Ultrafine Particle Study

Status

The Olympic Clean Air Agency and the University of Washington jointly studied air quality in Jefferson and Clallam Counties. This project evaluated possible air quality changes associated with new biomass co-generation facilities in Port Townsend and Port Angeles and changes in ultra-fine particle concentrations associated with both facilities.
