Current through Register Vol. 50, No. 9, September 20, 2024
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.
