1.0 INTRODUCTION

Clayton Group Services, Inc (Clayton), a Bureau Veritas Cotupany, on behalf of Weiand Automotive Industries, Inc (Weiand), has prepared this Soil Vapor Extraction System Operation andMaintenance, Third Quarter Report, for the Soil Vapor Extraction (SVE) system at the Weiand Automotive Property located at 211612324 North San Fernando Road, Los Angeles, California (the Site, Figure 1 ) This is the third of four Quarterly Reports to be submitted to the D~partment of Toxic Substances Cont1.01 (DTSC) as set forth in Section 8 0 ofthe Removal Action Workplan (RAW), prepared by MWH Americas, Inc , dated February 2003

This report provides a summary of all data collected during the third quarter of operation including analytical laboratory reports, field data sheets, and field observations, as well as an estimated calculation of mass emo ovals for both tetrachloroethene (PCE) and total volatile organic compounds (VOCs) This quarterly report also includes a summary of the second quarter vapor well monitoring activities

The following table summarizes the scheduled dates of SVE system operation

I Quarter Dates of Operation

First Quarter May 25, 2005 to August 30, 2005

1.1 SITE DESCRIPTION

Second Quarter

Fourth Quarter

The Site is located on the west side of North San Fernando Road, just north of Verdugo Road in Los Angeles, California (Figure 1) The Site is rectangular in shape and consists of an office building, two former warehouse buildings, and a former machining operations building (Figure 2) The remaining site area is paved with asphalt

August 31,2005 to November 22, 2005 ~.;~=#&5:g$&2$$$6@5;~$;~~&~4$t2;z2~Q,&[;i

March 2006 to May 2006

The Site is currently leased to a car dealership Recently the tenant has improved the property by upgrading the office building and former machining operations building, and has repaved the entire area between the two buildings to accommodate the car dealership operations Currently, the former machining building is utilized for automobile maintenance and the office building is used by dealership employees

* Included in subject report

2.0 REGIONAL AND SITE GEOLOGY

The Site is located within the Narrows of the Los Angeles River The Narrows is a steep sided, alluvial filled valley that is approximately five miles long and varies in width The valley resulted fiom the erosion of the surrounding hills and alluvial fans, with subsequent deposition of the resulting sediments by the Los Angeles River The Narrows is considered to be the mouth of the San Fernando Valley Groundwater Basin (Environmental Resources Management, 2000)

Site-specific geology consists of interbedded layers of unconsolidated alluvial sediments ranging from sands, silty sands, and silts to a depth of approximately 20 to 25 feet below ground surface (bgs) From below approximately 25 feet bgs clay units ranging in thickness from approximately two to nine feet are present with an apparent southward dip Below these clay units, coarse grained sand and gravely sand units are present to the total depth investigated of approximately 41 feet bgs

3.0 SVE SYSTEM CONSTRUCTION AND START UP

The 500 standard cubic foot per minute (scfm) SVE: system was assembled and constructed on the Site during April and May 2005 per the design outlined in the RAW The system is located at the northeast corner of the former machining operations building One duel nested well (SVE-1) with a shallow interval screened fiom 4 to 29 feet bgs and a deep screened interval fiom 31 5 to 36 feet bgs was connected to the SVE: system The SVE system was started on May 25, 2005 under South Coast Air Quality Monitoring District (SCAQMD) Permit Number E'72803 (Appendix A) The extracted air. is treated by three, 2,000-pound vessels of granular activated carbon The SVE system location is shown on Figure 2 ,

4.0 SVE SYSTEM OPERATION AND MAINTENANCE

Routine operation and maintenance (O&M) was performed throughout the quarter on the SVE system Values for temperature, pressure/vacuum, flow, and vapor concentration using a photo ionizing detector (PID) calibrated to hexane were recorded at the system inlet (before the first carbon vessel), outlet (after the third carbon vessel), and at both system midpoints (between carbon vessels one and two and carbon vessels two and three) PID readings at each well head, hours of system operation, and general observations were recorded and system maintenance was also performed during each O&M visit The values of system flow, pressure, and temperature, along with laboratory analytical results of influent vapor samples were used to calculate contaminant mass removal quantities

4..1 SYSTEM OPERATION MONITORING

The SVE system operates according to the requirements and limitations set forth in the SCAQMD Perrnzt to Constn~ct and Operate No F72803, dated January 4,2005 (Appendix A) The Permit specifies that the inlet VOC concentration shall not exceed 2,536 parts per million per unit volume (ppm [vlv]) as hexane

Below is a summary of the O&M frequency requirements according to the Permit, based on PID readings taken at the system inlet location:

SCAQMD Permit Monitoring Frequency Requirements

Primary Vessel Inlet Concentrat~on Momtoring Frequency

1,268 to 2,536 845 to 1,267

ppm (vlv) - parts per million per unit volume

In order to keep the system in compliance with the Permit, it was necessary to open the dilution air valve approximately 10% during the ongoing operation of the SVE system

The following table contains a partial summary of O&M data for all visits to the site between November 23,2005 and March 2,2006:

O&M data for each visit was recorded on daily field report forms Copies of the O&M field data forms are included as Appendix B and a complete summary of' all O&M data is tabulated in Table 1

During the December 27; 2005 and Februiuy 28; 2006 O&M visits; the SVE system was found not in operation due to power outage

On December 12, 2005, the SVE system was shut down by Clayton personnel due to total VOC effluent concentrations exceeding allowable concentrations acco~ding to the SCQAMD Permlt The granular activated carbon was subsequently changed and the system restarted on December 22, 2005

4..2 VAPOR SAMPLE COLLECTION AND ANALYSIS

As required by the Permit, vapoI samples were collected monthly during the third quarter of SVE operation

4.3 SAMPLING AND ANALYSIS

Durmg the December 29,2005; January 24, 2006; and March 2,2006 sampling events, one vapor sample each fiom the system inlet, second midpoint (i e , between the second and third carbon vessels), and system outlet were collected

All samples were collected in summa@ canisters in compliance with United States Environmental Protection Agency (EPA) Analytical Method TO-15

The samples were submitted on the same day under chain of custody documentation to Severn Trent Laboratories, Inc (STL) and analyzed for VOCs by EPA Method TO-15, total non-methane organic compounds (TNMOC) as hexane by SCAQMD 25 1 Modified or. total VOCs as hexane (C6-CI2) by EPA Method TO-15, as specified in the SCAQMD permit, and fixed gases by American Standards for Testing Materials (ASTM) Method Dl946 as requested by the DTSC STL is a California State Certified Laboratory certified under the California E,nvironmental Laboratory Accreditation Program (ELAP)

For the January 24,2006 sampling event, the system vapor samples were analyzed for TNMOC by SCAQMD 25 1 Modified and total VOCs as hexane (C6-CU) by EPA Method TO-15

4.4 ANALYTICAL RESULTS

As reflected in p~evious analytical characterizations, the inlet vapor stream is predominantly comprised of PCE

The SCAQMD Permit specifies VOC emission concentration limits for. the outlet vapor analytical sample as noted below:

TNMOCITotal VOCs - 6 ppm (vlv) (maximum) PCE - 5 ppm (vlv) (maximum) Benzene - 0 25 ppm (vlv) (maximum) Vinyl Chloride - 0 2 5 ppm (vlv) (maximum)

In general, outlet sample analytical results showed compound concentrations either below laboratory detection limits or at relatively low levels

The following summary table presents select laboratory analytical results from the third quarter of operation sampling events:

4.6 MASS RElMOVAL CALCULATIONS

The SVE field values of temperature, pressure, and flow (related to the inlet sample collection port) from each O&M visit and laboratory analytical results of influent vapor samples were used to calculate approximate mass removal quantities for total VOCs and PCE The calculations for mass removal are described in Appendix D and presented in Table 1

Through March 2,2006 (end of the third quarter of SVE system operation), it is estimated that the SVE system has removed approximately 988 pounds oftotal VOCs from the subsurface at the Site Of the total VOCs removed, approximately 128 pounds was PCE Figures 3 and 4 show the cumulative mass of total VOCs and mass ofPCE removed, respectively

5.0 VAPOR MONITORING WELL OUARTERLY MONITORING

At the March 2005 meeting between the DISC and Clayton, it was agreed to install five soil vapor monitoring wells around the SVE well at the Site The objective of the vapor monitoring wells is to both monitor the effectiveness ofthe SVE system in reducing the chemical concentrations in the subsurface at the site and to determine the radius of influence (ROI) of the SVE system The location of the soil vapor monitoring wells was determined based on the location of the SVE well and the lateral distribution of VOCs historically detected at the Site as presented on Figure 5 On October 11,2005, Clayton submitted a document entitled Workplan for Installatton ojFive Soil Vapor Monitoring Wklis at the iVez'andAwtomotzve Property

On November 3 and 4, 2005, Clayton installed five multi-depth soil vapor well clusters at the Site, with permanent vapor probe sampling inlets set at approximately 5, 15, 25, and 35 feet bgs

The depths of the vapor probes within each of the five vapor well clustns iue summarized below:

VMP-1 : 5,21,28 and 36 feet bgs VMP-2 : 5, 14,26 and 36 feet bgs

0 VMP-3 : 7,18,26 and 35 feet bgs 0 VMP-4 : 9, 18,27 and 36 feet bgs

VMP-5 : 9,17,27 and 36 feet bgs

The locations of the vapor monitoring wells are shown on Figure 6

5..1 SECOND QUARTER SAMPLING

On March 2, 2006, Clayton conducted the second quarter vapor well monitoring at the Site Jones Environmental Laboratories, a California State Certified Laboratory certified under the California ELAP, supplied an onsite mobile laboratory and technician to collect and analyze the soil vapor samples Sampling of the so11 vapor probes was conducted in general accordance with the DTSC and California Regional Water Quality Control Board, Los Angeles Region (CRWQCB-LA) Advzsovy - Actzve Sod Gas Investzgahons, (Advisory) dated Tanuary 28,2003

During the first quarter sampling event, a step purge test was conducted Based on this test, the '7-volume purge was selected and used for. all subsequent soil vapor quarterly sampling events at the Site Soil vapor was withdrawn from the tubing using a resttictive flow pump equipped with a rotometn at a rate of200 cubic centimeters per minute Enough vapor was purged to flush seven dead volumes of soil vapor from the probe interval The next 20 cubic centimeters of vapor was withdrawn in a sampler, plugged, and immediately transferred to the onsite mobile laboratory for analysis Each soil vapor sample was analyzed for VOCs using EPA Method 8260B A total of' 19 of the 20 soil vapor probes were sampled during the second quarter sampling event Vapor probe VMP-2-14 was not sampled due to a blockage in the vapor probe

Additionally, as specified in the RAW, 10% of the samples were collected as duplicates in summa@ canisters (VMP-2-36DUP and VMP-4-18DUP) and submitted to a stationary laboratory for quality assurance / quality control (QNQC) purposes urnm ma' canister samples were submitted to STL and analyzed for VOCs in accordance with EPA Method TO-15 using the 10-14 analyte list

The vacuum of each monitoring probe was measured using a passive hand held instrument and recorded by Clayton personnel in inches of water The vapor pressure readmgs are included in Table 4 and illustrated in cross-section in Figure 7

5.1.1 Second Quarter Sampling Results

Results of the second quarter vapor monitoring well sampling event indicated the presence of VOCs in soil vapor at the Site PCE, the primary contaminant of concem, was detected in all soil vapor samples collected at concentrations ranging from 2 9 micrograms per liter. (pg/l) in sample VMP-1-21 to 399 pg/l in sample VMP-4-18

The 1,esults from the mobile laboratory are reported in pg/L The r.esults ofthe duplicate samples collected in summa@ canisters are reported in parts per billion per unit volume (ppb [v/v]) To compare these results, the ppb (vlv) values are conver.ted into pgll as described in Appendix D The results ofthe duplicate sample VMP-2-36DUP are

consistent with the results of the primary sample The results of duplicate sample VMP-4-18DUP are up to five orders of magnitude higher than the primary sample (benzene was less than 0 01 pg/l in primary sample and 890 pg/l in the duplicate sample The inconsistency of these results could not be determined; however, it may be attributable to several factors including the different laboratories utilized for analyses, collection methods, and time of sample collection

BTEX compounds were detected in several of the samples collected during the monitoring event Excluding the VMP-4- 18DUP sample mentioned above, the maximum detected BTEX concentrations were; B - 2 pg/l (VMP-2-36DUP), T - 45 pg/l (VMP-2- 36), E - 3 1 pgll (VMP-2-36), and X - 60 pg/l (VMP-2-36)

The results of the second quarter vapor well monitoring event are summarized in Table 4 and shown on Figures 6 and 7 The analytical laboratory reports are included as Appendix E

6.0 SUMMARY AND CONCLUSIONS

Based upon the results of the quarterly O&M vapor extraction system (VES) monitoring the following conclusions can be made

Evaluation of the SVE system O k M records indicates that the SVE as designed is effectively extracting VOCs fiom the subsurface

There were three vapor sampling events during the third quarter of SVE operation: December 29,2005; January 24,2006; and March 2,2006 The concentration of PCE in the influent vapor stream has been decreasing since June 2005 (1 1 ppm vlv) with the exception of the last measurement in March 2006 (0 790 ppm vlv), where a slight increase was observed compared to the previous month The overall rate of PCE removal is depicted in Figure 4

During the third quarter of operation, the SVE system removed an estimated 378 pounds of total VOCs, 19 pounds of which was PCE From May 2005 through March 2,2006 the SVE system has removed approximately 988 pounds, 128 of which was PCE

The influent vapor stream continues to contain BTEX compounds These chemicals were not initially identified as targets of ~emediation The continued presence of these compounds reduces the effective life of the GAC and has resulted in more frequent carbon I eplacement

VES Monitovzng Well Sampling

The second quarter of monitoring well sampling was conducted on March 2,2006, during the third quarter of SVE system operation Analytical results indicated concentrations of PCE in soil vapor ranging horn 2 9 pgil to 399 ygil in vapor monitoring probes VMP-1-21 and VMP-4-18, respectively

In general the VOC concentrations detected in vapor monitoring wells in the second quarter monitoring event are lower than those measured du~ing the first quarter monitoring event in November 2005 and the baseline soil vapor concentrations reported in the May 2004 investigation However, PCE concentrations in vapor probes VMP-2-5, VMP-2-26, VMP-4-8, VMP-4-36, VMP-5-17, and VMP-5-27 increased compared to the PCE concentrations detected during the first quarter monitoring event Table 4 summarizes the vapor well monitoring results @-

MASS REMOVAL AND UNIT CONVERSION CALCULATIONS

Appendix D Mass Removal and Unit Conversion Calculations

To obtain the value for total VOCs, the analytical values for TNMOC and methane were added together

First, it was necessary to convert the field value ofpressure, measured in inches of Water Column (in WC) to pounds per cubic inch (psi) using the equtt' , lon:

Pressure (psi) = Pressure (in WC) 127.68

Next, it was necessary to convert the field value of flow, measured in actual cubic feet per minute (acfin), to standard cubic feet per minute ( s c h ) The conversion tmnslates the field readings to standard atmospheric temperatu~es (standard temperature Rankine) and pressures This was performed uslng the following equation:

Flow (scfm) = Flow (acfm) [14.7 + psi / 14..7] [520 I460 + Temperature (F)]

Since the laboratory reports the various analytes in % (vlv), ppm (vlv), or ppb (vlv), the concentration of each detected analyte had to be converted first to ppm (v/v) Concentrations reported in % (vlv) (methane and other fixed gases) were multiplied by 10,000 and those reported in ppb (vlv) (PCE and other VOCs) were divided by 1000

Pounds per cubic foot for each analyte in each sample were calculated in a database First the ppm (vlv) values were converted to mg/m3 using the equation:

Concentration (mg/m3) = Concentration (ppmV) x MW 1 23.69

MW is the molecular weight of each analyte and the value 23 69 is the volume in liters of one mole of gas at 60° F or 15 56' C This temperature is the standard to which the actual flow meter readings ate converted to yield s c h Next, the concentrations in mg/m3 were multiplied by 6 24 x to convert the units to pounds per cubic foot (lbl ft3) This factor is calculated by dividing the value of 0 02832 m3/ft3 by 4 536 x lo5 mg/lb

From this point, total pounds of analyte removed between site visits was calculated using the converted values of flow and analyte concentration, and the elapsed time between visits using the following equation:

Total Pounds Removed = scfm (ft3/min) x lb/ ft3 x hours of' operation x 60 (min/hour)

Cumulative pounds removed were then calculated by adding each current value to the previous cumulative value

Unit Conversion Calculation

The ppb (vlv) values are converted to pg/l using the formula pg/1= ppb (vlv) x MWl23 69, where MW is the molecular weight of each analyte The value, 23 69, is the volume in liters of one mole of gas at 60' F or 15 56' C
