City of Greeley August 13, 2013 Division of Reclamation, Mining and Safety Attn: Mr. Peter Hays 1313 Sherman Street, Room 215 Denver, Colorado 80203 REC V AOr, 74nn DIVISION OF ft§ blAf1g Y ININIA10A%) AFE�Fy Subject: Response to DRMS Inspection Report Dated August 1, 2013 25th Avenue Site, M- 2002 -020 Dear Mr. Hays: This letter is in response to the Division of Reclamation, Mining and Safety Inspection Report with signature date August 1, 2013. The City of Greeley appreciates the opportunity to provide DRMS with additional information concerning Greeley's past and ongoing contacts with members of the Rodman family, investigations, and implementation of mitigation steps concerning potential impacts to the Rodman water wells, located southeast of Greeley's 25th Avenue Site, from sand and gravel mining activities at the site. Greeley's Communications with the Rodmans As you may know, Greeley had communicated multiple times with the property owner, Mr. Bill Rodman, prior to DRMS receiving the July 3, 2012 message from his daughter, Ms. Prather. Previously, at Mr. Rodman's request shortly after the 25th Avenue Site dewatering began in August 2012, the City recorded well water levels in the two wells on the Rodman property (see Figure 1 prepared by Bill Schenderlein of Blue Earth Solutions, LLC, Greeley's project consultant). Mr. Rodman then contacted Mr. Schenderlein over concerns of water shortages in his wells on May 28, 2013. Mr. Rodman stated that, during extended periods of irrigation, his water supply was being interrupted because of low well water levels. On June 3, 2013, Mr. Schenderlein measured ground water levels in the two Rodman wells (Figure 1). Relative to the August 2012 water level measurements, Well #1 (Permit No. 3597 -F -R) and Well #2 (Permit No. 055880 -F) (see Figure 1) were 1.1 feet and 2.3 feet lower, respectively. While these relatively small fluctuations in well water levels could be caused by any number of influences (including annual or seasonal fluctuations, drought conditions, and/or aggregate mining and reclamation on other sites immediately west and north of the Rodman property —see attached Figure 2), Greeley took (and continues to take) prompt steps to investigate and implement potential remedies of any potential impacts that its mining activities might have on Mr. Rodman's wells.
