G-4. WATER REGULATORY INFORMATION: <br /> 1. NOTE: This site is designed and is NOT EXPECTED to have ANY STORM WATER OR PROCESS <br /> WATER DISCHARGE FROM THE SITE. <br /> 2. Storm water management/discharge: The Applicant will obtain coverage under a Colorado Discharge <br /> Permit System permit for any discharge of storm water, dewatering flows,and process water, before <br /> initiating mining activities. Coverage will be requested under the general storm water discharge permit <br /> COR500000,sand and gravel,issued by CDPHE-WQCD, as required for mining and land disturbance <br /> of this size.The CDPS permit is the equivalent of an NPDES permit for the state of Colorado. It is not <br /> planned to discharge such waters, but rather,to allow that water to infiltrate into undisturbed terrace <br /> alluvium.This exhibit(G-1)contains the information also required for the storm water management plan <br /> (SWMP). <br /> 3. Water rights/use: The landowner will provide water for mining operations by off-site purchase and truck <br /> delivery from permitted/registered sources for municipal and industrial uses, as needed. Permits for <br /> purchase, use, and transport of water will be obtained as necessary. <br /> 4. Waste water disposal and treatment: No sanitary waste water is expected to be generated by mining <br /> activities; chemical latrines and holding tanks for sanitary facilities will be used as necessary. No non- <br /> sanitary waste water is expected to be discharged from the site; if waste water is generated by mining <br /> or related activities(such as washwater), it will be retained on-site, and recycled or allowed to <br /> evaporate/infiltrate. <br /> 5. Wetlands information (USACE, NRCS,or FWS jurisdiction): Review of National Wetland Inventory and <br /> NRCS maps for the area show no wetlands delineated and inventoried in the area.
