FACILITY DESCRIPTION
RMC Lonestar operates a portland cement manufacturing facility in Davenport, California. This facility has been in operation since 1906. The facility utilizes a Preheater/Precalciner Type Cement Kiln. Limestone and shale are quarried at the facility location. These quarried materials along with other purchased raw materials are ground, dried and supplied in the appropriate chemical proportions to the preheater/precalciner tower and then to the rotary kiln to produce clinker. The clinker is cooled, then finish ground with additives in accordance with the final product's desired properties. The finished product is sacked or stored in silos prior to bulk shipment by truck or railcar. The RMC Lonestar Davenport Plant is considered a federal Major Source and subject to the Title V permitting program due to the potential to emit Oxides of Nitrogen (NOx), Oxides of Sulfur (SOx), Carbon Monoxide (CO), and Particulate Matter less than 10 microns in diameter (PM10).

GENERAL CONDITIONS 49. RMC Lonestar shall comply with all conditions of this federal operating permit. Any noncompliance with a permit condition constitutes a violation of the Federal Clean Air Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or for denial of a permit renewal application. [District Rule 218] 50. In an enforcement action, the fact that RMC Lonestar would have to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit is not a defense.
