CHA Emissions Control & Environmental Compliance 3

Question 1

Under the National Emission Standards for Hazardous Air Pollutants (NESHAP), which term describes a facility that emits 10 tons/year of a single HAP or 25 tons/year of combined HAPs?

Accepted Answer

Major source

Answer

A major source under NESHAP is defined as emitting 10 tons/year of any single HAP or 25 tons/year of total HAPs.

Question 2

Which control strategy hierarchy is EPA's preferred approach when addressing air emissions from industrial processes?

Accepted Answer

Prevention → Control → Treatment

Answer

EPA follows a pollution prevention hierarchy: prevent emissions at the source first, then control and treat what cannot be prevented.

Question 3

What is the purpose of a 'synthetic minor' operating permit condition?

Accepted Answer

Voluntarily limit emissions to stay below major source thresholds and avoid Title V

Answer

Synthetic minor conditions impose enforceable limits that keep actual emissions below major source thresholds, avoiding Title V requirements.

Question 4

During an audit, a boiler operating permit lists a NOx limit of 0.10 lb/MMBtu. Which parameter must be tracked to demonstrate continuous compliance?

Accepted Answer

Fuel usage and heat input rate

Answer

Fuel usage and heat input data allow calculation of actual NOx emissions in lb/MMBtu for comparison against the permit limit.

Question 5

EPA's Subpart DDDDD (National Emission Standards for Industrial, Commercial, and Institutional Boilers) is commonly known as the Boiler MACT. What is the primary pollutant driving compliance for large solid-fuel boilers?

Accepted Answer

Mercury

Answer

Mercury is the primary driver of Boiler MACT compliance for major source solid-fuel boilers due to its toxicity and bioaccumulation.
