Section 725
Section 725.352Â Waste
Analysis
a)Â Â Â Â Â Â Â Â In addition to the waste analyses required by Section 725.113,
the owner or operator must analyze a representative sample of waste from each
incoming movement before adding the waste to any existing pile unless either of
the following conditions is fulfilled:
1)Â Â Â Â Â Â Â Â The only wastes the facility receives that are amenable to
piling are compatible with each other, or
2)Â Â Â Â Â Â Â Â The waste received is compatible with the waste in the pile to
which it is to be added.
b)        The analysis conducted must be capable of differentiating
between the types of hazardous waste the owner or operator places in piles, so
that mixing of incompatible waste does not inadvertently occur. The analysis
must include a visual comparison of color and texture.
BOARD NOTE:Â As required by Section 725.113, the waste
analysis plan must include analyses needed to comply with Sections 725.356 and
725.357. As required by Section 725.173, the owner or operator must place the
results of this analysis in the operating record of the facility.
