Sand Hill Wind Repowering Project - Application No. PLN2017-00201, Sand Hill Wind, LLC

Sand Hill Wind, LLC, an affiliate of sPower, has applied for a Conditional Use Permit (CUP) to repower an estimated 671 existing or previously existing wind energy turbine sites with up to 40 new turbines with a maximum production capacity of 144.5 megawatts (MW), using turbines rated between 2.3 and 3.8 MW (and potentially up to 4.0 MW) per turbine, on fifteen nearly contiguous parcels extending over approximately 2,600 acres within the eastern and Alameda County portion of the Altamont Pass Wind Resource Area (APWRA). The Project area is more specifically located along both the north and south sides of Altamont Pass Road, west of Grant Line Road, along both the east and west sides of Mountain House Road north of Grant Line Road, and on both sides of Bethany Reservoir, west of the Delta-Mendota Canal northwest of Mountain House Road, and southeast of the intersection of Christensen and Bruns Roads.

The Project is within the broad scope of the Altamont Pass Wind Resource Area (APWRA) Repowering Program that was the subject of a Program Environmental Impact Report (PEIR) certified by the East County Board of Zoning Adjustments on November 12, 2014 and is therefore being reviewed as a tiered project pursuant to Sections 15168(c) of the California Environmental Quality Act (CEQA) Guidelines. The County previously prepared and circulated for public review and comment an environmental analysis (EA) and a Checklist, intended to inform public agency decision-makers and the public generally of the significant environmental effects of the Project and identify possible ways to minimize such effects, particularly with respect to the extent to which the Project's impacts and mitigation measures had previously been identified in the PEIR. Based on comments on the EA from some public agencies and the Golden Gate Audubon Society, the County has determined that a Subsequent Environmental Impact Report (SEIR) is an appropriate means of complying with its obligations under CEQA. The Notice of Preparation for the SEIR, which provides more description of the Project, background information and advisement for receiving comments, was made public on January 3, 2019 and can be downloaded from a link below. In addition, the EA and Checklist, together with technical appendices, are available at the links below for reference purposes pending completion of the SEIR.

A preliminary hearing by the East County Board of Zoning Adjustments was held on September 27, 2018, to take public comment on the Project proposal and on the EA. The Board continued the matter to its next meeting, tentatively scheduled for October 11, 2018, for a decision on the CUP; however, since then the County has chosen to have the SEIR prepared. New hearings will be scheduled for consideration of the SEIR and the Project when the document becomes available.
