Which federal rule requires facilities emitting 25,000 metric tons or more of CO2 equivalent per year to report their greenhouse gas emissions to the EPA?
Answer: Greenhouse Gas Reporting Program (GHGRP)
The EPA's Greenhouse Gas Reporting Program (GHGRP) mandates annual GHG reporting from large emitters of 25,000 metric tons CO2e or more.
Which of the following gases is NOT classified as a greenhouse gas regulated under the Clean Air Act?
Answer: Nitrogen (N2)
Nitrogen (N2) makes up ~78% of the atmosphere and is not a greenhouse gas; it does not trap heat radiation.
What is the primary purpose of a State Implementation Plan (SIP) in the context of greenhouse gas and climate regulations?
Answer: To outline how a state will achieve and maintain National Ambient Air Quality Standards
A SIP details how each state plans to attain and maintain NAAQS, serving as the state's regulatory roadmap submitted to the EPA.
The global warming potential (GWP) of a greenhouse gas is measured relative to which reference gas?
Answer: Carbon Dioxide (CO2)
GWP is always measured relative to CO2, which is assigned a GWP of 1 over a 100-year time horizon.
Which DEQ program addresses stationary source emissions of greenhouse gases through permit requirements under the Clean Air Act?
Answer: Title V Operating Permits
Title V Operating Permits under the Clean Air Act are the primary permitting mechanism that can include GHG emission conditions for large stationary sources.
What does 'CO2 equivalent' (CO2e) mean when reporting greenhouse gas emissions?
Answer: A standardized unit comparing the climate impact of different GHGs relative to CO2
CO2e converts emissions of various GHGs into a single comparable unit by multiplying each gas's mass by its global warming potential relative to CO2.
Under the Clean Air Act, which type of permit is required when a new major source or major modification of an existing source could significantly increase GHG emissions in an attainment area?
Answer: Prevention of Significant Deterioration (PSD) Permit
PSD permits are required for new major sources or major modifications in attainment areas and include a Best Available Control Technology (BACT) review for GHGs.
