Storm Water Manual Policy & Procedures adopted 2-13-14
Technical Specification Manual Revision 2015

The Water Pollution Control Plant is owned and managed by the City of Seymour. The (WPC) department is charged with the responsibility of the daily operation and maintenance of the City of Seymour’s 8.7 million gallons/ day plant, the 125 miles of sanitary sewer, 25 miles of storm sewer collection systems, and 36 sanitary lift stations. The WPC must meet or exceed all Federal, State and Local specifications for effluent quality control, and provide all required reports and obtain all permits for operation of the facilities. The WPC also monitors 11 Industrial Users in the city to ensure compliance with city regulations. Funding for this utility comes from fees assessed each user.

Stormwater Program

Stormwater is water that originates during precipitation events. It may also be used to apply to water that originates with snowmelt that enters the stormwater system. Stormwater that does not soak into the ground becomes surface runoff, which either flows directly into surface waterways or is channeled into storm sewers, which eventually discharge to surface waters.

Stormwater is of concern for two main issues: one related to the volume and timing of runoff water (flood control and water supplies) and the other related to potential contaminants that the water is carrying, i.e. water pollution.  As the runoff flows over the land or impervious surfaces (paved streets, parking lots, and building rooftops), it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality if the runoff is discharged untreated.

In the United States, the Environmental Protection Agency (EPA) is charged with regulating stormwater pursuant to the Clean Water Act (CWA).  The goal of the CWA is to restore all “Waters of the United States” to their “fishable” and “swimmable” conditions.

The Indiana Department of Environmental Management’s Storm Water Quality Manual provides guidelines and specific storm water quality measures for controlling soil erosion; controlling and treating the nonpoint source pollution associated with sediment-laden runoff; and the management and treatment of pollutants associated with post-construction land uses. Adhering to these guidelines and properly applying appropriate storm water quality measures will help minimize the adverse impacts that land disturbance, construction activity, and development can have on soil and water resources, and ultimately, the cost of those impacts to society as a whole. In addition to a variety of storm water quality measures, the manual also discusses the philosophy and planning procedures critical to developing an effective storm water pollution prevention plan.

Managing the quantity and quality of stormwater is termed, “Stormwater Management.”  The term Best Management Practice (BMP) is often used to refer to both structural or engineered control devices and systems (e.g. retention ponds) to treat polluted stormwater, as well as operational or procedural practices. Stormwater management includes both technical and institutional aspects, including

  • manage stormwater to control flooding and erosion;
  • manage and control hazardous materials to prevent release of pollutants into the environment (source control);
  • plan and construct stormwater systems so contaminants are removed before they pollute surface waters or groundwater resources;
  • acquire and protect natural waterways where they still exist or can be rehabilitated;
  • build “soft” structures such as ponds, swales or wetlands or newer Green Infrastructure solutions to work with existing or “hard” drainage structures, such as pipes and concrete channels;
  • revise current stormwater regulations to address comprehensive stormwater needs;
  • develop funding approaches to stormwater programs potentially including stormwater user fees;
  • develop long-term asset management programs to repair and replace aging infrastructure;
  • enhance and enforce existing ordinances to make sure property owners consider the effects of stormwater before, during and after development of their land;
  • educate a community about how its actions affect water quality, and about what it can do to improve water quality; and
  • plan carefully to create solutions before problems become too great.
