SEC. 7. HYPOXIA OR HARMFUL ALGAL BLOOM OF NATIONAL SIGNIFICANCE.

    (a) Relief.--
            (1) In general.--Upon a determination under subsection (b) 
        that there is an event of national significance, the 
        appropriate Federal official is authorized to make sums 
        available to the affected State or local government for the 
        purposes of assessing and mitigating the detrimental 
        environmental, economic, subsistence use, and public health 
        effects of the event of national significance.
            (2) Federal share.--The Federal share of the cost of any 
        activity carried out under this subsection for the purposes 
        described in paragraph (1) may not exceed 50 percent of the 
        cost of that activity.
            (3) Donations.--Notwithstanding any other provision of law, 
        an appropriate Federal official may accept donations of funds, 
        services, facilities, materials, or equipment that the 
        appropriate Federal official considers necessary for the 
        purposes described in paragraph (1). Any funds donated to an 
        appropriate Federal official under this paragraph may be 
        expended without further appropriation and without fiscal year 
        limitation.
    (b) Determinations.--
            (1) In general.--At the discretion of an appropriate 
        Federal official, or at the request of the Governor of an 
        affected State, an appropriate Federal official shall determine 
        whether a hypoxia or harmful algal bloom event is an event of 
        national significance.
            (2) Considerations.--In making a determination under 
        paragraph (1), the appropriate Federal official shall consider 
        the toxicity of the harmful algal bloom, the severity of the 
        hypoxia, its potential to spread, the economic impact, the 
        relative size in relation to the past 5 occurrences of harmful 
        algal blooms or hypoxia events that occur on a recurrent or 
        annual basis, and the geographic scope, including the potential 
        to affect several municipalities, to affect more than 1 State, 
        or to cross an international boundary.
    (c) Definitions.--In this section:
            (1) Appropriate federal official.--The term ``appropriate 
        Federal official'' means--
                    (A) in the case of a marine or coastal hypoxia or 
                harmful algal bloom event, the Under Secretary of 
                Commerce for Oceans and Atmosphere; and
                    (B) in the case of a freshwater hypoxia or harmful 
                algal bloom event, the Administrator of the 
                Environmental Protection Agency.
            (2) Event of national significance.--The term ``event of 
        national significance'' means a hypoxia or harmful algal bloom 
        event that has had or will likely have a significant 
        detrimental environmental, economic, subsistence use, or public 
        health impact on an affected State.
            (3) Hypoxia or harmful algal bloom event.--The term 
        ``hypoxia or harmful algal bloom event'' means the occurrence 
        of hypoxia or a harmful algal bloom as a result of a natural, 
        anthropogenic, or undetermined cause.

SEC. 8. AUTHORIZATION OF APPROPRIATIONS.

    Section 609(a) (33 U.S.C. 4009(a)) is amended by inserting ``, and 
$22,000,000 for each of fiscal years 2019 through 2023'' before the 
period at the end.
Output: Harmful Algal Bloom and Hypoxia Research and Control Amendments Act of 2017 This bill amends the Harmful Algal Bloom and Hypoxia Research and Control Act of 1998 to reauthorize for FY2019-FY2023 the national harmful algal bloom and hypoxia program and the action strategy of the Inter-Agency Task Force on Harmful Algal Blooms and Hypoxia. (Hypoxia is a deficiency of oxygen.) The task force must include a representative from the U.S. Army Corps of Engineers. Each required scientific assessment of harmful algal blooms in coastal waters must examine freshwater harmful algal blooms that originate in freshwater lakes or rivers and migrate to coastal waters.  In administering the program, the National Oceanic and Atmospheric Administration (NOAA) must provide: (1) grants for accelerating the utilization of effective methods of intervention and mitigation to reduce the frequency, severity, and impacts of harmful algal bloom and hypoxia events; and (2) technical assistance to regional state, tribal, and local governments with respect to harmful algal blooms and hypoxia events. NOAA must use cost effective methods in carrying out the Act and develop contingency plans for the long-term monitoring of hypoxia. Federal officials may determine whether a harmful algal bloom or hypoxia event is an event of national significance and give funding to the affected state or local government for assessing and mitigating the detrimental environmental, economic, subsistence use, and public health effects of an event of national significance.
