Thomas Date Chief, Environmental Division 81st Readiness Division Approved by: JAMELLE C. SHAWLEY Date Brigadier General, USAR Commanding General Executive Summary Environmental Assessment November 2020 Executive Summary This supplemental environmental assessment (SEA) was prepared for the U.S. Army Reserve (USAR) 81st Readiness Division (RD) to analyze the potential environmental and socioeconomic impacts associated with constructing and operating a 650-kilowatt photovoltaic (PV) array system at the Roosevelt Roads Army Reserve Center (ARC)/Armed Forces Reserve Center (AFRC) in Ceiba, Puerto Rico. This SEA tiers off of the Programmatic Environmental Assessment (PEA) for Construction and Operation of Solar Photovoltaic Renewable Energy Projects on Army Installations prepared by the U.S. Army. The Proposed Action is construction and operation of a 650-kilowatt PV solar array system at the Roosevelt Roads ARC/AFRC. The system will include direct-current/alternating-current inverters, a 13.2- kilovolt automatic distribution switch, connections to a microgrid, and battery components. The system design will meet National Electric Code, regulatory, and local utility requirements; meet energy production requirements; provide bi-directional metering with remote monitoring; and provide carbon dioxide emissions offsets. The Preferred Alternative and a No Action Alternative were evaluated for their potential direct, indirect, and cumulative impacts on the human environment. The USAR’s Preferred Alternative involves the construction and operation of the solar PV array on approximately 3 acres of previously developed land at the Roosevelt Roads ARC/AFRC, within the 100-year coastal flood hazard area. Under the No Action Alternative, the solar PV array would not be constructed. The No Action Alternative is required under the Council on Environmental Quality’s regulations implementing the National Environmental Policy Act. The No Action Alternative serves as a baseline, or benchmark, against which to compare a proposed action and alternatives. Among alternatives considered was one to construct the PV array system further west on the Roosevelt Roads ARC/AFRC, to be outside of the 100-year coastal flood hazard area. This alternative was eliminated from further consideration for the following reasons: (1) this alternative would require additional land clearing in heavily vegetated and overgrown areas; (2) the PV array would be on a slope, which would reduce the effectiveness of the array to capture solar radiation; and (3) this site is within a buffer area around the wind turbine and placing the PV array directly downhill from the wind turbine would create an avoidable risk if the wind turbine falls. The remainder of the Roosevelt Roads ARC/AFRC is developed or proposed to be transferred to the Roosevelt Roads Local Redevelopment Authority. The potential effects associated with implementing the Preferred Alternative on Roosevelt Roads ARC/AFRC would not result in any significant, adverse impacts. Anticipated adverse impacts would be local in context. The intensity of potential, adverse impacts is anticipated to be minor or negligible for all resources evaluated, with the exception of moderate impacts that are anticipated for hazardous materials and human health and safety. Section 4.0 of this SEA includes a summary of the conservation, protection, and mitigation measures which would be implemented to lessen impacts under the Preferred Alternative. This SEA concludes that neither the Preferred Alternative nor the No Action Alternative would constitute a major federal action with significant impacts on human health or the environment. Additionally, a finding of no significant impact for the Preferred Alternative should be issued to conclude the National Environmental Policy Act documentation process. A summary of potential impacts is in Table ES-1. ES-1 Executive Summary Environmental Assessment November 2020 Table ES-1.
