Puerto Rico: The US Environmental Protection Agency (EPA) has announced that Cemex de Puerto Rico will spend US$1.7m on pollution controls that will reduce emissions of nitrogen oxides. In addition, the company will pay a US$160,000 penalty for Clean Air Act violations.
"Nitrogen oxides emissions can lead to a number of serious health and environmental problems, including respiratory problems, heart disease and smog," said Judith A Enck, EPA regional administrator. "The EPA settlement protects children with asthma and other vulnerable populations from harmful air pollution by requiring that Cemex install state-of-the-art technology and take immediate steps to reduce pollutants."
The Cemex cement kiln system in Ponce has operated for over 20 years and is a major source of nitrogen oxide emissions. The settlement addresses modifications Cemex made to its cement plant without obtaining the proper permit, as required by the Clean Air Act. Businesses that produce large quantities of air pollution are required to obtain permits and install pollution control technology before making changes that would significantly increase emissions.
Following an EPA inspection, Cemex conducted a smokestack test at its Ponce facility and potential violations were discovered. In the settlement, Cemex will install control technology, which will reduce emissions of nitrogen oxides by approximately 1423t/yr.
