N.Y. Comp. Codes R. & Regs. tit. 6 § 621.5
If a proposed project may require more than one department permit, or the preparation of an environmental impact statement the prospective applicant is encouraged to request a preapplication conference with appropriate department staff as a means of clarifying application content and procedures. This request should be made to the regional permit administrator at the appropriate location listed in section 621.19 of this Part. It should be made at the earliest possible stage of the applicant's project planning. The applicant must submit project plans and other relevant information to the department before the conference. At the conference, the proposed project will be informally discussed, permit requirements identified, and the applicant will be provided with guidance in the mechanics of the application and review process based on information provided by the applicant.
