12. Post Construction Storm Water Management Minimum Water Quality Treatment Volume Channel Protection Criteria Handling storm water onsite using Low Impact Design (LID) techniques All projects over one acre must meet

13. Post-Construction Controls: Quality New Permit Post-Construction Controls: Quality Minimum treatment volume standard  One inch of runoff from entire site  Treatment designed for 80 percent removal of total suspended solids (TSS) or less than 80 milligrams per liter TSS

14. Post-Construction Controls: Quantity New Permit Post-Construction Controls: Quantity Channel Protection Standard  Maintain post-development runoff volume at or below existing levels.  Maintain post-development runoff peak rate at or below existing levels.  Based on 2-year, 24-hour storm.

15. Program Components Minimum Water Quality Treatment Volume Channel Protection Criteria Site Plan Requirements Operation and Maintenance Requirements Enforcement Mechanisms Recordkeeping Procedures Permittees shall ensure long-term Operation and Maintenance (O&M) plans for the water quality treatment and channel protection controls the permittee requires.

16. Some Flexibility Allowed for Post-Construction Controls  Allows alternative approaches (need MDNRE approval)  Treat the contiguous campus as one site  MDNRE has agreed to allow volume control at an alternative or regional site at a 1.2 multiplier  Establish an offset/bank program to meet standards

19. Alternative Approach Highlights for MSU  All projects will need to complete a storm water evaluation of the site including a cost estimate for required measures  Storm Water Review Committee will decide if regional approach is warranted for some or all storm water controls  Storm water fee will be assigned to each project that will include maintenance costs

20. Timeline  MSU’s Alternative Approach will be submitted to MDNRE by July 1, 2010 with implementation upon approval  Projects that start schematic design after July 1, 2010 will be required to follow the new procedure  All projects already in process should implement measures that are possible to meet the intent of interim compliance under the current permit

31. Eventually, all things merge into one, and a river runs through it. The river was cut by the world’s great flood and runs over rocks from the basement of time. On some of the rocks are timeless raindrops. Under the rocks are the words, and some of the words [will be ours]. —Norman Maclean
