Chapter NR 440

1) The secondary seal is to be installed above the primary seal so that it completely covers the space between the roof edge and the storage vessel wall except as provided in subd. 2. c.

2) The accumulated area of gaps between the storage vessel wall and the secondary seal may not exceed 21.2 cm2 per meter of storage vessel diameter, and the width of any portion of any gap may not exceed 1.27 cm.

3) There may be no holes, tears, or other openings in the seal or seal fabric.

NR 440.285(4)(b)4.c. c. If a failure that is detected during inspections required in subd. 1 cannot be repaired within 45 days, a 30-day extension may be requested from the department in the inspection report required in sub. (6) (b) 4. An extension request shall include a demonstration of unavailability of alternate storage capacity and a specification of a schedule that will assure that the control equipment will be repaired or the vessel will be emptied as soon as possible.

NR 440.285(4)(b)5. 5. Notify the department 30 days in advance of any gap measurements required by subd. 1. to afford the department opportunity to have an observer present.

NR 440.285(4)(b)6. 6. Visually inspect the external floating roof, the primary seal, secondary seal, and fittings each time the vessel is emptied and degassed.

NR 440.285(4)(b)6.a. a. If the external floating roof has defects, or the primary seal has holes, tears, or other openings in the seal or the seal fabric, the owner or operator shall repair the items as necessary so that none of the conditions specified in this paragraph exist before filling or refilling the storage vessel with VOL.

NR 440.285(4)(b)6.b. b. For all the inspections required by this subdivision, the owner or operator shall notify the department in writing at least 30 days prior to the filling or refilling of each storage vessel to afford the department the opportunity to inspect the storage vessel prior to refilling. If the inspection required by this subdivision is not planned and the owner or operator could not have known about the inspection 30 days in advance of refilling the storage vessel, the owner or operator shall notify the department at least 7 days prior to the refilling of the storage vessel. Notification shall be made by telephone immediately followed by written documentation demonstrating why the inspection was unplanned. Alternatively, this notification including the written documentation may be made in writing and sent by express mail so that it is received by the department at least 7 days prior to the refilling.

NR 440.285(4)(c) (c) The owner or operator of each source that is equipped with a closed vent system and control device as required in sub. (3) (a) 3. or (b) 2. (other than a flare) is exempt from s. NR 440.08 and shall meet the following requirements:

NR 440.285(4)(c)1. 1. Submit for approval by the administrator as an attachment to the notification required by s. NR 440.07 (1) (a), or if the facility is exempt from s. NR 440.07 (1) (a), an operating plan containing the following information:
