PERMIT #: M- 2004 -030 <br />INSPECTOR'S INITIALS: MAC <br />INSPECTION DATE: April 25, 2012 <br />occurring during the mining operation or reclamation. The possible violation will be scheduled for the June13- <br />14, 2012 Mined Land Reclamation Board Hearing. Notice of such hearing will be sent under separate cover. <br />Revegetation: <br />The Division observed diffuse knapweed throughout the site. Diffuse knapweed is commonly found in quarries <br />throughout this part of Boulder County. Diffuse knapweed occurs on the Colorado State Noxious Weed List B, <br />which requires the development of a weed control plan designed to stop the further spread of this species. <br />According to the Operator, the diffuse knapweed is treated by releasing weevils which feed on the roots of the <br />plant. The Division reviewed the permit file and could not find an approved Weed Control Plan; any site with <br />noxious weeds present must have an approved Weed Control Plan on file with the Division. This has been <br />cited as a problem and will require corrective action by the Operator; please see the first page of this report <br />for additional information. <br />Financial Warranty: <br />The Division currently holds a financial warranty in the amount of $20,300.00; the financial warranty was <br />based on a maximum disturbance of 8 acres. As noted earlier in this report, the total disturbance at this site <br />was found to be 10.61 acres. Therefore, the Division has reason to believe the financial warranty for this site is <br />no longer adequate to complete reclamation. Pursuant to Rule 4.2.1(1), all financial warranties shall be set and <br />maintained at a level which reflects the actual current cost of fulfilling the requirements of the Reclamation <br />Plan. The Division will recalculate the financial warranty amount for this site; notice of any increase of the <br />financial warranty amount will be sent under separate cover. <br />This concluded the inspection. <br />Page 4 of 6 <br />
