According to the most current FEMA Flood Plain Map (reference FEMA Map#08-335A- 080075-Pg. 12)the proposed site is not within a flood plain. There is no surface water present directly at the site. The potential impacts to surface waters are managed through the Stormwater and BMP plan described above. We believe the proposed removal and offsite processing of the existing waste rock dumps of the Clear Creek watershed will significantly lower the potential for pollution to surface waters and groundwater in the vicinity of this project. 6F) specify how you will comply with applicable Colorado water laws and regulations covering injury to existing water rights; We do not intend to impact any existing water rights. There will be no containment structures to capture tributary surface water. No ground water wells will be installed and the removal operations will not encounter ground water. As described earlier in 6.3.3(1)(h),water for the operations will be obtained from the municipal water supply of the City of Idaho Springs. 36
