Armstrong World Industries - St. Helens

Summary Information
(last updated on: 12/16/2020 9:47:40 AM)
(December 2020) The Armstrong World Industries project is located in St. Helens, Oregon. The property is 175 acres and was used for ceiling tile manufacturing from 1929 until the plant closed on May 10, 2018. The property has been divided into the upland area (36 acres) and the lowland/in-water area for purposes of reporting. Wastewater from the upland facility historically discharged to the lowland area until the 1960s when a treatment plant was constructed. Effluent from the plant was discharged to the lowland area until 1989 when Armstrong World Industries purchased the property. Armstrong World Industries, Kaiser Gypsum, and Owens Corning are all party to a remedial investigation/feasibility study Consent Order. The draft remedial investigation reports and human health risk assessment reports (upland and lowland/in-water) and the ecological risk assessment report (lowland/in-water) were submitted in August 2013, November 2013 and February 2014. DEQ issued comments on five documents in March 2015. The primary contaminants being addressed at the property include dioxins, furans, arsenic, and mercury. Data are available for soil, groundwater, surface water, catch basin solids, sediment and tissue. In October 2016 Kaiser Gypsum filed for bankruptcy delaying work in the lowland/in-water area. As part of the bankruptcy, DEQ reached settlements with Armstrong and Owens Corning. DEQ has also reached a settlement with Kaiser which is contingent on the bankruptcy being resolved. The combined settlements will be used to fund cleanup as well as habitat restoration and mitigation projects in the Scappoose Bay watershed. In October 2020, DEQ began a data gaps investigation needed to support the lowland feasibility study. DEQ issued its final cleanup plan - or Record of Decision - for the upland area in June 2018. The upland cleanup was completed in Summer 2019 and includes excavation of surface soil hot spots, offsite disposal, and installation of gravel and asphalt cap. DEQ began a data gaps investigation in October 2020 to gather information needed to support the lowland feasibility study.
