and BMP maintenance. We suggest requiring a bonding mechanism to guaranty that sediment and silt are not permitted to reach North Fork Clear Creek as a result of the quarry operation. 5. Reclamation - We believe that the best chance of a successful reclamation plan described on pages 6-6 to 6-10 of the application would provide that re-vegetation be comprised only of local, native plaits, not imported plant species. Reclamation should occur when final grade is achieved and in the first window of opportunity, generally speaking that would be April/May or October/November. The reclamation should be applied by hydroseed or hydromulch and installation of erosion control blankets over the reclamation for optimal performance of seed germination. A successful reclamation plan is integral to preverving degradation of North Clear Creek over the long term. We also support the reclamation recommendations that ERO preserved to the City of Black Hawk. 6. Water Control/Diversion structure, construction, operation and maintenance - We axe concerned that the quarry operation might affect neighboring wells in the area. We would like more information on the monitoring and reporting of such impacts that the applicant wil! do. An autosampler for monitoring storm everrts should be considered and some sort of notification system for affected parties should be developed in the event a storm event breaches the retention systems. 7. Potential Water Quality Impacts -Page 11 of Martin and Wood Water Consulting letter of October 5, 2UD7 in Appendix D states "It is thus expected that the water leaving the site as storm water runoff and quarry discharge water will meet applicable standards set by state and federal agencies." We would like something stronger than the water consultant's expectation. We believe that bonding and penalties should guaranty that water runoff and quarry discharge water shall meet such applicable standards. The monitoring plan needs to be described and enforced. 8. Wastewater - We aze opposed to their proposal for the use of ports.-potties or san-o-lets for the treatment of sewage from employees. The applicant should meet the Cour-ty's standac~ds for treating sanitary sewage. 9. Bonding - In general, bonding should be sufficierv to guaranty performance of the above measures and other mitigation requirements that are required. Finally, because the Special Use Review application is insufficient in addressing the aforementioned issues and protecting the health, safety and welfare of Gilpin County and the Clear Creek Watershed, the Upper Clear Creek Watershed Association opposes the Special Use Review application and respectfully requests your denial of the application. We have had similar concerns with the Frei Quarry as well, so we are very concerned about the impacts of quarries in the Upper Clear Creek Watershed. Thank you for considering our comments.
