Such factors facilitate estimation of emissions from various sources of air pollution. In most cases, these factors are simply averages of the available data of acceptable quality and are generally assumed to be representative of long-term averages for all facilities in the source category (i.e., a population average).

overview of the available emission estimation techniques, and the methods used in applying these techniques. Schematic representations are used for identified processes in order to highlight the points where emissions may be produced. This section also describes the potential fate - to air, water, or land pathways - of these emissions and waste ...

Equation 1 EFi = ER/m = [(Vi * Ci) /10 3]/ m where: EFi = emissions factor of metal pollutant i associated with PMresp., mg/kg-abr. ER = emission rate, mg/min Vi = air flow rate, m3/min

AP-42, Compilation of Air Pollutant Emissions Factors, has been published since 1972 as the primary compilation of EPA's emissions factor information. It contains emissions factors and process information for more than 200 air pollution source categories. A source category is a specific industry sector or group of similar emitting sources.

The use of emission factors is the simplest method to estimate emissions from surface finishing process sources. An emission factor relates the quantity of a pollutant released to the atmosphere with a specific activity or in this case a specific process. Emission factors summarized for each process are expressed as a

The purpose of the original document, Air Toxics Emissions Estimation Methods Evaluation, was to establish sound methods for estimating air toxic emissions. These methods would be used to develop emission inventories to support rule development, the operating permit and registration programs, and other studies.

Air Emissions The use of metal working fluids in metal shaping and metal removal processes may result in fugitive emissions in the form of smoke, mist, or vapor. Other processes may create more hazardous air emissions. Possible sources of air emissions in metal fabrication processes are: • smoke emissions from metal removal processes

Emission test results may provide more accurate emission estimates and should be considered for use. It may be acceptable to use previous valid source specific test results, or testing that the process equipment's manufacturer performed during a similar operating scenario.

are typically combinations of metal forming (shaping the substrate metal by a number of mechanical processes), cutting, machining (primarily for metal castings rather than sheet metal), punching (making holes), welding, grinding, and buffing. Some of these processes are also used after electroplating. Some electroplated products will receive a ...

3.0 Emission Estimation Estimates of emissions of listed substances to air, water and land should be reported for each substance that triggers a threshold. The reporting list and detailed information on thresholds are contained in The NPI Guide at the front of this Handbook. In general, there are four types of emission estimation techniques (EETs)

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 as cleanup are often overlooked.
