The Puget Sound Clean Air Agency (the Agency) is publishing a public notice for a proposed permit for Cadman Materials. The proposed project is to replace the existing pug mill mixer and rotary dryer at the North Everett asphalt plant with a new drum mixer. Cadman is also proposing to increase the use of recycled asphalt pavement (RAP) at the facility and to add the ability to use recycled asphalt shingles (RAS), which requires the installation of new RAP and RAS feeding equipment. This notice is published pursuant to WAC 173-400-091, WAC 173-400-171(3)(k), and WAC 173-460-071(2). As part of this action, Cadman Materials requested a voluntarily limit on facility-wide emissions. Cadman Materials has requested an annual emission limit of 99 tons of carbon monoxide (CO). The proposed Order would provide Cadman Materials with a federally enforceable emission limit formally establishing it as a minor or area source of air pollution. In addition, Cadman Materials has proposed removing the existing pug mill mixer and rotary dryer to offset emissions of toxic air pollutants (TAP) from the new drum mixer.
The new drum mixer will be a source of particulate matter (PM), volatile organic compounds (VOC), nitrogen oxides (NOx), carbon monoxide (CO), sulfur dioxide (SO2), hazardous air pollutants (HAP), and TAP. Since the new drum mixer will replace the existing pug mill mixer and rotary dryer, annual emissions of these pollutants are not expected increase as a result of this proposal. The estimated potential emissions from the new drum mixer are 33.18 ton/year PM, 21.14 ton/year PM10, 19.59 ton/year PM2.5, 22.26 ton/year NOx, 99 ton/year CO, 5.60 ton/year VOC, 0.60 ton/year SO2, and 0.95 ton/year HAP. In addition, the estimated potential emissions from the new RAP and RAS feeding equipment and storage piles are 1.60 ton/year PM, 0.75 ton/year PM10, and 0.11 ton/year PM2.5.
