July 6, 2011–While primary standards are designed to protect human health, secondary standards are established to protect the environment. In the case of NOx and SOx, some of the primary targets include reduced aquatic and terrestrial acidification, and reduced nitrogen deposition on land and water.
May 25, 2011–Information sessions and webinars on possible health and environmental effects of aerial-applied chemicals used to fight wildfires will be held in various locations around the country during the 45-day public comment period that ends June 27, 2011.
May 18, 2011–More access was urged for records on oil and gas leasing, government-issued permits and leases related to metal mining, grazing livestock on public lands, harvesting ocean fish, operating chemical plants, drilling for oil, logging, building roads or strip malls, coal mining, filling wetlands, and more.
March 2, 2011–EPA is conducting a study of fracking, no matter where it is used (e.g., gas shale, oil shale, coalbed methane, tight sands). Public comment is being allowed as the agency's Science Advisory Board meets March 7-8, 2011, to review the draft study plan. Initial study and research results are possible by the end of 2012, and a report may be published some time in 2014.
December 8, 2010–This invasive grass that already has a grip on about 2 million acres in the West makes the rangeland it invades virtually worthless for grazing, harms many animals that contact it or try to eat it, increases wildfire risk, and creates monocultures that have very low biodiversity and crowd out numerous native plant and animal species.
November 3, 2010–This new tool allows any user online to create custom study areas based on a wide range of variables: address, ZIP code, county, city, township, facility, watershed, or geographic coordinates. Other environmental data can then be mapped onto that study area.
