Sullins Director October 19, 2010 MEMORANDUM To: Brad Wall, NCDOT Division 7 Maintenance Engineer From: Amy Euliss, NC Division of Water Quality, Office Dee Freeman Secretary Subject: Scoping comments on proposed replacement of Bridge nos. 32 (SR1582), 66 (SR 1910), and 134 (SR 2356) in Alamance County, Bridge no 47 (SR 1301) in Caswell County, Bridge no. 231 (SR 1005) in Guilford County, Bridge nos. 47 (SR 1520), 76 (SR 1113), and 135 (SR 1516) in Orange County, and Bridge nos. 44 (SR 2336), 86 (SR 2598), and 143 (SR 1321) in Rockingham County. Reference your correspondence dated September 17, 2010 in which you requested comments for the referenced projects. The NCDWQ offers the following comments. Project Specific Comments: Bridge No 32 (SR 1582) over Buttermilk Creek in Alamance County *Potential impacts to Buttermilk Creek 1. Buttermilk Creek are WSII, HQW; NSW waters of the State. NCDWQ is very concerned with sediment and erosion impacts that could result from this project. NCD WQ recommends that highly protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to Buttermilk Creek. NCD WQ requests that road design plans provide treatment of the storm water runoff through best management practices as detailed in the most recent version of NCDWQ's Stormwater Best Management Practices. 2. Review of the project reveals the presence of surface waters classified as WSII; High Quality Waters of the State in the project study area. This is one of the highest classifications for water quality. Pursuant to 15A NCAC 2H.1006 and 15A NCAC 2B .0224, NCDOT will be required to obtain a State Stormwater Permit prior to construction except in North Carolina's twenty coastal counties. 3. This project is within the Jordan Lake Basin. Riparian buffer impacts shall be avoided and minimized to the greatest extent possible pursuant to 15A NCAC 2B .0267. Bridge No 66 (SR 1910) over Quaker Creek in Alamance County - d - .- ,_ *Potential impacts to Quaker Creek 4. Quaker Creek are WSII, HOW; NSW waters of the State. NCDWQ is very concerned with sediment and erosion impacts that could result from this project. NCDWQ recommends that highly protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to Quaker Creek. NCDWQ requests that road design plans provide treatment of the storm water runoff through best management practices as detailed in the most recent version of NCDWQ's Stormwater Best Management Practices.

New Hope Creek are WSV; NSW waters of the State. NCDWQ is very concerned with sediment and erosion impacts that could result from this project. NCDWQ recommends that highly protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to New Hope Creek Creek. NCDWQ requests that road design plans provide treatment of the storm water runoff through best management practices as detailed in the most recent version of NCDWQ's Stormwater Best Management Practices. 15. This project is within the Jordan Lake Basin. Riparian buffer impacts shall be avoided and minimized to the greatest extent possible pursuant to 15A NCAC 2B .0267. Bridge No. 135 (SR 1516) over North Fork Little River in Orange County *Potential impacts to North Fork Little River and an Unnamed Tributary to North Fork Little River. 16. North Fork Little River are WSII; NSW waters of the State. NCDWQ is very concerned with sediment and erosion impacts that could result from this project. NCDWQ recommends that highly protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to North Fork Little River Creek. NCDWQ requests that road design plans provide treatment of the storm water runoff through best management practices as detailed in the most recent version of NCDWQ's Stormwater Best Management Practices. 17. Review of the project reveals the presence of surface waters classified as WSII; High Quality Waters of the State in the project study area. This is one of the highest classifications for water quality. Pursuant to 15A NCAC 2H .1006 and 15A NCAC 2B .0224, NCDOT will be required to obtain a State Stormwater Permit prior to construction except in North Carolina's twenty coastal counties. 18. This project is within the Neuse River Basin. Riparian buffer impacts shall be avoided and minimized to the greatest extent possible pursuant to 15A NCAC 2B .0233. Please note that both North Fork Little River and the Unnamed Tributary to North Fork Little River are on the Soil Survey map and thus subject to the Neuse River Buffer rules. Bridge No. 44 (SR 2336) over Jacob's Creek in Rockinnham.County _ *Potential impacts to Jacob's Creek and an Unnamed Tributary to Jacob's creek. 19. During field discussions, NCDWQ agreed to allow vertical endbents at this site, due to the parallel impacts possible to both Jacob's Creek and the Unnamed Tributary to Jacob's creek, if deemed necessary. Bridge No.86 (SR2598) over Little Troublesome Creek in Rockingham County *Potential impacts to Little Troublesome Creek and adjacent wetlands 20. Little Troublesome Creek are WSV; NSW waters of the State. NCDWQ is very concerned with sediment and erosion impacts that could result from this project. NCDWQ recommends that highly protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to Little Troublesome Creek Creek. NCDWQ requests that road design plans provide treatment of the storm water runoff through best management practices as detailed in the most recent version of NCDWQ's Stormwater Best Management Practices. 21. This project is within the Jordan Lake Basin. Riparian buffer impacts shall be avoided and minimized to the greatest extenrpossible pursuant to 15A NCAC 2B .0267. 22. Previous communications with NCDWQ stated that this section was 303D. However, the 303D section of Little Troublesome Creek is upstream of the project. Bridge No. 143 (SR 1321) over Beaver Island Creek in Rockingham County *Potential impacts to Beaver Island Creek. No project specific comments. mechanized equipment and leaving the stumps and root mat intact allows the area to re-vegetate naturally and minimizes soil disturbance. 11. If foundation test borings are necessary; it should be noted in the document. Geotechnical work is approved under General 401 Certification Number 3624/Nationwide Permit No. 6 for Survey Activities. 12. Sediment and erosion control measures sufficient to protect water resources must be implemented and maintained in accordance with the most recent version of North Carolina Sediment and Erosion Control Planning and Design Manual and the most recent version of NCS000250. 13. All work in or adjacent to stream waters shall be conducted in a dry work area unless otherwise approved by NCDWQ. Approved BMP measures from the most current version ofNCDOT Construction and Maintenance Activities manual such as sandbags, rock berms, cofferdams and other diversion structures should be used to prevent excavation in flowing water. 14. Sediment and erosion control measures shall not be placed in wetlands and streams. 15. Borrow/waste areas shall avoid wetlands to the maximum extent practical. Impacts to wetlands in borrow/waste areas could precipitate compensatory mitigation. 16. Heavy equipment shall be operated from the bank rather than in stream channels in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into streams. This equipment shall be inspected daily and maintained to prevent contamination of surface waters from leaking fuels, lubricants, hydraulic fluids, or other toxic materials. 17. Riprap shall.not be placed in the active.thalweg channel or placed in the streambed in a manner that precludes aquatic life passage. Bioengineering boulders or structures should be properly designed, sized and installed. Thank you for requesting our input at this time. NCDOT is reminded that issuance of a 401 Water Quality Certification requires that appropriate measures be instituted to ensure that water quality standards are met and designated uses are not degraded or lost.
