A facility's Title V permit contains an alternative operating scenario (AOS). What must the facility do before switching to the AOS?
Answer: Notify the permitting authority in advance as specified in the permit
Facilities may switch to a permit-approved AOS by notifying the permitting authority in advance as the permit specifies, without a formal revision.
What is the purpose of EPA's Compliance Assurance Monitoring (CAM) rule under 40 CFR Part 64?
Answer: To require monitoring sufficient to detect control equipment failures and permit deviations
CAM requires large sources using control devices to implement monitoring that can detect failures and ensure compliance.
During a Leak Detection and Repair (LDAR) inspection, a facility claims a component is 'unsafe to monitor.' What documentation must the facility maintain?
Answer: Written explanation of the safety hazard and an alternative monitoring schedule
Facilities must document the nature of the safety hazard in writing and follow an alternative monitoring schedule for unsafe-to-monitor components.
Which EPA program requires states to submit plans demonstrating how they will achieve and maintain compliance with NAAQS?
Answer: State Implementation Plans (SIPs)
States submit SIPs to EPA describing the regulatory measures they will use to attain and maintain NAAQS.
A stack test result shows emissions are 20% above the permit limit on the first test run but within limits on the second and third runs. How are the results typically evaluated?
Answer: The average of all three runs is compared to the limit
Performance test results are typically evaluated using the arithmetic mean (average) of all valid test runs.
What distinguishes a 'synthetic minor' source from a true minor source under air quality regulations?
Answer: A synthetic minor source has potential emissions above major source thresholds but is limited by permit conditions
Synthetic minor sources have potential-to-emit above major thresholds but accept legally enforceable permit limits to remain minor.
Under EPA Method 18, what type of air pollutants are typically measured?
Answer: Gaseous organic compounds using gas chromatography
Method 18 uses gas chromatography to measure gaseous organic compound concentrations in stack emissions.
