DCO Energy, LLC (DCO), was the design-build contractor for the $200M, 50 MW AGE Biomass Renewable Energy Plant in Albany, Georgia, a project jointly developed by Constellation Energy (Exelon) and Proctor and Gamble Co., Inc. The original foundation design by a local consultant had resulted in a very conservative working pile resistance and a significant number of costly battered piles. Therefore, new steel H-pile foundations were proposed.
Due diligence performed by Geosyntec for a former lease on behalf of the property owner indicated several potential Recognized Environmental Conditions (RECs) on site that warranted further evaluation. Geosyntec completed due diligence activities with the goal of managing the site assessment and subsequent remediation of chlorinated pesticides within the guidance of the Georgia Hazardous Sites Response Act (HSRA) and Georgia Hazardous Site Inventory (HSI). Once a site is listed on the HSI, significant costs can be incurred for regulation-required delineation of contaminants of concern to background concentrations (non-detect in the case of pesticides). Geosyntec successfully managed the project to avoid a HSI listing.
