This instrument is made and entered into by KCI Technologies, Inc. acting as the Bank Sponsor ("Sponsor"), and the North Carolina Department of Environmental Quality - Division of Water Resources ("DWR"). This Instrument has been developed in accordance with 15A NCAC 02B.0240 and the Consolidated Mitigation Rule 15A NCAC 02B .0295, which became effective on November 1, 2015 (Attachments C and D, respectively). The purpose of this Bank Parcels is: A. To restore, enhancement and preserve riparian vegetation adjacent to mitigated streams and/or agricultural ditches with the intent to improve water quality within the Haw River Sub - watershed of the Jordan Lake Watershed. B. To convert agricultural land uses within riparian areas adjacent to mitigated streams and/or agricultural ditches into a dense, hardwood vegetated state with the intent to significantly reduce nutrient loadings associated with agricultural practices into streams and ditches. C. To provide mitigation and sell any resulting Riparian Buffer Credits and/or Nutrient Offset Credits to third parties in the Haw River Sub -watershed of Jordan Lake Watershed for development (both existing and proposed) requiring such mitigation. II. 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 Credit for impacts due to development activities. B. The GSA for this instrument is limited to the Haw River sub -watershed of Jordan Lake as defined in Rule 15A NCAC 02B .0262. C. Sale or transfer of Riparian Buffer Credits shall be limited to the Haw River Sub -watershed of the Jordan Lake watershed, as defined in Rule 15A NCAC 02B .0262, unless otherwise authorized by the DWR or delegated local government in accordance with 15A NCAC 02B .0295. D. Sale or transfer of delivered Nutrient Offset Credits shall also be limited to the Haw River Sub - watershed of the Jordan Lake watershed, as defined in Rule 15A NCAC 02B .0262 and in accordance with 15A NCAC 02B .0240 unless otherwise authorized by the DWR in accordance with Session Law 2019-86. E. The following table provides site -specific detail of each Bank Parcel proposed under this instrument.

AUTHORITIES Named Receiving Primary Land t USGS HUC Stream Use/s South Prong Crop Fields, )02040080 Stinking Quarter Cattle Pasture A. The Bank Parcel will be used to provide Riparian Buffer Credit and Nutrient Offset Credit in accordance with the requirements in the DWR Authority document referenced herein as "Attachment A" and attached to this Instrument. B. Projects eligible for utilization of the credits are those requiring authorization under the requirements of Attachment A and any subsequently approved North Carolina statutes and rules for the Jordan Lake Nutrient Sensitive Water Management Strategy. C. The selling of mitigation credits generated from the Bank Parcels approved under this Instrument shall be consistent with approved North Carolina statutes and rules for the Jordan Lake Nutrient Sensitive Waters Management Strategy. D. Mitigation activities proposed under this Instrument and corresponding Buffer Mitigation & Nutrient Offset Plan ("Plan") to generate Riparian Buffer Credits and Nutrient Offset Credits shall be consistent with North Carolina statutes and rules for the Jordan Lake Nutrient Sensitive Waters Management Strategy that are in place at the time a complete Plan is submitted to DWR. IV. ESTABLISHMENT OF THE BANK PARCEL(S) A. In accordance with 15A NCAC 026.0295 and 15A NCAC 02B .0240, DWR has provided a "Site Viability Letter" for the Bank Parcel proposed under this Instrument. The Site Viability Letter is not an approval of the site to generate mitigation credits, but is a preliminary review of the Bank Parcel that details and confirms existing land use conditions, defines the riparian sites (Enhancement Preservation, or Restoration), and identifies features (streams, ditches, ponds, etc.) that meet general criteria to be suitable to generate mitigation credits. Table 2.0 below outlines when a Site Viability Letter was issued by NCDWR for the mitigation sites proposed under this Instrument: 4 Table 2.0. Site Viability Letter Details Bank Parcel NC DWR Site Visit Viability Letter Received Viability Letter Expiration Date Black Bull Site October 15, 2018 November 15, 2018 November 15, 2020 B. A valid Site Viability Letter is required prior to submittal of each Plan. Site Viability Letters will either expire on the dates listed in the table above or upon submittal of an individual As -Built Report to the DWR, whichever comes first. If a Site Viability Letter expires prior to submittal of a complete Plan as described in Section V to DWR, then the Sponsor must submit a formal request to DWR for a new Site Viability Letter for that Bank Parcel. C. The Bank Parcel proposed for inclusion under this Instrument shall require a Buffer Mitigation & Nutrient Offset Plan ("Plan") be submitted to, and approved, by the DWR prior to use of the individual Bank Parcel for mitigation purposes or the sale or transfer of any associated credits. The contents of each Plan are provided in Section V. D. This Bank Parcel is also proposed under the KCI Cape Fear 02 Umbrella Mitigation Banking Instrument (KCI Cape Fear 02 UMBI), United States Army Corps of Engineers (USACE) Action ID #SAW-2018-00967 for stream and wetland mitigation. The KCI Cape Fear 02 UMBI and the site - specific Mitigation Plan for the Black Bull Site, were submitted to the IRT for review and approval. E. The Plan submitted under this instrument will be placed on public notice and made available for public commenting for 15 calendar days. F. Most of the Riparian Buffer Credits on the Bank Parcel will be generated along restored stream channels that are proposed for stream mitigation. Stream Mitigation Plans will be submitted under the KCI Cape Fear 02 UMBI referenced in "D" in this section. Additionally, all activities conducted within riparian buffers and adjacent riparian areas for purposes of generating Riparian Buffer Credits or Nutrient Offset Credits will be conducted in concurrence with stream and wetland mitigation activities. In general, the Bank Sponsor expects all buffer mitigation credits to be generated through restoration, enhancement and/or preservation of DWR riparian buffers as they are defined in 15A NCAC 02B.0267, and other riparian areas as allowed per 1SA NCAC 02B .0295 (n) and (o). Riparian Buffer Credits are only attainable if the width of the mitigated area is at least 20 feet as measured perpendicular from top of banks. G. The Bank Parcel is intended to provide Jordan lake Riparian Buffer Credit as follows: 1. Planting hardwood trees and shrubs on a Restoration Site as defined in 15A NCAC 028.0295, (b) adjacent to mitigated streams. 2. Maintaining a Preservation Site as defined in 15A NCAC 02B .0295 (b) along streams allowed in 15A NCAC 02B .0295 (o) by placing a conservation easement around riparian areas. 3. Enhancing riparian areas that are being grazed by cattle by installing fencing to permanently exclude cattle from the streams and their associated riparian areas as allowed in 15A NCAC 02B .0295 (o)(6). 4. Diffused flow will be maintained onsite to the maximum extent practicable. H. Nutrient Offset Credit maybe achieved on these Bank Parcels through restoration of riparian areas, where agriculture is the predominant land use. The width of the restoration area begins at the most landward limit top of the bank or the rooted herbaceous vegetation and extends landward a minimum of 50' and a maximum of 200 feet on all sides of the surface waters. I. The Bank Parcel will provide Nutrient Offset Credit in accordance with 15A NCAC 02B .0240 and is expected to provide Nutrient Offset Credit as follows: 1. Converting agricultural land uses within riparian areas to non-agricultural land uses. 2. Planting hardwood trees and shrubs on a Restoration Site as defined in 15A NCAC 0213.0295 (b) adjacent to streams where agriculture has been determined to be the predominant land use. J. The Bank Parcels submitted for review under this Instrument is anticipated to begin construction of stream and wetland mitigation activities in the spring of 2020. V. BUFFER MITIGATION & NUTRIENT OFFSET PLAN A. The Plans submitted under this Instrument shall be submitted to DWR for review and must be approved by DWR prior to any construction on the Bank Parcel. The Plan must describe any changes that have occurred to the site between the date of the Site Viability Letter and the date the Plan is submitted to DWR. The Plan shall include detailed information consistent with the sections below concerning; 1) site location (14-digit HUC is required); 2) existing conditions with current photos; 3) proposed buffer mitigation and nutrient offset activities including a detailed vegetation plan; 4) monitoring and maintenance plans; 5) financial assurances; 6) associated buffer mitigation/nutrient credit calculations, which shall include credit generation, service area, and accounting as appropriate for each regulatory authority; 7) stream buffer determination letter from DWR; 8) Site Viability Letter from DWR; 9) a figure depicting the proposed stream 6 and wetland mitigation areas; and 10) service area figure for each mitigation type. B. The Sponsor will obtain all applicable federal, state and local documentation, permits, or authorizations needed to construct and maintain the Bank Parcel. This Instrument does not qualify as, or substitute for, such documentation, permit, or authorization. C. Any restoration and/or enhancement activities or proposed construction within the riparian buffers and other riparian areas on the Bank Parcel to produce Riparian Buffer Credit or Nutrient Offset Credit must be approved by DWR in writing prior to implementation. The failure of the Sponsor to comply with this requirement may result in a revised or reduced credit release schedule for that specific Bank Parcels. All restoration and enhancement activities must be performed in concurrence with any stream or wetland mitigation activities and not before. D. Requests for deviation from the approved Plan must be submitted to DWR in writing. Written approval from the DWR must be received prior to implementing any deviation from the approved Plan. Property Disposition & Long Term Management for Each Bank Parcel E. Prior to the release of any credits, the Sponsor shall record permanent conservation easements at the Alamance County Register of Deed's office that are sufficient to ensure protection, operation, and maintenance of restored riparian buffers and other riparian areas for the duration specified in the approved Plan. F. The form of the conservation easement shall be consistent with the standards employed by the State of North Carolina in the protection of restored riparian buffers and riparian areas and shall be approved by the DWR and Army Corps of Engineers (ACOE) prior to the release of any credits. G. The Sponsor shall not grant additional easements, right of ways, or any other property interest in or to the project areas, without prior approval from the DWR. H. The Sponsor agrees to transfer or assign the conservation easement and its interests in perpetuity to a qualified holder under NC General Statute ("GS")121-34 et seq. and 170(h) of the Internal Revenue Code prior to the submittal of the Year 4 Monitoring Report. The holder shall be a land trust or stewardship program that will hold and enforce the conservation easement and the interests in perpetuity. The Sponsor shall choose a land trust or stewardship program that is accredited by the Land Trust Accreditation Commission and/or has been approved by DWR prior to the end of the fourth year monitoring period. A land trust must be certified under 501(c)(3) of the Internal Revenue Code. 7 I. In the event the Sponsor is also the owner of the underlying fee interest in the property the conveyance of the conservation easement to a land trust or stewardship fund must be arranged at the outset of the approved Plan. Financial Assurances for the Bank Parcel J. Following approval of the Plan for each Bank Parcel, the Sponsor shall provide Performance/Maintenance Bonds from a surety company that is rated no less than an "A-" as rated by A.M. Best, to construct the Bank Parcel according to the approved Plan. It is the Sponsor's responsibility to confirm that the surety company is rated no less than an "A-" with each annual bond renewal. K. The amount of the Performance Bond shall be 100% of the estimated cost for implementation of the mitigation activities of the Bank Parcel as described in the approved Plan. No bond shall be less than $150,000.00 to cover construction costs. L. Alternatively, in lieu of posting a Performance Bond, the Sponsor may elect to construct the project prior to the first credit release. M.

Aerial map of the mitigation that was included in the approved Plan. 6. As -built map of the stream and/or wetland mitigation areas. Financial Assurances for Each Bank Parcel C. After completion of the restoration/construction on each Bank Parcel, a separate Performance/ Maintenance Bond will be secured for 100% of the estimated cost to implement the monitoring and maintenance plan as described in the approved Plan and As -Built Report. The Bond must be from a surety company that is rated no less than an "A -'as rated by A.M. Best, and it is the Sponsor's responsibility to confirm the surety company is still rated no less than an "A-" with each annual bond renewals. D. A Performance/Maintenance Bond shall be secured each year for a minimum of five years, and until DWR has released all mitigation credits to the Bank Sponsor. Upon DWR approval, the bond may be lowered each year based on the adjusted cost to complete the monitoring. No bond shall be less than $100,000 to cover monitoring and maintenance costs. 9 E. For the Bank Parcel, once DWR has released 100% of all credits for completion of all Bank Parcel milestones described in Table 5 of Section VIII and in the corresponding Plan, the Bank Sponsor will be released from its performance obligations under the performance bond required in C and D in this section. F. To comply with this section, DWR must be the Obligee on all performance bonds. Monitoring -and Maintenance G. The Sponsor shall monitor the Bank Parcel as described in the Plan until such time as DWR determines that the performance standards described below have been met. The monitoring period shall be a minimum of five consecutive years. H. Performance Standards for Vegetation: Native hardwood trees or native hardwood tree and shrub species should be planted at a density sufficient to provide 260 stems per acre after five years. A minimum of four (4) native hardwood trees or four (4) native hardwood tree and shrub species must be planted. No one species shall be greater than 50% of the planted stems. A list of species for planting will be detailed in the Plan for approval. Native hardwood tree volunteer species may be included to meet performance standards as determined by the DWR. I. A "stem" means a woody seedling, sapling, shrub or tree, no less than 10 centimeters in height. J. If the performance standards of the vegetation are not met, supplemental plantings may be required. Supplemental plantings will be utilized until the required densities have been achieved and maintained for five years. Bank Parcel maintenance, such as ensuring diffused flow, managing invasive species, and pest control will be included in the Plan. Monitoring Reports for Riparian Buffer Credit and Nutrient Offset Credit K. Reporting criteria of the vegetation shall be based on the Carolina Vegetation Survey (CVS) - EEP Protocol for Recording Vegetation Level 2 Plot Sampling only version 4.0 or any updated versions of this protocol in place at the date of acceptance of the Plan. The Sponsor shall submit to the DWR an annual monitoring report no later than December 31st of each year for a minimum of five consecutive years after the first full growing season. This report will describe the conditions of each Bank Parcel, including an evaluation of the performance standards of the vegetation contained within the approved Plan. Reports shall contain the following: 1. A U.S. Geological Survey map showing location of the Bank Parcel; 2. A detailed narrative with supporting photos summarizing the condition of the Bank Parcel along with any maintenance or remediation performed that year; and 10 3. A map, survey, or other figures showing locations of sampling plots, permanent photo points, and location of transects, Etc.; and 4. Monitoring data, including specific vegetation counts showing that the trees or tree and shrub species planted are meeting performance standards and updated photographs; and 5. A copy of the most recent Bank credit/debit lodgers; and 6. Corresponding verification letters from designated local governments upon request; and 7.

In the event a Bank Parcel fails to achieve the performance criteria described in this Instrument and in the approved Plan, the Bank Sponsor shall develop necessary contingency plans in coordination with the DWR and implement appropriate remedial actions for the Bank Parcels and the Bank. Depending on the degree remedial actions required, the DWR may modify the monitoring period. VII. CALCULATION OF MITIGATION CREDITS FOR THE BANK PARCEL Riparian Buffer Credits A. All Riparian Buffer Credits shall be determined based on the ratios and percentages provided in 15A NCAC 02B .0295 (m) and (n). B. Riparian buffer restoration as described in 15A NCAC 02B .0295 (n) or (o) and defined in 15A NCAC 02B .0295 (b) and performed on agriculture lands within the Bank Parcels, may be used for either Riparian Buffer Credit or Nutrient Offset Credit but not both. Riparian restoration on non -agriculture lands can only be used for Riparian Buffer Credit. C. Riparian buffer enhancement on these Bank Parcels, as described in 15A NCAC 026 .0295 (o)(6), can only be used for Riparian Buffer Credit. D. Riparian buffer preservation on the Bank Parcel, as described in 15A NCAC 02B .0295 (o) (5) and defined in 15A NCAC 02B .0295 (b), can only be used for Riparian Buffer Credit. E. Riparian Buffer Credit is defined as one (1) buffer credit per one square foot or 43,560 buffer credits per one acre. 11 F. Pursuant to 15A NCAC 02B .0295 (1)(6)(B), "Buffer mitigation credit shall not be generated within wetlands that provide mitigation credit required by 15A NCAC 02H .0506". Nutrient Offset Credits G. The acreage of Nutrient Offset Credits on the Bank Parcel submitted under this Instrument is determined by applying the applicable ratio as provided in 15A NCAC 02B .0295 (m) for a Restoration Site. All riparian areas proposed for Nutrient Offset Credits must be a minimum of fifty (50) feet from the top of the stream or ditch banks on land noted in the site viability letter as agriculture. H. Nutrient Offset Credits cannot be achieved on the Bank Parcels in areas where preservation activities are performed or where enhancement is proposed under 15A NCAC 02B .0295 (o)(6). I. Nutrient Abatement of Restored Riparian Areas on Agricultural Lands: The Sponsor and DWR agree to the following: 1. Pursuant to the Jordan Trading Rule Item 15A NCAC 02B .0273 (2)(a), load reductions eligible for credit are only those that exceed reduction needs calculated by applying the strategy sub -watershed percentage reduction goals as provided in 15A NCAC 02B .0262 (5). For the Haw River Sub -watershed, this requirement results in a reduction of credits yielded per acre for restored riparian buffers when compared with the credit given in other river basins. Table 3.0 below lists the generated credit per acre of restored riparian buffer for the Haw -River Sub -watershed. Table 3.0. Generated Credit Yield for Forest Buffer Restoration in the Haw Sub -watershed. Credit Generated (lbs./30 yrs./ac.) Jordan Lake Sub -watershed Nitrogen Phosphorus Haw River 2,249.36 143.81 J. As required under Jordan Trading Item 15A NCAC 02B .0273 (2)(d)(i), the party seeking to sell credits must account for differences in instream nutrient losses between the location of the reduction need and excess loading reduction being delivered to the affected area of Jordan Lake. Attachment B produced the delivered Jordan Lake Total Nitrogen (TN) and Jordan lake Total Phosphorous (TP) credit yields per acre of buffer restoration by each Jordan Lake 14-Digit HUC sub -watershed. 1. Delivered credits are calculated by applying the delivery factors in Table 4.0 below and the acreage of riparian restoration to the generated credit yields from Table 3.0 above. The . delivery factors for the Bank Parcel under this Instrument for Total Nitrogen (TN) and Total Phosphorus (TP) are provided in Table 4.0 below using Attachment B for reference. The 12 amount of delivered credits for the Bank Parcel will be detailed in the Plan for each Bank Parcel. Table 4.0. Delivery Factors Delivery Factors TN TP Black Bull 53% 51% The Bank Sponsor shall report the pounds of nitrogen and phosphorus credit per acre of restored riparian buffer in each Bank Parcel's Plan for both credits generated at the site of the nutrient reduction activity and the credits delivered to Jordan Lake. K. The Sponsor and DWR agree the methodology and calculations for determining nitrogen and total phosphorous reduction, associated with restoration of riparian areas as described in Section IV of this Instrument, shall be fixed as part of the approval of this Instrument, with the fixed amount not changing during Plan Development or credit release schedule for the Bank Parcel unless the viability letter for that Bank Parcel has expired. 13 Vlll. CREDIT RELEASE SCHEDULE A. Upon submittal of all appropriate documentation by the Sponsor, and subsequent approval by DWR, it is agreed that the mitigation credits associated with each individual Bank Parcel will become available for sale to a third party in accordance with the Credit Release Schedule below.

Page 2 of 2 Attachment C: Rule Text 15A NCAC 02B .0240 15A NCAC 02B .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 nutrientstrategy, (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 allowthis 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 impactsto 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 thisRule; (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 underrules 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-govemmental 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.

(1) MITIGATION SITE REQUIREMENTS FOR APPLICANTS AND MITIGATION PROVIDERS. For each mitigation site proposed by an applicant or mitigation provider under Paragraphs (n) or (o) of this Rule, the Authority shall identify functional criteria to measure the anticipated benefits of the mitigation to the adjacent water. The Authority shall issue a mitigation determination that specifies the area, type, and location of mitigation and the water quality benefits to be provided by the mitigation site. All mitigation proposals shall meet the following criteria: (1) The location of the buffer mitigation site shall comply with the requirements of Paragraphs (f) and (g) of this Rule. In the Catawba watershed, buffer mitigation may be done along the lake shoreline as well as along intermittent and perennial stream channels throughout the watershed. (2) The mitigation proposal shall include a commitment to provide: (A) a perpetual conservation easement or similar preservation mechanism to ensure perpetual stewardship that protects the mitigation site's nutrient removal and other water quality functions; (B) a non -wasting endowment or other dedicated financial surety to provide for the perpetual land management and hydrological maintenance of lands and maintenance of structures as applicable; and (C) financial assurance in the form of a completion bond, credit insurance, letter of credit, escrow, or other vehicle acceptable to the Authority payable to, or for the benefit of, the Authority in an amount sufficient to ensure that the property is secured in fee title or by easement, and that planting or construction, monitoring and maintenance are completed as necessary to meet success criteria as specified in the approved mitigation plan. This financial assurance obligation shall not apply to the NC DMS. (3) Diffuse flow of runoff shall be maintained in the riparian buffer. Any existing impervious cover or stormwater conveyances such as ditches, pipes, or drain tiles shall be eliminated and the flow converted to diffuse flow. If the applicant or mitigation provider determines that elimination of existing stormwater conveyances is not feasible, then they shall include a justification and shall provide a delineation of the watershed draining to the stormwater outfall and the percentage of the 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. (5) The applicant or mitigation provider shall provide a site specific credit/debit ledger to the Authority at regular intervals as specified in the mitigation plan approval or mitigation banking instrument once credits are established and until they are exhausted. (6) Buffer mitigation credit, nutrient offset credit, wetland mitigation credit, and stream mitigation credit shall be accounted for in accordance with the following: (A) Buffer mitigation used for buffer mitigation credit shall not be used for nutrient offset credits; (B) Buffer mitigation credit shall not be generated within wetlands that provide wetland mitigation credit required by 15A NCAC 02H .0506; and (C) Buffer mitigation credit may be generated on stream mitigation sites as long as the width of the restored or enhanced riparian buffer meets the requirements of Subparagraph (n)(1) of this Rule. (m) RIPARIAN BUFFER MITIGATION UNITS.

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 (o)(4) or (o)(5) of this Rule for preservation. (8) Restoration and Enhancement on Ditches.

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 ofthe 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=55 c3 758 f-5e27-46cf-8237- 47t890d9329a&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; (I) 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 be renovated to provide equal or better nutrient removal capacity than as originally designed; and (I) 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 alternative riparian 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.
