PREAMBLE This Mitigation Banking Instrument ("Instrument") regarding the establishment, use, operation, and maintenance of the North Fork Little River Nutrient and Buffer Mitigation Bank Parcel ("Bank Parcel") to provide Neuse Riparian Buffer mitigation credit ("Riparian Buffer Credits") and Falls Lake Water Supply nutrient load reduction credit ("Nutrient Offset Credits") is made and entered into by and among Wildlands Holdings II, 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 Mitigation Rule 15A NCAC 02B .0295, which became effective on November 1, 2015 (Attachments E and F). The purpose of the Bank is: A. To improve water quality of tributaries to the North Fork Little River through the restoration of riparian buffer habitat and adjacent riparian areas. B. To provide mitigation and sell any resulting Riparian Buffer Credits and/or Nutrient Offset Credits to third parties in the Neuse River Basin and Falls Lake Watershed respectively, 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 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 of the Upper Falls Watersheds as defined in 15A NCAC 02B .0276. C. The project is comprised of one parcel of land in Durham County, NC. The property is currently in row crop production for corn and is accessed from 10119 S. Lowell Road, in Bahama, NC. The project is located at 36.1693 N and 78.9304W. D. Unnamed tributaries to the North Fork Little River are the receiving bodies of water for stormwater runoff from this parcel. The North Fork Little River 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 in which the Bank Parcel is located unless otherwise authorized by the DWR or delegated local government in accordance with 15A NCAC 02B .0295. F. Sale or transfer of Nutrient Offset Credits shall be limited to the Falls Lake Watershed, as defined in Rule 15A NCAC 02B .0276 and in accordance with 15A NCAC 02B .0282 (2). 2 III.AUTHORITIES A. The Bank 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 new approved North Carolina ("State") statutes and rules for the Neuse Nutrient Sensitive Waters Management Strategy — and- for the Falls Lake Water Supply Nutrient Strategy. C. All activities, including the sale of mitigation credits shall be consistent with approved North Carolina ("State") statutes and rules for the Neuse Nutrient Sensitive Waters Management Strategy —and- for the Falls Lake Water Supply Nutrient Strategy. IV. ESTABLISHMENT OF NORTH FORK LITTLE RIVER BANK PARCEL A. The Bank Parcel proposed for inclusion under this Instrument shall require a Bank Parcel Development Package ("BPDP") be submitted to, and approved by, the DWR prior to use of the Bank Parcel for mitigation purposes or sale or transfer of any associated credits. The contents of the BPDP are provided in Section V. B. The BPDP will be placed on public notice and made available for public commenting for 15 calendar days. C. Riparian Buffer Credit may be achieved through restoration of DWR riparian buffers along the unnamed tributaries on the Bank Parcel according to 15A NCAC 02B .0295 (n), and riparian areas along some ditches as allowed in 15A NCAC 02B .0295 (o). D. The Bank Parcel is intended to provide Neuse Riparian Buffer mitigation as follows: I . Planting hardwood trees on a Restoration Site, as defined in 15A NCAC 02B .0295 (b) and (n) along three streams which are intermittent and are subject to the buffer protection rule 15A NCAC .0233. 2. Planting hardwood trees on a Restoration Site, as defined in 15A NCAC 02B .0295 (n) along agricultural ditches that meet all of the criteria under 15A NCAC 02B .0295 (o). The width of the restored area will be a minimum of 30 feet and will not exceed 50 feet for crediting purposes. All ditches proposed for alternative buffer mitigation, must be approved by the DWR as part of the BPDP prior to implementing the ditches for buffer mitigation. 3. Diffuse flow will be maintained onsite to the maximum extent practicable. Where diffuse flow is unattainable, the Bank Sponsor may elect to use the Buffer Interpretation/Clarification Memo 42008-019 dated August 19, 2008 which is provided as Attachment B. E. Nutrient Offset Credit may be achieved through restoration of the riparian areas adjacent to streams and agricultural ditches on the Bank Parcel that drain to the unnamed tributaries onsite or to North Fork Creek. The width of the restoration area begins at the most landward limit of the top of bank or the rooted herbaceous vegetation and extends landward a maximum of 200 feet on all sides of the surface waters. F. The Bank Parcel is expected to provide Nutrient Offsets as follows: 1. Planting hardwood trees on a Restoration Site, as defined in 15A NCAC 2B .0295 (b) and per 15A NCAC 02B .0295 (n) (2) along intermittent streams on the Bank Parcel. Current land use along the streams is corn production. 2. Planting hardwood trees on a Restoration Site, as defined in 15A NCAC 2B .0295 (b) and per 15A NCAC 02B .0295 (n) (2) along agricultural ditches on the Bank Parcel. Current land use along the ditches is corn production. G. The total area of mitigation on the Bank Parcel is expected to be 33 acres. V. BANK PARCEL DEVELOPMENT PACKAGE A. The North Fork Little River Bank Parcel Development Package (BPDP) shall include detailed information consistent with the sections below concerning: 1) site location (8 -digit HUC is required); 2) existing conditions; 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, and 8) site viability letter from DWR. 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. The restoration of riparian buffers and other riparian areas on the Bank Parcel to produce Riparian Buffer Credit or Nutrient Offset Credit must be approved by DWR prior to construction. D. Requests for deviation from the approved BPDP must be submitted to DWR in writing. Written approval from the DWR must be received prior to implementing any deviation from the approved BPDP. Property Disposition & Long Term Management E. Prior to the release of any credits, the Sponsor shall acquire a permanent conservation easement at the County Register of Deed's office that is sufficient to ensure protection, operation and maintenance of restored riparian buffers and other riparian areas for the duration specified in the approved BPDP. rd 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 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. I. In the event that 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 BPDP. Financial Assurances J. Following approval of the BPDP, the Sponsor shall provide a Performance/Maintenance Bond 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 that the surety company is still rated no less than an "A-" with each annual bond renewal. The Performance Bond amount shall be 100% of the estimated cost for implementation of the mitigation activities of the Bank Parcel as described in the approved BPDP. No bond shall be less than $150,000.00 to cover construction costs. K. Alternatively, in lieu of posting the Performance Bond, the Sponsor may elect to construct the project prior to the first credit release. L. Once DWR has released all credits for completion of Task 2 according to the credit release schedule in Section VIII and the DWR has received the As -Built Report as described in Section VI and submitted a written approval, the Bank Sponsor can be released from its performance obligations under the performance bond required in "J" of this section. VI. POST CONSTRUCTION DOCUMENTATION As -Built Report A. The Sponsor agrees to perform all necessary work, in accordance with the provisions of this Instrument, to establish, maintain, and monitor Neuse Riparian Buffers or other riparian areas until Item B (1) and (2) of Section X have been satisfied. B. The Sponsor will submit an as -built plan and report for the Bank Parcel within 30 calendar days after completing the establishment of the buffer area and nutrient offset area. The as - built report will describe any deviation from the approved BPDP and will document the following: Buffer restoration: planting details, invasive species control, monitoring device locations, vegetation plot locations, photo point locations, surface and groundwater elevations, as appropriate. 2. Boundary Survey of the conservation easement area, signed and sealed by a licensed surveyor, including an enumeration of the final mitigation areas for riparian buffer and/or nutrient offset mitigation credits in both square feet and acres. 3. As -built aerial map of the mitigation area showing where restoration was performed 4. Aerial map of the mitigation that was included in the approved BPDP. Financial Assurance C. After completion of the restoration/construction, 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 BPDP. 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 that the surety company is still rated no less than an "A-" with each annual bond renewal. 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. D. Once DWR has released all credits for completion of Tasks 1-9 according to the credit release schedule in Section VIII, the Bank Sponsor can be released from its performance obligations under the performance bond required in "C" of this Section. Monitoring and Maintenance Reports E. The Sponsor shall monitor the Bank Parcel as described in the BPDP until such time as DWR determines that the success criteria described below have been met. The monitoring period shall be a minimum of five consecutive years. F. 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 2 planted stems. A list of species for planting will be detailed in the BPDP for approval. Native hardwood tree volunteer species may be included to meet performance standards as determined by the DWR. G. A "stem" means a woody seedling, sapling, shrub or tree, no less than 10 centimeters in height. H. 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 diffuse flow, managing invasive species, and pest control will be included in the BPDP. I. Monitoring Reports for Riparian Buffer Credit or Nutrient Offset Credit: Reporting criteria of the riparian buffer restoration 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 BPDP. The Sponsor shall submit to the DWR an annual monitoring report no later than December 31 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 BPDP. Reports shall contain the following: 1. A U.S. Geological Survey map showing location of the Bank Parcel; 2. A detailed narrative summarizing the condition of the Bank Parcel along with any maintenance or remediation performed that year; and A map, survey, or other figure showing locations of sampling plots, permanent photo points, location of transects, etc.; and 4. Monitoring data, including specific vegetative 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 ledgers; and 6. Corresponding verification letters from designated local governments upon request; and 7. Corresponding Mitigation Transfer Certificates upon request. Contingency Plans/Remedial Actions J. In the event the Bank Parcel fails to achieve the success criteria described in this Instrument and the approved BPDP, the Bank Sponsor shall develop necessary contingency plans in VA coordination with the DWR and implement appropriate remedial actions for the Bank Parcel and the Bank. Depending on the degree of remedial actions required, the DWR may modify the monitoring period. VII. CALCULATION OF MITIGATION CREDITS 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 on the Bank Parcel, as defined in 15A NCAC 02B .0295, may be used for either Riparian Buffer Credit or Nutrient Offset Credit, but not both. C. Riparian Buffer Credit is defined as one (1) buffer credit per one square foot or 43,560 buffer credits per one acre. Nutrient Offset Credits D. All Nutrient Offset Credits will be determined by including the applicable ratio as provided in 15A NCAC 02B .0295 (m) for a Restoration Site. E. Nutrient Offset Credit may be achieved through restoration or enhancement of the riparian area adjacent to surface water features. Surface water features do not have to be intermittent or perennial, nor do they have to be depicted on a USGS, NRCS, or EMC approved map. However, surface water features must be hydrologically connected to and drain to jurisdictional waters that are either intermittent or perennial. The width of the restoration area begins at the most landward limit of the top of bank or the rooted herbaceous vegetation and extends landward a maximum distance of 200 feet on all sides of the surface water. F. Nutrient Abatement of Restored Riparian Area: The Sponsor and DWR agree: The pounds of nitrogen offset per acre of restored riparian areas shall be two thousand two hundred and seventy three pounds per acre (2,273.02 lbs/acre) or the amount of nitrogen offset per acre in effect at the time the BPDP is approved. 2. The pounds of phosphorus offset per acre of restored riparian areas shall be one hundred forty six and four -tenths pounds per acre (146.4 lbs/acre) or the amount of phosphorus offset per acre in effect at the time the BPDP is approved. G. The Sponsor and DWR agree that the methodology and calculations for determining nitrogen and total phosphorous reduction, associated with restoration of riparian areas, shall be fixed as part of the approval of each BPDP, with the fixed amount not changing during the development or credit release schedule for each Bank Parcel. This space left blank intentionally, do not add text to this space. VIII. CREDIT RELEASE SCHEDULE A. Credit Release: Upon submittal of all appropriate documentation by the Sponsor, and subsequent approval by DWR, it is agreed that the mitigation credits associated with the Bank Parcel will become available for sale to a third party in accordance with the following schedules: Table I - Credit Release Schedule for Riparian Buffer and Nutrient Offset Credits Task Project Milestone % Credit Available for Sale 1 MBI and BPDP Approved by DWR, Conservation Easement Recorded* and Financial Assurance Posted 20 2 Mitigation Site Earthwork, Planting and Installation of Monitoring Devices 1 Completed 20 3 Monitoring Financial Assurance Posted and Approval of As -Built Report 10 4 Monitoring Report #1: Approved by the DWR** 10 5 Monitoring Report #2: Approved by the DWR** 10 6 Monitoring Report #3: Approved by the DWR** 10 7 Item B (1) of Section X in this Instrument has been completed and approved by DWR. 5 No remaining credits will be released until Task 7 has been satisfied 8 Monitoring Report #4: Approved by the DWR** 5 9 Monitoring Report #5: Approved by the DWR** and final site visit by DWR has been conducted 10 Total 100% * For specification, please see Section V in this Instrument ** DWR Approval provided upon a determination that the site is meeting success criteria contained within the approved BPDP B.

The Bank Sponsor shall maintain three credit ledgers, if applicable, for the Bank Parcel under this Instrument: one accounting for buffer mitigation credits in square feet and acres, one accounting for nitrogen offset credits in pounds and acres, and one accounting for phosphorus offset credits in pounds and acres. B. Each credit ledger shall be submitted on a separate 8 ''/zin X 11 in spreadsheet with legible font style and font size. All ledgers shall be submitted using the templates provided in Attachments C and D of this Instrument or any updated versions to these templates as provided by DWR. 10 Credit Processine C. Riparian Buffer Credits generated on this Bank Parcel must be provided to offset impacts within the Neuse River Basin according to 15A NCAC 02B .0295 (g). D. Nutrient Offset Credits generated on this Bank Parcel can only be provided to offset nutrient loadings within the Upper and Lower Falls Watersheds. Impacted areas in the Upper Falls Watershed can only mitigate in the Upper Falls Watershed. Impacted areas in the Lower Falls Watershed can mitigate in any portion of the Falls Watershed per 15A NCAC 0213 .0282. E. Available mitigation credits (credits that have been released by DWR but not sold by the Sponsor) that are generated from riparian buffer restoration, as defined in 15A NCAC 02B .0295 (b) and described in 15A NCAC 02B .0295 (n) along intermittent streams can be converted and transferred from Riparian Buffer Credits to Nutrient Offset Credits and from Nutrient Offset Credits back to Riparian Buffer Credits upon written approval from DWR. F. Available mitigation credits that are generated from riparian restoration, as defined in 15A NCAC 02B .0295 (b) and described in 15A NCAC 02B .0295 (n) along approved ditches, may be converted from Nutrient Offset Credits to Riparian Buffer Credits and from Riparian Buffer Credits back to Nutrient Offset Credits. All Ratios and percentages of full credit will be applied to Riparian Buffer Credits according to 15A NCAC 02B .0295 (m) and (n) and ratios will be applied to Nutrient Offset Credits according to 15A NCAC 02B .0295 (m). G. The Bank Sponsor shall obtain verification of nutrient offset need from a designated local government in the Falls Watershed prior to debiting Nutrient Offset Credits from the Bank Parcel. H. The Bank Sponsor shall obtain verification of buffer mitigation required from the delegated local government or DWR prior to debiting Riparian Buffer Credits from the Bank Parcel. All credit and debit transactions for each Bank Parcel under this Instrument shall be accurately depicted in the credit ledgers. DWR shall be notified of each credit sale or credit transfer within thirty (30) calendar days by electronically submitting an updated credit ledger to DWR. At a minimum, DWR shall receive a hard copy of updated credit ledgers along with the corresponding Mitigation Credit Transfer Certificates ("Certificate") and all corresponding letters from the designated local governments twice a year. Notification of all credit sales shall be provided to DWR until all credits that have been released have been sold. 11 Mitigation Credit Transfer Certificates J. All credit sales will include a Mitigation Credit Transfer Certificate ("Certificate") that is required to be provided to the buyer of Riparian Buffer and/or Nutrient Offset credits, that will include, at a minimum, the following information: 1. Bank Details: (1) sponsor Name, (2) name of the approved banking instrument as it appears on the instrument document, (3) bank parcel name as it appears on the BPDP, (4) DWR project number for the BPDP. 2. Credit Details: (1) date of receipt, (2) identify if full or partial payment, (3 — when applicable) amount of nitrogen credits purchased in pounds and confirmation from the designated local government of the amount required, (4 — when applicable) amount of phosphorous credits purchased in pounds and confirmation from the designated local government of the amount required, and (5 — when applicable) amount of Riparian Buffer Credits purchased in square feet and the confirmation from DWR or the local government of the amount required. 3.

K. If the DWR determines that the Bank is operating at a deficit (e.g. the Sponsor is closing on sales and/or transferring credit that is not available), or the Bank is selling credits out of compliance with statutes, rules or this Agreement, the sale/transfer of credits will immediately cease, and the DWR, in consultation with the Sponsor, will determine what remedial actions are necessary. X. BANK PARCEL CLOSURE A. Bank Parcel Closure shall be identified as the event when the Sponsor is relieved of all of its responsibilities to the Bank Parcel and there are no mitigation credits left to sell. B. Bank Parcel Closure shall commence only after all of the following events have occurred: 1. Transfer or assign the conservation easement and all of its interests, in perpetuity, to a land trust or stewardship program as described in Section V of this instrument. 2. All five years of monitoring completed and all monitoring reports submitted and approved by DWR 3.

Diffuse tlo~% is a requirement for buffer restoration or enhancement in the Neuse River Ba in Buffer Rule 15A NCAC 02B.0242(9)(d)(iii), the Tar -Pamlico River Basin Buffer Rule 15A NCAC 02B.0260(9)(d)(iii), and the Caiawba River Basin Buffer Rule ISA NCAC 0213.0244 (9)(d)(iii). Diffuse Ilow is a requirement for all sites in a buffered basin for buffer mitigation and for for sites providing nutrient offset credit as �k ell. Current Polio•: According to the Mitigation rules in the Neuse. Tar -Pamlico and Catawba buffer rules, a grading plan must be proti ided (lir butler mitigation sites. In addition. those rules state that "The site shall be graded in a manner to ensure diffuse flow thruu=ii the riparian buffer". Prubl nig I he question has been raised as to whether stormwater carried by lateral ditches that enter buffered streams should proridc dtlfu�e 11(m prior 10 that storntwater entering the restored butlers. "'iilutiow t he Neuse, Tar -Pamlico and Catawba buffer rules with respect to buffer mitigation sites contain a very= clear requirement that states that diffuse flow of stormwater must be maintained through the buffer, unless otherwise approved by DWQ, all buffer miii�aation sites must provide difltise Ilow of stormwater from ditches and similar conve)'anew throu-h the restored bufi'er.

To calculate the area of buffer being "short-circuited" by the ditch, the area of the right triangles shown in the figure above must be determined. a=50' A=30° B = 60° b=acot A b = 50 (1.732) b = 86.6' (87') The area to be excluded from credit would be the area of the two right triangles: Area = (a x b)/2 Area = (50 feet x 87feet)/2 Area = 2,175 SF Total deducted area = 2,175 x 2 = 4,350 SF or 0.1 acres. The example shown above assumes a buffer width of 50 feet from the top of bank (riparian buffer mitigation site). For nutrient offset sites, credit can be generated out to 200 feet from the top of bank. The policy applies to sites with larger buffers as follows: SCENARIO 2 401 Wetlands Certification Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone. 919-733-1786 / FAX 919-733-6893 ; Internet: http:/Al2o.enr.state.nc,us/nc,. etiands An Equal Opponunity/Aflinnative Action Employer— 50% Recycled/10% Post Consumer Paper Noce hCarol ina atumilil Page 3 of 4 I! a bitch leading to a buffered stream is buffered. then no credit is deducted from the stream buffer.

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. Mitigation activities shall generate riparian buffer mitigation units as follows: Mitigation Activity Square Feet of Mitigation Buffer Riparian Buffer Mitigation Units Generated Restoration Site 1 1 Enhancement Site 2 1 Preservation Site on Non -Subject Urban Streams 3 1 Preservation Site on Subject Urban Streams 3 1 Preservation Site on Non -Subject Rural Streams 5 1 Preservation Site on Subject Rural Streams 10 1 (n) RIPARIAN BUFFER RESTORATION SITE OR ENHANCEMENT SITE. Authority staff shall make an on- site determination as to whether a potential mitigation site qualifies as a restoration site or enhancement site as defined in Paragraph (b) of this Rule. Riparian buffer restoration sites or enhancement sites shall meet the following requirements: (1) Buffer restoration sites or enhancement sites may be proposed as follows: Buffer width (ft) Proposed Percentage of Full Credit Less than 20 0% 20-29 75% 30-100 100% 101-200 33% (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: (1) Retroactive Credit.

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 c375 8 f-5 e27-46cf-823 7- 47f890d9329a&groupld=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 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.
