Great Lakes Shipping: Economic
Benefits
• The shipping industry employs 227,000 people in the U.S. and Canada and produces business revenue of $33.5 billion.
• Electrical utilities, steel mills, construction companies, mining companies, manufacturers and farmers all depend on the 164 million tons of cargo delivered by Great Lakes ships each year.
• Marine transportation on the System provides $3.6 billion in annual savings compared to the next best all land transportation alternative.
• 6,971 jobs are supported by the cargo moving via Toledo’s marine 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.

Ohio’s Position
• Ohio has long (25 years) consistent position on
this issue
• Toledo Harbor must be kept open
• Lake Erie must be restored & open lake disposal
is not acceptable
• Beneficial use and source reduction-best
• Strongly support cooperative partnerships
• Sustainable practices

• Introduction to the Project – The Ohio Lake Erie Commission was
awarded a GLRI grant to create a sediment management strategy/plan for the Toledo Harbor that identifies and addresses:
• recommended short-term (1-5 years) options
• recommended long-term (30 year) options
• funding needs/sources/mechanisms
• timelines for implementation of recommended approaches
– The Hull & Associates, Inc. Team was retained to assist in developing this plan

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

Single-Option Challenges
• Challenges of using only one alternative:
– Practicality/Logistics (low flexibility, seasonal limitations)
– Costs (high initial capital investment, balance between
capital and O&M)
– Location (large overall footprint)
– Optimization of alternative (compromise/tradeoff between
technical categories)
– Size (large structural requirements to control quantity)
• Both short-term and long-term plans will likely
consist of a combination of approaches due to the
challenges of single-option
