Background

The Ottawa Township Flat Glass site, also known as the Libby Owens Ford Plant 5 & 7 site, is located in Naplate, LaSalle County, Illinois. The 228-acre site consists of a glass manufacturing facility ("Plant #7" [currently inactive] and "Plant #5") located on the north side of the Illinois River plus former silica sand quarries, wastewater disposal areas, and a 56-acre undeveloped parcel of land. It also includes additional former silica quarries and wastewater disposal areas across from the facility on the south side of the river.

The manufacturing plant has been making flat glass products since about 1907. Arsenic trioxide was a minor ingredient in the manufacturing process from 1907 until 1970 when its use was discontinued. The final step in the manufacturing process involved grinding and polishing cast glass with fine silica sand and water. The process generated a waste slurry containing mostly sand, water, and glass particles (containing arsenic) which was discharged into the former quarries for settling of solids and discharge of overflow water into the Illinois River. The slurried waste in the settling areas contains appreciable levels of arsenic and is a source of arsenic contamination in local area groundwater as well as being a direct contact or ingestion threat to human and ecological receptors.

Pilkington North America (PNA) has owned and operated the glass manufacturing facility since 1986.

Site Updates

September 2011

On Sept. 29, 2010, EPA signed an interim Record of Decision for Operable Unit (OU) 3 of the Ottawa Township Flat Glass site. The selected remedy included the redirection of storm water flow away from the arsenic laden quarries; institutional controls to prevent future residential use and potable well installation; municipal water supply; and monitoring of ground water quality over time. Currently, EPA and PNA are negotiating an agreement for the implementation of the selected remedy.

The investigation and remedial alternative evaluation is underway for the final cleanup action for OUs 3 and 4.

EPA recently completed a community involvement plan (PDF) (55pp, 2.7MB) for this site. The plan includes the opinions and concerns of the community and discusses ways the EPA can engage the community throughout the clean-up process. In addition, a frequently asked questions has been added to this website to respond to many questions the community has about the Superfund Program in the Ottawa/Naplate area.
