SEC. 6. CONSULTATION REQUIRED.

Section 102 of the Harmful Algal Bloom and Hypoxia Amendments Act
of 2004 (33 U.S.C. 4001a) is amended by striking ''the amendments made

Research and Control Act of 1998''.

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

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.
