This plan is necessary to evaluate avoidance and minimization measures and potential indirect impacts for the project. Attached 4 11x17 Plans. There will be no indirect impacts such as water and sewer as these are already available on site without any crossings.  Cumulative permanent stream impacts for this project exceed the 150 linear foot threshold per NWP 39 Regional Condition 3.2, and therefore compensatory mitigation is required. Please submit a compensatory mitigation plan. The mitigation rule generally prescribes purchasing stream credits first through a mitigation bank with stream credits available in this 8-digit HUC, or second through the NC Division of Mitigation Services; please provide a mitigation acceptance letter from your proposed compensatory mitigation provider. Typically, compensatory mitigation is required at a 2:1 credit to impact ratio unless otherwise justified based on evaluation of aquatic function. Attached is the NCSAM form for Stream A-2. We have assumed 1:1 credit to impact ratio. We have contacted EBX-EM, LLC (RES) Caitlan Parker and she indicated that they have the available credits. We are expecting an email confirmation soon which will be forwarded when received. And the following from NCDENR/DWQ  Please provide a copy of the stream/buffer determination that was confirmed with Durham County/City. This was included in the 71 page PCN package but is attached separately. Pre-Construction Notification - Request for Additional Information / SAW -2020-02005 / Oakridge / Durham County NCDENR 20201343, Version 1 2 Please contact Ben Wilson at (919) 697-5446 if you have any questions.
