The estimated fair value of this facility declined in 2003 as a result of the expected reduc-
tion in MTBE demand due to enacted and anticipated federal and state bans of this gasoline
additive. The impairments in 2002 related to the shutdown of a polypropylene line at the
Company’s LaPorte, TX plant, an aniline and diphenylamine production facility in
Haverhill, OH, certain processing units at the Toledo refinery and a refined products pipe-
line and terminal owned by Sunoco Logistics Partners L.P. The chemical facilities and the
Toledo refinery processing units were shut down to eliminate less efficient production ca-
pacity, while the pipeline and terminal were idled because they became uneconomic to
operate. For a further discussion of these asset impairments, see Note 2 to the consolidated
financial statements.
Environmental Remediation Activities
Sunoco is subject to extensive and frequently changing federal, state and local laws and
regulations, including, but not limited to, those relating to the discharge of materials into
the environment or that otherwise relate to the protection of the environment, waste
management and the characteristics and composition of fuels. These laws and regulations
require environmental assessment and/or remediation efforts at many of Sunoco’s facilities
and at formerly owned or third-party sites.
Sunoco’s accrual for environmental remediation activities amounted to $148 million at
December 31, 2004. This accrual is for work at identified sites where an assessment has
indicated that cleanup costs are probable and reasonably estimable. The accrual is undis-
counted and is based on currently available information, estimated timing of remedial ac-
tions and related inflation assumptions, existing technology and presently enacted laws
and regulations. It is often extremely difficult to develop reasonable estimates of future site
remediation costs due to changing regulations, changing technologies and their associated
costs, and changes in the economic environment. In the above instances, if a range of
probable environmental cleanup costs exists for an identified site, FASB Interpretation No.
14, “Reasonable Estimation of the Amount of a Loss,” requires that the minimum of the
range be accrued unless some other point in the range is more likely, in which case the
most likely amount in the range is accrued. Engineering studies, historical experience and
other factors are used to identify and evaluate remediation alternatives and their related
costs in determining the estimated accruals for environmental remediation activities.
Losses attributable to unasserted claims are also reflected in the accruals to the extent they
are probable of occurrence and reasonably estimable.
Management believes it is reasonably possible (i.e., less than probable but greater than
remote) that additional environmental remediation losses will be incurred. At December
31, 2004, the aggregate of the estimated maximum additional reasonably possible losses,
which relate to numerous individual sites, totaled approximately $90 million. However,
the Company believes it is very unlikely that it will realize the maximum loss at every site.
Furthermore, the recognition of additional losses, if and when they might occur, would
likely extend over many years and, therefore, likely would not have a material impact on
the Company’s financial position.
Management believes that none of the current remediation locations, which are in various
stages of ongoing remediation, is individually material to Sunoco as its largest accrual for
any one Superfund site, operable unit or remediation area was less than $7 million at De-
cember 31, 2004. As a result, Sunoco’s exposure to adverse developments with respect to
any individual site is not expected to be material. However, if changes in environmental
regulations occur, such changes could impact several of Sunoco’s facilities and formerly
owned and third-party sites at the same time. As a result, from time to time, significant
charges against income for environmental remediation may occur.
Under various environmental laws, including the Resource Conservation and Recovery
Act (“RCRA”), Sunoco has initiated corrective remedial action at its facilities, formerly
