Oak Grove Not applicable - does not burn oil

Note on Testing: All 2009 oil testing results for trace metals (mercury and vanadium) were non-detect. Chlorine and fluorine were not tested. Test results are available upon request.

Please note that < 0.01% of Btu's per plant come from burning oil, except for Sandow Station which began operation in 2009.

Note on Shipments: Sandow No 4 and Sandow Station share a common fuel oil tank. Oil shipments are prorated by amounts burned per plant.

Notes:

For each plant, coal shipments (dry tonnage) are estimated based on wet tonnage (as received) and average annual moisture % for the plant.

For Martin Lake, Monticello, and Oak Grove: coal shipments where a single mine covers multiple counties, the single predominant county is reported for the entire mine's tonnage.

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.
