The Environmental Protection Agency announced new rules Wednesday to control the problem of air pollution coming from wells being drilled by the booming oil and natural gas drilling industry.
Currently, waste products from the drilling operations, which include a mix of chemicals, sand and water, can be pumped into open enclosures or pits, where toxic substances can make their way into the air. The new rules will require this fluid to be captured by 2015, and flared — or burned off — in the meantime.
Oil field workers drill into the Gypsum Hills near Medicine Lodge, Kan. Hydraulic fracturing, or "fracking," to coax out oil and gas has led to a natural gas boom that the U.S. market is having trouble absorbing.
There's a boom in natural gas production in the United States, a boom so big the market is having trouble absorbing it all.
The unusually warm weather this winter is one reason for the excess, since it reduced the need for people to burn gas to heat their homes. A bigger reason, however, is the huge increase in gas production made possible by new methods of coaxing gas out of shale rock formations.
