Mercury control technology PAC producers vary in terms of their control over the key elements
of their supply chain. In some cases, suppliers rely 100% on toll manufacturing and licensed
technology. In others, PAC is imported from overseas and finished or treated domestically. In
the case of ADA-CS, we control everything from the selective mining of coal through
processing all the way to the transportation assets used to deliver carbon. We control it all and
therefore can ensure quality, consistency and reliability.

2. 2Expertise. Reliability. Compliance.
QA/QC Policy and Approach
1. It starts with a selective and precise approach to mining coal
as a feedstock as opposed to a fuel.
2. Our laser focus on flue gas mercury control means that we
can optimize our processing conditions with one purpose in
mind…..and then automate it to ensure consistency.
3. We have developed meaningful QC tests that correlate
directly to dynamic in-flight capture in a flue gas application.
4. We control every aspect of physical material control
including transportation assets to ensure against product
contamination.
4 Key Steps to Ensuring Reliability and Consistency

3. 3Expertise. Reliability. Compliance.
Step 1: Consistent Raw Materials
• We made a strategic investment in
Five Forks Mine
– 100% of the coal is mined with our
specific purpose in mind
– This mine operates in a very different
way than a typical coal mine
– We are very selective about the coal
that we produce and deliver to the plant
– 20+ year supply of coal reserves under
lease
– Close proximity to our plant
• Operated by a subsidiary of the
North American Coal Corporation
• Full integration within our
operations team
Quality Control Processes Produce Coal as a Critical Raw Material for PAC as
Opposed to a Fuel

Step 2: Constant Process =
Constant Quality
• Red River represents the most automated, most
efficient and environmentally friendly PAC plant
in North America.
– 6000 points of automation
– Over 15 sampling locations checking in-process quality
• Our focus on Mercury Control means that we
ONLY make one furnace product
– Allows us to optimize performance for one application
– Set process operations and automation capability
ensure consistency
• We invest in our people
– Our investment in training is 12% of our labor cost
– Highly trained, highly engaged workforce
– Quality is a culture that permeates everything we do
“Quality is not an act. It is a habit.”.... Aristotle

Step 3: Specifications and Measurements
that Matter
We Measure What Matters in Mercury Control
Have you ever wondered…..”what does
iodine number or surface area mean in
terms of performance in mercury
capture??”
Don’t worry…..so have we. So we studied it.
Surface area is not a reliable predictor of in flight
mercury capture
The same can be said for other traditional measures of
quality like ash, moisture, methylene blue etc.
Our approach is to combine meaningful
applications testing with analytical
testing.
ADA Carbon Solutions Dynamic Mercury Index (DMI)
• Over 3 years ADA Carbon Solutions developed a
bench scale test that mimics in flight mercury
capture
• Demonstrated repeatability and reproducibility
• Demonstrated strong correlation to in field results

6. 6Expertise. Reliability. Compliance.
• Dedicated trailers and railcars
• Trained drivers
• Operate 4 commercial transload
stations today; more in the future as
usage increases
• Efficient, safe and clean delivery
• Close coordination with your plant
and ACI equipment vendors to ensure
effective PAC delivery into the duct
• Run contemporary S&OP process
internally
• Focused on Power industry and
sensitive to reliability requirements

Summary
• We are 100% focused on power plant mercury control.
• As a result everything we do is done with the concerns of the power
industry in mind.
• “Quality is not what happens when what you do matches your intentions. It
is what happens when what you do matches your customers’ expectations.”
 Control over raw materials
 Control over processing conditions
 Deployment of meaningful QC testing that correlates to mercury capture performance
 Control over delivery assets to limit opportunities for contamination
If Quality and Consistency are important and concerning to you, let us explain in further
detail our approach to quality assurance. As a supplier that is 100% focused on the
energy industry, we are keenly aware of the importance of reliable performance. This
presentation offers a highlight of our approach but there is much more detail behind the
story. We would be very happy to visit and explain our full and unwavering commitment
to quality.
