Includes stormwater in the definition of sewage for purposes of certain water, sewer, and water and sewer authorities

This bill amends multiple sections of New York's public authorities law to explicitly include "stormwater" in the legal definition of "sewage" for water, sewer, and water and sewer authorities. It adds a new definition stating "stormwater" means water runoff that exceeds soil absorption capacity during rain or melt events. The change directly affects these public authorities by expanding their regulatory scope to cover stormwater under existing sewage-related rules. The bill does not create new programs or funding but clarifies how stormwater is legally treated in water management frameworks. (164 words)
