Owner Objective

Lafarge North America, the largest diversified supplier of construction materials in the U.S. and Canada, produces and sells cement, ready-mixed concrete, aggregates, asphalt, paving and construction, precast solutions and pipe products. Lafarge required expansion of their Three Rivers Aglime process.

CEC Approach

CEC prepared a permit application and emission calculations for the construction of new equipment associated with the expansion. The permit application allowed the facility to construct the new equipment and modified the facility’s State Origin Permit for minor sources. In addition, CEC prepared a permit application for the temporary addition of a portable screen and radial stacker for the facility’s Rip Rap plant.
