(a) Prior to making Section 4(f) approvals under § 774.3(a), the Section 4(f) evaluation shall be provided for coordination and comment to the official(s) with jurisdiction over the Section 4(f) resource and to the Department of the Interior, and as appropriate to the Department of Agriculture and the Department of Housing and Urban Development. The Administration shall provide a minimum of 45 days for receipt of comments. If comments are not received within 15 days after the comment deadline, the Administration may assume a lack of objection and proceed with the action.
(b) Prior to making de minimis impact determinations under § 774.3(b), the following coordination shall be undertaken:
(1) For historic properties:
(i) The consulting parties identified in accordance with 36 CFR part 800 must be consulted; and
(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.”
(iii) Public notice and comment, beyond that required by 36 CFR part 800, is not required.
(2) For parks, recreation areas, and wildlife and waterfowl refuges:
(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.
(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).
(c) The application of a programmatic Section 4(f) evaluation to the use of a specific Section 4(f) property under § 774.3(d)(1) shall be coordinated as specified in the applicable programmatic Section 4(f) evaluation.
(d) When Federal encumbrances on Section 4(f) property are identified, coordination with the appropriate Federal agency is required to ascertain the agency's position on the proposed impact, as well as to determine if any other Federal requirements may apply to converting the Section 4(f) land to a different function. Any such requirements must be satisfied, independent of the Section 4(f) approval.
