Cleanup Status
Note: The EPA is the lead agency for managing cleanups at this facility.
The Corrective Action Final Decision of Complete without Controls became effective October 2, 2012, after a 30-day public comment period. No further action is required to make the Knoll property suitable for any type of land use.
An Environmental Inspection (EI) was performed at the Knoll facility in September 2007. This inspection summarized several prior investigations including the preliminary assessment of 1989, several underground storage tank (UST) investigations and closures in the 1990s, and an incinerator dismantling/removal in 2002. The EI inspection identified several potential areas of concern, mostly associated with past UST closures and their impact to soil and groundwater in the area. Upon further investigation that included a site visit in June 2012, adequate remediation appears to have been performed. The monitoring well network adequately covered the UST areas and revealed little to no impact from previous UST activities. On July 2012, EPA determined that contamination in groundwater and human exposures risk from contaminants were under control.
Cleanup Actions or environmental indicators characterizing the entire facility are shown below. It is not intended as an extensive list of milestones/activities. This listing, and all the data on this page, come from EPA’s RCRAInfo and are refreshed nightly to this page. For this table and the Cleanup Activities Pertaining to a Portion of the Facility table that follows, a blank in the Status column could mean the action either has not occurred or has not been reported in RCRAInfo.

Facility Description
Link to a larger, interactive view of the map.
The Knoll facility is situated on 99 acres of land located in Upper Hanover Township, Montgomery County, Pennsylvania. The facility was built in 1964 and has produced office furniture, partitions, fixtures, and office systems throughout its history to the present. The facility comprises three separate buildings: the Fabrication building (original main facility), the Schlosser Warehouse building (completed in 1985), and the Lubin Assembly building (completed in 1986). The Fabrication building, as the main facility building and the location of any hazardous waste generation or handling, is the primary focus for Resource Conservation and Recovery Act (RCRA) Corrective Action purposes.
Contaminants at this Facility
Primary contaminants at the facility include volatile organic chemicals associated with petroleum hydrocarbons from previous UST use, and solvents and metals associated with painting operations; however, after the remediation of the USTs, little evidence of any contamination remains at the facility.
Institutional and Engineering Controls at this Facility
Institutional controls were not required at the site.
Institutional and Engineering Controls help ensure human exposure and groundwater migration are under control at a cleanup facility. Where control types have been reported by states and EPA in EPA’s RCRAInfo, they are shown below. Not all control types are needed at all facilities, and some facilities do not require any controls. Where there are blanks, the control types may not be needed, may not be in place, or may not be reported in RCRAInfo.
