1/9/2023 Rachel reported the facility did not end up using coal yet, but will likely be doing so tomorrow. The usage is dependent on natural gas prices. See email below: Glaza, Rachel M (Mason City) USA 10:11 AM (3 hours ago) to Mark, me, Joe, Sean, Wendy Good Morning all, We did plan to have the coal mill system running by January 1st of 2023 however that has not happened. We hope to start it up sometime this week and I will keep you all informed. We do still plan to have stack testing the week of January 23rd, 2023. If the coal mill is not running we will go forward with stack testing for the kiln stack and cooler. If the coal mill is running we will plan on testing it. If you have any questions, please let me know. Thank you, Rachel Glaza Environmental Manager Heidelberg Materials US Cement LLC DAVID KNOLL
