TX HB3263

Establishes a methane emissions monitoring program within the Texas Commission on Environmental Quality (TCEQ) to adopt standards for methane and associated gas emissions in accordance with federal Clean Air Act requirements under Sections 111 and 112

Requires TCEQ to deploy continuous emissions monitoring devices in areas with substantial methane-emitting infrastructure, including oil and gas facilities, wastewater treatment plants, and pulp and paper facilities, to detect leaks, measure background levels, and provide real-time data

Mandates that facility operators identified as violating emission standards must repair or shut off the emission source within 30 days and cannot resume operations until authorized by the commission

Authorizes TCEQ to contract with third parties, including universities and nonprofit organizations, to operate monitoring sensors under the program

Allocates up to $2 million from the Texas Emissions Reduction Plan fund for the methane emissions program, adding it as an eligible use of plan funds alongside existing programs like diesel emissions reduction and clean school bus initiatives
