The U.S. Senate has passed a bill sponsored by Ohio senators Sherrod Brown and Rob Portman that intends to improve the federal response to water pollution by amending the Harmful Algal Bloom and Hypoxia Research and Control Act of 1998. Senate Bill 1057 will now move on to the House of Representatives for debate.
What are harmful algal blooms and hypoxia?
The EPA defines harmful algal blooms as “overgrowths of algae in water,” some of which “produce dangerous toxins in fresh or marine water.” The toxins can be dangerous for humans and animals. One major contributor to algal blooms is an excess of nitrogen and phosphorus in the water. Hypoxiacan also be caused by too much nitrogen and phosphorus in the water. The EPA defines hypoxia as “low oxygen” in water. Hypoxia sometimes goes hand-in-hand with algal blooms, because as algae dies, it uses oxygen, which in turn removes oxygen from the water. Algal blooms and hypoxia have been a problem in Lake Erie and other parts of the country.
Background of the law
The Harmful Algal Bloom and Hypoxia Research and Control Act was passed in 1998 in response to harmful algal blooms and hypoxia along the coast of the United States. When passing the law, Congress cited scientists who said both problems were caused by “excessive nutrients.” Furthermore, Congress found that harmful algal blooms had caused animal deaths, health and safety threats, and “an estimated $1,000,000,000 in economic losses” in the previous decade.
The law established an interagency Task Force on Harmful Algal Blooms and Hypoxia (Task Force), which was charged with submitting an assessment to Congress on the “ecological and economic consequences” of both harmful algal blooms and hypoxia. The assessments were to include “alternatives for reducing, mitigating, and controlling” harmful algal blooms and hypoxia. A number of other reports and assessments were also required, which were to all culminate in a plan to combat and reduce the impacts of harmful algal blooms. Additionally, the Act singled out the areas of the Northern Gulf of Mexico and the Great Lakes. For these two areas, the Act required additional progress reports and mitigation plans.
The Act has undergone a few amendments throughout the years. The amendments have expanded and/or renewed the duties of the Task Force and other state and federal actors. Most notably, amendments in 2014 created the national harmful algal bloom and hypoxia program (Program) and a comprehensive research plan and action strategy. Under the Program, the National Oceanic and Atmospheric Administration (NOAA) was charged with administering funding to programs combatting algal blooms and hypoxia, working with state, local, tribal, and international governments to research and address algal blooms and hypoxia, and supervising the creation and review of the action strategy, among other duties. The action strategy identified the “specific activities” that the Program should carry out, which activities each agency in the Task Force would be responsible for, and the parts of the country where even more specific research and activities addressing algal blooms and hypoxia would be necessary.
What changes are proposed?
SB 1057 would make a number of changes and additions to the current law. Overall, the goal of the bill seems to be to strengthen the federal government’s ability to research and respond to water pollution in the form of algal blooms and hypoxia. The most important amendments in the bill would:
- Add the Army Corps of Engineers to the list of agencies on the Task Force.
- Combine the sections on freshwater and coastal algal blooms, and require that scientific assessments be submitted to Congress every five years for both types of water.
- Establish a website that would provide information about the harmful algal bloom and hypoxia program (Program) activities to “local and regional stakeholders.”
- Require the Task Force to work with extension programs to promote the Program and “improve public understanding” about harmful algal blooms and hypoxia.
- Require the use of “cost effective methods” when carrying out the law.
- Require the development of “contingency plans for the long-term monitoring of hypoxia.”
- Fund the Program and the comprehensive research plan and action strategy from 2019 through 2023.
Most importantly, SB 1057 would add a completely new section to the law that would allow federal officials to “determine whether a hypoxia or harmful algal bloom event is an event of national significance.” Under the new language, the federal official can independently determine that such an event is occurring, or the Governor of an affected state can request that a determination to be made.
When making the determination, the federal official would have to take a number of factors into consideration including:
- Toxicity of the harmful algal bloom;
- Severity of the hypoxia;
- Potential to spread;
- Economic impact;
- Relative size in relation to the past five occurrences of harmful algal blooms or hypoxia events that occur on a recurrent or annual basis; and
- Geographic scope, including the potential to affect several municipalities, to affect more than one State, or to cross an international boundary.
Finally, in the case an event of national significance is found, the the federal official would have the power to give money to the affected state or locality to mitigate the damages. However, SB 1057 states that the federal share of money awarded cannot be more than 50% of the cost of any activity. The federal official would have the power to accept donations of “funds, services, facilities, materials, or equipment” to supplement the federal money.
