ASH GROVE UPGRADE AMPLIFIES EPA MERCURY RULE'S HIGH COST

摘要

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 emit-ting 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 (NE-SHAP) rule, effective September 2015.
