Storm Water Management

Program Overview 

Polluted stormwater runoff is often transported to municipal stormwater drainage systems (MS4s) and ultimately discharged into local streams and rivers without treatment. EPA’s Storm Water Phase II Rule establishes an MS4 stormwater management program to improve the nation’s waterways by reducing the number of pollutants that stormwater picks and carries into stormwater systems during storm events. Common pollutants include oil and grease from roadways, pesticides from lawns, sediment from construction sites, and the careless discard of trash, such as cigarette butts, paper wrappers, and plastic bottles. When deposited into nearby waterways through MS4 discharges, these pollutants can impair the waterways, discouraging recreational use of the resource, contaminating drinking water supplies, and interfering with the habitat of fish, aquatic organisms, and other wildlife.

What are the requirements for the City of Nichols Hills?

 Operators of regulated small MS4s are required to:

  • Apply for NPDES permit coverage. This will shift program control to ODEQ.
  • Nichols Hills received our permit on August 15, 2005.
  • Develop a program that includes six minimum control measures.
  • Implement a program using “best management practices” (BMPs).
  • Develop measurable controls for the program.
  • Periodically evaluate the effectiveness of the program.
  • The ultimate objective is to protect our water supply.

What are the six minimum control measures?

The phase II rule outlines a small MS4 stormwater management program comprising six program elements that, when implemented in concert, are expected to significantly reduce pollutants discharged into receiving water bodies.

  1. Public Education and Outreach: Distribute educational materials and perform outreach to inform citizens about the impact of polluted stormwater runoff discharges on water quality.
  2. Public Participations/Involvement:  Providing opportunities for citizens to participate in program development and implementation, including organizing public hearings and encouraging citizen representation on a stormwater management panel.
  3. Illicit Discharge Detection and Elimination:  Develop and implement a plan to detect and eliminate illicit discharges to the storm sewer system (includes developing a system map and informing the community about hazards associated with illegal discharges and improper waste disposal.)
  4.  Construction Site Runoff Control:  Developing, implementing, and enforcing an erosion and sedimentation control program for construction activities that disturb 1 acre or more acres of land. Controls could include silt fencing or temporary stormwater detention ponds.
  5. Post-Construction Runoff Control:  Developing, implementing, and enforcing a program to address discharges of post-construction stormwater runoff from new development and re-development areas. Applicable controls could include preventative actions such as protecting sensitive areas (e.g., wetlands) or using structural BMPs such as grassed swales or porous concrete.
  6. Pollution Prevention/Good Housekeeping:  Developing and implementing a program to prevent or reduce pollutant runoff from municipal operations. The program must include municipal staff training on pollution prevention measures and techniques. This could consist of regular street sweeping, reductions in the use of pesticides and street salts or frequent catch-basin cleaning.

Allowable and Occasional Incidental discharges:

  1. Water line flushing
  2. Landscape irrigation
  3. Diverted stream flows
  4. Rising groundwaters
  5. Residential building wash water
  6. Uncontaminated pumped groundwater
  7. Uncontaminated groundwater infiltration
  8. Discharges from public water sources
  9. Foundation drains
  10. Springs
  11. Air conditioning condensate
  12. Water from crawl space pumps
  13. Footing drains
  14. Lawn watering
  15. Residential car washing
  16. De-chlorinated swimming pool discharges
  17. Street wash water
  18. Fire hydrant flushing
  19. Charity car washes
  20. Discharges from riparian areas and wetlands
  21. Discharges in compliance with OPDES or NPDES
  22. Discharges or flows from emergency firefighting

How do we fund and manage this unfunded mandate? 

  • Currently, the City of Nichols Hills is burdened with existing O&M funds. As the rule gets more stringent, we may have to approach the City Council for assistance.

The entire Storm Water Management Plan can be viewed at the Public Works office. Brochures and educational materials can be picked up at City Hall or the Public Works office. If you would like to participate or additional information, contact a member of the Public Works Staff  Or visit the EPA website at  www.epa.gov/npdes/stormwater.
