c. Laboratory analysis of the groundwater monitoring conducted pursuant to this Paragraph III.A.S shall be performed and reported by a laboratory that holds NELAP/TNI (National Environmental Laboratary Accreditation Program/The NELAC Institute) or equivalent certification. The Parties acknowledge that the Illinois EPA has the existing legal authority to split samples with CLI and to conduct testing at Clinton Landfill3. 6. As of the date of entry of this Consent Order, CLI shall comply with all terms and conditions of Illinois EPA Landfill Permit No. 2005-070-LF, currently and as modified. 7. This Consent Order in no way affects the responsibilities of CLI to comply with any other federal, state or local laws or regulations, including but not limited to the Act. 8. The existing MGP Source Material within the CWU is currently covered with a minimum of 12 inches of clean soil as an"intermediate cover," as is required by the Illinois EPA regulations. In addition to and directly above that intermediate cover layer, CLI shall place an additional 12 inches of clean, select clayey soil of the same type that has proven to meet the Illinois EPA low permeability requirements for landfill cell compacted clay liner construction (low permeability compacted cohesive earth liner with hydraulic conductivity no greater than 1 x 10�� cm/sec). CLI or its contractor shall compact the additional 12 inches of said select clayey soil using the same equipment and methods utilized when constructing compacted clay liners for landfill cells. This relatively impermeable cap will minimize if not prevent altogether"new" water from coming into contact with the MGP Source Material. The existing leachate collection system beneath the MGP Source Material will ensure that any liquid that might be released from the MGP Source Material over time will be effectively collected and removed for proper management. 9
