1/4" x 0 .........................................................................……..15% Maximum

TOTAL .……………………………………………………....100%

C.7. AS RECEIVED SULFUR:

The sulfur content (as received analysis basis) of the coal shall be restricted to assure compliance with the State of Wisconsin Department of Natural Resources air pollution requirements for sulfur dioxide emissions. Further, the calculated sulfur dioxide emission rate shall not exceed 1.43 lbs. SO2 per million BTU. The method of determining the sulfur dioxide emission rate is:

E = 38 x (S) / H.V.

Where: 38S = lbs SO2 / ton coal, S = Sulfur content (as received analysis basis) written as percent, i.e., 1.00% = 1 numeric entry.

H.V. = Heating Value (as received analysis basis) expressed in units of million BTU per ton, i.e. 13,300 BTU/lb. = 26.6 x 106 BTU/ton = 26.6 numeric entry.

E = Resultant emission rate of sulfur dioxide expressed in units of pounds of SO2 per million BTU heating value of the coal.

Example Calculation:

Bid Guarantee Analysis (as received basis): Sulfur = 1.0 %; BTU/lb. = 13,300.

E = 38 x (1) / 26.6 = 1.43 lbs. SO2 per million BTU.
