Applegate Group, Inc. Water Resource Advisors for the West July 20, 2015 Mr. Berhan Keffelew Division of Reclamation, Mining and Safety 1313 Sherman Street, RM 215 Denver, CO 80203 RE: Brannan Sand & Gravel Company Pit 29, Permit No. M-1980-183, Water Level Monitoring Dear Mr. Keffelew: Pursuant to Revision TR -3 we are submitting the monitor well measurements for the quarter ending June 30, 2015. There were three monitor wells on the site; MW -1 (east), MW -2 (south) and MW -4 (west). The well MW -3 has been abandoned, and MW -4 has been added as a replacement. Attached is the report showing the well measurements taken on July 17, 2015, and a figure showing the location of the monitoring wells. We would also like to note that we have, as of February 4, 2013, placed a pressure transducer in the reservoir on the east side of the property. (An additional pressure transducer was placed in the monitoring well (MW -4) on January 3, 2013.) These transducers will take readings once every hour, and we will be able to access these readings when we visit the site periodically. We have had the appropriate locations of the transducers surveyed for a correct elevation reading, and have compared the elevation of the water table underneath MW -4 to the water surface elevation at the reservoir. A plot of our hourly measurements is also included. If you have any questions please call me at your convenience.
