APPROVAL of 401 Water Quality Certification and AUTHORIZATION CERTIFICATE per the Neuse River
Buffer ProtectionRuIes (15A NCAC 2B .0233) with ADDmONAL CONDmONS

Dear Mr. Peterson,

You have our approval, in accordance with the additional conditions listed below, to impact approximately 2,250
square feet of the protected riparian buffers for the purpose of constructirig the proposed raw water intake structures, as
descnOed within your application dated November 9,2001. This letter shall act as your Authorization Certificate for
impacts to the protected riparian buffers associated per 15A NCAC 2B .0233(8). After reviewing your application, we
have decided that the proposed water impacts associated with the raw 1i"ater intal:e structures are covered by General
Water Quality Certification Number 3288 (GC3288). This Certification allows you to use Nationwide PertnitNo. 12
when issued by the US Army Corps of Engineers (USACE).). In addi1ion, you should get 01' otherwise comply with any
other required federaL state or local permits before you go ahead with your pr~ including (but not limited to) Sediment
and Eiosion ControL
Impacts associated with the "sewer main" crossing of tributaIy stream are also covered under GC 3288. Written
concurrence is not required from the Division of Water Quality (DWQ) for the use of GC3288 if all the conditions of
GC3288 are met. However, please be aWare that the constroc1ion conirlIor of the proposed sewer line can not impact the
riparian buffer other than "exempt" activities identified ~ 15A NCAC 2B .0233(6). These "exempt" activities include
perpendicular crossings tbatdistmb equal to or less than 40 linear feet of ripariaa buffer with a maintenance corridor equal
to or less than 10 feet in width Parnllel impacts to the protected buff'e:5 caused by the constmction corridor will require
written authorization from the DWQ prior to construction and possibly buffer ~tion and are not approved under this
letter. ~. :c' -:',;~:~'-,--:);',~:-:.h:(j;l~'t"~. .

011675 (Edward Ristaino, Mecklenburg Co.) - Property in WS-IV. ~
Shoreline stabilization project and rebuilding of dock for single family
residential using masonry and rock. As far as the WSWP Rules as
concerned it is a water dependent activity and therefore allowed.
Disturbed vegetation will need to be replaced. Catawba Rules also apply
and here it's an allowable use but, no avoidance and minimization was
given or practical alternative. Concerned that the "masonry and rock"
will not allow for percolation.

Catawba Rules also apply, minimal avoidance and minimization given, but
no practical alternative. An allowed use.

far as the WSWP Rules as concerned it is a water dependent activity and

the Catawba Rules also apply, and no practical alternatives language
described in the packet I was given. ~~ allowed use. There was a very
minimal is tic summary of how the owner would try to keep the damage to a
minimum. I think he should go further, and I suggest'making him replant
as many trees as he removes.

011670 (Panther Creek - Raleigh LP, Wake Co.) - What a monster of a
project!!! This project is in WS-IV-PA near Jordan Lake. Neuse Rules
don't apply. The Wake County.will need to review project for BUA, V';r,
stormwater, buffer requirements. My guess is that it's a high density r~~
project, which will require stODrrNater EMPs and 100' buffers. They're
looking to have another 5 stream/buffer crossings for access around the
site. 7 crossings were allowed under a previous permit. WSWP Rules do
not allow these crossings since it's a p=ivate project. Of course we
can't deny access to a site, but they already have 7 and I don't think
they need all 5 of the ones they're asking for now. Strict adherence to
the WSWPRules -would- say deny the permit. But if we have to allow it,
the crossings must minimize BOA, divert runoff away from surface waters,
use BMPs, and show no practical alternative. There was no sununary
included on how there was no practical alternative summary given for the
5 access crossings they're requesting DU~. Plus they don't want to pay
for mitigation for 4 of the 5 points since they already paid for them in
the previous permitting process. It's not our fault their permit ran
out before they built them. It's a ne-... permit and I think they should
have to pay again - but WSWP Rules don't have anything to say about
that.

Pre-Construction Notification (PCN) Application Form

For Section 404 and/or Section 10 Nationwide, Regional and General Permits, Section 401
General Water Quality Certifications, and Riparian Buffer and Watershed Buffer Rules

This form is to be used for projects qualifying for any of the U.S. Army Corps of Engineers' (USACE)
Nationwide, Regional or General Permits as required by Section 404 of the Clean Water Act and/or
Section 10 of the Rivers and Harbors Act, and for the North Carolina Division of Water Quality's
(DWQ) associated General 401 Water Quality Certifications. This form is also to be used for any
project requiring approval under any Riparian Buffer Rules implemented by the N.C. Division of Water
Quality. This form should not be used if you are requesting an Individual 404 Permit or Individual 401
Water Quality Certification. The USACE Individual Permit application form is available online at
http://www.saw.usace.army.millwetIandsIPermapp.htm.

The USACE is the lead regulatory agency. To review the requirements for the use of Nationwide,
Regional or General permits, and to determine which permit applies to your project, please go to the
USACE website at http://www.saw.usace.army.millwetlands/regtour.htm. or contact one of the field
offices listed at the end of this application. The website also lists the responsible project manager for
each county in North Carolina and provides additional information regarding the identification and
regulation of wetlands and waters of the U.S.

The DWQ issues a corresponding Certification (General or Individual), and cannot tell the applicant
which 401 Certification will apply until the 404 Permit type has been determined by the USACE.
Applicants are encouraged to visit DWQ's 401/Wetlands Unit website at
http://h2o.enr.state.nc.us/ncwetlands to read about current requirements for the 401 Water Quality
Certification Program and to determine whether or not Riparian Buffer Rules are applicable. The
applicant is also advised to read the full text of the General Certification (GC) matching the specific 404
Permit requested. In some cases, written approval for some General Certifications is not required,
provided that the applicant adheres to all conditions of the GC. Applicants lacking access to the internet
should contact DWQ's Central Office in Raleigh at [phone].

Trout Waters Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is also required for projects occurring in any of North Carolina's twenty-five
counties that contain trout waters. In such cases, the applicant should contact the appropriate NCWRC
regional coordinator (listed by county on the last page of this application).

Page 1 of 12

ro4 ~

CAMA Coordination - If the project occurs in any of North Carolina's twenty coastal counties (listed on
the last page of this application) the applicant should also contact the North Carolina Division of Coastal
Management (DCM) at [phone]. DCM will determine whether or not the project involves a
designated Area of Environmental Concern, in which case DCM will act as the lead permitting agency.
In such cases, DCM will require a Coastal Area Management Act (CAMA) Permit and will coordinate
the 404/401 Permits.

USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable US ACE Regulatory Field Office (addresses are listed at the end of this
application). Upon receipt of an application, the USACE will determine if the application is complete as
soon as possible, not to exceed 30 days. This PCN form is designed for the convenience of the applicant
to address information needs for all US ACE Nationwide, Regional or General permits, as well as
information required for State authorizations, certifications, and coordination. Fully providing the
information requested on this form will result in a complete application for any of the USACE
Nationwide, Regional or General permits. To review the minimum amount of information that must be
provided for a complete PCN for each USACE Nationwide permit, see Condition 13,65 Fed.Reg. 12893
(March 9, 2000), available at http://www.saw.usace.army.mil/wetlands/nwpfinalFedReg.pdf.
Processing times vary by permit and begin once the application has been determined to be complete.
Please contact the appropriate regulatory field office for specific answers to permit processing periods.

401 Water Quality Certification or Buffer Rules - All information is required unless otherwise stated
as optional. Incomplete applications will be returned. Submit seven collated copies of all USACE
Permit materials to the Division of Water Quality, 401lWetlands Unit, 1650 Mail Service Center,
Raleigh, NC, 27699-1650. If written approval is required or specifically requested for a 401
Certification, then a non-refundable application fee is required. In brief, if project impacts include less
than one acre of cumulative wetland/water impacts and less than 150 feet cumulative impacts to
streams, then a fee of $200 is required. If either of these thresholds is exceeded, then a fee of $475 is
required. A check made out to the North Carolina Division of Water Quality, with the specific name of
the project or applicant identified, should be stapled to the front of the application package. For more
information, see the DWQ website at http://h2o.ehnr.state.nc.us/ncwetlands/fees.html. The fee must be
attached with the application unless the applicant is a federal agency in which case the check may be
issued from a separate office. In such cases, the project must be identifiable on the U.S. Treasury check
so that it can be credited to the appropriate project. If written approval is sought solely for Buffer Rules,
the application fee does not apply, and the applicant should clearly state (in a cover letter) that only
Buffer Rule approval is sought in writing. Wetlands or waters of the U.S. may not be impacted prior to
issuance or waiver of a Section 401 Water Quality Certification. Upon receipt of a complete application
for a 401 Certification, the Division of Water Quality has 60 days to prepare a written response to the
applicant. This may include a 401 Certification, an on-hold letter pending receipt of additional
requested information, or denial.

local stormwater requirement, etc.):

Size of watershed draining to pond:

Expected pond surface area:

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.
Crossing the tributary of the Eno River is unavoidable due to economic constraints. The sewer
line route chosen is the shortest most direct route from the water treatment plant to the
Hillsborough collection system. In addition, construction of a new intake structure or
modification of the existing structure is required to prevent disruption in service and protect
intake equipment due to flood events. This project will raise vital electrical equipment above the
100 year flood elevation. Stream impacts during construction will be minimized to the fullest
extent possible with sediment and erosion control devices. The stream bed and the stream bed
and bank shall be stabilized and restored as necessary to original grades following construction.

Page 7 of 12

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 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:/OOo.em.state.nc.us/ncwetlands/strmgide.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.
N/A

Page 8 of 12

2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401lWetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http://h20.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): N/ A
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A

IX. Environmental Documentation (DWQ Only)

Does the project involve an expenditure of public funds or the use of public (federal/state/local)
land?

Yes (g]

No D

If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEP A1SEP A)?
Note: If you are not sure whether a NEP A1SEP A document is required, call the SEP A
coordinator at [phone] to review current thresholds for environmental documentation.
Yes D No (g]

If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEP A or SEP A final approval letter.
Yes D No D

X. Proposed Impacts on Riparian and Watershed Buffers (DWQ Only)

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
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify Neuse )?
Yes (g] No D If you answered "yes", provide the following information:

Page 9 of 12

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 Multiplier Required
(square feet) Mitigation
1 1350 3
2 900 1.5
Total 2250

*

Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.

If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or .0260.

XI. Stormwater (DWQ Only)

Describe impervious acreage (both 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.
The intake site is predominantly pervious with grass and low scrub cover. Following
construction, the site will be restored to a predominantly pervious condition. Therefore, this
proj ect' s contribution to additional runoff is insignificant.

XII. Sewage Disposal (DWQ Only)

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 Hillsborough WWTF has a capacity of 3 MGD. This project will contribute an additional
0.1 MGD to an average daily flow of 1.2 MGD.

XIII. Violations (DWQ Only)

Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes D No [gJ

Is this an after-the-fact permit application?
Yes D No [gJ

Page 10 of 12

XIV. 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
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
The project is being funded through the NC SRF program. Plans and specifications are
approved. The Town of Hillsborough is ready to advertise the project and proceed to
construction pending USCOE and NC DWQ approval. Also, the project includes upgrades to the
disinfection system which makes the Town's water compatible with the water from surrounding
systems. Without the upgrades, the Town will be unable to receive or deliver water to
surrounding systems. The disinfection system improvements must be completed by early 2002.

Memo To:

U.S. Fish & Wildlife Service -- Mr. Garland Pardue
N.C. State Historic Preservation Office -- Ms. Renee Gledhill-Early
U.S. Army Corps of Engineers -- Dr. G. Wayne Wright

Project:

NEPA Categorical Exclusion (CE) for Upgrade of Town of Hillsborough Raw
Water Pump Station and Treatment Plant, Orange County NC.
DEH-PWS Project No,

Applicant:

Mr. Kenneth P. Keel, P.E., Hillsborough Town Engineer
P.O. Box 429, Hillsborough NC 27278 [phone]

CE Contact: Mr. Gerald Pottern, Robert J. Goldstein & Associates, Inc.
8480 Garvey Drive, Raleigh NC 27616-3175 [phone]
G [e-mail]

The Town of Hillsborough (applicant) has requested federal funding from the Drinking
Water State Revolving Fund (DWSRF) to upgrade its existing 3.0 mgd raw water pump station
and water treatment plant without capacity expansion. We have requested Categorical
Exclusion (CE) from substantive environmental review under NC-SEPA minimum criteria (15A
NCAC 1 C.0504) for this project. Before granting this request, the NC-DENR Public Water
Supply Section (PWS) requires that your agency comment on the advisability of issuing aCE.

The water intake is on the' north bank of theEno River at Ben Johnson Dam, 1.8 miles
west of downtown Hillsborough. The water treatment plant is on Dimmocks Mill Road (SR
1144) 0.4 mile east of the intake, as illustrated on the attached map. The proposed
improvements include the following items, with an estimated total cost of 3.3 million dollars.

1) Construct a new raw water pump station adjacent to the existing RWI
2) Construct a new 1.0 million gallon potable water clearwell
3) Upgrade yard piping to eliminate water storage short-Circuiting
4) Install a new high service finished water pumping station and backwash pumps
5) Install a stand-by generator for emergency operation during power failures
6) Rebuild and replace water treatment filters
7) Replace electrically operated filter valves
8) Replace filter loss-of-head instrumentation
9) Replace filter operation consoles
10) Replace influent flash mixer
11) Rehabilitate aging Concrete
12) Upgrade electrical systems
13) Construct a 0.5 mile sewerline to convey sludge lagoon supernatant and septic
wastewater to the Town WWTP

The proposed intake pump station and treatment plant construction areas are on
previously disturbed Town land containing structures, lawn, herb/sapling scrub, or
unvegetated land. The only undisturbed land to be cleared is a 2,360 foot long, 30-foot wide
construction corridor for the proposed 8-inch diameter sewerline. This corridor contains
upland pine/hardwood and alluvial hardwood forest.

The new raw water pump station and WTP improvements will be constructed above
the 100-year floodplain elevation as mapped by FEMA. The eastern half of the backwash
effluent sewerline will be in the floodplain, with manholes sealed and vented above the 100-
year flood elevation. FEMA 100-year floodplain elevations in the project area are
approximately 524 feet above Ben Johnson Dam, 519 feet near the WTP, and 516 feet near
the proposed sewerline connection point.

RJG&A surveyed the proposed construction areas for jurisdictional wetlands, waters,
and protected species habitats during 1999. The project includes minor construction on the
Eno River bank and one small tributary crossing (for the sewerline), but no wetland impacts.
No protected species was encountered in the construction areas, but several state-protected
species occur in the adjacent Eno River. As there will be no capacity expansion, this project
is unlikely to cause significant direct or indirect changes in land use.

Please provide your written comments to me at the address on this letterhead, and we
will forward copies to Vincent Tomaino at PWS. If you require additional information about
the project or environmental setting, please call or email me.
