Phase II Stormwater Program

In 1972, the National Pollutant Discharge Elimination System (NPDES) program was established under the authority of the Clean Water Act. The NPDES permit requires that the town of Indian Trail develop regulations, ordinances, policies, and procedures to implement a Stormwater Program. Additionally, Indian Trail is required to maintain adequate funding, management, and staffing for the Stormwater Program.

The purpose of the Stormwater Management Plan is to reduce the discharge of pollutants from the municipal separate storm sewer system (MS4).
 

 

What is a Phase II Community?
The Phase II program extends permit coverage to communities with populations less than 100,000 and public entities that own or operate a municipal separate storm sewer system. Indian Trail has been a Phase II community since 2005.


What are the components of the Phase II program?
The NPDES Phase II permit requires the following components:

  1. Public Outreach and Education
    • Distribute educational materials to the community.
    • Conduct public outreach activities.
    • Raise public awareness on the causes and impacts of stormwater pollution.
    • Inform the public on steps they can take to reduce or prevent stormwater pollution.
       
  2. Public Involvement and Participation
    • Provide opportunities for the public, including major economic and ethnic groups, to participate in program development and implementation.
    • Comply with applicable state and local public notice requirements.
       
  3. Illicit Discharge Detection and Elimination
    • Detect and eliminate illicit discharges, including spills and illegal dumping.
    • Address significant contributors of pollutants to the MS4.
    • Implement appropriate enforcement procedures and actions.
    • Develop a storm sewer map showing all outfalls and waters receiving discharges.
    • Inform employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste.
       
  4. Construction Site Runoff Controls
    • Reduce pollutants in stormwater runoff from construction activities disturbing one or more acres of land surface and those activities less than one acre that are a larger common plan of development.
    • Provide procedures for public input, sanctions to ensure compliance, requirements for construction site operators to implement appropriate erosion and sediment control practices.
    • Establish requirements for construction site operators to control waste.
       
  5. Post-Construction Site Runoff Controls
    • Manage stormwater runoff from new development and redevelopment that drains to the MS4 and disturbs an acres or more of land surface, including projects less than an acre that are part of a larger common plan of development or sale.
    • Provide a mechanism to require long-term operation and maintenance of Best Management Practices (BMPs).
    • Ensure controls are in place to minimize water quality impacts.
       
  6. Pollution Prevention and Good Housekeeping for Municipal Operations
    • Prevent or reduce stormwater pollution from municipal operations and maintenance activities.
