Mr. Ellison,
Attached is the approval letter for the Bear Basin mitigation project, along with all the comments that were generated
during the IRT's review of the project on the Mitigation Plan Review Portal,
*Please note that this approves the draft mitigation plan, but also identifies a major concern with the plan that must be
addressed in the Final Mitigation Plan,
When the permit application is submitted for Nationwide Permit #27 authorization, a copy of this letter should be included
along with a copy of the Final Mitigation Plan, Also, please ensure that the Final Mitigation Plan is posted to NCEEP's
documents portal so that all members of the IRT have access to the final plan.
Please let me know if you have any questions about the process or the attached letter,
Regards,
Tyler Crumbley

Re: NCIRT Review of Bear Basin Draft Mitigation Plan; NCEEP# 95362; SAW 2012 -01391
Mr. Michael Ellison
North Carolina Ecosystem Enhancement Program
1652 Mail Service Center
Raleigh, NC 27699 -1652
Dear Mr. Ellison:
The purpose of this letter is to provide the North Carolina Ecosystem Enhancement Program
(NCEEP) with all comments generated by the North Carolina Interagency Review Team (NCIRT)
during the 30 -day comment period for the Bear Basin Draft Mitigation Plan, which closed on 5 June,
2013. These comments are attached for your review. Additionally, this letter provides a brief account
of further review by the USACE, NCEEP, and the contracted provider, KCI Associates of North
Carolina, PC.
Based on our review of these comments, we have identified one major concern with the Draft Mitigation
Plan. This issue stems from the allowance of ditches adjacent to the project to remain open and the
credit generation of those areas affected by the ditch drainage. The USACE requested that those areas
subject to the permanent drainage be removed from credit generation as restoration, due to the known
drainage effect of the ditches. This issue was also present on another KCI project under portal review at
the same time (Twin Bays). Based on the concern, and comments provided by the USACE/NCIRT
during the portal review process (comments attached), KCI provided an email response and a request to
meet and discuss justification for the proposed credit generation on those affected areas for both
projects. Subsequently, a meeting was conducted on 27 June, 2013. The discussion included a review
of modeling results for pre -and post - construction ditch effect, lack of existing groundwater hydrologic
data, hydrologic inputs /exports of the sites, and potential for movement of ditches or ditch alterations.
It was agreed upon that a "non- credit generating" buffer be placed along all the ditches that are to
remain open. This buffer represents a zone of influence from the remaining ditches and will be at a
distance somewhere between the ditch edge and the previously modeled results of effective drainage (0'-
85' for Bear Basin) that will result in zero credit generation. There will be a secondary zone that may
result in generation of restoration credits. This zone will be determined by monitoring transects of wells
and the resulting data supporting the presumption that the work conducted will have a mitigating effect
on the influence of the remaining permanent ditches. Furthermore this area will be held to the stated
performance standard for hydroperiod in the Draft Mitigation Plan (8% of the growing season). Please
note that prior to finalizing the mitigation plan, we must approve the width of the zones discussed above.
The resolution of these issues must be included in the Final Mitigation Plan.
The Final Mitigation Plan is to be submitted with the Preconstruction Notification (PCN) Application
for Nationwide permit approval of the project along with a copy of this letter and a summation of the
addressed comments. If it is determined that the project does not require a Department of the Army
permit, you must still provide a copy of the Final Mitigation Plan, along with a copy of this letter, to the
appropriate USACE field office at least 30 days in advance of beginning construction of the project.
Please note that this approval does not preclude the inclusion of permit conditions in the permit
authorization for the project, particularly if issues mentioned above are not satisfactorily addressed.
Additionally, this letter provides initial approval for the Mitigation Plan, but this does not guarantee that
the project will generate the requested amount of mitigation credit. As you are aware, unforeseen issues
may arise during construction or monitoring of the project that may require maintenance or
reconstruction that may lead to reduced credit.
Thank you for your prompt attention to this matter, and if you have any questions regarding this
letter, please call us at 919- 846 -2564.
Sincerely,

MEMORANDUM FOR RECORD
SUBJECT: Bear Basin- NCIRT Comments During 30 -day Mitigation Plan Review
Purpose: The comments and responses listed below were posted to the NCEEP Mitigation Plan
Review Portal during the 30 -day comment period in accordance with Section 332.8(g) of the
2008 Mitigation Rule.
NCEEP Project Name: Bear Basin Restoration Site, Onslow County, NC
USACE AID #: SAW- 2012 -01391
NCEEP #: 95362
30 -Day Comment Deadline: 5 June, 2013
1. Eric Kulz, NCDWQ, 8 May, 2013:
• As per my comment on Twin Bays, the ditches that are to remain open along the
western and southern property boundaries will likely result in a reduction of wetland
credits from the site.
2. T. Crumbley and T. Tugwell, USACE, 4 June, 2013:
• Please review the indicator statuses of red maple, tulip poplar and water oak in section
7.1 Pg 19 of the plan. Insert "live, planted stems" at 210 /acre and remove the word
"mature" from the survivability discussion.
• Sec. 7.3, Proposed Conditions: Please remove the area directly adjacent to open ditch
(-85' based on modeling) from the acreage calculation at west and back of site. Move
paired wells back to the edge of potential wetland (i.e. 90' & 110' from ditch).
• Sec. 9.0 Vegetation Success, Criteria for meeting performance standards should also
include the terms "live, planted stems" criteria for success.
