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

The Resource Conservation and Recovery Act (RCRA)

Answer

The Clean Air Act Title V permit program

Answer

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)

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

Improved process efficiency from recent capital investments

Answer

Successful implementation of the facility's P2 plan

Answer

Changes in how waste is classified under RCRA

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

Treating waste after it is generated to reduce toxicity

Answer

Recycling chemical by-products to recover economic value

Answer

Disposing of chemicals in the least hazardous manner

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

Whether the new solvent is listed on the RCRA F-list

Answer

Whether the new solvent requires a new NPDES permit

Answer

Whether the change triggers Title V air permitting for citrus terpenes

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

Process modification

Answer

Good operating practices

Answer

Input material substitution

Question 6

When conducting a waste minimization assessment, which tool helps quantify how much raw material enters a process versus how much leaves as product versus waste?

Accepted Answer

Material or mass balance analysis

Answer

Life Cycle Assessment (LCA)

Answer

Environmental Management System (EMS) audit

Answer

Risk-based corrective action (RBCA) framework

Question 7

A facility implements an ink-jet coding system to replace solvent-based stamping, eliminating 2,000 lbs/year of VOC waste. For TRI reporting purposes, this reduction would appear as a decrease in which column of the Form R?

Accepted Answer

Column for on-site releases to air

Answer

Column for off-site transfers for disposal

Answer

Column for on-site treatment before disposal

Answer

Column for quantities used for energy recovery
