' mining boundary. An additions{ 6 wells are permitted, but no[ located according [o SEO
records.
The Cacfte La Poudre River should serve as a ground water divide and therefore, no alluvial
ground water declines are expected south of the river from any dewatering activities at the
' site.
' 3.04 Water Requirements
Ground water will be consumed at the mining operation by evaporation of exposed ground
' water and water in the extracted produc[. The annual evaporation is approximately 2.3 feet
per acre. For the In-Place Mining Plan, phases 1. 2, and 3 will expose approximately a total
' of X1.4 acres. Ivtining of Phase =t will expose approximately an additional 8.0 acres. At a

For the Relocation Ivlining Plan, approximately 3.6 acres of ground water will be exposed
annually. First year evaporation will be approximately 8.3 acre-feet and annual depletion a[
the conclusion of mining will be approximately 114.8 acre-feet.
Depletion of the ground water will also occur from water in the product. The amount of
water removed from the site in the product is Four percent by weight. The estimated annual
depletion from removal of product is ~.9 acre-fee[. During [he las[ year of th [n-Place [vlining
Plan, the maximum annual rate oFdepletion is 12L7 acre-feet, for the Relocation Plan, the
maximum annual rate is 120.7 acre-feet.
8.05 Project Water Supply
Prior to exposing the ground water the applicant will be required by the State Engineer's ~'
Office to obtain a well permit and Substitute ~~':uer Supply Plan. The .Applicant does not own
senior a:ttzr ri~_hts in the Oeilvv Ditch.
