(a) Type I. [See City Planning Rules 62 RCNY § 5-02(d).] Type I actions enumerated in § 617.12 of 6 NYCRR 617 are likely to, but will not necessarily, require the preparation of an EIS because they will in almost every instance significantly affect the environment. However, ministerial actions never require the preparation of an EIS except where such actions may directly affect a critical area or an historic resource enumerated in paragraphs (22) and (23), respectively, of subdivision (a) of § 617.12. In addition, for the purpose of defining paragraph (2) of said subdivision and section, the following thresholds shall apply:
(1) relating to public institutions:
(i) new correction or detention centers with an inmate capacity of at least 200 inmates;
(ii) new sanitation facilities, including:
(A) incinerators of at least 250 tons per day capacity;
(B) garages with a capacity of more than 50 vehicles;
(C) marine transfer stations;
(iii) new hospital or health related facilities containing at least 100,000 sq. ft. of floor area;
(iv) new schools with seating capacity of at least 1,500 seats;
(v) any new community or public facility not otherwise specified herein, containing at least 100,000 sq. ft. of floor area, or the expansion of an existing facility by more than 50 percent of size or capacity, where the total size of an expanded facility exceeds 100,000 sq. ft. of floor area.
(2) relating to major office centers: any new office structure which has a minimum of 200,000 sq. ft. of floor area and exceeds permitted floor area under existing zoning by more than 20 percent, or the expansion of an existing facility by more than 50 percent of floor area, where the total size of an expanded facility exceeds 240,000 sq. ft. of floor area.
(b) Type II.
(1) [See City Planning Rules 62 RCNY § 5-02(d).] Type II actions will never require the preparation of an EIS because they are determined not to have a significant effect on the environment, except where such actions may directly affect a critical area or an historic resource enumerated in paragraphs (22) and (23), respectively, of subdivision (a) of § 617.12 of 6 NYCRR 617.
