CPWM - Certified Professional in Waste Management Waste Characterization and Classification Questions and Answers

Question 1

A solid waste is determined to be a RCRA characteristic hazardous waste if it exhibits which of the following properties?

Accepted Answer

Ignitability, corrosivity, reactivity, or toxicity

Answer

According to the EPA under the Resource Conservation and Recovery Act (RCRA), a solid waste is classified as a characteristic hazardous waste if it demonstrates at least one of four specific characteristics: ignitability, corrosivity, reactivity, or toxicity.

Question 2

A waste management facility receives a shipment of industrial sludge. A test reveals the sludge is an aqueous solution with a pH of 1.5. How should this waste be classified?

Accepted Answer

As a corrosive hazardous waste (D002)

Answer

The EPA defines corrosive hazardous wastes as aqueous wastes with a pH less than or equal to 2, or greater than or equal to 12.5. Since the sludge has a pH of 1.5, it meets the criteria for corrosivity and is assigned the EPA waste code D002.

Question 3

Which of the following is a primary goal of the EPA's Universal Waste Program?

Accepted Answer

To encourage the collection and recycling of certain common hazardous wastes

Answer

The Universal Waste Program streamlines hazardous waste management standards for certain commonly generated hazardous wastes, like batteries and pesticides, to promote their collection and recycling and ease the regulatory burden on generators.

Question 4

When conducting a municipal solid waste (MSW) characterization study, the 'quartering' method is a technique used for what purpose?

Accepted Answer

Obtaining a representative, smaller sample from a larger, mixed waste pile

Answer

Quartering is a common sampling method in waste characterization where a larger pile of waste is thoroughly mixed, divided into four equal sections, and two diagonally opposite sections are discarded. The remaining two sections are remixed, and the process is repeated until a manageable, representative sample size is achieved.

Question 5

A manufacturing facility generates a waste stream that is not explicitly on an F, K, P, or U list. What is the generator's next critical step in the hazardous waste determination process?

Accepted Answer

Determine if the waste exhibits one of the four characteristics of hazardous waste

Answer

The hazardous waste determination process requires the generator to first check if the waste is a listed waste. If it is not, the generator must then determine if the waste exhibits any of the four hazardous characteristics: ignitability, corrosivity, reactivity, or toxicity.
