Utah Admin. Code R315-265-1052 - Air Emission Standards for Equipment Leaks - Standards: Pumps in Light Liquid Service
(a)
(1) Each pump in light liquid service shall
be monitored monthly to detect leaks by the methods specified in Subsection
R315-265-1063(b), except as provided in Subsections R315-265-1052(d),
R315-265-1052(e), and R315-265-1052(f).
(2) Each pump in light liquid service shall
be checked by visual inspection each calendar week for indications of liquids
dripping from the pump seal.
(b)
(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)
(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.
(d) Each pump equipped with a dual mechanical
seal system that includes a barrier fluid system and that meets the following
requirements is exempt from the requirements of Subsection R315-265-1052(a):
(1) Each dual mechanical seal system shall
be:
(i) operated with the barrier fluid at a
pressure that is always greater than the pump stuffing box pressure;
or
(ii) 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 R315-265-1060;
or
(iii) equipped with a system
that purges the barrier fluid into a hazardous waste stream with no detectable
emissions to the atmosphere.
(2) The barrier fluid system may not be a
hazardous waste with organic concentrations 10% or greater by weight.
(3) Each barrier fluid system shall be
equipped with a sensor that will detect failure of the seal system, the barrier
fluid system or both.
(4) Each pump
shall be checked by visual inspection, each calendar week, for indications of
liquids dripping from the pump seals.
(5)
(i) Each
sensor as described in Subsection R315-265-1052(d)(3) shall be checked daily or
be equipped with an audible alarm that shall be checked monthly to ensure that
it is functioning properly.
(ii)
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.
(6)
(i) 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 R315-265-1052(d)(5)(ii), a leak is
detected.
(ii) 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.
(iii) A first
attempt at repair, for example, relapping the seal, shall be made no later than
five calendar days after each leak is detected.
(e) Any pump that is designated, as described
in Subsection R315-265-1064(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 R315-265-1052(a), R315-265-1052(c), and
R315-265-1052(d) if the pump meets the following requirements:
(1) Shall have no externally actuated shaft
penetrating the pump housing.
(2)
Shall 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 Subsection R315-265-1063(c).
(3) Shall be tested for compliance with
Subsection R315-265-1052(e)(2) initially upon designation, annually, and at
other times as requested by the director.
(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 R315-265-1060, it is exempt from the requirements of Subsections
R315-265-1052(a) through R315-265-1052(e).
