Question 1

Which life cycle assessment (LCA) phase evaluates the environmental impact of raw material extraction for air pollution control equipment?

Accepted Answer

Cradle-to-gate

Answer

Cradle-to-gate assessment covers environmental impacts from raw material extraction through manufacturing, before the product leaves the factory.

Question 2

A facility installs variable frequency drives (VFDs) on exhaust fans. The primary air quality sustainability benefit is:

Accepted Answer

Reduced energy consumption lowering indirect emissions

Answer

VFDs reduce motor speed to match demand, cutting energy use and thereby reducing indirect emissions from power generation.

Question 3

Under EPA's Significant New Alternatives Policy (SNAP), refrigerant substitutes are evaluated primarily to:

Accepted Answer

Replace ozone-depleting substances with lower environmental impact options

Answer

SNAP identifies and evaluates alternatives to ozone-depleting substances, promoting substitutes that reduce stratospheric ozone depletion and climate impacts.

Question 4

A green building achieves LEED certification partly through indoor air quality credits. Which practice specifically contributes to IAQ credits?

Accepted Answer

Using low-VOC paints and adhesives during construction

Answer

Using low-VOC materials reduces off-gassing of volatile organic compounds, directly improving indoor air quality and earning LEED IAQ credits.

Question 5

The Clean Air Act's Title IV Acid Rain Program uses cap-and-trade for SO₂ primarily to:

Accepted Answer

Reduce total SO₂ emissions cost-effectively while allowing flexible compliance

Answer

Title IV's cap-and-trade system sets an aggregate SO₂ emissions cap, allowing sources to buy and sell allowances for cost-effective, flexible compliance.
