Stage I Vapor Recovery

An overview of the Stage I vapor recovery rules for owners and operators of gas dispensing facilities in Texas.

Stage I Vapor Recovery Rules - Change Now Effective

As of Oct. 31, 2014, owners and operators of gasoline dispensing facilities must comply with state regulations for their Stage I vapor recovery system. Depending on their monthly throughput and location, facilities are subject to Stage I record-keeping, testing, and inspection requirements. For a complete list of requirements for all affected counties, read the Stage I rules in 30 TAC Chapter 115, Subchapter C, Division 2 Exit the TCEQ.

What is Stage I vapor recovery?

Stage I vapor recovery is a control strategy to capture gasoline vapors that are released when gasoline is delivered to a storage tank. The vapors are returned to the tank truck as the storage tank is being filled with fuel, rather than released to the ambient air.

Is my facility subject to Stage I vapor recovery rules?

Applicability of the Stage I vapor recovery rules is determined by the county in which the gasoline dispensing facility is located and the gallons of gasoline that are dispensed from the facility in a month (monthly throughput).

If your facility is located in an affected county and dispenses greater than the monthly throughput listed for that county, your facility is subject to the Stage I rules. If your facility is located in an affected county and dispenses less than the monthly throughput listed for that county, your facility is exempt from the requirements of the Stage I rule with a few exceptions. Monthly throughput exemptions can be found in 30 TAC 115.227 Exit the TCEQ.

*If your gasoline dispensing facility is located in the Beaumont-Port Arthur, Dallas-Fort Worth, El Paso, and Houston-Galveston-Brazoria areas, your facility may be exempt from the Stage I rules if the facility has dispensed no more than 10,000 gallons of gasoline in any calendar month after January 1, 1991, and construction began prior to November 15, 1992.

**If your gasoline dispensing facility is located in a covered attainment county (30 TAC 115.10(10) Exit the TCEQ) and the capacity of the stationary gasoline storage containers is less than or equal to 1,000 gallons, your facility is exempt from the requirements of the Stage I rule with a few exceptions.

My facility is subject to the rule. What am I required to do?

If your facility is subject to the rule, you must comply with the following requirements:

  • Control displaced vapor emissions by either vapor control system or vapor balance system (30 TAC 115.221) Exit the TCEQ.
    • Operate a vapor balance system according to the conditions found in 30 TAC 115.222 Exit the TCEQ.
  • Inspect for liquid leaks, visible vapors or significant odors during gasoline fuel deliveries. Immediately discontinue any delivery if these items are observed, and do not resume until the observed issue is repaired (30 TAC 115.224(1)) Exit the TCEQ.
  • Ensure that the gasoline tank-truck has been inspected for leaks within one year (30 TAC 115.224(2)) Exit the TCEQ.
  • Conduct annual testing procedures according to 30 TAC 115.225 Exit the TCEQ. These two tests are:
    • California Air Resources Board Vapor Recovery Test Procedure TP 201.1EAdobe Acrobat PDF Document  - Leak Rate and Cracking Pressure of Pressure/Vacuum Vent Valves
    • California Air Resources Board Vapor Recovery Test Procedure TP-201.3: Adobe Acrobat PDF Document - Determination of 2-Inch WC Static Pressure Performance of Vapor Recovery Systems of Dispensing Facilities
  • Keep records of dates on which gasoline was delivered to your facility and the identification number and date of the last leak testing of each tank-truck tank from which gasoline was transferred to the facility (30 TAC 115.226(1)) Exit the TCEQ.
  • Maintain the following records for two years:

My facility is exempt from the rule. What am I required to do?

If your facility is located in an affected county and is exempt from the rule, based on monthly throughput, you must still comply with the following requirements:

  • Ensure there are no avoidable gasoline leaks in the liquid transfer or vapor balance systems (30 TAC 115.222(3)) Exit the TCEQ.
  • Ensure that the tank-truck is kept vapor-tight after unloading (30 TAC 115.222(6)) Exit the TCEQ.
  • Inspect for liquid leaks, visible vapors or significant odors during gasoline fuel deliveries. Immediately discontinue any delivery if these items are observed, and do not resume until the issue is repaired (30 TAC 115.224(1)) Exit the TCEQ.
  • Maintain monthly inventory records to show gasoline throughput (30 TAC 115.226(2)(B)) Exit the TCEQ. This requirement does not apply to facilities located in a covered attainment area with a stationary gasoline storage capacity of less than or equal to 1,000 gallons.

Are there other air regulations that apply to my facility?

Gasoline dispensing facilities located at area sources of Hazardous Air Pollutants are subject to state and federal regulations found in 40 CFR Part 63, Subpart CCCCCC (6C) Exit the TCEQ and adopted by reference in 30 TAC Chapter 113 Exit the TCEQ. Requirements include submitting an Initial Notification Report to the TCEQ. For more information, including an example notification report , visit the Area-Source Air Emissions Standards for Gasoline Dispensing Facilities Web page.
