Maritime Administration


To improve facilities within, or outside of and directly related to operations of or an intermodal connection to, coastal seaports, inland river ports, and Great Lakes ports.

Applicant and/or Project Eligibility Requirements

Eligible applicants include a port authority, a commission or its subdivision or agent under existing authority, a State or political subdivision of a State or local government, a Tribal government, a public agency or publicly-chartered authority established by one or more States, a special purpose district with a transportation function, a multistate or multijurisdictional group of entities, or a lead entity described above jointly with a private entity or group of private entities.

Decarbonization Considerations

PIDP grants can improve port infrastructure, including intermodal connections, or reduce or eliminate pollutants and greenhouse gas emission. This program focuses on infrastructure enhancements that directly impact port operations. Consider projects that support freight and port vehicle fleet electrification, port resiliency with battery storage, and major efficiency retrofits to reduce the energy intensity of port operations. According to the 2023 NOFO, DOT seeks to fund projects that reduce emissions in the transportation sector, enable the deployment of clean energy including offshore wind, incorporate evidence-based climate resilience measures and features, reduce the lifecycle greenhouse gas emissions from the project materials, and avoid adverse environmental impacts, to air or water quality, wetlands, and endangered species, and address the disproportionate negative environmental impacts of transportation on disadvantaged communities.

Equity Considerations

PIDP program priorities have been updated to include a focus on improving racial equity and access to opportunity, mitigating or reducing the effects of climate change in addition to the goals of improving the safety, efficiency and reliability of the movement of goods. Consider clean energy and transportation upgrades that would reduce localized emissions and impact to neighboring communities.
