U.S. EPA reached a settlement with Hercules Inc. on alleged clean-air violations at the company's chemical plant at 5228 N. Hopkins St., Milwaukee, Wis. The agreement, which includes a $22,500 penalty, resolves EPA’s charges that Hercules failed to control leaks of hazardous air pollutants from its equipment.
EPA said Hercules had an uncapped open-ended line, had delayed repair of another line, and had not tagged relevant equipment. According to EPA, the company has now complied with these requirements and improved its leak-management system.
