Executive Summary:

The following document is an outline for the City of Nixa, Missouri to use it as it enters the 2017-2021 permit term of the Phase II MS4s Program. The City intends to comply with the regulations as outlined by the State of Missouri General Permit No. MO-R040067 to the maximum extent practicable. This document is divided into a total of nine chapters. The first chapter begins with an outline of the plan coordination and overview of the program. As the chapters progress, the City's approach to meeting the six minimum control measures (MCM) is clearly outlined with the final chapter devoted to setting the framework for record keeping.

The City understands the importance of clean streams and rivers. One of the most important steps in ensuring clean streams and rivers is to improve the quality of stormwater runoff. As the City develops this program over the next permit term, it is the hope that measurable positive impacts will be seen by the City and its citizens.
