On Friday, the Environmental Protection Agency's internal watchdog, the inspector general released a scathing report on the agency's failure to control leaks from the nation's natural gas distribution system.
The report, titled “Improvements Needed in EPA Efforts to Address Methane Emissions From Natural Gas Distribution Pipelines,” describes a string of failures by the EPA to control leaks of one of the most potent greenhouse gases, methane, from the rapidly expanding natural gas pipeline industry.
“The EPA has placed little focus and attention on reducing methane emissions from pipelines in the natural gas distribution sector,” the report begins. “The EPA has a voluntary program to address methane leaks — Natural Gas STAR — but its efforts through this program have resulted in limited reductions of methane emissions from distribution pipelines.”
To date, the industry has faced little binding regulation on leaks, in part because the EPA assumes that pipeline companies will not allow the product they are attempting to bring to market to simply disappear. But the reality is that when gas is cheap and repairs are expensive, pipeline companies often put off repairs unless there's a threat of an explosion.
Under many state policies, pipeline companies would have to pay upfront costs for pipeline repairs — or they simply choose to pass the cost of lost gas from unrepaired leaks on to consumers, an issue that the audit faults the EPA for failing to take into account.
Nationwide, the Inspector General report concluded $192 million worth of natural gas was lost from pipelines in 2011 alone.
