ORIGINAL -PUBLIC FILE <br />(Page 2) <br />MINE ID # OR PROSPECTING ID #: nn-I9R/.-nI s <br />INSPECTION DATE: SL4/nx INSPECTORaS INITIALS: ~1~. <br />OBSERVATION <br />The Division conducted a monitoring inspection of the site as part of sites to be inspected during the fiscal years <br />2006 and 2007.The mains purpose of the site inspection was to verify the type of impervious layer the operator <br />plans to implement either a cloy liner or a slurry wall. Operator had been conducting reclamation work in the <br />Pueblo West permit M-1977-573 CONSTRUCTING A CLAY SEAL ALONG THE Arkansas side of the pit to limit water <br />infiltration so the pit floor can be reclaimed. The Pueblo East permit was approved for a slurry wall construction, <br />however, Continental MATERISLAS with the approval of the State Engineer has been lining the wall in their <br />Pueblo Pit with clay liner and wanted to see if they could meet the leak down test for such structures. If the liner <br />worked, rather than constructing the slurry wall they wanted to change it to clay liner along the embankment <br />of the pit wall along the Arkansas River via a technical revision. The Division did not object to extending the <br />time frame because, operator has been collecting ground water data for the area that will be impacted. <br />There are a few domestic well that will be impacted by the placement of such a structures, so the added time <br />gave the operator to conduct experiments such as replenishing the ground water for these wells by pumping <br />water towards these areas via ditch structure. Apparently, the experiment appeared to have only measurable <br />success. The only option for the operator is to drill a deeper well below the shale to make sure these wells are <br />not impacted by the placement of the restrictive clay during the mining operation along the west side of the <br />permit area. <br />The entire site was driven walked and inspected. Site was active at the time of the inspection. Operation <br />consists of a long conveyer system, front-end loaders and dozers, wash plant and settling pond with an NPDES <br />discharge permit. Active pit area currently covers approximately 40 acres with a total affected area of 103 <br />acres. Topsoil stockpile properly protected. Large quantity of Processed material stockpiled along the West side <br />of the wash plant area. According to the approved Amendment, the areas covering the concrete batch plant <br />even though all the maps show them to be with in the permit area, these structures are actually not part of the <br />mining operation. The batch plant is approved to accept materials from other sources. Since all the associated <br />buildings with the batch plant are not regulated by the DMG permit, to make it clear for other who will inspect <br />the site, it is recommended by the Division that the operator, Transit Mix, submit a New Mining and Reclamation <br />map delineating these areas from the permit with in 60 days from receipt of this inspection. The maps should <br />include a letter stating why it was needed to remove these structures from the permit, so they will not be <br />considered a warranty liability. The submittal should also include the length and width of the conveyer system <br />and the warranty for removal of the conveyer system, which was never included in the warranty calculation for <br />the site. The existing warranty for the site $1,160,000.00 appears to be adequate to cover the current and <br />anticipated disturbance with the exception of the conveyer system <br />I & E Contact Address <br />NAME: MR.PETE MELCHER <br />OPERATOR: CONTINENTAL MATERIALS CORP <br />STREET: 444 FACT C'C)SII I A STRFT <br />CITY/STATE/ZIP: rnl t~RAnn ePRw~S rn 9o9n~ <br />cc: <br />Harry Posey (e-mail) <br />cc: r CE <br />r BL <br />r FS <br />r HW <br />r HMWMD (CH) <br />r <br />
