A Risk Assessment was submitted in June 2013 but was deemed technically deficient by PADEP in September. A revision addressing the deficiencies is expected to be submitted in the near future.
The Remedial Investigation addressing chlorinated solvent contamination at the facility was submitted in October 2011 and approved in December 2011. Soil contamination is generally limited to source areas, the majority of which have been removed. The soil vapor extraction system continues to extract volatile contaminants from the primary source area. Groundwater contamination is more widespread and several options for cleanup are being assessed. A 56-tree phytoremediation plot was planted between the main source area and the eastern property boundary in 2012 to help contain and treat contaminated groundwater. A bioremediation pilot test is also planned for the near future near the downgradient property boundary.
The former Robertshaw facility was constructed between 1959 and 1960 on a 193-acre plot of land in New Stanton, Pennsylvania. The facility manufactured various controls for residential and commercial appliances including electric and gas thermostats for ranges and water heaters, pressure switches and regulators, valves, timers, sensors, and other miscellaneous components. The facility has been operated by Siebe Appliance Controls and is currently owned by Invensys Appliance Controls, who purchased the facility from Robertshaw in 2000. Appliance control manufacturing operations have been inactive since January 2000. Westinghouse currently leases a majority of the facility and has occupied a portion of it since 2000.
Remedial investigations and cleanup of the facility began soon after plant closure in 2000, and the facility entered the Act 2 Program in February 2001. The Final Report addressing the impacts from mercury contamination to the facility was approved in April 2011. The Final Report included an environmental covenant that codified restrictions on groundwater and land use at the facility, in addition to containing a Soil Management Plan for any necessary future land disturbances. Remedial measures addressing volatile contaminants are ongoing.
Primary contaminants at the facility include chlorinated volatile organic compounds including trichloroethene and trichloroethane and their degradation products, in addition to tetrachloroethene and mercury. Groundwater, soil, and sediment at the facility are known to be contaminated; however, exposures to these media are limited to intrusive activities typically conducted by personnel using appropriate protective measures. Groundwater is not used as a drinking water source in the vicinity of the facility. The potential for vapor intrusion into facility buildings is currently mitigated through the use of the soil vapor extraction system.

The facility has been reused primarily as warehousing space; Westinghouse presently leases a majority of the facility.
