In the event a public hearing is not required for final approval, and the application for final approval has been filed, together with all drawings, specifications, and other documents in support thereof, and as required by the resolution of tentative approval, the Village Board shall, within 30 days of such filing and after receipt of a report thereon by the Village Municipal Planning Board grant such plan final approval; provided, however, that, in the event the plan as submitted contains variations from the plan given tentative approval but remains in substantial compliance with the plan as submitted for tentative approval, the Village Board may, after a meeting with the landowner, refuse to grant final approval and shall, within 30 days from the filing of the application for final approval, so advise the landowner in writing of said refusal, setting forth in said notice the reasons why one or more of said variations are not in the public interest. In the event of said refusal the landowner may 1) file his application for final approval without the variations objected to by the Village Board on or before the last day of the time within which he was authorized by the resolution granting tentative approval to file for final approval, or within 30 days from the date he received notice of said refusal whichever date shall last occur; or 2) treat the refusal as a denial of final approval and so notify the Village Board.
