Storm Water Management Photo On May 10, 2007, the Tennessee Department of Transportation (TDOT) formally submitted the final Statewide Storm Water Management Plan (SSWMP) documents to the Tennessee Department of Environment and Conservation (TDEC).

This submittal represents the culmination of several years of cooperative effort between TDOT and TDEC to develop a comprehensive and state-of-the art plan to prevent erosion, control sediment, and manage storm water across Tennessee, with the overall goal of planning, designing, constructing and maintaining the state’s highways in such a way that minimizes the impacts of storm water runoff.

The plan grew out of the Amended Consent Order entered into by both agencies in March 2004. This Amended Consent Order was the result of problems with erosion prevention and sediment control that occurred on particular construction projects, but were indicative of problems that were occurring on other TDOT construction projects.

The SSWMP outlines the steps TDOT will take to implement erosion prevention and sediment control materials and practices for TDOT construction projects.

The draft SSWMP documents were made available for public review in January 2007 and a series of public meetings were held across the state in February 2007 to present information about the SSWMP and obtain public input.

The final documents incorporate comments and changes suggested by the public, TDEC and TDOT staff, as well as the World Wildlife Fund, Harpeth River Watershed Association, Tennessee Road Builders Association and other interested parties.

Several documents comprise the SSWMP, including:

  • Changes to the draft Environmental Division Procedures Manual:

    • Storm Water Management PhotoTDOT Environmental Division Mitigation Practices (PDF) – This new chapter of the Environmental Procedures Manual describes procedures and guidance the Ecology staff will use to identify and mitigate the impacts roadway projects have on streams, wetlands, and endangered species. It serves as a reference for TDOT Ecology staff in preparing project planning documentation and assessments for resource agencies. It also serves as a reference for mitigation methods and design.

    • TDOT Environmental Division Environmental Procedures Manual – Updates (PDF) – Revisions to the manual include the procedures that the Environmental Division should follow to incorporate environmental data into the project planning and development processes. The updates describe the process for identifying natural resource features, such as streams, springs, wetlands, and endangered or protected species, as well as the process for determining alternatives to minimize or avoid impacting sensitive areas.

  • Storm Water Management PhotoManual for Management of Storm Water Discharges Associated with Construction Activities (PDF) – This manual describes the current requirements of the TDEC General NPDES Permit for Discharges of Storm Water Associated with Construction Activities (Construction General Permit or CGP). Its focus is on field administration of TDOT construction projects to ensure that all phases of the work will comply with the requirements of the CGP. The manual discusses various materials and implementation methods for erosion prevention and sediment control (EPSC)

  • Procedures for Providing Offsite Waste and Borrow on TDOT Construction Projects (PDF) – This manual defines the process that TDOT construction personnel and contractors must follow to use offsite waste and borrow areas exclusively for TDOT projects. This includes all offsite areas that are supplied by either the prime contractor or a sub contractor. Implementing a consistent process across the state will help ensure that offsite waste and borrow areas can be properly permitted, constructed and stabilized.
     
  • Comprehensive Inspections Program (PDF) - TDOT has been performing QA/QC site assessments and EPSC inspections on TDOT construction projects. This
    document describes the Comprehensive Inspections Program (also called
    the Self-Monitoring Program in other products) that will be adopted and
    implemented by TDOT.
