1 INTRODUCTION

1.1 Project Summary

This report presents construction documentation of the landfill gas collection and control system (GCCS) components installed at the Clark-Floyd Landfill Recycling & Disposal Facility during the 2022 calendar year. The landfill, located in Borden, Indiana, is jointly owned by the Clark and Floyd Counties and operated by Clark-Floyd Landfill, LLC (CFL).

The following report summarizes the installation of GCCS components, quality control observations and record documentation of the construction. It needs to be noted that the piping and installation work documented in this report relates to interm conveyance and not final GCCS components as outlined in the GCCS design Plan submitted to IDEM , February 2012.

Further, with waste disposal operations being concentrated on the east phase of the landfill and with the upward landfill growth on the east phase, interim conveyance piping is constantly changing to work around waste disposal operations; therefore, interim conveyance piping is being modified monthly with the final changes occurring during December 2022.

CFL performed pipeline construction and provided the as-built survey information for this report. These were used by Cornerstone to prepare the GCCS record drawings of the construction.

The construction involved the following:

Installation of replacement sections of header/laterals; and Construction of airlines and forcemains.

1.2 Reference Documents

The following documents were utilized fo the 2022 GCCS Construction Certification Report:

Drawing titled: “Landfill Gas Collection and Control System – 2022 As-Built”, one (1) sheet, dated 1/26/2023, produced by Tetra Tech.

2 LANDFILL GAS COLLECTION AND CONTROL SYSTEM

2.1 Summary of CQA Services

CFL provided CQA services during the 2022 GCCS construction. Cornerstone has toured the eastern half of the landfill and reviewed the as-built interim gas conveyance piping to confirm locations.

The installed and modified interim gas conveyance components consisted of:

Pipe Installation in the wellfield o 10-inch diameter SDR 17 HDPE solid header/lateral pipe totaling approximately 2,071 feet;

o 6-inch diameter SDR 17 HDPE solid header/lateral pipe totaling approximately 185 feet;

o 4-inch diameter SDR 11 HDPE solid lateral pipe totaling approximately 210 feet; and o 3-inch diameter SDR 11 HDPE solid lateral pipe totaling approximately 311 feet.

Pipe Removed/Abandoned in the wellfield o 6-inch diameter HDPE SDR 17 solid lateral pipe totaling approximately 1,500 feet.

2.2 GCCS Construction Components

2.2.1 Pipeline Configuration

As depicted on the Record Drawings included with this report, new interim, header and lateral piping were installed at several locations.

o A new, interim 10-inch HDPE SDR 17 header was installed from a 90-degree elbow on the west side of Unit 1 to new well W1.9R.

o A new, interim 10-inch HDPE SDR 17 header was installed in Unit 1 from W1.9R to a Tee – continuing west to well W1.2R and east to well W1.4R.

o A new, interim 10-inch HDPE SDR 17 lateral was installed in Unit 1 from W1.4R to well W1.8RR.

o A new,interim 6-inch HDPE SDR 17 lateral was installed in Unit 1 from the new 10” header to well WW 03.

o A new,interim 4-inch HDPE SDR 17 lateral was installed in Unit 1 from the new 10” header to well W1.10.

o A new, interim 10-inch HDPE SDR 17 header was installed in Unit 2 from near well W2.5 to well W2.6.

o A new, interim 4-inch HDPE SDR 17 lateral was installed in Unit 2 from well W2.6 to a point between well W2.6 and well W2.9. A new, interim 3” HDPE SDR 11 lateral was installed from the end of the 4” lateral to well W2.9.

o A new, interim 3-inch HDPE SDR 17 lateral was installed in Unit 2 from a point between well W2.11 and well W2.7 to well W2.8.

o A new, interim 3-inch HDPE SDR 17 lateral was installed in Unit 2 from a point between well W2.11 and well W2.7 to well W2.8.

o A new, interim 3-inch HDPE SDR 17 lateral was installed in Unit 2 from a the new 10” header to well W2.5.

o A new, interim 3-inch HDPE SDR 17 lateral was installed in Unit 2 from a the new 10” header to well W2.6.

2.2.2 Condensate Management

LFG condensate from the newly installed, interim GCCS lateral pipes drain to existing header pipes and to existing condensate sumps.

3 SUMMARY AND CONCLUSIONS

Cornerstone has compiled and reviewed the documentation of the 2022 as-built GCCS, as constructed by CFL, in accordance with the GCCS Design Plan (dated February 2012) for the Clark-Floyd Landfill. This report provides documentation describing the extent and details of the GCCS construction.

No final gas collection portion of the system was installed during this calendar year. Future final collection system components will be installed in general accordance with the GCCS design plan and permit drawings approved by IDEM in August 2011. A Record Drawing of the GCCS layout is included in Appendix A. Final conveyance piping will be installed at this landfill as it approaches final grades and will likely be installed as part of cap installation so the piping can be accessed without damaging geosynthetic components of the cap system.
