C) <br /> Transit Mix Concrete Co. <br /> RPM,Inc. <br /> (4) All backfilling and grading shall be completed as soon as feasible after <br /> the mining process. The Operator shall establish reasonable timetables consistent with <br /> good mining and reclamation procedures. <br /> Backfilling below the proposed capacity elevation with the delivered wash fines will be based on <br /> the average annual delivery rate to the pond. The anticipated life of the pond is 5 to 10 years. <br /> Once the pond is nearing its capacity, CMC/TMCC will make the decision to raise the elevation <br /> of the new pond or construct another pond in a different mined out area of the Daniels Sand Pit <br /> #2. If another new pond is constructed, reclamation will begin in this pond once the surface has <br /> dewatered sufficiently for equipment operation. <br /> (5) All refuse and acid-forming or toxic producing materials that have <br /> been mined shall be handled and disposed on in a manner that will control unsightliness <br /> and protect the drainage system from pollution. <br /> No such materials exist nor will such materials be placed in the waste fines disposal pond. <br /> (6) Any drill or auger holes that are part of the mining operation shall be <br /> plugged with non-combustible material, which shall prevent harmful or polluting <br /> discharge. Adits and shafts should be closed, and where practicable, backfilling and <br /> graded in a manner consistent with the post mine land use... <br /> There are no drill or auger holes which are part of the mining operation. However, Schlage Lock <br /> is responsible for a ground water remediation operation within and adjacent to the Daniels Sand <br /> Pit #2. There are apparently 3 wells which fall within the foot print of the area proposed to be <br /> impacted by pond operation and reclamation, SP-11A, SW-22A and SW-21. However, well SP- <br /> 11 is no longer in use as indicated in an email from Geosyntec, and also during a site visit by the <br /> contract site manager for the remediation project. In addition, we could not find it listed on the <br /> Division of Water Resources website. The other Schlage remediation wells appear to be outside <br /> the actual pond and will be protected during pond operation and reclamation by Transit Mix. The <br /> Schlage remediation facility, to include the above wells, was apparently installed after the <br /> Daniels Sand Pit #2 permit application approval. <br /> Further, Transit Mix need only give the remediation project management a 60 day notice if there <br /> is a need to mine through the wells. According to the Geosyntec representative during the site <br /> visit, the project is not ready to be terminated. The proposed impoundment is not expected to <br /> impact the on-going remediation operation. <br /> 5 <br />
