SCOT?.SMITH I~03-728-3403 JRN X6'95 901 No.001 P.03 <br />MINING PLAN <br />Please indicate what sediment control structures or site features <br />will ensure that disturbance to surface water quality, both during <br />and after mining, will be minimized. <br />How much water is anticipated to be used during gravel washing <br />operatioaa and how will it be handled such that an NPDBS permit is <br />not required? <br />The application indicates that no highwalls will be left after <br />reclamation. Please indicate whether mining operatioaa will end <br />with a highwall that requires backfilling, or if mining operations <br />will elope the pit floor so that a highwall does not exist nt the <br />end of mining. Please provide detailed information regarding the <br />appropriate mining method. <br />What measures will be taken to remove vegetation from the Bite <br />before topsoil salvage begins? Will vegetation ba ground in to the <br />soil or grubbed and removed? Please be specific about methodology. <br />The Soil Conservation Service report indicates that adequate <br />topsoil ie present to cover the site to a minimum depth of six <br />inches. To ensure adequate soil quality and quantity for <br />successful revagetaCion, topsoil selvage should be conducted to <br />segregate and store the overburden separate from the topsoil. <br />Please commit to segregation of the overburdea from the topsoil end <br />to salvaging enough to eoi volume to cover the disturbed area with <br />a minimum of six incheB of topsoil. <br />Please indicate the elevation of the wetlands described in Bxhibit <br />G and what it's water source is. Is it possible for the mining <br />operation to affect the water quality or quantity at this wetland? <br />RECLAMATION PLAN <br />The reclamation plan map shows the average slope of the reclaimed <br />surface to be approximately 4: 1; however, the uppermost contours <br />illustrate a slope steeper than 2:1. Pursuant to Rule 3.1.5(2) sad <br />(7), please demonstrate how backfilling and compaction will be <br />performed to assure adequate stability and compatibility with the <br />proposod end land use. <br />Pursuant to Rule 6.4.b(2)(e), please provide a schedule or <br />timetable indicating how and when reclamation (and reclamation <br />.phases) will be carried out. <br />Please commit to replacement of a minimum depth of six inches of <br />topsoil on the entire disturbed area to be reclaimed. Also, <br />indicate what eoi2 conditioning methods will be employed before <br />seeding. ie: harrowing, dieting, chisel plowing etc. <br />The application indicates the*. topsoil wilt be stockpiled fur the <br />thirty year life of mine. Storage for this extended period of time <br />
