I <br /> PERMIT#:M-2001-022 <br /> INSPECTOR'S INITIALS:PSH <br /> INiPECTION DATE:December 10,2015 <br /> OBSERVATIONS <br /> The Green/Croissant Mine was inspected by Peter Hays with the Division of R lamation, Mining and Safety <br /> (Division/DRMS) as part of the Division's monitoring inspection program. Mrs. Stephanie Fancher with <br /> Loveland Ready Mix was present during the inspection. The Division previous! inspected the site on <br /> September 26, 2012. <br /> The Division currently holds a financial warranty in the amount of$350,400.04 which appeared adequate to <br /> perform reclamation at the site based on the observations from this inspection. <br /> The Operator stated the final augmentation plan for the site, Case No. 09CW1 5, has been approved by the <br /> Water Court. The Operator will need to submit proof of the final augmentatio plan approval by the Office of <br /> State Engineer (SEO)to the Division prior to any future full release request co sideration by the Division. <br /> The site was active during the inspection. The concrete batch plant located in he northwest corner of the site <br /> was operational and mining was occurring in Cell 4. The mined material is con eyed along the southern edge <br /> of the mining Cells 1-3 to the processing plant. Mining activity is complete in ells 1, 2 and 3. Cell 1 is used as <br /> a source for wash water for processing activities. Cell 2 is divided into 3 sectio s. The western portion of Cell <br /> 2 is completely backfilled and is used for the recycled concrete operation and ecycled concrete stockpile <br /> storage. The middle portion of Cell 2 is being backfilled with wash fines. The p ninsula of material between <br /> the middle and eastern portions of Cell 2 will be mined before the eastern po ion of Cell 3 is backfilled with <br /> wash fines. The eastern portion of Cell 2 was used as a settling pond with a p mp located in the northeastern <br /> corner of the pond. The slopes for all three cells appeared to be 2H:1V, which s steeper than the approved <br /> 3H:1V final slopes. Stormwater berms have been constructed around the perimeter of the cells and <br /> vegetation consisted of annual weeds. No erosion features were observed in the cells. <br /> The approved reclamation plan for the site states Cell 1 and the western part of Cell 2 will be backfilled with <br /> overburden and processing fines to create a potential 10 acre commercial/rets it development and reclaimed <br /> wetlands. The eastern part of Cell 2, Cell 3 and Cell 4 are planned to be reclaimed to wildlife ponds. The <br /> Operator stated during this and the last inspection the final reclamation plan fix-the site has changed. The <br /> current plan is to leave Cell 1 as an open water pond, backfill most of Cell 2 with the exception of the eastern <br /> portion and the eastern half of Cell 3 will not be mined due to the pipeline located in the area. The Operator <br /> will be required to submit a technical revision, per Rule 1.9,to update the approved Reclamation Plan. <br /> The mining excavation in Cell 4 is ongoing. The Division estimates approximat ly 75%of the cell had been <br /> disturbed at the time of the inspection with only the western portion of the ce I remaining undisturbed. <br /> Mining activities are progressing to the west. Dewatering trenches and pump were observed during the <br /> inspection. Overburden and topsoil was stockpiled adjacent to the excavation The southeastern corner of <br /> the Cell has been regraded to the required 3H:1V slope. The flood damage repair from the 2013 flood along <br /> the northern portion of Cell 4 is ongoing. Portions of the flood damaged vegetation is reestablishing. <br /> Additional revegetation work will be required to complete the restoration of the damaged area. <br /> The Operator stated they are in the process of rezoning the northern portion cif the mine site owned by <br /> Loveland Ready Mix to industrial/commercial with Weld County. The rezoning would allow the Operator to <br /> operate the concrete batch plant at the current location long term. Materialould be imported to the site <br /> from other mine sites once the mining reserve is exhausted at the site. The ch nge in post-mining land use <br /> Page 2 of 8 <br /> 1 <br />
