CEA Pollution Prevention & Waste Minimization 3

Question 1

Which federal law requires large manufacturers to report annual releases and transfers of listed toxic chemicals, providing key data for P2 benchmarking?

Accepted Answer

The Emergency Planning and Community Right-to-Know Act (EPCRA) Section 313

Answer

EPCRA Section 313 requires facilities meeting certain thresholds to submit annual Toxics Release Inventory (TRI) reports, which are widely used to track pollution prevention progress.

Question 2

An auditor calculates that a facility's waste-to-product ratio has increased from 0.05 to 0.12 over three years despite a stable production volume. This trend most likely indicates:

Accepted Answer

Deteriorating process performance or product formulation changes

Answer

A rising waste-to-product ratio with stable production means more waste is being generated per unit of product, indicating declining process efficiency or product/process changes that increase waste.

Question 3

Green chemistry Principle #1, 'Prevention,' is most aligned with which pollution management strategy?

Accepted Answer

Designing chemical processes that generate no waste

Answer

Green chemistry's first principle states it is better to prevent waste than to treat or clean it up after formation, directly aligning with the concept of source reduction.

Question 4

A facility substitutes a chlorinated solvent (TCE) with a bio-based citrus solvent for parts cleaning. Which life-cycle consideration is MOST important for the auditor to evaluate?

Accepted Answer

Whether the new solvent's full life-cycle impacts, including production and disposal, are lower

Answer

A true P2 assessment requires evaluating full life-cycle impacts; a substitute may appear greener in use but could have significant upstream production or downstream disposal burdens that offset benefits.

Question 5

Which type of P2 technique involves redesigning a product so it uses less hazardous materials, lasts longer, or can be more easily disassembled for recycling?

Accepted Answer

Product reformulation or design for environment (DfE)

Answer

Design for Environment (DfE) and product reformulation focus on changing the product itself — its composition, durability, or end-of-life characteristics — to reduce environmental impacts throughout the product's life cycle.
