NCO085511 I11 12I 20/09/21 117 18 i c i Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) Linda Wiggs (DWR) met onsite with Brendan Kelley (WTP Supervisor). Discussions focused much on solids management, cost and plant shut down. Both lagoons level of solids was high (-1-2' from surface). Brendan stated from one lagoon that sludge was removed with a rented dredge and belt press system from Bionomic Services beginning on December 3rd, 2019 and ending on January 21st, 2020. They were able to press and remove 100 dry tons of alum sludge and transport to Republic Waste Services in Lenoir, NC. Since the City is no longer allowed to bring their Alum Sludge to MSD, this removal had an increase cost of --$100k. Brendan stated that this facility produces the most sludge of all of the City of Asheville WTPs. The above noted removal was from one lagoon. The other lagoon is in need of removal as well and the lagoon that had the sludge removed appears to already need it again. The City is considering several options for future solids management. This WTP stopped production last week and will likely remain shut down for —6-8 months.
