Background
On March 8, 2024, the United States Environmental Protection Agency (EPA) published emission guidelines for existing crude oil and natural gas facilities and published updated New Source Performance Standards (NSPS) for new and modified crude oil and natural gas facilities. States are required to prepare and submit state plans to implement federal Clean Air Act Section 111(d) emission guidelines adopted by EPA.
The purpose of the proposed rulemaking and Section 111(d) State Plan is to implement the emission guidelines for existing oil and gas facilities in 40 CFR Part 60, Subpart OOOOc and ensure that the State of Texas maintains the authority to regulate these sources.
The rule will address applicability, emission standards, monitoring, recordkeeping, testing, and reporting requirements for designated oil and gas facilities. The rules would set emission standards and/or control requirements for emissions of greenhouse gases (primarily methane) from existing facilities in this industry.
Please check this webpage for updates on the rulemaking process and public involvement opportunities.
