REGAN Secretary LINDA CULPEPPER Director NORTH CAROUNA Environmental Quality November 22, 2019 Brad Breslow Resource Environmental Solutions, LLC 302 Jefferson Street, Suite 110 Raleigh, NC 27605 (via electronic mail: bbreslow(a,res.us ) DWR ID# 2019-0846 Wake County Re: Site Viability for Buffer Mitigation & Nutrient Offset — Cairo Site Located near 6300 Johnston Pond Rd, Fuquay-Varina, NC Neuse 03020201 Dear Mr. Breslow, On August 12, 2019, Katie Merritt, with the Division of Water Resources (DWR), received a request from you on behalf of Resource Environmental Solutions, LLC (RES) for a site visit near the above - referenced site in the Neuse River Basin within the 8-digit Hydrologic Unit Code 03020201. The site visit was to determine the potential for riparian buffer mitigation and nutrient offset within a proposed site boundary, which is more accurately shown in the attached map labeled "Figure 3". Portions of this site are intended to be proposed to the IRT as a stream and wetland mitigation site by RES. On September 10, 2019, Ms. Merritt performed a site assessment of the subject site. Staff with RES were also present. One stream within the proposed site boundary and labeled UT6, was not assessed and does not have a stream/buffer determination on file. 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 existing 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.

'Subjectivity calls for the teatures were determined by DWR in correspondence dated October 3, 2016 and September 23, 2019, using the 1:24,000 scale quadrangle topographic map prepared by USGS and the most recent printed version of the soil survey map prepared by the NRCS . 2 NC Division of Water Resources - Methodology and Calculatio for determining Nutrient Reductions associated with Riparian Buffer Establishment. Nutrient offset credit cannot be generated adjacent to coastal headwater stream restoration sites 3The area of preservation credit within a buffer mitigation site shall comprise of no more than 25 percent (25%) of the total area of buffer mitigation per 15A NCAC 0295 (o)(5) and 15A NCAC 0295 (o)(4). Site cannot be a Preservation Only site to comply with this rule. Maps that are attached to this letter were prepared by RES and were initialed by Ms. Merritt on November 22, 2019. 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 DWR 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 November 22, 2021 or upon the submittal of an As -Built Report to the DWR, whichever comes first. This letter should be provided in any nutrient offset, buffer, stream or wetland mitigation plans for this Site. Please contact Katie Merritt at (919) 707- 3637 if you have any questions regarding this correspondence.
