Question 1

Which greenhouse gas has the highest 100-year Global Warming Potential (GWP) among those commonly reported?

Accepted Answer

Sulfur hexafluoride (SF6)

Answer

SF6 has a 100-year GWP of approximately 23,500, far exceeding CO2 (1), CH4 (28), and N2O (265), making it the most potent common greenhouse gas by weight.

Question 2

Under the Clean Air Act's Prevention of Significant Deterioration (PSD) program, a major stationary source must undergo which review before construction?

Accepted Answer

Best Available Control Technology analysis

Answer

PSD permits require a Best Available Control Technology (BACT) analysis to ensure major new or modified sources use the most stringent feasible emission controls.

Question 3

An 'attainment area' that is redesignated due to worsening air quality becomes a 'maintenance area' under what plan requirement?

Accepted Answer

State Implementation Plan maintenance plan

Answer

Areas redesignated to attainment must develop a maintenance plan as part of the State Implementation Plan (SIP) to demonstrate continued compliance with NAAQS.

Question 4

Which pollutant is primarily responsible for stratospheric ozone depletion and is regulated under the Montreal Protocol?

Accepted Answer

Chlorofluorocarbons (CFCs)

Answer

CFCs release chlorine atoms in the stratosphere that catalytically destroy ozone molecules; the Montreal Protocol phases out their production and use globally.

Question 5

In air quality environmental review, the 'receptor' is best defined as:

Accepted Answer

A location or person potentially exposed to air pollutants

Answer

A receptor is a location—or the person/ecosystem at that location—where air pollutant concentrations are evaluated for potential health or environmental impacts.
