Environmental studies are an integral part of the Morgantown Energy Technology Center's (METC) fossil energy research program. In 1983, METC's environmental management program extended to cover the treatment and disposal of all wastewater generated at METC; the disposal of solid and hazardous waste generated by METC; and the monitoring of surface water, groundwater, and air quality in the surrounding area. METC's treatment system for sanitary wastes operated effectively throughout Calendar Year (CY) 1983. Industrial wastewater discharged by METC exceeded the permitted limits for cadmium and phenolics in CY 83. The source of low-level cadmium contamination is unknown at this time, but remains under investigation. In the last quarter of CY 83, discharge limits for phenolics were exceeded due to the development of leaks in process equipment of the gasification pilot plant, which is now being mothballed. This caused an overloading of METC's wastewater treatment system. METC is engaged in the construction of a new wastewater treatment facility for the correction of discharge problems. The facility is scheduled to be completed by late 1985. The monitoring of groundwaters in METC's industrial waste holding areas revealed that no contamination of groundwaters had occurred in CY 83. In 1983, all solid and hazardous wastes generated at METC were tested for EP toxicity and disposed of in an Environmental Protection Agency (EPA) approved secure landfill. Routine inspections revealed that landfill operators and hazardous waste disposal contractors for METC wastes were in compliance with the Resource Conservation and Recovery Act (RCRA) requirements. Air monitoring was performed at on- and off-site stations in CY 83 to satisfy the National Environmental Policy Act requirements. Data collected in CY 83 has not been reduced at this time; however, data collected from previous years indicates that METC project emissions have negligible impact on air quality. 8 references.
