KINGSPORT, Tennessee — Vera Gilmer, a 30-year Kingsport resident, arrived at the Kingsport Economic Development Board meeting for the update on Domtar’s packaging mill. She shared her frustration with the board about the mill’s odor over the last month. …Gilmer stressed that the smell has worsened recently. …Domtar mill manager Troy Wilson gave an update on the digester’s construction and addressed what could possibly worsen Domtar’s odor in the meantime. …Wilson said worsening odor is likely attributable to Domtar’s current wastewater treatment system, a lagoon system which he described as “antiquated” and sensitive to the weather. He also shared that the rainstorm that passed over Kingsport Wednesday last week put a strain on the wastewater system. …Domtar has spent $20 million on the digester so far. At its peak, the digester project will employ 140 people, according to Wilson.
