The Issue How can we achieve our stated national goal of protecting our remaining wetlands?
When the first English colonists settled along the banks of the James River in 1607, nearly ten percent of the land that would become the continental United States (more than 221 million acres) was comprised of wetlands — including marshes, swamps, bogs, and various kinds of bottomlands. Since that time, Americans have filled, drained and dredged these wetlands in remorseless fashion. Less than half of the original acreage (roughly 105 million acres) survive today in the continental United States, of which 95 percent are inland freshwater wetlands, while the remaining five percent are saltwater wetlands. Six states -- California, Ohio, Indiana, Illinois, Iowa, and Missouri -- have lost 85 percent or more of their original wetlands, while 22 other states ranging from New York to Alabama to Idaho have lost 50 percent or more.
Due to prolific plant life, wetlands rank among the most productive ecosystems in the world. They produce tremendous amounts of vegetation that provide cover for fish and wildlife, nesting areas for birds, and nourishment for many aquatic invertebrates, shellfish, and forage fish, which, in turn provide food for larger fish. Wetlands serve as a home for a wide array of rare plants and numerous endangered and threatened animal species. Wetlands also improve water quality by removing nutrients and trapping sediments before they flow into open waters. In addition, wetlands provide flood protection all along America's rivers and streams by serving as storage basins during periods of high water. And especially important in light of the devastation wrought by Hurricane Katrina, intact coastal wetlands are effective storm buffers that absorb wave action and reduce storm surge. Finally, wetlands serve as a natural recharge point for groundwater (which is often used for drinking water, especially along our coasts); they help to even out stream flows (thus lessening the effects of occasional drought conditions); and they can remove the greenhouse gas carbon dioxide from the atmosphere.
The immense value of wetlands, however, was discovered rather late in the day. The 19th and early 20th centuries witnessed the conversion of millions of acres of wetlands to croplands and the harvesting of millions of acres of forested wetlands. This kind of destruction intensified during the 20th century as such water projects as dams, canals, and channelization projects became larger and as modern technology enabled farmers and others to more easily drain or fill wetland areas. From the mid-1950s through the mid-1970s, wetland losses in the United States averaged 550,000 acres per year.
The implementation of section 404 of the Clean Water Act has helped to bring about a dramatic decline in the destruction of wetlands. From the mid-1970s to the mid-1980s, wetlands losses in the continental United States fell to about 290,000 acres a year---half the earlier rate. And beginning in the mid-1980s, federal efforts to protect wetlands improved, due in part to new conservation programs created by various farm bills, with the result that annual wetlands losses dropped to approximately 58,500 acres per year between 1986 and 1997. The loss of biologically productive wetlands has continued in the years since 1997. In fact, a disturbing report issued by the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration in 2009 indicated that wetlands losses in the coastal watersheds of the Eastern United States alone amounted to some 59,000 acres per year between 1998 and 2004.
What People Are Fighting About
While an improvement over our previous record, the continuing loss of thousands of acres of productive wetlands every year flies in the face of a Presidential-level policy established in 1989 that sets a national goal of "no net loss" of wetlands. The continuing net loss of wetlands is due to a number of factors.
What's At Stake? A continued national commitment to protect vital aquatic habitats which often also contain threatened and endangered species.
Corps-Mandated Mitigation Left Undone. The U.S. Army Corps of Engineers, the primary regulatory authority for the wetlands program, permits approximately 24,000 acres of wetlands to be filled each year with the concomitant requirement that some 42,000 acres of wetlands be restored, created, enhanced, or sometimes merely preserved as compensatory mitigation. However, many of these mitigation projects have not been carried out, even though required by Corps-issued permits, and compliance inspections have been rare. Even when mitigation projects have been initiated, many mitigation sites are not performing well.
Feeble Enforcement. Enforcement against illegal dredges and fills has not been aggressive enough.
Supreme Court Decisions Undercutting the Effort. Two recent Supreme Court decisions have narrowed the jurisdictional reach of section 404 by stressing the term “navigable” in the Clean Water Act (CWA).
The Supreme Court’s 2001 decision in Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers ("SWANCC") began this narrowing process when it held that section 404 of the CWA did not apply to isolated, non-navigable, intrastate wetlands based solely on their use by migratory birds that cross state lines.
Then in 2006, the Supreme Court reviewed two cases in which the lower courts held that certain wetlands not adjacent to navigable waters were covered by the CWA. Rapanos v. United States. While four justices would have upheld these holdings, five justices disagreed. Those five justices, however, could not agree upon a common jurisdictional test. Four justices, in a plurality opinion, found that the Act extends only to “relatively permanent, standing or continuously flowing bodies of water” connected to traditional navigable waters and to wetlands with a continuous surface connection to such waters. Justice Kennedy agreed with the judgment but concluded that wetlands may be regulated if they “either alone or in combination with similarly situated lands in the region” have a “significant nexus” with traditional navigable waters. Rapanos has produced considerable confusion. Many, but not all lower courts, have held that Justice Kennedy’s concurrence, representing the narrowest ground for decision, is the controlling test. The EPA and the Corps, however, have followed the suggestion made in a dissenting opinion that either the plurality approach or Justice Kennedy’s approach may be applied, whichever one would support an assertion of jurisdiction, since the dissenters would have upheld jurisdiction in the case.
The Corps and EPA’s Interpretation of the Court’s Rulings. A guidance document issued by EPA and the Corps in 2008 raises a number of concerns. First, the guidance limits the agencies in determining whether a “significant nexus” exists to an aggregation of similar wetlands along a particular tributary rather than taking a broader, regional approach as discussed in Justice Kennedy’s opinion. This will obstruct efforts to take a broader, watershed approach to protecting aquatic resources and may leave many headwaters and associated wetlands unprotected. Second, the jurisdictional terms used in the opinion — “relatively permanent” and “significant nexus” — are legal terms, not scientific concepts. Applying these legal terms in the field will be a difficult enterprise involving both data collection and additional analysis in an effort to evaluate, both geographically and temporally, the relationship of a water to a traditionally navigable water. Such determinations, if done correctly, will take much case-by-case effort and will create considerable burdens for both the agencies and citizens.
Many legal challenges to wetlands jurisdiction have followed in the wake of SWANCC and Rapanos. Challengers have argued, for example, that many wetlands adjacent to non-navigable tributaries of navigable waters are not protected by the CWA and that wetlands adjacent to navigable waters lack protection in the absence of a hydrological connection to a navigable water. Litigation addressing these issues has created considerable uncertainty and has endangered the continued existence of millions of acres of our remaining wetlands. Meanwhile, Congress has cut much of the funding for the agricultural conservation programs that have served, in the past, to discourage the conversion of wetlands to dry land and have encouraged wetland conservation and restoration through subsidies.
A Progressive Perspective
The protection of our remaining wetlands remains a crucial ingredient of the nation's long-standing commitment to improving water quality and preserving its rich biodiversity. The protection of wetlands should also form a foundation for a new, more ecologically friendly, and ultimately more humane strategy for dealing with the dangers posed by floods, hurricanes, and similar natural disasters. Wetlands, those areas that are saturated or inundated by ground or surface water often enough to support a prevalence of wetland vegetation, are as much waters of the United States as any flowing stream. They are vital public resources whose loss adversely affects the well-being of the entire community.
Decisions on the Table
+ Whether Congress will revisit wetlands jurisdiction to eliminate the narrowing effects of SWANCC and Rapanos and ensure that activities that drain wetlands are regulated.
+ Whether EPA and the Corps will revise their guidance to make it clear that wetlands jurisdiction will exist if the wetlands in question when viewed in combination with similarly situated wetlands in that watershed have a “significant nexus” to a traditionally navigable water.
+ Whether Congress will adequately fund EPA, Corps, and Department of Agriculture programs to ensure conservation of our remaining wetlands.
+ Whether Congress will commission a study to evaluate the impact of current policies on wetland conservation.
To address the current challenges to the health of the nation's wetlands, a number of steps should be taken:
Enacting federal legislation that would close the loopholes created by the SWANCC and Rapanos decisions and end the efforts by developers and others to use these decisions as devices for paring back the protection of our nation's remaining wetlands. Such legislation would delete the word "navigable" from the CWA to make it absolutely clear that the CWA is intended to protect all of the waters of the United States including isolated waters and wetlands, as well as headwaters and intermittent waters. The amendment would also set forth an explicit legislative foundation for Congress's assertion of federal jurisdiction over these waters and would clearly extend jurisdiction over activities that destroy wetlands by draining them, rather than just by filling them.
Revising the 2008 Corps and EPA guidance memorandum, which provides that only similarly situated wetlands along a particular tributary will be analyzed in deciding whether a “significant nexus” exists with a traditionally navigable water.
Adding staffing resources for the U.S. Army Corps of Engineers to enable it to make jurisdictional determinations (which are now often very complicated exercises), fully analyze permit applications, monitor existing permit conditions including mitigation conditions, and enforce the law.
Adding staffing resources for the U.S. Environmental Protection Agency and the U.S. Fish and Wildlife Service to equip them to fully exercise their oversight and commenting responsibilities under section 404, including EPA’s obligation to review the more difficult jurisdictional determinations made by the Corps.
Vigorously enforcing the wetlands provisions of the CWA by the federal government.
Establishing and then providing adequate funding for state regulatory programs to protect wetlands that are no longer protected by federal law.
Restoring adequate funding levels for the wetlands conservation programs administered by the U.S. Department of Agriculture.
Initiating a thorough and impartial scientific study to determine, among other things: the current condition of America's wetlands; recent trends of wetlands losses not only in terms of acreage but also in terms of quality; the effectiveness and respective contributions of the various regulatory and non-regulatory programs aimed at wetlands preservation; whether the general permit program needs reform (since some 12,000 acres of wetlands loss occurs every year through general permits); and the actual environmental cost in terms of the loss of high value wetlands and in terms of the overall net loss of wetlands of the Corps' program which authorizes so-called "mitigation" to justify the issuance of section 404 permits.
