Austin Peay State
Stormwater Illicit Discharge Detection and Elimination Policy

Issued:  March 25, 2017

Responsible Official:  Vice President for Finance and Administration

Responsible Office:  Physical Plant


Policy Statement

Austin Peay State University is classified as a Small Municipal Separate Storm Sewer System (MS4) by the Tennessee Department of Environment and Conservation and is subject to the state’s Small MS4 National Pollution Discharge Elimination System (NPDES) Permit. The university is responsible for screening, tracking, and developing policies and procedures addressing stormwater pollution.


This policy is intended to:
-Eliminate illicit discharges into the storm sewer system
-Comply with the requirements of APSU’s MS4 permit  


Storm Sewer

A storm sewer collects naturally occurring runoff water, delivering that runoff water to a river or other receptor without treatment.

Illicit Discharge

The unauthorized discharge of pollutants or non-stormwater materials to the storm drainage system via overland or direct dumping of materials into a catch basin or inlet. Generally, any discharges into a storm drain that is not composed entirely of stormwater. 

Examples of illicit discharges include the following:

  • Illegal connections to storm drainage system
  • Cleaning paint brushes in or around a catch basin
  • Dumping any non-stormwater into a storm drain
  • Soap and debris flowing to storm drain from cleaning operations


Discharges to the
Storm System

University employees, students, visitors, and contractors are prohibited from discharging any non-stormwater into stormwater systems on University property. This policy prohibits the dumping of chemicals, oil, antifreeze, wash water, paint, trash, leaves, and similar materials.  Personnel violating this policy shall be subject to appropriate disciplinary action as outlined in University policies and procedures.

Physical Plant shall monitor for illicit discharges into the stormwater system and shall take timely action to eliminate all such discharges.

All university construction contracts shall include language requiring compliance with this policy and with the University’s Non-traditional MS4 permit conditions. Facilities planning and projects and physical plant shall be responsible for monitoring compliance by construction contractors and taking appropriate action when non-compliances are detected.  Contract language will address penalties on contractors that violate this policy or applicable laws and regulations.

Facilities planning and projects and physical plant shall work to ensure that construction project designs include best management practices (BMPs), and all requirements for compliance with stormwater regulations, to minimize long-term impact of the project on stormwater quality.  Physical Plant shall be responsible for ensuring long-term operation and maintenance of permanent BMPs. 


All non-stormwater discharges to the MS4 are prohibited except the following:

Uncontaminated discharges from the following sources:

  • Water line flushing or other potable water sources;
  • Landscape irrigation or lawn watering with potable or water from a natural source
  • Rising groundwater
  • Diverted stream flows
  • Pumped groundwater
  • Foundation or footing drains
  • Crawl space pumps
  • Air conditioning condensate
  • Springs
  • Swimming Pools (if dechlorinated, less than 1ppm chlorine)
