Montana’s MS4 Program: USEPA has notified many region 8 states that it intends to make its municipal separate storm sewer system (MS4) general permits more detailed to improve program effectiveness.  Seven cities and three counties within Montana have storm sewer systems which are regulated under the Montana Department of Environmental Quality’s (MDEQ) MS4 General Permit.  The state of Montana embarked on developing its new general permit more inline with EPA expectations at the beginning of 2015.  A working group of impacted stakeholders was created to address concerns with Montana’s MS4 program prior to the issuance of the next permit, which will become effective in January, 2017.  An MOU between the stakeholders and MDEQ created the framework for the permit discussions.  The stakeholders include the cities covered under the general permit, MDEQ, the US EPA, and several environmental organizations.  In addition, the affected counties, universities and federal facilities have participated.  This presentation will discuss the working group’s process, progress to date, and lessons learned in developing the new general permit.
