The Environmental Compliance Information for Energy Extraction (ECIEE) Portal is intended to help you comply with environmental regulations that affect the exploration/development, extraction, production and processing of on-shore crude oil and natural gas. The site includes overviews of the regulations and links to more detailed information and other resources that can help this sector operate in an environmentally responsible manner.

This website was developed and is maintained by the National Center for Manufacturing Sciences. Funding for this project has been provided by EPA under the National Compliance Assistance Centers program.

State Review of Oil and Natural Gas Environmental Regulations (STRONGER) and the Environmental Council of the States convened an Oil and Natural Gas Stakeholder Roundtable during November 2019 in Albuquerque, New Mexico, bringing a diverse group of stakeholders together to discuss solutions to critical environmental challenges. The event summary is available on STRONGER’s website.

Pigging Alert – EPA and state investigations have identified Clean Air Act (CAA) non-compliance caused by unauthorized and/or excess emissions from depressurizing pig launchers and receivers in natural gas gathering operations.

Existing Owner Audit Program for oil and natural gas production facilities. In December 2019, EPA temporarily expanded its voluntary self-audit and disclosure program for upstream oil and natural gas facilities by giving existing owners the opportunity to find, correct, and self-disclose Clean Air Act violations.

The Ground Water Protection Council (GWPC) released a 'Produced Water Report' on June 24, 2019, that examines current regulations, practices, and research needed to expand the use of produced water, a byproduct of oil and gas production, as a resource.

EPA finalized a New Owner Clean Air Act Audit Program tailored for the oil and natural gas sector. The program encourages new owners to voluntarily find, correct and self-disclose Clean Air Act violations. The EPA believes that the program will accelerate the rate at which participating operators of newly-acquired facilities identify and correct emissions violations, resulting in significant pollutant reductions and increased environmental protection.

EPA’s Press Release and the Oil and Natural Gas New Owner Audit Program Policy Development Documents are available here.

Air Rules for the Oil and Natural Gas Industry - Compliance Assistance. EPA released a compliance guide to assist small businesses in understanding the requirements of the 2016 New Source Performance Standards for the Oil and Natural Gas Industry. The rule became effective August 2, 2016. Small Business Compliance Guide.

Compliance Alert: EPA Observes Emissions from Controlled Storage Vessels at Onshore Oil and Natural Gas Production Facilities. EPA published a Compliance Alert because EPA and state investigations have identified Clean Air Act compliance concerns regarding significant emissions from storage vessels, such as tanks or containers, at onshore oil and natural gas production facilities. The Alert discusses certain engineering and maintenance practices that may address compliance concerns and reduce emissions.
