Interim White Paper - Midwest RPO Candidate Control Measures

3/10/2006 Page 3

TABLE 1b – CONTROL MEASURE SUMMARY FOR GDFs – STAGE II

Control Measure Summary

VOC Emissions (tons/year) in 5-State MRPO Region

2002 existing measures: Stage II vapor recovery systems in moderate, serious, and severe for 1- hour ozone nonattainment areas 2009 On-the Books measures: Use of on-board refueling vapor recovery (ORVR) canisters to capture and adsorb vapors from the vehicle fuel tank. ORVR is required to be installed on some new vehicles in 1998, and all new vehicles will be required to have ORVR installed by 2006. Candidate measure: Adopt CARB EVR Stage II requirements in 8- hour nonattainment areas and adjacent counties Measure ID: SOLV7B Emission Reductions: reduction of 46-91% from 2002 levels depending on the geographic coverage Control Cost: $36,260 per ton to upgrade existing systems to meet CARB EVR Phase II requirements; about $13,300 for new Stage II systems in 2009, increasing to $28,500 by 2015 Timing of Implementation: Assuming 2007 effective date of rule, emission reductions are achieved in 2011 with CARB’s four-year window for existing facilities to upgrade equipment Implementation Area: (1) 8-hr ozone nonattainment areas, (2) 8-hr ozone nonattainment areas plus adjacent counties, or (3) all counties in MRPO region

2002 Base:

44,815

2009 Reduction:

-23,312

2009 Remaining:

21,503

2002 Base:

44,815

2002 Base:

44,815

2009 Reduction:

-40,550

2009 Remaining:

4,265

Notes: 2009 and 2011 emission reductions shown are reductions for 2002 base emissions, assuming that control measures are implemented in all counties; 2009 and 2011 emissions are not growth-adjusted.

Disclaimer: The control measures identified in this document represent an initial set of possible measures. The Midwest RPO States have not yet determined which measures will be necessary to meet the requirements of the Clean Air Act. As such, the inclusion of a particular measure here should not be interpreted as a commitment or decision by any State to adopt that measure. Other measures will be examined in the near future. Subsequent versions of this document will likely be prepared for evaluation of additional potential control measures.
