This direct final rule contains several amendments to the regulations governing the HUBZone Program. The U.S. Small Business Administration (SBA) is making changes to its regulations to implement section 866 of the National Defense Authorization Act for Fiscal Year 2016 (2016 NDAA). Section 866 of the 2016 NDAA made the following changes to the HUBZone program: authorized Native Hawaiian Organizations to own HUBZone small business concerns; expanded the definition of "base closure area" under the HUBZone program; and authorized the inclusion of "qualified disaster areas" under the HUBZone program. This direct final rule would implement these changes in SBA's regulations.
