The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
Calculation of Emissions from Road Transport; Compilation of an emission inventory; Calculation for different vehicle categories (passenger cars, light duty vehicles, heavy duty vehicles, mopeds and motorcycles) Pollutants covered: major air pollutants (CO, NOx, VOC, PM, NH 3, SO 2, heavy metals) greenhouse gas emissions (CO 2, N 2 O, CH 4)
The fugitive air pollutant emission factors from relief valves, piping valves, open-ended piping lines or drains, piping flanges, sample connections, and seals on pump and compressor shafts are discussed and included in the report EPA-458/R-95-017, "Protocol for Equipment Leak Emission Estimates" which is included in the Chapter 5 section of AP ...
This category includes hazardous air pollutants, as listed in Section 112 of the U.S. Clean Air Act (1970) and Clean Air Act (1990). The list can be found on Wikipedia at National Emissions Standards for Hazardous Air Pollutants , and on EPA at [1] .
If a gaseous emission sample is analyzed and found to contain water vapor and a pollutant concentration of say 40 ppmv, then 40 ppmv should be designated as the "wet basis" pollutant concentration. The following equation can be used to correct the measured "wet basis" concentration to a " dry basis " concentration:
The VOC Solvents Emissions Directive was the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. It covers a wide range of solvent-using activities, e.g. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products.
