Virginia Pollutes Past Limit, EPA Posts the Spreadsheet Shame
Published Date: 8/4/2026
Notice
Summary
The U.S. Environmental Protection Agency (EPA) is providing notice of the availability of data on the administration of the assurance provisions of the Cross-State Air Pollution Rule (CSAPR) trading program for the 2025 control period. Virginia units participating in the CSAPR NO<INF>X</INF> Ozone Season Group 2E Trading Program during the 2025 control period reported total nitrogen oxides (NO<INF>X</INF>) emissions that exceeded the State's assurance level under the program. The EPA has posted on the Agency's website a spreadsheet that presents data demonstrating the exceedance and the Agency's preliminary calculations of the additional allowances that owners and operators of certain Virginia units must surrender. The EPA will consider timely objections to the data and calculations before making final determinations of the additional allowances that owners and operators of certain Virginia units must surrender.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
Virginia Must Surrender 140 Allowances
Virginia power units reported 70 tons of NOX emissions over the State's assurance level for the 2025 control period. That exceedance requires owners and operators in Virginia to surrender 140 additional CSAPR NOX Ozone Season Group 2E allowances, with final calculations due by 2026-10-01 and the required allowances held in an assurance account by 2026-11-01.
Allowance Burden Assigned to Specific Operators
EPA's preliminary calculations apportion the 140 additional allowances primarily to the group of units operated by Hopewell Power Generation, LLC and Dominion Generation, with smaller shares apportioned to groups operated by Wolf Hills Energy, LLC and Calpine Operating Services Company, Inc. EPA will consider timely objections to these calculations before issuing final apportionments.

2026-19071, Partial Repeal of the Carbon Pollution Standards for Fossil Fuel-Fired Electric Generating Units
The EPA is rolling back most of the 2024 rules that limited carbon pollution from fossil fuel power plants. This change affects coal and gas plants by easing some strict limits on emissions and carbon capture technology. The new rules kick in on November 16, 2026, potentially saving money for power plants but raising questions about pollution control.
2026-19072, Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under Clean Air Act Section 111
The EPA is proposing to cancel all greenhouse gas rules for fossil fuel power plants, saying the law doesn’t let them regulate these emissions for climate reasons. This change affects power plants across the U.S. and could impact future pollution limits and costs. Comments on this proposal are open until November 2, 2026, so now’s the time to speak up!
2026-18317, Updated Definition of “Waters of the United States”
The purpose of this supplemental notice of proposed rulemaking is for the U.S. Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") to supplement and seek additional comment on certain aspects of an earlier proposal, published on November 20, 2025, to revise the regulations defining the scope of waters federally covered under the Clean Water Act in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. As stated in the agencies' November 20, 2025 Notice of Proposed Rulemaking (NPRM), the agencies intend for this rulemaking to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." After consideration of the public comments received on the NPRM, the agencies are issuing this notice to supplement the NPRM with additional regulatory options on certain aspects of the proposed rule.
2026-14112, Amendments and Nonconformance Penalties for Model Year 2027 and Later Heavy-Duty Highway Engines and Amendments to Inducement Provisions for SCR-Equipped Diesel Engines
Starting with model year 2027, the EPA is updating rules for big truck engines to make sure they last longer and pollute less. They’re also letting engine makers pay penalties if their engines don’t meet standards, and tightening rules for special pollution-control systems on diesel engines. These changes affect truck and engine makers and kick in soon, with public feedback due by August 29, 2026.
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!
