Report #7 – November 30, 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 Since the previously issued Monthly Project Update dated October 24, 2017, ERM and Earnhardt Grading have remained onsite full time conducting corrective action plan activities. These activities included:  Removal of CCB materials from the north end (Phase 2 area) of the project site.  Placing CCB materials on the south end raised floor (Phase 1) area of the project site.  Achieving final proposed grades for the south end CCB materials closure.  Installation of 40-mil Linear Low Density Polyethylene (LLDPE) liner over the entire CCB closure footprint.  Installation of double sided 6-ounce drainage geocomposite above the 40-mil liner.  Installation of liner system anchor trench, perforated pipe, anchor trench drains and backfilling with washed stone (95% complete).  Importing of offsite soils for protective final cover over the liner system.  Maintaining erosion and sedimentation control measures per NCDEMLR – Division of Land Quality approved plans (approved March 31, 2017).  Surveying as-builts for removal of CCB materials and finished closure footprint grades. At the end of this seventh month of construction activities, Earnhardt has completed 100% of the liner system installation. Due to heavy rains in the vicinity of the project, there have been several days lost to production due to weather and/or wet conditions.
