Section 665.1053. Standards: compressors.

 

(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) .

(2)  Each compressor seal system as required in sub. (1) shall be one of the following:

(a) Operated with the barrier fluid at a pressure that is at all times greater than the compressor stuffing box pressure.

(b) Equipped with a barrier fluid system that is connected by a closed-vent system to a control device that complies with s. NR 665.1060 .

(c) Equipped with a system that purges the barrier fluid into a hazardous waste stream with no detectable emissions to atmosphere.

(3)  The barrier fluid may not be a hazardous waste with organic concentrations 10 percent or greater by weight.

(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.

(5)  

(a) Check each sensor required in sub. (4) daily, or equip it with an audible alarm and check the alarm monthly to ensure it is functioning properly, unless the compressor is located within the boundary of an unmanned plant site, in which case check the sensor daily.

(b) Determine, based on design considerations and operating experience, a criterion that indicates failure of the seal system, the barrier fluid system or both.

(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.

(7)  

(a) 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 665.1059 .

(b) Make a first attempt at repair (e.g., tightening the packing gland) no later than 5 calendar days after each leak is detected.

(8)  A compressor is exempt from 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 s. NR 665.1060 , except as provided in sub. (9) .

(9)  Any compressor that is designated, as described in s. NR 665.1064 (7) (b) , for no detectable emission 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:

(a) It is determined to be operating with no detectable emissions, as indicated by an instrument reading of less than 500 ppm above background, measured by the method specified in s. NR 665.1063 (3) .

(b) It is tested for compliance with par. (a) initially upon designation, annually and at other times requested by the department.
