ACHNICAL REVIMON III �II�I999II��II III <br /> Date: Friday 16 August 1996 <br /> To: Gregg Squire <br /> Colorado Division of Minerals & Geology <br /> Office of Mined Land Reclamation <br /> 1313 Sherman St., # 215 <br /> Denver, Colorado 80203 .. „_ <br /> FAX #: (303) 832-8106 <br /> From: Bradford Janes 2 Ally 9�8 <br /> 173G <br /> Professional Forester <br /> P.O. Box 5538 u,v Ueoiogv <br /> Arvada, Colorado 80006-0538 <br /> (303) 427-9419 <br /> For: Varra Companies, Inc. <br /> 2130 South 96th Street <br /> Broomfield, Colorado 80020 <br /> FAX # (303) 666-6743 <br /> Subject: Addendumto the TECHNICAL REVISION for Pit 1 - Permit M-74- <br /> 052. <br /> Warranty determination and descriptions of affected land follow in Tables 1-3 <br /> below. Features determined from aerial photography and computer aided <br /> measurement and mapping reflect a potential error of measurement from <br /> section, aerial photograph, planimetering of 3.7± percent greater than that if the <br /> section measurement was a square mile, which they seldom are. The section <br /> appears to be 200± feet longer North to South, which may or may not reflect <br /> reality, but is probably of greater accuracy than the assumed square mile of the <br /> original submittal and map. Therefore, the area measured and costs reflected <br /> below are cushioned by this error, at least, and reflect the more liberal <br /> measurements. <br /> The reduction/release is related as much to improved accuracy of measurement <br /> and greater reliability of the nature and extent of disturbance as it is to release <br /> of substantial areas. For areas where release is indicated, a separate letter <br /> requesting release will follow to more fully conform to Rule 4.16. Until that <br /> time, those areas indicated for release are included in the revised warranty <br /> determinations. <br /> Varra Companies, Inc. - Pit 1 - DMG Permit M-74-052 1 <br /> Addendum - TECHNICAL REVISION - 08/16/96. <br />
