Malvern TCE

July 1998 Fact Sheet

EPA Offers Settlement to Responsible Parties

Responsible parties are present or former owners and/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.

The U.S. Environmental Protection Agency (EPA) recently mailed letters to all identified parties responsible for the contamination at the Malvern TCE Superfund Site. These letters notified the responsible parties that they must pay for the cost of the site cleanup, including reimbursing EPA for all previous costs associated with the cleanup.

On April 30, 1998, EPA mailed letters to approximately 250 de minimis parties offering them the opportunity to participate in a de minimis settlement and to settle their liability as generators, brokers or transporters of waste to the site. The settlement allows these parties the opportunity to contribute to the cleanup costs in return for a guarantee from EPA that they will not be sued in the future for site-related cleanup activities.

On May 4, 1998, EPA mailed special notice letters to approximately 50 non-de minimis responsible parties. Responsible parties who received special notice letters are required to reimburse EPA's past costs as well as estimated future costs, and to implement and fund the remedy for the site. These letters give the parties an opportunity to negotiate a consent decree to perform the work required by the Record of Decision (ROD), a document that announces and explains EPA's selected cleanup method.

Responsible parties receiving special notice letters included Lloyd Balderston, Ruth Balderston and Chemclene Corp. Chemclene is the current owner of the site, Ruth Balderston is the former site owner, and Lloyd Balderston was the operator of the site during the time that contamination occurred. In addition to the owner/operator parties, companies who generated or transported waste to the site also received special notice letters.

EPA also issued an Order to Chemclene, Lloyd Balderston and Ruth Balderston to conduct certain cleanup plan activities outlined in the November 1997 ROD. Each activity that the owner/operators must conduct is part of the plan to clean up the Main Plant Area (MPA). The Order requires the owner/operators to:

De Minimis Parties are those companies or individuals who contributed a relatively small amount of waste to the site. EPA established a cut-off for de minimis eligibility using a percentage of the total waste sent to the site by all the responsible parties. For the Malvern Site, a responsible party is eligible to participate in the de minimis settlement if its contribution of hazardous substances to the site is at or less than 0.75% of the total waste sent to the site for processing.


The de minimis parties had until May 31, 1998, to review the terms of the settlement and respond to EPA with any comments. EPA will finalize the settlement and notify the parties that they have 30 days to sign the settlement and return it to EPA.

Upon receipt of the letters, the non-de minimis parties have 60 days to respond to EPA with a Good Faith Offer. A Good Faith Offer is a response from the parties to EPA stating that they are willing to participate in negotiations and implement the design and construction of the remedy. If EPA receives a Good Faith Offer, an additional 60 days is set aside to negotiate a Consent Decree between the parties and EPA.

Once EPA completes negotiations, the remedial design phase of the cleanup can begin. This is the phase in which the cleanup plan is designed. Upon completion of the remedial design phase, the remedial action (the actual construction of the cleanup) will begin. EPA anticipates that construction will begin in the spring of 2000.
