Question 1: Under the Clean Air Act, which permit program applies to major sources of air pollutants that are newly constructed or significantly modified?
- New Source Review (NSR) (Correct answer)
- Title V Operating Permit
- General Permit
- Minor Source Permit
Correct answer: New Source Review (NSR)
New Source Review is the preconstruction permitting program under the Clean Air Act that applies to new or modified major stationary sources.
Question 2: What does the term 'fugitive emissions' refer to in air quality compliance?
- Emissions that escape from equipment leaks, valves, or seals rather than through a stack or vent (Correct answer)
- Emissions released during emergency shutdowns only
- Emissions from mobile sources on facility property
- Emissions that exceed permitted levels during normal operations
Correct answer: Emissions that escape from equipment leaks, valves, or seals rather than through a stack or vent
Fugitive emissions are pollutants that escape to the atmosphere through leaks in equipment such as valves, flanges, pumps, and seals rather than being released through a designated stack or vent.
Question 3: Which federal regulation establishes National Emission Standards for Hazardous Air Pollutants (NESHAP)?
- 40 CFR Part 63 (Correct answer)
- 40 CFR Part 60
- 40 CFR Part 70
- 40 CFR Part 51
Correct answer: 40 CFR Part 63
40 CFR Part 63 contains the National Emission Standards for Hazardous Air Pollutants, which regulate emissions of hazardous air pollutants from specific source categories.
Question 4: During a compliance inspection, an inspector discovers that a facility's Continuous Emissions Monitoring System (CEMS) has been offline for 48 hours without notification. What is the most significant compliance concern?
- The facility may be violating its reporting and monitoring requirements under its operating permit (Correct answer)
- The facility automatically loses its operating permit
- The EPA must immediately shut down the facility
- The facility must replace the entire CEMS unit within 24 hours
Correct answer: The facility may be violating its reporting and monitoring requirements under its operating permit
Operating permits require facilities to maintain and operate CEMS and report any monitoring system downtime, so extended unreported outages constitute a permit violation.
Question 5: What is the primary purpose of a Risk Management Plan (RMP) under Section 112(r) of the Clean Air Act?
- To prevent accidental releases of extremely hazardous substances and minimize consequences if a release occurs (Correct answer)
- To calculate annual emission fees for Title V permits
- To establish maximum achievable control technology standards
- To determine attainment status for criteria pollutants
Correct answer: To prevent accidental releases of extremely hazardous substances and minimize consequences if a release occurs
Risk Management Plans are required to prevent accidental releases of listed extremely hazardous substances and to detail emergency response procedures if releases occur.
Question 6: Which of the following best describes the concept of 'lowest achievable emission rate' (LAER)?
- The most stringent emission limitation achieved in practice by any source in the same category, regardless of cost (Correct answer)
- The emission rate that balances cost-effectiveness with environmental protection
- The average emission rate across all similar facilities in the region
- The emission rate set by the state implementation plan for existing sources
Correct answer: The most stringent emission limitation achieved in practice by any source in the same category, regardless of cost
LAER is the most stringent emission limitation achieved in practice by any similar source and applies to new major sources in nonattainment areas without considering cost.
