Paue 12 of 20 <br /> 71. Exhibit G—Secad 4—HRRQ access road 100 year 24 hour event—why is this 100 year <br /> storm design included? Will culverts be designed for 10 year storm event(as previously <br /> mentioned) or 100 year event? <br /> (N.Reed) <br /> 72. Exhibit G-Secad 4- TSl-CC-1 & LTC-CC-1 thru LTC-CGS shown as 100 ft culverts-is <br /> that the planned length for these culverts? <br /> (N. Reed) <br /> 73. Exhibit G-Secad streamstats version 3 -states warning disclaimer "selected watershed <br /> partly in area for which flow equations not defined..."-has operator confirmed that the <br /> estimates are applicable & appropriate for this site?Has operator discussed rainfall <br /> estimates with DWR? <br /> (N.Reed) <br /> 74. Exhibit G-BBA memo -pg 5- what data needs to be collected to better determine whether <br /> groundwater would be encountered in south westportions of mining area where data not <br /> available? <br /> (N.Reed) <br /> 75. Exhibit G-BBA memo -pg S-states no water supply wells in southern half of Sect 16, SE <br /> quarter of Sect 17, or all of Sect 20 and 21 -but there's vacant land owned by people within <br /> Eagles Nest in Sect 17 now- what happens if wells drilled there in future? Could they be <br /> impacted? <br /> (N.Reed) <br /> 76. Exhibit G-BBA memo-pg 6-they recommend installation of 2 monitoring wells before <br /> mining begins to quantify & confirm groundwater changes not occurring in water supply <br /> wells west& east of proposed mine- will operator follow this recommendation? <br /> (N. Reed) <br /> 77. Ex g-bba memo-pg 6— "monitoring wells will provide data to confirm water level <br /> conditions in event a neighboring well owner claims op has detrimentally impacted water <br /> levels in their well"-if western monitoring well doesn't tap same rock fractures as wells loc <br /> above quarry, how would that monitoring well effectively determine whether wells impacted? <br /> (N.Reed) <br /> 78. Ex g-bba memo-states local aquifer& stream system will not be developed for water <br /> supply purposes-contradicts earlier op statement(pg G-16) that they may use hrr water or <br /> may drill wells-which correct? <br /> (N.Reed,J.Moore,K.Moore) <br /> 79. Ex g-fig 3 well water location map-not all eagles nest wells included-incl one that's <br /> probably closest to proposed quarry area- what process used to identify & select wells for <br /> this map? <br /> (N.Reed) <br /> CO' <br /> 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us Fz s <br /> John W.
