Universal Citation: 35 IL Admin Code ยง 724.403
Current through Register Vol. 48, No. 38, September 20, 2024
a) During construction or installation, liners (except in the case of existing portions of landfills exempt from Section 724.401(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 the following must occur:
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.
b) While a landfill is in operation, it must be inspected weekly and after storms to detect evidence of any of the following:
1) Deterioration, malfunctions, or
improper operation of run-on and run-off control systems;
2) Proper functioning of wind dispersal
control systems, where present; and
3) The presence of leachate in and proper
functioning of leachate collection and removal systems, where
present.
c) Monitoring of LDS.
1) An owner or operator required to
have a LDS under Section
724.401(c) or
(d) must record the amount of liquids removed
from each LDS sump at least once each week during the active life and closure
period.
2) After the final cover is
installed, the amount of liquids removed from each LDS 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.
3) "Pump operating level"
is a liquid level proposed by the owner or operator pursuant to 35 Ill. Adm.
Code
703.207(b)(1)(E)
and approved by the Agency based on pump
activation level, sump dimensions, and level that avoids backup into the
drainage layer and minimizes head in the sump.
