NR 440.64(3)(e)(e) Loadings of liquid product into gasoline tank trucks shall be limited to vapor-tight gasoline tank trucks using the following procedures:

NR 440.64(3)(e)1.1. The owner or operator shall obtain the vapor tightness documentation described in sub. (6) (b) for each gasoline tank truck which is to be loaded at the affected facility.

NR 440.64(3)(e)2.2. The owner or operator shall require the tank identification number to be recorded as each gasoline tank truck is loaded at the affected facility.

NR 440.64(3)(e)3.a.a. The owner or operator shall cross-check each tank identification number obtained in subd. 2. with the file of tank vapor tightness documentation within 2 weeks after the corresponding tank is loaded., unless either of the following conditions is maintained:

1) If less than an average of one gasoline tank truck per month over the preceding 26 weeks is loaded without vapor tightness documentation, the documentation cross-check shall be performed each quarter.

2) If less than an average of one gasoline tank truck per month over the preceding 52 weeks is loaded without vapor tightness documentation, the documentation cross-check shall be performed semiannually.

NR 440.64(3)(e)3.b.b. If either the quarterly or semiannual cross-check provided in subd. 3. a. 1) or 2) reveals that the conditions in subd. 3. a. 1) or 2) were not maintained, the source shall return to biweekly monitoring until such time as the conditions in subd. 3. a. 1) or 2) are again met.

NR 440.64(3)(e)4.4. The terminal owner or operator shall notify the owner or operator of each nonvapor-tight gasoline tank truck loaded at the affected facility within one week of the documentation cross-check in subd. 3.

NR 440.64(3)(e)5.5. The terminal owner or operator shall take steps assuring that the nonvapor-tight gasoline tank truck will not be reloaded at the affected facility until vapor tightness documentation for that tank is obtained.

NR 440.64(3)(e)6.6. Alternate procedures to those described in subds. 1. to 5. for limiting gasoline tank truck loadings may be used upon application to an approval by the department.

NR 440.64(3)(f)(f) The owner or operator shall act to assure that loadings of gasoline tank trucks at the affected facility are made only into tanks equipped with vapor collection equipment that is compatible with the terminal’s vapor collection system.

NR 440.64(3)(g)(g) The owner or operator shall act to assure that the terminal’s and the tank truck’s vapor collection systems are connected during each loading of a gasoline tank truck at the affected facility. Examples of actions to accomplish this include training drivers in the hookup procedures and posting visible reminder signs at the affected loading racks.

NR 440.64(3)(h)(h) The vapor collection and liquid loading equipment shall be designed and operated to prevent gauge pressure in the delivery tank from exceeding 4,500 pascals (450 mm of water) during product loading. This level is not to be exceeded when measured by the procedures specified in sub. (4) (d).

NR 440.64(3)(i)(i) No pressure-vacuum vent in the bulk gasoline terminal’s vapor collection system may begin to open at a system pressure less than 4,500 pascals (450 mm of water).

NR 440.64(3)(j)(j) Each calendar month the vapor collection system, the vapor processing system and each loading rack handling gasoline shall be inspected during the loading of gasoline tank trucks for total organic compounds liquid or vapor leaks. For purposes of this paragraph detection methods incorporating sight, sound, or smell are acceptable. Each detection of a leak shall be recorded and the source of the leak repaired within 15 calendar days after it is detected.

NR 440.64(4)(a)(a) In conducting the performance tests required in s. NR 440.08, the owner or operator shall use as reference methods and procedures the test methods in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, or other methods and procedures as specified in this subsection, except as provided in s. NR 440.08 (2). The 3-run requirement of s. NR 440.08 (6) does not apply to this section.

NR 440.64(4)(b)(b) Immediately before the performance test required to determine compliance with sub. (3) (b), (c) and (h), the owner or operator shall use Method 21 to monitor for leakage of vapor all potential sources in the terminal’s vapor collection system equipment while a gasoline tank truck is being loaded. The owner or operator shall repair all leaks with readings of 10,000 ppm (as methane) or greater before conducting the performance test.

NR 440.64(4)(c)(c) The owner or operator shall determine compliance with the standards in sub. (3) (b) and (c) as follows:

NR 440.64(4)(c)1.1. The performance test shall be 6 hours long during which at least 300,000 liters of gasoline is loaded. If this is not possible, the test may be continued the same day until 300,000 liters of gasoline is loaded or the test may be resumed the next day with another complete 6-hour period. In the latter case, the 300,000-liter criterion need not be met. However, as much as possible, testing should be conducted during the 6-hour period in which the highest throughput normally occurs.

NR 440.64(4)(c)2.2. If the vapor processing system is intermittent in operation, the performance test shall begin at a reference vapor holder level and shall end at the same reference point. The test shall include at least two startups and shutdowns of the vapor processor. If this does not occur under automatically controlled operations, the system shall be manually controlled.

NR 440.64(4)(c)3.3. The emission rate (E) of total organic compounds shall be computed using the following equation:
