Currentness
(a) During construction or installation, liners (except in the case of existing portions of landfills exempt from 66264.301(a)) and cover systems (e.g., membranes, sheets, or coatings) shall 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 shall 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 shall 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 shall 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;
(3) the presence of liquids in leak detection systems; and
(4) the presence of leachate in and proper functioning of collection and removal systems, where present.
(c)(1) An owner or operator required to have a leak detection system under section 66264.301(c) or (d) shall record the amount of liquids removed from each leak detection system 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 leak detection system sump shall 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 shall 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 shall 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 shall 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 and approved by the Department based on pump activation level, sump dimensions, and level that avoids backup into the drainage layer and minimizes head in the sump.
