BACKGROUND The Praxair facility is located on the west side of Pierce Road near the intersection with Orin Way. The Site is approximately l/2-mile north of the intersection of Highway 99 and Highway 58. The Site is an industrial gas distribution facility (Figure 2). In December 1987, a fuel leak was reported frorfi a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. The assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, Inc., (Uriah) was retained to install, develop, and sample groundwater monitoring wells. A total of eight monitoring wells were installed between October 1989 and June 1991. Laboratory analysis of samples collected from these wells indicated petroleum hydrocarbon concentrations as high as 18,000 /ag/L (MW-3, November 19, 1990) in groundwater. Groundwater levels in these wells dropped steadily for several years after the wells were installed. At the time of the last sampling event performed by Uriah in November 1991, the groundwater table elevation was below the bottoms of wells MW-1 through MW-6. Groundwater samples from deeper wells MW-7 and MW-8 contained no petroleum hydrocarbons in November 1991. Roux began quarterly groundwater sampling at the Site in June 1993. The groundwater table elevation was below the bottom of wells MW-1 and MW-5 in June 1993. Monitoring well MW-6 could not be located and appeared to have been paved over. Groundwater samples were collected in June 1993 from monitoring wells MW-7 and MW-8 and laboratory analysis of these samples indicated petroleum hydrocarbons were not present above method detection limits. PX29~O1W.3.20 Mr. Jo,: Lopcz Page 2 of:3 April 6, 1995 .. The groundwater table elevation rose about 14 ft. between the June and September 1993 quarterly groundwater sampling-events. Groundwater' samples collected in September 1993 from monitoring wells MW-l, MW-3 through MW-5, MW-7, and MW-8 were analyzed for total purgeable petroleum hydrocarbons (TPH-G) and benzene, toluene, ethylbenzene and total xylenes (BrEX). Monitoring well MW-2 was blocked about 12 in. from ground surface, not allowing a bailer to be lowered down the well. Laboratory analysis of those samples indicated petroleum hydrocarbons were present above method detection limits only in the groundwater sample collected from MW-3. Sample MW-3 contained concentrations of TPH-G at 87/~g/L, toluene at 1.5 ~g/L, and xylenes at 12 ~g/L. Based on the quarterly monitoring results from June 1993 to March 1994 the number of wells sampled each quarter was reduced from six wells to three wells (wells MW-3, MW-4 and MW-5). At the request of Dolores Gough of Kern County Environmental Health Services Department, wells MW-3, MW-5, MW-7 and MW-8 were sampled for this sampling event. SAMPLING PROCEDURES Four monitoring wells at the Site were ~mpled on March 15, 1995.' Prior to sampling, the water level elevation in each well was measured (Table 1). Groundwater samples were collected from the monitoring wells after three casing volumes of water had been purged from each well. Water samples were collected in a clean bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. WATER LEVEL MEASUREMENTS Depth to groundwater was measured on March 15, 1995, in seven monitoring wells at the Site. The groundwater elevations measured in monitoring wells MW-1 through MW-5, MW-7, and MW-8 ranged from 29.08 ft. to 29.96 ft. below ground surface Cogs) (Table 1). The water table elevation has risen approximately 2.25 ft. since December 21, 1994. Groundwater elevations calculated from the water levels in monitoring wells MW-I, MW-2, MW-3 and MW-5 indicate the direction of groundwater movement at the Site was to the west. The gradient varied between 0.011 and 0.006 (Figure 3). The groundwater elevations in monitoring wells MW-4, MW-7 and MW-8 were not used to determine the direction of flow and gradient. The groundwater elevation in well MW-4 was not used because the reading was anomalously high. The groundwater elevations in wells MW-7 and MW-8 were not used because these two wells are not screened across the water table. LABORATORY RESULTS Groundwater samples were analyzed by Zalco Laboratories, Inc., (Zalco) of Bakersfield, California, for TPH-G, and BTEX by USEPA Method 5030/8015/8020. A summary of the laboratory analytical data for groundwater samples collected at the Site in March 1995 is presented in Table 2. The laboratory analytical reports and Chain-of-Custody documentation forms for water samples are included in the Attachments. PX29901W.3.20 Mr. Jot Lopcz ])ago 3 of 3 April 6, [995 - Laboratory analyses of the groundwater samples collected from monitoring wells MW-3, MW-5, MW-7, and MW-8 indicated TPH-G and BTEX compounds were not present above method detection limits. TPH-G and benzene concentrations are also shown on Figure 4. No additional groundwater monitoring events are scheduled at this Site. REMEDIATION SYSTEM STATUS Soil remediation by soil vapor extraction commenced on December 9, 1993. On June 3, 1994, the vapor extraction system (VES) was shut down because the effluent vapor concentration from the first carbon filter had detectable levels of volatile organic compounds (VOCs). The first carbon filter was replaced and the system was restarted on August 4, 1994. Zalco conducted weekly field monitoring activities. Field monitoring activities included draining condensate from the system and measuring VOC concentrations of the extracted and treated vadose-zone vapors. Extracted vapor concentrations were not measured during this quarter but are estimated to be about 20 ppmv. On March 28, 1995, the carbon filters were removed by Wheelabrator Westates. A request to terminate the air permit was issued to the San Joaquin Valley Unified Air Pollution Control District (attached). The total estimated quantity of TPH-G removed by the remediation system during this quarter is estimated to be approximately 50 lbs. Total TPH-G removed to date is approximately 500 lbs. These mass removal quantities are based upon estimated VOC concentrations, vapor flow rates and hours of operation. Given the mass of carbon in the first filter (957 lbs), the carbon loading on March 28, 1994, was approximately 13% by weight. Respectfully ~ubmitted, ROUX ASSOCIATES, INC. Rick Riedl, P.E.

Based on our review, it appe~s that ~e site may be ready for closure. However, remediafion of ~e vadose zone needs to be verified by adv~cing a minimum of one confi~ato~ boring at ~e foyer ~nk location. ~e resul~ must be submiRed to ~is office wi~in 30 days from the sampling date. Following verification that the site has been remediated to ac~p~ble levels, the following need to be conducted before a closure le~er can be issued. 1. All the wells ins~lled for ~is investigation must be properly abandoned. 2. All remaining wastes such as soil cuEings and purged water generated from site activities must be disposed or recycled in accord~ce wi~ applicable laws and regulations. 3. ~e vapor extraction system must be dismantled and ~y resulting wastes disposed or recycled in accordance with applicable laws and regulations. ~e above are our minimum requirements for closure, hence we believe a meeting at ~is phase of the project may not be of benefit to either pa~.

Dear Ms. Gough: Enclosed you will find the First Quarter 1995 Groundwater Monitoring Report as prepared byour consultant ROUX ASSOCIATES. As you will note, and as I had previously communicated to you all wells sampled were NON-DETECTABLE. Also included in this package are the soil boring results that were taken on the same day that the monitoring well samples were taken. You will note that all soil samples taken from our confirmation boring were NON-DETECTABLE, as we had previously discussed. The last piece of information included in this package is a letter sent by ROUX ASSOCIATES to Mr. Tom Gofs from the San Joaquin Valley Unified Air Pollution Control District, in which we requested that our air permit to operate the Vapor Extraction System be terminated since we are closing the site. As per our agreement, I am in the process of securing the services of Advance Environmental Concepts Inc., for the purpose of closing the Pierce Road site, as per your instructions in your letter dated January 24, 1995. Mr. Joseph A. Dunwoody from AEC will be coordinating the efforts to close the site and will be contacting your office prior to abandonment of the wells so you can be present, if you wish. If you have any questions or concerns please feel free to contact me at (510) 866-6810. Respectfully yours, PRAXAIR INC. I o Joseph Lopez Project Manager cc: Mr. John Noonan C.R.W.Q.C.B. Mr. N.A.

BACKGROUND The Praxair facility is located on the west side of Pierce Road near the intersection with Ofin Way. The Site is approximately ½-rnile north of the intersection of Highway 99 and Highway 58. The Site is an industrial gas distribution facility (Figure 2). In December 1987, a fuel leak was reported from a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. The assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, Inc., (Uriah) was retained to install, develop, and sample groundwater monitoring wells. A total of eight monitoring wells were installed between October 1989 and June 1991. Laboratory analysis of samples collected t¥om these wells indicated petroleum hydrocarbon concentrations as high as 18,000 gg/L (MW-3, November 19, 1990) in groundwater. Groundwater levels in these wells dropped steadily for several years after the wells were installed. At the time of the last sampling event performed by Uriah in November 1991, the groundwater table elevation was below the bottoms of wells MW-1 through MW-6. Groundwater samples from deeper wells MW-7 and MW-8 contained no petroleum hydrocarbons in November 1991. Roux began quarterly groundwater sampling at the Site in June 1993. The groundwater table elevation was below the bottom of wells MW-1 and MW-5 in June 1993. Monitoring well MW-6 could not be located and appeared to have been paved over. Groundwater samples were collected in June 1993 from monitoring wells MW-7 and MW-8 and laboratory analysis of these samples indicated petroleum hydrocarbons were not present above method detection limits. PX29901W.3.20 Mr. Joe Lopcz Page 2 of 3 April 0. 1995 The groundwater table elevation rose about 14 ft. between the June and September 1993 quarterly groundwater sampling events. Groundwater samples collected in September 1993 from monitoring wells MW-l, MW-3 through MW-5, MW-7, and MW-8 were analyzed for total purgeable petroleum hydrocarbons (TPH-G) and benzene, toluene, ethylbenzene and total xylenes (BTEX). Monitoring well MW-2 was blocked about 12 in. from ground surface, not allowing a bailer to be lowered down the well. Laboratory analysis of those samples indicated petroleum hydrocarbons were present above method detection limits only in the groundwater sample collected from MW-3. Sample MW-3 contained concentrations of TPH-G at 87 #g/L, toluene at 1.5 txg/L, and xylenes at 12 ~g/L. Based on the quarterly monitoring results from June 1993 to March 1994 the number of wells sampled each quarter was reduced from six wells to three wells (wells MW-3, MW-4 and MW-5). At the request of Dolores Gough of Kern County Environmental Health Services Department, wells MW-3, MW-5, MW-7 and MW-8 were sampled for this sampling event. ..~ SAMPLING PROCEDURES Four monitoring wells at the Site were sampled on March 15, 1995. Prior to sampling, the water level elevation in each well was measured (Table 1). Groundwater samples were collected from the monitoring wells after three casing volumes of water had been purged from each well. Water samples were collected in a clean bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. WATER LEVEL MEASUREMENTS Depth to groundwater was measured on March 15, 1995, in seven monitoring wells at the Site. The groundwater elevations measured in monitoring wells MW-1 through MW-5, MW-7, and MW-8 ranged from 29.08 ft. to 29.96 ft. below ground surface (bgs) (Table 1). The water table elevation has risen approximately 2.25 ft. since December 21, 1994. Groundwater elevations calculated from the water levels in monitoring wells MW-l, MW-2, MW-3 and MW-5 indicate the direction of groundwater movement at the Site was to the west. The gradient varied between 0.011 and 0.006 (Figure 3). The groundwater elevations in monitoring wells MW-4, MW-7 and MW-8 were not used to determine the direction of flow and gradient. The groundwater elevation in well MW-4 was not used because the reading was anomalously high. The groundwater elevations in wells MW-7 and MW-8 were not used because these two wells are not screened across the water table. LABORATORY RESULTS Groundwater Samples were analyzed by Zalco Laboratories, Inc., (Zalco) of Bakersfield, California, for TPH-G, and BTEX by USEPA Method 5030/8015/8020. A summary of the laboratory analytical data for groundwater samples collected at the Site in March 1995 is presented in Table 2. The laboratory analytical reports and Chain-of-Custody documentation forms for water samples are included in the Attachments. PX2990 lW.3.20 Mr. Joe Lopcz P~ge 3 of 3 April 6. 1995 Laboratory analyses of the groundwater samples collected from monitoring wells MW-3, MW-5, MW-7, and MW-8 indicated TPH-G and BTEX compounds were not present above method detection limits. TPH-G and benzene concentrations are also shown on Figure 4. No additional groundwater monitoring events are scheduled at this Site. REMEDIATION SYSTEM STATUS Soil remediation by soil vapor extraction commenced on December 9, 1993. On June 3, 1994, the vapor extraction system (VES) was shut down because the effluent vapor concentration from the first carbon filter had detectable levels of volatile organic compounds (VOCs). The first carbon filter was replaced and the system was restarted on August 4, 1994. Zalco conducted weekly field monitoring activities. Field monitoring activities included draining condensate from the system and measuring VOC concentrations of the extracted and treated vadose-zone vapors. Extracted vapor concentrations were not measured during this quarter but are estimated to be about 20 ppmv. On March 28, 1995, the carbon filters were removed by Wheelabrator Westates. A request to terminate the air permit was issued to the San Joaquin Valley Unified Air Pollution Control District (attached). The total estimated quantity of TPH-G removed by the remediation system during this quarter is ...:; 5."(. estimated to be approximately 50 lbs. Total TPH-G removed to date is approximately 500 lbs. These mass removal quantities are based upon estimated VOC concentrations, vapor flow rates and hours of operation. Given the mass of carbon in the first filter (957 lbs), the carbon loading on March 28, 1994, was approximately 13% by weight. Respectfully submitted, ROUX ASSOCIATES, INC. Rick Riedl, P.E.

BACKGROUND The Praxair facility is located on the west side of Pierce Road near the intersection with Orin Way. The Site is approximately %-mile north of the intersection of Highway 99 and Highway 58. The Site is an industrial gas distribution facility (Figure 2). In December 1987, a fuel leak was reported from a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. Their assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, /nc., (Uriah) was retained to install, develop, and sample ground water monitoring wells. A total of eight monitoring wells were installed between October 1989 and ~'une 1991. Samples collected from these wells have shown petroleum hydrocarbon concentrations as high as 18,000/~g/L (MW-3, November 19, 1990) in ground water. Ground water levels in these wells dropped steadily for several years after the wells were installed. At the time of the last sampling event performed by Uriah in November 1991, the ground water table elevation was below the bottoms of wells MW-1 through MW-6. Ground water samples from deeper wells MW-7 and MW-8 contained no petroleum hydrocarbons in November 1991. Roux began quarterly ground water sampling at the Site in June 1993. The ground water table elevation was below the bottom of wells MW-1 and MW-5 in June 1993. Monitoring well MW-6 could not be located and appears to have been paved over. Ground water samples were collected in June 1993 from monitoring wells MW-7 and MW-8 and laboratory analysis of these samples indicated petroleum hydrocarbons were not present above method detection limits. PX2~901W.3.13 Mr. Joe Lopez Page 2 of 3 Januar~ 26r 1995 The ground water table elevation rose about 14 ft. between the June and September 1993 quarterly ground water sampling events. Ground water samples collected in September 1993 from monitoring wells lVlW-1, MW-3 through MW-5, MW-'/, and MW-8 were analyzed for total purgeable petroleum hydrocarbons (TPH-G) and benzene, toluene, ethylbenzene and total xylenes (BTEX). Monitoring well MW-2 was blocked about 12 in. from ground surface, not allowing a bailer to be lowered down the well. Laboratory analysis of those samples indicated petroleum hydrocarbons were present above method detection limits only in the ground water sample collected from MW-B. Sample MW-3 contained concentrations of TPH-G at 87/ag/L, toluene at 1.5/ag/L, and xylenes at 12/ag/L. Based on the quarterly monitoring results, from June 1993 to March 1994 the number of wells sampled each quarter was reduced from 6 wells to B wells. SAMPLING PROCEDURES Three monitoring wells at the Site were sampled on December 21, 1994. Prior to sampling, the water level elevation in each well was measured (Table 1). Ground water samples were collected from the monitoring wells after three casing volumes of water had been purged from each well. Water samples were collected in a clean bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. WATER LEVEL MEASUREMENTS Depth to ground water was measured on December 21, 1994, in seven monitoring wells at the Site. The ground water elevations measured in monitoring wells MW-1 through MW-5, MW-7, and MW-8 ranged from 68.16 ft. to 68.65 ft. below ground surface (bgs) (Table 1). The water table elevation has fallen about 3.5 ft. since September 7, 1994. Ground water elevations calculated from the water levels in monitoring wells MW-1 through MW-5 indicate the direction of ground water movement at the Site was to the west at a gradient of about 0.005 (Figure 3). The ground water elevations in monitoring wells MW-7 and MW-8 were not used to determine the direction of flow and gradient because these two wells are not screened across the water table. The lower relative water elevations in monitoring wells MW-7 and MW-8 indicated a downward component of ground water movement at the Site. LABORATORY RESULTS Ground water samples were analyzed by Zalco Laboratories, Inc., of Bakersfield, California, for TPH-G, and BTEX by USEPA Method 5030/8015/8020. A summary of the laboratory analytical data for ground water samples collected at the Site in December 1994, is presented in Table 2. The laboratory analytical reports and Chain-of-Custody documentation forms for water samples are included in the Attachments. Laboratory analyses of the ground water samples collected from monitoring wells MW-3, MW-4, and MW-5 indicated TPH-G and BTEX compounds were not present above method detection limits. TPH-G and benzene concentrations are also shown on Figure 4. PX2~OO1W.3.13 Mr. Joc Lopcz Page 3 of 3 January 26, 1995 The next quarterly ground water samples are scheduled to be collected and analyzed during March 1995. REMEDIATION SYSTEM STATUS Soil remediation by soil vapor extraction (SVE)commenced on December 9, 1993. On June 3, 1994, the VES was shut down because the effluent vapor concentration from the first carbon filter had detectable levels of VOCs. The first carbon filter was replaced and the system was restarted on August 4, 1994. Roux is conducting weekly field monitoring .activities. Field monitoring activities include draining condensate from the system and measuring volatile organic compound (VOC) concentrations of the extracted and treated vadose-zone vapors. Extracted vapor concentrations are shown on Table 3. The total estimated quantity of TPH-G removed by the first stage adsorber during this quarter is estimated to be 77 lbs. Total TPH-G removed to date is approximately 400 lbs. These mass removal'quantifies are estimated based upon measured VOC concentrations, calculated vapor flow rates and hours of operation. Given the mass of carbon in the first filter (957 lbs), the carbon loading on December 30, 1994, is approximately 8% by weight. Respectfully submitted, ROUX ASSOCIATES, INC.

Based on our review, it appears that the site may be ready for closure. However, rcmediation of the vadose zone needs to be verified by advancing a minimum of one con_fkmatory boring at the former tank location. The results must be submitted to this office within 30 days from the sampling date. Following verification that the site has been remediated to acceptable levels, the following need to be conducted before a closure letter can be issued. l. All the wells installed for this investigation must be properly abandoned. ~'/~, ~- 2. All remaining wastes such as soil cuttings and purged water generated from site activities must be disposed or recycled in accordance with applicable laws and regulations. ~ ~"-~--~-~.,~ 3. ,The vapor extraction system must bc dismantled and any resulting wastes disposed or recycled in accordance with applicable laws and regulations. Thc above are our minimum requirements for closure, hence we believe a meeting at this phase of the, project may not be of benefit to either party. We appreciate your cooperation regarding this matter and if you have any questions or need further details on our requirements, please call mc at (805) 861-3636.

Bakersfield, CA (Permit No. 050033) Dear Ms. Gough: First of all I would like to apologize for having had to cancel our two scheduled meetings this month. It is my hope that by first establishing a written dialogue of the purpose for wanting to meet with you, we can better plan to meet or eliminate the need for a meeting, based on your assessment of this letter and attachments. As you are well aware we have had the above mentioned site in one state of remediation or other related activity since 1987, and groundwater monitoring since 1989. As you recall in our meeting in May of 1993 we discussed that a timely resolution to this project would be in the best interest of Kern County and Praxair. Attached you will find a summary of our ground water monitoring actMty since October of 1989, also included in this summary is the results of our last round of quarterly sampling taken in December of 1994, (you will soon be getting the complete report). As you will note all wells monitored were Non Detectable in December. Monitoring well Number 3 has been ND for the last three quarters, and the last detectable amounts were 0.082 ppm of TPH-G and 0.0017 ppm of Xylene. Benzene has been Non Detectable for at least the last six quarters, the main constituent of concern. Based on these historical results good progress has been made, and I believe warrants a request for closure. The main reason for presenting this information for consideration for closure is that our consultant has requested that we, (Praxair) authorized additional expenditure of $75M, (see attached) to complete this project. To date we have spent a total of $165M on this project, plus $6.9M of County Over Site charges. Presently I do not feel justified in authorizing the additional $75M to gain a few more parts per million. What I would like from your office is a review of this information and consideration for my petition to close this site under Kern County guidelines now. An Atmosphere of Excellence I have committed to our consultant that I would give them an answer on there request for additional funding by the end of January 1995. Your imputes will greatly assist me in making this decision, and would greatly be appreciated. If you have any questions or concerns please call me at (510) 866-6810, if I'm not available please leave me a message. After reading this letter and reviewing the information, if you feel that a meeting would be beneficial please let me know, and I will make it a point to come to Bakersfield. Again, thank you for your cooperation and consideration of this request. Respectfully yours, PRAXAIR, INC. I. Joseph Lopez, R.E.A. Western Region Projects Manager CC: N.A. DiFranco W. J. Callahan W.

BACKGROUND The Praxair facility is located on the west side of Pierce Road near the intersection with Orin Way. The Site is approximately l/:-mile north of the intersection of Highway 99 and Highway 58. The Site is an industrial gas distribution facility (Figure 2). In December 1987, a fuel leak was reported from a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. Their assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, Inc., (Uriah) was retained to install, develop, and sample ground water monitoring wells. A total of eight monitoring wells were installed between October 1989 and June 1991. Samples collected from these wells have shown petroleum hydrocarbon concentrations as high as 18,000 ~g/L (MW-3, November 19, 1990) in ground water. Ground water levels in these wells dropped steadily for several years after the wells were installed. At the time of the last sampling event performed by Uriah in November 1991, the ground water table elevation was below the bottoms of wells MW-1 through MW-6. Ground water samples from deeper wells MW-7 and MW-8 contained no petroleum hydrocarbons in November 1991. Roux began quarterly ground water sampling at the Site in June 1993. The ground water table elevation was below the bottom of wells MW-1 and MW-5 in June 1993. Monitoring well MW-6 could not be located and appears to have been paved over. Ground water samples were collected in June 1993 from monitoring wells MW-7 and MW-8 and laboratory analysis of these samples indicated petroleum hydrocarbons were not present above method detection limits. P~9~1W.3.4 Mr. Joe Lopez Page 2 of 3 October 26. 1994 The ground water table elevation rose about 14 ft. between the June and September 1993 quarterly ground water sampling events. Ground water samples collected in September 1993 from monitoring wells MW-l, MW-3 through MW-5, MW-7, and MW-8 were analyzed for total purgeable petroleum hydrocarbons (TPH-G) and benzene, toluene, ethylbenzene and total xylenes (BTEX). Monitoring well MW-2 was blocked about 12 in. from ground surface, not allowing a bailer to be lowered down the well. Laboratory analysis of those samples indicated petroleum hydrocarbons were present above method detection limits only in the ground water sample collected from MW-3. Sample MW-3 contained concentrations of TPH-G at 87/~g/L, toluene at 1.5/~g/L, and xylenes at 12 t~g/L. Based on the quarterly monitoring results from June 1993 to March 1994 the number of wells sampled each quarter was reduced from 6 wells to 3 wells. SAMPLING PROCEDURES Roux personnel sampled three monitoring wells at the Site on September 7, 1994. Prior to sampling, the water level elevation in each well was measured using a Solinst water level meter (Table 1). Ground water samples were collected from the monitoring wells after three casing volumes of water had been purged from each well. Water samples were collected in a clean teflon bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. WATER LEVEL MEASUREMENTS Depth to ground water was measured on September 7, 1994, in seven monitoring wells at the Site. The depth to ground water measured in monitoring wells MW-1 through MW-5, MW-7, and MW-8 ranged from 27.86 to 28.97 ft. below ground surface (bgs) (Table 1). The water table elevation has fallen about 0.7 ft. since June 3, 1994. Ground water elevations calculated from the water levels in monitoring wells MW-1 through MW-5 indicated the direction of ground water movement at the Site was to the west at a gradient of about 0.006 (Figure 3). The ground water elevations in monitoring wells MW-7 and MW-8 were not used to determine the direction of flow and gradient because these two wells are about 20 ft. deeper than wells MW-1 through MW-5 and the current water levels are about 18 ft. above the top of the perforated intervals of these two wells. The lower relative water elevations in monitoring wells MW-7 and MW-8 indicated a downward component of ground water movement at the Site. LABORATORY RESULTS Ground water samples were analyzed by Sequoia Analytical Laboratories of Concord, California, for TPH-G, and BTEX by USEPA Method 5030/8015/8020. A summary of the laboratory analytical data for ground water samples collected at the Site on September 7, 1994, is presented on Table 2. The laboratory analytical reports and Chain-of-Custody documentation forms for water samples are included in the Attachments. Laboratory analyses of the ground water samples collected from monitoring wells MW-3, MW-4, and MW-5 indicated TPH-G and BTEX compounds were not present above method detection limits. TPH-G and benzene concentrations are also shown on Figure 4. I=IOUX.4~.SSCX~4t'I~ II, lC. {~ Px~o~w.3.4 Mr. Joe Lopez Page 3 of 3 October 26, 1994 The next quarterly ground water samples are scheduled to be collected and analyzed during December 1994. REMEDIATION SYSTEM STATUS Soil remediation by soil vapor extraction (SVE) commenced on December 9, 1993. On June 3, 1994, the VES was shut down because the effluent vapor concentration from the first carbon filter had detectable levels of VOCs. The first carbon filter was replaced and the system was restarted on August 4, 1994. Roux is conducting monthly field monitoring activities. Field monitoring activities include measuring volatile organic compound (VOC) concentrations with a flame ionization detector (FID), and taking vacuum and pressure readings for the SVE system. Field monitoring results are shown on Table 3. The total estimated quantity of TPHoG removed by the first stage adsorbe~"~-~iS.ng this quarter is estimated to be 9 lbs. Total TPH~G removed to date is approximately(328 lbs'. These mass removal quantities are estimated based upon measured VOC concentrati6ns-;~"ehlculated 201~&,,37,,._ flow rates and hours of operation. Given the mass of carbon in the first filter (957zl~e'.~.~O?, carbon loading on September 7, 1994, is approxi mately 1% by weight.

BACKGROUND The Praxair facility is located on.~ the west side of Pierce Road near the intersection with Orin Way. The Site is approximately ½-mile north of the intersection of Highway 99 and Highway 58. The Site is an industrial gas distribution facility (FigUre 2). In December 1987, a fuel leak was reported from a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. Their assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, Inc., (Uriah) was retained to install, develop, and sample ground water monitoring wells. A total of eight monitoring wells were installed between October 1989 and June 1991. Samples collected from these wells have shown petroleum hydrocarbon concentrations as high as 18,000/~g/L (MW-3, November 19, 1990) in ground water. Ground water levels in these wells dropped steadily for several years after the wells were installed. At the time of the last sampling event performed by Uriah in November 1991, the ground water table elevation was below the bottoms of wells MW-1 through MW-6. Ground water samples from deeper wells MW-7 and MW-8 contained no petroleum hydrocarbons in November 1991. Roux began quarterly ground water sampling at the Site in June 1993. The ground water table elevation was below the bottom of wells MW-1 and MW-5 in June 1993. MOnitoring well lViW-6 could not be located and appears to have been paved over. Ground water samples were collected in June 1993 from monitoring wells MW-7 and MW-8 and laboratory analysis of these samples indicated petroleum hydrocarbons were not present above method detection limits. PX29901W.3.2 Mr. Jo~ Lopcz Page 2 of 3 July 27, 1994 ~.. The ground water table elevation rose about 14 ft. between the June and September 1993 quarterly ground water sampling events. Ground water samples collected in September 1993 from monitoring wells MW-I, MW-3 through MW-5, MW-7, and MW-8 were analyzed for total purgeable petroleum hydrocarbons (TPH-G) and benzene, toluene; ethylbenzene and total xylenes (BTEX). Monitoring well MW-2 was blocked about 12 in. from ground surface, not allowing a bailer to be lowered down the well. Laboratory analysis of those samples indicated petroleum hydrocarbons were present above method detection limits only in the ground water sample collected from MW-3. Sample MW-3 contained concentrations of TPH-G at 87/~g/L, toluene at 1.5/~g/L, and xylenes at 12/~g/L. Based on the quarterly monitoring results from June 1993 to March 1994 the number of wells sampled each quarter was reduced from 6 wells to 3 wells. SAMPLING PROCEDURES Roux personnel sampled three monitoring wells at the Site on June 3, 1994. Prior to sampling, the water level elevation in each well was measured using a Solinst water level meter (Table 1). Ground water samples were collected from the monitoring wells after three casing volumes of water had been purged from each well. Ground water sample field data sheets are provided in the Attachments. Water samples were collected in a clean teflon bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. WATER LEVEL MEASUREMENTS Depth to ground water was measured on June 3, 1994, in seven monitoring wells at the Site. The depth to ground water measured in monitoring wells MW-1 through MW-5, MW-7, and MW-8 ranged from 27.13 to 28.31 ft. below ground surface (bgs) (Table 1). The water table elevation has fallen about 0.5 ft. since March 1, 1994. Ground water elevations calculated from the water levels in monitoring wells MW-I through MW-5 indicated the direction of ground water movement at the Site was to the west at a gradient of about 0.006 (Figure 3). The ground water elevations in monitoring wells MW-7 and MW-8 were not used to determine the direction of flow and gradient because these two wells are about 20 ft. deeper than wells MW-1 through MW-5 and the current water levels are about 18 ft. above the top of the perforated intervals of these two wells. The lower relative water elevations in monitoring wells MW-7 and MW-8 indicated a downward component of ground water movement at the Site. LABORATORY RESULTS Ground water samples were analyzed by Sequoia Analytical Laboratories of Concord, California, for TPH-G, and BTEX by USEPA Method 5030/8015/8020. A stimmary of the laboratory analytical data for ground water samples collected at the Site on June 3, 1994, is:.presented on Table 2. The laboratory analytical reports and Chain-of-Custody documentation forms for water samples are included in the Attachments. Mr. Joe Lopez Page 3 of 3 July 27, 1994 Laboratory analyses of the ground water samples collected from monitoring wells MW-3, MW-4, and MW-5 indicated TPH-G and BTEX compounds were not present above method detection limits. TPH-G and benzene concentrations are also shown on Figure 4. The next quarterly ground water samples are scheduled to be collected and analyzed during September 1994. REMEDIATION' SYSTEM STATUS Soil remediation by soil vapor extraction (SVE) commenced on December 9, 1993. The initial startup operation was performed during the month of December 1993. During startup, vapor grab samples were obtained and analyzed fOr TPH-G and BTEX. Roux is conducting monthly field monitoring activities. Field monitoring activities include measuring volatile organic compound (VOC) concentrations with a flame ionization detector (FID), and taking vacuum and pressure readings for the SVE system. Field monitoring results are shown on Table 3. The total estimated quantity of TPHoG removed by the first stage adsorber during this quarter is estimated to be 194 lbs. Total TPH-G removed to date is approximately 322 lbs. These mass removal quantities were estimated based upon measured concentrations of TPH-G, measured VOC concentrations, measured vapor flow rates and estimated hours of operation. Given the mass of carbon in the first filter (957 lbs), the carbon loading is 34% by weight. On the last site visit (June 3, 1994), the effluent vapor concentration from the first carbon filter had detectable levels of VOCs. The VES was immediately shut-down. The first carbon filter will be replaced and the system ~ill be restarted prior to the next sampling event. Respectfully submitted, ROUX ASSOCIATES, INC..

BACKGROUND The Praxair facility is located on the west side of Pierce Road near the intersection with Orin Way. The Site is approximately ¼-mile north of the intersection of Highway 99 and Highway 58. The Site is an industrial gas distribution facility (Figure 2). In December 1987, a fuel leak was reported from a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. Their assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, Inc., (Uriah) was retained to install, develop, and sample ground water monitoring wells. A total of eight monitoring wells were installed between October 1989 and June 1991. Samples collected from these wells have shown petroleum hydrocarbon concentrations as high as 18,000/zg/L (MW-3, November 19, 1990) in ground water. Ground water levels in these wells dropped steadily for several years after the wells were installed. At the time of the last sampling event performed by Uriah in November 1991, the ground water table elevation was below the bottoms of wells MW-1 through MW-6. Ground water samples from deeper wells MW-7 and MW-8 contained no petroleum hydrocarbons in November 1991. Roux began quarterly ground water sampling at the Site in June 1993. The ground water table elevation was below the bottom of wells MW-1 and MW-5 in June 1993. Monitoring well MW-6 could not be located and appears to have been paved over. Ground water samples were collected in June 1993 from monitoring wells MW-7 and MW-8 and laboratory analysis of these samples indicated petroleum hydrocarbons were not present above method detection limits. Doc #PX29901 W. 1.20 Mr. Joe Lopez Page 2 of 4 March .31, 1994 The ground water table elevation rose about 14 ft. between the June and September 1993 quarterly ground water sampling events. Ground water samples collected in September 1993 from monitoring wells MW-l, MW-3 through MW-5, MW-7, and MW-8 were analyzed for total purgeable petroleum hydrocarbons (TPH-G) and benzene, toluene, ethylbenzene and total xylenes (BTEX). Monitoring well MW-2 was blocked about 12 in. from ground surface, not allowing a bailer to be lowered down the well. Laboratory analysis of those samples indicated petroleum hydrocarbons were present above method detection limits only in the ground water sample collected from MW-3. Sample MW-3 contained concentrations of TPH-G at 87 ~g/L, toluene at 1.5 t~g/L, and xylenes at 12/~g/L (Table 2). SAMPLING PROCEDURES Roux personnel sampled six monitoring wells at the Site on March 1, 1994. Prior to sampling, the water level elevation in each well was measured using a Solinst water level meter (Table 1). Ground water samples were collected from the monitoring wells after three casing volumes of water had been purged from each well. Ground water sample field data sheets are provided in the Attachments. Water samples were collected in a clean teflon bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. WATER LEVEL MEASUREMENTS Depth to ground water was measured on March 1, 1994, in seven monitoring wells at the Site. The depth to ground water measured in monitoring wells MW-1 through MW-5, MW-7, and MW-8 ranged from 26.70 to 28.05 ft. below ground surface (bgs) (Table 1). The water table elevation has risen about 2 ft. since December 2, 1993. Ground water elevations calculated from the water levels in monitoring wells MW-1 through MW-5 indicated the direction of ground water movement at the Site was to the west at a gradient of about 0.008 (Figure 3). The ground water elevations in monitoring wells MW-7 and MW-8 were not used to determine the direction of flow and gradient because these two wells are about 20 ft. deeper than wells MW-1 through MW-5 and the current water levels are about 18 ft. above the top of the perforated intervals of these two wells. The lower relative water elevations in monitoring wells MW-7 and MW-8 indicated a downward component of ground water movement at the Site. LABORATORY RESULTS Ground water samples were analyzed by Sequoia Analytical Laboratories of Concord, California, for TPH-G, and BTEX by USEPA Method 5030/8015/8020. A summary of the laboratory analytical data for ground water samples collected at the Site on March 1, 1994, is presented on Table 2. The laboratory analytical reports and Chain-of-Custody documentation forms for water samples are included in the Attachments. Laboratory analyses of the ground water samples collected from monitoring wells MW-l, MW-4, MW-5, MW-7 and MW-8 indicated TPH-G and BTEX compounds were not present above method detection limits. Ground water sample MW-3 contained detectable concentrations of TPH-G at 82/~g/L, and xylenes at 1.7 txg/L. Benzene, toluene, and ethylbenzene were not ~#XlX~~ II~-.. {~ Doc #PX29901W. 1.20 Joe Lopez Pnge 3 of 4 Mnrch 31, 1~94 detected in the MW-3 sample (Table 2). TPH-G and benzene concentrations are also shown on. Figure 4. The next quarterly ground water samples are scheduled to be collected and analyzed during June 1994. REMEDIATION SYSTEM STATUS Soil remediation by soil vapor extraction (SVE) commenced on December 9, 1993. Present at the Site for the first day of operation were personnel from Roux, Zalco Laboratories, Inc. (7_.alco), and the San Joaquin Valley Unified Air Pollution Control District (APCD). The SVE system is in compliance with the conditions in the air permit issued by the APCD. The initial startup operation was performed between December 9 and December 15, 1993. Following the startup period, Roux conducted five follow-up field monitoring activities. Field monitoring activities included taking vapor grab samples and concentration readings with a flame ionization detector (FID), and taking vacuum and pressure readings for the SVE system. All vapor grab samples were analyzed by Zalco for total petroleum hydrocarbons (TPH), benzene, toluene, ethylbenzene, and total xylenes (Table 3). Field monitoring results are shown on Table 4. The quantity of petroleum hydrocarbons removed from the subsurface is based upon analytical and field monitoring results, vapor extraction rates, and the hours of operation. Figure 5 chronologically shows the total volume of product recovered. The total amount of product recovered to date is approximately 21 gallons. Figure 5 indicates that most of the product was recovered within the first week of operation. The total estimated quantity of VOCs removed by the first stage adsorber during operation from December 9, 1993, through March 1, 1994, is estimated to be 114 lbs. This mass removal quantity was estimated based upon measured concentrations of TPH, measured vapor flow rate and estimated hours of operation. Given the mass of carbon in the first filter (957 lbs), the carbon loading is currently 12% by weight. Respectfully submitted, ROUX ASSOCIATES, INC. Paul Supple Todd Ramsden, R.G.

BACKGRO~ The P~r facility is ]o~t~ on the west side of Pierce Road n~ the inters~tion with Way. ~e Sim is approximately %-mile no~h of the inter~fion of Highway 99 ~d Highway 58. The Site is an industrial gas distribution facility (Figure 2). In December 1987, a fuel leak was reported from a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. Their assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, Inc., (Uriah) was retained to install, develop, and sample ground water monitoring wells. A total of eight monitoring wells were installed between October 1989 and June 1991. Samples collected from these wells have shown petroleum hydrocarbon concentrations as high as 18,000 t~g/L (MW-3, November 19, 1990) in ground water. Ground water levels in these wells have generally dropped in the last two to three years. As of the last sampling event performed by Uriah in November 1991, the ground water table elevation was below the bottoms of wells MW-1 through MW-6. Ground water samples from deeper wells MW-7 and MW-8 contained no petroleum hydrocarbons in November 1991. Roux began quarterly ground water sampling at the Site in June 1993. The ground water table elevation was below the bottom of wells MW-1 and MW-5 in June 1993. Monitoring well MW-6 could not be located and appears to have been paved over. Ground water samples were Doc #PX29901W. 1.18 Mr. Joe Lol~z Page 2 of 3 lanuary 31, 1994 collected in June 1993 from monitoring wells MW-7 and MW-8 and laboratory analysis of these samples indicated petroleum hydrocarbons were not present above method detection limits. Roux performed quarterly ground water sampling at the Site in September 1993. The ground water table elevation rose about 14 ft. since June 1993. Ground water samples were collected from monitoring wells MW-l, MW-3 through MW-5, MW-7, and MW-8. Laboratory analysis of those samples indicated petroleum hydrocarbons were only present above method detection limits in the sample collected from MW-3. The MW-3 sample contained total purgeable petroleum hydrocarbons at 87 txg/L, toluene at 1.5 txg/L, and xylenes at 12 t~g/L. SAMPLING PROCEDURES Roux personnel sampled six monitoring wells at the Site on December 2, 1993. Prior to sampling, the water level elevation in each well was measured using a Solinst water level meter (Table 1). Ground water samples were collected from the monitoring wells after three casing volumes of water had been purged from each well. Monitoring well MW-2 was blocked about 12 in. from ground surface, not allowing a bailer to be lowered down the well. Ground water sample field data sheets are provided in the Attachments. Water samples were collected in a clean teflon bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. Ground water samples were analyzed by Sequoia Analytical Laboratories of Concord, California, for total purgeable petroleum hydrocarbons (TPH-G), benzene, toluene, ethylbenzene and total xylenes (BTEX) by USEPA Method 5030/8015/8020. A summary of the laboratory analytical data for ground water samples collected at the Site on December 2, 1993, is presented on Table 2. The laboratory analytical rePorts and Chain-of-Custody documentation forms for water samples are included in the Attachments. WATER LEVEL MEASUREMENTS Depth to ground water was measured on December 2, 1993, in seven monitoring wells at the Site. The depth to ground water measured in monitoring wells MW-1 through MW-5, MW-7, and MW-8 ranged from 28.90 to 30.51 ft. below ground surface (bgs) (Table 1). The water table elevation has risen about 4 ft. since September 14, 1993. Ground water elevations calculated from the water levels in monitoring wells MW-1 through MW-5 indicated the direction of ground water movement at the Site was to the west at a gradient of about 0.01 (Figure 3). The ground water elevations in monitoring wells MW-7 and MW-8 were not used to determine the direction of flow and gradient because these two wells are about 20 ft. deeper than wells MW-1 through MW-5. The lower relative water elevations in monitoring wells MW-7 and MW-8 indicated a downward component of ground water movement at the Site. LABORATORY RESULTS Laboratory analyses of the ground water samples collected from monitoring wells MW-l, MW-4, MW-5, MW-7 and MW-8 indicated TPH-G and BTEX compounds were not present Doc #PX29901W. 1.18 'Mr. Joe Lopez Page 3 of 3 January 31, 1994 above method detection limits. The ground water sample collected from monitoring well MW-3 contained detectable concentrations of TPH-G at 80/zg/L, toluene at 0.60/zg/L, and xylenes at 13 /zg/L. Benzene and ethylbenzene were not detected in the MW-3 sample. Table 2 summarizes the laboratory analytical data for the ground water samples. TPH-G and benzene concentrations are also shown on Figure 4. The next quarterly ground water samples are scheduled to be collected and analyzed during March 1994.

BACKGROUND The Praxair facility is located on the west side of Pierce Road near the intersection with Orin Way. The Site is approximately IA-mile north of the intersection of Highway 99 and Highway 58. The Site is an industrial gas distribution facility (Figure 2). In December 1987, a fuel leak was reported from a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. Their assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, Inc., (Uriah) was retained to install, develop, and sample ground water monitoring wells. A total of eight monitoring wells were installed between October 1989 and June 1991. Samples collected from these wells have shown petroleum hydrocarbon concentrations as high as 18,000 ~g/1 (MW-3, November 19, 1990) in ground water. Ground water levels in these wells have generally dropped in the last two to three years. As of the last sampling event performed by Uriah in November 1991, the ground water table elevation was below the bottoms of wells MW-1 through MW-6. Ground water samples from deeper wells MW-7 and MW-8 contained no petroleum hydrocarbons in November 1991. Roux began quarterly ground water sampling at the Site in June 1993. The ground water table elevation was below the bottom of wells MW-1 and MW-5 in June 1993. Monitoring well MW-6 could not be located and appears to have been paved over. Ground water samples were Doc #PX29901W. 1.15 Mr. Joe Lopez Page 2 of 3 October 25, 1993 collected from monitoring wells MW-7 and MW-8 and laboratory analysis of these samples indicated petroleum hydrocarbons were not present above method detection limits. SAMPLING PROCEDURES Roux personnel sampled six monitoring wells at the Site on ~~=l~i]~. Prior to sampling, the water level elevation in each well was measured using a Solinst water level meter (Table 1). Ground water samples were collected from the monitoring wells containing ground water after three casing volumes of water had been purged from each well. Monitoring well MW-2 was blocked about 12 in. from ground surface, not allowing a bailer to be lowered down /~...~ the well. Ground water sample field data sheets are provided in the Attachments. Water samples were collected in a clean teflon bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. Ground water samples were analyzed by Sequoia Analytical Laboratories of Concord, California, for total purgeable petroleum hydrocarbons (TPH-G), benzene, toluene, ethylbenzene and total xylenes (BTEX) by USEPA Method 5030/8015/8020. A summary of the laboratory analytical data for ground water samples collected at the Site on September 14, 1993, is presented on Table 2. The laboratory analytical reports and Chain-of-Custody documentation forms for water samples are included in the Attachments. WATER LEVEL MEASUREMENTS Depth to ground water was measured on September 14, 1993, in seven monitoring wells at the Site. The depth to ground water measured in monitoring wells MW-i, MW-2 through MW-5, MW-7, and MW-8 ranged from 33.23 to 35.40 ft. below ground surface (bgs) (Table 1). The water table elevation has risen about 14 ft. since June 4, 1993. Ground water elevations calculated from the water levels in monitoring wells MW-1 through MW-5 indicated the direction of ground water movement at the Site was to the north at a gradient of about 0.05 (Figure 3). The measuring point elevations for monitoring wells MW-7 and MW-8 are unknown. LABORATORY RESULTS Laboratory analyses of the ground water samples collected from monitoring wells MW-l, MW-4, MW-5, MW-7 and MW-8 indicated TPH-G and BTEX compounds were not present above method detection limits. The ground water sample collected from monitoring well MW-3 contained detectable concentrations of TPH-G at 87 ttg/L, toluene at 1.5 ~g/L, and xylene at 12 ~g/L. Benzene and ethylbenzene were not detected in the MW-3 sample. Table 2 summarizes the laboratory analytical data for the ground water samples. TPH-G and benzene concentrations are also shown on Figure 4. Doc #PX29901 W. 1.15 Mr. ~o¢ Lopez Pag~ 3 of 3 October 25, 1993 The next quarterly ground water samples are scheduled to be collected and analyzed during January 1994. REMEDIATION SYSTEM STATUS An Application for Authority to Construct Modification was submitted to the San Joaquin Valley Unified Air Pollution Control District (APCD) on June 8, 1993. Roux completed the design of the vapor extraction system for the Site during August 1993. Roux received the air permit from the APCD on September 8, 1993. Bid packages to construct the vapor extraction system were sent out to qualified contractors.

BACKGROUND The Praxair facility is located on the west side of Pierce Road near the intersection with Orin Way. The Site is approximately %-mile north of the intersection of Highway 99 and Highway 58. The Site is an industrial gas distribution facility (Figure 2). In December 1987, a fuel leak was reported from a 10,000-gallon gasoline underground storage tank. This tank was removed and a limited environmental site assessment was conducted by Krazan and Associates. Their assessment indicated that petroleum hydrocarbons associated with the 1987 fuel leak remained in the shallow subsurface. In 1989, Uriah, Inc., was retained to install, develop, and sample ground water monitoring wells around the former tank pit. A total of eight monitoring wells were installed between October 1989 and June 1991. Samples collected from these wells have shown hydrocarbon concentrations as high as 18,000/~g/1 (MW-3, November 19, 1990) in ground water. However, ground water levels in these wells have generally dropped in the last two to three years. As of the last sampling event in November 1991, the ground water table elevation was below the bottoms of wells MW-1 through MW-6. Ground water samples from deeper wells MW-7 and MW-8 exhibited no petroleum hydrocarbons in November 1991. SAMPLING PROCEDURES Roux Associates personnel sampled monitoring wells at the Site on June 4, 1993. Prior to sampling, the water level elevation in each well was measured using a Solinst water level meter Doc #PX29901W. I. 13 (Table 1). 'Ground water samples were collected from the monitoring wells containing ground water after three casing volumes of water had been purged from each well. Ground water sample field data sheets ~ provided in the Attachments. Water samples were collected in a clean teflon bailer and then transferred into two 40-milliliter Volatile Organic Analysis (VOA) vials. The vials were stored in an ice chest while in transit to the laboratory. Chain-of-Custody documentation was maintained for the samples. Ground water samples were analyzed by Sequoia Analytical Laboratories of Concord, California, for total purgeable petroleum hydrocarbons (TPH-G), benzene, toluene, ethylbenzene and total xylenes (BTEX) by USEPA Method 5030/8015/8020. A summary of the laboratory analytical data for ground water samples collected at the Site on June 4, 1993, is presented on Table 1. The laboratory analytical reports and Chain-of-Custody documentation forms for water samples are included in the Attachments. WATER LEVEL MEASUREMENTS Depth to ground water was measured on June 4, 1993, in seven monitoring wells at the Site. Monitoring well MW-6 could not be located and appears to have been paved over. The depth to ground water measured in monitoring wells MW-7 and MW-8 were 49.25 and 49.90 feet below ground surface, respectively. The other five monitoring wells (MW-1 through MW-5) were dry. LABORATORY RESULTS Laboratory analyses of the ground water samples collected from monitoring wells MW-7 and MW-8 indicated TPH-G and BTEX compounds were not present above method detection limits. Table 1 summarizes the laboratory analytical data for the ground water samples. The next quarterly ground water samples are scheduled to be collected and analyzed during September 1993.

As we discussed in our meeting our mutual goal is to ensure that site remediation work begins very soon at the above mentioned location. Again I would like to assure you that Praxair is committed to cleaning up the site, and with Roux Associates spear heading the effort I'm..confident it will be done in an expeditions manner. In an effort to capture some of the key issues discussed at our meeting I would like to provide a short summary, hopefully in sequential order: 1. You would like to have the vapor extraction system operational as soon as possible. 2. The site remains as a high priority to you due to intrusion into the groundwater. 3. You stated that you would like to see quarterly monitoring reports, which will be started by June 30, 1993. 4. Roux has committed that 45-60 days after receiving an Authority to Construct and Operate the vapor extraction system from the San Joaquin Valley Unified Air Pollution Control District, the system will be operational. A copy of the Air Permit. will be forwarded to your office. An Atmosphere of Excellence BAKERSFIELD, CA PAGE 2 m~AY 13, 1993 PRAJCAIR FACILITY 5. You have indicated that you want monitoring samples prior to the vapor's entering the first carbon unit. Roux has agreed. 6. After installation of the system you would like to be notified, and when the monitoring well's are to be sampled you would like to be notified two days in advance. Steve Anderson agreed to these arrangements. 7. You indicated that site closure is different from site to site, but for our site you indicated' that the scenario could be dependent on monthly analysis, with three months of non-detect, the system would then be turned off for a couple of weeks, then turned on and monitored, if we still have at non-detectable levels, a confirmation boring would be put in, and if everything looks acceptable we could then close. One of the main constituents of concern is benzene, which would have to be at or below the MCL of 1 ppb. Also you indicated that you weren't sure if we were located in a drinking water aquifier, you indicated that you might be able to get something to us in writing on the protocol for closure. 8. I indicated that all correspondence relating to the site should be forwarded to my attention, so as to ensure a timely response. 9. Steve Anderson mentioned that Roux would probably use a double bank of activated carbon in place of a catalytic oxidation burner. You indicated that this technology would be acceptable. Overall we had a very productive meeting in a short period of time, and it is our goal to move ahead as quickly as the system will permit. We will keep you posted on our progress, by way of a milestone chart that Roux Associates will put together. If you have any questions or concerns or if I~ve misstated any facts please contact me at (510) 866-6810, if I~m away from my desk please leave a voice mail, again thank you for your time and patience.

The report showed that no concentration of BTX&E and TPH(g) above the minimum reporting level was found from monitoring wells MW-7 and MW-8. The other six wells were dry. The report also described the physical condition of the wells as a result of the recent regrading and repaving at the site. A visit to the site confirmed Uriah's findings. The following summarizes our requirements to correct the situation: 1. An effort should be made to fix MW-3 and MW-5 such that no water or other materials can get in and the wells may be useful (if needed in the future). If this is not possible, then the wells have to be properly abandoned. 2. Replace the locks and whatever is necessary to maintain the integrity, of MW-7 and MW-8. 3. Locate MW-6 and check its condition along with MW-4. If these wells cannot be fixed, then they have to be properly abandoned and replaced (if necessary). Regarding remediation, we require that the quarterly groundwater monitoring be continued. If the analysis show no significant levels of gasolin~e contamination again, .we. recommend that remediation alternatives be re-evaluated. Vapor extraction may be a suitable alternative for the vadose zone. 2700 "M" STREET, SUITE 300 BAKERSFIELD, CALIFORNIA 93301 (805) 861-3636 FAX: (805) 861-3429 Mr. W.J.

The following summarizes the information presented in the report: 1. Two soil borings were drilled and completed into groundwater wells (MW-7 and MW-8), in June of this year. Groundwater was encountered at about 50 feet. 2. Analytical results indicated the presence of low levels of gasoline constituents in the soil at depths of 36.5 to 46 feet. Gasoline constituents over the drinking water standards established by the Department of Health Services and water quality goals set by the Regional Water Quality Control Board were also found in the groundwater despite the decline in the water table. 3. The hydraulic conductivity (K) of the water-bearing formation was determined by conducting slug tests using Hvorslev Method on both MW-7 and MW-8. The "K" values are 3.19 X 10 -s ft/sec for MW-7 and 3.77 X 10 -5 ft/sec for MW-8. 4. Remediation by pumping was simulated using SUTRA, a computer model for solute transport in the saturated - unsaturated zone. Pumping rates of 0.04 and 0.02 ft3/sec were assumed in the model. 5. Uriah, Inc., recommended aerobic biodegradation as the method to remediate the soil and groundwater contamination. 2700 "M" STREET, SUITE 300 BAKERSFIELD, CALIFORNIA 93301 (805) 861-3636 FAX: (805) 861-3429 W.J. Callahan October 9, 1991 Page 2 As mentioned in our March 20, 1991, letter, the "pump and treat" method to remediate groundwater is acceptable to this Department. However, the water treatment alternative must be capable of treating the water to the approved action levels. This aspect of the proposed system has to be addressed further. In addition, the disposition of the treated water has to be provided. Regarding the soil contamination, the treatment system/process still needs some clarification. The clean-up levels also need to be addressed. Please submit your response to our concerns as an addendum to the February 1991 Remedial Action Plan by November 18, 1991. Our other requirements on a remedial action plan such as a health and safety plan must also be addressed then. Please refer to the Kern County Handbook UT-35 on these requirements.

Uriah's proposal to install two additional groundwater wells by MW-3 and MP/-5 is acceptable to this Oepartment. DurinM the drilling, we require that soil samples be retrieved, field screened, and/or sent for laboratory analysis (as necessary) starting at 35 feet down to a depth just above the groundwater. Our reason for this requirement is to get information on the impact of the declining water table to the soil. The slug test using Hvorslev method is also acceptable and can be conducted following the installation of the new wells. After all the testing has been completed, the results shall be evaluated to determine if "pump and treat" is still necessary or if it is still the most appropriate and cost-effective alternative to remediate the groundwater. The well installation must be started by July 1, 1991. Enclosed is an application form for the additional wells. Please keep us informed on the schedule of all field activities. If you have any questions reMarding this matter. I can be reached at (805) 861-3636.

Dear Ms. Gough: Thank you for your letter of March 20, 1991 and your comments regarding portions of the Remedial Action Plan previously submitted by Uriah concerning treatment of fuel hydrocarbon contaminated soil and groundwater at the referenced site. In response to those comments, we wish to propose the following: 1) The groundwater monitoring wells installed by Uriah were constructed primarily for the purposes of plume definition and compliance monitoring. We agree that the significant lowering of the water table as a result of the continuing drought presents a barrier to the installation of a treatment system which requires a high rate of pumping. We wish to propose, therefore, that two additional 2"-diameter wells ~i~be installed in the area of existing wells MW-3 and MW-5. Each ~/'"'of the new wells would be advanced to a depth of between 50' and 55' below ground surface. Each well would contain 0.020 slotted PVC well screen installed at least 15.0' below the depth of the lowest water table measured during the year 1990. 2) That hydraulic conductivity of the impacted formation be determined within all existing wells using the Hvorslev Method. This method is represented by the formula: K= (r2 in [L/R])/(2LT0), where: K is the hydraulic conductivity. r is the radius of the well casing. R is the radius of the well screen. L is the length of the well screen submerged in groundwater. T0 is the time it takes for the water level to rise or fall to 37% of the initial change. 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 With the Hvorslev Method, the water level in a well is measured before extracting an additional, known volume of water. Immediately after the water is extracted, the water level in the well is again measured (with water level measurements taken at timed intervals). The height of the water immediately upon extraction (of water) is "h ". The height of the water after a period of time "t" is "h"? Data is plotted by computing the ratio h/h and plotting it versus time on semi-logarithmic paper. o SUTRA (Saturated-Unsaturated Transport), a computer program developed by the U.S. Geological Survey and the U.S. Air Force, will be used to simulate fluid movement and the transport of dissolved contaminants in the.subsurface. The model uses hydraulic conductivities, porosities, aquifer thicknesses, and contaminant concentrations determined from well logs, laboratory analyses, and/or field tests, along with the hydraulic gradient(s) as input parameters and employs a two-dimensional hybrid finite-element and integrated-finite-difference method to approximate the governing equations that describe the two interdependent processes that are simulated. ~/3) As specified, Wells MW-2 and MW-4 will not be used as injection sites. These wells were deemed appropriate for this purpose as the mos~t recent laboratory a~alyses_3_ndicated the water was free of contamination, however, as this is not acceptable, we would propose to determine a radius of influence for each well using the Hvorslev Method. The information thus obtained would then be used to develop alternative pumping strategies using SUTRA. Upon reviewing the resultant data, an appropriate injection-extraction format could be developed. This format would then be presented to the Hazardous Materials Management Program for review and comment. Thank you for your assistance to date. We trust that the information provided herein is an adequate response to your concerns. If, however, you require additional information, Dlease contact either of the undersigned at (415) 455-4991.

"~umo and ~reat" ~s an acceptable approach to remediate contaminated groundwater. However, for this specific site we need more information on the pumping system design to include but not limited to the input parameters for the SUTRA computer model and how these oarameters are determined. 2. Groundwater monitoring wells MW-3 and MW-5 have well screens of 20 feet each, from 20-40 feet for MW-3 and from 22-42 feet for MW-5. With the declining water table, (as of November 1990 water table is 38' below ground surface), the available drawdown is not adequate for these wells to sustain an effective pump and treat system. $. The use of MW-2 and MW-4 as injection wells is not allowed at ~his time. Anaiyticai data ~ndicated that the ~roundwater from these wells is contaminated. 4. The target clean-up levels for both soil and groundwater and the rationale for these levels must be provided. The proposed biotreatment method does not seem capable o~ treating the contaminated groundwater to drinking water standards. 2700 "M" STREET, SUITE 300 BAKERSFIELD, CALIFORNR% 93301 (805) 861-3636 FAX: (805) 861-3429 Mr. W.

The report confirmed the presence of gasoline contamination in the soil and groundwater beneath this property. The vadose zone plume has been adequately assessed but not the groundwater. Uriah, Inc. recommended quarterly monitoring of all the wells in order to determine the contaminant plume over time and to assist with the calibration of a model. They further recommended that if remediation becomes necessary, the soil and groundwater will be remediated using an in-situ bioremediation system. This Department concurs with Uriah's recommendation to monitor the wells on a quarterly basis at this time. After sufficient data is collected, we require that at least three appropriate remediation alternatives be evaluated for this site. The costs and risks associated with each alternative must also be discussed. We would like to remind you that all reports regarding this investigation must be submitted to this Department for our review and approval.

Sincerely, Dolores Gough Hazardous Materials Specialist Hazardous Materials Management Program DG:jg cc: Walter Floyd, Uriah Bob Turner, CVRWQCB Uriah Inc. An Environmental Services Company September 18, 1989 Ms. Dolores Gough Hazardous Materials Specialist Hazardous Materials Management Program Kern County Department of Environmental Health Services 2700 "M" Street, Suite 300 Bakersfield, CA 93301 RE: Site Characterization Proposal For 3505 Pierce Road, Bakersfield, CA (Permit ~050033) Dear Ms. Gough: I am in receipt of a copy of your letter to Mr. Sam Rohn dated September 5, 1989 concerning Uriah's proposal of May 22, 1989. The following is presented in response to your concerns: 1) In June, 1988, staff of Krazan & Associates, Inc. advanced a boring in the area of the underground fuel storage tank pit- the area believed to be adjacent to the source of the fuel hydrocarbon release. Analysis of the soils from this boring (MW-A) revealed contaminants in soil at a depth of twenty feet; however, no contamination was detected at a depth of fifteen feet. This suggests that the permeable sands, silty sands, and gravels encountered in the area allowed the contaminants to migrate downwards without significant sorption or lateral and transverse dispersion. This conclusion is further supported by data acquired at Krazan boring #B-1 which was located approximately fifteen feet to the northwest (in the presumed down gradient direction). Analysis of soil samples from this boring failed to reveal detectable levels of target contaminants The conclusion drawn from Krazan's work is that contaminants migrate down through the soil column to ground water without significant lateral migration and that it is, therefore, the groundwater which is the media likely to both contain the bulk of contamination and determine the pattern of significant migration. With this in mind, Uriah developed its proposal, 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 placing borings in a pattern which might reasonably be expected to intercept migrating contaminants realizing that groundwater gradient is believed to change seasonally. 2) Krazan & Associates presented and developed data concerning' im groundwater gradient on Pages 3, 4, 5, and 12 of their June 16, 1988 report. While additional work could be done to determine gradient at this time, the data t~us~cqulred would ~ikely be repetitious~ It is also proposed that a determination ~'o~-otne~'~qulzer characteristics (e.g. storage capacity, hydraulic conductivity/transmissivity) would be an unnecessary financial burden upon our client until such time as the primary aspects of the site characterization, i.e. the full assessment of the lateral and vertical extent of contamination and an analysis of the potential threats to groundwater, the environ- ment, and the public health and safety are determined. 3) Uriah was not provided with current groundwater monitoring well sampling data. Should there be no recent sampling of the well, and/or upon your request, the existing well will be sampled and analyses conducted in accordance with the protocol described within Uriah's proposal. 4a) If free product is present within groundwater samples acquired from the proposed borings and/or the existing ground water monitoring well, gasoline sensitive paste will be placed upon the graduated tape of an electronic water level meter. The tape will be lowered to a depth below the water surface, then withdrawn and the thickness of free product measured and recorded. The volume of free product brought to the surface is expected not to exceed two liters. This material would be transferred to amber glass sampling bottles, sealed, labeled, placed on blue ice and transported to a certified hazardous waste analytical laboratory for possible data acquisition concerning existing and potential chemical and biological degradation potentials. 4b) As indicated within Paragraph #2 within the Scope of Work section of Uriah's proposal, it is proposed that a grab water sample be collected from each boring using a clean bailer lowered down into the boring below the water surface. Should sloughing of soil from the walls of the boring(s) preclude direct acquisition of water samples, it is proposed that samples be acquired in accordance with one of the following alternatives: 1) Via bailer lowered through the hollow stem of the drilling auger. 2) Via bailer following the temporary placement of well casing within the bore hole. .~!~?)i; Via monitoring well should their placement prove necessary. Here, two appropriate borings would be converted to groundwater monitoring wells and the number of soil borings reduced in order to conform with budgetary constaints set forth for this project. Subsequent to its acquisition, each water sample would be transferred to two Volatile Organics Analysis (VOA) vials. These would be promptly sealed with teflon-lined screw caps, labeled, and placed on blue ice. It is requested that the decision for the conversion of selected soil borings be left to the discretion of the on site Uriah. staff professional in consideration of conditions encountered during the work described.

Approval of the w~rkplan cannot be granted until the following concerns are adequately addressed: 1. The rationale for the number and locations of soil borings (which will also be used for groundwater sampling) was not clearly described. 2. The method of determining aquifer characteristics such as hydraulic conductivity and groundwater gradient was not provided. 3. Will the existing monitoring well be sampled or utilized in the determination of groundwater gradient in this phase of the investigation? 4. Regarding the groundwater sampling methodology, the following must be addressed: a) the sampling/handling of free floating prcduct (if any) b) the method of retrieving a representative groundwater sample It is highly recommended that selected soil borings be completed to monitoring ~lls for better sampling, for determination of certain' aquifer characteristics and for use in-future/additional workthat may be reqp~red.

Ashland Fresno, CA 93726 Re: Groundwater Contamination detected at Baker's Welding and Supply, 3505 Pierce Rd., in Bakersfield, CA associated with a release from a 10,000 gallon underground fuel tank. Dear Mr. Pfister: The facility known as Baker's Welding and Supply, located at 3505 Pierce Rd. in Bakersfield, California, has completed an investigation which showed the presence of ppb levels of petroleum hydrocarbons in groundwater supplies beneath the facility. The foiiow~ng is a discussion of all work completed at this site: 1. Baker's Welding and Supply had one iO,0O0 gallon underground gasoline tank at their facility at 3505 Pierce Rd. in Bakersfield, California. The tank was t~ghtness tested a year ago. 2. A service station equipment company discovered fuel in the manway around the submersible pump on the tank on 12-28-87. They pumped the fuel out and removed some of the contaminated soil. They suspected that the fuel was leaking out of a union attached to the submersible pump. 3. A representative of the Kern County Health Department found fuel odors emitting from the manway which housed the submersible pump, when inspecting the facility. 4. The facility was ordered to repair the leaking union, and determine the lateral and vertical extent of contamination in the soil, around the tank. r31~TRI~T (31:: F lC. F .~ Bill Pfister September Page 2 5. The tank site was assessed utilizing one boring (B-l) and one monitoring well (MW-A). B-1 was sited east of the tank. MWA was drilled just north of the submersible pump. 6. Petroleum Hydrocarbons were detected in the soil retrieved from the monitoring well (20 feet below grade) and in the water sample retrieved from the well. The water sample contained 35.7 ppb Benzene, 33.9 ppb Toluene, 88.6 ppb Xylenes, and 615 ppb total purgeable hydrocarbons. A copy of the initial site characterization report was sent to the- regional board by Krazan and Associates. The underground fuel tank was removed on September 15, 1988, and four soil samples were retrieved beneath the tank to be analyzed for BTX and TPH. A copy of the lab results will be sent to your agency as soon as they are received. If you have any questions please feel free to call me at (805) 861-3636.

No. 88-023 Baker's Welding & Supply 3505 Pierce Road Bakersfield, California 93308 Attn: Mark Cooper RE: Underground Storage Tank Leak Site Characterization Proposal Gentlemen, SITE LOCATION Baker's Welding & Supply is a retail outlet for welding equipment, located on the west side of Pierce Road between Gilmore Avenue and Getty Street in Bakersfield, California. The facility lies along the Orin Way alignment and is within 1/4 1/4 G, Section 23 T29S R27E, Mount Diablo Base Line and Meridian. The facility consists of a steel building which is divided into retail, office, and warehouse space. Also located on the site are above-ground storage tanks for liquid propane, oxygen, nitrogen, argon, and an underground storage tank containing unleaded gasoline. A septic system is located east of the building. The remainder of the site is paved with asphaltic concrete. The property is surrounded by a six-foot chain link fence. Currently, the property is owned by Cooper and Bridges, 110 South Montclair, Bakersfield, California. SITE HISTORY Baker's Welding & Supply currently stores unleaded gasoline in a 10,000 gallon buried fuel storage Lank at their Pierce Road facility for use in their own vehicles. The tank is approximately 18 years old. On November 25, 198~;, Main Office: Fresno/Clovis ,, 3860 N. Winery · Fresno, California 93726 · (209) 291-7337 Bakersfield (805) 393-2343 [] Visalia (209) 625-8251 [] Merced (209) 383-3993 Page No. 2 Proj. No. 88-023 the underground storage tank was precision tested. The tank was found to be uncertifiable by a PeLto-tiLe system tightness test. After the leak was located and repaired, the fuel system passed a PeLto-tiLe line and tank tightness test. The contractor who repaired the line indicat, ed that the leak was minor in nature and that he felt that little product had been lost. At the beginning of December 1987, the employees noticed a sluggishness in the pumping of fuel from the unleaded storage Lank. On December 28, 1987, employees were unable to pump gasoline from the underground storage Lank. On the same day, fuel was discovered in the manway around Lhe submersible pump. The fuel, as well as a small amount of soil, was removed from the manway. Il was suspected that the fuel leaked from the union between the submersible pump and the Red .]acket Leak Detector. Reconciliation of inventory records indicate that between 200 and 600 gallons of fuel may have been lost. However, these values are approximate. The underground storage facility is not currently in operation pending results of this site characterization. SUBSURF ACE CONDITIONS The topography of the site is relatively level. The subsurface materials are composed primarily of unconsolidated material deposited by the Kern River and ils tributaries. These materials are generally composed of sands and silty sand. The 300-foo~. clay, which separates the confined aquifer from the unconfined aquifer in the Bakersfield area, is thought to extend under this site. The depth ~o groundwater below the si~e in September 1987 was approximately 20 feet. This groundwater depth was obtained from Well H5~3, which is adjacent ~o the Teamsters' Union Hail across the street from Baker's Welding & Supply. The depth to groundwater is Well H53 has been as low as 64 feet in the fall of 1976, and as high as 1/4 fee~ in September 1986. The groundwater gradient is from southeas~ Lo northwest, perpendicular to the Kern River. This information was obtained from the Kern County Water Agency's report on water conditions in improvement District #4, 1987. The groundwater level below Baker's Welding is highly variable and depends on the volume of water in the Kern River. The volume of water in the I<ern KRAZAN & ASSOCIATES Page No. :~ Proj. No. 88-02:~ River near the site is the sum of the flow measured aL the Ca]loway Weir plus the inflow from Turnout t//4. Recent. and projected flow rates for the Kern River are 'summarized in Table 1. A flow rate of approximately 1,500 acre-feeL aL the Calloway Weir is necessary for surface flow to occur in the Kern River at Highway 178. Based on the projected flow rates in Table l, the water level below Baker's Welding & Supply should drop through November 1988. Table 1: Flow in the Kern River Channel, Winter 1987 to Winter 1988 Month Callowa¥ Weir (AF) Turnout lib, (AF) Total (AF) Nov. 52 0 52 Dec. 3,360 1,588 /4,948 Jan. 4,010 0 4,010 Feb. 56 0 5~ Mar. 0 0 0 No flow projected until November 1988 SCOPE and METHODOLOGY The scope of the preliminary site assessment is limited to the area directly adjacenl to the underground storage tank. The purpose of the preliminary site assessment is to determine whether or not fuel constituents are present in the soils or groundwater beneath the underground storage tank. In order to investigate these potentials, the following methods would be employed: 1. One boring (B-l) would be advanced to a depth of from 20 to /40 feet directly north of the underground storage tank. Samples would be obtained from this boring at five foot intervals until groundwater was encountered. These samples would be screened utilizing an H-nu photoionization detector. If volatile hydrocarbons were detected in the soil by the H-nu meter, and groundwater is encountered above 40 KRAZAN & ASSOCIATES Page No. /4 Proj. No. 88-023 feeL~ then the boring would be developed into a 2-inch groundwater monitoring well. :Z. A second boring would be placed directly south of the product dispenser just east of the underground storage tank. Samples would be obtained from this boring aL five foot intervals Lo a depth of 20 feet. These samples would be screened utilizing a photoianizatian detector. 3. Selected soil samples from the borings would be analyzed for benzene, toluene~ xylenes, ethylbenzene~ and total petroleum hydrocarbons. Analysis would be performed by an analytical lab certified for such testing by [he State of California. i;O .0~.~.,i,¢1.~~ /4. If a well is installed, groundwater samples would be obtained from the monitoring well and tested for benzene~ toluene~ xylenes~ ethylbenzene~ and total petroleum hydrocarbons. 5. All exploratory soil borings would be made by means of hollow stem flight auger. ~;. Sampling would be conducted by means of pushing stainless steel tubes to obtain discrete samples (test method ASTMD _t587-86, "Thin-wall tube sampling of soils"). 7. Soils borings would be backfilled with a sand cement slurry. 8. Drilling returns would be barreled and stored onsite, pending results of chemical analysis. 9. A report would be prepared presenting the results of the field exploration and chemical analysis of soil samples encompassing all work accomplished in this phase of the investigation, as well as conclusions and recommendations based on these results. The report would also include a plot plan showing [he !oca~ion of all borings. Additional information on field and laboratory methodology is contained in l:he attached Appendix titled Methodology. A diagram of the proposed monitoring well is at[ached. If there are any quest'ions or if we can be of further assistance, please do not hesitate to contact our office.

MO[31LIZATION PROCEDURES Drill personnel shall coordinate all uite activities arid access with the project engineer al: least ten working days in advance. The project engineer shall coordinate with local agency authoritiea and shall comply with all applicable regulations and permitting procedures. Prior to initiating drilling and sa~npling, the following activities shall be accomplished: 1. All utilities and piping shall be accurately located, based on a method of accepted practice. 2. All drilling and sampling equip~nent ,~hull be ste~Jlll cleaned or washed with high pressure/high temperature water at tile beginning of each drilling operation. 3. Containers for storing contaminated soil cuttings and contaminated water shall be supplied by the project engineer as needed. All necessary permits and associated fees for conducting drilling activities, including, but not limited to easement, air quality, and well drilling permits, as needed, shall be obtained prior to drilling. SOIL BORING P~.QCEDUt-<ES Drilling should be acco~nl)lished witl~ a I~ollow stem, continuou.~ flight auger. Under no circumstances are drilling fluids of any type, or water, to be added to the boring during collection of soil samples. All borings shall be described in detail usin9 tile U~ified 5oil Classification System and shall be logged by a professional geologist, civil engineer, or engineering geologist who is registered or certified by tile State of California and who is experienced in tile use of the Unified Soil Ch~ssification System. A technician trained and expe,-ienced ir, tile use of the Unified Soil -2- Classification System who is working under the direct supervision of one 'of the professionals shall be deelned qualified to log borlngo provided the aforementioned professional reviews the logs and assumes responsibility for the accuracy and completeness of the logs. All samples shall be clearly marked showing facility's name, 8itc; boring numbers, depth where samples take~, sequence of sample as bottom-l, upper-2 and top-:}. Ground water and/or cuttings generated during the drilling operations should be disposed of in accordance with the requirements of the California State Department of Health Services and/or the local implementing agency. C. SAMPLING PROCEDURES 1. Soil Samplincj Procedures Soil samples would generally be obtained at five foot intervals as measured from the surface (see SOIL BORING PROCEDURES), however, no soil samples shall be taken in the saturation zone if ground water is encountered. Soil Samples shall be collected utilizing a modified California drive sampler (2 in. 1. D.) or stainless steel push tubes. Sample lines shall be brass or stainless steel tubes. A minimum of one sample tube is to be collected at each sampling depth and tubes shall be capped air tight with a!unfinum foil or Teflon, and plastic caps, sealed, labelled, and placed in an ice chest for storage and transport to a certified analytical laboratory. Temperature within the ice chest shall be maintained near 4 degrees Centigrade. Under no circumstances is water ice to be used width may melt arid result in sample submersion. The sample number of each sample shall be entered on a signed chain-of-custody form. The re~nainder of tl~e salnple Lubes a~d soil i~ tl~e ~ample barrel shoe shall be used to complete field analysis. At all sample depths, one or two field tests, as specified under FIELD TESTING PROCEDURES shall be performed to assess tile presence or abse~ce of hydrocarbon contamination in the soil. Between sample depths, the sample barrel, shoe and water barrel shall be steam-cleaned or washed with high pressure/high temperature water. Drying should be accotnplished with clean disposable paper towels, and dry sample equipment shall be placed in clean, disposable paper towel until needed for next sample depth. -3- 2. Water Samplin~l Procedure a. Sampling for Floating Free Product. The sampling of free product which may be floating on the aurfaee of the ground water shall not be performed until the well has been allowed to stablize for at least 2,/; hours after development or other withdrawal procedure. A sample shall be collected which is indicative of the thickness of floating product within the monitoring well. This may be accomplished by the use of a clear acrylic bailer which is designed to collect a liquid free sample al' the free product/ground water interface. A graduated scale on the bailer is helpful for determining the thickness of free product. b. Sampling for Dissolved Product. If less than one-fourth inch of free product is detected by the above method, then analysis for dissolved constituents shall be performed by tho following ~nethod: The well shall be purged by bailing or pumping to remove four to ten well volumes prior to ~mnpling, or until the discharge water indicates sL~bilizgliol~ of temperalure, conductJvity~ and pH. 1[ the well is evacuated before four to ten well volumes are removed, or stabilization is achieved, the sample shall be taken when the water level in the weJ[ recovers to approximately 80% of its initial water level. However, for wells where recovery is very slow~ the sample should be taken as soon as the water level is sufficient Lo recover a representative sample. 2) Following appropriate purging, sample of the ground water shall be obtained in a manner which reduces or elirnina[es the possibility of loss of volatile constituents from the sample. For collecting samples~ a gas-~cuLed positive di'~place~nent pump or a ~ubmersible pump is preferred. A '[eflo~ or sLeel bailer is acceptable. Peristalitie pumps or air-lift pumps shall not be used. 3) Water samples shall be collected in vials or other eontainer8 specifically designed to I)revm~t loss of volatile constituents from the sample. No headspace should be present in the sample container once the container has bee sealed. Samples shall be handled and preserved in accordance with the procedures and methods acceptable by the State and local jurisdictions. -4- D. FIELD TESTING PROCEDURES FOR HYDROCARBON CONTAMINATION At all sample depths) the soil and water shall be field tested for benzene concentration using a portable photoionization detector (PID). E. LABORATORY ANALYSIS Sample collection, preservation and analysis shall be performed in accordance with the procedures acceptable to the county and the Regional Water Quality Control Board requirements. The turn-around time for -~uch analysis shall not exceed fifteen working days. F. MONITORING WELLS 1. General. Monitoring wells shall be constructed if required in accordance with the following specifications. a. A boring of 8 inches dimneLer shall be drilled to a maximum depth of 40 feet and/or at least 25 feet into the saturation zone. Should an aquitard or clay layer of five feet or more be encountered at any point below the wa[er table, drilling shall be halted and the exces~ hole i~ to be backfilled with concrete and the monitoring well constructed in the overlaying aquifer. b. Drilling shall be accomplished with a hollow stern, continuous flight auger. Under no circumstances shall conventional mud-rotary drill~ be used. 2. Completion of Monitorinq WeLl a. Wells must be constructed of materials which will lea~t affect wa[er quality data, and be of sufficient durability to withstand deterioration. Acceptable pil)e con.J[ruction material~ include: Polyvinyl chloride, stainless steel or low carborm ~teel. These material~ shall be thoroughly cleaned and rinsed with water so a~ to be free from organic contamination. b. Casings should be threated or fitted with slip sleeves, however, organic sealants shall not be used. The well casing shall be cement grouted with an annular seal beginning from 2 feet above the perforation zone to the ground surface or subsurface vault, and an appropriate surface sealer applied to prevent local surface contamination. Well centralizers shall be used so that perforations, well screens, gravel pack and annular seals are properly centered within the borohole. c. Gravel Pack Over Well Perforation Zone. The well perforation zone shall be packed with appropriate sand or gravel to provide filtration capacity and prevent siltation fro the aquifier zone. It should be constructed with well-rounded materials (crushed materials are unacceptable), and washed clean of silt, dirt and all other foreign matter. The filtration zone should extend two feet above the top of the perforated zone. Placement of the -~and or gravel pack zone and proceed upward. Filter placement shall be conducted in such a manner Lo minimize the possibility of segregation. d. Annular Seal An un~ular sea[ should be placed above Ll~e zone of perforation and extend to the ground surface or subsurface containment vault. It shall be composed of neat cement, cement grou~, or concrete. If cement ia used, it shall be class A Portland Cement. In ca~e9 whore PVC ca~ing~ are u~ed [1~o la[o~lL heal of hydr~Lion should be monitored to prevent damage of premature failure of the ca~ing. The effect~ of latent heal can be minimized by the addition of bentonite or sand, or by si~nply allowing the mixture Lo cool before placement. A finer zone of material is required above the gravel pack to prevent seepage of sealer material. This layer should be composed of bentonite pellets. Sealer material should be thoroughly mixed with clean water, The materials shall be placed~ beginning from the bottom of the ~ealing interval~ in such a manner to prevent bridging~ dilution and segregation when placed underwater. If bentonite pellets are used for the seal~ placement can be through free fall as bentonite pellets would sink to tl~e bottom of any water which may have seeped into tt~e l~ole. Whe~ I~urtla~d ce~ne~t is used~ placement shall be in one continuous lift ~or the entire interval to be sealed. e. Well Bottom Plug~ The bottom of each well should be permanently sealed to prevent improper well development, siltation, or a cavity from forming at the base of the easing. Tlfi~ sl~ould be ~eeo~nplished with either a screw-on or friction cap, secured without the u~e of organic sealing compounds. f. Surface Security and Identification The platform or surface of each'well head shall be protected from all unauthorized entry, from fluids or va~dalism. Well heads may be secured above or below the ground de~ending on local surface conditions. Tile well hand 0hall bo healed with a waLer tight cap and be secured or looked. Well heads secured below the surface shall be vaulted, in a concrete or similar type vault, secured with a locking cover. The vault installation shall provide for drainage of accumulated ~urface run-off. £ach well shall be identified according to standard procedure~ including owner, well number, type of installation, and pertinent construction dale such as del)th, casing~ diameter~ and well screen perforation intervals. Well Development a. All monitoring wells shall be developed in order to clean the well and stabilize Lhe sand, gravel, and aquifier materials around the screens and perforaLions. Well developme~it may be accomplished by bailing~ surging or swabbing. Well development shall continue until the wall i~ thoroughly developed and free of sand~ silt and turbidity. b. If initial develop~nent pumping dewaLers tl~e wall casing and thereby inhibits development, clean, potable grade water can be Introduced into the well, followed by surgi~g of tho waters introduced with a swab or surge block. Care ~nust be taken not to damage the well screen or casing willie swabbing or surging. This is to be followed by pumping. The procedure should be repeated as required Lo establish full development. c. In the event a monitoring well cannot be completed as specified, abandon well by filling is in accordance with provisions set forth for abandonment of well ira Department of Water Resources Bulletin No. 74 and move drilling equipme~t Lo a new location. ~RN COUNTY HEALTH DEPARTME~mmm~r 1700 Flower Street AIR POLLUTION CONTROL DISTRICT LEON M HEBERTSON, M.D. Bakersfield, California 93305-4198 Director of Public Health Telephone (805) 861-3621 Air Pollution Control Officer January 28, 1988 Baker's Welding and Supply 3505 Pierce Road Bakersfield, California 93308 Attn: Mark Cooper Dear Mr. Cooper: A representative from this department made a site inspection of the underground tank facility, located at 3505 Pierce Road, in Bakersfield, California (Permit #050033C). The following information was obtained: 1. The unleaded fuel tank at the facility had been tightness tested a year ago. 2. Cal Valley discovered fuel in the manway around the submerged pump on the unleaded fuel tank on 12-28-87, at 2:45 P.M. They pumped the fuel out and removed some of the contaminated soil, placing tile soil on the asphalt near the manway cover. They suspected that the fuel was leaking out of a union attached to the submercible pump. They advised the manager to contact the Kern County Health Department. 3. The inspection by a representative of the Kern County Health Department revealed fuel odors emitting from the manway which housed the submercible pump for the unleaded fuel tank. The tank had been taken out of service and the area around the manway was roped off. Mark Cooper was called and the condition of the tank was discussed. The purpose of this letter is to describe what the facility is required to do in order to investigate the contamination plume, and repair the leak so that the tank may be returned to service. Baker's Welding and Supply Mark Cooper Page 2 January 28, 1988 1. The unleaded fuel tank must remain out-of-service until the leak is repaired and a receipt is presented to the Kern County Health Department, verifying the repair. 2. A site characterization proposal must be prepared describing how the lateral and vertical extent of contamination around the leak is going to be determined. The proposal must be submitted to this department within 30 days and approved before any work to characterize the site is initiated. The department's outline far preparation of the site characterization proposal is enclosed. It may be used as a guide in preparing the proposal. If you have any questions, please call me at (805) 861-3636. Sincerely, .~~~~~ Environmental Health Specialist ltazardous Materials Management Program AEG/gb aa~a,~Lw~o~os, .
