Program Compliance Tables
Last updated: 05/2016
ARP and CAIR SO₂ Programs
- The reported 2014 SO₂ emissions by CAIR and ARP sources totaled 3,155,031 tons.
- Over 33 million SO₂ allowances were available for compliance under both programs (9 million vintage 2014 and over 24 million banked from prior years).
- Just over 3.1 million allowances were deducted for ARP compliance and an additional 2.3 million allowances were deducted to complete reconciliation for CAIR. After reconciliation for both programs, over 27.7 million ARP SO₂ allowances were banked and carried forward to the 2015 ARP compliance year.
- All ARP and CAIR SO₂ facilities were in compliance for both programs in 2014 and held enough allowances to cover their SO₂ emissions.
CAIR NOₓ Annual Program
- The reported 2014 annual NOₓ emissions by CAIR sources totaled 1,164,280 tons.
- All covered facilities were in compliance with the CAIR NOₓ annual program in 2014 and held enough allowances to cover their NOₓ emissions.
CAIR NOₓ Ozone Season Program
- The reported 2014 ozone season NOₓ emissions by CAIR sources totaled 448,991 tons.
- All covered facilities were in compliance with the CAIR NOₓ ozone season program in 2014 and held enough allowances to cover their NOₓ emissions.
Analysis and Background Information
The year 2014 was the fifth and final year for compliance with the CAIR SO₂ program. Under this program, allowances are used to cover emissions based on the vintage year of the allowances, with pre-2010 vintage allowances used at one allowance for 1 ton of SO₂ emissions, and 2010—2014 vintage allowances used at two allowances for 1 ton of SO₂ emissions. For facilities covered by both CAIR and the ARP, reconciliation is a two-step process. First, ARP deductions are made; then, any additional deductions to comply with the CAIR SO₂ program are made. The additional deductions under CAIR could be used to cover the two-for-one use of 2010—2014 allowances or to cover emissions for units that are subject to CAIR, but not the ARP.
Because of variation in rounding conventions, changes due to resubmissions by sources, and allowance compliance issues at certain units, the compliance summary emissions number cited in "Key Points" may be lower than the sums of emissions used for reconciliation purposes shown in the "Allowance Reconciliation Summary" figures. Therefore, the allowance totals deducted for actual emissions in those figures differ from the number of emissions shown elsewhere in this report.
