L_ I <br />r INFILTRATION RATES <br />Table II shows the minimum infiltration rates in inches per hour for classifying the soil: <br /> <br /> <br /> <br />1 <br />TABLE II <br />GROUP MINIMUM INFILTRATION RATE <br />INCHES/HOUR <br />A 0.30 - 0.45 <br />B 0.15 - 0.30 <br />C 0.05 - 0. I S <br />D 0.00 - 0.05 <br />' The infiltration tests that were made at the proposed mining site resulted in an extremely high <br />' infiltrator rate because of the gravel/sand deposits in the area. Test results of 3 tests are shown in <br />TABLE III. <br />t <br /> <br /> <br /> <br />TABLE III <br />TEST NO. RATE <br />TEST NO. 1 1.56 INCHES/MfNUTE <br />TEST NO. 2 1.50 INCHES/MINUTE <br />TEST NO. 3 1.50 INCHES/MINUTE <br />The hydrologic soil classification for the sub-basins is somewhere between classification "A" and <br />' "B", and judging from the soil consen~atior, maps for Fremont County, the "A" classification is <br />' closest to the existing conditions because of the many graveVsand deposits encountered throughout <br />this region. <br /> <br /> <br /> <br />PAGES <br /> <br />
