§ 23-05 Standards for Drainage Proposal Approval, Revision, and Revocation.
RCNY § 23-05
(a)Standard for approval of drainage proposals. The department shall approve drainage proposals or drainage proposal revisions only after the department has determined that such drainage proposals or drainage proposal revisions are complete and are in full compliance with all standards, requirements, and provisions of this rule and the department's most recent design criteria.
(b)Duration of approval. The department's approval of a drainage proposal or a drainage proposal revision shall be valid for a period of three years from the date of the department's written approval. The department may, upon written request made by an applicant prior to the expiration date of an approved drainage proposal, extend, without charge, the approval for a one-time sixty day period. An applicant shall be required to submit a new drainage proposal for review and approval if the approved drainage proposal expires before the applicant has obtained the department's approval of his or her private sewer or private drain plan.
(c)Status letter. An applicant may request the department to issue a letter to Department of Buildings regarding the status of the proposed private drain provided that the applicant has an approved drainage proposal and has posted all insurance, indemnities, performance and maintenance bonds, and security deposits required by this rule.
(d)Revisions. An approved drainage proposal may only be revised subject to the department's approval. The following non-exclusive list of changes to an approved drainage proposal render the approved drainage proposal null and void and require the submission of a drainage proposal revision with the applicable review fee: (1) a change to the type or kind of the proposed development; (2) a change to the point of sanitary or storm water discharge from the site; (3) the addition or deletion of property in the proposed development resulting in a corresponding change to the proposed private drain; (4) a change in the alignment of the proposed piping which does or may result in a change in the hydraulic design of the proposed private drain; or (5) a change in the location of a proposed private on-site detention basin facility.
(e)Revocation of drainage proposal approval. The department shall revoke its approval of a drainage proposal at any time if it determines that: (1) any of the information or documentation submitted in support of the drainage proposal is false, inaccurate, or misleading; (2) the approved drainage proposal fails to include adequate provisions for existing conditions that come to the attention of the department after it has approved a drainage proposal; or (3) the applicant has made any of the changes listed in paragraph (d) of this section without prior written approval of the department.
