Permit Details



In May 2019, we submitted a permit amendment to the Texas Commission on Environmental Quality (TCEQ) seeking restoration of pre-2017 carbon monoxide limits that have been in effect for 20 years, and removing a voluntary limit of 30% from our 2007 application, thereby allowing us to use the most economical and efficient mix of fuel sources. Petcoke is a common fuel that can be utilized by all cement kilns in Midlothian. The Holcim plant has successfully used petcoke since 2006. We are simply requesting the same flexibility as other cement kilns in Midlothian.
