These stacks emit pollutants resulting primarily from raw material handling operations and operation of the tunnel kiln and dryer. Particulate emissions result primarily from storing, crushing, and grinding the raw clay. In this particular facility, the crushing operation is performed with a fine mist of water that minimizes the amount of dust created. The grinding room is enclosed and equipped with a cyclone type dust collection system. However, note that these controls are not considered for PTE calculations.
Units are pounds of pollutant emitted per ton of brick produced.
Again, PTE is based on 71,500 tons of bricks produced per year. Units are pounds of pollutant emitted per ton of brick produced. ND indicates no data given. Neg means negligible. Since the facility has emission controls installed on the crushing and grinding operations, the facility may be able to qualify for a synthetic minor permit, depending on collection efficiency.
