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.

EPA plans to amend its 2010 Interim Record of Decision (IROD) for the Ottawa Township Flat Glass Superfund site. The amendment will affect only the portion of the remedy that specifies the preferred alternate water supply to properties with affected well water. The IROD amendment will change the preferred alternate water supply from the municipal water line extension to an individual private well into the New Richmond Sandstone aquifer for each of the affected properties.
In order to amend the IROD, EPA must provide a public notice of the proposed decision to the community and provide for a comment period and a public meeting. EPA must consider any comments received before finalizing its decision. EPA expects to offer the public comment period in the Spring of 2013.
