2013-3-22 Emissions from the facility are mainly from sizing the material and the internal combustion engines, which are used to operate the grinders and trommel screen. Each piece of equipment has its own dedicated engine, which has been sized based on the equipment. The applicant used engine model specific emissions data whenever available for particulate matter (PM), oxides of nitrogen (NOx), and carbon monoxide (CO). AP-42 factors were used when model specific emission data was not available for estimated emission

2021-6-25 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
2 天前 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.
2021-7-19 available emissions estimation methods: stack sampling, emission factors, continuous emissions monitoring systems, and material balance. Section 4 presents the preferred methods which differ depending on the process and pollutant for which an estimate is to be made. Section 5 presents the alternative methods. Quality assurance
2020-4-7 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

2018-6-5 Raw materials are crushed using dry mills (hammer, toothed, swinging-arm, and runner types) or wet mills (ball and pebble types). Then, in the case of dry grinding, a quantity of finely milled fireclay grog (precalcined clay) and water is added to give the clay workability. In this preparation stage the process is varied depending
