Perry Hill Mitigation Site Buffer Baseline Monitoring Report
DMS ID No. 100093 Page 1 May 2021
1.0 Mitigation Project Summary
The Perry Hill Mitigation Site (Site) is a riparian restoration project located in Orange County
approximately three miles northwest of Hillsborough, NC (Figure 1). Figure 2 depicts the service area of
the Site which includes the Falls Lake watershed in the Neuse river basin. Wildlands recorded a 26.88-
acre conservation easement that encompasses portions of Perry Branch, three unnamed tributaries
(UT1, UT2, and UT3) and two ephemeral channels (EC1 and EC3) as illustrated in Figure 3. Before
construction, most of the Site served as an active cattle pasture, with some forested riparian areas also
utilized by cattle. The project is expected to generate 874,590.412 riparian buffer credits.
The Site is within Hydrologic Unit Code (HUC) 03020201030020 and North Carolina Department of
Water Resources (DWR) Sub-basin 03-04-01. Three unnamed tributaries (UT1, UT2, and UT3) drain to
Perry Branch, which drains to Corporation Lake water supply reservoir on the Eno River, and then Falls
Lake. Falls Lake is classified as water supply waters (WS-IV) and nutrient sensitive waters (NSW).
1.1 Project Goals
The major goals of the riparian restoration project are to provide ecological and water quality
enhancements to the Neuse River Watershed within the Falls Lake Water Supply Watershed by creating
a functional riparian corridor and restoring the riparian area. The project supports specific goals
identified in the 2010 Neuse River Basin Restoration Priorities Plan (RBRP) for the Neuse River Targeted
Local Watershed (TLW). This document highlights the importance of riparian buffers for stream
restoration projects. Forested riparian areas immobilize and retain nutrients and suspended sediment.
The RBRP also supports the Falls Lake watershed plan. Falls Lake is a receiving water supply water body
downstream of the Site and is classified as WS-IV and NSW. Specific enhancements to water quality and
ecological processes are outlined below:
• Exclude cattle from project streams and adjacent riparian areas. – Fencing has been installed
around project areas adjacent to cattle pastures.
• Restore and enhance native floodplain vegetation. – Planted native tree species in riparian zone
where tree growth was insufficient.
• Permanently protect the project Site from harmful uses. – Established a conservation easement
on the Site.
1.2 Pre-construction Site Conditions
The riparian restoration and enhancement project included 16.77 acres of cattle pasture (restoration)
and 7.94 acres of riparian forest (enhancement) along Perry Branch, unnamed tributaries, and
ephemeral channels that drain into the Neuse River Basin. Prior to construction, the primary
degradation to the streams and associated riparian zones were the result of cattle. The difference
between the total conservation easement area and the restoration area is associated with areas not
included for buffer credit such as stream channels, crossing, etc. Aerial photographs illustrate
agricultural activities at the Site over the past 80 plus years.
The Site contains one perennial stream Perry Branch; three intermittent streams UT1; UT2; and UT3;
and two ephemeral channels EC1 and EC3. The buffer project attributes are listed in Table 1, located in
Appendix 6.1.
On February 26, 2019, DWR conducted on-site determinations to review features and land use within
the project boundary. The resulting DWR site viability letter and map confirming the Site as suitable for
riparian buffer mitigation is located in Appendix 6.2. Perry Branch and the three unnamed tributaries are
appropriate for buffer mitigation as related to the rules set forth in the Consolidated Buffer Mitigation

Perry Hill Mitigation Site Buffer Baseline Monitoring Report
DMS ID No. 100093 Page 2 May 2021
Rules (15A NCAC 02B 0.0295 (o)(7)). In addition to buffer restoration on subject streams, per the
Consolidated Buffer Mitigation Rules (15A NCAC 02B 0.0295 (o)), alternative mitigation included buffer
restoration on ephemeral channels and enhancement via livestock exclusion.
2.0 Determination of Credits
The project is expected to generate 874,590.412 riparian buffer credits, through buffer restoration and
buffer enhancement via cattle exclusion, per the Consolidated Buffer Mitigation Rules (15A NCAC 02B
0.0295 (o)). There is also potential to convert some buffer credits to nutrient offset credits, dependent
on the need. Mitigation credits are presented in Table 2 and illustrated in Figure 3 (Appendix 6.1).
Calculations are based upon the as-built survey included in Appendix 6.3.
3.0 Baseline Summary
Wildlands restored high quality riparian areas along Perry Branch, three unnamed tributaries, and two
ephemeral channels on the Site. The buffer mitigation took place in conjunction with Perry Hill Stream
Mitigation. The project design minimized impacts to existing riparian areas at the Site. Figure 3
illustrates the design for the Site. Detailed descriptions of the restoration activity follow in Sections 3.1
through 3.3. Overview site photographs are included in Appendix 6.4.
3.1 Parcel Preparation
Prior to stream construction, the Site was cattle pasture, with livestock having access to all streams
causing streambank erosion. Onsite streams and riparian buffers at the Site were restored and/or
enhanced. The approved permits are included in Appendix 6.5.
Wildlands treated invasive plants at the Site to reduce native competition post construction.
Additionally, fescue was treated at the Site to mitigate the adverse effects (i.e., direct competition and
allelopathic impacts) on planted vegetation.
Soil amendments were incorporated on-site prior to planting per the mitigation plan. The contractor
ripped soils at the Site to a depth of 12” on a 3’ spacing along haul roads and 6’ spacing for other
planted areas to reduce soil compaction prior to planting activities.
3.2 Riparian Area Restoration Activities
The revegetation plan for the riparian restoration area included planting bare root trees and live stakes
(Table 1) as well as permanent seeding. In total, 13,883 woody stems were planted across the Site.
These revegetation efforts were coupled with the select treatment of invasive species to control their
population. The species composition planted was selected based on the desired community type,
occurrence of species in riparian areas adjacent to the Site, and best professional judgement.
Wildlands planted trees at a density sufficient to meet the performance standards outlined in the Rule
15A NCAC 02B .0295 of 260 trees per acre at the end of five years. An appropriate seed mix was applied
as necessary to provide temporary ground cover for soil stabilization and reduction of sediment loss
during rain events in disturbed areas. This was followed by an appropriate permanent seed mixture.Tree
planting was completed in April 2021.
Vegetation management and herbicide applications were implemented prior to planting activities to
treat non-native, invasive species. Additionally, Wildlands implemented ring spray herbicide treatments
at the base of planted bare roots to reduce competition (treat fescue). This practice is designed to
encourage tree growth (and reduce tree mortality) and fescue will be re-treated if necessary in MY2.

3.3 Riparian Area Enhancement Activities
Fencing excludes cattle throughout the entire project as allowed by 15A NCAC 02B .0295(o). Fencing
was installed along the exterior boundary, encompassing both this project and the Perry Hill II Mitigation
Bank Parcel (Figure 3). The enhancement area is protected in perpetuity via a conservation easement.
4.0 Annual Monitoring and Performance Criteria
The performance criteria for the Site follows approved performance criteria presented in the guidance
documents outlined in Request for Proposal (RFP) 16-007576 and the Consolidated Buffer Rule (15A
NCAC 02B .0295). Annual monitoring and semi-annual site visits will be conducted to assess the
condition of the finished project. The riparian restoration project has been assigned specific
performance criteria components for vegetation that will be evaluated throughout the five-year post-
construction monitoring. An outline of the performance criteria and monitoring components follows.
Monitoring components are included in Table 3 and vegetation plot locations are depicted in Figure 4
(Appendix 6.1).
4.1 Vegetation
Performance standards for the Site will be based on the health and survival of a minimum density of 260
trees per acre after five years of monitoring, with a minimum of four native hardwood tree or shrub
species composition and no one species comprising more than 50 percent of stems. Vigor, species
composition, height, and density will be used as indicators of overall health. Desirable volunteer species
may be included to meet the success criteria upon DWR approval. The extent of non-native, invasive
species coverage will also be monitored and treated as necessary throughout the required five-year
monitoring period. Wildlands will monitor impacts of fescue on the targeted plant communities at the
Site during the monitoring period. In the event fescue is preventing the establishment of the targeted
plant community, Wildlands will prescribe a specific remedial plan of action.
Fourteen fixed 100 square meter vegetation monitoring quadrants were installed across the Site to
measure the survival of the planted stems (Figure 4) with a mean of 581 stems per acre (Table 4,
Appendix 6.6). Vegetation monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation
(2008). All planted stems were marked with flagging tape and a reference photograph was taken from
the southwestern corner of each vegetation plot during vegetation assessments. Each year, trees will be
re-marked and plot photos will be taken along with overview photographs of the Site. Appendix 6.6
includes the baseline (MY0) vegetation plot planted and total stem counts, as well as plot photographs.
4.2 Overview Photographs
Photographs will be taken within the project area once a year to visually document stability for five
years following construction. Baseline overview photographs are included in Appendix 6.4.
4.3 Visual Assessments
Visual assessments should support the performance standards for each metric as described above.
Visual assessments will be performed within the Site on a semi-annual basis during the five-year
monitoring period. Problem areas with vegetative health will be noted (e.g. low stem density, vegetation
mortality, invasive species, or encroachment). Areas of concern will be mapped and photographed
accompanied by a written description in the annual report. Problem areas will be re-evaluated during
each subsequent visual assessment.
4.4 Annual Reporting Performance Criteria
Using the Division of Mitigation Services (DMS) Riparian Buffer and Nutrient Offset Buffer Baseline and
Annual Monitoring Report Template version 2.0 (2017), monitoring reports will be prepared in the fall of

Perry Hill Mitigation Site Buffer Baseline Monitoring Report
DMS ID No. 100093 Page 5 May 2021
each monitoring year and submitted to DMS. The monitoring period will extend five years beyond
completion of construction or until performance criteria have been met.
4.5 Maintenance and Contingency Plans
The conservation easement has been properly and accurately marked by adding witness posts with
easement placards along the easement boundary and at every corner. Adaptive management will be
performed during the monitoring years to address minor issues as necessary. If during annual
monitoring it is determined the project’s ability to achieve performance standards are jeopardized,
Wildlands will notify and work with the DMS/DWR to develop contingency plans and remedial actions.
Any actions implemented will be designed to achieve the success criteria specified previously and will
include a work schedule and updated monitoring criteria (if applicable).

The Division of Water Resources (DWR) received a Request from Wildlands Engineering, Inc.
(Wildlands) for a Stream Buffer Applicability Determination for a potential mitigation site at the
location described above. A Landowner Authorization Form was provided by Wildlands for the
subject site. On February 26, 2019, DWR staff, along with staff from Wildlands and Division of
Mitigation Services conducted a site visit.
DWR determined that two (2) features on the site, Perry Branch and one Unnamed Tributary to
Perry Branch (UT1) are both streams and are subject to the Neuse River Riparian Buffer Rules
and are both located on the most recently published NRCS Soil Survey of Guilford County, North
Carolina. There are two (2) other Unnamed Tributaries to Perry Branch, UT2 and UT3, that were
determined to be at least intermittent but not subject to the Neuse River Riparian Buffer Rules.
There may be other streams or features located on the properties and on the included maps
that may be subject to the buffer rules or may be considered jurisdictional according to the
US Army Corps of Engineers and subject to the Clean Water Act.
This on -site determination shall expire five (5) years from the date of this letter. Landowners
or affected parties that dispute a determination made by the DWR may request a determination
by the Director. An appeal request must be made within sixty (60) calendar days of the date of
this letter to the Director in writing.

Re: Site Viability for Buffer Mitigation & Nutrient Offset — Perry Hill Site
Located near 2623 Frank Perry Rd, Hillsborough
Neuse 03020201
Dear Mr. Hutton,
On February 25, 2019, Katie Merritt, with the Division of Water Resources (DWR), received a
request from Wildlands Engineering, Inc. (Wildlands) for an onsite mitigation determination
near the above -referenced site (Site). The Site is located within the Upper Falls Lake
Watershed of the Neuse River Basin in the 8-digit Hydrologic Unit Code. The Site is being
proposed as part of a full -delivery nutrient offset, stream and riparian buffer mitigation
project for the Division of Mitigation Services (RFP #16-007576). Members of the
Interagency Review Team (IRT) and Division of Mitigation Services were also present
onsite. At your request, on February 26, 2019, Ms. Merritt performed an onsite assessment of
riparian land uses adjacent to streams onsite, which are shown on the attached map labeled
"Concept Map".
Ms. Merritt's evaluation of the features onsite and their associated mitigation determination for the
riparian areas are provided in the table below. This evaluation was made from Top of Bank (TOB)
and. landward 200' from each feature for buffer mitigation pursuant to 15A NCAC 02B .0295
(effective November 1, 2015) and for nutrient offset credits pursuant to 15A NCAC 02B .0240.

2 NC Division of Water Resources - Methadolow and Calcularians_for determining !Nutrient Reductions associated with Riparian Buffer
Establishment
3'Fhe area of preservation credit within a buffer mitigation site shall comprise of no more than 25 percent (25%) of the total area of buffer
mitigation per 15A NCAC 0295 (o)(5) and 15A NCAC 0295 (o)(4). Site cannot be a Preservation Only site to comply with this rule.
'The area described as an Enhancement Site was assessed and determined to comply with all 15A NCAC 02B .0295(o)(5). Cattle
exclusion fencing is required to be installed around the mitigation area to get buffer credit under this part of the rule.
Me area of the mitigation site on ephemeral channels shall comprise no more than 25 percent (25%) of the total area of buffer
mitigation per 15A NCAC 02B .0295 (o)(7).
The maps attached to this letter were prepared by Wildlands and were initialed by Ms. Merritt on
April 15, 2019 and April 16, 2019. This letter should be provided in all stream and wetland,
buffer and/or nutrient offset mitigation plans for this Site.
This letter does not constitute an approval of this site to generate mitigation credits. Pursuant to 15A
NCAC 02B .0295, a mitigation proposal and a mitigation plan shall be submitted to DWR for written
approval prior to conducting any mitigation activities in riparian areas and/or surface waters for
buffer mitigation credit. Pursuant to 15A NCAC 02B .0240, a proposal regarding a proposed nutrient
load -reducing measure for nutrient offset credit shall be submitted to DWR for approval prior to any
mitigation activities in riparian areas and/or surface waters.
All vegetative plantings, performance criteria and other mitigation requirements for riparian
restoration, enhancement and preservation must follow the requirements in 15A NCAC 02B .0295 to
be eligible for buffer and/or nutrient offset mitigation credits. For any areas depicted as not being
viable for nutrient offset credit above, one could propose a different measure, along with supporting
calculations and sufficient detail to support estimates of load reduction, for review by the DWR to
determine viability for nutrient offset in accordance with 15A NCAC 02B .0240.

Hey Chris, 
Based on Mr. Mckee’s letter and other site factors I observed during my site visit on February 26, 2019, I will support 
that cattle had access to the areas circled in the picture below.  Therefore, based on this assessment, would you like to 
provide a revised map for me to use for the Site Viability letter?  Thus, showing the Preservation area (green) as cattle 
exclusion for Enhancement?  If so, let me know.

Hey John, 
Below is a picture showing two forested areas hatched in black.  Based on my onsite observations of these areas and my 
review of the historical photos I was able to dig up, I am not certain that these areas qualify under 15A NCAC 02B .0295 
(o)(6) to receive Enhancement buffer credit at a 2:1 ratio.  These areas did have cattle access during the time of our site 
visit.  However, when looking at both historical aerials of these areas prior to the buffer protection rule as well as the 
presence of relic pasture fencing in and around the areas, it would appear the cattle were excluded from having access 
at some point and possibly prior to the effective date of the rule (1997).  It isn’t until approximately 2008 that cows are 
observed in the fields adjacent to EC3 and Reach 1 of Perry Branch shown highlighted in Yellow below.  Unless Wildlands 
has anything more they can provide me to assist in this assessment to confirm w/o a doubt there were cows present in 
the forested areas prior to the effective buffer rule date, I’m going to issue the viability letter based on my Best 
Professional Judgement and show these areas as viable for Preservation buffer credit under 15A NCAC 02B .0295 (o)(4) 
which would yield a ratio of 5:1.  I’d like to issue this letter by the 15th if at all possible, so please send me anything you 
have prior to then.  If Wildlands agrees with the assessment of Preservation, then no information is required and the 
letter will be issued.  

Thank you, 
Katie

sedimentation and erosion control designs shall comply with the requirements set forth in
15A NCAC 04B .0124, Design Standards in Sensitive Watersheds.
6. Sediment and erosion control measures shall not be placed in wetlands or waters except
within the footprint of temporary or permanent impacts authorized under this Certification.
Exceptions to this condition require application to and written approval from DWR. [15A
NCAC 02H .0501 and .0502]
7. Erosion control matting that incorporates plastic mesh and/or plastic twine shall not be
used along streambanks or within wetlands. Exceptions to this condition require
application to and written approval from DWR. [15A NCAC 02B .0201]
8. An NPDES Construction Stormwater Permit (NCG010000) is required for construction
projects that disturb one (1) or more acres of land. The NCG010000 Permit allows
stormwater to be discharged during land disturbing construction activities as stipulated in
the conditions of the permit. If the project is covered by this permit, full compliance with
permit conditions including the erosion & sedimentation control plan, inspections and
maintenance, self -monitoring, record keeping and reporting requirements is required. [15A
NCAC 02H .0506(b)(5) and (c)(5)]
The North Carolina Department of Transportation (NCDOT) shall be required to be in full
compliance with the conditions related to construction activities within the most recent
version of their individual NPDES (NCS000250) stormwater permit. [15A NCAC 02H
.0506(b)(5) and (c)(5)]
9. All work in or adjacent to streams shall be conducted so that the flowing stream does not
come in contact with the disturbed area. Approved best management practices from the
most current version of the NC Sediment and Erosion Control Manual, or the NC DOT
Construction and Maintenance Activities Manual, such as sandbags, rock berms,
cofferdams, and other diversion structures shall be used to minimize excavation in flowing
water. Exceptions to this condition require application to and written approval from DWR.
[15A NCAC 02H .0506(b)(3) and (c)(3)]
10. If activities must occur during periods of high biological activity (e.g. sea turtle nesting, fish
spawning, or bird nesting), then biological monitoring may be required at the request of
other state or federal agencies and coordinated with these activities. [15A NCAC 02H
.0506(b)(2) and 15A NCAC 04B .0125]

GC4134
Work within a designated trout watershed of North Carolina (as identified by the
Wilmington District of the US Army Corps of Engineers), or identified state or federal
endangered or threatened species habitat, shall be coordinated with the appropriate WRC,
USFWS, NMFS, and/or DMF personnel.
11. Culverts shall be designed and installed in such a manner that the original stream profiles
are not altered and allow for aquatic life movement during low flows. The dimension,
pattern, and profile of the stream above and below a pipe or culvert shall not be modified
by widening the stream channel or by reducing the depth of the stream in connection with
the construction activity. The width, height, and gradient of a proposed culvert shall be such
as to pass the average historical low flow and spring flow without adversely altering flow
velocity. [15A NCAC 02H .0506(b)(2) and (c)(2)]
Placement of culverts and other structures in streams shall be below the elevation of the
streambed by one foot for all culverts with a diameter greater than 48 inches, and 20% of
the culvert diameter for culverts having a diameter less than or equal to 48 inches, to allow
low flow passage of water and aquatic life.
If multiple pipes or barrels are required, they shall be designed to the mimic the existing
stream cross section as closely as possible including pipes or barrels at flood plain elevation
and/or sills where appropriate. Widening the stream channel shall be avoided.
When topographic constraints indicate culvert slopes of greater than 5%, culvert burial is
not required, provided that all alternative options for flattening the slope have been
investigated and aquatic life movement/connectivity has been provided when possible (e.g.
rock ladders, cross vanes, etc.). Notification, including supporting documentation to include
a location map of the culvert, culvert profile drawings, and slope calculations, shall be
provided to DWR 60 calendar days prior to the installation of the culvert.
When bedrock is present in culvert locations, culvert burial is not required provided that
there is sufficient documentation of the presence of bedrock. Notification, including
supporting documentation such as a location map of the culvert, geotechnical reports,
photographs, etc. shall be provided to DWR a minimum of 60 calendar days prior to the
installation of the culvert. If bedrock is discovered during construction, then DWR shall be
notified by phone or email within 24 hours of discovery.
If other site -specific topographic constraints preclude the ability to bury the culverts as
described above and/or it can be demonstrated that burying the culvert would result in
destabilization of the channel, then exceptions to this condition require application to and
written approval from DWR.
Page 6 of 10

GC4134
Installation of culverts in wetlands shall ensure continuity of water movement and be
designed to adequately accommodate high water or flood conditions. When roadways,
causeways, or other fill projects are constructed across FEMA-designated floodways or
wetlands, openings such as culverts or bridges shall be provided to maintain the natural
hydrology of the system as well as prevent constriction of the floodway that may result in
destabilization of streams or wetlands.
The establishment of native woody vegetation and other soft stream bank stabilization
techniques shall be used where practicable instead of rip -rap or other bank hardening
methods.
12. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be
directed across the bridge and pre-treated through site -appropriate means to the maximum
extent practicable (e.g. grassed swales, pre -formed scour holes, vegetated buffers, etc.)
before entering the stream. Exceptions to this condition require application to and written
approval from DWR. [15A NCAC 02H .0506(b)(5)]
13. Application of fertilizer to establish planted/seeded vegetation within disturbed riparian
areas and/or wetlands shall be conducted at agronomic rates and shall comply with all
other Federal, State and Local regulations. Fertilizer application shall be accomplished in a
manner that minimizes the risk of contact between the fertilizer and surface waters. [15A
NCAC 02B .0200 and 15A NCAC 02B .0231]
14. If concrete is used during construction, then all necessary measures shall be taken to
prevent direct contact between uncured or curing concrete and waters of the state. Water
that inadvertently contacts uncured concrete shall not be discharged to waters of the state.
[15A NCAC 02B .0200]
15. All proposed and approved temporary fill and culverts shall be removed and the impacted
area shall be returned to natural conditions within 60 calendar days after the temporary
impact is no longer necessary. The impacted areas shall be restored to original grade,
including each stream's original cross sectional dimensions, planform pattern, and
longitudinal bed profile. For projects that receive written approval, no temporary impacts
are allowed beyond those included in the application and authorization. All temporarily
impacted sites shall be restored -and stabilized with native vegetation. [15A NCAC 02H
.0506(b)(2) and (c)(2)]
16. All proposed and approved temporary pipes/culverts/rip-rap pads etc. in streams shall be
installed as outlined in the most recent edition of the North Carolina Sediment and Erosion
Control Planning and Design Manual or the North Carolina Surface Mining Manual or the
North Carolina Department of Transportation Best Management Practices for Construction
and Maintenance Activities so as not to restrict stream flow or cause dis-equilibrium during
use of this Certification. [15A NCAC 02H .0506(b)(2) and (c)(2)]
Page 7 of 10

GC4134
17. Any rip -rap required for proper culvert placement, stream stabilization, or restoration of
temporarily disturbed areas shall be restricted to the area directly impacted by the
approved construction activity. All rip -rap shall be placed such that the original stream
elevation and streambank contours are restored and maintained. Placement of rip -rap or
other approved materials shall not result in de -stabilization of the stream bed or banks
upstream or downstream of the area or in a manner that precludes aquatic life passage.
[15A NCAC 02H .0506(b)(2)]
18. Any rip -rap used for stream or shoreline stabilization shall be of a size and density to
prevent movement by wave, current action, or stream flows and shall consist of clean rock
or masonry material free of debris or toxic pollutants. Rip -rap shall not be installed in the
streambed except in specific areas required for velocity control and to ensure structural
integrity of bank stabilization measures. [15A NCAC 02H .0506(b)(2)]
19. Applications for rip -rap groins proposed in accordance with 15A NCAC 07H .1401 (NC
Division of Coastal Management General Permit for construction of Wooden and Rip -rap
Groins in Estuarine and Public Trust Waters) shall meet all the specific conditions for design
and construction specified in 15A NCAC 07H .1405.
20. All mechanized equipment operated near surface waters shall be inspected and maintained
regularly to prevent contamination of surface waters from fuels, lubricants, hydraulic fluids,
or other toxic materials. Construction shall be staged in order to minimize the exposure of
equipment to surface waters to the maximum extent practicable. Fueling, lubrication and
general equipment maintenance shall be performed in a manner to prevent, to the
maximum extent practicable, contamination of surface waters by fuels and oils. [15A NCAC
02H .0506(b)(3) and (c)(3) and 15A NCAC 02B .0211 (12)]
21. Heavy equipment working in wetlands shall be placed on mats or other measures shall be
taken to minimize soil disturbance. [15A NCAC 02H .0506 (b)(3) and (c)(3)]
22. In accordance with 143-215.85(b), the applicant shall report any petroleum spill of 25
gallons or more; any spill regardless of amount that causes a sheen on surface waters; any
petroleum spill regardless of amount occurring within 100 feet of surface waters; and any
petroleum spill Tess than 25 gallons that cannot be cleaned up within 24 hours.
23. If an environmental document is required under the State Environmental Policy Act (SEPA),
then this General Certification is not valid until a Finding of No Significant Impact (FONSI) or
Record of Decision (ROD) is issued by the State Clearinghouse. If an environmental
document is required under the National Environmental Policy Act (NEPA), then this
General Certification is not valid until a Categorical Exclusion, the Final Environmental
Assessment, or Final Environmental Impact Statement is published by the lead agency. [15A
NCAC 01C .0107(a)]

Charlotte, NC 28203

RE: Project Name: Perry Hill Mitigation Site
Acres Approved: 13.73
Project ID: ORANG-2021-002
County: Orange
City: Hillsborough
Address: Frank Perry Road
River Basin: Neuse
Stream Classification: HQW
Submitted By: Wildlands Engineering, Inc., ATTN: Geoff Smith, PE
Date Received by LQS: November 23, 2020
Plan Type: Revised

Dear Mr. Wilkerson:

The subject erosion and sedimentation control plan has been approved. The enclosed Certificate
of Approval must be posted at the job site. This plan approval shall expire three (3) years following
the date of approval, if no land-disturbing activity has been undertaken, as is required by Title 15A
NCAC 4B .0129.

As of April 1, 2019, all new construction activities are required to complete and submit an
electronic Notice of Intent (eNOI) form requesting a Certificate of Coverage (COC) under the
NCG010000 Construction General Permit. After the form is reviewed and found to be complete,
you will receive a link with payment instructions for the $100 annual permit fee. After the fee is
received, you will receive the COC via email. You MUST obtain the COC prior to commencement
of any land disturbing activity. The eNOI form may be accessed at deq.nc.gov/NCG01. Please
direct questions about the eNOI form to Annette Lucas at [e-mail] or Paul
Clark at [e-mail]. If the owner/operator of this project changes in the future, the
new responsible party is required to apply for his/her own COC.

Title 15A NCAC 4B .0118(a) and the NCG01 permit require that the following documentation be
kept on file at the job site:

1. The approved E&SC plan as well as any approved deviation.
2. The NCG01 permit and the COC, once it is received.
3. Records of inspections made during the previous 12 months.

Also, this letter gives the notice required by G.S. 113A-61.1(a) of our right of periodic inspection
to insure compliance with the approved plan.

Title 15A NCAC 4B .0118(a) requires that a copy of the approved erosion control plan be on file
at the job site. Also, this letter gives the notice required by G.S. 113A-61.1(a) of our right of
periodic inspection to insure compliance with the approved plan.

North Carolina's Sedimentation Pollution Control Act is performance-oriented, requiring
protection of existing natural resources and adjoining properties. If, following the commencement
of this project, it is determined that the erosion and sedimentation control plan is inadequate to meet
the requirements of the Sedimentation Pollution Control Act of 1973 (North Carolina General
Statute 113A-51 through 66), this office may require revisions to the plan and implementation of
the revisions to ensure compliance with the Act.

Acceptance and approval of this plan is conditioned upon your compliance with Federal and State
water quality laws, regulations, and rules. In addition, local city or county ordinances or rules may
also apply to this land-disturbing activity. This approval does not supersede any other permit or
approval.

Please note that this approval is based in part on the accuracy of the information provided in the
Financial Responsibility Form, which you provided. You are requested to file an amended form if
there is any change in the information included on the form. This permit allows for a land-
disturbance, as called for on the application plan, not to exceed the approved acres.  Exceeding the
acreage will be a violation of this permit and would require a revised plan and additional
application fee. In addition, it would be helpful if you notify this office of the proposed starting
date for this project. Please notify us if you plan to have a preconstruction conference.
