Liner design and quality control <br />plan are included as Attachment A and Attachment B, respectively. <br />1. According to Blue Earth Solutions (BES) December 2013 report, Table 1 on page <br />3, bedrock elevation varies between 4488 and 4501 feet above mean sea <br />level. Non - dewatered static groundwater elevation was established by BES <br />at approximately 20 feet above bedrock. <br />2. The pit floor of Phase I Parcel 2 is backfilled to 15 feet above bedrock. To achieve <br />backfill elevation to two feet above static water level, approximately seven <br />feet of backfill or 100,000 yd will be necessary. Phase I Parcel 4 pit floor is <br />backfilled to approximately five feet above bedrock. <br />6.4.12 Exhibit L: Reclamation Costs <br />3. Tables 2 and 3 are Fremont's reclamation cost estimates for phases not intended <br />-° to be reclaimed as lined water storage (Tables 2 and 3). ASI provided liner <br />construction estimate for Parcel 4 of Phase I and Phase III (Tables 4 and 5). <br />4. Fremont Paving commits to Division notification and posting appropriate <br />additional bond prior to entering the next phase of mining. <br />C n \0 /ii�onq Mq eo �L� Lcc rrnat \V /e� Ilnc„ <br />Page 1 of 6 1107 Main Street, Canon City, CO 81212 <br />www.envalternatives.com • e -mail: eai @bresnan.net <br />Phone: 719 - 275 -8951 • Fax: 719 - 275 -1715 <br />
