Intent To Prepare Draft Supplemental Environmental Impact Statement for the Allatoona Lake Water Supply Storage Reallocation Study and Updates to Weiss and Logan Martin Reservoir Project Water Control Manuals in the Alabama-Coosa-Tallapoosa River Basin
The U.S. Army Corps of Engineers (USACE), Mobile District, intends to prepare a Supplemental Environmental Impact Statement (SEIS) to evaluate potential changes to the Water Control Manuals (WCMs) for three reservoirs in the Alabama-Coosa-Tallapoosa (ACT) River Basin and to the Master WCM for the ACT River Basin. The USACE intends to conduct a water supply storage reallocation study to evaluate a March 30, 2018 request by Georgia and Cobb County-Marietta Water Authority (CCMWA) for increased water supply usage at Allatoona Lake and changed storage accounting methodology. The Draft SEIS will be prepared as an integrated document with the reallocation study. The reallocation study with the integrated Draft SEIS will address the water supply storage request and updated operating criteria and guidelines for managing the water storage and release actions of Federal water managers and will evaluate the associated environmental impacts of the proposed federal action, pursuant to the National Environmental Policy Act (NEPA). The USACE also intends to update the WCMs for the Alabama Power Company's Weiss and Logan Martin Reservoirs in the ACT River Basin.
