§ 6-06 Determination of Significant Effect – Criteria.
RCNY § 6-06
(a)An action may have a significant effect on the environment if it can reasonably be expected to lead to one of the following consequences: (1) a substantial adverse change to ambient air or water quality or noise levels or in solid waste production, drainage, erosion or flooding; (2) the removal or destruction of large quantities of vegetation or fauna, the substantial interference with the movement of any resident or migratory fish or wildlife species, impacts on critical habitat areas, or the substantial affecting of a rare or endangered species of animal or plant or the habitat of such a species; (3) the encouraging or attracting of a large number of people to a place or places for more than a few days relative to the number of people who would come to such a place absent the action; (4) the creation of a material conflict with a community's existing plans or goals as officially approved or adopted; (5) the impairment of the character or quality of important historical, archeological, architectural or aesthetic resources (including the demolition or alteration of a structure which is eligible for inclusion in an official inventory of such resources), or of existing community or neighborhood character; (6) a major change in the use of either the quantity or type of energy; (7) the creation of a hazard to human health or safety; (8) a substantial change in the use or intensity of use of land or other natural resources or in their capacity to support existing uses, except where such a change has been included, referred to, or implicit in a broad "programmatic" EIS prepared pursuant to § 6-13 of this chapter.
(9)the creation of a material demand for other actions which would result in one of the above consequences; (10) changes in two or more elements of the environment, no one of which is substantial, but taken together result in a material change to the environment.
(b)(Reference to § 6-15 Type II list, deemed to be State Type II list of 6 NYCRR Part 617.13. See City Planning Rules 62 RCNY § 5-02(b)(2).) For the purpose of determining whether an action will cause one of the foregoing consequences, the action shall be deemed to include other contemporaneous or subsequent actions which are included in any long-range comprehensive integrated plan of which the action under consideration is a part, which are likely to be undertaken as a result thereof, or which are dependent thereon. The significance of a likely consequence (i.e. where it is material, substantial, large, important, etc.) should be assessed in connection with its setting, its probability of occurring, its duration, its irreversibility, its controllability, its geographic scope and its magnitude (i.e. degree of change or its absolute size). § 6-15 of this chapter refers to lists of actions which are likely to have a significant effect on the environment and contains lists of actions found not to have a significant effect on the environment.
