Off-Site Contamination — From 1971 until shortly before the mill closed in 2002, Georgia Pacific operated a "co-generation" electrical generation plant burning mill waste and allegedly other materials. Fly ash from the co-generation plant, containing toxins including dioxins and furans was stored on site, and trucked off-site to be used as soil amendments on fields, lawns and gardens.
