# §60.6300. What municipal waste combustors must I address in my state plan?

- (a) Your state plan must address all existing large municipal waste combustors in your state that meet two criteria:
  - (1) The municipal waste combustor has the capacity to combust greater than 250 tons per day of municipal solid waste.
  - (2) **The municipal waste combustor commenced construction on or before January 23, 2024.**
- (b) If an owner or operator of a municipal waste combustor makes changes that meet the definition of modification or reconstruction after September 10, 2026 for [subpart VVVV](/cfr/40/subpartVVVV.md) of this part, the municipal waste combustor becomes subject to [subpart VVVV](/cfr/40/subpartVVVV.md) of this part and the state plan no longer applies to that unit.
- (c) If an owner or operator of a municipal waste combustor makes physical or operational changes to an existing municipal waste combustor primarily to comply with your state plan, [subpart VVVV](/cfr/40/subpartVVVV.md) of this part (Standards of Performance for Large Municipal Waste Combustors) does not apply to that unit. Such changes do not constitute modifications or reconstructions under [subpart VVVV](/cfr/40/subpartVVVV.md) of this part.
- (d) If an owner or operator of a municipal waste combustor meets the applicability requirements of this section, the unit is not subject to subparts Db or E of this part.
