Background Information

The year 2020 was the sixth year of compliance for the CSAPR SO₂ (Group 1 and Group 2), NOₓ Annual and NOₓ Ozone Season Group 1 programs, while it was the fourth year of compliance for both the CSAPR NOₓ Ozone Season Group 2 program and CSAPR Update. Each program has its own distinct set of allowances, which cannot be used for compliance with the other programs (e.g., CSAPR SO₂ Group 1 allowances cannot be used to comply with the CSAPR SO₂ Group 2 Program). Each CSAPR trading program contains “assurance provisions” to guarantee that each covered state achieves the required emissions reductions. If a state’s covered units exceed the state’s assurance level under the specific trading program, then the state must surrender two allowances for each ton of emissions exceeding the assurance level.

The compliance summary emissions number cited in “Highlights” may differ slightly from the sums of emissions used for reconciliation purposes shown in the “Allowance Reconciliation Summary” figures because of variation in rounding conventions, changes due to resubmissions by sources, and compliance issues at certain units. Therefore, the allowance totals deducted for actual emissions in those figures differ slightly from the number of emissions shown elsewhere in this report.
