Inspection Contact Address <br />Mark Johnson <br />Bestway Concrete Company Inc. <br />301 Centennial Dr. <br />Milliken, CO 80543 <br />OBSERVATIONS <br />PERMIT #: M- 1996 -060 <br />INSPECTOR'S INITIALS: ECS <br />INSPECTION DATE: January 10, 2013 <br />This was a routine site monitoring inspection conducted by DRMS at the Firestien Pit site. The inspection was conducted <br />by Eric Scott of DRMS. DRMS travelled to the site with Mark Johnson of Bestway Concrete at approximately 1100. The <br />site entrance is located off the west side of 83` Ave just south of where it intersects County Road 64 (also known as "0" <br />Street). The site is WNW of the Town of Greeley in Weld County. <br />DRMS toured the site with the Mr. Johnson. Current excavation activity in the mine is located primarily on the Tigges <br />property with cement production and sales of stockpiled material continuing on the original site. The mining and <br />reclamation of the Roberts parcel is completed as residences and a ski lake. Several areas within the site were marked as <br />"jurisdictional wetlands" so care will need to be taken to prevent disturbing these areas. According to DRMS records, no <br />portion of this site has been released from the permitted area to date. <br />The bonding issue noted on the first page of this inspection report is a result of failure to address exposed groundwater <br />issues and the resulting bonding liabilities as described in the letter sent out to all operators in February of 2010. There is <br />a currently a significant amount of exposed groundwater at this site, and at this time the bonding liability for this has not <br />been addressed. Any areas of exposed groundwater that are not currently part of a submitted or approved permanent <br />augmentation plan will need to be backfilled, or sealed from the alluvial aquifer with a clay liner or slurry wall that will <br />pass SEO approval criteria. As an alternative, Bestway Concrete may also commit sufficient water rights for all exposed <br />groundwater to be applied to a permanent augmentation plan for the site. This commitment of water rights would need to <br />be made in an approvable format to the SEO's office, and documentation of SEO approval would need to be provided to <br />DRMS. At this time, to avoid possible enforcement actions, Bestway Concrete will need to identify how each area of <br />groundwater exposed at the site will ultimately be dealt with and bonded for in a manner that will comply with the <br />requirements of the February 2010 letter by the corrective action date shown on the first page of this report (2/10/13). <br />DRMS will review the updated bond calculations submitted for the site by Bestway, or calculate a new bond for the site <br />that will include the necessary modifications for addressing groundwater exposure and the associated costs based on what <br />methods Bestway chooses to address the exposure of groundwater at the site. When the appropriate updated bond for the <br />site has been determined, the updated bond amount will be specified in a forthcoming surety increase as described on the <br />first page of this report. <br />Page 2 of 3 <br />
