activity emissions (lb/ton) and wind erosion emissions (lb/acre). If you want to continue using SCC number with the default Particulate Matter, or PM 10 emission factor of lb/ton for all storage pile emissions, it is not necessary to complete all the information on Form for block 1, storage pile information.
various particle sizes. These collection efficiencies were used along with emission factors for aggregate handling processes (Section of AP42) to calculate particle size distributions. The aggregate handling process emission factors for various particle sizes depend uponthe particle size multiplier.
Please Note: The use of any emission factor on or derived from this web page is at the discretion the local air district were the factors will be used. Therefore it is highly recommended that before any emission factor is utilized that the local air district be consulted. District Emission Factors.
the aggregate tool. Another contributing factor to the discrepancy is the methods of calculating emissions from conveyor belts associated with crushers and screens. As per DAQ policy, the emissions from these conveyors are included with the emission factors used to .

Pits and Quarries Guidance documents The purpose of this document is to clarify the reporting requirements for the Pits and Quarries sector and describe some of the available tools available to estimate NPRI substances releases from major pits and quarries operations.
Emissions of PM, PM10, and occur from a number of operations in stone quarrying and processing. A substantial portion of these emissions consists of heavy particles that may settle out within the plant. As in other operations, crushed stone emission sources may be categorized as either process sources or fugitive dust sources.
drilling PM10 emission factor is based on information published in Section of AP42 (1/95) for crushed stone processing operations. The blasting procedure is based on an emission estimation technique provided in Section of AP42 (Reformatted 1/95) for coal or overburden. A PM10 fraction of 52% is assumed for blasting emissions.
Develop UserDefined Emissions Factors [This function is under development and is not available at this time.] You can develop an emissions factor from individual performance test values that you select from the WebFIRE database using the same procedures that the EPA follows to develop new or revise existing emissions factors.
Oct 22, 2013· PM profile, PM343, was developed based on cement production tests conducted on a cement kiln [1] [2]; so, it isn''t representative of emissions from concrete batching operations. Cement and concrete are often misused as interchangeable terms. Cement is an ingredient of concrete while concrete is a mixture of cement, water, fine aggregate (sand)
