Residential Wood Smoke Reduction Program


The Residential Wood Smoke Reduction Program and associated District Rule 4901 help reduce particulate matter and carbon monoxide when winter air quality is forecast to deteriorate. Achieving additional emissions reductions from residential wood burning is necessary for the Valley to meet federal PM2.5 health standards and improve public health.

The Residential Wood Smoke Reduction Program is a program that informs Valley residents when they can use a wood-burning device. From November 1 through the end of February, the District issues a daily wood-burning curtailment status for each county, in accordance with the below. It also provides grants for residents to change out their wood burning fireplace or stove with an electric or gas device.

Proper Operation of Wood Burning Fireplace and Heaters

  • Anyone operating a registered wood burning fireplace or heater must ensure there is no visible smoke year-round (except when a fire is started). Startup of a new fire may not exceed 15 consecutive minutes in any consecutive four-hour period.
  • Anyone operating a wood burning fireplace or a wood burning heater must ensure the visible emissions do not exceed 20% opacity for a period or periods aggregating more than three (3) minutes in any one (1) hour.
