This study provides an overview of potential impacts associated with port modifications that may be necessary to support offshore wind development along the U.S. East Coast. The study developed a set of criteria defining the port attributes necessary to support offshore wind development; identified and classified U.S. Atlantic Coast ports that could potentially service the offshore wind energy industry; characterized potential modifications needed to support the industry at these ports; and summarized potential impact producing factors, potential environmental and socioeconomic impacts, and potential mitigation measures associated with those port modification activities. This study provides the Bureau of Ocean Energy Management (BOEM) with documentation to a) support future National Environmental Policy Act (NEPA) reviews of offshore wind energy projects and b) aid in the project-specific assessment of potential environmental and socioeconomic impacts associated with the expansion and use of port facilities in support of Atlantic Outer Continental Shelf (OCS) offshore wind energy development projects. 499460 U.S. Department of the Interior, Bureau of Ocean Energy Management, Environmental Studies Program https://doi.org/10.13039/100012475 M0123F0061 10.67297/9A1F7B https://boem.gov/awardpages/100603
