This technical revision consists of. <br />1) Incorporation of new site roads into the mining and reclamation plan <br />2) Confirmation of the amount of active pond area available to the operator at any time. <br />Each of these items is addressed below. <br />1. Incorporation of new roads <br />A 12 -foot wide gravel road now connects the Gloria Z Pit to the neighboring JRS Mining <br />operation to the east. This road has been installed to facilitate trucks hauling material from one <br />site to the other for processing. Sediment catch basins are installed within the road to prevent <br />stormwater from leaving the site. The caught stormwater infiltrates into the exposed rock, which <br />is highly permeable. <br />A second road runs along the north and northeast portions of the site. This road is used to access <br />the collection ditches in that area. Since this road is located within the drainage area that flows to <br />the collection ditches, no additional sediment control is needed. <br />These roads will remain after mining and reclamation, therefore no additional bond will be <br />needed to cover them. <br />2. Active Pond Area <br />The total active non -sediment pond area is now roughly 1.3 acres. These are the ponds in the <br />central part of the site, related to the processing of mined material. All of these ponds are located <br />in the area of main reclamation, and therefore will be backfilled as part of the regrading activity <br />that will already take place. <br />The currently approved maximum processing and water handling pond areas covered by the <br />approved DRMS permit is 1.37 acres. Therefore, no revision is needed on the total pond area at <br />this time. <br />Gloria Z Pit 1 (;ft%lxwkkiand nmodatmPUA' <br />
