for Auto Dealerships
The
Waste Analyses for Auto Dealerships project conducted TCLP analysis on used
antifreeze, used oil absorbent, and floor drain sump sludge at 1) The study did not support a generalized statement
that automotive dealerships should no longer make a hazardous waste
determination through TCLP analysis on these wastes. Some toxins were present
in each of the waste streams. 2) Overall the study identified that
shops that continue to use chlorinated brake cleaner have the potential to
generate waste that is toxic due to the presence of Tetrachloroethene at levels
above the 0.7 milligrams per Liter (mg/L) regulatory threshold in antifreeze
and sump sludge. 3) Antifreeze samples can show erroneous TCLP test results for
Arsenic and Selenium when using the traditionally TCLP methodology. Using the
Graphite Furnace procedure is the most reliable TCLP analytical method for
antifreeze. See summary at Requesting

Antifreeze
Heavy Metal Data Sheet 56 Wastes that have the potential to be a hazardous, due to the presence
of toxins, require the TCLP testing protocol to determine whether the waste is
hazardous or non-hazardous. These rules are part of the federal regulations for
hazardous waste management. In Recommendations for Antifreeze See subsequent posting for a brief data summary. Go easy on me Gang, I spent two years working on this…… Sue Sue Schauls Program Manager 319/273-6592 (direct line) 319/273-8905 (office) |
