A. The Lender must provide information in HEROS regarding compliance with NEPA, the laws and authorities listed at 24 CFR 50.4, and the HUD-specific requirements described herein, as applicable, as well as any issues that might affect the acceptability of the project, including any issues of compliance with state environmental laws. The HEROS submission and uploaded documentation constitutes the Environmental Report.
B. The HEROS submission must address each authority at the appropriate level based on the activity and level of environmental review. In cases where the MAP Guide has requirements that go beyond what is required in HEROS, Lenders and HUD staff must include MAP compliance on the appropriate HEROS screen.
