The Department of the Treasury (here) and the National Endowment for the Arts (here) both published final rules implementing revised FOIA regulations in today’s issue of the Federal Register. The Treasury rule, which is effective March 29, 2019, was intended to bring the agency into conformity with the OPEN Government Act of 2007 and the FOIA Improvement Act of 2016. No substantive changes were made to the proposed rule that was published for comments in October 2018. NEA’s regulations, which were revised for the same reasons, are effective immediately. No public comments were received by the agency.
