Oil and Natural Gas Production Facilities: National Emission Standards for Hazardous Air Pollutants (NESHAP)

Rule Summary

The Environmental Protection Agency (EPA) issued final rules to reduce emissions of hazardous air pollutants (HAPs) from oil and natural gas production facilities as well as natural gas transmission and storage facilities. These rules implement section 112 of the Clean Air Act (CAA).

Emissions from various processes and operations at oil and natural gas facilities and natural gas transmission and storage facilities typically contain 5 different HAPs: benzene, toluene, ethyl benzene, and mixed xylenes, and n-hexane. HAPs, also known as air toxics, are pollutants which are known or suspected to cause cancer or other serious health effects such as birth defects or reproductive effects.

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.
