Dick Wolfe July 1, 2009 D 7 i age Z. required that RMCC obtain a well permit for the pit. A well permit was requested and assigned a receipt number of 3600747. The State requested that we obtain waivers from well owners within 600 feet of the pit. In March 2008, we sent letters and waiver forms to the four well owners within 600 feet, requesting that they waive any objection to the issuance of a well permit for the Bromley Lakes Pit. The City of Brighton was the only well owner that returned a signed waiver (attached). We never received a response from the other three well owners. We understand that the State may hold a hearing in order for a permit to be issued without the waivers. This renewal request is proposing generally the same operations as the previous request. RMCC switched their mining operations to Erger's Pit in August 2008 and will remain in Erger's for several years. RMCC stopped dewatering Cell 3 of the Bromley Lakes Pit in July 2008, causing the total exposed groundwater within the pit to reach a maximum of 44 acres. Cell 2 continues to be used as the water supply for dust suppression water use. These and the evaporative depletions off of the exposed groundwater will be replaced by Fulton shares, water stored in Kenneth Mitchell Lake, and a lease with the City of Brighton. DEPLETIONS The projected depletions at the pit for the period of this SWSP (August 2009 through July 2010) are given in Table lA and consist of 117.3 acre-feet of net evaporation from the exposed water surface (Column [6]) and 2.0 acre-feet of water used for dust control (Column [7]). These depletions total 119.3 acre-feet of consumptive use at the site for the period of the SWSP (Column [8]). The lagging of these depletions and out-of-priority depletions which occurred during previous SWSPs total 111.9 acre-feet (Table 1B, Column [91). The lagging methodology was explained in the December 18, 2006 SWSP request. REPLACEMENT SOURCES Fulton Ditch Shares RMCC owns a total of 70 Fulton Ditch shares. RMCC proposes to replace the depletions from the Bromley Lakes site with 25 of these shares in the Fulton Ditch. The remaining 45 Fulton Ditch shares will be used to replace depletions caused by the North Tower Pit and Ready Mixed Pit 1. All of the Fulton Ditch shares will be jointly operated. If, at any time, there are extra Fulton credits at one pit and remaining depletions at another pit, the extra credits will be used to replace depletions. All the shares will be delivered down the lateral that historically served the Bromley Lakes Site and will be measured prior to their storage in Kenneth Mitchell Lake and/or their release to the river for replacement of depletions. RMCC has an agreement with the City of Brighton to allow for up to 200 acre-feet of RMCC storage in Kenneth Mitchell Lake. As in the previous SWSP an annual consumptive use credit of 1.76 acre-feet per share is claimed, yielding 44.0 acre-feet of replacement water per year for 25 shares. The distribution of the 25 shares is
