Haw. Code R. § 11-265-1057 - Standards: Valves in gas/vapor service or in light liquid service
(a) Each valve in gas/vapor or light liquid
service shall be monitored monthly to detect leaks by the methods specified in
subsection 11-265-1063(b) and shall comply with subsections (b) through (e),
except as provided in subsections (f), (g), and (h) and sections 11-265-1061 and 11-265-1062.
(b) If an
instrument reading of ten-thousand ppm or greater is measured, a leak is
detected.
(c)
(1) Any valve for which a leak is not
detected for two successive months may be monitored the first month of every
succeeding quarter, beginning with the next quarter, until a leak is
detected.
(2) If a leak is
detected, the valve shall be monitored monthly until a leak is not detected for
two successive months.
(d)
(1)
When a leak is detected, it shall be repaired as soon as practicable, but no
later than fifteen calendar days after the leak is detected, except as provided
in section 11-265-1059.
(2) A first
attempt at repair shall be made no later than five calendar days after each
leak is detected.
(e)
First attempts at repair include, but are not limited to, the following best
practices where practicable:
(1) Tightening
of bonnet bolts.
(2) Replacement of
bonnet bolts.
(3) Tightening of
packing gland nuts.
(4) Injection
of lubricant into lubricated packing.
(f) Any valve that is designated, as
described in paragraph 11-265-1064(g)(2), for no detectable emissions, as
indicated by an instrument reading of less than five-hundred ppm above
background, is exempt from the requirements of subsection (a) if the valve:
(1) Has no external actuating mechanism in
contact with the hazardous waste stream.
(2) Is operated with emissions less than
five-hundred ppm above background as determined by the method specified in
subsection 11-265-1063(c).
(3) Is
tested for compliance with paragraph (f)(2) initially upon designation,
annually, and at other times as requested by the director.
(g) Any valve that is designated, as
described in paragraph 11-265-1064(h)(1), as an unsafe-to-monitor valve is
exempt from the requirements of subsection (a) if:
(1) The owner or operator of the valve
determines that the valve is unsafe to monitor because monitoring personnel
would be exposed to an immediate danger as a consequence of complying with
subsection (a).
(2) The owner or
operator of the valve adheres to a written plan that requires monitoring of the
valve as frequently as practicable during safe-to-monitor times.
(h) Any valve that is designated,
as described in paragraph 11-265-1064(h)(2), as a difficult-to-monitor valve is
exempt from the requirements of subsection (a) if:
(1) The owner or operator of the valve
determines that the valve cannot be monitored without elevating the monitoring
personnel more than two meters above a support surface.
(2) The hazardous waste management unit
within which the valve is located was in operation before June 21,
1990.
(3) The owner or operator of
the valve follows a written plan that requires monitoring of the valve at least
once per calendar year.
