Subject: RE: Bayshore Ponds Remediation
' Brian,
I work for Walter and have been assigned this project. I quickly
' reviewed the status report you sent and wanted to get back to you with
my initial thoughts regarding your proposed excavation and disposal of
the "homogenized" slurry. We can talk after you get a chance to read
this.
Based on the data in the report, it appears that the homogenized
' slurry
is not nonhazardous, and therefore we cannot approve of the proposed
disposal at a landfill as solid waste. The analytical data in your
report shows that this would be hazardous waste and must be managed
and
disposed in accordance with applicable CHWRs. All samples in Table 1
' that were analyzed for TCLP exceeded the TCLP limit for benzene of 0.5
mg/1. These results also show that the 20X rule does not hold up for
characterizing this waste and in the future all waste characterization
samples must be run for TCLP analysis (for example, sample SHT
' (22+50)
in Table 1 contained 0.42 mg/kg benzene by total analysis, but this
sample also had a TCLP concentration of 0.72 mg/1, exceeding the
limit).
The waste characterization samples also need to be run for
ignitability
' if there are free liquids present.
