On October 23, 2025, EPA Region 1 filed an Expedited Settlement Agreement ( ESA ) with Pioneer Plastics Corporation, thereby resolving violations of the Clean Air Act's Risk Management Program ( RMP ) regulations, promulgated pursuant to Section 112(r) of the Act, at the company's plant in Auburn, ME. Pioneer Plastics produces high pressure laminate, treated paper/fiberglass, and polyester resins. Formaldehyde, a chemical subject to the RMP regulations, is used in the production of resins. EPA identified violations of the RMP regulations that included: pipe labeling issues, unlabeled formaldehyde alarms, damaged formaldehyde pipe insulation, unlabeled formaldehyde piping, formaldehyde transfer hoses not properly cared for, and a lack of NFPA signs identifying hazardous chemicals. The ESA requires compliance and payment of total penalties of $10,200. Maine is not delegated to implement this program.
