VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page 9 of 12
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strinizide.html.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Proposed construction does not require any mitigation.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet): 0.0
Amount of buffer mitigation requested (square feet): 0.0
Amount of Riparian wetland mitigation requested (acres): 0.0
Amount of Non-riparian wetland mitigation requested (acres): 0.0
Amount of Coastal wetland mitigation requested (acres): 0.0

X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ® No ? If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Zone* Impact
(square feet) Multiplier Required
Mitigation

Eagle Ridge - Phase 8B
Garner, North Carolina
Storm Water Calculations
Addendum Report
General Description
The Eagle Ridge - Phase 8B development is located off Old Stage Road Garner, NC.
The project is a proposed single family subdivision. The existing topography of this site
splits drainage flow into three directions. The existing draw on the north side of the
property drains approximately half the site. The existing draw to the east drains
approximately a quarter of the site and the remaining quarter of the site drains to the
existing lake on the west side of the site. The property is open field with only a few trees
and includes the exiting lake. The proposed storm sewer will collect the stormwater and
convey it to the existing lake on the west side of the site through one discharge point. At
the discharge point a weir box is proposed to direct the 1 "/hr storm to a level spreader
and allow larger storms to bypass. The 1"/hr storm drainage is directed to the level
spreader which has been sized at the 13 linear feet per 1 cubic foot per second of flow,
according to the Neuse Buffer Rules.
The enclosed plans and report detail the diffused flow design for the stormwater drainage
from the Phase 8B parcel and support the effort to attain non-erosive velocities through
the Neuse River Buffer. The level spreader has been designed according to the NCDENR
Division of Water Quality Draft Level Spreader Design Options Version 1.0.

LEVEL SPREADER OPERATION AND MAINTENANCE AGREEMENT
The level spreader system is defined as the bypass junction box, the level spreading slotted
drain and associated pipe and the bypass outlet pipe.
Maintenance activities shall be performed as follows:
Every six months:
a. Inspect the level spreader system for sediment accumulation, erosion, trash
accumulation, vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that the full length of the level
spreader functions as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover,
mow vegetative cover to maintain a maximum height of six inches, and remove trash as
needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.)
quarterly to maintain proper functioning.
4. Remove accumulated sediment from the level spreader system semi-annually using
cleanout structures at the end of each length of level spreader. Removed sediment shall
be disposed of in an appropriate manner and shall be handled in a manner that will not
adversely impact water quality (i.e. stockpiling near a stream, pond, etc.).
5. All components of the level spreader system shall be maintained in good working order.
6. A level elevation shall be maintained across the entire flow spreading structure. Any down
gradient erosion must be repaired and/or replanted as necessary.
I acknowledge and agree by my signature below that I am responsible for the performance of
the seven maintenance procedures listed above. I agree to notify DWQ of any problems with
the system or prior to any changes to the system or responsible party.

i Eagle Ridge - Phase 8B
Garner, North Carolina
Storm Water Calculations
Addendum Report
General Description
The Eagle Ridge - Phase 8B development is located off Old Stage Road Garner, NC.
The project is a proposed single family subdivision. The existing topography of this site
splits drainage flow into three directions. The existing draw on the north side of the
property drains approximately half the site. The existing draw to the east drains
approximately a quarter of the site and the remaining quarter of the site drains to the
existing lake on the west side of the site. The property is open field with only a few trees
and includes the exiting lake. The proposed storm sewer will collect the stormwater and
• convey it to the existing lake on the west side of the site through one discharge point. At
the discharge point a weir box is proposed to direct the 1"/hr storm to a level spreader
and allow larger storms to bypass. The 1"/hr storm drainage is directed to the level
spreader which has been sized at the 13 linear feet per 1 cubic foot per second of flow,
according to the Neuse Buffer Rules.
The enclosed plans and report detail the diffused flow design for the stormwater drainage
from the Phase 8B parcel and support the effort to attain non-erosive velocities through
the Neuse River Buffer. The level spreader has been designed according to the NCDENR
Division of Water Quality Draft Level Spreader Design Options Version 1.0.

DEPARTMENT OF THE ARMY
CORPS OF ENGINEERS
FINAL NOTICE OF ISSUANCE AND MODIFICATION OF NATIONWIDE PERMITS
FEDERAL REGISTER
MARCH 9, 2000
Maintenance: Activities related to:
W 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 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 cue
to changes in materials, construction techniques, or current construction codes or safety
standards which are necessary to make repair, rehabilitation, or replacement, are permitted,
provided the adverse environmental effects resulting from such repair, rehabilitation, or
replacement are minimal. Currently serviceable means useable as is or with some maintenance,
but not so degraded as to essentially require reconstruction. This nationwide permit 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.
(ii) Discharges of dredged or fill material, including excavation, into all waters of the United
States to remove accumulated sediments and debris in the vicinity of, and within, existing
structures (e.g., bridges, culverted iroad crossings, water intake structures, etc.) and the placement
of new or additional rip rap to protect the structure, provided the permittee notifies the District
Engineer in accordance with General Condition 13. The removal of sediment is limited to the
minimum necessary to restore the waterway in the immediate vicinity of the structure to the
approximate dimensions that existed when the structure was built, but cannot extend further than
200 feet in any direction from the structure. The placement of rip rap must be the minimum
necessary to protect the structure or to ensure the safety of the structure. All excavated materials
must be deposited and retained in an upland area unless otherwise specifically approved by the
District Engineer under separate authorization. Any bank stabilization measures not directly
associated with the structure will require a separate authorization from the District Engineer.
Oct 10 03 12:33p Spangler Environmental 9195460757 p.5
(iii) Discharges of dredged or fill material, including excavation, into all %vatcrs of tlic United
-States for activities associated with the restoration of upland areas damaged by a storm, flood, or
other discrete event, including the construction, placement, or installation of upland protcetion
structures and minor dredging to remove obstructions in waters of the United States. (Uplands
lost as a result of a storm, flood, or other discrete event can be rcplaced without a Section 404
permit provided the uplands arc restored to their ori ginal pre-event location. This NWP is for the
activities in waters of the United States associated with the replacement of the uplands.) The
pen=iittee must notify the District Engineer, in accordance with General Condition 13, within 12
months of the date of the damage and the work must commence, or be under contract to
commence, within two years of the date of the damage. The permittee should provide evidence,
such as a recent topographic survey or photographs, to justify the extent of the proposed
restoration. The restoration of the damaged areas cannot exceed the contours, or ordinary high
water mark, that existed prior to the damage. The District Engineer retains the right to detcrrriine
the extent of the pre-existing conditions and the extent of any restoration work authorized by this
permit. Minor dredging to remove obstructions from the adjacent waterbody is limited to 50
cubic yards below the plane of the ordinary high water mark, and is limited to the amount
necessary to restore the pre-existing bottom contours of the waterbody. The dredging may not be
done primarily to obtain fill for any restoration activities. The discharge of dredged or fill
material and all related work needed to restore the upland must be part of a single and complete
project. This permit cannot be used in conjunction with NWP 18 or NWP 19 to restore damaged
upland areas. This permit does not authorize the replacement of lands lost through gradual .
erosion processes.
Maintenance dredging for the primary purpose of navigation and beach restoration are not
authorized by this permit. This permit does not authorize new stream channelization or stream
relocation projects. Any work authorized by this permit must not cause more than minimal
degradation of water quality, more than minimal changes to the flow characteristics of the
stream, or increase flooding (See General Conditions 9 and 21). (Sections 10 and 404)
Note: This NWP authorizes the minimal impact repair, rehabilitation, or replacement of any
previously authorized structure or fill that does not qualify for the Section 404(f) exemption for
maintenance.
Oct 10 03 12:34p Spangler Environmental 9195460757 p.6
NATIONWIDE PERMIT #3: MAINTENANCE
Section 10 and 404
NATIONWIDE PERMIT CONDITIONS
1. Navigation. No activity may cause more than a minimal adverse effect on navigation.
2. Proper Maintenance. Any structure or fill authorized shall be properly maintained, including
maintenance to ensure public safety.
3. 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.
4. Aquatic Life Movements. No activity may substantially disrupt the movement of those
species of aquatic life indigenous to the waterbody, including those species which normally
migrate through the area, unless the activity's primary purpose is to impound water. Culverts
placed in streams must be installed to maintain low flow conditions.
5. Equipment. Heavy equipment working in wetlands must be placed on mats, or other
measures must be taken to minimize soil disturbance.
6. Regional and Case-By-Case Conditions. The activity must comply with any regional
conditions which 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 or tribe in its Section 401 water
quality certification and Coastal Zone Management Act consistency determination.
7. 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 effect 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 in the area (e.g., National Park Service, U.S. Forest
Service, Bureau of Land Management, U.S. Fish and Wildlife Service.)
8. Tribal rights. No activity or its operation may impair reserved tribal rights, including, but not
limited to, reserved water rights and treaty fishing and hunting rights.
9. Water Quality Certification. The permitter must comply with all conditions of General
Water Quality Certification No. 3290, issued by the North Carolina Division of Water Quality
(NCDWQ) on June 1, 2000.
Oct 10 03 12:34p Spangler Environmental 9195460757 p.7
10. Coastal Zone Management. The North Carolina Division of Coastal Management
(NCDCM), has waived consistency.
11. Endangered Species.
a. No activity is authorized under any NWP which is likely to 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, or which is likely to destroy or adversely
modify the critical habitat of such species. Non-Federal permittees shall notify the District
Engineer if any listed species or designated critical habitat might be affected or is in the vicinity
of the project, or is located in the designated critical habitat and shall not begin work on the
activity until notified by the District Engineer that the requirements of the Endangered Species
Act have been satisfied and that the activity is authorized. For activities that may affect
Federally-listed endangered or threatened species or designated critical habitat, the notification
must include the name(s) of the endangered or threatened species that may be affected by the
proposed work or that utilize the designated critical habitat that may be affected by the proposed
work. 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 NWP's.
b. Authorization of an activity by a NWP does not authorize the "take" of a
threatened or endangered species as defined under the Federal Endangered Species Act.
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. Fish and Wildlife Service
or the National Marine Fisheries Service, both lethal and nonlethal "takes" of protected
species are in violation of the Endangered Species Act. Information on the location of
threatened and endangered species and their critical habitat can be obtained directly
from the offices of the U.S. Fish and Wildlife Service and National Marine Fisheries
Service or their world wide web pages at http://www.fws.gov/r9endspp/endspp.html and
http://nfrns.gov/prot-res/esahome.html, respectively.
12. Historic Properties. No activity which may affect historic properties listed, or eligible for
listing, in the National Register of Historic Places is authorized, until the District Engineer has
complied with the provisions of 33 CFR part 325, Appendix C. The prospective permittee must
notify the District Engineer if the authorized activity may affect any historic properties listed,
determined to be eligible, or which the prospective permittee has reason to believe may be
eligible for listing on the National Register of Historic Places, and shall not begin the activity
until notified by the District Engineer that the requirements of the National Historic Preservation
Act have been satisfied and that the activity is authorized. Information on the location and
existence of historic resources can be obtained from the State Historic Preservation Office and
the National Register of Historic Places (see 33 CFR 330.4(8)). For activities that may affect
historic properties listed in, or eligible for listing in, the Irrational Register of Historic Places, the
notification must state which historic property may be affected by the proposed work or include
a vicinity map indicating the location of the historic property.
13. Notification:
Oct 10 03 12:35p Spangler Environmental 9195460757 p.8
a. Timing. Where required by the terms of the NWP, the prospective permittee must notify
the District Engineer with a PreConstruction Notification (PCN) as early as possible. The
District Engineer must determine if the PCN is complete within 30 days of the date of receipt
and can request the 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:
(1) Until 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) If notified by the District or Division Engineer that an individual permit is required;
or
(3) Unless 45 days have passed from the District Engineer's receipt of the complete
notification and the prospective permittee has not received written notice from the District or
Division Engineer. 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); and
b. Contents of notification. The notification 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; and
(3) Brief description of the proposed project; the project's purpose; direct and indirect
adverse environmental effects the project would cause; and 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.
c. Form of Notification: The standard individual permit application form (Form ENG 4345)
may be used as the notification but must clearly indicate that it is a PCN and must include all the
information required in b.(1)-(3) of General Condition 13. A letter containing the requisite
information may also be used.
d. District Engineer's Decision: 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. The prospective permittee may, optionally, submit a proposed mitigation plan with the
PCN to expedite the process and 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 work are minimal. If the
District Engineer determines that the activity complies with the terms and conditions of the NWP
Oct 10 03 12:35p Spangler Environmental 9195460757 p.9
and that the effects on the aquatic environment are minimal, the District Engineer will notify the
permittee and include any conditions the District Engineer deems necessary.
Any compensatory mitigation proposal must be approved by the District Engineer prior to
commencing work. If the prospective permittee is required to submit a compensatory mitigation
proposal with the PCN, the proposal may be either conceptual or detailed. 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 plan within 45 days of receiving a complete PCN and determine whether the
conceptual or specific 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 stating that the project can proceed under the terms and conditions of the nationwide--
permit.
If the District Engineer determines that the adverse effects of the proposed work are more
than minimal, then he will notify the applicant either:
(1) 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:
(2) that the project is authorized under the NWP subject to the applicant's submission of
a mitigation proposal that would reduce the adverse effects on the aquatic environment to
the minimal level; or
(3) that the project is authorized under the N1 WP with specific modifications or
conditions.
Where the District Engineer determines that mitigation is required in order to ensure no
more than minimal adverse effects on the aquatic environment, the activity will be authorized
within the 45-day PCN period, including the necessary conceptual or specific mitigation or a
requirement that the applicant submit a mitigation proposal that would reduce the adverse effects
on the aquatic environment to the minimal level. When conceptual mitigation is included, or a
mitigation plan is required under item (2) above, no work in waters of the United States will
occur until the District Engineer has approved a specific mitigation plan.
e. Agency Coordination. The District Engineer will consider any comments from Federal
and State agencies. eoncerning the proposed activity's compliance with the terms and conditions
of the NWPs and the need for mitigation to reduce the project's adverse effects on the aquatic
environment to a minimal level.
For activities requiring notification to the District Engineer that result in the loss of greater
than %Z acre of waters of the United States, the District Engineer will, upon receipt of a
notification, provide immediately (e.g., via facsimile transmission, overnight mail, or other
expeditious manner), a copy to the appropriate offices of the Nish and Wildlife Service, State
Oct 10 03 12:36p Spangler Environmental 9195460757 p.10
natural resource or water quality agency, FTIA. State Historic Presentation Officer (SHPO), and,
if appropriate, the National Marine Fisheries Service. i PVith the exception of.,V1VP 37J 't'hese
agencies will then 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.
If so contacted by an agency, the District Engineer will wait an additional 15 calendar days
before making a decision on the notification. The District Engineer will fully consider agency
comments received within the specified time frame, but will provide no response to the resource
agency, except as provided below. The District Engineer will indicate in the administrative
record associated with each notification that the resource agencies' concerns were considered.
As required by Section 305(b)(4)(B) of the Magnuson-Stevens Fishery Conservation and
Management Act, the District Engineer will provide a response to National Marine Fisheries
Service within 30 days of receipt of any Essential Fish Habitat consentation recommendations.
Applicants are encouraged to provide the Corps multiple copies of notifications to expedite
agency notification.
f. Wetlands Delineations. Welland 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 site. There may be some delay if the Corps does the delineation. Furthermore, the 45-
day period will not start until the wetland delineation has been completed and submitted to the
Corps, where appropriate.
g. For activities that may adversely affect Federally-listed endangered or threatened species,
the PCN must include the name(s) of those endangered or threatened species that may be
affected by the proposed work or utilize the designated critical habitat that may be attected by
the proposed work.
h. For activities that may affect historic properties listed in, or eligible for listing in, the
National Register of Historic Places, 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.
i. For activities that may adversely affect Federally-listed endangered or threatened species,
the PCN must include the name(s) of those endangered or threatened species that may be
affected by the proposed work or utilize the designated critical habitat that may be attected by
the proposed work.
j. For activities that may affect historic properties listed in, or eligible for listing in, the
National Register of Historic Places, 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.
14. Compliance Certification. Every permittee who has received a Nationwide permit
verification from the Corps will submit a signed certification regarding the completed work and
any required mitigation. The certification will be forwarded by the Corps with the authorization
letter. The certification will include:
a. A statement that the authorized work was done in accordance with the Corps
authorization, including any general or specific conditions;
Oct 10 03 12:36p Spangler Environmental 9195460757 p.il
b. A statement that any required mitigation was completed in accordance with the permit
conditions. and
c. The signature of the perrnittee certifying the completion of the work and mitigation.
15. 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-
16. Water Supply Intakes. No activity, including structures and work- in navigable waters ofthe
United States or discharges of dredged or fill material, may occur in the proximity of a public
water supply intake except where the activity is for repair of the public water supply intake
structures or adjacent bank stabilization.
17. Shellfish Beds. No activity, including structures and work in navigable waters of the United
States or discharges of dredged or fill material, may occur in areas of concentrated shellfish
populations, unless the activity is directly related to a shellfish harvesting activity authorized by
NWP 4.
18. Suitable Material. No activity, including structures and work in navigable waters of the
United States or discharges of dredged or fill material, may consist of unsuitable material (e.g.,
trash, debris, car bodies, asphalt, etc.) and material used for construction or discharged must be
free from toxic pollutants in toxic amounts (see Section 307 of the Clean Water Act).
19. Mitigation. The project must be designed and constructed to avoid and minimize adverse
effects to waters of the United States to the maximum extent practicable at the project site (i.e.,
on site). Mitigation will be required when necessary to ensure that the adverse effects to the
aquatic environment are minimal. The District Engineer will consider the factors discussed
below when determining the acceptability of appropriate and practicable mitigation necessary to
offset adverse effects on the aquatic environment that are more than minimal
a. Compensatory mitigation at a minimum 1:1 ratio will be required for all wetland impacts
requiring a PCN. Consistent with National Policy, the District Engineer will establish a
preference for restoration of wetlands to meet the minimum compensatory mitigation ratio, with
preservation used only in exceptional circumstances.
b. To he practicable, the mitigation must be available and capable of being done considering
costs, existing technology, and logistics in light of the overall project purposes. Examples of
mitigation that may be appropriate and practicable include, but are not limited to: reducing the
size of the project; establishing and maintaining wetland or upland vegetated buffers to protect
open waters such as streams; and replacing losses ofaquatic resource functions and values by
Oct 10 03 12:37p Spangler Environmental 9195460757 p.12
creating, restoring, enhancing, or preserving similar functions and values, preferably in the same
watershed:
c. The District Engineer will require restoration, creation, enhancement, or preservation of
other aquatic resources in order to offset the authorized impacts to the extent necessary to ensure
that the adverse effects on the aquatic environment are minimal. An important element of any
compensatory mitigation plan for projects in or near streams or other open waters is the
establishment and maintenance, to the maximum extent practicable, of vegetated buffers next to
open waters on the project site. The vegetated buffer should consist of native species. The
District Engineer will determine the appropriate width of the vegetated buffer and in which cases
it will be required. Normally, the vegetated buffer will be 25 to 50 feet wide on each side of the
stream, but the District Engineer may require wider vegetated buffers to address documented
water quality concerns. If there are open waters on the project site and the District Engineer
requires compensatory mitigation for wetland impacts to ensure that the net adverse effects on
the aquatic environment are minimal, any vegetated buffer will comprise no more than 1/3 of the
remaining compensatory mitigation acreage after the permanently filled wetlands have been
replaced on a one-to-one acreage basis. In addition, compensatory mitigation must address
adverse effects on wetland functions and values and cannot be used to offset the acreage of
wetland losses that would occur in order to meet the acreage limits of some of the NWPs (e.g.,
for NWP 39, %4 acre of wetlands cannot be created to change a %z acre loss of wetlands to a''/4
acre loss; however, %z acre of created wetlands can be used to reduce the impacts of-a 1/3 acre
loss of wetlands). If the prospective permittee is required to submit a compensatory mitigation
proposal with the PCN, the proposal may be either conceptual or detailed.
d. To the extent appropriate, permittees should consider mitigation banking and other
appropriate forms of compensatory mitigation. If the District Engineer determines that
compensatory mitigation is necessary to offset losses of waters of the United States and ensure
that the net adverse effects of the authorized work on the aquatic environment are minimal,
consolidated mitigation approaches, such as mitigation banks, will be the preferred method of
providing compensatory mitigation, unless the District Engineer determines that activity-specific
compensatory mitigation is more appropriate, based on which is best for the aquatic
environment. These types of mitigation are preferred because they involve larger blocks of
protected aquatic environment, are more likely to meet the mitigation goals, and are more easily
checked for compliance. If a mitigation bank or other consolidated mitigation approach is not
available in the water shed., the District Engineer will consider other appropriate forms of
compensatory mitigation to offset the losses of waters of the United States to ensure that the net
adverse effects of the authorized work on the aquatic environment are minimal.
20. Spawning Areas. Activities, including structures and work in navigable waters of the United
States or discharges of dredged or fill material, in spawning areas during spawning seasons must
be avoided to the maximum extent practicable. Activities that result in the physical destruction
(e.g., excavate, fill, or smother downstream by substantial turbidity) of an important spawning
area are not authorized.
21. Management of Water Flows. To the maximum extent practicable, the activity must be
designed to maintain preconstruction downstream (Tow conditions (e.g., location, capacity, and
Oct 10 03 12:38p Spangler Environmental 9195460757 p.13
flow rates). Furthermore, the activity must not permanently restrict or impede the passage of
non-nal or expected high flows (unless the primary purpose of the fill is to impound waters) and
the structure or discharge of dredged or fill material must withstand expected high flows. The
activity must, to the maximum extent practicable, provide for retaining excess flows from the
site, provide for maintaining surface flow rates from the site similar to preconstruction
conditions, and must not increase water flows from the project site, relocate water, or redirect
water flow beyond preconstruetion conditions. In addition, the activity must, to the maximum
extent practicable, reduce adverse effects such as flooding or erosion downstream and upstream
of the project site, unless the activity is part of a larger system designed to manage water !lows.
22. Adverse Effects From Impoundments. If the activity, including structures and work in
navigable waters of the United States or discharge of dredged or fill material, creates an
impoundment of water, adverse effects on the aquatic system caused by the accelerated passage
of water and/or the restriction of its flow shall be minimized to the maximum extent practicable-
23. Waterfowl Breeding Areas. Activities, including structures and work in navigable waters of
the United States or discharges of dredged or fill material, into breeding areas for migratory
waterfowl must be avoided to the maximum extent practicable.
24. Removal of Temporary Fills. Any temporary fills must be removed in their entirety and the
affected areas returned to their preexisting elevation.
25. Designated Critical Resource Waters. Critical resource waters include, NOAA-designated
marine sanctuaries, National Estuarine Research Reserves, National Wild and Scenic Rivers,
critical habitat for Federally listed threatened and endangered species, coral reefs, State natural
heritage sites, and outstanding national resource waters or other waters officially designated by a
State as having particular environmental or ecological significance and identified by the District
Engineer after notice and opportunity for public comment.
Notification is required in accordance with General Condition 13, 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 he determines that the
impacts to the critical resource waters will be no more than minimal.
26. Fills Within 100-Year FloodpIains. For purposes of this general condition i 00-year
floodplains will be identified through the Federal Emergency Management Agency" (FEMA)
Flood Insurance Rate Maps or FEMA-approved local floodpiain maps.
27. The permitee 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 pennittee
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.

FINAL NOTICE OF ISSUANCE AND MODIFICATION OF NATIONWIDE PERMITS
FEDERAL REGISTER
MARCH 9, 2000
Maintenance: Activities related to:
W 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 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 d-uc-
to changes in materials, construction techniques, or current construction codes or safety
standards which are necessary to make repair, rehabilitation, or replacement, are permitted,
provided the adverse environmental effects resulting from such repair, rehabilitation, or
replacement are minimal. Currently serviceable means useable as is or with some maintenance,
but not so degraded as to essentially require reconstruction. This nationwide permit 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.
(ii) Discharges of dredged or fill material, including excavation, into all waters of the United
States to remove accumulated sediments and debris in the vicinity of, and within, existing
structures (e.g., bridges, culverted road crossings, water intake structures, etc.) and the placement
of new or additional rip rap to protect the structure, provided the permittee notifies the District
Engineer in accordance with General Condition 13. The removal of sediment is limited to the
minimum necessary to restore the waterway in the immediate vicinity of the structure to the
approximate dimensions that existed when the structure was built, but cannot extend further than
200 feet in any direction from the structure. The placement of rip rap must be the minimum
necessary to protect the structure or to ensure the safety of the structure. All excavated materials
must be deposited and retained in an upland area unless otherwise specifically approved by the
District Engineer under separate authorization. Any bank stabilization measures not directly
associated with the structure will require a separate authorization from the District Engineer-
Oct 10 03 12:33p Spangler Environmental 9195460757 p.5
liii) Discharges of dredged or fill material, including; excavation, into all waters of the United
States for activities associated with the restoration of upland areas damaged by a storm, flood, or
other discrete event, including the construction, placement, or installation of upland protection
structures and minor dredging to remove obstructions in waters of the United States. (Uplands
lost as a result of a storm, flood, or other discrete event can be replaced without a Section 404
permit provided the uplands are restored to their original pre-event location. This N WP is for the
activities in waters of the United States associated with the replacement of the uplands.) The
pc rnittec must notify the District Engineer, in accordance with General Condition 13, within 12
months of the date of the damage and the work must commence, or be under contract to
commence, within two years of the date of the damage. The permittee should provide evidence,
such as a recent topographic survey or photographs, to justify the extent of the proposed
restoration. The restoration of the damaged areas cannot exceed the contours, or ordinary high
water mark, that existed prior to the damage. The District Engineer retains the right to determine
the extent of the pre-existing conditions and the extent of any restoration work authorized by this
permit. Minor dredging to remove obstructions from the adjacent waterbody is limited to 50
cubic yards below the plane of the ordinary high water mark, and is limited to the amount
necessary to restore the pre-existing bottom contours of the waterbody. The dredging may not be
done primarily to obtain fill for any restoration activities. The discharge of dredged or fill
material and all related work needed to restore the upland must be part of a single and complete
project. This permit cannot be used in conjunction with NWP 18 or NWP 19 to restore damaged
upland areas. This permit does not authorize the replacement of lands lost through gradual .
erosion processes.
Maintenance dredging for the primary purpose of navigation and beach restoration are not
authorized by this permit. This permit does not authorize new stream channelization or stream
relocation projects. Any work authorized by this permit must not cause more than minimal
degradation of water quality, more than minimal changes to the flow characteristics of the
stream, or increase flooding (See General Conditions 9 and 21). (Sections 10 and 404)
Vote: This NWP authorizes the minimal impact repair, rehabilitation, or replacement of any
previously authorized structure or fill that does not qualify for the Section 404(f) exemption for
maintenance.

NATIONWIDE PERMIT 0: MAINTENANCE
Section 10 and 404
NATIONWIDE PERMIT CONDITIONS
I . Navigation. No activity may cause more than a minimal adverse effect on navigation.
2. Proper Maintenance. Any structure or fill authorized shall be properly maintained, including
maintenance to ensure public safety.
3. 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.
4. Aquatic Life Movements. No activity may substantially disrupt the movement of those
species of aquatic life indigenous to the waterbody, including those species which normally
migrate through the area, unless the activity's primary purpose is to impound water. Culverts
placed in streams must be installed to maintain low flow conditions.
5. Equipment. Heavy equipment working in wetlands must be placed on mats, or other
measures must be taken to minimize soil disturbance.
6. Regional and Case-By-Case Conditions. The activity must comply with any regional
conditions which 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 or tribe in its Section 401 water
quality certification and Coastal Zone Management Act consistency determination.
7. 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 effect 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 in the area (e.g., National Park Service, U.S. Forest
Service, Bureau of Land Management, U.S. Fish and Wildlife Service.)
8. Tribal rights. No activity or its operation may impair reserved tribal rights, including, but not
limited to, reserved water rights and treaty fishing and hunting rights.
9. Water Quality Certification. The permitter must comply with all conditions of General
Water Quality Certification No. 3290, issued by the North Carolina Division of Water Quality
(NCDWQ) on June 1, 2000.
Oct 10 03 12:34p Spangler Environmental 9195460757 p.7
10. Coastal Zone Management. The North Carolina Division of Coastal Management
(NCDCM), has waived consistency.
11. Endangered Species.
a. No activity is authorized under any NWP which is likely to 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, or which is likely to destroy or adversely
modify the critical habitat of such species. Non-Federal permittees shall notify the District
Engineer if any listed species or designated critical habitat might be affected or is in the vicinity
of the project, or is located in the designated critical habitat and shall not begin work on the
activity until notified by the District Engineer that the requirements of the Endangered Species
Act have been satisfied and that the activity is authorized. For activities that may affect
Federally-listed endangered or threatened species or designated critical habitat, the notification
must include the name(s) of the endangered or threatened species that may be affected by the
proposed work or that utilize the designated critical habitat that may be affected by the proposed
work. 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 NWP's.
b. Authorization of an activity by a NWP does not authorize the "take" of a
threatened or endangered species as defined under the Federal Endangered Species Act.
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. Fish and Wildlife Service
or the National Marine Fisheries Service, both lethal and non-lethal "takes" of protected
species are in violation of the Endangered Species Act. Information on the location of
threatened and endangered species and their critical habitat can be obtained directly
from the offices of the U.S. Fish and Wildlife Service and National Marine Fisheries
Service or their world wide web pages at http://www.fws.gov/r9endspp/endspp.htznl and
http://nf ns.gov/prot res/esahome.htmL respectively.
12. Historic Properties. No activity which may affect historic properties listed, or eligible for
listing, in the National Register of Historic Places is authorized, until the District Engineer has
complied with the provisions of 33 CFR part 325, Appendix C. The prospective permittee must
notify the District Engineer if the authorized activity may affect any historic properties listed,
determined to be eligible, or which the prospective pennittee has reason to believe may be
eligible for listing on the National Register of Historic Places, and shall not begin the activity
until notified by the District Engineer that the requirements of the National Historic Preservation
Act have been satisfied and that the activity is authorized. Information on the location and
existence of historic resources can be obtained from the State Historic Preservation Office and
the National Register of Historic Places (see 33 CFR 330.4(8)). For activities that may affect
historic properties listed in, or eligible for listing in, the National Register of Historic Places, the
notification must state which historic property may be affected by the proposed work or include
a vicinity map indicating the location of the historic property.
13. Notification:
Oct 10 03 12:35p Spangler Environmental 9195460757 p.8
a. Timing. Where required by the terms of the NWP, the prospective penmittee must notify
the District Engineer with a PreConstruction Notification (PCN) as early as possible. The
District Engineer must determine if the PCN is complete within 30 days of the date of receipt
and can request the 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:
(1) Until 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) If notified by the District or Division Engineer that an individual permit is required;
or
(3) Unless 45 days have passed from the District Engineer's receipt of the complete
notification and the prospective permittee has not received written notice from the District or
Division Engineer. 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); and
b. Contents of notification. The notification 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; and
(3) Brief description of the proposed project; the project's purpose; direct and indirect
adverse environmental effects the project would cause; and 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.
c. Form of Notification: The standard individual permit application form (Form ENG 4345)
may be used as the notification but must clearly indicate that it is a PCN and must include all the
information required in b.(1)-(3) of General Condition 13. A letter containing the requisite
information may also be used.
d. District Engineer's Decision: 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. The prospective permitter may, optionally, submit a proposed mitigation plan with the
PCN to expedite the process and 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 work arc minimal. If the
District Engineer determines that the activity complies with the terms and conditions of the NWP
Oct 10 03 12:35p Spangler Environmental 9195460757 p,9
and that the effects on the aquatic environment are minimal, the District Engineer will notify the
permittee and include any conditions the District Engineer deems necessary.
Any compensatory mitigation proposal must be approved by the District Engineer prior to
commencing work. If the prospective permittee is required to submit a compensatory mitigation
proposal with the PCN, the proposal may be either conceptual or detailed. If the prospectiv:
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 plan within 45 days of receiving a complete PC.N and determine whether the
conceptual or specific 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 stating that the project can proceed under the terms and conditions of the nationwide--
permit.
If the District Engineer determines that the adverse effects of the proposed work are more
than minimal, then he will notify the applicant either:
(1) 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:
(2) that the project is authorized under the NWP subject to the applicant's submission of
a mitigation proposal that would reduce the adverse effects on the aquatic environment to
the minimal level; or
(3) that the project is authorized under the N'WP with specific modifications or
conditions.
Where the District Engineer determines that mitigation is required in order to ensure no
more than minimal adverse effects on the aquatic environment, the activity will be authorized
within the 45-day PCN period, including the necessary conceptual or specific mitigation or a
requirement that the applicant submit a mitigation proposal that would reduce the adverse effects
on the aquatic environment to the minimal level. When conceptual mitigation is included, or a
mitigation plan is required under item (2) above, no work in waters of the United States will
occur until the District Engineer has approved a specific mitigation plan.
e. Agency Coordination. The District Engineer will consider any comments from Federal
and State agencies concerning the proposed activity's compliance with the teRns and conditions
of the NWPs and the need for mitigation to reduce the project's adverse effects on the aquatic
environment to a minimal level.
For activities requiring notification to the District Engineer that result in the loss of greater
than %2 acre of waters of the United States, the District Engineer will, upon receipt of a
notification, provide immediately (e.g., via facsimile transmission, overnight mail, or other
expeditious manner), a copy to the appropriate offices of the Fish and Wildlife Service, State
Oct 10 03 12:36p Spangler Environmental 9195460757 p.10
natural resource; or water quality agency, F.1'A. State Historic Preservation Officer (SHPO), and,
if appropriate, the National Marine Fisheries Service. i 6Vith the exception of NIP 37,e 't'hese
agencies will then 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.
If so contacted by an agency, the District Engineer will wait an additional 15 calendar days
before making a decision on the notification. The District Engineer will fully consider agency
comments received within the specified time frame, but will provide no response to the resource
agency, except as provided below. The District Engineer will indicate in the administrative
record associated with each notification that the resource agencies' concerns were considered.
As required by Section 305(b)(4)(B) of the Magnuson-Stevens Fishery Conservation and
Management Act, the District Engineer will provide a response to National Marine Fisheries
Service within 30 days of receipt of any Essential Fish Habitat conservation recommendations.
Applicants are encouraged to provide the Corps multiple copies of notifications to expedite
agency notification.
f. Wetlands Delineations. Weiland delineations must be prepared in accordance with the
current method required by the Corps. The pennittee may ask the Corps to delineate the special
aquatic site. There may be some delay if the Corps does the delineation. Furthermore, the 45-
day period will not start until the wetland delineation has been completed and submitted to the
Corps, where appropriate.
g. For activities that may adversely affect Federally-listed endangered or threatened species,
the PCN must include the name(s) of those endangered or threatened species that may be
affected by the proposed work or utilize the designated critical habitat that may be affected by
the proposed work.
h. For activities that may affect historic properties listed in, or eligible for listing in, the
National Register of Historic Places, 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.
i. For activities that may adversely affect Federally-listed endangered or threatened species,
the PCN must include the name(s) of those endangered or threatened species that may be
affected by the proposed work or utilize the designated critical habitat that may be affected by
the proposed work.
j. For activities that may affect historic properties listed in, or eligible for listing in, the
National Register of Historic Places, 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.
14. Compliance Certification. Every permittee who has received a Nationwide permit
verification from the Corps will submit a signed certification regarding the completed work and
any required mitigation. The certification will be forwarded by the Corps with the authorization
letter. The certification will include:
a. A statement that the authorized work was done in accordance with the C ores
authorization, including any general or specific conditions;
Oct 10 03 12:36p Spangler Environmental 9195460757 p.ll
b. A statement that anv required mitigation was completed in accordance with the permit
conditions; and
c. The signature of the permittee certifying the completion of the work and mitigation.
15. 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 N TWP 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.
16. Water Supply Intakes. No activity, including structures and work- in navigable waters oi'the
United States or discharges of dredged or fill material, may occur in the proximity of a public
water supply intake except where the activity is for repair of the public water supply intake
structures or adjacent bank stabilization.
17. Shellfish Beds. No activity, including structures and work in navigable waters of the United
States or discharges of dredged or fill material, may occur in areas of concentrated shellfish
populations, unless the activity is directly related to a shellfish harvesting activity authorized by
NWP 4.
18. Suitable Material. No activity, including structures and work in navigable waters of the
United States or discharges of dredged or fill material, may consist of unsuitable material (e.g.,
trash, debris, car bodies, asphalt, etc.) and material used for construction or discharged must be
free from toxic pollutants in toxic amounts (see Section 307 of the Clean Water Act).
19. Mitigation. The project must be designed and constructed to avoid and minimize adverse
effects to waters of the United States to the maximum extent practicable at the project site (i.e.,
on site). Mitigation will be required when necessary to ensure that the adverse effects to the
aquatic environment are minimal. The District Engineer will consider the factors discussed
below when determining the acceptability of appropriate and practicable mitigation necessary to
offset adverse effects on the aquatic environment that are more than minimal
a. Compensatory mitigation at a minimum 1:1 ratio will be required for all wetland impacts
requiring a PCN. Consistent with National Policy, the District Engineer will establish a
preference for restoration of wetlands to meet the minimum compensatory mitigation ratio, with
preservation used only in exceptional circumstances.
b. To be practicable, the mitigation must be available and capable of being done considering
costs, existing technology, and logistics in light of the overall project purposes. Examples of
mitigation that may be appropriate and practicable include, but are not limited to: reducing the
sire of the project; establishing and maintaining wetland or upland vegetated buffers to protect
open waters such as streams; and replacing losses of aquatic resource functions and values by
Oct 10 03 12:37p Spangler Environmental 9195460757 p.12
creating, restoring, enhancing, or preserving similar functions and values, preferably in the same
watershed:
c. The District Engineer will require restoration, creation, enhancement, or preservation of"
other aquatic resources in order to offset the authorized impacts to the extent necessary to ensure
that the adverse effects on the aquatic environment are minimal. An important element of any
compensatory mitigation plan for projects in or near streams or other open waters is the
establishment and maintenance, to the maximum extent practicable, of vegetated buffers next to
open waters on the project site. The vegetated buffer should consist of native species. The
District Engineer will determine the appropriate width of the vegetated buffer and in which cases
it will be required. Normally, the vegetated buffer will be 25 to 50 feet wide on each side of the
stream, but the District Engineer may require wider vegetated buffers to address documented
water quality concerns. If there are open waters on the project site and the District Engineer
requires compensatory mitigation for wetland impacts to ensure that the net adverse effects on
the aquatic environment are minimal, any vegetated buffer will comprise no more than 1/3 of the
remaining compensatory mitigation acreage after the permanently filled wetlands have been
replaced on a one-to-one acreage basis. In addition, compensatory mitigation must address
adverse effects on wetland functions and values and cannot be used to offset the acreage of
wetland losses that would occur in order to meet the acreage limits of some of the NWPs (e.g.,
for NWP 39, %a acre of wetlands cannot be created to change a %i acre loss of wetlands to a %4
acre loss; however, %z acre of created wetlands can be used to reduce the impacts of'a 1/3 acre
loss of wetlands). If the prospective permittee is required to submit a compensatory mitigation
proposal with the PCN, the proposal may be either conceptual or detailed.
d. To the extent appropriate, permittees should consider mitigation banking and other
appropriate forms of compensatory mitigation. If the District Engineer determines that
compensatory mitigation is necessary to offset losses of waters of the United States and ensure
that the net adverse effects of the authorized work on the aquatic environment are minimal,
consolidated mitigation approaches, such as mitigation banks, will be the preferred method of
providing compensatory mitigation, unless the District Engineer determines that activity-specific
compensatory mitigation is more appropriate, based on which is best for the aquatic
environment. These types of mitigation are preferred because they involve larger blocks of
protected aquatic environment, are more likely to meet the mitigation goals, and are more easily
checked for compliance. If a mitigation bank or other consolidated mitigation approach is not
available in the water shed, the District Engineer will consider other appropriate forms of
compensatory mitigation to offset the losses of waters of the United States to ensure that the net
adverse effects of the authorized work on the aquatic environment are minimal.
20. Spawning Areas. Activities, including structures and work in navigable waters of the United
States or discharges of dredged or fill material, in spawning areas during spawning seasons must
be avoided to the maximum extent practicable. Activities that result in the physical destruction
(e.g., excavate, fill, or smother downstream by substantial turbidity) of an important spawning
area are not authorized.
21. Management of Water Flows. To the maximum extent practicable, the activity must be
designed to maintain preconstruction downstream (low conditions (e.g., location, capacity, and
Oct 10 03 12:38p Spangler Environmental 9195460757 p.13
flow rates). Furthermore, the activity must not permanently restrict or impede the passage of
normal or expected high flows (unless the primary purpose of the fill is to impound waters) and
the structure or discharge of dredged or fill material must withstand expected high flows. The
activity must, to the maximum extent practicable, provide for retaining excess flows from the
site, provide for maintaining surface flow rates from the site similar to preconstruction
conditions, and must not increase water flows from the project site, relocate water, or redirect
water flow beyond preconstruction conditions. In addition, the activity must, to the maximum
extent practicable, reduce adverse effects such as flooding or erosion downstream and upstream
of the project site, unless the activity is part of a larger system designed to manage water flows.
22. Adverse Effects From Impoundments. If the activity, including structures and work in
navigable waters of the United States or discharge of dredged or fill material, creates an
impoundment of water, adverse effects on the aquatic system caused by the accelerated passage
of water and/or the restriction of its flow shall be minimized to the maximum extent practicable-
23. Waterfowl Breeding Areas. Activities, including structures and work in navigable waters of
the United States or discharges of dredged or fill material, into breeding areas for migratory
waterfowl must be avoided to the maximum extent practicable.
24. Removal of Temporary Fills. Any temporary fills must be removed in their entirety and the
affected areas returned to their preexisting elevation.
25. Designated Critical Resource Waters. Critical resource waters include, NOAA-designated
marine sanctuaries, National Estuarine Research Reserves, National Wild and Scenic Rivers,
critical habitat for Federally listed threatened and endangered species, coral reefs, State natural
heritage sites, and outstanding national resource waters or other waters officially designated by a
State as having particular environmental or ecological significance and identified by the District
Engineer after notice and opportunity for public comment.
Notification is required in accordance with General Condition 13, 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 he determines that the
impacts to the critical resource waters will be no more than minimal.
26. Fills Within 100-Year Floodplains. For purposes of this general condition 100-year
floodplains will be identified through the Federal Emergency Management Agency" (FEMA)
Flood Insurance Rate Maps or FEMA-approved local floodplain maps.
27. The permitee 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.

FINAL NOTICE OF ISSUANCE AND MODIFICATION OF NATIONWIDE PERMITS
FEDERAL REGISTER
MARCH 9, 2000
Maintenance: Activities related to:
W 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 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 Clue
to changes in materials, construction techniques, or current construction codes or safety
standards which are necessary to make repair, rehabilitation, or replacement, are permitted,
provided the adverse environmental effects resulting from such repair, rehabilitation, or
replacement are minimal. Currently serviceable means useable as is or with some maintenance,
but not so degraded as to essentially require reconstruction. This nationwide permit 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.
(ii) Discharges of dredged or fill material, including excavation, into all waters of the United
States to remove accumulated sediments and debris in the vicinity of, and within, existing
structures (e.g., bridges, culverted road crossings, water intake structures, etc.) and the placement
of new or additional rip rap to protect the structure, provided the permittee notifies the District
Engineer in accordance with General Condition 13. The removal of sediment is limited to the
minimum necessary to restore the waterway in the immediate vicinity of the structure to the
approximate dimensions that existed when the structure was built, but cannot extend further than
200 feet in any direction from the structure. The placement of rip rap must be the minimum
necessary to protect the structure or to ensure the safety of the structure. All excavated materials
must be deposited and retained in an upland area unless otherwise specifically approved by the
Distri ct Engineer under separate authorization. Any bank stabilization measures not directly
associated with the structure will require a separate authorization from the District Engineer-
Oct 10 03 12:33p Spangler Environmental 9195460757 p.5
i iii, Discharges of dredged or fill material, including; excavation, into all waters of the United
-States for activities associated with the restoration of upland areas damaged by a storm, flood, or
other discrete event, including the construction, placement, or installation of upland protection
structures and minor dredging to remove obstructions in waters of the United States. (Uplands
lost as a result of a storm, flood, or other discrete event can he replaced without a Section 404
permit provided the uplands are restored to their original pre-event location. This NWP is for the
activities in waters of the United States associated with the replacement of the uplands.) The
permittee must notify the District Engineer, in accordance with General Condition 13, within 12
months of the date of the damage and the work must commence, or be under contract to
commence, within two years of the date of the damage. The permittee should provide evidence,
such as a recent topographic survey or photographs, to justify the extent of the proposed
restoration. The restoration of the damaged areas cannot exceed the contours, or ordinary high
water mark, that existed prior to the damage. The District Engineer retains the right to deterChine
the extent of the pre-existing conditions and the extent of any restoration work authorized by this
permit. Minor dredging to remove obstructions from the adjacent waterbody is limited to 50
cubic yards below the plane of the ordinary high water mark, and is limited to the amount
necessary to restore the pre-existing bottom contours of the waterbody. The dredging may not be
done primarily to obtain fill for any restoration activities. The discharge of dredged or fill
material and all related work needed to restore the upland must be part of a single and complete
project. This permit cannot be used in conjunction with NWP 18 or NWP 19 to restore damaged
upland areas. This permit does not authorize the replacement of lands lost through gradual .
erosion processes.
Maintenance dredging for the primary purpose of navigation and beach restoration are not
authorized by this permit. This permit does not authorize new stream channelization or stream
relocation projects. Any work authorized by this permit must not cause more than minimal
degradation of water quality, more than minimal changes to the flow characteristics of the
stream, or increase flooding (See General Conditions 4 and 21). (Sections 10 and 404)
Note: This NWP authorizes the minimal impact repair, rehabilitation, or replacement of any
previously authorized structure or fill that does not qualify for the Section 404(f) exemption for
maintenance.

:NATIONWIDE PERMIT #3: MAINTENANCE.
Section 10 and 404
NATIONWIDE PERMIT CONDITIONS
1. Navigation. No activity may cause more than a minimal adverse effect on navigation..
2. Proper Maintenance. Any structure or fill authorized shall be properly maintained, including
maintenance to ensure public safety. jt?
3. 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.
4. Aquatic Life Movements. No activity may substantially disrupt the movement of those
species of aquatic life indigenous to the waterbody, including those species which normally
migrate through the area, unless the activity's primary purpose is to impound water. Culverts
placed in streams must be installed to maintain low flow conditions.
5. Equipment. Heavy equipment working in wetlands must be placed on mats, or other
measures must be taken to minimize soil disturbance.
5. Regional and Case-By-Case Conditions. The activity must comply with any regional
conditions which 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 or tribe in its Section 401 water
quality certification and Coastal Zone Management Act consistency determination.
7. 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 effect 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 in the area (e.g., National Park Service, U.S. Forest
Service, Bureau of Land Management, U.S. Fish and Wildlife Service.)
8. Tribal rights. No activity or its operation may impair reserved tribal rights, including, but not
limited to, reserved water rights and treaty fishing and hunting rights.
9. Water Quality Certification. The permitter must comply with all conditions of General
Water Quality Certification No. 3290, issued by the North Carolina Division of Water Quality
(NCDWQ) on June 1, 2000.
Oct 10 03 12:34p Spangler Environmental 9195460757 p.7
10. Coastal Zone Management. The North Carolina Division of Coastal Management
(NCDCM), has waived consistency.
11. Endangered Species.
a. No activity is authorized under any NWP which is likely to 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, or which is likely to destroy or adversely
modify the critical habitat of such species. Non-Federal permittees shall notify the District
Engineer if any listed species or designated critical habitat might be affected or is in the vicinity
of the project, or is located in the designated critical habitat and shall not begin work on the
activity until notified by the District Engineer that the requirements of the Endangered Species
Act have been satisfied and that the activity is authorized. For activities that may affect
Federally-listed endangered or threatened species or designated critical habitat, the notification
must include the name(s) of the endangered or threatened species that may be affected by the
proposed work or that utilize the designated critical habitat that may be affected by the proposed
work. 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 NWP's.
b. Authorization of an activity by a NWP does not authorize the "take" of a
threatened or endangered species as defined under the Federal Endangered Species Act.
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. Fish and Wildlife Service
or the National Marine Fisheries Service, both lethal and non4ethal "takes" of protected
species are in violation of the Endangered Species Act. Information on the location of
threatened and endangered species and their critical habitat can be obtained directly
from the offices of the U.S. Fish and Wildlife Service and National Marine Fisheries
Service or their world wide web pages at http://www.fws.gov/r9endspp/endspp.html and
http://nfins.gov/prot res/esahome.html, respectively.
12. Historic Properties. No activity which may affect historic properties listed, or eligible for
listing, in the National Register of Historic Places is authorized, until the District Engineer has
complied with the provisions of 33 CFR part 325, Appendix C. The prospective permittee must
notify the District Engineer if the authorized activity may affect any historic properties listed,
determined to be eligible, or which the prospective permittee has reason to believe may be
eligible for listing on the National Register of Historic Places, and shall not begin the activity
until notified by the District Engineer that the requirements of the National Historic Preservation
Act have been satisfied and that the activity is authorized. Information on the location and
existence of historic resources can be obtained from the State Historic Preservation Office and
the National Register of Historic Places (see 33 CFR 330.4(g))_ For activities that may affect
historic properties listed in, or eligible for listing in, the National Register of Historic Places, the
notification must state which historic property may be affected by the proposed work or include
a vicinity map indicating the location of the historic property.
13. Notification:
Oct 10 03 12:35p Spangler Environmental 9195460757 p.8
a. Timing. Where required by the terms of the NWP, the prospective permittee must notify
the District Engineer with a PreConstruction Notification (PCN) as early as possible. The
District Engineer must determine if the PCN is complete within 30 days of the date of receipt
and can request the 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:
(1) Until 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) If notified by the District or Division Engineer that an individual permit is required;
or
(3) Unless 45 days have passed from the District Engineer's receipt of the complete
notification and the prospective permittee has not received written notice from the District or
Division Engineer. Subsequently, the permittee's right to proceed under the NWP may be
modified, suspended, or revoked only in accordance witli the procedure set forth in 33 CFR
330.5(d)(2); and
b. Contents of notification. The notification 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; and
(3) Brief description of the proposed project; the project's purpose; direct and indirect
adverse environmental effects the project would cause; and 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.
c. Form of Notification: The standard individual permit application form (Form ENG 4345)
may be used as the notification but must clearly indicate that it is a PCN and must include all the
information required in b.(I)-(3) of General Condition 13. A letter containing the requisite
information may also be used.
d. District Engineer's Decision: 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. The prospective permittee may, optionally, submit a proposed mitigation plan with the
PCN to expedite the process and 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 work arc minimal. If the
District Engineer determines that the activity complies with the terms and conditions of the NWP
Oct 10 03 12:35p Spangler Environmental 9195460757 p,9
and that the effects on the aquatic environment are minimal, the District Fngineer will notify the
permittee and include any conditions the District Engineer deems necessary.
Any compensatory mitigation proposal must be approved by the District Engineer prior to
commencing work. If the prospective permittee is required to submit a compensatory mitigation
proposal with the PCN, the proposal may be either conceptual or detailed. If the prospectiv:
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 plan within 45 days of receiving a complete PCN and determine whether the
conceptual or specific 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 stating that the project can proceed under the terms and conditions of the nationwide--
permit.
If the District Engineer determines that the adverse effects of the proposed work are more
than minimal, then he will notify the applicant either:
(1) 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:
(2) that the project is authorized under the NWP subject to the applicant's submission of
a mitigation proposal that would reduce the adverse effects on the aquatic environment to
the minimal level; or
(3) that the project is authorized under the NWP with specific modifications or
conditions.
Where the District Engineer determines that mitigation is required in order to ensure no
more than minimal adverse effects on the aquatic environment, the activity will be authorized
within the 45-day PCN period, including the necessary conceptual or specific mitigation or a
requirement that the applicant submit a mitigation proposal that would reduce the adverse effects
on the aquatic environment to the minimal level. When conceptual mitigation is included, or a
mitigation plan is required under item (2) above, no work in waters of the United States will
occur until the District Engineer has approved a specific mitigation plan.
e. Agency Coordination. 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 effects on the aquatic
environment to a minimal level.
For activities requiring notification to the District Engineer that result in the loss of greater
than ''/Z acre of waters of the United States, the District Engineer will, upon receipt of a
notification, provide immediately (e.g., via facsimile transmission, overnight mail, or other
expeditious manner), a copy to the appropriate offices of the Fish and Wildlife Service, State
Oct 10 03 12:36p Spangler Environmental 9195460757 p.10
natural resource or water quality agency, F.PA. State Historic Preservation Officer (SHPO), and,
if appropriate, the National Marine Fisheries Service. i 6Vitfr the exception ofNlVP 37,r These
agencies will then 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.
If so contacted by an agency, the District Engineer will wait an additional 15 calendar days
before making a decision on the notification. The District Engineer will fully consider agency
comments received within the specified time frame, but will provide no response to the resource
agency, except as provided below. The District Engineer will indicate in the administrative
record associated with each notification that the resource agencies' concerns were considered.
As required by Section 305(b)(4)(B) of the Magnuson-Stevens Fishery Conservation and
Management Act, the District Engineer will provide a response to National Marine Fisheries
Service within 30 days of receipt of any Essential Fish Habitat conservation recommendations.
Applicants are encouraged to provide the Corps multiple copies of notifications to expedite
agency notification.
f. Wetlands Delineations. 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 site. There may be some delay if the Corps does the delineation. Furthermore, the 45-
day period will not start until the wetland delineation has been completed and submitted to the
Corps, where appropriate.
g. For activities that may adversely affect Federally-listed endangered or threatened species,
the PCN must include the name(s) of those endangered or threatened species that may be
affected by the proposed work or utilize the designated critical habitat that may be affected by
the proposed work.
h. For activities that may affect historic properties listed in, or eligible for listing in, the
National Register of Historic Places, 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.
i. For activities that may adversely affect Federally-listed endangered or threatened species,
the PCN must include the name(s) of those endangered or threatened species that may be
affected by the proposed work or utilize the designated critical habitat that may be affected by
the proposed work.
j. For activities that may affect historic properties listed in, or eligible for listing in, the
National Register of Historic Places, 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.
14. Compliance Certification. Every permittee who has received a Nationwide permit
verification from the Corps will submit a signed certification regarding the completed work and
any required mitigation. The certification will be forwarded by the Corps with the authorization
letter. The certification will include:
a. A statement that the authorized work was done in accordance with the (:ores
authorization, including; any general or specific conditions;
Oct 10 03 12:36p Spangler Environmental 9195460757 p.11
b. A statement that any required mitigation was completed in accordance with the permit
conditions. and
c. The signature of the pcrmittee certifying the completion of the work and mitigation.
15. 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.
16. Water Supply Intakes. No activity, including structures and wort: in navigable waters oflhe
United States or discharges of dredged or fill material, may occur in the proximity of a public
water supply intake except where the activity is for repair of the public water supply intake
structures or adjacent bank stabilization.
17. Shellfish Beds. No activity, including structures and work in navigable waters of the United
States or discharges of dredged or fill material, may occur in areas of concentrated shellfish
populations, unless the activity is directly related to a shellfish harvesting activity authorized by
NWP 4.
18. Suitable Material. No activity, including structures and work in navigable waters of the
United States or discharges of dredged or fill material, may consist of unsuitable material (e.g.,
trash, debris, car bodies, asphalt, etc.) and material used for construction or discharged must be
free from toxic pollutants in toxic amounts (see Section 307 of the Clean Water Act).
19. Mitigation. The project must be designed and constructed to avoid and minimize adverse
effects to waters of the United States to the maximum extent practicable at the project site (i.e.,
on site). Mitigation will be required when necessary to ensure that the adverse effects to the
aquatic environment are minimal. The District Engineer will consider the factors discussed
below when determining the acceptability of appropriate and practicable mitigation necessary to
offset adverse effects on the aquatic environment that are more than minimal
a. Compensatory mitigation at a minimum I:1 ratio will be required for all wetland impacts
requiring a PCN. Consistent with National Policy, the District Engineer will establish a
preference for restoration of wetlands to meet the minimum compensatory mitigation ratio, with
preservation used only in exceptional circumstances.
b. To be practicable, the mitigation must be available and capable of being done considering
costs, existing technology, and logistics in light of the overall project purposes. Examples of
mitigation that may be appropriate and practicable include, but are not limited to: reducing the
size of the project; establishing and maintaining wetland or upland vegetated buffers to protect
open waters such as streams; and replacing losses ofaquatic resource functions and values by
Oct 10 03 12:37p Spangler Environmental 9195460757 p.12
creating, restoring, enhancing, or preserving similar functions and values, preferably in the satne
watershed:
c. The District Engineer will require restoration, creation, enhancement, or preservation of"
other aquatic resources in order to offset the authorized impacts to the extent necessary to ensure
that the adverse effects on the aquatic environment are minimal. An important element of any
compensatory mitigation plan for projects in or near streams or other open waters is the
establishment and maintenance, to the maximum extent practicable, of vegetated buffers next to
open waters on the project site. The vegetated buffer should consist of native species. The
District Engineer will determine the appropriate width of the vegetated buffer and in which cases
it will be required. Normally, the vegetated buffer will be 25 to 50 feet wide on each side of the
stream, but the District Engineer may require wider vegetated buffers to address documented
water quality concerns. If there are open waters on the project site and the District Engineer
requires compensatory mitigation for wetland impacts to ensure that the net adverse effects on
the aquatic environment are minimal, any vegetated buffer will comprise no more than I/3 of the
remaining compensatory mitigation acreage after the permanently filled wetlands have been
replaced on a one-to-one acreage basis. In addition, compensatory mitigation must address
adverse effects on wetland functions and values and cannot be used to offset the acreage of
wetland losses that would occur in order to meet the acreage limits of some of the NWPs (e.g.,
for NWP 39, K acre of wetlands cannot be created to change a %z acre loss of wetlands to a %4
acre loss; however, %z acre of created wetlands can be used to reduce the impacts ot'a 1/3 acre
loss of wetlands). If the prospective permittee is required to submit a compensatory mitigation
proposal with the PCN, the proposal may be either conceptual or detailed.
d. To the extent appropriate, permittees should consider mitigation banking and other
appropriate forms of compensatory mitigation. If the District Engineer determines that
compensatory mitigation is necessary to offset losses of waters of the United States and ensure
that the net adverse effects of the authorized work on the aquatic environment are minimal,
consolidated mitigation approaches, such as mitigation banks, Nvill be the preferred method of
providing compensatory mitigation, unless the District Engineer determines that activity-specific
compensatory mitigation is more appropriate, based on which is best for the aquatic
environment. These types of mitigation are preferred because they involve larger blocks of
protected aquatic environment, are more likely to meet the mitigation goals, and are more easily
checked for compliance. If a mitigation bank or other consolidated mitigation approach is not
available in the water shed, the District Engineer will consider other appropriate forms of
compensatory mitigation to offset the losses of waters of the United States to ensure that the net
adverse effects of the authorized work on. the aquatic environment are minimal.
20. Spawning Areas. Activities, including structures and work in navigable waters of the United
States or discharges of dredged or fill material, in spawning areas during spawning seasons must
be avoided to the maximum extent practicable. Activities that result in the physical destruction
(e.g., excavate, fill, or smother downstream by substantial turbidity) of an important spawning
area are not authorized.
21. Management of Water Flows. To the maximum extent practicable, the activity must be
designed to maintain preconstruction downstream flow conditions (e.g., location, capacity, and
Oct 10 03 12:38p Spangler Environmental 8195460757 p.13
flow rates). Furthermore, the activity must not permanently restrict or impede the passage of
normal or expected high flows (unless the primary purpose of the fill is to impound waters) and
the structure or discharge of dredged or fill material must withstand expected high flows. The
activity must, to the maximum extent practicable, provide for retaining excess flows from the
site, provide for maintaining surface flow rates from the site similar to preconstruction
conditions, and must not increase water flows from the project site, relocate water, or redirect
water flow beyond preconstruction conditions. In addition, the activity must, to the maximum
extent practicable, reduce adverse effects such as flooding or erosion downstream and upstream
of the project site, unless the activity is part of a larger system designed to manage water flows.
22. Adverse Effects From Impoundments. If the activity, including structures and work in
navigable waters of the United States or discharge of dredged or fill material, creates an
impoundment of water, adverse effects on the aquatic system caused by the accelerated passage
of water and/or the restriction of its flow shall be minimized to the maximum extent practicable-
23. Waterfowl Breeding Areas. Activities, including structures and work in navigable waters of
the United States or discharges of dredged or fill material, into breeding areas for migratory
waterfowl must be avoided to the maximum extent practicable.
24. Removal of Temporary Fills. Any temporary fills must be removed in their entirety and the
affected areas returned to their preexisting elevation.
25. Designated Critical Resource Waters. Critical resource waters include, NOAA-designated
marine sanctuaries, National Estuarine Research Reserves, National Wild and Scenic Rivers,
critical habitat for Federally listed threatened and endangered species, coral reefs, State natural
heritage sites, and outstanding national resource waters or other waters officially designated by a
State as having particular environmental or ecological significance and identified by the District
Engineer after notice and opportunity for public comment.
Notification is required in accordance with General Condition 13, 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 he determines that the
impacts to the critical resource waters will be no more than minimal.
26. Fills Within 100-Year Floodplains. For purposes of this general condition 100-year
floodplains will be identified through the Federal Emergency Management Agency" (FEMA)
Flood Insurance Rate Maps or FEMA-approved local floodplain maps.
27. The permitee 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.

• Eagle Ridge - Phase 8B
Garner, North Carolina
Storm Water
Calculation Report
General Description
The Eagle Ridge - Phase 8B development is located off Old Stage Road Garner, NC.
The project is a proposed single family subdivision. The existing topography of this site
splits drainage flow into three directions. The existing draw on the north side of the
property drains approximately half the site. The existing draw to the east drains
approximately a quarter of the site and the remaining quarter of the site drains to the
existing lake on the west side of the site. The property is open field with only a few trees
and includes the exiting lake. The proposed storm sewer will collect the stormwater and
convey it to the existing lake on the west side of the site. Additionally, small areas will
• bypass the proposed storm sewer and will exit the site through the existing draws.
Calculation Methodology
• For each individual storm drainage inlet, a drainage area was measured as well as
assigning impervious surface percentage. From this impervious percentage, a rational c
factor was calculated. This data was used later for pipe sizing.
• The pipes were sized using StormCAD v 4. 1.1 software by Haestad Methods. This
program accepts the input data from each inlet, as well as physical characteristics of the
storm system to be designed, and calculates flow rates and pipe sizes throughout the
system. For rainfall data, an IDF curve describing the Raleigh-Durham region was used.
The final results of this program as well as calculated pipe sizes and hydraulic grade lines
may be found in the appropriate section of this report. In traffic bearing areas, the
minimum pipe size was 15" RCP.
• Reinforced concrete pipe is specified for all storm drain piping, and corrugated HDPE
piping is specified for all storm service piping.
• Stormwater will discharge to the existing lake on site. This lake is part of the Neuse
River watershed and therefore has a 50' Neuse River Riparian buffer associated with it.
• The various inlet types are shown on the detail sheets, within the plan set. Flared end
sections are used at all culvert inlet and discharge points. Velocity dissipators are
provided at discharge points to prevent erosion and scour in these areas. The dissipators
have been sized using the NYDOT method.
----- - - --- -- - -• Level spreaders and bypass structures are-used.at-all -outlet points. All 1"/hour storm
events will flow through the level spreader. Any flow above 1"/hour will bypass the
• level spreader and flow directly into the lake.
• The storm water network has been designed to pass the 10-year storm event.
• Erosion control calculations include calculations for all of the specified temporary
sediment traps and basins.
