Wines Itl City of Bakersfield Fire Department ~ Environmental Services Division 1715 Chester Avenue, Suite 300 Bakersfield, CA 93301 .,, Subject: Work Plan for Conformation Sampling for the Saint Vincent De Paul Thrift Store Located at 300 Baker Street Bakersfield, California (APN 016-320-15-00-2) Dear Mr. Wines: GJL Environmental (GJL) is pleased to present this work Plan to collect conformation samples to insure the vapor extraction project is complete. SITE DESCRIPTION The Saint Vincent De Paul Thrift Store is located at 300 Bakers Street, Bakersfield, Kern County, California. The topography at the site is relatively flat, with a slight slope to the southwest. The subject site is bound on the east by Baker Street, on the south by Chico Street, and on the west and north by commercial properties. The Property is located at the southeastern quarter of the southwestern quarter of Section 29, T29S, R28E, MDBM, and is identified as APN 016-320~15-00-2. The property is situated within a developed commercial and light industrial area, interspersed with residential properties. A 550-gallon gasoline UST, dispenser, and associated product piping were previously removed from the site. SITE GEOLOGY According to the Geologic Map of California, Bakersfield Sheet, the site is situated over Quarternary fan deposits composed of sediment deposited by streams emerging from the highlands surrounding the valley. The test holes drilled during the site characterization study encountered fine-to-course-grained sand, sandy silt, and silt. 4009 Fairwood St. · Bakersfield, CA 93306-1310 Phone (805) 872-1543 · Fax (805) 872-2929 According to the Kern County Water Agency, Water Supply Report, 1999, the depth to the groundwater beneath the site was approximately 200 feet in the spring of 1999. No shallow perched groundwater is known to exist beneath the site. SITE STUDY Subsurface migration of contaminants appears to have been controlled by the influence of gravity and also by lithology. It is clear tl'iat the silt layer at a depth of approximately 25 feet has had a great deal of influence on the contaminant migration. Gasoline migrated relatively unimpeded through the sands above the silt and then spread latera!ly on top of the silt layer before penetrating to the sands below. It appears that the contamination tapers off below a depth of approximately 25 feet. The study ascertained the maximum vertical extent of the contaminant plume to be at a depth of approximately 53 feet and is located directly below the former tank location. The maximum extent of the contaminant plum is estimated to be a roughly circular zone approximately 47 feet in diameter between the depths of approximately 27 feet and 36 feet. The data indicates that the plume is slightly asymmetrical, but roughly circular in the horizontal cross section. It is estimated that the contaminant plume consists of roughly 1,500 cubic yards of soil. Based on the gasoline contaminants found in the soils below the former tank location, the Bakersfield Fire Department required remediation at the site. This sOil boring is to confirm that the on-site soil vapor extraction project is complete. SOIL SAMPLING PLAN One soil boring is proposed to assess the previous contaminant concentrations within the plume. The proposed boring location is shown on Figure 1. The test hole will be drilled through the middle of the contaminant plume to assess the current conditions within the plume. The boring will be drilled to a maximum depth of 55 feet. Soil samples will be collected at 10 foot intervals starting at a depth of 10 feet below the surface. The sample intervals may be modified slightly depending upon soil conditions; however, they should not deviate significantly from the proposed depths. Approximately 5 soil samples will be collected and field screened. Selected samples will be submitted for analyses. The soil samples will be analyzed for TPH gasoline and BTXE. The soil samples will be analyzed by BC Laboratories in Bakersfield. The quality assurance and quality control are available from the laboratory upon request. A chain of custody record documenting sample handling will be included. Soil samples will be collected using a split-spoon core sampler driven into the soil utilizing a truck-mounted hollow stem auger rig (Mobile Drill B-53). The split-spoon sampler holds three 2.5 inch diameter by 6 inch long brass liners. The core sampler will be driven through the proper sampling interval after the hole is drilled to the sample depth with the hollow stem auger. The sample will then be removed from the drilling equipment and the brass liners removed from the sampler. The ends of the bottom liner from each sample depth will be covered with Teflon seals and polyethylene caps. The liner will then be labeled and placed in a polyethylene sample bag and the bag sealed and labeled. Each bagged liner will be plaCed on blue ice and retained in a chilled state for delivery to the laboratory. Another soil sample from each sample depth will be retained for field screening and soil description. Field screening will'consist of a headspace reading for hYdrocarbon vapors with an Hnu PID meter. In addition to the headspace readings, hydrocarbon odors, if present, will be noted. The sampling equipment will be scrubbed, washed, and thoroughly rinsed between each sample collection. The test hole will be backfilled with bentonite chips. Contaminated drill cuttings, as identified by field screening, will be placed in DOT drums and retained on-site for future treatment or disposal by the client. The results of the field investigation will be presented in a formal report which will include a. boring log, laboratory report and conclusions. SITE SAFETY PLAN The Site Safety Plan is included as Appendix A. Submitted by: Gary J. Leary Registered Environmental Assessor State of California #00003 APPENDIX A SITE SAFETY PLAN SITE SAFETY PLAN The responsible party for the work will be GJL Environmental personnel. The expected hazardous material at the site is gasoline, which will be blended with soil. The purpose of this plan is to eStablish procedures to protect all on-site personnel from direct skin contact, inhalation; or ingestion of potentially hazardous materials that may be encountered at thC'site. GJL Environmental plans on drilling one soil b°i:ing through the former underground tank location. The boring will be drilled by: Melton Drilling Company 1701 Downing Avenue Bakersfield, California 93306 C-57 license number 508270. Gary J. Leary, Registered Environmental Assessor, will serve as project manager, field technician, and site safety officer. Gary J. Leary will assure that all on-site .personnel have a copy of the site safety plan. Compliance with the site safety plan will be m'onitored at all times. A training session will be conducted to assure that all personnel are aware of safe work practices. Gary J. Leary will be responsible for keeping field notes, collecting soil samples, and following chain-of-custody protocol. On-site employees will take reasonable precautions to avoid unforeseen hazards. On-site employees are to adhere strictly to the provision of this safety plan. The drilling contractor has been employed to deliver and operate all drilling equipment. Only qualified personnel will have contact with this equipment. All on-site personnel are required to wear hard hats when near the drilling rig. Proper respiratory equipment will be worn if vapor levets exceed action levels. An action level of 5 ppm in the breathing zone will require respiratory proteCtion. During all operations that might release airborne vapors, an Hnu PID meter will be used to monitor vapors in the breathing zone of workers. If there are significantly higher readings than 5 ppm for a sustained period, the drilling and/or soil sampling operations. will be suspended and the work reevaluated. No smoking will be permitted at the work site. COntaminated drill cuttings, as identified by field screening, will be continuously placed in DOT drums and covered. On-site personnel will be exposed only to gasoline contaminated soil. This can present'a significant hazard. Volatile organic compounds can be significant in soil contaminated with gasOline. RecognitiOn of hazards, whether it be from instrument readings, odor, irritation, visibility, headache, dizziness, or fatigue, is important, .bUt it is equally important to take appropriate action when a hazard is recognized. If the problem cannot be promptly corrected, we will back off from the exposure source and obtain assistance to solve the Problem. Work practices and engineering contrOls will be devised to minimize potential exposures. For example, where possible, we will work upwind of any potential exposure source. Air-purifying respirators with combination organic vapodacid, gas/dust, fume, and mist · cartridges will be on location. Replacement cartridges will be available as necessary. These will be worn when PID readings persist above 5 ppm in the breathing zone. If there is eye irritation, full-face respirators will be used. Tryvek coveralls will be worn as necessary to avoid skin contact with contaminated soils. Chemical resistant gloves and boots will also be worn as necessary to avoid hand and foot contact with contaminants. Ear protection, as appropriate, will also be worn. All personnel will be advised that any portions of their bodies, which might have contacted possible contaminants, should be washed with soap and water before taking a break or leaving the site. Respirators, if used, will also be decontaminated at the end of the work day. Supervisory personnel involved in drilling and sample retrieval have received training as specified in the OSHA Hazardous Waste Operations and Emergency Response Standard (29CRF1910.120). The physical hazards associated with operating a drilling rig and sampling equipment must be recognized. Individuals not directly involved in drilling shall stand back at least the distance of the vertical boom. A restricted area will be established around the work area as needed. The potential hazards involved in this job will be reviewed with all personnel, including subcontractors, working on-site. Prior to commencement of work, emergency evacuation routes will be established. A "safe zone" location will be established taking into account weather conditions, site activities and other factors as necessary. Access to the site will be restricted to authorized personnel. Gary J. Leary will be responsible for site secUrity. According to 29CFR1910.120, paragraph (f), employees who wear respirators 30 days or more during one year or who have been exposed to hazardous substances or health hazards above established permissible exposure limits are required to be monitored medically. All site . .'personnel subject to these conditions are required to have a complete chemical physical on an annual basis. 'Documentation will be kept on personnel exposed to contaminant hazards on the job site .~according to OSHA regulations. These will include documentation that employees have received training on the site safety plan, respiratory protection, and all emergency procedures. Exposure records will be kept in the job file. These will include name and social security number of employees, job entry log, and first aid administered. 'Arrangements Will be made for transportation to a hospital in the event of an accident or exposure to hazardous materials that produce organic symptoms in the exposed party. In the event of accident,injury, or other emergency, notification will be as follows: 1.

The subject!s!te is'bound on the east by Baker Street, on the south by Chico Street, and on the westand north by commercial properties. The property is located at the southeastern quarter of thb:"~o'uthWestern quarter, of Section 29, T29S, R28E, MDBM, and is identified as APN 01.6-:~20-15-00-2. The property is situated within a developed commercial and light industrial area, interspersed with residential properties. A 550-gallon gasoline UST, dispenser, and associated product piping were previously removed from the site. SITE GEOLOGY According to the Geologic Map of California, Bakersfield Sheet, the site is situated over Quarternary fan deposits composed of sediment deposited by streams emerging from the highlands surrounding the valley. The test holes drilled during the site chara, cterization study encountered fine-to-course-grained sand, sandy silt, and silt. 4009 Fairw0od St. · Bakersfield, CA 93306-1310 Phone (805) 872-1543 · Fax (805) 872-2929 According to the Kern County Water Agency, Water SuPply Report, 1999, the depth to the groundwater beneath the site was approximately 200 feet in the spring of 199.9. No shallOw perched groundwater is known to exist beneath the site. SITE STUDY Subsurface migration of contaminants appears to have been controlled by the influence of gravity and also by lithology. It is clear that the silt layer at a depth of approximately 25 feet has had a great deal of influence on the contaminant migration. Gasoline migrated relatively unimpeded through the sands above the silt and then spread laterally on top of the silt layer before penetrating to the sands below. It appears that the contamination tapers off below a depth of approximately 25 feet. The study ascertained the maximum vertical extent of the contaminant plume to be at a depth of approximately 53 feet and is located directly below the former tank location. The maximum extent of the contaminant plum is estimated to be a roughly circular zone approximately 47 feet in diameter between the depths of approximately 27 feet and 36 feet. The data indicates that the plume is slightly asymmetrical, but roughly circular in the horizontal cross section. It is estimated that the contaminant plume consists of roughly 1,500 cubic yards of soil. Based on the gasoline contaminants found in the soils below the former tank location, the Bakersfield Fire Department required remediation at the site. This sOil boring is to confirm that the on-Site soil vapor extraction project is complete. SOIL SAMPLING PLAN One soil boring is proposed to assess the previous contaminant concentrations within the plume. The proposed boring location is shown on Figure 1. The test hole will be drilled through the middle of the contaminant plume to assess the current conditions within the plume. The boring will be drilled to a maximum depth of 55 feet. Soil samples will be collected at 10 foot intervals starting at a depth of 10 feet below the surface. The sample intervals may be modified slightly depending upon soil conditions; however, they should not deviate significantly from the proposed depths. Approximately 5 soil samples will be collected and field screened. Selected samples will be submitted for analyses. The soil samples will be analyzed for TPH gasoline and BTXE. The soil samples will be analyzed by BC Laboratories in Bakersfield. The quality assurance and quality control are available from the laboratory upon request. A chain of custody record documenting sample handling will be included. Soil samples will be collected using a split-spoon core sampler driven into the Soil utilizing a truck-mounted hollow stem auger rig (Mobile Drill B-53). The split-spoon sampler holds three 2.5 inch diameter by 6 inch long brass liners. The core sampie~-will be;,dr, iven through :the_proper sampling interval after the. hole is drilled to the sample depth.With the hollow, stem auger. The sample will then be removed from the drilling equipment, and the brass liners removed from the sampler. The ends of the bottom liner from each sample depth will be covered with Teflon seals and 'p~)lyethylene capS. The liner will then be labeled and placed in a polyethylene sample bag and the--bag 'Sealed.and-labeled. Each bagged liner will be placed on blue 'ice and retained in a chilled state f~r delivery to the laboratory. Another soil sample from each sample depth will be retained for field screening and soil description. Field screening will'consist of a headspace reading for hYdrocarbon vapors with an Hnu PID meter. In addition to the headspace readings, hydrocarbon odors, if present, will be noted. The sampling equipment will be scrubbed, washed, and thoroughlY rinsed between each sample collecti0-n. The test hole will be backfilled with bentonite chips. Contaminated drill cuttings, as identified by field screening, will be placed in DOT drums.and retained on-site for future treatment or disposal by the client. The results of the field investigation will be presented in a formal report which will include a boring Icg, laboratory report and conclusions. SITE SAFETY PLAN The Site Safety Plan is included ::as-Appendix A. Submitted by: Gary J. Leary Registered Environmental Assessor State of California #00003 APPENDIX A SITE SAFETY PLAN SITE SAFETY PLAN The responsible party for the work will be GJL Environmental personnel. The expected hazardous material at the site is gasoline, which will be blended with soil. The purpose of this plan is to eStablish procedures to protect all on-site personnel from direct skin contact, inhalation, or ingestion of potentially hazardous materials that may be encountered at the site. GJL Environmental plans on drilling one soil boring through the former underground tank location. The boring will be drilled by: Melton Drilling Company 1701 Downing Avenue Bakersfield, California 93306 ' C-57 license number 508270. Gary J. Leary, Registered Environmental Assessor, will serve as project manager, field technician, and site safety officer. Gary J. Leary will asSure that all on-site personnel have a copy of the site safety plan. Compliance with the site safety plan will be m'onitOred at all times. A training session will be conducted to assure that all personnel are aware of safe work practices. Gary J. Leary will be responsible for keeping field notes, collecting soil samples, and following chain-of-custody protocol. On-site employees will take reasonable precautions to avoid unforeseen hazards. On-site emploYees are to adhere strictly to the provision of this safety plan. The drilling contractor has been employed to deliver and operate all drilling equipment. Qnly qualified personnel will have contact with this equipment. All on-site personnel are required to wear hard hats when near the drilling rig. Proper respiratory equipment will be worn if vapor levels exceed action levels. An action level of 5 ppm in the breathing zone will require respiratory protection. During all operations that might release airborne vapors, an Hnu PID meter will be used to monitor vapors in the breathing zone of workers. If there are significantly higher readings than 5 ppm for a sustained period, the drilling and/or soil sampling operations 'will be suspended and the work reevaluated. No smoking will be permitted at the work site. Contaminated drill cuttings, as identified by field screening, will be continuously placed in DOT drums and covered. On-site personnel will be exposed only to gasoline contaminated soil. This can present'~a significant hazard. Volatile organic compounds can be significant in soil contaminated with gasoline. Recognition of hazards, whether it be from instrument readings, odor, irritation, visibility, headache, dizziness, or fatigue, is important, bUt it is equally important to take appropriate action when a hazard is recognized. If the problem cannot be promptly corrected, we will back off from the exposure source and obtain assistance to solve the Problem. Work practices and engineering ContrOls will be devised to minimize potential exposures. For example, where possible, we will work upwind of any potential exposure source. Air-purifying respirators with combination organic vapor/acid, gas/dust, fume, and mist cartridges will be on location. Replacement cartridges will be available as necessary. TheSe will be worn when PID readings persist above 5 ppm in the breathing zone. If there is eye irritation, full-face respirators will be used. Tryvek coveralls will be worn as necessary to avoid skin contact with contaminated soils. Chemical resistant gloves and boots will also be worn as necessary to avoid hand and foot contact with contaminants. Ear protection, as appropriate, will also be worn. All personnel will be advised that any portions of their bodies, which might have contacted possible contaminants, should be washed with soap and water before taking a break or leaving the site. Respirators, if used, will also be decontaminated at the end of the work day. Supervisory. personnel involved in drilling and sample retrieval have received training as specified in the OSHA Hazardous Waste Operations and Emergency Response Standard (29CRF1910.120). The physical hazards associated with operating a drilling rig and sampling equipment must be recognized. Individuals not directly involved in drilling shall stand back at least the distance of the vertical boom. A restricted area will be established around the work area as needed. The potential hazards involved in this job will be reviewed with all personnel, including subcontractors, working on-site. Prior to commencement of work, emergency evacuation routes will be established. A "safe zone" location will be established taking into account weather conditions, site activities and other factors as necessary. Access to the site will be restricted to authorized personnel. Gary J. Leary will be responsible for site security. According to 29CFR1910.120, paragraph (f), employees who wear respirators 30 days or more during one year or who have been exposed to hazardous substances or health hazards above established permissible exposure limits are required to be monitored medically. All site .... personnel subject to these conditions are required to have a complete chemical physical on an annual basis. · 'Documentation will be kept on' personnel exposed to contaminant hazards on the job site ~according to OSHA regulations. These will include documentation that employees have received training on the site safety plan, respiratory protection, and all emergency procedures. Exposure records will be kept in the job file. These will include name and social security number of employees, job entry log, and first aid administered. Arrangements will be made for transportation to a hospital in the event of an accident or exposure to hazardous materials that produce organic symptoms in the exposed party. In the event of accident, injury, or other emergency, notification will be as follows: 1.

JERVICES SubjeCt: FOURTH QUARTER 2000 PROGRESS REPORT FOR THE i- ~ SAINT VINCENT DE 'PAUL THRIFT STORE LOCATED AT 300 BAKER STREET, BAKERSFIELD~ CALIFORNIA (APN 016-320-15-00-2) Dear Mr. Wines: Holguin, Fahan & Associates, Inc. (HFA) is pleased to present this Fourth Quarter 2000 Progress Report of the ongoing remedial action being conducted in association with the former UST at the above-referenced property. During the first quarter of 1999, Saint Vincent De Paul obtained pre-approval of costs for active remediation from the State Water Resources Control Board/Underground Storage Tank Cleanup Fund (SWRCB/USTCF). During the second quarter Of 1999, the San Joaquin Valley Unified Air Pollution Control District - Southern Region (SJVUAPCD-SR) issued ATC Peimit ~S-3548-1-0 for the installation and operation of the VES at the site. During the second quarter of 1999, the seven VES wells were also constructed. During the third quarter of 1999, the VES unit was delivered to the site and connected to electricity and supplemental fuel as well as the vapor extraction wells, and start-up system testing was performed. During the fourth quarter of 1999, full-time operation of the VES was initiated and continued thro,ugh the end of the first quarter of 2000, when the unit was shut down pending City of Bakersfield Fire Department Environmental Services Division (BFDESD) site status review and determination as to whether additional active remediation is warranted or progress soil sampling should be conducted to determine the residual concentration of gasoline hydrocarbons in the subsurface. The BFDESD, in its letter dated June 9, 2000, determined that an additional 3 months of operation of the VES is warranted. Because of delays in the reimbursement of costs by the SWRCB/USTCF for the remediation activities, the public utilities :had itempo~'arily terminated service to the unit. Upon receiving reimbursement from the SWRCB/USTCF, and paying the back utility bills, the electricity and natural gas services were reinstated: However, service was not restored until after the end of the second quarter of 2000. Therefore, the VES unit was not restarted until the third quarter of 2000.

However, due to the diminished moss of hydrocarbon extracted during December of 2000, the VES unit was shut down at the end of the fourth quarter of 2000, pending the BFDESD site status review and determination os to whether additional active remediafion is warranted or progress soil sampling should be conducted to determine the residual concentration of gasoline hydrocarbons in the subsurface. SITE DESCRIPTION The Saint Vincent De Paul Thrift Store is located at 300 Baker Street, Bakersfield, Kern County, California. The topography at the site is relatively flat, with a slight slope to the southwest (see Figure 1 ~ Site Location Map). The subject site is bound on the east by Baker Street, on the south by Chico Street, and on the west and north by commercial properties. The property is located in the southeastern quarter of the southwestern quarter of Section 29, T29S, R28E, MDBM and is identified as APN 016-320-15-00-2. The property is situated within a developed commercial and light industrial area, interspersed with residential properties. A 550-gallon gasoline UST, dispenser, and associated product piping were previously removed from the site (see Figure 2 - Plot Plan Showing VES). The property owner is Saint Vincent De Paul.

BACKGROUND GEOLOGY The site is located in a relatively flat area at an elevation of approximately 415 feet above MSL. The site is located in the southern portion of the Great Valley geomorphic province. The Great Valley is a north-south-trending valley, approximately 400 miles long by EO miles wide, the southern portion of which is known as the San Joaquin Valley. The surface of the San Joaquin Valley is composed primarily of unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Mio-Pliocene marine sediments, which extend to a crystalline basement at a depth of HOLGUIN, Mr. Howard H. Wines, tll BFDESD ~ FAI-~ February 1,2001- Page 3 ~ & ASSOCIATF_.S, 1NC. ENVIRONMENTAL MANAGEMENT CONSULTANTS approximately 30,000 fbg, Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest, The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Division of Mines and Geology, 1965, Geologic Map of California, Bakersfield Sheet). The site is an area at the foot of rolling hills reaching a maximum elevation of gOO feet above MSL, located on the eastern flank of the San Joaquin Valley and west of the southern Sierra Nevada. The Kern River drains a large area of the southern Sierra Nevada, including the highest part of the range at Mount Whitney. The modern river has cut a channel southeast of the site and provides recharge for groundwater along its course. Sedimentary geologic formations, observed at the surface and underlying the site were sourced by the Sierra Nevada and transported via the ancestral Kern River. in the region of the site, the Tertiary sedimentary sequence from top to bottom is nonmarine Kern River Formation, nonmarine Chanac Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to the tentative correlation of type Santa Margarita Formation west of the San Andreas Fault), marine Round Mountain Silt, marine Oicese Sand,' marine Freeman Silt, marine Jewett Sand and Pyramid Hill member, marine Vedder Sand, nonmarine Walker Formation. Of these, only the Kern River, Chanac, and Santa Margarita formations are important to the hydrogeology of the site. The Tertiary, nonmarine Kern River Formation is unconformably overlain by bouldery terrace deposits of Quaternary Older Alluvium. Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the Tertiary (Miocene to Pliocene), nonmarine Kern River Formation and the Quaternary (Pleistocene) Older Alluvium. The Older Alluvium forms a thin terrace deposit lying unconformably on the Kern River Formation. Quaternary Older Alluvium: The middle to lower Pleistocene (Bartow, J.A., 1984, Geologic Map and Cross Sections of the Southeastern San Joaquin Valley, California, USGS Map 1-1496), Older Alluvium is a flat-lying terrace deposit approximately 5 to 10 feet thick that overlies the erosional surface of the Kern River Formation. The Older Alluvium is composed of very coarse material, with boulders as large as 50 cm in diameter. Clastic material composition includes granitic and dioritic, crystalline rocks characteristic of the Sierra Nevada batholiths, quartzite characteristic of pre-batholithic rocks, and volcanic and related rocks such as andesite and dark siliceous agate typical of the Neogene deposits of the Mojave Desert. In some locations, caliche rims have developed between clasts. .~~ } HOLGUIN, Mr. Howard H. Wines, III BFDESD FAHAN February 1,2001- Page 4 & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS Kern River Formation: The age of the Kern River Formation includes upper Miocene and Pliocene and possibly Pleistocene deposits. The Kern River Formation is composed of interstratified fanglomeratic deposits and silty claystones. Within the fanglomerates are conglomerate beds with cobbles as large as 20 cm in diameter, and in some areas fanglomerate beds exhibit cross bedding from 2.5 to 5 meters thick. The silty claystone beds, which would serve as Iow-permeability barriers to vertical migration, are laterally continuous to as much as several thousand feet, but are locally truncated by sandy fanglomerate units. Another important factor in considering the potential for migration is the lack of secondary permeability within the Kern River Formation as no secondary cracks, small faults, or gypsum veins are observed. Chanac Formation: The Chanac Formation of upper Miocene age is not exposed on or near the site, but outcrops in the cliffs southeast of the site along the Kern River bluffs at Hart Park. It is a thinly bedded, chalky siltstone exhibiting many secondary cracks and gypsum veins. On-site soil borings indicate that the alluvium is characterized by highly permeable, fine-grained to coarse-grained sands interbedded with lower permeability, silt zones ranging in depth from 24 to 27 fbg, 35 to 37 fbg, 44 to 57 fbg, and 63 to 70 fbg. The base of gasoline-containing soils is within the silty interval ranging in depth from 44 to 57 fbg. HYDROGEOLOGY Surface water and groundwater in the San Joaquin Valley are derived predominantly from the Sierra Nevada to the east, and are transported by five major rivers, the southernmost being the Kern River. The subject site is located approximately 2 miles south of the Kern River. The depth to the regional unconfined aquifer mapped by the Kern County Water Agency (KCWA) is approximately 200 fbg at the site, with the direction of groundwater flow to the southwest (KCWA, 1998, 1997 Report on Water Conditions, February 1, 1998). The nearest known occurrence of perched groundwater is 2 miles to the southwest at a depth of 20 fbg in the abandoned Kern River channel to the ancient Kern Lake bed (KCWA, 1998, 1995 Water Supply Report, January 1998). PREVIOUS WORK Based on a review of available data, analytical results, and conversations with Mr. Smith, on June 17, 1991, a 550-gallon gasoline UST, dispenser, and associated product piping were removed from the property. Laboratory analytical results of soil samples collected from beneath the location of the UST indicated concentrations of gasoline hydrocarbons. ©n January 28, 1992, Smith-Gutcher advanced four soil borings (TH-1 through TH-4) to a maximum depth of 70 fbg in and around the area of the former UST, Laboratory analysis of soil HOLGUIN, Mr. Howard H, Wines, III BFDESD FAHAN February 1,2001- Page 5 ~ & ASSOCIATE. S, INC. ENVIRONMENTAL MANAGEMENT CONE~ULTANTS samples collected from the soil borings indicated gasoline-containing soil to a depth of approximately 55 fbg within an approximate 25-foot radius around the former UST at the site (see Attachment 1 for a summary of previous work). Gasoline-containing soils are believed to extend to at least 20 feet beneath the southwestern corner of the thrift store building. Groundwater was not encountered and is not anticipated above a depth in excess of 200 fbg. The known contaminant at the site has been identified as petroleum hydrocarbons in the gasoline range. The total volume of hydrocarbon-containing soils was estimated to be 3,650 culSic yards, containing an estimated 2/120 pounds of hydrocarbons in the gasoline range. This equates to approximately 3~;0 gallons of gasoline absorbed into the subsurface. Approximately 485 pounds of the hydrocarbons is estimated to be present beneath the thrift store building. HFA prepared a CAP dated June 17, 1996, for the site. A risk evaluation of the gasoline-containing soils at the site was conducted using American Society for Testing and Materials Designation: E-1739 Risk-Based Corrective Action Applied at Petroleum Release Sites (RBCA). The results of RBCA Tier 1 and 2 evaluations were that the indoor air inhalation pathway exceeds the permissible lifetime lx10.6 exposure levels given the concentration of benzene in the soils beneath the thrift store building and that mitigation is required to reduce these concentrations to a permissible residual level, which is protective of the health of the occupants of the building. An RI/FS was conducted to assess the feasibility and cost effectiveness of mitigation technologies. The RI/FS analysis concluded that in-situ vapor extraction is the cost-effective mitigative alternative, which is protective of the health of the current occupants of the building. The BFDESD, in its case review letter dated July 30, 1996, concurred with the conclusions of the RI/FS and requested initiation of in-sifu vapor extraction. Said Vincent De Paul obtained competitive bids to Implement the CAP and submitted these bids to the SWRCB/USTCF for pre-approval of costs. The SWRCB/USTCF, in ifs lelter dated June 4, 1997, denied pre-approval of costs to conduct active soil remediQtion and requested additional soil investigation to determine whether concentrations of gasoline hydrocarbons in the soils presented a health risk to the occupants of the building. On september 16, 1997, Smith-Gutcher advanced soil boring TH1 through the location of the former UST to a depth of 45 fbg. Gasoline hydrocarbon concentrations were detected in the soil samples collected from depths of 15, 20, 30, and 45 fbg (see Attachment 1). Given the results of the soils investigation, significant concentrations of gasoline hydrocarbons remained HOLGUIN, Mr. Howard H. Wines, III BFDESD ~ FA~ February 1 2001- Page6 ~ , ~ & ASSOCIATF_.S, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS in the soils in and around the former UST, including beneath the southwestern corner of the thrift store building. Upon review of the laboratory analytical results, the SWRCB/USTCF requested that a soil vapor assessment be conducted to determine if gasoline hydrocarbon vapors were present in the near-surface soils, which would present a risk of exposure to the occupants of the building. On May 6, 1998, HFA collected soil vapor samples (G-1 through G-4) around the periphery of the foundation to assess whether gasoline hydrocarbons may be migrating into the thrift store building. HFA advanced an AMSTM soil gas vapor probe to a depth of 3 fbg at each location. Gasoline hydrocarbon concentrations were detected in soil vapor samples G-1 through G-4. However, TPH as gasoline and benzene concentrations were not detected in soil vapor samples G-1 through G-4 (see Attachment 1). Given the results of the soil vapor survey, the BFDESD, in its letter dated July 28, 1998, required 3 months of operation of the VES to reduce the potential migration of gasoline hydrocarbons into the thrift store building prior to considering the site for closure. During the first quaffer of 1999, Saint Vincent De Paul obtained pre-approval of costs for active remediation from the SWRCB/USTCF. During the second quarter of 1999, SJVUAPCD-SR ATC Permit #S-3548-1-0 was obtained for the installation and operation of a VES at the site, and subsequently, seven vapor extraction wells (VW-1 through VW-7) were constructed. Duringthe third quarter of 1999, the VES unit was delivered to the site and connected to electricity and supplemental fuel as well as the vapor extraction wells, and start-up system testing was performed (see Figure 3- VES Schematic Diagram and Figure 4 - VES Process Component Description). On October 1t, 1999, HFA began full-time operation of the VES, and the SJVUAPCD-SR conducted an inspection of the system on December 21, 1999. The SJVUAPCD-SR observed that the equipment was identical to that contained in the original permit, and the operating parameters were in compliance with the conditions of the ATC permit. On December 21, 1999, January 28, 2000, February 29, 2000, and March 15, 2000, HFA performed vapor sampling of the influent and effluent streams of the thermal oxidizer. TPH as gasoline was detected in the influent vapor samples at concentrations of 371, 1,760, 659, and 1,190 ppmv for the December 21, 1999, January 28, 2000, February 29, 2:g~, and March 15, 2000, sampling events, respectively, and was not detected in the effluent samples (see Figure 5- Influent and Effluent TPH Concentrations, Table 1-Summary of Source Compliance Monitoring Analytical Results, and Table 2- Summary of VES Monitoring Data). HFA estimates the mass of gasoline hydrocarbons extracted from the subsurface since start-up to be approximately 5,383 pounds, '" HOLGUIN, Mr. Howard H. Wines, Ill BFDESD ~ FA~ February 1,2001- Page 7 ~ & ASSOCIATF_.S, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS which is equivalent to approximately 841 gallons of gasoline [see Figure 6 - Cumulative Extraction Curve and Table 2). At the end of the first quarter of 2000, the unit was shut down pending BFDESD site status review and determination whether additional active remediation is warranted or progress soil sampling should be conducted to determine the residual concentrations of gasoline hydrocarbons in the subsurface. The BFDESD, in its letter dated June 9, 2000, determined that an additional 3 months of operation of the VES is warranted. Because of delays in the reimbursement of costs by the SWRCB/USTCF for the remediation activities, the public utilities had temporarily terminated service to the unit. Upon receiving reimbursement from the SWRCB/USTCF, and paying the back utility bills, the electricity and natural gas services were reinstated. However, service was not restored until after the end of the second quarter of 2000. Therefore, the VES unit was not restarted until the third quarter of 2000. REMEDIAL ACTION REPORT FOR THE FIRST QUARTER OF 2000 HFA has operated the VES unit 24 hours per day since start-up, with only short periods of inactivity for maintenance, draining of the knockout pot, and a few occurrences when the system was shut down. Inlet vapor concentrations ranged from 615 to 10 ppmv during the fourth quarter of 2000 (see Figure 5 - Influent and Effluent TPH Concentrations and Table 2 - Summary of VES Monitoring Data). On October 31, 2000 and November 30, 2000 HFA performed vapor sampling of the influent and effluent streams of the thermal oxidizer. TPH as gasoline was detected in the influent vapor sample at concentrations of 432 and 29.1 ppmv for the October 31, 2000 and November 30, 2000, sampling events, respectively, (see Table 1 and Attachment 2 for the laboratory reports). The inlet soil vapor flow rate has been maintained near the maximum stated in the ATC permit and consistently ranges from 160 to 230 scfm. HFA estimates the mass of gasoline hydrocarbons extracted from the subsurface since start-up to be approximately 8,169 pounds, which is equivalent to approximately 1,276 gallons of gasoline. However, due to the diminished concentrations of the hydrocarbons extracted, only 22 pounds were extracted during December of 2000 (see Figure 6 - Cumulative Extraction Curve and Table 2). Because of the small mass of hydrocarbons extracted during December of 20~, the unit was shut down at the end of the fourth quarter of 2000, pending BFDESD site status review and determination whether additional active remediation is warranted or progress soil sampling should be conducted to determine the residual concentrations of gasoline hydrocarbons in '~ HOLGUIN, Mr. Howard H.

If the BFDESD determines that a remediation soil assessment be performed, then HFA will provide the BFDESD with a work plan to perform the requested soil assessment. ACTIVITIES PLANNED FOR THE FIRST QUARTER OF 2001 During the first quarter of 2001, full-time operation of the VES will be reinitiated in accordance with the conditions of the ATC permit, if requested by the BFDESD, Otherwise, remediation progress soil sampling will be performed upon approval by the BFDESD of a soil sampling work plan.

(HFA) is pleased to present this Third Quarter 2000 Progress Report of the ongoing remedial action being conducted in association with the former UST at th:e above-referenced property. During the first quarter of 1999, Saint Vincent De Paul obtained pre-approval of costs for active remediation from the State Water Resources Control Board/~Underground Storage Tank Cleanup Fund (SWRCB/USTCF). During the second quarter of 1999, the San Joaquin Valley Unified Air Pollution Control District Southern Region (SJVUAPCD-SR) issued ATC Permit #S-3548- !-0 for the installation and operation of the iVES at the site. During the secon'd quarter of 1999, the seven VES wells Were also constructed. During the third quarter of 1999, the VES unit was delivered to the site and connected to electrici~/ and supplemental fuel' as well as the vapor extraction wells, and start-up system testing was performed. D~Jring the fourth quarter of 1999, full-time operation of the VES was initiated and continued through the end of the first quarter of 2000, when :the unit was shut down pending City of Bakersfield Fire Department Environmental Services Division (BFDESD) site status review and determination as to whether additional aclive remediation is warranted or progress soil sampling should be conducted to determine the residual concentration of gasoline hydrocarbons in the subsurface. The BFDESD, in its letter dated June 9, 2000, determined that an additional 3 months of operation of the VES is warranted. Because of delays in the reimbUrsement of costs by the SWRCB/USTCF for the remediation activities, the public utilities had temporarily terminated service to the unit. Upon receiving reimbursement from the sWRCB/USTCF, and paying the back utility bills, the electricity and natural gas services were reinstated. However, service was not restored until after the end of the second quarter of 2000. Therefore, the VES Unit was not restarted unti! the ~hird quarter of 2000.

ENVIRONMENTAL MANAGEMENT CONSULTANTS SITE DESCRIPTION The Saint Vincent De Paul Thrift Store is located at 300 Baker Street, Bakersfield, Kern County, California. The topography at the site is relatively flat, with a slight slope to the southwest (see Figure 1 - Site Location Map). The subject site is bound on the east by Baker Street, on the south, by Chico Street, and on the west and north by commercial properties. The property is located in the southeastern quarter of the southwestern quarter of Section 29, T29S, R28E, MDBM and is identified as APN 016-32[]-t5-0G2. The property is situated within a developed commercial and light industrial area, interspersed with residential properties. A 550-gallon gasoline UST, dispenser, and associated product piping were previously removed from the site (see Figure 2 - Plot Plan Showing VES). The proPerty owner is Saint Vincent De Paul. The owner contact is Father Ralph Belluomini, 310 Baker Street, Bakersfield, California, 93305, (661) 323-7340. The project consultant contact is Mr. Duane R. Smith, Smith-Gutcher & Associates, Inc.

BACKGROUND GEOLOGY The site is located in a relatively flat area at an elevation of approximately 415 feet above MSL. The site is located in the southern portion of the Great Valley geomorphic province. The Great Valley is a north-south-trending valley, approximately 400 miles long by 50 miles wide, the southern portion of which is known as the San Joaquin Valley. The surface of the San Joaquin Valley is composed primarily of unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Mio-Pliocene marine sediments, which extend to a crystalline basement at a depth of approximately 30,000 fbg. Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Division of Mines and Geology, 1965, Geologic Map of California, Bakersfield Sheet). The site is an area at the foot of rolling hills reaching a maximum elevation of gE][] feet above MSL, located on the eastern flank of the San Joaquin Valley and west of the southern '~~1 HOLGUIN, Mr. Howard H. Wines, III BFDESD FAHAN January 25,200~- Page 3 & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANT~ Sierra Nevada. The Kern River drains a large area of the southern Sierra Nevada, including the highest part of the range at Mount Whitney. The modern river has cut a channel southeast of the site and provides recharge for groundwater along its course. Sedimentary geologic formations, observed at the surface and underlying the site were sourced by the Sierra Nevada and transported via the ancestral Kern River. In the region of the site, the Tertiary sedimentary sequence from top to bottom is nonmarine Kern River Formation, nonmarine Chanac Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to the tentative correlation of type Santa :Margarita Formation west of the San Andreas Fault), marine Round Mountain Silt, marine Olcese Sand, marine Freeman Silt, marine Jewett Sand and Pyramid Hill member, marine Vedder Sand, nonmarine Walker Formation. Of these, only the Kern River, Chanac, and Santa Margarita formations are important to the hydrogeology of the site. The Tertiary, nonmarine Kern River Formation is unconformably overlain by bouldery terrace deposits of Quaternary Older Alluvium. Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the Tertiary (Miocene to Pliocene), nonmarine Kern River Formation and the Quaternary (Pleistocene) Older Alluvium. The Older Alluvium forms a thin terrace deposit lying unconformably on the Kern River Formation. Quaternary Older Alluvium: The middle to lower Pleistocene (Bartow, J.A., 1984, Geologic Map and Cross Sections of the Southeastern San Joaquin Vdtey, California, USGS Map 1-1496), Older Alluvium is a flat-lying terrace deposit approximately 5 to 10 feet thick that overlies the erosional surface of the Kern River Formation. The Older Alluvium is composed of very coarse material, with boulders as large as 50 cm in diameter. Clastic material composition includes granitic and diofitic, crystalline rocks characteristic of the Sierra Nevada batholiths, quartzite characteristic of pre-bathoiithic rocks, and volcanic and related rocks such as andesite and dark siliceous agate typical of the Neogene deposits of the Mojave Desert, In some locations, caliche rims have developed between clasts. / Kern River Fermotioq: The age of the Kern River Formation includes upper Miocene and Pliocene and possibly Pleistocene deposits. The Kern River Formation is composed of interstratified fanglomeratic deposits and silty claystones. Within the fanglomerates are conglomerate beds with cobbles as large as 20 cm in diameter, and in some areas fanglomerate beds exhibit cross bedding from 2.5 to 5 meters thick. The silty claystone beds, which would serve as Iow-permeability barriers to vertical migration, are laterally continuous to as much as several thousand feet, but are locally truncated by sandy fanglomerate units. Mr. Howard H. Wines, Ill ~__~ HOLGUIN, BFDESD ~ FA~ January 25, 2001- Page 4 ~ & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS Another important factor in considering the potential for migration is the lack of secondary permeability within the Kern River Formation as no secondary cracks, small faults, or gypsum veins are observed. chana¢ Formation: The Chanac Formation of upper Miocene age is not exposed on or near the site, but outcrops in the cliffs southeast of the site along the Kern River bluffs at Hart Park. It is a thinly bedded, chalky siltstone exhibiting many secondary cracks and gypsum veins. 'On-site soil borings indicate that the alluvium is characterized by highly permeable, fine-grained to coarse-grained sands interbedded with lower permeability, silt zones ranging in depth from 24 to 27 fbg, 35 to 37 fbg, 44 to 57 fbg, and 63 to 70 fbg. The base of gasoline-containing soils is within the silty interval ranging in depth from 44 to 57 fbg. HYDROGEOLOGY Surface water and groundwater in the San Joaquin Valley are derived predominantly from the' Sierra Nevada to the east, and are transported by five major rivers, the southernmost being the Kern River. The subject site is located approximately 2 miles south of the Kern River. The depth to the regional unconfined aquifer mapped by the Kern County Water Agency (KCWA) is approximately 200 fbg at the site, with the direction of groundwater flow to the southwest (KCWA, 1998, 1997 Report on Water Conditions, February 1, 1998). The nearest known occurrence of perched groundwater is 2 miles to the southwest at a depth of 20 fbg in the abandoned Kern River channel to the ancient Kern Lake bed (KCWA, 1998, 1995 Water Supply Report, January 1998). PREVIOUS WORK Based on a review of available data, analytical results, and conversations with Mr. Smith, on June 17, 1991, a 550-gallon gasoline UST, dispenser, and associated product piping were removed from the property. Laboratory analytical results of soil samples collected from beneath the location of the UST indicated concentrations of gasoline hydrocarbons. On January 28, 1992, Smith-Gufcher advanced four soil borings (TH-1 through TH-4) to a maximum depth of 70 fbg in and around the area of the former UST. Laboratory analysis of soil samples collected from the soil borings indicated gasoline-containing soil to a depth of approximately 55 fbg within an approximate 25-foot radius around the former UST at the site (see Attachment 1 for a summary of previous work). Gasoline-containing soils are believed to extend to at least 20 feet beneath the southwestern corner of the thrift store building. Groundwater was not encountered and is not anticipated above a depth in excess of 200 fbg. The known contaminant at the site has been identified a s HOLGUIN, Mr. Howard H. Wines, III BFDESD ~ F~ January 25, 2001- Page 5 ~ & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS petroleum hydrocarbons in the gasoline range. The total volume of hydrocarbon-containlng soils was estimated to be 3650 cubic yards, containing an estimated 2/120 pounds of hydrocarbons in the gasoline range. This equates to approximately 390 gallons of gasoline absorbed into the subsurface. Approximately 485 pounds of the hydrocarbons is estimated to be present beneath the thrift store building. HFA prepared a CAP dated June 17, 1996, for the site. A risk evaluation of the gasoline-containing soils at the site was conducted using American Society for Testing and Materials Designation: E-1739 Risk-Based Corrective Action Applied at Petroleum Release Sites (RBCA). The results of RBCA Tier 1 and 2 evaluations were that the indoor air inhalation pathway exceeds the permissible lifetime lx10-6 exposure levels given the concentration of benzene in the soils beneath the thrift store building and that mitigation is required to reduce these concentrations to a permissible residual level, which is protective of the health of the occupants of the building. An RI/FS was conducted to assess the feasibility and cost effectiveness of mitigation technologies. The RI/FS analysis concluded that in-situ vapor extraction is the cost-effective mitigative alternative, which is protective of the health of the current occupants of the building. The BFDESD, in its case review letter dated July 30, 1996, concurred with the conclusions of the RI/FS and requested initiation of in-situ vapor extraction. Saint Vincent De Paul obtained competitive bids to implement the CAP and submitted these bids to the SWRCB/USTCF for pre-approval of costs. The SWRCB/USTCF, in its letter dated June 4, 1997, denied pre-approval of costs to conduct active soil remediation and requested additional soil investigation to determine whether concentrations of gasoline hydrocarbons in the soils presented a health risk to the occupants of the building. On September 16, 1997, Smith-Gutcher advanced soil boring TH1 through the location of the 'former UST to a depth of 45 fbg. Gasoline hydrocarbon concentrations were detected in the soil samples collected from depths of 15, 20, 30, and 45 fbg (see Attachment 1). Given the results of the soils investigation, significant concentrations of gasoline hydrocarbons remained in the soils in and around the former UST, including beneath the southwestern corner of the thrift store building. Upon review of the laboratory analytical results, the SWRCB/USTCF requested that a soil vapor assessment be conducted to determine if gasoline hydrocarbon vapors were present in,the near-surface soils, which would present a risk of exposure to the occupants of the building. : HOLGUIN, Mr. Howard H. Wines, III BFDESD ~ FAHAN January 25, 2001- Page 6 ~ & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS On May 6, 1998, HFA collected soil vapor samples (G-1 through G-4) around the periphery of the foundation to assess whether gasoline hydrocarbons may be migrating into the thrift store building. HFA advanced an AMSTM soil gas vapor probe to a depth of 3 fbg at each location. Gasoline hydrocarbon concentrations were detected in soil vapor samples G-1 through G-4. However, TPH as gasoline and benzene concentrations were not detected in soil vapor samples G-1 through G-4 (see Attachment 1). Given the results of the soil vapor survey, the BFDESD, in its letter dated July 28, 1998, required 3 months of operation of the VES to reduce the potential migration of gasoline hydrocarbons into the thritt store building prior to considering the site for closure. During the first quarter of 1999, Saint Vincent De Paul obtained pre-approval of costs for active remediation from the SWRCB/USTCF. During the second quarter of 1999, SJVUAPCD-SR ATC Permit #S-3548-1-0 was obtained for the installation and operation of a VES at the site, and subsequently, seven 'vapor extraction wells (VW-1 through VW-7) were constructed. During the third quarter of 1999, the VES unit was delivered to the site and connected to electricity and supplemental fuel as well as the vapor extraction wells, and start-up system testing was performed (see Figure 3- VES Schematic Diagram and Figure 4 - VES Process Component Description). On October 11,' 1999, HFA began full-time operation of the VES, and the SJVUAPCD-SR conducted an inspection of the system on December 21, 1999. The SJVUAPCD-SR observed that the 'equipment was identical to that contained in the original permit, and the operating parameters were in compliance with the Conditions of the ATC permit. On December 21, 1999, January 28, 2000, February 29, 2000, and March 15, 2000, HFA performed vapor sampling of the influent and effluent streams of the thermal oxidizer. TPH as gasoline was detected in the influent vapor samples at concentrations of 371, 1,760, 659, and 1,190 ppmv for the December 21, 1999, January 28, 2000, February 29, 2000, and March 15, 2000/sampling events, respectively, and was not detected in the effluent samples (see Figure 5- Influent and Effluent TPH Concentrations, Table 1-Summary of Source Compliance Monitoring Analytical Results, and Table 2- Summary of VES Monitoring Data). HFA estimates the mass of gasoline hydrocarbons extracted from the subsurface since start-up to be approximately 5,383 pounds, which is equivalent to approximately 841 gallons of gasoline (see Figure 6 - Cumulative Extraction Curve and Table 2). At the end of the first quarter of 2000, the unit was shut down pending BFDESD site status review and determination whether additional active remediation is warranted or progress soil sampling should be conducted to determine the residual concentrations of gasoline 'hydrocarbons in the subsurface. 1he BFDESD, in its letter dated June 9, 2000, determined that an 'HOLGUIN, Mr. Howard H. Wines, III BFDESD ~ FAHAN January 25, 2001- Page 7 ,~: & ASSOCIATE~, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS additional 3 months of operation of the VES is warranted, Because of delays in the reimbursement of costs by the SWRCB/USTCF for the remediation activities, the public utilities had temporarily terminated service to the unit. Upon receiving reimbursement from the SWRCB/USTCF, and paying the back utility bills, the electricity and natural gas services were reinstated. However, service was not restored until after the end of the second quarter of 2000. Therefore, the VES unit was not restarted until the third quarter of 2000. REMEDIAL ACTION REPORT FOR THE FIRST QUARTER OF 2000 HFA has operated the VES unit 24 hours per day since start-up, with only short periods of inactivity for maintenance, draining of the knockout pot, and a few occurrences when the system has shut down. Inlet vapor concentrations ranged from 1,250 to 680 ppmv during the third quarter of 2000 (see Figure 5 - influent and Effluent TPH Concentrations and Table 2-Summary of VES Monitoring Data). On .August 30, 2000, HFA performed vapor sampling of the influent and effluent streams of the thermal oxidizer. The effluent sample collected was not sampled since it was ruptured in the laboratory prior to performing the analysis. TPH as gasoline was detected in the influent vapor sample at a concentration of 990 ppmv (see Table 1 and Attachment 2 for the laboratory reports). The inlet soil vapor flow rate has been maintained near the maximum stated in the ATC permit and-consistently ranges from 165 to 235 scfm. HFA estimates the mass of gasoline hydrocarbons extracted from the subsurface since start-up to be approximately 7,361 pounds, which is equivalent to approximately 1,150 gallons of gasoline (see Figure 6- Cumulative Extraction Curve and Table 2). ACTIVITIES PLANNED FOR THE FOURTH QUARTER OF 2000 During the fourth quarter of 2000, full-time operation of the VES will continue in accordance with the conditions of the ATC permit.

During the fourth quarter of 1999, full-time operation of the VES was initiated and continued through the end of the first quaffer of 2(X33, when the unit was shut down pending Cily of Bakers.field Fire Department EnvirOnmental Services Division (BFDESD) site status review and determination as to whether additional active remediation is warranted or progress soil sampii~ng should be conducted to determine the residual concentration of gasoline hydrocarbons in the subsurface. The BFDESD, in its letter dated June 9, 2000, determined that an additional 3 months of operation of the VES is warranted. Because of delays in the reimbursement of costs by the SWRCB/USTCF for the remediation activities, the public utilities had temporarily terminated service to the unit. Upon receiving reimbursement from the sWRCB/USTCF, and paying the back utility bills, the electricity and natural gas services were reinstated. However, service was not restored until after the end of the second quarter of 2000. Theretore, the VES unit was not restarted until the third quarter of 2000.

BACKGROUND GEOLOGY The site is located in a relatively flat area at an elevation of approximately 415 feet above MSL. The site is located in the southern portion of the Great Valley geomorphic province. The Great Valley is a north-south-trending valley, approximately 400 miles long by EO miles wide, the southern portion of which is known as the San Joaquin Valley. The surface of the San Joaquin Valley is composed primarily of unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Mio-Pliocene marine sediments, which extend to a crystalline basement at a depth of approximately 30,000 fbg. Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California DiVision of Mines and Geology, 1965, Geologic Map of California, Bakersfield Sheet). The site is an area at the foot of rolling hills reaching a maximum elevation of 900 feet above MSL, located on the eastern flank of the San Joaquin Valley and west of the southern Mr. Howard H. Wines, III BFDESD HOLGULN, October 10, 2000- Page 3 ~ & ASSOCIATES, INC. ENVlRO[~4MENTAL MANAGEMENT CONSULTANTS Sierra Nevada. The Kern River drains a large area of the southern Sierra' Nevada, including the highest part of the range at Mount Whitney. The modern river has cut a channel southeast of the site and provides recharge for groundwater along its course, Sedimentary geologic formations, observed at the surface and underlying the site were sourced by the Sierra Nevada and transported via the ancestral Kern River. In the region of the site, the Tertiary sedimentary sequence from top to bottom is nonmarine Kern River Formation, nonmarine Chanac Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to the tentative correlation of type Santa Margarita Formation west of the San Andreas Fault), marine Round Mountain Silt, marine Olcese Sand, marine Freeman Silt, marine Jewett Sand and Pyramid Hill member, marine Vedder Sand, nonmarine Walker Formation, Of these, only the Kern River, Chanac, and Santa Margarita formations are important to the hydrogeology of the site. The Tertiary, nonmarine Kern River Formation is unconformably overlain by bouldery terrace deposits of Quaternary Older Alluvium. Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the Tertiary (Miocene to Pliocene), nonmarine Kern River Formation and the Quaternary (Pleistocene) Older Alluvium. The Older Alluvium forms a thin terrace deposit lying unconformably on the Kern River Formation. Quaternary Older Alluvium: The middle to lower Pleistocene (Bartow, J.A., 1984, Geologic Map and Cross Sections of the Southeastern San Joaquin Valley, California, USGS Map 1-1496), Older Alluvium is a flat-lying terrace deposit approximately ,5 to 10 feet thick that overlies the erosional surface of the Kern River FOrmation. The Older Alluvium is composed of very coarse material, with boulders as large as 50 cm in diameter. Clastic material composition includes granitic and dioritic, crystalline rocks characteristic of the Sierra Nevada batholiths, quartzite characteristic of pre-batholithlc rocks, and volcanic and related rocks such as andesite and dark siliceous agate typical of the Neogene deposits of the Mojave Desert. In some locations, caliche rims have developed between clasts. Kern River Formation: The age of the Kern River Formation includes upper Miocene and Pliocene and possibly Pleistocene deposits. The Kern River Formation is composed of interstratified fanglomeratic deposits and silty claystones. Within the fanglomerates are conglomerate beds with cobbles as large as 20 cm in diameter, and in some areas fanglomerate beds exhibit cross bedding from 2.5 to 5 meters thick. The silty claystone beds, which would serve as iow-permeability barriers to ven'ical migration, are laterally continuous to as much as several thousand feet, but are locally truncated by sandy fanglomerate units. ~. ,~ Mr. Howard H. Wines, Ill BFDESD HOLGUIN, October 10, 2000- Page 4 ~ & A$$OCIATF_~, INC. ENV RONMEr~JTAL MANAGEMENT CONSULTANTS Another important factor in considering the potential for migration is the lack of secondary permeability within the Kern River Formation as no secondary cracks, small faults, or gypsum veins are observed. Chanac Formation: The Chanac Formation of upper Miocene age is not exposed on or near the site, but outcrops in the cliffs southeast of the site along the Kern River bluffs at Hart Park. It is a thinly bedded, chalky siltstone exhibiting many secondary cracks and gypsum veins. On-site soil borings indicate that the alluvium is characterized by highly permeable, fine-grained to coarse-grained sands interbedded with lower permeability, silt zones ranging in depth.from 24 to 27 fbg, 35 to 37 fbg, 44 to 57 fbg, and 63 to 70 fbg. The base of gasoline-containing soils is within the silty interval ranging in depth from 44 to 57 fbg. HYDROGEOLOGY Surface water and groundwater in the San Joaquin Valley are derived predominantly from the Sierra Nevada to the east, and are transported by five major rivers, the southernmost being the Kern River. The subject site is located approximately 2 miles south of the Kern River. The depth to the regional unconfined aquifer mapped by the Kern County Water Agency (KCWA) is approximately 200 fbg at the site, with the direction of groundwater flow to the southwest (KCWA, 1998, 1997 Report on Water Conditions, February 1, 1998). The nearest known occurrence of perched groundwater is 2 miles to the southwest at a depth of 20 fbg in the abandoned Kern River channel to the ancient Kern Lake bed (KCWA, 1998, 1995 Water Supply Report, January 1998). PREVIOUS WORK Based on a review of available data, analytical results, and conversations with Mr. Smith, on June 17, 1991, a 550-gallon gasoline UST, dispenser, and associated product piping were removed from the property. Laboratory analytical results of soil samples collected from beneath the location of the UST indicated concentrations of gasoline hydrocarbons. On January 28, 1992, Smith-Gutcher advanced four soil borings (TH-1 through TH-4) to a maximum depth of 70 fbg in and around the area of the former UST, Laboratory analysis of soil samples collected from the soil borings indicated gasoline-containing soil to a depth of approximately 55 fbg within an approximate 25-foot radius around the former UST at the site (see Attachment 1 for a summary of previous work). Gasoline-containing soils are believed to extend to at least 20 feet beneath the southwestern corner of the thrift store building. Groundwater was not encountered and is not anticipated above a depth in excess of 200 fbg. The known contaminant at the site has been identified a s Mr. Howard H. Wines, ,~__~,~ HOLGUIN, BFDESD F~ October 10, 2000- Page 5 ~ & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS Petroleum hydrocarbons in the gasoline range. The tofal volume of hydrocarbon-containing soils was estimated to be 3,~50 cubic yards, confaining an estimated 2A20 pounds of hydrocarbons in the gasoline range. This equates fo approximately Sg0 gallons of gasoline absorbed into the subsurface. Approximately 485 pounds of the hydrocarbons is estimated to be present beneath the thrift store building. HFA prepared a CAP dated June 17, 1996, for the site. A risk evaluation of the gasoline-containing soils at the site was conducted using American Society for Testing and Materials Designation: E-1739 Risk:Based CorrectiVe Action Applied at Petroleum Release Sites (RBCA). The results of RBCA Tier 1 and 2 evaluations were that the indoor air inhalation pathway exceeds the permissible lifetime 1x10-6 exposure levels given the concentration of benzene in the soils beneath the thrift store building and that mitigation is required to reduce these concentrations to a permissible residual level, which is protective of the health of the occupants of the building. An RI/FS was conducted to assess the feasibility and Cost effectiveness of mitigation technologies. The RI/FS analysis concluded that in-situ vapor extraction is the cost-effective mitigative alternative, which is protective of the health of the current occupants of the building. The BFDESD, in its case 'review letter dated July 30, 1996, concurred with the conclusions of the RI/FS and requested initiation of in-situ vapor extraction. Saint Vincent De Paul obtained competitive bids to implement the CAP and submitted these bids to the SWRCB/USTC'F for pre-aPproval of costs. The SWRCB/USTCF, in its letter dated June 4, 1997, denied pre-approval of costs to conduct active soil remediation and requested additional soil investigation to determine whether concentrations of gasoline hydrocarbons in the soils presented a health risk to the occupants of the building. On September 16, 1997, Smith-Gutcher advanced soil boring TH1 through the location of the former UST to a depth of 45 fbg. Gasoline hydrocarbon concentrations were detected in the soil samples collected from depths of 15, 20, 30, and 45 fbg (see Attachment 1). Given the results of the soils investigation, significant concentrations of gasoline hydrocarbons remained in the soils in and around the former UST, including beneath the southwestern corner of the thrift store building. Upon review of the laboratory analytical results, the SWRCB/USTCF requested that a soil vapor assessment be conducted to determine if gasoline hydrocarbon vapors were present in the near-surface soils, which would present a risk of exposure to the occupants of the building, Mr. Howard H. Wines, BFDESD HOLGUIN, October 10, 2000- I~age 6 & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS On May 6 1998, HFA collected soil vapor samples (G-1 through G-4) around the peripheryi of the foundation to assess whether gasoline hydrocarbons may be migrating into the 'thrift. store building. HFA advanced an AMSTM soil gas vapor probe to a depth of 3 fbg at each Io~ation. Gasoline hydrocarbon concentrations were detected in soil vapor samples G-1 through G-4. However, TPH as gasoline and benzene concentrations were not detected in soil ,vapor samples G-1 through G-4 (see Attachment 1). Given the results of the soil vapor survey, the BFDESD, in its letter dated July 28, 1998, required 3 months of operation of the VES to reduce the potential migration of gasoline hydrocarbons into the thrift store building prior to considering the site for closure, During the first quarter of 1999, Saint Vincent De Paul obtained pre-approval of costs for ~ctive remediation from the SWRCB/USTCF. During the second quaffer of 1999, SJVUAPCD-SR ATC Permit #S-3548-1-0 was obtained for the installation and operation of a VES at the site~, and subsequently, seven vapor extraction wells (VW-1 through VW-7) were constr0cted. During the third quaffer of 1999, the VES unit was delivered to the site and connect, ed to electricity and supplemental fuel as well as the vapor extraction wells, and staff-up system testing was performed (see Figure 3- VES Schematic Diagram and Figure 4 - VES Piocess Component Description). On October 11, 1999, HFA began full-time operation of the VES, and the SJVUAP,CD-SR conducted an inspection of the system on December 21, 1999. The SJVUAPCD-SR observed that the equipment was identical to that contained in the original permit, and the ope~rating parameters were in compliance with the conditions of the ATC permit. On December 2i, 1999, January 28, 2000, February 29, 2000, and March 15, 2000, HFA performed vapor sampling of the influent and effluent streams of the thermal oxidizer. TPH as gasoline was detected !in the influent vapor samples at concentrations of 371, 1,760, 659, and 1,190 ppmv for the December 21, 1999, January 28, 2000, February 29, 2000, and March 15, 2000, sampling events, respectively, and was not detected in the effluent samples (see Figure 5- Influent and Effluent TPH Concentrations, Table 1-Summary of Source Compliance Monitoring Analytical Rbsults, and Table ~2- Summary of VES Monitoring Data). HFA estimates the mass of gc~soline hydrocarbons extracted from the subsurface since start-up to be approximately 5.383 pounds, which is equivalent to approximately 841 gallons of gasoline (see Figure 6 - Cumulative ExtraCtion Curve and Table 2). At the end of the first quarter of 2000, the unit was shut down pending BFDESD site status r, eview and determination whether additional active remediation is warranted or progre§s soil sampling should be conducted to determine the residual concentrations of g~soline hydrocarbons in the subsurface. The BFDESD, in its letter dated June 9, 2000, determined that an '1 Mr. Howard H. Wines, iii ~ HOLGUIN, BFDESD ~ F/~_~XT October 10, 2000- Page,~ 7 '~ &ASSOCIATES, INC.

However, service was not restored until after the end of the second quarter of 2000. Therefore, the VES unit was not restarted until the third quarter of 2000.

(HFA) Is pleased to present this First Quarter 2000 Progress Report of the ongoing remedial action being conducted in association with the former UST at .' the above-referenced property. During the first quarter of 1999, Saint Vincent De Paul obtained Pre-approval of costs for active remediation from the State Water Resources Control Board/Underground Storage Tank Cleanup Fund (SWRCB/USTCF). During the second quarter of 1999, the San Joaquin Valley Unified Air Pollution Control District - Southern Region (SJVUAPCD-SR] Issued ATC Permit #S-3548-1-0 for the Installation and operation of the VES at the site, During the second quarter of 1999, the seven VES wells were also constructed. During the third quarter of 1999; the VES unit was delivered to the site and connected to electricity and supplemental fuel as well as the vapor extraction wells, and stad-up system testing was performed. DUring the fourth quarter of 1999, full-time operation of the VES was Initiated and continued through the end of the first quarter of 2000, when the unit was shut down pending City of Bakersfield Fire Department Environmental Services Division (BFDESD) site status review and determination as to whether additional active remediation is warranted or progress soil sampling should be conducted to determine the residual concentration of gasoline hydrocarbons in the subsurface. If the BFDESD determines that additional operation of the VES is warr, anted, then HFA will restart the VES and continue operation through the end of the second quarter of 2000, when the site status will again be reviewed, if the BFDESD determines that a remediation soil assessment be performed, then HFA will provide the BFDESD with a work plan to perform the requested soil assessment.

TheGreat Valley is a north-south-trending valley, approximately 400 miles long by 50 miles wide, the southern portion of which is known as the San Joaquin Valley. The surface of the San Joaquin Valley ts composed primarily of unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Mio-pliocene marine sediments, which extend to a crystalline basement at a depth of approximately 30,000 fbg. Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Division of Mines and Geology, 1965, Geologic Map of California, Bakersfield Sheet). The site is an area at the foot of rolling hills reaching a maximum elevation of 900 feet above MSU located on the eastern flank of the San Joaquin Valley and west of the southern ~ HOLGUIN, F,/~-lzad'~ Mr. Howard H. Wines, III ' ~ BFDESD ~ & ASSOCIATES, ING. May lO, 2000- Page 3 ENVIRONMENTAL MANAGEMENT CONSULTANTS Sierra Nevada. The Kern River drains a large area of the southern Sierra Nevada, including the highest part of the range at Mount Whitney. The modern river has cut a channel southeast of the site and provides recharge for groundwater along its course. Sedimentary geologic formations, observed at the surface and underlying the site were sourced by the Sierra Nevada and transported via the ancestral Kern River. In the reg!on of the site, the Tertiary sedimentary sequence from top to bottom is nonmarine Kern River Formation, nonmarine Chanac Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to the tentative correlation of type Santa Margarita Formation west of the San Andreas Fault), marine Round Mountain Silt, marine Olcese Sand, marine Freeman Silt, marine Jewett Sand and Pyramid Hill member, marine Vedder Sand, nonmarine Walker Formation. Of these, only the Kern River, Chanac, and Santa Margarita formations are important to the hydrogeology of the site. The Tertiary, nonmarlne Kern River Formation is unconformably overlain by bouldery terrace deposits of Quaternary Older Alluvium. Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the Tertiary (Miocene to Pliocene), nonmarine Kern River Formation and the Quaternary (Pleistocene) Older Alluvium. The Older Alluvium forms a thin terrace deposit lying unconformably on the Kern River Formation. Quaternary. Older Alluvium: The middle to lower Pleistocene (Bartow, J.A., 1984, Geologic Map and Cross Sections of the Southeastern San Joaquin Valley, California, USGS Map 1-1496), Older Alluvium is a flat-lying terrace deposit approximately 5 to 10 feet thick that overlies the erosional surface of the Kern River Formation. The Older Alluvium is composed of very coarse material, with boulders as large as 50 cm in diameter. Clastic material composition includes granitic and dioritic, crystalline rocks characteristic of the Sierra Nevada batholiths, quartzite characteristic of Pre-batholithic rocks, and volcanic and related rocks such as andesite and dark siliceous agate typical of the Neogene deposits of the Mojave Desert. In some locations, caliche rims have developed between clasts. Kern River FQrmatlon: The age of the Kern River Formation includes upper Miocene and Pliocene and possibly Pleistocene deposits. The Kern River Formation is composed of interstratified fanglomeratic deposits and silty claystones. Within the fanglomerates are conglomerate beds with cobbles as large as 20 cm in diameter, and in some areas fanglomerate beds exhibit cross bedding from 2.5 to 5 meters thick. The silty claystone beds, which would serve as Iow-permeability barriers to vertical migration, are laterally continuous to as much as several thousand feet, but are locally truncated by sandy fanglomerate units. ~ HOLGUIN, ~ F/~-t./~ Mr, Howard H.iWines, III ~ & ASSOCIATES, INC. BFDESD May 10, 2000 - Page 4 ENVIRONMENTAL MANAGEMENT CONSULTANTS Another important factor in considering the potential for migration is the lack of secondary permeability within the Kern River Formation as no secondary cracks, small faults, or gypsum veins are observed. Chanac Formation: The Chanac Formation of upper Miocene age is not exposed on or near the site, but outcrops in the cliffs southeast of the site along the Kern River bluffs at Hart Park. It is a thinly bedded, chalky siltstone exhibiting many secondary cracks and gypsum veins. On-site soil borings indicate that the alluvium is characterized by highly permeable, fine-grained to coarse-grained sands Interbedded with lower permeability, silt zones ranging in depth from 24 to 27 fbg,. 35 to 37 fbg, 44 to 57 fbg, and 63 to 70 fbg. The base of gasoline-containing soils is within the silty interval ranging in depth from 44 to 57 fbg. HYDROGEOLOGY Surface water and groundwater in the San Joaquin Valley are derived predominantly from the Sierra Nevada to the east, and are transported by five major rivers, the southernmost being the Kern River. The subject site is located approximately 2 miles soUth of the Kern River. The depth to the regional unconfined aquifer mapped by the Kern County Water Agency (KCWA) is approximately 200 fbg at the site, with the direction of groundwater flow to the southwest (KCWA, 1998, 1997 Report on Water Conditions, February 1, 1998). The nearest known occurrence of perched groundwater Is 2 miles to the southwest at a depth of 20 fbg In the abandoned Kern River channel to the ancient Kern Lake bed (KCWA, 1998, 1995 Water Supply Report, January 1998). PREVIOUS WORK Based on a review of available data, analytical results, and conversations with Mr. Smith, on June 17, 1991, a 550-gallon gasoline UST, dispenser, and associated product piping were removed from the property. Laboratory analytical results of soil samples collected from beneath the location of the UST indicated concentrations of gasoline hydrocarbons. On January 28, 1992, Smith-Gutcher advanced four soil borings (TH-1 through TH-4) to a maximum depth of 70 fbg tn and around the area of the former UST. Laboratory analysis of soil samples collected from the soil borings indicated gasoline-containing soil to a depth of approximately 55,fbg within an approximate 25-foot radius around the former UST at the site (see Attachment 1 for a summary of previous work). Gasoline-containing soils are believed to extend to at least 20 feet beneath the southwestern corner of the thrift store building. Groundwater was not encountered and Is not anticipated above a depth in excess of 200 fbg. The known contaminant at the site has been identified as ~[ HOLGUIN, F~ Mr. Howard H. Wines, Ill BFDESD & ASSOCIATES, INC. May 10, 2000- Page 5 ENVIRONMENTAL MANAGEMENT CONSULTANTS petroleum hydrocarbons in the gasoline range. The total volume of hydrocarbon-containing soils was estimated to be 3,650 cubic yards, containing an estimated 2~20 pounds of hydrocarbons in the gasoline range. This equates to approximately 390 gallons of gasoline absorbed into the subsurface. Approximately 485 pounds of the hydrocarbons is estimated to be present beneath the thrift store building. HFA prepared a CAP dated June 17, 1996, for the site. A risk evaluation of the gasoline-containing soils at the site was conducted using American Society for Testing and Materials Designation: G1739 Risk-Based Corrective Action Applied at Petroleum Release Sites (RBCA). The results of RBCA Tier 1 and 2 evaluations were that the indoor air inhalation pathway exceeds the permissible lifetime lx10.6 exposure levels given the concentration of benzene in the soils beneath the thrift store building and that mitigation is required to reduce these concentrations to a permissible residual level, which is protective of the health of the occupants of the building. An RI/FS was conducted to assess the feasibility and cost effectiveness of mitigation technologies. The RI/FS analysis concluded that inositu vapo~ extraction is the cost-effective mitigative alternative, which is protective of the health of the current occupants of the building. The BFDESD, in its case review letter dated July 30, 1996, concurred with the conclusions of the RI/FS and requested initiation of in-situ vapor extraction. Saint Vincent De Paul obtained competitive bids to implement the CAP and submitted these bids to the-SWRCB/USTCF for pre-approval of costs. The SWRCB/USTCF, in its letter dated June 4, 1997, denied pre-approval of costs to conduct active soil remediation and requested additional soil investigation to determine whether concentrations of gasoline hydrocarbons in the soils presented a health risk to the occupants of the building. On September 16, 1997, Smith-Gutcher advanced soil boring TH1 through the location of the former UST to a depth of 45 fbg. Gasoline hydrocarbon concentrations were detected in the soil samples collected from depths of 15, 20, 30, and 45 fbg (see Attachment 1). Given the results of the soils investigation, significant concentrations of gasoline hydrocarbons remained in the soils in and around the former UST, Including beneath the southwestern corner of the thrift store building. Upon review of the laboratory analytical results, the SWRCB/USTCF requested that a soil vapor assessment be conducted to determine if gasoline hydrocarbon vapors were present in the near-surface soils, which would present a risk of exposure to the occupants of the building. ]all~~~~ o_HOLGUIN' .FAHAN Mr. Howard H. Wines, ill BFDESD ASSOCIATES, INC. May 10, 2000- Page 6 ENVIRONMENTAL MANAGEMENT CONSULTANTS On May 6, 1998, HFA collected soil vapor samples (G-1 through G-4) around the periphery of the foundation to assess whether gasoline hydrocarbons may be migrating into the thrift store building. HFA advanced an AMSTM soil gas vapor probe to a depth of 3 flog at each location. Gasoline hydrocarbon concentrations were detected in soil vapor samples G-1 through G-4. However, TPH as gasoline and benzene concentrations were not detected in soil vapor samples C--1 through G-4 (see Attachment 1). Given the results of the soil vapor survey, the BFDESD, in its letter dated July 28, 1998, required 3 months of operation of the VES to reduce the potential migration of gasoline hydrocarbons into the thrift store building prior to considering the site for closure. During the first quarter of 1999, Saint Vincent De Paul obtained pre-approval of costs for active remediation from the SWRCB/USTCF. During the second quarter of 1999, SJVUAPCD-SR ATC Permit #S-3548-1-0 was obtained for the installation and operation of a VES at the site, and subsequently, seven vapor extraction wells (VW-1 through VW-7) were constructed. During the third quarter of 1999, the VES unit was delivered to the site and connected to electricity and supplemental fuel as well as the vapor extraction wells, and start-up system testing was performed (see Figure 3- VES Schematic Diagram and Figure 4 - VES Process Component Description). On October 11, 1999, HFA began full-time operation of the VES, and the SJVUAPCD-SR conducted an inspection of the system on December 21, 1999. The SJVUAPCD-SR observed that the equipment was identical to that contained in the original permit, and the operating- parameters were in compliance with the conditions of the ATC permit. On December 21, 1999, HFA performed vapor sampling of the influent and effluent streams of the thermal oxidizer. TPH as gasoline was detected in the influent vapor sample at a concentration of 371 ppmv and was not detected In the effluent sample (see Table 1 - Summary of Source Compliance Monitoring Analytical Results). REMEDIAL ACTION REPORT FOR THE FIRST QUARTER OF 2000 HFA has operated the VES unit 24 hours per day since start-up, with only short periods of inactivity for maintenance, draining of the knockout pot, and a few occurrences when the system has shut down. Inlet vapor concentrations ranged from 370 to 1200 ppmv during the first quarter of 2000 (see Figure 5 - influent and Effluent TPH Concentrations and Table 2 - Summary of VES Monitoring Data). On January 28, 2000, February 29, 2000, and March 15, 2000, HFA performed vapor sampling of the influent and effluent streams of the thermal oxidizer. TPH as gasoline was detected in the influent vapor sample at concentrations of 1,760, 659, and 1,190 ppmv for the ]~ HOLGUIN, F.,a~q.,,~ Mr. Howard H. Wines, III BFDESD & ASSOCIATE. S, INC.

The inlet soil vapor flow rate has been maintained near the maximum stated in the ATC permit and consistently ranges from 150 to 225 scfm. HFA estimates the mass of gasoline hydrocarbons extracted from the subsurface since start-up to be approximately 5,383 pounds, which is equivalent to approximately 841 gallons of gasoline (see Figure 6 - Cumulative Extraction Curve and Table 2). At the end of the first quarter of 2000, the unit was shut down pending BFDESD site status review and determination whether additional active remedlatlon is warranted or progress soil samPling should be conducted to determine the residual concentrations of gasoline hydrocarbons in the subsurface. If the BFDESD determines that additional operation of the VES is warranted, then HFA will restart the VES and continue operation through the end of the second quarter of 2000, when the site status will again be reviewed. If the BFDESD determines that a remediatlon soil assessment be performed, then HFA will provide the BFDESD with a work plan to perform the requested soil assessment. Because operation of the VES remained cost effective for the removal of gasoline hydrocarbons from the subsurface with approximately 2.84 lbs/hr being extracted from the subsurface at the time the system was shut down, HFA recommends that an additional quarter of VES operation is warranted. ACTIVITIES PLANNED FOR THE SECOND QUARTER OF 2000 During the second quarter of 2000, full-time operation of the VES will be reinitiated in accordance with the conditions of the ATC permit, if requested by the BFDESD. Otherwise, remedlation progress soil sampling will be performed upon approval by the BFDESD of a soil sampling work plan. ~ HOLGUIN, ? F/~I/~ Mr. Howard H. Wines, : ~ BFDESD ~ ~ & ASSOCIATES, INC.

BACKGROUND GEOLOGY The site is located in a relatively flat area at an elevation of approximately 415 feet above MSL. The site is located in the southern portion of the Great Valley geomorphic province. The Great Valley is a north-south-trending valley, approximately 403 miles long by ~] miles wide, the southern portion of which is known as the San Joaquin Valley. The surface of the San Joaquin Valley is composed primarily of unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Mio-Pliocene marine sediments, which extend to a crystalline basement at a depth of approximately 30,000 fbg. Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Division of Mines and Geology, 1965, Geologic Map of California, Bakersfield Sheet). The site is an area at the foot of rolling hills reaching a maximum elevation of (;(]0 feet above MSL, located on the eastern flank of the San Joaquin Valley and west of the southern Sierra Nevada. The Kern River drains a large area of the southern Sierra Nevada, including the highest part of the range at Mount Whitney. The' modern river has cut a channel southeast of the site and provides recharge for groundwater along its course. Sedimentary geologic formations, observed at the surface and underlying the site were sourced by the Sierra Nevada and transported via the ancestral Kern River. In the region of the site, the Tertiary sedimentary sequence from top to bottom is nonmarine Kern River Formation, nonmarine Chanac Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to the tentative correlation of type Santa Margarita Formation west of the San Andreas Fault), marine Round Mo~Jntain Silt, marine Olcese Sand, marine Freeman Silt, marine Jewett Sand and Pyramid Hill member, marine Vedder Sand, nonmarine Walker Formation. Of these, only the Kern River, Chanac, and Mr. Howard H. Wines, HOLGUIN, BFDESD FAHAN March 8, 2000 - page 3 & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS Santa Margarita formations are important to the hydrogeology of the site. The Tertiary, nonmarine Kern River Formation is unconformably overlain by bouldery terrace deposits of Quaternary Older Alluvium. Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the Tertiary (Miocene to Pliocene), nonmarine Kern River Formation and the Quaternary (Pleistocene) Older Alluvium. The Older Alluvium forms a thin terrace deposit lying unconformably on the Kern River Formation. Quaternary Older Alluvium: The middle to lower Pleistocene (Bartow, J.A., 1984, Geologic Map and Cross Sections of the Southeastern San Joaquin Valley, California, USGS Map 1-1496), Older Alluvium is a f/at-lying terrace deposit approximately 5 to 10 feet thick that overlies the erosional surface of the Kern River Formation. The Older Alluvium is composed of very coarse material, with boulders as large as 50 cm in diameter. Clastic material composition includes granitic and dioritic, crystalline rocks characteristic of the Sierra Nevada batholiths, quartzite characteristic of pre-batholithic rocks, and volcanic and related rocks such as andesite and dark siliceous agate typical of the Neogene deposits of the Mojave Desert. in some locations, caliche rims have developed between clasts, Kern River Formation: The age of the Kern River Formation includes upper Miocene and Pliocene and possibly Pleistocene deposits. The Kern River Formation is composed of interstratified fanglomeratic deposits and silty claystones. Within the fanglomerates are conglomerate beds with cobbles as large as 20 cm in diameter, and in some areas fanglomerate beds exhibit cross bedding from 2.5 to 5 meters thick. The silty daystone beds, which would serve as Iow-permeability barriers to vertical migration, are laterally continuous to as much as several thousand feet, but are locally truncated by sandy fanglomerate units. Another important factor in considering the potential for migration is the lack of secondary 'permeability within the Kern River Formation as no secondary cracks, small faults, or gypsum veins are observed.- Chanac Formation: The Chanac Formation of upper Miocene age is not exposed on or near the site, but outcrops in the cliffs southeast of the site along the Kern River bluffs at Hart Park. It is a thinly bedded, chalky siltstone exhibiting many secondary cracks and gypsum veins. On-site soil borings indicate that the alluvium is characterized by highly permeable, fine-grained to coarse-grained sands interbedded with lower permeability, silt zones ranging in depth from 24 to 27 fbg, 35 to 37 fbg, 44 to 57 fbg, and 63 to 70 fbg. The base of gasoline-containing soils is within the silty interval ranging in depth from 44 to 57 fbg. Mr. Howard H. Wines, iii HOLGUIN, BFDESD 1. March 8, 2000- Page 4 FAHAN & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS HYDROGEOLOGY Surface water and groundwater in the San Joaquin Valley are derived predominantly from the Sierra Nevada to the east, and are transported by five major rivers, the southernmost being the Kern River. The subject site is located approximately 2 miles south of the Kern River. The depth to the regional unconfined aquifer mapped by the Kern County Water Agency (KCWA) is approximately 200 fbg at the site, with the direction of groundwater flow to the southwest (KCWA, 1998, 1997 Report on Water Conditions, February 1, 1998). The nearest known occurrence of perched groundwater is 2 miles to the southwest at a depth of 20 fbg in the abandoned Kern River channel to the ancient Kern Lake bed (KCWA, 1998, 1995 Water Supply Report, January 1998). PREVIOUS WORK Based on a review of available data, analytical results, and conversations with Mr. Smith, on June 17, 1991, a 550-gallon gasoline UST, dispenser, and associated product piping were removed from the property. Laboratory analytical results of soil samples collected from beneath the location of the UST indicated concentrations of gasoline hydrocarbons. On January 28, 1992, Smith-Gutcher advanced four soil borings (TH-1 through TH-4) to a maximum depth of 70 fbg in and around the area of the former UST. Laboratory analysis of soil samples collected from the soil borings indicated gasoline-containing soil to a depth of approximately 55 fbg within an approximate 25-foot radius around the former UST at the site (see Attachment 1 for a summary of previous work). · Gasoline-containing soils are believed to extend to at least 20 feet beneath the southwestern corner of the thrift store building. Groundwater was not encountered and is not anticipated above a depth in excess of 200 fbg. The known contaminant at the site has been identified as petroleum hydrocarbons in the gasoline range. The total volume of hydrocarbon-containing soils Was estimated to be 3,650 cubic yards, containing an estimated 2~20 pounds of hydrocarbons in the gasoline range. This equates to approximately 390 gallons of gasoline absorbed into the sul~surface. Approximately 485 pounds of the hydrocarbons is estimated to be present beneath the thrift store building. HFA prepared a CAP dated June 17, 1996, for the site. A risk evaluation of the gasoline-containing soils at the site was conducted using American Society for Testing and Materials Designation: E-1739 Risk-Based Corrective Action Applied at Petroleum Release Sites (RBCA). The results of RBCA Tier 1 and 2 evaluations were that the indoor air inhalation pathway exceeds the permissible lifetime lx10-6 exposure levels given the concentration of benzene in the soils beneath the thrift store building and that mitigation is required to reduce these Mr. Howard H. Wines, III HOLGUIN, BFDESD I March 8, 2000- Page 5 FAHAN & ASSC IATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS concentrations to a permissible residual level, which is protective of the health of the occupants of the building. An RI/FS was conducted to assess the feasibility and cost effectiveness of mitigation technologies. The RI/FS analysis concluded that in-situ vapor extraction is the cost-effective mitigative alternative, which is protective of the health of the current occupants of the building. The City of Bakersfield Fire Department Environmental Services Division (BFDESD), in its case review letter dated July 30, 1996, concurred with the conclusions of the RI/FS and requested initiation of in-situ vapor extraction. Saint Vincent De Paul obtained competitive bids to implement the CAP and submitted these bids to the State Water Resources Control Board/Underground Storage Tank Cleanup Fund (SWRCB/USTCF) for pre-approval of costs. The SWRCB/USTCF, in its letter dated June 4, 1997, denied pre-approval of costs to conduct active soil remediation, and requested additional soil investigation to determine whether concentrations of gasoline hydrocarbons in the soils presented a health risk to the occupants of the building. On September 16, 1997, Smith-Gutcher advanced soil boring TH1 through the location of the former UST to a depth of 45 fbg. Gasoline hydrocarbon concentrations were detected in the soil samples collected from depths of 15, 20, 30, and 45 fbg (see Attachment 1). Given the results of the soils investigation, significant concentrations of gasoline hydrocarbons remained in the soils in and around the former UST, including beneath the southwestern corner of the thrift store building. Upon review of the laboratory analytical results, the SWRCB/USTCF requested that a soil vapor assessment be conducted to determine if gasoline hydrocarbon vapors were present in the near-surface soils, which would present a risk of exposure to the occupants of the building. On May 6, 1998, HFA collected soil vapor samples (G-1 through G-4) around the periphery of the foundation to assess' whether gasoline hydrocarbons may be migrating into the thrift store building. HFA advanced an AMSTM soil gas vapor probe to a depth of 3 fbg at each location. Gasoline hydrocarbon concentrations were detected in soil vapor samples G-1 through G-4. However, TPH as gasoline and benzene concentrations were not detected in soil vapor samples G-1 through G-4 (see Attachment 1). Given the results of the soil vapor survey, the BFDESD, in its letter dated July 28, 1998, required 3 months of operation of the VES to reduce the potential migration of gasoline hydrocarbons into the thrift store building prior to considering the site for closure. Mr. Howard H. Wines, III HOLGUIN, BFDESD FAHAN March 8, 2000 - Page 6 & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS During the first quarter of 1999, Saint Vincent De Paul obtained pre-approval of costs for active remediation from the SWRCB/USTCF. During the second quarter of 1999, SJVUAPCD-SR ATC Permit #S-3548-1-0 was obtained for the Installation and operation of a VES at the site, and subsequently, seven vapor extraction wells (VW-1 through VW-7) were constructed. During the third quarter of 1999, the VES unit was delivered to the site and connected to electricity and supplemental fuel as well as the vapor extraction wells, and start-up system testing was performed (see Figure 3- VES Schematic Diagram and Figure 4 - VES Process Component Description). REMEDIAL ACTION REPORT FOR THE FOURTH QUARTER OF 1999 On October-11, 1999, HFA began full-time operation of the VES, and the SJVUAPCD-SR conducted an inspection of the system on December 21, 1999. The SJVUAPCD-SR observed that the equipment was identical to that contained in the original permit, and the operating parameters were in compliance with the conditions of the ATC permit. On December 21, 1999, HFA performed vapor sampling of the influent and effluent streams of the thermal oxidizer. TPH as gasoline was detected in the influent vapor sample at a concentration of 371 ppmv and was not detected in the effluent sample (see Table 1 - Summary of Source Compliance Monitoring Analytical Results and Attachment 2 for the laboratory report), HFA has operated the VES unit 24 hours per day since start-up, with only short periods of inactivity for maintenance, draining of the knockout pot, and a few occurrences when the system has shut down. Inlet vapor concentrations ranged from 370 to 1200 ppmv during the fourth quarter of 1999 (see Figure 5- lnfluent and Effluent TPH Concentrations and Table 2 - Summary of VES Monitoring Data), The inlet soil vapor flow rate has been maintained near the maximum stated in the ATC permit and consistently rc~nges from 150 to 225 scfm. HFA estimates the mass of gasoline hydrocarbons extracted from the subsurface since start-up to be approximately 1,935 pounds, which is equivalent to approximately 302 gallons of gasoline (see Figure 6 - Cumulative Extraction Curve and Table 2). ACTIVITIES PLANNED FOR THE FIRST QUARTER OF 2000 During the first quarter of 2000, full-time operation of the VES will continue in accordance with the conditions of the ATC permit. ~,, ',' ~ HOLGUIN, Mr. Howard H.

HFA has conducted sampling of the influent and effluent concentrations of gasoline hydrocarbons and BTEX in accordance with Conditions #5 and ~6 of the ATC permit. This study indicates that the total VOC emissions of the system comply with Conditions #14 and ~22. In addition, HFA has conducted weekly field monitoring of the influent and effluent VOC emissions using a PID In accordance with Condition ~. This field monitoring is in compliance with Conditions #14 and ¢22 for total VOC emissions. Therefore, HFA respectfully requests that the ATC permit status be upgraded to a PTO, BACKGROUND The Saint Vincent De Paul Thrift Store is located at ~ Baker Street, Bakersfield, Kern County, California. The topography at the site is relatively fiat, with a slight slope to. the southwest (see Figure 1 - Site Location Map). The subject site is bound on the east by Baker Street, on the south by Chico Street, and on the west and north by commercial properties. The property Is located in the southeastern quarter of the southwestern quarter of Section 29, T29S, R28E, MDBM, and is identified as APN 016-32[~15OG2. The property is situated within a developed commercial and light industrial area, interspersed with residential properties. A 550-gallon gasoline UST, dispenser, and associated product piping were previously removed from the site (see Figure 2 - PIct Plan Showing VES).

Inc.. 2820 Pegasus Drive, Suite 1, Bakersfield, California, 93308, (661 ) 391-0517, SITE HISTORY On June 17, 1991, a 550-gallon gasoline UST, dispenser, and associated product piping were removed from the property. Soil samples collected from beneath the location of the UST indicated 'concentrations of gasoline hydrocarbons. On January 28, 1992, Smith-Gutcher advanced four soil borings (TH-1 through TH-4) to a maximum depth of 70 fbg in and around the area of the former UST. Laboratory analysis of soil samples collected from the soil borings indicated gasoline-containing soil to a depth of approximately 55 fbg within an approximate 25-foot radius around the former UST (see Attachment 1 for a summary of previous work). Gasoline-containing soils are believed to extend to at least 20 feet beneath the southwestern corner of the thrift store building. Groundwater was not encountered and is not anticipated above a depth in excess of 200 fbg. The known contaminant at the site has been identified as petroleum hydrocarbons in the gasoline range. The total volume of hydrocarbon-containing soils was estimated to be 3,650 cubic yards, containing an estimated 2~120 pounds of hydrocarbons in the gasoline range. This equates to approximately 390 gallons of gasoline absorbed into the subsurface. Approximately 485 pounds of the hydrocarbons was estimated to have been present beneath the thrift store building. The results of the risk evaluation included in HFA's CAP submitted on June 17, 1996, were that the indoor air inhalation pathway exceeds the permissible lifetime 1x10-6 exposure levels given the concentration of benzene in the soils beneath the thrift store building and that mitigation is required to reduce these concentrations to a permissible residual level that is protective of the health of the occupants of the building. The RI/FS analysis also included in the CAP determined that in-situ vapor extraction is the cost-effective alternative that is protective of the health of the current occupants of the building. The BFDESD, in its case review letter dated July 30, 1996, concurred with the conclusions and recommendations of the CAP and requested that Saint Vincent De Paul initiate active soil remediation in the form of in-situ vapor extraction. Saint Vincent De Paul obtained competitive bids to implement the CAP and submitted these bids to the State Water Resources Control Board/Underground Storage 'tank Cleanup Fund (SWRCB/USTCF) for pre-approval of costs. FAHAN February 8, 2000- Page 3 & INC. ENVif:aONMENT/~,L MANAGEMENS CONSUI_'¥ANTS The SWRCB/USTCF, in ils leHer dated June 4, ]997, denied pre-approval al costs 1o conduct active soil remediation, and requested performance of additional soils investigation to determine whether concenhations of gasoline hydrocarbons in the soils present a health risk to the occupants of the building. On September ]6, ]997, Smith-Gutcher advanced soil boring TH] through the Iocatic}n of the former UST to a depth of 45 fbg. Gasoline hydrocarbon concentrations were detected in the soil samples collected from depths of 15, 20, 30, and 45 fbg (see Attachment ]). Given the results of the soils investigation, significant concentrations of gasoline hydrocarbons remained in the soils in and around the former UST including beneath the southwestern corner of the thrift store building. Upon review of the laboratory analytical results, the SWRCB/USTCF requested that a soil 9apor assessment be conducted to determine if gasoline hydrocarbon vapors were present in the near-surface soils, which would present a risk of exposure to the occupants of the building. On May 6, ]998, HFA collected soil vapor samples (G-] through G-4) around the periphery of the foundation to assess whether gasoline hydrocarbons may be migrating into the thrift store building. HFA advanced an AMSTM soil gas vapor probe to a depth of 3 fbg at each location. Gasoline hydrocarbon concentrations were detected in soil vapor samples G-1 through G-4. However, TPH as gasoline and benzene concentrations were not detected in soil vapor samples G-1 through G-4 (see Attachment l). Given the results of the soil vapor survey, the BFDESD, in its letter dated July 28, 1998, required 3 months of operation of the VES to reduce the potential migration of gasoline hydrocarbons into the thrift store building prior to considering the site for closure. During the first quarter of 1999, Saint Vincent De Paul obtained pre-approval of costs for active remediation from the SWRCB/USTCF. On April 21, 1999, HFA submitted an ATC permit/PTa application to the SJVUAPCD-SR for the installation and operation of an Emission Control Systems, Inc. (ECS) 250-scfm, thermal/catalytic oxidation unit. On June 9, 1999, the SJVUAPCD-SR issued ATC Permit #S-3548-1-0 for the installation and operation of an ECS thermal/catalytic oxidation unit at the site (see Attachment 2 for the ATC permit). From June 25, 1999, through July 2, 1999, HFA drilled and constructed seven vapor extraction wells (VW-1 through VW-7) at the site. The soil borings were positioned in a pattern designed to provide separate vapor extraction wells for the near-surface, highly permeable zone and for the deeper, moderalely permeable zone (see Figure 2 for vapor extraction well locations). During the third quarter of 1999, the VES unit was delivered to the site and connected to electricity and supplernental fuel as well as the vapor extraction wells, and start-up system ~ A Mr. Cliff Calderwood ~ HOLGUIN, .I~11. SJVUAPCD-SR ~ FAFLAN February 8, 2000- Page 4 ~ &/-M.q.SOCIATI_ZL$, INC. ENVII:qONMENq'AL MANAGEMENT CONSULTANTS lesling was performed (see Figure 3- VES Schematic Diagram and Figure 4 - VES Process Componenl Description). During the fourth quarter of 1999, full-time operation of the VES was initiated, tdFA has operated the unit 24 hours per day since start-up wi~h only short interruptions for periodic maintenance, draining of the knockout poi, and a few occurrences when the system has shut down. The concentration of the inlet was maintained between 350 and 950 ppmv (approximately 3.5 fo 9.5 percent of the LEL). With the gradual decrease in the concentration of the vapor extracted from the subsurface, the unit' has automatically introduced a flow of supplemental natural gas to maintain the temperature of the thermal oxidizer above the required set point of 1,400°F in compliance with Condition #21 of the ATC permit. Natural gas usage is averaging less than 0.1 MM Btu/hr, with the pilot flame consuming almost all of the natural gas flow. The inlet soil vapor flow rate has been maintained near the maximum contained in the ATC permit and consistently ranges from 150 to 225 cfm. During the December 21, 1999, inspection, the inlet soil vapor flow rate was measured at 170 cfm on the flow gauge of the VES unit, which was confirmed using a portable potentiometer. SOURCE STUDY SAMPLING METHODOLOGY On December 21, 1999, HFA personnel collected influent and effluent vapor samples in compliance with Condition #5 of the ATC permit. The source study consisted of obtaining vapor samples at the system influent and emission stack and submitting the samples for laboratory analyses. Vapor samples were collected using pre-cleaned, 3-liter TedlarTM bags. The bags were equipped with 0.25-inch TeflonTM tubing extensions for attachment to sampling ports on the VES piping. LABORATORY ANALYSIS Each vapor sample was analyzed by Zalco Laboratories, Inc., a California state-certified laboratory, for TPH as gasoline, BTEX, and MTBE. ANALYTICAL RESULTS A TPH as gasoline concentration was detected in the influent sample at 371 ppmv, but was not detected in the effluent sample. A benzene concentration was detected in the influent sample at 4.63 ppmv, but was not detected in the effluent sample. MTBE concentrations were not detected in the influent sample or the effluent sample (see Table 1 - Summary of Source Compliance Monitoring Analytical Results and Attachment 3 for the laboratory report).

ENVII:ZtONMEN3'-AL MANAGEMENT CONSULTAN'I'.?~ CONCLUSIONS Based on lhe vapor sampling and laboratory analytical results of the source study and the field monitoring since start-up, the source testing demonstrates compliance with Conditions #14 and #22 of the ATC permit since the control efficiency is greater than 95 percent, and the daily total VOC emissions do not exceed 2 pounds, HFA respectfully requests that the ATC permit status be upgraded to a PTO. The services performed by HFA were conducted in a manner consistent with the level of care and skill ordinarily exercised by members of its profession currently practicing under similar conditions in the state of California.
