New Environmental Analysis Approach for the 11th National OCS Program

For the 2nd analysis, BOEM is preparing an environmental analysis document that contains Outer Continental Shelf Lands Act requirements to inform the Secretary of the potential environmental impacts of the 11th National Program. This factsheet highlights the similarities and differences in this environmental analysis compared to the previous National OCS Program’s Programmatic Environmental Impact Statement under NEPA.

New Relative Environmental Sensitivity Analysis Model

The Marine Sensitivity Toolkit is an open-source, transparent interactive mapping system that integrates thousands of species distributions—from invertebrates and fish to seabirds, sea turtles, and marine mammals—to generate spatially explicit environmental vulnerability maps and scores across the US Exclusive Economic Zone, enabling BOEM to make informed, defensible decisions for oil & gas leasing and development.

By combining species sensitivity data, habitat distributions, and exposure assessments at multiple spatial scales—from regional planning down to individual lease blocks—this platform streamlines environmental review processes and supports efficient, science-based oil and gas operations.

The relative environmental sensitivity analysis that uses this new model is presented in Chapter 10 of the 1st Analysis and Proposal document.
