... for PM, and ACRP Report 6: Research Needs Associated with Particulate Emissions at Airports (U.S.
From page 6...
... The complex reactions that take place as a result of nucleation, condensation, accumulation, and reaction illustrate why measuring PM emissions can be so complex. Aircraft engine emission standards apply at the engine exit, yet PM of concern to regulators and the community is not fully formed at that point.
From page 7...
... In other cases, specific emission factors are compiled for each emission source. For example, regulated gaseous emission factors for aircraft engines are included in the International Civil Aviation Organization (ICAO)
From page 8...
... Aircraft engines have certification requirements for smoke emissions; ground access vehicles are subject to tailpipe emission standards; the composition of jet fuel, diesel fuel, and gasoline are regulated; many operational activities and equipment require operating permits; and federal airport actions (such as construction) are subject to the general conformity regulations in locations where the regional air quality does not meet health standards.
From page 9...
... Recently, ACRP published a study entitled ACRP Report 6: Research Needs Associated with Particulate Emissions at Airports and, now, this report. Such ACRP initiatives help bring needed focus to airport-specific PM emission concerns.
From page 10...
... With regard to GSE, EPA has taken steps to reduce PM emissions from nonroad vehicles. In response to national environmental regulations, refiners will begin producing lowsulfur diesel fuel for use in locomotives, ships, and nonroad equipment, including GSE.
