controls, and ground water points of compliance: Neither ground nor surface water will be intercepted or disturbed by the proposed borrow pit mining and reclamation activities. If necessary, a Stormwater Management Permit will be secured from the Colorado Department of Public Health and Environment, Water Quality Control Division(WQCD). In any event, SEMA will implement its Corporate Stormwater Management Plan which will include site appropriate Best Management Practices (BMP). A Stormwater Management Plan will be in place prior to site disturbance to ensure storm water is properly routed around disturbed areas, and/or properly controlled from the site as storm water runoff. (If required, the Stormwater Management Plan will also comply with agency requirements.) (A Stormwater Permit is only required where an operation has the possibility of a discharge to state waters or from storm water that may come into contact with any overburden, raw. materials, intermediate products, finished products,by products or waste products located at the site of such operations.) (j) Description how the Operation will comply with applicable Colorado water laws and regulations governing injury to existing water rights: • The operator/applicant will comply with Colorado water quality laws and regulations governing injury to existing water rights. It is not anticipated that any water will be encountered. If ground water is encountered, the proper steps at the State Engineers office will be complied with. • Any water used for fugitive dust control will be purchased. (k) If refuse and acid or toxic producing materials ware exposed during mining, describe how they shall be handled and disposed of in a manner that will control unsightliness and protect the drainage system form pollution: No acid or toxic materials will be used or encountered on this site. (1) Description what measures will be taken to minimize disturbance to the hydrologic balance,prevent off-site damage, and provide for a stable configuration of the reclaimed area consistent with the proposed future land use: • The hydrologic balance will not be influenced by removal of borrow material. The initial preparation of the surface before extraction of borrow material will consist of stripping the topsoil and placing topsoil in a stockpile for use later during reclamation. Front-end loaders, scrapers, excavators or other suitable equipment will be used in order to remove topsoil and borrow material as quickly as possible followed by site reclamation. The short duration of the borrow operation and timely site reclamation will minimize impacts to the hydrologic balance. 28
