By selecting Option B, Martin Marietta choose to not waive their right to <br />a 30 -day processing period and was required to submit a replacement Financial Warranty for the same dollar <br />amount maintained by the current Operator ($3,150,000.00). On February 1, 2012, the application was <br />deemed complete following the submittal of the appropriate financial and performance warranties. The <br />Division approved the Transfer of Permit and Succession of Operators for the Riverbend Operation on <br />February, 15, 2012. Martin Marietta is now the permitted operator of the Riverbend Operation and Lafarge <br />West, Inc. has been released from reclamation responsibility at the site. <br />Financial Warranty: <br />The Division is required to recalculate the required reclamation bond within 60 -days from the date of the <br />transfer is completed (April 15, 2012). The Division currently holds a reclamation bond in the amount of <br />$3,150,000.00. <br />The Division updated the most recent bond calculation (AM -01) to reflect current equipment and labor costs. <br />The revised financial warranty amount is $3,450,600.00, which is an increase of $300,600.00. The Division will <br />notify Martin Marietta of the financial warranty increase and provide a copy of the Division's calculations <br />under separate cover.

The <br />Operator will need to comply with the Division's letter dated April 30, 2010 addressing operations with <br />exposed groundwater prior to exposing groundwater at the site. The revised bond estimate for the site <br />includes a task to backfill the existing exposed groundwater at the old Ft. Lupton Pit located in the northwest <br />corner of the site. The short-term groundwater exposure is covered by a well permit and substitute water <br />supply plan. <br />Gen. Compliance With Mine Plan: <br />The site is inactive and mining operations have not begun at the site. The site is expected to start mining <br />following the completion of mining at the Riverbend East site in 15 -20 years. The site is currently used for <br />agriculture and oil and gas development. The Operator may need to revise the mining and reclamation plan <br />maps to account for recent the oil and gas well construction. The plan can be updated with a submittal of a <br />technical revision prior to commencing mining at the site. The structure agreements, mining offsets and <br />stability analysis may also need to be revised to account for the oil and gas infrastructure. <br />No problems were noted during the inspection.
