Anything related to air quality, air pollution, or the atmosphere
"The Scripps Institution of Oceanography will present fresh evidence during a science conference in San Francisco Tuesday that pollution from central Asia affects the intensity of winter storms in California's Sierra Nevada, which provides a portion of the water consumed in San Diego County."
"U.S. EPA [Friday] released a reworked package of proposed rules to tackle toxic emissions from 201,000 of the largest boilers and incinerators nationwide, hoping to clear up complaints from manufacturing groups as the agency clamps down on the industrial boilers that are one of the largest U.S. sources of harmful air pollution."
"The Obama administration said Thursday that a series of new air pollution rules for power plants would not cause power shortages, although the expert panel designated by the government to ensure electricity reliability warns that compliance with these rules could strain generating capacity.
"BALTIMORE — An environmental group said Wednesday that infrared video shows air pollution streaming from natural gas sites that have been sprouting up across the Chesapeake Bay watershed."
The first-ever rule to limit toxic mercury in coal-fired powerplant emissions is about to take effect. It will require updating antique equipment -- and part of the utility is fighting that tooth and nail, complaining about how costs will hurt the economy. But where plants have installed the new scrubbing devices, many new jobs have been created.
The culprits often are one or more significant lead emitters such as smelters, iron or steel foundries, waste incinerators, utilities, or lead-acid battery manufacturers. Piston-engine planes using leaded aviation gasoline are another source.
On Nov. 9, 2011, EPA signed a consent decree that requires the agency to receive from and approve a State Implementation Plan for DC, VI, and 43 states that don't have a fully approved one. Each state can determine how it wants to reduce haze. In some cases, the plan will rely on actions already taken, such as reductions in emissions from power plants or vehicles.
"The top U.S. environmental regulator will propose early next year twice-delayed rules on greenhouse gas emissions from power plants, she told the energyNOW television show."
"Stronger national standards on fine particulate matter could prevent 35,700 premature deaths and save Americans $281 billion per year, according to a new report. Earth Justice, the American Lung Association, and Clean Air Task Force published the report in conjunction with a petition they filed yesterday against the Environmental Protection Agency for failing to meet its deadline to revisit the standard."
"After deciding it isn't worth cleaning up one of the nation's dirtiest power plants, the owners of an aging coal-burner along the southwestern shore of Lake Michigan are shutting it down sooner than expected."
