With the Division's and <br />County's approval of the Amendment, which expanded the permitted acreage, gravel mining <br />commenced to the north of the azea previously disturbed. Overburden was pushed up along the <br />western, and will be distributed across the pit floor when mining in that direction has been <br />completed. The lazge draw in the middle of the permit area was filled approximately half-way <br />with compacted soil, and the grouted riprap run-down was constructed to handle flows that cross <br />the permit azea. <br />A portable crusher was in operation at the site from October to December of 2005, and again <br />from April through July 2006. The crusher produced road base materials and aggregates for use <br />in hot mix asphalt. Anew hot mix asphalt was constructed in the Cugnini Pit during the spring, <br />replacing an older portable plant. <br />Approximately one acre of ground was hydro-seeded and hydro-mulched. This occurred on the <br />2H:1 V slope at the downstream end of the draw that was partially filled. We continue to monitor <br />noxious weeds on site through the efforts of a contract sprayer. <br />The $688.00 covering the Annual Fee was mailed to your office on 07-Jul-2006. This letter and <br />the attached map are submitted as fulfillment of our reporting obligations for the year beginning <br />21-Jul-2005. <br />Sincerely, <br />`'~~`a' ~ : 4.a~o <br />Marcia L.
