Question 2

A waste stream has a pH of 2.5. Under RCRA, this waste would be classified as hazardous due to which characteristic?

Accepted Answer

Corrosivity

Answer

Corrosivity applies to aqueous wastes with pH ≤ 2 or ≥ 12.5, or liquids that corrode steel at a specified rate, per 40 CFR 261.22.

Question 3

Which EPA waste code series (F-codes) applies to non-specific source hazardous wastes from common industrial processes?

Accepted Answer

F-list wastes

Answer

F-list wastes (40 CFR 261.31) are hazardous wastes from non-specific sources such as solvent use and electroplating operations.

Question 4

What is the primary purpose of a Toxicity Characteristic Leaching Procedure (TCLP) test?

Accepted Answer

Simulate leaching of contaminants into groundwater from a landfill

Answer

TCLP simulates acidic leachate conditions in a co-disposal landfill to evaluate whether contaminants could migrate to groundwater.

Question 5

Which of the following is a P-listed (acutely hazardous) waste under RCRA?

Accepted Answer
