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.
Section 202(a)(1) of the Clean Air Act requires the Administrator of the EPA to establish standards "applicable to the emission of any air pollutant from…new motor vehicles or new motor vehicle engines, which in [her] judgment cause, or contribute to, air pollution which may reasonably be anticipated to endanger public health or welfare" (emphasis added). [3]
Standards for performing a Phase I site assessment have been promulgated by the US EPA [1] and are based in part on ASTM in Standard E1527-13. [ 2 ] If a site is considered contaminated, a Phase II environmental site assessment may be conducted, ASTM test E1903, a more detailed investigation involving chemical analysis for hazardous substances ...
The United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.
Energy Star (trademarked ENERGY STAR) is an energy-efficiency program administered by the U.S. Environmental Protection Agency (EPA) in partnership with the U.S. Department of Energy (DOE). [2] [3] [4] The EPA establishes energy efficiency specifications, and those that meet these specifications are eligible to display the ENERGY STAR logo. [5]
The start of the energy services business can be attributed to the energy crisis of the late 1970s, as entrepreneurs developed ways to combat the rise in energy costs. One of the earliest examples was a company in Texas, Time Energy, which introduced a device to automate the switching of lights and other equipment to regulate energy use.
EPA efforts to promote prevention practices include waste permitting procedures, revisions to regulations, technical assistance to industry and government agencies, and enforcement. The agency also makes efforts to link pollution prevention to public information about chemicals, such as in the TRI program.
EPA tests for fuel economy do not include electrical load tests beyond climate control, which may account for some of the discrepancy between EPA and real world fuel-efficiency. A 200 W electrical load can produce a 0.94 mpg (0.4 km/L) reduction in efficiency on the FTP 75 cycle test.
