ABOUT MITIGATION BANKING

Mitigation bank means a site, or suite of sites, where resources (e.g., wetlands, streams, riparian areas) are restored, established, enhanced, and/or preserved for the purpose of providing compensatory mitigation for impacts authorized by DA permits. In general, a mitigation bank sells compensatory mitigation credits to permittees whose obligation to provide compensatory mitigation is then transferred to the mitigation bank sponsor. The operation and use of a mitigation bank are governed by a mitigation banking instrument.

Mitigation banking instrument means the legal document for the establishment, operation, and use of a mitigation bank.

Release of credits means a determination by the district engineer, in consultation with the IRT, that credits associated with an approved mitigation plan are available for sale or transfer, or in the case of an in-lieu fee program, for fulfillment of advance credit sales.

A proportion of projected credits for a specific mitigation bank or in-lieu fee project may be released upon approval of the mitigation plan, with additional credits released as milestones specified in the credit release schedule are achieved.

About Compensatory Mitigation

I. Background
Compensatory mitigation involves actions taken to offset unavoidable adverse impacts to wetlands, streams and other aquatic resources authorized by Clean Water Act section 404 permits and other Department of the Army (DA) permits.

As such, compensatory mitigation is a critical tool in helping the federal government to meet the longstanding national goal of ‘‘no net loss’’ of wetland acreage and function.

For impacts authorized under section 404, compensatory mitigation is not considered until after all appropriate and practicable steps have been taken to first avoid and then minimize adverse impacts to the aquatic ecosystem pursuant to 40 CFR part 230 (i.e., the CWA Section 404(b)(1) Guidelines).

Compensatory mitigation can be carried out through four methods: the restoration of a previously-existing wetland or other aquatic site, the enhancement of an existing aquatic site’s functions, the establishment (i.e., creation) of a new aquatic site, or the preservation of an existing aquatic site.

When compensating for impacts to marine resources, the location of the compensatory mitigation site should be chosen to replace lost functions and services within the same marine ecological system (e.g., reef complex, littoral drift cell).

MORE DEFINITIONS

Buffer means an upland, wetland, and/or riparian area that protects and/or enhances aquatic resource functions associated with wetlands, rivers, streams, lakes, marine, and estuarine systems from disturbances associated with adjacent land uses.

Compensatory mitigation means the restoration (re-establishment or rehabilitation), establishment (creation), enhancement, and/or in certain circumstances preservation of aquatic resources for the purposes of offsetting unavoidable adverse impacts which remain after all appropriate and practicable avoidance and minimization has been achieved

Off-site means an area not located on the same parcel of land as the impact site, nor on a parcel of land contiguous to the parcel containing the impact site.

On-site means an area located on the same parcel of land as the impact site, or on a parcel of land contiguous to the impact site.

Out-of-kind means a resource of a different structural and functional type from the impacted resource.

Preservation means the removal of a threat to, or preventing the decline of, aquatic resources by an action in or near those aquatic resources. This term includes activities commonly associated with the protection and maintenance of aquatic resources through the implementation of appropriate legal and physical mechanisms. Preservation does not result in a gain of aquatic resource area or functions.

Re-establishment means the manipulation of the physical, chemical, or biological characteristics of a site with the goal of returning natural/ historic functions to a former aquatic resource. Re-establishment results in rebuilding a former aquatic resource and results in a gain in aquatic resource area and functions.

Reference aquatic resources are a set of aquatic resources that represent the full range of variability exhibited by a regional class of aquatic resources as a result of natural processes and anthropogenic disturbances.

Rehabilitation means the manipulation of the physical, chemical, or biological characteristics of a site with the goal of repairing natural/ historic functions to a degraded aquatic resource. Rehabilitation results in a gain in aquatic resource function, but does not result in a gain in aquatic resource area.

Release of credits means a determination by the district engineer, in consultation with the IRT, that credits associated with an approved mitigation plan are available for sale or transfer, or in the case of an in-lieu fee program, for fulfillment of advance credit sales.

A proportion of projected credits for a specific mitigation bank or in-lieu fee project may be released upon approval of the mitigation plan, with additional credits released as milestones specified in the credit release schedule are achieved.

The appropriate watershed scale to use for the watershed approach will vary by geographic region, as well as by the particular aquatic resources under consideration.

Since using a watershed approach is not appropriate in areas without watershed boundaries, such as marine waters, we have also added a provision (§ 332.3(c)(2)(v) [§ 230.93(c)(2)(v)]) to clarify that other types of spatial scales may be more appropriate in those areas.

A few commenters remarked that the proposed rule does not adequately address compensatory mitigation for marine habitats or aquatic species.

We have revised the final rule to better incorporate principles of ecological restoration and landscape ecology, for example, at § 332.3(d) [§ 230.93(d)], which specifies detailed factors for the district engineer to use in determining ecological suitability for mitigation project sites.

Section 404 directs the Corps to issue permits for discharges of dredge and fill material, not to promote ‘‘active management’’ of wetlands. To the extent that active management may provide an alternative to permitted discharges, permit applicants should consider such approaches as part of the avoidance and minimization mitigation sequencing.

Also, both permitted projects and compensatory mitigation projects may require on-going active management to protect resources, and conditions for such management may be incorporated into DA permits where appropriate.

Finally, management of existing wetlands may itself involve discharges requiring DA permits, and in this case permit conditions will address issues related to the management and protection of affected resources, in accordance with applicable regulations, including this rule. We disagree that the rule does not adequately address marine habitats and species. While the specific projects needed to mitigate impacts to marine resources may be different, the procedural and analytical framework established in the final rule applies equally well to freshwater and marine resources.

Several commenters said that the proposed rule did not address concerns raised in recent reports on compensatory mitigation in the Corps Regulatory Program that were issued by the Government Accountability Office (GAO). Some commenters said that the proposed rule incorporates some of GAO’s recommendations, but expressed skepticism that the Corps has the resources to implement those provisions of this rule. These commenters asserted that the Corps needs to make compensatory mitigation compliance a high priority to ensure effective replacement of wetland acreage and function lost as a result of permitted activities.

Since that provision was last promulgated in 1986, there have been policy changes that have resulted in the Corps requiring compensatory mitigation for more activities, not just those that result in significant resource losses. For example, when the nationwide permit regulations were revised in 1991, a provision was added (33 CFR 330.1(e)(3)) which stated that compensatory mitigation could be required by a district engineer to ensure that an NWP activity results in minimal adverse environmental effects.

The final rule issued today also specifically states that it does not alter the regulations of 33 CFR 320.4(r), and that it supersedes certain guidance documents on compensatory mitigation. What is generally understood to be compensatory mitigation today (i.e., the restoration, establishment, enhancement, and/or preservation of aquatic resources) is in the 404(b)(1) Guidelines as an action to minimize adverse effects on populations of plants and animals (see 40 CFR 230.75(d)).

Compensatory mitigation may also be required to satisfy other legal requirements, as a result of the public interest review process, or to compensate for other resource losses. As indicated in the preamble to this rule, today’s rule does not affect the determination as to when compensatory mitigation is required, only the requirements for conducting such mitigation once the district engineer determines that it is necessary.

As stated in the preamble to the March 28, 2006, proposed rule (71 FR 15524–15525), this rule does not change the threshold for determining when compensatory mitigation is required; instead it focuses on where and how compensatory mitigation will be provided. The threshold for determining when compensatory mitigation is required for DA permits is generally addressed through 33 CFR 320.4(r) and specifically for the nationwide permits at 33 CFR 330.1(e)(3). projects.

Riparian areas. One commenter suggested defining this term more narrowly, to specify the type of vegetation that characterizes riparian areas. One commenter recommended modifying this definition to limit it to open waters, since wetlands are also considered to be waterbodies.

We have modified the first sentence of this definition to clarify that riparian areas are lands adjacent to streams, rivers, lakes, and marine-estuarine shorelines. To simplify this definition, we have also removed the second sentence of the proposed definition.

In this paragraph, we have added a provision to address compensating for impacts to marine resources. This provision states that compensatory mitigation project sites for marine resources should be located in the same marine ecological system as the impact site, citing reef complexes and littoral drift cells as examples of marine ecological systems. We have also added provisions indicating that compensation for impacts to aquatic resources in coastal watersheds should be located in a coastal watershed where practicable,

To enhance the use of the watershed approach, we have added a sentence to § 332.3(c)(2)(iv) [§ 230.93(c)(2)(iv)] stating that the identification and prioritization of resource needs should be as specific as possible.

(e) Dispute resolution process. (1) Within 15 days of receipt of the district engineer’s notification of intent to approve an instrument or amendment, the Regional Administrator of the U.S. EPA, the Regional Director of the U.S. Fish and Wildlife Service, the Regional Director of the National Marine Fisheries Service, and/or other senior officials of agencies represented on the IRT may notify the district engineer and other IRT members by letter if they object to the approval of the proposed final instrument or amendment.

This letter must include an explanation of the basis for the objection and, where feasible, offer recommendations for resolving the objections. If the district engineer does not receive any objections within this time period, he may proceed to final action on the instrument or amendment.

(2) The district engineer must respond to the objection within 30 days of receipt of the letter. The district engineer’s response may indicate an intent to disapprove the instrument or amendment as a result of the objection, an intent to approve the instrument or amendment despite the objection, or may provide a modified instrument or amendment that attempts to address the objection. The district engineer’s response must be provided to all IRT members.

(3) Within 15 days of receipt of the district engineer’s response, if the Regional Administrator or Regional Director is not satisfied with the response he may forward the issue to the Assistant Administrator for Water of the U.S. EPA, the Assistant Secretary for Fish and Wildlife and Parks of the U.S. FWS, or the Undersecretary for Oceans and Atmosphere of NOAA, as appropriate, for review and must notify the district engineer by letter via electronic mail or facsimile machine (with copies to all IRT members) that the issue has been forwarded for Headquarters review.

This step is available only to the IRT members representing these three federal agencies, however other IRT members who do not agree with the district engineer’s final decision do not have to sign the instrument or amendment or recognize the mitigation bank or in-lieu fee program for purposes of their own programs and authorities.
