Standard Industrial Classification (SIC) code — A system for classifying industries by a four-digit code. Established in the United States in 1937, it is used by government agencies to classify industries into categories. In the United States, the SIC code has been replaced by the six-digit North American Industry Classification System (NAICS code), which was released in 1997; however, some government departments and agencies still use the SIC codes.
No Exposure Certification (NOEC) — In the storm water rules, no exposure is defined as all industrial materials and activities that are protected to prevent exposure to rain, snow, snowmelt, and/or runoff. Industrial materials or activities include, but are not limited to, material handling equipment or activities, industrial machinery, raw materials, intermediate products, by-products, final products or waste products.
