(#99107) NEW YORK, N.Y. -- Alcoa began work this week to clean up soils and sediments contaminated with polychlorinated biphenyls and lead at the York Oil federal Superfund site in Moira, New York, the U.S. Environmental Protection Agency announced today. The site, a former waste oil recycling and storage facility, accepted waste oil from a number of companies, including Alcoa. The facility was improperly managed and operated and, as a result, soils on the York Oil property and nearby wetlands sediments and groundwater were contaminated.

EPA issued a Superfund Unilateral Order on December 31, 1998 requiring Alcoa to excavate, treat and dispose of the contaminated wetlands sediments. Alcoa agreed to start this cleanup to coincide with the company's existing plans, under the terms of a previous agreement with EPA, to excavate and treat the contaminated soils and treat the groundwater at the facility. The company recognized it could save about $1 million in costs by jump-starting the cleanup of the wetlands sediments when cleanup of the contaminated soils was set to begin. The contaminated soils and groundwater at the facility are the source of the contamination of the nearby wetlands, sediments and area groundwater.

"We are very pleased about the work starting on this phase of the cleanup and the dual track approach the company is taking to correct the problems caused by the contamination," EPA Regional Administrator Jeanne M. Fox said. "We issued the Order so that the hazards posed by the site can be addressed as soon as possible."

Numerous other parties have reimbursed Alcoa for part of the cost of cleaning up contaminated soils and groundwater at the site and to reimburse EPA for costs incurred through the date of that settlement. In early June, EPA began negotiations with numerous parties that contributed waste oil and other contaminants to the site. The Agency expects these parties to reimburse Alcoa for their share of the cleanup costs for the contaminated sediments in the surrounding wetlands, and to repay EPA for the costs it has incurred since the previous settlement.

The Agency expects that, when combined with the removal of the sources of contamination, within a reasonable time frame, the gradual breakdown of the contaminants in the area groundwater will return the quality of the groundwater in the wetlands south of the facility to a level that meets federal and state standards. This breakdown process is called "natural attenuation." Under the Order, Alcoa also will perform long-term monitoring of the groundwater to measure the effectiveness of the natural attenuation process in reducing the contamination level. To further protect public health, EPA's plan also calls for a prohibition on the installation of drinking water wells in the area where the groundwater is contaminated.

These cleanup plans are based on the findings of an investigation into the extent of contamination in sediments and groundwater at the site. The investigation and studies were conducted under EPA supervision by some of the parties deemed responsible for causing the problem.
