Ill. Admin. Code tit. 35, § 721.959 - Standards: Delay of Repair
a)
Delay of repair of equipment for which leaks have been detected will be allowed
if the repair is technically infeasible without a hazardous secondary material
management unit shutdown. In such a case, repair of this equipment must occur
before the end of the next hazardous secondary material management unit
shutdown.
b) Delay of repair of
equipment for which leaks have been detected will be allowed for equipment that
is isolated from the hazardous secondary material management unit and that does
not continue to contain or contact hazardous secondary material with organic
concentrations at least 10 percent by weight.
c) Delay of repair for valves will be allowed
if:
1) The remanufacturer or other person
that stores or treats the hazardous secondary material determines that
emissions of purged material resulting from immediate repair are greater than
the emissions likely to result from delay of repair.
2) When repair procedures are effected, the
purged material is collected and destroyed or recovered in a control device
complying with Section 721.960.
d) Delay of repair for pumps will be allowed
if both of the following conditions are fulfilled:
1) Repair requires the use of a dual
mechanical seal system that includes a barrier fluid system; and
2) Repair is completed as soon as
practicable, but not later than six months after the leak was
detected.
e) Delay of
repair beyond a hazardous secondary material management unit shutdown will be
allowed for a valve if valve assembly replacement is necessary during the
hazardous secondary material management unit shutdown, valve assembly supplies
have been depleted, and valve assembly supplies had been sufficiently stocked
before the supplies were depleted. Delay of repair beyond the next hazardous
secondary material management unit shutdown will not be allowed unless the next
hazardous secondary material management unit shutdown occurs sooner than six
months after the first hazardous secondary material management unit
shutdown.
