NR 664.1052(4)(4) Each pump equipped with a dual mechanical seal system that includes a barrier fluid system is exempt from sub. (1), provided all of the following requirements are met: NR 664.1052(4)(a)1.1. Operated with the barrier fluid at a pressure that is at all times greater than the pump stuffing box pressure. NR 664.1052(4)(a)2.2. Equipped with a barrier fluid degassing reservoir that is connected by a closed-vent system to a control device that complies with s. NR 664.1060. NR 664.1052(4)(a)3.3. Equipped with a system that purges the barrier fluid into a hazardous waste stream with no detectable emissions to the atmosphere. NR 664.1052(4)(b)(b) The barrier fluid system may not be a hazardous waste with organic concentrations 10% or greater by weight. NR 664.1052(4)(c)(c) Equip each barrier fluid system with a sensor that will detect failure of the seal system, the barrier fluid system or both. NR 664.1052(4)(d)(d) Check each pump by visual inspection, each calendar week, for indications of liquids dripping from the pump seals. NR 664.1052(4)(e)1.1. Check each sensor as described in par. (c) daily, or equip it with an audible alarm and check the alarm monthly to ensure that it is functioning properly. NR 664.1052(4)(e)2.2. Determine, based on design considerations and operating experience, a criterion that indicates failure of the seal system, the barrier fluid system or both. NR 664.1052(4)(f)1.1. If there are indications of liquids dripping from the pump seal or the sensor indicates failure of the seal system, the barrier fluid system or both based on the criterion determined in par. (e) 2., a leak is detected. NR 664.1052(4)(f)2.2. When a leak is detected, repair it as soon as practicable, but not later than 15 calendar days after it is detected, except as provided in s. NR 664.1059. NR 664.1052(4)(f)3.3. Make a first attempt at repair (e.g., relapping the seal) no later than 5 calendar days after each leak is detected. NR 664.1052(5)(5) Any pump that is designated, as described in s. NR 664.1064 (7) (b), for no detectable emissions, as indicated by an instrument reading of less than 500 ppm above background, is exempt from subs. (1), (3) and (4) if the pump meets all of the following requirements: NR 664.1052(5)(a)(a) It has no externally actuated shaft penetrating the pump housing. NR 664.1052(5)(b)(b) It operates with no detectable emissions as indicated by an instrument reading of less than 500 ppm above background measured by the methods specified in s. NR 664.1063 (3). NR 664.1052(5)(c)(c) It is tested for compliance with par. (b) initially upon designation, annually and at other times requested by the department. NR 664.1052(6)(6) If any pump is equipped with a closed-vent system capable of capturing and transporting any leakage from the seal or seals to a control device that complies with s. NR 664.1060, it is exempt from subs. (1) to (5). NR 664.1052 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06. NR 664.1053(1)(1) Equip each compressor with a seal system that includes a barrier fluid system and that prevents leakage of total organic emissions to the atmosphere, except as provided in subs. (8) and (9). NR 664.1053(2)(2) Each compressor seal system as required in sub. (1) shall be one of the following: NR 664.1053(2)(a)(a) Operated with the barrier fluid at a pressure that is at all times greater than the compressor stuffing box pressure. NR 664.1053(2)(b)(b) Equipped with a barrier fluid system that is connected by a closed-vent system to a control device that complies with s. NR 664.1060. NR 664.1053(2)(c)(c) Equipped with a system that purges the barrier fluid into a hazardous waste stream with no detectable emissions to atmosphere. NR 664.1053(3)(3) The barrier fluid may not be a hazardous waste with organic concentrations 10% or greater by weight. NR 664.1053(4)(4) Equip each barrier fluid system described in subs. (1) to (3) with a sensor that will detect failure of the seal system, barrier fluid system or both.
