This document has been prepared based on historical site assessment data and has been prepared to address soil and groundwater contamination at the Pierce's Grocery site (Facility Identification Number 10437-035-011443) in Lenox, Conecuh County, Alabama. The recommended action should not be construed to apply to any other site. �yAJLAAN t~ m 7 d ig ature �fc� Date eme Alan Barck <DpRpp�9S1�� Registered Professional Geologist in the State of Alabama Registration No. 1074 PROJECT SUMMARY Pierce's Grocery once served as a general store and gasoline station in Lenox, Alabama. CDG Engineers &Associates, Inc. (CDG) initiated assessment activities at the Former Pierce's Grocery facility in 2001. Currently the site has fourteen Type II monitoring wells, one Type III vertical delineation well, seven C recovery wells, and seven 1" air sparge wells. Assessment and remediation activities have included conducting numerous groundwater monitoring events, the preparation of an Alabama Risk Based Corrective Action (ARBCA)Tier I/Tier II evaluation,and the preparation of a corrective action plan(CAP)formulti-phase extraction(MPE). Bass Oil Companyis the Alabama Tank Trust Fund (ATTF) responsible party for the Pierce's Grocery site. Beginning in 2009, it became increasingly evident that the corrective action system was not performingat an optimal level. Significant amounts of iron deposits accumulated in theflow lines from the recovery wells to the system so CDG replaced the lines to all of the recovery wells in January2012. Since that time, iron deposits have built up inside the flow lines once again despite the preventative measures employed by CDG. During the line replacement in 2012,the flow lines from five of the recovery wells (RW-1 through RW-5) were cased with conduit so that the inner tubing could be easily replaced at a later date if necessary.The MPE system was shut down in April 2015. In July 2016,ADEM requested that a modified CAP be submitted. On March 15,2017, CDG submitted a Modified CAP for the installation of an additional monitoring well, an additional recovery well,seven air sparge wells,and an air sparge(AS)system. The Liquid Ring Pump(LRP)for the system was replaced on December 11, 2018. The system was manually shut down and the system was winterized on September 30, 2019.The system was restarted on November 3, 2020. CDG Engineers&Associates, Inc.(CDG)is currently performing operation and maintenance(O&M) activities on the MPE treatment system. This report includes the O&M activities conducted during the period between April 1, 2021 and June 30, 2021 as approved in CP-88. The data summary tables are included in Appendix A and site figures, representing current groundwater conditions, are included in Appendix B. SUMMARY OF SITE ACTIVITIES During the operational period (April 2021—June 2021), CDG visited biweekly to perform various operation and maintenance, sampling, and system monitoring activities. 1 Groundwater Monitoring Activities Personnel from CDG mobilized to the site on June 28,2021 to collect groundwater samples forthe Chemicals of Concern (COC), which include benzene, toluene, ethylbenzene, and total xylenes (BTEX), methyl-tertiary-butyl-ether(MTBE), and naphthalene analysis. Upon arriving at the site, the technician removed the well caps from the twenty-one monitoring and recovery wells and the water levels in the wells were allowed to stabilize. Potentiometric levels were then measured with an electronic water level indicator or oil/water interface probe and recorded in the site field book. Based on the results from the most recent groundwater monitoring event,the groundwater flow direction beneath the site is to the southeast. After all measurements were completed,each of the twenty-one monitoring wells sampled was properly purged in preparation for groundwater sampling activities. Approximately 85 gallons of purge water were removed from the wells and treated using the on-site MPE system. Groundwater samples were collected from twenty-one monitoring and recovery wells for BTEX/MTBE/Naphthalene analyses using new, disposable bailers and transferred to 40 mL glass VOA vials preserved with HCL The samples were placed on ice and transported under chain of custody to Waypoint Analytical laboratory where they were analyzed by EPA Method 826013 for the presence of BTEX/MTBE/Naphthalene constituents. The analytical laboratory report is included in Appendix C. A copy of the groundwater sampling log, including purge water disposal information, is included in Appendix D. Laboratory Analysis Results The BTEX/MTBE/Naphthalene analyses for this event indicate that benzene and naphthalene concentrations were present at the site at levels above the Groundwater Resource Protection (GRP) Site Specific Target Levels (SSTLs) in two (MW-4 and RW-3) of the twenty-one sampled monitoring wells. All COC concentrations were reported to be below the established SSTLs for Indoor Air Inhalation. The concentrations above the approved SSTLs are as follows: Chemical of Concern GRP SSTLs Indoor Inhalation SSTLs Concentration M W-4 Benzene 0.0047 mg/L 6.64 mg/L 0.005 mg/L Naphthalene 0.0188 mg/L 31 mg/L 0.020 mg/L RW-3 Benzene 0.005 mg/L 6.64 mg/L 0.061 mg/L 2 Chemical of Concern GRP SSTLs Indoor Inhalation SSTLs Concentration Naphthalene 0.02 mg/L 31 mg/L 0.132 mg/L The Corrective Action System Effectiveness Monitoring Report(CASEMR)forms,UST Release Fact Sheet,and USTSite Classification System Checklist are included in Appendix H. A list of personnel performing tasks at the site is included in Appendix I. System O&M On April 22, May 27, and June 17, 2021, technicians traveled to the site to sample the system discharge. Water influent and effluent samples were collected and transferred to 40-ml-VOA vials, preserved with HCI, and analyzed for BTEX/MTBE/Naphthalene using Method 8260. In addition, water effluent samples were collected and analyzed for Oil and Grease (O&G) using EPA Method 1664E as required under the General NPDES Permit Number ALG340525.Effluent air samples were also monitored with a PID. In addition,pH,run time hours,gallons of water discharged,air stripper pressure, system vacuum, oil level, and temperatures were measured and recorded. Vacuum readings were taken at the wellheads for each of the recovery wells. CDG was contacted by the property owner regarding the water usage for the site. The current water service for the business is also the water service for the system. COG contacted Hamden Ridge Water and had a separate water meter installed for the system in March 2021. A water line from the meter to the system has not yet been installed due to property access concerns expressed by the current property owner. COG is currently paying the water service for the system and the store until an agreement can be made with the property owner. AIR QUALITY Off gases were monitored and results from the system air effluent analysis reported PID concentrations of 0 ppm,0 ppm,and 0 ppm for samples collected on April 22,May 27,and June 17, 2021, respectively. In a letter dated May 3,2018,the ADEM Air Division issued a letter stating that no state or federal emission standards were expected to be exceeded,so no permit was necessary for the Air Pollution Control Device (APCD). As stated by the Air Division, off-gas treatment is required until the benzene concentrations are consistently maintained at or below 1.770 Ibs/hr. An electric oxidizer 3 was being utilized at the site for off gas treatment until it was removed on August 9, 2017 and replaced with two 1,000-pound Granular Activated Carbon (GAC) vessels. A copy of the Air Division Approval letter and the Quarterly Air Division reports are included in Appendix E. REMEDIATION SYSTEM During the period (April 2021—June 2021), 62,182 gallons of groundwater were recovered and treated. The system has averaged,during this quarter,a calculated airflow rate of 325 actual cubic feet per minute(ACFM)and a groundwater extraction rate of 0.47 gallons per minute(gpm)with 1 day of down time as documented in the CASEMR forms located in Appendix H. A copy of the eDMRs, which are required as part of NPDES permit, are included in Appendix F. A list of the personnel performing tasks during the quarter is included in Appendix I. The following wells are currently being used for extraction: RW-1, RW-4, RW-6, and RW-7. The remaining recovery wells are currently inactive. FREE PRODUCT RECOVERY No free product was observed at the site during the quarterly period (April 2021—June 2021).Free product was last observed at the site in February 2012. CONCLUSIONS AND RECOMMENDATIONS Based on the data collected,the following conclusions can be made: • No free productwas observed in anyof the wells duringthis groundwater sampling event. Free product was last observed at the site in February 2012. • Two (MW-4 and RW-3) of the twenty-one sampled monitoring and recovery wells contained CDC concentrations above the GRP SSTLs. • All CDC concentrations were reported to be below the Indoor Air Inhalation SSTLs. • The MPE system appears to be effectively reducing petroleum contaminant levels in the soil and groundwater at the site. Since restarting the system, a significant decrease in CDC concentrations have been observed in comparison to when the system was shut down. 4 During this quarter, approximately 62,182 gallons of groundwater were recovered and treated. CDG will await ADEM's guidance before installing the water line from the newly installed water meter to the system.As discussed with ADEM,quarterly system cycling will begin with CP-89.The system was shut down on July 1, 2021 and will remain off until site activities for CP-89 are complete. 5 CDG Engineering.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters(NELAP and non-NELAP)were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule August 2017)and NELAC unless otherwise indicated. Any parameter for which the laboratory is not officially NELAP accredited is indicated by a'—'symbol. These are not included in the scope because NELAP accreditation is either not available or has not been applied for. Additional certifications may be held/are available for parameters,where NELAP accreditation is not required or applicable. A full list of certifications is available upon request. Certain parameters(chlorine, pH,dissolved oxygen, sulfite...)are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as- received basis unless otherwise indicated.This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information. Sincerely, -- n-� ' lAU1�JFY6 1'6jlilk� Consuelo C Bradley u Laboratory's liability in any claim relating to analyses performed shall be limited to,at laboratory's option,repeating the analysis in question at laboratory's expense, or the refund of the charges paid forperformance of said analysis.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters(NELAP and non-NELAP)were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule August 2017)and NELAC unless otherwise indicated. Any parameter for which the laboratory is not officially NELAP accredited is indicated by a'-'symbol. These are not included in the scope because NELAP accreditation is either not available or has not been applied for. Additional certifications may be held/are available for parameters,where NELAP accreditation is not required or applicable. A full list of certifications is available upon request. Certain parameters(chlorine, pH,dissolved oxygen, sulfite...)are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as- received basis unless otherwise indicated.This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information. Sincerely, -- n-� ' lAU1�JFY6 1'6jlilk� Consuelo C Bradley u Laboratory's liability in any claim relating to analyses performed shall be limited to,at laboratory's option,repeating the analysis in question at laboratory's expense, or the refund of the charges paid forperformance of said analysis.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters(NELAP and non-NELAP)were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule August 2017)and NELAC unless otherwise indicated. Any parameter for which the laboratory is not officially NELAP accredited is indicated by a'-'symbol. These are not included in the scope because NELAP accreditation is either not available or has not been applied for. Additional certifications may be held/are available for parameters,where NELAP accreditation is not required or applicable. A full list of certifications is available upon request. Certain parameters(chlorine, pH,dissolved oxygen, sulfite...)are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.

It has been determined that off-gas treatment will not be required at this time. Also, a review of the remediation system has led to the determination that no state or federal emission standard is expected to be exceeded and the remediation system will not require permitting at this time. The Air Division does not require sampling or reporting for sites without off-gas treatment. If any of the factors in the operation of the remediation system change,you should notify the Air Division g1k to those changes so that a reevaluation can be made.
