What are the regulatory levels for waste characterization purpose?
Waste characterization is a complicated issue as there are several different tests currently performed in order to determine if your waste is “hazardous” or “non-hazardous.” The following decision tree has been provided as a general guideline. • Take a minimum of four (4) representative samples (200 grams/8 ounces) of each segmented waste stream. • Request a Total Threshold Limit Concentration (TTLC) test. • If the results of the TTLC are less than 50 ppm, the waste is not hazardous per California Standard.
