August 18, 2021
Reference: NWS-2021-209
Van Zandt, Greg
We have reviewed your application to replace piling and floats in Flounder Bay (Skyline
Marina) at Anacortes, Skagit County, Washington. Based on the information you provided to us,
Nationwide Permit (NWP) 3, Maintenance (Federal Register January 6, 2017, Vol. 82, No. 4),
authorizes your proposal as depicted on the enclosed drawings dated August 7, 2021. In order
for this authorization to be valid, you must ensure the work is performed in accordance with the
enclosed NWP 3, Terms and Conditions and the following special condition:
a. No residue from construction activity shall be allowed to remain in waters of the
U. S. The permittee must install and maintain debris collection measures until all project
operations are complete.
b. In order to meet the requirements of the Endangered Species Act (ESA) and Magnuson -
Stevens Fishery Conservation and Management Act (MSA) Phase I programmatic consultation
(National Marine Fisheries Service (NMFS) Reference Number 2005-07506; U.S. Fish and
Wildlife Service (USFWS) Reference Number 01EWFW00-2015-I-0104), you must implement
and abide by the List of Requirements for Piling Replacement dated May 3, 2017, available on
the U.S. Army Corps of Engineers (Corps) website (Permit Guidebook, Endangered Species,
Programmatic Consultations, Various Activities throughout Washington State typically
authorized by Nationwide Permit (Phase I)). In addition, you must comply with the relevant
conservation measures in the General Implementation Conditions also available on the Corps
website. Failure to comply with the commitments made in this document constitutes non-
compliance with the ESA and your Corps permit. If you cannot comply with the terms and
conditions of this programmatic consultation, you must, prior to commencing construction,
contact the Corps, Seattle District, Regulatory Branch for an individual consultation in
accordance with the requirements of the ESA and/or the Magnuson -Stevens Fishery
Conservation and Management Act. The USFWS/NMFS is the appropriate authority to
determine compliance with the ESA.

c. In order to meet the requirements of the Endangered Species Act and protect Puget
Sound Chinook, Puget Sound steelhead, and Coastal -Puget Sound bull trout, the permittee may
conduct the authorized in -water activities from July 16th through February 151h in any year this
permit is valid. No in -water work authorized by this permit shall occur from February 16th
through July 15th
d. Incidents where any individuals of fish species, marine mammals and/or sea turtles listed
by National Oceanic and Atmospheric Administration Fisheries (NOAA Fisheries) under the
Endangered Species Act appear to be injured or killed as a result of discharges of dredged or fill
material into waters of the U.S. or structures or work in navigable waters of the U.S. authorized
by this Nationwide Permit verification shall be reported to NOAA Fisheries, Office of Protected
Resources at (301) 713-1401 and the Regulatory Office of the Seattle District of the U.S. Army
Corps of Engineers at (206) 764-3495. The finder should leave the animal alone, make note of
any circumstances likely causing the death or injury, note the location and number of individuals
involved and, if possible, take photographs. Adult animals should not be disturbed unless
circumstances arise where they are obviously injured or killed by discharge exposure or some
unnatural cause. The finder may be asked to carry out instructions provided by NOAA Fisheries
to collect specimens or take other measures to ensure that evidence intrinsic to the specimen is
preserved.
We have reviewed your project pursuant to the requirements of the Endangered Species Act,
the Magnuson -Stevens Fishery Conservation and Management Act and the National Historic
Preservation Act. We have determined this project complies with the requirements of these laws
provided you comply with all of the permit general and special conditions.
The authorized work complies with the Washington State Department of Ecology's
(Ecology) Water Quality Certification and the Coastal Zone Management Act requirements for
this NWP. No further coordination with Ecology is required.
You have not requested a jurisdictional determination for this proposed project. If you
believe the Corps does not have jurisdiction over all or portions of your project you may request
a preliminary or approved jurisdictional determination (JD). If one is requested, please be aware
that we may require the submittal of additional information to complete the JD and work
authorized in this letter may not occur until the JD has been completed.
Our verification of this NWP authorization is valid until March 18, 2022, unless the NWP is
modified, reissued, or revoked prior to that date. If the authorized work has not been completed
by that date and you have commenced or are under contract to commence this activity before
March 18, 2022, you will have until March 18, 2023, to complete the activity under the enclosed
terms and conditions of this NWP. Failure to comply with all terms and conditions of this NWP
verification invalidates this authorization and could result in a violation of Section 404 of the
-3-
Clean Water Act and/or Section 10 of the Rivers and Harbors Act. You must also obtain all
local, State, and other Federal permits that apply to this project.
You are cautioned that any change in project location or plans will require that you submit a
copy of the revised plans to this office and obtain our approval before you begin work. Deviating
from the approved plans could result in the assessment of criminal or civil penalties.
Upon completing the authorized work, you must fill out and return the enclosed Certificate
of Compliance with Department of the Army Permit. Thank you for your cooperation during the

US Army Corps
of Engineers Seattle District Terms and Conditions
Effective Date: March 19, 2017
A. Description of Authorized Activities
B. U.S. Army Corps of Engineers (Corps) National General Conditions for all NWPs
C. Corps Seattle District Regional General Conditions
D. Corps Regional Specific Conditions for this NWP
E. Washington Department of Ecology (Ecology) Section 401 Water Quality Certification (401
Certification): General Conditions
F. Ecology 401 Certification: Specific Conditions for this NWP
G. Coastal Zone Management Consistency Response for this NWP
In addition to any special condition that may be required on a case -by -case basis by the District Engineer,
the following terms and conditions must be met, as applicable, for a Nationwide Permit (NWP)
authorization to be valid in Washington State.
A. DESCRIPTION OF AUTHORIZED ACTIVITIES
3. Maintenance. (a) The repair, rehabilitation, or replacement of any previously authorized, currently
serviceable structure or fill, or of any currently serviceable structure or fill authorized by 33 CFR 330.3,
provided that the structure or fill is not to be put to uses differing from those uses specified or
contemplated for it in the original permit or the most recently authorized modification. Minor deviations
in the structure's configuration or filled area, including those due to changes in materials, construction
techniques, requirements of other regulatory agencies, or current construction codes or safety standards
that are necessary to make the repair, rehabilitation, or replacement are authorized. This NWP also
authorizes the removal of previously authorized structures or fills. Any stream channel modification is
limited to the minimum necessary for the repair, rehabilitation, or replacement of the structure or fill; such
modifications, including the removal of material from the stream channel, must be immediately adjacent
to the project. This NWP also authorizes the removal of accumulated sediment and debris within, and in
the immediate vicinity of, the structure or fill. This NWP also authorizes the repair, rehabilitation, or
replacement of those structures or fills destroyed or damaged by storms, floods, fire or other discrete
events, provided the repair, rehabilitation, or replacement is commenced, or is under contract to
commence, within two years of the date of their destruction or damage. In cases of catastrophic events,
such as hurricanes or tornadoes, this two-year limit may be waived by the district engineer, provided the
permittee can demonstrate funding, contract, or other similar delays. (b) This NWP also authorizes the
removal of accumulated sediments and debris outside the immediate vicinity of existing structures (e.g.,
bridges, culverted road crossings, water intake structures, etc.). The removal of sediment is limited to the
minimum necessary to restore the waterway in the vicinity of the structure to the approximate dimensions
that existed when the structure was built, but cannot extend farther than 200 feet in any direction from the
structure. This 200 foot limit does not apply to maintenance dredging to remove accumulated sediments
blocking or restricting outfall and intake structures or to maintenance dredging to remove accumulated
sediments from canals associated with outfall and intake structures. All dredged or excavated materials
must be deposited and retained in an area that has no waters of the United States unless otherwise
specifically approved by the district engineer under separate authorization. (c) This NWP also authorizes
temporary structures, fills, and work, including the use of temporary mats, necessary to conduct the
maintenance 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. After conducting the maintenance activity, 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. (d) This NWP does not authorize maintenance dredging for the
primary purpose of navigation. This NWP does not authorize beach restoration. This NWP does not
authorize new stream channelization or stream relocation projects. Notification: For activities authorized
by paragraph (b) of this NWP, the permittee must submit a pre -construction notification to the district
engineer prior to commencing the activity (see general condition 32). The pre -construction notification
must include information regarding the original design capacities and configurations of the outfalls,
intakes, small impoundments, and canals. (Authorities: Section 10 of the Rivers and Harbors Act of 1899
and section 404 of the Clean Water Act (Sections 10 and 404)) Note: This NWP authorizes the repair,
rehabilitation, or replacement of any previously authorized structure or fill that does not qualify for the
Clean Water Act section 404(f) exemption for maintenance.
B. CORPS NATIONAL GENERAL CONDITIONS FOR ALL NWPs
To qualify for NWP authorization, the prospective permittee must comply with the following general
conditions, as applicable, in addition to any regional or case -specific conditions imposed by the division
engineer or district engineer. Every person who may wish to obtain permit authorization under one or
more NWPs, or who is currently relying on an existing or prior permit authorization under one or more
NWPs, has been and is on notice that all of the provisions of 33 CFR 330.1 through 330.6 apply to every
NWP authorization. Note especially 33 CFR 330.5 relating to the modification, suspension, or revocation
of any NWP authorization.
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 or his authorized representative, said structure or 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. If a bottomless culvert cannot be
used, then the crossing should be designed and constructed to minimize adverse effects to aquatic life
movements.
3. Spawning Ate. 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. Mi rg atory Bird Breeding Ate. 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 NWP 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 Supply 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.
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. Management 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, storm water management activities, and temporary and permanent road crossings, 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, or during low tides.
13. Removal of Temporary. 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. (a) No NWP 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. (b) If a proposed NWP
activity will 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, the permittee must submit a pre -construction notification (see general condition 32).
The district engineer will coordinate the PCN with the Federal agency with direct management
responsibility for that river. The permittee shall not begin the NWP activity until notified by the district
engineer that the Federal agency with direct management responsibility for that river has determined in
writing that the proposed NWP activity will not adversely affect the Wild and Scenic River designation or
study status. (c) 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). Information on these rivers is also available at: http://www.rivers.gov/.
17. Tribal Rights. No NWP activity may cause more than minimal adverse effects on tribal rights
(including treaty rights), protected tribal resources, or tribal lands.
18. Endangeredpecies. (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
authorized under any NWP which "may affect" a listed species or critical habitat, unless ESA section 7
consultation addressing the effects of the proposed activity has been completed. Direct effects are the
immediate effects on listed species and critical habitat caused by the NWP activity. Indirect effects are
those effects on listed species and critical habitat that are caused by the NWP activity and are later in
time, but still are reasonably certain to occur. (b) Federal agencies should follow their own procedures for
complying with the requirements of the ESA. If pre -construction notification is required for the proposed
activity, the Federal permittee must provide the district engineer with the appropriate documentation to
demonstrate compliance with those requirements. The district engineer will verify that the appropriate
documentation has been submitted. If the appropriate documentation has not been submitted, additional
ESA section 7 consultation may be necessary for the activity and the respective federal agency would be
responsible for fulfilling its obligation under section 7 of the ESA. (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 activity, or if the activity 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 authorized. 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 activity or that utilize the designated critical habitat that might be affected by the proposed
activity. 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 activity, and has so notified the Corps, the applicant shall not begin work until the Corps
has provided notification that the proposed activity will have "no effect" on listed species or critical
habitat, or until ESA 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 permit conditions to the NWPs. (e) Authorization of an activity by an 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 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
4
"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.
(f) If the non-federal permittee has a valid ESA section 10(a)(1)(B) incidental take permit with an
approved Habitat Conservation Plan for a project or a group of projects that includes the proposed NWP
activity, the non-federal applicant should provide a copy of that ESA section 10(a)(1)(B) permit with the
PCN required by paragraph (c) of this general condition. The district engineer will coordinate with the
agency that issued the ESA section 10(a)(1)(B) permit to determine whether the proposed NWP activity
and the associated incidental take were considered in the internal ESA section 7 consultation conducted
for the ESA section 10(a)(1)(B) permit. If that coordination results in concurrence from the agency that
the proposed NWP activity and the associated incidental take were considered in the internal ESA section
7 consultation for the ESA section I0(a)(1)(B) permit, the district engineer does not need to conduct a
separate ESA section 7 consultation for the proposed NWP activity. The district engineer will notify the
non-federal applicant within 45 days of receipt of a complete pre -construction notification whether the
ESA section 10(a)(1)(B) permit covers the proposed NWP activity or whether additional ESA section 7
consultation is required. (g) Information on the location of threatened and endangered species and their
critical habitat can be obtained directly from the offices of the FWS and NMFS or their world wide web
pages at http://www.fws.gov/ or http://www.fws.gov/ipac and http://www.nmfs.noaa.gov/pr/species/esa/
respectively.
19. Migratory Birds and Bald and Golden Eagles. The permittee is responsible for ensuring their action
complies with the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act. The
permittee is responsible for contacting appropriate local office of the U.S. Fish and Wildlife Service to
determine applicable measures to reduce impacts to migratory birds or eagles, including whether
"incidental take" permits are necessary and available under the Migratory Bird Treaty Act or Bald and
Golden Eagle Protection Act for a particular activity.
20. Historic Properties. (a) In cases where the district engineer determines that the activity may have the
potential to cause effects to properties listed, or eligible for 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. If pre -
construction notification is required for the proposed NWP activity, the Federal permittee must provide
the district engineer with the appropriate documentation to demonstrate compliance with those
requirements. The district engineer will verify that the appropriate documentation has been submitted. If
the appropriate documentation is not submitted, then additional consultation under section 106 may be
necessary. The respective federal agency is responsible for fulfilling its obligation to comply with section
106. (c) Non-federal permittees must submit a pre -construction notification to the district engineer if the
NWP activity might 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 might have the potential to be affected by the proposed NWP activity 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 properties can be sought from the State Historic Preservation Officer, Tribal Historic Preservation
Officer, or designated tribal representative, 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 in the PCN
and these identification efforts, the district engineer shall determine whether the proposed NWP activity
has the potential to cause effects on the historic properties. Section 106 consultation is not required when
the district engineer determines that the activity does not have the potential to cause effects on historic
properties (see 36 CFR 800.3(a)). Section 106 consultation is required when the district engineer
determines that the activity has the potential to cause effects on historic properties. The district engineer
will conduct consultation with consulting parties identified under 36 CFR 800.2(c) when he or she makes
any of the following effect determinations for the purposes of section 106 of the NHPA: no historic
properties affected, no adverse effect, or adverse effect. Where the non -Federal applicant has identified
historic properties on which the activity might 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 to historic properties or that NHPA section 106
consultation has been completed. (d) For non-federal permittees, 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. If NHPA section 106 consultation is required, the district
engineer will notify the non -Federal applicant that he or she cannot begin the activity 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 (54 U.S.C. 306113) 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, 38, and 54, notification is required in accordance with general condition 32, 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.
6
23. Miti ag tion. The district engineer will consider the following factors when determining appropriate and
practicable mitigation necessary to ensure that the individual and cumulative adverse environmental
effects are no more than 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 individual and cumulative adverse environmental effects are no more than 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 environmental effects of the proposed activity are no more than minimal, and provides an
activity -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 only minimal adverse environmental effects.
(d) For losses of streams or other open waters that require pre -construction notification, the district
engineer may require compensatory mitigation to ensure that the activity results in no more than minimal
adverse environmental effects. Compensatory mitigation for losses of streams should be provided, if
practicable, through stream rehabilitation, enhancement, or preservation, since streams are difficult -to -
replace resources (see 33 CFR 332.3(e)(3)). (e) Compensatory mitigation plans for NWP activities in or
near streams or other open waters will normally include a requirement for the restoration or enhancement,
maintenance, and legal protection (e.g., conservation easements) of riparian areas next to open waters. In
some cases, the restoration or maintenance/protection of riparian areas may be the only compensatory
mitigation required. Restored 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 restore or maintain/protect a riparian area on both sides of a stream, or if the waterbody is a
lake or coastal waters, then restoring or maintaining/protecting 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 minimization or compensatory
mitigation, the district engineer may waive or reduce the requirement to provide wetland compensatory
mitigation for wetland losses. (f) 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 no more than
minimal adverse environmental effects. For the NWPs, the preferred mechanism for providing
compensatory mitigation is mitigation bank credits or in -lieu fee program credits (see 33 CFR
332.3(b)(2) and (3)). However, if an appropriate number and type of mitigation bank or in -lieu credits
are not available at the time the PCN is submitted to the district engineer, the district engineer may
approve the use of permittee-responsible mitigation. (2) The amount of compensatory mitigation
required by the district engineer must be sufficient to ensure that the authorized activity results in no
more than minimal individual and cumulative adverse environmental effects (see 33 CFR
330.1(e)(3)). (See also 33 CFR 332.3(f)). (3) Since the likelihood of success is greater and the
impacts to potentially valuable uplands are reduced, aquatic resource restoration should be the first
compensatory mitigation option considered for permittee-responsible mitigation. (4) 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) through (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)). (5) 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. (6)
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 (see 33 CFR 332.4(c)(1)(ii)).
(g) 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
NWP activity resulting in the loss of greater than 1/2-acre of waters of 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 an NWP activity already
meeting the established acreage limits also satisfies the no more than minimal impact requirement for the
NWPs. (h) Permittees may propose the use of mitigation banks, in -lieu fee programs, or permittee-
responsible mitigation. When developing a compensatory mitigation proposal, the permittee must
consider appropriate and practicable options consistent with the framework at 33 CFR 332.3(b). For
activities resulting in the loss of marine or estuarine resources, permittee-responsible 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. (i) Where certain functions and services of waters of the United
States are permanently adversely affected by a regulated activity, such as discharges of dredged or fill
material into waters of the United States that will convert 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 environmental effects of the activity to the no more than 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 Quality. Where States and authorized Tribes, or EPA where applicable, have not previously
certified compliance of an NWP with CWA section 401, individual 401 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 Management. 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. Regional 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
project 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 Verifications. 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
implementation of 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: (a) A statement that the authorized
activity 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 activity and mitigation. The completed certification document must be submitted to the district
engineer within 30 days of completion of the authorized activity or the implementation of any required
compensatory mitigation, whichever occurs later.
31. Activities Affecting Structures or Works Built by the United States. If an NWP activity also requires
permission from the Corps pursuant to 33 U.S.C. 408 because it will alter or temporarily or permanently
occupy or use a U.S. Army Corps of Engineers (USACE) federally authorized Civil Works project (a
"USACE project"), the prospective permittee must submit a pre -construction notification. See paragraph
(b)(10) of general condition 32. An activity that requires section 408 permission is not authorized by
NWP until the appropriate Corps office issues the section 408 permission to alter, occupy, or use the
USACE project, and the district engineer issues a written NWP verification.
32. Pre -Construction Notification. (a) Timing. 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 are in the vicinity of the activity, or to notify the Corps pursuant to
general condition 20 that the activity might 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(f)) and/or section 106 of the
National Historic Preservation Act (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 activity;
(3) Identify the specific NWP or NWP(s) the prospective permittee wants to use to authorize
the proposed activity;
(4) A description of the proposed activity; the activity's purpose; direct and indirect adverse
environmental effects the activity would cause, including the anticipated amount of loss of wetlands,
other special aquatic sites, and other waters expected to result from the NWP activity, in acres, linear
feet, or other appropriate unit of measure; a description of any proposed mitigation measures intended
to reduce the adverse environmental effects caused by the proposed activity; and any other NWP(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, including other separate and distant crossings for linear
projects that require Department of the Army authorization but do not require pre -construction
notification. The description of the proposed activity and any proposed mitigation measures should be
sufficiently detailed to allow the district engineer to determine that the adverse environmental effects
of the activity will be no more than minimal and to determine the need for compensatory mitigation
or other mitigation measures. For single and complete linear projects, the PCN must include the
quantity of anticipated losses of wetlands, other special aquatic sites, and other waters for each single
and complete crossing of those wetlands, other special aquatic sites, and other waters. Sketches
should be provided when necessary to show that the activity complies with the terms of the NWP.
(Sketches usually clarify the activity 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);
(5) 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
10
large or contains many wetlands, other special aquatic sites, and other waters. Furthermore, the 45
day period will not start until the delineation has been submitted to or completed by the Corps, as
appropriate;
(6) 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 environmental effects are no more than
minimal and why compensatory mitigation should not be required. As an alternative, the prospective
permittee may submit a conceptual or detailed mitigation plan.
(7) For non -Federal permittees, if any listed species or designated critical habitat might be
affected or is in the vicinity of the activity, or if the activity is located in designated critical habitat,
the PCN must include the name(s) of those endangered or threatened species that might be affected
by the proposed activity or utilize the designated critical habitat that might be affected by the
proposed activity. For NWT activities that require pre -construction notification, Federal permittees
must provide documentation demonstrating compliance with the Endangered Species Act;
(8) For non -Federal permittees, if the NWP activity might have the potential to cause effects
to a historic property listed on, determined to be eligible for listing on, or potentially eligible for
listing on, the National Register of Historic Places, the PCN must state which historic property might
have the potential to be affected by the proposed activity or include a vicinity map indicating the
location of the historic property. For NWP activities that require pre -construction notification, Federal
permittees must provide documentation demonstrating compliance with section 106 of the National
Historic Preservation Act;
(9) For an activity that will 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, the PCN must identify the Wild and Scenic River
or the "study river" (see general condition 16); and
(10) For an activity that requires permission from the Corps pursuant to 33 U.S.C. 408
because it will alter or temporarily or permanently occupy or use a U.S. Army Corps of Engineers
federally authorized civil works project, the pre -construction notification must include a statement
confirming that the project proponent has submitted a written request for section 408 permission from
the Corps office having jurisdiction over that USACE project.
(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 an NWP PCN and
must include all of the applicable information required in paragraphs (b)(1) through (10) of this general
condition. A letter containing the required information may also be used. Applicants may provide
electronic files of PCNs and supporting materials if the district engineer has established tools and
procedures for electronic submittals. (d) Agency 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 activity's adverse environmental
effects so that they are no more than minimal. (2) Agency coordination is required for: (i) 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; (ii) 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 300 linear feet of stream bed; (iii) NWP
13 activities in excess of 500 linear feet, fills greater than one cubic yard per running foot, or involve
discharges of dredged or fill material into special aquatic sites; and (iv) NWP 54 activities in excess of
500 linear feet, or that extend into the waterbody more than 30 feet from the mean low water line in tidal
waters or the ordinary high water mark in the Great Lakes. (3) When agency coordination is required, 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 (FWS,
state natural resource or water quality agency, EPA, 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 notify
the district engineer via telephone, facsimile transmission, or e-mail that they intend to provide
substantive, site -specific comments. The comments must explain why the agency believes the adverse
11
environmental 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 of the proposed activity are no more
than 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.
(4) 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. (5) Applicants are encouraged to provide the Corps with either electronic files or
multiple copies of pre -construction notifications to expedite agency coordination.
District Engineer'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 maybe contrary to the public interest. If a project
proponent requests authorization by a specific NWP, the district engineer should issue the NWP
verification for that activity if it meets the terms and conditions of that NWP, unless he or she determines,
after considering mitigation, that the proposed activity will result in more than minimal individual and
cumulative adverse effects on the aquatic environment and other aspects of the public interest and
exercises discretionary authority to require an individual permit for the proposed activity. For a linear
project, this determination will include an evaluation of the individual crossings of waters of the United
States 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 300 linear foot limit on impacts to streams or of an otherwise applicable limit, as provided for in
NWPs 13, 21, 29, 36, 39, 40, 42, 43, 44, 50, 51, 52, or 54, the district engineer will only grant the waiver
upon a written determination that the NWP activity will result in only minimal individual and cumulative
adverse environmental effects. For those NWPs that have a waivable 300 linear foot limit for losses of
intermittent and ephemeral stream bed and a 1/2-acre limit (i.e., NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51,
and 52), the loss of intermittent and ephemeral stream bed, plus any other losses of jurisdictional waters
and wetlands, cannot exceed 1/2-acre. 2. When making minimal adverse environmental effects
determinations the district engineer will consider the direct and indirect effects caused by the NWP
activity. He or she will also consider the cumulative adverse environmental effects caused by activities
authorized by NWP and whether those cumulative adverse environmental effects are no more than
minimal. The district engineer will also consider site specific factors, such as the environmental setting in
the 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 or condition assessment method is available and practicable to use, that assessment method
may be used by the district engineer to assist in the minimal adverse environmental effects determination.
The district engineer may add case -specific special conditions to the NWP authorization to address site -
specific environmental concerns. 3. 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 NWP activities with smaller impacts, or
12
for impacts to other types of waters (e.g., streams). The district engineer will consider any proposed
compensatory mitigation or other mitigation measures the applicant has included in the proposal in
determining whether the net adverse environmental effects of the proposed activity are no more than
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 environmental effects are no more than 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 the NWP activity results in no more than minimal adverse environmental effects.
If the net adverse environmental effects of the NWP activity (after consideration of the mitigation
proposal) are determined by the district engineer to be no more than minimal, the district engineer will
provide a timely written response to the applicant. The response will state that the NWP activity can
proceed under the terms and conditions of the NWP, including any activity -specific conditions added to
the NWP authorization by the district engineer. 4. If the district engineer determines that the adverse
environmental effects of the proposed activity are more than minimal, then the district engineer will
notify the applicant either: (a) that the activity 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
activity is authorized under the NWP subject to the applicant's submission of a mitigation plan that would
reduce the adverse environmental effects so that they are no more than minimal; or (c) that the activity is
authorized under the NWP with specific modifications or conditions. Where the district engineer
determines that mitigation is required to ensure no more than minimal adverse environmental effects, the
activity will be authorized within the 45-day PCN period (unless additional time is required to comply
with general conditions 18, 20, and/or 31, or to evaluate PCNs for activities authorized by NWPs 21, 49,
and 50), with activity -specific conditions that state the mitigation requirements. The authorization will
include the necessary conceptual or detailed mitigation plan or a requirement that the applicant submit a
mitigation plan that would reduce the adverse environmental effects so that they are no more than
minimal. When compensatory 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.
Further Information: 1. District Engineers have authority to determine if an activity complies with the
terms and conditions of an NWP. 2. NWPs do not obviate the need to obtain other federal, state, or local
permits, approvals, or authorizations required by law. 3. NWPs do not grant any property rights or
exclusive privileges. 4. NWPs do not authorize any injury to the property or rights of others. 5. NWPs do
not authorize interference with any existing or proposed Federal project (see general condition 31).
C. CORPS SEATTLE DISTRICT REGIONAL GENERAL CONDITIONS: The following conditions
apply to all NWPs for the Seattle District in Washington State, unless specified.
1. Proiect Drawings: Drawings must be submitted with pre -construction notification (PCN). Drawings
must provide a clear understanding of the proposed project, and how waters of the U.S. will be affected.
Drawings must be originals and not reduced copies of large-scale plans. Engineering drawings are not
required. Existing and proposed site conditions (manmade and landscape features) must be drawn to
scale.
13
2. Aquatic Resources Requiring Special Protection: Activities resulting in a loss of waters of the
United States in mature forested wetlands, bogs and peatlands, aspen -dominated wetlands, alkali
wetlands, vernal pools, camas prairie wetlands, estuarine wetlands, wetlands in coastal lagoons, and
wetlands in dunal systems along the Washington coast cannot be authorized by a NWP, except by the
following NWPs:
NWP 3 — Maintenance
NWP 20 — Response Operations for Oil and Hazardous Substances
NWP 32 — Completed Enforcement Actions
NWP 38 — Cleanup of Hazardous and Toxic Waste
In order to use one of the above -referenced NWPs in any of the aquatic resources requiring special
protection, prospective permittees must submit a PCN to the Corps of Engineers (see NWP general
condition 32) and obtain written authorization before commencing work.
3. New Bank Stabilization in Tidal Waters of Puget Sound: Activities involving new bank
stabilization in tidal waters in Water Resource Inventory Areas (WRIAs)
8, 9, 10, 11 and 12 (within the areas identified on Figures I through I on Corps website) cannot be
authorized by NWP.
4. Commencement Bay: The following NWPs may not be used to authorize activities located in the
Commencement Bay Study Area (see Figure 2 on Corps website):
NWP 12 — Utility Line Activities (substations)
NWP 13 — Bank Stabilization
NWP 14
— Linear Transportation Projects
NWP 23
— Approved Categorical Exclusions
NWP 29
— Residential Developments
NWP 39
— Commercial and Institutional Developments
NWP 40
— Agricultural Activities
NWP 41
— Reshaping Existing Drainage Ditches
NWP 42
— Recreational Facilities
NWP 43
— Stormwater and Wastewater Management Facilities
5. Bank Stabilization: All projects including new or maintenance bank stabilization activities require
PCN to the Corps of Engineers (see NWP general condition 32). For new bank stabilization projects only,
the following must be submitted to the Corps of Engineers:
a. The cause of the erosion and the distance of any existing structures from the area(s) being
stabilized.
b. The type and length of existing bank stabilization within 300 feet of the proposed project.
c. A description of current conditions and expected post -project conditions in the waterbody.
d. A statement describing how the project incorporates elements avoiding and minimizing adverse
environmental effects to the aquatic environment and nearshore riparian area, including vegetation
impacts in the waterbody.
In addition to a. through d., the results from any relevant geotechnical investigations can be submitted
with the PCN if it describes current or expected conditions in the waterbody.
6. Crossings of Waters of the United States: Any project including installing, replacing, or modifying
crossings of waters of the United States, such as culverts or bridges, requires submittal of a PCN to the
Corps of Engineers (see NWP general condition 32). If a culvert is proposed to cross waters of the U.S.
where salmonid species are present or could be present, the project must apply the stream simulation
design method from the Washington Department of Fish and Wildlife located in the Water Crossing
Design Guidelines (2013), or a design method which provides passage at all life stages at all flows where
the salmonid species would naturally seek passage. If the stream simulation design method is not applied
14
for a culvert where salmonid species are present or could be present, the project proponent must provide a
rationale in the PCN sufficient to establish one of the following:
a. The existence of extraordinary site conditions.
b. How the proposed design will provide equivalent or better fish passage and fisheries habitat
benefits than the stream simulation design method.
If a culvert is proposed to cross waters of the U.S. where salmonid species are present or could be present,
project proponents must provide a monitoring plan with the PCN that specifies how the proposed culvert
will be assessed over a five-year period from the time of construction completion to ensure its
effectiveness in providing passage at all life stages at all flows where the salmonid species would
naturally seek passage. Culverts installed under emergency authorization that do not meet the above
design criteria will be required to meet the above design criteria to receive an after -the -fact nationwide
permit verification.
7. Stream Loss: A PCN is required for all activities that result in the loss of any linear feet of stream
beds. No activity shall result in the loss of any linear feet of perennial stream beds or the loss of greater
than 300 linear feet of intermittent and/or ephemeral stream beds. A stream may be rerouted if it is
designed in a manner that maintains or restores hydrologic, ecologic, and geomorphic stream processes,
provided there is not a reduction in the linear feet of stream bed. Streams include brooks, creeks, rivers,
and historical waters of the U.S. that have been channelized into ditches. This condition does not apply to
ditches constructed in uplands. Stream loss restrictions may be waived by the district engineer on a case -
by -case basis provided the activities result in net increases of aquatic resource functions and services.
8. Mitigation: Pre -construction notification is required for any project that will result in permanent
wetland losses that exceed 1,000 square feet. In addition to the requirements of General Condition 23
(Mitigation), compensatory mitigation at a minimum one-to-one ratio will be required for all permanent
wetland losses that exceed 1,000 square feet. When a PCN is required for wetland losses less than 1,000
square feet, the Corps of Engineers 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 for impacts to marine waters, lakes, and streams will be determined on a case -
by -case basis. If temporary impacts to waters of the U.S. exceed six months, the Corps of Engineers may
require compensatory mitigation for temporal effects.
9. Magnuson -Stevens Fishery Conservation and Management Act — Essential Fish Habitat
Essential Fish Habitat (EFH) is defined as those waters and substrate necessary to fish for spawning,
breeding, feeding, or growth to maturity. If EFH may be adversely affected by a proposed activity, the
prospective permittee must provide a written EFH assessment with an analysis of the effects of the
proposed action on EFH. The assessment must identify the type(s) of essential fish habitat (i.e., Pacific
salmon, groundfish, and/or coastal -pelagic species) that may be affected. If the Corps of Engineers
determines the project will adversely affect EFH, consultation with NOAA Fisheries will be required.
Federal agencies should follow their own procedures for complying with the requirements of the
Magnuson -Stevens Fishery Conservation and Management Act. If PCN is required for the proposed
activity, Federal permittees must provide the district engineer with the appropriate documentation to
demonstrate compliance with those requirements.
10. Forage Fish: For projects in forage fish spawning habitat, in -water work must occur within
designated forage fish work windows, or when forage fish are not spawning. If working outside of a
designated work window, or if forage fish work windows are closed year round, work may occur if the
work window restriction is released for a period of time after a forage fish spawning survey has been
conducted by a biologist approved by the Washington State Department of Fish and Wildlife (WDFW).
Forage fish species with designated in -water work windows include Pacific sand lance (Ammodytes
hexapterus), Pacific herring (Clupea pallasi), and surf smelt (Hypomesus pretiosus). This RGC does not
15
apply to NWP 48, Commercial Shellfish Aquaculture Activities. Please see specific regional conditions
for NWP 48.
11. Notification of Permit Requirements: The permittee must provide a copy of the nationwide permit
authorization letter, conditions, and permit drawings to all contractors and any other parties performing
the authorized work prior to the commencement of any work in waters of the U.S. The permittee must
ensure all appropriate contractors and any other parties performing the authorized work at the project site
have read and understand relevant NWP conditions as well as plans, approvals, and documents referenced
in the NWP letter. A copy of these documents must be maintained onsite throughout the duration of
construction.
12. Construction Boundaries: Permittees must clearly mark all construction area boundaries before
beginning work on projects that involve grading or placement of fill. Boundary markers and/or
construction fencing must be maintained and clearly visible for the duration of construction. Permittees
should avoid and minimize removal of native vegetation (including submerged aquatic vegetation) to the
maximum extent possible.
13. Temporary Impacts and Site Restoration
a. Temporary impacts to waters of the U.S. must not exceed six months unless the prospective permittee
requests and receives a waiver by the district engineer. Temporary impacts to waters of the U.S. must
be identified in the PCN.
b. No more than 1/2 acre of waters of the U.S. may be temporarily filled unless the prospective permittee
requests and receives a waiver from the district engineer (temporary fills do not affect specified limits
for loss of waters associated with specific nationwide permits).
c. Native soils removed from waters of the U.S. for project construction should be stockpiled and used
for site restoration. Restoration of temporarily disturbed areas must include returning the area to pre -
project ground surface contours. If native soil is not available from the project site for restoration,
suitable clean soil of the same textural class may be used. Other soils may be used only if identified in
the PCN.
d. The permittee must revegetate disturbed areas with native plant species sufficient in number, spacing,
and diversity to restore affected functions. A maintenance and monitoring plan commensurate with
the impacts, may be required. Revegetation must begin as soon as site conditions allow within the
same growing season as the disturbance unless the schedule is approved by the Corps of Engineers.
Native plants removed from waters of the U.S. for project construction should be stockpiled and used
for revegetation when feasible. Temporary Erosion and Sediment Control measures must be removed
as soon as the area has established vegetation sufficient to control erosion and sediment.
e. If the Corps determines the project will result in temporary impacts of submerged aquatic vegetation
(SAV) that are more than minimal, a monitoring plan must be submitted. If recovery is not achieved
by the end of the monitoring period, contingencies must be implemented, and additional monitoring
will be required.
This RGC does not apply to NWP 48, Commercial Shellfish Aquaculture Activities. Please see specific
regional conditions for NWP 48.
D. CORPS REGIONAL SPECIFIC CONDITIONS FOR THIS NWPS: none
E. ECOLOGY 401 CERTIFICATION: GENERAL CONDITIONS
In addition to all the Corps National and Seattle Districts' Regional permit conditions, the following State
General Section 401 Water Quality Certification (Section 401) conditions apply to all Nationwide Permits
whether certified or partially certified in the State of Washington.
1. For in -water construction activities. Ecology Section 401 review is required for projects or
16
activities authorized under NWPs that will cause, or may be likely to cause or contribute to an exceedance
of a State water quality standard (Chapter 173-201A WAC) or sediment management standard (Chapter
173-204 WAC). State water quality standards and sediment management standards are available on
Ecology's website. Note: In -water activities include any activity within a wetland and/or activities below
the ordinary high water mark (OHWM).
2. Projects or Activities Discharging to Impaired Waters. Ecology Section 401 review is required for
projects or activities authorized under NWPs if the project or activity will occur in a 303(d) listed
segment of a waterbody or upstream of a listed segment and may result in further exceedances of the
specific listed parameter. To determine if your project or activity is in a 303(d) listed segment of a
waterbody, visit Ecology's Water Quality Assessment webpage for maps and search tools.
3. Application. For projects or activities that will require Ecology Section 401 review, applicants must
provide Ecology with a Joint Aquatic Resources Permit Application (JARPA) along with the
documentation provided to the Corps, as described in National General Condition 32, Pre -Construction
Notification, including, when applicable: (a) A description of the project, including site plans, project
purpose, direct and indirect adverse environmental effects the project would cause, best management
practices (BMPs), and any other Department of the Army or federal agency permits used or intended to be
used to authorize any part of the proposed project or any related activity. (b) Drawings indicating the
Ordinary High Water Mark (OHWM), delineation of special aquatic sites and other waters of the state.
Wetland delineations must be prepared in accordance with the current method required by the Corps and
shall include Ecology's Wetland Rating form. Wetland rating forms are subject to review and verification
by Ecology staff. Guidance for determining the OHWM is available on Ecology's website. (c) A
statement describing how the mitigation requirement will be satisfied. A conceptual or detailed mitigation
or restoration plan may be submitted. See State General Condition 5 for details on mitigation
requirements. (d) Other applicable requirements of Corps Nationwide Permit General Condition 32,
Corps Regional Conditions, or notification conditions of the applicable NWP. (e) Within 180 calendar
days from receipt of applicable documents noted above and a copy of the final authorization letter from
the Corps providing coverage for a proposed project or activity under the NWP Program Ecology will
provide the applicant notice of whether an individual Section 401 will be required for the project. If
Ecology fails to act within a year after receipt of both of these documents, Section 401 is presumed
waived.
4. Aquatic resources requiring special protection. Certain aquatic resources are unique, difficult -to -
replace components of the aquatic environment in Washington State. Activities that would affect these
resources must be avoided to the greatest extent possible. Compensating for adverse impacts to high
value aquatic resources is typically difficult, prohibitively expensive, and may not be possible in some
landscape settings. Ecology Section 401 review is required for activities in or affecting the following
aquatic resources (and not prohibited by Seattle District Regional General Condition): (a) Wetlands with
special characteristics (as defined in the Washington State Wetland Rating Systems for western and
eastern Washington, Ecology Publications #14-06-029 and #14-06-030):
• Estuarine wetlands.
• Wetlands of High Conservation Value.
• Bogs.
• Old -growth and mature forested wetlands.
• Wetlands in coastal lagoons.
• Interdunal wetlands.
• Vernal pools.
• Alkali wetlands.
(b) Fens, aspen -dominated wetlands, camas prairie wetlands. (c) Marine water with eelgrass (Zostera
marina) beds (except for NWP 48). (d) Category I wetlands. (e) Category II wetlands with a habitat score
> 8 points. This State General Condition does not apply to the following Nationwide Permits:
17
NWP 20 — Response Operations for Oil and Hazardous Substances, NWP 32 — Completed Enforcement
Actions
5. Mitigation. Applicants are required to show that they have followed the mitigation sequence and
have first avoided and minimized impacts to aquatic resources wherever practicable. For projects
requiring Ecology Section 401 review with unavoidable impacts to aquatics resources, adequate
compensatory mitigation must be provided.
(a) Wetland mitigation plans submitted for Ecology review and approval shall be based on the most
current guidance provided in Wetland Mitigation in Washington State, Parts 1 and 2 (available on
Ecology's website) and shall, at a minimum, include the following:
i. A description of the measures taken to avoid and minimize impacts to wetlands and other waters of
the U.S.
ii. The nature of the proposed impacts (i.e., acreage of wetlands and functions lost or degraded).
iii. The rationale for the mitigation site that was selected.
iv. The goals and objectives of the compensatory mitigation project.
v. How the mitigation project will be accomplished, including construction sequencing, best
management practices to protect water quality, proposed performance standards for measuring success
and the proposed buffer widths.
vi. How it will be maintained and monitored to assess progress towards goals and objectives.
Monitoring will generally be required for a minimum of five years. For forested and scrub -shrub
wetlands, 10 years of monitoring will often be necessary.
vii. How the compensatory mitigation site will be legally protected for the long term.
Refer to Wetland Mitigation in Washington State — Part 2: Developing Mitigation Plans (Ecology
Publication #06-06-01 lb) and Selecting Wetland Mitigation Sites Using a Watershed Approach (Ecology
Publications #09-06-032 (Western Washington) and #10-06-007 (Eastern Washington)) for guidance on
selecting suitable mitigation sites and developing mitigation plans. Ecology encourages the use of
alternative mitigation approaches, including credit/debit methodology, advance mitigation, and other
programmatic approach such as mitigation banks and in -lieu fee programs. If you are interested in
proposing use of an alternative mitigation approach, consult with the appropriate Ecology regional staff
person. Information on alternative mitigation approaches is available on Ecology's website.
(b) Mitigation for other aquatic resource impacts will be determined on a case -by -case basis.
6. Temporary Fills. Ecology Section 401 review is required for any project or activity with temporary
fill in wetlands or other waters of the state for more than 90 days, unless the applicant has received
written approval from Ecology. Note: This State General Condition does not apply to projects or activities
authorized under NWP 33, Temporary Construction, Access, and Dewatering
7. Stormwater pollution prevention: All projects that involve land disturbance or impervious surfaces
must implement stormwater pollution prevention or control measures to avoid discharge of pollutants in
stormwater runoff to waters of the State.
(a)For land disturbances during construction, the applicant must obtain and implement permits (e.g.,
Construction Stormwater General Permit) where required and follow Ecology's current stormwater
manual.
(b) Following construction, prevention or treatment of on -going stormwater runoff from impervious
surfaces shall be provided.
Ecology's Stormwater Management and Design Manuals and stormwater permit information are available
on Ecology's website.
8. State Section 401 Review for PCNs not receiving 45-day response from the Seattle District. In the
event the Seattle District Corps does not issue a NWP authorization letter within 45 calendar days of
receipt of a complete pre -construction notification, the applicant must contact Ecology for Section 401
review prior to commencing work.
18
F. ECOLOGY 401 CERTIFICATION: SPECIFIC CONDITIONS FOR THIS NWP:
