Sunoco, Inc - Marcus Hook
Refinery
Marcus Hook, Pennsylvania

The Road to Reuse
~~~
In Marcus Hook, Pennsylvania,
the oil refinery operations
continue on 767 acres of the
Sunoco Marcus Hook Refinery
site. The facility is located on
approximately 788 acres along
the Delaware River in Marcus
Hook, Pennsylvania. The
refinery is generally divided
into two types of areas: refining
and processing activities and
crude oil and product storage.
Utilizati on of the refinery has
a long history of petroleum
transportation, storage, and
processing.
The facility holds an EPA
RCRA operating permit for a
hazardous waste storage area.
A non-aqueous phase liquid
(NAPL) was confirmed in the
groundwater at the facility. A
Comprehensive Remedial Plan
(CRP) was prepared in response
to a request by the Pennsylvania
Department of Environmental
Protection (PADEP). The goals
of the CRP were: (1) to fully
Approximate total acres

Approximate Acres in Reuse:

identify the extent of the NAPL
plume, and (2) to prevent the
NAPL plume migration beyond
the property boundaries at
the Facility by implementing
hydraulic control of the water
table aquifer and NAPL
recovery.
The facility has implemented
the corrective measures such
as installation of additional
monitoring wells and recovery
system to prevent the migration
of NAPL beyond the perimeter
to the Delaware River. These
remedial activities are classified
by EPA as corrective action
stabilization activities.
In 2000, Sunoco and Florida
Power and Light negotiated the
construction of a 744-megawatt
combined-cycle, co-generation,
natural gas fired power plant
on the Phillips Island portion
of the facility (about 21 acres).
The co-generation plant uses
natural gas as a fuel source. This
reduces the number of boilers in
use at the refinery and reduces
the overall nitrogen oxide
(NOx) and sulfur oxide (SOx)
emissions. Sunoco performed a
site characterization, remedial
investigation and risk assessment
and developed a cleanup plan
for the Phillips Island site at the
facility. The co-generation plant
construction was completed
and ready for use in November
2004.
