3745-68-04 Monitoring and inspection.

(A) An owner or operator required to have a leak detection system under paragraph (A) of rule 3745-68-05 of the Administrative Code 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.

(B) 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.

(C) "Pump operating level" is a liquid level proposed by the owner or operator and approved by the director based on pump activation level, sump dimensions, and level that avoids backup into the drainage layer and minimizes head in the sump. The timing for submittal and approval of the proposed "pump operating level" will be in accordance with paragraph (A) of rule 3745-68-02 of the Administrative Code.
