The Puget Sound Clean Air Agency is providing public notice for a proposed permit and public hearing for Cadman Materials to replace a drum dryer and burner, substantially alter an existing baghouse, and replace passive condensers on two asphaltic cement storage tanks. The replacement of the condensers makes the contents of the asphaltic cement storage tanks into review. The substantial alteration of the baghouse makes the truck loading scavenger duct and the flight conveyors to the existing asphaltic concrete storage silos into review. Emissions from the pugmill are not under review as part of this project. This Notice of Construction is the result of an enforcement action because all the proposed changes were carried out prior to submitting the application. This Notice of Construction includes only the equipment listed above. Emissions due to the project are particulate matter of 4.0 tons per year (TPY), particulate matter of less then 2.5 micrometers in diameter 3.7 TPY, sulfur dioxide of 0.5 TPY, nitrogen oxides of 10.0 TPY, volatile organic compounds of 2.1 TPY, carbon monoxide of 59.2 TPY, combined hazardous air pollutants (HAP) of 0.8 TPY, and maximum individual HAP of 0.3 TPY.
