Notes: Associated coal HAP testing data are shown on the following sheets. Except for Oak Grove, coal testing data are based on amounts burned per unit (not shipments per plant). For only Oak Grove Unit 1, Hg testing is tied to coal shipments as summarized in Table 2-4. For each plant, coal amounts burned (dry tons) are estimated based on wet tonnage (as received) and average annual moisture % for the plant. PRB refers to Powder River Basin sub-bituminous coal. 1 - Sandow Station November coal usage is for the partial month beginning Nov. 5.
