NPDES Stormwater Program

The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates point source discharges from three potential sources: Municipal Separate Storm Sewer Systems (MS4s), construction activities and industrial activities. The NPDES Stormwater Program in Tallahassee is responsible for the development, administration and compliance of rules and policy to minimize and prevent pollutants in stormwater discharges. Operators of these sources may be required to obtain an NPDES permit before they can discharge stormwater.

Stormwater runoff is generated from rain events that flow over land or impervious surfaces, such as paved streets, parking lots and building rooftops, and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams and lakes. To protect these resources, municipalities, construction and industries activities, and others use stormwater controls, known as Best Management Practices (BMPs), to manage their runoff. The implementation of these practices, which include BMP design, performance and adaptive management requirements, prevent pollution by controlling it at its source.

Tallahassee Operation and Maintenance of Stormwater Management Facilities 

Operation & Maintenance Plan 

The Operation and Maintenance Plan outlines the specific operating procedures including routine maintenance consisting of mowing, cleaning of any structures or components of the conveyance system in which the runoff is carried and/or treated, and all other activities required to ensure that the facility performs as it was designed. It also includes estimates for the annual maintenance and any long-term maintenance that may be required, such as the replacement of a sand filter.


 Although the Growth Management Department will assist in every way possible to determine the cause(s) of a stormwater management system deficiency, it remains the responsibility of the owner, and owner’s designated agent, to inspect and maintain the facility and to immediately undertake any corrective measures necessary to ensure the facility continues to function properly. Constant attention to, and maintenance of, these facilities reduces the number of deficiencies determined by City inspectors. 

Renewals & Fees 

The Operating Permit is valid for three years from the date of its issuance, or subsequent renewal, and fees allow for the annual inspection of the facility by the Growth Management Department. Growth Management will notify the property owner, or designated agent of record, several months in advance of the renewal deadline. Changes in ownership, or designated agent, should be reported to Growth Management as soon as possible to ensure timely notification of an impending renewal.

Annual Inspections 

Facility inspections are performed, at least once annually, by the Growth Management Department. If deficiencies in maintenance or function are noted, the department will inform you in writing, of the required maintenance to restore proper function.
