Figure 19, <br />Typical Design of Contour Furrow, shows that the check dams will be installed at 24-foot <br />intervals. <br />Pursuant to 2.08.4(5)(c)(ii), the DMG shall post public notice of this decision in our <br />Denver office. Pursuant to 2.08.4(5)(c)(iii), within the 10 day period following the <br />posting of the public notice, any person which has an interest which is or may be <br />adversely affected, may request a formal hearing on the decision. If the DMG does not <br />receive a written request for formal hearing by May 8, 1995, the decision shall become <br />final. <br />Please contact me if [can be of greater service. <br />Sincerely,-~/ /~ <br />Wallace H.
