Weyerhaeuser proposes to modify its existing Lime Kiln at the Valliant Mill to accommodate the combustion of petcoke in the kiln. As a result, the existing Lime Kiln will be retrofitted with the necessary petcoke combustion equipment. In addition, the necessary petcoke receiving, storage, and handling equipment will be constructed.

The impact of petroleum coke burning on SO2emissions from lime kilns can be insignificant in spite of the relatively high levels of sulfur (S) in petroleum coke, 4.9% on average. As with other kiln sulfur inputs, this outcome is also attributable to the high degree of in-situSO2capture capability of lime kilns (NCASI 2005).
