Monitoring & Assessments

Results and Reports

The City's stormwater program produces a variety of monitoring results and reports. They are categorized as follows:

  • Annual reports to the State Department of Environment and Conservation - uses a form provided by TDEC to be submitted by September 30 for the previous reporting year (July – June)
  • Illicit discharge screening - results of annual investigations to find non-stormwater discharges entering the city’s storm sewer system
  • Special studies - such as bacteria sampling and dye tracing
  • Status of water quality - the state’s online assessments and any local water quality reports
  • Stream monitoring - results of local visual assessments and chemical and biological sampling

Pollution Reduction Plans

The MS4 permit requires the city of Murfreesboro to develop pollution reduction plans.

3.1.1. Discharges into Waterbodies with EPA-Approved or Established TMDLs

The MS4 must implement stormwater pollutant reductions consistent with assumptions and requirements of any applicable wasteload allocation(s) in TMDLs established or approved by EPA. If an MS4 discharges into a water body with an approved or established TMDL, then the Stormwater Management Program must include BMPs specifically targeted to achieve the wasteload allocations prescribed by the TMDL. The SWMP must include a schedule for installation of such BMPs. A monitoring component to assess the effectiveness of the BMPs in achieving the wasteload allocations must also be included in the SWMP. Monitoring can entail a number of activities including but not limited to: outfall monitoring , in-stream monitoring or modeling. Monitoring requirements are further described in part 5 of this permit.

*Plans are actively being developed and updated.

Special Studies

Dye tracing studies are performed in order for city staff, planners and engineers better to understand the interconnections between surface waters and groundwater.

Other special studies will include watershed characterizations – including hydrologic modeling, stream determinations, and assessments.​
