PERMIT#:M-1983-175 <br /> INSPECTOR'S INITIALS: CMG <br /> INSPECTION DATE: September 5,2024 <br /> stated they did not, to his knowledge, have a Certificate of Designation from the County or approval from the <br /> Colorado Department of Public Health and the Environment to legally dispose of solid waste and/or non-inert <br /> material on-site. <br /> The site contains several ponds with exposed groundwater. The DRMS observed a drum within one of the <br /> reclamation ponds (see Photo 7). Heavy corrosion and oxidation of the drum was observed. Due to the <br /> corrosive nature of the drums, rebar and metal material, as well as the other debris mixed in with the <br /> backfilled material and the contact with groundwater, negative impacts to the groundwater system are likely. <br /> A significant noxious weed infestation has occurred at the site. Noxious weed species observed were Tamarisk, <br /> Knapweed, Salt cedar, Canda thistle, and Russian olive (see Photos 9-12). These species were observed <br /> throughout the site, often in thick patches. In accordance with Rule 3.1.10(6) of the Construction Materials <br /> Rules and Regulations governing weed control, the DRMS will require the Operator to develop a weed control <br /> plan to be employed to control the current infestation and prevent the spread of weeds to the surrounding <br /> area. <br /> The Division currently holds a reclamation bond in the amount of$746,167.40 for this operation. The Division <br /> has estimated the reclamation liability at the site, based on what is currently disturbed and the cost to remove <br /> and dispose of the un-approved waste backfilled into the open groundwater pit. This liability is found to be <br /> $1,936,147.00. A copy of the reclamation cost estimate is enclosed. This is an increase of$1,189,979.60 from <br /> the bond currently held. The Operator will have 14 days (October 22, 2024), from the issuance of this report to <br /> submit any questions regarding the updated cost estimate. If no questions are received, the Division may issue <br /> a Surety Increase notice for the difference. The Operator will have 60 days from the date of the notice to <br /> submit and obtain acceptance of the increase in financial warranty from the Division in accordance with Rule <br /> 4.2.1(2) <br /> This concludes the DRMS's inspection report; a subset of photographs was taken during the time of the <br /> inspection are included below.
