slopes no steeper than 3hav and to seed the stockpiles with a temporary cover crop to <br />protect them until final reclamation. A slurry wall will be constructed around Phases 3 <br />and 3A before dewatering occurs. Phases 3 and 3A aze the phases located in closest <br />proximity to the irrigation ditches. Dewatering will remove water from the extraction <br />area only, which should insulate the irrigation ditches from any hydrologic impact due to <br />mining operations. The Division has reviewed the Applicant's slope stability analysis <br />and has concluded that the proposed setback distances from the Brighton irrigation ditch <br />during extraction are adequate. The Brantner irrigation ditch is located far enough away <br />to avoid concern about slope stability impacts. Finally, both the Brighton and Brantner <br />Ditch Irrigation Companies were notified concerning the proposed permit application but <br />neither company provided comments to the Division. <br />21. The weight of the evidence indicates that the the Applicant has complied with the <br />minimum requirements of Construction Materials Kules 3.1.6(1) and (3). <br />Issue 5: Impacts to Marilyn Kent's Water Well <br />22. Construction Materials Rule 3.1.6(1) requires an operator to minimize disturbances to the <br />hydrologic balance of the affected land and surrounding area. The Division required the <br />Applicant to agree to mitigate negative impacts to water supplies of neighbors within 600 <br />feet of affected lands. This includes the property and well of Marilyn Kent. <br />23. The Applicant has installed monitoring wells at the site to establish ground water baseline <br />levels. The Division has reviewed and approved the monitoring plan. For those wells <br />that are in use, the Applicant has agreed to attempt to measure well depth, pumping rate, <br />pumping water level, and non-pumping water level prior to mining. If so requested, the <br />Applicant will attempt to measure water levels in affected wells on a quarterly basis prior <br />
