Walker to File <br />January 8. 1999 <br />Page 2 of 2 Pages <br />The report is in compliance with this rule. The Division required no written interpretation of the <br />data, but a summary of impacts is provided in the report. Impacts are reported as within the probable <br />hydrologic consequences as presented in the Permit. As stated in the preliminary repot, some <br />discharges exceeded the NPDES (Colorado) permit allowances. Annual Hydrologic Report Table <br />G96-2 headings might be more appropriately labeled. The headings cover both depths to water and <br />elevations. Minimum depths to water result in maximum water elevations, and vise-versa. The <br />headings would be more indicative of the information if they were "Highest Water Levels" (currently <br />the Minimum Water Level) and 'Lowest Water Levels" (currently the Maximum Water Level). <br />Table 18-4 might be revised to indicate critical target water by elevation in-lieu-of critical target <br />depths to better communicate the stability analysis thresholds. <br />C:\ WPDOCS\96ahrrnv.041.doc <br />CC: Dan Hernandez <br />
