RE: Changes in Regulation of Isolated Wetlands - SWANCC Decision
Dear Client/Colleague:
You may be aware of the recent U.S. Supreme Court Decision Solid Waste Agency of Northern
Cook County (SWANCC) v. United States Army Corps of Engineers (ACOE), referred to herein
as SWANCC, that limits the scope of the ACOE regulatory permitting program. I wanted
provide you with a brief synopsis of the position of the regulatory agencies regarding the
implications of this decision and how it might affect projects with which you are currently
involved.
I recently attended the Annual Conference of the New York
State Wetlands Forum (April 11 &12, 2001). In attendance were
representatives of the state and federal agencies involved with wetland
regulations. I will not provide details of the legal issue or history of SWANCC
and the 404 Regulatory program in this letter. To quote one speaker from the
U.S. Environmental Proteectionn Agency (EPA), "It's a mess." To view the SWANCC
decision on the internet, go here.
However, in terms of practical implications, several important conclusions were made at the
conference that I can share with you. There is general agreement that the SWANCC decision
limits the scope of the ACOE to regulate isolated wetlands under Section 404 of the Clean Water
Act. At this time, the ACOE will continue to regulate all wetlands that meet the criteria of being
adjacent (bordering or connected to) tributaries of major water bodies.
There is currently no guidance from the ACOE on how to define "isolated wetlands." It sounds
like it may be months before any guidance will be forthcoming. In the interim, the ACOE will
continue to process jurisdictional determinations and permit requests. The ACOE is advising that
any new delineations of wetlands should include all wetlands (including isolated ones) within the
project area. In addition, applicants should collect as much information as possible to document
the hydrology of the wetlands, and determine all possible surface connections to other wetlands or
tributaries. This in some cases will be difficult to do, of course, since the connections may be on
adjacent parcels to which we may not have access. Applicants are encouraged by the ACOE to
provide interpretation and justification for any wetlands they believe to be "isolated."
This means, simply, that if you have a wetland on your property that has no surface water
connection to any other wetland or water body (including small streams and ditches), it may not
currently be regulated by the ACOE, regardless of its size. However, it must also be able to be
argued that loss of that wetland will not cause significant degradation (flooding, etc.) to other
regulated wetlands or waterways. Also, please keep in mind, this does not alter in any way the
jurisdiction for wetlands regulated by the New York Department of Environmental Conservation
(DEC) or the Adirondack Park Agency (APA).
In addition, if an isolated wetland was part of an earlier permit or approved delineation, it may be
possible to have the ACOE review them and potentially "adjust" the extent of the jurisdiction and
also the mitigation required, if the project permit included mitigation.
It is clear that the full impacts of SWANCC v. USACOE will not be apparent for some time. However, in the short term, the USACOE's regulation of isolated wetlands will be dramatically reduced. For areas such as poorly drained farm fields, created ponds and isolated depressions with no outlets, that do not fall under DEC regulation, there may be a dramatic change in regulation until clarification comes from the agencies or through additional court decisions.
