As such, the clay liner is simply an option that will benefit <br />the owner by liberating waters set aside for augmentation once the lined pond is <br />certified. The leak test is underway and is anticipated to be finalized near <br />year's end. Results of the leak test and legal standing with the State Engineer <br />will be provided to OMLR as a stipulation to the approved technical revision. <br />Item #3 Bond Estimate: <br />Based on your response to the items above, the Division will conduct a financial <br />warranty estimate for the current level of disturbance and adjust the required <br />warranty accordingly. <br />Acknowledged. <br />Item #4 Hydrologic Balance: <br />Given the proximity of the northwest clay lined pond to the structures located of <br />the pond, the Division believes monitoring the groundwater elevations in that <br />vicinity is warranted. Should a mounding problem arise, monitoring data will be <br />necessary to determine the cause. One piezometer will need to be installed <br />south of the northwest clay lined pond between the pond and the permit <br />boundary. The Operator will need to commit to installing this piezometer and <br />monitoring the groundwater elevations on a quarterly basis until the site is <br />released by the Division. Please commit to supplying the results of the <br />groundwater monitoring data in the annual reclamation report submitted to the <br />Division. On the updated Reclamation Plan map, please indicate where the <br />piezometers will be installed. <br />Please refer to the included map shoving piezometers locations as determined <br />by C.G.R.S. Please note that the locations are approximate and will be field fit <br />so as not to interfere with existing obstructions, rights-of-way, easements or <br />related considerations. All other aspects of the OMLR request in Item I will be <br />complied with. <br />Varra Companies, Inc. correspondence to the Colorado Office of Mined Land Reclamation (Office) in reply to 3 <br />Office correspondence of 29 July 2010 - Dakolios Pit - M-1984-036.
