You may recall the City of Durham (City) Department of Water Management (DWM) owns and maintains the New Hope Creek Interceptor (NHCI), a 48 inch gravity sewer main that is located on U.S. Army Corps of Engineers (USACE) land in the Jordan Lake watershed. The existing NHCI was constructed circa 1981 prior to Jordan Lake's completion in 1983. The NHCI is 36 years old and approximately 3,450 feet in length. The City's Emergency Action Plan proposes a parallel sewer main be installed within the same easement. The proposed main would provide 100% system redundancy so the City's wastewater can be easily diverted to the parallel interceptor system should problems with or a failure of the existing interceptor crossing develop, in addition to providing a means for performing normal operation and maintenance services which currently do not appear to be viable due to location and access restrictions. Failure of the existing 48 -inch NHCI during normal operations, could discharge 80% of the SDWRF's average daily flow of 20 MGD, or approximately 16 MGD, into the adjacent New Hope Creek for the time required to install, setup, and operate a bypass pumping system, which is estimated to take between 5 and 7 days, discharging an estimated 80 to 112 million gallons of raw sewage into the Cape Fear River Basin. Failure of the NHCI during peak flow periods, could discharge 80% of the SDWRF's permitted daily flow of 75 MGD, or approximately 300 to 420 million gallons of raw sewage into the Cape Fear River Basin. Trees will not be cut as the proposed main is within the existing maintained easement. Threatened or endangered species will not be affected and construction impacts will be temporary. The project will not affect the above land uses. There is a proposed comminutor junction box inside the buffer of an unnamed intermittent tributary at the south end of the project. Ms Jennifer Burdette approved the box via phone on 11-30-17 as it is a necessary in-line feature associated with the sewer line. EAP PCN RESPONSE TO COMMENT3S` N Thank you for your consideration in this matter. Please let me know if you have any questions or need additional information. As previously discussed this project is under extraordinary circumstances due to the sites use as a water fowl impoundment that is intentionally flooded every other year. We again respectfully request this review be expedited as much as possible in order to finish construction before the waterfowl impoundment is flooded again. If there is anything we can do to help expedite the review please let us know. Respectfully submitted: FALCON ENGINEERING, INC. Christopher . urkhardt Environmental Services Manager CC: Ms. Jennifer Burdette NC DWR Buffer Coordinator Attachments: Durham EAP PCN Response to Comments THE CITY OF DURHAM C/O K. F. CARTER ENGINEERING COMPANY/ EMERGENCY ACTION PLAN/ E16017/12.1.2017 EAP PCN RESPONSE TO COMMENTS 3 Durham New Hope Creek Interceptor PCN Response to Comments 1) Section B.3d: The information in the section appears to have been cutoff and I only have a section of the first sentence. Please provide the complete explanation for the purpose of the proposed project. ➢ The purpose of the proposed sewer main is to allow sewage to be diverted from the existing main in the event of failure as well as a means for normal routine inspections, condition assessment, operation and maintenance, cleaning and to provide the City of Durham with 100% system redundancy. 2) Section C.3: There are only 3 impact sites listed in the Stream Impacts table. However, there are four stream impact locations in the 54 -inch New Hope Creek Parallel Interceptor Plans/Permit Impact Drawings. It looks like the temporary impacts for "Stream 4" as shown on the plans are not included in the PCN document. If the plan is to avoid the impact at Stream 4, then remove the impact it from the permit impact drawings, but if it is indeed being impacted it needs to be included in the table found at section C.3 of the PCN. Also, instead of square footage of stream, show the linear footage of the stream to be impacted plus the average width of the feature at that location. ➢ There are no proposed impacts to Stream 4, revised plans with linear footage of the stream to be impacted plus the average width of the feature at that location are attached. 3) Section C.3: All of the stream impacts are listed as temporary, but it appears that each of the streams are being lined with riprap over the proposed pipe. Unless the plan is to remove the riprap and restore the stream to pre-existing contours and conditions, this would be considered a permanent impact and should be accounted for as such. It is good that you have a note indicating that the riprap "shall be 'keyed -in' (placed level with stream bottom) so the outer face of the riprap is flush with the existing grade after installation." So, just revise the permit impact drawings and PCN to account for the permanent impacts associated with the riprap installation. ➢ Permit impact drawings and PCN have been revised to account for the permanent impacts associated with the riprap installation. 4) Please confirm that, in wetlands, the top 6 to 12 inches of the trench will be backfilled with topsoil from the trench, as required in the Nationwide Permit 12 description. It may be a good idea to add a note about this to the plans. If there is a reason why this can't be done, please explain. The top 6 to 12 inches of the trench will be backfilled with topsoil from the trench. A note has been added to the plans. 5) According to the Additional Regional Condition for NWP #12 (4.1.9), A plan to restore and re -vegetate wetland areas cleared for construction must be submitted with the required PCN. Cleared wedand areas shall be re -vegetated to the maximum extent practicable with native species of canopy, shrub, and herbaceous species. Fescue grass shall not be used. I did not see a planting plan in the information that I received. Could you please provide one or let me know if I am missing something? ➢ Cleared wetland areas will be re -vegetated to the maximum extent practicable with native herbaceous species. Fescue grass shall not be used. A note has been added to the plans. 6) Preliminary Jurisdictional Determination Form Attachment A: Please fill out the Aquatic Resources table.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The existing easement was constructed prior to Jordan lake and the water fowl impoundment. The area is surrounded by wetlands. The existing easement was chosen for the parallel sewer main due to the proximity of the existing main and to avoid additional impacts to the surrounding wetlands by creating a new easement. The sewer main is confined by 1-40 and the convergence of the existing 42 -Inch New Hope Creek Gravity Sewer and the existing 42 -Inch Third Fork Creek Gravity Sewer. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Proposed construction techniques to avoid or minimize impacts include; erosion control measures, orange barrier fencing, sift fence and wood matting, as well as anti -seep collars for stream and wetlands crossings. NCDENR Division of Land Quality will review the erosion control plans and provided comment. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.
