September 14, 2005 <br />Not applicable to this revision. <br />The cover letter indicated that a propane storage tank would be placed on the 6 North Shaft <br />pad but no dimensions were provided. In other locations Twentymile Coal Company has <br />erected concrete cradles for fuel tanks on similar ancillary facilities. Please have the operator <br />provide information on the size of the propane tank proposed, and information regazding how <br />it will be stored. I.e. will the tank rest on concrete footers, etc.? <br />Not applicable to this revision. <br />4. I have concern regarding windrowing topsoil on the downhill slope of the access road. If the <br />operator chooses to use windrowed topsoil stockpiles, placement on the uphill slope provides <br />better protection of the topsoil resource. Rule 4.06.3(2). Adequate signage of the topsoil <br />stockpiles is necessary. <br />Topsoil piles will be on either end of the 2,450 foot-long road. Each 4,6000 cu yds. No longer <br />in windrows. See map EX16E-M1. <br />The total reclamation cost estimate for tasks specific to TR-48 is $166,395.00. Reclamation tasks <br />sheets aze included with this memo. <br />
