MINE ID # OR PROSPECTING ID #: M-1974-n7n <br />INSPECTION DATE: 2-11-2nin INSPECTOR=S INITIALS: JI F <br />OBSERVATIONS <br />This was a normal monitoring inspection of the Nelson Pit, DRMS File# M-1974-070, operated by Lafarge <br />West, Inc. (Lafarge). This site is located about five miles southeast of Longmont, Colorado in Weld County. I, <br />Jared Ebert of the Colorado Division of Reclamation, Mining and Safety (Division) conducted the inspection. <br />Mrs. Anne Best Johnson of Lafarge West, Inc. accompanied me on the inspection. Lafarge submitted a <br />Technical Revision (TR-03) to the Division on January 26th, 2010 to update the current approved reclamation <br />plan. This inspection was conducted,in order to field verify the various structures and features discussed in <br />the Technical Revision. <br />This is a 360 acre site reclaimed into eight open water lakes along Boulder Creek. Enclosed with this report is a <br />copy of the map included in TR-03 submitted by Lafarge. Each of the lakes has been numbered to be used as a <br />reference for this report. The post mine land use designated for this site is recreation. Each of the lake slopes <br />appeared to be stable and graded in accordance with the approved reclamation plan. Vegetation has <br />established throughout the permit area. The vegetation consisted primarily of various grass species. The <br />upland areas surrounding the lakes appear to be used for hay production. <br />Lake #1 is located along the very southern end of the property. The slopes appeared stable with vegetative <br />cover. Hawthorne trees have been planted at several locations adjacent to the lake slopes. At the northeast <br />corner of Lake #1 a concrete head gate for the lake has been constructed. This head gate will need to be <br />included on the revised reclamation plan map to be submitted for the Technical Revision. <br />Part of the Technical Revision was a request from the Operator to leave a road that traverses the site. <br />Sections of the road that exist at the site are not displayed on the revised map submitted with the Technical <br />Revision. For example, a road is constructed to the east of Lake #2 between Lake #3. This road continues <br />around Lake #2 and connects with the road adjacent to the Gooding Dailey and Plumb Ditch. All sections of <br />the road intended to be left in-place after reclamation is complete will need to be displayed on the revised <br />reclamation plan map. <br />Also, part of the Technical Revision was a request to leave a barn structure in-place at the site. The map <br />submitted with the Technical Revision displays this barn in the wrong location. The barn is located on the <br />northwest corner of Lake #2. The correct location of the barn will need to be indicated on the reclamation <br />plan map. <br />Several stockpiles of "fill dirt" are located south of Lake #7 adjacent to the "house pad" identified on the map <br />submitted in the Technical Revision. Mrs. Johnson indicated Lafarge would like to leave these piles for the use <br />of the Landowner. There is no mention of these piles in the narrative of the Technical Revision; however, the <br />piles are indicated on the map. These piles cannot be left in place after reclamation, they will either need to <br />be graded out and seeded or removed from the property and the stockpile area reclaimed. <br />Lakes #5 and #6 are relatively small and are surrounded by dense wetland vegetation. Russian olive trees <br />have volunteered in several locations throughout the site. The majority of the Russian olive trees are <br />established along the pit slopes of Lake #7 and #8. A weed management plan is currently approved for this <br />site and will need to be implemented to control the spread of these trees. Mrs. Johnson indicated these trees <br />will be treated in the future.
