AN ACT Relating to increasing performance standards for solid fuel burning devices; and amending RCW 70.94.473.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:

        Sec. 1.  Section 6, chapter 405, Laws of 1987 and RCW 70.94.473 are each amended to read as follows:

          Any person in a residence or commercial establishment which has an adequate source of heat without burning wood shall:

          (1) Not burn wood in any solid fuel heating device whenever the department has determined under RCW 70.94.715 that any air pollution episode exists in that area;

          (2) Not burn wood in any solid fuel heating device, except wood stoves which meet the standards set forth in RCW 70.94.457, in the geographical area and for the period of time that impaired air quality has been determined, by the department or any authority, for that area.  For the purposes of this section, impaired air quality shall mean air contaminant concentrations nearing unhealthful levels concurrent with meteorological conditions that are conducive to an accumulation of air contamination.  If, after July 1, ((1990)) 1991, the department determines that there is quantitative evidence that wood stoves meeting the requirements of RCW 70.94.457 are contributing to impaired air quality, the department or any authority may prohibit burning of all solid fuel burning devices as provided by this section including those meeting the requirements of RCW 70.94.457.  However, neither the department nor any authority shall prohibit burning in a solid fuel burning device if the device emits particulate matter at a rate less than 1.5 grams per hour as determined by the department.  The department shall use the testing procedures provided under 40 C.F.R. part 60, as now law or hereafter amended, unless the department finds those procedures to be inappropriate.
