Report #1 - May 24, 2017 ReUse Technology, Inc. Former Swift Creek Coal Combustion By Product (CCB) Structural Fill, CCB0057 Battleboro, North Carolina Introduction   ERM NC, Inc. (ERM) has been contracted by ReUse Technology, Inc. (ReUse) to implement the Groundwater Corrective Action Plan for the Former Swift Creek Coal Combustion By Product (CCB) Structural Fill, CCB0057 approved by NCDEQ – Division of Waste Management on March 12, 2015. As requested by NCDEQ, ERM will provide monthly updates to summarize site activities including any changes in conditions as the project progresses. ERM has subcontracted Earnhardt Grading, Inc. (Earnhardt) of Lowesville, North Carolina to provide site preparation, excavation, grading, geosynthetic installation and final site stabilization. ERM and Earnhardt have been on the Swift Creek site full time beginning April 24, 2017 for construction activities. ERM has compiled weekly update status reports that are attached for reference. Summary of Activities On April 24, 2017, ERM and Earnhardt arrived on site to begin site preparation activities. These activities included:  Conduct onsite Pre-Construction Meeting (sign in sheet attached).  Review of site specific health & safety plans; ERM plan and Earnhardt plan; to identify unexpected changes in conditions.  Review public and third party utility location surveys and identify in the field.  Install erosion and sedimentation control measures per NCDEMLR – Division of Land Quality approved plans (approved March 31, 2017).  Establish field office trailer and parking area for project.  Abandon piezometers previously installed in the project footprint.  Strip and stockpile topsoil on site for future use.  Strip and stockpile cover soils on site for future use. During installation of the approved sediment basins; SB-1 in the northwest corner of the site and SB-2 along the northeast side of the site; CCB materials were identified within the basin footprint areas. Under the full time observation of ERM, Earnhardt removed these materials from the basin areas using a “long reach” tracked excavator and transporting with off road articulating dump trucks (ADT’s). The soil layer beneath these materials in the basin areas is a ERM NC, Inc. 15720 Brixham Hill Avenue Suite 120 Charlotte, NC 28277 (704) 541-8345 (704) 541-8416 (fax) Swift Creek Monthly Update Report #1 Page 2 May 24, 2017 light gray/white sandy clay/clayey sand for identification purposes. The CCB materials were transported to an area towards the middle of the site stripped of cover soils and surrounded with an earthen berm to incorporate into the final closure footprint. An estimated 4,290 cubic yards (CY) of material was removed from these basins combined. No CCB materials were encountered in the southern basin SB-3. Following installation of erosion and sedimentation control measures, Earnhardt subcontracted McCall Brothers, Inc. of Charlotte, NC (a certified NC well driller) to perform abandonment of piezometers within the corrective action plan footprint that extend beyond the bottom of CCB materials. The remainder will be removed during excavation of the CCB materials in the Phase 1 Area. ERM has not received the well abandonment records to date but will include in the next monthly update report. Earnhardt has stripped the topsoil and cover soils from within the CCB site area and stockpiled in the southern basin area located south of the CCB footprint. This stockpile area was included on the approved Corrective Action Plan and the approved Erosion & Sedimentation Control Plan. At the end of this first month of construction activities, Earnhardt has started excavation of CCB materials from the southern end of the site (Phase 1) transporting to the northern half of the site (Phase 2). Site Observations  To date there have been no visual indications of dust migration off site.  Since arriving on site, approximately 12-inches of rain has been recorded based on the onsite rain gage and monitoring. 2.75 inches recorded from May 22nd to May 23rd.  Erosion and sedimentation control measures are functioning appropriately and there have been no observations of offsite sediment releases.  Monitoring wells have been marked with construction fence and maintained throughout construction activities.

There were no technical questions from the Division and an onsite meeting will be scheduled over the next several weeks. Project Related 2. Earnhardt Grading and ERM mobilized to the project on 4/24/17. ERM conducted a pre-construction meeting with Earnhardt to review the project and schedule. Due to heavy rains Monday and Tuesday, site activities have been limited to date. 3. Earnhardt Grading is focusing on installation of erosion and sedimentation control measures along with site office and stabilized entrance development. Two (2) Week Look Ahead (4/26/17 – 5/10/17): 4. Earnhardt and ERM will remain on site full time. 5. Next week will focus primarily on reviewing Health& Safety Plans on site, installing erosion and sedimentation control measures and becoming familiar with surroundings. 6. Earnhardt will establish an onsite field office trailer with utility service. 7. Public utility “mark out” is complete and private utility “mark out” is scheduled to be completed by Wednesday April 26th. 8. Once Erosion and Sedimentation Control measures are in place, ERM will notify NCDEMLR and schedule a site visit for compliance. 9. ERM will continue to update Full Circle concerning site activities.   ReUse Technology, Inc. Swift Creek Project Weekly Update – May 3, 2017 Key Items Completed Last Week: Permit Related 1.
