Ill. Admin. Code tit. 35, § 721.952 - Standards: Pumps in Light Liquid Service
a) Monitoring.
1) Each pump in light liquid service must be
monitored monthly to detect leaks by the methods specified in Section
721.963(b), except as provided in subsections (d), (e), and (f).
2) Each pump in light liquid service must be
checked by visual inspection each calendar week for indications of liquids
dripping from the pump seal.
b) Leaks.
1) If an instrument reading of 10,000 ppm or
greater is measured, a leak is detected.
2) If there are indications of liquids
dripping from the pump seal, a leak is detected.
c) 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.
d) Each pump equipped with a dual mechanical
seal system that includes a barrier fluid system is exempt from the
requirements of subsection (a), provided the following requirements are met:
1) Each dual mechanical seal system must be
as follows:
A) Operated with the barrier fluid
at a pressure that is at all times greater than the pump stuffing box pressure;
or
B) Equipped with a barrier fluid
degassing reservoir that is connected by a closed-vent system to a control
device that complies with the requirements of Section 721.960; or
C) Equipped with a system that purges the
barrier fluid into a hazardous secondary material stream with no detectable
emissions to the atmosphere.
2) The barrier fluid system must not be a
hazardous secondary material with organic concentrations 10 percent or greater
by weight.
3) Each barrier fluid
system must be equipped with a sensor that will detect failure of the seal
system, the barrier fluid system, or both.
4) Each pump must be checked by visual
inspection, each calendar week, for indications of liquids dripping from the
pump seals.
5) Alarms.
A) Each sensor as described in subsection
(d)(3) must be checked daily or be equipped with an audible alarm that must be
checked monthly to ensure that it is functioning properly.
B) 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.
6) Leaks.
A) If there are indications of liquids
dripping from the pump seal or the sensor indicates failure of the seal system,
the barrier fluid system, or both based on the criterion determined in
subsection (d)(5)(B), a leak is detected.
B) 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.
C) A first attempt at repair (e.g., relapping
the seal) must be made no later than five calendar days after each leak is
detected.
e)
Any pump 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), (c),
and (d) if the pump meets the following requirements:
1) Must have no externally actuated shaft
penetrating the pump housing.
2)
Must operate with no detectable emissions as indicated by an instrument reading
of less than 500 ppm above background as measured by the methods specified in
Section 721.963(c).
3) Must be
tested for compliance with subsection (e)(2) 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.
f) If any pump
is equipped with a closed-vent system capable of capturing and transporting any
leakage from the seal or seals to a control device that complies with the
requirements of Section 721.960, it is exempt from the requirements of
subsections (a) through (e).
