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.

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.

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.
NOAA Trust Resources— NOAA resources are found in, under, or using waters navigable by deep draft vessels, tidally influenced waters, or waters of the contiguous zone, the exclusive economic zone, and the outer continental shelf. Examples include, commercial and regional fishery resources; migratory fish species; marine mammals; endangered and threated marine species and their habitats, and resources associated with National Marine Sanctuaries and National Estuarine Research Reserves.
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.

restoration—The goal of a natural resource damage assessment, which involves rehabilitating, replacing, or acquiring the equivalent of injured natural resources and the services they provided. Restoration includes both primary and compensatory restoration projects.
restoration banking - An arrangement where natural resource trustees agree to recognize and accept restoration credits produced by a third party, in lieu of payment of funds by the settling party, or, in lieu of promises by the settling party to perform restoration work. Restoration banking arrangements may also cover situations where trustees directly purchase restoration credits generated by third party projects using funds separately recovered from potentially responsible parties (PRP). The restoration project producing the credits is often referred to as a restoration bank, and may consist of a project or projects developed by one or a group of PRPs who produce more restoration credits than required to satisfy their own liability. It may also consist of a project or projects developed by a non-PRP third party, as an intended profit-making venture, or to serve other goals.
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.
