The Homeless Emergency Assistance and Rapid Transition to Housing Act of 2009 (HEARTH Act), enacted into law on May 20, 2009, consolidates three of the separate homeless assistance programs administered by HUD under the McKinney-Vento Homeless Assistance Act into a single grant program, and revises the Emergency Shelter Grants program and renames it as the Emergency Solutions Grants (ESG) program. The HEARTH Act also codifies into law the Continuum of Care planning process, a longstanding part of HUD's application process to assist homeless persons by providing greater coordination in responding to their needs. This interim rule revises the regulations for the Emergency Shelter Grants program by establishing the regulations for the Emergency Solutions Grants program, which replaces the Emergency Shelter Grants program. The change in the program's name, from Emergency Shelter Grants to Emergency Solutions Grants, reflects the change in the program's focus from addressing the needs of homeless people in emergency or transitional shelters to assisting people to quickly regain stability in permanent housing after experiencing a housing crisis and/or homelessness.
