## Abstract

The EPA is revising the outer continental shelf (OCS) air regulations in response to two remands from the U.S. Court of Appeals for the District of Columbia Circuit.

On May 20, 1996, EPA proposed revisions to the OCS regulations to provide for delegation to State and local agencies the authority to implement and enforce the OCS regulations beyond the 25-mile limit.

On May 20, 1996, EPA promulgated revisions to the OCS regulations to delete the special offset provisions and to req
