shoes for sale in uk shoes for sale in uk ´╗┐Criteria Pollutant control from Clean Air Act modest success



Environmental protection is perhaps the biggest government domestic success of my generation. We rarely stop to think of pollution. The Clean Air Act, first in 1970, again in 1977 and then permanently in 1990, has 5 Criteria Poll shoes for sale in uk utants, and now, according to the Supreme Court, 5 greenhouse gases. The original 5 Criteria Pollutants are carbon monoxide CO, sulfur dioxide SO2, nitrogen oxide NOx, volatile organic compounds VOC, about 120 compounds and lead Pb. The new greenhouse gases are carbon dioxide CO2, methane CH4, nitrous oxide N2O, hydrachlorofluorocarbons HFCs, perchlorofluo shoes for sale in uk rochlorine PFC and sulfur hexafluorine SHF. Primary focus is on CO2 and methane. All greenhouse gases GHG are called carbon dioxide equivalents CO2E.



The original 5 Criteria Ambient outdoor Air Pollutants are reasonably c shoes for sale in uk ontrolled since 1970, most notably lead and carbon monoxide. Lead was phased out of gasoline in 1980 and is now a rare, local stationary plant issue. Carbon monoxide is not as big of problem thanks to the transportation and vehicle controls from 1990. Volatile organic compounds and nitrogen oxides are also better controlled. Sulfur dioxide was solved by the original cap and trade program that came in far below industry and EPA estimates $1,000 to $1,500 per ton 2,000 pounds. Sulfur now trades for around $700 per ton.



The Northeast Regional Greenhouse Gas Initiative RGGI is a voluntary state carbon cap and trade program selling carbon for about $10 per ton to industry. The West and MidWest are starting similar programs. Carbon should remain around $15 per ton for several years. shoes for sale in uk
