$500,000 - $600,000 for relocation of some of Northern Metals distribution $20.7 million for the increased cost of alternative transportation arrangements, (shifting from barge to truck). Unknown possible costs for the relocation of Marshall Concrete. Unknown possible costs related to the expected end of Aggregate Industries ability to extract and market lime (representing roughly 20% of their tonnage traveling through St. Anthony Falls).
Economic impact of lock closure Overall Minnesota economy % of Minnesota Economy impacted 84 jobs 3,000,000 jobs 0.0028% $5.3 million in wage income $9.3 million in value-added $14.4 million in economic output each year $166 billion in wage income $268 billion in value-added $494 billion in economic output each year 0.0032% 0.0035% 0.0035% In the context of the Minnesota economy, the impact would not appear to be significant. However, the impact to the specific businesses affected and the individuals who lose their jobs would be significant. Met Council Report, p. 3
The Minnesota DNR recently released a study entitled Water Recreation Economy at Risk from the Potential Spread of Asian Carp in Minnesota: Selected water resources connected to the Mississippi River north of the Twin Cities, May 2012. In light of the threat Asian carp pose to Minnesota s $4 billion boating and fishing economy, this paper provides limited estimates of the size of these economies for selected water resources north of the Twin Cities without defining how much of this at-risk economy would be impacted by Asian Carp. The $4 billion fishing economy is approximately 1% of Minnesota s overall economy Minnesota DNR, Water Recrea#on Economy at Risk from the Poten#al Spread of Asian Carp
Overall cost to businesses, plus economic impact of lock closure $49.7 million State bonding for light/bubble barrier at Lock #1 $19 million Federal cost of keeping locks open ($3.5 million annually) $98 million Value of Minnesota s fishing economy $122 billion
The U.S. Army Corps of Engineers operates the locks for the purpose of commercial navigation on public waterways; they are not authorized to manage Asian Carp An act of Congress is necessary to authorize lock closure Lock closure is controversial because of fears that it could set a precedent to close additional locks
Directs the Chief of Engineers to study the feasibility of temporarily and/or permanently closing the Upper St. Anthony Lock and Lock #1, modifying lock operations, or using an alternative technology barrier, to manage the threat of Asian Carp Requires the Chief to close such lock upon determining that a live adult Asian carp has been captured above Lock and Dam 2 (Hastings) or that a juvenile Asian carp has been captured above Lock and Dam 4 (Wabasha) Directs the Council on Environmental Quality to incorporate the Upper Mississippi River and tributaries, the Minnesota River, and the St. Croix River into the Asian Carp Control Strategy Framework of the Council (current focus is Great Lakes)
Requires the Director of the U.S. Fish and Wildlife Service (USFWS), in coordination with the Army Corps of Engineers, the National Park Service (NPS), and the U.S. Geological Survey (USGS), to lead a multiagency effort to slow the spread of Asian Carp in the Upper Mississippi and Ohio River basins and tributaries by providing high-level technical assistance, coordination, best practices, and support to state and local government strategies, to slow, and eventually eliminate, the threat posed by such carp.
