Current through Register Vol. 48, No. 9, September 27, 2024
(a)
(1)
Each pump in light liquid service shall be monitored monthly to detect leaks by
the methods specified in 264.1063(b), except as provided in paragraphs (d),
(e), and (f) of this section.
(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)
When a leak is detected, it shall be repaired as soon as practicable, but not
later than 15 calendar days after it is detected, except as provided in
264.1059.
(2) A first attempt at
repair (e.g., tightening the packing gland) shall be made no later than 5
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 paragraph (a) of this section, provided the following
requirements are met:
(1) Each dual mechanical
seal system must be:
(i) Operated with the
barrier fluid at a pressure that is at all times 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 264.1060,
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 must not be a
hazardous waste 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)
(i) Each sensor as described in paragraph
(d)(3) of this section must be checked daily or be equipped with an audible
alarm that must be checked monthly to ensure that it is functioning
properly.
(ii) The owner or
operator 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)
(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 paragraph (d)(5)(ii) of this section, a leak is
detected.
(ii) When a leak is
detected, it shall be repaired as soon as practicable, but not later than 15
calendar days after it is detected, except as provided in 264.1059.
(iii) A first attempt at repair (e.g.,
relapping the seal) shall be made no later than 5 calendar days after each leak
is detected.
(e) Any pump that is designated, as described
in 264.1064(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 paragraphs (a), (c) and (d) of this section 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 264.1063(c).
(3) Must be tested for compliance with
paragraph (e)(2) of this section initially upon designation, annually, and at
other times as requested by the Department.
(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
264.1060, it is exempt from the requirements of paragraphs (a) through (e) of
this section.
