(Page 2) MINE ID # OR PROSPECTING ID #: M-1997-054 INSPECTION DATE: Z/ii1n INSPECTORS INITIALS: -RK- OBSERVATIONS The Division conducted a monitoring inspection of the site on 7/31/10, as part of sites to be inspected during the fiscal years 2010-2011. The site is a 513.2 acres permit area consisting of a sand and gravel operation along the south west side of the permit and a granite quarry along the north east side of the permit area. The maximum acres that can be affected at any given time are 200 acres. Warranty for the site is $1,174,724.00 Present during the inspection was Mr. Terry Tew, the plant manager for the operation. Permit sign, boundary and affected area markers were properly posted. The entire area was driven walked and inspected. With the exception of routine maintenance like the settling pond cleaning and other mining area routine, the site was not actively producing aggregate. The operator had cleaned up most of the non mine related waste material that was noted during the last per operational inspection in 2007, when an amendment to the site was submitted. Large quantities of processed material from the sand and gravel portion of the operation were stockpiled along the southeast side of the pit area. In anticipation of mining, top soil/overburden has been removed and temporarily stockpiled along the west side of the permit area. Operator plans to utilize the topsoil/overburden during their anticipated reclamation of the area. If the top sol/overburden is not utilized within 180 days, Mr. Tew stated that it will be seeded and stabilized in place. No erosion features were noted in the already stockpiled material. The operator has placed the large oil storage tank in a properly fenced and appropriately lined area to protect from spills. The entire minor clean up request that were mentioned in the previous inspection report for the most part has been complied with. The active SDG mining area was dry at the time of the inspection. No shallow GW was exposed at the time of the inspection. Operator has a SEO approved adequate water substitute supply plan for the operation. The sand and gravel requires washing to remove fines. Te large old processed material with lots of fine along the South East side of the active mining and stockpiling area was still in place. Side slopes stable. Mr. TEW said, Front range aggregates plans to find use for it soon, once the current market condition changes. All of the material from the site is hauled by rail that is owned by the operator. The storm water control structures for the site were found to be in good repair. As stated earlier, an excavator was cleaning the east side settling pond at the time of the inspection. Three settling ponds and a fresh water pond are utilized in the processing of the aggregate from the sand and gravel side of the operation. The north side f the permits traversed by the Tallahassee Creek. Both the west side bridge and the East side crossing had been washed out. The West side bridge was washed out during the past rain storm in 2010. The east side crossing to the granite quarry is was washed out in 1996. Since the operator did not affect any of the areas amended in 2007 associated with the granite quarry operation, the Division did not see the need to inspect the area. Mr. Tew is aware of the stipulation associated with the granite quarry and assured the Division that if and when the operation starts mining the quarry, the requested information will be provided that will fulfill the amendment approval for the site. The operation is in compliance with the approved permit. No warranty calculation is needed at this time because the operation has not even started in the quarry area. I & E Contact Address NAME: MR.
