FINAL NOTICE OF ISSUANCE AND MODIFICATION OF NATIONWIDE PERMITS
FEDERAL REGISTER
AUTHORIZED MARCH 19, 2012
Bank Stabilization. Bank stabilization activities necessary for erosion prevention,
provided the activity meets all of the following criteria:
(a) No material is placed in excess of the minimum needed far erosion protection;
(b) The activity is no more than 500 feet in length along the bank, unless the district
engineer waives this criterion by making a written determination concluding that the discharge
will result in minimal adverse effects;
(c) The activity will not exceed an average of one cubic yard per running foot placed
along the bank below the plane of the ordinary high water mark or the high tide line, unless the
district engineer waives this criterion by making a written determination concluding that the
discharge will result in minimal adverse effects;
(d) The activity does not involve discharges of dredged or fill material into special
aquatic sites, unless the district engineer waives this criterion by making a written determination
concluding that the discharge will result in minimal adverse effects;
(e) No material is of a type, or is placed in any location, or in any manner, that will impair
surface water flow into or out of any waters of the United States;
(� No material is placed in a manner that will be eroded by normal or expected high
flows (properly anchored trees and treetops may be used in low energy areas); and,
(g) The activity is not a stream channelization activity.
This NWP also authorizes temporary structures, fills, and work necessary to construct the
bank stabilization activity. Appropriate measures must be taken to maintain normal downstream
flows and minimize flooding to the maximum extent practicable, when temporary structures,
work, and discharges, including cofferdams, are necessary for construction activities, access fills,
or dewatering of construction sites. Temporary fills must consist of materials, and be placed in a
manner, that will not be eroded by expected high flows. Temporary fills must be removed in
their entirety and the affected areas returned to pre-construction elevations. The areas affected by
temporary fills must be revegetated, as appropriate.
Invasive plant species shall not be used for bioengineering or vegetative bank
stabilization.
Notification: The permittee must submit a pre-construction notification to the district
engineer prior to commencing the activity if the bank stabilization activity: (1) involves
discharges into special aquatic sites; or (2) is in excess of 500 feet in length; or (3) will involve
the discharge of greater than an average of one cubic yard per running foot along the bank below
the plane of the ordinary high water mark or the high tide line. (See general condition 31.)
(Sections 10 and 404)

NATIONWIDE PERMIT CONDITIONS
The following General Conditions must be followed in order for any authorization by a NWP to
be valid:
1. Navi ag tion. (a) No activity may cause more than a minimal adverse effect on
navigation.
(b) Any safety lights and signals prescribed by the U.S. Coast Guard, through regulations
or otherwise, must be installed and maintained at the permittee's expense on authorized facilities
in navigable waters of the United States.
(c) The permittee understands and agrees that, if future operations by the United States
require the removal, relocation, or other alteration, of the structure or work herein authorized, or
if, in the opinion of the Secretary of the Army ar his authorized representative, said structure ar
work shall cause unreasonable obstruction to the free navigation of the navigable waters, the
permittee will be required, upon due notice from the Corps of Engineers, to remove, relocate, or
alter the structural work or obstructions caused thereby, without expense to the United States. No
claim shall be made against the United States on account of any such removal or alteration.
2. Aquatic Life Movements. No activity may substantially disrupt the necessary life cycle
movements of those species of aquatic life indigenous to the waterbody, including those species
that normally migrate through the area, unless the activity's primary purpose is to impound
water. All permanent and temporary crossings of waterbodies shall be suitably culverted,
bridged, or otherwise designed and constructed to maintain low flows to sustain the movement of
those aquatic species.
3. �awning, Areas. Activities in spawning areas during spawning seasons must be
avoided to the maximum extent practicable. Activities that result in the physical destruction (e.g.,
through excavation, fill, or downstream smothering by substantial turbidity) of an important
spawning area are not authorized.
4. Migratorv Bird Breeding Areas. Activities in waters of the United States that serve as
breeding areas for migratory birds must be avoided to the maximum extent practicable.
5. Shellfish Beds. No activity may occur in areas of concentrated shellfish populations,
unless the activity is directly related to a shellfish harvesting activity authorized by NWPs 4 and
48, or is a shellfish seeding or habitat restoration activity authorized by N WP 27.
6. Suitable Material. No activity may use unsuitable material (e.g., trash, debris, car
bodies, asphalt, etc.). Material used for construction or discharged must be free from toxic
pollutants in toxic amounts (see Section 307 of the Clean Water Act).
7. Water Su�lv Intakes. No activity may occur in the proximity of a public water supply
intake, except where the activity is for the repair or improvement of public water supply intake
structures or adjacent bank stabilization.
2

8. Adverse Effects From Impoundments. If the activity creates an impoundment of water,
adverse effects to the aquatic system due to accelerating the passage of water, and/or restricting
its flow must be minimized to the maximum extent practicable.
9. Mana�ement of Water Flows. To the maximum extent practicable, the pre-construction
course, condition, capacity, and location of open waters must be maintained for each activity,
including stream channelization and storm water management activities, except as provided
below. The activity must be constructed to withstand expected high flows. The activity must not
restrict or impede the passage of normal or high flows, unless the primary purpose of the activity
is to impound water or manage high flows. The activity may alter the pre-construction course,
condition, capacity, and location of open waters if it benefits the aquatic environment (e.g.,
stream restoration or relocation activities).
10. Fills Within 100-Year Floodplains. The activity must comply with applicable FEMA-
approved state or local floodplain management requirements.
11. Equipment. Heavy equipment working in wetlands or mudflats must be placed on
mats, or other measures must be taken to minimize soil disturbance.
12. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls
must be used and maintained in effective operating condition during construction, and all
exposed soil and other fills, as well as any work below the ordinary high water mark or high tide
line, must be permanently stabilized at the earliest practicable date. Permittees are encouraged to
perform work within waters of the United States during periods of low-flow or no-flow.
13. Removal of Tempora .r�Fills. Temporary fills must be removed in their entirety and
the affected areas returned to pre-construction elevations. The affected areas must be
revegetated, as appropriate.
14. Proper Maintenance. Any authorized structure or fill shall be properly maintained,
including maintenance to ensure public safety and compliance with applicable NWP general
conditions, as well as any activity-specific conditions added by the district engineer to an NWP
authorization.
15. Single and Complete Project. The activity must be a single and complete project. The
same NWP cannot be used more than once for the same single and complete project.
16. Wild and Scenic Rivers. No activity may occur in a component of the National Wild
and Scenic River System, or in a river officially designated by Congress as a"study river" for
possible inclusion in the system while the river is in an official study status, unless the
appropriate Federal agency with direct management responsibility for such river, has determined
in writing that the proposed activity will not adversely affect the Wild and Scenic River
designation or study status. Information on Wild and Scenic Rivers may be obtained from the
appropriate Federal land management agency responsible for the designated Wild and Scenic
River or study river (e.g., National Park Service, U.S. Forest Service, Bureau of Land
Management, U.S. Fish and Wildlife Service).

17. Tribal Ri _�. No activity or its operation may impair reserved tribal rights, including,
but not limited to, reserved water rights and treaty fishing and hunting rights.
18. Endangered Species. (a) No activity is authorized under any NWP which is likely to
directly or indirectly jeopardize the continued existence of a threatened or endangered species or
a species proposed for such designation, as identified under the Federal Endangered Species Act
(ESA), or which will directly or indirectly destroy or adversely modify the critical habitat of such
species. No activity is autharized under any NWP which "may affect" a listed species ar critical
habitat, unless Section 7 consultation addressing the effects of the proposed activity has been
completed.
(b) Federal agencies should follow their own procedures for complying with the
requirements of the ESA. Federal permittees must provide the district engineer with the
appropriate documentation to demonstrate compliance with those requirements. The district
engineer will review the documentation and determine whether it is sufficient to address ESA
compliance for the NWP activity, or whether additional ESA consultation is necessary.
(c) Non-federal permittees must submit a pre-construction notification to the district
engineer if any listed species or designated critical habitat might be affected or is in the vicinity
of the project, or if the project is located in designated critical habitat, and shall not begin work
on the activity until notified by the district engineer that the requirements of the ESA have been
satisfied and that the activity is autharized. For activities that might affect Federally-listed
endangered or threatened species or designated critical habitat, the pre-construction notification
must include the name(s) of the endangered or threatened species that might be affected by the
proposed work or that utilize the designated critical habitat that might be affected by the
proposed work. The district engineer will determine whether the proposed activity "may affect"
or will have "no effect" to listed species and designated critical habitat and will notify the non-
Federal applicant of the Corps' determination within 45 days of receipt of a complete pre-
construction notification. In cases where the non-Federal applicant has identified listed species or
critical habitat that might be affected or is in the vicinity of the project, and has so notified the
Corps, the applicant shall not begin work until the Corps has provided notification the proposed
activities will have "no effect" on listed species or critical habitat, or until Section 7 consultation
has been completed. If the non-Federal applicant has not heard back from the Corps within 45
days, the applicant must still wait for notification from the Corps.
(d) As a result of formal or informal consultation with the FWS or NMFS the district
engineer may add species-specific regional endangered species conditions to the NWPs.
(e) Authorization of an activity by a NWP does not authorize the "take" of a threatened or
endangered species as defined under the ESA. In the absence of separate authorization (e.g., an
ESA Section 10 Permit, a Biological Opinion with "incidental take" provisions, etc.) from the
U.S. FWS or the NMFS, The Endangered Species Act prohibits any person subject to the
jurisdiction of the United States to take a listed species, where "take" means to harass, harm,
pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such
conduct. The word "harm" in the definition of "take" means an act which actually kills or injures
wildlife. Such an act may include significant habitat modification or degradation where it
actually kills or injures wildlife by significantly impairing essential behavioral patterns,
including breeding, feeding or sheltering.
�

(� Information on the location of threatened and endangered species and their critical
habitat can be obtained directly from the offices of the U.S. FWS and NMFS or their world wide
web pages at http://www.fws.gov/ or http://www.fws.gov/ipac and
http://www.noaa.gov/fisheries.html respectively.
19. Mi r� atory Birds and Bald and Golden Eagles. The permittee is responsible for
obtaining any "take" permits required under the U.S. Fish and Wildlife Service's regulations
governing compliance with the Migratory Bird Treaty Act or the Bald and Golden Eagle
Protection Act. The permittee should contact the appropriate local office of the U.S. Fish and
Wildlife Service to determine if such "take" permits are required for a particular activity.
20. Historic Properties. (a) In cases where the district engineer determines that the
activity may affect properties listed, or eligible far listing, in the National Register of Historic
Places, the activity is not authorized, until the requirements of Section 106 of the National
Historic Preservation Act (NHPA) have been satisfied.
(b) Federal permittees should follow their own procedures for complying with the
requirements of Section 106 of the National Historic Preservation Act. Federal permittees must
provide the district engineer with the appropriate documentation to demonstrate compliance with
those requirements. The district engineer will review the documentation and determine whether
it is sufficient to address section 106 compliance for the NWP activity, or whether additional
section 106 consultation is necessary.
(c) Non-federal permittees must submit a pre-construction notification to the district
engineer if the authorized activity may have the potential to cause effects to any historic
properties listed on, determined to be eligible for listing on, or potentially eligible for listing on
the National Register of Historic Places, including previously unidentified properties. For such
activities, the pre-construction notification must state which historic properties may be affected
by the proposed work or include a vicinity map indicating the location of the historic properties
or the potential for the presence of historic properties. Assistance regarding information on the
location of or potential for the presence of historic resources can be sought from the State
Historic Preservation Officer or Tribal Historic Preservation Officer, as appropriate, and the
National Register of Historic Places (see 33 CFR 330.4(g)). When reviewing pre-construction
notifications, district engineers will comply with the current procedures for addressing the
requirements of Section 106 of the National Historic Preservation Act. The district engineer shall
make a reasonable and good faith effort to carry out appropriate identification efforts, which may
include background research, consultation, oral history interviews, sample field investigation,
and field survey. Based on the information submitted and these efforts, the district engineer shall
determine whether the proposed activity has the potential to cause an effect on the historic
properties. Where the non-Federal applicant has identified historic properties on which the
activity may have the potential to cause effects and so notified the Corps, the non-Federal
applicant shall not begin the activity until notified by the district engineer either that the activity
has no potential to cause effects or that consultation under Section 106 of the NHPA has been
completed.
(d) The district engineer will notify the prospective permittee within 45 days of receipt
of a complete pre-construction notification whether NHPA Section 106 consultation is required.
Section 106 consultation is not required when the Corps determines that the activity does not
have the potential to cause effects on historic properties (see 36 CFR §800.3(a)). If NHPA
5

section 106 consultation is required and will occur, the district engineer will notify the non-
Federal applicant that he or she cannot begin work until Section 106 consultation is completed. If
the non-Federal applicant has not heard back from the Corps within 45 days, the applicant must
still wait for notification from the Corps.
(e) Prospective permittees should be aware that section 110k of the NHPA (16 U.S.C.
470h-2(k)) prevents the Corps from granting a permit or other assistance to an applicant who,
with intent to avoid the requirements of Section 106 of the NHPA, has intentionally significantly
adversely affected a historic property to which the permit would relate, or having legal power to
prevent it, allowed such significant adverse effect to occur, unless the Corps, after consultation
with the Advisory Council on Historic Preservation (ACHP), determines that circumstances
justify granting such assistance despite the adverse effect created or permitted by the applicant.
If circumstances justify granting the assistance, the Corps is required to notify the ACHP and
provide documentation specifying the circumstances, the degree of damage to the integrity of
any historic properties affected, and proposed mitigation. This documentation must include any
views obtained from the applicant, SHPO/THPO, appropriate Indian tribes if the undertaking
occurs on or affects historic properties on tribal lands or affects properties of interest to those
tribes, and other parties known to have a legitimate interest in the impacts to the permitted
activity on historic properties.
21. Discovery of Previously Unknown Remains and Artifacts. If you discover any
previously unknown historic, cultural or archeological remains and artifacts while accomplishing
the activity authorized by this permit, you must immediately notify the district engineer of what
you have found, and to the maximum extent practicable, avoid construction activities that may
affect the remains and artifacts until the required coordination has been completed. The district
engineer will initiate the Federal, Tribal and state coordination required to determine if the items
or remains warrant a recovery effort or if the site is eligible for listing in the National Register of
Historic Places.
22. Designated Critical Resource Waters. Critical resource waters include, NOAA-
managed marine sanctuaries and marine monuments, and National Estuarine Research Reserves.
The district engineer may designate, after notice and opportunity for public comment, additional
waters officially designated by a state as having particular environmental or ecological
significance, such as outstanding national resource waters or state natural heritage sites. The
district engineer may also designate additional critical resource waters after notice and
opportunity for public comment.
(a) Discharges of dredged or fill material into waters of the United States are not
authorized by NWPs 7, 12, 14, 16, 17, 21, 29, 31, 35, 39, 40, 42, 43, 44, 49, 50, 51, and 52 for
any activity within, or directly affecting, critical resource waters, including wetlands adjacent to
such waters.
(b) For NWPs 3, 8, 10, 13, 15, 18, 19, 22, 23, 25, 27, 28, 30, 33, 34, 36, 37, and 38,
notification is required in accordance with general condition 31, for any activity proposed in the
designated critical resource waters including wetlands adjacent to those waters. The district
engineer may authorize activities under these NWPs only after it is determined that the impacts
to the critical resource waters will be no more than minimal.
0

23. Miti ation. The district engineer will consider the following factors when
determining appropriate and practicable mitigation necessary to ensure that adverse effects on
the aquatic environment are minimal:
(a) The activity must be designed and constructed to avoid and minimize adverse effects,
both temporary and permanent, to waters of the United States to the maximum extent practicable
at the project site (i.e., on site).
(b) Mitigation in all its forms (avoiding, minimizing, rectifying, reducing, or
compensating for resource losses) will be required to the extent necessary to ensure that the
adverse effects to the aquatic environment are minimal.
(c) Compensatory mitigation at a minimum one-for-one ratio will be required for all
wetland losses that exceed 1/10-acre and require pre-construction notification, unless the district
engineer determines in writing that either some other form of mitigation would be more
environmentally appropriate or the adverse effects of the proposed activity are minimal, and
provides a project-specific waiver of this requirement. For wetland losses of 1/10-acre or less
that require pre-construction notification, the district engineer may determine on a case-by-case
basis that compensatory mitigation is required to ensure that the activity results in minimal
adverse effects on the aquatic environment. Compensatory mitigation projects provided to offset
losses of aquatic resources must comply with the applicable provisions of 33 CFR part 332.
(1) The prospective permittee is responsible for proposing an appropriate compensatory
mitigation option if compensatory mitigation is necessary to ensure that the activity results in
minimal adverse effects on the aquatic environment.
(2) Since the likelihood of success is greater and the impacts to potentially valuable
uplands are reduced, wetland restoration should be the first compensatory mitigation option
considered.
(3) If permittee-responsible mitigation is the proposed option, the prospective permittee is
responsible for submitting a mitigation plan. A conceptual or detailed mitigation plan may be
used by the district engineer to make the decision on the NWP verification request, but a final
mitigation plan that addresses the applicable requirements of 33 CFR 332.4(c)(2) —(14) must be
approved by the district engineer before the permittee begins work in waters of the United States,
unless the district engineer determines that prior approval of the final mitigation plan is not
practicable or not necessary to ensure timely completion of the required compensatory mitigation
(see 33 CFR 332.3(k)(3)).
(4) If mitigation bank or in-lieu fee program credits are the proposed option, the
mitigation plan only needs to address the baseline conditions at the impact site and the number of
credits to be provided.
(5) Compensatory mitigation requirements (e.g., resource type and amount to be provided
as compensatory mitigation, site protection, ecological performance standards, monitoring
requirements) may be addressed through conditions added to the NWP authorization, instead of
components of a compensatory mitigation plan.
(d) For losses of streams or other open waters that require pre-construction notification,
the district engineer may require compensatory mitigation, such as stream rehabilitation,
enhancement, or preservation, to ensure that the activity results in minimal adverse effects on the
aquatic environment.
(e) Compensatory mitigation will not be used to increase the acreage losses allowed by
the acreage limits of the NWPs. For example, if an NWP has an acreage limit of 1/2-acre, it
cannot be used to authorize any project resulting in the loss of greater than 1/2-acre of waters of
7

the United States, even if compensatory mitigation is provided that replaces or restores some of
the lost waters. However, compensatory mitigation can and should be used, as necessary, to
ensure that a project already meeting the established acreage limits also satisfes the minimal
impact requirement associated with the NWPs.
(� Compensatory mitigation plans for projects in or near streams or other open waters
will normally include a requirement for the restoration or establishment, maintenance, and legal
protection (e.g., conservation easements) of riparian areas next to open waters. In some cases,
riparian areas may be the only compensatory mitigation required. Riparian areas should consist
of native species. The width of the required riparian area will address documented water quality
or aquatic habitat loss concerns. Normally, the riparian area will be 25 to 50 feet wide on each
side of the stream, but the district engineer may require slightly wider riparian areas to address
documented water quality or habitat loss concerns. If it is not possible to establish a riparian area
on both sides of a stream, or if the waterbody is a lake or coastal waters, then restoring or
establishing a riparian area along a single bank or shoreline may be sufficient. Where both
wetlands and open waters exist on the project site, the district engineer will determine the
appropriate compensatory mitigation (e.g., riparian areas and/or wetlands compensation) based
on what is best for the aquatic environment on a watershed basis. In cases where riparian areas
are determined to be the most appropriate form of compensatory mitigation, the district engineer
may waive or reduce the requirement to provide wetland compensatory mitigation for wetland
losses.
(g) Permittees may propose the use of mitigation banks, in-lieu fee programs, or separate
permittee-responsible mitigation. For activities resulting in the loss of marine or estuarine
resources, permittee-responsible compensatory mitigation may be environmentally preferable if
there are no mitigation banks or in-lieu fee programs in the area that have marine or estuarine
credits available for sale or transfer to the permittee. For permittee-responsible mitigation, the
special conditions of the NWP verification must clearly indicate the party or parties responsible
for the implementation and performance of the compensatory mitigation project, and, if required,
its long-term management.
(h) Where certain functions and services of waters of the United States are permanently
adversely affected, such as the conversion of a forested or scrub-shrub wetland to a herbaceous
wetland in a permanently maintained utility line right-of-way, mitigation may be required to
reduce the adverse effects of the project to the minimal level.
24. Safety of Impoundment Structures. To ensure that all impoundment structures are
safely designed, the district engineer may require non-Federal applicants to demonstrate that the
structures comply with established state dam safety criteria or have been designed by qualified
persons. The district engineer may also require documentation that the design has been
independently reviewed by similarly qualified persons, and appropriate modifications made to
ensure safety.
25. Water Qualitv. Where States and authorized Tribes, or EPA where applicable, have
not previously certified compliance of an NWP with CWA Section 401, individua1401 Water
Quality Certification must be obtained or waived (see 33 CFR 330.4(c)). The district engineer or
State or Tribe may require additional water quality management measures to ensure that the
authorized activity does not result in more than minimal degradation of water quality.
:

26. Coastal Zone Mana eg ment. In coastal states where an NWP has not previously
received a state coastal zone management consistency concurrence, an individual state coastal
zone management consistency concurrence must be obtained, or a presumption of concurrence
must occur (see 33 CFR 330.4(d)). The district engineer or a State may require additional
measures to ensure that the authorized activity is consistent with state coastal zone management
requirements.
27. Re�ional and Case-By-Case Conditions. The activity must comply with any regional
conditions that may have been added by the Division Engineer (see 33 CFR 330.4(e)) and with
any case specific conditions added by the Corps or by the state, Indian Tribe, or U.S. EPA in its
section 401 Water Quality Certification, or by the state in its Coastal Zone Management Act
consistency determination.
28. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and
complete proj ect is prohibited, except when the acreage loss of waters of the United States
authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified
acreage limit. For example, if a road crossing over tidal waters is constructed under NWP 14,
with associated bank stabilization authorized by NWP 13, the maximum acreage loss of waters
of the United States for the total project cannot exceed 1/3-acre.
29. Transfer of Nationwide Permit Veriiications. If the permittee sells the property
associated with a nationwide permit verification, the permittee may transfer the nationwide
permit verification to the new owner by submitting a letter to the appropriate Corps district office
to validate the transfer. A copy of the nationwide permit verification must be attached to the
letter, and the letter must contain the following statement and signature:
"When the structures or work authorized by this nationwide permit are still in existence at
the time the property is transferred, the terms and conditions of this nationwide permit, including
any special conditions, will continue to be binding on the new owner(s) of the property. To
validate the transfer of this nationwide permit and the associated liabilities associated with
compliance with its terms and conditions, have the transferee sign and date below."
(Transferee)
(Date)
30. Compliance Certification. Each permittee who receives an NWP verification letter
from the Corps must provide a signed certification documenting completion of the authorized
activity and any required compensatory mitigation. The success of any required permittee-
responsible mitigation, including the achievement of ecological performance standards, will be
addressed separately by the district engineer. The Corps will provide the permittee the
certification document with the NWP verification letter. The certification document will
include:
0

(a) A statement that the authorized work was done in accordance with the NWP
authorization, including any general, regional, or activity-specific conditions;
(b) A statement that the implementation of any required compensatory mitigation was
completed in accordance with the permit conditions. If credits from a mitigation bank or in-lieu
fee program are used to satisfy the compensatory mitigation requirements, the certification must
include the documentation required by 33 CFR 332.3(1)(3) to confirm that the permittee secured
the appropriate number and resource type of credits; and
(c) The signature of the permittee certifying the completion of the work and mitigation.
31. Pre-Construction Notification. (a) Timin�. Where required by the terms of the NWP,
the prospective permittee must notify the district engineer by submitting a pre-construction
notification (PCN) as early as possible. The district engineer must determine if the PCN is
complete within 30 calendar days of the date of receipt and, if the PCN is determined to be
incomplete, notify the prospective permittee within that 30 day period to request the additional
information necessary to make the PCN complete. The request must specify the information
needed to make the PCN complete. As a general rule, district engineers will request additional
information necessary to make the PCN complete only once. However, if the prospective
permittee does not provide all of the requested information, then the district engineer will notify
the prospective permittee that the PCN is still incomplete and the PCN review process will not
commence until all of the requested information has been received by the district engineer. The
prospective permittee shall not begin the activity until either:
(1) He or she is notified in writing by the district engineer that the activity may proceed
under the NWP with any special conditions imposed by the district or division engineer; or
(2) 45 calendar days have passed from the district engineer's receipt of the complete PCN
and the prospective permittee has not received written notice from the district or division
engineer. However, if the permittee was required to notify the Corps pursuant to general
condition 18 that listed species or critical habitat might be affected or in the vicinity of the
project, or to notify the Corps pursuant to general condition 20 that the activity may have the
potential to cause effects to historic properties, the permittee cannot begin the activity until
receiving written notification from the Corps that there is "no effect" on listed species or "no
potential to cause effects" on historic properties, or that any consultation required under Section
7 of the Endangered Species Act (see 33 CFR 330.4(�) and/or Section 106 of the National
Historic Preservation (see 33 CFR 330.4(g)) has been completed. Also, work cannot begin under
NWPs 21, 49, or 50 until the permittee has received written approval from the Corps. If the
proposed activity requires a written waiver to exceed specified limits of an NWP, the permittee
may not begin the activity until the district engineer issues the waiver. If the district or division
engineer notifies the permittee in writing that an individual permit is required within 45 calendar
days of receipt of a complete PCN, the permittee cannot begin the activity until an individual
permit has been obtained. Subsequently, the permittee's right to proceed under the NWP may be
modified, suspended, or revoked only in accordance with the procedure set forth in 33 CFR
330.5(d)(2).
(b) Contents of Pre-Construction Notification: The PCN must be in writing and include
the following information:
(1) Name, address and telephone numbers of the prospective permittee;
(2) Location of the proposed project;
10

(3) A description of the proposed project; the project's purpose; direct and indirect
adverse environmental effects the project would cause, including the anticipated amount of loss
of water of the United States expected to result from the NWP activity, in acres, linear feet, or
other appropriate unit of ineasure; any other N WP(s), regional general permit(s), or individual
permit(s) used or intended to be used to authorize any part of the proposed project or any related
activity. The description should be sufficiently detailed to allow the district engineer to
determine that the adverse effects of the project will be minimal and to determine the need far
compensatory mitigation. Sketches should be provided when necessary to show that the activity
complies with the terms of the NWP. (Sketches usually clarify the project and when provided
results in a quicker decision. Sketches should contain sufficient detail to provide an illustrative
description of the proposed activity (e.g., a conceptual plan), but do not need to be detailed
engineering plans);
(4) The PCN must include a delineation of wetlands, other special aquatic sites, and other
waters, such as lakes and ponds, and perennial, intermittent, and ephemeral streams, on the
project site. Wetland delineations must be prepared in accordance with the current method
required by the Corps. The permittee may ask the Corps to delineate the special aquatic sites and
other waters on the project site, but there may be a delay if the Corps does the delineation,
especially if the project site is large or contains many waters of the United States. Furthermore,
the 45 day period will not start until the delineation has been submitted to or completed by the
Corps, as appropriate;
(5) If the proposed activity will result in the loss of greater than 1/10-acre of wetlands and
a PCN is required, the prospective permittee must submit a statement describing how the
mitigation requirement will be satisfied, or explaining why the adverse effects are minimal and
why compensatory mitigation should not be required. As an alternative, the prospective
permittee may submit a conceptual or detailed mitigation plan.
(6) If any listed species or designated critical habitat might be affected or is in the vicinity
of the project, or if the project is located in designated critical habitat, for non-Federal applicants
the PCN must include the name(s) of those endangered or threatened species that might be
affected by the proposed work or utilize the designated critical habitat that may be affected by
the proposed work. Federal applicants must provide documentation demonstrating compliance
with the Endangered Species Act; and
(7) For an activity that may affect a historic property listed on, determined to be eligible
for listing on, or potentially eligible for listing on, the National Register of Historic Places, for
non-Federal applicants the PCN must state which historic property may be affected by the
proposed work or include a vicinity map indicating the location of the historic property. Federal
applicants must provide documentation demonstrating compliance with Section 106 of the
National Historic Preservation Act.
(c) Form of Pre-Construction Notification: The standard individual permit application
form (Form ENG 4345) may be used, but the completed application form must clearly indicate
that it is a PCN and must include all of the information required in paragraphs (b)(1) through (7)
of this general condition. A letter containing the required information may also be used.
(d) A�ency Coordination: (1) The district engineer will consider any comments from
Federal and state agencies concerning the proposed activity's compliance with the terms and
conditions of the NWPs and the need for mitigation to reduce the project's adverse
environmental effects to a minimal level.
11

(2) For all NWP activities that require pre-construction notification and result in the loss
of greater than 1/2-acre of waters of the United States, for NWP 21, 29, 39, 40, 42, 43, 44, 50,
51, and 52 activities that require pre-construction notification and will result in the loss of greater
than 3001inear feet of intermittent and ephemeral stream bed, and for all N WP 48 activities that
require pre-construction notification, the district engineer will immediately provide (e.g., via e-
mail, facsimile transmission, overnight mail, or other expeditious manner) a copy of the
complete PCN to the appropriate Federal or state offices (U.S. FWS, state natural resource or
water quality agency, EPA, State Historic Preservation Officer (SHPO) or Tribal Historic
Preservation Office (THPO), and, if appropriate, the NMFS). With the exception of NWP 37,
these agencies will have 10 calendar days from the date the material is transmitted to telephone
or fax the district engineer notice that they intend to provide substantive, site-specific comments.
The comments must explain why the agency believes the adverse effects will be more than
minimal. If so contacted by an agency, the district engineer will wait an additional 15 calendar
days before making a decision on the pre-construction notification. The district engineer will
fully consider agency comments received within the specified time frame concerning the
proposed activity's compliance with the terms and conditions of the NWPs, including the need
for mitigation to ensure the net adverse environmental effects to the aquatic environment of the
proposed activity are minimal. The district engineer will provide no response to the resource
agency, except as provided below. The district engineer will indicate in the administrative record
associated with each pre-construction notification that the resource agencies' concerns were
considered. For NWP 37, the emergency watershed protection and rehabilitation activity may
proceed immediately in cases where there is an unacceptable hazard to life or a significant loss of
property or economic hardship will occur. The district engineer will consider any comments
received to decide whether the NWP 37 authorization should be modified, suspended, or revoked
in accordance with the procedures at 33 CFR 330.5.
(3) In cases of where the prospective permittee is not a Federal agency, the district
engineer will provide a response to NMFS within 30 calendar days of receipt of any Essential
Fish Habitat conservation recommendations, as required by Section 305(b)(4)(B) of the
Magnuson-Stevens Fishery Conservation and Management Act.
(4) Applicants are encouraged to provide the Corps with either electronic files or multiple
copies of pre-construction notifications to expedite agency coordination.
D. District En�ineer's Decision
1. In reviewing the PCN for the proposed activity, the district engineer will determine
whether the activity authorized by the NWP will result in more than minimal individual or
cumulative adverse environmental effects or may be contrary to the public interest. For a linear
project, this determination will include an evaluation of the individual crossings to determine
whether they individually satisfy the terms and conditions of the NWP(s), as well as the
cumulative effects caused by all of the crossings authorized by NWP. If an applicant requests a
waiver of the 3001inear foot limit on impacts to intermittent or ephemeral streams or of an
otherwise applicable limit, as provided for in NWPs 13, 21, 29, 36, 39, 40, 42, 43, 44, 50, 51 or
52, the district engineer will only grant the waiver upon a written determination that the NWP
activity will result in minimal adverse effects. When making minimal effects determinations the
district engineer will consider the direct and indirect effects caused by the NWP activity. The
district engineer will also consider site specific factors, such as the environmental setting in the
12

vicinity of the NWP activity, the type of resource that will be affected by the NWP activity, the
functions provided by the aquatic resources that will be affected by the NWP activity, the degree
or magnitude to which the aquatic resources perform those functions, the extent that aquatic
resource functions will be lost as a result of the NWP activity (e.g., partial or complete loss), the
duration of the adverse effects (temporary or permanent), the importance of the aquatic resource
functions to the region (e.g., watershed or ecoregion), and mitigation required by the district
engineer. If an appropriate functional assessment method is available and practicable to use, that
assessment method may be used by the district engineer to assist in the minimal adverse effects
determination. The district engineer may add case-specific special conditions to the NWP
authorization to address site-specific environmental concerns.
2. If the proposed activity requires a PCN and will result in a loss of greater than 1/10-
acre of wetlands, the prospective permittee should submit a mitigation proposal with the PCN.
Applicants may also propose compensatory mitigation for projects with smaller impacts. The
district engineer will consider any proposed compensatory mitigation the applicant has included
in the proposal in determining whether the net adverse environmental effects to the aquatic
environment of the proposed activity are minimal. The compensatory mitigation proposal may be
either conceptual or detailed. If the district engineer determines that the activity complies with
the terms and conditions of the NWP and that the adverse effects on the aquatic environment are
minimal, after considering mitigation, the district engineer will notify the permittee and include
any activity-specific conditions in the NWP verification the district engineer deems necessary.
Conditions for compensatory mitigation requirements must comply with the appropriate
provisions at 33 CFR 332.3(k). The district engineer must approve the final mitigation plan
before the permittee commences work in waters of the United States, unless the district engineer
determines that prior approval of the final mitigation plan is not practicable or not necessary to
ensure timely completion of the required compensatory mitigation. If the prospective permittee
elects to submit a compensatory mitigation plan with the PCN, the district engineer will
expeditiously review the proposed compensatory mitigation plan. The district engineer must
review the proposed compensatory mitigation plan within 45 calendar days of receiving a
complete PCN and determine whether the proposed mitigation would ensure no more than
minimal adverse effects on the aquatic environment. If the net adverse effects of the project on
the aquatic environment (after consideration of the compensatory mitigation proposal) are
determined by the district engineer to be minimal, the district engineer will provide a timely
written response to the applicant. The response will state that the project can proceed under the
terms and conditions of the NWP, including any activity-specific conditions added to the NWP
authorization by the district engineer.
3. If the district engineer determines that the adverse effects of the proposed work are
more than minimal, then the district engineer will notify the applicant either: (a) That the project
does not qualify for authorization under the NWP and instruct the applicant on the procedures to
seek authorization under an individual permit; (b) that the project is authorized under the NWP
subject to the applicant's submission of a mitigation plan that would reduce the adverse effects
on the aquatic environment to the minimal level; or (c) that the project is authorized under the
NWP with specific modiiications or conditions. Where the district engineer determines that
mitigation is required to ensure no more than minimal adverse effects occur to the aquatic
environment, the activity will be authorized within the 45-day PCN period, with activity-specific
13

conditions that state the mitigation requirements. The authorization will include the necessary
conceptual or detailed mitigation or a requirement that the applicant submit a mitigation plan that
would reduce the adverse effects on the aquatic environment to the minimal level. When
mitigation is required, no work in waters of the United States may occur until the district
engineer has approved a specific mitigation plan or has determined that prior approval of a final
mitigation plan is not practicable or not necessary to ensure timely completion of the required
compensatory mitigation.

DEFINITIONS
Best mana eg ment practices (BMPs�: Policies, practices, procedures, or structures
implemented to mitigate the adverse environmental effects on surface water quality resulting
from development. BMPs are categorized as structural or non-structural.
Com,pensatory miti ag tion: 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.
Currently serviceable: Useable as is or with some maintenance, but not so degraded as to
essentially require reconstruction.
Direct effects: Effects that are caused by the activity and occur at the same time and
place.
Dischar�e: The term "discharge" means any discharge of dredged or fill material.
Enhancement: The manipulation of the physical, chemical, or biological characteristics of
an aquatic resource to heighten, intensify, or improve a specific aquatic resource function(s).
Enhancement results in the gain of selected aquatic resource function(s), but may also lead to a
decline in other aquatic resource function(s). Enhancement does not result in a gain in aquatic
resource area.
Ephemeral stream: An ephemeral stream has flowing water only during, and for a short
duration after, precipitation events in a typical year. Ephemeral stream beds are located above the
water table year-round. Groundwater is not a source of water for the stream. Runoff from rainfall
is the primary source of water for stream flow.
Establishment (creation�: The manipulation of the physical, chemical, or biological
characteristics present to develop an aquatic resource that did not previously exist at an upland
site. Establishment results in a gain in aquatic resource area.
Hi�h Tide Line: The line of intersection of the land with the water's surface at the
maximum height reached by a rising tide. The high tide line may be determined, in the absence
14

of actual data, by a line of oil or scum along shore objects, a more or less continuous deposit of
fine shell or debris on the foreshore or berm, other physical markings or characteristics,
vegetation lines, tidal gages, or other suitable means that delineate the general height reached by
a rising tide. The line encompasses spring high tides and other high tides that occur with periodic
frequency but does not include storm surges in which there is a departure from the normal or
predicted reach of the tide due to the piling up of water against a coast by strong winds such as
those accompanying a hurricane ar other intense storm.
Historic Property: Any prehistoric or historic district, site (including archaeological site),
building, structure, or other object included in, or eligible for inclusion in, the National Register
of Historic Places maintained by the Secretary of the Interior. This term includes artifacts,
records, and remains that are related to and located within such properties. The term includes
properties of traditional religious and cultural importance to an Indian tribe or Native Hawaiian
organization and that meet the National Register criteria (36 CFR part 60).
Independent utility: A test to determine what constitutes a single and complete non-linear
project in the Corps regulatory program. A project is considered to have independent utility if it
would be constructed absent the construction of other projects in the project area. Portions of a
multi-phase project that depend upon other phases of the project do not have independent utility.
Phases of a project that would be constructed even if the other phases were not built can be
considered as separate single and complete projects with independent utility.
Indirect effects: Effects that are caused by the activity and are later in time or farther
removed in distance, but are still reasonably foreseeable.
Intermittent stream: An intermittent stream has flowing water during certain times of the
year, when groundwater provides water for stream flow. During dry periods, intermittent streams
may not have flowing water. Runoff from rainfall is a supplemental source of water for stream
flow.
Loss of waters of the United States: Waters of the United States that are permanently
adversely affected by filling, flooding, excavation, or drainage because of the regulated activity.
Permanent adverse effects include permanent discharges of dredged or fill material that change
an aquatic area to dry land, increase the bottom elevation of a waterbody, or change the use of a
waterbody. The acreage of loss of waters of the United States is a threshold measurement of the
impact to jurisdictional waters for determining whether a project may qualify for an NWP; it is
not a net threshold that is calculated after considering compensatory mitigation that may be used
to offset losses of aquatic functions and services. The loss of stream bed includes the linear feet
of stream bed that is filled or excavated. Waters of the United States temporarily filled, flooded,
excavated, or drained, but restored to pre-construction contours and elevations after construction,
are not included in the measurement of loss of waters of the United States. Impacts resulting
from activities eligible for exemptions under Section 404(� of the Clean Water Act are not
considered when calculating the loss of waters of the United States.
Non-tidal wetland: A non-tidal wetland is a wetland that is not subject to the ebb and
flow of tidal waters. The definition of a wetland can be found at 33 CFR 328.3(b). Non-tidal
wetlands contiguous to tidal waters are located landward of the high tide line (i.e., spring high
tide line).
O�en water: For purposes of the NWPs, an open water is any area that in a year with
normal patterns of precipitation has water flowing or standing above ground to the extent that an
ordinary high water mark can be determined. Aquatic vegetation within the area of standing or
15

flowing water is either non-emergent, sparse, or absent. Vegetated shallows are considered to be
open waters. Examples of "open waters" include rivers, streams, lakes, and ponds.
Ordinary Hi�h Water Mark: An ordinary high water mark is a line on the shore
established by the fluctuations of water and indicated by physical characteristics, or by other
appropriate means that consider the characteristics of the surrounding areas (see 33 CFR
328.3 (e)).
Perennial stream: A perennial stream has flowing water year-round during a typical year.
The water table is located above the stream bed for most of the year. Groundwater is the primary
source of water for stream flow. Runoff from rainfall is a supplemental source of water for
stream flow.
Practicable: Available and capable of being done after taking into consideration cost,
existing technology, and logistics in light of overall project purposes.
Pre-construction notification: A request submitted by the project proponent to the Corps
for confirmation that a particular activity is authorized by nationwide permit. The request may be
a permit application, letter, or similar document that includes information about the proposed
work and its anticipated environmental effects. Pre-construction notification may be required by
the terms and conditions of a nationwide permit, or by regional conditions. A pre-construction
notification may be voluntarily submitted in cases where pre-construction notification is not
required and the project proponent wants confirmation that the activity is authorized by
nationwide permit.
Preservation: 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: 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.
Rehabilitation: 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.
Restoration: The manipulation of the physical, chemical, or biological characteristics of a
site with the goal of returning natural/historic functions to a former or degraded aquatic resource.
For the purpose of tracking net gains in aquatic resource area, restoration is divided into two
categories: re-establishment and rehabilitation.
Riffle and pool complex: Riffle and pool complexes are special aquatic sites under the
404(b)(1) Guidelines. Riffle and pool complexes sometimes characterize steep gradient sections
of streams. Such stream sections are recognizable by their hydraulic characteristics. The rapid
movement of water over a course substrate in riffles results in a rough flow, a turbulent surface,
and high dissolved oxygen levels in the water. Pools are deeper areas associated with riffles. A
slower stream velocity, a streaming flow, a smooth surface, and a finer substrate characterize
pools.
Riparian areas: Riparian areas are lands adjacent to streams, lakes, and estuarine-marine
shorelines. Riparian areas are transitional between terrestrial and aquatic ecosystems, through
16

which surface and subsurface hydrology connects riverine, lacustrine, estuarine, and marine
waters with their adjacent wetlands, non-wetland waters, or uplands. Riparian areas provide a
variety of ecological functions and services and help improve or maintain local water quality.
(See general condition 23.)
Shellfish seedin�: The placement of shellfish seed and/or suitable substrate to increase
shellfish production. Shellfish seed consists of immature individual shellfish or individual
shellfish attached to shells ar shell fragments (i.e., spat on shell). Suitable substrate may consist
of shellfish shells, shell fragments, or other appropriate materials placed into waters for shellfish
habitat.
Sin�le and complete linear project: A linear project is a project constructed for the
purpose of getting people, goods, or services from a point of origin to a terminal point, which
often involves multiple crossings of one or more waterbodies at separate and distant locations.
The term "single and complete project" is deiined as that portion of the total linear project
proposed or accomplished by one owner/developer or partnership or other association of
owners/developers that includes all crossings of a single water of the United States (i.e., a single
waterbody) at a specific location. For linear projects crossing a single or multiple waterbodies
several times at separate and distant locations, each crossing is considered a single and complete
project for purposes of NWP authorization. However, individual channels in a braided stream or
river, or individual arms of a large, irregularly shaped wetland or lake, etc., are not separate
waterbodies, and crossings of such features cannot be considered separately.
Single and complete non-linear project: For non-linear projects, the term "single and
complete project" is defined at 33 CFR 330.2(i) as the total project proposed or accomplished by
one owner/developer or partnership or other association of owners/developers. A single and
complete non-linear project must have independent utility (see definition of "independent
utility"). Single and complete non-linear projects may not be "piecemealed" to avoid the limits
in an NWP authorization.
Stormwater mana eg ment: Stormwater management is the mechanism for controlling
stormwater runoff for the purposes of reducing downstream erosion, water quality degradation,
and flooding and mitigating the adverse effects of changes in land use on the aquatic
environment.
Stormwater mana�ement facilities: Stormwater management facilities are those facilities,
including but not limited to, stormwater retention and detention ponds and best management
practices, which retain water for a period of time to control runoff and/or improve the quality
(i.e., by reducing the concentration of nutrients, sediments, hazardous substances and other
pollutants) of stormwater runoff.
Stream bed: The substrate of the stream channel between the ordinary high water marks.
The substrate may be bedrock or inorganic particles that range in size from clay to boulders.
Wetlands contiguous to the stream bed, but outside of the ordinary high water marks, are not
considered part of the stream bed.
Stream channelization: The manipulation of a stream's course, condition, capacity, or
location that causes more than minimal interruption of normal stream processes. A channelized
stream remains a water of the United States.
Structure: An object that is arranged in a definite pattern of organization. Examples of
structures include, without limitation, any pier, boat dock, boat ramp, wharf, dolphin, weir,
boom, breakwater, bulkhead, revetment, riprap, jetty, artificial island, artificial reef, permanent
17

mooring structure, power transmission line, permanently moored floating vessel, piling, aid to
navigation, or any other manmade obstacle or obstruction.
Tidal wetland: A tidal wetland is a wetland (i.e., water of the United States) that is
inundated by tidal waters. The definitions of a wetland and tidal waters can be found at 33 CFR
328.3(b) and 33 CFR 328.3(�, respectively. Tidal waters rise and fall in a predictable and
measurable rhythm or cycle due to the gravitational pulls of the moon and sun. Tidal waters end
where the rise and fall of the water surface can no longer be practically measured in a predictable
rhythm due to masking by other waters, wind, or other effects. Tidal wetlands are located
channelward of the high tide line, which is defined at 33 CFR 328.3(d).
Ve�etated shallows: Vegetated shallows are special aquatic sites under the 404(b)(1)
Guidelines. They are areas that are permanently inundated and under normal circumstances have
rooted aquatic vegetation, such as seagrasses in marine and estuarine systems and a variety of
vascular rooted plants in freshwater systems.
Waterbodv: For purposes of the NWPs, a waterbody is a jurisdictional water of the
United States. If a jurisdictional wetland is adjacent — meaning bordering, contiguous, or
neighboring — to a waterbody determined to be a water of the United States under 33 CFR
328.3(a)(1)-(6), that waterbody and its adjacent wetlands are considered together as a single
aquatic unit (see 33 CFR 328.4(c)(2)). Examples of "waterbodies" include streams, rivers, lakes,
ponds, and wetlands.

3.0 List of Corps Regional Conditions for All Nationwide Permits
The following conditions apply to all Nationwide Permits in the Wilmington District:
3.1 Limitation of Loss of Perennial Stream Bed
NWPs may not be used for activities that may result in the loss or degradation of greater than
300 total linear feet of perennial, intermittent or ephemeral stream, unless the District
Commander has waived the 3001inear foot limit for ephemeral and intermittent streams on a
case-by-case basis and he determines that the proposed activity will result in minimal individual
and cumulative adverse impacts to the aquatic environment. Loss of stream includes the linear
feet of stream bed that is filled, excavated, or flooded by the proposed activity. Waivers for the
loss of ephemeral and intermittent streams must be in writing and documented by
appropriate/accepted stream quality assessments*. This waiver only applies to the 3001inear feet
threshold for NWPs.
*NOTE: Applicants should utilize the most current methodology prescribed by Wilmington
District to assess stream function and quality. Information can be found at:
http://www.saw.usace.army.mil/wetlands/permits/nwp/nwp2012 (see "Quick Links")
22

3.2 Mitigation for Loss of Stream Bed
For any NWP that results in a loss of more than 1501inear feet of perennial and/or
ephemeral/intermittent stream, the applicant shall provide a mitigation proposal to compensate
for more than minimal individual and cumulative adverse impacts to the aquatic environment.
For stream losses less than 150 linear feet, that require a PCN, the District Commander may
determine, on a case-by-case basis that compensatory mitigation is required to ensure that the
activity results in minimal adverse effect on the aquatic environment.
3.3 Pre-construction Notification for Loss of Streambed Exceeding 150 Feet.
Prior to use of any NWP for any activity which impacts more than 150 total linear feet of
perennial stream or ephemeral/ intermittent stream, the applicant must comply with Nationwide
Permit General Condition 31 (PCN). This applies to NWPs that do not have specific notification
requirements. If a NWP has specific notification requirements, the requirements of the NWP
should be followed.
3.4 Restriction on Use of Live Concrete
For all NWPs which allow the use of concrete as a building material, live or fresh concrete,
including bags of uncured concrete, may not come into contact with the water in or entering into
waters of the US. Water inside coffer dams or casings that has been in contact with wet concrete
shall only be returned to waters of the US when it is no longer poses a threat to aquatic
orgamsms.
3.5 Requirements for Using Riprap for Bank Stabilization
For all NWPs that allow for the use of riprap material for bank stabilization, the following
measures shall be applied:
3.5.1. Filter cloth must be placed underneath the riprap as an additional requirement of its use in
North Carolina waters.
3.5.2. The placement of riprap shall be limited to the areas depicted on submitted work plan
drawings.
3.5.3. The riprap material shall be clean and free from loose dirt or any pollutant except in trace
quantities that would not have an adverse environmental effect.
3.5.4. It shall be of a size sufficient to prevent its movement from the authorized alignment by
natural forces under normal conditions.
3.5.5. The riprap material shall consist of clean rock or masonry material such as, but not limited
to, granite, marl, or broken concrete.

3.5.6. A waiver from the specifications in this Regional Condition may be requested in writing.
The waiver will only be issued if it can be demonstrated that the impacts of complying with this
Regional condition would result in greater adverse impacts to the aquatic environment.
3.6 Safe Passage Requirements for Culvert Placement
For all NWPs that involve the construction/installation of culverts, measures will be included in
the construction/installation that will promote the safe passage of fish and other aquatic
organisms. The dimension, pattern, and pro�le of the stream above and below a pipe or culvert
should not be modified by widening the stream channel or by reducing the depth of the stream in
connection with the construction activity. The width, height, and gradient of a proposed culvert
should be such as to pass the average historicallow flow and spring flow without adversely
altering flow velocity. Spring flow should be determined from gage data, if available. In the
absence of such data, bankfull flow can be used as a comparable level.
In the twenty (20) counties of North Carolina designated as coastal counties by the Coastal Area
Management Act (CAMA): All pipes/culverts must be sufficiently sized to allow for the burial of
the bottom of the pipe/culvert at least one foot below normal bed elevation when they are placed
within the Public Trust Area of Environmental Concern (AEC) and/or the Estuarine Waters AEC
as designated by CAMA, and/or all streams appearing as blue lines on United States Geological
Survey (USGS) 7.5-minute quadrangle maps.

In all other counties: Culverts greater than 48 inches in diameter will be buried at least one foot
below the bed of the stream. Culverts 48 inches in diameter or less shall be buried or placed on
the stream bed as practicable and appropriate to maintain aquatic passage, and every effort shall
be made to maintain the existing channel slope. The bottom of the culvert must be placed at a
24

depth below the natural stream bottom to provide for passage during drought or low flow
conditions.
Culverts are to be designed and constructed in a manner that minimizes destabilization and head
cutting. Destabilizing the channel and head cutting upstream should be considered and
appropriate actions incorporated in the design and placement of the culvert.
A waiver from the depth specifications in this condition may be requested in writing. The waiver
will be issued if it can be demonstrated that the proposal would result in the least impacts to the
aquatic environment.
All counties: Culverts placed within riparian and/or riverine wetlands must be installed in a
manner that does not restrict the flow and circulation patterns of waters of the United States.
Culverts placed across wetland fills purely for the purposes of equalizing surface water do not
have to be buried.
3.7 Notification to NCDENR Shellfish Sanitation Section
Applicants shall notify the NCDENR Shellfish Sanitation Section prior to dredging in or
removing sediment from an area closed to shell fishing where the effluent may be released to an
area open for shell fishing or swimming in order to avoid contamination from the disposal area
and cause a temporary shellfish closure to be made. Such notification shall also be provided to
the appropriate Corps of Engineers Regulatory Field Office. Any disposal of sand to the ocean
beach should occur between November 1 and Apri130 when recreational usage is low. Only
clean sand should be used and no dredged sand from closed shell fishing areas may be used. If
beach disposal were to occur at times other than stated above or if sand from a closed shell
fishing area is to be used, a swimming advisory shall be posted, and a press release shall be
issued by the permittee.
3.8 Preservation of Submerged Aquatic Vegetation
Adverse impacts to Submerged Aquatic Vegetation (SAV) are not authorized by any NWP
within any of the twenty coastal counties defined by North Carolina's Coastal Area Management
Act of 1974 (CAMA).
3.9 Sedimentation and Erosion Control Structures and Measures
3.9.1. All PCNs will identify and describe sedimentation and erosion control structures and
measures proposed for placement in waters of the US. The structures and measures should be
depicted on maps, surveys or drawings showing location and impacts to jurisdictional wetlands
and streams.

4.0 Additional Regional Conditions for Specific Nationwide Permits
4.1 NWP # 13 — Bank Stabilization
41.1. Unanchored trees, treetops, or debris may not be used as stream bank stabilization
material.
41.2. Properly anchored and cabled structural stabilization techniques, such as timber crib
structures, revetments, and root wads, are acceptable materials to stabilize stream banks.
4.1.3. If riprap stabilization is needed, it should be placed only on the stream banks, or, if it is
necessary to be placed in the stream bed, the iinished top elevation of the riprap should not
exceed that of the original stream bed.
