Description

The Department of Housing and Urban Development (HUD) published a final rule revising its noise abatement and control regulations. Due to a drafting error, the codified text was not revised as intended and still references the Assistant Secretary for Community Planning and Development. This document corrects the text to align with HUD's original intent, replacing the reference with Program Assistant Secretary or their designee. The amendment affects 24 CFR part 51 and is effective August 20, 2026.
