Dear Andy,

The Solid Waste Section (Section) has reviewed your request to abandon MW-15 at the Macon Co MSW Landfill due to it being damaged. The Section took into account the historical
groundwater results and location of MW-15. The groundwater results don’t indicate any exceedances and the location of the well is side gradient of the current cell. Based on these
facts, the Section approves the abandonment of MW-15 and to permanently remove it from the groundwater monitoring well network. The facility shall submit a well abandonment
form GW-30 upon completion of the well abandonment. Please don’t hesitate to contact me with any questions or concerns.

Sincerely,
Elizabeth

Subject: MW-15 at Macon County Landfill (Permit 57-03)

Hello Elizabeth,

Chris Stahl at Macon County asked me to contact you about groundwater monitoring well MW-15. Macon County’s grading
contractor (Shamrock) recently damaged the MW-15. The disposition of the well is unknown this time because it’s currently covered
with soil. Macon County plans to have Shamrock uncover the well this week.

We understand from Mike Hofe (REIC) that MW-15 typically has 1 to 2 feet of water and is sometimes dry. We also understand that
metals are the only constituents typically detected in MW-15. Mike can provide more details if requested.

We need to ask SWS a few questions about the future of MW-15.

1) We don’t anticipate that we will be able to save MW-15. Once the well is uncovered, we would like SWS approval to abandon
the well (in accordance with the approved WQMP, GW-30 form and submittal by BLE).
2) If SWS approves the abandonment, we would like to permanently remove MW-15 from the monitoring matrix (not replace the
well).
3) If SWS requires the replacement of MW-15 we would like to install it about 10 feet deeper and perform the installation at the
time the 3 new monitoring wells (MW-24, MW-25, and MW-26) are installed for Phase 3 Cell 1. It would not be cost effective for
the county to install a single well.

I’ve pasted an image of the map from the WQMP that shows the location of MW-15 for your reference. Thanks and please let us
know your thoughts on our questions. --Andy
