NRDC says GP-5/GP-5A and Pruitt’s proposed repeal of EPA’s oil and gas Control Techniques Guideline are major issues for Pennsylvania.

March 30, 2018

“In yet another step to dismantle critical protections for air and climate, EPA Administrator Scott Pruitt has proposed to withdraw the EPA’s guideline for states to reduce smog-forming air pollution from oil and gas production and processing activities,” according to a March 15, 2018 report from the Natural Resources Defense Council (NRDC).

“If this latest rollback goes final and withstands court review, Americans living in oil and gas regions will be forced to breathe more lung-damaging smog and cancer-causing pollution, while suffering more methane-driven climate warming,” says NRDC.

Under the Clean Air Act, states have to cut smog-forming pollution to meet the national health standard for ozone, through State Implementation Plans. Generally, states have significant discretion in how to do so. But when EPA issued the “control techniques guideline” (CTG) for ozone-forming pollution from the oil and gas industry—essentially a set of recommendations for improving air pollution controls for the sector—it triggered an obligation under the Clean Air Act for the states with smog problems and oil and gas operations to revise their state plans to reflect the guideline.

Pruitt’s proposed repeal now throws all that into uncertainty, heightening threats from ozone pollution to the health of families living near and downwind oil or gas development.  This outcome is good for no one.

State agencies will lose their strongest tool to assure that upwind states do their part to curb oil and gas pollution that travels across state lines, as well as the assurance of a level playing field among oil and gas states. Oil and gas production companies may now face different programs in different states (instead of seeing all programs built on the same guidelines). And most important, the public will have to wait even longer for air that is safe to breathe.

The Control Techniques Guideline targets emissions of volatile organic compounds (VOCs) from existing oil and gas facilities—pollution that forms ozone smog when it reacts in sunlight with nitrogen oxides. EPA issued the guideline in 2016, alongside a set of different federal standards to cut methane and VOC pollution from new installations nationwide. Like the methane standards, the CTG relies on readily available and cost-effective measures to cut air pollution from oil and gas equipment, through curbs on leaks, venting, and flaring. (Scott Pruitt is also trying to kill the methane standards, but so far without success, as we explain here.)

According to a report by the Clean Air Task Force (CATF), oil and gas air pollution contributes to unhealthy air quality in urban and rural areas throughout the country. Wyoming, for instance, now has ozone pollution rivaling Los Angeles’s.

Pennsylvania, the nation’s second-largest producer of natural gas, is near the top of the list of states most affected by oil and gas air pollution. The CATF report identifies the Commonwealth as one of the four states with the most asthma attacks attributable to industry pollution. The others are Texas, Oklahoma, and Colorado.

In most states the CTG applies only to oil and gas facilities located in or near the areas with unhealthy ozone smog levels. In Pennsylvania, by contrast, the CTG applies across the entire state, because Pennsylvania lies within the “Ozone Transport Region,” the northeastern U.S. region particularly afflicted by ozone smog.  For these reasons, withdrawing the CTG could affect Pennsylvania more than any other state.

Coincidentally, Pennsylvania’s Department of Environmental Protection (DEP) published its proposal to implement the oil and gas CTG the very day that Scott Pruitt announced his proposal to roll it back. At the same time, the Department is preparing to finalize pollution control measures covering new oil and gas production and transmission sources. Those long-awaited requirements, in the form of “general permits” known as GP-5 and GP-5A, are expected to significantly reduce emissions of methane, VOCs, and other pollutants from new sources.

But neither of these requirements for new sources will cover the hundreds of thousands of already operating oil and gas sources in the state, which the Environmental Defense Fund has found emit about 54,000 tons of VOCs per year—about nine times higher than what companies are reporting to the DEP—and about 520,000 tons of methane (five times more than companies’ self-reported data show).

So, Pennsylvania’s preparations to implement the controls recommended by the EPA CTG is a major step forward—and Scott Pruitt shouldn’t now be allowed to pull the rug out from under the state.

What this means to you
EPA Administrator Scott Pruitt has proposed to withdraw the EPA’s Control Techniques Guidelines for states to reduce smog-forming air pollution from existing oil and gas production and processing activities. Withdrawing the guideline could affect Pennsylvania more than any other state. Pennsylvania is also preparing to finalize pollution control measures covering new oil and gas production and transmission sources. Those long-awaited requirements, in the form of “general permits” are known as GP-5 and GP-5A.
