On Thursday, August 27th, an unprecedented coalition of 600+ public, private, and nonprofit-sector organizations representing 5 million Americans, sent an open letter to call on Congress to reject efforts underway through regulation, legislation, and executive action to dismantle one of America’s most successful bipartisan conservation and good-government laws. We asked specifically that Congress:
- Reject the Advisory Council on Historic Preservation’s proposed regulatory gutting of Section 106.
- Record your opposition during the Office of Information and Regulatory Affairs’ review and the public comment period, now underway.
- Reject statutory changes that weaken Section 106, whether advanced independently or as part of a
broader permitting package. - Defend Congress’s constitutional authority against executive efforts to narrow, circumvent, or evade the preservation laws Congress enacted.
- Seek genuine improvements to Section 106 based on facts and data to make review more valuable and efficient without trading away the rights, voices, and protections that make the process meaningful.
Today that coalition has surpassed 700 organizations. Read the full letter here.
For more information about the fight to Defend Section 106 and NHPA you can go here.
If your organization would like to sign onto this letter, please complete the form here
