Emissions standards for

National Emission Standards for Hazardous Air Pollutants (NESITAP)... 

Once a substance is designated by EPA as a ha2ardous air pollutant (HAP), EPA has to promulgate a NESHAP (National Emission Standard for Ha2ardous Air Pollutants), designed to protect pubHc health with an ample margin of safety. 

U.S. Environmental Protection Ageny Report No. EPA-450/2-75-009, Environmental Protection Agency, Research Triangle Park, N.C., Oct. 1975. EPA Regulations, 40 CFR 61, Subpart F—National Emission Standard for Viayl Chloride, Aug. 27, 1993.

Finally, Sec. 112 of the Clean Air Act required that EPA pronml-gate National Emission Standards for Hazardous Air Pollutants (NESHAPs). Between 1970 and 1989, standards were promulgated for asbestos, beiylhum, mercuiy, vinyl chloride, benzene, arsenic, radionuclides, and coke-oven emissions. 

Explain why stringent emission standards for particulate matter based on mass/heat input will do little to improve visual air quality. 

Title I allows the EPA to define the boundaries of "nonattainment" areas for ozone, CO, and PMjg. Emission standards for these areas will be based on a new set of "nonattainment categories." EPA has established a classification system for ozone design values (goals) and attainment deadlines. Table 24-2 lists these parameters. 

Before the U.S. Clean Air Act Amendments of 1990 (3), hazardous air pollutants were regulated through federal promulgation of the National Emission Standards for Hazardous Air Pollutants (NESHAPS). The EPA listed only eight hazardous air pollutants under NESHAPS. 

Promulgate technology-based emission standards for lisfed pollutants and sources. 

F. Emission Standards for Existing Installations in the United States... 

The states and cities of the United States sometimes have emission standards for existing installations, which are usually less restrictive than those... 

The most recent compilation of emission standards for processes and substances emitted from processes in the industrialized countries of the world was the companion Volume II of the source of Table 22-10 (see Jarrault in Suggested Reading). 

A key parameter in the design of the fuel vapor control system is the volume of activated carbon required to meet the emission standards for the various regulatory tests. In the case of the three-day diurnal test sequence, the emission limits are 0.05 grams of HC per mile during the run loss portion of the test (maximum emission -0.85 grams), and a maximum release of 2.0 grams for the sum of the hot soak period and any one of the three 24-hour periods making up the diurnal test sequence.

In April of 1998, the EPA published a final rule for emission of oxides of nitrogen (NOx), hydrocarbons (EIC), carbon monoxide (CO), particulate matter (PM), and smoke opacity for newly manufactured and rcmanufacturcd locomotives. The rulemaking took effect in 2000 and is estimated by the EPA to cost the railroads 80 million per year—about 163 per ton of NOx reduced, according to EPA figures. The emissions standards for the several pollutants will be implemented in three tiers—for locomotives... 

The latest revision of Emission Standards for New Vehicles was issued in September 1988. A summary of past and present emission standards is given in Table III. 

The Emission Standard for New Diesel Vehicles, issued in December 1988, established a maximum of 50 Hartridge Opacity Units. The Ecological Technical Standard of June, 1988, enforced the maximum allowable emissions for circulating cars (Table IV). The Diesel Regulation... 

More stringent emission standards for automotive transportation, requiring for example, low-sulfur fuels (eventually lower than 10 ppm).
