SEDIMENT ENTERING LAKE ERIE 2
IMPORTANCE OF THE TOLEDO HARBOR 15 Marine Terminals 700 vessel calls annually 12 million tons of cargo per year 6,971 jobs supported by cargo moving through terminals 2,521 jobs were directly generated by the maritime activity at the terminals with wages and salaries totaling over $109 million Direct business revenue received by the firms dependent upon the cargo handled at the Port totaled $381.3 million in 2010 Cargo and vessel activity generated $154.7 million in state and federal taxes in 2010 Largest land mass seaport on the Great Lakes 3
TOLEDO HARBOR DREDGING Federal Channel spans RM 7 to LM 18 (25 miles, 400-500 ft. width) Projected 1M CY Dredged Annually, includes federal and non-federal channels 30-year total of 30M CY

LAKE ERIE DREDGED MATERIAL PROGRAM Our Goal is to improve Lake Erie Water Quality by Addressing Potential Impacts from Dredged Material By July 2020, none of the material dredged from the eight Lake Erie federal navigation channels is disposed in the open waters of Lake Erie. Our policy objective is to increase use of material dredged from the eight Lake Erie federal navigation channels so its use creates an economic value and there isn t a need to dispose of it. Increase in-water use of dredged material to create/improve habitat, improve beach/near-shore nourishment Increase use of dredged material in the manufacture of marketable products Program Objectives Increase use of dredged material on brownfields and other land reclamation projects Remove barriers that inhibit use of dredged material Increase awareness of value of dredged material Increase awareness of potential uses of dredged material Increase awareness of availability of dredged material Content Credit: Ohio EPA
TOLEDO HARBOR SEDIMENT MANAGEMENT AND USE PLANNING The Ohio Lake Erie Commission received a $250,000 GLRI grant in 2010 to create a sediment management strategy for the Toledo Harbor Plan identified and addressed: Short-term (1-5 years) options Long-term (30 years) options Funding needs/sources/mechanisms Timelines for implementation Recommended next steps: Discuss project opportunities and associated legislation/funding needs with public officials, stakeholders and legislators Initiate pilot projects Pursue implementation of full-scale projects 7
CONCEPTUAL LOCATIONS OF SEDIMENT MANAGEMENT OPTIONS For illustrative purposes 8
AGRICULTURAL FIELD IMPROVEMENTS Use dredged material to raise the elevation of agricultural fields, thus, improving drainage and future productivity Pumping Dewatering Rate Consolidation Rate Agricultural Productivity Potential for Edge of Field Sediment pumped onto shore from the dredging operation center of gravity and subsequently pumped to final site via booster pump structures 9
ODNR EAST HARBOR STATE PARK UPLAND PLACEMENT PROJECT Hydraulic Dredge & Floating Pipeline (3,500 ft.) Pipeline (4,000 ft.) SR 163 Dredged Material Relocation Area (30 acres) Boundaries are approximate Not to Scale 10
ODNR EAST HARBOR STATE PARK UPLAND PLACEMENT PROJECT (CONTINUED) Material is pumped into one of four cells on the agricultural upland placement site One cell is filled before using adjacent cells 11

OHIO HEALTHY LAKE ERIE FUND FY2015-2016 State of Ohio capital budget bill provided $10 million for the Ohio Healthy Lake Erie Fund The Toledo-Lucas County Port Authority was allocated approximately $2.5 million through the Ohio Healthy Lake Erie Fund to design & construct: Demonstration Agriculture Field Improvement Project Edge of Field Areas Blended Soil Production Facility
GREAT LAKES DREDGED MATERIAL CENTER FOR INNOVATION PROJECT PARTNERS State of Ohio is funding this project Ohio Department of Natural Resources and Ohio EPA are co-administrators Toledo-Lucas County Port Authority is the grant recipient City of Toledo owns property that Port Authority is leasing U.S. Army Corps of Engineers is anticipated to provide dredge material to the site Hull Team is the competitively procured professional service provider
PROJECT GOALS Establish a model demonstration site that will further the cause of beneficial use of sediments locally and beyond Offer operational flexibility for short and long-term purposes Provide critical infrastructure now to facilitate use and future expansions/enhancements Provide for innovative edge of field research opportunities that will lead to future agricultural runoff impact reductions Provide for soil blending opportunities for long-term beneficial use of material
