This final rule amends HUD's Freedom of Information Act (FOIA) regulation to implement the FOIA Improvement Act of 2016. The FOIA Improvement Act enacted a range of procedural issues, including requirements that agencies establish a minimum of 90 days for requesters to file an administrative appeal, and codifies the foreseeable harm standard. In addition, this final rule revises a section of HUD's FOIA regulations to more accurately reflect statutory language.
