Laws and Permits

ACTS AND REGULATORY AGENCIES

Permitting Laws

Laws and regulations requiring permits for algaecide approval and deployment.

Primary

Federal Insecticide,

Fungicide, and Rodenticide

Act (FIFRA)

Regulates the use, sale, distribution, and registration of pesticides and algicides.

Learn More
Primary

Federal Food, Drug, and

Cosmetic Act (FFDCA)

Authorizes the EPA to set pesticide tolerances in foods, including products used in marine or freshwater sites where fish or shellfish may be exposed and consumed by humans.

Learn More
Primary

Pesticide Registration

Improvement Act (PRIA)

Establishes a fee-for-service system for pesticide registration at the EPA.

Learn More
Primary

Clean Water Act National

Pollutant Discharge

Elimination System (NPDES)

Prohibits anybody from discharging "pollutants" through a "point source" into a "water of the United States" unless they have an NPDES permit.

Primary

State Policies and Permits

Each state has its own pesticide permitting and registration process. Although additional regulations may apply, each state must follow the minimum pesticide requirements set forth by FIFRA. State-specific entities such as the Department of Natural Resources, Department of Public Health, and State Wildlife Commissions are often involved in the review of Experimental Use Permit applications and pesticide registration.

Primary

Marine Protection, Research

and Sanctuaries Act (MPRSA)

Regulates the intentional transportation and disposal of materials into ocean waters.

Learn More

Section 10 of the Rivers and

Harbors Act

Prohibits unauthorized obstruction or alteration of U.S. navigable waters. A permit from the USACE is required for work or structures in, over, or under these waters, including many water bodies and wetlands regulated by the Corps.

Learn More

Section 404 of the Clean

Water Act

A permit is required for the discharge of dredged or fill material into waters of the United States.

Learn More

Acts Requiring Compliance

Regulatory statutes with which the deployment of algaecide products must comply.

Endangered Species Act

Ensures actions authorized, funded, or carried out are not likely to jeopardize the continued existence of any listed species or result in the destruction or adverse modification of designated critical habitat of such species. EPA has an ecological risk assessment process for the evaluation of potential risk to endangered and threatened species from exposure to pesticides.

Learn More

Magnuson-Stevens Act

Protects habitat that fish need to spawn, breed, feed and grow to maturity and ensure a safe and sustainable supply of seafood.

Learn More

Marine Mammal Protection

Act (MMPA)

Prohibits the disturbance of a marine mammal or marine mammal stock in the wild by causing disruption of behavioral patterns, including but not limited to migration, breathing, nursing, breeding, feeding, or sheltering (Level B harassment).

Learn More

National Environment Policy

Act (NEPA)

Requires federal agencies to assess the environmental effects of their proposed actions prior to making decisions.

Learn More

Migratory Birds Treaty Act (MBTA)

Prevents the taking, possession, transportation, sale, purchase, barter, importation, exportation, and banding or marking of migratory birds unless otherwise permitted. Under the MBTA, “take” refers to bird death by intentional (hunting) or incidental means. As “incidental taking” may result from human activities that disturb bird behavior, migratory bird habitats essential to standard behaviors, including nesting, foraging, and migration, are also protected under this act.

Learn More

National Marine Sanctuaries Act (NMSA)

Authorizes the Secretary of Commerce to designate and protect areas of the marine environment with special national significance due to their conservation, recreational, ecological, historical, scientific, cultural, archeological, educational or esthetic qualities as national marine sanctuaries.

Learn More

Section 307 of the Coastal Zone Management

Act (CZMA)

Referred to as the “federal consistency” provision of the CZMA, gives states a strong voice in federal agency decision making, which they otherwise would not have, for activities that may affect a state’s coastal uses or resources.

CONTROL STRATEGIES

Types of HAB Control Technologies

Determining what type of product you have is key as each type has a different process for registration

Chemical

Biological

Physical

Minimum Risk Pesticides

Conventional Chemical

Biochemical Pesticides

Antimicrobial Pesticides

Minimum Risk Pesticides

Conventional Chemical

Conventional pesticides are all active ingredients other than biological pesticides and antimicrobial pesticides. Conventional active ingredients are generally produced synthetically, i.e., are synthetic chemicals that prevent, mitigate, destroy, or repel any pest; or that act as a plant growth regulator, desiccant, defoliant or nitrogen stabilizer.

Wood preservative and anti-foulant products that do not have antimicrobial uses and agricultural fungicide and aquatic herbicide products are either classified as a conventional or a biochemical pesticide. Biochemical pesticides with a toxic mode of action are classified for the purposes of the registration process as conventional pesticides.
