Nationwide Permit 6 Summary
<br />district engineer via telephone, facsimile
<br />transmission, or email that they intend to provide
<br />substantive, site-specific comments. The comments
<br />must explain why the agency believes the adverse
<br />environmental effects will be more than minimal. If
<br />so contacted by an agency, the district engineer will
<br />wait an additional 15 calendar days before making a
<br />decision on the preconstruction notification. The
<br />district engineer will fully consider agency comments
<br />received within the specified time frame concerning
<br />the proposed activity's compliance with the terms
<br />and conditions of the NWPs, including the need for
<br />mitigation to ensure the net adverse environmental
<br />effects of the proposed activity are no more than
<br />minimal. The district engineer will provide no
<br />response to the resource agency, except as provided
<br />below. The district engineer will indicate in the
<br />administrative record associated with each pre -
<br />construction notification that the resource agencies'
<br />concerns were considered. For NWP 37, the
<br />emergency watershed protection and rehabilitation
<br />activity may proceed immediately in cases where
<br />there is an unacceptable hazard to life or a significant
<br />loss of property or economic hardship will occur. The
<br />district engineer will consider any comments
<br />received to decide whether the NWP 37 authorization
<br />should be modified, suspended, or revoked in
<br />accordance with the procedures at 33 CFR 330.5.
<br />❑ (4) In cases of where the prospective permittee
<br />is not a Federal agency, the district engineer will
<br />provide a response to NMFS within 30 calendar days
<br />of receipt of any Essential Fish Habitat conservation
<br />recommendations, as required by section
<br />305(b)(4)(B) of the Magnuson -Stevens Fishery
<br />Conservation and Management Act.
<br />❑ (4) Applicants are encouraged to provide the
<br />Corps with either electronic files or multiple copies
<br />of preconstruction notifications to expedite agency
<br />coordination.
<br />C. District Engineer's Decision
<br />❑ 1. In reviewing the PCN for the proposed activity, the
<br />district engineer will determine whether the activity authorized
<br />by the NWP will result in more than minimal individual or
<br />cumulative adverse environmental effects or may be contrary
<br />to the public interest. If a project proponent requests
<br />authorization by a specific NWP, the district engineer should
<br />issue the NWP verification for that activity if it meets the
<br />terms and conditions of that NWP, unless he or she
<br />determines, after considering mitigation, that the proposed
<br />activity will result in more than minimal individual and
<br />cumulative adverse effects on the aquatic environment and
<br />other aspects of the public interest and exercises discretionary
<br />authority to require an individual permit for the proposed
<br />activity. For a linear project, this determination will include an
<br />evaluation of the individual crossings of waters of the United
<br />States to determine whether they individually satisfy the terms
<br />and conditions of the NWP(s), as well as the cumulative
<br />effects caused by all of the crossings authorized by NWP. If
<br />an applicant requests a waiver of the 300 linear foot limit on
<br />impacts to streams or of an otherwise applicable limit, as
<br />Page 9
<br />provided for in NWPs 13, 21, 29, 36, 39, 40, 42, 43, 44, 50,
<br />51, 52, or 54, the district engineer will only grant the waiver
<br />upon a written determination that the NWP activity will result
<br />in only minimal individual and cumulative adverse
<br />environmental effects. For those NWPs that have a waivable
<br />300 linear foot limit for losses of intermittent and ephemeral
<br />stream bed and a 12 -acre limit (i.e., NWPs 21, 29, 39, 40, 42,
<br />43, 44, 50, 51, and 52), the loss of intermittent and ephemeral
<br />stream bed, plus any other losses of jurisdictional waters and
<br />wetlands, cannot exceed 12- acre.
<br />❑ 2. When making minimal adverse environmental effects
<br />determinations the district engineer will consider the direct
<br />and indirect effects caused by the NWP activity. He or she
<br />will also consider the cumulative adverse environmental
<br />effects caused by activities authorized by NWP and whether
<br />those cumulative adverse environmental effects are no more
<br />than minimal. The district engineer will also consider site
<br />specific factors, such as the environmental setting in the
<br />vicinity of the NWP activity, the type of resource that will be
<br />affected by the NWP activity, the functions provided by the
<br />aquatic resources that will be affected by the NWP activity,
<br />the degree or magnitude to which the aquatic resources
<br />perform those functions, the extent that aquatic resource
<br />functions will be lost as a result of the NWP activity (e.g.,
<br />partial or complete loss), the duration of the adverse effects
<br />(temporary or permanent), the importance of the aquatic
<br />resource functions to the region (e.g., watershed or ecoregion),
<br />and mitigation required by the district engineer. If an
<br />appropriate functional or condition assessment method is
<br />available and practicable to use, that assessment method may
<br />be used by the district engineer to assist in the minimal
<br />adverse environmental effects determination. The district
<br />engineer may add case -specific special conditions to the NWP
<br />authorization to address site-specific environmental concerns.
<br />❑ 3. If the proposed activity requires a PCN and will
<br />result in a loss of greater than IA10-acre of wetlands, the
<br />prospective permittee should submit a mitigation proposal
<br />with the PCN. Applicants may also propose compensatory
<br />mitigation for NWP activities with smaller impacts, or for
<br />impacts to other types of waters (e.g., streams). The district
<br />engineer will consider any proposed compensatory mitigation
<br />or other mitigation measures the applicant has included in the
<br />proposal in determining whether the net adverse
<br />environmental effects of the proposed activity are no more
<br />than minimal. The compensatory mitigation proposal may be
<br />either conceptual or detailed. If the district engineer
<br />determines that the activity complies with the terms and
<br />conditions of the NWP and that the adverse environmental
<br />effects are no more than minimal, after considering mitigation,
<br />the district engineer will notify the permittee and include any
<br />activity -specific conditions in the NWP verification the district
<br />engineer deems necessary. Conditions for compensatory
<br />mitigation requirements must comply with the appropriate
<br />provisions at 33 CFR 332.3(k). The district engineer must
<br />approve the final mitigation plan before the permittee
<br />commences work in waters of the United States, unless the
<br />district engineer determines that prior approval of the final
<br />mitigation plan is not practicable or not necessary to ensure
<br />timely completion of the required compensatory mitigation. If
<br />the prospective permittee elects to submit a compensatory
<br />mitigation plan with the PCN, the district engineer will
