VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Impact #1 (Aerial Sewer Crossing):
2,152 square feet of "allowable" riparian buffer impact (1 205square feet Zone 1 and 947
square feet Zone 2),
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

7. Isolated Waters
Do any isolated waters exist on the property? ? Yes ® No
Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
No isolated waters are present on the subject property.
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): N/A
Current land use in the vicinity of the pond: N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. Permanent impacts to
jurisdictional streams and wetlands have been avoided completely. The Neuse River Riparian
buffer impacts associated with the aerial sewer crossing are necessary to connect to the existing
Town of Apex Sewer line, which is located on the other side of the UT to Middle Creek. In an
effort to avoid any stream and/or wetland impacts, the applicant moved the sewer corridor south
of the large wetland tract and proposed an aerial sewer line to cross the stream. The applicant
opted not to install the sewer line via jack and bore and/or directional drilling/boring
methodologies because this would require a significant amount of room in order to prepare the
location as well as set up and stage the appropriate equipment necessary. The location of
existing buildings parking lots precludes the use of jack and bore and directional
drilling/boring methods for installing the proposed sewer lines This approach of sewer
installation would also create more Riparian Buffer impact overall. And finally, the elevation of
the existing manhole across the UT to Middle Creek would preclude the use of directional
drilling methodologies (i.e. the existing manhole location is at a higher elevation than the
proposed manhole).
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.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, 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 NCEEP 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
hLtp://h2o.enr.state.nc.us/ncwetlands/stnngide.html.
1. 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.
No permanent impacts to streams and/or wetlands are proposed therefore stream and/or
wetland mitigation is not being _proposed. Additionally, the Neuse River Riparian buffer
impacts are "allowable" per the table of uses 115 A NCAC 2B 0233 (01 therefore buffer
mitigation is not being proposed.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at htt2://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): 0
Amount of buffer mitigation requested (square feet): 0
Amount of Riparian wetland mitigation requested (acres): 0
Amount of Non-riparian wetland mitigation requested (acres): 0
Amount of Coastal wetland mitigation requested (acres): 0
IX. Environmental Documentation (required by DWQ)
1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ? No
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No ?
3. If yes, has the document review been finalized by the State Clearinghouse? If so, please
attach a copy of the NEPA or SEPA final approval letter. Yes ? No ?
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.
1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify. Neuse )? Yes ® No ?
2. If "yes", 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.
Impact #1 - Aerial Sewer Crassin¢ - "Allawahle"

3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260. The impacts to the Neuse River Riparian
Buffers are "allowable" per 15A NCAC 2B .0233 (6) and therefore, buffer mitigation is not
required.
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss stormwater
controls proposed in order to protect surface waters and wetlands downstream from the property. If
percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed
impervious level. This project proposes "allowable" impacts to the protected Neuse River Riparian
Buffers and therefore a stormwater management plan is not required. The applicant has provided
2 level spreaders (see attached Stormwater Plan sheet, Level Spreader Worksheets, Required
Item Checklists and O&M Agreements) to comply with the diffuse flow provisions within the
Neuse River Riparian Buffer Rules.
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
The proposed project is to install a sewer line which will tie into existing adjacent lines.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application? Yes ? No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ? No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description:
We have reviewed the "DRAFT Internal Policy, Cumulative impacts and the 401 Water Quality
Certification and Isolated Wetland Procrams" document pre arp ed by the NC Division of Water
Quality on April 10, 2004, version 2.1. The draft states that small development projects are
unlikely to cause cumulative impacts. This utility project does not meet any of the three criteria
of private projects that can clearly result in cumulative impacts The proposed project is within
an already developed landscape. We anticipate that you will advise us if a qualitative or
quantitative impact analysis is required.
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may

FILTER STRIP, RESTORED RIPARIAN BUFFER, AND LEVEL
SPREADER. OPERATION & MAINTENANCE AGREEMENT
I will keep a maintenance record on this BM[P. This maintenance record will be kept in a log in a
known, set location. Any deficient BUT elements noted in the inspection will be corrected;
repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety
or the public, and the pollutant removal efficiency of the BAP.

A filter strip, is a section of land capable of sustaining sheet flow and is either forested or
vegetated with turf grasses or other plants. Restored riparian buffers are natural or constructed
lowsmaintenance ecosystems adjacdni to surface water bodies with trees, grasses, shrubs; and
herbaceous plants. Level spreaders do not remove pollutants ,by.thern elves, but they are crucial
in assuring the effectiveness of certain DAps and in protecting the function of riparian. buffers.
A level spreader consists of a concrete linear structure constructed at virtually zero percent
grade: One of the main purposes of a level spreader is to disperse concentrated stormwater flows
over a wide enough area to prevent erosion of the BMP or filter strip where it outlets:
Important inspection and maintenance procednres:
Immediately after the filter strip is established, any newly planted vegetation will
be watered twice weekly if needed until the plants become established (conunonly
six weeks). The watering should take place on designated days according to the
odd/even watering schedule cited in the Town of Apex Code of Ordinances.
Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation:
• Stable groundcover will be maintained in the drainage area to reduce the sediment
load to the vegetation-
• Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3. to 5 inches and
may be allowed to grow as tall as 12 inches -depending on aesthetic requirements.
• Once a year, the soil will be aerated and lime will be added if necessary.
• Remove any weeds or shrubs growing on level spreader or in swale.
• Inspect the level lip for settling, erosion, or-concentrated flow..
After the filter strip is established, I will inspect it and the level spreader (if applicable) guarterly
and within 24, hours after every.storm.event heater than 1.0 inches. Records of inspection and
maintenance will be kept in a known, set location and will be available upon request.
