NR 665.1085(10)(10) The owner or operator shall transfer hazardous waste to a tank subject to this section according to all of the following requirements: NR 665.1085(10)(a)(a) Except as provided in par. (b), transfer hazardous waste to the tank from another tank subject to this section or from a surface impoundment subject to s. NR 665.1086 using continuous hard-piping or another closed system that does not allow exposure of the hazardous waste to the atmosphere. For the purpose of complying with this paragraph, an individual drain system is a closed system when it meets 40 CFR part 63, subpart RR—National Emission Standards for Individual Drain Systems. NR 665.1085(10)(b)(b) Paragraph (a) does not apply when transferring a hazardous waste to the tank under any of the following conditions: NR 665.1085(11)(a)(a) Make first efforts at repair of the defect no later than 5 calendar days after detection, and complete the repair as soon as possible but no later than 45 calendar days after detection except as provided in par. (b). NR 665.1085(11)(b)(b) Repair of a defect may be delayed beyond 45 calendar days if the owner or operator determines that repair of the defect requires emptying or temporary removal from service of the tank and no alternative tank capacity is available at the site to accept the hazardous waste normally managed in the tank. In this case, repair the defect the next time the process or unit that is generating the hazardous waste managed in the tank stops operation. Complete repair of the defect before the process or unit resumes operation. NR 665.1085(12)(12) Following the initial inspection and monitoring of the cover as required by the applicable provisions of this subchapter, subsequent inspection and monitoring may be performed at intervals longer than one year under the following special conditions: NR 665.1085(12)(a)(a) In the case when inspecting or monitoring the cover would expose a worker to dangerous, hazardous or other unsafe conditions, the owner or operator may designate a cover as an “unsafe to inspect and monitor cover” and comply with all of the following requirements: NR 665.1085(12)(a)1.1. Prepare a written explanation for the cover stating the reasons why the cover is unsafe to visually inspect or to monitor, if required. NR 665.1085(12)(a)2.2. Develop and implement a written plan and schedule to inspect and monitor the cover, using the procedures specified in the applicable section of this subchapter, as frequently as practicable during those times when a worker can safely access the cover. NR 665.1085(12)(b)(b) In the case when a tank is buried partially or entirely underground, inspect and monitor, as required by the applicable provisions of this section, only those portions of the tank cover and those connections to the tank (e.g., fill ports, access hatches, gauge wells, etc.) that are located on or above the ground surface.

NR 665.1086(1)(1) This section applies to the control of air pollutant emissions from surface impoundments for which s. NR 665.1083 (2) references the use of this section for the air emission control. NR 665.1086(2)(2) The owner or operator shall control air pollutant emissions from the surface impoundment by installing and operating any of the following: NR 665.1086(2)(b)(b) A cover that is vented through a closed-vent system to a control device according to sub. (4). NR 665.1086(3)(3) The owner or operator who controls air pollutant emissions from a surface impoundment using a floating membrane cover shall meet all of the following requirements: NR 665.1086(3)(a)(a) Equip the surface impoundment with a floating membrane cover designed to meet all of the following specifications: NR 665.1086(3)(a)1.1. Design the floating membrane cover to float on the liquid surface during normal operations and form a continuous barrier over the entire surface area of the liquid. NR 665.1086(3)(a)2.2. Fabricate the cover from a synthetic membrane material that is any of the following: NR 665.1086(3)(a)2.a.a. High density polyethylene (HDPE) with a thickness no less than 2.5 millimeters (mm). NR 665.1086(3)(a)2.b.b. A material or a composite of different materials determined to have both organic permeability properties that are equivalent to those of the material listed in subd. 2. a. and chemical and physical properties that maintain the material integrity for the intended service life of the material. NR 665.1086(3)(a)3.3. Install the cover in a manner such that there are no visible cracks, holes, gaps or other open spaces between cover section seams or between the interface of the cover edge and its foundation mountings. NR 665.1086(3)(a)4.4. Except as provided for in subd. 5., equip each opening in the floating membrane cover with a closure device designed to operate such that when the closure device is secured in the closed position there are no visible cracks, holes, gaps or other open spaces in the closure device or between the perimeter of the cover opening and the closure device.
