Recticon/Allied Steel Corporation
Remedial Design Update - June 1996
The Recticon/Allied Steel Corporation Site is made up of two former factory facilities. Located across from each other at the inter-section of Route 724 and Wells Road in Parkersford, the two properties together cover approximately 5 acres.
The property to the west of the intersection was formerly occupied by Recticon, a subsidiary of Rockwell International and a manufacturer of silicon wafers used in computers. Recticon ceased operations at the site in 1981.
The property to the east of the intersection was occupied by a subsidiary of Allied Steel Products Corporation, Allied Steel Products Corporation of Pennsylvania (Allied PA). Allied PA custom fabricated pressurized steel vessels at this location until about 1988.
In the 1980s, both Recticon and Allied PA made efforts to address contamination found in soil and ground water. Recticon initiated a pumping and treating system to address volatile organic compounds (VOCs) in ground water and excavated and disposed contaminated soils off site. However, treatment was discontinued when the company abandoned the facility. Allied excavated soils and constructed an aeration tower to remove VOCs from ground water. The tower was never operated, and Allied PA subsequently filed a petition for bankruptcy.
A Remedial Investigation and Feasibility Study (RI/FS) was conducted by Rockwell International who signed an administrative consent order with the EPA in 1990. The RI/FS resulted in a 1993 Record of Decision (ROD).
The Cleanup Decision
On June 30, 1993, after reviewing comments received from the public, EPA signed a Record of Decision (ROD) for the Recticon/Allied Steel site. The ROD required:
- installation of a public water line to serve affected or potentially affected residents,
- excavation of contaminated soils with disposal off site,
- extraction and treatment of contaminated ground water with discharge of treated water to the Schuylkill River,
- long-term ground water monitoring,
- verification sampling for copper and zinc in the onsite drainage ditch, and
- performance of a Phase I archeological survey.
Following the ROD signing, EPA tried unsuccessfully to negotiate an agreement with potentially responsible parties (PRPs) to carry out the ROD requirements. On March 24, 1994, EPA issued a Unilateral Administrative Order (UAO) to the PRPs. The UAO requires them to implement the ROD.
Rockwell International Corporation (Rockwell) is currently implementing the selected remedies under the UAO. Between November 1994 and April 1995, Rockwell conducted field work needed to complete a remedial design investigation report. The report was approved by EPA in December 1995. The report found:
- that pumping two existing wells, one off site and one on, may intercept the plume of contaminated ground water from the site and prevent it from discharging to the Schuylkill River,
- that levels of copper and zinc which may be harmful to plants and animals have migrated off site in the drainage ditch, and
- that the cleanup actions may proceed without the need for further cultural resource investigations.
Rockwell also submitted a preliminary remedial design for the ground water extraction and treatment system to EPA on January 19, 1996. This design proposes extracting contaminated ground water at a rate of 150 to 200 gallons per minute and treating it in a refurbished portion of the existing Allied Steel building. Contaminants would be removed from the water using a low-profile air-stripping unit equipped with a vapor-phase carbon filter. Treated water would then be released into the river via underground piping.
The EPA and the Pennsylvania Department of Environmental Protection (PADEP) submitted comments on the preliminary design in mid May and approved the plan in December 1995. The draft final plan was submitted on June 14, 1996, and the final design is expected this Summer.
In addition to the above efforts, throughout 1995 and early 1996, EPA; PADEP; Rockwell; East Coventry Township officials; and the municipal water supplier, Citizens Water Company, have been working together toward an agreement on the installation of a waterline to serve residents and businesses actually, or potentially, affected by the contaminant plume from the site. Rockwell and Citizens are, reportedly, nearing agreement on the design and installation of the waterline, and EPA currently anticipates that construction will begin in late Fall 1996.
The Agency is also considering what further actions may be necessary to address the copper and zinc that has migrated into the drainage ditch at levels that could cause adverse ecological effects. When more information is available on this topic, it will be made available.
