(b) Manufacturing, Heavy: Any industrial use which requires buildings and open area for manufacturing, fabricating, processing, heavy repair, dismantling, testing, storage or disposal of raw materials, manufactured products or wastes, which is not injurious to health or safety of humans or animals. Typically, heavy manufacturing requires large sites for isolation and separation from residential and commercial development because of the potential spill over effect on surrounding areas, the use of buildings and open areas of the parcel for processing production, open storage and service areas, extensive services and facilities, and ready access to regional transportation. Normally, such uses generate some nuisances such as smoke, noise vibration, dust, glare, air pollution and water pollution, but not beyond the district boundary. Heavy manufacturing shall include primary metal industrial operations involving the use of blast furnaces, the rolling and finishing of ferrous and nonferrous metals, iron and steel foundries, primary and secondary smelting and refining facilities, metal plate and sheet fabricating facilities for metal plates and sheets, metal salvage and fabrication, and any other operations which shall be deemed to be of a similar nature. Heavy manufacturing shall also include mineral extraction; motor vehicles and related products, manufactured housing; household appliances manufacturing; gas manufacture; refining; manufacturing and/or processing of animals, or animal parts for food, fertilizer or other purposes including the tanning and production of leather goods and furs; the manufacture of food and meat products; paper and allied products; chemicals and allied products, including plastic materials, synthetic rubber and man-made fibers, soaps and detergents, paints and agricultural chemicals, petroleum refining and related industries, including production of paving and roofing materials, tire products, glass products and any other products of a similar nature.
