Blackstone prepared air quality construction permit applications for emission sources associated with a new cement terminal proposed in Altoona, Iowa. The proposed facility consisted of a cement storage dome, four storage silos, train and truck material unloading, and truck loadouts. Blackstone was provided the engineering plans and vendor quote documentation for the new facility and utilized that information to determine emission sources and emission points.
After determining all new emission points, Blackstone developed an emissions inventory, including potential and actual emissions, for each emissions point. The potential emissions for the project and each point did not exceed the significant emission rates and modeling was not required. In addition, Blackstone communicated with the Polk County Air Quality Division (AQD) local contact during the application process. Polk County AQD provided draft permits and Blackstone reviewed and provided comments back to the agency prior to permit issuance.
