Michigan Administrative Code › Department - Environmental Quality › Air Quality Division › Part 4 - EMISSION LIMITATIONS AND PROHIBITIONS-SULFUR BEARING COMPOUNDS › Section R. 336.1401 - Emission of sulfur dioxide from power plants

Current through Vol. 24-12, July 15, 2024
Rule 401.
(1) In a
				power plant, it is unlawful for a person to burn fuel that does not comply with
				the sulfur content limitation of table 41 or which, when burned, results in
				sulfur dioxide (SO2) emissions exceeding an equivalent
				emission rate as shown in table 41. In a power plant located in Wayne county,
				it is unlawful for a person to bum fuel that does not comply with the sulfur
				content limitation of table 42 and unlawful to cause or permit a discharge into
				the atmosphere from fuel-burning equipment SO2 in excess
				of the SO2 concentration limit shown in table
				42.
(2) Tables 41 and 42 read as
				follows:

(a) The total steam production capacity of all
								coal- and oil-burning equipment in a power plant as of August 17, 1971.
(b) "Maximum average sulfur content in fuel" means
								the average sulfur content in all fuels burned at any 1 time in a power plant.
								The sulfur content shall be calculated on the basis of 12,000 Btu per pound for
								solid fuels and 18,000 Btu per pound for liquid fuels.
(c) Solid fuels include both pulverized coal and
								all other coal.
(d) Liquid fuels include distillate oil (No. 1 and
								No. 2), heavy oil (No. 4, No. 5, and No. 6), and crude oil.
(e) A person shall sample, analyze, calculate, and
								record for each day of operation for each unit at the power plant, the sulfur
								content of the fuel combusted or the fuels equivalent
								SO2 emission rate in accordance with as-fired fuel
								sampling and analysis procedures found in appendix A of 40 CFR part 60; in
								particular 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 CFR
								60.17, adopted by reference in
								R
								336.1902. Records must be kept, including the
								identification of the power plant, 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.

								content of the fuel combusted and the fuels equivalent
								SO2 emission rate in accordance with as-fired fuel

								request.
(3)
				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 42 of this
				rule do not apply to any person who uses a combination of fuels in such ratios
				as to meet the SO2 concentration limitations specified
				in table 42 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 42 of this
				rule do not apply to any 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.
