Chattanooga Coke Site Remediation
Manufacturing operations at the Chattanooga Coke Plant began in the early 1900’s and ceased in 1987. In the mid 1990’s, the abandoned structures on the 24.5-acre site were razed, but concrete pads, footings, foundations, USTs, unused sumps, an oil/water separator, and a storm/sanitary sewer remained onsite.
MeadWestvaco, owners of the property, retained DeNovo to perform remediation activities in order to prepare the site for re-development. DeNovo, in turn, engaged CTI to prepare a work plan and provide other engineering services in accordance with federal, state, and local requirements outlined in the Brownfield Consent Order entered into by MWV and the Tennessee Department of Environment and Conservation (TDEC), Division of Remediation (DoR).
CTI prepared the remedial action work plan, provided on-site observation of the work of the remediation contractor, and documented the implementation of said plan in a remedial action report which covered the following activities:
• Site preparation: Site security, erosion/sedmentation measures, traffic control.
• Identification, removal, and disposal of underground structures, their contents, piping, visible tarry waste, and coal-tar impacted soil (over 24,000 tons of “special waste” hauled via truck to landfill in an adjacent county, an additional 900 cubic yards of contaminated waste hauled by rail to Kentucky)
• Pumping, testing, disposal of groundwater and rainwater from excavated areas.
• Evaluation and selection of soils disposal facilities and transport
• Preparation of Remediation Action Work Plan
• Meetings with TDEC DoR
• Coordination of remediation scope with new site developer
• Re-creation of onsite removal grid (surveying)
• Onsite observation of remediation site work
• Preparation of daily inspection reports and monthly progress reports
• Necessary permits for site remediation (i.e., Storm Water Pollution Prevention Plan, approval of waste, etc.)
• Closeout documents
• Remedial Action Report (RAR) documenting closure per Work Plan
