Region 1 issued two Administrative Penalty Orders (APOs) to Hubbard-Hall, Inc. for chemical warehouses in Wilmington, Massachusetts and Waterbury, Connecticut that store and process chemicals. At both facilities, the company violated Section 112(r) of the CAA by failing to develop and submit risk management plans for hydrofluoric acid. The APOs seek up to the statutory maximum penalty for 12 months of documented violations at Waterbury and 14 months of documented violations at Wilmington.
