S.C. Code Regs. 61-79.261.BB.1053 - 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 paragraphs (h) and (i) of this
section.
(b) Each compressor seal
system as required in paragraph (a) of this section shall be:
(1) Operated with the barrier fluid at a
pressure that is at all times greater than the compressor stuffing box
pressure;
(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 261.1060; 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 ten (10) percent or greater by
weight.
(d) Each barrier fluid
system as described in paragraphs (a) through (c) of this section 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 paragraph (d)
of this section shall be checked daily or shall 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 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 paragraph (e)(2) of this section, a leak is
detected.
(g)
(1) When a leak is detected, it shall be
repaired as soon as practicable, but not later than fifteen (15) calendar days
after it is detected, except as provided in section 261.1059.
(2) A first attempt at repair (e.g.,
tightening the packing gland) shall be made no later than five (5) calendar
days after each leak is detected.
(h) A compressor is exempt from the
requirements of paragraphs (a) and (b) of this section 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
261.1060, except as provided in paragraph (i) of this section.
(i) Any compressor that is designated, as
described in section 261.1064(g)(2), for no detectable emissions as indicated
by an instrument reading of less than five hundred (500) ppm above background
is exempt from the requirements of paragraphs (a) through (h) of this section
if the compressor:
(1) Is determined to be
operating with no detectable emissions, as indicated by an instrument reading
of less than five hundred (500) ppm above background, as measured by the method
specified in section 261.1063(c).
(2) Is tested for compliance with paragraph
(i)(1) of this section initially upon designation, annually, and at other times
as requested by the Department.
