- Emission factors from the diesel engine powering the tub grinder were taken from AP-42 (10/96), Section 3.4. PM emissions from bark grinding were shown as 0.16 lb/ton, as derived from stack testing on an identical unit operated in Arkansas. All combustion PM is assumed to be PM 2.5, and 10% of PM from wood grinding was assumed to be PM 2.5.

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…
Grinder Emissions No general accepted emission factors have bee established for vegetable by products grinding. The emission factor for hammermill grain grinding served by a baghouse from AP-42, Table 9.9.1-2 (3/03) for animal feed mills is expected to be conservative for this type of operation and will be used to estimate emissions.
The applicant used emission factors listed in documents published by the Bay Area Air Quality Management District of San Francisco and Sacramento Metropolitan Air Quality Management District to estimated PM emissions from grinder and sizing operations. The following table illustrates these emissions from the specific equipment.

A "grid emission factor" refers to a CO2 emission factor (tCO2/MWh) which will be associated with each unit of electricity provided by an electricity system. It is a parameter to determine the baseline emissions for CDM projects in the renewable energy sector (hydro, wind, solar PV, and geothermal power, etc.) and waste heat/gas recovery sector.
Emission factors are often used to estimate emissions from such industrial operations. Since the development of the emission factors for uncontrolled abrasive blasting operations, prepared for US EPA in 1995, several attempts were made to derive emission factors for particulates. This paper will provide
Emission Factor Search WebFIRE contains the EPA's emissions factors for criteria and hazardous air pollutants (HAP) for industrial and non-industrial processes. To retrieve emissions factors, select one or more search terms from the dropdown menus below then click on the "Submit Search" button at the bottom of the page.
Because of the wide variation in grains and grinders used, an average emission factor would be difficult to deter- mine. A small amount of data presented in Reference 2 (p. 163) in- dicated that controlled emissions may range from 0.02 to 0.2 Ib/ton. Considering these facts, and lack of other data, an average controlled emission factor of 0.1 ...

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. Emission factors usually are expressed as the weight of pollutant divided by the unit weight, volume, distance,

What are emission factors? Emission factors are greenhouse gas (GHG) emissions per unit of activity data. GHGs should always be reported in Carbon Dioxide Equivalent (CO 2 e), a common unit that normalizes all GHGs in terms of their the global warming potential (GWP) or global temperature change potential (GTP), depending on which set of greenhouse gas conversion factors, …
The District has not prepared default emission calculation procedures for wood and paper shredders/grinders. To obtain assistance identifying a procedure or emission factors for calculating emissions, contact the District.

emissions limit is for each state permit. The Indiana and Washington state permits do not regulate combustion emissions. Most state permits (Arizona, Florida, Indiana, Washington, and Wisconsin) require control of particulate emissions, but the Alaska permit does not. In Alaska, the water sprays typically used to control particulate may

Current emission factors: Because of the rigorous process PG&E follows to calculate and have its emission factors independently verified by a third party, the most recent year's GHG emission factor is not available until late in the following year. For example, the 2010 emission factor will not complete third-party verification until
