("Bank Parcel") to provide Neuse Riparian Buffer mitigation credit ("Riparian Buffer Credits")
and Neuse Nutrient Strategy nutrient load reduction credit ("Nutrient Offset Credits") is made
and entered into by and among Restoration Systems, LLC acting as the Bank Sponsor
("Sponsor"), and the North Carolina Department of Environmental Quality — Division of Water
Resources ("DWR"). This Instrument is in accordance with 15A NCAC 02B .0240 and the
Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295, which became effective on
November 1, 2015 (Attachment D and E).
The purpose of the Bank is:
A. To improve water quality, reduce nutrient loads, enhance flood attenuation and restore
wildlife habitat along a tributary to Falling Creek through the restoration of riparian buffers
and adjacent riparian areas.
B. To capture, treat and attenuate stormwater runoff by establishing wide woody riparian
vegetation along agricultural ditches and a stream.
C. To provide mitigation and sell any resulting Riparian Buffer Credits and/or Nutrient Offset
Credits to third parties in the Neuse River Basin, excluding the Falls Watershed, for
development (both existing and proposed) requiring such mitigation.
It. LOCATION AND GEOGRAPHIC SERVICE AREA
A. The Geographic Service Area ("GSA") is the designated area wherein a Bank can
reasonably be expected to sell Riparian Buffer Credits and/or Nutrient Offset Credits for
impacts due to development activities.
B. The Bank Parcel is located within the Neuse River Basin in the State of North Carolina,
United States Geological Survey ("USGS") 8 -digit Hydrologic Unit Code ("HUC")
03020201.
C. The project is comprised of one parcel of land in Wayne County, NC. The property has
been actively used for both poultry farming and cattle pasture and is accessed from Weaver
Road, in Grantham, NC. The project is located at 35.303888 N and 78.129087 W.
D. An unnamed tributary to Falling Creek is the receiving body of water for stormwater runoff
from this parcel. Falling Creek is classified by DWR as Nutrient Sensitive Waters (NSW).
E. Sale or transfer of Riparian Buffer Credits shall be limited to the 8 -digit HUC 03020201,
with the exception of the Falls Lake Watershed, unless otherwise authorized by the DWR
or delegated local government in accordance with 15A NCAC 02B .0295.

15A NCAC 0211 .0240 NUTRIENT OFFSET PAYMENTS
(a) The purpose of this Rule is to establish procedures for the optional payment of nutrient offset fees to the NC
Ecosystem Enhancement Program, subsequently referred to as the Program, or to other public or private parties where the
Program or such parties implement projects for nutrient offset purposes and accept payments for those purposes, and
where either of the following applies:
(1) The following rules of this Section allow offsite options or nutrient offset payments toward fulfillment
or maintenance of nutrient reduction requirements:
(A) .0234 and .0235 of the Neuse nutrient strategy,
(B) .0258 of the Tar -Pamlico nutrient strategy, and
(C) applicable rules of the Jordan nutrient strategy, which is described in Rule .0262; and
(2) Other rules adopted by the Commission allow this option toward fulfillment of nutrient load reduction
requirements.
(b) Offset fees paid pursuant to this Rule shall be used to achieve nutrient load reductions subject to the following
geographic restrictions:
(1) Load reductions shall be located within the same 8 -digit cataloguing unit, as designated by the US
Geological Survey, as the loading activity that is being offset;
(2) The Division shall track impacts by 10 -digit watershed, as designated by the US Geological Survey
and providers shall locate projects proportional to the location of impacts to the extent that the projects
would meet the least cost alternative criterion per S.L. 2007-438. The location of load reduction
projects shall be reviewed during the approval process described in Paragraph (c) of this Rule;
(3) Impacts that occur in the watershed of Falls Lake in the upper Neuse River Basin may be offset only
by load reductions in the same watershed; Impacts in the Neuse 01 8 -digit cataloguing unit below the
Falls watershed, as designated by the US Geological Survey, may be offset only by load reductions in
that same lower watershed;
(4) Restrictions established in the Jordan nutrient strategy, which is described in Rule 15A NCAC 02B
.0262; and
(5) Any further restrictions established by the Commission through rulemaking.
(c) The Program and other parties shall obtain Division approval of proposed nutrient offset projects prior to
construction. Other parties shall sell credits in compliance with approved credit release schedules and with the
requirements of this Rule. Project approval shall be based on the following standards:
(1) Load reductions eligible for credit shall not include reductions used to satisfy other requirements under
the same nutrient strategy;
(2) The Program and other parties shall agree to provide adequate financial assurance to protect and
maintain load reductions for the stated duration, including for maintenance, repair and renovation of
the proposed measure;
(3) The Program and other parties shall agree that once credits are established for a measure and until they
are exhausted, they shall provide a credit/debit ledger to the Division at regular intervals;
(4) The Program and other parties shall agree that the party responsible for a measure shall allow the
Division access to it throughout its lifetime for compliance inspection purposes;
(5) The Program or other party seeking approval shall obtain a site review from Division staff prior to
Division approval to verify site conditions suitable to achieve the proposed load reductions through the
proposed measure; and
(6) The Program shall submit a proposal, and other parties shall submit a proposal or a draft banking
instrument, addressing the following items regarding a proposed load -reducing measure:
(A) Identify the location and site boundaries of the proposed measure, the geographic area to be
served by credits in compliance with the requirements of Paragraph (b) of this Rule, existing
conditions in the contributing drainage area and location of the measure, and the nature of the
proposed measure with sufficient detail to support estimates of load reduction required in this
Paragraph;
(B) Provide calculations of the annual magnitudes of load reductions and identify final credit
values incorporating any delivery factors or other adjustments required under rules identified
in Paragraph (a) of this Rule;
(C) Define the duration of load reductions, and provide a conservation easement or similar legal
mechanism to be recorded with the County Register of Deeds and that is sufficient to ensure
protection and maintenance of load reductions for the stated duration;

(D) Identify the property owner and parties responsible for obtaining all permits and other
authorizations needed to establish the proposed measure, for constructing and ensuring initial
performance of the proposed measure, for reporting on and successfully completing the
measure, for holding and enforcing the conservation easement, and for ensuring protection
and maintenance of functions for its stated duration;
(E) Provide a plan for implementing the proposed measure, including a timeline, a commitment
to provide an as -built plan and report upon establishment of the measure, elements to be
included in the as -built plan and report, a commitment to provide a bond or other financial
assurance sufficient to cover all aspects of establishment and initial performance prior to the
release of any credits, and criteria for successful completion; and
(F) Provide a monitoring and maintenance plan designed to achieve successful completion, that
commits to annual reporting to the Division until success is achieved, that recognizes the
Division's authority to require extension or re-initiation of monitoring depending on progress
toward success, and that commits to a final report upon completion. The final report shall
reaffirm the party that shall hold and enforce the conservation easement or other legal
instrument.
(d) The Program shall establish and revise nutrient offset rates as set out in Rule .0274 of this Section. Offset payments
accepted by the Program shall be placed into the Riparian Buffer Restoration Fund administered by the Department
pursuant to G.S. 143-214.21
(e) Persons who seek to pay nutrient offset fees under rules of this Section shall do so in compliance with such rules, the
requirements of Paragraph (b) of this Rule, and the following:
(1) A non-governmental entity shall purchase nutrient offset credit from a party other than the Program if
such credit is available in compliance with the criteria of this Rule at the time credit is sought, and
shall otherwise demonstrate to the permitting authority that such credit is not available before seeking
to make payment to the Program;
(2) Offset payments made to the Program shall be contingent upon acceptance of the payment by the
Program. The financial, temporal and technical ability of the Program to satisfy the mitigation request
will be considered to determine whether the Program will accept or deny the request;
(3) Where persons seek to offset more than one nutrient type, they shall make payment to address each
type;
(4) The offset payment shall be an amount sufficient to fund 30 years of nutrient reduction.
(5) Persons who seek offsets to meet new development stormwater permitting requirements shall provide
proof of offset credit purchase to the permitting authority prior to approval of the development plan;
and
(6) A wastewater discharger that elects to purchase offset credits for the purpose of fulfilling or
maintaining nutrient reduction requirements shall submit proof of offset credit acquisition or a letter of
commitment from the Program or third party provider with its request for permit modification.
Issuance of a permit that applies credits to nutrient limits shall be contingent on receipt of proof of
offset credit acquisition. A discharger may propose to make incremental payments for additional
nutrient allocations, contingent upon receiving a letter of commitment from the Program or third party
provider to provide the offset credit needed for permit issuance. In that event the Division may issue
or modify that permit accordingly, and shall condition any flow increase associated with that
incremental purchase on payment in full for the additional allocation. Offset responsibility for nutrient
increases covered under this Paragraph shall be transferred to the Program or third party provider
when it has received the entire payment.
(f) Credits associated with load reducing activities funded under this Rule shall be awarded exclusively to the person,
municipality, discharger, or group of dischargers who paid the offset fee.

existing stormwater conveyances is not feasible, then they shall include a justification and shall
100%
provide a delineation of the watershed draining to the stormwater outfall and the percentage of the
33%
total drainage by area treated by the riparian buffer with the mitigation plan specified in Paragraph
(n) or (o) of this Rule for Authority approval. During mitigation plan review and approval, the
Authority may reduce credit proportionally.
(4)
Sewer easement within the buffer. If the proposed mitigation site contains a sewer easement in
Zone 1, that portion of the sewer easement within Zone 1 shall not be suitable for buffer
mitigation credit. If the proposed mitigation site contains a sewer easement in Zone 2, the portion
of the sewer easement in Zone 2 may be suitable for buffer
mitigation credit if -
(A) the applicant or mitigation provider restores or enhances the forested buffer in Zone 1
adjacent to the sewer easement;
(B) the sewer easement is required to be maintained in a condition that meets the vegetative
requirements of the collection system permit; and
(C) diffuse flow is provided across the entire buffer width.

(2) The applicant or mitigation provider shall submit a restoration or enhancement mitigation plan to
the Authority for written approval. The plan shall demonstrate compliance with the requirements
of this Paragraph and Paragraphs (1) and (m) of this Rule and shall also contain the following:
(A) A map of the proposed restoration or enhancement site;
(B) A vegetation plan that shall detail the activities proposed to ensure a final performance
standard of 260 stems per acre at the completion of monitoring. The final performance
standard shall include a minimum of four native hardwood tree species or four native
hardwood tree and native shrub species, where no one species is greater than 50 percent
of stems. Native hardwood and native shrub volunteer species may be included to meet
the final performance standard of 260 stems per acre. The Authority may approve
alternative vegetation plans upon consideration of factors, including site wetness and
plant availability, to meet the requirements of this Part;
(C) A grading plan (if applicable). The site shall be graded in a manner to ensure diffuse
flow through the entire riparian buffer;
(D) A schedule for implementation, including a fertilization and herbicide plan if applicable;
and
(E) A monitoring plan to document whether the site is expected to meet the final performance
standards as defined in Part (n)(2)(B) of this Rule and other anticipated benefits to the
adjacent water. The plan shall include a proposed schedule and method for monitoring
the vegetative status of the restoration or enhancement site for five years, including the
health and average stem densities of native hardwood tree or tree and shrub species that
are to be counted toward the final performance standard.
(3) Within one year after Authority approval of the mitigation plan, the applicant or mitigation
provider shall present documentation to the Authority that the riparian buffer has been restored or
enhanced unless the applicant or mitigation provider requests, and the Authority agrees in writing
prior to that date, to a longer time period.
(4) The applicant or mitigation provider shall submit written annual reports, unless an alternative
schedule has been approved by the Authority during the mitigation plan approval, for a period of
five years after completion of the activities identified in Part (n)(2)(B) of this Rule at the
restoration site or enhancement site showing:
(A) compliance with the monitoring plan approved pursuant to Part (n)(2)(E) of this Rule;
and
(B) that diffuse flow through the riparian buffer has been maintained.
If the Authority determines that the native hardwood tree or tree and shrub species at the site are not
expected to meet the final performance standards listed in Part (n)(2)(B) of this Rule, then the Authority
may require that the applicant or mitigation provider replace trees or trees and shrubs as needed during that
five-year period. If the Authority determines that diffuse flow through the buffer is not being maintained,
then the Authority may require that the applicant or mitigation provider restore diffuse flow. If the
Authority determines that the final performance standards listed in Part (n)(2)(B) of this Rule have not been
achieved at the end of the five-year monitoring period, the Authority may require additional years of
monitoring. The Authority shall make determinations referenced in this Subparagraph on a site specific
basis based on the annual reports, any supplemental information submitted by the applicant or mitigation
provider, or a site evaluation by the Authority.
(o) ALTERNATIVE BUFFER MITIGATION OPTIONS. Alternative buffer mitigation options are detailed in this
Paragraph. Any proposal for alternative buffer mitigation shall be provided in writing to the Division, shall meet the
content and procedural requirements for approval by the Division, shall meet the requirements set out in Paragraphs
(1) and (m) of this Rule and the requirements set out in the named Subparagraph of this Paragraph addressing that
applicable alternative buffer mitigation option:

mitigation site to meet success criteria identified in the applicable Subparagraph of this
Paragraph; and
(D) Documentation that the proposed alternative buffer mitigation site met the success
criteria identified in the applicable Subparagraph of this Paragraph.
These alternative buffer mitigation sites shall receive credit in accordance with the criteria set
forth in Paragraph (m) and Subparagraph (n)(1) of this Rule.
(2) Coastal Headwater Stream Mitigation. Wooded buffers planted along Outer Coastal Plain
headwater stream mitigation sites may also be approved as riparian buffer mitigation credit if the
site meets all applicable requirements of Paragraph (n) of this Rule. In addition, all success
criteria specified in the approval of the stream mitigation site by the Division shall be met. The
area of the buffer shall be measured perpendicular to the length of the valley being restored. The
area within the proposed buffer mitigation site shall not also be used as wetland mitigation.
(3) Buffer Restoration and Enhancement on Non -Subject Streams. Restoration or enhancement of
buffers may be conducted on intermittent or perennial streams that are not subject to the applicable
Rule .0233, .0243, .0250, .0259, .0267, or .0607 of this Subchapter. These streams shall be
confirmed as intermittent or perennial streams by Division staff certified per G.S. 143-214.25A
using the Division publication, "Methodology for Identification of Intermittent and Perennial
Streams and Their Origins (v.4.11, 2010)" available at no cost at
http://portal.ncdenr.org/web/wq/swp/ws/401/waterresources/streamdeterminations. The proposal
shall meet all applicable requirements of Paragraph (n) of this Rule.
(4) Preservation of Buffer on Non -Subject Streams. Preservation of buffers on intermittent or
perennial streams that are not subject to the applicable Rule .0233, .0243, .0250, .0259, .0267, or
.0607 of this Subchapter may be proposed in order to permanently protect the buffer from cutting,
clearing, filling, grading, and similar activities that would affect the functioning of the buffer.
These streams shall be confirmed as intermittent or perennial streams by Division staff certified
per G.S. 143-214.25A using the Division publication, "Methodology for Identification of
Intermittent and Perennial Streams and Their Origins (v4.11, 2010)." The preservation site shall
meet the requirements of Subparagraph (n)(1) of this Rule and the requirements set forth in 15A
NCAC 02R .0403(c)(7), (8), and (11). The area of preservation credit within a buffer mitigation
site shall comprise of no more than 25 percent of the total area of buffer mitigation.
(5) Preservation of Buffers on Subject Streams. Buffer preservation may be proposed on streams that
are subject to the applicable Rule .0233, .0243, .0250, .0259, .0267, or .0607 of this Subchapter in
order to permanently protect the buffer from cutting, clearing, filling, grading, and similar
activities that would affect the functioning of the buffer beyond the protection afforded by the
existing buffer rules on sites that meet the definition of a preservation site. The preservation site
shall meet the requirements of Subparagraph (n)(1) and the requirements set forth in 15A NCAC
02R .0403(c)(7), (8), and (11). The area of preservation credit within a buffer mitigation site shall
comprise of no more than 25 percent of the total area of buffer mitigation.
(6) Enhancement of grazing areas adjacent to streams. Buffer credit at a 2:1 ratio shall be available
for an applicant or mitigation provider who proposes permanent exclusion of grazing livestock
that otherwise degrade the stream and riparian zone through trampling, grazing, or waste
deposition by fencing the livestock out of the stream and its adjacent buffer. The applicant or
mitigation provider shall provide an enhancement plan as set forth in Paragraph (n) of this Rule.
The applicant or mitigation provider shall demonstrate that grazing was the predominant land use
since the effective date of the applicable buffer rule.
(7) Mitigation on ephemeral channels. For purposes of riparian buffer mitigation as described in this
Part, an "ephemeral channel" is defined as a natural channel exhibiting discernible banks within a
topographic crenulation (V-shaped contour lines) indicative of natural drainage on the 1:24,000
scale (7.5 minute) quadrangle topographic map prepared by the U.S. Geologic Survey, or as seen
on digital elevation models with contours developed from the most recent available LiDAR data,
available at no cost at http://www.ncfloodmaps.com/lidar.com. Ephemeral channels only flow for
a short period of time after precipitation in the drainage area and do not have periods of base flow

sustained by groundwater discharge. The applicant or mitigation provider shall provide a
delineation of the watershed draining to the ephemeral channel. The entire area proposed for
mitigation shall be within the contributing drainage area to the ephemeral channel. The ephemeral
channel shall be directly connected to an intermittent or perennial stream and contiguous with the
rest of the mitigation site protected under a perpetual conservation easement. The area of the
mitigation site on ephemeral channels shall comprise no more than 25 percent of the total area of
buffer mitigation. The proposal shall meet all applicable requirements of Paragraph (n) of this
Rule for restoration or enhancement. The proposal shall meet all applicable requirements of
Subparagraph (0)(4) or (0)(5) of this Rule for preservation.
(8) Restoration and Enhancement on Ditches. For purposes of riparian buffer mitigation as described
in this Part, a "ditch" is defined as a man-made channel other than a modified natural stream that
was constructed for drainage purposes. To be used for mitigation, a ditch shall meet all of the
following criteria:
(A) be directly connected with and draining towards an intermittent or perennial stream;
(B) be contiguous with the rest of the mitigation site protected under a perpetual conservation
easement;
(C) stormwater runoff from overland flow shall drain towards the ditch;
(D) be between one and three feet in depth; and
(E) the entire length of the ditch shall have been in place prior to the effective date of the
applicable buffer rule.
The width of the restored or enhanced area shall not be less than 30 feet and shall not exceed 50
feet for crediting purposes. The applicant or mitigation provider shall provide a delineation of the
watershed draining to the ditch. The watershed draining to the ditch shall be at least four times
larger than the restored or enhanced area along the ditch. The perpetual conservation easement
shall include the ditch and the confluence of the ditch with the intermittent or perennial stream,
and provide language that prohibits future maintenance of the ditch. The proposal shall meet all
applicable requirements of Paragraph (n) of this Rule for restoration or enhancement.
(9) Stormwater Treatment Options. All stormwater treatment options shall meet the following
requirements:
(A) Structural options already required by other local, state, or federal rule or permit cannot
be used as alternative buffer mitigation credit, except to the extent such measure(s)
exceed the requirements of such rule or permit. Stormwater Best Management Practices
(BMPs), including bioretention facilities, constructed wetlands, infiltration devices and
sand filters are all potentially approvable BMPs by the Division for alternative buffer
mitigation credit. Other BMPs may be approved only if they meet the nutrient removal
levels outlined in Part (o)(9)(B) of this Rule. Existing or planned BMPs for a local, state,
or federal rule or permit may be retrofitted or expanded to improve their nutrient removal
if this level of treatment is not required by other local, state, or federal rules. In this case,
the predicted increase in nutrient removal may be counted toward alternative buffer
mitigation credit;
(B) Minimum treatment levels: Any structural BMP shall provide at least 30 percent total
nitrogen and 35 percent total phosphorus removal as demonstrated by a scientific and
engineering literature review as approved by the Division. The mitigation proposal shall
demonstrate that the proposed alternative removes an equal or greater annual mass load
of nutrients to surface waters as the buffer impact authorized in the authorization
certificate or variance, following the calculation of impact and mitigation areas pursuant
to Paragraphs (d), (e), and (f) of this Rule. To estimate the rate of nutrient removal of the
impacted buffer, the applicant or mitigation provider may use the "NC Division of Water
Quality — Methodology and Calculation for determining nutrient reductions associated
with Riparian Buffer Establishment" available at no cost at
http://portal.ncdenr.org/c/document_ library/get file?uuid=5 5 c3 758 f-5 e27-46cf-823 7-
47f890d9329a&groupId=38364. The applicant or mitigation provider may propose an
alternative method of estimating the rate of nutrient removal for consideration and review
by the Division;
(C) All proposed structural BMPs shall follow the Division's "2009 Stormwater Best
Management Practice Design Manual" available at no cost at

http://portal.ncdenr.org/web/Ir/bmp-manual. If a specific proposed structural BMP is not
addressed in this Manual, the applicant or mitigation provider shall follow Chapter 20 in
this Manual for approval;
(D) All structural options are required to have Division approved operation and maintenance
plans;
(E) All structural options are required to have continuous and perpetual maintenance and
shall follow the Division's "2009 Stormwater Best Management Practice Design
Manual";
(F) Upon completion of construction, the designer for the type of BMP installed shall certify
that the system was inspected during construction and that the BMP was constructed in
conformity with plans and specifications approved by the Division;
(G) Removal and replacement of structural options: If a structural option is proposed to be
removed and cannot be replaced on-site, then a structural or non-structural measure of
equal or better nutrient removal capacity, as determined by calculations submitted to and
approved by the Division, in a location as specified by Paragraphs (f) and (g) of this Rule
shall be constructed as a replacement;
(H) Renovation or repair of structural options: If the applicant, mitigation provider, or the
Division determines that a structural option must be renovated or repaired, it shall beh
renovated to provide equal or better nutrient removal capacity than as originally
designed; and
(1) Structural options, as well as their operation and maintenance, are the responsibility of
the landowner or easement holder unless the Division gives written approval for another
responsible party to operate and maintain them. Structural options shall be located in
recorded drainage easements for the purposes of operation and maintenance and shall
have recorded access easements to the nearest public right-of-way. These easements
shall be granted in favor of the party responsible for operating and maintaining the
structure, with a note that operation and maintenance is the responsibility of the
landowner, easement holder, or other responsible party.
(10) Approval for other alternative buffer mitigation options. Other alternativeriparian buffer
mitigation options not specified within this Rule may be submitted to the Division for review and
recommendation to the Environmental Management Commission on a case-by-case basis. Any
proposal submitted under this Paragraph shall provide documentation or calculations to
demonstrate that the proposed alternative mitigation option removes an equal or greater annual
mass load of nutrients to surface waters as a riparian buffer. Upon completion of the Division's
review, and prior to recommendation to the Environmental Management Commission, the
Division shall issue a 30 -calendar day public notice through the Division's website and the
DWRwetlands Listserve. Division staff shall present their recommendations, including comments
received during the public notice period, to the Environmental Management Commission for a
final decision. If approved by the Environmental Management Commission, the alternative buffer
mitigation option may be proposed by other applicants and mitigation providers.
