(b) Where no local waterfront revitalization program and harbor management plan exists which has been cooperatively prepared by all of the municipalities which border the shores of such a lake, no local law or ordinance adopted by one such municipality pursuant to a harbor management plan shall be approved without a finding by the secretary of state that the local law or ordinance is consistent as well with the management of the lake by, and interests of, the lake residents and its municipalities as a whole.

(c) Where an organization or entity has been created by statute to provide lakewide planning or regulation, such local laws or ordinances shall be consistent with the plans developed by such organization or entity pursuant to the procedures required in such statute. 4. No provision of this chapter shall be deemed to diminish the authority of any city, town or village pertaining to the regulation of harbors, surface waters and underwater lands granted by any other law, charter, patent or other instrument. Nor shall it be read to authorize local harbor management plans displacing conforming water-dependent businesses in existence on the effective date of this section. 5. Any conveyances of interests pursuant to subdivision seven of section seventy-five of the public lands law and any permits issued pursuant to subdivision one of section 15-0503 of the environmental conservation law shall be consistent, insofar as possible, with approved comprehensive harbor management plans adopted pursuant to this section.
