(4) to (6), the remanufacturer or other person shall monitor each pump in light liquid service monthly to detect leaks by the methods specified in s. NR 661.1063 (2). NR 661.1052(1)(b)(b) The remanufacturer or other person shall check each pump in light liquid service by visual inspection each calendar week for indications of liquids dripping from the pump seal. NR 661.1052(2)(a)(a) If an instrument reading of 10,000 ppm or greater is measured, a leak is detected. NR 661.1052(2)(b)(b) If there are indications of liquids dripping from the pump seal, a leak is detected. NR 661.1052(3)(a)(a) When a leak is detected, it shall be repaired as soon as practicable, but not later than 15 calendar days after it is detected, except as provided in s. NR 661.1059. NR 661.1052(3)(b)(b) A first attempt at repair, such as tightening the packing gland, shall be made no later than 5 calendar days after each leak is detected. NR 661.1052(4)(4) Each pump equipped with a dual mechanical seal system that includes a barrier fluid system is exempt from the requirements under sub. (1), provided all of the following requirements are met: NR 661.1052(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 661.1052(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 the requirements specified in s. NR 661.1060. NR 661.1052(4)(a)3.3. Equipped with a system that purges the barrier fluid into a hazardous secondary material stream with no detectable emissions to the atmosphere. NR 661.1052(4)(b)(b) The barrier fluid system may not be a hazardous secondary material with organic concentrations 10 percent or greater by weight. NR 661.1052(4)(c)(c) Each barrier fluid system shall be equipped with a sensor that will detect failure of the seal system, the barrier fluid system, or both. NR 661.1052(4)(d)(d) Each pump shall be checked the remanufacturer or other person by visual inspection, each calendar week, for indications of liquids dripping from the pump seals. NR 661.1052(4)(e)1.1. Each sensor as described in par. (c) shall be checked by the remanufacturer or other person daily or be equipped with an audible alarm that shall be checked monthly to ensure that it is functioning properly. NR 661.1052(4)(e)2.2. A remanufacturer or other person that stores or treats the hazardous secondary material shall determine, based on design considerations and operating experience, a criterion that indicates failure of the seal system, the barrier fluid system, or both. NR 661.1052(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.
