Scenario #1 @7% discount rate = $5,560 $84,489 $2,224 $33,796 $890 $13,518<br />
6. CCR Impoundment Failure Costs Avoided<br />
If Based on Extrapolated Recent Failure Cases $1,762 $793 $405<br />
If Based on 10% Future Failures $8,366 $3,795 $1,897<br />
If Based on 20% Future Failures $16,732 $7,590 $3,795<br />
7. Non-quantified Benefits*** Q R S<br />
Total Benefits (4+5+6):<br />
Total Benefits w/Extrapolated Recent Failure Cases = $8,292 $87,221 $3,392 $34,964 $1,483 $14,111<br />
Total Benefits @10% Future Failures = $14,896 $93,825 $6,394 $37,966 $2,975 $15,603<br />
Total Benefits @20% Future Failures = $23,262 $102,191 $10,189 $41,761 $4,873 $17,501<br />
Net Benefits (Total Benefits minus Total Costs)<br />
Net Benefits w/Extrapolated Recent Failure Cases = ($12,057) $66,872 ($4,703) $26,869 ($1,776) $10,852<br />
Net Benefits @10% Future Failures = ($5,453) $73,476 ($1,701) $29,871 ($284) $12,344<br />
Net Benefits @20% Future Failures = $2,913 $81,842 $2,094 $33,666 $1,614 $14,242<br />
Benefit/Cost Ratio (BCR)<br />
BCR w/Extrapolated Recent Failure Cases = 0.407 4.286 0.419 4.319 0.455 4.330<br />
BCR @10% Future Failures = 0.732 4.611 0.790 4.690 0.913 4.788<br />
BCR @20% Future Failures = 1.143 5.022 1.259 5.159 1.495 5.370<br />
Notes:<br />
* Cancer risk reflects the arsenic groundwater pathway only and does not include other human health mortality or morbidity risks from non-carcinogens, nor do they<br />
reflect ecological and socio-economic damages that could occur. Thus, the benefits are underestimated in this RIA.<br />
** Cancer risks avoided are based on National Academy of Science (2001) data, which represents recent scientific in<strong>for</strong>mation.<br />
*** Q>R>S; For example, non-quantified ecological benefits could add 159%, and socio-economic benefits could add 24%, compared to avoided cleanup cost benefit.<br />
