3. Hazardous Waste Determination: Complete the following to demonstrate that the residuals are non -hazardous under
RCRA: (Note - this item does not have to be completed for facilities that are less than 0.5 MGD in design flow that treat
100% non -municipal, domestic wastewater only)
a. Are the residuals listed in 40 CFR §261.31-§261.33: ❑ yes Z no.
If yes, list the number(s):
b. Specify whether or not the residuals exhibit any of the characteristics defined by 40 CFR §261.21-
261.24: ❑ yes Z no.
Fill in the following tables with the results of the latest toxicity characteristic leaching procedure (TCLP) analysis as
well as those for corrosivity, ignitability, and reactivity:
Laboratory: Environmental Chemists. Inc. and Date of analysis: 12/7/22
Passed corrosivity test: 0 yes ❑ no. pH: s.u. (2 <pH < 12.5)
Passed ignitability test: 0 yes ❑ no. Flashpoint: >157 OF (> 140°F)
Passed reactivity test: ❑ yes ❑no. HCN: <1.0 mg/kg (<250) & HaS: 0.20 mg/kg (<500)
