Air Pollution Control District
The Air Pollution Control District (APCD) enforces the Clean Air Act and other laws and regulations that make the air clean and safe in Louisville/Jefferson County. We also work with the community on policies and programs that lead to a healthier and more sustainable city.
U.S. EPA Proposed Rule to Reduce HFC-23 – “Phasedown of Hydrofluorocarbons,” which includes HFC-23. You can find the proposed rule and other information at https://www.epa.gov/climate-hfcs-reduction/proposed-rule-phasedown-hydrofluorocarbons-establishing-allowance-allocation.
HFCs or “hydrofluorocarbons are potent greenhouse gases that were intentionally developed as replacements for ozone-depleting substances. They are used in refrigeration, air conditioning, aerosols, fire suppression, and foam blowing applications. With the phase out of ozone-depleting substances and the increasing use of refrigeration and air-conditioning globally, use of HFCs has been increasing." So, EPA is proposing to phase down listed HFCs to 15% of their baseline levels by 2036 using an allowance trading system. The proposed rule also limits how much HFC-23 a facility can emit to the environment. HFC-23 is emitted in Louisville by Chemours. If finalized, the proposed rule will reduce Chemours’ emissions of HFC-23 here in Louisville. Chemours has voluntarily committed to further reduce its emissions of HFC-23 by 99% by the end of 2022. Comments on the proposed rule, including environmental justice concerns, must be submitted to U.S. EPA by July 6, 2021.
