Mr. Wayland Goose Haven #2 Expansion SWSP January 9, 2013 Page 3 of 5 Applicant must insure that water is released directly from Lafayette's Goose Haven Reservoir Complex. A transit loss of 15% has been assigned to the reach of Coal Creek from Lafayette's WWTP to the confluence of Coal Creek and Boulder Creek. A letter from Lafayette confirming that as the owner they will be making replacements on behalf of RCP was provided to our office on January 9, 2012 and is attached. Tables AI.5 & AI.6 provide the required replacement schedule for these deliveries. Long -Term Augmentation Final reclamation at the site will consist of Tined storage reservoirs for Lafayette's use as a part of the Goose Haven Reservoir Complex. In accordance with the letter dated April 30, 2010 (copy attached) from the Colorado Division of Reclamation, Mining, and Safety ( "DRMS "), all sand and gravel mining operators must comply with the requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations for the protection of water resources. As the DRMS permit holder and land owner is the City of Lafayette, a bond to cover the cost of backfilling or lining the pit is not required as Lafayette is a governmental agency. As the final reclamation plan is a lined reservoir, an augmentation plan is not required to be filed in court.
