The Corps of Engineers (COE) and EPA issued the final rule (33 CFR 332 and 40 CFR 230) for implementing the compensatory mitigation program on April 10, 2008 for losses of aquatic resources from dredge and fill activities. The effective date of the rule is June 9, 2008. The most significant change to the regulation is the reversal of the COE on the use of in-lieu fee programs for compensatory mitigation (the proposed rule was issued with a 90 day phase out date for these types of programs).
Highlights of the rule are summarized below:
Where a project is located within the service area of an approved mitigation bank and credits in the bank are available for the type of resource impacted – mitigation requirements may be met by the purchase of an appropriate number of credits from the bank.
The watershed approach for compensatory mitigation requires use of an applicable or existing watershed plan. Where practicable and appropriate, the District Engineer (DE) will require the mitigation plant “compensatory mitigation” to be consistent with an established watershed plan or be determined using the principles of a watershed approach.
Where a plan is not available, the watershed approach should be based on information provided by the project sponsor or available from other sources.
Where a watershed approach is not practical – the DE will consider opportunities to offset anticipated aquatic resource impacts by requiring on-site and in-kind compensatory mitigation.
If in-kind compensation mitigation is determined not practicable, or unlikely to compensate for the permitted activity, or will be incompatible with the proposed project, and an alternative practicable offsite and out of kind mitigation opportunity is identified that has a greater opportunity for offsetting the permitted impacts (or it is environmentally preferable) – the DE “should require that this alternative mitigation be provided.”
In-kind mitigation is preferable to out-of-kind mitigation because it is most likely to compensate for the functions, services and values of the impacted site. If the DE determines using the watershed approach that out of kind compensatory mitigation will serve the aquatic resource needs of the watershed, the DE may authorize use of such out of kind compensation mitigation.
The amount of compensatory mitigation is to be sufficient to replace lost aquatic resource functions. Where available-functional or condition assessment or other suitable metric methods should be used to determine how much compensation mitigation is required. If such methods are not used, a minimum of one to one acreage or linear foot replacement ratio must be used for mitigation. The DE must require a mitigation ratio greater than one-to-one where necessary to account for the method of compensatory mitigation, the likelihood of success, difference between the functions lost at the impact site and functions expected to be restored by the project, temporary losses or aquatic resources, the difficulty of restoration or establishment of desired aquatic resources, and/or the distance between the affected aquatic resource and the compensation site.
Mitigation banks and in-lieu fee programs can be used to compensate for impacts to aquatic resources authorized by general permit or individual permits.
Preservation may be used to provide compensatory mitigation provided that: the resources provide important physical, chemical, or biological functions for the watershed, the resources contribute significantly to the ecological sustainability of the watershed, and the resources are under threat of destruction or adverse modification. Aquatic resource restoration is to be done in conjunction with preservation to the extent practicable and appropriate.
Buffers may be required by the DE around aquatic resources as well as maintenance of riparian areas around aquatic resources to ensure long term viability of the resources as part of compensation mitigation. If required, there will be credit provided for the establishment and maintenance of riparian areas or upland buffers.
Compensation mitigation may be used in conjunction with other program environmental impacts, such as SMCRA, provided that the project is consistent with the terms and conditions of the program; includes appropriate compensatory mitigation for unavoidable impacts to aquatic resources authorized by the COE permit; and does not use the same credits to provide mitigation for more than one permitted activity.
An individual permit is required to specify the mitigation bank or in-lieu fee program that will be used. A general permit is to identify the specific mitigation bank or in-lieu fee program, or state that the specific mitigation bank or in-lieu fee program is to be approved by the DE before credits are secured. Implementation of the mitigation project is to be in advance of or concurrent with the activity causing the impacts to the maximum extent possible.
Financial assurance must be sufficient to ensure that the compensation mitigation project will be successfully completed in accordance with the applicable performance standards. If financial assurances are required, the permit must include this as a condition to be in place prior to the activity. Financial assurance can be performance bonds, escrow accounts, casualty insurance, letters of credit, legislative appropriations for government sponsored projects, or other instruments approved by the DE. The permit or banking instrument must clearly specify the conditions under which the financial assurances will be released.
Financial assurances are to be phased-out once compensatory mitigation is successful as determined by the DE in accordance with the performance standards.
A project requiring an individual 404 permit must explain how the impacts associated with the activity will be avoided, minimized, and compensated for in the public notice. Activities under a general permit require a compensatory mitigation plan which meets the requirements of the rules, or the DE has the option of addressing requirements as permit conditions. Mitigation plans must contain objective and verifiable performance standards that will be used to assess whether the project is achieving its objectives.
Mitigation plans must identify how monitoring will be conducted, including parameters to be monitored, the length of the monitoring period (not less than 5 years), the party responsible for conducting the monitoring, and for submitting reports, and the frequency for submitting reports.
Documents required to be submitted to the DE include: mitigation plan, objectives, site selection, site protection instrument, baseline information, determination of credits, mitigation work plan, maintenance plan, performance standards, monitoring requirements, long-term management, adaptive management plan, and financial assurance.
All mitigation banks and in-lieu fee programs are to have an approved instrument signed by the sponsor and the DE prior to being used to provide compensatory mitigation. Mitigation banks/in-lieu fee programs are expected to be self-sustaining. An Interagency Review Team (IRT) is established by the DE to facilitate the establishment of mitigation banks or in-lieu fee programs through the appropriate instruments. The team is an advisor to the DE in assessing monitoring, recommending remedial measures, approving credit release, and approving modifications to a banking instrument. The mitigation banking instrument provides the authorization for the mitigation bank to provide credits to be used for compensatory mitigation.
The sponsor is responsible for preparing all documentation: the prospectus, mitigation plan, and the mitigation banking instrument.
Public Review Process: Public notice of the complete prospectus is provided to the public within 30 days by the DE. The comment period for review of the complete prospectus and providing any comments to the Corps is generally 30 days, unless a different period of time is determined appropriate. If the standard permit process is used for the project, then the public notice of the prospectus can be satisfied with the standard permit public notice and comment period (as long as all information is provided as required by the rule).
The DE provides that an initial evaluation within 30 days of whether the proposed mitigation bank or in-lieu fee program will provide compensatory mitigation for the authorized activities and whether the sponsor may proceed with the preparation of the draft instrument.
Draft Mitigation Banking Instrument: A draft is to be prepared for the DE which includes:
- Geographic Service Area of the mitigation bank or in-lieu fee program;
- Accounting procedures;
- Legal responsibility;
- Default and closure provision;
- Reporting protocols; and
- Other information determined necessary by DE
A mitigation bank is required to include in the instrument:
- Credit Release Schedule
- Mitigation plan
An in-lieu fee program is required to include in the instrument:
- The compensation planning framework;
- Initial allocation of advance credits and a draft fee schedule by service area;
- Methodology for determining future project-specific credits and fees; and
- Description of the in-lieu fee program account
DE must inform sponsor of status of interagency review within 90 days of submittal of a complete draft instrument including any concerns which may lead to an objection of the final instrument.
The DE must notify the interagency team within 30 days of his intention to approve or disapprove the instrument. Within 45 days of receipt of the final. If there are no objections from the IRT after 45 days, the DE must notify the sponsor of his dispute decision. Objections are to be addressed through a resolution process.
A stream-lined review process or modification is allowed if determined appropriate by the DE. A single mitigation banking instrument may provide for future authorizations of additional banking sites. The inclusion of additional sites must go through the process of modification.
An in-lieu fee program account must be established at an FDC-member financial institution and can only be used for selection, design, acquisition, implementation and management of the in-lieu fee compensatory mitigation projects with a small percentage for administrative costs.
A COE permit is not be to issued until all relevant provisions of the mitigation banking instrument have been substantially determined. Credit Release Program: Principal units of measure are linear feet or acres and sometimes functional assessment units of particular resource types. Riparian areas, buffers, upland areas and non-aquatic resources can be used as compensatory mitigation only if these resources are determined essential to maintaining the ecological viability of adjoining aquatic resources. A higher mitigation ratio is to be applied to preservation credits based on relative important of the impact and the preserved aquatic resources in sustaining watershed functions.
Process for Release of Credit: Credit releases require approval of the DE through a recommended comment process established in the rule.
If the DE determines that the mitigation bank or in-lieu fee program is not meeting performance standards or complying with the terms of the instrument, the COE DE will take appropriate action such as reducing the number of available credits or suspending credit sales or utilizing financial assurances, and terminating the instrument.
Reporting: The sponsor is required to maintain a ledger to account for all credit transactions for the mitigation bank and notify the DE each time an approved credit transaction occurs.
All mitigation banks approved after July 9, 2008 will be required to meet the requirements of the new rule. Mitigation banks approved prior to July 9, 2008 may continue to operate in accordance with the existing instruments; however, any modification after July 9, 2008 (including authorization of additional sites) must be consistent with the new rule changes.
In-lieu programs operating prior to July 9, 2008 for compensatory mitigation will be permitted to continue to operate under the instruments approved prior to July 9, 2008 until June 9, 2010. After that date, the in-lieu fee program will be required to operate under the new rules unless the DE determines circumstances warrant an extension. Any approved project for which construction was complete under the terms of a previous instrument may continue to operate indefinitely under those terms if the DE determines that the project is providing appropriate mitigation substantially consistent with the new rule.
The most favorable benefit of this regulation is that it leaves inplace an allowance for all types of mitigation, including in-kind and off site out-of-kind mitigation. Unfortunately, the regulation has an expressed preference for mitigation banking. The regulation is anticipated to require an extensive Guidance Document to address many questions left unanswered by this complicated regulation.
