The United States Army Corps of Engineers (USACE) is the military engineering branch of the United States Army. A direct reporting unit (DRU), it has three primary mission areas: Engineer Regiment, military construction, and civil works. USACE has 37,000 civilian and military personnel, making it one of the world's largest public engineering, design, and construction management agencies. The USACE workforce is approximately 97% civilian, 3% active duty military. The civilian workforce is primarily located in the United States, Europe and in select Middle East office locations. Civilians do not function as active duty military and are not required to be in active war and combat zones; however, volunteer opportunities do exist for civilians to do so.
The Intracoastal Waterway (ICW) is a 3,000-mile (4,800 km) inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Massachusetts southward along the Atlantic Seaboard and around the southern tip of Florida, then following the Gulf Coast to Brownsville, Texas. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea.
The Clean Water Act (CWA) is the primary federal law in the United States governing water pollution. Its objective is to restore and maintain the chemical, physical, and biological integrity of the nation's waters; recognizing the responsibilities of the states in addressing pollution and providing assistance to states to do so, including funding for publicly owned treatment works for the improvement of wastewater treatment; and maintaining the integrity of wetlands.
Water right in water law is the right of a user to use water from a water source, e.g., a river, stream, pond or source of groundwater. In areas with plentiful water and few users, such systems are generally not complicated or contentious. In other areas, especially arid areas where irrigation is practiced, such systems are often the source of conflict, both legal and physical. Some systems treat surface water and ground water in the same manner, while others use different principles for each.
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and calm enough for a water vessel to pass safely. Navigability is also referred to in the broader context of a body of water having sufficient under keel clearance for a vessel.
The inland waterways of the United States include more than 25,000 mi (40,000 km) of navigable waters. Much of the commercially important waterways of the United States consist of the Mississippi River System—the Mississippi River and connecting waterways.
The Refuse Act is a United States federal statute governing use of waterways. The Act, a section of the Rivers and Harbors Act of 1899, prohibited "dumping of refuse" into navigable waters, except by permit.
Rapanos v. United States, 547 U.S. 715 (2006), was a United States Supreme Court case challenging federal jurisdiction to regulate isolated wetlands under the Clean Water Act. It was the first major environmental case heard by the newly appointed Chief Justice, John Roberts, and Associate Justice Samuel Alito. The Supreme Court heard the case on February 21, 2006, and issued a decision on June 19, 2006.
The Water Resources Development Act of 1986 is part of Pub. L. 99–662, a series of acts enacted by Congress of the United States on November 17, 1986.
Rivers and Harbors Act may refer to one of many pieces of legislation and appropriations passed by the United States Congress since the first such legislation in 1824. At that time Congress appropriated $75,000 to improve navigation on the Ohio and Mississippi rivers by removing sandbars, snags, and other obstacles. Like when first passed, the legislation was to be administered by the United States Army Corps of Engineers (USACE), under its Chief Engineer and the Secretary of War.
The Water Resources Development Act of 1992, Pub. L. 102–580, was enacted by Congress of the United States on October 31, 1992. Most of the provisions of WRDA 1992 are administered by the United States Army Corps of Engineers.
Solid Waste Agency of Northern Cook County (SWANCC) v. U.S. Army Corps of Engineers, 531 U.S. 159 (2001), was a decision by the US Supreme Court that interpreted a provision of the Clean Water Act. Section 404 of the Act requires permits for the discharge of dredged or fill materials into "navigable waters," which is defined by the Act as "waters of the United States." That provision was the basis for the federal wetlands-permitting program.
"No Net loss" is the United States government's overall policy goal regarding wetlands preservation. The goal of the policy is to balance wetland loss due to economic development with wetlands reclamation, mitigation, and restorations efforts, so that the total acreage of wetlands in the country does not decrease, but remains constant or increases.
United States v. Riverside Bayview, 474 U.S. 121 (1985), was a United States Supreme Court case challenging the scope of federal regulatory powers over waterways as pertaining to the definition of "waters of the United States" as written in the Clean Water Act of 1972. The Court ruled unanimously that the government does have the power to control intrastate wetlands as waters of the United States. This ruling was effectively revised in Rapanos v. United States (2006), in which the Court adopted a very narrow interpretation of "navigable waters."
Point source water pollution comes from discrete conveyances and alters the chemical, biological, and physical characteristics of water. In the United States, it is largely regulated by the Clean Water Act (CWA). Among other things, the Act requires dischargers to obtain a National Pollutant Discharge Elimination System (NPDES) permit to legally discharge pollutants into a water body. However, point source pollution remains an issue in some water bodies, due to some limitations of the Act. Consequently, other regulatory approaches have emerged, such as water quality trading and voluntary community-level efforts.
The Waters of the United States Regulatory Overreach Protection Act of 2014 is a bill that would prohibit the Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (Corps) from implementing or enforcing certain proposed regulations regarding the use of the nation’s waters and wetlands.
The Clean Water Rule is a 2015 regulation published by the U.S. Environmental Protection Agency (EPA) and the United States Army Corps of Engineers (USACE) to clarify water resource management in the United States under a provision of the Clean Water Act of 1972. The regulation defined the scope of federal water protection in a more consistent manner, particularly over streams and wetlands which have a significant hydrological and ecological connection to traditional navigable waters, interstate waters, and territorial seas. It is also referred to as the Waters of the United States (WOTUS) rule, which defines all bodies of water that fall under U.S. federal jurisdiction. The rule was published in response to concerns about lack of clarity over the act's scope from legislators at multiple levels, industry members, researchers and other science professionals, activists, and citizens.
Oil Pollution Act of 1924 is a United States federal statute establishing regulations for coastal navigable waters with regards to intentional fossil fuel discharges from seagoing vessels. The Act of Congress grants the Secretary of War authority to evaluate the oil volume discharge from a vessel while assessing if coastal navigable waters have a potential toxicity posing a deleterious condition for human health and seafood contamination. The 1924 United States statute provides judicial penalties encompassing civil and criminal punishment for violations of the prescribed regulations as stated in the Act.
Sackett v. Environmental Protection Agency, 598 U.S. 651 (2023), also known as Sackett II, was a United States Supreme Court case in which the court held that only wetlands and permanent bodies of water with a "continuous surface connection" to "traditional interstate navigable waters" are covered by the Clean Water Act.
