                          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 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

[[Page 651]]

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).
    (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

[[Page 652]]

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, 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.

[[Page 653]]

    (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-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.

[[Page 654]]

    (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.
    (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.

[[Page 655]]

    (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 =500 ppm PCBs to a PCB-
Contaminated transformer (=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 =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 =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):

----------------------------------------------------------------------------------------------------------------
                                   and you retrofill                       and test results
  If test results show the PCB      the transformer                          show the PCB          then the

    (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 
=50 but <500 ppm PCBs. If you discover that the PCB 
concentration of the fluid has risen to =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

    (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.

    (g) [Reserved]
    (h) Use in and servicing of electromagnets, switches and voltage 
regulators. PCBs at any concentration may be used in electromagnets, 
switches (including sectionalizers and motor starters), and voltage 
regulators and may be used for purposes of servicing this equipment 
(including rebuilding) for the remainder of their useful lives, subject 
to the following conditions:
    (1) Use conditions. (i) After October 1, 1985, the use and storage 
for reuse of any electromagnet which poses an exposure risk to food or 
feed is prohibited if the electromagnet contains greater than 500 ppm 
PCBs.
    (ii) Use and storage for reuse of voltage regulators which contain 
1.36 kilograms (3 lbs) or more of dielectric fluid with a PCB 
concentration of =500 ppm are subject to the following 
provisions:
    (A) The owner of the voltage regulator must mark its location in 
accordance with Sec.  761.40.
    (B) If a voltage regulator is involved in a fire-related incident, 
the owner must immediately report the incident to the National Response 
Center (Toll-free: 1-800-424-8802; in Washington, DC: 202-426-2675). A 
fire-related incident is defined as any incident that involves the 
generation of sufficient heat and/or pressure, by any source, to result 
in the violent or non-violent rupture of the voltage regulator and the 
release of PCBs.
    (C) The owner of the voltage regulator must inspect it in accordance 
with the requirements of paragraphs (a)(1)(ix), (a)(1)(xiii), and 
(a)(1)(xiv) of this section that apply to PCB Transformers.
    (D) The owner of the voltage regulator must comply with the 
recordkeeping and reporting requirements at Sec.  761.180.
    (iii) The owner of a voltage regulator that assumes it contains <500 
ppm PCBs as provided in Sec.  761.2, and discovers by testing that it is 
contaminated at =500 ppm PCBs, must comply with paragraph 
(h)(1)(ii)(A) of this section 7 days after the discovery, and paragraphs 
(h)(1)(ii)(B), (h)(1)(ii)(C), and (h)(1)(ii)(D) of this section 
immediately upon discovery.
    (2) Servicing conditions. (i) Servicing (including rebuilding) any 
electromagnet, switch, or voltage regulator with a PCB concentration of 
500 ppm or greater which requires the removal and rework of the internal 
components is prohibited.
    (ii) Electromagnets, switches, and voltage regulators 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.
    (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 electromagnets switches, and 
voltage regulators with a PCB concentration of at least 500 ppm 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 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 
=500 ppm PCBs to PCB-Contaminated status (=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 =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 =1,000 ppm PCBs. 
Retrofill the electromagnet, switch, or voltage regulator with fluid 
containing known PCB levels according to the following table. Determine 
the electromagnet, switch, or voltage regulator's reclassified status 
according to the following table (if following this process

voltage regulator has risen to =500 ppm, follow paragraph 
(h)(1)(iii) of this section to come into compliance with the regulations 
applicable to voltage regulators containing =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.

persons who are granted an exemption under TSCA 6(e)(3)(B).
    (i) Use and reuse of PCBs in natural gas pipeline systems; use and 
reuse of PCB-Contaminated natural gas pipe and appurtenances. (1)(i) 
PCBs are authorized for use in natural gas pipeline systems at 
concentrations <50 ppm.
    (ii) PCBs are authorized for use, at concentrations =50 
ppm, in 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 
=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 =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 =50 ppm in 
natural gas pipeline 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 =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 =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 =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 =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 
=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 
=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), 
where such sources have been demonstrated through historical data or 
recent sampling to contain PCBs =50 ppm.
    (B) Owners or operators of natural gas pipeline systems which do not 
include potential sources of PCB contamination as described in paragraph 
(i)(1)(iii)(A)(3) of this section containing =50 ppm PCB are 
not subject to paragraphs (i)(1)(iii)(A)(2), (i)(1)(iii)(A)(3), 
(i)(1)(iii)(A)(4), or (i)(1)(iii)(A)(6) of this section. Owners or 
operators of these systems, however, must comply with the other 
provisions of this section (e.g., sampling of any collected PCB liquids 
and recordkeeping).
    (C) The owner or operator of a natural gas pipeline system must 
document in writing all data collected and actions taken, or not taken, 
pursuant to the authorization in paragraph (i)(1)(iii)(A) of this 
section. They must maintain the information for 3 years after the PCB 
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

[[Page 660]]

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 
section. They may use documented historical actions taken to reduce PCB 
concentrations in known sources; decontaminate components or segments of 
natural gas pipeline systems; or otherwise to reduce PCB levels to 
fulfill the requirements of paragraph (i)(1)(iii)(A)(4) of this section.
    (2) Any person may reuse PCB-Contaminated natural gas pipe and 
appurtenances in a natural gas pipeline system, provided all free-
flowing liquids have been removed.
    (3) Any person may use PCB-Contaminated natural gas pipe, drained of 
all free-flowing liquids, in the transport of liquids (e.g., bulk 
hydrocarbons, chemicals, petroleum products, or coal slurry), as casing 
to provide secondary containment or protection (e.g., protection for 
electrical cable), as industrial structural material (e.g., fence posts, 
sign posts, or bridge supports), as temporary flume at construction 
sites, as equipment skids, as culverts under transportation systems in 
intermittent flow situations, for sewage service with written consent of 
the Publicly Owned Treatment Works (POTW), for steam service, as 
irrigation systems (<20 inch diameter) of less than 200 miles in length, 
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 
=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 PCB concentration at the time of removal 
from the system. Any person disposing of materials contaminated by 
spills or other releases of PCBs =50 ppm from a natural gas 
pipeline systems, must do so in accordance with Sec. Sec.  761.61 or 
761.79, as applicable.
    (ii) Any person who markets or burns for energy recovery liquids 
containing PCBs at concentrations <50 ppm PCBs at the time of removal 
from a natural gas pipeline system must do so in accordance with the 
provisions pertaining to used oil at Sec.  761.20(e). No other use of 
liquid containing PCBs at concentrations above the quantifiable level/
level of detection removed from a natural gas pipeline system is 
authorized.
    (j) Research and development. For purposes of this section, 
authorized research and development (R&D) activities include, but are 
not limited to: the chemical analysis of PCBs, including analyses to 
determine PCB concentration; determinations of the physical properties 
of PCBs; studies of environmental transport processes; studies of 
biochemical transport processes; studies of effects of PCBs on the 
environment; and studies of the health effects of PCBs, including direct 
toxicity and toxicity of metabolic products of PCBs. Authorized R&D 
activities do not include research, development, or analysis for the

activities under this section is also responsible for determining and 
complying with all other applicable Federal, State, and local laws and 
regulations. Although the use of PCBs and PCBs in analytical reference 
samples derived from waste material is authorized in conjunction with 
PCB-disposal related activities, R&D for PCB disposal (as defined under 
Sec.  761.3) is addressed in Sec.  761.60(j). PCBs and PCBs in 
analytical reference samples derived from waste materials are authorized 
for use, in a manner other than a totally enclosed manner, provided 
that:
    (1) They obtain the PCBs and PCBs in analytical reference samples 
derived from waste materials from sources authorized under Sec.  761.80 
to manufacture, process, and distribute PCBs in commerce and the PCBs 
are packaged in compliance with the Hazardous Materials Regulations at 
49 CFR parts 171 through 180.
    (2) They store all PCB wastes resulting from R&D activities (e.g., 
spent laboratory samples, residuals, contaminated media such as 
clothing, etc.) in compliance with Sec.  761.65(b) and dispose of all 
PCB wastes in compliance with Sec.  761.64.
    (3) [Reserved]
    (4) No person may manufacture, process, or distribute in commerce 
PCBs for research and development unless they have been granted an 
exemption to do so under TSCA section 6(e)(3)(B).
    (k) Use in scientific instruments. PCBs may be used indefinitely in 
scientific instruments, for example, in oscillatory flow birefringence 
and viscoelasticity instruments for the study of the physical properties 
of polymers, as microscopy mounting fluids, as microscopy immersion oil, 
and as optical liquids in a manner other than a totally enclosed manner. 
No person may manufacture, process, or distribute in commerce PCBs for 
use in scientific instruments unless they have been granted an exemption 
to do so under TSCA section 6(e)(3)(B).
    (l) Use in capacitors. PCBs at any concentration may be used in 
capacitors, subject to the following conditions:

Capacitors which pose an exposure risk to food or feed is prohibited.
    (ii) After October 1, 1988, the use of PCB Large High Voltage 
Capacitors and PCB Large Low Voltage Capacitors is prohibited unless the 
capacitor is used within a restricted-access electrical substation or in 
a contained and restricted-access indoor installation. A restricted-
access electrical substation is an outdoor, fenced or walled-in facility 
that restricts public access and is used in the transmission or 
distribution of electric power. A contained and restricted-access indoor 
installation does not have public access and has an adequate roof, 
walls, and floor to contain any release of PCBs within the indoor 
location.
    (2) [Reserved]
    (m) Use in and servicing of circuit breakers, reclosers and cable. 
PCBs at any concentration may be used in circuit breakers, reclosers, 
and cable and may be used for purposes of servicing this electrical 
equipment (including rebuilding) for the remainder of their useful 
lives, subject to the following conditions:
    (1) Servicing conditions. (i) Circuit breakers, reclosers, and cable 
may be serviced (including rebuilding) only with dielectric fluid 
containing less than 50 ppm PCB.
    (ii) Any circuit breaker, recloser or cable found to contain at 
least 50 ppm PCBs may be serviced only in accordance with the conditions 
contained in 40 CFR 761.30(h)(2).
    (2) [Reserved]
    (n)-(o) [Reserved]
    (p) Continued use of porous surfaces contaminated with PCBs 
regulated for disposal by spills of liquid PCBs. (1) Any person may use 
porous surfaces contaminated by spills of liquid PCBs at concentrations 
10 [micro]g/100 cm\2\ for the remainder of the useful life of 
the surfaces and subsurface material if the following conditions are 
met:
    (i) The source of PCB contamination is removed or contained to 
prevent further release to porous surfaces.
    (ii) If the porous surface is accessible to superficial surface 
cleaning:
    (A) The double wash rinse procedure in subpart S of this part is 
conducted on the surface to remove surface PCBs.

[[Page 662]]

    (B) The treated surface is allowed to dry for 24 hours.
    (iii) After accessible surfaces have been cleaned according to 
paragraph (p)(1)(ii) of this section and for all surfaces inaccessible 
to cleanup:
    (A) The surface is completely covered to prevent release of PCBs 
with:
    (1) Two solvent resistant and water repellent coatings of 
contrasting colors to allow for a visual indication of wear through or 
loss of outer coating integrity; or
    (2) A solid barrier fastened to the surface and covering the 
contaminated area or all accessible parts of the contaminated area. 
Examples of inaccessible areas are underneath a floor-mounted electrical 
transformer and in an impassible space between an electrical transformer 
and a vault wall.
    (B) The surface is marked with the ML Mark in a location 
easily visible to individuals present in the area; the ML 
Mark shall be placed over the encapsulated area or the barrier to the 
encapsulated area.
    (C) ML Marks shall be replaced when worn or illegible.
    (2) Removal of a porous surface contaminated with PCBs from its 
location or current use is prohibited except for removal for disposal in 
accordance with Sec. Sec.  761.61 or 761.79 for surfaces contaminated by 
spills, or Sec.  761.62 for manufactured porous surfaces.
    (q) [Reserved]
