By 30 May 2013, the Discharger shall submit a Potential Conduit Well Abandonment/Destruction Workplan that addresses the discussion in Finding 52. The Workplan shall describe how Wells X, PW-2, and PW -3 (if applicable, see discussion below) will be properly abandoned/destroyed to prevent shallow groundwater from migrating to lower groundwater zones. i. If the Discharger proposes to investigate and abandon Well PW-3, rather than destroy the well, then the following items shall be included in the workplan: 1) Relative groundwater elevations between the first saturated interval and lower saturated intervals. 2) Production geophysical well logs to determine borehole conditions. Logs may include fluid resistivity, video, flow meter, and depth specific sampling. If appropriate, the relative groundwater elevations and geophysical logs shall be recorded during both operational and non-operational periods. ii. If the Discharger proposes to abandon Well PW-3, proposed abandonment procedures, if any. Well abandonment shall effectively seal the upper groundwater zones from lower zones. Interpretation of the geophysical logs may be necessary to determine the extent of work required. i. By 30 November 2013, the Discharger shall submit a Potential Conduit Well Destruction Report that describes the destruction of Wells X, PW -2, and PW -3 (if applicable). j. By 30 September 2016, the Discharger shall submit a Pond Liner Integrity Evaluation Workplan that specifies the means and methods that the Discharger proposes to use to evaluate all geosynthetic liner and leak detection systems. 2. If the Discharger proposes to abandon any monitoring wells, the Discharger shall submit a Well Abandonment Workplan with a request to revise the Monitoring and Reporting Program. The Workplan shall include a specific description of the wells to be abandoned and justification for removing them from the compliance monitoring network; and a detailed description of the proposed abandonment procedures. The Discharger shall continue to comply with the Monitoring and Reporting Program unless and until the Executive Officer approves well abandonment and issues a revised Monitoring and Reporting Program. 3.
