Page 4 <br /> Mr. Rob Zuber <br /> June 3, 2022 <br /> soil will be stockpiled. The Mining Section now includes, " Scrapers and/or bulldozers will strip the <br /> topsoil of any affected land prior to mining or stockpiling. Topsoil will be segregated and stockpiled <br /> either in berms around the mine pits or in the processing area." <br /> 14) Exhibit D needs to include a discussion of stabilization of topsoil stockpiles. Reference <br /> Exhibit E, as appropriate. The following language has been included in the Mining section of the Mine <br /> Plan, "Topsoil stockpiles and berms that remain dormant for fourteen days shall be roughened, <br /> mulched, or tackified to stabilize them.Topsoil stockpiles that remain in place over 180 days will be <br /> seeded with the seed mixture described in the Reclamation Plan." <br /> 15) Exhibit D should include a discussion of the structures that will be constructed for the <br /> mining operation, including dimensions and general construction methods. (For example, <br /> will foundations include rebar reinforcement?)The only structure to be constructed at the site will be <br /> the drying and screening building,the scale and the scale house. The scale will be approximately <br /> 70'x 10' and will sit on concrete footers.The scale house will be a portable modular building.The <br /> drying and screening building will be approximately 250'x 50' and will sit on a reinforced concrete <br /> foundation. <br /> 16)The mining plan should include a discussion on erosion prevention on the steep slope at the <br /> northwest portion of the permit area, especially where the conveyor will be built between <br /> the boundary and Cell 4. The conveyor has been moved to pass between Cells 3 and 4. The area to <br /> the northwest of Cell 4 is planned to remain undisturbed and the native vegetation will act as <br /> erosion protection. The site will prepare a Storm Water Management Plan prior to site disturbance <br /> to control for erosion. Disturbed areas with steep slopes will be roughened, mulched, or tackified to <br /> stabilize them. <br /> 17) Provide a discussion of existing buildings, other structures, and easements within the <br /> disturbance area. This should indicate if structures and easements will be relocated or <br /> removed. A particular area that should be addressed is the area within Cell 4. A Structures section has <br /> been added to the Mine Plan. <br /> 18)The following text(or similar)should be added to the exhibit: "Prior to starting construction <br /> of any slurry wall, the applicant shall apply for a Technical Revision with a slurry wall design <br /> report." This text has been included. <br /> 6.4.5 Exhibit E- Reclamation Plan <br /> 19) The text needs to include details for revegetation, including details on seed bed <br /> preparation, the reclamation seed mix, seeding rate, application method, and the time of <br /> seeding. Also, include details for planting, if applicable. I have added the proposed seed mix to the <br /> Reclamation Plan. In subsection (d)the seed bed preparation is noted as, "The topsoil shall be <br /> keyed to the underlying and surrounding material by the use of harrows, rollers or other equipment <br /> suitable for the purpose." The application method is noted as, "seed will be drilled and mulched" <br /> and the time of seeding is noted as, "between late September and the middle of April." <br /> 20) On Page 3 of Exhibit E, the text states that stockpiles remaining in place for more than one <br /> growing season will be vegetated. Please commit to seeding stockpiles which have been in <br /> place for 180 days and provide a seed mixture, including pounds of pure live seed (PLS) per <br /> acre. Text has been changed to 180 days. <br />
