Re: Site Viability for Buffer Mitigation & Nutrient Offset — Wingfoot Site
Located off Moye Turnage Rd, Farmville, NC
Neuse River Basin/HUC 03020203
Pitt County
Dear Mr. Yates,
On August 30, 2018, Katie Merritt, with the Division of Water Resources (DWR), assisted you and
others from Clearwater Mitigation Solutions, LLC (CMS) at the proposed Wingfoot Mitigation Site
(Site) in Farmville, NC. Staff with the Division of Mitigation Services (DMS) were also present
onsite. The Site is in the Neuse River Basin. The Site is being proposed as part of a full -delivery
buffer mitigation project for the DMS (RFP # 16-007402). At your request, Ms. Merritt performed
an onsite assessment of riparian land uses adjacent to surface waters onsite, which are shown on the
attached map labeled "Figure 8B".
Ms. Merritt's evaluation of the features onsite and their associated mitigation determination for the
riparian areas are provided in the table below. This evaluation was made from Top of Bank (TOB)
and landward 200' from each feature for buffer mitigation pursuant to 15A NCAC 02B .0295
(effective November 1, 2015) and for nutrient offset credits pursuant to 15A NCAC 02B .0240.

The map that is attached (Figure 8B) was prepared by CMS for DMS and accurately represents the
mitigation type determinations of each feature labeled in the table above. This map was initialed by
Ms. Merritt on September 25, 2018. This letter should be provided in all stream and wetland,
buffer and/or nutrient offset mitigation plans for this Site.
This letter does not constitute an approval of this site to generate mitigation credits. Pursuant to 15A
NCAC 02B .0295, a mitigation proposal and a mitigation plan shall be submitted to DVWR for written
approval prior to conducting any mitigation activities in riparian areas and/or surface waters for
buffer mitigation credit. Pursuant to 15A NCAC 02B .0240, a proposal regarding a proposed nutrient
load -reducing measure for nutrient offset credit shall be submitted to DWR for approval prior to any
mitigation activities in riparian areas and/or surface waters.
All vegetative plantings, performance criteria and other mitigation requirements for riparian
restoration, enhancement and preservation must follow the requirements in 15A NCAC 02B .0295 to
be eligible for buffer and/or nutrient offset mitigation credits. For any areas depicted as not being
viable for nutrient offset credit above, one could propose a different measure, along with supporting
calculations and sufficient detail to support estimates of load reduction, for review by the DWR to
determine viability for nutrient offset in accordance with 15A NCAC 02B .0240.
This viability assessment will expire on September 26, 2020 or upon the submittal of an As -
Built Report to the DWR, whichever comes first. This letter should be provided in all stream,
wetland or buffer mitigation plans for this Site.
Please contact Katie Merritt at [phone] if you have any questions regarding this
correspondence.
Sincerely,
KAH/km
