Following board approval of a $125 million capital outlay, Overland Park, Kan.-based Ash Grove Cement will incorporate a new preheater, precalciner production system at its Midlothian mill outside the Dallas-Ft. Worth metroplex. The equipment will position the facility among Texas’ lowest emitting cement producers and become the biggest ticket investment to date tied to the Environmental Protection Agency’s portland cement National Emissions Standards for Hazardous Air Pollutants (NESHAP) rule, effective September 2015.
