Water Quality Program


CiticoCreekH2OshedsignThe Tennessee Department of Environment and Conservation (TDEC), Division of Water Resources issued the City of Chattanooga a National Pollutant Discharge Elimination System (NPDES) Permit for the discharge of stormwater from the municipal storm drain system (MS4). Stormwater from the City discharges directly to the Tennessee River and to major creeks that ultimately drain to the Tennessee River. 

Chattanooga's current NPDES Permit was issued November 12, 2010 (effective December 1, 2010) and will expire November 30, 2015.

The City's NPDES MS4 permit mandates the implementation of specific jurisdiction-wide management programs to control stormwater discharges to the "maximum extent practicable". Overall, the development and implementation of these programs have worked to reduce and minimize pollutants from entering streams from the MS4 drainage system. The NPDES Permit requires an annual system-wide report on the progress of Permit items. The Water Quality Program regurlarly maintains records of these Performance Measures.

 

In June 2012, the Water Quality Program implemented an Enforcement Response Plan, which serves to establish methods for controlling the introduction of pollutants into the regulated municipal separate storm sewer system (MS4). The objectives of the ERP are:

  • To regulate the contribution of pollutants into the regulated MS4 and community waters
  • To prohibit illicit connections and discharges to the regulated MS4 and community waters
  • To establish legal authority to carry out all inspection, surveillance and enforcement procedures necessary to ensure compliance with this document

 

 

Mission: To achieve 100% compliance with applicable Federal and State clean water laws and regulations, and to maintain and improve the condition and flow of the storm water infrastructure to address any existing or anticipated problem areas.
