Mercury emissions

Mercury emissions:

In March 2005, nine states (California, New York, New Jersey, New Hampshire, Massachusetts, Maine, Connecticut, New Mexico and Vermont) sued the EPA. The EPA's inspector general had determined that the EPA's regulation of mercury emissions did not follow the Clean Air Act, and that the regulations were influenced by top political appointees. The EPA had suppressed a study it commissioned by Harvard University which contradicted its position on mercury controls. The suit alleges that the EPA's rule allowing exemption from "maximum available control technology" was illegal, and additionally charged that the EPA's system of pollution credit trading allows power plants to forego reducing mercury emissions. Several states also began to enact their own mercury emission regulations. Illinois's proposed rule would have reduced mercury emissions from power plants by an average of 90% by 2009M
