EEE 304 CERTIFICATION SCRIPT 2026
QUESTIONS WITH SOLUTIONS GRADED A+
◍ How many metric tons of CO2e emissions result from flaring annually?.
Answer: Over 350 million metric tons
◍ How do carbon taxes differ from emissions trading systems (ETS)?.
Answer: Carbon taxes set a price per ton of GHG emissions, while ETS sets
a cap on total emissions with tradable allowances.
◍ What are the types of underground natural gas storage facilities and how do
they work?.
Answer: Depleted reservoirs (86%, majority of both working gas capacity
and daily deliverability), aquifers (10%), and salt caverns (4%, minimal
working gas capacity, high level of deliverability).They are reconditioned
before being injected with natural gas, becoming pressurized gas containers.
The higher the pressure the more readily the gas can be extracted, but some
gas must remain in the chamber at all time
◍ What is the role of the EPA's TRI program?.
Answer: The TRI program reports on toxic releases and identifies critical
minerals in mining waste and acid mine drainage.
◍ What is the primary cause of acid rain?.
Answer: Sulfuric acid formed from sulfur dioxide emissions.
◍ What was the significance of the 2009 endangerment finding?.
Answer: It established that GHGs are a threat to human health, giving the
EPA authority to regulate them.
◍ What are the issues with hydrofracking?.
Answer: It consumes 1.5 to 9.7 million gallons of water per well, depleting
natural resources and contaminating drinking water with fracking fluid and
, chemical run off
◍ What are some examples of critical minerals?.
Answer: Examples include lithium, boron, silicon, aluminum, titanium,
cobalt, copper, and silver.
◍ What are the health concerns associated with abandoned uranium mines?.
Answer: Abandoned uranium mines contribute to long-term health concerns
from radiation and metal exposure in nearby communities.
◍ What is the Global Warming Potential (GWP) of methane compared to
CO2?.
Answer: Methane has a GWP of 80 times that of CO2.
◍ What is a major environmental concern associated with coal ash landfills?.
Answer: Because they are unlined, they can contaminate groundwater,
surface water, and soil with toxins above safe drinking standards.
◍ What is rejected energy?.
Answer: Rejected energy is the energy that doesn't go towards a useful
service and is not consumed.
◍ What is the significance of the term 'MACT' in air pollution regulation?.
Answer: It refers to technology-based standards for hazardous air pollutants.
◍ Generation of SO2 by redox reaction of sulfur in coal during combustion.
Answer: Fossil fuel combustion leads to the oxidation of sulfur. Sulfur is
oxidized and oxygen is reduced. This happens at high temperatures. Iron
disulfide (pyrite, fool's gold) reacts with oxygen to produce solid hematite
(iron (III) oxide) and SO2 gas which is absorbed by the atmosphere for acid
rain.The result of coal combustion by power plants
◍ EPA and hazardous air pollutants (HAPs)?.
Answer: 188 cancer-causing air toxins found in various emissions that the
EPA regulates. Often found in gas, dry cleaner emissions, paint stripper,
asbestos, etc. EPA regulates them from both major industries and small
sources through standards
