PROPOSAL SUMMARY GREDELL E Eng ngine ineering ing R Resources, I Inc nc.

SUMMARY § Reduced number of wells 44 - 33 Samples collected from 24 wells § 3 Sentinel wells rather than 1 § § Reduced the number analytes Analysis required for Geochemicals, VOC’s, & 2 Metals § Full Appendix II analysis required every fifth year § § Reduced surface water analysis Sample number 4 – 2 § Frequency quarterly to semi-annual § Improved the list of analytes § GREDELL E Eng ngine ineering ing R Resources, I Inc nc.

SUMMARY Reduced clients annual GW sampling and analysis cost from $77,500 to $51,500 for a savings of $26,000. Surface water savings of approx. $5,000. Total Savings of $ 31,000 annually GREDELL E Eng ngine ineering ing R Resources, I Inc nc.

SUMMARY ADDITIONAL SAVINGS Reduced PC reserves from $72,500 to $40,000 At a 2% premium rate, approximately $650 in annual savings or $36,750 over 25 years of remaining active life and 30 years Post-Closure Compounded over 55 years that increases to a range of $75,000 - $130,000 depending on the rate of inflation GREDELL E Eng ngine ineering ing R Resources, I Inc nc.
