1. (1) For historic properties:

   1. (i) The consulting parties identified in accordance with 36 CFR part 800 must be consulted; and
   2. (ii) The Administration must receive written concurrence from the pertinent State Historic Preservation Officer (SHPO) or Tribal Historic Preservation Officer (THPO), and from the Advisory Council on Historic Preservation (ACHP) if participating in the consultation process, in a finding of “no adverse effect” or “no historic properties affected” in accordance with 36 CFR part 800. The Administration shall inform these officials of its intent to make a de minimis impact determination based on their concurrence in the finding of “no adverse effect” or “no historic properties affected.”
   3. (iii) Public notice and comment, beyond that required by 36 CFR part 800, is not required.

2. (2) For parks, recreation areas, and wildlife and waterfowl refuges:

   1. (i) Public notice and an opportunity for public review and comment concerning the effects on the protected activities, features, or attributes of the property must be provided. This requirement can be satisfied in conjunction with other public involvement procedures, such as a comment period provided on a NEPA document.
   2. (ii) The Administration shall inform the official(s) with jurisdiction of its intent to make a de minimis impact finding. Following an opportunity for public review and comment as described in paragraph (b)(2)(i) of this section, the official(s) with jurisdiction over the Section 4(f) resource must concur in writing that the project will not adversely affect the activities, features, or attributes that make the property eligible for Section 4(f) protection. This concurrence may be combined with other comments on the project provided by the official(s).
