3.        If an owner or operator of a fossil-fuel fired steam gener- ator obtained an installation permit for two or more fuel- burning equipment or steam-power generating installa- tions before May 14, 1979, that permitted the installation to comply with the sulfur dioxide emission standards specified in R18-2-901 and this Section as if the equip- ment or installations were one emission discharge point:

a.         The owner or operator shall comply with the appli- cable sulfur dioxide emission standards in the man- ner specified in the installation permit;

b.        The Department shall incorporate the emission stan- dards under subsection (3)(a) into each owner’s or operator’s operating permit as an enforceable permit condition;

c.       No single fuel-burning equipment or steam-power generating installation shall emit sulfur dioxide in excess of:

i.         520 nanograms per joule heat input (1.2 pounds per million BTU) for solid fossil fuel or solid fossil fuel and wood residue; or

ii.        340 nanograms per joule heat input (0.8 pounds per million BTU) for liquid fossil fuel or liquid fossil fuel and wood residue.

4.        When an owner or operator subject to subsection (3) changes the equipment configuration so that each fuel- burning equipment or steam-powered generating installa- tion constitutes one emission discharge point:

a.         The owner or operator shall comply with the emis- sions standards specified in subsection (1) and R18- 2-901; and

b.        The Department shall incorporate the emissions standards into the owner’s or operator’s operating permit as enforceable permit conditions.
