Malvern TCE

August 1999 Fact Sheet

Design Work at the Site is now Underway

An Environmental Protection Agency remedial design Order for the Malvern TCE Site became effective on July 1, 1999, and the cleanup design process is now getting underway. Numerous companies designated by EPA as responsible parties ("RPs") for the Site have signed the Order, agreeing to conduct the needed design work. This is a significant milestone towards achievement of the remedy at the Site.

The settling PRPs are proceeding with the work required to begin design activities for construction of the waterline which is part of the overall agreement. The PRPs have hired de maximus, inc. to act as their project coordinator and have entered into discussions with the Philadelphia Suburban Water Company (PSWC), the water provider in the area. EPA expects the PRPs to accelerate construction of a waterline to affected residential areas in order to provide a permanent source of safe drinking water. This portion of the remedy can be constructed as a separate phase due to the existence of nearby waterline connections and standard engineering procedures for waterline installation.

The remedy for the Site was selected in November 1997 and this agreement will commence the design of the following major components:

Water Supply
Installation of a waterline to prevent contact with groundwater contamination at residences affected or potentially affected by the Site.
Main Plant Area Soils
Installation of a cap to prevent direct contact with contaminated soils at the Main Plant and to reduce the potential migration of these contaminants to the groundwater.
Main Plant Area Groundwater Plume
Extraction and treatment of groundwater via air stripping followed by carbon adsorption or ultraviolet oxidation; subsequent injection of treated water to the aquifer to restore the Site groundwater to beneficial use by reducing contaminant concentrations to protective levels.
Former Disposal Area/Mounded Area Soils
Excavation, off-site treatment and disposal of contaminated soils to reduce the potential for migration of contaminants in these soils to groundwater.
Former Disposal Area/Mounded Area Groundwater Plume
Implementation of a natural attenuation program to monitor reduction of contaminant concentrations in groundwater to protective levels.

The owners of the Site are not parties to the design order and the RPs who have signed the order must acquire access to a portion of the Site owned by the Chemclene Corporation before the design of the work on the Chemclene property can begin.

De minimis parties

EPA signed a de minimis settlement on May 21, 1999. In December 1998, EPA offered approximately 300 companies the opportunity to participate in a de minimis settlement to resolve their liability as generators, brokers or transporters of waste to the site. This settlement provides that in return for a specified cost payment to EPA by a de minimis party, EPA will agree not to sue or take any other civil or administrative action against the settling party. EPA anticipates collecting approximately $3.8 million to be used for cleanup at the Site and to reimburse EPA's past costs in investigating the Site. The de minimis settlement was subject to a one month comment period which ended on August 7, 1999.

Current Site Status

The health and safety of the community surrounding the Site is EPA's primary concern. To help insure that the water they receive is safe, EPA will be conducting the routine sampling and analysis of all home wells during September 1999. Homeowners will be contacted by EPA's contractor, the Roy F. Weston Company, for appointments. Additionally, homes with carbon filters will have their units serviced during November 1999.

The homes that are affected or potentially affected by the Site are sampled at least once a year to assess whether chemicals are present at an unacceptable level. Addi-tionally, EPA maintains carbon filter treatment systems at 18 residences which have been affected by contami-nation, and provides sampling results to each resident.

EPA also issued an Administrative Order (Order) to the owner/operator of the Site in June 1998, requiring them to conduct a portion of the cleanup activities required at the Main Plant Area (MPA) of the Chemclene property. The plan detailing how this work is to be implemented has been approved and the work is expected to begin by the Fall of 1999.

The owner/operator is required to:

Information Meeting

EPA will available to discuss any issues relating to the cleanup of the Site on Wednesday, September 22, 1999 at the Great Valley High School. The information session will be held at 7:30 p.m. Details will be sent to area residents in a mailing.

A legal document signed by EPA directing an individual, business or other entity to take corrective action or refrain from an activity. It describes the violations and actions to be taken, and can be enforced in court.
De Minimis Parties
Companies or individuals who contributed a relatively small amount of waste to the site. For the Malvern Site, parties that contributed 0.75% or less of the total waste sent to the site for processing are considered de minimis parties.
Non-De Minimis Parties
Companies or individuals who contributed in excess of 0.75% of the total waste sent to the site for processing.
Record of Decision (ROD
A document that announces and explains EPA's selected cleanup method(s). The ROD is based on information gathered during the remedial investigation and feasibility study and on comments received during the public comment period.
Responsible Parties
Present or former owners or operators of the site; companies/persons who arranged for treatment and/or disposal of hazardous substances at the site; or companies/persons who accepted hazardous substances for transport to the site for treatment or disposal. Whenever possible, through administrative and legal actions, EPA requires the responsible parties to clean up hazardous waste sites they have contaminated.

The Chemclene Fire: An Update

Under Control

The United States EPA is currently stabilizing any hazardous substances at the Malvern TCE Superfund Site that may pose a potential threat to human health and/or the environment as a result of the fire on August 12, 1999 that destroyed the main building at the Site. The former building housed much of Chemclene Corporation's present operation which involves the sale of hydraulic oil, cleaning solvents, and hydrogen peroxide. Chemeclene's current operation is regulated by the East Whiteland Township Fire Marshal's office which is investigating the cause of the fire. As a result of the fire, EPA has issued an order to Chemclene Corporation and its owner Lloyd Balderston, to immediately begin securing hazardous substances stored at the Site and to clean up any environmental contamination that may have occurred from the fire. Should Chemclene and its owner fail to comply with the terms of the order, EPA will perform these necessary cleanup activities.

Effects on Cleanup

In addition to conducting cleanup activities required as a result of the fire, EPA will evaluate the potential impacts of the fire on the comprehensive cleanup planned for the Site. The cleanup remedy for the Site was selected by EPA in 1997 to address contamination at the property resulting from the former Chemclene solvents recycling operation. From 1952 until 1992, Chemclene Corporation sold and reclaimed industrial cleaning solvents. The former processing, chemical storage, and waste management practices at Chemclene have lead to volatile organic contamination in the soil and ground water. Although Chemclene no longer reclaims waste solvents the company continues to operate a hauling operation and sells hydraulic fluid and hydrogen peroxide from the Site.

In addition to the work being conducted by the settling PRPs, Chemclene Corporation and its owner Lloyd Balderston are required to conduct a portion of the Main Plant Area cleanup activities under an Order issued by EPA. EPA will evaluate the work to be conducted by the owner in light of the fire. EPA has directed the owner/operator not to commence any activities on-site until directed by EPA or the local Fire Marshall.

Waterline Installation

The cleanup remedy for the Site, selected in 1997, will be performed by the potentially responsible parties for the Site. A settlement agreement for the implementation of the remedial design and remedial action of the remedy was recently signed by EPA and the settling defendants. The Responsible Parties are proceeding with the design of the remedy, including the design of a waterline to residents affected or potentially affected by groundwater contamination from the Site. The schedule for design and construction of the waterline should not be affected by the recent fire at the Site.
