The County of Alameda (County) prepared a Subsequent Environmental Impact Report (SEIR) to examine the environmental effects of the Sand Hill Wind Repowering Project (Project). The Project area is located within the Altamont Pass Wind Resource Area (APWRA) in eastern Alameda County.
Environmental review of the Project under CEQA began with the publication in September 2018 of an Environmental Analysis (EA) with supporting technical information intended to identify site specific Project effects pursuant to Section 15168 of the CEQA Guidelines, providing for use of a Program EIR with later activities. The County had previously approved three wind repowering projects that had been tiered under similar documentation. However, after receiving comments on the EA in advance of a public hearing to consider approving the Project on such basis, the County decided to prepare this SEIR based on its determination that the current Project proposes turbines with characteristics sufficiently distinct from those described in the PEIR and is proposed in the context of new information that together support the decision to prepare a subsequent EIR.
