Notice of Listing on the Pennsylvania Priority List of Hazardous Sites for Remedial Response; Hazardous Sites Cleanup Act
[40 Pa.B. 5250]
[Saturday, September 11, 2010]
Bishop Tube Site, East Whiteland Township,
Chester County1. Background
The Hazardous Sites Cleanup Act (HSCA) (35 P. S. §§ 6020.101—6020.1305) was enacted in 1988 to provide for the cleanup of sites in the Commonwealth that are releasing or threatening the release of hazardous substances. Section 502(a) of HSCA (35 P. S. § 6020.502) requires that the Department of Environmental Protection (Department) publish in the Pennsylvania Bulletin a priority list of sites with releases or threatened releases for the purpose of taking remedial response. This list is called the Pennsylvania Priority List of Hazardous Sites for Remedial Response (PAPL). The Department places sites on the PAPL when the Department has determined through investigation that there are releases or threatened releases of hazardous substances, or releases or substantial threatened releases of contaminants, which present a substantial threat to the public health, safety and environment. In accordance with the requirements of section 502(a) of HSCA, the Hazard Ranking System (HRS); (40 CFR Part 300, Appendix A) established under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980 (42 U.S.C.A. §§ 9601—9675), is utilized to rank the sites for placement on the PAPL. The HRS uses mathematical formulas that reflect the relative importance and interrelationships of the various human health and environmental factors to arrive at a final score on a scale of 0 to 100. The values are assigned using information obtained from site investigations. Section 502(a) of HSCA also directs the Department to consider its administrative, enforcement and financial capabilities when placing sites on the PAPL. HRS scores are finalized by the Department using the HRS in effect at the time the score is prepared and the proposed listing notice is issued under the statute.
The HRS was developed by the United States Environmental Protection Agency (EPA) as the method used to evaluate the relative potential of hazardous substance releases to cause health or safety problems, or ecological or environmental damage. It is the principal mechanism for placing a site on the National Priorities List, the list of priority releases for long-term remedial evaluation and response under CERCLA. The HRS is calculated by utilizing known information to establish the level of threat presented in four potential pathways of human or environmental exposure: groundwater, surface water, air and soil exposure. Within each pathway of exposure, the HRS considers three categories of factors:
(1) Factors that indicate the presence or likelihood of a release to the environment.
(2) Factors that indicate the nature and quantity of the substances presenting the potential threat.
(3) Factors that indicate the human or environmental targets potentially at risk from the site.
The resultant HRS score represents an estimate of the relative probability and magnitude of harm to human populations or sensitive environments from potential exposure to hazardous substances by the groundwater, surface water, soil exposure or air pathways.
2. Summary and Purpose
Placement of a site on the PAPL is used to identify sites that need further study and/or remedial response decisions to address threats to the public health, safety or the environment. The Department will decide on a case-by-case basis whether to take enforcement or other actions under HSCA or other authorities, and/or to proceed directly with HSCA-funded remedial response actions and seek cost recovery after the cleanup.
Remedial response actions will not necessarily be taken in the same order as a site's ranking on the PAPL. The investigation conducted to place a site on the PAPL may not be sufficient to determine either the extent of contamination or the appropriate response actions for a site. The Department may undertake further site investigation and/or an analysis of remedial alternatives to determine appropriate response actions. The length of time needed to complete these studies will vary due to the complexity of a site. Response action decisions and implementation will proceed on individual sites regardless of the progress at other sites. Given the limited resources available in the Hazardous Sites Cleanup Fund, the Department must carefully balance the relative needs for response at the sites it has studied. The Department may decide not to immediately proceed with a HSCA remedial action or that no remedial action is necessary.
3. Technical Evaluation Grants under Act 108
Under section 510 of HSCA (35 P. S. § 6020.510), the Department may make available a reasonable sum as a grant to the governing body of the host municipality of a site where the Department is considering a remedial response. The host municipality shall use this sum solely to conduct an independent technical evaluation of the proposed remedial response. The grant shall not exceed $50,000. Information and a technical evaluation grant package may be obtained from the Department's regional office in which the site is located. Refer to the Additional Information section of this notice.
A municipality will be sent grant information by the Department after a listing announcement has been published in the Pennsylvania Bulletin. The grant will be signed; however, the grant will not be effective until the proposed remedial response is available for public review. At that time, the municipality may proceed with the review of the Department's proposed remedial response.

F. Site Listing Summaries
Bishop Tube Site
The Site is a former steel tube manufacturing facility located in East Whiteland Township, Chester County. Land uses at the Site include industrial, commercial and residential. Groundwater, soil and surface water at the Site are contaminated with trichloroethylene (TCE), which is classified as a probable human carcinogen by the EPA. TCE has been detected in onsite groundwater at concentrations exceeding 100,000 parts per billion (ppb). A residential well located approximately 1/3 mile from the Site contains TCE in excess of 5 ppb, the Maximum Contaminant Level for public water supplies and the Statewide Health Standard for groundwater cleanup. TCE contaminated soils on the 13.7-acre former Bishop Tube Company property are the source of the TCE contamination in the groundwater. TCE has also been detected in indoor air in four of five homes selected for indoor air sampling. Volatilization of TCE from groundwater is most likely responsible for these detections. At one home, the concentration of TCE exceeded the Indoor Air Criterion under the Statewide Health Standard of 12 micrograms per cubic meter. TCE attributed to the Site has also been detected in Little Valley Creek, which has been designated as an Exceptional Value stream by the Department.
From 2000-2008, the Department performed surface water, groundwater and soil investigations at the Site. Under the terms of a Consent Order and Agreement with the current Site owner, the Department completed a Prompt Interim Response, installing an air sparging/soil vapor extraction system to address TCE contaminated soil in three source areas at the Site. A former Site owner/operator installed a point of entry treatment system on the residential well that exceeded the MCL for TCE. A group of former Site owners/operators is currently performing a Remedial Investigation to further characterize deep groundwater and offsite contamination, including an assessment of the vapor intrusion pathway. None of the potentially responsible parties have indicated that they are willing to conduct the additional remedial action required at the Site.
