Title: MRRRI Act
Policy area: Water Resources Development

Summary:
Mississippi River Restoration and Resilience Initiative Act or the MRRRI Act
This bill establishes the Mississippi River Restoration and Resilience Initiative to protect and restore the Mississippi River Corridor.
The Environmental Protection Agency (EPA) must establish the initiative and the Mississippi River National Program Office to carry out the initiative. The office must (1) coordinate agency actions to protect and restore the Mississippi River Corridor; (2) develop, implement, and update the initiative, actionable goals, and an action plan required by the bill; (3) make updates and information available on a public website; and (4) submit annual reports to Congress.
Additionally, the bill outlines the focus areas that each project carried out under the initiative must address, such as improving water quality and protecting wildlife habitat. The office may make grants to certain nonfederal entities to carry out eligible projects.
The bill directs the EPA to include the initiative as a separate budget line item in its annual budget submission.
Next, the bill directs the Department of the Interior to coordinate with the office to establish four Mississippi River Corridor research centers within the U.S. Geological Survey (USGS). These research centers must, among other duties, conduct scientific research on the focus areas of the initiative.
The bill also directs the USGS to host a science forum to share current science and identify data gaps related to the ecological health of the Mississippi River Corridor. The USGS must, within two years of the forum, develop a science plan for the initiative.

     To establish the Mississippi River Restoration and Resilience 
Initiative to carry out projects for the protection and restoration of 
        the Mississippi River Corridor, and for other purposes.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Mississippi River Restoration and 
Resilience Initiative Act'' or the ``MRRRI Act''.

SEC. 2. FINDINGS; PURPOSE.

    (a) Findings.--Congress finds the following:
            (1) The Mississippi River flows more than 2,300 miles from 
        its source at Lake Itasca through the center of the continental 
        United States to the Gulf of Mexico.
            (2) The main stem of the Mississippi River flows through 10 
        States that collectively are home to 55.4 million people as of 
        2019.
            (3) The Mississippi River provides drinking water to more 
        than 20 million people in 50 cities.
            (4) The Mississippi River drives a vibrant natural resource 
        and recreation-based economy that generates nearly $500 billion 
        in annual revenue and directly employs more than 1.5 million 
        people.
            (5) The Mississippi River and its 30 million acre 
        floodplain provide an ecological lifeline for all of North 
        America, supporting more than 780 species of fish and wildlife 
        and providing a vital migration corridor for 60 percent of all 
        North American birds and 40 percent of the migratory waterfowl 
        in the United States.
            (6) The Mississippi River serves as a major transportation 
        corridor for grain and cargo.
            (7) Congress has designated the Mississippi River System as 
        a nationally significant ecosystem and a nationally significant 
        navigation system and is the only inland river system to 
        receive both designations.
            (8) Despite its critical value to the United States, the 
        Mississippi River is in a severe state of ecological decline, 
        as documented by the United States Geological Survey, the Army 
        Corps of Engineers, and other Federal and State agencies.
            (9) Modifications to the Mississippi River have resulted in 
        the extensive loss of wetlands and complex river habitats 
        causing profound harm to the treasured fish and wildlife 
        resources in the United States and increasing flood risks to 
        communities.
            (10) Polluted runoff has drastically reduced water quality 
        and created a massive dead zone in the Gulf of Mexico.
            (11) Invasive aquatic species threaten the ecological 
        integrity of the Mississippi River and Gulf of Mexico, and the 
        fisheries and recreation that rely on a healthy ecosystem.
            (12) Ecological degradation of the Mississippi River has 
        resulted in--
                    (A) more flooding;
                    (B) less wildlife;
                    (C) fewer jobs;
                    (D) reduced recreational opportunities; and
                    (E) higher costs for keeping communities safe and 
                ensuring that communities have clean drinking water.
            (13) The consequences of ecological degradation have 
        disproportionately harmed rural communities, economically 
        disadvantaged communities, and communities of color.
            (14) Existing Federal programs lack sufficient 
        coordination, funding, and participation with States, Tribes, 
        local governments, and nongovernmental organizations to address 
        these ongoing challenges and reverse the decline of the 
        Mississippi River.
    (b) Purpose.--It is the purpose of this Act to establish the 
Mississippi River Restoration and Resilience Initiative to protect and 
restore the ecological health and resilience of the Mississippi River 
for current and succeeding generations of Americans and for the fish 
and wildlife that rely on the Mississippi River and its floodplain. The 
MRRRI is a nonregulatory initiative that will build upon existing 
efforts and provide funding for projects and activities to protect and 
restore the nationally significant resources of the Mississippi River 
by--
            (1) establishing the Mississippi River National Program 
        Office;
            (2) establishing the focus areas and identifying qualifying 
        activities for MRRRI programs and projects;
            (3) directing the development of actionable goals, an 
        action plan, and a science plan, and regular updates to such 
        plans, to guide the MRRRI;
            (4) establishing criteria for measuring the success of the 
        MRRRI in restoring the ecological health and resilience of the 
        Mississippi River;
            (5) requiring the Environmental Protection Agency to 
        coordinate and consult with Federal and non-Federal 
        stakeholders to implement the MRRRI; and
            (6) establishing the Mississippi River Corridor Research 
        Centers.
