These "regulations set limits on sulfur oxide (SOx) and nitrogen oxide (NOx) emissions from ship exhausts and prohibit deliberate emissions of ozone-depleting substances." [ 1 ] The current convention is a combination of 1973 Convention and the 1978 Protocol.
The directive specified emission limits for sulphur dioxide, nitrogen oxides, and dust. [2] The directive was issued in October 2001. It replaced the earlier EEC directive on large combustion plants, 88/609/EEC, issued in November 1988. [3] Under the terms of the directive, combustion plant built after 1987 had to comply with specific emissions ...
An emission performance standard is a limit that sets thresholds above which a different type of vehicle emissions control technology might be needed. While emission performance standards have been used to dictate limits for conventional pollutants such as oxides of nitrogen and oxides of sulphur (NO x and SO x ), [ 3 ] this regulatory ...
Maximum sulfur content is specified for gas oil fuels (other than fuels used in vehicles) at 0.2% effective by July 2000 and 0.1% by January 2008. The details of the Protocol are identified in a series of Annexes that address specific pollutants and emission source sectors (e.g. Annex V: "Limit values for emissions of nitrogen oxides from ...
US counties that are designated "nonattainment" for the Clean Air Act's NAAQS, as of September 30, 2017. The U.S. National Ambient Air Quality Standards (NAAQS, pronounced / ˈ n æ k s / naks) are limits on atmospheric concentration of six pollutants that cause smog, acid rain, and other health hazards. [1]
The output from the model says that annual emissions of sulfur dioxide were reduced by 8 million tons (from 17.3 to 9.3), nitrogen oxides by 2.7 million tons (from 7.6 to 5), and mercury by 10 tons (from 52 to 42).
Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns.
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.
