Current through Register Vol. 50, No. 9, September 20, 2024
A. The
facility must provide the department with 30 days advanced notice of the times
of installation to allow the administrative authority the opportunity to
inspect the liner and installation.
B. During construction or installation,
liners (except in the case of existing portions of landfills exempt from LAC
33:V.2503.A) and cover systems (e.g., membranes, sheets, or coatings) must be
inspected for uniformity, damage, and imperfections (e.g., holes, cracks, thin
spots, or foreign materials). Immediately after construction or installation:
1. synthetic liners and covers must be
inspected to ensure tight seams and joints and the absence of tears, punctures,
or blisters; and
2. soil-based and
admixed liners and covers must be inspected for imperfections including lenses,
cracks, channels, root holes, or other structural non-uniformities that may
cause an increase in the permeability of the liner or cover.
C. While a landfill is in
operation, it must be inspected weekly and after storms to detect evidence of
any of the following:
COMMENT: The permit application must include a detailed
inspection plan.
1. deterioration,
malfunctions, or improper operation of run-on and run-off control
systems;
2. the presence of liquids
in leak detection systems;
3.
proper functioning of wind dispersal control systems, where present;
and
4. the presence of leachate in
and proper functioning of leachate collection and removal systems, where
present.
D. An owner or
operator required to have a leak detection system under LAC 33:V.2503.L or M
must record the amount of liquids removed from each leak detection system sump
at least once each week during the active life and closure period.
1. After the final cover is installed, the
amount of liquids removed from each leak detection system sump must be recorded
at least monthly. If the liquid level in the sump stays below the pump
operating level for two consecutive months, the amount of liquids in the sumps
must be recorded at least quarterly. If the liquid level in the sump stays
below the pump operating level for two consecutive quarters, the amount of
liquids in the sumps must be recorded at least semi-annually. If, at any time
during the post-closure care period, the pump operating level is exceeded at
units on quarterly or semi-annual recording schedules, the owner or operator
must return to monthly recording of amounts of liquids removed from each sump
until the liquid level again stays below the pump operating level for two
consecutive months.
2.
Pump
Operating Level-a liquid level proposed by the owner or operator and
approved by the administrative authority based on pump activation level, sump
dimensions, and level that avoids backup into the drainage layer and minimizes
head in the sump.
