Current through Register Vol. 50, No. 6, June 20, 2024

Section III-2137 - Gasoline Terminal Vapor-Tight Control Procedure

A. Gasoline Tank Trucks

1. Testing Procedure. Gasoline tank trucks and their vapor collection systems shall not sustain a pressure change of more than 3 inches of water (0.75 kPa) in five minutes when pressurized to 18 inches of water (4.5 Kpa) or evacuated to 6 inches of water (1.5 Kpa) using Test Method 27 ( 40 CFR Part 60, Appendix A, as incorporated by reference at LAC 33:III.3003) for determination of vapor tightness of gasoline delivery tanks using pressure-vacuum test.

2. Inspection Sticker Required. All tank trucks must have a sticker displayed on each tank indicating the identification number of the tank and the date each tank last passed the pressure and vacuum test described in Paragraph A.1 of this Section. Each tank must be certified annually and the sticker must be displayed near the Department of Transportation certification plate. Any repairs necessary to pass the specified requirements must be made within 15 days of failure.

B. Vapor Collection System

1. Requirements for Potential Leak Source. Loading and unloading operations at gasoline terminals shall not produce a reading equal to or greater than 100 percent of the lower explosive limit (LEL, measured as propane) at 2.5 centimeters around the perimeter of a potential leak source as detected by a combustible gas detector using Test Method 21 ( 40 CFR Part 60, Appendix A, as incorporated by reference at LAC 33:III.3003) for determination of volatile organic compound leaks.

2. Design and Operating Requirements. Vapor collection and processing equipment shall be designed and operated to prevent tank truck gauge pressure from exceeding 18 inches of water (4.5 kPa) and prevent vacuum from exceeding 6 inches of water (1.5 kPa).

3. The vapor collection system will be inspected annually.

a. If the administrative authority determines that there is an excessive number of leaks during any given test by the terminal operator or by an administrative authority representative, an increase in the monitoring frequency may be requested.

b. If the vapor collection system fails to pass inspection, any repairs necessary to pass the specified requirements must be made within 15 days of failure.

C. Exemptions. All loading and unloading facilities for crude oil and condensate, for ships and barges and for facilities loading or unloading only liquified petroleum gas are exempt from this Section.

D. Recordkeeping Requirements. The gasoline terminal operator shall maintain records at the facility for at least two years indicating the last time the vapor collection facility passed the requirements specified in Paragraph B.1 of this Section. Items that required repair in order to pass the specified requirements must also be recorded during the annual test procedure.
