The landfill encompasses a total area of approximately 8.2 acres that is divided into three main areas: The North Flag, comprising an area that is approximately 250 feet wide and 650 feet long. The Strip Landfill, comprising an area that is approximately 150 feet wide and 1,900 feet long. The South Flag, comprising an area that is approximately 260 feet wide and 370 feet long. Waste was deposited at the site from 1955 to 1963 in trenches at depths of 6 feet to 25 feet below ground surface (bgs), with total waste deposited estimated at 150,000 cubic yards. Material in the landfill consists of sanitary waste, construction debris, rubble, medical waste, and empty petroleum containers (IT Corp. 1994). The engineered cap consists of a 30-millimeter (mil) high density polyethylene (HDPE) liner with bentonite backing overlain by 9 inches of screened native soil and 9 inches of a vegetative layer (IT Corp. 1995a). The site is suspected of being one of the potential sources of tetrachloroethene (PCE) and trichloroethene (TCE) contamination in the groundwater (Tetra Tech 1998). Groundwater has begun to infiltrate the waste on the northern end of the landfill due to rising groundwater levels. CCR Title 27, Chapter 3, Subchapter 2, Article 3(c), Section (§) 20240, states that landfill waste must be at least 5 feet above the surface of the groundwater in order to prevent potential contamination of the groundwater. The Air Force evaluated corrective actions and costs of remediation in order to bring LF004 landfill back into compliance with CCR Title 27, Chapter 3, Subchapter 2, Article 3(c), § 20240 (AECOM 2009). Additional groundwater sampling was performed by Montgomery Watson Harza, Inc. (MWH) from 2007 through 2008, which determined that the submerged waste in the north end of the LF004 landfill was not a continuing source of contamination (AFRC 2009a; MWH 2009). During the April 2009 Remedial Project Managers' Meeting, the Regional Water Quality Control Board (RWQCB) agreed that the existing remedy was adequate and that further action at the site would not be necessary (AFRC 2009b). A discussion of the remedial options and the final determination is available in the Revised Final Operable Unit 1, IRP Site 4, Landfill No. 6 Rising Groundwater Evaluation Report, which was published in December 2009 (AECOM 2009).

The landfill encompasses a total area of approximately 5 acres. The landfill has a non-engineered soil cover that is approximately 4 feet thick. Waste was deposited at the site from the late 1940s to approximately 1960 in trenches at depths of 4 feet to 21 feet bgs, with total waste deposited estimated at 18,500 cubic yards. Material in the landfill consists of glass, scrap metal, wood construction debris, and newspapers as described in the OU1 remedial investigation/feasibility study (RI/FS) (The Earth Technology Corporation 1994). The site was extensively investigated during the OU1 RI/FS. Soil samples from boreholes, test pits, and surface locations as well as soil gas and groundwater samples were collected and analyzed. Based on the analytical results no significant levels of contamination were found in the soil or soil gas. A portion of the OU1 groundwater volatile organic compound (VOC) plume is situated beneath the site. The site is not a suspected source area for the plume. Based on the results of OU1 RI/FS LF005 was designated a no further action (NFA) site in the OU1 ROD (USAF 1995). No ICs or land use controls (LUCs) were identified as part of the remedy for Site 5; however, since landfill materials remain in place the LUC objective is to maintain a record of the landfill (see Section 3.2.2). 1.2.3 IRP SrrE 6, LANDFILL No. 4 IRP Site 6, Landfill No. 4 (LF006) is in the western area of the former March AFB, just south of Van Buren Boulevard (Blvd) (Figure 1-2). The landfill was closed in 1997 (IT Corp. 1997) in accordance with Title 23 of the CCR. The remedy as described in the OU2 ROD (USAF 2004) was ICs, and included long-term OM&M provisions. See Section 3.3.6 for further information on LF006 ICs. The site was previously a group of quarry pits that were backfilled with various wastes such as petroleum contaminated soil, construction debris, lime ash, munitions debris, and domestic debris. Disposal of wastes at LF006 ended in the early 1980s. The site encompasses approximately 15 acres. Two separate, lined waste cells (Cells A and B) were constructed as a part of site closure (IT Corp 1995b). The landfill contains a leachate collection and removal system (LCRS) that was WP,March AFB Moller AkBA21113 \ Sites 4,5,&612012 Amami RA-OTC-07021313A Afoot 1-3 July 2013 110.1 L 11 L 1\ Tr Z..

The program is designed to preserve (and restore, if necessary) the function of the landfill caps and drain systems and to monitor groundwater quality. In 2003, the program began to monitor vadose zone gas migration originating from the closed landfills LF004 and LF006. No ICs or LUCs were identified as part of the NFA remedy described in the OU1 ROD for LF005; however, since landfill materials remain in place, the LUC objective and semiannual inspection is to maintain a record of the landfill. Routine inspection, maintenance, and monitoring activities are to be performed and documented for a 40-year and 43-year post -closure period at LF004 and LF006, respectively. These requirements are documented in the Closure and Post-Closure Maintenance Plan for Sites 4 and 6 (IT Corp. 1994, 1995b, and 1995c) and other documents that detail post-closure OM&M of the sites including As-Built Documentation and Closure Certification Reports (IT Corp. 1995a and 1997), operations and maintenance work plans (Black & Veatch 1999a and 1999b, and AECOM, 2010), landfill gas sampling work plans (Black & Veatch 2002, 2003a, and 2003b; Earth Tech 2004; and AECOM, 2010), and groundwater sampling plans (Tetra Tech 1998 and AECOM 2010). The selected remedies for LF004 and LF006 as established in the OU I and OU2 RODs, respectively, are cap maintenance and system monitoring (USAF1995 and 2004). In order to insure that the remedies are maintained, ICs that run with the land are included in the property transfer deed as land use restrictions (March Joint Powers Authority 2006, and Moreno Valley Community Service District 2008). As part of landfill OM&M, the Air Force conducts an annual inspection to confirm that the ICs that are part of the remedy have not been violated. IC Monitoring Checklists are located in the Landfill OM&M Work Plan Addendum (AECOM 2010) for LF004 and LF006; and located in Land Use Control Implementation Plan, Sites 1, 5, 11, 18, 29, 31, and 33 (AECOM 2012a) for LF005. LFG monitoring probes monitor vadose zone gas migration at LF004 and LF006. Probes are monitored to determine if methane concentrations at the perimeter of the landfills remain below the 5 percent regulatory threshold established in CCR Title 27.

Groundwater sampling at LF004 and LF005 is being conducted and reported under the March ARB Long-Term Groundwater Monitoring Programs and is not included in this annual report. The groundwater wells at LF004 and LF005 are monitored semiannually and information will be available in the 2011-2012 and the 2012-2013 Annual Monitoring Reports prepared for AFCEC Groundwater Monitoring Programs, March ARB, California (AECOM, 2013a and 2013b). Presented below is an outline of proposed basic requirements of the inspection, maintenance, and monitoring activities, and the timeline for those activities from the Landfill RA-0 Work Plan Addendum (AECOM 2013c). Semiannual Activities: Formal inspections of the landfill cap, vegetative surface, subdrain system, drainage ditches, channels, LCRS, groundwater extraction and monitoring wells, LFG probes, settlement monuments, site security, and roads as applicable at LF004, LF005, LF006. Locations are presented on Figure 2-1, Figure 2-2, and Figure 2-3, respectively. Conduct maintenance if necessary at LF004, LF005, and LF006 identified during inspections. Monitor LFG perimeter probes at LF004 and LF006 for LFGs (measured as methane) using field instruments. Monitor and sample LF006 leachate collection system leachate levels at the two LCRS risers (LCRS-1 and LCRS-2). Monitor and sample LF006 subdrain groundwater from manhole (MH)-2. Remove leachate at LF006 as identified during monitoring to prevent leachate levels from making contact with the waste mass. Monitor and sample LF006 groundwater from two upgradient background monitoring wells (5M6MW5, 6M6MW3) and three downgradient point of compliance (POC) monitoring wells (6M6MW5, 6M6MW6, and 6M6MW7). Produce a semiannual report (first and second quarters) documenting the RA-0 activities performed at LF004, LF005, and LF006.

Produce a report documenting the RA-0 activities performed at LF004, LF005, and LF006 during the calendar year. After Major Rain Events: Inspect the same parameters as during semiannual activities to ensure proper operation after major rain events. Inspect landfill caps for excessive/significant ponding due to settlement. Every 5 Years: Survey settlement monuments at LF004 and LF006 to determine the extent the surface of the engineered cap membrane has settled due to degradation of the underlying collected waste. The last settlement monument surveys were conducted in April 2008 and the next settlement monument surveys will take place in 2013. %V RN larch AFB rfornuT A RB1120I1Sitts 4,5.8612012 Maud 3BA.docx 2-3 July 2013 AECOM Final Annual 2012 LF004, LF005, and LF006 RA-0 Report March ARB and Former March AFB 3.0 LANDFILL REMEDIAL ACTION-OPERATION RESULTS LF004 and LF006 quarterly RA-0 inspections and LFG perimeter probe monitoring were conducted in March 2012, May 2012, September 2012, and December 2012 by AECOM. LF005 semiannual inspection was conducted in December 2012. Sampling of LF006 groundwater compliance monitoring wells took place in May 2012 and December 2012. Completed inspection and maintenance forms, photographic documentation of inspections and maintenance performed, laboratory analytical results, leachate non-hazardous waste manifests, and statistical analysis results are included in Appendices A, B, C, D, and E, respectively. 3.1 LF004 REMEDIAL ACTION-OPERATION ACTIVITIES 3.1.1 LANDFILL OPERATIONS AND MAINTENANCE AECOM personnel conducted quarterly inspections of LF004 in March 2012, May 2012, September 2012, and December 2012. See Appendices A and B for completed inspection and maintenance forms and photographic documentation of inspections and maintenance performed. The following summarizes the significant findings and observations from the inspections and the maintenance activities. Final Cover and Parking Area: The landfill cap and parking area were found to be generally in good condition throughout the year. Subdrain System, Drainage Ditches, and Channels: A small amount of mud, brush, and litter was noted in the 8th Street rain gutter and daylight channel at the south end of the strip landfill during the September and December 2012 inspections. Cleanup of debris was conducted in October 2012 and January 2013 to prevent blockage of stormwater runoff. The south flag daylight drainage was found to be filled with dirt in September 2012. Maintenance and repair occurred in October 2012; ditch was dug from the daylight to the channel that drains to the south drainage ditch. The subdrain cleanout risers were inspected and found to be intact. Stormwater in the drainage ditch immediately to the north of LF004occasionally overflows into the overflow channel to the west of the north flag, flowing south along the 8th Street gutter. The overflow channel was designed to produce a sheet flow across the expanse of the channel; however, a smaller preferential flow channel has developed over time along the western edge of the overflow channel. A review of historic aerial photographs shows that the smaller channel was likely developed from a low spot created by a dirt road that was established in the overflow channel a few years after the w Mai,11 ionner A R131,..20iY,Sitem 4.5.&612012 Annual RA.01R2.070Z1313A.dOCI July 2013 AECOM Final Annual 2012 LF004, LF005, and LF006 RA-0 Report March ARB and Former March AFB landfill was closed. There is no evidence that the smaller channel is affecting the integrity of the landfill. This area will continue to be monitored. Vegetative Cover: The vegetative cover was found to be generally in satisfactory condition and previous bare areas on the cap due to drought and light vehicular traffic during routine RA-0 activities now have growth. Security Controls: Fences, gates, dummy security cameras, motion sensor lights, and signs were in satisfactory condition. Settlement Monuments: Settlement monuments remain in satisfactory condition. Groundwater Extraction and Monitoring Wells: All of the wells appear to be in satisfactory condition and no deficiencies were noted. Overgrown brush was cleared from around the extraction and monitoring wells as needed. LFG Perimeter Probe: The probes, the concrete skirts, and covers were intact and in good condition except for the concrete skirt around perimeter probes LFG-8a and LFG-8b. During a rain event in August 2012 soil was washed away exposing the casing around perimeter probes LFG-8a and LFG-8b. Soil was added around and under the concrete skirt around LFG probes LFG-8a and LFG-8b in September 2012. Overgrown brush was cleared from around the monitoring probes as needed. No other deficiencies were identified. 3.1.2 LANDFILL GAS PERIMETER PROBE MONITORING LFG monitoring samples were collected directly from the perimeter probes around the perimeter of the landfill (LFG-6a, LFG-6b, LFG-7, LFG-8a, LFG-8b, LFG-9, and LFG-10), using a CES-LANDTEC GEM-2000, a field instrument used for measuring LFG composition. Table 3-1 summarizes the results from the 2012 quarterly sampling events at LF004. During 2012, methane concentrations measured in the perimeter probes were well below the 5 percent regulatory threshold limit at 0.0 percent by volume during the quarterly sampling events. LFG6a was submerged during the second quarter and a reading could not be obtained. LFG-6a and LFG-10 were submerged in water during the fourth quarter and readings could not be obtained. Methane concentrations measured in the perimeter probes since 2002 have been below the 5 percent regulatory threshold limit, except LFG-9 (See Appendix F-1). Methane concentrations measured in LFG-9 have exceeded the regulatory threshold limit in March 2003, March 2005, March 2010, and March 2011 at 14 percent by volume, 7 percent by volume, 32 percent by volume, and 34 percent by volume, respectively. Based on a review of historical rainfall data the elevated methane readings in LFG-9 follow major rain events which cause stormwater from the WP1Masvh AFB Mourner ARBA2:03 \Sim 4,5.&612012 Amiga!

The methane levels in the perimeter probes at LF004 will continue to be tracked. 3.1.3 POST-DISASTER SYSTEMS INSPECTION A visual inspection of the landfill systems is to be conducted after a major meteorological or other major natural event. A major meteorological event is defined as 2 or more inches of rainfall over a 24-hour period. The September 2012 quarterly inspection was also considered a post major meteorological event inspection. There was more than 2 inches of rainfall on 30 August 2012. The final cover, subdrain system, drainage channels, monitoring wells, fences and gates, LFG probes, and settlement monuments were inspected in September 2012. Based on the September inspection the integrity of the landfill did not appear to be impacted by the rainfall event. See previous sections for further information on inspection results. 3.1.4 RESTRICTIONS/INSTITUTIONAL CONTROLS The IC inspection was performed by AECOM on 26 September 2012, and the inspection results are shown in Table 3-2. No violations of any of the ICs were noted during the inspection. 3.2 LF005 REMEDIAL ACTION-OPERATION ACTIVITIES 3.2.1 LANDFILL OPERATIONS AND MAINTENANCE AECOM personnel conducted a semiannual inspection of LF005 in December 2012. See Appendices A and B for completed inspection and maintenance forms and photographic documentation of inspections and maintenance performed. The following summarizes the significant findings and observations from the inspections and maintenance activities. Non- Engineered Cover: The cover was generally in good condition and intact. Settlement was noted in areas associated with the former landfill trenches. The vegetation present at LF005 is currently mowed by the Base ground maintenance subcontractor. Small animal burrows were also noted. The non-engineered cover will continue to be monitored and repairs will be done if waste is exposed.

See Appendices A and B for completed inspection and maintenance forms and photographic documentation of inspections and maintenance performed. The following summarizes the significant findings and observations from the inspections and the maintenance activities. Cover Surface: The landfill cap and cover surface were found to be generally in good condition. Small amounts of litter were noted and picked up. Minor animal burrowing was also noted. Animal burrows generally targeted for repair activities during the operations and maintenance process includes those that pose a threat to the integrity of the landfill cap. Examples of animal burrows subject to the digging and refilling process include burrow complexes created by the California ground squirrel and pocket gopher. Drainage and Subdrain System: The subdrain and perimeter drain cleanout risers were found to be intact and generally in good condition. Vegetation was cleared around cleanout risers. Vegetation was noted and removed from the perimeter drain daylight and the Van Buren Boulevard subdrain outfall. Manhole (MH)-2 was in good condition and shows a clear and steady flow of subdrain groundwater. The locations of the cleanouts, MH-2, perimeter drain, and Van Buren Boulevard subdrain outfall are shown on Figure 2-3. The surface drainage is also shown on Figure 2-3. Vegetative Cover: The vegetative cover was generally in good condition. Small animal burrows were noted and some litter was noted as well. Litter was removed and animal burrows were filled in as necessary. Animal activity will continue to be monitored and repairs will be done before the integrity of the cap is compromised. No additional maintenance activities were performed or required on the vegetative cover. Security Controls: Fences, gates, and signs were in good condition. Settlement Monuments: Settlement monuments remain in good condition. Groundwater Monitoring Wells: All of the wells appear to be in satisfactory condition and no deficiencies were noted. Brush was cleared from around monitoring wells.

The riser distance to leachate was measured at LCRS-1 and LCRS-2 and the water level was measured at MH-2. Measurements are presented in Table 3-4. compared with rainfall accumulation. Table 3-5 presents LCRS-2 average recharge rates Based on the comparison leachate recharge rates were significantly higher during months following elevated rainfall accumulation at LF006. The increase in leachate production during the rainy season is indicative of rainwater infiltration through imperfections (e.g., small tears, rodent burrows, gas vents, poor finer seam welds) in the top liner of Cell B. Leachate will continue to be pumped out of LRCS-2 on an ongoing basis to keep leachate from coming in contact with landfill waste. Leachate depths above 18 inches require sampling, analysis, removal by pumping out, and appropriate disposal. An evaluation of the as-built engineering drawings of the leachate sumps establishes distances from the sump riser entrance to the leachate of 60.5 feet or less for LCRS-1 and 137.5 feet or less for LCRS-2 as the trigger levels. During 2012, Ieachate was pumped from LCRS-2 in two separate events. Leachate was pumped in March and June 2012. Approximately 15,000 gallons of leachate was drawn out of LCRS-2 during 2012. Approximately 1,000 gallons of leachate was pumped from LCRS-1 in 2012 (see Appendix D for waste manifests). Additional removal of leachate is scheduled to occur the second quarter of 2013. Leachate samples from LCRS-1 and LCRS-2and a subdrain water sample from MH-2 were collected during the second quarter and fourth quarter of 2012. Each sample was analyzed for VOCs and general minerals, i.e., total dissolved solids (TDS), chloride, nitrate, sulfate, and alkalinity. Analytical results are presented in Table 3-6 and laboratory results are included in Appendix C. Analytical results of leachate samples were compared to the analytical results of subdrain water samples. Based upon these comparisons no releases have occurred from the landfill. WI".

The 2012 groundwater elevation readings are presented in Table 3-7 and summarized in Figures 3-1 through 3-4. The groundwater surface maps for LF006, developed from quarterly depth to groundwater readings, indicate northeasterly direction of groundwater flow during 2012. Groundwater elevation at LF006 has stayed fairly constant over the last five years. See Figure 3-5 for a summary of groundwater elevation levels. AECOM personnel conducted semiannual groundwater sampling during the second quarter and fourth quarter of 2012. Sampling events followed the sampling protocol outlined in the Landfill OM&M Work Plan Addendum (AECOM, 2010) and recommended in the 2011 Sites 4 and 6 Annual OM &M Report (AECOM, 2012b). A no purge HydraSleeveTM sampling technique was used to sample groundwater at LF006 during the semiannual groundwater sampling event. Groundwater samples were analyzed for VOCs and general minerals, i.e., TDS, chloride, nitrate, sulfate, and alkalinity. A summary of the 2012 groundwater sampling results are presented in Table 3-8, and the 2012 laboratory results are included in Appendix C. 3.3.3.1 Upgradient and Doi% ngradient Statistical Comparison. Statistical comparisons between COC concentrations in the two upgradient background wells and the three downgradient monitoring wells were made in accordance with the United States Environmental Protection Agency (USEPA) guidance document, Statistical Analysis of Groundwater Data at Resource Conservation and Recovery Act Facilities (USEPA 1989). This comparison was done using several techniques from the guidance document; calculation of the 95 percent upper tolerance levels (UTLs), Analysis of Variance Analysis (commonly known as ANOVA), and the Bonferroni T-statistic Test. The statistical tests are described in detail in Appendix F of the Final 2003-2004 Annual Monitoring Report, AFRC and AFRPA Groundwater Monitoring Programs, March AFB, California (MWH 2005). The 95 percent UTLs for 2012 were calculated using current and historical data collected from background Wells 5M6MW5 and 6M6MW3, located upgradient from the landfill. A spreadsheet of 95 percent UTL calculations for background wells is included in Appendix E-1. Data collected from three downgradient monitoring Wells 6M6MW5, 6M6MW6, and 6M6MW7 were then compared to the WPMalch A FB I former ARB)1201Miles 4,5,W/12012 Animal RA, 01F12-070213BA .doce 3-6 July 2013 AECOM Final Annual 2012 LF004, LF005, and LF006 RA-0 Report March ARB and Farmer March AFB calculated 95 percent UTL. Table 3-9 summarizes the historical general mineral and VOC data of the five sampled monitoring wells and the corresponding 95 percent UTL from the two upgradient background wells. The results of these analyses demonstrate that concentrations of chloride, nitrate, TDS, and PCE detected downgradient of the landfill and in the landfill subdrain water are below the 95 percent UTL of chloride, nitrate, TDS, and PCE calculated from upgradient of the landfill. Sulfate concentrations in downgradient Wells 6M6MW5 and 6M6MW6 were greater than the 95 percent UTL of sulfate calculated from upgradient of the landfill. The sulfate concentrations detected in monitoring Wells 6M6MW5 and 6M6MW6 have historically been above the calculated 95 percent UTL. The data sets shown in Table 3-9 were statistically tested to determine if there was a significant difference between analyte concentrations in the background wells and downgradient wells. Also included in this test was the subdrain data set (MH-2 samples) to determine if there was a significant difference between analyte concentrations in the background wells and the landfill subdrain water. Summary spread sheets of the statistical analysis are included in Appendix E. The results of these analyses demonstrate that the mean concentrations of chloride, nitrate, and PCE detected downgradient of the landfill and in the landfill subdrain water are not statistically different from the corresponding mean concentrations of chloride, nitrate, and PCE detected upgradient of the landfill. This analysis performed for sulfate in downgradient wells demonstrates that the mean concentration of sulfate in downgradient Wells 6M6MW5 and 6M6MW6 is statistically greater than the mean concentration of sulfate detected upgradient of the landfill. The sulfate concentrations detected in monitoring Wells 6M6MW5 and 6M6MW6 have historically been above the calculated 95 percent UTL. The results of these analyses demonstrate that the mean concentration of sulfate detected in the landfill subdrain water is statistically equal to the corresponding mean concentration of sulfate detected upgradient of the landfill. The mean TDS concentration in downgradient Well 6M6MW5 is statistically greater than the mean concentration of TDS detected upgradient of the landfill; however, the mean concentration is less than the mean concentration of one of the upgradient wells. 3.3.4 LANDFILL GAS PERIMETER PROBE MONITORING LFG monitoring samples were collected directly from the perimeter probes around the perimeter of the landfill. LFG perimeter probe locations are identified on Figure 2-3. LFG samples were collected WF,Mant AFB Iformer ARB),..2013'Soles 4.5.646',2012 Annual RA -01P2-070213BA dexx 3-7 July 2013 AECOM Final Annual 2012 LF004, LF005, and LF006 RA-0 Report March ARB and Former March AFB directly from the probes using a CES-LANDTEC GEM-2000. Table 3-10 summarizes the results from the 2012 quarterly sampling events at LF006 and includes all of the currently sampled monitoring probes. The methane concentrations measured in all of the LFG probes during the 2012 sampling events were between 0.0 and 0.1 percent by volume; well below the regulatory threshold limit of 5 percent by volume. Therefore LF006 is considered compliant with CCR Title 27 since all perimeter probes show methane concentrations below the 5 percent methane limit. Methane concentrations have not been above the regulatory threshold limit since perimeter probe monitoring began at the new probe locations at LF006 in 2004 (see Appendix F-2). 3.3.5 POST-DISASTER SYSTEMS INSPECTION A visual inspection of the landfill systems is to be conducted after a major meteorological or other major natural event. A major meteorological event is defined as 2 or more inches of rainfall over a 24-hour period. The September 2012 quarterly inspection was also considered a post major meteorological event inspection. There was more than 2 inches of rainfall on 30 August 2012. The final cover, subdrain system, drainage channels, monitoring wells, fences and gates, LFG probes, and settlement monuments were inspected in September 2012. Based on the September inspection the integrity of the landfill did not appear to be impacted by the rainfall event. See previous sections for further information on inspection results. 3.3.6 RESTRICTIONS/INSTITUTIONAL CONTROLS The IC inspection conducted by AECOM on 25 September 2012, and the inspection results are shown on Table 3-11. No violations of any of the ICs were noted during the inspection. WR,Alards . AFB (hvrrner A FtS)',2013Sites 4,5,802012 Animal RA-OT12.010213BA.ducx 3-8 July 2013 AECOM Final Annual 2012 LF004, LF005, and LF006 RA-0 Report March ARB and Former March AFB 4.0 CONCLUSIONS AND RECOMMENDATIONS This program is designed to preserve (and restore, if necessary) the function of the landfill caps and drainage systems, and to monitor groundwater quality and vadose zone gas migration originating from the closed landfills. During 2012, quarterly monitoring and inspections indicated minor maintenance and repair needs at LF004; the majority resulted from rain events. Rain events have caused minor erosion and deposition of drainage channels, fence lines, and around monitoring points. These were investigated to ensure the integrity of the landfill caps and drainage systems remain intact. No evidence of damage to the landfill cap or drainage system was found and repairs and maintenance due to erosion and deposition were performed. During 2012, quarterly monitoring and inspections indicated minor maintenance needs at LF006; the majority resulted from vegetation growth. The Site 6 Post Closure Maintenance Plan (IT Corp. 1995b) indicates that leachate generation from the waste is expected to be very low. The quantity of leachate removed from LCRS-2 in the last two years does not reflect this. In 2012, approximately 15,000 gallons of leachate were drawn from LCRS-2. Approximately 1,000 gallons were drawn out of LCRS-1 due to leachate levels above trigger levels in 2012. The frequency of measuring leachate levels in LCRS-2 was increased to evaluate the rate of leachate recharge in the sump. The relatively small quantity of leachate pumped from LCRS-1 has maintained the leachate level below the action level (60.5 feet), but the far greater quantity pumped from LCRS-2 has not kept the leachate level from exceeding the action level (137.5 feet) several times. Despite quantities up to 7,500 gallons of leachate being removed at a time, leachate levels persistently return to the trigger level in a few months. Leachate recharge rates were significantly higher during months following elevated rainfall accumulation at LFOO6 (see Table 3-5). The increase in leachate production during the rainy season is indicative of rainwater infiltration through imperfections (e.g., small tears, rodent burrows, gas vents, poor liner seam welds) in the top liner of Cell B. Leachate will continue to be pumped out of LRCS-2 on an ongoing basis to keep leachate from coming in contact with landfill waste.

One field duplicate was collected this sampling round. The agreement between the samples and the duplicates was excellent. Raw data of all analytical methods for sample 3506127-03 was reviewed at level D. Qualifiers were assigned to the sample data as listed below. 3506127 8260B: the % recovery for t-butanol was below the acceptance criteria in the continuing calibration verification standard and was non-detect (ND) in all samples. A al qualifier was assigned to the t-butanol results for all samples except sample -09 (see sample -09 matrix spike/matrix spike duplicate below). 8260B, sample -09 MS/MSD: the % recovery for sec-butylbenzene was above the acceptance criteria in sample -09 MS/MSD: the % recoveries for tert-Butylbenzene, isopropylbenzene, npropylbenzene and o-xylene were above the acceptance criteria in sample -09 MS; the relative percent difference was above the acceptance criteria for t-butanol in sample -09 MS/MSD. An M qualifier was assigned to the sec-butyIbenzene, tert- butylbenzene, isopropylbenzene, npropylbenzene, o-xylene and t-butanol results (all ND) in sample -09. 300.1: Nitrate was originally analyzed within holding time for all samples and reanalyzed for samples -03 through -07 and -12 due to required dilutions three days past holding time. A "J" qualifier was assigned to the nitrate results for samples -03 through -07 and -12, 300.1, sample -09 MS/MSD: the % recovery for nitrate was below the acceptance criteria in sample -09 MS/MSD. An M qualifier was assigned to the nitrate result in sample -09. cc: Matthew Hansen Jennifer Hendricks Bob Simpson Nancy Carpenter MARB Site 6 Landfill memo 062712 ""' gm gig im gm 1111 115 7 mg/Ph Arl al Afft 1111/0of FINAL DATA - PRINTED 06126/2912 (Page 1 of 8) Rase Site Point Sampling Date Sample Depth Sample Type Field Sample Lab Sample PVC / Run Status Analyte MARCH NA 5M6MW05 05/1712012 11:50 MARCH NA 6M6MW03 05/1712012 09:20 N1 N1 IRP6-5M6MW05-WG023 3506127-07 IRP6-6M6MW03-WG022 3506127-08 PR / 1 PR / 1 Validated Validated PH Method E150.1 Result Units pH units 7.16 total dissolved solids E160.1 mg /L 628 chloride nitrate (as N) nitrite (as N) suffate E300.1 E300.1 E300.1 E300.1 mg/L 77.0 29,3 alkalinity, bicarb.

Two field duplicates were collected this sampling round. The agreement between the samples and the duplicates was excellent. Nitrite was detected at 1.1 mg/L for sample -04 and non-detect (ND) in the 5x dilution for sample -05. TAMS stated nitrite was not analyzed without dilution for sample -05 due to the levels of chloride and sulfate present in the sample; although nitrite was analyzed without dilution for sample -04 which contained the same levels of chloride and sulfate. Qualifiers were assigned to the sample data as listed below. 6010B Trace, below the reporting limit, lead was detected in the laboratory method blank (LMB) and sample -08. A "13" qualifier was assigned to lead in sample -08. 8260B Trace methylene chloride, naphthalene, 1.2,3-trichlorobenzene and , and 1,2,4-triehlorobenzene was detected in the LMB. 1,2,4-trichlorobenzene was ND in the associated field samples. Trace methylene chloride was found in the trip blank (TB) as well as all the associated field samples. Trace naphthalene and 1,2,3-trichlorobenzene were found in sample -04. A "B" qualifier was assigned to methylene chloride in the TB and all samples; and to naphthalene and1,2,3trichlorobenzene in sample -04. 9012B Trace cyanide was in the LMB and samples -01, -02, -03, -06 and -07. Cyanide in samples -01 through -03 were greater than 5 times the value in the LMB, no qualifier was required. A "B" qualifier was assigned to cyanide in samples -06 and -07. MARE Siie 6 Landfill memo 0218 2013 March AR # 2757 Page 131 of 201 Cyanide % recoveries were below the acceptance limit in sample -03 matrix spike and matrix spike duplicate (MS/MSD). An "M" qualifier was assigned to cyanide in sample -03 due to matrix effect. cc: Matthew Hansen Jennifer Hendricks Nancy Carpenter MARB Sitc 6 Landfill memo 0218 2013 'm mi im 6117 5 711. h # In 1. 111, o f 11.1 FINAL DATA - PRINTED 02/1912013 (Page 1 of 7) Base Site Point Sampling Date Sample Depth Sample Type Field Sample Lab Sample PVC i Run Status 36 - 39 MARCH Site 6 6M6MW05 12/19/2012 13:55 27.25 - 33.25 MARCH Site 6 6M6MWO6 12/19/2012 14:35 29 - 35 MARCH Site 6 6M6MW06 12/19/2012 14:35 29 - 35 N1 N1 N1 N1 FD1 IRP6-5MBMVV05-WG024 320-1336-01 PR / 1 Validated IRP6-6M6MW03-W6023 320-1336-02 IRP6-6M6MW05-1NG025 320-1336-03 IRP6-6M6MW06-WG024 320-1336-04 IRP6-6M6MW06-WG025 320-1336-05 PR / 1 Validated PR / 1 PR / Validated PR / 1 MARCH Site 6 5M6MW05 12119/2012 15:25 52 - 55 MARCH Site 6 6M6MWO3 Re-sult alkalinity, hydlox.
