EPA SNAP (Significant New Alternatives Policy) is the Environmental Protection Agency’s regulatory mechanism for approving substitute refrigerants and controlling phase-down schedules for ozone-depleting and high-global-warming refrigerants. Established in 1994, it remains the primary federal framework for refrigerant transitions. SNAP provides approved alternatives across all HVAC, refrigeration, and foam-blowing applications.
Regulatory Authority
SNAP operates under Clean Air Act Section 612. EPA maintains official lists of approved and prohibited substitutes for each application. Manufacturers and distributors must ensure products comply with current SNAP regulations before sale. The program includes mandatory phase-out dates and production quotas for restricted substances.
Practical Implementation
HVAC contractors reference EPA SNAP tables when selecting refrigerants for new installations, retrofits, and service. Current guidance prioritizes HFO refrigerants with GWP below 150 for new systems. Compliance ensures equipment meets federal standards, qualifies for incentives, and avoids penalties. EPA updates SNAP rules annually, reflecting technological progress and climate policy evolution.
