Report: Flaws in EPA drilling pollution data

WASHINGTON (AP) — Limited data and unreliable estimates on air pollution from oil and natural gas production is hindering the Environmental Protection Agency's efforts to police the drilling boom, the agency's internal watchdog said in a report released Thursday.

Inspector General Arthur Elkins Jr. said the EPA has failed to directly measure emissions from some pieces of equipment and processes, and some estimates it does have are of "questionable quality."

"With limited data, human health risks are uncertain, states may design incorrect or ineffective emission control strategies, and EPA's decisions about regulating industry may be misinformed," Elkins said.

The EPA, under President Barack Obama, has stepped up regulation of natural gas drilling, which has been booming thanks to hydraulic fracturing, or fracking. About 25,000 wells a year are being fracked, a process in which water, chemicals and sand are injected at high pressure underground to release trapped natural gas.

Obama also wants to expand natural gas production, as long as it doesn't damage the environment.

Oil and gas production, from the well site to processing plants to storage tanks and transmission lines, releases toxic and cancer-causing air pollutants, smog-forming gases and methane, a potent greenhouse gas blamed for global warming.
