§ 25-7-106.3. Commission - duties - wood-burning stoves - episodic no-burn days - rules

(1) The commission shall promulgate, no later than March 1, 1990, such combination of regulations as it may find to be cost-effective and consistent with the legislative declaration set forth in section 25-7-102 in order to establish limitations on the use of wood-burning stoves and fireplaces during those periods of time declared by the Colorado department of health to be a high pollution day. The department may declare a high pollution day based on experienced or anticipated excessive levels of carbon monoxide or particulates when air pollution standards are exceeded for particulates, carbon monoxide, or visibility. The limitations on the use of wood-burning stoves and fireplaces imposed pursuant to this section may include no-burn days, and such no-burn days shall be specific to the separate airsheds within the Denver-Boulder metropolitan area. Such limitations shall be applicable only in those portions of the counties of Adams, Arapahoe, Boulder, Denver, Douglas, and Jefferson which are located in the AIR program area, as such area is defined in section 42-4-304 (20), C.R.S. Such regulations shall exclude areas above seven thousand feet unless the commission determines that particulates from wood burning in such areas are contributing to the brown cloud. Such regulations shall not apply to any person who utilizes wood-burning stoves or fireplaces as the primary source of heat in such person's place of residence. Such regulations shall permit exemptions for wood-burning stoves that meet Phase III emissions standards. For the purposes of this section, "Phase III" means wood stove standards adopted by the commission which are more strict than existing wood stove standards. The regulations promulgated pursuant to this subsection (1) shall not be effective until July 1, 1990.

(2) No regulation promulgated by the commission pursuant to subsection (1) of this section shall apply within any municipality which has in effect on January 1, 1990, an ordinance mandating restricted use of wood-burning stoves and fireplaces during those periods of time declared by the Colorado department of health to be high pollution days.
