CAP Emissions Reduction Strategies 2

Question 1

Under the EPA's Greenhouse Gas Reporting Program, which industrial sector is required to report emissions using the Tier 3 method for combustion sources?

Accepted Answer

Large facilities where CO2 concentration is continuously monitored using CEMS

Answer

Tier 3 requires continuous emissions monitoring systems (CEMS) to directly measure CO2 concentration and flow rate, applying to large combustion facilities under EPA's GHGRP.

Question 2

A company switches its vehicle fleet from gasoline to compressed natural gas (CNG). Which Scope of emissions is primarily affected?

Accepted Answer

Scope 1 only

Answer

Fleet vehicles burning CNG on-site generate direct (Scope 1) combustion emissions, replacing gasoline-based Scope 1 emissions.

Question 3

Which abatement measure is most effective for reducing methane emissions from coal mine ventilation air (VAM)?

Accepted Answer

Thermal flow reversal reactors (TFRR)

Answer

TFRRs oxidize very low-concentration methane in ventilation air by reversing flow direction to maintain combustion temperatures, making them the primary VAM mitigation technology.

Question 4

In life cycle assessment (LCA), which system boundary approach allocates upstream emissions from raw material extraction to the product being studied?

Accepted Answer

Cradle-to-gate

Answer

Cradle-to-gate includes all emissions from raw material extraction through manufacturing but excludes use-phase and end-of-life stages.

Question 5

A steel manufacturer installs electric arc furnaces (EAF) powered by renewable energy instead of basic oxygen furnaces (BOF). Which primary emission benefit results?

Accepted Answer

Significant reduction of Scope 1 process CO2 from iron ore reduction

Answer

BOF uses coke to reduce iron ore, creating large Scope 1 CO2 process emissions, while EAF melts recycled scrap steel electrically, largely eliminating those direct process emissions.
