Cypress Semiconductor Corp. allegedly violated the Emergency Planning and Community Right-to-Know Act by failing to submit complete and correct forms to the EPA and the state regarding how much hydrogen fluoride it used in 2004 and 2005, according to the EPA.
"If you're a facility that uses toxic chemicals, you must provide complete and accurate information about these chemicals so residents and emergency responders are aware of possible chemical hazards in the community," EPA Pacific Southwest Communities and Ecosystems Director Enrique Manzanilla said. "Cypress Semiconductor voluntarily disclosed the violations and corrected them, ensuring compliance with federal law."
At its 3901 N. First St. facility, the company used about 17,125 pounds of hydrogen fluoride in 2004 and about 18,464 pounds in 2005. According to the EPA, both amounts exceed the 10,000-pound threshold for reporting.
