CEI Air Quality Management 1 ā Questions and Answers
Question 1: Which is the primary federal law governing air quality and emissions in the United States?
- Safe Drinking Water Act
- Resource Conservation and Recovery Act
- Clean Air Act (Correct answer)
- Clean Water Act
Correct answer: Clean Air Act
The Clean Air Act is the primary federal law regulating air quality and emissions in the United States, first enacted in 1963 and significantly amended in 1970 and 1990.
Question 2: National Ambient Air Quality Standards (NAAQS) are primarily designed to protect what?
- Agricultural land productivity
- Military installation air quality
- Public health and welfare (Correct answer)
- Industrial production efficiency
Correct answer: Public health and welfare
NAAQS set by the EPA include primary standards to protect public health and secondary standards to protect public welfare, including visibility and ecosystems.
Question 3: Which of the following is classified as a criteria air pollutant under the Clean Air Act?
- Radon
- Particulate matter (PM2.5) (Correct answer)
- Mercury
- Dioxins
Correct answer: Particulate matter (PM2.5)
PM2.5 is one of the six criteria air pollutantsāincluding ozone, CO, NOx, SO2, and leadāfor which EPA has established NAAQS.
Question 4: A Prevention of Significant Deterioration (PSD) permit is required for which type of source?
- Stormwater discharges from industrial sites
- Underground storage tank installations
- Soil remediation activities at contaminated sites
- Major new or modified stationary sources in attainment areas (Correct answer)
Correct answer: Major new or modified stationary sources in attainment areas
PSD permits are required for major new or significantly modified stationary sources in areas already meeting NAAQS to prevent further deterioration of air quality.
Question 5: What is the primary purpose of an air dispersion model used by environmental inspectors?
- Calculate emission fees for a facility
- Measure actual pollutant concentrations at receptor sites
- Predict how pollutants spread and dilute in the atmosphere (Correct answer)
- Determine allowable stack height by regulation
Correct answer: Predict how pollutants spread and dilute in the atmosphere
Air dispersion models are mathematical tools used to predict the transport, dispersion, and transformation of pollutants in the atmosphere, helping regulators assess potential air quality impacts.
Question 6: Title V of the Clean Air Act requires which type of permit for major stationary sources?
- Water discharge permits for major facilities
- Transportation permits for hazardous material carriers
- Operating permits for major stationary sources (Correct answer)
- Construction permits for all new facilities
Correct answer: Operating permits for major stationary sources
Title V established a comprehensive operating permit program for major stationary sources, consolidating all applicable Clean Air Act requirements into a single permit document.
Question 7: A geographic area that does not meet NAAQS for one or more criteria pollutants is designated as what?
- Variance zone
- Prevention area
- Attainment area
- Non-attainment area (Correct answer)
Correct answer: Non-attainment area
A non-attainment area is a geographic area that does not meet the NAAQS for one or more criteria pollutants and is subject to more stringent regulatory requirements.
