  1. Under Title V of the Clean Air Act, which facilities are required to obtain an operating permit?

    Answer: Major sources emitting above threshold quantities of regulated pollutants

    Title V requires major stationary sources—those emitting above specific threshold quantities (e.g., 100 tons/year of a regulated pollutant)—to obtain a comprehensive operating permit.

  2. Photochemical smog formation requires the presence of which two primary precursor pollutants reacting in sunlight?

    Answer: NOx and volatile organic compounds (VOCs)

    Ground-level ozone (photochemical smog) forms when NOx and VOCs react in the presence of sunlight, creating a secondary pollutant harmful to human health.

  3. An environmental planner conducting an air quality conformity determination must verify that transportation plans comply with which standard?

    Answer: National Ambient Air Quality Standards via the Clean Air Act transportation conformity rule

    Transportation conformity under the Clean Air Act requires that federally funded transportation plans and projects not cause or worsen violations of NAAQS in nonattainment and maintenance areas.

  4. Which term describes the process by which SO2 and NOx emissions transform into acid rain in the atmosphere?

    Answer: Wet and dry deposition

    SO2 and NOx undergo atmospheric oxidation to form sulfuric and nitric acids, which return to Earth as wet deposition (acid rain) or dry deposition onto surfaces.

  5. The U.S. EPA's Toxic Release Inventory (TRI) program, established under EPCRA Section 313, requires facilities to report:

    Answer: Annual releases and transfers of listed toxic chemicals above threshold quantities

    TRI requires facilities in covered industrial sectors to annually report releases and off-site transfers of over 600 listed toxic chemicals that exceed reporting thresholds.

  6. Which atmospheric stability class (Pasquill-Gifford) represents the most unstable conditions for pollutant dispersion?

    Answer: Class A

    Pasquill-Gifford Class A represents extremely unstable atmospheric conditions with strong daytime solar radiation, promoting rapid vertical mixing and dilution of pollutants.
