This refinery is evaluating increasing tar sands processing at the refinery. In 2004, it purchased 7% blended bitumen from the tar sands.
The "Crude / Coker Utilization Project" (CCUP) will increase throughput (although not capacity), resulting in "significant" increases of NOx, CO, PM, and PM10 (serving as a surrogate for PM2.5), for purposes of PSD review. However, IEPA found that no the project units contributing to the increases did not undergo a "physical or operational change," and so were not subject BACT or LAER. Although the purpose of the expansion remains unclear, the geographic location suggests that this is a tar sands expansion.
