mercury storage area will be able to store 1,024 pigs (approximately 19,456 gallons of elemental
mercury).
13.4.4 Maximum Stored Calomel and Carbon
Calomel
As shown in the building floor plan design in Appendix 1-A, drawing H340940-0000-50-042-
0001, a dedicated calomel storage area has been incorporated into the design of the proposed
TSF Building. The maximum number of 55-gallon calomel drums that can be stored in this area
is 76.
However, the FSSMP may allow drums of calomel to be stored in other storage areas within
building envelope of the proposed TSF Building. Assuming a minimal inventory of other stored
hazardous waste (i.e., 16 pigs of elemental mercury and four 55-gallon drums of spent activated
carbon), the maximum foreseeable number of 55-gallon calomel drums to be stored within the
building envelope of the proposed TSF Building should not exceed 330.
Spent Activated Carbon
As shown in the building floor plan design in Appendix 1-A, drawing H340940-0000-50-042-
0001, a dedicated spent activated carbon storage area has been incorporated into the design of the
proposed TSF Building. The maximum number of 55-gallon drums of activated carbon that can
be stored in this area is 60.
However, the FSSMP may allow drums of spent activated carbon to be stored in other storage
areas within building envelope of the proposed TSF Building. Assuming a minimal inventory of
other stored hazardous waste (i.e., 16 pigs of elemental mercury and four 55-gallon drums of
calomel), the maximum foreseeable number of 55-gallon drums of spent activated carbon to be
stored within the building envelope of the proposed TSF Building should not exceed 346.
13.4.5 Methods for Removing, Transporting, Treating, Storing and Disposing
The treatment systems will be dismantled and removed from the service area. Foundations and
structural supports will be demolished. Heavy equipment will be used to demolish the proposed
TSF. Covered dump trucks will transport demolition debris to an appropriate landfill for
disposal. Wastewater will be transported using the tanker trucks similar to those that will be
contracted to transport water during the life of the proposed TSF.
Disposal of debris will occur as the demolition progresses. The staged removal of demolition
debris will minimize the volume of debris at any time during closure. Regular shipments of
accumulated waste and debris will minimize the area that can potentially be impacted by
demolition activities.
