Cleanup Status
Note: The EPA is the lead agency for managing cleanups at this facility.
From 1852 through the 1980s, TRW disposed of waste liquids at the Danville plant in four unlined earthen disposal pits and nineteen underground storage tanks. Consequently, waste oils, solvents, and waste liquids have leaked into the soil and groundwater.
The soil was contaminated with such substance as petroleum products, volatile organic compounds, polychlorinated biphenyl (PCBs), arsenic, chromium and lead. Beginning in 1985, TRW removed all the underground storage tanks and contaminated soils.
The groundwater was contaminated with volatile organic compounds, petroleum products, and PCBs. Under the supervision of Pennsylvania Department of Environmental Protection (PADEP), TRW began operation a groundwater remediation system in April 1989 which continues to the present. The system included slurry cutoff wells, monitoring and recovery wells, a vacuum extraction system, a granulated activated carbon filter, and an air sparger. The groundwater remediation system was formalized in a February 1994 Consent Order and Agreement with PADEP (amended October, 1994). Reports required by the Order show that as of 1996, migration of the groundwater is under control.
On March 24, 1998, EPA determined that contamination in groundwater and human exposures risk from contaminants were under control. A statement of basis for corrective action with controls was posted on August 26, 2015.
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

TRW is a 250,000 square foot site located in Danville, Montour County, Pennsylvania. The major operations conducted at the plant were forging, cutting and grinding, chrome plating, and packaging of valves for various internal combustion engines. This facility is no longer operating.
Iron parts have been built on this site since 1847. TRW bought the property in 1951 and the valve division began operations in 1981. In 1983, TRW moved the part of the division that generated hazardous waste to Route 11 and Woodbine Lane in Danville (now Aldan Industries).
Contaminants at this Facility
The groundwater contains volatile organic compounds, PCBs, and petroleum products. Currently, the groundwater remediation system prevents the groundwater from migrating offsite.
Institutional and Engineering Controls at this Facility
Institutional Controls enforced through an Environmental Covenant include:
A. Land use is limited to industrial and commercial activities (excludes schools, nursing homes, day care centers, and other residential style facilitates and recreation areas), as well as limits on digging and excavation activities.
B. Groundwater use is prohibited for any purpose.
C. Routine inspections and reporting required to confirm compliance with the engineering and institutional controls.
D. Routine inspections and reporting to ensure that the physical integrity of the PSSDS vent piping, stacks, and wind turbines in the Former Steel Room is intact and the wind turbines are functional.
E. Ensure the existing asphalt/building coverage remain in place.
F. Ensure that no intrusive disturbance of the asphalt/soils overlying the slurry wall has occurred.
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.
