Mulqueeney Ranch Wind Repowering Project
Document Type
NOP - Notice of Preparation of a Draft EIR
Document Description
Notice is hereby given that the County of Alameda (County) will be the Lead Agency and will prepare a Subsequent Environmental Impact Report (SEIR) for the Mulqueeney Ranch Wind Repowering Project (Project) pursuant to the California Environmental Quality Act (CEQA, 1970, as amended). The Project is an application for a Conditional Use Permit (CUP) to repower (i.e., redevelop) an estimated 518 previously existing wind energy turbine sites with up to 36 new turbines with nameplate production capacity rated between 2.2 and 4.2 megawatts (MW) each, that together will have a maximum production capacity of approximately 80 MW. Although the Project objective of 80 MW s of capacity could be nearly met with as few as 19 turbines with a rating of 4.2 MW each, or met with fewer turbines of different combinations of capacity ratings, the SEIR will evaluate up to 36 turbine sites in order to assess a worst-case condition of ground disturbance, visual effects, avian mortality, total rotor swept area and other potential impacts of 36 turbine sites, and a maximum Project capacity of 80 MW. Due to commercial considerations (e.g., turbine availability, financial decisions, etc.), final siting, _wind resource conditions and other site constraints, the applicant may reduce the number of turbine sites; however, the Project goal remains 80 MW of production, which will be the basis for the SEIR analysis. Micro-siting studies will also be conducted in parallel with preparation of the SEIR to assist in final siting decisions. See NOP for full details.
