Environmental/Geotechnical Services
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.

Environmental/Geotechnical Services Featured Projects
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.
Landfill Monitoring - Waste Management, Inc.
Various Georgia and South Carolina Facilities - ACC staff has provided solid waste services to Waste Management (WM) for over 10 years. Services have been provided to WM in Georgia, Tennessee, Alabama, Mississippi, Louisiana, South Carolina, and Puerto Rico. These services included hydrogeological / geotechnical investigations, preparation of permit applications and permit renewal applications, preparation of landfill D & O Plans, landfill gas system plans, end closure plans. ACC staff assisted WM with public meetings and with regulatory coordination. ACC staff prepared construction documents and specifications for construction of new Subtitle D landfill cells, groundwater monitoring reports, assessments of corrective measures, corrective action plans, closure of existing facilities, leachate pumping and storage facilities and transfer stations. ACC staff has provided construction administration and CQA services for the construction of landfill cells, closure caps, landfill gas systems, and other support facilities.
ACC executed a master agreement with WM in January 2006. ACC is currently providing groundwater monitoring services for five WM sites in South Carolina and two in Georgia. ACC completed the ACM for one site in Georgia and has completed CAPs for two other Georgia sites. ACC is also providing WM with other general solid waste services such as assisting with required updating of storm water pollution prevention plans (SWPPP) and spill prevention and control plans (SPCCP), to meet new NPDES permitting requirements.
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 which is located in Sandy Springs in the northern part of the County and the Merk-Miles Road Landfill which is located in the southern part of the County. Both landfills began operations prior to the adoption of Subtitle D regulations and therefore have minimal liner systems with no leachate collection. Active gas extraction systems have been installed at both landfills and must be operated and maintained to achieve the goals of the respective systems. 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. 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.
ACC was selected in 2006 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 and is also completing some final Corrective Action Plan items for the Merk-Miles Road facility. Although partially closed in 2009, the mulch processing area is currently being considered for development of a public soccer complex to serve the community of south Fulton County; ACC is assisting the county with this effort. ACC completed the design and construction for the installation of waste compactors at the Merk-Miles Road Landfill public convenience center in early 2010. The initial two compactors have reduced County expenses of operations by nearly 50%, primarily through reduced hauls to the landfill. Fulton County is currently planning a master plan redesign of the Merk-Miles Road Landfill convenience center to include expanded recycling activities, including paint. ACC is also exploring the use of the landfill gas generated at the Merk-Miles Road Landfill as a renewable energy source to operate the gas extraction system and possibly the convenience center compactors and scale house.
