Air Emission Factors for Metals Finishing Operations

AP-42 electroplating emission factors range from a "B" for one emission factor, chromium to an "E" for other metal electroplating factors. Caution must be exercised when applying any emission factor. There are variables that affect emissions that are not always considered. There are a number of factors that affect the emissions rate and ...

• Some of the emission factors have been revised, and some new factors have also been included. The tables containing the emission factors indicate which factors are new, and which have been revised from the IPCC 1996 Guidelines and GPG2000. • The default oxidation factor is assumed to be 1, unless better information is available.

Steps for Determining Emission Factors

cleaner-than-required emission level when remanufactured (even if Class 3), federal requirements mandate that all subsequent remanufactures be to this emission level or cleaner. Therefore, if this is the case, use the appropriate emission factor associated with the tier from Table B-18a to determine the project baseline emission factors.
