Re: Neuse Riparian Buffer Umbrella Mitigation Bank
Jones, Johnson, and Wayne Counties, North Carolina
Dear Ms. Chapman and Mr. Kulz:
Please find the attached Addendum to the EBX Neuse Riparian Buffer Umbrella
Mitigation Bank Prospectus and revised RBMBI. Note that in addition to the
inclusion of nutrient offset credit in the instrument, we have amended the credit
yield for the riparian buffer mitigation as well. The changes to the riparian buffer
mitigation are the result of update information regarding the easement boundary
locations. This resulted in a decrease of projected yield from the Marston Site
and an increase at the Nahunta Site. The increase at the Nahunta site is the result
of the fact that less stream was backfilled than originally indicated. Therefore, the
amount of existing wooded riparian buffer was over-estimated at the site. The
updated riparian buffer credit yield reflects the fact that the over-estimated
existing wooded riparian buffer amount is, now, not subtracted from the total
yield from the Nahunta Site.
If there is any additional information you need or any way we can assist in
expediting the processing of this application, please do not hesitate to contact me
at [phone].
Very truly yours,
KIMLEY-HORN AND ASSOCIATES, INC.

AGREEMENT TO ESTABLISH THE EBX NEUSE RIPARIAN BUFFER UMBRELLA
MITIGATION BANK
IN JOHNSTON, WAYNE, AND JONES COUNTIES, NORTH CAROLINA
This EBX Neuse Riparian Buffer Umbrella Mitigation Banking Instrument (RBMBI) is made
and entered into on the day of , 200_, by EBX Neuse I, LLC, hereinafter
Sponsor, and the North Carolina Division of Water Quality (NCDWQ).
WHEREAS the purpose of this Agreement is to establish the EBX Neuse Riparian Buffer
Umbrella Mitigation Bank (Bank) providing compensatory mitigation for unavoidable riparian
buffer impacts and/or nutrient offsets separately authorized by Authorizations or Variances to
impact Riparian Buffers and/or stormwater management requirements per 15A NCAC 2B .0200;
WHEREAS the Sponsor currently controls through the purchase and recording of a
permanent conservation easement, certain parcels of land as described in the Neu-Con Wetland
and Stream Umbrella Mitigation Banking Instrument ( Neu-Con MBI), the RBMBI Prospectus
with Addendum, and in the Neu-Con Wetland and Stream Umbrella Mitigation Bank Restoration
Plans (Restoration Plans) that are located in the Neuse Basin in Johnston, Wayne, and Jones
Counties, North Carolina (Appendix A), and as shown in Figures I through 4 of the RBMBI
Prospectus and Addendum;
WHEREAS NCDWQ agrees that the Bank site is a suitable riparian buffer mitigation bank
site, and that implementation of the plans as described in the Restoration Plans is likely to result
in restored and protected riparian buffers at the Bank site;
WHERAS the Sponsor may acquire additional buffer mitigation sites in the Neuse River Basin
and submit each such site to NCDWQ for review and approval for inclusion in the Bank;
THEREFORE, it is mutually agreed between the parties to this Agreement that the following
provisions are adopted and will be implemented upon execution of this RBMBI.
General Provisions
1. The goal of the Bank is to restore, enhance, and preserve stream systems with the adjacent
riparian buffers and their functions and values to compensate in appropriate circumstances for
unavoidable stream buffer impacts and nutrient reduction requirements authorized by 15A
NCAC 2B .0233, 2B .0234, and 213 .0235 in circumstances deemed appropriate by NCDWQ.
2. Use of credits from the Bank to offset riparian buffer impacts and nutrient reduction
offsets authorized by 15A NCAC 213 .0233, 2B .0234, and 2B .0235. Approvals must be in
compliance with said Rules.
(Revised Version 2.0 October, 2008)
3. NCDWQ shall make final decisions concerning the amount and type of compensatory
mitigation or nutrient offset to be required for authorized purposes, and whether or not the use of
credits from the Bank is appropriate to offset those purposes.
4. The initial Bank sites have previously been restored and are protected by permanent
conservation easements. A more detailed description of the baseline conditions of the initial
sites is contained in the Monitoring Plans in Appendix A.
5. A Restoration Plan for each proposed additional site shall be submitted to NCDWQ for
review and approval prior to each such additional site being included in the Bank, and such
submittals shall include a site-specific Monitoring Plan.
6. The Sponsor shall perform the work described in each site specific Monitoring Plan until
success criteria have been met.
7. The Sponsor shall monitor the Bank sites as described in the Monitoring (or Restoration)
Plans, until such time as the NCDWQ determines that the success criteria of a density of 320
trees per acre after five years have been met. The monitoring period shall be a minimum of five
years.
8. The Sponsor is responsible for assuring the success of the restoration, enhancement and
preservation activities at the Bank site, and for the overall operation and management of the
Bank.
9. The Sponsor shall provide to NCDWQ the annual reports as described in the RBMBI
Prospectus and Addendum (Appendix A). The Sponsor shall also copy NCDWQ on
correspondence that documents the sales of credits to applicants.
10. NCDWQ shall review said annual reports, and may, at any time, after consultation with
the Sponsor, request the Sponsor to take remedial action at a Bank site designed to achieve the
specified success criteria.
11. The Sponsor shall implement any remedial measures necessary to achieve the specified
success criteria. In the event the Sponsor determines that remedial action may be necessary, it
shall provide notice of such proposed remedial action to NCDWQ. No remedial actions shall be
taken without the concurrence of NCDWQ.
12. NCDWQ shall be allowed reasonable access to the Bank sites for the purposes of
inspection of the Sites and compliance monitoring activities. The Sponsor shall be notified 48
hours in advance of any such NCDWQ inspection.
(Revised Version 2.0 October, 2008)
Use of Mitigation Credits
13. The Geographical Service Area (GSA) is the designated area wherein a bank can
reasonably be expected to provide appropriate compensation for riparian buffer impacts or
nutrient offset payments. The GSA for this Bank shall include the Neuse River Basin
Hydrologic Units 03020201 for the Westbrook Site, 03020203 for the Nahunta Site, and
03020204 for the Marston Site. Additionally, other Sites, if approved by NCDWQ, in different
8-Digit Hydrologic Units may be added in the future. Credits generated from such Sites will
apply within the 8-Digit Hydrologic Units in which the Sites are located. Use of credits from the
Bank to compensate for impacts beyond the GSA may be considered by NCDWQ at an out-of-
HUC multiplier of 1.5 on the mitigation or nutrient reduction credits. Separate ledgers shall be
developed and maintained for each Site to track mitigation or nutrient reduction credits.
14. The buffer mitigation credits generated by the initial Bank sites shall be as specified in
Table 1, below. The nutrient reduction credits are summarized in Table 2, below.
TABLE 1- Buffer Mitigation Credits
Zone 1 (sq ft) Zone 2 (sq ft) Total (sq ft) Total (acres)
Nahunta 428,000 250,000 678,000 15.5
Marston 211,000 114,000 325,000 7.4
Westbrook 226,000 131,000 357,000 8.2

Nahunta 33.6 76,000
Marston 32.4 74,000
Westbrook 19.5 44,000
Total 85.5 194,000
15. It is anticipated by the parties to this Agreement that use of riparian buffer mitigation
credits shall be "in-kind;" that is, that riparian buffer credits will be used to offset riparian buffer
impacts. For nutrient reduction credits, the Sponsor and NCDWQ agree that the pounds of
nitrogen offset per acre of restored riparian buffer shall be 2,273 pounds per acre as established
by NCDWQ and applied to existing riparian buffer-based nitrogen abatement sites across the
State of North Carolina.
16. Riparian Buffer Mitigation Credits- Riparian buffer mitigation requirements and riparian
buffer mitigation credits will be determined according to the procedures described in 15A NCAC
(Revised Version 2.0 October, 2008)
2B 0.233 and .0242. Buffer restoration and buffer enhancement shall be defined per the
Memorandum titled "NCDWQ Buffer Interpretation/Clarification #2008-17, January 25, 2008"
17. Nutrient Reduction Credits - Nutrient offset payment requirements and nutrient
reduction credits will be determined according to the procedures described in 15A NCAC 2B
.0234, 2B .0235, and 2B .0240 provided such use has met all applicable requirements and is
authorized by the appropriate authority.
18. Notwithstanding the above, all decisions concerning the appropriateness of using credits
from the Bank to offset impacts to riparian buffers or offset nutrient reduction shall be made by
NCDWQ or NCDWQ's designee. Any necessary notice to and consultation with NCDWQ or
NCDWQ's designee for use of credits shall be through the riparian buffer impact or appropriate
stormwater review process.
19. Twenty percent (20%) of the riparian buffer mitigation credits and nutrient reduction
credits for each Bank site shall be available for sale immediately upon completion of all of the
following:
a. Execution of this RBMBI by the Sponsor and NCDWQ;
b. Approval of the Restoration and Monitoring Plans by NCDWQ;
c. Delivery to NCDWQ of the financial assurance described in paragraph 24 of this
RBMBI;
d. Recordation of the preservation mechanism described in paragraph 23 of this RBMBI;
20. The Sponsor must complete the initial physical and biological improvements to each
Bank site pursuant to the Restoration Plans no later than the first full growing season following
initial debiting of the Bank. The Sponsor shall provide a record drawing or as-built survey to
provide a record of the amount and nature of buffer restoration and enhancement completed.
21. Subject to the Sponsor's continued satisfactory completion of all required success criteria
and monitoring, additional buffer mitigation credits shall be available for sale by the Sponsor in
accordance with the schedule specified in Table 2, below:

22. Monitoring of the riparian buffer restoration and enhancement shall be based on the
CVS-EEP Protocol for Recording Vegetation Level 1-2 Plot Sampling Only Version 4.0, as
indicated in the Restoration and/or Monitoring Plans based on a success criteria of 320 trees per
acre after five years.
23. The Sponsor shall submit separate, annual ledgers for each Site documenting riparian
buffer credit releases and debits and the nutrient reduction credit releases and debits to NCDWQ
for maintaining accurate records of credit transactions made from each Site of the Bank. The
ledgers will reflect the amounts of riparian buffer mitigation credits and, separately, the nutrient
reduction credits. The buffer mitigation areas generally comprise the restored buffer Zones 1 and
2 adjacent to the various streams. The nutrient reduction credit areas generally comprise the
restored riparian buffer areas that are adjacent to streams from the outside edge of Zone 2 to 200
feet from the stream bank but within the easement boundaries. The nutrient reduction credit areas
also generally comprise restored buffers along ditches from the top of bank to 200 feet but within
the easement boundaries. The credit areas shall not overlap. Credits can be converted and
transferred from buffer mitigation to nutrient reduction credits, but the opposite shall not occur.
Accounting procedures shall include the generation of a report by the Sponsor showing credits
used each time they are debited from the Bank, which the Sponsor shall provide within 30 days
of the debit to NCDWQ. In addition, the Sponsor shall prepare an annual report, by the end of
(Revised Version 2.0 October, 2008)
each calendar-year, showing all credits used, and the balance of credits remaining to NCDWQ,
until such time as all of the credits have been utilized, or this Agreement is otherwise terminated.
All reports shall identify credits debited and remaining by type of credit (e. g. riparian buffer),
and shall include for each reported debit the NCDWQ ID number for the Authorization for
which the credits were utilized.
Property Disposition
24. The Sponsor has recorded a Permanent Conservation Easement for each initial Bank site
in the County where each site is located. The Sponsor shall record similar easements for each
additional site approved for inclusion in the Bank.
Financial Assurances
25. The Sponsor will provide to NCDWQ financial assurances for the pre-construction
release of credits in the form of performance bonds or letters of credit. Such financial assurances
shall be in the amount of twenty percent (20%) of the credits anticipated to be generated for each
site multiplied by the NCEEP price for riparian buffer mitigation in the Neuse River Basin. Such
financial assurances shall be retired upon submittal of the as-built report for each site. For the
initial Sites of the Bank (Marston, Westbrook, and Nahunta), no financial assurances are required
as the Sites have completed or are in the monitoring period.
Miscellaneous
26. Any delay or failure of Sponsor shall not constitute a default hereunder if and to the
extent that such delay or failure is primarily caused by any act, event or conditions beyond the
Sponsor's reasonable control and significantly adversely affects its ability to perform its
obligations hereunder including: (i) acts of God, lightning, earthquake, fire, landslide, drought,
hurricane, storm, flood, or interference by third parties; (ii) condemnation or other taking by any
governmental body; (iii) change in applicable law, regulation, rule, ordinance or permit
condition, or the interpretation or enforcement thereof, (iv) any order, judgment, action or
determination of any federal, state or local court, administrative agency or government body; or
(v) the suspension or interruption of any permit, license, consent, authorization or approval. If
the performance of the Sponsor is affected by any such event, Sponsor shall give written notice
thereof to the NCDWQ as soon as is reasonably practicable. If such event occurs before the final
availability of all credits for sale, the Sponsor shall take remedial action to restore the property to
its condition prior to such event, in a manner sufficient to provide adequate mitigation to cover
credits that were sold prior to such delay. Such remedial action shall be taken by the Sponsor
only to the extent necessary and appropriate, as determined by NCDWQ.
27. No third party shall be deemed a beneficiary hereof or shall be entitled to seek
enforcement hereof.

1.0 Introduction
EBX NEUSE I, LLC (Sponsor) has determined that, in addition to riparian buffer mitigation
credit, the Neu-Con Wetland and Stream Umbrella Mitigation Bank in Johnston, Wayne and
Jones Counties, North Carolina has potential nutrient reduction credit assets available based on
certain restored buffers that were not included as riparian buffer mitigation assets. These buffers
may extend from the outside edge of Zone 2 (50 feet from the stream bank) out to as much as
200 feet from the restored stream banks and from the bank out to 200 feet along ditches and
streams that were not restored (See Figures 1 through 4). Therefore, the Sponsor is submitting
this addendum to the Prospectus dated September 2008 for the EBX Neuse Riparian Buffer
Umbrella Mitigation Bank (Bank) as well as a Revised Riparian Buffer Mitigation Banking
Instrument (Revised RBMBI Version 2.0) for approval by the North Carolina Division of Water
Quality (NCDWQ).
The rules for providing nutrient reduction credits in the Neuse basin are found in 15A NCAC 2B
.0240 (Nutrient Offset Payments). This document proposes to establish a method for
establishing, accounting for, and debiting nutrient reduction credits at the Bank.
2.0 Riparian Buffer Restoration and Available Credit
For the purposes of this document, buffer restoration is defined as the planting of areas within
200 feet of the stream banks that contain less than 100, 5-inch DBH trees per acre at the densities
and species composition described in detail in the Monitoring Reports. The Zone 1 buffers have
been quantified by determining the area between the stream bank to a line 30 feet from the bank
and parallel to the bank as displayed in Figure 1. Zone 2 has been quantified by determining the
area between the 30 foot line described above and a line 50 feet from the bank and parallel to the
stream bank. The remaining buffers (50 to 200 feet or from the ditch bank to 200 feet), within the
easement boundary, are shown in Figures 1 through 4 as described above. The riparian buffer
mitigation credit areas are described in the Prospectus and the buffer mitigation credit areas and
nutrient reduction credits areas do not overlap. Table 1 below reflects the amount of buffer
restoration that will be used for nutrient reduction credit (and does not include the riparian buffer
mitigation credit areas described in the Prospectus).
In order to determine the amount of mitigation credit in terms of pounds of nitrogen, the amount
of 2,273 pounds per acre as established by NCDWQ and as applied to existing riparian buffer-
based nitrogen abatement sites across the State of North Carolina shall be used.

Nahunta 33.6 76,311
Marston 32.4 73,763
Westbrook 19.5 44,281
Total 85.5 194,355
The vegetation monitoring has established the current success status of the re-established buffers.
Both the Marston and Westbrook sites have met the success criteria of 320 trees per acres after
five years based on their fifth year of vegetation monitoring as required by 15A NCAC 2B .0240.
The Nahunta site is currently meeting the success criteria based on the third year monitoring
report. The most recent reports are contained in Appendix A of the Prospectus.
In addition to the Westbrook, Nahunta, and Marston sites, the Sponsor may submit to NCDWQ
additional Neuse buffer mitigation sites at a later date for approval and inclusion into the Bank.
3.0 Service Area
The service area requested for the nutrient reduction credit is the same as that for the riparian
buffer mitigation described in the RBMBI and Prospectus.
4.0 Credit Tracking and Credit Release Schedule
The credit release schedule and credit tracking are described in the Revised RBMBI Version 2.0
and the Prospectus. Figures 1 through 4 depict the location of the nutrient reduction buffer
restoration areas as they relate to each Site's easement boundaries, existing forest vegetation
prior to Site restoration (not included in the credit areas), and previously established riparian
buffer mitigation credit areas.
5.0 Success Criteria and Monitoring
The Success Criteria and Monitoring requirements are provided in Appendix A of the
Prospectus. It is assumed that the vegetation monitoring and success criteria applicable to the
Neu-Con Wetland and Stream Umbrella Mitigation Bank are acceptable for buffer mitigation
purposes. The Sponsor will submit a separate Buffer Monitoring Report to NCDWQ at the end
of each remaining monitoring year for the Nahunta Site and for each of the five vegetation
monitoring years for any future, additional Bank sites. The buffer mitigation will be considered
successful if, five years after the original planting date, there is an average of 320 tree species per
acre.
