The AP 42 Compilation of Air Pollutant Emission Factors, was first published by the U.S. Public Health Service in 1968. In 1972, it was revised and issued as the second edition by the U.S. Environmental Protection Agency (EPA). In 1985, the subsequent fourth edition was split into two volumes. Volume I includes stationary point and area source emission factors, and …
These emission factors do not include emissions from use of the fuel in the building, which is reported in Section 5.3. ... Unless otherwise noted, these emission factors are based on data from GREET 1.6 (ANL 2005), which uses EPA AP-42 (EPA 2005B) and other sources. The numbers include the emissions from combustion on site; the precombustion ...
The Universal Render Pipeline (URP) aims to optimize real-time performance on traditionally performance-constrained platforms, such as mobile devices or low-end consoles and PCs. It does this by making some tradeoffs in the lighting and shading sections of the pipeline. If you wish to target a wide range of mobile devices, virtual reality, or your project has a limited need for real …

The AP-42 Background Documents provide background information on how the AP-42 emissions factors were obtained. These documents include a literature review, emissions factor methodologies and reference materials. Most background documents are available on this site under the corresponding AP-42 chapter page.

To account for the variability, the EPA ranks the emission factors found within the AP-42 database. This ranking serves as a guide to determine the suitability and the overall robustness of an emission factor to serve in a specific situation. Ranking an emission factor is a two-step process that is largely dependent on professional judgment.
These were combined with the 7 data points from the existing AP-42 Document, making a total of 172 data points. The existing emission factor was 1.6 Ib/ton bagasse with an overall rating or "B". By combining the new data, the emission factor is 1.4 Ib/ton bagasse with an overall rating of …
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.

Section 1.5 in AP-42, the subject of this Emission Factor Documentation (EFD) report, pertains to liquefied petroleum gas (LPG) combustion. Section 1.5, Liquefied Petroleum Gas Combustion, was previously updated in 1982. The purpose of this current revision is to review and update, if possible, the prior emission factor development for criteria ...
Emission factor is developed primarily from A or B rated test data from a moderate number of facilities. Although no specific bias is evident, is not clear if the facilities tested represent a random sample of the industry. As with the A rating, the source category population is sufficiently specific to minimize variability. C = Average.

The EPA also routinely updates AP-42 in response to the needs of Federal, state, and local air pollution control programs and industry. An emission factor relates the quantity (weight) of pollutants emitted to a unit of source activity. Emission factors reported in AP-42 are used to: 1. Estimate areawide emissions. 2. Estimate emissions for a ...
