1 An asterisk (*) by State name indicates a regulation that was originally stated in emissions of
pounds S02/10 Btu and has been converted to percent sulfur in the fuel.

17 For residual fuel oil only, distillate regulated to 0.2 percent.

18 If ambient air in a particular major metropolitan area other than Chicago, Peoria, and St. Louis exceeds Federal ambient air quality standards, a sulfur limitations of 1.2 percent would apply.

19 For residential and small commercial users.

20 For utilities, industrial and large commercial users.

21 Required if ambient air standards are not met.

22 For sources greater than 250X100 Btu/hr, an 0.7-percent sulfur limit applies to all fuels.
