VAPOR EXTRACTION SYSTEM WORKPLAN VERNON SANITATION SUPPLY COMPANY 4622 ALCOA AVENUE VERNON, CALIFORNIA INTRODUCTION SCS ENGINEERS - SCS Engineers (SCS) has been retained by Vernon Sanitation Supply Company (Vernon Sanitation) to prepare this Vapor Extraction System Workplan for soils impacted by PCE (perchloroethene, also known as tetrachloroethene) associated with the Vernon Sanitation facility (the Property) at 4622 Alcoa Avenue in Vernon, California The subject site is currently occupied by the warehouse, office and janitorial supply distribution operations of Vernon Sanitation. The location of the Property is shown in Figure 1 This Workplan was prepared at the request of the City of Vernon Environmental Health Department (Vernon EHD) as outlined in their letter dated August 16, 2000. BACKGROUND The Vernon Sanitation site is bounded on the north by a parking lot owned by the City of Vernon. As a part of an environmental investigation of this city -owned property, soil and soil gas investigations were conducted. The results of these investigations (Conservtech, April 1997) identified soils impacted with predominantly PCE, and trace levels of other chlorinated compounds such as TCE and 1,2-DCE. At the request of the Vernon EHD, several additional Phases of investigation were conducted, for both the city -owned property to the north as well as the Vernon Sanitation site. Historical information from these investigations (ConserAech, March 1999) indicates industrial dry cleaning operations at 4622 Alcoa Avenue were destroyed in a 1968 fire. These dry cleaning •operations are the suspected source of the PCE. It appears likely that the fire resulted in the release of PCE, and that fire -fighting efforts (i.e., the application of water) may have aided in the spread and infiltration of PCE to subsurface soils. Conservtech conducted several phases of investigation that document PCE-impacted soils beneath the Property, the city -owned property to the north, and the adjacent streets. In addition, documentation provided in Conservtech's April 1999 report included analytical data and a map showing PCE concentrations and soil vapor sampling locations for the adjacent Packaging Advantage Corporation (PAC) warehouse facility at 4700 Alcoa Avenue, immediately south of the Property. SCS used the results of the previous investigations to produce maps showing PCE concentrations in soil gas in the area. Figures 2, 3 and 4 are maps of the area showing soil gas concentrations of PCE at the 10, 30, and 50 depths below ground surface (bgs). It should be noted that the data shown on these maps were collected over an approximately three-year period by different consultants and laboratories (the consultant and laboratory for the PAC facility were not., SCS ENGINEERS - identified), and may therefore not be directly comparable. However, a relatively consistent picture of the levels and distribution of PCE in soil vapor is shown in these Figures. The highest concentrations of PCE in soil gas, up to 58,000 ug/L-vapor (micrograms per liter in vapor), were detected within the area of the northern building of the Vernon Sanitation facility at a depth of 50 feet bgs. Conservtech drilled one deep boring in this area (designated DB) in July 1999 and collected soil and soil gas samples to a depth of 110 feet bgs. Although elevated concentrations of PCE (up to 78,000 ug/L-vapor) were detected in soil gas from depths of 60 to 90 feet bgs, the corresponding soil samples did not contain detectable concentrations of PCE. Based on this information and an evaluation of sampling methodologies, Conservtech concluded that soil gas results from the 60 to 90-foot samples were questionable, and that soils with the highest concentrations of PCE were located at a depth between 20 and 50 feet bgs. As shown in Figures 2 and 3, at the 10- and 30-1oot depths, the PCE soil gas plume is generally circular in shape with a diameter of approximately 500 feet. TOPOGRAPHIC, GEOLOGIC AND HYDROGEOLOGIC INFORMATION The Property is located on the central portion of the Downey Plain, approximately 0.2 miles south of the- Los Angeles River and at an elevation of approximately 190 feet above mean sea level. According to Bulletin No. 104, Appendix A of the California Department of Water Resources, shallow sediments in this area are of Recent or Pleistocene -age alluvium, derived from the Los Angeles River, and consist of gravels, sands, silts and clays. The results of previous investigations show that subsurface sediments to 110 feet bgs consist predominantly of sands and silts, with occasional clays. The Property is located in the Los Angeles Forebay Area of the Central Groundwater Basin. Bulletin No. 104 indicates that the fast regional aquifer in this area is the Exposition Aquifer between approximately 50 and 200 feet bgs. Based on information obtained from Conservtech's Limited Environmental Site Assessment (March 1999), groundwater was not encountered in a boring drilled to a depth of 110 feet bgs. For the area of the Property, the Los Angeles County Department of Public Works' Fall 1978 Groundwater Contour Map for the Shallow Aquifer of the Coastal Plain shows groundwater at an elevation of —40 feet relative to mean sea level (or approximately 230 feet bgs), with a flow direction to the north. PURPOSE AND SCOPE OF WORK This workplan describes the steps necessary to remediate PCE-impacted soil identified in the area of 4622 Alcoa Avenue in Vernon, California. Long-term land use for the city of Vernon will remain industrial in nature. The remediation action proposed will implement a vapor extraction program that targets areas with PCE concentrations greater than approximately 300 ug/L-vapor in the vadose zone. Potential risk to human health and the environment will be reduced by decreasing the concentrations of PCE in subsurface soils at the Property. SCS ENGINEERS - SCS will provide oversight of the remedial action including installation of the soil vapor extraction (SVE) system, vapor monitoring wells, and maintenance and operation of the SVE system. SOIL VAPOR EXTRACTION SYSTEM INSTALLATION The minimum radius of influence (ROI) demonstrated during the VES Pilot Test wells was approximately 80 feet. This 80-foot ROI was based on a maximum extraction period of approximately one hour. However, based on our experience, the ROI will increase with time, and the installation and operation of multiple vapor extraction wells in the same area will also increase the demonstrable ROI. SCS anticipates that the actual influence of the VES will ultimately be farther than 100 feet. Based on a minimum ROI of 100 feet, the areal extent of PCE in soil, and available locations to install extraction wells, SCS has designed a system with a total of seven vapor extraction wells to remediate the PCE-impacted soils. A map showing the PCE soil gas plume at 10 feet bgs, the two existing and five proposed vapor extraction wells, and the ROI of each extraction well is provided in Figure 5. In addition to the extraction wells (EW1 through EW7), three vapor monitoring wells designated VMWI through VMW3 will be installed as shown in Figure 5. The vapor monitoring wells will be used to monitor the ROI of the system, as well as PCE vapor concentrations in these areas with time. To summarize, the major elements of the proposed system will include: • Two existing vapor extraction wells, EW 1 and EW2. • Five proposed vapor extraction wells designated EW3 through EW7. • Three vapor monitoring wells designated VMWI through VMW3. • Surface and subsurface header system (as conditions allow) to connect the extraction wells to an extraction/treatment system. l • Treatment of extracted vapor with an available thermal/catalytic oxidation unit with a caustic scrubber to neutralize hydrochloric acid generated by the oxidation of the PCE. Details of the proposed remediation system are described in the following sections. Vapor Extraction and Monitoring Wells The SVE system will include extraction wells, to which a vacuum will be applied to draw PCE- containing air from the subsurface, and monitoring wells, which will be used to measure vacuums at various distances from the extraction wells and may be used to introduce air to the subsurface. �i 3 . SCS ENGINEERS - Seven proposed extraction wells (EW 1 through EW7) will be used for VES. All of these wells will be completed with two screened intervals, in the same manner as existing wells EW 1 and EW2; that is screened from approximately 15 to 30 feet bgs and again from 35 to 50 feet bgs. The multiple completion of these wells will allow for the extraction and/or monitoring of individual subsurface zones, in order to control and maximize the recovery of PCE vapors. Locations of these wells are illustrated in Figure 5. These locations were chosen because they are within the area of impacted soil, presumed to be available for the installation of wells (several of the wells are off site), and would affect soils within the impacted area. In addition, three vapor monitoring/air inlet wells (VMWI, 2 and 3) will be installed in the locations indicated on Figure 5. These three wells will be constructed of 0.75-inch diameter PVC with perforations from 20 to 30 feet bgs. Extraction and monitoring wells will be installed using a truck -mounted hollow -stem auger drill rig. Borings will be sampled for logging purposes. Extraction wells will be constructed using 2- inch diameter, flush -threaded, Schedule 40 PVC casing. Factory-slotted.casing with 0.040-inch slots will be used in the screened section. A flush -threaded end cap will be placed at the bottom of the screened section. As outlined above, the vapor monitoring wells will be constructed of 0.75-inch diameter, Schedule 40 PVC casing with perforations in designated region. The well casings will be placed within the center of the hollow -stem augers and annular materials will be placed as the augers are withdrawn. Measurement of backfill depth will be done periodically to assure that bridging has not occurred. Annular materials will consist of a filter pack placed opposite and approximately 1 to 2 feet above the screened section. Filter pack will be Monterey Sand 8x l 6, 6x l 6, or equivalent. A hydrated bentonite seal will be placed on top of the filter pack. The remainder of the annular space will be filled with cement bentonite grout to about 1 foot below grade. Surface completions will be within flush -mounted, traffic - rated boxes or other suitable cover. Drill cuttings will be appropriately contained (i.e., 55-gallon drums, on plastic, or in roll -off containers) and later transported to a licensed disposal site. Treatment Unit The equipment proposed for extraction and treatment of soil vapor will consist of a blower and catalytic vapor destruction unit. The exact specifications of the treatment unit to be used will depend on availability and cost comparison among several manufactured units known to be suitable. The anticipated design flow will be approximately 300 cubic feet per minute (cfm). The treatment unit will require permitting by the South Coast Air Quality Management District (SCAQMD). Details of the treatment.unit will be forwarded to the Vernon EHD at the same time as the SCAQMD permit application is submitted SCS ENGINEERS - The treatment system will be connected to the wells using a series of header pipes. Each wellhead will be fitted with valves to allow adjustment of flow from individual extraction zones, as well as sampling ports to measure flow and/or vapor concentrations. Operation and Maintenance (O&M) Initiation of SVE operation will consist of collection of measurements of pressure/vacuum, field vapor concentrations on the static system, and collection of samples for laboratory analysis, followed by system startup and balancing. Balancing consists of iterative adjustments to the valving and treatment unit to achieve optimal flows while preventing short circuiting. Field measurements will include vapor concentrations using an organic vapor monitor (OVA), flow using a Kurz flow meter capable of taking measurements within a section of piping (converted to. flow in cfm), and vacuum measured using Mangnehelic gauges. During the initial balancing phase, the system may be monitored and adjusted daily or every other day. The interval between monitoring episodes will be gradually lengthened to approximately weekly inspections of the treatment unit, which will include field measurement of flow and concentrations at individual wells. Field monitoring data will be recorded in abound notebook with sequentially numbered data sheets. In addition, at least one vapor sample will be collected for laboratory analysis each month from the inlet and outlet to the treatment system. Additional samples for laboratory analysis will be collected from individual wells as warranted. The system will continue to operate until asymptote concentrations (i.e., no further reduction in vapor concentrations) are reached. Reporting Monitoring reports will be prepared for submittal to the Vernon EHD on a quarterly basis. Monitoring reports will include a narrative describing system operations for the quarter and tabulated or other information on the following: • Results of pertinent field measurements. • Results of laboratory analysis. • Assessment of mass of solvent removed. Reports will include data assessment and conclusions, as appropriate. CONFORMANCE WITH LAWS AND HEALTH AND SAFETY STANDARDS Remediation work done at the site shall be conducted in accordance with all applicable laws and regulations. All necessary permits for this work shall be obtained by SCS, Vernon Sanitation Supply Company, or their subcontractors in a timely manner. All persons performing work at the site shall adhere to appropriate health and safety standards, including necessary monitoring, to insure the protection of on -site workers and others, and off -site residents and workers. SCS ENGINEERS - LIMITATIONS OF DATA All assumptions and estimates described herein are based on release estimates and -limited environmental sampling and analysis. The assumptions in this document regarding the extent of environmental impacts, which may be subject to remedial action, and the scope of work which may be necessary to complete this action, are subject to change based on a number of factors. These factors include, but are not limited to, actual extent and nature of impacted material at the site, definition of impacted soils which may require remediation, requirements of the overseeing regulatory agencies, nature of specific soil transportation and/or treatment/recycling method chosen, health and safety and monitoring requirements, agency requirements for closure, and reporting requirements.

Expires May 18, 2002 "; COMMUNITY SERVICES & WATER DEPARTMENT OFFICE MEMORANDUM TO: Bruce Malkenhorst, City Administrator FROM: Samuel "Kevin" Wilson, Director of Community Services & Water DATE: May 29, 2001 SUBJECT: WATER RATES The Community Services and Water Department staff have determined that a water rate increase is necessary. The City last increased rates on July 1, 1995. Since that time the cost of water has significantly increased. MWD seasonal storage rates have increased by 19.7%, MWD non -interruptible rate have increased by 4.8%. Lease rates have increased by 129%. The Water Department has been advised by the Utilities Department that power rates may increase by as much as 40%. Lastly equipment and material costs have continue rise by approximately 12%. Attached herewith is an Engineers Report, which established the need for an rationale in determining the new rate structure. It is hereby recommended that the water rates be increased as shown in Appendix I of the attachment: SKW/sp c: City Attorney ENGINEERS REPORT WATER RATE INCREASE The City of Vernon last raised it water rates in 1995. Since that time the cost to deliver water has substantially increased. The rates for MWD Water, both non - interruptible and through its seasonal storage program have risen. Lease rates for water rights in the Central Basin have dramatically increase and the utilities section has advised the Water Department that the cost of power that drive the City motors at well sites and pump stations may increase as much :as 40 percent in the next year. Due to these factors a water rate increase is necessary. In 1995 the City of Vernon retained Donald R. Howard consulting Engineers, Inc. to prepare a cost of service and rate design study for the City of Vernon Water Department. The rate design principles established in the Howard study have been utilized to develop the proposed rate increase. The City of Vernon is an Industrial Community located in the southeastern portion of Los Angeles County. The City Water Department purveys water to the majority of the City. California Water Service and Maywood Mutual No. 3 purvey water to customers in portion of the eastern part of the City. Vernon serves approximately 1200 customers with varying consumption requirements. All customers receive a high degree of fire protection. Vernon's water system is currently rated as a Class I System by the insurance services office (ISO), receiving a score of 37.21 out of a maximum 40.0 points. The City's water system consists of nine wells, nine reservoirs and one elevated tank. The total storage capacity is approximately 17 million gallons. In addition the City has several pump stations and approximately 260,000 linear feet of pipe. The City of Vernon Water Department produces most of it water from the central basin. Vernon owns the rights to 8039 acre feet and typically leases additional water pumping rights to accommodate demand. In addition the City has a physical connection to the Metropolitan Water District of Southern California Main. The City purchases MWD during its seasonal storage program when the cost of water in conjunction with the water replenishment rebate make the water less expensive than extracting the water from the ground. The City's water usage has been steadily growing. In 1995 the City produced approximately 9500 a.f. of water. It is projected that this will increase to 12000 a.f. in Fiscal Year 2001-2002. The City is nearing it's pumping capacity and will soon need to either purchase non interruptible water from MWD, provide additional well capacity or develop another water source such as reclaimed water. The City is currently studying which source would prove to be the most economical. In any case, if water demand continues to rise, or the City has a well failure during the summer months when seasonal storage water is unavailable the City will have to purchase non -interruptible MWD water. Since 1995 MWD water rates and Central Basin lease rates have steadily risen. The Water Replenishment Districts Pump Assessment fees have dropped. See Table I for water cost for the past six years. TABLE I WATER COSTS 1995 1996 1997 1998 1999 2000 2001 MWD Non Interruptible Rate $456 $456 $461 $468 $478 $478 $478 MWD Seasonal Storage Rate $295 $295 $310 $317 $328 $342 $353 WRD Pump Assessment Fee $152 $162 $162 $155 $151 $139 $112 Lease Rates $110 $118 $133 $142 $161 $197 $252 WRD Seasonal Storage Credit $112 $120 $120 $120 $120 $135 $162 Additionally equipment material and labor cost have risen approximately 12 percent and electrical rates are expected to rise 40 percent during the next year due to the current energy crisis. Table 2 reflects the percent change in costs. TABLE 2 PERCENT CHANGE 1995 TO 2001 MWD Interruptible Rate +4.8% MWD Seasonal Storage Rate +19.7% WRD Pump Assessment -26.3% Lease Rates +129% WRD Seasonal Storage Credit +44.6% Equipment Material and Labor Costs +12% Electrical Rates +40% The estimated budget for fiscal year 2001-2002 is $6,985,273.00. In 1995 labor expenses accounted for 26.6% of the expenditures. This has dropped to 17.4% in the 2001-02 fiscal year budget. While water productions expenditures have gone from 47.2% of the budget to 53.5% of the budget. Table 3 shows the projected operating budget for Fiscal Year 2001-2002 for the Vernon Water Department. In most cities the primary function of the water purveyor is to provide portable water supply to its residents for consumption. In those cities the consumption rate governs pipe and reservoir sizes and operational costs. Fire service is a secondary consideration. The City of Vernon is unique in that most customers are industrial customers. The water system is designed to suppress fires and to provide industrial water service. The Donald Howard Rate Study was designed to provide a fair share of costs for all customers to insure adequate fire protection and consumable water. The ISO Class I Rating, the highest achievable, that the water department has earned results in lower insurance rates for its customers. The water system was designed to provide proper water flows and pressures to fire hydrants and automatic sprinkler systems during times of emergency. The Donald Howard Rate Study developed the water rate for Vernon's water system, based on the City's need to provide sufficient fire suppression.

The salaries of these needed for production were assigned to the commodity related portion, the balance was assigned to the fire related portion. All accounts related directly to the production and purchasing of water was allocated to the commodity costs and the remainder of the expenses (other than labor expenses) associated with operating the system were allocated to the fire related costs. It was determined that 36.8 percent of the expenses in accounts 1101 through 1103 salaries, and accounts 2120 through 2180 benefits were found to be fire related while 63.2 percent were found to be commodity related. Accounts 5100, 5200, 5210, 5910, 5962 and 5998 (office expense, department supplies, water treatment, equipment maintenance, contract services and administrative expense transfer respectively) were all apportioned by the labor percentage account. Account 5110 and 5120 (pumped water and purchased water) were all apportioned to commodity costs. The commodity related portion of the franchise expense account 5230 is estimated to be 3.5 percent of the total previous year's commodity related cost. The fire related portion of the franchise expense was calculated in a similar manner. Account 5600 was segregated between power for pumping and other expenses. The power for pumping expense was apportioned to the commodity related expense. The balance of the account was apportioned to the fire related expense. The remainder of the expense accounts 4524, 5220, 5300, 5400, 5500, 5700, 5965, 5966, 8400, 8500, 9000 and 9400, along with depreciation were all split equally between fire related and commodity related expenses. The rates are designed such that fire related costs are assigned to customers based on the size of the building and the outside storage (on the basis of square footage). Commodity related expenses were assigned to the regular metered rates. Fifty percent of the commodity related labor was assigned to the meter service charge of regular customers and the other fifty percent was allocated to the commodity charge. The meter service charges were based on meter capacity. The balance of the commodity related costs are assigned to the commodity rate. Earnings from construction charges was subtracted from commodity and fire related expenses at the same percentage rate as were estimated for labor costs. Water loss was assumed to be five percent. Square footage of buildings within the Vernon water service area was assumed to be 43,811,455 square feet and was obtained from the City G.I.S. information. Projected water distribution including loss was assumed to 12,000 acre-feet. The rate design utilized was in accordance with Rate Study 3B of the Donald Howard Consulting Engineers, cost of service and rate design study revised June 28, 1995.

B-3 SCS ENGINEERS— VAPOR EXTRACTION SYSTEM WORKPLAN VERNON SANITATION SUPPLY COMPANY 4622 ALCOA AVENUE VERNON,CALIFORNIA INTRODUCTION SCS Engineers (SCS)has been retained by Vernon Sanitation Supply Company (Vernon Sanitation) to prepare this Vapor Extraction System Workplan for soils impacted by PCE (perchloroethene, also known as tetrachloroethene)associated with the Vernon Sanitation facility (the Property)at 4622 Alcoa Avenue in Vernon, California. The subject site is currently occupied by the warehouse, office and janitorial supply distribution operations of Vernon Sanitation. The location of the Property is shown in Figure 1. This Workplan was prepared at the request of the City of Vernon Environmental Health Department (Vernon EHD) as outlined in their letter dated August 16, 2000. BACKGROUND The Vernon Sanitation site is bounded on the north by a parking lot owned by the City of Vernon. As a part of an environmental investigation of this city-owned property, soil and soil gas investigations were conducted. The results of these investigations(Conservtech, April 1997) identified soils impacted with predominantly PCE,and trace levels of other chlorinated compounds such as TCE and 1,2-DCE. At the request of the Vernon EHD, several additional phases of investigation were conducted, for both the city-owned property to the north as well as the Vernon Sanitation site. Historical information from these investigations(Conservtech, March 1999) indicates industrial dry cleaning operations at 4622 Alcoa Avenue were destroyed in a 1968 fire. These dry cleaning operations are the suspected source of the PCE. It appears likely that the fire resulted in the release of PCE, and that fire-fighting efforts(i.e.,the application of water) may have aided in the spread and infiltration of PCE to subsurface soils. Conservtech conducted several phases of investigation that document PCE-impacted soils beneath the Property,the city-owned property to the north, and the adjacent streets. In addition, documentation provided in Conservtech's April 1999 report included analytical data and a map showing PCE concentrations and soil vapor sampling locations for the adjacent Packaging Advantage Corporation (PAC)warehouse facility at 4700 Alcoa Avenue, immediately south of the Property. SCS used the results of the previous investigations to produce maps showing PCE concentrations in soil gas in the area. Figures 2, 3 and 4 are maps of the area showing soil gas concentrations of • PCE at the 10, 30, and 50 depths below ground surface (bgs). It should be noted that the data shown on these maps were collected over an approximately three-year period by different consultants and laboratories(the consultant and laboratory for the PAC facility were not B-4 J SCS ENGINEERS— identified), and may therefore not be directly comparable. However, a relatively consistent picture of the levels and distribution of PCE in soil vapor is shown in these Figures. The highest concentrations of PCE in soil gas, up to 58,000 ug/L-vapor(micrograms per liter in vapor), were detected within the area of the northern building of the Vernon Sanitation facility at a depth of 50 feet bgs. Conservtech drilled one deep boring in this area(designated DB) in July 1999 and collected soil and soil gas samples to a depth of 110 feet bgs. Although elevated concentrations of PCE(up to 78,000 ug/L-vapor) were detected in soil gas from depths of 60 to 90 feet bgs,the corresponding soil samples did not contain detectable concentrations of PCE. Based on this information and an evaluation of sampling methodologies, Conservtech concluded that soil gas results from the 60 to 90-foot samples were questionable, and that soils with the highest concentrations of PCE were located at a depth between 20 and 50 feet bgs. As shown in Figures 2 and 3, at the 10- and 30-foot depths, the PCE soil gas plume is generally circular in shape with a diameter of approximately 500 feet. TOPOGRAPHIC, GEOLOGIC AND HYDROGEOLOGIC INFORMATION The Property is located on the central portion of the Downey Plain, approximately 0.2 miles south of the-Los Angeles River and at an elevation of approximately 190 feet above mean sea level. According to Bulletin No. 104, Appendix A of the California Department of Water Resources, shallow sediments in this area are of Recent or Pleistocene-age alluvium, derived from the Los Angeles River, and consist of gravels, sands, silts and clays. The results of previous investigations show that subsurface sediments to 110 feet bgs consist predominantly of sands and silts, with occasional clays. The Property is located in the Los Angeles Forebay Area of the Central Groundwater Basin. Bulletin No. 104 indicates that the first regional aquifer in this area is the Exposition Aquifer between approximately 50 and 200 feet bgs. Based on information obtained from Conservtech's Limited Environmental Site Assessment(March 1999), groundwater was not encountered in a boring drilled to a depth of 110 feet bgs. For the area of the Property, the Los Angeles County Department of Public Works' Fall 1978 Groundwater Contour Map for the Shallow Aquifer of the Coastal Plain shows groundwater at an elevation of—40 feet relative to mean sea level (or approximately 230 feet bgs), with a flow direction to the north. PURPOSE AND SCOPE OF WORK This workplan describes the steps necessary to remediate PCE-impacted soil identified in the area of 4622 Alcoa Avenue in Vernon, California. Long-term land use for the city of Vernon will remain industrial in nature. The remediation action proposed will implement a vapor extraction program that targets areas with PCE concentrations greater than approximately 300 ug/L-vapor in the vadose zone. Potential risk to human health and the environment will be reduced by decreasing the concentrations of PCE in subsurface soils at the Property. 2 B-5 SCS ENGINEERS- SCS will provide oversight of the remedial action including installation of the soil vapor extraction (SVE) system, vapor monitoring wells, and maintenance and operation of the SVE system. SOIL VAPOR EXTRACTION SYSTEM INSTALLATION The minimum radius of influence (ROI) demonstrated during the VES Pilot Test wells was approximately 80 feet. This 80-foot ROI was based on a maximum extraction period of approximately one hour. However, based on our experience,the ROI will increase with time. and the installation and operation of multiple vapor extraction wells in the same area will also increase the demonstrable ROI. SCS anticipates that the actual influence of the VES will ultimately be farther than 100 feet. Based on a minimum ROI of 100 feet, the areal extent of PCE in soil, and available locations to install extraction wells, SCS has designed a system with a total of seven vapor extraction wells to remediate the PCE-impacted soils. A map showing the PCE soil gas plume at 10 feet bgs, the two existing and five proposed vapor extraction wells,and the ROI of each extraction well is provided in Figure 5. In addition to the extraction wells(EW I through EW7),three vapor monitoring wells designated VMW1 through VMW3 will be installed as shown in Figure 5. The vapor monitoring wells will be used to monitor the ROI of the system, as well as PCE vapor concentrations in these areas with time. To summarize, the major elements of the proposed system will include: • Two existing vapor extraction wells, EW1 and EW2. • Five proposed vapor extraction wells designated EW3 through EW7. • Three vapor monitoring wells designated VMW1 through VMW3. • Surface and subsurface header system (as conditions allow)to connect the extraction wells to an extraction/treatment system. • Treatment of extracted vapor with an available thermal/catalytic oxidation unit with a caustic scrubber to neutralize hydrochloric acid generated by the oxidation of the PCE. Details of the proposed remediation system are described in the following sections. Vapor Extraction and Monitoring Wells The SVE system will include extraction wells,to which a vacuum will be applied to draw PCE- containing air from the subsurface, and monitoring wells, which will be used to measure vacuums at various distances from the extraction wells and may be used to introduce air to the subsurface. 3 B-6 SCS ENGINEERS— Seven proposed extraction wells (EW1 through EW7)will be used for VES. All of these wells will be completed with two screened intervals, in the same manner as existing wells EW1 and EW2; that is screened from approximately 15 to 30 feet bgs and again from 35 to 50 feet bgs. The multiple completion of these wells will allow for the extraction and/or monitoring of individual subsurface zones, in order to control and maximize the recovery of PCE vapors. Locations of these wells are illustrated in Figure 5. These locations were chosen because they are within the area of impacted soil, presumed to be available for the installation of wells (several of the wells are off site), and would affect soils within the impacted area. In addition, three vapor monitoring/air inlet wells (VMW1, 2 and 3)will be installed in the locations indicated on Figure 5. These three wells will be constructed of 0.75-inch diameter PVC with perforations from 20 to 30 feet bgs. Extraction and monitoring wells will be installed using a truck-mounted hollow-stem auger drill rig. Borings will be sampled for logging purposes. Extraction wells will be constructed using 2- inch diameter, flush-threaded, Schedule 40 PVC casing. Factory-slotted casing with 0.040-inch slots will be used in the screened section. A flush-threaded end cap will be placed at the bottom of the screened section. As outlined above, the vapor monitoring wells will be constructed of 0.75-inch diameter, Schedule 40 PVC casing with perforations in designated region. The well casings will be placed within the center of the hollow-stem augers and annular materials will be placed as the augers are withdrawn. Measurement of backfill depth will be done periodically to assure that bridging has not occurred. Annular materials will consist of a filter pack placed opposite and approximately 1 to 2 feet above the screened section. Filter pack will be Monterey Sand 8x16, 6x16,or equivalent. A hydrated bentonite seal will be placed on top of the filter pack. The remainder of the annular space will be filled with cement-bentonite grout to about 1 foot below grade. Surface completions will be within flush-mounted, traffic- rated boxes or other suitable cover. Drill cuttings will be appropriately contained (i.e., 55-gallon drums, on plastic, or in roll-off containers) and later transported to a licensed disposal site. Treatment Unit The equipment proposed for extraction and treatment of soil vapor will consist of a blower and catalytic vapor destruction unit. The exact specifications of the treatment unit to be used will depend on availability and cost comparison among several manufactured units known to be suitable. The anticipated design flow will be approximately 300 cubic feet per minute(cfm). The treatment unit will require permitting by the South Coast Air Quality Management District (SCAQMD). Details of the treatment unit will be forwarded to the Vernon EHD at the same time as the SCAQMD permit application is submitted. 4 B-7 • SCS ENGINEERS— The treatment system will be connected to the wells using a series of header pipes. Each wellhead will be fitted with valves to allow adjustment of flow from individual extraction zones, as well as sampling ports to measure flow and/or vapor concentrations. Operation and Maintenance (O&M) Initiation of SVE operation will consist of collection of measurements of pressure/vacuum, field vapor concentrations on the static system, and collection of samples for laboratory analysis, followed by system startup and balancing. Balancing consists of iterative adjustments to the valving and treatment unit to achieve optimal flows while preventing short circuiting. Field measurements will include vapor concentrations using an organic vapor monitor(OVA), flow using a Kurz flow meter capable of taking measurements within a section of piping (converted to flow in cfm), and vacuum measured using Mangnehelic gauges. During the initial balancing phase, the system may be monitored and adjusted daily or every other day. The interval between monitoring episodes will be gradually lengthened to approximately weekly inspections of the treatment unit, which will include field measurement of flow and concentrations at individual wells. Field monitoring data will be recorded in a bound notebook with sequentially numbered data sheets. In addition,at least one vapor sample will be collected for laboratory analysis each month from the inlet and outlet to the treatment system. Additional samples for laboratory analysis will be collected from individual wells as warranted. The system will continue to operate until asymptote concentrations(i.e., no further reduction in vapor concentrations)are reached. Reporting Monitoring reports will be prepared for submittal to the Vernon EHD on a quarterly basis. Monitoring reports will include a narrative describing system operations for the quarter and tabulated or other information on the following: • Results of pertinent field measurements. • Results of laboratory analysis. • Assessment of mass of solvent removed. Reports will include data assessment and conclusions, as appropriate. CONFORMANCE WITH LAWS AND HEALTH AND SAFETY STANDARDS Remediation work done at the site shall be conducted in accordance with all applicable laws and regulations. All necessary permits for this work shall be obtained by SCS, Vernon Sanitation Supply Company, or their subcontractors in a timely manner. All persons performing work at the site shall adhere to appropriate health and safety standards, including necessary monitoring, to insure the protection of on-site workers and others, and off-site residents and workers. 5 B-8 SCS ENGINEERS— LIMITATIONS OF DATA All assumptions and estimates described herein are based on release estimates and limited environmental sampling and analysis. The assumptions in this document regarding the extent of environmental impacts, which may be subject to remedial action, and the scope of work which may be necessary to complete this action, are subject to change based on a number of factors. These factors include, but are not limited to, actual extent and nature of impacted material at the site, definition of impacted soils which may require remediation, requirements of the overseeing regulatory agencies, nature of specific soil transportation and/or treatment/recycling method chosen, health and safety and monitoring requirements, agency requirements for closure, and reporting requirements. 6 B-9 SCS ENGINEERS— REFERENCES Conservtech, April 1997,Subsurface Soils Investigation of Property Located at Alcoa and Packers Avenues, Vernon, California 90058.
