La. Admin. Code tit. 33 § V-1719

Current through Register Vol. 50, No. 11, November 20, 2024

Section V-1719 - Standards: Pumps in Light Liquid Service

A. Monitoring

1. Each pump in light liquid service shall be monitored monthly to detect leaks by the methods specified in LAC 33:V.1741.B, except as provided in Subsections 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. Leak Detection

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. Repair

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 LAC 33:V.1733.

2. A first attempt at repair (e.g., tightening the packing gland) shall be made no later than five calendar days after each leak is detected.

D. Dual Mechanical Seal Exemption. Each pump equipped with a dual mechanical seal system that includes a barrier fluid system is exempt from the requirements of LAC 33:V.1719.A provided the following requirements are met.

1. Operation and Equipment. Each dual mechanical seal system must be:

a. operated with the barrier fluid at a pressure that is at all times greater than the pump stuffing box pressure; or

b. 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 LAC 33:V.1735; or

c. equipped with a system that purges the barrier fluid into a hazardous waste stream with no detectable emissions to the atmosphere.

2. Barrier Fluid System. The barrier fluid system must not be a hazardous waste with organic concentrations 10 percent or greater by weight.

3. Barrier Fluid System Sensor. 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. Pump Inspection. Each pump must be checked by visual inspection, each calendar week, for indications of liquids dripping from the pump seals.

5. Seal System and Sensor Function

a. Each sensor as described in LAC 33:V.1719.D.3 must be checked daily or be equipped with an audible alarm that must be checked monthly to ensure that it is functioning properly.

b. The owner or operator must determine, on the basis of design considerations and operating experience, a criterion that indicates failure of the seal system, the barrier fluid system, or both.

6. Leak Detection and Repair

a. 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 on the basis of the criterion determined in LAC 33:V.1719.D.5.b, a leak is detected.

b. 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 LAC 33:V.1733.

c. A first attempt at repair (e.g., relapping the seal) shall be made no later than five calendar days after each leak is detected.

E. No Detectable Emission Exemption. Any pump that is designated, as described in LAC 33:V.1743.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 LAC 33:V.1719.A, C, and D if the pump meets the following requirements.

1. The pump must have no externally actuated shaft penetrating the pump housing.

2. The pump 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 LAC 33:V.1741.C.

3. The pump must be tested for compliance with LAC 33:V.1719.E.2 initially upon designation, annually, and at other times as requested by the administrative authority.

F. Closed Vent System Exemption. 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 LAC 33:V.1735, it is exempt from the requirements of LAC 33:V.1719.A-E.
