Washington State HFC Rules Still Apply Despite EPA R-410A Extension (opens the original)
Read excerpt
With the EPA’s recent changes to the federal Technology Transitions (TT) rule creating questions about the continued use of certain high-GWP refrigerants and equipment, Washington state officials are reminding building owners, operators, and contractors that the state’s requirements remain unchanged. During a recent webinar, Laura Kimmel, compliance team lead for the Washington State Department of Ecology’s Refrigerant Management Program (RMP), outlined the state’s HFC rule, explaining its requi
1994: Mandatory Certification Begins (opens the original)
Read excerpt
The Clean Air Act Amendments (CAA) of 1990 ushered in mandatory EPA certification for HVACR technicians.
