Today, Kingspan employees working at the company’s Santa Ana, Calif., manufacturing plant and the International Association of Sheet Metal, Air, Rail and Transportation Workers (SMART), jointly filed a whistleblower complaint against Kingspan Light + Air (“Kingspan”), alleging that the company has been violating the Clean Water Act by not adhering to best management practices.

The complaint calls upon the State Water Resources Control Board, Office of Enforcement (a division of CalEPA), and the Santa Ana Regional Water Quality Control Board to investigate Kingspan’s compliance with its Storm Water Pollution Prevention Plan (SWPPP) at its Santa Ana manufacturing facility. The complaint includes allegations that Kingspan instructed workers to use a leaf blower to blow dust and debris, rather than vacuuming it up per the terms of its SWPPP.

SMART is a union that represents sheet metal workers, welders, production employees and more in industries across the United States and Canada. Based on interviews with Kingspan workers, a SMART investigation has revealed that Kingspan has not adhered in enumerated ways to the Best Management Practices (“BMPs”) set out in the SWPPP and associated documents.
