The MS4 annual meetings have been in Indiana since 2007.  The annual meeting was developed as a necessary tool to continue the growth of stormwater partnerships in Indiana.


It is not a new endeavor,  but a strong cohesion of permitted entities that have demonstrated that working together can result in great success.

The Indiana MS4 Partnership is a consortium of elected officials, municipal staff, and industry professionals brought together with mutual objectives of providing guidance and compliance tools for Indiana's NPDES MS4 Stormwater permittees.


The Partnership works with support from the Indiana Department of Environmental Management (IDEM) and the United States Environmental Protection Agency, Region 5 (EPA).  The Indiana MS4 Partnership will continue to provide regulatory guidance, technical assistance, educational opportunities and networking events to expand and grow information sharing statewide for elected officials, educators, inspectors, engineers, designers, and contractors. The Indiana MS4 Partnership is the result of the successful development and growth of the Indiana MS4 Annual Meeting.
