2026-06275 — Renewable Fuel Standard (RFS) Program: Standards for 2026 and 2027, Partial Waiver of 2025 Cellulosic Biofuel Volume Requirement, and Other Changes

The EPA just set new rules for renewable fuels in 2026 and 2027, including how much biofuel must be used. They’re also easing the 2025 cellulosic biofuel goals because production fell short and dropping renewable electricity as a qualifying fuel. These changes affect fuel producers and sellers, kick in mostly by mid-2026, and aim to keep America’s fuel cleaner and greener without breaking the bank.

2026-05167 — National Emission Standards for Hazardous Air Pollutants: Ethylene Oxide Emissions Standards for Sterilization Facilities Residual Risk and Technology Review Reconsideration

The EPA is proposing changes to rules for sterilization facilities that use ethylene oxide, a chemical that can be harmful if not controlled. They want to remove some strict risk-based limits, fix technical mistakes, and update how facilities prove they’re following the rules. If you run or work with these facilities, get ready for new deadlines and clearer standards by mid-2026, which could affect how you manage emissions and compliance costs.

2026-04646 — Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Large Municipal Waste Combustors Voluntary Remand Response and Five-Year Review

The EPA is updating pollution rules for big trash-burning plants to cut harmful emissions like lead, mercury, and dioxins. These changes affect both new and existing facilities, tighten limits, remove some loopholes, and improve reporting, all starting May 11, 2026. This update will help clean the air by reducing over 3,200 tons of pollution each year, making communities healthier and safer.

2025-21788 — Oil and Natural Gas Sector Climate Review: Extension of Deadlines in Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources

The EPA is giving oil and natural gas companies more time to meet new pollution control rules and report their emissions. Deadlines for fixing leaks, monitoring equipment, and submitting state plans are pushed back to help everyone get ready without rushing. These changes keep the climate goals on track while easing the financial and timing pressure on the industry.

2025-20402 — Updated Definition of “Waters of the United States”

The EPA and Army Corps are updating the rules that decide which waters are protected under the Clean Water Act, following a 2023 Supreme Court decision. This change helps everyone know exactly which waters are covered, making it easier to protect lakes, rivers, and wetlands while respecting state and tribal rights. People and businesses affected should share their thoughts by January 5, 2026, as this update could impact water projects and environmental protections.

2025-19882 — Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) Data Reporting and Recordkeeping Under the Toxic Substances Control Act (TSCA); Revision to Regulation

The EPA is updating rules for companies that make or import PFAS chemicals, asking them to report certain info about these substances from 2011-2022. The changes add some smart exceptions to ease reporting on things companies probably don’t know, saving time and hassle. Comments on the proposal are open until late December 2025, so affected businesses should get ready to weigh in!

Previous: 2026-05640 — Privacy Act of 1974; System of Records

The EPA is officially retiring its old grants record system called IGMS/NGGS because it no longer uses personal info to find records. This change affects anyone interested in how the EPA handles grant data and means the system stopped being active in July 2024. If you want to share your thoughts, you’ve got until April 22, 2026, to speak up—no money changes here, just cleaner data rules!
