R 336.1402 Emission of SO2 from fuel-burning equipment at a stationary source other than power plants.

Rule 402. (1) For fuel burning equipment at a stationary source other than a power plant it is unlawful for a person to cause or allow the emission of SO2 from the combustion of any coal or oil fuel in excess of 1.7 pounds per million Btu of heat input for oil fuel or in excess of 2.4 pounds per million Btu of heat input for coal fuel. (2) The provisions of subrule (1) of this rule do not apply to fuel-burning equipment at a stationary source that is unable to comply with the specified emission limits because of SO2 emissions caused by the presence of sulfur in other raw materials charged to the fuel- burning equipment. This exception applies if at any time the actual SO2 emission rate exceeds the expected theoretical SO2 emission rate from fuel burning. The expected theoretical SO2 emission rate must be based on the quantity of fuel burned and the average sulfur content of the fuel. (3) For fuel burning equipment at a stationary source located in Wayne county other than a power plant, it is unlawful for a person to burn fuel that does not comply with the sulfur content limitation of table 43 and unlawful to cause or allow a discharge into the atmosphere from fuel burning equipment SO2 in excess of the SO2 concentration limit shown in table 43. (4) Table 43 reads as follows: Table 43 Fuel and SO2 Concentration Limitations for Fuel Burning Equipment(c) at a Stationary Source Located in Wayne County Other than a Power Plant Fuel Type Maximum Weight Percent Sulfur Content in Fuel(a, b) Limitations for Fuel- Burning Equipment SO2 ppmv Emission Rates Corrected to 50% ExcessAirb Coal 0.75 420 Distillate Oil Nos. 1 & 2 0.30 120 Used Oil 1.0 300 Crude and Heavy Oil Nos. 4, 5, & 6 1.00 400 (a) The determination of sulfur content (percent by weight) of fuel shall be carried out in accordance with the “Standard Test Methods for Sulfur in Petroleum Products:” ASTM D129, D1266, or D1552 and the “Standard Test Methods for Total Sulfur in the Analysis of Coal and Coke:” ASTM D3177 or D4239; as referenced in 40 C.F.R. 60.17, adopted by reference in R 336.1902. (b) Records must be kept, including the identification of the fuel burning equipment, days of operation, and maximum sulfur content of fuel combusted for each day of operation. Records must be maintained on site for 5 years and submitted to the department upon written request. (c) For table 43, fuel burning equipment includes residential and commercial space and water heating. The maximum weight percent sulfur content in fuel and SO2 ppmv emission rate limitations for distillate, crude, and heavy oils listed above also apply to these units. (5) The following provisions apply to persons in Wayne county: (a) The maximum weight percent sulfur content in fuel limitations for fuel-burning equipment provisions of table 43 of this rule do not apply to a person who uses a combination of fuels in such ratios as to meet the SO2 concentration limitations specified in table 43 and has obtained written approval from the department for this exemption. The allowable concentration limit will be based on the value in the table for the fuel having the higher allowable concentration limit. (b) The maximum weight percent sulfur content in fuel limitations for fuel-burning equipment provisions of table 43 of this rule do not apply to a person who has received an installation permit from the department for a control device to desulfurize the stack gases if the control device is installed and operating properly.
