Section 335-3-6-.20 - Leaks From Gasoline Tank Trucks And Vapor Collection Systems(1) For the purpose of this Rule, the following definitions apply: (a) "Air Sticker" shall mean a sticker to be affixed to a gasoline tank truck, representing issuance of an Air Permit and that the gasoline tank truck has been demonstrated during its most recent annual vapor leak testing to be leakfree.(b) "Bottom Filling" shall mean the filling of a tank truck or stationary storage tank through an opening that is flush with the tank bottom.(c) "Gasoline" shall mean a petroleum distillate having a Reid vapor pressure of 27.6 kPa (4 psia) or greater that is used as fuel for internal combustion engines.(d) "Gasoline Tank Truck" shall mean tank trucks or trailers equipped with a storage tank and used for the transport of gasoline from sources of supply to stationary storage tanks of gasoline dispensing facilities, bulk gasoline plants or bulk gasoline terminals.(e) "Gasoline Dispensing Facility" shall mean any site where gasoline is dispensed to motor vehicle gasoline tanks from stationary storage tanks.(f) "Bulk Gasoline Terminal" shall mean a gasoline storage facility which receives gasoline from refineries primarily by pipeline, ship, or barge, and delivers gasoline to bulk gasoline plants or to commercial or retail accounts primarily by tank truck; and has a daily throughput of more than 76,000 liters (20,000 gallons) of gasoline in any calendar month.(g) "Bulk Gasoline Plant" shall mean a gasoline storage and distribution facility with an average daily throughput of 76,000 liters (20,000 gallons) or less in any calendar month which receives gasoline from bulk terminals by trailer transport, stores it in tanks, and subsequently dispenses the gasoline via account trucks to local farms, businesses, and gasoline dispensing facilities.(h) "Vapor Collection System" shall mean a vapor transport system which uses direct displacement by the gasoline being transferred to force vapors from the vessel being loaded into either a vessel being unloaded or a vapor control system or vapor holding tank.(i) "Vapor Control System" shall mean a system that prevents release to the atmosphere of at least ninety percent (90%) by weight of organic compounds in the vapors displaced from a vessel during transfer of gasoline.(2) This Rule is applicable to all vapor collection and control systems at bulk plants, bulk terminals, and gasoline dispensing facilities required by Rules 335-3-6-.05, .06 and .07, and to all vapor collection systems on gasoline tank trucks affected by these Rules.(3) After October 1, 1991, no person shall allow a gasoline tank truck subject to this Rule to be filled or emptied unless the gasoline tank truck has: (a) a vapor collection system that meets the test requirements of subparagraph (4)(a) of this Rule; and(b) a valid Department Air Sticker attached and visibly displayed; or,(c) a valid Jefferson County Department of Health Air Sticker attached and visibly displayed.(4)Air Permits for Gasoline Tank Trucks. (a) The owner or operator of a vapor collection system subject to this Rule shall not load or cause to be loaded the said gasoline tank truck without a valid Air Sticker for the gasoline tank truck. An Air Permit and Air Sticker shall be issued by the Department for the gasoline tank truck upon receipt of appropriate documentation from the owner or operator documenting that the gasoline tank truck has been leak checked by the test method referenced in Rule 335-3-6-.16(12)(c) and has during the test sustained a pressure change of no more than 0.750 kPa (3 inches of H20) within five (5) consecutive minutes when pressurized to a gauge pressure of 4.50 kPa (18 inches of H2O) and, when evacuated to a gauge pressure of 1.50 kPa (6 inches of H20) during the testing.(b) Any owner or operator obtaining an Air Permit and Air Sticker from the Jefferson County Department of Health shall not be required to obtain an additional Air Permit and Air Sticker from the Department.(c) The Air Sticker shall be renewed annually upon successful demonstration by the owner or operator that the gasoline tank truck has been leak checked and passed the requirements of subparagraph (a) of this paragraph above.(d) The owner or operator shall display the Air Sticker near the Department of Transportation Certification plate required by 49 CFR 178.340-10 b.(5) The owner or operator of a vapor collection system at a bulk plant, bulk terminal, gasoline dispensing facility or gasoline tank truck subject to this Rule shall: (a) design and operate the vapor collection system and the gasoline loading equipment in a manner that prevents: 1. gauge pressure from exceeding 4.50 kPa (18 inches of H20) and vacuum from exceeding 1.50 kPa (6 inches of H20) in the gasoline tank truck;2. a reading equal to or greater than one hundred percent (100%) 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 referenced in Rule 335-3-6-.16(12) during loading or unloading operations at gasoline dispensing facilities, bulk plants and bulk terminals; and3. avoidable visible liquid leaks during loading or unloading operations at gasoline dispensing facilities, bulk plants and bulk terminals;(b) and within fifteen (15) days, repair and retest a vapor collection or control system that exceeds the limit in subparagraph (a)2. of this paragraph.(6) The Director may, at any time, monitor a gasoline tank truck, vapor collection system or vapor control system to confirm continuing compliance with paragraphs (3), (4) and (5) of this Rule. Monitoring to confirm the continuing existence of leak-tight conditions shall be consistent with the procedures described in Appendix B of the OAQPS Guideline Series document, "Control of Organic Compound Leaks from Gasoline Tank Trucks and Vapor Collection Systems," EPA-450/2-78-051.(7) Each vapor-laden gasoline tank truck shall be designed and maintained to be vapor-tight during loading, unloading operations, and transport with the exception of normal pressure/vacuum venting as required by DOT regulations.
