24 C.F.R. § 50.36 Updating of environmental reviews.
Title 24 - Housing and Urban Development
The environmental review must be re-evaluated and updated when the basis for the original environmental or compliance findings is affected by a major change requiring HUD approval in the nature, magnitude or extent of a project and the project is not yet complete. A change only in the amount of financing or mortgage insurance involved does not normally require the environmental review to be re-evaluated or updated.
