(a) The owner or operator of waste pile units
				  subject to section
				  66265.254 shall submit a proposed
				  action leakage rate to the Department when submitting the notice required under
				  section 66265.254. The Department will
				  establish an action leakage rate, either as proposed by the owner or operator
				  or modified using the criteria in this section.
(b) The Department shall approve an action
				  leakage rate for waste pile units subject to section
				  66265.254. The action leakage rate
				  is the maximum design flow rate that the leak detection system (LDS) can remove
				  without the fluid pressure head on the bottom liner exceeding 1 foot (30.5 cm)
				  at any govern portion of the liner. The action leakage rate shall include an
				  adequate safety margin to allow for uncertainties in the design (e.g., slope,
				  construction, operation, and location of the LDS, waste and leachate
				  characteristics, likelihood and amounts of other sources of liquids in the LDS,
				  and proposed response actions (e.g., the action leakage rate shall consider
				  decreases in the flow capacity of the system over time resulting from siltation
				  and clogging, rib layover and creep of synthetic components of the system,
				  overburden pressures, etc.).
(c) To
				  determine if the action leakage rate has been exceeded, the owner or operator
				  shall convert the weekly flow rate from the monitoring data obtained under
				  section 66265.260, to an average daily
				  flow rate (gallons per acre per day) for each sump. Unless the Department
				  approves a different calculation, the average daily flow rate for each sump
				  shall be calculated weekly during the active life and closure period.
