Therefon•e, we request approval for a change in WRN's monitoring <br />plan to include only the hvo stream gauging stations on Yellow Creek. The two <br />stations are know as Corral Gulch and Yellow Creek at White River. WRN <br />understands the value of all four gauging station for collection of regional data. In <br />the future if there is no other company required to participate in the Ryan Gulch and <br />Piceance Creek at White River stations, WRN will resume the responsibility for all <br />four stations, Section II of WRN's Monitoring Plan would be revised (as shown on <br />attached page 25), if this proposal is approved. <br />Also, per our discussion with your staff, WRN requested a Mine Plan change (see <br />attached pages 25 and 26) of Volume 5. The proposed change would be from <br />density to specific gravity once per shift or 2 per day, and bicarb production in <br />grams/liter from each cavity will be analysis 3 times per week. <br />If there are any questions contact me or WRN's Project Manager, Bob Warneke. <br />Sincerely, <br />~k~~z,~~ <br />Ed Baker, REM <br />E/H/S Manager <br />cc: EPA <br />DMG <br />White giver tJaheollte Minerals, Llmltad Llablllty Company <br />P.
