AQS Compliance Reporting & Documentation 5

Question 1

A facility operating a boiler subject to 40 CFR Part 63 Subpart DDDDD (Major Source Boiler MACT) must conduct a tune-up every two years. What must be documented as part of each tune-up?

Accepted Answer

Tune-up procedures performed, CO and O2 measurements, and fuel usage during the tune-up period

Answer

Subpart DDDDD tune-up records must document the specific procedures followed, combustion measurements taken, and adjustments made to demonstrate compliance with the work practice standard.

Question 2

Under EPA regulations, what is the definition of 'emission averaging' in the context of NESHAP compliance?

Accepted Answer

Using lower emissions from one unit to offset higher emissions from another unit within the same facility

Answer

Emission averaging allows a facility to average emission rates across multiple emission points, permitting one unit to exceed limits if another unit compensates with lower emissions.

Question 3

Which section of the Clean Air Act grants EPA the authority to impose civil penalties up to $70,117 per day per violation for air quality violations (as adjusted for inflation)?

Accepted Answer

Section 113

Answer

CAA Section 113 authorizes EPA to assess civil administrative and judicial penalties for violations of the Act, with per-day-per-violation penalty amounts subject to inflation adjustments.

Question 4

A facility's Title V permit requires parametric monitoring of a regenerative thermal oxidizer (RTO). Which parameter is most commonly specified as the key indicator of RTO performance?

Accepted Answer

Combustion chamber temperature

Answer

RTO combustion chamber temperature is the primary surrogate parameter because adequate temperature (typically ≥1,600°F) is the best indicator of proper VOC destruction efficiency.

Question 5

When submitting electronic reports through EPA's Compliance and Emissions Data Reporting Interface (CEDRI), what must a responsible official provide to validate the submission?

Accepted Answer

An electronic signature using EPA's Central Data Exchange (CDX) account credentials

Answer

EPA's CEDRI requires submitters to use CDX electronic signature agreements (ESA) to authenticate and legally bind the responsible official to the accuracy of the report.
