Reducing Emissions of Methane and Other Pollution from Oil and Natural Gas Operations

Reducing Emissions of Methane and Other Pollution from Oil and Natural Gas Operations (40 CFR Part 60, Subparts OOOOb and OOOOc)

Methane, the primary component of natural gas, has been identified by the U.S. Environmental Protection Agency as the second-most prevalent greenhouse gas emitted in the United States from human activities.

With federal estimates that the natural gas and oil industries account for a quarter of U.S. methane emissions, reducing methane leaks from the oil and gas sector is one of the essential steps needed to reduce global greenhouse gas emissions and reduce the impacts of climate change.

In March 2024 EPA finalized a federal rule to reduce emissions of methane and other pollution from oil and natural gas operations and related actions.  The rule includes New Source Performance Standards (NSPS) to reduce methane and smog-forming volatile organic compounds (VOCs) from new, modified and reconstructed sources (OOOOb). It also included Emissions Guidelines (OOOOc), which set procedures for states to follow as they develop plans to limit methane from existing sources. The EPA expects the new rule to reduce methane emissions by 80%.

DEP is finalizing a State Plan that details the implementation and enforcement plan for the EPA’s New Source Performance Standards and Emissions Guidelines for greenhouse gas (GHG) emissions from oil and natural gas facilities.

What's New

The Bureau of Air Quality (BAQ) is conducting meaningful engagement efforts to hear from stakeholders their feedback on the State Plan.  BAQ presented details of the State Plan at regularly scheduled Advisory Committee meetings. To review the presentations, follow the links below:
