system ends at the truck loading station or similar equipment that transfers the ash to final disposal. The SSI unit does not include air pollution control equipment or the stack.
Section 129 mandates that all plan requirements be at least as protective as the promulgated emission guidelines.
This includes fixed final compliance dates, fixed compliance schedules, and title V permitting requirements for all affected sources. Section 129 also requires that state plans be submitted to EPA within one year after EPAs promulgation of the emission guidelines and compliance times.
States have options other than submitting a state plan in order to fulfill their obligations under CAA sections 111d and 129. If a state does not have any existing SSI units for the relevant emission guidelines, a letter can be submitted certifying that no such units exist within the state i.e., negative declaration in lieu of a state plan, in accordance with 40 CFR 60.5010. The negative declaration exempts the state from the requirements of subpart B that would otherwise require the submittal of a CAA section 111d/129 plan.
On March 21, 2011 76 FR 15372, EPA finalized emission guidelines for SSI units at 40 CFR part 60, subpart MMMM. Following the 2011 final rule, MDE determined that there was one SSI
facility in Maryland that met the applicability criteria for the Federal plan. On January 20, 2017, MDE
submitted a letter to EPA requesting full delegation of authority to implement the SSI Federal plan. However, that facility has now permanently shut down and has relinquished its title V permit to operate. Accordingly, MDE sent a negative declaration for SSI units on April 3, 2020.
II. Final Action In this action, EPA amends 40 CFR
part 62 to reflect receipt of the negative declaration letter from MDE, received April 3, 2020, certifying that there are no existing SSI units subject to 40 CFR
part 60, subpart MMMM, in accordance with section 111d and 129 of the CAA.
EPA is accepting the negative declaration in accordance with the
