Even though the loss was not substantial, it was estimated to be more than a five -gallon bucket which prompted an immediate site visit by Della Moore to begin supervising the sediment removal process utilizing the guidelines for sediment removal. Approximately 2 five -gallon buckets of sediment deposited in a stream (Old Field Creek) with approximately 3 five -gallon buckets of sediment deposited along the stream banks (see attached pictures). Once the site had been restored (see pictures), efforts were concentrated on what caused the loss. The sediment reached the stream due to dewatering of the work area to an 18"CMP that eventually discharged to the jurisdictional stream. As we discussed earlier, proper dewatering of the work area is a significant challenge on this project due to most of the work occurring in the median between the west and east bound lanes of 1-40/85. Evidently, water was discharged through the CMP without being properly treated. A meeting was held the following Monday (August 14, 2023) to address the issues and discuss how to prevent any future mishaps. In attendance at the meeting were the following: Chris Lamm (Virtual), Lane Construction Project Director David Chaparro, Lane Construction Project Manager Mike Roberts, Lane Construction Project Superintendent Caleb Hogsed, Lane Construction Project Engineer Lane Crocker, Lane Construction Field Engineer Denver Nixon, Nixon Contracting Owner/Manager Jerry Parker, PDEA Engineer NCDOT Della Moore, NCDOT/RK&K Josh Young (Virtual), Roadside Environmental Engineer NCDOT Patty Eason, Division Construction Engineer NCDOT Bill Snell, Division Construction Staff Engineer NCDOT Joe Lowe, Engineering Specialist II NCDOT/DRMP Jacob Crews, Senior Assistant Resident Engineer NCDOT After the collection of information and thorough discussion of the issues, it was decided that the following guidelines would be implemented: • A level II Technician would always be present when working near any permitted site. • Permitted sites would be better identified. • Any unclean water would receive treatment by ultimately going through a silt bag or skimmer basin before releasing. • Orange safety fencing would be placed around all permitted sites where feasible. • Outlet protections would be improved and better monitored. • Improved communication between equipment operators and onsite project managers • Additional training for erosion control technicians • Potential shutting down of project if future infractions occur. Please let me know if you would like to provide any additional information or if you have any questions.

As you mentioned, clean-up efforts were initiated on -site last week due to incorrect dewatering activities and a follow up meeting is scheduled for later Today. Please provide the DWR Project/Permit Number associated with this incident, photo documentation and a site map depicting the approximate location on -site. Please provide updates on the restoration efforts and estimated quantify of sediment loss as they are available.
