Forsyth County Waste Management

Atlantic Coast Consulting, Inc. (ACC) has an experienced Environmental/Geotechnical Service Group, comprised of professional geologists specializing in applying the sciences of geology and hydrogeology in an efficient manner to meet and exceed our client’s needs. Our geologists are experts in soil and groundwater contamination assessment, monitoring program design, site characterizations, and facility permitting.

Management of extensive drilling programs is often a key component to ACC investigations. ACC geologists have extensive experience with direction and supervision of a variety of drilling techniques including hollow stem auger, double and triple tube rock coring, direct push, rotary air hammer, wash rotary, and roto-sonic. These investigations are often completed in general accordance with Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Resource Conservation and Recovery Act (RCRA), and Toxic Substance Control Act (TSCA) requirements, depending on the nature of the project.

Successful coordination and communication with the appropriate regulatory agency by ACC personnel ensures these projects remain in compliance with relevant requirements. ACC personnel have earned a mutually respectful relationship with the regulatory agencies through years of successful project completion.

Environmental/Geotechnical Services Featured Projects

Cumming, Georgia - In 2006, ACC was selected as Forsyth's on call solid waste engineering and environmental monitoring firm. The Forsyth County Hightower Road Landfill complex is a closed landfill that consists of pre- and Subtitle D municipal solid waste and construction and demolition material landfills Phases I and II began were originally permitted by EPD in 1986 under the authority of Forsyth County. Phase IV was permitted in 1993 as a Subtitle D lined MSW landfill. With the exception of the C&D portion of Phase II, the primary waste stream was municipal solid waste and other non-hazardous refuse. All four phases were capped in closure activities completed in 1999. Phase IV was capped in accordance with Subtitle D regulations with geocomposite clay liner and a geomembrane.

The other MSW phases contain clay and geomembrane infiltration layers that met the minimum infiltration rates required by EPD. Passive methane vents and trenches were installed at all phases (except Phase II C&D) during closure. Forsyth County is required to perform groundwater monitoring services for the closed landfill. The closed phases have passive gas extraction systems that are utilized to control impacts to groundwater. ACC provides groundwater and surface water monitoring, perimeter methane monitoring and post closure care inspections for the County at this facility. ACC has also prepared a revision to the Corrective Action Plan for this facility.
