Section 66265.226 - Monitoring and Inspection(a) The owner or operator shall inspect:(1) the freeboard level at least once each operating day to ensure compliance with section 66265.222, and(2) the surface impoundment, including dikes and vegetation surrounding the dike, at least once a week to detect any leaks, deterioration, or failures in the impoundment.(b)(1) An owner or operator required to have a leak detection system under section 66265.221(a) 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 drainage layer and minimizes head in the sump. The timing for submission and approval of the proposed "pump operating level" will be in accordance with section 66265.222(a).Cal. Code Regs. Tit. 22, § 66265.226
