EPA Greenlights Connecticut's Air Pollution Controls for Gas Station
Published Date: 3/13/2026
Proposed Rule
Summary
The EPA wants to approve Connecticut’s plan update that includes new pollution controls for Algonquin Gas Transmission’s compressor station in Cromwell to help clean up the air. They also confirmed there are no major pollution issues from rubber tire factories in the state. This means cleaner air for local communities, with public comments open until April 13, 2026.

Algonquin Cromwell Station Must Cut VOCs
The EPA is proposing to add Connecticut Consent Order No. 8383 (issued December 9, 2024) for Algonquin Gas Transmission’s Cromwell compressor station into the Connecticut State Implementation Plan. The Order requires controls such as dry seals on all centrifugal compressors, quarterly Method 21 leak detection and repair (LDAR) with optional OGI, monthly audio/visual/olfactory (AVO) inspections, limits on storage-vessel potential-to-emit below 6 tpy (aggregate storage-vessel PTE is 1.16 tpy), and documents that pneumatic controllers at the site have a collective VOC PTE of about 0.5 tpy; EPA says these measures implement RACT for VOCs in the Cromwell facility.
No Rubber Tire Plants in Connecticut
Connecticut submitted a negative declaration on May 16, 2025 stating that there are no existing rubber tire manufacturing facilities in the State covered by EPA’s CTG "Control of Volatile Organic Emissions from Manufacture of Pneumatic Rubber Tires" (EPA–450/2-78-030). EPA is proposing to approve Connecticut’s negative declaration, meaning the State has certified it has no sources subject to that CTG.

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.
2026-11047, National Emission Standards for Hazardous Air Pollutants From Hazardous Waste Combustors: Residual Risk and Technology Review
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!
2026-10387, Phasedown of Hydrofluorocarbons: Reconsideration of Certain Regulatory Requirements Promulgated Under the Technology Transitions Provisions of the American Innovation and Manufacturing Act of 2020
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.
