NR 665.1087(5)(a)2.2. A container that is vented inside an enclosure which is exhausted through a closed-vent system to a control device according to par. (b) 1. and 2. NR 665.1087(5)(b)(b) Meet the following requirements, as applicable to the type of air emission control equipment selected: NR 665.1087(5)(b)1.1. Design and operate the container enclosure according to the criteria for a permanent total enclosure in Method 204—“Criteria for and Verification of a Permanent or Temporary Total Enclosure” in 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 containers through the enclosure by conveyor 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 665.1087(5)(c)(c) Safety devices, as defined in s. NR 665.1081, may be installed and operated as necessary on any container, enclosure, closed-vent system or control device used to comply with par. (a). NR 665.1087(5)(d)(d) If using Container Level 3 controls according to this subchapter, inspect and monitor the closed-vent systems and control devices as specified in s. NR 665.1088. NR 665.1087(5)(f)(f) Transfer hazardous waste in or out of a container using Container Level 3 controls in such a manner as to minimize exposure of the hazardous waste to the atmosphere, to the extent practical, considering the physical properties of the hazardous waste and good engineering and safety practices for handling flammable, ignitable, explosive, reactive or other hazardous materials. Examples of container loading procedures that meet this paragraph include using a submerged-fill pipe or other submerged-fill method to load liquids into the container, a vapor-balancing system or a vapor-recovery system to collect and control the vapors displaced from the container during filling operations, or a fitted opening in the top of a container through which the hazardous waste is filled and subsequently purging the transfer line before removing it from the container opening. NR 665.1087(6)(6) Hazardous materials packaging requirements. For the purpose of compliance with sub. (3) (a) 1. or (4) (a) 1., use containers that meet the applicable U.S. department of transportation (DOT) regulations on packaging hazardous materials for transportation as follows: NR 665.1087(6)(b)(b) Hazardous waste is managed in the container according to the applicable requirements in 49 CFR part 107, subpart B—Exemptions; 49 CFR part 172—Hazardous Materials Table, Special Provisions, Hazardous Materials Communications, Emergency Response Information, and Training Requirements; 49 CFR part 173—Shippers—General Requirements for Shipments and Packages and 49 CFR part 180—Continuing Qualification and Maintenance of Packagings. NR 665.1087(7)(7) Procedure for determining no detectable organic emissions. To determine compliance with the no detectable organic emissions requirements of sub. (4) (a) 2., use the procedure in s. NR 665.1084 (4) as follows: NR 665.1087(7)(a)(a) Check each potential leak interface (i.e., a location where organic vapor leakage could occur) on the container, its cover and associated closure devices, as applicable to the container. Potential leak interfaces that are associated with containers include, but are not limited to, the interface of the cover rim and the container wall, the periphery of any opening on the container or container cover and its associated closure device and the sealing seat interface on a spring-loaded, pressure-relief valve. NR 665.1087(7)(b)(b) Perform the test when the container is filled with a material having a volatile organic concentration representative of the range of volatile organic concentrations for the hazardous wastes expected to be managed in this type of container. During the test, secure the container cover and closure devices in the closed position. NR 665.1087(8)(8) Procedure for determining a container to be vapor-tight. To determine compliance with the vapor-tight container requirement of sub. (4) (a) 3., use the following procedure: NR 665.1087(8)(b)(b) Use a pressure measurement device that has a precision of ±2.5 mm water and is capable of measuring above the pressure at which the container is to be tested for vapor tightness. NR 665.1087(8)(c)(c) If the test results determined by Method 27 indicate that the container sustains a pressure change less than or equal to 750 Pascals within 5 minutes after it is pressurized to a minimum of 4,500 Pascals, the container is vapor-tight.

NR 665.1088NR 665.1088 Standards: closed-vent systems and control devices. NR 665.1088(1)(1) This section applies to each closed-vent system and control device installed and operated by the owner or operator to control air emissions according to the standards of this subchapter. NR 665.1088(2)(2) The closed-vent system shall meet all of the following requirements: NR 665.1088(2)(a)(a) The closed-vent system shall route the gases, vapors and fumes emitted from the hazardous waste in the waste management unit to a control device that meets sub. (3). NR 665.1088(2)(c)(c) In the case when the closed-vent system includes bypass devices that could be used to divert the gas or vapor stream to the atmosphere before entering the control device, equip each bypass device with either a flow indicator as specified in subd. 1. or a seal or locking device as specified in subd. 2. For the purpose of complying with this paragraph, low leg drains, high point bleeds, analyzer vents, open-ended valves or lines, spring-loaded pressure relief valves and other fittings used for safety purposes are not bypass devices. NR 665.1088(2)(c)1.1. If a flow indicator is used to comply with this paragraph, install the indicator at the inlet to the bypass line used to divert gases and vapors from the closed-vent system to the atmosphere at a point upstream of the control device inlet. For this paragraph, a flow indicator means a device which indicates the presence of either gas or vapor flow in the bypass line. NR 665.1088(2)(c)2.2. If a seal or locking device is used to comply with this paragraph, place the device on the mechanism by which the bypass device position is controlled (e.g., valve handle, damper lever) when the bypass device is in the closed position such that the bypass device cannot be opened without breaking the seal or removing the lock. Examples of the devices include, but are not limited to, a car-seal or a lock-and-key configuration valve. Visually inspect the seal or closure mechanism at least once every month to verify that the bypass mechanism is maintained in the closed position.
