Section Env-A 1217.07 - Work Practice Standards for Bulk Gasoline Loading Terminals(a) All displaced vapors and gases shall be vented only to the vapor control system.(b) The terminal owner or operator shall not: (1) Allow gasoline to be discarded in sewers or stored in open containers or handled in any manner that would result in evaporation; or(2) Allow the pressure in the vapor collection system to exceed the tank truck or trailer pressure relief settings.(c) Liquid product shall be loaded only into vapor-tight gasoline trucks.(d) During a loading operation, the terminal owner or operator shall: (1) Obtain the vapor tightness documentation from the tank truck driver for each gasoline tank truck that is to be loaded at the bulk gasoline terminal loading rack;(2) Require the tank identification number to be recorded as each gasoline tank truck is loaded at the terminal;(3) Cross-check each tank identification number obtained in (d)(2), above, with the file of tank vapor tightness documentation within 2 weeks after the corresponding tank is loaded;(4) Notify the owner or operator of each non-vapor-tight gasoline tank truck loaded at the bulk gasoline terminal loading rack within 3 weeks after the loading has occurred that the truck is not vapor-tight; and(5) Develop and follow procedures to assure that no gasoline tank truck deemed to be non-vapor-tight under (d)(1)(2) and (3), above, will be reloaded until vapor tightness documentation for that tank is obtained.(e) The terminal owner or operator shall take measures to ensure that: (1) Loadings of gasoline tank trucks at the bulk gasoline terminal loading rack are made only into tanks equipped with vapor collection equipment that is compatible with the terminal's vapor collection system; and(2) The vapor collection systems of the terminal and tank truck are connected at the bulk gasoline tank truck at the bulk gasoline terminal loading racks during each loading.(f) The vapor collection and liquid loading equipment shall be designed and operated to prevent gauge pressure in the delivery tank from exceeding 4,500 Pa, equivalent to 0.65 psi or 18 in. of water, during product loading.(g) Measurement of the gauge pressure shall be as follows: (1) A pressure measuring instrument, such as a liquid manometer or equivalent, capable of measuring up to 500 mm mercury, equivalent to 20 in. water, gauge pressure, with a precision of +2.5 mm mercury, equivalent to +20 in. water, shall be calibrated and installed;(2) The pressure measuring instrument shall be connected to a pressure tap in the vapor collection system of the terminal, located as close as possible to the connection with the gasoline tank truck; and(3) During the performance test, gauge pressures shall be recorded at least once for each loading position according to the following procedure: a. The pressure shall be recorded every 5 minutes during the loading of a gasoline tank truck; andb. The highest instantaneous pressure that occurs during each loading shall be recorded.(h) No pressure-vacuum vent in the bulk gasoline loading terminal's vapor collection system shall begin to open at a system pressure less than 4500 Pa, equivalent to 0.65 psi.(i) At least once each calendar month, the vapor collection system, vapor control system, and each loading rack handling gasoline shall be inspected by visual, sound, or odor detection methods for total liquid or vapor organic compound leaks during the loading of gasoline tank trucks.(j) Each detection of a leak shall be recorded and the source of the leak repaired within 15 calendar days after it is detected.(k) Loading of outgoing gasoline tank trucks shall be restricted to the use of submerged fill.N.H.
