Startup, Shutdowns, And Malfunctions
''Startups, shutdowns, and malfunctions'' (SSM) are periods of non-continuous operation in refineries, chemical plants or similar industrial facilities. During such temporary periods, these plants might emit larger amounts of pollution, and therefore the pollution abatement equipment may be unable to effectively control it. Recognizing this problem, beginning in 1994 the American Environmental Protection Agency (EPA) allowed such facilities to release large amounts of otherwise prohibited air pollution during SSM. However, in 2002 and again in 2003 the EPA made regulatory revisions which seemed to increase the allowable periods of such non-compliance periods, which motivated a coalition of environmental groups to challenge the changes, by suing the EPA. These groups argued that these changes effectively neutralized the United States Clean Air Act. The U.S. Court of Appeals for the District of Columbia issued a ruling on the lawsuitChemical & Engineering News, 5 January 2009, ...

Pollution
Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants Human impact on the environment, have a human source, such as manufacturing, Extractivism, extractive industries, poor waste management, transportation or Agricultural pollution, agriculture. Pollution is often classed as point source pollution, point source (coming from a highly concentrated specific site, such as a factory, Environmental effects of mining, mine, construction site), or nonpoint source pollution (coming from a widespread distributed sources, such as microplastics or agricultural runoff). Many sources of po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Clean Air Act
The Clean Air Act (CAA) is the United States' primary federal air quality law, intended to reduce and control air pollution nationwide. Initially enacted in 1963 and amended many times since, it is one of the United States' first and most influential modern environmental laws. As with many other major U.S. federal environmental statutes, the Clean Air Act is administered by the U.S. Environmental Protection Agency (EPA), in coordination with state, local, and tribal governments. EPA develops extensive administrative regulations to carry out the law's mandates. Associated regulatory programs, which are often technical and complex, implement these regulations. Among the most important, the National Ambient Air Quality Standards program sets standards for concentrations of certain pollutants in outdoor air, and the National Emissions Standards for Hazardous Air Pollutants program which sets standards for emissions of particular hazardous pollutants from specific sources.
