# 62.15870 If my SSI unit is not listed on the federal plan inventory, am I exempt from this subpart?

Not necessarily. Sources subject to this subpart include, but are not limited to, the inventory of sources listed in Docket ID Number EPA-HQ-OAR-2012-0319 for the federal plan. Review the applicability of § 62.15855 to determine if you are subject to this subpart.
