The mission of the TNSA is to assist local government entities in their efforts to comply with State and Federal clean water laws and Stormwater Regulations promulgated by the Environmental Protection Agency and the Tennessee Department of Environment and Conservation; and through such assistance, to protect and improve the quality of the waters of Tennessee.  This mission will be accomplished through TNSA members’ exchange of information and knowledge regarding the design, construction, maintenance, administration and operation of stormwater facilities.  The TNSA will promote the dissemination of information in stormwater control measures and the adoption of improved practices in stormwater administration.

The Tennessee Stormwater Association is a 501(c)3 non-profit organization organized under the laws of the State of Tennessee.  The Tennessee Stormwater Association (TNSA) was created June 10, 2008 upon the filing of the Charter with the Tennessee Secretary of State.  The TNSA is a state-wide organization operating within the boundaries of the State of Tennessee.

TNSA membership is composed of designated Municipal Separate Storm Sewer Systems (MS4s) including local governments (city and county), universities, military installations, and other entities such as TN Department of Transportation (TDOT).  Associate members include environmental advocacy groups, non-profits, Tennessee State, sub-state or federal government entities consultants.  Private sector membership is available to for-profit engineering, scientific and management firms  or other organizations with an interest in stormwater.

TNSA has been successful in working with the Tennessee Department of Environment and Conservation (TDEC) in becoming an active stake holder in the development of the new MS4 permit.

TNSA has also been successful in obtaining grants to help coordinate education between the various MS4/stormwater communities across the State and to help distribute information to those members.  The grant also funds the creation of localized education material and statewide education programs with some matching funds to assist our members in obtaining the greatest impact with our limited budgets.

TNSA worked with the TN Department of Transportation, the TN Department of Environment and Conservation, the Tourism Department and other vital partners in the development of the new Guide to Watersheds…a new map to be used as educational material to be distributed across the state at communities and Interstate Welcome Centers and Rest Areas.
