NYSDEC Superfund Sites

Honeywell has completed the initial site investigation. Completion of a supplemental investigation is anticipated to be completed in March 2023 at Site 108, which is adjacent to the Niagara River. The company worked proactively with EPA since late 2018 to address priority environmental issues associated with Site 108.

Sites 109 and 110 were previously investigated and a remedial decision was issued under the state Superfund Program. However, these two sites are being further investigated, and a Focused Feasibility Study will be prepared to determine if the change in site use warrants additional remedial action.

Site 109 and Site 110

Site 109 is located just east of River Road on the western side of the main parcel. In 1977, an unknown quantity of brick, rubble, and related demolition waste was disposed in this area. Site 110 is in the northeast corner of the property east of River Road at the rear of the former plant. Materials such as coal tar sludge, fly ash and cinders were reportedly disposed of in this area. The disposal activities occurred prior to 1978.
