CERCLA—The acronym for the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended by the Superfund Amendments and Reauthorization Act (SARA) in 1986, often referred to as Superfund. The federal statute establishes liability for site cleanup, prescribes a procedure for identifying and ranking contaminated sites, provides a funding mechanism for site cleanups, reduces uncontrolled releases of hazardous substances, establishes cleanup procedures that provide protection for humans and the environment, and restores injured natural resources through provisions administered by the natural resource trustees.

chlor-alkali The electrolysis process used in the manufacture of chlorine, hydrogen, sodium hydroxide (corrosive) solution. 

compensatory restoration projects—Projects to compensate for interim losses of natural resources and the services they provide—from the time of injury until recovery is completed.

consumption advisory— A federal, state, or local government recommendation to avoid eating a certain fish, shellfish, or other organism because it is unsafe due to high levels of contamination.

cooperative assessments—Assessments that are done cooperatively after an oil spill or hazardous substance release by trustees and the party responsible for the incident. This cooperation generally results in faster, more efficient restoration of injured natural resources.

CWA/Clean Water Act—The law (also called the Federal Water Pollution Control Act) that established the programmatic and regulatory framework for restoring and maintaining the chemical, physical, and biological integrity of the nation’s waters. The CWA generally prohibits discharges of oil and hazardous substances into coastal or ocean waters. The 1973 amendments mandated the development of a National Contingency Plan (NCP) that would "provide for efficient, coordinated and effective action to minimize damage from oil and hazardous substances discharges, including containment, dispersal, and removal of oil and hazardous substances." The NCP governs the actions of all federal agencies involved in responding to oil and hazardous material releases. It also defines roles for agencies that are natural resource trustees.

DARRP/Damage Assessment, Remediation, and Restoration Program—A multi-office program within NOAA involving the National Ocean Service, the National Marine Fisheries Service, and the Office of General Counsel. DARRP scientists, economists, and attorneys conduct natural resource damage assessments of and restoration projects for coastal and marine resources injured by oil and hazardous material releases.

DDT/dichloro-diphenyl-trichloroethane—A chemical compound commonly used as a pesticide until it was banned in the U.S. in 1972. However, DDT is still used in other parts of the world.

habitat—Place where an animal or plant normally lives, often characterized by a dominant plant form or physical characteristic.

HEA/habitat equivalency analysis—A method developed by NOAA for estimating how much restoration is needed to compensate for the loss of natural resources and their services from the time they are injured until they are returned to the condition they would have been in had the injury not occurred.

hazardous substance—Substances identified as capable of posing "imminent and substantial danger to public health and welfare or the environment." CERCLA has identified more than 800 hazardous substances. The term does not include petroleum or natural gas.

injury—An observable or measurable adverse change—including destruction, loss, and loss of use—in a natural resource, or impairment of a natural resource service.

injury assessment and restoration planning—The second phase of a natural resource damage assessment. Trustees identify the injuries to natural resources and their services and use that information to determine the need for and amount of restoration.

marine debris—Human-created waste that has deliberately or accidentally been released in a lake, sea, ocean, or waterway.

marsh—An emergent wetland seasonally flooded or usually wet and often dominated by one or a few plant species. Marshes can be either freshwater or saltwater.

National Marine Sanctuaries—Marine areas protected by law, identified for their biodiversity, ecological integrity, and cultural legacy.

National Marine Sanctuary Act—Legislation designed to identify, designate, and manage areas of the marine environment that are of special national significance due to their conservation, recreational, ecological, historical, scientific, educational, or aesthetic qualities.

natural resource services—Ecological and human services provided by natural resources that may be injured after an oil spill or hazardous substance release. Ecological services include flood control, sediment stabilization, and habitat. Human services include fishing, beachgoing, and wildlife viewing.

natural resource trustees (trustees)—Government officials who act on behalf of the public when there is injury to, destruction of, loss of, or threat to natural resources as a result of a release of a hazardous substance or a discharge of oil. Trustees include the U.S. Departments of Commerce, Interior, Defense, Agriculture, and Energy; state agencies; and Native American tribes. NOAA is the lead federal trustee for coastal and marine resources.

NOAA/National Oceanic and Atmospheric Administration—A U.S. Department of Commerce agency whose mission is to describe and predict changes in the earth's environment and to conserve and manage the nation's coastal and marine resources to ensure sustainable economic opportunities.

NRDA/natural resource damage assessment—Investigation performed by trustees to identify and plan the restoration of natural resources injured by oil spills and hazardous substance releases. The goal of NRDA is to restore natural resources.

OPA/Oil Pollution Act of 1990—Legislation designed to prevent oil spills, ensure cleanup if spills occur, and restore natural resources injured by these spills.

nutrient cycling—The continuous cycling through an ecosystem of minerals, compounds, or elements that promote biological growth or development.

PAHs/polycyclic aromatic hydrocarbons—A group of organic contaminants that are often the byproducts of petroleum processing or combustion. Many are toxic to aquatic life and several are suspected of causing cancer in humans.

PCBs/polychlorinated biphenyls—A class of chemicals previously used in manufacturing that remain in the environment for many decades, accumulate in living creatures, and pose health hazards to humans, wildlife, and fish.

preliminary assessment—The first step in a natural resource damage assessment, in which trustees determine whether injury to public trust resources has occurred or is likely to occur.

primary restoration projects—Projects to restore natural resources injured by oil or hazardous substance releases to the condition that would have existed if the incident had not occurred.

RAP/Rapid Assessment Program—A capability developed and supported by the Damage Assessment, Remediation, and Restoration Program to collect perishable data and readily available information to determine the need for a natural resource damage assessment.

responsible parties/potentially responsible parties—The individuals, companies, or government agencies responsible (or potentially responsible) for an oil spill, hazardous substance release, or ship grounding incident.

sediments—Loose particles of sand, clay, silt, and other substances that settle at the bottom of a water body. They come from eroding soil and from decomposing plants and animals. Wind, water, and ice often carry these particles great distances. Many sediments in rivers, lakes, and oceans are contaminated by pollutants, such as DDT and PCBs.

settlement—An agreement between natural resource trustees and responsible parties that specifies the terms under which liability is resolved.

slag—stony wate matter separated from metals during the smelting or refining of ore.

Superfund site—An uncontrolled or abandoned place where hazardous waste is located, possibly affecting local ecosystems or people. Sites are listed on the National Priorities List for evaluation and cleanup by the U.S. Environmental Protection Agency. See also: CERCLA.

SVOCs/semi-volatile organic compounds—A group of hazardous chemicals that accumulate in sediments and living creatures; PCBs, dioxins, and some pesticides are SVOCs.
