On June 30, 2015, Region 1 entered into an Expedited Settlement Agreement (ESA) with Tiverton Power LLC of Tiverton, Rhode Island for alleged violations of Section 112(r)(7) of the Clean Air Act. The ESA penalty was calculated under a national expedited settlement program, which is intended to apply to relatively minor, easily correctable RMP violations. Tiverton Power LLC operates a combustion turbine combined cycle power plant which uses anhydrous ammonia, an extremely hazardous substance, as a refrigerant in the air inlet chiller to enhance gas turbine performance and efficiency. The facility has corrected the violations and will pay a penalty of $11,040.
