To: Jared Ebert Date: December 29. 2017 Page 21 more than 72 hours, a permanent plan for augmentation must be obtained from the Colorado Division of Water Resources. Response 41 LRM's primary plan is to obtain the water rights needed to capture and retain stormwater after reclamation. Swales are planned around the site perimeter after closure to manage stormwater and divert it to internal sumps. Should water rights not be obtained for long- term augmentation, LRM plans to return captured stormwater to the watershed (see Attachment 2—Exhibit F, sheet 1). RULE 6.4.8 EXHIBIT H - WILDLIFE INFORMATION Comment 43 Section 10.2.1 states, "all trees within the project area will be considered as suitable nesting habitat for migratory birds. " Please provide a monitoring plan that will allow LRM to identify newly established nests within the permit area prior to affecting areas near trees. Please provide a plan on how these nests will be protected if they are identified. Response 43 Due to location of sand and gravel mining sites in rural areas along riparian corridors, mining often coincides with nesting birds. To minimize potential effects to any raptor nests that may be built within the perimeter trees during mining, LRM will institute the following measures: • The site will be surveyed during August of every year, to insure there are not any nests within 600 feet of the scheduled mining area for the next year. • Mining activities that are to take place within 400 feet of any identified nests will be adjusted to start during the non-nesting season (September through February) so that the birds will be exposed to activity before the nesting season starts. It is assumed that if the level of activity is not acceptable to the birds they will use an alternate nest site further from the mining activity. • Use of conveyors in lieu of hauling material on trucks will minimize any disturbance created by transporting material. • No mining will be allowed within 400 feet of an active raptor nest during nesting season. This plan has proven successful at LRM's other mining sites. Response to DRhtS comments T E L E S T
