CEA Air Emission Monitoring & Control 5

Question 1

Which of the following describes the 'bubble concept' in air pollution control for existing sources?

Accepted Answer

Treating all emission points within a facility as a single source for compliance averaging purposes

Answer

The bubble concept allows a facility to treat all its emission stacks as one imaginary bubble, enabling emissions trading among units as long as total facility emissions stay within limits.

Question 2

What does a CEMS 'daily calibration drift check' assess?

Accepted Answer

Whether the analyzer's response to zero and span gases has shifted since the last calibration

Answer

The daily calibration drift check introduces zero and span reference gases to determine if the analyzer's response has drifted, ensuring ongoing measurement accuracy between full calibrations.

Question 3

An auditor discovers that a facility's Title V permit requires quarterly stack testing but only annual testing was conducted. This is an example of:

Accepted Answer

A monitoring deviation/violation that must be reported under the permit's deviation reporting requirements

Answer

Failure to conduct required monitoring at the specified frequency is a monitoring deviation, which must be reported to the permitting authority regardless of whether the emission measurements indicate compliance.

Question 4

What is the primary difference between 'Best Available Control Technology' (BACT) and 'Lowest Achievable Emission Rate' (LAER)?

Accepted Answer

BACT applies in attainment areas and allows energy/economic consideration; LAER applies in nonattainment areas without cost consideration

Answer

BACT applies under PSD (attainment areas) and allows consideration of energy, economic, and environmental impacts; LAER applies in nonattainment NSR and requires the most stringent rate achievable without cost consideration.

Question 5

Which parameter must be measured simultaneously with pollutant concentration when reporting emissions as a mass emission rate (lb/hr)?

Accepted Answer

Stack gas volumetric flow rate

Answer

Mass emission rate (lb/hr) is calculated by multiplying pollutant concentration (lb/dscf) by the stack gas volumetric flow rate (dscf/hr), so flow rate measurement is essential.
