NR 664.1063(6)(6) When an owner or operator and the department do not agree on whether a piece of equipment contains or contacts a hazardous waste with organic concentrations at least 10% by weight, the procedures in sub. (4) (a) or (b) can be used to resolve the dispute. NR 664.1063(7)(7) Samples used in determining the percent organic content shall be representative of the highest total organic content hazardous waste that is expected to be contained in or contact the equipment. NR 664.1063(8)(8) To determine if pumps or valves are in light liquid service, the vapor pressures of constituents may be obtained from standard reference texts or may be determined by ASTM D2879-86, incorporated by reference in s. NR 660.11. NR 664.1063 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; CR 16-007: am. (4) (b) Register July 2017 No. 739, eff. 8-1-17. NR 664.1064(1)(a)(a) Each owner or operator subject to this subchapter shall comply with this section. NR 664.1064(1)(b)(b) An owner or operator of more than one hazardous waste management unit subject to this subchapter may comply with the recordkeeping requirements for these hazardous waste management units in one recordkeeping system if the system identifies each record by each hazardous waste management unit. NR 664.1064(2)(2) Owners and operators shall record all of the following information in the facility operating record: NR 664.1064(2)(a)1.1. Equipment identification number and hazardous waste management unit identification. NR 664.1064(2)(a)2.2. Approximate locations within the facility (e.g., identify the hazardous waste management unit on a facility plot plan). NR 664.1064(2)(a)4.4. Percent-by-weight total organics in the hazardous waste stream at the equipment. NR 664.1064(2)(a)6.6. Method of compliance with the standard (e.g., “monthly leak detection and repair” or “equipped with dual mechanical seals”). NR 664.1064(2)(c)(c) Where an owner or operator chooses to use test data to demonstrate the organic removal efficiency or total organic compound concentration achieved by the control device, a performance test plan as specified in s. NR 664.1035 (2) (c). NR 664.1064(3)(a)(a) Attach to the leaking equipment a weatherproof and readily visible identification, marked with the equipment identification number, the date evidence of a potential leak was found according to s. NR 664.1058 (1) and the date the leak was detected. NR 664.1064(3)(b)(b) The identification on equipment, except on a valve, may be removed after it has been repaired. NR 664.1064(3)(c)(c) The identification on a valve may be removed after it has been monitored for 2 successive months as specified in s. NR 664.1057 (3) and no leak has been detected during those 2 months. NR 664.1064(4)(a)(a) The instrument and operator identification numbers and the equipment identification number. NR 664.1064(4)(c)(c) The date the leak was detected and the dates of each attempt to repair the leak.
