USCA Case #24-1287 Document #2077531 Filed: 09/30/2024 Page 3 of 81 since 2011). 6. For these reasons, I have personal knowledge of the facts and information in this declaration. SunCoke's Unique Heat Recovery Process Provides Environmental Advantages. 7. Coke is an essential ingredient in the blast furnace production of steel. Maintaining a strong domestic steel industry is critical to national defense, the health of the nation's infrastructure, and many manufacturing industries. 8. Metallurgical coke is produced by the destructive distillation of coal in coke ovens. There are only 11 active coke facilities in the United States-6 of these are byproduct recovery (ByP) facilities and 5 are heat and/or nonrecovery (HNR) facilities. Heat recovery facilities use the waste heat from coke oven gas to produce steam in on-site heat recovery steam generators (HRSG) which is then used to make electricity (which is considered green electricity and green process steam since it is recovered from waste heat). SunCoke owns all five of the HNR and all but one of the facilities (JWO) use HRSGs, producing both coke for the steel industry and process steam/electricity.
