326 IAC 14-9-5 - Equipment leaks
Authority: IC 13-14; IC 13-17-3
Affected: IC 13-14; IC 13-17
Sec. 5.
(a) Each
owner or operator of equipment in benzene service shall comply with the
requirements of
326 IAC 14-8 and 40 CFR 61,
Subpart V*, except as provided in this section.
(b) The provisions of
40 CFR
61.242-3 * and 61.242-9*, do not apply to
this rule.
(c) Each piece of
equipment in benzene service to which this rule applies shall be marked in such
a manner that it can be distinguished readily from other pieces of
equipment.
(d) Each exhauster shall
be monitored quarterly to detect leaks by the methods specified in
326 IAC 14-8-3(a)
and
40 CFR
61.245(b) *, except as
provided in subsections (e), (f), and (g) and section 6(c) of this rule.
(1) If an instrument reading of ten thousand
(10,000) ppm or greater is measured, a leak is detected.
(2) When a leak is detected, it shall be
repaired as soon as practicable, but no later than fifteen (15) calendar days
after it is detected, except as provided in
40 CFR
61.242-10(a) * and
40 CFR
61.242-10(b) *. A first
attempt at repair shall be made no later than five (5) calendar days after each
leak is detected.
(e)
Each exhauster equipped with a seal system that includes a barrier fluid system
and that prevents leakage of process fluids to the atmosphere is exempt from
the requirements of subsection (d) provided the following requirements are met:
(1) Each exhauster seal system is:
(A) operated with the barrier fluid at a
pressure that is greater than the exhauster stuffing box pressure; or
(B) equipped with a barrier fluid system that
is connected by a closed vent system to a control device that complies with the
requirements of 40 CFR
61.242-11 *; or
(C) equipped with a system that purges the
barrier fluid into a process stream with zero (0) benzene emissions to the
atmosphere.
(2) The
barrier fluid is not in benzene service.
(3) Each barrier fluid system shall be
equipped with a sensor that will detect failure of the seal system, barrier
fluid system, or both.
(4) Each
sensor as described in subsection (e)(3) shall be checked daily or shall be
equipped with an audible alarm.
(5)
The owner or operator shall determine, based on design consideration and
operating experience, a criterion that indicates failure of the seal system,
the barrier fluid system, or both.
(6) If the sensor indicates failure of the
seal system, the barrier system, or both, based on the criterion determined
under subdivision (5), a leak is detected.
(7) 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
40 CFR
61.242-10 *.
(8) A first attempt at repair shall be made
no later than five (5) calendar days after each leak is detected.
(f) An exhauster is exempt from
the requirements of subsection (d) if it 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
40 CFR
61.242-11 * except as provided in subsection
(g).
(g) Any exhauster that is
designated, as described in
326 IAC 14-8-4(d)
through
326 IAC 14-8-4(g)
and in
40 CFR
61.246(e) * 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
subsection (d) if the exhauster:
(1) is
demonstrated 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 methods specified in
326 IAC 14-8-3(b)
and in
40 CFR
61.245(c) *; and
(2) is tested for compliance with subdivision
(1) initially upon designation, annually, and at other times requested by the
commissioner.
(h) Any
exhauster that is in vacuum service is excluded from the requirements of this
rule if it is identified as required in
326 IAC 14-8-4(d)
and in
40 CFR
61.246(e)(5) *.
