(a) The purpose of the list of Type I actions in this section is to identify, for agencies, project sponsors and the public, those actions and projects that are more likely to require the preparation of an EIS than Unlisted actions. All agencies are subject to this Type I list.

1. (1) This Type I list is not exhaustive of those actions that an agency determines may have a significant adverse impact on the environment and requires the preparation of an EIS. However, the fact that an action or project has been listed as a Type I action carries with it the presumption that it is likely to have a significant adverse impact on the environment and may require an EIS. For all individual actions which are Type I or Unlisted, the determination of significance must be made by comparing the impacts which may be reasonably expected to result from the proposed action with the criteria listed in section 617.7(c) of this Part.
2. (2) Agencies may adopt their own lists of additional Type I actions, may adjust the thresholds to make them more inclusive, and may continue to use previously adopted lists of Type I actions to complement those contained in this section. Designation of a Type I action by one involved agency requires coordinated review by all involved agencies. An agency may not designate as Type I any action identified as Type II in section 617.5 of this Part.

(b) The following actions are Type I if they are to be directly undertaken, funded or approved by an agency:

1. (1) the adoption of a municipality's land use plan, the adoption by any agency of a comprehensive resource management plan or the initial adoption of a municipality's comprehensive zoning regulations;
2. (2) the adoption of changes in the allowable uses within any zoning district, affecting 25 or more acres of the district;
3. (3) the granting of a zoning change, at the request of an applicant, for an action that meets or exceeds one or more of the thresholds given elsewhere in this list;
4. (4) the acquisition, sale, lease, annexation or other transfer of 100 or more contiguous acres of land by a State or local agency;

5. (5) construction of new residential units that meet or exceed the following thresholds:

7. (7) any structure exceeding 100 feet above original ground level in a locality without any zoning regulation pertaining to height;
8. (8) any Unlisted action that includes a nonagricultural use occurring wholly or partially within an agricultural district (certified pursuant to Agriculture and Markets Law, article 25-AA, sections 303 and 304) and exceeds 25 percent of any threshold established in this section;
9. (9) any Unlisted action (unless the action is designed for the preservation of the facility or site), that exceeds 25 percent of any threshold established in this section, occurring wholly or partially within, or substantially contiguous to, any historic building, structure, facility, site or district or prehistoric site that is listed on the National Register of Historic Places (volume 36 of the Code of Federal Regulations, parts 60 and 63, which is incorporated by reference pursuant to section 617.17 of this Part), or that is listed on the State Register of Historic Places or that has been determined by the Commissioner of the Offie of Parks, Recreation and Historic Preservation to be eligible for listing on the State Register of Historic Places pursuant to sections 14.07 or 14.09 of the Parks, Recreation and Historic Preservation Law;
