Rule Summary

Section 111 of the Clean Air Act (CAA) requires the EPA to list categories of stationary sources, if such sources cause or contribute significantly to air pollution, which may reasonably be anticipated to endanger public health or welfare. The EPA must then issue performance standards for such source categories.

This new source performance standard regulates both volatile organic compound (VOC) and greenhouse gases (GHG) emissions from specific sources within the oil and natural gas industry which include new, modified, and reconstructed compressors, pneumatic controllers, pneumatic pumps, well completions, fugitive emissions from well sites and compressor stations, and equipment leaks at natural gas processing plants.

Notification Requirement for Well Completions Begins October 15, 2012

Beginning October 15, 2012, gas well completion notification provisions under EPA's 2012 oil and gas standards take effect. Companies can meet this provision by complying with state advance notification requirements. If a state does not have an advance notification requirement, companies must inform EPA no later than two days before the well completion using hydraulic fracturing begins. Companies may submit this notification electronically or in writing. EPA finalized this approach after receiving feedback from industry, states and others during the 100-day public comment period. Companies have until 2015 to meet the green completion requirements in the final rule.

On August 16, 2012, EPA published the notification requirement in Oil and Natural Gas Sector: New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants Reviews; Final Rule (pdf) (112pp, 1.0 MB). Owners or operators that need to notify EPA may send a notification email to the appropriate region at the address listed below.
