NR 661.1057(7)(a)(a) The remanufacturer or other person that stores or treats the hazardous secondary material determines that the valve is unsafe to monitor because monitoring personnel would be exposed to an immediate danger as a consequence of complying with sub. (1). NR 661.1057(7)(b)(b) The remanufacturer or other person that stores or treats the hazardous secondary material adheres to a written plan that requires monitoring of the valve as frequently as practicable during safe-to-monitor times. NR 661.1057(8)(8) Any valve that is designated, as described in s. NR 661.1064 (8) (b), as a difficult-to-monitor valve is exempt from the requirements under sub. (1) if all of the following requirements are met: NR 661.1057(8)(a)(a) The remanufacturer or other person that stores or treats the hazardous secondary material determines that the valve cannot be monitored without elevating the monitoring personnel more than 2 meters above a support surface. NR 661.1057(8)(b)(b) The hazardous secondary material management unit within which the valve is located was in operation before January 13, 2015. NR 661.1057(8)(c)(c) The owner or operator of the valve follows a written plan that requires monitoring of the valve at least once per calendar year. NR 661.1057 HistoryHistory: CR 19-082: cr.

NR 661.1058NR 661.1058 Standards: pumps and valves in heavy liquid service, pressure relief devices in light liquid or heavy liquid service, and flanges and other connectors. NR 661.1058(1)(1) Pumps and valves in heavy liquid service, pressure relief devices in light liquid or heavy liquid service, and flanges and other connectors shall be monitored within 5 days by the method specified in s. NR 661.1063 (2) if evidence of a potential leak is found by visual, audible, olfactory, or any other detection method. NR 661.1058(2)(2) If an instrument reading of 10,000 ppm or greater is measured, a leak is detected. NR 661.1058(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 661.1058(3)(b)(b) The first attempt at repair shall be made no later than 5 calendar days after each leak is detected. NR 661.1058(5)(5) Any connector that is inaccessible or is ceramic or ceramic-lined, such as porcelain, glass, or glass-lined, is exempt from the monitoring requirements under sub. (1) and from the recordkeeping requirements specified in s. NR 661.1064. NR 661.1058 HistoryHistory: CR 19-082: cr. Register August 2020 No. 776, eff. 9-1-20. NR 661.1059(1)(1) Delay of repair of equipment for which leaks have been detected is allowed if the repair is technically infeasible without a hazardous secondary material management unit shutdown. In such a case, repair of this equipment shall occur before the end of the next hazardous secondary material management unit shutdown. NR 661.1059(2)(2) Delay of repair of equipment for which leaks have been detected is allowed for equipment that is isolated from the hazardous secondary material management unit and that does not continue to contain or contact hazardous secondary material with organic concentrations at least 10 percent by weight. NR 661.1059(3)(3) Delay of repair for valves is allowed if all of the following conditions are met: NR 661.1059(3)(a)(a) The remanufacturer or other person that stores or treats the hazardous secondary material determines that emissions of purged material resulting from immediate repair are greater than the emissions likely to result from delay of repair. NR 661.1059(3)(b)(b) When repair procedures are affected, the purged material is collected and destroyed or recovered in a control device complying with s. NR 661.1060. NR 661.1059(4)(4) Delay of repair for pumps is allowed if all of the following conditions are met: NR 661.1059(4)(a)(a) Repair requires the use of a dual mechanical seal system that includes a barrier fluid system. NR 661.1059(4)(b)(b) Repair is completed as soon as practicable, but not later than 6 months after the leak was detected. NR 661.1059(5)(5) Delay of repair beyond a hazardous secondary material management unit shutdown is allowed for a valve if valve assembly replacement is necessary during the hazardous secondary material management unit shutdown, valve assembly supplies have been depleted, and valve assembly supplies had been sufficiently stocked before the supplies were depleted. Delay of repair beyond the next hazardous secondary material management unit shutdown is not allowed unless the next hazardous secondary material management unit shutdown occurs sooner than 6 months after the first hazardous secondary material management unit shutdown.
