The presence of these habitats was identified in the initial permit application and the applicant acknowledges the recommendations provided by the CPW. However, due to the nature of an aggregate operation, the recommended construction limitation from December 1-April 30 is not feasible. Additionally, the entirety of what will be mined has historically been disturbed by agricultural operations. However, the river corridor and trees where the presence of mule deer is more likely will not be disturbed which provides a buffer for these important habitats. To protect these habitats, the applicant commits to limiting new ground disturbances to only occur out of the December 1 —April 30 window. 3. Aquatic Native Species Conservation Waters The importance of this habitat is acknowledged and measures will be taken to minimize impacts to this habitat as much as possible. The 500 foot setback year round is not feasible and not common practice as there is an abundance of similar mining operations that operate within this area. All processing operations, permanent structures, and the majority of activity will be occuring well outside of this 500 foot buffer. All mining occurs outside of the river corridor and denser vegetation that surrounds it where these species would be most concentrated. Best management practices will be used to prevent disturbances outside of the mining area and to prevent any direct impacts to the South Platte River. 4. Fencing No new fencing is planned to be constructed in this application. If fencing is constructed in the future, it will be completed following the CPW fencing guidelines. 5. Noxious Weeds and Native Re-seeding Noxious weeds and re-seeding are addressed in the reclamation section of the permit. 6. Wildlife Escape Ramps The ramp used to access the pit floor during mining will serve as the pit ramp. 7. Lighting Lighting will be limited as much as possible, and down-shielded when present. 8. Retention Ponds These recommendations will be taken into consideration. Shorelines will be irregular due to the nature of backfilling and grading of reclaimed slopes. If islands are constructed, they will be in accordance with the CPW recommendations. Colorado Division of Water Resources Comments 1. Conditions for Approval: SWSP and Gravel Well Permit Requirements An SWSP or augmentation plan will be acquired prior to obtaining a well permit. A gravel well permit will be acquired as necessary.
