WETLAND AND CONSERVATION BANKING IN DETAILFederal Wetland Mitigation <strong>Banking</strong> PolicyUnder §404, compensa<strong>to</strong>ry mitigation is required as<strong>the</strong> third step <strong>of</strong> a three-step process designed <strong>to</strong> meet<strong>the</strong> goals <strong>of</strong> <strong>the</strong> CWA and support <strong>the</strong> national no netloss policy (see Box 1). The basic premise <strong>of</strong> <strong>the</strong> §404permitting program is that no discharge shall be permittedif a practicable alternative exists that is lessdamaging <strong>to</strong> <strong>the</strong> aquatic environment or <strong>the</strong> dischargewould cause <strong>the</strong> nation’s waters <strong>to</strong> be significantlydegraded. In order for a project <strong>to</strong> be permitted, itmust be demonstrated that, <strong>to</strong> <strong>the</strong> extent practicable,steps have been taken <strong>to</strong> avoid impacts <strong>to</strong> wetlandsand o<strong>the</strong>r aquatic resources, potential impacts havebeen minimized, and compensation will be providedfor any remaining unavoidable impacts. The three-partBox 1. Evolution <strong>of</strong> <strong>the</strong> Three-Part Mitigation SequenceIn 1980, EPA issued <strong>the</strong> final §404(b)(1) Guidelines; <strong>the</strong> regulations that established<strong>the</strong> environmental criteria by which <strong>the</strong> Corps evaluates dredge and fillpermit applications.(1) One <strong>of</strong> <strong>the</strong> central concepts embedded in <strong>the</strong> Guidelinesis that no discharges <strong>of</strong> dredged or fill material shall be permitted if <strong>the</strong>re is apracticable alternative <strong>to</strong> <strong>the</strong> proposed discharge that would have less adverseimpact on <strong>the</strong> aquatic environment, so long as that alternative does not haveo<strong>the</strong>r significant adverse environmental consequences.(2) In o<strong>the</strong>r words,impacts <strong>to</strong> aquatic resources must be avoided <strong>to</strong> <strong>the</strong> maximum extent practicable.The Guidelines also require that “appropriate and practicable steps” betaken <strong>to</strong> minimize potential adverse impacts <strong>to</strong> <strong>the</strong> aquatic ecosystem before adischarge can be permitted.(3) The Guidelines fur<strong>the</strong>r describe habitat “developmentand res<strong>to</strong>ration” as an appropriate method for compensating for permittedimpacts that destroy habitat.(4)In 1990, EPA and <strong>the</strong> Corps issued a Memorandum <strong>of</strong> Agreement (MitigationMOA) <strong>to</strong> elaborate upon <strong>the</strong> three-part mitigation requirements <strong>of</strong> <strong>the</strong>§404(b)(1) Guidelines.(5) The Mitigation MOA defines mitigation as a threepartsequence – avoidance, minimization, and compensation – each step <strong>of</strong>which has its origins in <strong>the</strong> Guidelines.(6)The Corps…first makes a determination that potential impacts have beenavoided <strong>to</strong> <strong>the</strong> maximum extent practicable; remaining unavoidable impactswill <strong>the</strong>n be mitigated <strong>to</strong> <strong>the</strong> extent appropriate and practicable by requiringsteps <strong>to</strong> minimize impacts and, finally, compensate for aquatic resourcevalues.(7)Resources: (1) 40 C.F.R. § 230 et. seq.; (2) 40 C.F.R. § 230.10(a); (3) 40 C.F.R. § 230.10(d); (4) 40C.F.R. § 230.75(d); (5) U.S. Environmental Protection Agency and U.S. Department <strong>of</strong> <strong>the</strong> Army.February 6, 1990. Memorandum <strong>of</strong> Agreement Between <strong>the</strong> Environmental Protection Agency and<strong>the</strong> Department <strong>of</strong> <strong>the</strong> Army Concerning <strong>the</strong> Determination <strong>of</strong> Mitigation Under <strong>the</strong> Clean Water ActSection 404(b)(1) Guidelines; (6) Mitigation MOA (1990), § II.A; (7) Mitigation MOA (1990), § II.C.mitigation sequence – avoid, minimize, compensate– represents <strong>the</strong> heart <strong>of</strong> <strong>the</strong> agencies’ §404 regula<strong>to</strong>ryprogram.Significant attention has been paid over <strong>the</strong> past 20years <strong>to</strong> improving <strong>the</strong> third step in <strong>the</strong> process - compensation- <strong>to</strong> ensure that compensa<strong>to</strong>ry mitigationefforts are “ecologically self-sustaining,” 9 protected inperpetuity, and ultimately meet <strong>the</strong> program’s no netloss goal. Although technically <strong>the</strong> term “mitigation”refers <strong>to</strong> all three steps <strong>of</strong> <strong>the</strong> three-part sequencingprocess, it is <strong>of</strong>ten used <strong>to</strong> describe <strong>the</strong> third step only.Satisfying <strong>the</strong> Third Step: CompensationCurrently, <strong>the</strong>re are three primary mechanisms supportedby EPA and <strong>the</strong> Corps for permittees <strong>to</strong> meet<strong>the</strong>ir compensa<strong>to</strong>ry mitigation obligations. These are:performing project-specific or permittee-responsiblemitigation, purchasing credits from a mitigation bank,or making a payment <strong>to</strong> an approved in-lieu fee mitigationsponsor. These last two forms <strong>of</strong> compensa<strong>to</strong>rymitigation – mitigation banking and in-lieu fee mitigation– are <strong>of</strong>ten referred <strong>to</strong> as “third party” mitigation,since <strong>the</strong> liability for meeting <strong>the</strong> compensa<strong>to</strong>rymitigation requirements is transferred <strong>to</strong> a third party.(For more on in-lieu fee mitigation see Chapter 4, “ATypology <strong>of</strong> Banks.”.)The Evolution <strong>of</strong> Wetland Mitigation <strong>Banking</strong>Although permittee-responsible mitigation has beenand remains <strong>the</strong> dominant mechanism for meetingcompensa<strong>to</strong>ry mitigation requirements (approximately60 percent <strong>of</strong> all required wetland mitigation nationwidewas satisfied by permittee-responsible mitigationin FY 2003), 10 wetland mitigation banking has becomeincreasingly prevalent since its emergence as an alternativein <strong>the</strong> mid-1980s.
