The Division has determined that your application is incomplete and cannot be processed. The application is on-hold until all of the following information is received: 1. If the U.S. Army Corps of Engineers (USACE) requests a response to any comments received as a result of the Public Notice, please provide the Division with a copy of your response to the USACE. 2. In order to ensure that the project is appropriately authorized under state regulations please provide documentation that the Approved Jurisdictional Determination for the excluded streams and wetlands within the project is still valid. 3. In order to adequately assess DWR stream mitigation requirements for the proposed project, please provide DWR stream forms to support the determinations. 4. Pursuant to 15A NCAC 02H .01305(b) “In assessing whether the proposed activity will comply with water quality standards, the Division shall evaluate if the proposed activity: (1) has avoided and minimized impacts to surface water and wetlands….”. You have provided an Onsite Alternative Site Plan with a statement that the preferred alternative plan includes road crossings located on the stream features that separate upland area within the project boundaries and therefore impacts re necessary. This information does not adequately document that the proposed plan has avoided and minimized impacts to the maximum extent. Please provide more detailed information regarding the limited use of bridges within the proposed project and why further modifications within the project are not feasible to further reduce impacts (for example, shifting the roadway to avoid Crossing 12, relocating the future water tank so crossing #21 is not necessary, shifting crossing #6 to avoid wetland impacts, locating the road within the break in jurisdiction on Stream J).

The application states that a Stormwater Management Plan will be required by DWR and that a detailed stormwater management plan will be reviewed and approved by the City of Oxford. Please clarify this discrepancy. 6. Pursuant to 15A NCAC 02H.0506(b) “a 401 Water Quality Certification may only be issued upon determining that the proposed activity will comply with state water quality standards which includes designated uses, numeric criteria, narrative criteria and the state’s antidegradation policy, as defined in rules of 15A NCAC 02B .0200… In assessing whether the proposed activity will comply with water quality standards, the Division shall evaluate if the proposed activity: (2) would cause or contribute to a violation of water quality standards; (3) would result in secondary or cumulative impacts that cause or contribute to, or will cause or contribute to, a violation of water quality standards;” In order for the Division to fully evaluate potential hydrological impacts on some stream and wetland features within the project limits, please provide the location of all outlet structures from the SCMs shown on the proposed plan sheet. In order to avoid further requests for additional information upon receipt of the response to this item, the Division strongly encourages that you carefully evaluate the proposed site plan for locations where existing surface hydrology will be redirected and would therefore have the potential to remove or reduce the existing functions of a stream and/or wetland. Based on the current proposed plan the Division believes there is potential for indirect impacts to some features within the overall project limits. 7. The outlet alignment of the culvert at Crossing #1 appears to be at an extreme angle with the natural channel. The Division has significant concerns about the proposed alignment causing the downstream streambank and channel to become unstable. Please realign the culvert or otherwise address this issue. 8. The culvert at Crossing #1 is proposed at a 7.22% slope, Crossing #5 is proposed at a 3.37% slope, and Crossing #8 is proposed at a 10.5% slope. The Division does not recommend culvert burial for such slopes greater than 2.5% slope. 9. The outlet alignment of the culvert at Crossing #5 appears to be at an extreme angle with the natural channel. The Division has significant concerns about the proposed alignment causing the downstream streambank and channel to become unstable. Please realign the culvert or otherwise address impacts this issue. 10. It appears that Crossing #5 and Crossing #21 will both disconnect a very small portion of the tributary above the crossing in such a way that it is likely to remove it’s existing uses/functions. This would constitute indirect impacts to this portion of stream for a loss of function. Please update the impact table to account for this length of stream as indirect impacts or modify the crossing location and plan sheets accordingly. 11. Stream X at Crossing #8 is proposed to be temporarily impacted. Please provide a restoration plan/profile showing how this channel will be restored upon construction completion. 12. Please provide stream and wetland restoration details for all temporary impact areas.

You have proposed that riprap aprons are to be considered permanent impacts but are proposed to not be considered a loss of stream function and therefore will not require mitigation. For all riprap aprons that are proposed to be significantly wider than the natural stream channel width, please provide additional restoration detail that indicate how the natural channel width and water depth will be maintained within the riprap pad and how natural stream function will be maintained. Pursuant to Title 15A NCAC 02H .0502(e) / 15A NCAC 02B .0611, the applicant shall furnish all of the above requested information for the proper consideration of the application. Please respond in writing within 30 calendar days of receipt of this letter by sending one (1) copy of all of the above requested information to the 401 & Buffer Permitting Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617 OR by submitting all of the above requested information through this link: https://edocs.deq.nc.gov/Forms/Supplemental-Information-Form (note the DWR# requested on the link is referenced above). If all of the requested information is not received within 30 calendar days of receipt of this letter, the Division will be unable to approve the application and it will be denied as incomplete. The denial of this project will necessitate reapplication to the Division for approval, including a complete application package and the appropriate fee.
