Poudre Pits Combined SWSP Page 6 of 9 February 26, 2015 For any gravel pit whose reclamation includes unlined ponds, a plan of augmentation approved by the water court must be obtained to cover the long term evaporative depletions. Until an augmentation plan is obtained the operator may post a sufficient bond to backfill or line the site thereby eliminating any long term augmentation requirements, or permanently dedicate shares that will be used in an augmentation plan to the pit. For any gravel pit whose reclamation includes lining or backfilling of the pit, bonds must be posted that can be used to complete the reclamation plan should the operator walkaway from the site. The North La Poudre and La Poudre pits have been bonded through DRMS and are in compliance with the April 2010 DRMS letter (approach #1 and #3). The Roberts phase within the Firestein /Tigges /Roberts pit is augmented under the plan for augmentation approved in case no. 2002CW331 and is in compliance with the April 2010 DRMS letter (approach #2). An inspection by the DRMS on January 10, 2013 found the bond for the Firestein and Tigges phase within the Firestein %Tigges /Roberts pit to be inadequate. The operator has since obtained a new bond and is in compliance with the April 2010 DRMS letter (approach #1 and #3). A summary of each pit's status regarding their long term augmentation and bonding held through DRMS is shown on the following table: Table F - Final Reclamation Summary Site DRMS Proposed Final Bond Name Permit # Reclamation Amount Comments Firestein Unlined Ponds Operator increased reclamation liability bond on 6/17/2014 to comply with DRMS requirements for Tigges M- 1996 -060 Unlined Ponds $1,917,925 exposed groundwater on site.
