MINE ID # OR PROSPECTING ID#: M-1977-348 PAGE: 2 INSPECTION DATE: 11-25-03 INSPECTOR'S INITIALS: ACS OBSERVATIONS Holcim began demolition of the cement plant during late summer of 2003. The Division of Minerals and Geology (DMG) approved disposal of demolition debris in one of the quarry pits through technical revision TR-004 to the mined land reclamation permit. The first lift of debris has been dumped into the quarry pit, and Gordon Benton of Holcim contacted DMG to do an inspection prior to covering the debris. The ongoing demolition and debris management operations were inspected first. The demolition contractor is Cherry Demolition out of Houston Texas. The following demolition equipment was observed in use: Numerous hydraulic excavators with various attachments including shears, hammers, and claw buckets. • A large crane (Link Belt) with wrecking ball. • Explosives. • Cutting torches. All rebar is cut off flush from concrete rubble. It was observed that the contractor is doing an excellent job of sorting and stockpiling the debris for its final disposition. Virtually all of the scrap metal, with the possible exception of rebar, will be recycled. Sorted scrap metal piles were observed throughout the demolition project area. Wood and other non-inert materials are prohibited from disposal in the quarry pit. These materials make up a small fraction of the total waste stream, and it was observed that wood and other materials had been sorted out and stockpiled separately for staging to an offsite landfill. By far the largest volume of debris being generated is concrete rubble. Essentially all of the concrete rubble will be dumped into the quarry pit. Several workers were observed torching exposed rebar off flush with the concrete rubble as required. The first lift of debris dumped into the quarry pit was inspected. The debris in the first lift is almost all-concrete rubble. Some rebar was observed and there was a worker torching off rebar at the time of the inspection. Disposal of rebar that has been cut from the concrete rubble is allowed in the quarry pit. However, the demolition contractor is working to find scrap yards that will recycle the rebar, and hopefully on site rebar disposal will be minimized. De minimus amounts of wood (about one armful) were observed in the first lift of debris, as were very small amounts of bare and painted metal. Based on this inspection DMG is satisfied that the debris in the first lift is inert and environmentally benign and Holcim may proceed with covering the material. Once demolition and debris disposal operations are completed in the quarry pit, Holcim will enter a second phase of demolition where the debris will be disposed in the concrete lined process water pond. This second debris disposal site will minimize haul distances for debris disposal. The asbestos investigation and abatement and the lead paint investigation commissioned by Holcim were discussed and certain relevant documents were provided to DMG. KEMWest, Inc. out of Denver conducted the lead paint
