How are industrial facilities categorized in federal storm water regulations?

Industrial facilities are categorized in federal storm water regulations primarily by their Standard Industrial Classification (SIC) Code. This coding system assigns specific numerical codes to various types of economic activities, allowing for a systematic classification of industries based on their operational characteristics. The use of SIC Codes helps regulatory agencies determine which industries fall under the jurisdiction of the Clean Water Act and subsequently require permits for storm water discharges.

Understanding the SIC classifications is essential for both operators and regulatory bodies, as it facilitates compliance monitoring and enforcement of storm water regulations. Each code can signify different potential sources of pollution, enabling regulators to tailor requirements and inspections based on the unique risks associated with each industry. This systematic approach is vital for effective environmental management and protection of water quality.
