Consistent with the Montreal Protocol, the Clean Air Act requires that EPA develop and implement regulations for the responsible management of ozone-depleting substances just a girl who loves christmas and horses christmas ugly sweater in the United States to help restore the ozone layer. The law uses multiple tools including the phase-out of certain chemicals, bans on nonessential products containing or made with such chemicals, and prohibition of the release of ozone-depleting refrigerants during the service, maintenance, and disposal of air conditioners and other refrigeration equipment. The benefits of MATS are widely distributed and are especially important to minority and low income populations who are disproportionately impacted by asthma and other debilitating health conditions. Power plants remain the largest man-made source of mercury emissions
in the United States, emitting more than half of all emissions of certain air toxics. Mercury emissions fell by about 80 percent between 1990 and 2014.6 EPA regulations for several large sources of mercury such as municipal waste combustion and medical waste incineration played a significant role. Onroad and nonroad diesel particulate matter emissions decreased by about 27 percent from 1990 to 2005 and are projected to be reduced an additional 90 percent from 2005 to 2030. Toxic emissions from onroad and nonroad vehicles and engines also are dropping due to requirements for cleaner fuels and engines.4These emissions are projected to be reduced by 80 percent by 2030 from 1990 levels. On September 7, 2016, the EPA revised the CSAPR by finalizing an update for the 2008 ozone NAAQS, known as the CSAPR Update. CSAPR Update will further reduce summertime NOX emissions from power plants in the eastern U.S. and help downwind states to meet the new ozone standards.
