The Division requested the Applicant submit a list of wells located within the <br />cone of depression, a report indicating potential impacts to these wells and a <br />groundwater monitoring plan to verify the presence or absence of impacts to <br />the groundwater system. At a minimum, the monitoring plan should include <br />the following: <br />a) The location of monitoring stations. <br />b) The frequency of water table elevation to be collected. <br />c) Commitments for reporting measurements to the Division. <br />d) Water level criteria that will be used to determine when an adverse affect to <br />groundwater has occurred. <br />e) Commitments for mitigation in the event the adverse impact criteria are <br />exceeded. <br />Please refer to the included Water Well Map, showing the well locations and <br />associated identity, summary List of wells shown. Even though impacts are <br />expected to be minimal, at the request of the OMLR, quarterly monitoring is <br />proposed with sampling to occur at the piezometer wells identified on the Water <br />Well Map (see legend). The results of all measurements will be included in the <br />required Annual Report to the OMLR. Parts d and e are addressed in <br />correspondence from C.G.R.S. of 14 April 2011, as included with this reply. <br />4. The Applicant has stated a Technical Revision may be submitted to allow for <br />the lining of the pits. As noted in the Division's previous Adequacy Review <br />Letter, the Division considers lined pits to be a developed water resource, <br />which would constitute a significant change from the proposed post-mining <br />land use of industrial/commercial and would require an Amendment rather <br />than a Technical Revision. The Division understands mine sites may be <br />reclaimed to multiple land uses. However, if the Applicant does not identify <br />`developed water resource' as one of the post-mining land uses, then the <br />Applicant will be required to amend the Reclamation Permit should they <br />decide to line the pits in the future. It is common practice to identify multiple <br />post-mining land uses on the permit application. The Applicant should be <br />familiar with this practice as they have identified multiple post-mining land <br />uses on previously submitted permit applications (copy enclosed). The <br />Applicant may revise page four of the permit application to include multiple <br />post-mining land uses. <br />Varra Companies, Inc. correspondence of 14 April 2011 to the Colorado Office of Mined Land Reclamation 6 <br />(OMLR) in reply to OMLR correspondence of 14 March 2011 - Western Sugar Reclamation Land <br />Development Project - M-2010-049.
