Site Description

This facility, located in Harriman, New York, on Route 17 at Arden House Road, manufactures organic and pharmaceutical intermediate chemicals, and has been in operation since the early 1950s. The principle products are pyridine, picolines and cyanopyridines. The production processes for these chemicals generate hazardous wastes, which are stored in tanks and containers and incinerated on-site. The on-site hazardous waste incinerator also burns fumes from process reactors, and recovers energy in the form of steam, for use in plant operations. A residential area is located across the street from this facility. Public access to the plant site is restricted by fencing and 24-hour security.

Site Responsibility and Legal Instrument

The New York State Department of Environmental Conservation (NYSDEC) Division of Environmental Remediation issued a Record of Decision (for the initiation of remedial activities) for the Nepera site in March 1997. NYSDEC is the lead agency responsible for corrective action at the site.

An Order on Consent issued by NYSDEC on March 10, 2000 requires Nepera to implement several physical modifications to its pyridine production process to reduce the likelihood of pyridine releases into the environment.

Permit Status

The storage of hazardous waste in containers at the site is regulated by a Part 373 NYSDEC permit issued on May 22, 1997. The permit was modified by NYSDEC (July 1999) to include the existing incineration operation, organic emissions from hazardous waste processes, equipment, tank and containers.

Potential Threats and Contaminants

There is ongoing in-situ on site vacuum extraction to remove benzene, toluene, xylenes and pyridine-based compounds from the groundwater. In addition, the level of mercury migrating from groundwater into the west branch of the Ramapo River is being evaluated. Groundwater, soils and possibly surface water have been impacted by past plant operations and drum disposal at the site. Groundwater is not used as a drinking water source by neighboring residents. Groundwater is contaminated with volatile organic compounds and semi-volatile organic compounds, and the plume has been contained on-site. Six monitoring wells, located along the river, are sampled quarterly, and the contaminants of concern are either at or below groundwater standards.

Cleanup Approach and Progress

The selected remedies, based on the results of a remedial investigation and feasibility study, have been implemented via a Record of Decision (ROD). The status of the selected remedies is as follows:
