NR 665.1085(7)(c)5.5. Maintain a record of the inspection according to s. NR 665.1090 (2).
NR 665.1085(8)(8)The owner or operator who controls air pollutant emissions by using a pressure tank shall meet all of the following requirements.
NR 665.1085(8)(a)(a) Design the tank to not vent to the atmosphere as a result of compression of the vapor headspace in the tank during filling of the tank to its design capacity.
NR 665.1085(8)(b)(b) Equip all tank openings with closure devices designed to operate with no detectable organic emissions determined using the procedure in s. NR 665.1084 (4).
NR 665.1085(8)(c)(c) Whenever hazardous waste is in the tank, operate the tank as a closed system that does not vent to the atmosphere except under any of the following conditions:
NR 665.1085(8)(c)1.1. At those times when opening of a safety device, as defined in s. NR 665.1081, is required to avoid an unsafe condition.
NR 665.1085(8)(c)2.2. At those times when purging of inerts from the tank is required and the purge stream is routed to a closed-vent system and control device designed and operated according to s. NR 665.1088.
NR 665.1085(9)(9)The owner or operator who controls air pollutant emissions by using an enclosure vented through a closed-vent system to an enclosed combustion control device shall meet all of the following requirements:
NR 665.1085(9)(a)(a) Locate the tank inside an enclosure. Design and operate the enclosure according to the criteria for a permanent total enclosure in Method 204—“Criteria for and Verification of a Permanent or Temporary Total Enclosure” of appendix M of 40 CFR part 51, incorporated by reference in s. NR 660.11. The enclosure may have permanent or temporary openings to allow worker access; passage of material into or out of the enclosure by conveyor, vehicles or other mechanical means; entry of permanent mechanical or electrical equipment or direct airflow into the enclosure. Perform the verification procedure for the enclosure in Section 8 of Method 204 initially when the enclosure is first installed and, thereafter, annually.
NR 665.1085(9)(b)(b) Vent the enclosure through a closed-vent system to an enclosed combustion control device that is designed and operated according to the standards for a vapor incinerator, boiler or process heater in s. NR 665.1088.
NR 665.1085(9)(c)(c) Safety devices, as defined in s. NR 665.1081, may be installed and operated as necessary on any enclosure, closed-vent system or control device used to comply with pars. (a) and (b).
NR 665.1085(9)(d)(d) Inspect and monitor the closed-vent system and control device as specified in s. NR 665.1088.
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(10)(b)1.1. The hazardous waste meets the average VO concentration conditions in s. NR 665.1083 (3) (a) at the point of waste origination.
NR 665.1085(10)(b)2.2. The hazardous waste has been treated by an organic destruction or removal process to meet s. NR 665.1083 (3) (b).
NR 665.1085(10)(b)3.3. The hazardous waste meets s. NR 665.1083 (3) (d).
NR 665.1085(11)(11)The owner or operator shall repair each defect detected during an inspection performed according to sub. (3) (d), (5) (c), (6) (c) or (7) (c) as follows:
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.
