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

Calculate the weight of hazardous waste shipped off-site for disposal in a given year

Answer

Determine financial liability for site contamination under CERCLA

Answer

Verify that manifest records match waste disposal invoices

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

Incineration of hazardous waste at a permitted facility to reduce its volume

Answer

Off-site recycling of spent solvents by a licensed reclaimer

Answer

Treatment of process wastewater to meet discharge permit limits

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

Requiring all waste to be returned to its original manufacturer for disposal

Answer

Mandating that generators transport their own waste to permitted disposal facilities

Answer

Eliminating the small quantity generator exemption for hazardous waste

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

Requiring proof of harm before restricting the use of a hazardous chemical

Answer

Applying conservative safety factors to exposure calculations for worker health standards

Answer

Defaulting to maximum treatment efficiency when discharge limits are unclear

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

Source reduction because it eliminates solvent purchases entirely

Answer

Treatment to reduce the toxicity of the solvent before reuse

Answer

Pollution control equivalent to installing end-of-pipe treatment

Question 6

An Environmental Management System (EMS) based on ISO 14001 supports pollution prevention most effectively through:

Accepted Answer

Establishing a Plan-Do-Check-Act cycle that drives continual improvement in environmental performance

Answer

Prescribing specific emission limits tailored to each facility's production output

Answer

Certifying that a facility has met all federal and state environmental permit requirements

Answer

Automating hazardous waste manifest preparation to reduce paperwork errors

Question 7

When conducting a pollution prevention opportunity assessment, which step should come first?

Accepted Answer

Gathering baseline data on material inputs, waste generation, and energy use

Answer

Selecting and implementing the lowest-cost control technology available

Answer

Submitting a voluntary reduction commitment to the EPA under a stewardship program

Answer

Hiring an outside consultant to identify Best Available Control Technology
