Varra Companies, Inc. <br />Office of Special Projects <br />8120 Gage Street Frederick Colorado 80516 Telephone (970) 353-8310 Fax(970)353-4047 <br />c) The Applicant will provide the Division with a groundwater monitoring <br />plan which will be implemented by the operator to verify the presence or <br />absence of impacts to the groundwater system in the affected land and the <br />surrounding area through the life of the operation. At a minimum, the <br />groundwater monitoring plan should include the location of monitoring stations, <br />frequency of water table elevations to be collected, commitments for baseline <br />data collection prior to exposure of groundwater, commitments for reporting <br />measurements to the Division, water level criteria that will be used to determine <br />when an adverse affect to groundwater has occurred, and commitments for <br />mitigation in the event the adverse impact criteria are exceeded. If this option is <br />chosen, the division recommends that at least 5 quarters of baseline water level <br />data be collected prior to exposure of groundwater at the site. <br />Please refer to the included report from C.G.R.S. <br />23. The Applicant has stated stormwater will be retained internally by <br />vegetated berms. Please clarify if the berms are existing or will be constructed. <br />If they are to be constructed, please provide the Division with the location and <br />approximate dimensions of the berms. <br />A small diversion ditch, approximately 0.5± feet deep with the overcast forming <br />an additional 0.5± feet in height; or a total of 1.0± feet, will be located along the <br />west boundary of the location as a means of protecting the attending slope <br />below the berm from eroding during short duration, high intensity thunderstorm <br />events (10± year events). The design is empirically derived as included and <br />shown in the attending stormwater management plan and map, as provided with <br />this correspondence. <br />24. The Applicant submitted comments from CGRS dated July 1, 2010. The <br />comments address the impacts of impermeable barriers on groundwater <br />Varra Companies, Inc. correspondence to the Colorado Office of Mined Land Reclamation (OMLR) 13 <br />in reply. to OMLR correspondence of 4 October 2010 - Western Sugar Reclamation Land Development Project <br />- M-2010-049.
