11.3 The licensee shall implement a monitoring program of the leak detection systems for
Impoundments 4A and 4B in accordance with requirements of the Permit. The licensee shall also implement an operation, maintenance, and monitoring program of the leak detection systems for Impoundments 1, 2, and 3 as follows:
A. The licensee shall maintain all leak detection system piping, including any access
pipes, open, fully functional and free of soil, debris or detritus. All access pipes shall be capped to prevent inflow of rainwater, soil, debris, or detritus when not in use for monitoring or pumping. The licensee shall conduct annual video logs of said access pipes to demonstrate the physical condition of the system. In the event that the
licensee determines any access pipe is blocked, partially blocked, or otherwise not
fully functional, the licensee shall: 1) remove all blockages within 14 calendar days of discovery, and 2) submit a written report for Director approval within 30 calendar days of discovery.
B. Leak Detection System - The licensee shall measure and record the inches of water
pressure head on the pump transducer in each of the tailings disposal impoundment
leak detection system standpipes on a weekly basis in a manner approved by the Director. The transducer and pump will be placed as low as reasonably practical in the standpipe as approved by the Director. The system will be set such that the alarm will be triggered when the transducer senses a pressure of 2 inches of water head or greater,
and the pump will turn on when the transducer senses a water head pressure on the
transducer at or above the level for the impoundment specified in the following table:

Impoundment Water Head Pressure on Transducer
Impoundment 1 12 inches
Impoundment 2 18 inches
Impoundment 3 12 inches
C. If fluid is present in the leak detection system (LDS) of any impoundment above the
water head pressure on the transducer specified in the table set out in License Condition 11.3B, the licensee shall:
1. Pump the fluid from the LDS immediately upon discovery, to a water head pressure on the transducer at or below the level for the impoundment specified in
the table set out in License Condition 11.3B.
2. Immediately commence and continue daily monitoring of LDS water head pressure on the transducer, and volumes removed, until otherwise approved by the Director.
3. Maintain the water head pressure on the transducer at or below the level for the
impoundment specified in the table set out in License Condition 11.3(B).
4. Return any LDS fluid pumped to an approved disposal impoundment. D. If fluid is pumped from an LDS, the licensee shall calculate the flow rate either by a flow meter or by dividing the recorded volume of fluid recovered by the elapsed time
since fluid was last pumped or increases in the LDS fluid levels were recorded,
whichever is the more recent. The licensee shall document the results of this calculation. E. If the flow rate calculated under License Condition 11.3(D) is greater than zero for 30
continuous calendar days, but does not exceed one gallon per minute, the licensee
shall, unless it determines the root cause of the failure through other means, reduce the solution level in the Impoundment by up to 12 inches elevation to determine whether or not the reduction in solution elevation materially reduces the flow rate. If the flow rate is materially reduced, this will be considered to indicate that one or more liner
repairs are required above the reduced elevation level, where exposure to wave action
and the elements are most likely to have impacted the liner. If any such repairs are

required, the licensee will submit a plan and schedule for Director approval for an investigation of the liner above such reduced solution level and for completion of such
repairs.
If the licensee is unable to determine the root cause of the leak after following the steps described in this license condition, the licensee shall meet with the Director to determine whether or not any further actions are warranted and practicable in the
circumstances.
F. Either of the following events shall constitute a violation of this License: 1. Failure to maintain the LDS fluid level elevation pursuant to License Condition 11.3(C)(1), above, and such failure is not rectified within two days after discovery; or 2. the flow
rate calculated under License Condition 11.3(D) is equal to or greater than one gallon
per minute. Immediately upon determination of such an event, the licensee shall: (1) Evaluate the root cause of the event and take appropriate and timely actions to mitigate the event and any consequent potential impacts;
(2) Continue to measure and record LDS water head pressure on the transducer,
and removed volume measurements daily until otherwise approved by the Director; and (3) Notify the Director by telephone within 48 hours, in accordance with License Condition 9.2, and submit a written report, for Director approval, within 30
calendar days of said telephone notice, in accordance with License Condition
9.2. The written report shall include a description of the mitigative action(s) taken and a discussion of the mitigative action results. In the event that mitigative actions have yet to be taken, the written report will include a detailed workplan and schedule.

G. In addition to the reporting required in License Condition 11.3(A), (B), (C), and (D), all sampling, analysis, and evaluation of LDS fluids shall be documented and all records retained onsite until license termination for Director inspection.
