6. The Challenge of Ballast Treatment Technology Development IMO standard difficult to measure against IMO standard difficult to measure against No clear standard yet domestically No clear standard yet domestically Tests on board ships are difficult to control and replicate Tests on board ships are difficult to control and replicate Shore based tests require special test conditions Shore based tests require special test conditions –Large tanks –Specialized analyses –High flow rates –Various conditions Ballast Water Research

10. Accelerated Corrosion in the Duluth-Superior Harbor THE PROBLEM Advanced localized corrosion in submerged steel structures Evident on all steel structures in the working harbor area - up to 7 miles upstream from Aerial Lift Bridge Severity of corrosion is most severe in the upper 4 feet of submerged dock structure

14. Potential Causes Iron-oxidizing (Siderooxidans lithoautotrophicus) and iron-reducing (Rhodoferax ferrireducens) bacteria are present on corroding steel sheet pilings Accelerated Corrosion in the Duluth-Superior Harbor

15. Dredged Material Management

16. Advanced dredged material management planning must be conducted on a port or regional scale by a partnership that includes the Federal government, the port authorities, state and local governments, natural resource agencies, public interest groups, the maritime industry, and private citizens. National Dredging Policy Principles

17. Dredged material is a resource, and environmentally-sound beneficial use of dredged material for such projects as wetland creation, beach nourishment, and development projects must be encouraged.

18. Erie Pier Confined Disposal Facility (CDF)

19. Erie Pier Management Plan Sets management processes in place to facilitate a dredged material reuse program at Erie Pier Describes testing procedures and reuse guidelines from both MN & WI

20. Updating of the Dredged Material Management Plan (DMMP) DMMP must include 20 years of dredged material management strategies We are currently compiling potential projects and strategies for the Army Corps for Engineers to study further
