Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

Amendments to Rule 4901 satisfy control measure commitments included in the District's 2012 PM2.5 Plan. 

Rule 4901 implemented a tiered episodic wood burning curtailment program, a registration program for clean 

qualifiying devices, and a registration program for qualified professionals to be Wood Burning Heater 

Profesionals. Details of the adopted changes are in the final staff report. 

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

VI. IMPACT ON AIR QUALITY PLAN 

 No Impact Impacts RFP Impacts attainment 

Discussion: Amendments to Rule 4901 will reduce 5.1 tons per day of directly emitted PM2.5 emissions from the 

residential wood burning source category during the wood burning season (November through February). See calculation 

summaries below: 

• Lowering curtailment threshold from 30 to 20 μg/m3 

– 3.33 tons/day of reductions from high polluting devices 

– 0.065 tons/day increase in emissions from registered devices when PM2.5 concentrations are forecast to be 30 to 65 

μg/m3 

• 24% transition of old dirtier wood burning heaters and fireplaces to cleaner devices 

– 2.04 tons/day of reductions from the transition 

– 0.22 tons/day increase in emissions from newly registered devices when PM2.5 concentrations are forecast to be 20 to 

65 μg/m3 

TOTAL EMISSION REDUCTIONS: 5.1 tpd PM2.5
