Various competing 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 own and 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.


QA/QC Policy and Approach 1.  It starts with a selecHve 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 opHmize our processing condiHons 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 applicaHon.

4.  We control every aspect of physical material control including transportaHon assets to ensure against contaminaHon.

4 Key Steps to Ensuring Reliability and Consistency


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 selecHve about the coal

that we produce and deliver to the plant –  20+ year supply of coal reserves under

lease –  Close proximity to our plant

•  Partnership with North American Coal to operate

•  Full integraHon within our operaHons team

We Take the “Filet” of the Coal Seam


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 automaHon –  Over 15 sampling locaHons checking in-‐process quality

•  Our focus on Mercury Control means that we ONLY make one furnace product

–  Allows us to opHmize performance for one applicaHon –  Set process operaHons and automaHon 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: SpecificaHons and Measurements that Mafer

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.

We Measure What Mafers in Mercury Control

Surface area is not a reliable predictor of in flight mercury capture The same can be said for other tradi8onal measures of quality like ash, moisture, methylene blue etc.

Our approach is to combine meaningful applica=ons tes=ng with other applica=ons and analy=cal tes=ng. ADA Carbon SoluHons Dynamic Mercury Index (DMI) •  Over 3 years ADA Carbon SoluHons developed a

bench scale test that mimics in flight mercury capture

•  Demonstrated repeatability and reproducibility •  Demonstrated strong correlaHon to in field results


•  Dedicated trailers and railcars

•  Trained drivers

•  Operate 4 commercial transload staHons today; more in the future as usage increases

•  Efficient, safe and clean delivery

•  Close coordinaHon with your plant and ACI equipment vendors to ensure effecHve PAC delivery into the duct

•  Run contemporary S&OP process internally

•  Focused on Power industry and sensiHve to reliability requirements

Reliability Delivered to Your Door

Step 4: Control Over TransportaHon Assets


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 intenHons. It is what happens when what you do matches your customers’ expectaHons.” !  Control over raw materials

!  Control over processing condi8ons

!  Deployment of meaningful QC tes8ng that correlates to mercury capture performance

!  Control over delivery assets to limit opportuni8es for contamina8on 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 presentaHon 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.
