Final -Restoration and Compliance Plan for May Day Idaho Mine Complex <br />Administrative Order for Compliance, Docket No. CWA-08-2012-0011 <br />2. Sediment and erosion controls will be installed, per the Stormwater Management Plan <br />for the mine. <br />3. Trucks and equipment will use designated access areas. <br />4. Areas for disposal of any excess soil and rock will be located in uplands away from any <br />wetlands, Little Deadwood Gulch, and the La Plata River. <br />5. The work will be observed in the field by a qualified wetland scientist to ensure <br />compliance with the plan. <br />5.5 ACTUAL RESTORED PHYSICAL CONDITIONS <br />Photographs will be taken of the work. Construction observations will be recorded on a <br />standard form. An as-built drawing will be prepared for the Chief Portal site and submitted to the <br />USEPA/Corps within six weeks of completion of the work in this Plan. The area of the additional <br />mitigation will be measured and an-built drawing prepared. <br />5.6 SUCCESS CRITERIA <br />The goal of the work at the Chief Portal is to stabilize the Little Deadwood Gulch channel while <br />providing the required mine egress for safety. <br />The goal of the work at the Mine Access Road along the La Plata River was to stabilize the <br />existing retaining wall and slope and re-construct the mine road according to the plan and <br />engineering standards. <br />The goal of the mitigation is to replace the fu~ctio~s provided by the impacted wetlands. <br />Success criteria for the existing mitigation sites, which are from the authorization for the March <br />4, 2008 NWP 14 Mitigation Plan, were provided in Section 2.1. <br />Performance Standards (also known as success criteria) for the additional 0.079 acre of <br />emergent wetland to be created were developed from the South Pacific Division Uniform <br />Performance Standards by the Corps and are shown in Table 4. The standards in Table 4 are <br />generally consistent with the success criteria for the existing mitigation sites, and they address <br />wetland soil, vegetation, and water supply. <br />June 2016 Bikis Water Consultants, a division of SGM Page 15 <br />Case 1:16-cv-02008-WYD Document 2 Filed 08/08/16 USDC Colorado Page 45 of 82
