Oil and Gas Facilities: Air Compliance Information

Air compliance tools for oil and gas facilities in Texas.

Air contaminants from upstream oil and gas operations are of concern to the TCEQ. Benzene, among others, is of particular interest because it is a known carcinogen and is often present in hydrocarbon emissions from these facilities.

Air Compliance Information

Title 30 Texas Administrative Code (TAC), Chapter 116, Subchapter B requires facilities that may emit air contaminants to obtain authorization prior to construction. The type of authorization required will depend on the type of facility and amount of contaminants emitted.

Air Permitting Options

Many oil and gas facilities will be subject to additional air regulations. Review the following for applicability.

  • Control of Air Pollution from:
    • Visible Emissions and Particulate Matter (30 TAC Chapter 111) – Requirements that may apply to sites with a combustion source. (30 TAC Chapter 111.111-111.113 )
    • Sulfur Compounds (30 TAC Chapter 112) - Requirements that may apply to sour sites.
    • Volatile Organic Compound (VOC) Sources (30 TAC Chapter 115) Requirements that may apply to facilities in the Beaumont–Port Arthur, Dallas–Fort Worth, and Houston Ozone Nonattainment Areas.
    • Nitrogen Compounds (NOx).(30 TAC Chapter 117)
    • Emissions Inventory
      • Owners and operators of facilities may also be subject to emissions inventory requirements located in 30 TAC §101.10. An emissions inventory must be submitted for facilities (sites) that have the potential to emit 100 tons per year (TPY) of any regulated pollutant, are a major source as defined in 30 TAC 116.2, or that operate in an ozone nonattainment area and emit more than 10 TPY of VOCs or 25 TPY of NOx, or emit or have the potential to emit 10 TPY of any single hazardous air pollutant (HAP) or 25 TPY of aggregate HAPs.
    • National Emission Standards for Hazardous Air Pollutants
      • Federal regulations that may apply to your facility are indexed at 40 CFR Part 63 - National Emission Standards for Hazardous Air Pollutants for Source Categories. The following subparts may apply:
        • Subpart H – Organic Hazardous Air Pollutants for Equipment Leaks
        • Subpart V – Equipment Leaks (Fugitive Emission Sources)
        • Subpart HH – Oil and Natural Gas Production Facilities
        • Subpart VV – Oil-Water Separators and Organic-Water Separators
        • Subpart HHH – Natural Gas Transmission and Storage Facilities
        • Subpart YYYY – Stationary Combustion Turbines
        • Subpart ZZZZ – Stationary Reciprocating Internal Combustion Engines
    • New Source Performance Standards
    • Air Operating Permits (Title V)
