NR 661.1053(5)(5)
NR 661.1053(5)(a)(a) Each sensor as required in sub. (4) shall be checked by the remanufacturer or other person daily or shall be equipped with an audible alarm that shall be checked monthly to ensure that it is functioning properly unless the compressor is located within the boundary of an unmanned plant site, in which case the sensor shall be checked daily.
NR 661.1053(5)(b)(b) The 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 661.1053(6)(6)If the sensor indicates failure of the seal system, the barrier fluid system, or both based on the criterion determined under sub. (5) (b), a leak is detected.
NR 661.1053(7)(7)
NR 661.1053(7)(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 under s. NR 661.1059.
NR 661.1053(7)(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 661.1053(8)(8)A compressor is exempt from the requirements under subs. (1) and (2) if it is equipped with a closed-vent system capable of capturing and transporting any leakage from the seal to a control device that complies with the requirements specified in s. NR 661.1060, except as provided in sub. (9).
NR 661.1053(9)(9)Any compressor that is designated, as described in s. NR 661.1064 (7) (b), for no detectable emissions as indicated by an instrument reading of less than 500 ppm above background is exempt from subs. (1) to (8) if the compressor meets all of the following requirements:
NR 661.1053(9)(a)(a) Is determined to be operating with no detectable emissions, as indicated by an instrument reading of less than 500 ppm above background, as measured by the method specified in s. NR 661.1063 (3).
NR 661.1053(9)(b)(b) Is tested for compliance with par. (a) initially upon designation, annually, and at other times as requested by the department.

NR 661.1054NR 661.1054Standards: pressure relief devices in gas/vapor service.
NR 661.1054(1)(1)Except during pressure releases, each pressure relief device in gas or vapor service shall be operated with no detectable emissions, as indicated by an instrument reading of less than 500 ppm above background, as measured by the method specified in s. NR 661.1063 (3).
NR 661.1054(2)(2)
NR 661.1054(2)(a)(a) After each pressure release, the pressure relief device shall be returned to a condition of no detectable emissions, as indicated by an instrument reading of less than 500 ppm above background, as soon as practicable, but no later than 5 calendar days after each pressure release, except as provided in s. NR 661.1059.
NR 661.1054(2)(b)(b) No later than 5 calendar days after the pressure release, the pressure relief device shall be monitored to confirm the condition of no detectable emissions, as indicated by an instrument reading of less than 500 ppm above background, as measured by the method specified in s. NR 661.1063 (3).
NR 661.1054(3)(3)Any pressure relief device that is equipped with a closed-vent system capable of capturing and transporting leakage from the pressure relief device to a control device as described in s. NR 661.1060 is exempt from the requirements under subs. (1) and (2).

NR 661.1055NR 661.1055Standards: sampling connection systems.
NR 661.1055(1)(1)Each sampling connection system shall be equipped with a closed-purge, closed-loop, or closed-vent system. This system shall collect the sample purge for return to the process or for routing to the appropriate treatment system. Gases displaced during filling of the sample container are not required to be collected or captured.
NR 661.1055(2)(2)Each closed-purge, closed-loop, or closed-vent system as required in sub. (1) shall meet one of the following requirements:
NR 661.1055(2)(a)(a) Return the purged process fluid directly to the process line.
NR 661.1055(2)(b)(b) Collect and recycle the purged process fluid.
NR 661.1055(2)(c)(c) Be designed and operated to capture and transport all the purged process fluid to a material management unit that complies with the applicable requirements specified in ss. NR 661.1084 to 664.1086 or a control device that complies with the requirements specified in s. NR 661.1060.
NR 661.1055(3)(3)In-situ sampling systems and sampling systems without purges are exempt from the requirements under subs. (1) and (2).
