Waste Analyses for Auto Dealerships
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 TCLP Test
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
