EXECUTIVE SUMMARY The South Glenburnie Road Site/ Clarke Power Services Site (Brownfields Project Number 20061-16-025) is located at the southwest intersection of South Glenburnie Road and ML King Jr. Boulevard in New Bern, Craven County, North Carolina. Land use in the area is comprised of a mixture of commercial and residential properties. Currently, approximately 31.62 acres owned by multiple entities are being acquired by CDG-New Bern, LLC (CDG) for re -development into a retail shopping center. In May 2015, during a Phase I Environmental Site Assessment (ESA), several Recognized Environmental Concerns were identified which included historical heating oil USTs and ASTs located at the six residences located on Trent Road. Subsequently, in November 2015, during Phase II ESA activities, temporary monitoring wells were installed and ground water samples were collected from the residences. Laboratory results confirmed ground water contamination at 3704 and 3706 Trent Road. On November 30, 2016, Geological Resources, Inc. directed soil excavation in the location of the former temporary monitoring well at 3704 Trent Road. Impacted soil was observed in the saturated zone of the excavation, approximately 8 to 10 feet below ground surface (BGS). The final excavation was approximately 11 feet wide by 11 feet long by 12 feet deep. The excavation basin was de -watered prior to filling it with clean regional sand. On November 30 and December 1, 2016, at 3706 Trent Road, soil was excavated in the location of the former monitoring well and the hydraulic lift was excavated and removed. Impacted soil was observed in the saturated zone approximately 7 to 11 feet BGS. The final excavation was approximately 17 feet long by 14 feet wide by 12 feet deep. The excavation basin was de -watered prior to filling it with clean regional sand. On December 5, 2016, four soil samples were collected from the perimeter of the excavation areas; and, one soil sample was collected in the former location of the hydraulic lift located at 3706 Trent Road. Soil samples were analyzed using EPA Methods 8260 and 8270. Estimated concentrations of acetone, methyl cyclohexane, and/or 1,2,4 trimethylbenzene were reported in three soil samples. However, none of the estimated concentrations exceeded the Preliminary Soil Remediation Goals for protection of ground water or Industrial Health. On December 2, 2016, subsequent to excavation activities, temporary monitoring wells were installed at 3704 and 3706 Trent Road. Ground water samples were collected and submitted for laboratory analysis using SW 846 8260B and 8270B. Estimated concentrations of 1-methylnaphthalene, 2- methylnaphthalene, and 1,2,4 trimethylbenzene were reported in ground water samples collected from 3706 Trent Road. However, none of the estimated concentrations exceeded the Maximum Allowable Concentrations or the non-residential Ground Water Screening Levels for Vapor Intrusion Based on these data, there are no soil violations or vapor intrusion conditions at 3704 or 3706 Trent Road.

Currently, the area is owned by multiple entities; however, CDG-New Bern, LLC (CDG) is in the process of acquiring them. Subsequent to their acquisition, CDG intends to remove existing buildings and re- develop the Site into a retail shopping center. In May 2015, ECS Carolinas LLP conducted a Phase I Environmental Site Assessment (ESA) at the South Glenbumie Properties and identified Recognized Environmental Concerns (RECs) that included historical heating oil USTs and ASTs located at six Trent Road Residences. In November 2015, as part of the Phase II ESA activities, Geological Resources, Inc. (GRI) collected ground water samples from the Trent Road residences. Concentrations of naphthalene, 1- methylnaphthalene and 2- methylnaphthalene reported in ground water samples collected from 3704 Trent Road and 3706 Trent Road exceeded the Maximum Allowable Concentrations (MACS). Concentrations of naphthalene and/or 1,2,4 trimethylbenzene exceeded the non-residential Ground Water Screening Levels (GWSLs) for Vapor Intrusion in samples collected at 3704 and 3706 Trent Road. In order to reduce the ground water contamination and remove concern for vapor intrusion, soil excavation and dewatering activities were conducted at 3704 and 3706 Trent Road. Please refer to earlier reports for details pertaining to the Phase I ESA and Phase II ESA assessments. 2.0 EXCAVATION ACTIVITIES On November 30, 2016, the area in the former location of the ESA temporary well at 3704 Trent Road was excavated. Impacted soil was observed toward the house, in the saturated zone of the excavation, approximately 8 to 10 feet below ground surface (BGS). Soil was saturated approximately 5 to 6 feet BGS. The impacted soil was removed and the excavation remained open until the end of the work day when it was de -watered and filled with clean regional sand. The final dimensions of the excavation were approximately 11 feet long by 11 feet wide by 12 feet deep. The property owner was on -site during excavation activities. According to Mrs. Harrell, who lived in the house as a child, an AST was located in the excavation area. 1 On November 30 and December 1, 2016, the area in the former location of the ESA temporary well at 3706 Trent Road was excavated. Impacted soil was observed southeast of former temporary well location and extended toward the residence, in the saturated zone of the excavation, approximately 7 to 11 feet BGS. Soil was saturated approximately 5 to 6 feet BGS. The impacted soil was removed and the excavation remained open until the end of the work day when it was de -watered and filled with clean regional sand. During excavation, a 280-gallon UST was removed. The UST was pitted and in very poor condition. The final dimensions of the excavation were approximately 17 feet long by 14 feet wide by 12 feet deep. On December 1, 2016, the hydraulic lift located at 3706 Trent Road was removed. The lift was overlain by a concrete pad that was approximately 8 feet long by 8 feet wide and 6 inches thick. The lift cylinder extended into the subsurface approximately 3 feet and was in good condition upon removal. There were no visible signs of soil staining or leakage. The excavation area was limited to what was required to extract the hydraulic cylinder. The approximate excavation boundaries are shown on Figure 3. Copies of the soil and water disposal manifests will be forwarded upon receipt. Photographs of the excavation activities are included in Appendix A. 3.0 SOIL On December 5, 2016, four soil samples (SS-8 (3) through SS-11 (3)) were collected from the side walls of the excavation at 3704 Trent Road. Four soil samples (SS-12 (3) through SS-15 (3)) were collected from the side walls of the excavation at 3706 Trent Road and one soil sample (SS-16 (3)) was collected in the former location of the hydraulic lift. All soil samples were collected using a decontaminated hand -auger in general accordance with the EPA standard protocol. Soil samples were taken above the seasonal high water table, approximately 3 feet BGS. Soil samples were submitted for laboratory analysis using EPA Methods 8260 and 8270. All soil borings were properly abandoned subsequent to sample collection. Copies of the subsurface logs are included in Appendix B. Estimated concentrations of acetone, methyl cyclohexane, and/or 1,2,4 trimethylbenzene were reported in soil samples SS-9 (3), SS-11 (3), and SS-12 (3). However, none of the estimated concentrations exceeded the Preliminary Soil Remediation Goals (PSRGs) for protection of ground water or the PSRGs for Industrial Health. 2 A summary of ground water analytical results is presented in Table 1. Soil boring locations are shown on Figure 4. A copy of the laboratory report is included in Appendix C. 4.0 GROUND WATER On December 2, 2016, temporary monitoring wells MW-A and MW-B were installed at 3704 and 3706 Trent Road, respectively. The monitoring wells were installed to 13 feet below ground surface and were purged and sampled in general accordance with the EPA standard protocol. Ground water samples were submitted for laboratory analysis using SW 846 8260B and 8270B. Both temporary monitoring wells were properly abandoned subsequent to sample collection. Copies of the subsurface logs are included in Appendix B. No detectable concentrations were reported in samples collected from 3704 Trent Road (MW-A). Estimated concentrations of 1-methylnaphthalene, 2- methylnaphthalene, and 1,2,4 trimethylbenzene were reported in ground water samples collected from 3706 Trent Road. However, none of the estimated concentrations exceeded the MACS or the non-residential GWSLs for Vapor Intrusion samples. A summary of ground water analytical results is presented in Table 2. A Well Location Map is included as Figure 4. A copy of the laboratory report is included in Appendix D. 5.0 CONCLUSIONS AND RECOMMENDATIONS • The Site is 31.62 acres located at the southwest intersection of South Glenburnie Road and ML King Jr. Boulevard.
