25 Pa. Code § 129.62. General standards for bulk gasoline terminals, bulk gasoline plants and small gasoline storage tanks.

§ 129.62. General standards for bulk gasoline terminals, bulk gasoline plants and small gasoline storage tanks.

 (a)  Gasoline may not be spilled or discarded in sewers or stored in open containers or handled in a manner that would result in uncontrolled evaporation to the atmosphere.

 (b)  An owner or operator of a bulk gasoline plant, bulk gasoline terminal, tank truck or trailer or stationary storage tank to which §  129.59, §  129.60(b) or (c) or §  129.61 (relating to bulk gasoline terminals; bulk gasoline plants; and small gasoline storage tank control (Stage I control)) apply may not permit the transfer of gasoline between the tank truck or trailer and a stationary storage tank unless the following conditions are met:

   (1)  The vapor balance system is in good working order and is designed and operated in a manner that prevents:

     (i)   Gauge pressure from exceeding 18 inches of H2O (4500 pascals) and vacuum from exceeding 6 inches of water (1500 pascals) in the gasoline tank truck.

     (ii)   A reading equal to or greater than 100% of the lower explosive limit—LEL, measured as propane—at 1 inch from points on the perimeter of a potential leak source when measured by the method referenced in §  139.14 (relating to emissions of VOCs) during loading or unloading operations at small gasoline storage tanks, bulk plants and bulk terminals.

     (iii)   Avoidable liquid leaks during loading or unloading operations at small gasoline storage tanks, bulk plants and bulk terminals.

   (2)  A truck, vapor balance system or vapor disposal system, if applicable, that exceeds the limits in paragraph (1) is repaired and retested within 15 days.

   (3)  There are no visually- or audibly-detectable leaks in the tank truck’s or trailer’s pressure/vacuum relief valves and hatch covers, the truck tanks or storage tanks, or associated vapor and liquid lines during loading or unloading.

   (4)  The pressure and vacuum relief valves on storage vessels and tank trucks or trailers are set to release at no less than .7 psig (4.8 kilopascals) of pressure or .3 psig (2.1 kilopascals) of vacuum or the highest allowable pressure and vacuum as specified in State or local fire codes, the National Fire Prevention Association guidelines or other National consensus standards acceptable to the Department. Upon demonstration by the owner or operator of an underground small gasoline storage tank that the vapor balance system specified in paragraph (1) will achieve a 90% vapor recovery efficiency without a pressure and vacuum relief valve and that an interlock system, sufficient to ensure connection of the vapor recovery line prior to delivery of the gasoline, will be used—no pressure and vacuum relief valve is required. The vacuum setting on the pressure and vacuum relief valve on an underground storage tank may be set at the lowest vacuum setting which is sufficient to keep the vent closed at zero pressure and vacuum.

 (c)  A person may not allow a gasoline tank truck subject to §  129.59, §  129.60 or §  129.61 to be filled or emptied in a geographic area specified in §  129.61(a) unless the gasoline tank truck:

   (1)  Has been tested by the owner or operator within the immediately preceding 12 months in accordance with §  139.14.

   (2)  Sustains a pressure change of no more than 750 pascals (3 inches of H2O) in 5 minutes when pressurized to a gauge pressure of 18 inches of H2O (4,500 pascals) or evacuated to a gauge pressure of 6 inches of H2O (1,500 pascals) during the testing required in paragraph (1).

   (3)  Is repaired by the owner or operator and retested within 15 days of testing if it does not meet the criteria in paragraph (2).

   (4)  Displays a clear marking near the Department of Transportation Certification plate required by 49 CFR 178.340-10b (relating to certification), which shows the most recent date upon which the gasoline tank truck passed the test required in this subsection.

 (d)  Reporting and recordkeeping shall be as follows:

   (1)  The owner or operator of a source of VOCs subject to subsection (c) shall maintain records of certification testing and repairs. The records shall 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 shall be maintained in a legible, readily-available condition for 1 year after the date the testing or repair was completed.

   (2)  The records of certification tests required by paragraph (1) shall contain:

     (i)   The gasoline tank truck tank serial number.

     (ii)   The initial test pressure and the time of the reading.

     (iii)   The final test pressure and the time of the reading.

     (iv)   The initial test vacuum and the time of the reading.

     (v)   The final test vacuum and the time of the reading.

     (vi)   At the top of each report page, the company name and the date and location of the tests on that page.

     (vii)   The name and title of the person conducting the test.

   (3)  Copies of records and reports under this subsection shall be made available to the Department upon verbal or written request at any reasonable time. A copy of the test results for each gasoline tank shall be kept with the truck.

 (e)  Gasoline tank trucks with a rated capacity of less than 4,800 gallons are exempt from subsections (c) and (d).
