In Sacramento County, residential wood burning accounts for approximately one-third of wintertime particles. To reduce PM2.5 levels, the Sacramento Metropolitan Air Quality Management District (SMAQMD) established a wintertime residential wood burning curtailment program that restricts burning based on air quality forecasts provided by STI. SMAQMD used these forecasts to provide the public with daily burn status, including periods when burning is prohibited.
STI's evaluation of the benefits of the Check Before You Burn Program indicated
  • On average, the daily 24-hour average particulate matter concentrations were reduced by 12 μg/m3
  • The program reduced the number of days exceeding National Ambient Air Quality Standards by about 40%
  • Wood burning controls in urban Sacramento are an effective control program to reduce PM2.5 concentrations
