ECI was contracted by AEP to provide a full range of EPC services for the 345 kV Sullivan Substation adjacent to the existing 765 station. The purpose of this project was to construct a new 345 kV station expansion, which was a result of the decommissioning of Breed Station. ECI was responsible for complete engineering design, material procurement, regulatory permitting, as well as comprehensive project, construction and material management. The purpose of this project was to construct the new 345 kV station which was the result of decommissioning an existing station approximately 1.5 miles to the southwest. The new 345 kV station was built immediately adjacent to the existing Sullivan 765 kV Station located in western Indiana.
ECI was also responsible for full regulatory compliance and permitting on the project site, including field wetland surveys and subsequent 404 permitting in cooperation with the Army Corps of Engineers and 401 permitting with the Indiana Department of Environmental Management. The overall physical design of the substation was amended to reduce impacts to adjacent wetland channels to the greatest degree feasible. As a result, the Army Corps of Engineers granted a nationwide permit with mitigation in accordance with Indiana State 401 Water Quality Certification. ECI also prepared a complete SWPPP in addition to the associated notification of Sullivan County and approval by the Indiana Department of Environmental Management. ECI, additionally prepared a full wetland mitigation plan to meet the 404/401 water quality certification requirements, and provided project management for additional resources surveys including Indiana Bat surveys prior to tree clearing conducted by Eco-Tech Consultants and cultural resource surveys with State Historical Preservation Office consultation by Cardno.
