1. (a) Owners and/or operators of any stationary combustion installation that fires coal and has a total heat input greater than 250 million Btu per hour, where an application for a permit was received by the department after March 15, 1973, and the stationary combustion installation is not located in New York City or Nassau, Rockland or Westchester Counties, are limited to the firing of coal with 0.60 pound of sulfur per million Btu gross heat content or less. If two or more emission sources are connected to a common air cleaning device and/or emission point, the total heat input for such emission point is the sum of the total heat input of all emission sources that are operated simultaneously and connected to the common air cleaning device and/or emission point; or

2. (b) Owners and/or operators of any stationary combustion installation that fires solid fuels are limited to the firing of solid fuel with a sulfur content listed in the table below. On and after July 1, 2023, all emission sources, including process and incineration sources that fire solid fuels, are limited to the firing of solid fuel with a sulfur content listed in the table below:

   Area	Solid fuel (pounds of sulfur per million Btu gross heat content)
   New York City, Nassau, Rockland and Westchester Counties	0.2 MAX
   Suffolk County: Towns of Babylon, Brookhaven, Huntington, Islip, and Smith Town	0.6 MAX
   Erie and Niagara Counties	1.7 MAX, 1.4 AVG*
   Remainder of State	2.5 MAX, 1.9 AVG*, and 1.7 AVG (ANNUAL)**

   * Averages are computed for each emission source by dividing the total sulfur content by the total gross heat content of all solid fuel received during any consecutive three-month period.

   ** Annual averages are computed for each emission source by dividing the total sulfur content by the total gross heat content of all solid fuel received during any consecutive 12-month period.

3. (c) Owners and/or operators of any stationary combustion installation that fires residual oil are limited to the firing of residual oil with a sulfur content listed in the table below. On and after July 1, 2023, all emission sources, including process and incineration sources that fire residual oil, are limited to the firing of residual oil with a sulfur content listed in the table below:

   Area	Residual oil (percent sulfur by weight)
   New York City	0.30
   Nassau, Rockland and Westchester Counties	0.37
   Remainder of State	0.50

4. (d) Owners and/or operators of any emission source that fires distillate oil are limited to the firing of distillate oil with 0.0015 percent sulfur by weight or less. On and after July 1, 2023, all emission sources, including process and incineration sources that fire distillate oil, are limited to the firing of distillate oil with 0.0015 percent sulfur by weight or less.
5. (e) Owners and/or operators of any emission source that fires waste oil are limited to the firing of waste oil with 0.75 percent sulfur by weight or less. On and after July 1, 2023, owners and/or operators of any emission source that fires waste oil are limited to the firing of waste oil with 0.25 percent sulfur by weight or less.

No person will sell, offer for sale, purchase, or fire any fuel and/or waste oil that exceeds the sulfur-in-fuel limitations of this section, except as provided in section 225-1.3 or 225-1.4 of this Subpart. For the purposes of this Subpart, liquid bio-fuels, other than waste oils, are required to meet the sulfur-in-fuel standards of distillate oil.
