AP-42 factors were used when model specific emission data was not available for estimated emission rates of other pollutants,
emission factor ratings that provide some indication of robustness or appropriateness of the emission factors. In a way, this is a quality rating of an emission factor. As an example, emission factor ratings for AP-42 electroplating emission factors range from a "B" for one emission factor.

1. An "A" accompanying an emission factor means that this factor is the weighted average ash content of the fuel burned, expressed as a percent. See, for example, SCC 1-01-001-01 on page 14.A-2. If the weighted average ash content of the pulverized anthracite coal burned were five percent (5%), then the PM10 emission factor would
An uncontrolled hexavalent emission factor of 2 mg/Ah (0.03 gr/Ah) is considered to be representative of uncontrolled emissions from a decorative chromium electroplating operation. (A more conservative estimate was selected for this emission factor due to the limited data available).
Appendix A.2 Emission factors for particles from uncontrolled metallurgical processes (abstracted from US EPA, 1972; Bond and Straub, 1972; and US NTIS, 1979, 1980a, 1980b, 1981, and 1986). process EF (kg particles/Mg raw material) aluminum production aluminum hydroxide 100.00 bauxite grinding 3.00 crucible furnace 0.95 prebake cell 47.00
emission factor ratings that provide some indication of robustness or appropriateness of the emission factors. In a way, this is a quality rating of an emission factor. As an example, emission factor ratings for AP-42 electroplating emission factors range from a "B" for one emission factor.
An emission factor is a representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that pollutant. These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant ...

3.3.6 Equations F-7a and F-7b may be used in lieu of the F or F c factors specified in Section 3.3.5 of this appendix to calculate a site-specific dry-basis F factor (dscf/mmBtu) or a site-specific F c factor (scf CO 2 /mmBtu), on either a dry or wet basis. At a minimum, the site-specific F or F c factor must be based on 9 samples of the fuel. Fuel samples taken during each run of a RATA are ...
As you identify emission sources, remember to include all sources of air contaminants, such as non-production units like welding or grinding. Also, be sure to include the emission of air contaminants resulting from all aspects of the operation of a process. Ancillary activities such .

The District has not prepared default emission calculation procedures for machining, grinding and sanding equipment. Emissions are typically calculated based on a material balance on the amount of material being processed. To obtain assistance identifying a procedure or emission factors for calculating emissions, contact the District.
The 3C-SiC nanopowder obtained by dry grinding of the formed free nanoporous layer (see Section 11.2) was directly dispersed in a Krebs buffer solution.The formed suspension was centrifuged at 5,000g for 3 min in order to sediment out large crystallites at the bottom of the centrifuge vials and to collect the useful top part of the suspension containing only very small (<10 nm) and uniformly ...
