Current through Register Vol. 50, No. 9, September 20, 2024
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.
