Today marks the first official day of the Illinois Clean Marina Program, a voluntary plan that gives marina and boatyard personnel the tools they need to keep pollution out of rivers and lakes. And Chicago’s newest and largest marina has already pledged to become the first clean marina in the state. 

 
To earn clean marina status, 31st Street Harbor will implement a series of best management practices that make marina operations more efficient and environmentally friendly. The practices cover a broad range of topics from marina construction to sewage handling, and the majority of them are easy and affordable. Some of the activities in the program include conducting vessel maintenance without washing debris into water, scheduling construction to ensure that nearby habitats are protected, and other steps that help reduce environmental impacts. 
 
Marina managers that pledge to join the program will receive training from the Illinois Department of Natural Resources (IDNR) to help implement the program’s best management practices. In addition, Illinois-Indiana Sea Grant, IDNR, and the Chicago Park District are developing a Clean Marina Guidebook with how-to guidance for all program requirements. The guidebook will give important information on laws and permit programs related to marina activities, direct marina personnel to additional resources, and include clean boating tip sheets that can be distributed to boaters. The Illinois Clean Marina Guidebook will be available soon on the program website
 
Officials at the Park District expect 31st Street Harbor to complete the certification process later this month. Five additional marinas in the Chicago area are expected to join their ranks within the year. Marina managers interested in pledging to be a clean marina can contact IDNR’s Kim Kreiling at 312-814-6260 or kim.kreiling@illinois.gov to begin the certification process.
