EPA Reconsiders HFC Rules for Refrigeration and Cooling Tech
Published Date: 10/3/2025
Proposed Rule
Summary
The EPA is updating rules to help companies using certain hydrofluorocarbons (HFCs) in cooling and refrigeration gear, like supermarket fridges and air conditioners. They’re letting some older equipment keep running and asking for ideas to fix supply chain problems with a special refrigerant mix. These changes affect businesses now and could save money by easing equipment replacement timing.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 0 costs, 1 mixed.
Older AC/Heat Pump Units Can Still Be Installed
If you buy or install residential or light-commercial air conditioners or heat pumps that were manufactured or imported earlier, the EPA proposes to allow that existing equipment to keep being installed. This change would let some owners and installers delay replacing equipment and may reduce immediate replacement costs.
Multiple Refrigeration Subsectors Under Review
The EPA's proposal responds to petitions and requests from companies in many cooling and refrigeration subsectors, including refrigerated transport (intermodal containers), industrial process refrigeration and chillers for semiconductor manufacturing, retail food refrigeration (remote condensing units and supermarkets), cold storage warehouses, refrigerated laboratory centrifuges and shakers, and condensing units in residential and light commercial air conditioning and heat pumps. Businesses in those listed subsectors may see regulatory changes if the EPA finalizes actions addressing those petitions.
EPA Seeks Input on Refrigerant Blend Supply Issues
The EPA is asking for advance public comment on possible actions to address supply chain problems for a particular refrigerant blend. If you run equipment or a business that depends on that refrigerant blend, the agency is soliciting ideas that could lead to future rules or guidance affecting supply and availability.

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.

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.

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.
