Larger sized HDPE drums may be used as secondary containment measures when transporting
calomel. An example of this type of larger sized HDPE container is a 95-gallon “overpack”
drum, and is illustrated in Figure 22.1-6 below. Along with the aforementioned 55-gallon HDPE
drums, these containers may also be used as a means to collect hazardous waste when responding
to a spill.

22.1.2 Condition of Containers – 40 CFR 264.171
The condition of incoming containers will be evaluated as the shipment is unloaded from the
delivery truck. Containers will be checked for dents, leaks, or defects. Management practices
will require containers to remain closed during the visual evaluation. Containers in good
condition will be staged and transferred to the appropriate storage area within the plant spaces.
Refer to Section 1.2.1 for a detailed description of procedures in the event a breached container
is received at the proposed TSF.
22.1.3 Empty Containers – 40 CFR 261.7(b)
After the content of a container is emptied, the container will be rinsed to meet the definition of a
RCRA empty container. RCRA empty containers may be reused, at the discretion of the
proposed TSF’s Manager to contain the same type of waste.
Containers used to transport and store spent activated carbon (i.e., 55-gallon steel drums) can be
placed in the retort to remove any residual mercury and crushed to optimize storage space. They
