Ill. Admin. Code tit. 35, § 721.953 - Standards: Compressors
a) Each
compressor must 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 (h) and (i).
b) Each compressor seal system as required in
subsection (a) must be:
1) Operated with the
barrier fluid at a pressure that is at all times 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 721.960;
or
3) Equipped with a system that
purges the barrier fluid into a hazardous secondary material stream with no
detectable emissions to atmosphere.
c) The barrier fluid must not be a hazardous
secondary material with organic concentrations 10 percent or greater by
weight.
d) Each barrier fluid
system, as described in subsections (a) through (c), must be equipped with a
sensor that will detect failure of the seal system, barrier fluid system, or
both.
e) Inspections.
1) Each sensor as required in subsection (d)
must be checked daily or must be equipped with an audible alarm that must 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 must be checked daily.
2)
The remanufacturer or other person that stores or treats the hazardous
secondary material must 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 (e)(2), a leak is detected.
g) Repairs.
1) When a leak is detected, it must be
repaired as soon as practicable, but not later than 15 calendar days after it
is detected, except as provided in Section 721.959.
2) A first attempt at repair (e.g.,
tightening the packing gland) must be made no later than five calendar days
after each leak is detected.
h) A compressor is exempt from the
requirements of subsections (a) and (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 721.960, except
as provided in subsection (i).
i)
Any compressor that is designated, as described in Section 721.964(g)(2), for
no detectable emissions as indicated by an instrument reading of less than 500
ppm above background is exempt from the requirements of subsections (a) through
(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
Section 721.963(c).
2) Is tested
for compliance with subsection (i)(1) initially upon designation, annually, and
at other times as requested by the Agency. The Agency must request any
compliance testing at times other than annually in writing to the
remanufacturer or other person that stores or treats the hazardous secondary
material.
