The required renewal fee of $257 has been received (receipt no. 3679492). The <br />Applicant shall be responsible for compliance with this SWSP, but the State Engineer’s Office may also <br />pursue the landowner for eventual compliance. <br />SWSP Operations <br />The Parsons Mine is located along the Cache La Poudre River in Sections 25 and 36, Township <br />6 North, Range 67 West of the 6th P.M., and Sections 30 and 31, Township 6 North, Range 66 West of <br />the 6th P.M., as shown on the attached Figure 1. Mining operations will occur in several phases and <br />are expected to last approximately 5 years. Due to restrictions related to eagle nesting habitat, <br />MM will mine different areas of the site during different times of the year. It is anticipated that <br />mining operations will occur in Phases 1A, 1B, and 1C during this plan period. No ground water has <br />been exposed in Phase 1A or 1C yet. A contemplated “first fill” of Phase 1C discussed in the <br />previous SWSP did not occur. Once ground water is exposed, all phases of the mine will be <br />continuously dewatered for the entire plan period. The depletions that are projected to result <br />from the mining operations over the period of this SWSP include evaporation from exposed ground <br />water, water removed with the mined product, and water used for dust suppression. The proposed <br />replacement sources are a combination of 12 Whitney Ditch shares owned by MM, water stored in <br />MM’s Heaton Reservoir, and/or excess reusable effluent leased from the City of Greeley. <br /> <br /> <br /> <br />
