SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Mississippi River Navigation 
Sustainment Act''.

SEC. 2. FINDINGS.

    Congress finds that--
            (1) the Mississippi River is the largest, most famous river 
        in the United States and a vital natural resource;
            (2) the Mississippi River Basin is the third largest 
        watershed in the world, covering more than 1,000,000 square 
        miles and approximately 40 percent of the continental United 
        States;
            (3) the rivers, tributaries, and reservoirs that make up 
        the Mississippi River Basin operate naturally as a system and 
        any attempt to operate projects within the Mississippi River 
        Basin by mankind should take this fact into consideration;
            (4) the Mississippi River is the backbone of the inland 
        waterway system of the United States and a crucial artery for 
        the movement of goods;
            (5) each year millions of tons of commodities, including 
        grain, coal, petroleum, and chemicals, representing billions of 
        dollars are transported on the Mississippi River by barge;
            (6) the Mississippi River is home to some of the busiest 
        commercial ports in the United States, including the Port of 
        New Orleans and the Port of St. Louis;
            (7) safe and reliable navigation of the Mississippi River 
        is vital to the national economy;
            (8) extreme weather events pose challenges to navigation 
        and life along the Mississippi River and are likely to become 
        more severe and more frequent in the coming years, as evidenced 
        by the devastating floods along the Mississippi River in 2011 
        and the near historic low water levels seen on the same stretch 
        of the Mississippi River in the winter of 2012-2013;
            (9) the American Waterways Operators and the Waterways 
        Council, Incorporated have estimated that a disruption of 
        navigation on the Mississippi River due to low water levels 
        between December 2012 and January 2013 would have negatively 
        impacted 20,000 jobs and $7,000,000,000 in cargo;
            (10) the Regulating Works Program of the St. Louis District 
        of the Corps of Engineers is critical to maintaining navigation 
        on the middle Mississippi River during extreme weather events 
        and should receive continued Federal financial assistance and 
        support; and
            (11) the Federal Government, commercial users, and others 
        have a shared responsibility to take steps to maintain the 
        critical flow of goods on the Mississippi River during extreme 
        weather events.

Mississippi River Basin--
            (1) to improve the coordinated and comprehensive management 
        of water resource projects in the greater Mississippi River 
        Basin relating to extreme weather conditions; and
            (2) to evaluate the feasibility of any modifications to 
        those water resource projects and develop new water resource 
        projects to improve the reliability of navigation and more

    (b) Contents.--The study shall--
            (1) identify any Federal actions necessary to prevent and 
        mitigate the impacts of extreme weather, including changes to 
        authorized channel dimensions, operational procedures of locks 
        and dams, and reservoir management within the Mississippi River 
        Basin;
            (2) evaluate the effect on navigation and flood risk 
        management to the Mississippi River of all upstream rivers and 
        tributaries, especially the confluence of the Illinois River, 
        Missouri River, and Ohio River;
            (3) identify and make recommendations to remedy challenges 
        to the Corps of Engineers presented by extreme weather, 
        including river access, in carrying out its mission to maintain 
        safe, reliable navigation; and
            (4) identify and locate natural or other potential 
        impediments to maintaining navigation on the middle and lower 
        Mississippi River during periods of low water, including

            (2) to the maximum extent practicable, use data in 
        existence on the date of enactment of this Act; and
            (3) incorporate lessons learned and best practices 
        developed as a result of past extreme weather events, including 
        major floods and the successful effort to maintain navigation 
        during the near historic low water levels on the Mississippi 
        River during the winter of 2012-2013.
    (d) Cost-Sharing.--The Federal share of the cost of carrying out 
the study under this section shall be 100 percent.

        Guard is operating, may construct ingress and egress paths to 
        docks, loading facilities, fleeting areas, and other critical 
        locations outside of the authorized navigation channel on the 
        Mississippi River; and
            (2) operate and maintain, through dredging and construction 
        of river training structures, ingress and egress paths to 
        loading docks and fleeting areas outside of the authorized 
        navigation channel on the Mississippi River.
    (b) Mitigation.--The Secretary may mitigate through dredging any 
incidental impacts to loading or fleeting areas outside of the 
authorized navigation channel on the Mississippi River that result from 
operation and maintenance of the authorized channel.
