WASHINGTON (AP) — The Environmental Protection Agency's internal watchdog says limited data and unreliable estimates on air pollution from oil and natural gas production are hindering the agency's efforts to police the drilling boom.
In a report Thursday, the EPA inspector general said the data problems could obscure human health risks, generate misinformed regulations on the industry, and incorrect or ineffective ways to reduce pollution.
