NR 664.1086(4)(c)2.a.a. For the purpose of meeting the requirements of this section, an empty container as defined in s. NR 661.0007 (2) may be open to the atmosphere at any time (i.e., covers and closure devices are not required to be secured in the closed position on an empty container). NR 664.1086(4)(c)2.b.b. In the case when discrete quantities or batches of material are removed from the container but the container does not meet the conditions to be an empty container in s. NR 661.0007 (2), promptly secure the closure devices in the closed position and install covers, as applicable to the container, upon the completion of a batch removal after which no additional material will be removed from the container within 15 minutes or the person performing the unloading operation leaves the immediate vicinity of the container, whichever condition occurs first. NR 664.1086(4)(c)3.3. Opening of a closure device or cover is allowed when access inside the container is needed to perform routine activities other than transfer of hazardous waste. Examples of those activities include those times when a worker needs to open a port to measure the depth of or sample the material in the container, or when a worker needs to open a manhole hatch to access equipment inside the container. After completing the activity, promptly secure the closure device in the closed position or reinstall the cover, as applicable to the container. NR 664.1086(4)(c)4.4. Opening of a spring-loaded, pressure-vacuum relief valve, conservation vent or similar type of pressure relief device which vents to the atmosphere is allowed during normal operations for the purpose of maintaining the internal pressure of the container according to the container design specifications. Design the device to operate with no detectable organic emission when the device is secured in the closed position. Establish the settings at which the device opens such that the device remains in the closed position whenever the internal pressure of the container is within the internal pressure operating range determined by the owner or operator based on container manufacturer recommendations, applicable rules, fire protection and prevention codes, standard engineering codes and practices or other requirements for the safe handling of flammable, ignitable, explosive, reactive or hazardous materials. Examples of normal operating conditions that may require these devices to open are during those times when the internal pressure of the container exceeds the internal pressure operating range for the container as a result of loading operations or diurnal ambient temperature fluctuations. NR 664.1086(4)(c)5.5. Opening of a safety device, as defined in s. NR 665.1081, is allowed at any time conditions require doing so to avoid an unsafe condition. NR 664.1086(4)(d)(d) Inspect containers using Container Level 2 controls and their covers and closure devices as follows: NR 664.1086(4)(d)1.1. In the case when hazardous waste is already in the container at the time the owner or operator first accepts possession of the container at the facility and the container is not emptied within 24 hours after the container is accepted at the facility (i.e., does not meet the conditions for an empty container in s. NR 661.0007 (2)), the owner or operator shall visually inspect the container and its cover and closure devices to check for visible cracks, holes, gaps or other open spaces into the interior of the container when the cover and closure devices are secured in the closed position. The owner or operator shall conduct the container visual inspection on or before the date that the container is accepted at the facility (i.e., the date the container becomes subject to the subchapter CC container standards in this subchapter). For purposes of this requirement, the date of acceptance is the date of signature that the facility owner or operator enters on item 20 of the uniform hazardous waste manifest (EPA forms 8700-22 and 8700-22A), as required in s. NR 664.0071. If a defect is detected, the owner or operator shall repair the defect in accordance with the requirements of subd. 3. NR 664.1086(4)(d)2.2. In the case when a container used for managing hazardous waste remains at the facility for a period of one year or more, visually inspect the container and its cover and closure devices initially and thereafter, at least once every 12 months, to check for visible cracks, holes, gaps or other open spaces into the interior of the container when the cover and closure devices are secured in the closed position. If a defect is detected, repair the defect according to subd. 3. NR 664.1086(4)(d)3.3. When a defect is detected for the container, cover or closure devices, make first efforts at repair of the defect no later than 24 hours after detection, and complete the repair as soon as possible but no later than 5 calendar days after detection. If repair of a defect cannot be completed within 5 calendar days, remove the hazardous waste from the container and do not use the container to manage hazardous waste until the defect is repaired. NR 664.1086(5)(a)(a) A container using Container Level 3 controls is one of the following: NR 664.1086(5)(a)1.1. A container that is vented directly through a closed-vent system to a control device according to par. (b) 2. NR 664.1086(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 664.1086(5)(b)(b) Meet the following requirements, as applicable to the type of air emission control equipment selected: NR 664.1086(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 664.1086(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 664.1086(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 664.1087. NR 664.1086(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 664.1086(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 664.1086(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 664.1083 (4) as follows: NR 664.1086(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 664.1086(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 664.1086(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 664.1086(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 664.1086(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.
