The Six Minimum control Measures

6 Minimum Control Measures Infographic.png

The Environmental Protection Agency's Stormwater Phase II Rule establishes an MS4 stormwater management program that is intended to improve the nation's waterways by reducing the quantity of pollutants that stormwater carries into storm sewer systems during rain events. 


Recognizing the value of approaching the new requirements regionally, the GLRC began meeting in 1998 and was officially formed under a Memorandum of Agreement in 2004.  The GLRC guides the implementation of the Phase II stormwater program by coordinating and cooperating on all program elements, known as the "six minimum control measures."
