GCSA Program Background


When the Phase II stormwater regulations were adopted by EPA in late 1999, INCOG member governments potentially affected by this new permit program requested INCOG’s assistance.  INCOG began a regional assistance program to address certain stormwater permit requirements, mainly dealing with public education and employee training, and to provide a variety of technical assistance to Green Country Stormwater Alliance (GCSA) members.

As permits began to be issued in 2006, the GCSA membership grew beyond just INCOG municipal membership to include additional cities in Northeast Oklahoma.  GCSA continues to have nearly half of all municipal permittees in Oklahoma as members.  Over the years, funding for INCOG’s GCSA program has shifted from EPA water quality grant funds to being wholly supported by annual stakeholder dues.  A list and map of GCSA members and their contact information can be found here.

Each municipal stormwater permittee must develop a Stormwater Management Program (SWMP) document that lists all of the permittee’s Best Management Practices (BMPs) that will be implemented to address the six EPA Minimum Control Measures (EPA’s categories of action items that must be implemented).  These are:

  1. Public education and outreach;
  2. Public participation and involvement;
  3. Illicit discharge detection and elimination;
  4. Construction site runoff control;
  5. Post-construction runoff control; and
  6. Pollution prevention & good housekeeping.

Each permittee must also submit an Annual Report to ODEQ that shows the accomplishments of the preceding year.  Each time the state’s general stormwater permit for small municipal systems (OKR04) is renewed (every 5 years), there are additional requirements placed upon municipal permittees and INCOG’s GCSA members.
