   Subpart V_National Emission Standard for Equipment Leaks (Fugitive 
                            Emission Sources)
 
Sec. 61.242-10  Standards: Delay of repair.

    (a) Delay of repair of equipment for which leaks have been detected 
will be allowed if repair within 15 days is technically infeasible 
without a process unit shutdown. Repair of this equipment shall occur 
before the end of the next process unit shutdown.
    (b) Delay of repair of equipment for which leaks have been detected 
will be allowed for equipment that is isolated from the process and that 
does not remain in VHAP service.
    (c) Delay of repair for valves will be allowed if:
    (1) The owner or operator demonstrates that emissions of purged 
material resulting from immediate repair are greater than the fugitive 
emissions likely to result from delay of repair, and
    (2) When repair procedures are effected, the purged material is 
collected and destroyed or recovered in a control device complying with 
Sec. 61.242-11.
    (d) Delay of repair for pumps will be allowed if:
    (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 6 
months after the leak was detected.
    (e) Delay of repair beyond a process unit shutdown will be allowed 
for a valve if valve assembly replacement is necessary during the 
process 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 process unit 
shutdown will not be allowed unless the next process unit shutdown 
occurs sooner than 6 months after the first process unit shutdown.
