Spangler Environmental, Inc. (SEI) on behalf of Cimland, LLC, is submitting 5 copies of the
following requested information and response to comments from your letter dated July 23, 2008
for the above referenced project, located along Chandler Road, north of NC 98 in Durham, North
Carolina.
1. Please re-submit your site plans on full plan sheets at a scale of no smaller than 1" = 50' with
topographic contours.
• Please find 5 copies of the attached full size plans which have been approved by
Durham County. These plans were approved at a scale of 1 " = 60' and according to
a conversation with Ian McMillian of DWQ on August 21, 2008 the scale of these
plans will be considered sufficient.
2. Per the requirements of the Neuse River Riparian Buffer Rule, you must show that the site
meets diffuse flow requirements with a level spreader or other BMP per Chapter 8 of the
BMP Manual (see http://h2o/enr/state/nc/us/su/bmn forms.htm).
• Please refer to Sheet C410 of the attached plans for Storm Outlet Details. These
plans have been approved by Durham County and depict the use of 2 level spreaders
to meet diffuse flow requirements.
3. Please provide an inventory of imperviousness surfaces in each drainage area. The inventory
should include all purposed building footprints, roads, driveways, sidewalks, gravel-surfaces,
amenity areas, etc. A Stormwater Management Plan (SMP) must be provided for any
drainage areas that exceed 24 percent imperviousness. For each BMP, provide a complete

BMP Supplement Form with all the required items (see http://h2o/enr/state/nc/us/su/bmp
forms.htm). Per NCAC 213 15A: 02H.10000, a "drainage area" is defined as "the entire area
contributing surface runoff to a single point."
• Please refer to Sheet C.100 of the attached plans for Impervious Surface Area
Calculations. The total impervious area exceeds 24 percent and therefore we are
including the approved SMP and Approval letter from the City of Durham.
4. 360 square feet of compensatory buffer mitigation is required for this project. Please provide
a compensatory mitigation plan. The plan must conform to the requirements of 15A NCAC
2H .0500 and must be appropriate to the type of impacts proposed.
• Please find attached a copy of the acceptance letter for payment into the North
Carolina Ecosystem Enhancement Program (NCEEP) for mitigation to 360 square
feet of Neuse Buffer Impacts. The applicant proposes to pay the in-lieu fee for
compensatory mitigation to the buffer impacts.
If you have any questions, or require additional information, please contact me at 919-875-4288.

Durham, NC 27705 Expiration of Acceptance: January 17, 2009
Project: Greenway -Johnson Tract County: Durham
The purpose of this letter is to notify you that the North Carolina Ecosystem Enhancement Program (NCEEP) is willing to accept
payment for impacts associated with the above referenced project. Please note that this decision does not assure that the payment will
be approved by the permit issuing agencies as mitigation for project impacts. It is the responsibility of the applicant to contact these
agencies to determine if payment to the NCEEP will be approved.
This acceptance is valid for six months from the date of this letter and is not transferable. If we have not received a copy of the
issued 404 Permit/401 Certification/CAMA permit within this time frame, this acceptance will expire. It is the applicant's
responsibility to send copies of the permits to NCEEP. Once NCEEP receives a copy of the permit(s) an invoice will be issued based
on the required mitigation in that permit and payment must be made prior to conducting the authorized work. The amount of the In
Lieu Fee to be paid to NCEEP by an applicant is calculated based upon the Fee Schedule and policies listed at www.nceep.net.
Based on the information supplied by you the impacts that may require compensatory mitigation are summarized in the following
table.

Upon receipt of payment, EEP will take responsibility for providing the compensatory mitigation. If the regulatory agencies require
mitigation credits greater than indicated above, and the applicant wants NCEEP to be responsible for the additional mitigation, the
applicant will need to submit a mitigation request to NCEEP for approval prior to permit issuance. The mitigation will be performed
in accordance with the Memorandum of Understanding between the N. C. Department of Environment and Natural Resources and the
U. S. Army Corps of Engineers dated November 4, 1998.
