Oklahoma Gets Pass on Incinerator Rules Because None Exist
Published Date: 6/26/2026
Rule
Summary
The EPA is officially accepting Oklahoma’s statement that no existing waste incinerators covered by certain air pollution rules are operating in the state. This means Oklahoma doesn’t need to enforce these specific pollution controls right now. The rule kicks in on July 27, 2026, with no new costs or changes for businesses since no affected incinerators exist.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Large Municipal Waste Combustors Face Stricter Limits
EPA finalized revised Large Municipal Waste Combustor (LMWC) standards effective May 11, 2026, that set more stringent emission limits (including for cadmium, lead, PM2.5, dioxins/furans, HCl, and SO2). The rule estimates a reduction of 3,269 tons per year from existing sources, and State plans to implement the revised LMWC Emission Guidelines are due March 10, 2027—meaning facilities meeting LMWC applicability (e.g., Reworld) will face the tighter limits and related compliance requirements.
Oklahoma's No‑Incinerator Certification Accepted
The EPA accepted Oklahoma’s negative declarations that there are no existing incinerators subject to the OSWI, HMIWI, and CISWI Emission Guidelines (letters dated August 10, 2020; April 1, 2020; and September 13, 2024). Because Oklahoma certified no applicable sources, the State is exempted from submitting State plans for those EGs and the rule takes effect July 27, 2026, with no new costs or changes for businesses related to those EGs.
Tribal Areas Covered but No Tribal Costs
The EPA’s acceptance of Oklahoma’s negative declarations applies statewide, including certain areas of Indian country (excluding specified excluded lands). EPA states this action will not impose substantial direct compliance costs on federally recognized tribal governments because no applicable incinerators exist.

2026-22082, Additional Reconsideration Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review
The EPA is updating rules for oil and natural gas companies to fix issues from last year’s changes. They’re scrapping the Super Emitter Program, splitting well sites into clearer groups, and tweaking rules on leaks, equipment, and inspections. Companies should get ready to comment by December 16, 2026, as these updates could affect how they manage emissions and operate equipment.
2026-21155, Renewable Fuel Standard (RFS) Program: Reallocation of Additional 2025 Small Refinery Exemptions
The EPA is updating how it handles small refinery exemptions (SREs) for 2025 under the Renewable Fuel Standard. They’re deciding whether to spread the extra exemptions between 2026 and 2027 or give them all to 2027. This change might also push back the 2026 compliance deadline, affecting refiners and renewable fuel producers with potential timing and cost impacts.
2026-20849, Clean Water Act Hazardous Substance Facility Response Plans: Compliance Date Delay and Changes To Reflect Administration Policy
The EPA is giving facilities more time to meet new Clean Water Act rules for handling hazardous spills, pushing back the deadline to help them get ready. They’re also removing mentions of climate change and environmental justice to match new government policies. This delay helps facilities plan better without rushing and lets the EPA rethink the rules if needed.
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.
