Mississippi Power's Kemper County energy facility near DeKalb, Miss., seen under construction last year. Carbon dioxide will be captured from this plant and used to stimulate production of oil from existing wells.
The Environmental Protection Agency's second stab at a proposal to set the first-ever limits on greenhouse gas emissions from new power plants would make it impossible for companies to build the kind of coal-fired plants that have been the country's biggest source of electricity for decades.
Under the proposal, released Friday, any new plant that runs on coal would be permitted to emit only about half as much carbon dioxide as an average coal plant puts into the air today.
More than 40 years ago, the EPA banned oil companies from releasing wastewater into the environment, but made an exception for the arid West. If livestock and wildlife can use the water, companies can release it. Cows like these grazing near a stream of waste on the Wind River Reservation in Wyoming are supposedly the reason the EPA lets oil companies release their waste into the environment.
The Environmental Protection Agency is proposing to let oil companies continue to dump polluted wastewater on the Wind River Reservation in Wyoming. This includes chemicals that companies add to the wells during hydraulic fracturing, an engineering practice that makes wells produce more oil.
