Sampling Containerized Waste
The term “container” refers to receptacles designed for transporting materials (e.g., drums,
flasks, and pigs). Sampling devices include Composite Liquid Waste Samplers (COLIWASAs),
tubes, trowel, drum thieves, and tube samplers.
Sampling of Tanks
A representative sample of the waste will be collected from the side or bottom of each tank.
Samples will be collected such that various depths in the tank will be evaluated if the
material phase separates or contains multiple batches. Multiple grab samples may be
composited to obtain a weighted representation of the tank contents. Sampling SOPs for
each process tank will be developed and reviewed by the laboratory staff when necessary.
Frozen Waste
The proposed TSF will not sample waste that is frozen. The waste will be held in the truck
unloading area until the waste can be sampled. A sample will then be collected as outlined
in this section.
2.7 Waste Characterization & Frequency of Analysis – 40 CFR 270.14(b)(2)
& 264.13(b)(4)
Waste characterization data can be found in Appendix 2-E.
2.7.1 Routine Wastes
Process Wastes
The processes at the proposed TSF will generate a number of routine waste streams. These waste
streams will be evaluated initially at the beginning of operations and annually updated to verify
accuracy. The waste characterization will also be re-evaluated whenever the process that
generated the waste changes or there is an unresolved discrepancy on a shipment.
Elemental Mercury
The chemical composition of the recovered elemental mercury is well known and consistent. As
discussed above, the proposed TSF will use waste generator knowledge to characterize this
material. Elemental mercury purity will be evaluated based on weight. While these waste streams
will not be routinely analyzed prior to being stored, the proposed TSF will review all waste
streams on an annual basis or any time the waste generating process changes.
Calomel
The chemical composition of the calomel is well known and is within the process design range.
As discussed above, the proposed TSF will use waste generator knowledge to characterize this
material. While this waste stream will not be routinely analyzed prior to being treated, the
proposed TSF will review all waste streams on an annual basis or any time the waste generating
process changes.
