It also requires the company to install a pollution control device known as a Selective Non-Catalytic Reduction System (SNCR) on one of the plant’s coal-fired units, upgrade its sulfuric acid mitigation system, and continually operate all of its pollution control equipment to meet levels that will achieve reductions in NOx, SO2, PM and H2SO4 emissions.
Additionally, the agreement recognizes that IPL may permanently retire two of its units at the Petersburg Generating Station earlier than planned. Therefore, the company may forego installing the control device if it decides to retire the two units before July 1, 2023. Discontinuing the operations of those units will result in significant emissions reduction—greater than any reductions achieved by installing and operating the SNCR.
Furthermore, the agreement requires IPL to pay a total civil penalty of $1.525 million, of which $925,000 will go to the U.S. government and $600,000 to the State of Indiana.
Moreover, the agreement requires IPL to undertake a project costing $5 million to mitigate the harm to the environment caused by the plant’s excess emissions over the years.
