AWES, ��C <br />. Fort Collins, Colorado, USA <br />December 10, 2013 <br />Varra Companies <br />8120 Gage Street <br />Frederick, Colorado 80516 <br />Attn: Mr. Garrett Varra <br />RE: Well Inspection Record <br />RECEIVED <br />Lightsey Domestic Well <br />Weld County, Colorado <br />AWES No. 1 -1 -108 <br />JAN 2 2 2014 <br />Division of Reclamation, <br />Dear Mr. Varra: <br />Mining & Safety <br />At the request of Varra Companies, Inc. ( Varra) I inspected the domestic well currently owned by <br />Mr. Paul A. Lightsey of Greeley, Colorado. The purpose of the inspection was to document the <br />construction details of the well and respond to concerns presented in a letter dated October 27, <br />2013, addressed to Mr. Garrett Varra of Varra Companies, Inc. Mr. Lightsey's letter is presented in <br />Attachment A. The well is located approximately 300 feet south of the southern extent of the Varra <br />Coulson gravel quarry mine (DRMS Permit # M- 2013 -064). The well inspection was conducted on <br />November 26, 2013. Personnel present during the inspection were Mr. Brad Janes, me and Mr. <br />Paul Lightsey. The site location is depicted on Figure 1. The location of the well with respect to <br />Varra mining operations is also depicted on Figure 1. <br />The concern presented by Mr. Lightsey was that the predicted drawdown in the vicinity of his well <br />(based on numerical analyses) would diminish or eliminate the ability of the well and pump to <br />provide irrigation water. Based on my inspection it is my opinion that dewatering associated <br />with the Varra Coulson mine has the potential to reduce or eliminate the ability of the pump, in its <br />current configuration, to generate the required suction lift. If the well is retrofitted with a <br />submersible pump the well has sufficient water column to supply the needs for light irrigation <br />use. The rational for this opinion is provided below. <br />The construction details of the well of interest are as follows: <br />1. Four -inch diameter, steel casing (assumed) with expanding well seal; <br />2. Top of well casing approximately 4.5 feet below grade located within a circular <br />concrete vault; <br />3. Depth to water measured at 7.5 feet below top of casing (TOC); <br />�W�S 4809 Four Star Court, Fort Collins, CO 80524 970 -590 -3807 <br />
