<br />Q3 Corrective Action Program Update - 2025
<br />
<br />EXTRACTION WELLS
<br />SCS continued performing operation and maintenance of the GCCS including extraction wells
<br />monitoring and tunning, pipe maintenance, condensate management system inspection and
<br />maintenance.
<br />Extraction wells monitoring data for the quarter are provided in Table 2 1.
<br />CONCLUSION
<br />Based on the data collected by SCS, the monitoring, testing, and inspection of the GCCS conducted
<br />during the third quarter of 2025 met the CAO requirements for the operation and maintenance of
<br />the GCCS at the Landfill. Moreover, since the Quarter 2 of 2025, Forward has increased the
<br />number of gas wells at the Landfill from 248 to 274 to address LFG migration; with two extraction
<br />wells particularly located close to GP-10 to minimize methane detections at the GP-10 monitoring
<br />probes.
<br />Please contact the undersigned if you have any questions or comments.

<br />installed; the total number of LFG extraction wells operating at this time is greater than the number in the WDR.
<br />
<br />As of this reporting period, Forward operates 274 LFG wells (see Table 2).
<br />
<br />As of this reporting period, the abandoned wells include A12-06D, A12-12S, A14-11, A16-13, A17-07, A17-09S,
