Mr. Connor Drinkard <br /> RE: Carr Pit East M-2022-005 <br /> June 27, 2022 <br /> reclaimed site will occur around the excavation exterior, but will always be 3H:1 V or flatter. <br /> Surface roughening and active management during final reclamation will be used until <br /> vegetation establishment stabilizes slopes. These slopes, however, direct stormwater back to <br /> the interior of the site and not off the permit area or directly into Lone Tree Creek. <br /> On the interior of the site, slopes will be graded to reflect the pre-mining landform (generally <br /> 2 percent slopes or flatter). Again, surface roughening and active management will be the <br /> primary practice until vegetation becomes established. The site interior grading will direct <br /> runoff towards the undisturbed Lone Tree Creek drainage. <br /> 20. Reclamation phasing will generally follow mine phasing. Details of the concurrent <br /> reclamation are presented in Exhibit E — Reclamation Plan. As described in Exhibit D — <br /> Mining Plan, once the mining highwall has exposed approximately 500 feet (perpendicular to <br /> the highwall) of new excavation, reclamation begins on previously disturbed areas of the <br /> excavation with scarifying/rough grading and soil/growth medium placement as soon as <br /> material becomes available. Final grading and revegetation are typically timed to take <br /> advantage of the spring growing season. <br /> The table below provides an overall summary of reclamation phasing. Because of the Carr <br /> Pit East site conditions and climate, several years may be needed to finalize reclamation as <br /> illustrated in the reclamation summary. <br /> Reclamation Phasing Summary <br /> Total Acreage Duration <br /> Mine Phase Mine Area (acres) (years) <br /> Phase I North 102.7 8-11 <br /> Phase II South 23.2 4-5 <br /> TOTAL 125.9 12-16 <br /> 21. All stockpiles of topsoil and overburden material inactive for 180 days will be seeded. <br /> 22. The use of fertilizer and mulch at the Carr Pit East site is not desirable nor anticipated. If it is <br /> determined that fertilizer and mulch is needed to achieve successful reclamation, additional <br /> soil analyses and other information may be necessary to prescribe the appropriate fertilizer <br /> application. If it is determined that fertilizer and mulch are necessary for reclamation, the <br /> supporting information and application plan will be submitted to the Division in a technical <br /> revision prior to use. <br /> 23. As stated in Exhibit E — Reclamation Plan, seeding shall occur in areas when grading and <br /> spreading of topsoil/overburden growth medium are complete. Planting will occur <br /> seasonally to allow for timely germination with available moisture and to provide the highest <br /> Ws <br /> �bue earth Page 7of12 <br />
