WASHINGTON — The government has failed to inspect thousands of oil and gas wells it considers potentially high risks for water contamination and other environmental damage, congressional investigators say.
The report, obtained by The Associated Press before its public release, highlights substantial gaps in oversight by the agency that manages oil and gas development on federal and Indian lands.
Investigators said weak control by the Interior Department’s Bureau of Land Management resulted from policies based on outdated science and from incomplete monitoring data.
The findings from the Government Accountability Office come amid an energy boom in the country and the increasing use of hydraulic fracturing, or fracking. That process involves pumping huge volumes of water, sand and chemicals underground to split open rocks to allow oil and gas to flow. It has produced major economic benefits, but also raised fears that the chemicals could spread to water supplies.
The audit also said the BLM did not coordinate effectively with state regulators in New Mexico, North Dakota, Oklahoma and Utah.
The bureau has become a symbol of federal overreach to industry groups opposed to government regulations related to oil and gas drilling. Environmental groups say the Obama administration needs to do more to guard against environmental damage.
In the coming months, the administration is expected to issue rules on fracking and methane gas emissions.
The report said the agency “cannot accurately and efficiently identify whether federal and Indian resources are properly protected or that federal and Indian resources are at risk of being extracted without agency approval.”
In response to the report, Tommy Beaudreau, a principal deputy assistant interior secretary, wrote that he generally agreed with the recommendations for improved state coordination and updated regulations.
The report makes clear in many instances that the BLM’s failure to inspect high-priority oil and gas wells is due to limited money and staff. BLM officials said they were in the process of updating several of its policies later this year.
