PCB Management refers to the EPA rules that govern the use, marking, storage, cleanup and disposal of polychlorinated biphenyls (PCBs). Found in 40 CFR Part 761 under the Toxic Substances Control Act (TSCA), the rules generally regulate materials containing 50 parts per million (ppm) or more of PCBs and set specific requirements for PCB transformers, capacitors, fluorescent light ballasts, spills and PCB waste.
PCBs were widely used in electrical equipment, hydraulic fluids, caulk, paint and other products until their manufacture was banned in 1979. They persist in the environment, build up in the food chain and are linked to cancer and other health effects. Many older industrial plants, utilities, schools and commercial buildings still have PCB-containing equipment or building materials, so facility managers need to know what they have and how to handle it.
What Are the PCB Regulations?
Section 6(e) of TSCA banned the manufacture, processing, distribution in commerce and use of PCBs except in a totally enclosed manner, and allows EPA to authorize certain uses. EPA's rules are at 40 CFR Part 761, and EPA's PCB pages provide guidance. Key subparts include:
- Subpart B: authorized uses, including PCB transformers and capacitors
- Subpart C: marking
- Subpart D: storage and disposal, including PCB remediation waste
- Subpart G: the PCB Spill Cleanup Policy
- Subpart J: recordkeeping and reporting
- Subpart K: manifesting PCB waste
EPA amended Part 761 in 2023 to update testing methods, add flexibility for cleaning up and disposing of PCB remediation waste and clarify other provisions.
Concentration categories
- Below 50 ppm: generally not regulated for use, though some disposal and cleanup rules still apply, and dilution to get below 50 ppm is prohibited
- 50 to 499 ppm: "PCB-contaminated" equipment, such as a PCB-contaminated transformer
- 500 ppm or more: a "PCB transformer" or other PCB article subject to the strictest requirements
Mineral oil-filled electrical equipment with no test data is generally assumed to be PCB-contaminated, and transformers with no nameplate or test data may be assumed to be PCB transformers.
Who Must Comply?
Part 761 applies to anyone who owns, uses, stores, transports or disposes of PCBs or PCB items, including electric utilities, manufacturers, building owners, schools and contractors who remove PCB equipment or building materials. Commercial storers, transporters and disposers of PCB waste have additional notification, approval and reporting obligations.
Key Requirements
PCB transformers (761.30(a))
- Inspections: each PCB transformer in use or stored for reuse must be visually inspected for leaks at least once every 3 months. The interval may be extended to once every 12 months if the transformer has impervious, undrained secondary containment for 100 percent of its fluid, or if it contains less than 60,000 ppm PCBs.
- Leaks: cleanup must begin as soon as possible and no later than 48 hours after discovery, and active leaks must be contained and checked daily until repaired.
- Records: inspection and maintenance records must be kept for at least 3 years after the transformer is disposed of.
- Registration: PCB transformers had to be registered with EPA by December 28, 1998, and newly identified ones within 30 days. Transformers in or near commercial buildings must also be registered with the building owner.
- Combustibles: paints, solvents, plastics, paper and similar materials may not be stored within a transformer enclosure or within 5 meters of it.
- Fires: fire-related incidents involving PCB transformers must be reported immediately to the National Response Center.
Marking (Subpart C)
PCB transformers, PCB containers, PCB storage areas, large capacitors and vehicles transporting regulated quantities of PCBs must carry the PCB mark described in 761.45, which identifies the item as containing PCBs and gives disposal information. PCB-contaminated items in the 50 to 499 ppm range generally do not need the mark, though many owners label them anyway.
Storage for disposal (761.65)
- One-year limit: PCB waste must be disposed of within one year of the date it was removed from service for disposal. A one-year extension is available by written notice to EPA in limited circumstances.
- 30-day temporary storage: certain PCB items may be held for up to 30 days from removal from service in an area that does not meet full storage standards, if the removal date is marked on the item.
- Storage area standards: a roof and walls, a floor with continuous curbing at least 6 inches high, containment of at least two times the internal volume of the largest article or 25 percent of the total volume stored, whichever is greater, no drains or other openings, a smooth impervious surface, and location above the 100-year flood elevation.
- Inspections and dating: stored items must be dated when removed from service and checked for leaks at least every 30 days.
Disposal and manifests
PCB liquids and articles at regulated concentrations must go to TSCA-approved incinerators, chemical waste landfills or alternate disposal facilities, depending on the material. Off-site shipments of PCB waste require a manifest, and the disposal facility must send a certificate of disposal. Generators that store PCB waste on site generally must notify EPA and obtain an EPA identification number.
Annual records and document log (761.180)
A facility that uses or stores at one time at least 45 kilograms (99.4 pounds) of PCBs in containers, one or more PCB transformers, or 50 or more PCB large capacitors must prepare a written annual document log by July 1 covering the previous calendar year. The records include manifests, certificates of disposal, inspection and cleanup records, and quantities remaining in service, and must be kept for at least 3 years after the facility stops using or storing PCBs in those quantities.
Spill Cleanup
The PCB Spill Cleanup Policy in 761.120 through 761.135 applies to spills of 50 ppm or more that occurred after May 4, 1987. Spills into surface water, sewers, drinking water, grazing lands or vegetable gardens, and spills of more than 10 pounds of PCBs, must be reported to EPA within 24 hours. Low-concentration spills of less than one pound must be cleaned up within 48 hours. Larger and high-concentration spills require immediate actions within 24 hours, including cordoning off the area and starting cleanup, and must meet cleanup standards such as 10 micrograms per 100 square centimeters on indoor surfaces and 10 ppm in soil in nonrestricted areas, or 25 ppm in soil in restricted access areas. Cleanup records must be kept for 5 years. Spills may also trigger CERCLA reporting to the National Response Center.
Fluorescent Light Ballasts and Building Materials
Fluorescent light ballasts made before 1979 may contain small PCB capacitors, while ballasts made later are typically marked "No PCBs." Leaking PCB ballasts must be handled as PCB waste, and EPA encourages removing older ballasts, especially in schools. PCBs may also be found in caulk, paint and other building materials in buildings constructed or renovated between about 1950 and 1979. These materials are PCB bulk product waste when removed and have their own disposal options. State rules may be stricter.
Penalties and Enforcement
EPA enforces Part 761 under TSCA, and TSCA civil penalties are adjusted annually for inflation. Knowing or willful violations can bring criminal penalties. Common findings include missing transformer inspection records, overdue PCB waste beyond the one-year storage limit, missing PCB marks, incomplete annual document logs and improper disposal of ballasts and building materials.
Common Compliance Mistakes
- Not knowing which transformers and capacitors contain PCBs
- Skipping quarterly transformer inspections or not recording them
- Holding PCB waste past the one-year disposal deadline
- Storing combustible materials near PCB transformers
- Throwing out old ballasts without checking for PCBs
- Missing the July 1 annual document log
How to Comply: Step by Step
- Inventory equipment. Identify transformers, capacitors, ballasts and other equipment that may contain PCBs, using nameplates and test data.
- Test when unsure. Sample oil or materials to confirm concentrations instead of guessing.
- Mark and register. Apply PCB marks where required and confirm transformer registrations.
- Inspect on schedule. Set quarterly or annual transformer inspections and 30-day storage area checks.
- Manage waste. Date items removed from service, store them properly and ship them for disposal within one year.
- Prepare for spills. Keep spill response procedures and supplies near PCB equipment.
- Complete annual records. Prepare the document log by July 1 and retain records.

Frequently Asked Questions
At what concentration are PCBs regulated?
Most Part 761 requirements apply at 50 ppm or more. Equipment with 50 to 499 ppm is PCB-contaminated, and 500 ppm or more is a PCB transformer or PCB article with stricter rules.
How long can PCB waste be stored?
PCB waste must be disposed of within one year of being removed from service for disposal. Some items may be kept in temporary storage for up to 30 days before moving to a compliant storage area.
How often must PCB transformers be inspected?
At least once every 3 months, or once every 12 months if the transformer has full secondary containment or contains less than 60,000 ppm PCBs.
Who must prepare an annual PCB document log?
Facilities that use or store at least 45 kilograms of PCBs in containers, one or more PCB transformers, or 50 or more PCB large capacitors. The log is due by July 1 for the previous year.
