low-
occupancy. To remedy any potential for confusion, EPA is finalizing 
several minor edits to Sec.  761.61(a)(8) to clarify that deed 
restrictions apply to any area with a cap, a fence, or a low occupancy 
designation.

13. https://www.epa.gov/sites/production/files/2015-08/documents/pcb-guid3-06.pdf.
---------------------------------------------------------------------------

    In addition, EPA is clarifying in Sec.  761.61(a)(8)(i)(A) that the 
deed restriction should designate the portion of a property that is 
subject to the deed restriction, when applicable. The deed restriction 
should reference the location of the cap, fence, or low occupancy 
portion in a format that makes sense for the site, for example, 
latitude/longitude coordinates, street address, or annotated areal 
image. EPA intends for the December 2012 Institutional Controls 
document to provide guidance on how to effectively plan, implement, 
maintain, and enforce deed restrictions required under Sec.  
761.61(a)(8).\47\

12. Include Alternate Extraction and Analysis Under Sec.  761.61(c)--
PCB Remediation Waste
    The Agency is finalizing its proposal to clarify that, under a 
Sec.  761.61(c) risk-based approval, a responsible party can be 
permitted to perform extraction or analysis of PCB remediation waste in 
a manner other than prescribed in Sec.  761.61(a) or (b), including in 
lieu of a Subpart Q comparison study. Prior to this change, EPA's 
practice has been to allow responsible parties to request the use of a 
different extraction or analysis method for PCB remediation waste under 
Sec.  761.61(c), as they are considered part of sampling requirements. 
This change clarifies that responsible parties have this option, by 
adding extraction and analysis to the list of modifiable requirements 
under a Sec.  761.61(c) risk-based approval. EPA received two public 
comments in support of this provision.
13. Include Alternate Extraction and Analysis Under Sec.  761.62(c)--
PCB Bulk Product Waste
    The Agency is finalizing its proposal to clarify that, under a 
Sec.  761.62(c) risk-based approval, a responsible party can be 
permitted to perform extraction or analysis of PCB bulk product waste 
in a manner other than prescribed in Sec.  761.62(a) or (b). Prior to 
this change, EPA's practice has been to allow responsible parties to 
request the use of a different extraction or analysis method for PCB 
bulk product waste under Sec.  761.62(c), as they are considered part 
of sampling requirements. This change clarifies that responsible 
parties have this option, by adding extraction and analysis to the list 
of modifiable requirements under a Sec.  761.62(c) risk-based approval. 
EPA received no public comments on this provision.
14. Include Alternate Extraction and Analysis Under Sec.  761.79(h)--
Decontaminated Material
    The Agency is clarifying that, under a Sec.  761.79(h) approval, a 
responsible party can be permitted to perform extraction or analysis of 
decontaminated material in a manner other than prescribed in Sec.  
761.79(f). Prior to this change, EPA's practice has been to allow 
responsible parties to request to modify or replace the use of an 
extraction or analysis method for decontaminated material under Sec.  
761.79(h), as they are considered part of sampling procedure. This 
change clarifies that responsible parties have this option, by adding 
extraction and analysis to the list of modifiable requirements under a 
Sec.  761.79(h) approval. EPA received no public comments on this 
provision.
15. Clarify Sampling Procedure for Non-Porous Surfaces
    The Agency is finalizing its proposal to correct an inconsistency 
with respect to non-porous surfaces in the site characterization 
requirements for self-implementing cleanups of PCB remediation waste 
under Sec.  761.61(a). The site characterization requirements in Sec.  
761.61(a)(2) provide that site characterization may be conducted using 
procedures included in 40 CFR part 761, subpart N. The method found in 
Subpart N for sampling non-porous surfaces specifies that the sampling 
area shall be divided into ``square portions approximately 2 meters on 
each side'' and to ``[f]ollow the procedures in Sec.  761.302(a).'' See 
Sec.  761.267(a). However, Sec.  761.302(a), which is the section of 
the PCB regulations pertaining to post-cleanup sampling of non-porous 
surfaces, specifies dividing the surface into 1-meter square portions 
instead of 2-meter square portions. EPA is amending Sec.  761.267 by 
adding the following italicized language to this provision, ``Follow 
the procedures in Sec.  761.302(a), with the exception of the sampling 
grid size,'' to correct the inconsistency. This change reflects the way 
in which EPA has already been addressing the inconsistency. EPA 
received two public comments in support of this provision.
16. Add Unit to Concentration in Sec.  761.1(b)(3)
    The Agency is finalizing its proposal to modify text in Sec.  
761.1(b)(3) to read ``PCB concentrations of >10 [micro]g/100 cm\2\.'' 
Previously, Sec.  761.1(b)(3) listed a concentration with only partial 
units of reference, ``PCB concentrations of >10/100 cm\2\,'' which was 
meaningless as written. It is clear from context that the text should 
have read ``PCB concentrations of >10 [micro]g/100 cm\2\,'' which is 
how surface concentrations otherwise appear throughout the PCB 
regulations, including, for example in Sec.  761.79(b). EPA received 
one public comment in support of this revision. EPA also proposed to 
harmonize the ``greater/less than'' and ``greater/less than or equal 
to'' symbols in this section but is not finalizing that change, as 
doing so might create some inconsistency with the definitions section 
of the PCB regulations.
17. Update References to ASTM Methods
    The regulations at Sec.  761.19 incorporate by reference several 
ASTM test method standards that have since been updated. EPA is adding 
three updated methods, removing a withdrawn method, updating a method 
which was withdrawn and replaced with a newer method, and updating 
references to two methods which are currently unavailable on ASTM's 
website. These ASTM standards reflect the current consensus of ASTM 
members. EPA is making the following changes:
    ASTM D93-09, Standard Test Methods for Flash Point by Pensky-
Martens Closed Tester, was approved by ASTM in 2009 and added to the 
PCB regulations in 2012 at Sec. Sec.  761.71(b)(2)(vi) and 
761.75(b)(8)(iii).\48\ EPA is adding as an alternative ASTM D8175-18, 
Test Method for Finite Flash Point Determination of Liquid Wastes by 
Pensky-Martens Closed Cup Tester.
---------------------------------------------------------------------------

    \48\ 77 FR 2463, Jan. 18, 2012.
---------------------------------------------------------------------------

    ASTM D3278-89, Standard Test Methods for Flash Point of Liquids by 
Setaflash Closed-Cup Apparatus, was approved by ASTM in 1989 and added 
to the PCB regulations in 1992 at Sec.  761.75(b)(8)(iii).\49\ EPA is 
replacing the updated version, ASTM D3278-96 (Reapproved 2011), 
Standard Test Methods for Flash Point of Liquids by Small Scale Closed-
Cup Apparatus, and adding ASTM D8174-18, Test Method for Finite Flash 
Point Determination of Liquid Wastes by Small Scale Closed Cup Tester.
---------------------------------------------------------------------------

    \49\ 57 FR 13323, Apr. 16, 1992.
---------------------------------------------------------------------------

    EPA is removing ASTM D2784-89, Standard Test Method for Sulfur in 
Liquified Petroleum Gases (Oxy-hydrogen Burner or Lamp) from Sec.  
761.19 and Sec.  761.71(a)(2)(vi). This test method was withdrawn in 
June 2016 because it is archaic and not used in the industry.\50\
---------------------------------------------------------------------------

    \50\ https://compass.astm.org/Standards/WITHDRAWN/D2784.htm.
---------------------------------------------------------------------------

    EPA is removing ASTM D3178-84, Standard Test Methods for Carbon and 
Hydrogen in the Analysis Sample of Coke and Coal, replacing it with 
D5373-16, Standard Test Methods for Determination of Carbon, Hydrogen 
and Nitrogen in Analysis Samples of Coal and Carbon in Analysis Samples 
of Coal and Coke, in Sec. Sec.  761.19 and 761.71(b)(2)(vi). ASTM 
D3178-84 was replaced in June 2007 because there was no reproducibility 
statement for D3178.\51\
---------------------------------------------------------------------------

    \51\ https://compass.astm.org/Standards/WITHDRAWN/D3178.htm.
---------------------------------------------------------------------------

    EPA is replacing ASTM D482-87, Standard Test Method for Ash from 
Petroleum Products, with ASTM D482-13, Standard Test Method for Ash 
from Petroleum Products, in Sec.  761.71(a)(2)(vi). EPA is also 
replacing

[[Page 59681]]

ASTM D3278-89, Standard Test Methods for Flash Point of Liquids by 
Setaflash Closed-Cup Apparatus, with ASTM D3278-96(R2011), Standard 
Test Methods for Flash Point of Liquids by Small Scale Closed-Cup 
Apparatus, in Sec.  761.75(b)(8)(iii) (see above). ASTM began building 
its electronic library of standards in the 1990s, so the 1987 version 
of ASTM D482 and the 1989 version of ASTM D3278 are no longer available 
from the ASTM website. Therefore, the Agency is updating ASTM D482-87 
and ASTM D3278-89 to list the most recent versions of the methods.
    EPA has found that most of the entities that would have to comply 
with these standards are already familiar with them, since it would be 
difficult to be in the business of testing for PCBs without being 
familiar with these industry consensus standards. The standards are all 
readily available electronically or in print and are relatively 
inexpensive. See Sec.  761.19. EPA received one public comment in 
support of this provision.
18. Require a Wipe Sample Under Sec.  761.30(i)(4)
    Section 761.30(i)(4), which governs characterization of PCB 
contamination in natural gas pipe or natural gas pipeline systems, 
previously read, in part, ``if no liquids are present, they must use 
standard wipe samples in accordance with Subpart M of this part.'' This 
language might be read to mean that all natural gas pipe or natural gas 
pipeline systems must be characterized using standard wipe samples if 
no liquids are present. However, this text was meant to convey that if 
any person chooses to characterize natural gas pipe or natural gas 
pipeline systems that do not contain liquids, then they must do so 
using wipe samples.\52\ Therefore, EPA is finalizing its proposal to 
replace the text with: ``if no liquids are present and they decide, in 
their discretion, to characterize PCB contamination, the person must 
use standard wipe samples in accordance with Subpart M of this part.'' 
See Sec.  761.30(i)(4). EPA received three public comments in support 
of this provision.
---------------------------------------------------------------------------

    \52\ See PCB Q&A Manual. June 2014. Pg. 23 (``Under the use 
authorization provisions at Sec.  761.30(i), if a pipeline system 
once contained liquids at 50 ppm or greater but is now relatively 
dry (i.e., there are no liquids available to test at existing 
condensate collection points), then the owner/operator of the 
pipeline system has no further sampling and analysis to do until 
such time as liquids appear. EPA did not intend to require wipe 
sampling for characterizing natural gas pipeline systems in use. . . 
.''). https://www.epa.gov/sites/production/files/2015-08/documents/qacombined.pdf.
---------------------------------------------------------------------------

19. High Efficiency Boilers Approval Application Requirements
    EPA is finalizing its proposal to correct an editorial error in 
Sec.  761.71. This section describes the required operating parameters 
for high efficiency boilers that dispose of PCB waste. The requirements 
for high efficiency boilers are divided into two sections, a section 
for burning PCB-contaminated mineral oil dielectric fluid at Sec.  
761.71(a) and a section for burning any other PCB-contaminated fluids 
at Sec.  761.71(b). Mineral oil dielectric fluid is an insulating fluid 
used in electrical equipment such as transformers. Other PCB-
contaminated fluids might include used oil, contaminated water, and 
hydraulic fluid. Section 761.71(b) regulates high efficiency boilers 
that burn PCB liquids other than mineral oil dielectric fluid, so EPA 
is amending Sec.  761.71(b)(2)(iv) to correct an error by replacing the 
phrase ``mineral oil dielectric fluid'' with ``PCB liquids.'' See Sec.  
761.71(b)(2)(iv). EPA received one public comment in support of this 
provision.
20. Mailing Address for Annual Reports
    The owner or operator of any PCB disposal facility or commercial 
storage facility submits an annual report to the EPA Regional 
Administrator for the region in which the facility is located, pursuant 
to Sec.  761.180(b)(3). EPA is finalizing its proposal to change the 
recipient of the annual reports from the Regional Administrator to the 
Director of the Office of Resource Conservation and Recovery, which is 
the office in EPA Headquarters that manages the PCB cleanup and 
disposal program. An analogous change is also being made in Sec.  761.3 
under the definition of annual report. This change will reduce the 
administrative burden on the Agency of compiling the data in the annual 
reports, which is used to inform Agency actions. The address for 
submission will be displayed prominently on the mandatory form. See 
Sec. Sec.  761.3 and 761.180(b)(3). EPA received one public comment in 
support of this provision.
21. Update Address for Submission of EPA Form 7710-53
    EPA is finalizing its proposal to remove the address for submission 
of EPA form 7710-53, ``Notification of PCB Activity,'' from the 
regulations. This change will allow EPA to more easily update the 
mailing address in the future without undertaking a regulatory change. 
The mailing address will continue to appear on the form itself and can 
be updated through the Information Collection Request (ICR) process. 
This change will expedite future address changes and thus streamline 
the distribution of mail and reduce the processing time for these 
forms. See Sec. Sec.  761.205(a)(3) and 761.205(d). EPA received one 
public comment in support of this provision.
22. Add Field for Facility Email Address and EPA PCB Email Address to 
EPA Form 7710-53
    EPA is finalizing its proposal to require that an email address 
must be submitted on the EPA form 7710-53, ``Notification of PCB 
Activity.'' Additionally, EPA is adding the EPA PCB email address 
([email protected]) to the notification form to facilitate any questions 
from members of the public. These changes will improve communication 
and reduce the processing time for these forms. Any Notification of PCB 
Activity form submitted prior to the effective date of this rulemaking 
will not be required to be resubmitted, unless the facility would like 
to add or update information (including the email address). See 
Sec. Sec.  761.205(a)(3) and 761.205(d).
    EPA received one public comment in support of this provision and 
one public comment which questioned if EPA form 7710-53 will need to be 
resubmitted to provide an email address. The form will not be required 
to be resubmitted to provide an email address, and only needs to be 
resubmitted if something changes at the site. While not mandating 
resubmission, the Agency does encourage sites to resubmit the form to 
supply an email address.
23. Sample Site Selection Instructions for Pipelines
    Subpart M provides a number of steps that must be followed when 
selecting the locations for sampling to characterize natural gas 
pipeline. EPA found that, due to rounding errors, the instructions for 
a length of pipe greater than seven segments but shorter than three 
miles in length were incorrect. EPA is finalizing its proposal to 
modify the instructions and the example given in Sec.  
761.247(b)(2)(ii)(B) to clarify where each sample must be taken along 
pipes of this length. This change is a technical correction and does 
not influence the number of samples taken or the burden on the owner or 
operator of the pipe. See Sec.  761.247(b)(2)(ii)(B). EPA received one 
public comment in support of this provision.
24. Remove Reference to Method 3500B
    SW-846 is organized such that several similar methods are grouped 
together in

[[Page 59682]]

a series. The 3500 series contains extraction procedures used for the 
preparation of samples for analysis of organic parameters. These 
techniques include Liquid-Liquid Extraction, Solid-Phase Extraction, 
Soxhlet Extraction, and Supercritical Fluid Extraction, among others. 
Method 3500B (recently updated to Method 3500C) is not a detailed 
method where step-by-step instructions are discussed.53 54 
Rather, Method 3500B simply provides general guidance for all the 
methods within its series (i.e., the 3500 series), including the 
extraction methods being added as part of this rulemaking. Also, Method 
3500B or 3500C is already referenced in every 3500 series method EPA is 
adding to the PCB regulations. Therefore, EPA feels that it is 
unnecessary to reference Method 3500B in the PCB regulations directly 
and is removing the reference from the PCB regulations. The removal of 
Method 3500B from the regulations does not influence any of the 3500 
series methods currently in or being added to the PCB regulations. The 
PCB regulatory sections affected are Sec. Sec.  
761.61(a)(5)(i)(B)(2)(iv), 761.253, 761.272, 761.292, 761.358, and 
761.395. EPA received one public comment in support of this provision.

25. Correct References to SW-846
    The official title of the EPA publication known as SW-846 was 
updated from ``Test Methods for Evaluating Solid Waste'' to ``Test 
Methods for Evaluating Solid Waste: Physical/Chemical Methods.'' There 
are several references to this publication throughout the PCB 
regulations. EPA is finalizing its proposal to update the definition of 
SW-846 in Sec.  761.3 with the current official title and to refer to 
it as ``SW-846'' throughout the PCB regulations, for readability. See 
Sec. Sec.  761.3, 761.60(g)(1)(iii), 761.61(a)(5)(i)(B)(2)(iv), 
761.253(a), 761.272, 761.292, 761.358, 761.395(b)(1). EPA received one 
public comment in support of this provision.
26. Correct References to EPA's PCB Website
    Throughout the PCB regulations, there are several references to 
EPA's PCB website. In 2015, as part of a redesign, the URL for the EPA 
PCB web page changed from https://www.epa.gov/pcb to https://www.epa.gov/pcbs. EPA is finalizing its proposal to update those 
references throughout the PCB regulations. See Sec. Sec.  761.130(e), 
761.205(a)(3), 761.243(a), 761.386(e). EPA received one public comment 
in support of this provision, and one comment that suggested removing 
weblinks completely from the PCB regulations to avoid the need for 
future updates. EPA finds, however, that periodic maintenance of web 
links in the regulations is outweighed by the benefits of providing a 
direct link in the PCB regulations to applicable information for the 
regulated community.
27. Change ``He'' to ``They''
    The PCB regulations previously referred to generic individuals such 
as the Regional Administrator or facility owners as ``he,'' ``his,'' 
``he/she,'' or ``he or she.'' EPA is finalizing its proposal to replace 
all such references with the gender neutral ``they'' and ``their.'' See 
Sec. Sec.  761.3, 761.20(e)(3)(ii)(B), 761.20(e)(4)(i), 
761.20(e)(4)(ii), 761.50(b)(3)(i)(A), 761.60(b)(2)(v)(C), 
761.61(a)(8)(i)(B), 761.65(g), 761.65(h), 761.70(d)(4)(i), 
761.75(c)(3)(i), 761.75(c)(4), 761.77(a)(1)(ii)(B), 761.77(a)(2), 
761.77(b), 761.120(b)(2), 761.125(c)(3)(iii), 761.125(c)(4)(iv), 
761.180(b)(4), 761.207(c), 761.212(a), 761.213(a)(4), 761.213(b), 
761.214(a), 761.216(a), 761.217(a)(2)(ii). EPA received one public 
comment in support of this provision.
28. Change ``On Site'' to ``On-Site''
    The term ``on site'' is included in the definitions at Sec.  761.3, 
but the PCB regulations previously used the term ``on-site'' 
throughout. EPA is finalizing its proposal to modify Sec.  761.3 to 
read ``on-site'' to improve the readability of the PCB regulations. See 
Sec.  761.3. EPA received no public comments on this provision.
29. Correct Reference to Methods for Standard Wipe Test Samples
    Section 761.314 ``Chemical analysis of standard wipe test samples'' 
previously instructed the reader to ``perform the chemical analysis of 
standard wipe test samples in accordance with Sec.  761.272.'' While 
Sec.  761.272 does contain the allowable methods for wipe test samples, 
it also lists several other methods that would not be appropriate for 
wipe test samples. This reference has been corrected to Sec.  761.253, 
which is specific to wipe samples. EPA received one public comment in 
support of this provision.
30. Incorporation by Reference
    The Agency is incorporating by reference SW-846 Test Methods 3541, 
3545A, 3546, 3510C, 3520C, 3535A, 3550C, and 8082A into 40 CFR part 761 
under Sec. Sec.  761.60, 761.61, 761.253, 761.272, 761.292, 761.358, 
and 761.395. Finally, the Agency is incorporating by reference ASTM 
standards D482-13, D3278-96(R2011), D4059-00, D5373-16, D8174-18, and 
D8175-18 into 40 CFR part 761 under Sec. Sec.  761.60, 761.71, and 
761.75. (See section II.B of this preamble for summaries of the IBR 
material.)
    The following standards appear in the amendatory text of this 
document and have already been approved for the locations in which they 
appear: ASTM D93-09, D129-64(R1968), D240-87, D524-88, D808-87, D923-
86, D923-89, D1266-87, D1796-83, D2158-89, D2709-88, and E258-67.
    The SW-846 Test Methods being incorporated by reference are 
published in the test methods compendium known as, ``Test Methods for 
Evaluating Solid Waste, Physical/Chemical Methods,'' EPA Publication 
SW-846, Third Edition, available at https://www.epa.gov/hw-sw846. ASTM 
materials may be obtained from ASTM International, 100 Barr Harbor Dr., 
P.O. Box C700, West Conshohocken, PA 19428-2959, or by calling (877) 
909-ASTM, or at www.astm.org. EPA methods being incorporated by 
reference are also included in the docket. EPA received one public 
comment in support of this provision.

IV. Economic Impacts of the Final Rulemaking

    One focus of the final rule is expanding the allowable PCB 
extraction methods, which impacts testing laboratories (NAICS code 
541380) that currently perform PCB extractions under TSCA. Based on 
method-specific certifications and communication with laboratory 
personnel, EPA estimates that approximately 19 laboratories are 
impacted by the rule. Further, EPA estimates that these 19 laboratories 
perform approximately 65,000 relevant extractions each year. Some 
laboratories may experience a one-time cost of purchasing equipment 
used to perform one of the extraction methods. However, the decreases 
in solvent and labor hours required to perform the extraction methods 
are expected to result in net annual cost savings of approximately $4.7 
million, annualized at a discount rate of seven percent. The cost 
savings at a discount rate of three percent is $6.6 million.

[[Page 59683]]

    The revisions to Sec.  761.61(b) may impact any facility performing 
a PCB site remediation under Sec.  761.61(b). No data are available on 
the exact number of Sec.  761.61(b) remediations performed annually, 
but EPA estimates that there will be between 430 and 460 relevant 
remediations per year, based on an analysis of 2018 and 2019 hazardous 
waste manifests. Certain aspects of this provision increase burden on 
the regulated community through certain requirements (e.g., 
recordkeeping, notification, sampling). However, EPA is also allowing 
for disposal of relevant waste at RCRA Subtitle C landfills under Sec.  
761.61(b), in addition to the existing disposal options (e.g., TSCA 
landfills, TSCA incinerators), which will decrease transportation and 
disposal costs related to non-hazardous, non-liquid PCB remediation 
waste for the regulated community. Overall, the revisions to Sec.  
761.61(b) are expected to result in net annual cost savings between 
$9.8 million and $11.5 million, annualized at a discount rate of seven 
percent and three percent, respectively.
    Disallowing PCB bulk product waste to be used as roadbed material 
has the potential to create a slight increase in costs for the 
regulated community. Facilities that would have used PCB bulk product 
waste on-site as roadbed material under asphalt now have to pay to 
transport the waste to a municipal solid waste landfill and pay the 
associated tipping fee for disposal. EPA believes that the practice of 
using PCB bulk product waste as roadbed is exceedingly rare. However, 
in an effort to incorporate all potential impacts of the final rule, 
the Economic Assessment modeled a single party using PCB bulk product 
waste as roadbed per year. EPA estimates that the cost increase for the 
regulated community will be between $740 and $6,630 per year.
    EPA anticipates that the added flexibilities for emergency 
situations will result in cost savings for the regulated community. EPA 
estimates that there will be between 12 and 60 emergencies each year 
where the regulated community may use the flexibilities. A lack of data 
prevents an overall quantitative estimate of the cost savings from this 
provision. However, impacted parties are expected to save money and 
time by avoiding delays associated with searches for the source of the 
spill during an emergency situation where the search is likely to be 
time-consuming and unsuccessful, and by being able to manage waste 
under the less burdensome procedures of Sec.  761.125(b), rather than 
Sec.  761.125(c). The regulated community is also expected to see a 
decrease in sampling and testing expenditures.
    The change to harmonize the general disposal requirements for PCB 
remediation waste is in line with current EPA policy, guidance and 
practice. Therefore, EPA estimates that this change will not have any 
economic impact.
    The Economic Assessment for the final rule is constrained by the 
lack of relevant data, largely because the final rule makes changes to 
provisions that are self-implementing and/or require no EPA 
notification. EPA has quantified costs and cost savings when possible. 
When quantification has not been possible, EPA has analyzed the costs 
and cost savings qualitatively. The Economic Assessment associated with 
the final rule can be referenced for a greater level of detail related 
to the costs and benefits of the revisions.

    Respondent's obligation to respond: The recordkeeping and 
notification requirements are required for parties performing relevant 
activities (e.g., using Sec.  761.66 waivers in emergency situations). 
These requirements are described in detail in the ICR Supporting 
Statement.
    Estimated number of respondents: 1,085.
    Frequency of response: On occasion/as necessary.
    Total estimated burden: 8,276 hours.
    Total estimated cost: $1,051,643.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under RFA, 5 U.S.C. 
601 et seq. In making this determination, the impact of concern is any 
significant adverse economic impact on small entities. An agency may 
certify that a rule will not have a significant economic impact on a 
substantial number of small entities if the rule relieves burden or has 
no net burden on the small entities subject to the rule. These changes 
would reduce the impacts on all small entities subject to the rule, so 
there are no significant impacts to any small entities. We have 
therefore concluded that this action will relieve regulatory burden for 
all directly regulated small entities. Details of this analysis are 
presented in the Economic Assessment, which is in the public docket for 
this action.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more as described in UMRA, 2 U.S.C. 1531-1538, and does not 
significantly or uniquely affect small governments. EPA estimates that 
the final rule would result in net annual cost savings of between $14.4 
and $16.2 million, assuming a seven percent discount rate ($16.3 to 
$18.1 at a three percent discount rate). As a result, EPA expects that 
the rule would not result in annual expenditures exceeding $100 million 
annually and therefore would not be subject to requirements of section 
202 of UMRA as listed above.

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the states, on the relationship between 
the national government and the states, or on the distribution of power 
and

[[Page 59684]]

responsibilities among the various levels of government.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have Tribal implications as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000) because the 
action is not expected to result in any adverse environmental or human 
health impacts on Tribal entities. In addition, the action is expected 
to result in a cost savings and is not expected to result in any 
adverse financial impacts on Tribal entities. Thus, Executive Order 
13175 does not apply to this rule. Consistent with the EPA Policy on 
Consultation and Coordination with Indian Tribes, the EPA prepared a 
Tribal consultation and coordination plan and sent a letter to the 
tribes on July 13, 2021, inviting consultation. EPA did not receive any 
comments from tribes.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 (62 FR. 19885, 
April 23, 1997) because it is not an economically significant 
regulatory action as defined by Executive Order 12866. In addition, 
because the rule would not increase risk related to exposure to 
hazardous materials, the Agency does not believe the environmental 
health or safety risks addressed by this action present a 
disproportionate risk to children.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution or Use

    This action is not a ``significant energy action'' under Executive 
Order 13211, ``Actions Concerning Regulations that Affect Energy 
Supply, Distribution, or Use'' (May 18, 2001) because it is not likely 
to have a significant adverse effect on the supply, distribution or use 
of energy. The proposed rule would not directly regulate energy 
production or consumption and is expected to result in net cost 
savings.

I. National Technology Transfer and Advancement Act (NTTAA)

    This action involves technical standards. In this rulemaking, the 
EPA incorporates voluntary consensus standards (VCSs) developed by both 
ASTM and the Agency into the rulemaking, consistent with the National 
Technology Transfer and Advancement Act (NTTAA). These VCSs support PCB 
cleanups as well sampling activities including the extraction and 
analysis of PCBs. For more details on the technical standards that EPA 
is using in this rulemaking, please see Section III.G.--Incorporation 
by Reference.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, February 16, 1994) directs 
Federal agencies, to the greatest extent practicable and permitted by 
law, to make environmental justice part of their mission by identifying 
and addressing, as appropriate, disproportionately high and adverse 
human health or environmental effects of their programs, policies, and 
activities on minority populations (people of color and/or indigenous 
peoples) and low-income populations.
    The EPA believes that the human health or environmental conditions 
that exist prior to this action result in or have the potential to 
result in disproportionate and adverse human health or environmental 
effects on people of color, low-income populations and/or indigenous 
peoples. Examples of these potential disproportionate effects include 
PCB contamination occuring more frequently in these communities, as 
well as disproportionate effects from emergency situations and climate 
change.
    The EPA believes that this action is likely to reduce existing 
disproportionate and adverse effects on people of color, low-income 
populations and/or indigenous peoples. Generally, the final rule will 
modernize the PCB regulations, making it easier and more affordable to 
clean up contaminated sites, while continuing to ensure that the 
requirements remain protective of health and the environment. 
Underserved, disadvantaged, and overburdened communities are expected 
to benefit from quicker, more cost-effective, compliant cleanups under 
the final rule. For example, adding explicit cleanup provisions under 
Sec.  761.61(b), including the requirements to notify EPA and follow 
specific sampling protocols, will provide additional assurance that 
sites are properly remediated and enhance compliance and enforcement. 
Furthermore, the increased flexibility for emergency situations 
provided under Sec.  761.66 will allow the Agency to work 
collaboratively with responsible parties to more quickly respond to 
releases of PCBs caused by natural disasters and other emergency 
situations, which can disproportionately impact such communities.

K. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule 
report to each House of the Congress and to the Comptroller General of 
the United States. This action is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

* * * * *
    Administrator means the Administrator of the Environmental 
Protection Agency, or any employee of the Agency to whom the 
Administrator may either herein or by order delegate their authority to 
carry out their functions, or any person who shall by operation of law 
be authorized to carry out such functions.
* * * * *
    Annual report means the completed EPA Form 6200-025 submitted each 
year by each disposer and commercial storer of PCB waste to the 
Director, Office of Resource Conservation and Recovery. The annual

* * * * *
    As-found concentration means the concentration measured in samples 
collected in-situ (i.e., prior to being moved or disturbed for cleanup 
and/or disposal) from environmental media or material, unless otherwise 
specifically provided. For example, media must not be disturbed, nor 
may they be diluted (e.g., excavated, placed on a pile, and sampled 
after such placement), before characterization sampling is conducted. 
Sampling media in piles and existing accumulations would be considered 
``as-found'' if the media were already in piles when the site was first 
visited by the responsible party, such as during the redevelopment of 
abandoned properties with historic PCB contamination. The as-found 
concentration is distinct from the source concentration, which is the 
concentration of the PCBs in the material that was originally spilled, 
released, or otherwise disposed of at the site.
    ASTM means ASTM International, 100 Barr Harbor Drive, West 
Conshohocken, PA 19428-2959.

expected to result in: (1) A declaration by either the President of the 
United States or Governor of the affected State of a natural disaster 
or emergency; or, (2) an incident funded under FEMA via a Stafford Act 
disaster declaration or emergency declaration. Examples of emergency 
situations may include civil emergencies or adverse natural conditions, 
such as hurricanes, earthquakes, or tornados.
* * * * *
    Non-porous surface means a smooth, unpainted solid surface that 
limits penetration of liquid containing PCBs beyond the immediate 
surface. Examples are: smooth uncorroded metal; natural gas pipe with a 
thin porous coating originally applied to inhibit corrosion; smooth 
glass; smooth glazed ceramics; impermeable polished building stone such 
as marble or granite; and medium- and high-density plastics, such as 
polycarbonates and melamines, that do not absorb solvents.
    NTIS means the National Technical Information Service, 5301 Shawnee

    (A) Sites containing these wastes are presumed not to present an 
unreasonable risk of injury to health or the environment from exposure 
to PCBs at the site. However, the EPA Regional Administrator may inform 
the owner or operator of the site that there is reason to believe that 
spills, leaks, or other uncontrolled releases or discharges, such as 
leaching, from the site constitute ongoing disposal that may present an 
unreasonable risk of injury to health or the environment from exposure 
to PCBs at the site, and may require the owner or operator to generate 
data necessary to characterize the risk. If after reviewing any such 
data, the EPA Regional Administrator makes a finding, that an 
unreasonable risk exists, then they may direct the owner or operator of 
the site to dispose of the PCB remediation waste in accordance with 
Sec.  761.61 such that an unreasonable risk of injury no longer exists.

    (ii) For purposes of complying with the marking and disposal 
requirements, representative samples may be taken from either the 
common containers or the individual electrical equipment to determine 
the PCB concentration. Except, that if any PCBs at a concentration of 
500 ppm or greater have been added to the container or equipment then 
the total container contents must be considered as having a PCB 
concentration of 500 ppm or greater for purposes of complying with the 
disposal requirements of this subpart. For purposes of this paragraph, 
representative samples of mineral oil dielectric fluid are either 
samples taken in accordance with ASTM D923-86 or ASTM D923-89 (both 
incorporated by reference, see Sec.  761.19) or samples taken from a 
container that has been thoroughly mixed in a manner such that any PCBs 
in the container are uniformly distributed throughout the liquid in the

Regional Administrator will respond in writing approving of the self-
implementing cleanup, disapproving of the self-implementing cleanup, or 
requiring additional information. If the EPA Regional Administrator 
does not respond within 30 calendar days of receiving the notice, the 
person submitting the notification may proceed with the cleanup 
according to the information the person provided to the EPA Regional 
Administrator. If, upon review of the notification, the EPA Regional 
Administrator determines that the notification does not contain all of 
the information required by paragraph (a)(3)(i) of this section, 
sufficient to ensure compliance with paragraphs (a)(4) through (9) of 
this section at the site, they may require the submission of additional 
information. The cleanup and disposal must comply with all applicable 
requirements of paragraphs (a)(4) through (9) of this section. Once 
cleanup is underway, the person conducting the cleanup must provide any 
proposed changes from the notification to the EPA Regional 
Administrator in writing no less than 14 calendar days prior to the 
proposed implementation of the change. The EPA Regional Administrator 
will determine in their discretion whether to accept the change and

cleanup and disposal of PCB remediation waste, a uniform placement of 
concrete, asphalt, or similar material of minimum thickness spread over 
the area where remediation waste was removed or left in place in order 
to prevent or minimize human exposure, infiltration of water, and 
erosion. Any person designing and constructing a cap must do so in 
accordance with Sec.  264.310(a) of this chapter, and ensure that it 
complies with the permeability, sieve, liquid limit, and plasticity 
index parameters in Sec. Sec.  761.75(b)(1)(ii) through (v). A cap of 
compacted soil shall have a minimum thickness of 25 cm (10 inches). A 
concrete or asphalt cap shall have a minimum thickness of 15 cm (6 
inches). A cap must be of sufficient strength to maintain its 
effectiveness and integrity during the use of the cap surface which is 
exposed to the environment. A cap shall not be contaminated at a level 
>=1 ppm PCB. Repairs shall begin within 72 hours of discovery for any 
breaches which would impair the integrity of the cap.
    (8) Deed restrictions for caps, fences and low occupancy areas. 
When a cleanup activity conducted under this section includes the use 
of a fence or a cap, the owner of the site must maintain the fence or 
cap, in perpetuity. In addition, whenever a fence, a cap, or the 
procedures and requirements for a low occupancy area, is used, the 
owner of the site must meet the following conditions:
    (i) * * *
    (A) Record, in accordance with State law, a notation on the deed to 
the property, or on some other instrument which is normally examined 
during a title search, that will in perpetuity notify any potential 
purchaser of the property:
    (1) That the land, or the specific portion thereof identified in 
the instrument when only a portion is subject to the instrument, has 
been used

[[Page 59688]]

for PCB remediation waste disposal and, when applicable, that the area 
is restricted to use as a low occupancy area as defined in Sec.  761.3;
    (2) Of the existence of the fence or cap and the requirement to 
maintain the fence or cap, when applicable; and
    (3) The applicable cleanup levels left at the site, including 
inside any fence, under any cap, and/or in a low occupancy area.
    (B) Submit a certification, signed by the owner, that they have 
recorded the notation specified in paragraph (a)(8)(i)(A) of this 
section to the EPA Regional Administrator.
    (ii) The owner of a site being cleaned up under this section may 
remove a fence, cap, or low occupancy designation after conducting 
additional cleanup activities and achieving cleanup levels, specified 
in paragraph (a)(4) of this section, which do not require a fence, cap, 
or low occupancy designation. The owner may remove the notice on the 
deed no earlier than 30 days after achieving the cleanup levels 
specified in this section which do not require a fence, cap, or low 
occupancy designation.

and dispose of PCB remediation waste at a site in full compliance with 
the performance-based cleanup provisions of paragraph (b)(1) of this 
section and disposal provisions of paragraph (b)(2) of this section.

Alternatively, any person may dispose of PCB remediation waste in 
accordance with paragraph (b)(2) of this section, but such disposal 
does not relieve them of cleanup and disposal obligations for any PCBs 
that remain on-site if the provisions of paragraph (b)(1) of this 
section are not complied with.
    (1) Performance-based cleanup of PCB remediation waste--(i) 
Applicability. (A) The performance-based cleanup option may not be used 
to clean up:

surfaces is <=1 ppm PCBs.
    (B) The cleanup levels for liquids are the concentrations specified 
in Sec. Sec.  761.79(b)(1) and (b)(2).
    (C) The cleanup levels for non-porous surfaces are the 
concentrations specified in Sec.  761.79(b)(3).
    (iii) Verification sampling. Verification sampling for bulk PCB 
remediation waste and porous surfaces must be conducted in accordance 
with Subpart O. Verification sampling for non-porous surfaces must be 
conducted in accordance with Subpart P. Verification sampling for 
liquid PCB remediation waste must be conducted in accordance with Sec.  
761.269. When analysis of each sample results in a measurement of PCBs 
less than or equal to the levels specified in paragraph (ii) of this 
section, on-site performance-based cleanup is complete.
    (iv) Recordkeeping. Recordkeeping is required in accordance with 
Sec.  761.125(c)(5).
    (v) Cleanup Completion Notification. Within 30 days of sending the 
final shipment of waste offsite for disposal from a site cleaned up 
under this paragraph, the person in charge of the cleanup or the owner 
of the property where the PCB remediation waste was located shall 
notify, in writing, the EPA Regional Administrator, the Director of the 
State or Tribal environmental protection agency, and the Director of 
the county or local environmental protection agency where the cleanup 
was conducted. EPA may require additional on-site cleanup upon finding 
that the cleanup level(s) in (b)(1)(ii) of this section have not been 
met. Upon review of the cleanup completion notification, EPA may 
request that the responsible party submit additional information 
related to the records required under (b)(1)(iv) of this section to

12. Add Sec.  761.66 to subpart D to read as follows:

Sec.  761.66  Emergency situations.

    This section establishes procedures that may be used for purposes 
of the cleanup and/or disposal of PCB releases caused by an emergency 
situation as defined in Sec.  761.3. This section allows the request of 
a waiver of any of the requirements in Sec. Sec.  761.60, 761.61, 
761.62, or 761.65. Any person conducting activities under these 
emergency provisions is also responsible for determining and complying 
with all other applicable Federal, State, and local laws and 
regulations. This section does not prohibit any person from 
implementing temporary emergency measures to prevent, treat, or contain 
further releases or mitigate migration to the environment of PCBs or 
PCB remediation waste.
    (a) Applicability. This section may only be applied to the cleanup 
and/or disposal of PCB releases caused by an emergency situation as 
defined in Sec.  761.3.
    (b) Waiver Request. Any person intending or planning to sample, 
extract, analyze, clean up, store, and/or dispose of PCBs under this 
section shall submit a waiver request to the Regional Administrator in 
the EPA Region where the sampling, extraction, analysis, cleanup, 
storage, and/or disposal would occur, in writing and/or by email no 
later than seven (7) days after discovery of the release or 
implementation of any temporary emergency measures, as applicable. The 
requestor must also send a copy of the waiver request to the Director 
of the State or Tribal environmental agency where the sampling, 
extraction, analysis, cleanup, storage, and/or disposal would occur. If 
the sampling, extraction, analysis, cleanup, storage, and/or disposal 
activities in the waiver request would be conducted in more than one 
Region, then the waiver request must be submitted, in its entirety, to 
the Regional Administrators for all affected Regions.
    (1) This request shall include:
    (i) The contact information for the person requesting the waiver.
    (ii) Location(s) of the release(s).
    (iii) A description of the emergency situation, including 
information about adverse conditions and the incident(s) that caused 
them.
    (iv) The type(s) of material(s) that are contaminated and the 
source of the release, if known.
    (v) The as-found PCB concentrations in the PCB waste, unless the 
materials are being managed as if they contain >=500 ppm PCBs. If 
actual PCB concentrations have not yet been determined, then estimated 
concentrations may be provided in the request. Actual PCB 
concentrations shall be determined before disposal activities commence, 
unless the waste is being managed as if it contains >=500 ppm PCBs.
    (vi) The provisions of Sec. Sec.  761.60, 761.61, 761.62, or 761.65 
that the person requests to waive or modify (or to use alternative 
procedures for) and an explanation of why compliance with the existing 
provisions would be impracticable as a result of the emergency 
situation.
    (vii) The plan for how sampling, extraction, analysis, storage, 
cleanup, and/or disposal of the PCB waste would be conducted if the 
waiver were granted. The plan shall provide information to support how 
the actions described in the plan do not pose an unreasonable risk of 
injury to health or the environment. This plan shall be based on the 
as-found PCB concentrations in the materials unless waste is being 
managed as if it contains PCBs >=500 ppm.
    (viii) Whether or not the PCB waste is near, or likely to impact, 
surface waters, ground waters, drinking water sources or distribution 
systems, wells, sediments, sewers or sewage treatment systems, grazing 
lands, vegetable gardens, residential dwellings, hospitals, schools, 
nursing homes, playgrounds, parks, day care centers, endangered species 
habitats, estuaries, wetlands, national parks, national wildlife 
refuges, commercial fisheries, or sport fisheries and how those areas 
and potential impacts will be addressed.
    (2) To make changes to submitted information described in paragraph 
(b)(1) of this section, the requestor shall submit the new information 
to the EPA Regional Administrator(s) in writing and/or by email. 
Changes must also be sent to the Director of the State or Tribal 
environmental agency or agencies where the request is applicable.
    (c) Approval of waiver requests. The EPA Regional Administrator may 
approve the waiver request, request additional information, approve the 
waiver request with specified changes or additional conditions, or deny 
the waiver request, in writing, by telephone, or by email. An approval, 
with or without changes or conditions, shall be based on the Regional 
Administrator's

[[Page 59691]]

finding that compliance with the regulatory requirements from which a 
waiver is sought is impracticable and that the action approved under 
the waiver will not pose an unreasonable risk of injury to health or 
the environment. At any point, EPA may impose additional sampling, 
extraction, analysis, cleanup, storage, and/or disposal requirements, 
or require the requestor to delay acting on their proposed plan, in 
order to ensure the actions will not pose an unreasonable risk of 
injury to health or the environment.
    (d) Steps after approval of waiver request. Sampling, extraction, 
analysis, cleanup, storage, and disposal activities as described in the 
waiver request may begin after the EPA Regional Administrator responds 
with approval of the waiver request. All sampling, extraction, 
analysis, cleanup, storage, and disposal activities shall be conducted 
in compliance with the terms of the approval and all applicable 
provisions of Sec. Sec.  761.60, 761.61, 761.62, and 761.65 not 
expressly waived by the approval.
    (e) As-found concentration. Sampling, extraction, analysis, 
cleanup, storage, and disposal activities conducted under this section 
shall be based on the as-found concentration of the PCB waste unless 
the materials are being managed as if they contain >=500 ppm PCBs.
    (f) Records, manifests, and certification. Recordkeeping and 
certification are required in accordance with Sec.  761.125(c)(5). The 
manifesting and reporting requirements in Subpart K apply to waste 
disposed of under this section. However, if the person requesting a 
waiver has not previously submitted a notification of PCB activity as 
described in Sec.  761.205 and the requirements of Sec.  761.205 
specify that such notification is required for the cleanup, storage, 
and/or disposal activity, the requestor shall submit the notification 
within ten (10) business days of their waiver request. The requestor 
does not have to wait to obtain their EPA identification number before 
initiating cleanup and/or disposal activities described in their 
approved waiver request. While waiting for their identification number, 
the requestor may use the generic identification ``40 CFR PART 761'' in 
lieu of an EPA identification number on manifests for PCB waste. The 
requestor may alternatively use an EPA identification number they 
previously obtained from EPA under RCRA or a State or territory under 
an authorized RCRA program, if they have one. Once the requestor 
receives an EPA identification number, they shall use it on manifests 
for PCB waste.

18. Amend Sec.  761.120 by revising paragraphs (b)(2) and (c) to read 
as follows:

Sec.  761.120  Scope.

* * * * *
    (b) * * *
    (2) In those situations, the Regional Administrator may require 
cleanup in addition to that required under Sec.  761.125(b) and (c). 
However, the Regional Administrator must first make a finding, based on 
the specific facts of a spill, that additional cleanup is necessary to 
prevent unreasonable risk. In addition, before making a final decision 
on additional cleanup, the Regional Administrator must notify the 
Director, Office of Resource Conservation and Recovery of their finding 
and the basis for the finding.
    (c) Flexibility to allow less stringent or alternative 
requirements. (1) EPA retains the flexibility to allow less stringent 
or alternative decontamination measures based upon site-specific 
considerations. EPA will exercise this flexibility if the responsible 
party demonstrates that cleanup to the numerical decontamination levels 
is clearly unwarranted because of risk-mitigating factors, that 
compliance with the procedural requirements or numerical standards in 
the policy is impracticable at a particular site, or that site-specific 
characteristics make the costs of cleanup prohibitive. The Regional 
Administrator will notify the Director, Office of Resource Conservation 
and Recovery of any decision and the basis for the decision to allow 
less stringent cleanup. The purpose of this notification is to enable 
the Director, Office of Resource Conservation and Recovery to ensure 
consistency of spill cleanup standards under special circumstances 
across the regions.
    (2) In emergency situations, as defined in Sec.  761.123, the 
following provisions of this Policy are hereby modified as follows:
    (i) For actions taken directly in response to spills caused by 
emergency situations, responsible parties may use the as-found 
concentrations in the spill materials when determining whether to 
manage the spill under Sec. Sec.  761.125(b) or (c) of this Policy when 
it is not possible to readily determine the spill source concentration 
at a site.
    (ii) For spills caused by emergency situations, the applicable 
notifications in Sec.  761.125(a)(1) must be submitted as soon as 
possible, but no later than 48 hours after the adverse conditions that 
prevented communication have ended.

0
a. Adding the definition in alphabetical order for ``Emergency 
situation''; and
0
b. Revising the definitions for ``Other restricted access 
(nonsubstation) locations'' and ``Spill''.
    The addition and revisions read as follows:

Sec.  761.123  Definitions.

* * * * *
    Emergency situation means adverse conditions caused by manmade or 
natural incidents that threaten lives, property, or public health and 
safety; require prompt responsive action from the local, State, Tribal, 
territorial, or Federal government; and result in or are reasonably 
expected to result in: (1) A declaration by either the President of the 
United States or Governor of the affected State of a natural disaster 
or emergency; or, (2) an incident funded under FEMA via a Stafford Act 
disaster declaration or emergency declaration. Examples of emergency 
situations may include civil emergencies or adverse natural conditions, 
such as hurricanes, earthquakes, or tornados.
* * * * *
    Other restricted access (nonsubstation) locations means areas other 
than electrical substations that are at least 0.1 kilometer (km) from a 
residential/commercial area and limited by man-made barriers (e.g., 
fences and walls) or substantially limited by naturally occurring 
barriers such as mountains, cliffs, or rough terrain. These areas 
generally include industrial facilities and extremely remote rural 
locations. (Areas where access is restricted but are less than 0.1 km 
from a residential/commercial area are considered to be residential/
commercial areas.)
* * * * *
    Spill means both intentional and unintentional spills, leaks, and 
other uncontrolled discharges where the release results in any quantity 
of PCBs running off or about to run off the external surface of the 
equipment or other PCB source, as well as the contamination resulting 
from those releases. This policy applies to spills of 50 ppm or greater 
PCBs. The concentration of PCBs spilled is determined by the PCB 
concentration in the material spilled as opposed to the concentration 
of PCBs in the material onto which the PCBs were spilled, except where 
authorized in Sec.  761.120(c). Where a spill of untested mineral oil 
occurs, the oil is presumed to contain greater than or equal to 50 ppm, 
but less than 500 ppm PCBs and is subject to the relevant requirements 
of this policy.

20. Amend Sec.  761.125 by revising paragraphs (a)(2), (c)(3)(iii), and 
(c)(4)(iv) to read as follows:

[[Page 59693]]

Sec.  761.125  Requirements for PCB spill cleanup.

    (a) * * *
    (2) Disposal of cleanup debris and materials. All concentrated 
soils, solvents, rags, and other materials resulting from the cleanup 
of PCBs under this policy shall be properly stored, labeled, and 
disposed of in accordance with the provisions of Subpart D of this 
part, except that such materials shall not be disposed of in a 
hazardous waste landfill permitted by EPA under section 3005 of RCRA or 
by a State or territory authorized under section 3006 of RCRA pursuant 
to Sec.  761.61(b)(2)(ii)(A).
* * * * *
    (c) * * *
    (3) * * *
    (iii) At the option of the responsible party, low-contact, indoor, 
nonimpervious surfaces will be cleaned either to 10 [mu]g/100 cm\2\ or 
to 100 [mu]g/100 cm\2\ and encapsulated. The Regional Administrator, 
however, retains the authority to disallow the encapsulation option for 
a particular spill situation upon finding that the uncertainties 
associated with that option pose special concerns at that site. That 
is, the Regional Administrator would not permit encapsulation if they 
determine that if the encapsulation failed the failure would create an 
imminent hazard at the site.
* * * * *
    (4) * * *
    (iv) At the option of the responsible party, low-contact, outdoor, 
nonimpervious solid surfaces shall be either cleaned to 10 [mu]g/100 
cm\2\ or cleaned to 100 [mu]g/100 cm\2\ and encapsulated. The Regional 
Administrator, however, retains the authority to disallow the 
encapsulation option for a particular spill situation upon finding that 
the uncertainties associated with that option pose special concerns at 
that site. That is, the Regional Administrator would not permit 
encapsulation if they determine that if the encapsulation failed the 
failure would create an imminent hazard at the site.

21. Amend Sec.  761.130 by revising paragraph (e) to read as follows:

Sec.  761.130  Sampling requirements.

* * * * *
    (e) EPA recommends the use of a sampling scheme developed by the 
Midwest Research Institute (MRI) for use in enforcement inspections: 
``Verification of PCB Spill Cleanup by Sampling and Analysis.'' 
Guidance for the use of this sampling scheme is available in the MRI 
report ``Field Manual for Grid Sampling of PCB Spill Sites to Verify 
Cleanup.'' Both the MRI sampling scheme and the guidance document are 
available on EPA's PCB website at https://www.epa.gov/pcbs, or from the 
Program Implementation and Information Division, Office of Resource 
Conservation and Recovery (5303T), 1200 Pennsylvania Ave. NW, 
Washington, DC 20460-0001. The major advantage of this sampling scheme 
is that it is designed to characterize the degree of contamination 
within the entire sampling area with a high degree of confidence while 
using fewer samples than any other grid or random sampling scheme. This 
sampling scheme also allows some sites to be characterized on the basis 
of composite samples.

waste in PCB Transformers, bulk PCB waste, PCB waste in PCB Containers, 
and other PCB waste in storage at the facility at the beginning of the 
calendar year, received or generated at the facility, transferred to 
another facility, or disposed of at the facility during the calendar 
year. The information must be provided for each of these categories, as 
appropriate.
* * * * *
    (v) The total weight in kilograms of each of the following PCB 
categories: PCB waste in PCB Large High or Low Voltage Capacitors, PCB 
waste in PCB Article Containers, PCB waste in PCB Transformers, bulk 
PCB waste, PCB waste in PCB Containers, and other PCB waste remaining 
in storage for disposal at the facility at the end of the calendar year
* * * * *
    (4) Whenever a commercial storer of PCB waste accepts PCBs or PCB 
Items at their storage facility and transfers the PCB waste off-site to 
another facility for storage or disposal, the commercial storer of PCB 
waste shall initiate a manifest under subpart K of this part for the 
transfer of PCBs or PCB Items to the next storage or disposal facility.

    Note 1 to paragraph (b)(4):  Any requirements for weights in 
kilograms of PCBs may be calculated values if the internal volume of 
PCBs in containers and transformers is known and included in the 
reports, together with any assumptions on the density of the PCBs 
contained in the containers or transformers. If the internal volume 
of PCBs is not known, a best estimate may be used.

24. Amend Sec.  761.207 by revising paragraph (a), and paragraph (c) 
and to read as follows:

Sec.  761.207  The manifest--general requirements.

    (a) A generator who transports, or offers for transport, PCB waste 
for commercial off-site storage or off-site disposal, and a commercial 
storage or disposal facility who offers for transport a rejected load 
of PCB waste, must prepare a manifest on EPA Form 8700-22 and, if 
necessary, a continuation sheet. The generator shall specify:
    (1) For each bulk load of PCBs, the identity of the PCB waste, the 
earliest date of removal from service for disposal, and the weight in 
kilograms of the PCB waste. (Item 14--Special Handling Instructions 
box)
    (2) For each PCB transformer, the serial number if available, or 
other identification if there is no serial number; the date of removal 
from service for disposal; and weight in kilograms of the PCB waste in 
each PCB transformer. (Item 14--Special Handling Instructions box)
    (3) For each PCB Large High or Low Voltage Capacitor, the serial 
number if available, or other identification if there is no serial 
number; the date of removal from service for disposal; and weight in 
kilograms of the PCB waste in each PCB Large High or Low Voltage 
Capacitor. (Item 14--Special Handling Instructions box)
    (4) For each PCB Article Container, the unique identifying number, 
type of PCB waste (e.g., small capacitors), earliest date of removal 
from service for disposal, and weight in kilograms of the PCB waste 
contained therein. (Item 14--Special Handling Instructions box)
    (5) For each PCB Container, the unique identifying number, type of 
PCB waste (e.g., soil, debris, small capacitors), earliest date of 
removal from service for disposal, and weight in kilograms of the PCB 
waste contained therein. (Item 14--Special Handling Instructions box)
    (6) For each Other item, the type of PCB waste (e.g., small 
capacitors, circuit breakers, PCB-Contaminated transformers, pipeline), 
earliest date of removal from service for disposal, and weight in 
kilograms of the PCB waste.

    Note 1 to paragraph (a):  EPA Form 8700-22A is not required as 
the PCB manifest continuation sheet. In practice, form 8700-22A does 
not have adequate space to list required PCB-specific information 
for several PCB articles. However, if form 8700-22A fits the needs 
of the user community, the form is permissible.

    Note 2 to paragraph (a):  PCB waste handlers should use the EPA 
Form 8700-22 instructions as a guide, but should defer to the Part 
761 manifest regulations whenever there is any difference between 
the Part 761 requirements and the instructions. The differences 
should be minimal.

    Note 3 to paragraph (a):  PCBs are not regulated under RCRA, 
thus do not have a RCRA waste code. EPA does not require boxes 13 
and 31 on forms 8700-22 and 8700-22A (if used), respectively, to be 
completed for shipments only containing PCB waste. However, some 
States track PCB wastes as State-regulated hazardous wastes, and 
assign State hazardous waste codes to these wastes. In such a case, 
the user should follow the State instructions for completing the 
waste code fields.

* * * * *
    (c) A generator may also designate on the manifest one alternate 
facility which is approved to handle their PCB waste in the event an 
emergency prevents delivery of the waste to the primary designated 
facility.

accordance with Sec.  761.210(a) for three years or until they receive 
a signed copy from the designated facility which received the PCB 
waste. This signed copy must be retained as a record for at least three 
years from the date the waste was accepted by the initial transporter.

from an offsite source without an accompanying manifest, or without an 
accompanying shipping paper as described by Sec.  761.211(e), and the 
owner or operator of the commercial storage or disposal facility cannot 
contact the generator of the PCB waste, then they shall notify the 
Regional Administrator of the EPA region in which their facility is 
located of the unmanifested PCB waste so that the Regional 
Administrator can determine whether further actions are required before 
the owner or operator may store or dispose of the unmanifested PCB 
waste, and additionally the owner or operator must prepare and submit a 
letter to the Regional Administrator within 15 days after receiving the

    (2) Divide the total number of segments, save one, by six. The 
resulting number is the interval between the segments you will sample. 
Do not round this interval. For example, cut a 2.9-mile length of pipe 
into segments of no more than 40 feet by first, dividing 2.9 miles 
(15,312 feet) by 40 feet per segment, resulting in 382.8 total 
segments. Do not round this result. Subtract 1 from the total number of 
segments and then divide the remaining number of segments, 381.8, by 
six. The resulting number in this example is 63.6. Do not round. Add 
63.6 to the first segment (number 1) to select segment 64.6. Next, add 
63.6 to 64.6 to select segment 128.3. Continue in this fashion to 
select all seven segments: 1, 64.6, 128.3, 191.9, 255.5, 319.2, and 
382.8. Now round these numbers to the nearest whole number to determine
