TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 761--POLYCHLORINATED BIPHENYLS (PCBs) MANUFACTURING, PROCESSING,
DISTRIBUTION IN COMMERCE, AND USE PROHIBITIONS--Table of Contents
Subpart B--Manufacturing, Processing, Distribution in Commerce, and Use
of PCBs and PCB Items
Sec. 761.30 Authorizations.
The following non-totally enclosed PCB activities are authorized
pursuant to section 6(e)(2)(B) of TSCA:
(a) Use in and servicing of transformers (other than railroad
transformers). PCBs at any concentration may be used in transformers
(other than in railroad locomotives and self-propelled railroad cars)
and may be used for purposes of servicing including rebuilding these
transformers for the remainder of their
[[Page 597]]
useful lives, subject to the following conditions:
(1) Use conditions. (i) As of October 1, 1985, the use and storage
for reuse of PCB Transformers that pose an exposure risk to food or feed
is prohibited.
(ii) As of October 1, 1990, the use of network PCB Transformers with
higher secondary voltages (secondary voltages equal to or greater than
480 volts, including 480/277 volt systems) in or near commercial
buildings is prohibited. Network PCB Transformers with higher secondary
voltages which are removed from service in accordance with this
requirement must either be reclassified to PCB Contaminated or non PCB
status, placed into storage for disposal, or disposed.
(iii) Except as otherwise provided, as of October 1, 1985, the
installation of PCB Transformers, which have been placed into storage
for reuse or which have been removed from another location, in or near
commercial buildings is prohibited.
(A) Retrofilled mineral oil PCB Transformers may be installed for
reclassification purposes indefinitely after October 1, 1990.
(B) Once a retrofilled transformer has been installed for
reclassification purposes, it must be tested 3 months after installation
to ascertain the concentration of PCBs. If the PCB concentration is
below 50 ppm, the transformer can be reclassified as a non-PCB
Transformer. If the PCB concentration is between 50 and 500 ppm, the
transformer can be reclassified as a PCB-Contaminated transformer. If
the PCB concentration remains at 500 ppm or greater, the entire process
must either be repeated until the transformer has been reclassified to a
non-PCB or PCB-Contaminated transformer in accordance with paragraph
(a)(2)(v) of this section or the transformer must be removed from
service.
(iv) As of October 1, 1990, all higher secondary voltage radial PCB
Transformers, in use in or near commercial buildings, and lower
secondary voltage network PCB Transformers not located in sidewalk
vaults in or near commercial buildings (network transformers with
secondary voltages below 480 volts) that have not been removed from
service as provided in paragraph (a)(1)(iv)(B) of this section, must be
equipped with electrical protection to avoid transformer ruptures caused
by high current faults. As of February 25, 1991, all lower secondary
voltage radial PCB Transformers, in use in or near commercial buildings,
must be equipped with electrical protection to avoid transformer
ruptures caused by high current faults.
(A) Current-limiting fuses or other equivalent technology must be
used to detect sustained high current faults and provide for the
complete deenergization of the transformer (within several hundredths of
a second in the case of higher secondary voltage radial PCB Transformers
and within tenths of a second in the case of lower secondary voltage
network PCB Transformers), before transformer rupture occurs. Lower
secondary voltage radial PCB Transformers must be equipped with
electrical protection as provided in paragraph (a)(1)(iv)(E) of this
section. The installation, setting, and maintenance of current-limiting
fuses or other equivalent technology to avoid PCB Transformer ruptures
from sustained high current faults must be completed in accordance with
good engineering practices.
(B) All lower secondary voltage network PCB Transformers not located
in sidewalk vaults (network transformers with secondary voltages below
480 volts), in use in or near commercial buildings, which have not been
protected as specified in paragraph (a)(1)(iv)(A) of this section by
October 1, 1990, must be removed from service by October 1, 1993.
(C) As of October 1, 1990, owners of lower secondary voltage network
PCB Transformers, in use in or near commercial buildings which have not
been protected as specified in paragraph (a)(1)(iv)(A) of this section
and which are not located in sidewalk vaults, must register in writing
those transformers with the EPA Regional Administrator in the
appropriate region. The information required to be provided in writing
to the Regional Administrator includes:
(1) The specific location of the PCB Transformer(s).
[[Page 598]]
(2) The address(es) of the building(s) and the physical location of
the PCB Transformer(s) on the building site(s).
(3) The identification number(s) of the PCB Transformer(s).
(D) As of October 1, 1993, all lower secondary voltage network PCB
Transformers located in sidewalk vaults (network transformers with
secondary voltages below 480 volts) in use near commercial buildings
must be removed from service.
(E) As of February 25, 1991, all lower secondary voltage radial PCB
Transformers must be equipped with electrical protection, such as
current-limiting fuses or other equivalent technology, to detect
sustained high current faults and provide for the complete
deenergization of the transformer or complete deenergization of the
faulted phase of the transformer within several hundredths of a second.
The installation, setting, and maintenance of current-limiting fuses or
other equivalent technology to avoid PCB Transformer ruptures from
sustained high current faults must be completed in accordance with good
engineering practices.
(v) As of October 1, 1990, all radial PCB Transformers with higher
secondary voltages (480 volts and above, including 480/277 volt systems)
in use in or near commercial buildings must, in addition to the
requirements of paragraph (a)(1)(iv)(A) of this section, be equipped
with protection to avoid transformer ruptures caused by sustained low
current faults.
(A) Pressure and temperature sensors (or other equivalent technology
which has been demonstrated to be effective in early detection of
sustained low current faults) must be used in these transformers to
detect sustained low current faults.
(B) Disconnect equipment must be provided to insure complete
deenergization of the transformer in the event of a sensed abnormal
condition (e.g., an overpressure or overtemperature condition in the
transformer), caused by a sustained low current fault. The disconnect
equipment must be configured to operate automatically within 30 seconds
to 1 minute of the receipt of a signal indicating an abnormal condition
from a sustained low current fault, or can be configured to allow for
manual deenergization from a manned on-site control center upon the
receipt of an audio or visual signal indicating an abnormal condition
caused by a sustained low current fault. Manual deenergization from a
manned on-site control center must occur within 1 minute of the receipt
of the audio or visual signal indicating an abnormal condition caused by
a sustained low current fault. If automatic operation is selected and a
circuit breaker is utilized for disconnection, it must also have the
capability to be manually opened if necessary.
(C) The enhanced electrical protective system required for the
detection of sustained low current faults and the complete and rapid
deenergization of transformers must be properly installed, maintained,
and set sensitive enough (in accordance with good engineering practices)
to detect sustained low current faults and allow for rapid and total
deenergization prior to PCB Transformer rupture (either violent or non
violent rupture) and release of PCBs.
(vi)(A) No later than December 28, 1998 all owners of PCB
Transformers, including those in storage for reuse, must register their
transformers with the Environmental Protection Agency, National Program
Chemicals Division, Office of Pollution Prevention and Toxics (7404),
1200 Pennsylvania Ave., NW., Washington, DC 20460. This registration
requirement is subject to the limitations in paragraph (a)(1) of this
section.
(1) A transformer owner who assumes a transformer is a PCB-
Contaminated transformer, and discovers after December 28, 1998 that it
is a PCB-Transformer, must register the newly-identified PCB
Transformer, in writing, with the Environmental Protection Agency no
later than 30 days after it is identified as such. This requirement does
not apply to transformer owners who have previously registered with the
EPA PCB Transformers located at the same address as the transformer that
they assumed to be PCB-Contaminated and later determined to be a PCB
Transformer.
(2) A person who takes possession of a PCB Transformer after
December 28,
[[Page 599]]
1998 is not required to register or re-register the transformer with the
EPA.
(B) Any person submitting a registration under this section must
include:
(1) Company name and address.
(2) Contact name and telephone number.
(3) Address where these transformers are located. For mobile sources
such as ships, provide the name of the ship.
(4) Number of PCB Transformers and the total weight in kilograms of
PCBs contained in the transformers.
(5) Whether any transformers at this location contain flammable
dielectric fluid (optional).
(6) Signature of the owner, operator, or other authorized
representative certifying the accuracy of the information submitted.
(C) A transformer owner must retain a record of each PCB
Transformer's registration (e.g., a copy of the registration and the
return receipt signed by EPA) with the inspection and maintenance
records required for each PCB Transformer under paragraph (a)(1)(xii)(I)
of this section.
(D) A transformer owner must comply with all requirements of
paragraph (a)(1)(vi)(A) of this section to continue the PCB-
Transformer's authorization for use, or storage for reuse, pursuant to
this section and TSCA section 6(e)(2)(B).
(vii) As of December 1, 1985, PCB Transformers in use in or near
commercial buildings must be registered with building owners. For PCB
Transformers located in commercial buildings, PCB Transformer owners
must register the transformers with the building owner of record. For
PCB Transformers located near commercial buildings, PCB Transformer
owners must register the transformers with all owners of buildings
located within 30 meters of the PCB Transformer(s). Information required
to be provided to building owners by PCB Transformer owners includes but
is not limited to:
(A) The specific location of the PCB Transformer(s).
(B) The principal constituent of the dielectric fluid in the
transformer(s) (e.g., PCBs, mineral oil, or silicone oil).
(C) The type of transformer installation (e.g., 208/120 volt
network, 208/120 volt radial, 208 volt radial, 480 volt network, 480/277
volt network, 480 volt radial, 480/277 volt radial).
(viii) As of December 1, 1985, combustible materials, including, but
not limited to paints, solvents, plastics, paper, and sawn wood must not
be stored within a PCB Transformer enclosure (i.e., in a transformer
vault or in a partitioned area housing a transformer); within 5 meters
of a transformer enclosure, or, if unenclosed (unpartitioned), within 5
meters of a PCB Transformer.
(ix) A visual inspection of each PCB Transformer (as defined in the
definition of ``PCB Transformer'' under Sec. 761.3) in use or stored for
reuse shall be performed at least once every 3 months. These inspections
may take place any time during the 3-month periods: January-March,
April-June, July-September, and October-December as long as there is a
minimum of 30 days between inspections. The visual inspection must
include investigation for any leak of dielectric fluid on or around the
transformer. The extent of the visual inspections will depend on the
physical constraints of each transformer installation and should not
require an electrical shutdown of the transformer being inspected.
(x) If a PCB Transformer is found to have a leak which results in
any quantity of PCBs running off or about to run off the external
surface of the transformer, then the transformer must be repaired or
replaced to eliminate the source of the leak. In all cases any leaking
material must be cleaned up and properly disposed of according to
disposal requirements of subpart D of this part. Cleanup of the released
PCBs must be initiated as soon as possible, but in no case later than 48
hours of its discovery. Until appropriate action is completed, any
active leak of PCBs must be contained to prevent exposure of humans or
the environment and inspected daily to verify containment of the leak.
Trenches, dikes, buckets, and pans are examples of proper containment
measures.
(xi) If a PCB Transformer is involved in a fire-related incident,
the owner of the transformer must immediately report the incident to the
National Response Center (toll-free 1-800-424-8802; in Washington, DC
202-426-2675). A fire-
[[Page 600]]
related incident is defined as any incident involving a PCB Transformer
which involves the generation of sufficient heat and/or pressure (by any
source) to result in the violent or non-violent rupture of a PCB
Transformer and the release of PCBs. Information must be provided
regarding the type of PCB Transformer installation involved in the fire-
related incident (e.g., high or low secondary voltage network
transformer, high or low secondary voltage simple radial system,
expanded radial system, primary selective system, primary loop system,
or secondary selective system or other systems) and the readily
ascertainable cause of the fire-related incident (e.g., high current
fault in the primary or secondary or low current fault in secondary).
The owner of the PCB Transformer must also take measures as soon as
practically and safely possible to contain and control any potential
releases of PCBs and incomplete combustion products into water. These
measures include, but are not limited to:
(A) The blocking of all floor drains in the vicinity of the
transformer.
(B) The containment of water runoff.
(C) The control and treatment (prior to release) of any water used
in subsequent cleanup operations.
(xii) Records of inspection and maintenance history shall be
maintained at least 3 years after disposing of the transformer and shall
be made available for inspection, upon request by EPA. Such records
shall contain the following information for each PCB Transformer:
(A) Its location.
(B) The date of each visual inspection and the date that leak was
discovered, if different from the inspection date.
(C) The person performing the inspection.
(D) The location of any leak(s).
(E) An estimate of the amount of dielectric fluid released from any
leak.
(F) The date of any cleanup, containment, repair, or replacement.
(G) A description of any cleanup, containment, or repair performed.
(H) The results of any containment and daily inspection required for
uncorrected active leaks.
(I) Record of the registration of PCB Transformer(s).
(J) Records of transfer of ownership in compliance with
Sec. 761.180(a)(2)(ix).
(xiii) A reduced visual inspection frequency of at least once every
12 months applies to PCB Transformers that utilize either of the
following risk reduction measures. These inspections may take place any
time during the calendar year as long as there is a minimum of 180 days
between inspections.
(A) A PCB Transformer which has impervious, undrained, secondary
containment capacity of at least 100 percent of the total dielectric
fluid volume of all transformers so contained or
(B) A PCB Transformer which has been tested and found to contain
less than 60,000 ppm PCBs (after 3 months of in service use if the
transformer has been serviced for purposes of reducing the PCB
concentration).
(xiv) An increased visual inspection frequency of at least once
every week applies to any PCB Transformer in use or stored for reuse
which poses an exposure risk to food or feed. The user of a PCB
Transformer posing an exposure risk to food is responsible for the
inspection, recordkeeping, and maintenance requirements under this
section until the user notifies the owner that the transformer may pose
an exposure risk to food or feed. Following such notification, it is the
owner's ultimate responsibility to determine whether the PCB Transformer
poses an exposure risk to food or feed.
(xv) In the event a mineral oil transformer, assumed to contain less
than 500 ppm of PCBs as provided in Sec. 761.2, is tested and found to
be contaminated at 500 ppm or greater PCBs, it will be subject to all
the requirements of this Part 761. In addition, efforts must be
initiated immediately to bring the transformer into compliance in
accordance with the following schedule:
(A) Report fire-related incidents, effective immediately after
discovery.
(B) Mark the PCB transformer within 7 days after discovery.
(C) Mark the vault door, machinery room door, fence, hallway or
other means of access to the PCB Transformer within 7 days after
discovery.
[[Page 601]]
(D) Register the PCB Transformer in writing with the building owner
within 30 days of discovery.
(E) Install electrical protective equipment on a radial PCB
Transformer and a non-sidewalk vault, lower secondary voltage network
PCB Transformer in or near a commercial building within 18 months of
discovery or by October 1, 1990, whichever is later.
(F) Remove a non-sidewalk vault, lower secondary voltage network PCB
Transformer in or near a commercial building, if electrical protective
equipment is not installed, within 18 months of discovery or by October
1, 1993, whichever is later.
(G) Remove a lower secondary voltage network PCB Transformer located
in a sidewalk vault in or near a commercial building, within 18 months
of discovery or by October 1, 1993, whichever is later.
(H) Retrofill and reclassify a radial PCB Transformer or a lower or
higher secondary voltage network PCB Transformer, located in other than
a sidewalk vault in or near a commercial building, within 18 months or
by October 1, 1990, whichever is later. This is an option in lieu of
installing electrical protective equipment on a radial or lower
secondary voltage network PCB Transformer located in other than a
sidewalk vault or of removing a higher secondary voltage network PCB
Transformer or a lower secondary voltage network PCB Transformer,
located in a sidewalk vault, from service.
(I) Retrofill and reclassify a lower secondary voltage network PCB
Transformer, located in a sidewalk vault, in or near a commercial
building within 18 months or by October 1, 1993, whichever is later.
This is an option in lieu of installing electrical protective equipment
or removing the transformer from service.
(J) Retrofill and reclassify a higher secondary voltage network PCB
Transformer, located in a sidewalk vault, in or near a commercial
building within 18 months or by October 1, 1990, whichever is later.
This is an option in lieu of other requirements.
(2) Servicing conditions. (i) Transformers classified as PCB-
Contaminated Electrical Equipment (as defined in the definition of
``PCB-Contaminated Electrical Equipment'' under Sec. 761.3) may be
serviced (including rebuilding) only with dielectric fluid containing
less than 500 ppm PCB.
(ii) Any servicing (including rebuilding) of PCB Transformers (as
defined in the definition of ``PCB Transformer'' under Sec. 761.3) that
requires the removal of the transformer coil from the transformer casing
is prohibited. PCB Transformers may be serviced (including topping off)
with dielectric fluid at any PCB concentration.
(iii) PCBs removed during any servicing activity must be captured
and either reused as dielectric fluid or disposed of in accordance with
the requirements of Sec. 761.60. PCBs from PCB Transformers must not be
mixed with or added to dielectric fluid from PCB-Contaminated Electrical
Equipment.
(iv) Regardless of its PCB concentration, dielectric fluids
containing less than 500 ppm PCB that are mixed with fluids that contain
500 ppm or greater PCB must not be used as dielectric fluid in any
electrical equipment. The entire mixture of dielectric fluid must be
considered to be greater than 500 ppm PCB and must be disposed of in an
incinerator that meets the requirements in Sec. 761.70.
(v) You may reclassify a PCB Transformer that has been tested and
determined to have a concentration of [ge]500 ppm PCBs to a PCB-
Contaminated transformer ([ge]50 but < 500 ppm) or to a non-PCB
transformer (< 50 ppm), and you may reclassify a PCB-Contaminated
transformer that has been tested and determined to have a concentration
of [ge]50 ppm but < 500 ppm to a non-PCB transformer, as follows:
(A) Remove the free-flowing PCB dielectric fluid from the
transformer. Flushing is not required. Either test the fluid or assume
it contains [ge]1,000 ppm PCBs. Retrofill the transformer with fluid
containing known PCB levels according to the following table. Determine
the transformer's reclassified status according to the following table
(if following this process does not result in the reclassified status
you desire, you may repeat the process):
[[Page 602]]
----------------------------------------------------------------------------------------------------------------
and you retrofill and test results
If test results show the PCB the transformer show the PCB then the
concentration (ppm) in the with dielectric and you . . . concentration transformer's
transformer prior to retrofill fluid containing . (ppm) after reclassified
is . . . . . retrofill is . . . status is. . .
----------------------------------------------------------------------------------------------------------------
[ge]1,000 (or untested) < 50 ppm PCBs operate the [ge]50 but < 500 PCB-contaminated
transformer
electrically
under loaded
conditions for at
least 90-
continuous days
after retrofill,
then test the
fluid for PCBs
-------------------------------------------------------------------------------
< 50 ppm PCBs operate the <50 non-PCB
transformer
electrically
under loaded
conditions for at
least 90-
continuous days
after retrofill,
then test the
fluid for PCBs
----------------------------------------------------------------------------------------------------------------
[ge]500 but <1,000 <50 ppm PCBs test the fluid for [ge]50 but <500 PCB-contaminated
PCBs at least 90
days after
retrofill
-------------------------------------------------------------------------------
<50 ppm PCBs test the fluid for <50 non-PCB
PCBs at least 90
days after

----------------------------------------------------------------------------------------------------------------
[ge]50 but <500 [ge]2 but <50 ppm test the fluid for <50 non-PCB
PCBs PCBs at least 90
days after
retrofill
-------------------------------------------------------------------------------
<2 ppm PCBs (no need to test) (not applicable) non-PCB
----------------------------------------------------------------------------------------------------------------
(B) If you discover that the PCB concentration of the fluid in a
reclassified transformer has changed, causing the reclassified status to
change, the transformer is regulated based on the actual concentration
of the fluid. For example, a transformer that was reclassified to non-
PCB status is regulated as a PCB-Contaminated transformer if you
discover that the concentration of the fluid has increased to [ge]50 but
<500 ppm PCBs. If you discover that the PCB concentration of the fluid
has risen to [ge]500 ppm, the transformer is regulated as a PCB
Transformer. Follow paragraphs (a)(1)(xv)(A) through (J) of this section
to come into compliance with the regulations applicable to PCB
Transformers. You also have the option of repeating the reclassification
process.
(C) The Director, National Program Chemicals Division, may, without
further rulemaking, grant approval on a case-by-case basis for the use
of alternative methods to reclassify transformers. You may request an
approval by writing to the Director, National Program Chemicals Division
(7404), Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460. Describe the equipment you plan to reclassify, the
alternative reclassification method you plan to use, and test data or
other evidence on the effectiveness of the method.
(D) You must keep records of the reclassification required by
Sec. 761.180(g).
(vi) Any dielectric fluid containing 50 ppm or greater PCB used for
servicing transformers must be stored in accordance with the storage for
disposal requirements of Sec. 761.65.
(vii) Processing and distribution in commerce of PCBs for purposes
of servicing transformers is permitted only for persons who are granted
an exemption under TSCA 6(e)(3)(B).
(b) Use in and servicing of railroad transformers. PCBs may be used
in transformers in railroad locomotives or railroad self-propelled cars
(``railroad transformers'') and may be processed and distributed in
commerce for purposes of servicing these transformers in a manner other
than a totally enclosed manner subject to the following conditions:
[[Page 603]]

(vi) A PCB Transformer may be converted to a PCB-Contaminated
Transformer or to a non-PCB Transformer by draining, refilling, and/or
otherwise servicing the railroad transformer. In order to reclassify,
the railroad transformer's dielectric fluid must contain less than 500
ppm (for conversion to PCB-Contaminated Transformer) or less than 50 ppm
PCB (for conversion to a non-PCB Transformer) after a minimum of three
months of inservice use subsequent to the last servicing conducted for
the purpose of reducing the PCB concentration in the transformer.
(c) Use in mining equipment. After January 1, 1982, PCBs may be used

Electrical Equipment.
(iv) Regardless of its PCB concentration, dielectric fluids
containing less than 500 ppm PCB that are mixed with fluids that contain
500 ppm or greater PCB must not be used as dielectric fluid in any
electrical equipment. The entire mixture of dielectric fluid must be
considered to be greater than 500 ppm PCB and must be disposed of in an
incinerator that meets the requirements of Sec. 761.70.
(v) You may reclassify an electromagnet, switch, or voltage
regulator that has been tested and determined to have a concentration of
[ge]500 ppm PCBs to PCB-Contaminated status ([ge]50 but <500 ppm) or to
non-PCB status (<50 ppm), and you may reclassify a PCB-Contaminated
electromagnet, switch, or voltage regulator that has been tested and
determined to have a concentration of [ge]50 ppm but <500 ppm to a non-
PCB status, as follows:
(A) Remove the free-flowing PCB dielectric fluid from the
electromagnet, switch, or voltage regulator. Flushing is not required.
Either test the fluid or assume it contains [ge]1,000 ppm PCBs.
Retrofill the electromagnet, switch, or voltage regulator with fluid

(B) If you discover that the PCB concentration of the fluid in a
reclassified electromagnet, switch, or voltage regulator has changed,
causing the reclassified status to change, the electromagnet, switch, or
voltage regulator is regulated based on the actual concentration of the
fluid. For example, an electromagnet, switch, or voltage regulator that
was reclassified to non-PCB status is regulated as a PCB-Contaminated
electromagnet, switch, or voltage regulator if you discover that the
concentration of the fluid has increased to [ge]50 but <500 ppm PCBs. If
you discover that the PCB concentration of the fluid in a voltage
regulator has risen to [ge]500 ppm, follow paragraph (h)(1)(iii) of this
section to come into compliance with the regulations applicable to
voltage regulators containing [ge]500 ppm PCBs. You also have the option
of repeating the reclassification process.
(C) The Director, National Program Chemicals Division may, without
further rulemaking, grant approval on a case-by-case basis for the use
of alternative methods to reclassify electromagnets, switches or voltage
regulators. You may request an approval by writing to the Director,
National Program Chemicals Division (7404), Environmental Protection
Agency,1200 Pennsylvania Ave., NW., Washington, DC 20460. Describe the
equipment you plan to reclassify, the alternative reclassification
method you plan to use, and test data or other evidence on the
effectiveness of the method.
(D) You must keep records of the reclassification required by
Sec. 761.180(g).
(vi) Any dielectric fluid containing 50 ppm or greater PCB used for
servicing electromagnets, switches, or voltage regulators must be stored
in accordance with the storage for disposal requirements of Sec. 761.65.
(vii) Processing and distribution in commerce of PCBs for purposes
of servicing electromagnets, switches or voltage regulators is permitted
only for persons who are granted an exemption under TSCA 6(e)(3)(B).

natural gas pipeline systems not owned or operated by a seller or
distributor of natural gas.
(iii)(A) PCBs are authorized for use, at concentrations [ge]50 ppm,
in natural gas pipeline systems owned or operated by a seller or
distributor of natural gas, if the owner or operator:
(1) Submits to EPA, upon request, a written description of the
general nature and location of PCBs [ge]50 ppm in their natural gas
pipeline system. Each written description shall be submitted to the EPA
Regional Administrator having jurisdiction over the segment or component
of the system (or the Director, National Program Chemicals Division,
Office of Prevention, Pesticides, and Toxic Substances, if the system is
contaminated in more than one region).
(2) Within 120 days after discovery of PCBs [ge]50 ppm in natural
gas pipeline
[[Page 606]]
systems, or by December 28, 1998, whichever is later, characterizes the
extent of PCB contamination by collecting and analyzing samples to
identify the upstream and downstream end points of the segment or
component where PCBs [ge]50 ppm were discovered.
(3) Within 120 days of characterization of the extent of PCB
contamination, or by December 28, 1998, whichever is later, samples and
analyzes all potential sources of introduction of PCBs into the natural
gas pipeline system for PCBs [ge]50 ppm. Potential sources include
natural gas compressors, natural gas scrubbers, natural gas filters, and
interconnects where natural gas is received upstream from the most
downstream sampling point where PCBs [ge]50 ppm were detected; potential
sources exclude valves, drips, or other small liquid condensate
collection points.
(4) Within 1 year of characterization of the extent of PCB
contamination, reduces all demonstrated sources of PCBs [ge]50 ppm to
<50 ppm, or removes such sources from the natural gas pipeline system;
or implements other engineering measures or methods to reduce PCB levels
to <50 ppm and to prevent further introduction of PCBs [ge]50 ppm into
the natural gas pipeline system (e.g., pigging, decontamination, in-line
filtration).
(5) Repeats sampling and analysis at least annually where PCBs are
[ge]50 ppm, until sampling results indicate the natural gas pipeline
segment or component is <50 ppm PCB in two successive samples with a
minimum interval between samples of 180 days.
(6) Marks aboveground sources of PCB liquids in natural gas pipeline
systems with the ML Mark in accordance with Sec. 761.45(a),

concentration in the component or segment is reduced to <50 ppm, and
make it available to EPA upon request.
(D) The Director, National Program Chemicals Division, after
consulting with the appropriate EPA Region(s) may, based on a finding of
no unreasonable risk, modify in writing the requirements of paragraph
(i)(1)(iii)(A) of this section, including extending any compliance date,
approving alternative formats for documentation, waiving one or more
requirements for a segment or component, requiring sampling and
analysis, and requiring implementation of engineering measures to reduce
PCB concentrations. EPA will make such modifications based on the
natural gas pipeline system size, configuration, and current operating
conditions; nature, extent or source of contamination; proximity of
contamination to end-users; or previous sampling, monitoring, remedial
actions or documentation of activities taken regarding compliance with
this authorization or other applicable Federal, State, or local laws and
regulations. The Director, National Program Chemicals Division, may
defer the authority described in this paragraph, upon request, to the
appropriate EPA Region.
(E) The owner or operator of a natural gas pipeline system may use
historical data to fulfill the requirements of paragraphs
(i)(1)(iii)(A)(1), (i)(1)(iii)(A)(2) and (i)(1)(iii)(A)(3) of this

and in a totally enclosed compressed air system.
(4) Any person characterizing PCB contamination in natural gas pipe
or natural gas pipeline systems must do so by analyzing organic liquids
collected at existing condensate collection points in the pipe or
pipeline system. The level of PCB contamination found at a collection
point is assumed to extend to the next collection point downstream. Any
person characterizing multi-phasic liquids must do so in accordance with
Sec. 761.1(b)(4); if no liquids are present, they must use standard wipe
samples in accordance with subpart M of this part.
(5)(i) Any person disposing of liquids containing PCBs [ge]50 ppm
removed, spilled, or otherwise released from a natural gas pipeline
system must do so in accordance with Sec. 761.61(a)(5)(iv) based on the
