Shearer Kern County Superintendent Of Schools 1300 17th Street Bakersfield, California 93301-453.3 08-01385-002 RE: Underground Storage Tank Removal. 705 South Union Avenue, Bakersfield, California Dear Mr. Shearer: The following report by EnecoTech Southwest Inc. (EnecoTech) details the underground storage tank (UST) removals and associated activities conducted at the site located at 705 South Union Avenue, Bakersfield, California. Included as supporting documents are copies of the required permits, the i-insate hazardous waste manifest, and the laboratory reports. SITE DESCRIPTION The site is located on the west side of Union Street (Figure 1), and is used for vehicle maintenance, Superintendent administration, and various school equipment storage. Three 12,000-gallon USTs were located on the site prior to the tank removal activities. The removed tanks were numbered TI, T2, and T3, north to south, (Refer to Figure 2). Based on field observations, tank 1 contained unleaded gasoline, and tanks 2 and 3 contained diesel fuel. The removed tanks were composed of single walled fiberglass. The fuel lines extended to the north and east, connecting the USTs to the pump islands. The UST vent pipes extend west from the tank pit approximately 7 feet just west of the curb where they extended vertically up. o RccycJed Paper I I I I I I I I I I I I I I I I . ." ..-" -~~--_.....--=--~-=."

Lutrel Contractors also cut the concrete and excavated the soil above the old single walled fiberglass fuel lines. On August 5, 1997, EnecoTech's contractor, Advanced Cleanup Technologies Incorporated (ACTI) of Bakersfield removed the product lines. TANK REMOVAL On August 4, 1997, soil above the aforementioned USTs were excavated. On August 5, 1997, the USTs were triple-rinsed and any liquid in the tanks was removed. The tank contents and the cleaning rinsate (approximately 800 gallons) were pumped into a tanker truck contracted by ACT!. The uniform hazardous waste manifests for the pumped liquid is included in Appendix A. (A copies of the UST removal permit is included in Appendix B.) After being cleaned, dry ice was placed in each tank and then monitored for percent of lower explosive limit (LEL) and percent oxygen. The fire inspector then gave authorization and the tanks were removed from the excavation and crushed for placement in trash bins and later transport to a landfill. Tank removal and transport was performed by ACT!. Steve Underwood of the Bakersfield Fire Department (BFD) was present as the fire inspector during the tank removal and directed EnecoTech regarding the soil sample location. No holes or cracks were observed in the tanks during the removal process. The fuel lines appeared to be in good condition, with no obvious holes or damage. The fuel line and UST areas was not backfilled because Lutrel Contractor was installing new fuel lines, dispensers, and USTs in the excavations. ~ EnecoTech® ENVIRONMENTAL CONSULTANTS ~'. ;.., '.,'- "-;-;~~"'''''·."'':".i~''':; ,,:.,,-..;!;..- '~'~;""''::-.......¡;tii.~;',·.--i:i:~.·~:,·;¿,¡;;);~",;.....

Soil samples were collected from the both ends and the middle of each UST. Soil samples were collected from depths of 2 feet and 6 feet below tank bottom from each collection location. The bottom of the tanks are estimated to have been approximately 12 feet below ground surface. For consideration of safety. samples from beneath the USTs were collected with the aid of a excavator. A clean brass tube was inserted into the center of the soil by hand. The soil samples collected from below the USTs were designated ETI-2, MTI-2, etc... The first letter represents the position beneath the tank of east, middle, or west. The second letter and first number represent the tank number (Tank 1 = Tl). The last number represents the depth of collection below the tank. Soil samples, designated DI-5, DI-9, D2-5 etc... were collected from beneath the previous fuel dispenser locations. Soil samples PI-5 and PI-9 were collected from beneath the fuel lines located just west of dispenser D4. The fire inspector required that PI-5 and PI-9 be collected because this area was noticed by ACTI employees to have soil staining and odor during fuel line removal. A clean brass tube was pounded into the soil and sealed with teflon tape and plastic caps. The first letter and number of the dispenser sample IDs represent the dispenser number (Dispenser 1 = Dl). The last number represents the depth of collection below ground surface (bgs). The fuel lines were approximately 3 feet bgs throughout the site. Therefore, a soil samples designated DI-5 and DI-9 were collected from 2 feet and 6 feet below the fuel lines respectively. EnecoTech personnel followed the direction of Inspector Steve Underwood of BFD with resect to where all the samples were to be collected from and which analyses would be conducted on the samples. All soil samples were stored in a chilled ice chest and delivered to Advanced Technology Laboratories (ATL) of Signal Hill, California, a State-certified laboratory (# 1838).

Additionally, 22 of the soil samples were analyzed for total petroleum hydrocarbons as diesel (TPHd) using U.S. EPA Method 8015 modified. Laboratory results are presented in Table 1. and the laboratory reports and chain-of-custodies are included as Appendix C. The analytical results for the eighteen soil samples collected from beneath the tanks for TPHg ranged from not detected (less than 1.0 milligrams per kilogram (mg/kg)) to 5.6 mg/kg. The twelve soil samples from beneath T2 and T3 were analyzed for TPHd as well, and the results for each were reported as not detected (less than 10 mg/kg). Benzene was detected only in soil sample MT2-2 at a concentration of 0.0055 mg/kg. The analytical results of the eight soil samples collected from below the previous dispenser locations for TPHg ranged from 9.0 mg/kg to 1,560 mg/kg. The analytical results of the eight soil samples collected from below the previous dispenser locations for TPHd ranged from 42 mg/kg to 19,000 mg/kg. Each of the eight soil samples collected from below the previous dispenser locations were analyzed for BTEX. Benzene was detected only in soil sample Dl-5 at a concentration of 0.063 mg/kg. The analytical results of soil samples Pl-5 and Pl-9 collected from below the previous fuel1ines located just west of D4 for TPHg were reported as 1.2 mg/kg and not detected respectively. The analytical results of the soil samples Pl-5 and Pl-9 for TPHd were both reported as not detected. Both of the soil samples Pl-5 and Pl-9 were analyzed for BTEX. Benzene, toluene, ethylbenzene, and total xylenes were each reported as not detected. ~ EnecoTech® ENVIRONMENTAL CONSULTANTS . _. . ,-, ..n _..L...., _ ,..,..... __... _' ._ ~.

Concentrations of TPHd and TPHd below dispenser D 1 were both above 100 mg/kg in soil sample Dl-5 but were reported well below 100 mg/kg in Dl-9. Since Dl was the gasoline dispenser, it appears that the only significant compound of concern in the soil is diesel. Soil samples collected from below the USTs indicated that TPHd was not detected beneath the two diesel tanks and the highest TPHg detected beneath the three tanks was 5.6 mg/kg. Therefore, significant concentrations were not detected beneath the three USTs. EnecoTech has been instructed by Kern Superintendent of Schools to prepare a site assessment work plan to evaluate the vertical and horizontal extent of soil impact in the areas of D2, D3, and D4.

The report summarizes an investigation of an area of the site where a former release of diesel fuel had occurred. Following the advancement of seven borings in the vicinity of the on site dispenser pumps, samples were analyzed for TPHd and BTEX. Results indicate that the release area was apparently very localized and has not impacted the soil surrounding the fuel dispensers.

Three 12,OOO-gallon USTs were located on the site prior to tank removal activities which commenced on August 4, 1997. Following excavation of the tanks, they were triple-rinsed and pumped clean. Dry ice was then placed in each tank which was subsequently monitored for percent lower explosive limit (LEL) and percent oxygen. Tank removal was performed by Advanced Cleanup Technologies Incorporated (ACTI) of Bakersfield. Upon removal, no holes or cracks were observed in the tank by EnecoTech personnel. The fuel lines also appeared to be in good condition, with no obvious holes or damage. Eighteen soil samples were collected from the bottom of the UST graves on August 5, 1997 at depths of 2- feet and 6-feet. In addition. samples were collected from beneath the previous fuel dispensers. All sample locations and analyses completed were determined in conjunction with the on-site Bakersfield Fire Department representative, Inspector Steve Underwood. , ~ I I I I I I I I I I I Each of the samples (total of 28) collected was analyzed for total petroleum hydrocarbons as gasoline (TPHg) and benzene, toluene. ethylbenzene, and total xylenes (BTEX) using U.S. EPA Method 8015M and 8020 respectively. In addition, 22 of the soil samples were analyzed for total petroleum hydrocarbons as diesel (TPHd) using U.S. EPA Method 8015M. Analytical results for eight soil samples collected from below the previous dispenser locations for TPHg ranged from 9.0 mg/kg to 1,560 mg/kg. Concentrations of TPHd for these samples ranged from 42 mg/kg to 19,000 mg/kg. Only one sample of the eight was found to contain any detectable BTEX compounds; Dl-5 contained 0.063 mg/kg benzene. 1\vo samples which were collected from beneath the former fuel lines were not found to contain detectable levels ofTPHd or BTEX. One sample contained 1.2 mg/kg TPHg whereas the other did not contain a detectable concentration of TPHg. , ~ ~- Ú k ~; Based on the field observations and analytical results, EnecoTech concluded that petroleum hydrocarbons are present in the soil at significant levels in the areas surrounding the diesel fuel dispensers. Significant concentrations of TPH were not detected beneath the former USTs. - 4.2 Regional Geology The subject site is located in the Southern San Joaquin Valley. This area is bound by the southern portion of the Sierra Nevada Mountain Range to the east, the Transverse Ranges and the Tehachapi Mountains to the south, and the southern portion of the coast ranges to the west. The general topography of the Bakersfield region consists of alluvial terraces, fans, benches, and floodplains sloping westward from the foothills of the Southern Sierra Nevada Mountains to the main drainage axis of the San Joaquin Valley. The Kern River, a perennial stream draining an extensive watershed in the southern Sierras, flows in a generally southwestern direction through 4-2 o Recycled Paper EnecoTech® ., ENVIRONMENTAL CONSULTANTS - '" " ~ !l. .._ &.~.

Temperatures in this region average 57 degrees Farenheight in the winter and 90 degrees in the summer months. Annual average precipitation ranges between 4 and 6 inches. with most rainfall occurring between November and April. The San Joaquin Valley is a large basin lying between the Sierra Nevada range to the east and the coastal ranges to the west. The basin was fonned in intennittent westerly tilting of the underlying Mesozoic crystalline rocks. which elevated the Sierra Nevada and depressed the western portion of the block. During Tertiary and Quaternary periods. both marine and non-marine sediments were deposited on the basement rocks as the western portion was depressed. The Tertiary rocks consist of a series of stratified sediments including sandstones. conglomerates and shales that are relatively thin along the eastern margin and become increasingly thicker towards the southwest. Tertiary sediments are overlain by Quaternary sediments of varying thicknesses including Pleistocene non-marine terraces and fans. and Holocene fans and alluvium. During the late Pli~cene and early Pleistocene. the ancestral Kern River deposited a huge alluvial fan which spread for many miles in what is now Bakersfield. Subsequent uplift of the Sierra Nevada raised the fan to its current elevation. Erosion by the Kern River and its seasonal tributaries have produced the topography of the region. Local groundwater is generally found in shallow alluvial sediments of Holocene age. normally in unconfined aquifers. frequently becoming semi-confined with depth. Beneficial uses of groundwater in the area include agriculture. municipal. and industrial applications. Groundwater in the area was measured by the Kern County Water Agency in November 1992 at depths of 186 feet below the ground surface. Groundwater flow in the local area is to the northwest (Haslebacher. 1993). t f ¡. - ~ F f , ~ 4.3 Boring Advancement Proceedures and Analytical Results Borings were advanced on October 29. 1997 by EnviroProbe of Anaheim. California. A Geoprobe 5400 was used and as a result little soil waste was generated. The small amount of waste was collected in a 5-gallon bucket and amounted to approximately 1.5-gallons. EnviroProbe transported this soil off-site for disposal as non-hazardous waste. All PID readings indicated that the soil did not contain significant concentrations of volatile organic compounds; none of the waste or samples exhibited visual or olfactory evidence of contamination. Three samples from each of the seven borings were submitted to a state certified laboratory for the following analyses: Total Petroleum Hydrocarbons as diesel (TPHd) by the DHS-approved EPA Method 80 15M and benzene. toluene. ethylbenzene and xylenes (BTEX) using EP A Method 8020. Results are summarized below and presented in tabular fonn in Table 1. The laboratory report and chain of custody are included as Appendix C. None ofthe samples analyzed contained concentrations ofTPHd above the method detection limit. Furthennore. none of the soil samples contained detectable levels of benzene. toluene. ethylbenzene or xylenes. 4-4 o Recycled Paper EnemTech® ENVIRONMENTAL CONSULTANTS -'. .:_::;.".- -...._-'.>.'.'.-.:.

Ii ~:, I I I Previous sampling activities conducted at the site have identified the presence of petroleum hydrocarbons and chlorinated hydrocarbons in the soil and ground water beneath and adjacent to the facility. Site investigation activities are not expected to expose field personnel to potentially hazardous levels (greater than pennissible exposure level) of any hazardous substances anticipated to be present at the site. Chemical compounds detected during previous field work at the site included petroleum hydrocarbons as gasoline and diesel fuel(. Material safety data sheets for these compounds are provided in Appendix B. Table 1 identifies health hazard qualities associated with these hazardous substances. I Field personnel will employ safe techniques and protective measures to avoid overexposure to these· materials which may be present in the soil or ground water during site activities. High exposures to petroleum hydrocarbons and chlorinated hydrocarbons have been associated with various human blood disorders. liver disorders. nervous system disorders and an increased risk of cancer. When high concentrations are inhaled. symptoms of intoxication may result. Skin and eye irritation. potentially severe. may also result from contact with these chemicals. Every effort will be made to prevent contact of materials with the skin. eyes and/or mouth during site investigation activities. The use of gloves and safety glasses will prevent exposure to these compounds; mandatory washing and designated eating/drinking areas will further minimize the risk of chemical exposure. In the event of contact. soap and water will be used for the removal of materials from the skin. ~;: I I I ~; ~: ~ ,.::" ~[ ~~~ I:; f~ f ~ I 4.3 Potential Physical Hazards ~ ø t:Y.: -j. ~ " þ. The primary physical hazard anticipated during site investigation activities involves working in close proximity with the drill rig. The area around the auger will be cleared prior to drilling. and all site workers will remain clear during the drilling operation. Other physical hazards may include the following: ~\ .~: . .. I I I · Striking injuries during use of tools or equipment; · Slips. trips or falls; · Strains while digging. or while lifting equipment or materials; · Irritating noise levels; · Thennal stress; and · Electrical hazards posed by underground or overhead lines. '.--- ~. ., , .~ -.'# :.'. ~r I I I I Protection from physical hazards will be provided through standard safety procedures including good housekeeping. Field personnel will be briefed on proper lifting techniques. and will seek assistance when lifting/moving heavy objects. The hazards associated with excessive noise during these proposed site investigation activities are expected to be minimal. however. protection against any such effects will be provided as necessary. When biological hazards are discovered. personnel shall attempt to avoid contact and seek first aid if bitten or stung. Any personnel that have an allergic reaction to insect bites. etc.. shall seek medical attention immediately. Field team members shall consult with Karen Bridges. Site Safety Officer, about the location of underground electrical lines prior to drilling. ;:::" (; ~}: ~~i ::-~' ,'. ,. '. ~. .: ..

Operating procedures to minimize fIre and explosion hazards shall be implemented at all times, including bonding and grounding for the prevention and discharge of static electricity, -, :'~- , " .,' " 4.5 ,',J' ::-:' ,..... Thermal (Heat or Cold) Stress Due to the potential variability of weather conditions and the effects of protective outerwear decreasing body ventilation, there exists an increase in the potential for heat or cold stress, All fIeld personnel should be aware of the signs of heat stress, including cold, pale or clammy skin, fatigue or faintness, headache, nausea, weak pulse or heavy sweating. Initial signs of cold stress involve a tingling or numbing sensation in the outer extremities and can lead to loss of body heat (hypothermia) and/or frostbite, The SSO will be responsible for being aware of the conditions of field workers regarding thermal stress and dehydration, and for appropriate first aid response activities should they be necessary. Workers will be encouraged to take frequent rest and water breaks when working in hot weather. ",' 1:.;,;' ':', ;-".-, " '.. ., ;', I~ ': I .., !:.:. ',.. 4-2 o Recycled Paper EnecoTech® ''',.

Also, air monitoring of the work area will be conducted during the entire investigation process. Air morutoring procedures will include periodic monitoring (at a minimum of every 30 minutes during drilling and sampling activities) to identify and quantify airborne levels of volatile organic substances. A photoionization detector (PID) shall be used to monitor concentrations of organic vapors in the worker's breathing zone. and respirators will be used if the PID detects a reading greater than 5 ppm above background sustained for a 15-minute period. Full-face, air-purifying respirators (with high efficiency dust/organic vapor cartridges) will be worn if sustained organic vapor readings between 5 ppm and 50 ppm are detected. If monitoring indicates readings in the breathing zone greater than 50 ppm above ambient, site investigation activities will cease and the Project Manager and Corporate Health and Safety (CHSO) will be contacted. Engineering controls (i.e., exhaust fans) will be employed if necessary to reduce the vapor concentration in the worker breathing zone. Work will not begin until obtaining approval of these individuals.

SCOPE OF WORK To accomplish the stated objective, EnecoTech proposes to drill and collect soil samples from seven (7) soil borings to a depth of 30 feet below ground surface (bgs). The soil samples will be selected for analysis based on the field observations and photoionization detector (PID) readings for each sample. The proposed boring locations are subject to the location of underground utilities. !,;:.- f~"\ ~r.·.' &~ r' ~\! ~\ '~~ --'..' ~~ -, .::"~ t? ~.;,. The tentative locations of the soil borings are indicated in Figure 2. Drilling and sampling activities will be conducted under the supervision of a California Registered Geologist. Each soil boring '\vill be backfilled with bentonite chips or a bentonite grout mixture and sealed at the top with concrete. Soil cuttings from drilling operations will be placed in labeled Department of Transportation (DOT) approved 55-gallon drums and stored on the site. ,. F:i ,:' :.~ ,. EnecoTech will notify Underground Service Alert and the City of Bakersfield Fire Department 48 hours prior to any field activities. <"~I ': I :-1 c." 1 ;;'1 1 I Rtc:ftir Recycled Paper ~;., ~ .

All sampling equipment will be wåshed before sampling in. a A1conox (soap) solution and thoroughly rinsed. Based on th"e'results of the PID on each sample interval, a minimum of three soil samples from . . each boring will be analyzed. The geologist in the field will use the remaining recovered . ~ sample to descIibe tJ].e soil in accordance with the Unified Soil Classification System . (USCS). Additionally, a qualitative characteIization of contamination will be made based . upon any petroleum hydrocarbon odors or soil discoloration. These observations and USCS descIiptions will be included in the BoIing Logs, which will be reviewed by a California Registered Geologist. 5.0 ANALYTICAL PROCEDURES Each soil sample will be hand delivered to a on site State-certified hazardous waste testing laboratory. Three to four samples from each soil boring will be analyzed for Total Petroleum Hydrocarbons as diesel (TPHd) by the DHS-approved EPA Method 8015m; and BTEX using EPA Method 8020. The laboratory reports for soil sample results will be included in the Site Assessment Report. 6.0 REGIONAL GEOLOGIC/HYDROGEOLOGIC SETTING 6.1 Regional Physiographic Conditions The subject site is located in the southern San Joaquin Valley. This area is bound by the southern portion of the Sierra Nevada Mountain Range to the east, the Transverse Ranges and the Tehachapi Mountains to the south, and the southern portion of the coast ranges to the west. The general topography of the Bakersfield region consists of alluvial terraces, fans, benches. and floodplains sloping westward fonn the foothills of the Southern Sierra Nevada Mountains to the'main drainage axis of the San Joaquin Valley. The Kern River, a perennial stream draining an extensive watershed in the souther Sierras, flows in a general southwesterly direction through the center of the' metropolitan Bakersfield area. Temperatures in this region average 57° F in the 'winter and 90° F in the summer months. Annual average precipitation ranges betvveen 4 to 6 inches, with most rainfall occuning between the months of November and ApIi1. '. :- -i.'·- .":. :';J õ:';,¡ ......,' ..;- ~:, ¡~"'d ;:{.', .". "'.-;"' ;;./~. ~., ,,~-: .':.1 .. 6.2 Geologic Conditions The San Joaquin Valley is a large basin lying between the Sierra Nevada range to the east, and the coastal ranges to the west. This basin was fonned in intennittent westerly tilting of the underlying Mesozoic crystalline rocks, which elevated the Sierra Nevada and depressed the western portion of the block. DuIing Tertiary and Quaternary periods, both marine and non-marine sediments were deposited on the basement rocks as the western portion was depressed. The tertiary rocks consist of a series of stratified sediments including sandstone, conglomerates, and shales that are relatively thin along ~ t:~ft Recyc1c~r Recycled Paper 4 ~~DC'dT~li~ ® ~t-ßlWœleE{l ENVIRONMENTAL CONSULTANTS .
