Originally, Section 612 was limited by ozone-depleting chemicals. However, after passing regulations to phase-out R134a, an HFC refrigerant with no ozone-depleting potential, this phase-out was defended by a subsidiary of DuPont siding with the EPA as it was challenged by a major manufacturer of R134a, and was struck down in 2017.
The regulatory program helps to minimize the release of refrigerants, and in particular ozone depleting refrigerants such as chlorofluorocarbons and hydrofluorocarbons, as well as other regulated refrigerants as determined by Section 612. The licensure program complies with the requirements under the Montreal Protocol.
The EPA defines refrigerant reclamation as "Reclaim refrigerant means to reprocess refrigerant to at least the purity specified in appendix A to 40 CFR part 82, subpart F (based on AHRI Standard 700–1993, Specifications for Fluorocarbon and Other Refrigerants) and to verify this purity using the analytical methodology prescribed in appendix A ...
The EPA estimates that between about 6% and 10% of the 66,000 public drinking water systems subject to this rule may have to take action to reduce PFAS to meet these new standards.
Biden’s EPA touted the crackdown on Hart, the first-ever person charged for climate change-related bootlegging of refrigerants — namely, hydrochlorofluorocarbons (HFCs) — without the agency ...
Discover why the EPA targets six PFAS chemicals for new regulations, focusing on their health risks, prevalence, and extensive scientific research.
R-410A was invented and patented by Allied Signal (now Honeywell) in 1991. [5] Other producers around the world have been licensed to manufacture and sell R-410A. [6] R-410A was successfully commercialized in the air conditioning segment by a combined effort of Carrier Corporation, Emerson Climate Technologies, Inc., Copeland Scroll Compressors (a division of Emerson Electric Company), and ...
Two PFAS chemicals have been found there at levels above the new EPA regulations of 4 parts per trillion. One chemical has been as high as 6.1 parts per trillion and the other at 4.7 parts per ...
