CONSENT DECREE
Under this Decree, Essroc will install and continuously operate a selective non-catalytic reduction system (SNCR) for controlling NOx at five kilns, including 2 at the Speed facility, and meet emission rates that are akin to Best Available Control Technology at each kiln. For controlling NOx, Essroc will also demonstrate a selective catalytic reduction system (SCR) at the Logansport facility. If the SCRs are successful, these will be the first SCRs on these types of kilns (wet process kilns) anywhere in the world. If they are not successful, the proposed Decree requires that Essroc install SNCR at each of the Logansport kilns. For controlling SO2, Essroc will install a Dry Scrubber/Lime Injection system at seven kilns, including four at the Indiana facilities, and meet BACT- like emission rates at each kiln. The remaining two kilns in the proposed settlement will be permanently retired.
EMISSION REDUCTIONS AND INJUNCTIVE RELIEF EXPENDITURE
Upon full implementation, the plants? SO2 and NOx emissions will be reduced by over 8,000 tons per year (TPY). With respect to NOx emissions, contributions from the Speed and Logansport plant will be reduced by at least 1,204 TPY. SO2 will be reduced from these plants by at least 2,438 TPY. These reductions secure significant human health and environmental benefits.
Essroc will install SCR and scrubber systems at Kilns 1 and 2 of the Logansport facility, no later than 2015, at a cost of thirteen million dollars. Essr
