On April 24, 2020 the Texas Commission on Environmental Quality (TCEQ) announced it is providing an opportunity for public comment and hearing on the draft revisions to Title V Oil and Gas Air General Operating Permit (GOP) Numbers 511, 512, 513, and 514.
Title V (Major Source) air permits are required by the Environmental Protection Agency under the Clean Air Act of 1990 for a major source with actual or potential emissions at or above the major source threshold for any air pollutant.
A public hearing on the draft GOPs will be held in Austin on May 26, 2020, at 10:00 a.m. in Building E, Room 201S, located at 12100 Park 35 Circle, Austin. The draft GOP’s are subject to a 30-day comment period. Comments must be received by May 27th.
The draft GOPs contain revisions based on recent federal and state rule changes, which include updates to the requirements tables; the addition of new requirements tables; and updates to the terms.
The Air General Operating Permit applies to all 254 Texas counties, however each of the four GOP permit numbers applies only to its own specific set of counties. All of the GOP permit numbers list the following targeted SIC (standard industrial classification) codes:
- 1311 Crude Petroleum and Natural Gas
- 1321 Natural Gas Liquids
- 4922 Natural Gas Transmission
- 4923 Natural Gas Transmission and Distribution

About Major Source Air Emissions Threshold Levels
The major source threshold for any air pollutant is 100 tons/year (the default value). Lower thresholds may apply in non-attainment areas, (but only for the pollutants that are in non-attainment). Major source thresholds for “hazardous air pollutants” (HAPs) are 10 tons/year for a single HAP or 25 tons/year for any combination of HAPs. Title V permits are also required for any source with a major source permit under EPA’s New Source Review Program.
