CHMM Pollution Prevention and Sustainability 3

Question 1

A facility conducting a P2 assessment uses a 'material balance' analysis. The primary purpose of this tool is to:

Accepted Answer

Account for all material inputs, products, and waste streams to identify inefficiencies and loss points

Answer

A material balance tracks all inputs and outputs of a process to identify where material is lost as waste, providing the data foundation for pollution prevention opportunities.

Question 2

Which of the following activities falls within the scope of the Pollution Prevention Act's definition of 'pollution prevention'?

Accepted Answer

Reduction in energy use that results in decreased air emissions per unit of production

Answer

Energy efficiency improvements that directly reduce emissions are considered source reduction under the Pollution Prevention Act when they prevent pollution from being generated.

Question 3

The 'cradle-to-grave' responsibility concept under RCRA most directly supports pollution prevention by:

Accepted Answer

Encouraging generators to minimize waste production to reduce ongoing liability

Answer

Because RCRA imposes perpetual liability on generators for their waste, minimizing waste generation through pollution prevention directly reduces the generator's legal and financial exposure.

Question 4

Which of the following best describes the 'precautionary principle' as applied in pollution prevention?

Accepted Answer

Taking preventive action to protect human health and the environment when scientific evidence of harm is uncertain

Answer

The precautionary principle holds that lack of full scientific certainty is not a reason to postpone protective measures when there is a risk of serious or irreversible harm.

Question 5

A CHMM is evaluating whether to implement a closed-loop solvent recovery system. From a pollution prevention standpoint, this is classified as:

Accepted Answer

Recycling — preferred over disposal but below source reduction in the P2 hierarchy

Answer

Closed-loop solvent recovery is an on-site recycling activity, which is preferable to disposal but ranks below true source reduction (eliminating solvent use) in the EPA's P2 hierarchy.
