CEMEX Fairborn Plant Clean Air Act Settlement

CEMEX Fairborn Plant Clean Air Act Settlement Resources

"Emissions of harmful pollutants like sulfur dioxide and nitrogen oxides can lead to a number of serious health and environmental problems, including premature death and heart disease. Today's settlement will help keep harmful air pollution out of Ohio communities, protect children with asthma and prevent region-wide public health problems." - Cynthia Giles, Assistant Administrator of EPA’s Office of Enforcement and Compliance and Assurance.

(Washington, DC - February 10, 2011) The U.S. Environmental Protection Agency (EPA) and the U.S. Justice Department announced today that Cemex, Inc., one of the largest producers of Portland cement in the United States, has agreed to pay a $1.4 million penalty for Clean Air Act violations at its cement plant in Fairborn, Ohio. In addition to the penalty, Cemex will spend an estimated $2 million on pollution controls that will reduce harmful emissions of nitrogen oxides (NOx) and sulfur dioxide (SO2), pollutants that can lead to childhood asthma, acid rain, and smog.

Overview of Company and Location of Facilities

CEMEX is a global building materials company headquartered in Mexico.  CEMEX provides cement and concrete products for construction projects in every sector: industrial, commercial, residential and municipal, with more than 100 aggregate quarries and hundreds of ready-mix concrete plants in the United States. 

CEMEX is one of the largest producers of Portland cement, owning and operating 14 Portland cement plants in the U.S. and Puerto Rico.  The U.S. headquarters is located in Houston.

The CEMEX Fairborn facility is located in Fairborn, Ohio.  The Facility operates one pre-heater cement kiln with a capacity of 661,000 tons of cement clinker per year.  Emissions are approximately 2,963 tons of nitrogen oxide (NOx) and 673 tons of sulfur dioxide (SO2) per year.

Violations

The Complaint alleges that CEMEX constructed or made major modifications at the Fairborn plant resulting in increased emissions of NOx and SO2 without first obtaining a pre-construction permit and installing required pollution control equipment. These actions violate the Clean Air Act (CAA) Prevention of Significant Deterioration (PSD) provisions, Part C of the Title I, at §§ 7661a-f; and CAA 42 U.S.C. §§ 7470-7492.

In addition, the Complaint alleges that CEMEX violated Title V and the federal and state approved regulations by failing to submit accurate and complete permit applications, which include all applicable requirements (including the relevant PSD requirements and the requirement to apply best available control technology pursuant to PSD).

Injunctive Relief

The consent decree requires CEMEX to install and continuously operate best available control technology (BACT) level emissions controls to reduce emissions of NOx and SO2.

The consent decree requires the installation and continuous operation of a selective non-catalytic reduction (SNCR) unit to control NOx emissions.  While the plant is required to conduct testing in order to set a final NOx limit after the consent decree is entered, CEMEX is required to design the SNCR to obtain and maintain a 30-day rolling average emissions rate of no greater than 1.85 lbs of NOx per ton of clinker produced.

Currently, the Fairborn plant does not utilize an SO2 add-on control device.  The consent decree will require the installation and continuous operation of a lime spray absorber on the alkali bypass stack.  CEMEX will be required to meet a 30-day rolling average emission rate of no greater than 1.1 lb SO2/ton of clinker.
