The Kentucky Division of Waste Management intends to approve a Groundwater Assessment Report received on June 4, 2012, from Southern Waste Services LLC in Logan County. This report fulfills a Kentucky Solid Waste regulatory requirement under 401 KAR 48:300 Section 8 that requires the landfill to submit a report to address specific groundwater monitoring results that exceed groundwater statistical limits in monitoring wells and/or springs at the landfill. The report describes the site hydrogeology and groundwater monitoring system, the assessment investigation, and the determination of the probable causes for the elevated constituents detected by the groundwater monitoring system at the facility.
The findings of the Groundwater Assessment Report AIN 20090001 indicate that the elevated monitoring parameters were detected by monitoring wells MW-16, MW-17, MW-18 and IW-7. The elevated monitoring parameters consist primarily of statistical increases for inorganic constituents and general water quality indicators including but not limited to chloride, sodium, iron, nickel, cobalt, specific conductance and total dissolved solids. No volatile organic chemicals were detected, and no maximum contaminant levels (MCLs) were exceeded. According to the Groundwater Assessment Report, the elevated monitoring parameters at the monitoring wells are a result of previous operational practices where contaminated surface water was impounded in an unlined excavation for a future waste cell that was located up-gradient of the monitoring wells. Precipitation and runoff contact with aluminum dross waste is the primary source of the observed sodium and chloride exceedances. This practice ended when the new Phase 7 lined waste placement cell was constructed. However, because the monitoring wells monitor slow-moving diffuse flow, groundwater moving through the area of the former impoundment continues to be impacted by residual contamination and detected in the downgradient monitoring wells. The facility will perform additional monitoring and reporting to determine if additional measures for abatement will be required.
A groundwater user survey, and monitoring of nearby ground water supply wells and springs, confirm that the groundwater degradation is localized by topographic and geologic factors and is not expected to impact local residential water supply wells or springs.
Southern Waste Services Landfill is located at 478 Coopertown Road and may be reached by traveling north from Russellville on U.S. Highway 431 approximately 3.3 miles to the intersection of U.S. Highway 431 and KY Highway 1040 (Coopertown Road). Continue along KY Highway 1040 approximately 0.5 mile to the landfill entrance. The landfill is located immediately east of KY Highway 1040.
The groundwater assessment report and related information can be reviewed at the Kentucky Division of Waste Management’s Frankfort office between 8:30 a.m. and 4 p.m. weekdays by appointment only. To make an appointment, submit a written request to Tina Fisher at least 72 hours prior to the desired review date. Requests can be faxed to 502-564-9232 or mailed to Ms. Fisher at the above address.
The Kentucky Division of Waste Management has scheduled a public meeting to be held on Thursday, Nov. 29, 2012, at 6 p.m. at the Old Logan County Courthouse located at 200 West 4th Street in Russellville. The public meeting, which is an opportunity to exchange information and answer questions concerning the Groundwater Assessment Report from Southern Waste Services LLC will run from 6 p.m. until 7 p.m. The public hearing, which is an opportunity for the public to make comments for the record, will begin at 7 p.m.
Any person who wishes to comment on the Groundwater Assessment Report may submit written comments at the meeting or submit in writing comments, by close of business on Dec. 6, 2012, to: Ronald D. Gruzesky, P.E., Division of Waste Management, 200 Fair Oaks Lane, Second Floor, Frankfort, KY 40601. Please reference Agency Interest No. 39028 and Activity No. AIN20090001 on any correspondence.
