Cleanup Status
In August 2003, EPA, PADEP, and EPA’s contractor conducted a site visit to assess the current condition at the facility. The purpose of the visit is to determine if the facility meets the Environmental Indicators (EIs) for Human Exposures and Migration of Contaminated Groundwater.
In April 2004, Neville Chemical signed a new Consent Order and Agreement (Order) with the Pennsylvania Department of Environmental Protection Agency (PADEP) to improve the groundwater remediation system to stabilize the groundwater contamination beneath the Facility. Neville Chemical installed additional recovery wells along the Ohio River and increased the hydraulic capture of the existing groundwater remediation system to control the migration of the groundwater plume. The upgrade and expansion of the groundwater remediation consisted of the installation of submersible pumps in all the recovery wells, the installation of additional Light Non-Aqueous Phase Liquid (LNAPL) interceptor wells, the expansion of the air stripper capacity with vapor phase carbon to treat the additional flow rate and the installment of the eight piezometers along the Main Channel Property along the Ohio River to monitor the capture zone of the remediation system to assess the system’s effectiveness in eliminating the potential for offsite migration of LNAPL. The piezometers are screened across the water table to allow for an accurate in-well measurement of LNAPL.
The Allegheny County Health Department (ACHD) is addressing the Volatile Organic Compound (VOC) air emissions onsite, specifically the resin rework area and the wastewater treatment tanks. Neville Chemical will install temperature control lockout and additional operating procedures for maintaining effective compliance at the resin rework area and will install covers over the wastewater treatment tanks. In addition to the work at the Neville Chemical facility, the ACHD will conduct a 2-year air quality study in and around Neville Island to evaluate the air quality in the region.
The EPA determined the Environmental Indicator for Current Human Exposures Under Control was completed on June 29, 2005. The Environmental Indicator for Current Migration of Groundwater Under Control was completed on August 19,2021.
Site Description
Interactive map of Neville Chemical Company, Pittsburgh, PA
. View larger mapNeville Chemical Company is a manufacturer of synthetic hydrocarbon resins and coumarone-indene resins. Established in 1925, Neville Chemical Company is privately owned with the Corporate Headquarters and main manufacturing facility located on Neville Island. The Island is located in the Ohio River, six miles west of Pittsburgh, Pennsylvania. The Facility occupies approximately 68 acres.
Synthetic resins are produced from two primary raw materials. The first is a crude heavy solvent naphtha obtained during the production of coke from coal. This is used to manufacture Neville's coumarone-indene resins. The second is petroleum streams obtained during the cracking or chemical treatment of petroleum. These are used to manufacture Neville's petroleum hydrocarbon resins.
Contaminants at this Facility
A Light Non-Aqueous Phase Liquid (LNAPL) was identified in six of the twenty-two monitoring wells as well as six recovery wells. A central Benzene, Toluene, Ethylbenzene, and Xylene (BTEX)-plume and a chlorinated plume exist near the northwest corner of the property. The plume migrates northward and discharges to the Ohio River from a number of historic release areas.
