- FAIRMONT COKE WORKS SUPERFUND SITE

FAIRMONT, WV

I. Introduction

Exxon Corporation is one of the worlds' largest energy and petrochemical companies. The company engages in all aspects of the oil and gas business, from exploration and production to refining and marketing. Exxon is also a leading worldwide producer of petrochemicals and has interests in coal and minerals mining operations and electric power generation. The company employs some 82,000 people in more than 100 countries on six continents.

It is Exxon's policy to conduct its business in a manner that is compatible with the balanced environmental and economic needs of the communities in which it operates. Exxon is committed to continuous efforts to improve environmental performance throughout its activities. During the 1990's, we have dedicated considerable efforts and resources to the worldwide implementation of our Operations Integrity Management System (OIMS) and other programs focused on improving our environmental, health and safety performance. The results show that we're meeting that objective:

Exxon has a long history in the type of stakeholder processes and superior environmental performance programs that underlie the XL concept. In addition to participating in various governmental advisory groups around the world, we work hard to establish cooperative relationships with the many communities in which we operate and with environmental organizations. Exxon encourages its employees to become active in community programs, often supporting their efforts with financial grants. Recycling programs, involvement in local emergency response teams, health care clinics, and home safety training are just a few of the many activities Exxon volunteers pursue. Exxon sends employee teams to visit primary and secondary schools to interest students and support teachers in science education, and have given summer jobs to promising students. In the U.S., teams of Exxon employees provide local science teachers with information and materials to help stimulate student interest in science. Many Exxon sites annually hold an open house for the public. Neighbors can visit the workplace and talk with our employees.

As citizen awareness continues to rise, community interests have become increasingly important to Exxon. From the onset of a project, we involve local residents and community leaders. For example, at our multi-billion dollar La Barge Gas Processing Facility in southwestern Wyoming, Exxon utilized a stakeholder process, unprecedented at the time, that involved not just local, State and Federal government, and statewide and national environmental organizations, but nearly the entire population of the host community. The holistic nature of the environmental planning for this project, which considered both a full range of regulated and non-regulated environmental issues as well as the socioeconomic effects of the project, provides part of the extensive experience that Exxon has brought to bear on the proposed Sharon Steel Corporation - Fairmont Coke Works Superfund Site XL Project.

This Project will be managed by the Exxon Company, U.S.A. Site Remediation organization. Headquartered in New Jersey, this organization manages 14 site remediation projects in the U.S. Together, they bring a wealth of experience to the Fairmont XL Project. Additionally, Exxon utilizes several research and technology organizations that provide state-of-the-art support to Exxon affiliates world-wide. Exxon Research and Engineering Co. and Exxon Biomedical Sciences, Inc. staff are actively advancing site remediation technologies in the areas of characterization, risk assessment, analytical chemistry and quality assurance methods, and remedial options. These resources are available to support the Fairmont XL Project.

Exxon has significant experience in the communications associated with environmental matters and stakeholder processes, will conduct a highly effective communications program throughout this project, and will share its experience with others to facilitate improvements in industry performance. Exxon is a proponent of programs in regulatory flexibility which could lead to more cost-effective selection of risk management options with environmental benefits for the community.

II. Fairmont Coke Works Superfund Site

The Sharon Steel Corporation - Fairmont Coke Works Superfund Site (Site) is located in Fairmont, Marion County, West Virginia. As illustrated in Figure 1, Fairmont, WV sits along the I-79 industrial corridor, approximately 20 miles south of Morgantown, WV and 20 miles north of Clarksburg, WV.

The original 44.6 acres of the current Site was purchased by Domestic Coke Corporation (Domestic Coke) in 1918. Domestic Coke was a wholly-owned subsidiary of Standard Oil of New Jersey, the corporate predecessor to Exxon Corporation. The land was conveyed by Domestic Coke the day after purchase to the U.S. Ordnance Department " . . . for the construction and/or operation of a sixty oven by-product coke plant for the making of toluol and other products." The Fairmont Coke Works (Coke Plant) was built by the U.S. Department of War during 1918-1920. The land with improvements was then reconveyed to Domestic Coke in 1920. As illustrated in Figure 2, Domestic Coke made other miscellaneous land purchases from 1919-1929 to bring the total acreage of the Coke Plant to approximately 103 acres; all process units are located within an approximately 50 acre parcel within the center of the site. Domestic Coke operated the Coke Plant from 1920 to 1948.

Sharon Steel Corporation (Sharon Steel) purchased the property, Coke Plant and business from Domestic Coke in 1948. Sharon Steel operated the Coke Plant from 1948 to 1979. The Coke Plant was closed in 1979 following Sharon Steel's reported failure to comply with Clear Air Act / Clean Water Act regulations. Sharon Steel was liquidated under jurisdiction of bankruptcy court in 1991. As part of the liquidation, FAC, Inc., a subsidiary of Sharon Specialty Steel Corporation, became and remains the owner of record. Exxon has executed a Sales Agreement with FAC, Inc. to purchase the site; the transition will be completed in June 1998.

The U.S. Environmental Protection Agency (EPA) began evaluating the Site for inclusion on the National Priority List (NPL) in 1987. The Site was listed on the NPL on December 23, 1996. EPA then began the process of looking for potentially responsible parties (PRPs) to perform various investigation and remediation tasks at this Site. Because of Sharon Steel's bankruptcy and Exxon's prior ownership, Exxon signed a Comprehen Administrative Order on Consent (AOC) with EPA to conduct a Remedial Investigation / Feasibility Study (RI/FS), and Risk Assessment for the Site in September, 1997. Currently, Exxon is the only PRP with an AOC for this Site.

The Fairmont Coke Works is currently inactive; the Site was abandoned by Sharon Steel in 1979. Approximately 50 acres of the Site were used for coke plant operations. The rest of the Site consists of a wooded hillside which descends to the Monongahela River. The Site is one of the few large areas of flat, developable industrial land along I-79 in West Virginia.

III. Project Description

Exxon proposes an alternative, streamlined, cost-effective strategy for the investigation, risk assessment, remedy selection and remediation of the Sharon Steel Corporation - Fairmont Coke Works Superfund Site in Fairmont, WV. Implemented through Project XL, this strategy will result in a faster cleanup at this Site, and will more quickly return a large, flat, developable site to productive use, and provide economic growth to the Fairmont area. This Project will also achieve regulatory objectives using sound science and risk-based management, employing alternative approaches to Superfund that will ultimately meet the intent of the National Contingency Plan (NCP) and CERCLA. Key elements within this Project XL proposal are the introduction of more cost-effective flexibility to the Superfund administrative process while achieving superior environmental performance through stakeholder involvement. The Fairmont XL Project would be a pilot program for Exxon, the EPA and West Virginia Division of Environmental Protection (WVDEP) to demonstrate concepts in the Superfund program that are currently being considered, developed, and/or implemented in other regulatory programs and jurisdictions. Once established, these demonstrated alternatives can be transferable, under certain circumstances, to other Superfund sites.

Stakeholder involvement is essential to the implementation of this innovative regulatory program. Therefore, Exxon has engaged and will continue to involve a wide range of stakeholders. Potential direct participant stakeholders include: local environmental activists; educators; health care providers; emergency responders; local college students; homemakers and community volunteers; an agriculture representative; a small business owner; a senior citizen; a member of the clergy; a non-professional/hourly worker; a local elected official; a city representative; and the EPA and WVDEP regulatory agencies.

While retaining the time tables and schedules in the existing AOC between Exxon and the EPA as an enforceable commitment, the AOC would be revised to replace the more burdensome administrative requirements and guidelines with a streamlined approach. This approach will achieve superior environmental results, greater economic opportunity, and community benefit through a faster and better cleanup process. Avoiding the usual legal and administrative delays associated with Superfund will allow Exxon, the EPA and WVDEP to conduct a cleanup program that meets the intent of the NCP and CERCLA while generating superior environmental performance through a program developed by stakeholders. As part of the proposed comprehensive approach to manage potential site risks, other programs which may be applicable at Superfund sites (e.g., Natural Resources Management, Endangered Species Act, Clean Water Act, WV Groundwater Protection Act and associated regulations, and City of Fairmont Waste Management ordinances) will be integrated into the Fairmont XL Project.

IV. Project Selection Criteria

The Fairmont XL Project meets the eight XL criteria for project selection. The relationship of the Project to each of the XL criteria is discussed in detail in the following sections:
ELEMENT
SUPERFUND APPROACH
XL PROPOSAL
BENEFITS
Data Collection / Program Focus Fully delineate the extent of contamination regardless of risk. Delineate the extent of contamination based on a conservative 1 X 10-6 risk criteria. Reduces cost and time for data collection and subsequent agency review.
Consideration of Background Background is considered to be zero contamination unless determined on a site by site basis. Recognize elevated background levels may be natural to coal mining area. Handle evaluation in statistical manner. Addresses contamination from activities at the site.
Sampling Design All sampling conducted at once; phased sampling approach may be used on an exception basis. Phased sampling to allow iterative and innovative approaches (without formal EPA review) which support refinement of risk analysis. Allows a targeted decrease in uncertainty and time during data collection process and a faster cleanup.
Off-site Considerations Past, present and future impacts and current risks must be addressed even if not realistic. Address present impacts and current risks Places focus on current risks (which will be addressed) and not hypothetical future land uses.
Site Segmentation Separate the Site into Operable Units (OUs) and address each OU separately. Treat Site as a whole; only separate Site as appropriate based on data. Decreases EPA, WVDEP and Exxon administrative cost, and allows better integration of risk reduction and/or remediation options.
Quality Assurance Validate all data. Conduct Usability Assessment on all data. Reduces cost of Quality Assurance program while targeting value of data collected to site decisions.

Risk Assessment
ELEMENT
SUPERFUND APPROACH
XL PROPOSAL
BENEFIT
Level of Significant Risk Remediation generally required when risk level exceeds 1.0 x 10-6, unless negotiate to 1.0 x 10-4. Default to 1.0 x 10-4 as trigger for risk reduction or remediation; use 1.0 x 10-6 as trigger for screening and delineation only. Targets investment to controlling unacceptable risks; results in quicker cleanup due to decrease in negotiation time.
Toxicity and Exposure Data Source Only data in IRIS or Superfund Guidance can be used even if not most appropriate for Site. Allow use of alternative published data, the source of which is subject to review and approval by EPA. Ensures data applied to decision is most current appropriate data for Site.
ARARs Rely on generic ARARs even if no reduction in risk or benefit to community. Rely on relevant data and risk assessment-based criteria specific to the Site. Use of best scientific information will provide a more certain analysis.
Risk Reduction Focus on removal, and not risk reduction or exposure control. Could shift risks during transport and ultimate disposal of wastes. Focus on risk reduction and exposure control. Targets investment to risk control and not chemical removal and shifting of risk.
Model Selection and Parameterization Rely on standard, default models and parameters. Allow use of most relevant model and parameters for Site conditions. Use of best scientific information will provide a more certain analysis.
Receptor Selection Based on theoretical sensitive populations; includes residential scenario as a possibility even if not realistic. Calculate only realistic projected land use scenarios based on owner and community input, and zoning/deed restrictions. Prevent over-investment to control unrealistic risks.

Risk Assessment

ELEMENT
SUPERFUND APPROACH
XL PROPOSAL
BENEFITS
Ecological Risk Assessment Focus on protection of individual ecological receptors and not communities. Address protection of ecological receptors by focusing on current relevant populations, communities and habitats. Analysis would focus on high level of ecosystem integrity.
Bioavailability Risk Assessment Assumptions Default assumption typically assumes 100% bioavailability. Develop site-specific bioavailability data as needed. Use of best scientific information will provide a more certain analysis.
Point Source Concentration Assumptions Utilize current analytical values over entire exposure period even if values will change over time. Integrate average concentration over exposure period based on intrinsic degradation. Provides more accurate estimate of site specific potential exposure and risk.
FAIRMONT XL PROJECT
DESIRED REGULATORY FLEXIBILITIES
Feasibility Study
ELEMENT
SUPERFUND APPROACH
XL PROPOSAL
BENEFIT
Remedy Identification and Selection May require treatability testing of some remedies before implementation. Flexibility to focus on proven remedies early and implement without feasibility studies, testing, and reports. Earlier reduction in risk and decreased overall costs. Faster return of property to beneficial use.
Remedy Evaluation Evaluate all possible remedies. Screen only appropriate and cost-effective remedies, with input from EPA and WVDEP. Ensures applicability and cost-effectiveness of selected options.
Type of Remedial Solutions Statutory preference for permanent solutions (treatment or
removal).
Allow engineering or institutional controls to control contamination without shifting risk (removal). Increased flexibility to find adequate solutions. Faster cleanup time.
ARAR selection EPA and WVDEP identify, EPA controls selection, and all apply (regardless of whether they result in reduction risk or benefit to community). Exxon proposes relevant and appropriate ARARs or alternative targets. EPA (with WVDEP input) retains ultimate decision regarding what ARARs are relevant and appropriate. Provides continuity with risk assessment and allows stakeholders a role in deciding the adequate level of risk reduction at the Site. Focus investment on reduction of risk.
Hot Spot Elimination Requires full characterization of Site before remediation can begin. Allow application of presumptive remedies for hot spot areas without need for further characterization. (Confirmation sampling will be performed.) Decreases risks earlier in process, achieving greater exposure reductions in a shorter time. Decreases cost of site characterization.
No Further Action (NFA) Declarations Typically not formalized prior to final remedy selection. Grant accelerated NFA for non-process area of the site (i.e., hillside) or narrow focus of investigation to process areas. Reduces focus of site assessment and demonstrates progress to community.

Remedial Action
(Subject to RI Findings)
ELEMENT
SUPERFUND APPROACH
XL PROPOSAL
BENEFITS
Groundwater Evaluate all available remedial technologies and usage scenarios (regardless of whether realistic). Evaluate only realistic usage scenarios, including attenuation, and natural treatment. Targets investment on realistic and most probable risks.
Soils Look at each sample and Operable Unit individually. Look at site-wide averages and risk; if needed, treat very high concentrations as hot spots. Targets investment on realistic and most probable risks.
Surface Water Evaluate impacts from all chemicals regardless of source; eliminate sources even if removal is necessary to do so. Focus on water management to eliminate or minimize flow; remediate conditions that are attributed to this Site. Targets investment on realistic and most probable risks.
Buried Waste Requires buried waste to be removed even if little risk. Addresses all risks of buried waste; reduces risk associated with transport by managing in place. Eliminates risk of handling during removal and transport; avoids shifting risk to alternate community (disposal Site).
Buildings Determine if onsite buildings pose an unacceptable risk due to release of hazardous substances -- select action accordingly. Up front management of onsite physical hazards using OSHA standards for workers by demolition and proper disposal of building materials. Early demolition of buildings increases the aesthetic value to community and decreases risk to Site workers and unintended site visitors.
Quality Assurance Requires full construction plan and protocols regardless of applicability. Use standard industry practices without site specific requirements. Reduces cost of QA without a loss of ability to track work progress.
Safety OSHA plus additional requirements. OSHA requirements only. Lowers cost without impacting worker safety.

V. Administrative Order on Consent Critical Path

Exxon signed a CERCLA AOC with EPA to conduct a Remedial Investigation / Feasibility Study (RI/FS), and Risk Assessment for the Site in September, 1997. Under this AOC, Exxon committed to specific timeframes in which to submit an RI/FS Workplan. Based on the positive feedback from the XL pre-proposal scoping meetings discussed in Section IV.4. Project Selection Criteria -- Feasibility of this proposal, EPA has approved Exxon's request to submit a Workplan for only RI activities at this time. This RI Workplan was submitted to EPA Region III and WVDEP on March 31, 1998. As part of the RI Workplan, Exxon proposed a project schedule that included projected dates for submittal of the Risk Assessment and FS Workplans three months after EPA's approval of the RI Work Plan (based on an estimated EPA approval date of August 1, 1998, these Plans would be due in late October, 1998). Once approved by EPA, this schedule must be adhered to regardless of the status of the Project XL proposal. Therefore, Exxon has identified a project critical path of September 1, 1998 for a determination by EPA of acceptance or non-acceptance of this proposal under Project XL. This will allow Exxon, the EPA and WVDEP sufficient time to incorporate the desired regulatory flexibilities, outlined in Section IV.3. Project Selection Criteria -- Regulatory Flexibility of this proposal, into the prescribed project AOC schedule.

VI. Conclusion

Exxon believes that its proposal for an alternative, streamlined, cost-effective strategy for the investigation, risk assessment, remedy selection and remediation of the Site will meet EPA's goals for Project XL. The Project will result in superior environmental performance compared to that performed according to current Superfund regulations and guidelines, and at a substantially lower cost. Additionally, stakeholders will have a greater role in project development and implementation than traditionally practiced under Superfund.
