 Tests are performed every 5 years. It is assumed the state or agency will review the data in the ensuing periodic report, unless a problem is detected.

Notes:

* The Application Factor is a percentage between 0% and 100% that represents the Agency's best estimate of the number of operators, or the extent to which all operators, would 

engage in a given compliance activity; it takes into account those aspects of the rule that allow for operator and Director discretion and general trends in the CO2GS industry in terms of 

methods or equipment used.

 Sub-section 146.82(c) includes the following information: All available logging and testing program data on the well; A demonstration of mechanical integrity pursuant to §146.89; the 

anticipated maximum injection pressure and flow rate; the results of the formation testing program; the actual injection procedure; the compatibility of the carbon dioxide stream with 

fluids in the injection zone and minerals in both the injection zone and the primary confining system and secondary containment system; the status of corrective action on deficient wells 

in the area of review.

1 Injected volumes are discounted to the first year of the analysis and annualized over 25 years at 3% discounting for comparability to annualized costs. 2 Injected volumes are discounted to the first year of the analysis and annualized over 25 years at 7% discounting for comparability to annualized costs. 3"Number of projects deployed" in above table is based on RA3 (and RA1 and RA2, which are identical in #projects); since under RA0 and RA4 no waivers are allow

projects for which a waiver would be sought are assumed not to go forward under RA0 and RA4, resulting in a slightly lower number of projects moving forward undescenarios as compared to RA1, RA2, and RA3. This difference ultimately is the 5% that are approved for waiver under RA1, RA2, and RA3. 4Because Large Saline Waivered and ER Waivered projects don't exist under RA0, the annualized incremental rule cost per metric tonne is equal to the total project tonne for those two project types.
