Covering the area between the Tank Farm and the
western perimeter road (Figure 5-1), the Tank Farm Buffer Area was
created by the infilling of the eastern shoreline of Muggah Creek
with Blast Furnace slag in the early 20th century (Figure 5-2).
This area is home to many pipelines, as well as the bunker ‘C’
pump house. Fuel lines traversing this area include those between
the docks and the Tank Farm, and the Tank Farm and the Open Hearth
and Reheat Furnace. The pipeline for the Tar Ponds Incinerator also
crosses this area. No earlier structures are known to have been
located in this area.
The Bunker ‘C’ Pump House is constructed of a combination
of reinforced concrete, brick, steel and wood. The structure houses
mechanical fuel pumping equipment and underground fuel distribution
lines. The roof is constructed of a suspected asbestos roof material
referred to as transite.
Visible free product was observed within the piping trench and
the floor of the Bunker ‘C’ Pump House was heavily stained
with petroleum hydrocarbon. Significant petroleum hydrocarbon impacted
soil and groundwater is expected under the building and adjacent
to the underground piping.
|The majority of open space in this
area is covered with granular materials. Slopes at certain locations
show signs of surface erosion. Overland drainage in the area
may present the possibility of siltation and sediment impacts
to receiving waters.
