The operator commits to providing follow up as-built certification from a qualified, registered <br />professional engineer that the stabilization measures installed at the point of offsite discharge have <br />been constructed in accordance with the approved plans. <br />2. Please note that during our meeting on November 8, 2005 with Carl Mount, Bruce Humphries and <br />yourself, the Division agreed that the operator could expose groundwater in phase 1 priar to <br />collecting five quarters of baseline water quality data . However, the operator cannot expose <br />groundwater in any other phases prior to collection of this data. <br />3. The map showing the locations of the recharge pond and the schematic showing the height of water <br />level in the recharge pond in relation to the groundwater surface and Landrus well are attached to <br />the Groundwater Sampling and Analysis Plan (SAP). The schedule for when each recharge pond <br />will become operational is in Section 3.0 Proposed Project of the SAP. <br />4. The maximum infiltration rate from the recharge pond is 2,000 gallons per minute at each recharge <br />site. <br />5. The SAP includes a monitoring plan chat addresses baseline water quality monitoring for the <br />parameters you requested, a discussion of how the baseline concentration for each analyze will be <br />determined and exceedance verification measures. <br />6. Notification procedures to be followed in the event of an exceedance will be consistent with the <br />requirements of Rule 3.1.13. <br />7. A copy of the certified mail return receipts to the Landrus' is attached. <br />8. The operator will submit a revised plan for ongoing monitoring no later than 60 days prior to the end <br />of the initial two year monitoring. It is our understanding that the revised plan will require Division <br />review and approval via the technical revision process. <br />451 ^nK BTR EET, Su1TE 209 ~ P.O.
