Hightower Road Landfill - Forsyth County Board of Commissioners
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.

Morgan Falls Road Landfill & Merk-Miles Road Landfill Environmental Monitoring - Fulton County, Georgia
Fulton County, Georgia - Fulton County owns two closed MSW landfills; the Morgan Falls Road Landfill is located in Sandy Springs in the northern part of the County and the Merk-Miles Road Landfill is located in the southern part of the County. Both landfills were operated before the Subtitle D regulations were adopted and therefore have minimal liner systems with no leachate collection. Active gas extraction systems have been installed at both landfills. The Morgan Falls Road Landfill is also the site of a privately operated golf course open to the public. Merk-Miles Road Landfill is the site of one of the County's public convenience centers for County citizens to drop off waste destined for disposal off-site. Active gas extraction systems have been installed at both landfills and must be operated and maintained to achieve the goals of the respective systems. A portion of the Merk-Miles Road Landfill property was used by the County as a wood waste mulching/composting operation after closure of the landfill.
In 2006, ACC was selected as Fulton County's solid waste engineering and environmental monitoring firm. ACC provides groundwater and surface water monitoring, perimeter methane monitoring and post closure care inspections for the County at both closed landfills. ACC also operates and maintains the active gas extraction systems at both landfills. ACC is completing some final Corrective Action Plan items for the Merk-Miles Road facility. ACC is overseeing the closure of the mulch operation.
