Water
discharges from industrial sources may contain pollutants that could effect
the quality of receiving waters. The Stormwater Quality Program establishes
specific requirements for discharges from industrial sources. Depending on
the type of industrial or commercial facility you operate, more than one
NPDES program may apply. Activities that take place at industrial facilities, such as material handling and storage, are often exposed to the weather. As runoff from rain or snowmelt comes into contact with these |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| materials, it picks up pollutants and transports them to nearby storm sewer systems, streams, or lakes. Stormwater pollution is a significant source of water quality problems for the City’s waters. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
In order to minimize the impact of stormwater discharges from industrial facilities, the Stormwater Quality program includes an industrial stormwater permitting component. Operators of industrial facilities included in one of the 11 categories of stormwater discharges associated with industrial activity that discharge or have the potential to discharge stormwater to a municipal separate storm sewer system (MS4) or directly to waters of the United States require authorization under a NPDES industrial stormwater permit. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The Stormwater Quality Program covers 33 industrial sectors that fall into one or more of the 11 categories of stormwater discharges associated with industrial activity described in 40 CFR 122.26(b)(14)(i)-(xi). The 33 sectors are listed in Table 1-1 (page 4) of the MSGP-2000 [PDF] and are defined by either the facility's Standard Industrial Classification (SIC) code or a general description of the facility’s industrial activities. The North American Industry Classification System (NAICS) will eventually replace the SIC system. The U.S. Census Bureau has a conversion table to bridge the two systems. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
Operators of industrial facilities or sites with activities included in one of these 11 categories must obtain coverage under an NPDES industrial stormwater permit, unless conditionally excluded. The list provided below describes the types of industrial activities within each category. |

Identified businesses located within Oklahoma City jurisdiction are audited on a regular basis. The intent of these audits is to reduce or eliminate the potential to pollute surface runoff at each site or facility. The Stormwater Quality Division screens these businesses and others with potential to cause pollution, for inclusion in an semi-annual environmental auditing program. |

The E.P.A.’s multi-Sector Permit identifies thirty-three industries with a high potential to contaminate surface runoff from their property. The list provided below are some of the industries required to get a NPDES permit. |
