more recent testing, and, therefore, may be more representative of emissions from stone crushing, grinding, and screening. In addition, Section 13.2, Fugitive Dust Sources, includes emission factors for materials handling that may be more representative of materials handling emissions than the emission factors in Tables 11.17-3 and 11.17-4 ...
Tests at three sand and gravel plants in California have sponsored tests to compile crystalline silica emission factors for particulate matter (PM) of aerodynamic diameter of 4 µm or less (PM4) and ambient concentration data, indicating that PM4 crystallinesilica emissions range from 0.000006 to 0.000110 lb/t for screening operations, tertiary crushers, and conveyor …

11.24.2 Process Emissions7-9 Particulate matter emissions result from metallic mineral plant operations such as crushing and dry grinding ore, drying concentrates, storing and reclaiming ores and concentrates from storage bins, transferring materials, and loading final products for shipment. Particulate matter emission factors are
Emission Factor Policy Decisions . The standardized PM10 emission factors specified above are based on the controlled and uncontrolled crushing values listed in Table 11.19.2- 2 of Section 11.19.2 of AP -42 (1/95). The TSP factor was derived using the ratio of particulate size multipliers in 13.2.4 of AP-42 (1/95) and the PM10 factors;
Standardized PM10 emission factors were assigned to each classification based on the expected annual average particle size distributions and moisture contents. Predetermined …
Wake Stone Corporation sponsored this emission test program in order to determine PM10 emission factors applicable to transfer points at stone crushing plants. A Quasi-stack system was used to conduct emission tests on the transfer point. Small enclosures were installed at both the inlet and outlet of the

There are very limited total particulate matter data for sand and gravel operations. In the case of stone crushing plants, EPA5 has recommended the use of a multiplying factor of 2.1 to convert from the available PM10 data to corresponding total particulate matter data. A similar approach can be taken for sand and gravel operations.
