# §52.1085. Interstate pollutant transport provisions; What are the FIP requirements for decreases in emissions of sulfur dioxide?

- (a) The owner and operator of each source and each unit located in the State of Maryland and for which requirements are set forth under the CSAPR SO2 Group 1 Trading Program in [subpart CCCCC of part 97](/cfr/40/part97-subpartCCCCC.md) of this chapter must comply with such requirements. The obligation to comply with such requirements will be eliminated by the promulgation of an approval by the Administrator of a revision to Maryland's State Implementation Plan (SIP) as correcting the SIP's deficiency that is the basis for the CSAPR Federal Implementation Plan under [§ 52.39](/cfr/40/52.39.md), except to the extent the Administrator's approval is partial or conditional.
- (b) Notwithstanding the provisions of [paragraph (a)](#a) of this section, if, at the time of the approval of Maryland's SIP revision described in [paragraph (a)](#a) of this section, the Administrator has already started recording any allocations of CSAPR SO2 Group 1 allowances under [subpart CCCCC of part 97](/cfr/40/part97-subpartCCCCC.md) of this chapter to units in the State for a control period in any year, the provisions of [subpart CCCCC of part 97](/cfr/40/part97-subpartCCCCC.md) of this chapter authorizing the Administrator to complete the allocation and recordation of CSAPR SO2 Group 1 allowances to units in the State for each such control period shall continue to apply, unless provided otherwise by such approval of the State's SIP revision.
