EPA nods to Connecticut's gas compressor ozone fixes.
Published Date: 8/6/2026
Rule
Summary
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut to address certain Federal requirements for the 2008 and 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS) under the Clean Air Act (CAA). This revision approves a source-specific SIP revision for Algonquin Gas Transmission, LLC's Cromwell compressor station facility in Cromwell, CT, to address reasonably available control technology (RACT) determinations for major stationary sources of volatile organic compounds (VOC). The CAA requires states to submit SIP revisions addressing RACT requirements for ozone nonattainment areas classified as Moderate or higher and for any portion of the state located in an ozone transport region (OTR). RACT determinations are required for this source because it is located in the New York-Northern New Jersey-Long Island, NY-NJ-CT 2008 ozone Severe nonattainment area and 2015 ozone Serious nonattainment area and because Connecticut is in the OTR. The EPA is also approving a negative declaration for existing rubber tire manufacturing sources statewide. This action is being taken in accordance with the Clean Air Act.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 1 costs, 1 mixed.
Algonquin Cromwell Facility RACT Order
The EPA approved Consent Order No. 8383 (dated December 9, 2024) into Connecticut's State Implementation Plan for the Algonquin Gas Transmission, LLC Cromwell compressor station at 252 Shunpike Road, Cromwell, CT. This adds emission standards that Connecticut determined satisfy reasonably available control technology (RACT) for volatile organic compounds because the source is in the NY-NJ-CT 2008 ozone Severe nonattainment area and the 2015 ozone Serious nonattainment area and Connecticut is in the ozone transport region. The Consent Order becomes federally enforceable as part of the SIP as of the rule's effective date, September 8, 2026.
Rubber Tire Manufacturing Negative Declaration
The EPA approved Connecticut's negative declaration for Control Techniques Guidelines for manufacture of pneumatic rubber tires, submitted with a state submittal dated May 16, 2025, and approved in this rulemaking (published August 6, 2026) and effective September 8, 2026. The negative declaration records that there are no existing rubber tire manufacturing sources operating in Connecticut, and Connecticut regulations (RCSA section 22a-174-20(u)) remain in place should such a source begin operating in the future.

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.

Previous: 2026-15984, Alaska: Final Authorization of State Hazardous Waste Program
The State of Alaska (Alaska or the State) has applied to the United States Environmental Protection Agency (the EPA or the Agency) for final authorization of its hazardous waste program under the Resource Conservation and Recovery Act, as amended (RCRA). The EPA has reviewed Alaska's application and has made a final determination that Alaska's hazardous waste program satisfies all requirements for final authorization. Thus, the EPA is granting final authorization for the State to operate its program subject to the limitations on its authority retained by the EPA in accordance with RCRA, including the Hazardous and Solid Waste Amendments of 1984 (HSWA). Alaska's program will operate in lieu of the Federal hazardous waste program in Alaska; however, the EPA will retain jurisdiction and authority to implement the Federal RCRA program in Indian country and areas of exclusive Federal jurisdiction in Alaska.
