The emission factors in Tables 11.24-1 and 11.24-2 are for the process operations as a whole. At most metallic mineral processing plants, each process operation requires several types of equipment. A single crushing operation likely includes a hopper or ore dump, screen(s), crusher, surge bin, apron feeder, and conveyor belt transfer points.

Emission points following these process activities such as secondary and tertiary crusher and screen and recirculating conveyors would be controlled by a baghouse collector. …

Particulate matter emission limit is 0.022 grains per dry standard cubic foot, or gr/ dscf. Opacity limit is seven percent for stack visible emissions. Opacity limit is 10% (15% for crushers) for fugitive visible emissions. Emission limits for affected facilities manufactured on or after April 22, 2008, are:

Atmospheric Pollution Research. Dust emission from crushing of hard rock aggregates. During secondary crushing, the background concentrations were achieved at a 350 m distance for coarse particles. Dust concentrations in the limestone quarry were half of that measured in quarries processing granitic rock material.

1. The rock crusher plant has emission points with mechanically induced air flow, such as a fan forcing emission to a stack or control device, unless approved in writing by the Department. The modeling characterized the rock crusher as a fugitive emission source. The emissions associated with a mechanically induced airflow design would be released

The owner or operator of the affected facility may establish a different baghouse-specific success level for the visible emissions test (other than no visible emissions) by conducting a PM performance test according to § 60.675(b) simultaneously with a Method 22 (40 CFR part 60, appendix A-7) to determine what constitutes normal visible ...
