TCEQ Air Permit Compliance: Everything Operators Need to Know
Updated March 2026 · 10 min read
Air quality compliance is one of the most complex and heavily enforced areas of environmental regulation for Texas oil and gas operators. TCEQ administers a layered system of air authorizations, each with its own set of operating conditions, monitoring requirements, and reporting obligations.
This guide covers the air permit framework, ongoing compliance obligations, and common pitfalls that lead to violations.
Types of Air Authorizations
TCEQ issues several types of air authorizations for oil and gas facilities, ranging from simple registrations to complex individual permits:
Permit by Rule (PBR)
PBRs are pre-approved authorizations for facilities that meet specific criteria. Many small oil and gas production sites operate under PBR, particularly 30 TAC Section 106.352 (Oil and Gas Facilities) and 106.353 (Compressor Stations). PBRs have emission limits and operating conditions that must be followed, but they do not require individual permit applications. Operators must maintain records demonstrating they qualify for and comply with the PBR.
Standard Permits
Standard permits cover specific facility types that have common configurations and predictable emissions. Oil and gas standard permits cover facilities that exceed PBR thresholds but fit within standardized categories. Registration under a standard permit requires a one-time application to TCEQ.
New Source Review (NSR) Permits
NSR permits are individual, site-specific permits required for facilities with emissions above PBR and standard permit thresholds, or that do not fit standard categories. NSR permits have detailed conditions including specific emission limits for each source, monitoring and testing requirements, recordkeeping obligations, and reporting schedules. The NSR permitting process involves a detailed application, TCEQ technical review, public notice, and can take 6-18 months.
Federal Operating Permits (Title V)
Title V permits are required for "major sources" — facilities with potential emissions exceeding 100 tons per year of any criteria pollutant (or lower thresholds for HAPs). Title V permits consolidate all applicable air requirements into a single document and carry the most extensive compliance obligations, including annual compliance certifications to both TCEQ and EPA.
Ongoing Compliance Obligations
Monitoring and Testing
Depending on your permit type, you may need to conduct continuous emissions monitoring (CEMS) for specific pollutants, periodic stack testing to verify emission rates, parametric monitoring (temperature, pressure, flow rates) as surrogates for emissions, and leak detection and repair (LDAR) surveys for fugitive emissions. Each monitoring requirement has specific frequencies, methods, and documentation standards that must be followed exactly.
Recordkeeping
Air permit recordkeeping requirements are extensive. Operators must maintain records of all emissions calculations, monitoring data, equipment operating hours, maintenance activities, and any deviations from permit conditions. Records must be kept for at least 5 years and be available for TCEQ inspection at any time.
Deviation Reporting
Any time your facility operates outside of permit conditions — whether due to equipment malfunction, upset conditions, or operational error — you must report the deviation. Semi-annual deviation reports are required for NSR and Title V permits. Material deviations must be reported within specific timeframes outlined in your permit.
Annual Emissions Inventory
Facilities that exceed emissions reporting thresholds must submit an Annual Emissions Inventory to TCEQ by March 1. The inventory must accurately account for all criteria pollutants and hazardous air pollutants emitted during the previous calendar year, including both normal operations and upset events.
Common Air Permit Violations
The most common air permit violations TCEQ cites against oil and gas operators include:
- Operating without the correct authorization or exceeding PBR emission limits
- Failure to conduct required monitoring or testing
- Inadequate or missing recordkeeping
- Late or inaccurate emissions inventory filings
- Unreported emissions events
- Failure to submit deviation reports
- Operating equipment not represented in the permit
Permit Amendments and Modifications
Any change to your facility that increases emissions, adds new equipment, or alters the way you operate must be evaluated for permit implications. Depending on the change, you may need a permit amendment, a new PBR registration, or even a new NSR permit. Operating modified equipment without the proper authorization is one of the most common — and most costly — violations.
