Negotiation Summary

TO: HW687 Contract File FROM: Dean Cox, Contract Manager SUBJECT: DC011D 60 Minute Cleaners (ERIC_4806) O&M (12 months)

DATE: 6/30/23

This TA authorizes costs associated with SVE system O&M. The total cost of this TA is $15,041.43. There is $6,000 in cost reimbursement included in the total cost. This TA was negotiated - the total cost is $17,008.34 or 53% less than originally proposed.

This SVE system is operating for methane mitigation only. A separate groundwater monitoring (PARM/Post-ISB) TA will be executed, which will include dissolved gases and UIC parameters sampling. The previous groundwater sampling event completed in 2022 indicated dissolved methane above 10 mg/L and UIC parameters above RAP thresholds. Groundwater PCE levels remained moderate in this event, with a high of 8,900 ug/L.

The last month of O&M in the previous (DC011B) O&M TA is June 2023. There is enough utilities money in the previous O&M TA to cover July utilities and that TA does not expire until the end of July. Site access was confirmed.
