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

Sand Hill Wind, LLC, an affiliate of sPower (also known as Sustainable Power Group, an AES and AIMCo company), 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 1516 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 the County later determined that a Subsequent Environmental Impact Report (SEIR) is an appropriate means of complying with its obligations under CEQA. Links to the Draft SEIR, Notice of Preparation, Notice of Completion and Notice of Availability and other supporting documents, including the EA and Checklist, together with technical appendices, are available at the links below.

Links to Micro-Siting Studies carried out by wildlife biologists and researchers Dr. Shawn Smallwood and Estep Environmental Consultants are also provided. A hearing is scheduled to take comment on the Draft SEIR on September 12, 2019 as described in the Notice of Availability. Comments were previously scheduled to be received on the Draft SEIR through September 23, 2019, and will now be accepted through October 4, 2019. A Final SEIR will then be prepared with responses to comments received in advance of a hearing to consider certifcation of the SEIR and action on the Conditional Use Permit application, tentatively scheduled for November 14, 2019. (Note that the previously circulated Notice of Public Hearing which indicated a tentative final hearing date of October 24, 2019 should be updated accordingly to November 14, 2019. Formal notice of such hearing and Final Subsequent EIR documents will be posted on this page when they are available.)
