What does 'Prevention of Significant Deterioration' (PSD) permitting apply to?
Answer: New major sources or major modifications in attainment areas
PSD permitting applies to new major stationary sources or major modifications at existing sources located in areas that meet national ambient air quality standards.
In a Continuous Emissions Monitoring System (CEMS), what is the purpose of a quarterly RATA (Relative Accuracy Test Audit)?
Answer: To verify CEMS accuracy against reference method measurements
A RATA compares CEMS readings against simultaneous EPA reference method stack tests to ensure the monitor is measuring emissions accurately.
Which greenhouse gas reporting threshold requires a facility to report annually to EPA under 40 CFR Part 98?
Answer: 25,000 metric tons CO2e per year
Facilities that emit 25,000 metric tons or more of CO2 equivalent per year must report greenhouse gas emissions annually to EPA under the mandatory GHG reporting rule.
What is a 'malfunction' exemption under the Clean Air Act, and what is its current legal status?
Answer: An exemption for excess emissions during equipment failures, struck down by courts
The SSM (Startup, Shutdown, Malfunction) exemption that allowed excess emissions during equipment malfunctions was struck down by the D.C. Circuit Court, and facilities must now comply during these events.
When using an infrared camera for optical gas imaging (OGI), what is the primary advantage over traditional Method 21 leak detection?
Answer: OGI can detect leaks faster and visualize emission plumes without contact
OGI cameras allow technicians to visually see gas plumes and rapidly survey large numbers of components without physically touching each one.
Under the Clean Air Act Section 112, what is a 'synthetic minor' source?
Answer: A source that accepts permit limits to stay below major source thresholds
A synthetic minor source is one that voluntarily accepts enforceable permit conditions to limit its potential to emit below major source thresholds, avoiding MACT requirements.
What environmental regulation requires facilities to prepare a Risk Management Plan (RMP) for extremely hazardous substances?
Answer: Clean Air Act Section 112(r)
Clean Air Act Section 112(r) requires facilities that handle threshold quantities of listed regulated substances to develop and submit an RMP to EPA.
