Subject: 2013 enforcement case

 
Hi. I ran across this case recently. The article says Suncoke will "spend $100 million to install equipment known as heat-recovery steam generators to ensure that hot coking gases are routed to pollution control equipment and not vented directly into the atmosphere." Was that $100 mil each facility or $50 mil each for total of $100 mil? The $100 mil estimate was the expected total for both locations at the time of the article when the Consent Decree was entered. Did actual costs end up as expected from these quotes? Actual costs ultimately were $151.5 mil total for both locations. Are these HRSGs "extra" and dedicated for only bypass events? The new HRSGs operate continuously, not just during bypass events, to allow for gas sharing across all the ovens from each site (or each Phase at Haverhill) during normal operations. Please note that there was no increase in coal throughput as a result of the new HRSGs.  Do the two facilities still use their permitted bypass hours? Permitted venting hours are still needed for situations where gas sharing isn't possible, such as when multiple HRSGs are offline simultaneously.

Maximum Hours per Year Bypass/Waste Stacks Can Be Used Based on Permit
SC-FranklinFurnace-OH   192
SC-GraniteCity-IL  312

Lots of questions, but would appreciate any insight you can provide.
