EPA's October 20, 2021 Revised Draft Permit

On October 20, 2021, EPA reopened the public comment period on a revised draft permit for the proposed construction and operation of South Fork Wind, LLC's offshore windfarm on the Outer Continental Shelf (OCS). EPA reopened the public comment for an additional 47 days to request comment on a revision to the draft permit that removes the requirement to obtain emission offsets for construction emissions. The revised draft permit maintained control technology requirements for OCS sources engaged in construction activities, and the requirement in the permit to obtain offsets for operational emissions remained unchanged as well. EPA also took this opportunity to correct typographical errors and include provisions that were inadvertently omitted from the initial draft permit. Please refer to the supplemental fact sheet for the revised draft permit for a detailed analysis of the basis for the draft permit revision.
