Outer Continental Shelf Wind Energy Database
EPA’s application of Outer Continental Shelf (OCS) Regulations to offshore wind energy generation is evolving. The submission and review of OCS applications for these projects has presented wind project developers and EPA with some unique questions. EPA has provided initial answers to many of these questions in the course of individual permitting actions and provided an opportunity for public comment.
The table below contains links to a selection of EPA-issued permits and other documents addressing topics that may be of general interest to wind energy developers applying for OCS permits under 40 CFR Part 55 and other stakeholders. This compilation of documents is provided solely as an informational tool for the public and is not intended to give any greater legal effect or significance to any referenced document than it has on its face. The referenced documents include fact sheets that provide EPA’s reasoning for proposed permit conditions and responses to public comments to support final permit decisions. EPA will consider each OCS air permit application on a case-by-case basis and take final action based on the record for each permit, following opportunity for public comment.
Documents may be sorted by topic, document name, issuing office, and date. Click the column header to switch between ascending and descending order. To sort by more than one column, hold down the Shift-key and select column(s) in the order of interest. To filter by keyword in the table, use the filter bar at the top of the table.
Please direct questions regarding these and other OCS permitting topics to the appropriate EPA Region.
