This means Wyoming will handle coal ash rules instead of the federal government, making things smoother for local businesses and communities. If you’re involved with coal ash in Wyoming, get ready for some fresh rules and oversight that keep the environment safer without slowing down progress. ## Abstract The Environmental Protection Agency (EPA or the Agency) is approving the Wyoming partial coal combustion residuals (CCR) permit program under the Resource Conservation and Recovery Act (RCRA). After reviewing the CCR permit program application submitted by the Wyoming Department of Environmental Quality (WDEQ), EPA has determined that Wyoming's partial CCR permit program meets the standard for approval under RCRA. Wyoming's partial CCR permit program will operate in lieu of the Federal CCR program, with the exception of the specific provisions noted below. ## Effects PRIA read - Wyoming Takes Over Coal Ash Permitting: benefit, medium. EPA approved Wyoming's partial coal combustion residuals (CCR) permit program and it will operate in lieu of the Federal CCR permit program (except for specific provisions) starting March 30, 2026. If you own or run a coal-ash unit in Wyoming, state permits and state oversight will now be the main… - Permits Replace Federal Rules (Permit Shield): benefit, medium. Once Wyoming issues a final CCR permit for a unit, the permit terms apply in place of the corresponding Federal CCR requirements and provide a permit shield against direct enforcement of those Federal rules. The permit becomes the enforceable document for the permittee. - Some Federal Rules Still Apply: cost, medium. Wyoming's approval is partial: Federal CCR provisions that Wyoming did not seek approval for will continue to apply directly to CCR units in Wyoming. EPA noted additional provisions tied to the 2024 Legacy Rule remain federal obligations for affected units. - Permit Timing and 30-Year Post-Closure Rule: cost, high. Wyoming requires owners/operators to obtain permits for all existing and new CCR units and sets permit durations for operating life through post-closure; closure permits include a minimum 30-year post-closure term. Existing landfills must apply for renewal at least 12 months before permit expiratio… - Public Notice and Two Comment Periods: benefit, low. Permit applicants must provide public notice and two 30-day comment periods: one after the application is deemed complete and another when a proposed permit is issued. Notices must be published for two consecutive weeks and sent to landowners within one-half mile, local officials within 50 miles, a… - State Enforcement and Penalties: cost, high. WDEQ has enforcement authority including inspections, investigations, injunctions, and civil penalties for violations of the Act or permits. Penalties may be assessed up to $10,000 for each violation for each day the violation continues. - State Inspection and Information Access: cost, medium. Under Wyoming law, WDEQ may inspect CCR facilities, copy records, inspect monitoring equipment, and require applicants to provide access authorization before a permit is issued. WDEQ must notify applicants within 60 days whether an application is complete and completes technical review within 90 da… ## Related documents - [2026-19071](https://policyrisk.com/federal-register/2026-19071): Partial Repeal of the Carbon Pollution Standards for Fossil Fuel-Fired Electric Generating Units, 2026-09-17 - [2026-19072](https://policyrisk.com/federal-register/2026-19072): Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emiss…, 2026-09-17 - [2026-18317](https://policyrisk.com/federal-register/2026-18317): Updated Definition of “Waters of the United States”, 2026-09-09 - [2026-14112](https://policyrisk.com/federal-register/2026-14112): Amendments and Nonconformance Penalties for Model Year 2027 and Later Heavy-Duty Highway Engines and Amendments to Inducement Provisions fo…, 2026-07-14 - [2026-13667](https://policyrisk.com/federal-register/2026-13667): Minor New Source Review Program Air Permitting Public Participation Requirements for State Implementation Plans, 2026-07-07 - [2026-13263](https://policyrisk.com/federal-register/2026-13263): Revisions To Establish the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) for Public Water Systems, 2026-07-01 ## Sources - [2026-03820 on federalregister.gov](https://www.federalregister.gov/documents/2026/02/26/2026-03820/wyoming-approval-of-state-coal-combustion-residuals-permit-program) - [2026-03820 as published (PDF)](https://www.govinfo.gov/content/pkg/FR-2026-02-26/pdf/2026-03820.pdf) ## Related - [Previous: 2026-03799, Airworthiness Directives; Aerospace & Defense Oxygen Systems SaS (Part of Safra…](https://policyrisk.com/federal-register/2026-03799) - [Next: 2026-03844, Delegations of Authority](https://policyrisk.com/federal-register/2026-03844) - [All Federal Register documents](https://policyrisk.com/federal-register) Source: PRIA, https://policyrisk.com/federal-register/2026-03820 (as of 2026-06-11).
