A mitigation bank is a wetland, stream, or other aquatic
resource area that has been restored, established, enhanced, or (in
certain circumstances) preserved for the purpose of providing
compensation for unavoidable impacts to aquatic resources permitted
under Section 404 or a similar state or local wetland regulation. A
mitigation bank may be created when a government agency, corporation,
nonprofit organization, or other entity undertakes these activities
under a formal agreement with a regulatory agency. Mitigation banks have
four distinct components:
The bank site: the physical acreage restored, established,
enhanced, or preserved;
The bank instrument: the formal agreement between the bank owners
and regulators establishing liability, performance standards,
management and monitoring requirements, and the terms of bank credit
approval;
The Inter-agency Review Team (IRT): the inter-agency team that
provides regulatory review, approval, and oversight of the bank
The service area: the geographic area in which permitted impacts
can be compensated for at a given bank.
The value of a bank is
defined in "compensatory mitigation credits." A bank's instrument
identifies the number of credits available for sale and requires the use
of ecological assessment techniques to certify that those credits
provide the required ecological functions. Although most mitigation
banks are designed to compensate only for impacts to various wetland
types, some banks have been developed to compensate specifically for
impacts to streams (i.e., stream mitigation banks). Mitigation banks are
a form of "third-party" compensatory mitigation, in which the
responsibility for compensatory mitigation implementation and success is
assumed by a party other than the permittee. This transfer of liability
has been a very attractive feature for Section 404 permit-holders, who
would otherwise be responsible for the design, construction, monitoring,
ecological success, and long-term protection of the site.

Benefits of Mitigation
Banking
Mitigation banking has a number of advantages
over traditional permittee-responsible compensatory mitigation because
of the ability of mitigation banking programs to:
Reduce uncertainty over whether the compensatory mitigation will
be successful in offsetting project impacts;
Assemble and apply extensive financial resources, planning, and
scientific expertise not always available to many
permittee-responsible compensatory mitigation proposals;
Reduce permit processing times and provide more cost-effective
compensatory mitigation opportunities; and
Enable the efficient use of limited agency resources in the review
and compliance monitoring of compensatory mitigation projects because
of consolidation.
In its 2001 critique of compensatory
mitigation, the National
Research Council (NRC) concluded that third-party compensatory
mitigation such as mitigation banks offer advantages over
permittee-responsible mitigation in the fulfillment of regulatory
goals.1 One such advantage
identified by NRC is the consensus-driven, interagency review process
used to approve banks.2 The
2002 National Mitigation Action Plan acknowledges that more expertise
and collaboration should be brought to bear on the Section 404
mitigation process. The 2008 Corps/EPA compensatory mitigation
regulations codify the consensus-based interagency review team approach
endorsed by the NRC. NRC also noted that banks are more likely than
traditional compensatory mitigation to achieve desired long-term
outcomes and to create mitigation sites that are protected in perpetuity
by organizations dedicated to resource
conservation.3 Additionally,
banking represents an increasingly important economic component of the
environmental consulting sector, showcasing the synergies that can arise
between effective environmental protection and economic expansion. Sixty
two percent of the banks identified in ELI's 2002 study were
privately-owned entrepreneurial mitigation banks; entrepreneurial
providers of bank credits have emerged as a nationally-organized
industry4 contributing hundreds of
millions of dollars annually to the domestic product.
