This interim rule would make conforming amendments to the regulations of the Public Housing Operating Fund Program to reflect recent statutory amendments that allow for: The maximum term of an energy performance contract (EPC) between a public housing authority (PHA) and an entity other than HUD to be up to 20 years, and the extension of an existing EPC, without reprocurement, to a period of no more than 20 years, to allow additional energy conservation improvements. The increase in the maximum EPC term, which is currently limited to 12 years, is provided by statutory amendments and will enable longer payback periods for energy conservation measures.
