PM control devices can reduce PM emissions by 10–99.9%, Although the emission standards published in 1996 and 2004 allow 3–10 years for existing plants to reduce their PM emission rates, reduction is not likely to be significant in existing plants as there are few measures to enforce the standard.

The use of the current worst case AP-42 emission factor for fines crushing without control (0.0315 lb TSP/ton) indicates that a facility can crush up to 300,000 tons and only emit 4.7 tons of total suspended particulate. These units are powered by diesel-fired generators and a

Use the current equation to determine the emission factor. This information should be consistent with the construction permit.
These wet stone emission factor results are entirely consistent with the zero visible emissions operating conditions observed during all of these tests.
