Hanes Mill Road, Suite 300 Winston Salem, NC 27105 Subject: DWR# 20190921 Compliance Inspection Line 2 Exposure Friendship Road Davidson County, North Carolina Corblu Project No. 02-041901 Dear Ms. Homewood, VIA EMAIL Corblu conducted the compliance inspection for Colonial Pipeline Company (CPC), Line 2 Exposure (DWR# 20190921) natural stream design (NSD) project located in Davidson County, North Carolina. Based on the attached NCDWQ 401 Water Quality Certification approval the NSD was permitted for a total of 62 linear feet (LF) [42 LF of permanent and 20 LF of temporary impacts (workspace/dam and pump)] to address the exposure within the unnamed intermittent tributary to Abbots Creek. The stream and site appear to be stabilized and erosion control measures are in place. During construction CPC and their contractors made an on -site call to stabilize additional linear footage of stream channel based on substrate conditions. Specifically, CPC mixed rock with the existing substrate (composed mainly of sandy clay with minimal gravel) to provide a more stable stream substrate which resulted in an additional 50 linear feet (LF) of stream disturbance. Further, the associated stream banks were sloped back to achieve a more stable bank slope ratio. The existing failing culvert was removed and replaced. Approximately 25 LF of riprap was embedded, upstream of the culvert, for channel for stability. Based on our measurements a total of 75 LF of additional stream impacts were observed at the above referenced project location. 770-591-9990 r3225uth Cherokee Lane, Bldg. 800, Woodstock, GA 30188 corblu.com Compliance Inspection Colonial Pipeline Company — Line 2 Exposure October 30, 2019 Corblu Project No. 02-041901 We are reaching out for guidance from DWR on how to proceed based on the additional impacts.
