Utah Admin. Code R315-265-1053 - Air Emission Standards for Equipment Leaks - Standards: Compressors
(a) Each compressor shall be equipped 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 Subsections
R315-265-1053(h) and R315-265-1053(i).
(b) Each compressor seal system as required
in Subsection R315-265-1053(a) shall be:
(1)
operated with the barrier fluid at a pressure that is always greater than the
compressor stuffing box pressure; or
(2) equipped with a barrier fluid system that
is connected by a closed-vent system to a control device that complies with the
requirements of Section R315-265-1060; or
(3) equipped with a system that purges the
barrier fluid into a hazardous waste stream with no detectable emissions to
atmosphere.
(c) The
barrier fluid may not be a hazardous waste with organic concentrations 10% or
greater by weight.
(d) Each barrier
fluid system as described in Subsections R315-265-1053(a) through
R315-265-1053(c) shall be equipped with a sensor that will detect failure of
the seal system, barrier fluid system, or both.
(e)
(1)
Each sensor as required in Subsection R315-265-1053(d) shall be checked 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.
(2) The owner or
operator shall determine, based on design considerations and operating
experience, a criterion that indicates failure of the seal system, the barrier
fluid system or both.
(f)
If the sensor indicates failure of the seal system, the barrier fluid system,
or both, based on the criterion determined under Subsection
R315-625-1053(e)(2), a leak is detected.
(g)
(1) If
a leak is detected, it shall be repaired as soon as practicable, but before 15
calendar days after it is detected, except as provided in Section
R315-265-1059.
(2) A first attempt
at repair, for example, tightening the packing gland, shall be made no later
than five calendar days after each leak is detected.
(h) A compressor is exempt from the
requirements of Subsections R315-265-1053(a) and R315-265-1053(b) 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
of Section R315-265-1060, except as provided in Subsection
R315-265-1053(i).
(i) Any
compressor that is designated, as described in Subsection R315-265-1064(g)(2),
for no detectable emission as indicated by an instrument reading of less than
500 ppm above background is exempt from the requirements of Subsections
R315-265-1053(a) through R315-265-1053(h) if the compressor:
(1) 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 Subsection
R315-265-1063(c).
(2) is tested for
compliance with Subsection R315-265-1053(i)(1) initially upon designation,
annually, and at other times as requested by the director.
