Four in 10 new oil and gas wells near national forests and fragile watersheds or otherwise identified as higher pollution risks escape federal inspection, unchecked by an agency struggling to keep pace with America's drilling boom, according to an Associated Press review that shows wide state-by-state disparities in safety checks.
Roughly half or more of wells on federal and Indian lands weren't checked in Colorado, Utah and Wyoming, despite potential harm that has led to efforts in some communities to ban new drilling.
In New Castle, a tiny Colorado River valley community, homeowners expressed chagrin at the large number of uninspected wells, many on federal land, that dot the steep hillsides and rocky landscape. Like elsewhere in the West, water is a precious commodity in this Colorado town, and some residents worry about the potential health hazards of any leaks from wells and drilling.
"Nobody wants to live by an oil rig. We surely didn't want to," said Joann Jaramillo, 54.
About 250 yards up the hill from Jaramillo's home, on land that was a dormant gravel pit when she bought the house eight years ago, is an active drilling operation that operates every day from 7 a.m. until sometimes 10:30 p.m. Jaramillo said the drilling began about three years ago.
Even if the wells were inspected, she questioned whether that would ensure their safety. She said many view the oil and gas industry as self-policing and nontransparent.
"Who are they going to report to?" she asked.
Government data obtained by the AP point to the Bureau of Land Management as so overwhelmed by a boom in hydraulic fracturing, or fracking, that it has been unable to keep up with inspections of some of the highest priority wells.
"No one would have predicted the incredible boom of drilling on federal lands, and the number of wells we've been asked to process," said the BLM's deputy director, Linda Lance.
Since fracking reached a height in 2009, about 90 percent of new wells on federal land are drilled by the process, which involves pumping huge volumes of water, sand and chemicals underground to break up gas-rich shale rock.
"The current rate of inspections is simply not acceptable to us," she said.
The agency oversees 100,000 oil and gas wells on public lands, 3,486 of which received the high priority designation.
According to BLM records for fiscal years 2009 to 2012, 1,400 of those high priority wells, spread across 13 states, were not federally inspected. Wyoming had the most, 632, or 45 percent. South Dakota had 1 out of 2 wells uninspected, and Pennsylvania had 1 out of 6.
All the higher risk wells were inspected in six states — Alabama, Michigan, Mississippi, New York, Ohio and Texas.
Many more wells are located on private lands, where state officials take the lead in ensuring they comply with environmental laws, with mixed results.
Nationwide, there were nearly 500,000 producing gas wells in 2012, according to Energy Information Administration data. More than 1,800 new wells were being drilled in March alone.
Dennis Willis, a former BLM field officer in Price, Utah, says he routinely provided input on oil leasing and drilling decisions on federal land before his retirement in 2009. He described a situation of chronic underfunding dating to at least the early 2000s, when BLM management made clear that issuing new permits would be a priority over other tasks, according to a 2002 memorandum from supervisors in Utah to field officers. At the time, fracking was becoming more widely used.
"There certainly wasn't a shortage of spills, leaks, pipeline failures and other problems," said Willis, who now does consulting work for conservation and other groups.
"It's a disaster waiting to happen," he said.
In interviews, BLM officials acknowledged persistent problems in keeping up with inspections, but said they were not aware of any major safety issues to date arising from the uninspected wells.
Lance said BLM field managers are making judgment calls to minimize the risk of potential harm to surrounding communities. The agency also is reviewing whether it needs to slow down the pace of permits to ensure public safety.
Officials noted that money provided by Congress for oil and gas operations has declined since 2007. During that period, the number of wells drilled on federal and Indian lands has increased by roughly one-third.
"We're trying to do the best we can with limited resources," Lance said.
If approved by Congress, the BLM's 2015 budget request of $150 million for oil and gas operations would allow the agency to conduct the bulk of its required inspections over three years, in part by collecting fees from oil and gas companies. Unlike past years, $48 million will be earmarked for inspections. The BLM made similar budget requests the last several years with little success.
The BLM has sought to add inspectors, but that has proved challenging in places such as Utah, where most wells are drilled on federal land. While a petroleum engineer could get a starting salary of $90,000 in the private sector, the BLM typically pays $35,000. This year's appropriations bill would allow the BLM to increase inspector salaries to around $44,000.
The public concern is evident in Colorado, where increased drilling into suburban and rural areas has led community groups to push nearly a dozen oil and gas local control initiatives for the November ballot.
Jaramillo said residents in the canyon have mixed feelings about fracking.
"The people that really like it are the people who are getting money out of it," she said. "The people who don't are really worried about — Is it going to ruin the water? Is it going to ruin the land? Is it going to ruin the air?"
