# §60.5060. What SSI units must I address in my state plan?

- (a) Your state plan must address SSI units that meet all three criteria described in [paragraphs (a)(1) through (3)](#a-1..a-3) of this section.
  - (1) **SSI units in your state that commenced construction on or before October 14, 2010.**
  - (2) SSI units that meet the definition of a SSI unit as defined in [§ 60.5250](/cfr/40/60.5250.md).
  - (3) SSI units not exempt under [§ 60.5065](/cfr/40/60.5065.md).
- (b) If the owner or operator of a SSI unit makes changes that meet the definition of modification after September 21, 2011, the SSI unit becomes subject to [subpart LLLL](/cfr/40/subpartLLLL.md) of this part and the state plan no longer applies to that unit.
- (c) If the owner or operator of a SSI unit makes physical or operational changes to a SSI unit for which construction commenced on or before September 21, 2011 primarily to comply with your state plan, [subpart LLLL](/cfr/40/subpartLLLL.md) of this part does not apply to that unit. Such changes do not qualify as modifications under [subpart LLLL](/cfr/40/subpartLLLL.md) of this part.
