## Key 2026 EPA Regulatory Rules Enforced
- **15-Pound Threshold (Effective Jan 1, 2026):** Appliances holding >= 15 lbs of HFCs or substitutes with GWP > 53 require mandatory leak rate calculation on every addition, 30-day repair clocks, and 3-year recordkeeping (40 CFR 84.106).
- **2026 Maximum Leak Rate Thresholds:** Comfort Cooling = 10.0% | Commercial Refrigeration = 20.0% | Industrial Process Refrigeration (IPR) = 30.0%.
- **10-Day Verification & 125% Chronic Leaker Rule:** Initial and follow-up verification tests are mandatory within 10 days of repair; appliances receiving >= 125% of full charge in a calendar year require an EPA Chronic Leaker Report by March 1.
