Perchloroethylene (PCE) and Carbon Tetrachloride (CTC); Regulation under the Toxic Substances Control Act (TSCA); Compliance Date Extensions
Published Date: 7/28/2026
Rule
Summary
The U.S. Environmental Protection Agency (EPA or Agency) is finalizing an extension of certain compliance dates applicable to certain entities subject to the risk-management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC) under the Toxic Substances Control Act (TSCA). EPA is extending certain Workplace Chemical Protection Program (WCPP) compliance dates for non-federal owners and operators to match the existing compliance dates for federal agencies and their contractors. For both PCE and CTC, this action extends the compliance date for initial monitoring for inhalation exposure to June 21, 2027, and extends the compliance date to meet the existing chemical exposure limit (ECEL), establish a regulated area, institute a workplace information and training program, provide any required respiratory personal protective equipment (PPE), and establish a respiratory PPE program to September 20, 2027. For PCE, EPA is also extending the compliance date for federal entities to institute a workplace information and training program to September 20, 2027, and for non-federal entities to establish and implement an exposure control plan to December 20, 2027.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
PCE WCPP Compliance Date Extensions
If you own or operate a facility subject to the PCE Workplace Chemical Protection Program (WCPP), EPA moved several non-federal compliance deadlines. Initial monitoring was extended from December 15, 2025 to June 21, 2027; meeting the ECEL, establishing a regulated area, providing required respiratory PPE, and establishing a respiratory PPE program were extended from March 13, 2026 to September 20, 2027; and establishing and implementing an exposure control plan was extended from June 7, 2027 to December 20, 2027. EPA also extended the workplace information and training program requirement for both federal and non-federal entities from March 13, 2026 to September 20, 2027.
CTC WCPP Compliance Date Extensions
If you own or operate a facility subject to the CTC Workplace Chemical Protection Program (WCPP), EPA extended certain non-federal compliance deadlines by roughly 12 months to match federal dates. Initial monitoring was extended from June 11, 2026 to June 21, 2027; meeting the ECEL, establishing a regulated area, providing required respiratory PPE, establishing a respiratory PPE program, and instituting a workplace information and training program were extended from September 9, 2026 to September 20, 2027. EPA did not extend dermal protection compliance dates for CTC.
Dermal Protection Dates Not Extended
EPA is explicitly not extending the WCPP compliance dates that require dermal protection. For both PCE and CTC, the rule states the Agency is not changing the dermal protection compliance timeline included in the original 2024 Final Rules.
Estimated National Cost Savings
EPA estimates that delaying these compliance dates produces annualized cost savings of about $4.78 million to $6.43 million (EPA references similar estimates of $4.05 million annualized and a $57.86 million present value under a different accounting). These savings come from deferring when regulated entities must incur compliance costs.

2026-13667, Minor New Source Review Program Air Permitting Public Participation Requirements for State Implementation Plans
The EPA wants to give states more freedom to decide how much public input is needed when approving small air pollution sources or changes. This means local air agencies can tailor public participation to fit their community’s needs while still protecting air quality. If you’re involved in air permits, watch for comment deadlines and possible virtual hearings this summer!
2026-13263, Revisions To Establish the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) for Public Water Systems
The EPA is rolling out the sixth Unregulated Contaminant Monitoring Rule (UCMR 6) to check for new, sneaky chemicals in public drinking water. Big water systems serving 3,300+ people and some smaller ones will test for 30 different contaminants, including certain PFAS and pesticides, to keep our water safe. Comments and feedback are open until late August 2026, and the EPA will host fun online meetings to chat about the plan!
2026-12927, U.S. Ecology Nevada, Inc. High Mercury Subcategory Wastes Land Disposal Restrictions Variance
The EPA is giving U.S. Ecology Nevada a special green light to handle and dispose of high-mercury waste a bit differently than usual. This means mercury waste treated in Pennsylvania can now be safely sent to U.S. Ecology’s Nevada site for disposal under new rules starting July 27, 2026. This change helps protect people and the environment while keeping mercury waste management efficient and cost-effective.

The EPA just updated rules for places that burn hazardous waste, like incinerators and boilers, to keep the air safe and clean. They confirmed current standards work well but added new limits on harmful gases like hydrogen fluoride and hydrogen cyanide. These changes start June 3, 2026, and include easier electronic reporting and some new rules for startup and shutdown times—helping protect health without big costs.
2026-10641, Hazardous and Solid Waste Management System: Disposal of Coal Combustion Residuals From Electric Utilities; Federal CCR Permit Program; Reopening of Comment Period
The EPA is reopening the comment period until June 29, 2026, for its proposed rule to create a federal permit program for safely disposing of coal ash from power plants. This affects electric utilities that handle coal waste and aims to improve environmental safety while possibly impacting their costs. Now’s the time for everyone to share their thoughts and help shape the rules!

The EPA is updating rules to phase down hydrofluorocarbons (HFCs), chemicals used in cooling systems like refrigerators and air conditioners. These changes affect businesses in refrigeration, supermarkets, semiconductor manufacturing, and more, allowing some older equipment made before 2025 to keep running. The new rules kick in on July 27, 2026, helping industries transition smoothly while cutting harmful emissions.

EPA issued a final rule in the Federal Register of June 30, 2026, establishing tolerances for residues of epyrifenacil (CASRN 353292-31-6) in or on multiple commodities requested by Valent U.S.A. LLC under the Federal Food, Drug, and Cosmetic Act (FFDCA). That document inadvertently issued incorrect tolerances for corn, field (forage, stover); wheat (forage, hay, straw); and soybean (forage, hay). This document corrects that final regulation.

NMFS, upon request from the U.S. Department of the Navy (Navy), issues these regulations pursuant to the Marine Mammal Protection Act (MMPA) to govern the taking of marine mammals incidental to training and testing activities using Surveillance Towed Array Sensor System (SURTASS) Low Frequency Active (LFA) sonar systems in the western and central North Pacific and eastern Indian oceans over the course of 7 years from August 2026 through August 2033. These regulations allow for the issuance of a letter of authorization (LOA) for the incidental take of marine mammals during specified activities and timeframes, prescribe the permissible methods of taking and other means of effecting the least practicable adverse impact on marine mammal species and their habitat, and establish requirements pertaining to the monitoring and reporting of such taking. The Navy's activities are considered military readiness activities pursuant to the MMPA, as amended by the National Defense Authorization Act for Fiscal Year 2004 (2004 NDAA) and the NDAA for Fiscal Year 2019 (2019 NDAA).
