SUPPLEMENTARY INFORMATION:
Throughout this document we, us, and our means the EPA.
I. Background The background for this action is discussed in detail in our March 26, 2021 proposed rule 86 FR 16173. In that document we proposed to approve the North Dakota CAA section 111d state plan for existing MSW landfills and the North Dakota CAA section 111d/129 state plan for existing CISWI

document also proposed approval of the North Dakota withdrawal of a previously approved CAA section 111d/129 state plan for existing HMIWI units and publication of the States negative declaration of existing HMIWI units in lieu of a state plan. The EPAs analysis of the two North Dakota state plans and the negative declaration of designated sources may be found in the aforementioned proposed rule and the technical support document TSD
associated with the docket for todays action. Comments on the EPAs proposed approvals of the state plans for existing CISWI units and MSW landfills and approval of the negative declaration in lieu of a state plan for existing HMIWI units were due on or before April 26, 2021. We received no comments on our proposed actions.
Therefore, the EPA will proceed with these plan approvals without changes.
II. Final Action The EPA is finalizing approval of the North Dakota section 111d state plan for existing MSW landfills pursuant to 40 CFR part 60, subparts B and Cf. We are also finalizing approval of the North Dakota section 111d/129 state plan for existing CISWI units pursuant to 40 CFR
part 60, subparts B and DDDD. Finally, we are finalizing approval of the States negative declaration of existing HMIWI
units in lieu of a state plan for such units as designated by 40 CFR part 60, subpart Ce. Therefore, the EPA is amending 40 CFR part 62, subpart JJ to reflect this approval action. This approval is based on the rationale provided in section II of the proposed rule for this action 86 FR 16173 and discussed in detail in the TSD
associated with this rulemaking action.1
The scope of this approval is limited to the provisions of 40 CFR parts 60 and 62. The EPAs proposed approval of the two North Dakota plans is limited to those MSW landfills that meet the criteria established in 40 CFR part 60, subparts Cf and those CISWI units and ACI units that meet the criteria 1 EPA Document ID No. EPAR08OAR2021
