April 22, 2014 John Paul Ary Fremont Paving and Ready Mix, Inc. 839 MacKenzie Avenue PO Box 841 Canon City, CO 81215 RE: M- 2000 -041 AM -01 Dear Mr. Ary, RECEIVED APR 23 2014 DIVISION OF RECLAMATION MINING AND SAFETY We have reviewed your letter dated January 13, 2014 and have the following comments: Although the letter mentions your commitment to monitoring, you have not defined any specific monitoring that will be performed. Your letter did not mention or provide your proposed methods to mitigate depletions created by the current mining operations in this area to our senior adjudicated wells. In addition, we did not identify any defined mitigation for these depletions through our search of the 112 permit on the DRMS website. The groundwater resource is critical to Southwest Farms, Inc. and mitigation of impacts and depletions to this resource from current and proposed future mining needs to be resolved. Southwest Farms, Inc. requests that you provide the following for review and concurrence by Southwest Farms, Inc. and that these issues be resolved before a modification to the mining permit is approved: • Details on the monitoring locations and on the methods that will be used to monitor groundwater conditions. • Details on the methods and locations for mitigation of current and future groundwater depletions. The methods and locations for monitoring and mitigation need to be included in the application for amendment (AM-01) to M- 2000 -041 Evans Pit #2. It is important that the monitoring and mitigation are clearly defined so that dewatering at the Evans Pit does not continue to cause adverse imparts to Southwest Farms, Inc. Also as requested I have assembled available data to illustrate the increasing impacts to the aquifer blow Southwest Farms, Inc. from expansion of mining operations and associated dewatering at the Evans Pit #2. However, the specific data that you requested is not available.
