A proposed study of people in northern Pennsylvania could help resolve a national debate about whether the natural gas boom is making people sick.
The study would look at detailed health histories on hundreds of thousands of people who live near the Marcellus Shale, a rock formation in which energy companies have already drilled about 5,000 natural gas wells.
If the study goes forward, it would be the first large-scale, scientifically rigorous assessment of the health effects of gas production.
Natural gas pipeline company Energy Transfer Partners is buying Sunoco in a deal valued at about $5.3 billion.
The acquisition would give Energy Transfer the capability to transport crude and other liquid hydrocarbons that are being produced in greater quantities thanks to the boom in shale drilling. Sunoco's pipelines crisscross the country, connecting the Great Lakes and Northeast to America's refining center along the Gulf Coast.
The Environmental Protection Agency's new air pollution rules for the oil and gas industry may seem like odd timing, as President Obama has been trying to deflect Republican criticism that he overregulates energy industries. But the rules weren't the Obama administration's idea.
Several years ago, communities in Colorado, New Mexico and Wyoming complained about air pollution from natural gas booms in their local areas.
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.
