US: Continental Cement Company will pay a US$74,440 civil penalty and spend at least US$282,000 to procure low-emission buses for a local school district as part of a settlement following alleged Clean Air Act violations. The replacement propane buses will reduce air pollution in areas impacted by excess emissions from Continental Cement’s operations.

According to the Environmental Protection Agency (EPA), it identified inadequate operation of leak detection systems during a December 2022 inspection, which are designed to notify the company of potential hazardous emissions. Without a functioning leak detection system, the facility would be unaware of whether pollutant filters are operating effectively to reduce emissions of particulate matter and other air pollutants.

US: Lafarge North America has agreed with the US Environmental Protection Agency (EPA), the US Department of Justice and New York State to provide US$1.5m towards projects to reduce air pollution in the community surrounding its Ravena cement plant. The agreement also grants Lafarge additional time, until 1 July 2016, to reduce air pollution from the cement plant.

"This agreement will reduce the pollution limits required by the settlement at this facility by providing a significant amount of funding for projects that will improve local air quality," said EPA Regional Administrator Judith A Enck.

A March 2010 settlement between the federal government and Lafarge North America over violations of the Clean Air Act required that the cement producer either install controls on two kilns at its Ravena plant or replace those kilns with a lower emitting kiln by 1 January 2015. In return for the deadline extension, Lafarge has committed to interim air pollution limits at the existing kilns intended to result in the same or higher reductions as would have been required by the original agreement in addition to funding local air pollution reduction measures.

US: The Environmental Protection Agency (EPA) has fined Ash Grove Cement US$2.5m and is forcing the American cement producer to invest US$30m in pollution controls at its plants in nine US states that are alleged to have violated the Clean Air Act.

The EPA and the US Department of Justice announced the penalty jointly on 19 June 2013. The EPA said that the action would reduce thousands of tonnes of harmful pollutants at plants in Arkansas, Idaho, Kansas, Montana, Nebraska, Oregon, Utah, Washington and Texas. In addition Ash Grove Cement will spend US$750,000 towards mitigating the effects of past excess emissions.

Ash Grove acknowledged the agreement in a statement and said that it is striving to comply with environmental regulations at all its facilities. It disputes that it violated the Clean Air Act, saying it opted to enter this agreement with federal regulators rather than face rising costs in time and financial resources that would have accompanied further discussions with the EPA.

"The agreement with the EPA will allow Ash Grove to move forward and provide an environmentally sustainable product that is the foundation of our economy," said Charles T Sunderland, the company's chairman and chief executive officer.

The EPA said that its agreement with Ash Grove Cement, lodged on 19 June 2013 in the US District Court for the District of Kansas, is the first settlement with a cement producer that also requires injunctive relief and emission limits for particulate matter, a combination of combustion gasses and fine dust. There is a 30-day public comment period before final court approval.

The US$2.5m penalty will be distributed to eight states and one agency that took part in the agreement: Arkansas, Idaho, Kansas, Montana, Nebraska, Oregon, Utah, Washington and the Puget Sound Clean Air Agency. Ash Grove will also spend US$750,000 on a project to replace old diesel truck engines at its facilities in Kansas, Arkansas, and Texas, estimated to reduce smog-forming nitrogen oxides by approximately 27t/yr.
