6.4 SPECIFIC EXHMIT REQUIREMENTS — REGULAR 112 OPERATIONS <br />The following items must be addressed by the Operator in order to satisfy the requirements of C.R.S. 34-32.5-101 <br />et sem. and the Mineral Rules and Regulations of the Mined Land Reclamation Board: <br />EXHIBIT D -Mining Plan (Rule 6.4.4): <br />5. hl accordance with Rule 6.4.4(e), please provide a description of the size for each tract as proposed in the <br />mining plan. <br />The future tracts do vary somewhat in size due to topography. As a new tract is opened, it will <br />have boundary stakes put in place, the Division will be notified, and the acreage determined. <br />6. The Operator states the Division will be notified as new tracts are opened. If the Operator intends to operate <br />as a phased mining/bonding approach, please commit to contacting the Division for approval prior to <br />disturbing any new tracts. The request shall include the estimated reclamation costs that would be required for <br />opening the additional tract. The Division will review and calculate a new Finical Warranty amount, issuing a <br />Surety Increase revision, as necessary; once the additional amount is posted the Operator will be approved for <br />the new tract. <br />Please note that the Operator may, at any point throughout the life of the mining operation, request a <br />Surety Reduction for completed reclamation tasks or an Acreage Reduction for portions of the permit that <br />have achieved final reclamation.*** <br />We will commit to contact the Division prior to opening new tracts. Said notification will <br />include an estimate for reclamation costs for that specific tract. We recognize that as a new <br />area is opened, the Financial Warranty requirement will increase to cover reclamation <br />requirements. We also anticipate closing old tracts as new ones open in hopes of minimizing <br />the Financial Warranty requirement. <br />7. In accordance with Rule 6.4.4(gxii), please state the nature of the stratum immediately beneath the material to <br />be mined. <br />The stratum beneath the material being mined is a dense clay material. <br />8. Please further clarify and describe the screening process as described in the mining plan. <br />Depending upon material needs, some material may be screened to meet standards required by the <br />purchaser. An aggregate screen will be employed to provide a standard material. <br />9. During the October 6, 2014 inspection of the site, the Division observed a large stockpile, approximately <br />7,000 CY, of material which had been imported to the site from a nearby highway construction project; this <br />material was planned to be blended with the sand/clay mined at the site to make foundation fill. If the <br />Operator intends to continue this practice of importing off-site material to blend with the material mined at the <br />site to make a better product, further clarification is needed; additionally within this clarification, the Operator <br />should include a description of an estimated volume per year of imported material, and a signed affidavit <br />stating that the material will not be backfilled as a part of the site's reclamation (if the Operator intends to <br />backfill this material, an Inert Fill Notice will be required).
