Detailed guidance, including exemptions, can be found in the NSP Toolkits and NSP-related memos on HUD's Environment website. If NSP may affect a historic building or archeological site, the RE must consult with the State Historic Preservation Office (SHPO) and others to try to avoid, minimize or mitigate any adverse impacts to those properties. The conclusion of consultation may be documented in a letter signed by the SHPO or a Memorandum of Agreement. Sample letters are provided in the Toolkit. SHPO offices should be contacted early on as they are given up to 30 days to respond to each request for comment.
NSP activities in some states follow a Programmatic Agreement that outlines further streamlined procedures and exemptions.
