Mr. Andy Rodriguez, P.E Shores SWSP Page 3 of 5 impermeable boundary to the creek (W) = 10,000 feet. The attached Table 4 provides a monthly schedule of lagged depletions to the river system due to operational losses, shown to be 56.73 acre -feet for this plan period. Including depletions due to past dewatering activities, the total lagged depletion to the river system in this plan period is 74.56 acre -feet, as shown on Table 4. Replacements The sources of replacement water is established through a water lease agreement between Central Colorado Water Conservancy District and Bestway Concrete & Aggregates. The replacement water will be measured and delivered from the Shores facility adjacent to the subject site. Specifically, the water is measured as it moves through Centrals pump system and reported as a release from Shores Lakes (0503900) with the water returning to the river via the Rural Ditch Augmentation Return (0502303). A monthly breakdown of depletions and replacement is shown on the attached Table 5. Conditions of Approval I approve the proposed substitute water supply plan in accordance with Section 37 -90- 137(11), C.R.S., subject to the following conditions: 1. This SWSP shall be valid for the period of November 1, 2013 through December 31, 2014, unless otherwise revoked, modified, or superseded by decree.

The total surface area of the groundwater exposed at the Shores Pit must not exceed 11 acres during the approval period of this SWSP resulting in an annual evaporative loss of 30.66 acre -feet. 4. The amount of water used at the operation shall not exceed 1.93 acre -feet for dust control, and the amount used for concrete batching shall not exceed 1.64 acre -feet used in the production of 118,589 cubic yards of concrete. 5. Total consumption at the Shores Pit must not exceed the aforementioned amounts unless an amendment is made to this plan. 6. Approval of this plan is for the purposes as stated herein.
