On March 1, 2021, EPA and ITW Polymers Sealants North America Inc. (ITW) settled a Clean Air Act (CAA) administrative penalty case for alleged violations of CAA Section 112(r) and its implementing regulations at ITW's adhesive and sealant manufacturing facility in Rockland, Massachusetts. ITW violated CAA Section 112(r)(1)'s General Duty Clause (GDC) and the Risk Management Plan (RMP) regulations that implement CAA Section 112(r)(7). Many of the GDC and RMP violations involved inadequate testing and maintenance of outdoor chemical storage tanks and piping. Under the settlement, ITW will pay a penalty of $345,000 and will complete certain repair and maintenance work. ITW will also hire an independent auditor to conduct a CAA Section 112(r) compliance audit.
