Potential Remediation Obligations As of December 31, 2008, Sunoco has been named as a potentially responsible party (PRP) at 42 sites identified or potentially identifiable as Superfund sites under the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). In addition, under RCRA and related state laws, Sunoco has potential remediation obligations for its current facilities, including refineries, service stations, terminals, pipelines and truck transportation facilities, as well as formerly owned sites at which contamination generated by Sunoco may be located. As of December 31, 2008, Sunoco’s accrued liability for probable and reasonably estimable remediation activities was $123 million.

Since 2001, the total active site portfolio for Retail Marketing has been reduced by 25% through improved remediation efforts including utilization of new technology such as chemical oxidation, modeling and enhanced remediation system design and performance.
Focus on further reducing the total site portfolio will continue and Retail Marketing initiatives, including environmental equipment capital upgrades and operational improvements, will continue to prevent contamination.
New sites are identified primarily from divestment activity and other work that discover evidence of past releases.
Marketing’s success in reducing its overall site portfolio has been realized despite unprecedented real estate divestment activity in the last 5 years and continually tightening regulatory requirements that make site closures more difficult to obtain.
UST Regulations Primarily as a result of the 2005 Energy Policy Act, many states began revising their underground storage tank regulations in 2007. Sunoco has been monitoring these regulations closely to assure it is consistent with its stringent design and operating standards and in some cases has provided comments to ensure the regulations are practicable.
