NYC Zoning Handbook:
Manufacturing Districts: M3

M3 districts are for heavy industries which generate noise, traffic and pollutants. Typical uses include chemical and power plants and foundries. The districts are usually located near the waterfront and buffered from residential areas. Even in M3 areas, certain uses with nuisance effects are required to conform to minimum performance standards. The two M3 districts differ only in parking requirements.
