In Solid Waste Agency of Northern Cook County (SWANCC) v. U.S. Army Corps of Engineers, the U.S. Supreme Court recently held that the U.S. Army Corps of Engineers (the Corps) does not have authority under the Clean Water Act (the Act or the CWA) to regulate the filling of "other waters." This decision demonstrates a major shift in the Court's approach to statutory interpretation, particularly in the context of reviewing an agency's understanding of a statute. The significance of the case is best gauged by contrasting it with United States v.

For the last several years, federal circuit courts have debated the exact jurisdictional scope of §404 of the Clean Water Act (CWA), which authorizes the Secretary of the U.S. Army (the Army), acting through the U.S. Army Corps of Engineers (the Corps), to issue permits "for the discharge of dredged or fill material into the navigable waters at specified disposal sites." The circuit courts have based their debates on the assumption, well-supported by earlier CWA decisions, that Congress intended the term "navigable waters" within the CWA to extend to the limits of the U.S. Commerce Clause.

Environmentalists are no strangers to disappointment in the U.S. Supreme Court, but the recent case of Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers (SWANCC) is particularly disappointing. First, it might be said that the impact of the opinion, in circumstances in which legislative amendment is virtually impossible, may be the most devastating judicial opinion affecting the environment ever.

This past January, the U.S. Supreme Court held that the Clean Water Act (CWA) did not authorize the federal government to prohibit a landfill operator from filling isolated ponds on its property merely because the ponds were used as habitat by migratory birds. The National Association of Home Builders claimed that the decision in Solid Waste Agency of Northern Cook County v. U.S.

For over two decades, courts and agencies have assumed that the Clean Water Act (CWA) grants the U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (Corps) jurisdiction over the nation's waters to the full extent of the U.S. Congress' authority under the U.S. Constitution's Commerce Clause. This belief led the Corps and EPA to assert CWA jurisdiction over virtually all waters in the nation, including navigable waters; non-navigable tributaries; adjacent wetlands; and non-navigable, isolated, intrastate waters and wetlands.

In the wake of the U.S. Supreme Court's decision in Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers (SWANCC), courts have scrambled to reevaluate the scope and reach of the government's regulatory authority over "navigable waters" pursuant to the Clean Water Act (CWA). A growing majority of courts, especially the U.S. Court of Appeals for the Fourth Circuit, the U.S. Court of Appeals for the Sixth Circuit, the U.S. Court of Appeals for the Seventh Circuit, and the U.S.

Editors' Summary: This Article is the first in a series intended to supplement Federal Wetlands Law, a primer that ELR published in 1993 and subsequently incorporated into the Wetlands Deskbook. The Article, which refers to the primer but stands on its own, focuses primarily on where wetlands law has changed since publication of the primer. The Article first provides an update of legislative and executive branch developments in wetlands law and policy.

Editors' Summary: Combined sewer overflows and sanitary sewer overlows present unique problems for regulators. Although these problems were largely ignored until recently, EPA has finally begun to address the significant environmental and public health hazards these pollution sources pose. The author first provides a brief overview of the problems of combined and sanitary sewer overflows and the basis for their regulation under the FWPCA. He next discusses EPA's policy and guidance efforts to date, including the relevant documents' specific requirements and the concerns that shaped them.

Nearly three decades after enactment of the modern Clean Water Act (CWA), efforts to address the largest remaining source of water pollution—runoff and other types of aquatic ecosystem impairment from diffuse activities—remain elusive. Every two years, the U.S. Environmental Protection Agency (EPA) confirms in its biennial National Water Quality Inventory that nonpoint source water pollution, or "polluted runoff," causes the majority of water body impairment throughout the country.

Thirty years in the making, the total maximum daily load (TMDL) program of §303(d) of the Clean Water Act (CWA) has never seemed farther from implementation. As state governments increasingly have flexed their regulatory muscles with respect to the environment, ironically they have shied away—to put it mildly—from their environmental responsibilities under the TMDL program. Their reticence and outright opposition to improving water quality are that much more striking given their adamant insistence in 1972 that this obligation be reserved to and exercised by them.
