CPT Emissions Control & Environmental Compliance 2 — Questions and Answers
Question 1: Under the Clean Air Act, what is the primary purpose of a Title V operating permit?
- To authorize new facility construction
- To consolidate all air emission requirements into one enforceable document (Correct answer)
- To set national ambient air quality standards
- To regulate wastewater discharges
Correct answer: To consolidate all air emission requirements into one enforceable document
Title V permits consolidate all applicable air quality requirements for major sources into a single, federally enforceable operating permit.
Question 2: What does the term 'fugitive emissions' refer to in process facilities?
- Intentional venting during startup
- Emissions that escape from equipment leaks rather than through stacks (Correct answer)
- Emergency flare releases
- Permitted stack emissions
Correct answer: Emissions that escape from equipment leaks rather than through stacks
Fugitive emissions are unintentional releases from equipment components like valves, flanges, and pump seals rather than from designed emission points.
Question 3: A facility is classified as a 'major source' under the Clean Air Act if it emits at least how many tons per year of a criteria pollutant in an attainment area?
- 10 tons
- 50 tons
- 100 tons (Correct answer)
- 250 tons
Correct answer: 100 tons
In attainment areas, a stationary source emitting 100 tons per year or more of any criteria pollutant is classified as a major source.
Question 4: Which monitoring method requires process technicians to visually inspect equipment components for leaks using portable instruments?
- Continuous Emissions Monitoring (CEM)
- Leak Detection and Repair (LDAR) (Correct answer)
- Optical Remote Sensing (ORS)
- Stack sampling
Correct answer: Leak Detection and Repair (LDAR)
LDAR programs require technicians to use portable detectors to survey equipment components and repair leaks within specified timeframes.
Question 5: What is the purpose of a 'fence-line monitoring' program at a chemical facility?
- To monitor employee exposure inside the plant
- To track perimeter air concentrations affecting surrounding communities (Correct answer)
- To measure stack emissions at the source
- To calibrate continuous emission monitors
Correct answer: To track perimeter air concentrations affecting surrounding communities
Fence-line monitoring measures ambient air concentrations at the property boundary to assess potential community exposure from facility emissions.
Question 6: Under EPA regulations, a 'deviation' from permit conditions must typically be reported within what timeframe for a prompt deviation?
- 24 hours (Correct answer)
- 48 hours
- 7 days
- 30 days
Correct answer: 24 hours
Prompt deviations from permit conditions typically require verbal notification to the regulatory agency within 24 hours of discovery.
Question 7: Which EPA regulation specifically requires flares at refineries and chemical plants to meet specific combustion efficiency and visible emission standards?
- 40 CFR Part 60 Subpart A
- 40 CFR Part 63 MACT standards
- NSPS for petroleum refineries (40 CFR 60, Subpart J) (Correct answer)
- RCRA hazardous waste standards
Correct answer: NSPS for petroleum refineries (40 CFR 60, Subpart J)
The New Source Performance Standards for petroleum refineries under 40 CFR Part 60 Subpart J set specific performance requirements for flares.
