                    Subpart F - Equipment Leaks
 
Sec. 65.110  Standards: Pumps, valves, connectors, and agitators in heavy liquid service; pressure relief devices in liquid service; and instrumentation 
          systems.

    (a) Compliance schedule. The owner or operator shall comply with 
this section no later than the implementation date specified in 
Sec. 65.1(f).
    (b) Leak detection. Unless otherwise specified in Sec. 
65.102(b), the owner or operator shall comply with the following:
    (1) Monitoring method. Pumps, valves, connectors, and agitators in 
heavy liquid service; pressure relief devices in light liquid or heavy 
liquid service; and instrumentation systems shall be monitored within 5 
calendar days by the method specified in Sec. 65.104(b) and 
(c) if evidence of a potential leak to the atmosphere is found by 
visual, audible, olfactory, or any other detection method, unless the 
potential leak is repaired as required in paragraph (c) of this section.
    (2) Instrument reading that defines a leak. If an instrument reading 
of 10,000 parts per million or greater for agitators, 5,000 parts per 
million or greater for pumps handling polymerizing monomers, 2,000 parts 
per million or greater for all other pumps (including pumps in food/
medical service), or 500 parts per million or greater for valves, 
connectors, instrumentation systems, and pressure relief devices is 
measured pursuant to paragraph (b)(1) of this section, a leak is 
detected and it shall be repaired pursuant to Sec. 65.105, as 
applicable.
    (c) Leak repair. For equipment identified in paragraph (b) of this 
section that is not monitored by the method specified in Sec. 
65.104(b), repaired shall mean that the visual, audible, olfactory, or 
other indications of a leak to the atmosphere have been eliminated; that 
no bubbles are observed at potential leak sites during a leak check 
using soap solution; or that the system will hold a test pressure.
