Sec. 264.1052  Standards: Pumps in light liquid service.

    (a)(1) Each pump in light liquid service shall be monitored monthly 
to detect leaks by the methods specified in Sec. 264.1063(b), except as 
provided in paragraphs (d), (e), and (f) of this section.
    (2) Each pump in light liquid service shall be checked by visual 
inspection each calendar week for indications of liquids dripping from 
the pump seal.
    (b)(1) If an instrument reading of 10,000 ppm or greater is 
measured, a leak is detected.
    (2) If there are indications of liquids dripping from the pump seal, 
a leak is detected.
    (c)(1) When a leak is detected, it shall be repaired as soon as 
practicable, but not later than 15 calendar days after it is detected, 
except as provided in Sec. 264.1059.
    (2) A first attempt at repair (e.g., tightening the packing gland) 
shall be made no later than 5 calendar days after each leak is detected.
    (d) Each pump equipped with a dual mechanical seal system that 
includes a barrier fluid system is exempt from the requirements of 
paragraph (a) of this section, provided the following requirements are 
met:
    (1) Each dual mechanical seal system must be:
    (i) Operated with the barrier fluid at a pressure that is at all 
times greater than the pump stuffing box pressure, or
    (ii) Equipped with a barrier fluid degassing reservoir that is 
connected by a closed-vent system to a control device that complies with 
the requirements of Sec. 264.1060, or
    (iii) Equipped with a system that purges the barrier fluid into a 
hazardous waste stream with no detectable emissions to the atmosphere.
    (2) The barrier fluid system must not be a hazardous waste with 
organic concentrations 10 percent or greater by weight.
    (3) Each barrier fluid system must be equipped with a sensor that 
will detect failure of the seal system, the barrier fluid system, or 
both.
    (4) Each pump must be checked by visual inspection, each calendar 
week, for indications of liquids dripping from the pump seals.
    (5)(i) Each sensor as described in paragraph (d)(3) of this section 
must be checked daily or be equipped with an audible alarm that must be 
checked monthly to ensure that it is functioning properly.
    (ii) The owner or operator must determine, based on design 
considerations and operating experience, a criterion that indicates 
failure of the seal system, the barrier fluid system, or both.
    (6)(i) If there are indications of liquids dripping from the pump 
seal or the

sensor indicates failure of the seal system, the barrier fluid system, 
or both based on the criterion determined in paragraph (d)(5)(ii) of 
this section, a leak is detected.
    (ii) When a leak is detected, it shall be repaired as soon as 
practicable, but not later than 15 calendar days after it is detected, 
except as provided in Sec. 264.1059.
    (iii) A first attempt at repair (e.g., relapping the seal) shall be 
made no later than 5 calendar days after each leak is detected.
    (e) Any pump that is designated, as described in Sec. 
264.1064(g)(2), for no detectable emissions, as indicated by an 
instrument reading of less than 500 ppm above background, is exempt from 
the requirements of paragraphs (a), (c), and (d) of this section if the 
pump meets the following requirements:
    (1) Must have no externally actuated shaft penetrating the pump 
housing.
    (2) Must operate with no detectable emissions as indicated by an 
instrument reading of less than 500 ppm above background as measured by 
the methods specified in Sec. 264.1063(c).
    (3) Must be tested for compliance with paragraph (e)(2) of this 
section initially upon designation, annually, and at other times as 
requested by the Regional Administrator.
    (f) If any pump 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 Sec. 264.1060, it 
is exempt from the requirements of paragraphs (a) through (e) of this 
section.
