(1)
No person may allow a vapor-laden delivery vessel subject to OAR 340-232-0085 (Gasoline Delivery Vessel(s))(5) to be filled or emptied unless the delivery vessel:(a)
Is tested annually according to the test Method 32 on file with DEQ, or 40 C.F.R. part 60, EPA Method 27, or California Air Resources Board Test Procedure TP 204.1;(b)
Sustains a pressure change of no more than 750 pascals (3 inches of H2O) in five minutes when pressurized to a gauge pressure of 4,500 pascals (18 inches of H2O) or evacuated to a gauge pressure of 1,500 pascals (6 inches of H2O) during the testing required in subsection (1)(a); and(c)
Displays a valid permit near the Department of Transportation test date markings required by 49 CFR 177.824h, which:(A)
Shows the year and month that the gasoline tank truck last passed the test required in subsections (1)(a) and (b);(B)

The owner or operator of a vapor collection system subject to this regulation must design and operate the vapor collection system and the gasoline loading equipment in a manner that prevents:(a)
Gauge pressure from exceeding 4,500 pascals (18 inches of H2O) and vacuum from exceeding 1,500 pascals (6 inches of H2O) in the gasoline tank truck being loaded;(b)
A reading equal to or greater than 100 percent of the lower explosive limit (LEL, measured as propane) at 2.5 centimeters from all points on the perimeter of a potential leak source when measured by the Method 31 and 33 on file with DEQ, or unloading operations at gasoline dispensing facilities, bulk plants and bulk terminals; and(c)
Visible liquid leaks during loading or unloading operations at gasoline dispensing facilities, bulk plants and bulk terminals.(3)
DEQ may, at any time, monitor a gasoline tank truck, vapor collection system, or vapor control system, by the methods on file with DEQ, to confirm continuing compliance with section (1) or (2).(4)
Recordkeeping and Reporting:(a)
The owner or operator of a source of VOCs subject to this rule must maintain records of all certification testing and repairs. The records must identify the gasoline tank truck, vapor collection system, or vapor control system; the date of the test or repair; and if applicable, the type of repair and the date of retest. The records must be maintained in a legible, readily available condition for at least two years after the date of testing or repair was completed;(b)
Copies of all records and reports under subsection (4)(a) must be submitted to DEQ within 30 days of certification testing.(c)
Persons applying for a permit required by this rule must at the time of application pay a fee of $25.
