2.0 SITE BACKGROUND

2.1 Site Description
The subject property consists of three parcels of land comprising approximately 14.2 acres located on the north side of Airport Drive within a mixed commercial and industrial area of San Bernardino County, California. The subject property is currently occupied by the Scoular Company with a sub-lease on the property to Verhoeven Grain Company for commercial/industrial use. The subject property is a grainhandling facility that has been in operation since at least 1973 and is developed with six buildings. On-site operations consist of loading and unloading of multiple types of grain from the adjacent rail yard, storing, milling, and processing the grain for bulk and retail sale. In addition to the current structures, the subject property is also improved with bulk storage silos, milling facilities, and maintenance areas. The subject property has landscaping on the southern boundary, along Airport Drive.

The subject property is bound by commercial properties to the north across the railroad, commercial properties to the east, commercial properties to the south across East Airport Drive, and commercial properties to the west. Refer to Figure 1 for a site plan showing site features and surrounding properties.

2.2 Site History
Partner is concurrently conducting a Phase I Environmental Site Assessment Report (Phase I) on behalf of Prologis. Based on the information reviewed and the site reconnaissance, the subject property was previously undeveloped as early as 1932; developed as agricultural land between 1938 and circa 1970; and developed with the current structures in 1973. Tenants on the subject property have included Chino Grain Company (1985); Coast Grain Company (1990-2003); J.B. Heiskell & Co. (2008); The Scoular Company (2006- Present); and a sub-lease to Verhoeven Grain Company (2008-Present).

Based on the historical information review, at least one and up to as many as five petroleum USTs were situated on the subject property prior to 2012. Regulatory closure letters address the removal of the three former 12,000-gallon diesel USTs, but it appears that the “truck stop” UST removed in 1986 has no documented removal. Based on the lack of information regarding the disposition of the USTs at this facility, the former UST are considered a recognized environmental condition (REC).

The subject property is currently equipped with two 250-gallon aboveground storage tanks (ASTs) containing diesel fuel. The original installation date is unknown. Based on the lack of information regarding the age and installation dates of these ASTs at this facility, the ASTs are considered a REC.

During the site visit, it was noted that sanitary discharges from the subject property are directed to an onsite septic system. A maintenance area was observed on the property that included the use/storage of 20 to 30 55-gallon drums containing automotive fluids such as motor oil, waste motor oil, and antifreeze. Two 250-gallon diesel ASTs were present in this area. Diesel fuel is used to maintain the yard equipment, such as the front-end loaders, forklifts, and the bobcats. No floor drains were noted in the area of the diesel ASTs.

2.3 Geology and Hydrogeology
Based on a review of the United States Geological Survey (USGS) Guasti, California Quadrangle topographic map, the subject property is situated at an elevation approximately 975 feet above mean sea level, and the local topography is sloping gently to the south. Refer to Figure 2 for a topographic map of the site vicinity.

According to the California Geological Survey the subject property is situated in the Peninsular Ranges which are a series of ranges separated by northwest trending valleys, subparallel to faults branching from the San Andreas Fault. The trend of topography is similar to the Coast Ranges, but the geology is more like the Sierra Nevada, with granitic rock intruding the older metamorphic rocks. The Peninsular Ranges extend into lower California and are bound on the east by the Colorado Desert. The Los Angeles Basin and the island group (Santa Catalina, Santa Barbara, and the distinctly terraced San Clemente and San Nicolas islands), together with the surrounding continental shelf (cut by deep submarine fault troughs), are included in the province.

Based on borings advanced during this investigation, the underlying subsurface consists predominantly of brown, very fine grained, medium dense, damp, silty sand (SM) from the ground surface to approximately 20 feet below ground surface (bgs). From 20 to 25 feet bgs, the subsurface consists predominantly of brown, very fine to coarse grained, dense, damp, poorly graded, sand (SP). Refer to Appendix A for boring logs from this investigation.

Information specific to the subject property regarding the depth to groundwater and direction of groundwater flow was not available for the subject area. However, according to information obtained from online research, depth to the high water table is anticipated between 250 and 350 feet bgs. 2142

3.0 FIELD ACTIVITIES
Refer to Table 1 for a summary of the borings, sampling schedule and laboratory analyses for this investigation. The initial scope of the Phase II Subsurface Investigation included a geophysical survey and the advancement of 12 borings (B1 through B12) for the collection of representative soil and/or soil gas samples. Based on the results of the initial investigation, 13 additional soil gas borings (SV-13 through SV26) were advanced for the collection of representative soil gas samples.

3.1 Preparatory Activities
Prior to the initiation of fieldwork, Partner completed the following activities.

3.1.1 Utility Clearance
Partner delineated the work area with white spray paint and Underground Service Alert of Southern California (USA/SC) to clear public utility lines as required by law at least 48 hours prior to drilling activities.

USA/SC issued ticket number B61960144 for the project.

3.1.2 Health and Safety Plan
Partner reviewed the site-specific Health and Safety Plan with on-site personnel involved in the project prior to the commencement of drilling activities.

3.2 Geophysical Survey
On July 21, 2016, Ground Penetrating Radar Systems, Inc. (GPRS) conducted a geophysical survey under the supervision of Partner. The purpose of the geophysical survey was to identify USTs remaining in place, backfilled tankholds, septic tanks, and/or associated features, and clear boring locations of utilities. The geophysical survey was conducted with a Geonics EM-61 and a Fischer M-Scope electromagnetic induction (EM) equipment, a Schonstedt GA-52 magnetic gradiometer, a Sensors and Software Noggin ground penetrating radar (GPR) unit, and a Metrotech 9890 utility locator with line-tracing capabilities.

GPRS systematically free-traversed the investigation area with the aforementioned equipment. The equipment data were interpreted in real time and compiled as necessary in order to identify subsurface anomalies consistent with USTs, disturbed soil resembling backfilled tankholds, piping trenches, utility lines, and/or other subsurface conduits/features.

The geophysical survey identified one large anomaly in the eastern portion of the subject property to the west of Building B, under the canopy. The location and shape of the anomaly, which consisted of a backfilled excavation, generally corresponded to the location of the former USTs. No large metallic features were identified, which confirms that the USTs have been removed.

The geophysical survey also identified one large anomaly resembling a septic system to the north of Building A.

In addition, GPRS systematically free-traversed each proposed boring location with the aforementioned equipment and the equipment data were interpreted in real time for evidence of utility lines and/or other subsurface features of potential concern. Boring placement was modified as necessary based on the geophysical survey results to avoid damaging underground features. 2143

3.3 Drilling Equipment
On July 21, 2016, Partner subcontracted with Minute Man Drilling (MMD) to provide and operate drilling equipment. MMD, under the direction of Partner, advanced borings B1 through B12 with a truck-mounted Geoprobe Model 540MT direct push rig. Sampling equipment was decontaminated between sample intervals and boring locations to prevent cross-contamination.

After the initial laboratory results were received, further investigation was deemed necessary. On July 29, 2016, Partner subcontracted with Optimal Technology (Optimal) to provide and operate drilling equipment to install and sample 13 soil gas probes. Optimal, under the direction of Partner, advanced soil gas borings SV-13 through SV-26 with an electric rotary hammer drill. Sampling equipment was decontaminated between sample intervals and boring locations to prevent cross-contamination.

3.4 Boring Locations
Boring B1 was advanced to the east of the ASTs. Boring B2 was advanced to the west of the hazardous waste storage area in Building B. Borings B3 through B6 were advanced to the southwest, west, east, and north of the former UST tankhold, respectively. Borings B7 and B8 were advanced to the east and northwest of the septic system, north of Building A, respectively. Boring B9 was advanced in the north-central interior of the Building A maintenance area. Boring B10 was advanced to the east of the conveyor belt. Boring B11 was advanced in the west-central area of the vehicle wash down area. Boring B12 was advanced to the southeast area of the railroad spur.

Borings SV-13 and SV-14 were advanced to the southeast and northeast of the former USTs, respectively.

Borings SV-15 through SV-17 were advanced in the north-central, central, and southern interior of Building B, respectively. Boring SV-18 was advanced in the east-central area of the vehicle wash down area. Boring SV-19 was advanced to the southeast of the ASTs. Borings SV-20 and SV-21 were advanced to the northwest and west of the septic system, respectively. Boring SV-22 was advanced to the west exterior of Building A.

Borings SV-23 and SV-24 were advanced in the northeast and southeast interior of Building A, respectively.

Borings SV-25 and SV-26 were advanced in the northwest and southeast interior of the maintenance area of Building A.

Boring placement was limited/modified utility conflicts, and/or access by the drill rig. Refer to Figure 3 for a map indicating boring locations.

3.5 Boring Depths
Borings B1 through B11 and SV-13 through SV-26 were overlain by concrete, which was penetrated using a concrete coring attachment advanced by the direct-push drill rig and/or electric rotary hammer drill.

Boring B12 was unpaved.

Borings B1, B2, and B9 through B12 were advanced to a terminal depth of one feet bgs. Borings B3, B5, and B6 were advanced to a terminal depth of 25 feet bgs. Boring B4 was advanced to a terminal depth of 20 feet bgs due to drilling refusal. Borings B7 and B8 were advanced to a terminal depth of 15 feet bgs.

Borings SV-13, SV-15, and SV-17 through SV-26 were advanced to a terminal depth of five feet bgs. Borings SV-14 and SV-16 were advanced to a terminal depth of four feet bgs due to drilling refusal. 2144

3.6 Soil Sampling
Soil samples were collected from borings B1 through B12 using a two-foot long by 1.5-inch diameter sampler with a two-foot long acetate liner and sampling point. The sampler was advanced by the directpush drill rig using four-foot by 1.25-inch diameter hollow rods with the inner rods in place. At approximately one foot above the desired sampling depth, an inner rod was removed and the sampler was advanced to the desired sampling depth to allow undisturbed soil to enter the sampling liner. The sampler was retrieved from the subsurface and the soil-filled liner was removed.

Each acetate liner was cut using a pipe-cutter. Samples were collected from the lower half of the liner using a disposable plastic syringe and retained in two sodium bisulfate-preserved volatile organics analysis (VOA) vials in accordance with United States Environmental Protection Agency (EPA) Method 5035 sampling protocol. The remainder of the lower half of the liner was capped on either end with Teflon tape and plastic caps. The capped liners and VOA vials were labeled for identification and stored in an iced cooler. The soil in the upper half of the liner was visually inspected for discoloration, monitored for odors, classified in accordance with the Unified Soil Classification System, placed in a sealable plastic bag, and field-screened with a photoionization detector (PID). None of the samples exhibited discoloration or an odor and none of the PID readings suggested the presence of elevated volatile organics concentrations.

Soil samples were collected from borings B1, B2, and B9 through B12 at one foot bgs. Soil samples were collected from borings B3, B5, and B6 at five, 10, 15, 20, and 25 feet bgs. Soil samples were collected from boring B4 at five, 10, 15, and 20 feet bgs. Soil samples were collected from borings B7 and B8 at five, 10, and 15 feet bgs.

3.7 Initial Soil Gas Sampling
Soil Gas Probe Construction
Soil gas probes screened at five feet bgs in borings B3 through B8 were constructed within the boreholes upon completion of soil sampling or drilling to the terminal depth. Boreholes were backfilled with dry, granular bentonite to approximately six inches below the desired sampling depth. A new section of ¼-inch diameter polyethylene tubing with a new ¼-inch diameter polypropylene filter at the terminal end was inserted into the borehole to the desired sampling depth. One-inch diameter polyvinyl chloride (PVC) casing was used as a guide for the tubing to ensure that the desired sampling depth was achieved. Sand was poured into the boring annulus to form an approximately one-foot long sand pack around the polypropylene filter, at which time the PVC piping was withdrawn. Approximately one foot of dry, granular bentonite was placed atop the sand pack and the remainder of the borehole was backfilled with hydrated bentonite to the ground surface to form a seal. The sampling end of the tubing was fitted with a valve and the probe was labeled for identification.

Soil Gas Sampling Methodology
Soil gas samples were collected in general accordance with the July 2015 Department of Toxic Substances Control (DTSC) and Los Angeles Regional Water Quality Control Board (LARWQCB) “Advisory – Active Soil Gas Investigations.”

Soil gas samples were collected using one-liter, stainless-steel, cylindrical SUMMA canisters. The sampling containers were provided by SunStar Laboratories, Inc. (SunStar) a state-certified laboratory [California Department of Public Health (CDPH) Environmental Laboratory Accreditation Program (ELAP) certificate number 2250] in Lake Forest, California, which subjected each canister to a rigorous cleaning process using a combination of dilution, heat, and high vacuum. After cleaning, the canisters were batch certified to be free of target contaminants to a specified reporting limit via gas chromatography/mass spectroscopy prior to delivery.

Partner received the SUMMA canisters evacuated to approximately 30 inches of mercury. The SUMMA canisters were fitted with stainless-steel flow controllers, which Sunstar calibrated to maintain constant flow (approximately 0.1 liter per minute) for approximately five to 10 minutes of sampling time.

Each probe was allowed to equilibrate for a minimum of two hours after installation prior to sampling. After equilibration, the sample tubing and sampler screen were purged of ambient air using a plastic syringe.

Tracer liquid isopropyl alcohol was placed around each probe at the ground surface while sampling to detect ambient air intrusion. The tracer gas was not detected in any sample, indicating that the integrity of the bentonite seal was maintained. Once the ambient air was purged, the sampling end of the tubing was fitted to the sampling canister and the port valve was opened, causing air to enter the sample container due to the pressure differential. Partner closed the valves after the canister was evacuated to approximately one to two inches of mercury, with pertinent data (e.g., time, canister vacuum) recorded at the start and end of sampling.

The SUMMA canisters were labeled for identification and stored away from direct sunlight prior to analysis.

Soil gas samples were collected from borings B3 through B8 at five feet bgs.

3.8 Soil Gas Samples Collected by Optimal
Based on the results of the initial investigation, Optimal was contracted to conduct soil gas sampling onsite. Soil gas sampling at borings SV-13 through SV-26 was performed by hydraulically pushing soil gas probes to a depth of four or five feet bgs. An electric rotary hammer drill was used to drill a one inch diameter hole through the overlying surface to allow probe placement when required. The same electric hammer drill was used to push probes in areas of resistance during placement.

At each sampling location an electric vacuum pump set to draw 0.2 liters per minute (L/min) of soil gas was attached to the probe and purged prior to sample collection. Soil gas samples were obtained in SGE gastight syringes by drawing the sample through a luer-lock connection which connects the sampling probe and the vacuum pump. Samples were immediately injected into the gas chromatograph (GC)/purge and trap after collection. New tubing was used at each sampling point to prevent cross contamination.

Analyses were performed on a laboratory grade Hewlett Packard model 5890 Series II gas chromatograph equipped with a Hewlett Packard model 5971 Mass Spectra Detector and Tekmar LSC 2000 Purge and Trap.

An SGE capillary column using helium as the carrier gas was used to perform the analysis. The results were collected on a personal computer utilizing Hewlett Packard's 5971 MS and chromatographic data collection and handling system.

A replicate analysis (duplicate) was run to evaluate the reproducibility of the sampling system and instrument. The difference between samples did not vary more than 20%. Blanks were run at the beginning of each workday and after calibrations. The blanks were collected using an ambient air sample. These blanks checked the septum, syringe, GC column, GC detector and the ambient air. Contamination was not found in any of the blanks analyzed during this investigation. Blank results are given along with the sample results.

A tracer gas was applied to the soil gas probes at each point of connection in which ambient air could enter the sampling system. These points include the top of the sampling probe where the tubing meets the probe connection and the surface bentonite seals. Isobutane was used as the tracer gas. No isobutane was found in any of the samples collected. The standard purge volume of three volumes was purged in accordance with the July 2015 DTSC/RWQCB Advisory for Active Soil Gas Investigations. A shut-in test was conducted prior to purging or sampling each location to check for leaks in the above-ground sampling system. The system was evaluated to a minimum measured vacuum of 100 inches of water. The vacuum gauge was calibrated and sensitive enough to indicate a water pressure change of at least 0.5 inches.

3.9 Post-Sampling Activities
Probes were removed from the subsurface and the boreholes were backfilled with hydrated bentonite chips following sampling activities. Boreholes advanced in improved areas were capped with concrete to match existing ground cover after being backfilled.

No significant amounts of derived wastes were generated during this investigation. 2147

4.0 LABORATORY ANALYSIS

4.1 Laboratory Analysis
Partner collected 33 soil samples and six soil gas samples on July 21, 2106, which were transported on July 22, 2016, in an iced cooler (soil) or at room temperature (soil gas) under proper chain-of-custody protocol to SunStar, for analysis. Based on field-screening results, visual observations, and/or olfactory observations, one soil sample from borings B1 through B12 (12 soil samples total) was analyzed for carbon chain total petroleum hydrocarbons (TPH-cc) in accordance with EPA Method 8015C and VOCs in accordance with EPA Method 8260B. Each of the six soil gas samples collected by Partner was analyzed for VOCs in accordance with EPA Method TO-15. The remaining soil samples were placed on hold at the laboratory.

Optimal, a state-certified mobile laboratory (CDPH ELAP certificate number 2779) that was present on-site, collected 14 soil gas samples, two purge test samples, and one duplicate sample on July 29, 2016, which were immediately loaded into the gas chromatograph/mass spectrometer (GC/MS) for analysis. Each soil gas sample was analyzed for VOCs in accordance with Modified EPA Method 8260B.

4.2 Laboratory Analytical Results
Laboratory analytical results are included in Appendix B and discussed below.

4.2.1 Soil Sample Analytical Results
None of the analyzed soil samples contained detectable concentrations of TPH-cc or VOCs above their respective laboratory Reporting Limits (RL).

Refer to Table 2 and 3 for a summary of the soil sample TPH-cc and VOCs laboratory analysis results, respectively.

4.2.2 Soil Gas Sample Analytical Results
Various VOCs including tetrachloroethene (PCE), trichloroethene (TCE), ethylbenzene, m,p-xylene, and oxylene were detected in the analyzed soil gas samples above laboratory RLs. No other VOCs were detected above laboratory RLS.

Refer to Table 4 for a summary of the soil gas sample VOCs laboratory analysis results. 2148

5.0 DISCUSSION AND CONCLUSIONS

5.1 Regulatory Agency Guidance
Department of Toxic Substances Control Attenuation Factor and Regional Screening Levels Regional Screening Levels (RSLs) (formerly Preliminary Remediation Goals) are generic, risk-based chemical concentrations developed by the EPA Region 9 for use in initial screening-level evaluations. RSLs combine human health toxicity values with standard exposure factors to estimate contaminant concentrations that are considered to be health protective of human exposures over a lifetime through direct-contact exposure pathways (e.g., via inhalation and/or ingestion of and/or dermal contact with impacted soil and/or indoor air). RSLs are not legally enforceable standards, but rather are considered guidelines to evaluate if potential risks associated with encountered chemical impacts may warrant further evaluation.

The DTSC Office of Human and Ecological Risk (HERO) developed California-Modified RSLs based on a review of 1) the differences in methodology between PRGs and RSLs 2) RSL concentrations, and 3) recent toxicity values.

While soil gas detections are not immediately comparable to the indoor air quality guidelines within the RSLs, the DTSC issued recommended default attenuation factors of 0.05 (subslab sampling locations) and

0.002/0.001 (residential/commercial contaminant source sampling locations) for sites where the attenuation factor for the building slab is unknown or cannot be determined in the October 2011 document Guidance for the Evaluation and Mitigation of Subsurface Vapor Intrusion to Indoor Air. With the subsurface contaminant concentrations and default attenuation factors, the associated contaminant concentrations in indoor air can be estimated as Calculated Residential and Commercial/Industrial Soil Gas Screening Levels (SGSLs).

5.2 Discussion
None of the analyzed soil samples contained detectable concentrations of TPH-cc or VOCs above laboratory RLs, and the laboratory RLs were below applicable Maximum SSLs (TPH-cc) or residential and commercial/industrial RSLs (VOCs).

Of the detected concentrations of VOCs above laboratory RLs, none exceeded the calculated residential or commercial/industrial SGSLs. No other VOCs were detected above laboratory RLs, which are below calculated residential or commercial/industrial SGSLS.

Based on these concentrations, there is evidence of de minimis release of hazardous materials from the subject property. The detected VOC concentrations in soil gas do not exceed applicable screening levels.

Based on these findings, there does not appear to be a discernible vapor intrusion condition to the subject property and the detections of VOCs in soil gas do not appear to represent a threat to human health or the environment.

5.3 Summary and Conclusions
Partner conducted a Phase II Subsurface Investigation at the subject property to identify the location of the former on-site USTs, tankholds, and/or other associated features and to investigate the potential impact of petroleum hydrocarbons and VOCs to soil and soil gas as a consequence of a release or releases from the 2149

on-site grain handling facility. The scope of the Phase II Subsurface Investigation included a geophysical survey and 26 soil borings. Twelve soil samples were analyzed for TPH-cc and VOCs, and 21 soil gas samples were analyzed for VOCs including one replicate.

The geophysical survey identified one large anomaly in the eastern portion of the subject property to the west of Building B, under the canopy. The location and shape of the anomaly, which consisted of a backfilled excavation, generally corresponded to the location of the former USTs. No large metallic features were identified, which confirms that the USTs have been removed. The geophysical survey also identified one large anomaly resembling a septic system to the north of Building A.

Subsurface lithology encountered in the upper 20 feet bgs consisted predominantly of brown, very fine grained, medium dense, damp, silty sand (SM). From 20 to 25 feet bgs, the subsurface consists predominantly of brown, very fine to coarse grained, dense, damp, poorly graded, sand (SP). Groundwater was not encountered.

There were no TPH-cc or VOCs detected in soil in excess of applicable laboratory RLs which were below Maximum SSLs (TPH-cc) and residential and commercial/industrial RSLs (VOCs).

Of the detected concentrations of VOCs above applicable laboratory RLs in soil gas, none exceeded the calculated residential or commercial/industrial SGSLs. No other VOCs were detected above applicable laboratory RLs, which are below the calculated residential or commercial/industrial SGSLS.

Based on these concentrations, there is evidence of de minimis release of hazardous materials from the subject property. The detected VOCs concentrations in soil gas do not exceed applicable screening levels.

Based on the Subsurface Investigation, there does not appear to be a discernible vapor intrusion condition to the subject property and the detections of VOCs in soil gas do not appear to represent a threat to human health or the environment. Partner recommends no further investigation with respect to the on-site grain handling facility at this time.

Dup = replicate analysis (duplicate)^Calculated soil gas screening levels (SGSLs) for soil gas concentrations were derived by dividing the June 2016 Department of Toxic Substances Control (DTSC) or May 2016 United States Environmental Protection Agency (EPA) Regional Screening Level (RSL) with an attenuation factor of 0.05 for sub-slab samples or with an attenuation factor of 0.002 for residential settings and 0.001 for commercial/industrial settings for soil gas samples deeper than sub-slab samples. DTSC RSLs are provided in the June 2016 DTSC Human and Ecological Risk Office (HERO) Human Health Risk Assessment (HHRA) Note 3.

Dear Ms. Ponce:

This letter presents the results of the soil vapor investigation conducted by Optimal Technology (Optimal), for Partner Engineering & Science, Inc. on July 29, 2016. The study was performed at 5355 E. Airport Dr., Ontario, California.

Optimal was contracted to perform a soil vapor survey at this site to screen for possible chlorinated solvents and aromatic hydrocarbons. The primary objective of this soil vapor investigation was to determine if soil vapor contamination is present in the subsurface soil.

Gas Sampling Method
Gas sampling was performed by hydraulically pushing soil gas probes to a depth of 4.0-5.0 feet below ground surface (bgs). An electric rotary hammer drill was used to drill a 1.0-inch diameter hole through the overlying surface to allow probe placement when required. The same electric hammer drill was used to push probes in areas of resistance during placement.

At each sampling location an electric vacuum pump set to draw 0.2 liters per minute (L/min) of soil vapor was attached to the probe and purged prior to sample collection. Vapor samples were obtained in SGE gas-tight syringes by drawing the sample through a luer-lock connection which connects the sampling probe and the vacuum pump. Samples were immediately injected into the gas chromatograph/purge and trap after collection. New tubing was used at each sampling point to prevent cross contamination.

All analyses were performed on a laboratory grade Hewlett Packard model 5890 Series II gas chromatograph equipped with a Hewlett Packard model 5971 Mass Spectra Detector and Tekmar LSC 2000 Purge and Trap. An SGE capillary column using helium as the carrier gas was used to perform all analysis. All results were collected on a personal computer utilizing Hewlett Packard's 5971 MS and chromatographic data collection and handling system. 2369 Rutland Place, Thousand Oaks, CA 91362 • Toll Free (877) S 1667 Cross Bridge Place, Thousand Oaks, CA 91362 • Toll Free (877) SOIL GAS (764-5427) • (818) 734-6230 • Fax (818) 734-6235 OIL GAS (764-5427) • (818) 734-6230 • Fax (818) 734-6235

Quality Assurance
5-Point Calibration
The initial five point calibration consisted of 20, 50, 100, 200 and 500 ul injections of the calibration standard. A calibration factor on each analyte was generated using a best fit line method using the HP data system. If the r2 factor generated from this line was not greater than

0.990, an additional five point calibration would have been performed. Method reporting limits were calculated to be 0.01-1.0 micrograms per Liter (ug/L) for the individual compounds.

A daily calibration check and end of run calibration check was performed using a pre-mixed standard supplied by Scotty Analyzed Gases. The standard contained common halogenated solvents and aromatic hydrocarbons (see Table 1). The individual compound concentrations in the standards ranged between 0.025 nanograms per microliter (ng/ul) and 0.25 ng/ul.

Sample Replicates
A replicate analysis (duplicate) was run to evaluate the reproducibility of the sampling system and instrument. The difference between samples did not vary more than 20%.

Equipment Blanks
Blanks were run at the beginning of each workday and after calibrations. The blanks were collected using an ambient air sample. These blanks checked the septum, syringe, GC column, GC detector and the ambient air. Contamination was not found in any of the blanks analyzed during this investigation. Blank results are given along with the sample results.

Tracer Gas Leak Test
A tracer gas was applied to the soil gas probes at each point of connection in which ambient air could enter the sampling system. These points include the top of the sampling probe where the tubing meets the probe connection and the surface bentonite seals. Isobutane was used as the tracer gas. No Isobutane was found in any of the samples collected.

Purge Volume
The standard purge volume of three volumes was purged in accordance with the July 2015 DTSC/RWQCB Advisory for Active Soil Gas Investigations. 2254

Page 3 of 3 ends

Shut-in Test
A shut-in test was conducted prior to purging or sampling each location to check for leaks in the above-ground sampling system. The system was evaluated to a minimum measured vacuum of 100 inches of water. The vacuum gauge was calibrated and sensitive enough to indicate a water pressure change of at least 0.5 inches.

Scope of Work
To achieve the objective of this investigation a total of 15 vapor samples were collected from 14 locations at the site. Sampling depths, vacuum readings, purge volume and sampling volumes are given on the analytical results page. All the collected vapor samples were analyzed on-site using Optimal’s mobile laboratory.

Subsurface Conditions
Subsurface soil conditions at this site were predominately silty-sand from ground surface to 5.0 feet bgs. These soil conditions offered sampling flows at 0” water vacuum. Depth to groundwater was unknown at the time of the investigation.

Results
During this vapor investigation three samples contained levels of Tetrachloroethene (PCE). PCE levels ranged from 0.12 ug/L to 0.23 ug/L. None of the other compounds listed in Table 1 above were detected above the listed reporting limits. A complete table of analytical results is included with this report.

Disclaimer
All conclusions presented in this letter are based solely on the information collected by the soil vapor survey conducted by Optimal Technology. Soil vapor testing is only a subsurface screening tool and does not represent actual contaminant concentrations in either the soil and/or groundwater. We enjoyed working with you on this project and look forward to future projects.

SURROUNDING SITES: SEARCH RESULTS
Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

A soil map in a soil survey is a representation of soil patterns in a landscape. Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO) soil survey maps.

SSURGO: Soil Survey Geographic Database
Source: Department of Agriculture, Natural Resources Conservation Service (NRCS) Telephone: 800-672-5559
SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Service, mapping scales generally range from 1:12,000 to 1:63,360. Field mapping methods using national standards are used to construct the soil maps in the Soil Survey Geographic (SSURGO) database. SSURGO digitizing duplicates the original soil survey maps. This level of mapping is designed for use by landowners, townships and county natural resource planning and management.
