(Twining) has prepared this letter to request closure for the former UST located at the above referenced address. A summary of the events occurring since our last correspondence is presented below for review by your department. Following the excavátion of approximately 1~0 cubic yards of soil containing gasoline constituents on September 5, 1990, soil samples were obtained by Twining from each sidewall and from the bottom of the excava~ion. The soil samples were analyzed by Zalco Laboratories for Volatile Aromátic Hydrocarbons (BTEX) and, Total Petroleum Hydrocarbons - Gasoline (TPH - Gas). The laboratory documentation for the September 5, 1990 sampling event is attached. The results of the soil sample analyses indicate that the cleanup levels established for the project as per our letter dated August 29, 1990 have been achieved. Following excavation the soil was transported ,by truck to 1127 Sumner Street and stockpiled in approximately 50 cubic yard segments at which time Twining obtained' composite soils samples from each stockpile. The soil samples were analyzed by Zalco Laboratories for TPH Gas. The laboratory documentation is attached. Based on the results of the laboratory analyses and the recommendations of your department, approximately 100 cubic yards of the stockpiled soil was spread on the site and allowed to aerate uncontrolled. The soil was disced two to three times per week. Composite samples were obtained by Twining and analyzed for'TPH -Gas on November 7, 1991. The laboratory results revealed non- detectable concentrations of TPH. At that time your department advised Twining that the remaining 50 cubic yards of soil be allowed to aerate uncontrolled. Aeration operations continued on the site -··-·--··-·anda composite sample was obtained by Twining on January·-10,'-1991.- "-. o 2527 Fresno Street· P.O. Box 1472 Fresno. California 93716 .

Based on our field observations at the time of excavation' and the laboratory results obtained, Twining believes that this site has been succesfully remediated and is no longer a threat to the environment or to the public health and safety. Twining requests tha't your department grant clean closure status to this site and consequently allow MRG to dispose of the remediated soil. Please be advised that. ,.because _ MRG is currently renting ,_the _ stockpile location property, that additional expensè may be deferred by receiving a prompt and positive response from your department. On behalf of MRG, Twining thanks you for your cooperation and patience during this project and we look forward to working with you on others.

As per our discussion on August 21,1990, we have revised the clean-up levels for the above referenced site. At the request of your departmen~ Twining has reevaluated the minimum concentrations of BTEX and TPH that may be left in place based on the potential for perched groundwater conditions occurring at depths of 40 feet to 80 feet below site grade. Using the "Leaching Potential Analysis ,for Gasoline" method as described in the LUFT Field Manual based on the following parameters: 1. Minimum depth to groundwater - 25 to 50 ~eet. 2. No subsurface fractures. 3. Average annual precipitation - <10 inches. 4. No man-made conduits which could increase vertical migration. 5. No unique site features. resul ts in a total score of 45 points for the site. This score allows BTXE!TPH concentrations of .3, .3, 1.0, 1.0, and 100 parts per million respectively to be left in place. These clean-up levels will be met for the referenced site. Please be advised that the contractor anticipates beginning excavation on Wednesday, September 8,1990. I will notify your office of any· deviation from the proposed work schedule. _h_ ..u._..·..n___._.. o 2527 Fresno Street . P.O. Box 1472 Fresno, California 93716 .

As per our discussion on August 21, 1990, we have revised th~ clean-up levels for the above referenced site. At the request of your department Twining has reevaluated the minimum concentrations 'of BTEX and TPH that may be left in place based on the potential for perched groundwater conditioris occurring at depths of 40 feet to 80 feet below site grade. Using the "Leaching Potential Analysis for Gasoline" method as described in the LUFT Field Manual based on the following parameters: 1. Minimum depth to groundwater - 25 to 50 {eet. 2. No subsurface fractures. 3. Average annual precipitation - <10 inches. 4. No man-made conduits which could increase vertical migration. 5. No unique site features. results in a total score of 45 points for the site~ This score allows BTXE/TPH concentrations of .3, .3, 1.0, 1.0, and 100 parts per million respectively to be left in place.

INTRODUCTION ,. "" "'"-=-" ''''-'''1-. 0 This report presents a revised remedial action plan (RAP) for the mitigation of soils containing gasoline constituents resulting from a former 500 gallon underground gasoline tank which was maintained by MRG Investment Group (MRG), at 215 Sumner Street in Bakersfield, California until September 2, 1988. The preparation of this RAP was authorized by Mr. Maurice Glascock on February 16, 1990, and in accordance with our proposal dated February 12, 1990. The revision of the plan was requested by Mr. Joe Canas of the Kern County Department of Environmental Health (KCDEH) 'on July 10, 1990. This report summarizes the existing site features, the region's geological and hydrological characteristics, and the project history. In addition, the proposed remedial action alternatives and the remedial action design criteria are discussed. Finally, the preferred remedial action method for the site is outlined. The report appendix contains the logs of the soil borings (Appendix A). This -RAP report was prepared by the Environmental Engineering Division of The Twining Laboratories, Inc. (Twining) in Bakersfield, California. __"" _':0.__ -.;-_.,....'-_~...._<. ""'~-"'"'_,'._~~___....'"=.".~~+__,...~'_r-~".._. __.m . ...,......~__.__..~ >~_~_...~.. ""'_, - .

The site is bound on the north by Sumner Street, on the south by East 21st Street, on the east by residential and commercial development, and on the west by commercial development and Sonora Street. A site location map is presented on Drawing No.1. The site is occupied by warehouse buildings and storage areas which are presently being used by an air conditioning and heating supply company (BASCO). The approximately 40 year old, 500 gallon underground gasoline storage tank was in the alley that divides the site, adj acent to the southeast corner of the warehouse structure fronted by Sumner Street. A site plan depicting these features and the former tank location is presented on Drawing No.2. 2.2 Reqional Geoloqy: Bakersfield is located within the southern San Joaquin Valley Region of the Great Valley (valley) Geomorphic Province of California. Surficial deposits in the Bakersfield area occur as Quaternary alluvium derived from the Sierra Nevada which comprises the eastern border of the valley. _~"..~ .....,..-..........__,_.=....""""_.. ,......=---"_...,...,,~~_. ,. -'" _ "'=--.-.-,..=......____=_"'""'-<r -".''"-"''.'' _'"-~""".-=-.,..

B-1 that soils with elevated concentrations of TPH extend vertically to a' depth of between 11. 5 and 16.5 feet BSG. Because the invert elevation of the former tank was located approximately 8 feet BSG and because petrol~um hydrocarbons in soils do not usually migrate upward under normal conditions, it may be assumed that the upper 6 to 8 feet of soil has not been affected by the product leakage from the former tank and that these soils may not require remediation. However, because the possibility exists that during the temporary backfilling operation, after the tank was removed, that contaminated soils may have been commingled with uncontaminated soils, the potential exists for the upper 6 to 8 feet of soils to also contain elevated concentrations of hydrocarbons. The estimated extent of the soils containing elevated concentrations of petroleum product are illustrated on Drawings No.3 and No.4. .

From the evaluation, it was determined that the site soils exceeded the maximum allowable levels for B, T, X, E and TPH (1, 50, 50, 50 and 1,000 ppm, respectively) for the site specific conditions outlined. On March 1, 1990, a meeting was held between Mr. Joe Canas of the KCDEH, Mr. Maurice Glascock of MRG, and Mr. Bruce Blythe of , Twining. During the meeting the results of the RI Investigation were discussed and it was determined that, the site would require remediation. This decision was based upon the results of the laboratory analyses of the soils samples from soil boring B-1 and also upon Mr. Canas's concern that the existing underground utility piping in the vicinity of the contaminated area could act as pathways by which potentially explosive petroleum vapors could be conducted into the adjacent warehouse building.

The soils requiring remediation exist below the City of Bakersfield right-of-way which is defined as a distance of 10 feet outwardly from the centerline of the alley. A portion of the contamination is believed to have migrated beneath the southwest corner of the warehouse structure located on the north side of the alley. Underground utilities in the form of a 6-inch diameter city sewer line and a California Water Service Company distribution line are located approximate to the centerline of the alley. The project site is located within the primary traffic area for the employees and customers of an air conditioning supply company whose peak business months occur during the spring and summer months (May through September). . ~ '-. .-. - - -~. _<.r_,"~ ....___..~-~ -""."~..,,,-<"-,--.--.--..--.,~ .-, .,,-,-,-,-,.~ .,..-...--.-.,,,....

In the event that the upper 6 to 8 feet of soil is found to be, contaminated by previous commingling of soils than the volume of soils requiring remediation may be increased by as much as 100 cubic yards. 3.3 Potential Environmental Effects: The soils containing elevated concentrations of TPH are separated from groundwater by approximately 190 feet. The average annual rainfall in the Bakersfield area is approximately 6-inches. The ground surface in the vicinity of the former tank location is paved with asphaltic or portland cement concrete. Our remedial investigation identified a relatively impermeable clay layer in the subsurface soils at a depth of approximately 30 feet BSG which could act as natural barrier to migration. Thus, it is unlikely that the petroleum product contained in the soil could leach to groundwater.

This condition could result in an environmental threat if the vapor exposures are significant to workers, or the concentrations were to reach explosive levels and an ignition source were present. It should also be noted that the existing contaminated soils represent a potential liability to the future marketability, the market value, ~nd uses for the proper4y. In consideration of the above potential environmental effects, MRG has chosen to remediate the soils containing concentrations of TPH greater than 1,000 ppm. 4.0 REMEDIAL ACTION ALTERNATIVES An evaluation of remedial action alternatives was made to select an appropriate remedial method based on the site· specific conditions. Information summarizing the possible remedial action ) alternatives is presented in the following subsections.

In addition" the No Action alternative would not achieve a clean closure, thus, th~ future marketability and us~s for the property could be impacted if this action were selected. Based on the above considerations the No Action alternative is not considered feasible' for this site. 4.2 Excavation and Removal: The Excavation and Removal remedial action alternative would involve physically removing the volume of soils containing concentrations of TPH greater than 1,000 ppm, transporting the soil to, and disposing of the soil at a Class II (designated waste) disposal facility. Soil excavations of up to 20 feet can usually be accomplished with a backhoe. Removal of larger volumes of soil at greater depths is usually accomplished by using larger earthmoving equipment.

It is estimated that a volume of approximately 500 cubic yards of soil would have to be excavated to accomplish the remediation,' of this amount 130 to 190 cubic yards could require disposal. Thus, approximately 300 to 350 cubic yards of soil would need to be stockpiled on-site for reuse as backfill. In addition, approximately 130 to 190 cubic yards of imported soil would be required to replace the soil disposed of. The backfilled area of approximately 850 square feet would require repaving with asphaltic concrete paving. The Excavation and Disposal alternative would result in the closure of the alley (a City of Bakersfield right of way) to through traffic and would also impact the working operations of the business located at the site if the work was performed on a weekday. It is estimated that one to two working days would be required to complete the work. ...--.-' -----.---- .-~ '"' ....,...-. _...~ ".'---,. dlœd~~·cJfl£· Fresno Modesto Bakersfield Visalta r ' " ¡ , I :\ . , ¡. r: ¡ · i j , ! \ ./- I, -( TL 989-013-06 Page 14 -- , Soils containing non-hazardous levels of petroleum hydrocarbons requirepdispos~~_ ë;lt ,_~. state certifi~d class~_~~:J:_~~~~~~~~lõ~:::~~~~~~::-_~o.s~______ for disposal is approximately $200.00 per cubic yard of soil.

The aeration method operates on the they will volatilize when exposed to standard temperature and pressure conditions. The excavation and aeration method has the /" \ i capability to significantly reduce the concentrations of B, T, X, E and TPH in the soil to levels below regulatory acceptance levels. The excavation and aeration method is considered cost effective in most cases because transportátion and disposal costs are virtually eliminated from the total remediation costs. Because hydrocarbon vapors are generated by this process, this remedial alternative usually requires the permission of the Kern County Air Pollution Control District. Advantages of excavation and aeration include ex-situ remediation, a relatively simple workplan, low maintenance, low cost, the rapid reduction of VQC concentrations to meet acceptable levels, and a minimal impact on facility operations. Disadvantages of this type of method are the size of the excavation required to mitigate large volumes of soil, space requirements necessary to perform the process, possible environmental concerns' to populated -~ - ~.._-_.- . .. - - - -.-,", .n._._ _. __ _ dlud~~.dm.

Prior to placing and spreading the soil; the area proposed for use should be covered with a triple layer of impermeable material to prevent ver~ical migration of hydrocarbons into the on-site soils. This may be accomplished by using heavy gauge polyethylene material or asphaltic concrete paving. If a 'paved area is available for use, then polyethylene sheeting may not be required. It will also be \. necessary for the proposed site to be fenced with a locking gate to prevent unauthorized individuals from entering the remediation zone.

Dear Mr. Blythe: This Department has completed the review of the site remediation workplan for the Basco facility located at 215 Sumner Street in Bakersfield, California. Our review has determined that insufficient information has been provided to perform a complete evaluation of the proposed mitigation activities. The proposed remediation action must be performed in accordance with the following requirements. 1. The amount of soil to be aerated will be based on the TPH concentration levels, in each 50 cubic yards of excavated contaminated soil. 2. The TPH concentration levels must be based on one composite sample retrieved from four separate locations in each 50 cubic yards of excavated soil and composited at the lab. The following sections must also be addressed adequately or revised prior to receiving approval of the workp1an: ' 1. Based on information received from nearby assessments, groundwater has been identified in the range of 40 to 70 feet in depth. The clean-up levels must now be reevaluated based on the above information. 2. The amount of soil to be treated must include the top 6to 8 feet of the former tank fill since it is unknown whether the contaminated soil and the surrounding clean fill were commingled. 3. From where will the confirmation soil sample be retrieved? 4. A site safety plan must be included as part of the workplan. '~---5~~ -" Has an OSHA excavation' permit been obtained? 2700 "M" STREET, SUITE 300 BAKERSFIELD, CALIFORNIA 93301 RECYCLED PAPER (H().'j) 8ó13636 FAX: (gO,,)) gó13429 - Bruce Blythe .

When a site has been selected we will contact you and provide you with sufficient information regarding the proposed site to ensure that it meets with your department's approval. It is anticipated that the remedial action will be conducted sometime this summer or the early autumn of this year.

The regional direction of groundwater flow is northeast. No known perched water table èxists at the site location. Depth to groundwater and shallow groundwater flow can be affected by groundwater production well pumping, seasonal recharge conditions, and other variables in the vicinity of the site. 2~4 Proiect.

It was 'also ".::"". ,. ¡ determined, based on the laboratory analyses of the soils samples taken at depths of 11.5 feet and 16.5 BSG in soil boring B-1 that soils with elevated concentrations of TPH extend vertically to a depth of between 11.5 and 16.5 feet BSG. However, because the invert elevation of the former 'tank was located approximately 8 feet BSG and because petroleum hydrocarbons in soils do not usually . ~ migrate upward under normal conditions, it is assumed that the upper .¡t' ! j - ~ (.v.\.,· 6 to 8 feet of soil has not been affected by the product leakagev CD'" from the former tank and that these soils may not require remediation. The estimated extent of the soils containing elevated concentrations of petroleum product are illustrated on Drawings No. 3 and No . 4 . The RI report also concluded that the soils containing elevated concentrations of TPH are separated from groundwater by an interval of approximately 190 feet and that the groundwater beneath the site had probably not been impacted by the petroleum product migration. ~-. -..,..,,-~. -'" -"'-~--, -=--=,,....---,------- """,..- - _:~. __,""""".."..,.,r.~.". -'-.-."" -~.~-"""""'~-----,",--'''--'' jv& ~1jb 7<1" ~~ . ,\iO -. . -. . - .--" - . .

During the meeting the results of the RI Investigation were discussed and it was determined that the site would require remediation. This decision was based upon the results of the laboratory analyses of the soils samples from soil boring B-1 and also upon Mr. Canas's concern that the existing underground utility piping in the vicini ty of the contaminated area could act as pathways by which potentially explosive petroleum vapors couid be conducted into the adjacent warehouse building.L:?uring the meeting Mr. Canas also stated that any contaminated soils which may exist beneath the warehouse structure could be left in place and would not require remediation J .. 0--':" ~ ""~ ",of """"\ w-Å~>r. .....J ¡1~./-j, <>..ö ¡----r ./..K..o- ~aH~ ~ð-"- . --- - ".... .-'-~-'~~' h.. ......__ -__ ,-, dlud~~·dru;· Fresno Modesto Visalia Bakersfield I fd . ¡., ¡ !

The soils containing ." , elevated concentrations of TPH are separated from groundwater ,by , . .. approximately 190 feet. The average annual rainfall in the Bakersfield area is approximately 6-inches. The ground surface in the vicinity of the former tank location is paved with asphaltic or portland cement concrete. Our remedial investigation identified a relatively impermeable clay layer in the subsurface soils at a depth of approximately 30 feet BSG which could act as natural barrier to migration. Thus, it is unlikely that the petroleum product contained in the soil could leach to groundwater. Subsurface domestic water and sanitary sewer piping exist in the vicinity of the contaminated soils. These subsurface features could theoretically act as pathways by which petroleum vapors could migrate into the warehouse building located adjacent to contaminated area. ,This condition could result in an environmental threat if the vapor exposures are significant to workers or the concentrations were to reach explosive levels and an ignition source were ,present.

The No Action alternative would be the least costly method of those evaluated, however, the concentrations of B, T, X, E and TPH at the site exceed the maximum levels established by LUFT (May 1989) for the site specific conditions and also man-made condui ts which could act as pathways for migration of petroleum' vapors exist in the vicinity of the contaminated area.

Soil excavations of up to 20 feet can usually be accomplished with a backhoe. Removal of larger volumes of soil at greater depths is usually accomplished by using larger earthmoving equipment. Because the extent of contamination at the site appears to be limited to a depth of approximately 16.5 feet BSG, the excavation and transportation could probably be accomplished by using a backhoe and dumptrucks. The excavation would require a slope of between 3/4:1 and 1:1 horizontal to vertical slope. The lateral dimension of the area requiring excavation is estimated to be circular in shape approximately 20 feet in diameter. The overall dimension of the excavation, taking into account the required slope could approach 40 / feet in diameter (excluding the area beneath the building). It is estimated that a vol~e of approximately 500 cubic yards i of soil would have to be excavated to accomplish the remediation, of this amount 130 to 190 cubic yards could require disposal.

The Excavation and Disposal alternative would result in' the .,.. . ;' . closure of the alley (a City of Bakersfield right ofnway) to through traffic and would also impact the working operations of the busines~ located at the site if the work ,was performed on a weekday. It is estimated that one to two working days would be required to complete the work. . Soils containing non-hazardous levels of petroleum hydrocarbons require disposal at a state certified Class II landfill. The cost for disposal is approximately $200.00 per cu~ic yard of soil. Since transportation costs associated wi th soil disposal are based on I driver hours, the GSX landfill located near Buttonwillow, California would appear to be the most cost effective disposal location for this project. Prior to disposal the soils would require laboratory analysis for B, T, X, E and TPH to ensure waste acceptance criteria.

Estimated Total: $ 47,157.48 4.3 Excavation and Aeration Treatment: The excavation and aeration remedial action alternative is a method of ex-situ treatment which involves the mitigation of volatile organic compounds (VOC) from soil by allowing the VOC to volatilize under atmospheric conditions. The aeration method operates on the principle that VOC have relatively high vapor pressures and that they will volatilize when exposed to standard temperature and pressure conditions. The excavation and aeration method has the capability to significantly reduce the concentrations of B, T, X, E and TPH in the soil to levels below regulatory acceptance levels. I- i The excavation and aeration method is considered cost effective in most cases because transportation and disposal costs are virtually ! ¡ dlud~~·d~· Fresno Modestó Visalia Bakersfield e( e( TL 989-oi3-0S Page 15 r i ! eliminated from the total remediation costS. .

Disadvantages of this type of method are the size of the excavation required to , i , , mitigate large volumes of soil, space requirements necessary to perform the process, possible environmental concerns to populated areas, and the costs associated with the laboratory testing requi~ed to determine if the desired clean up levels have been achieved. . Based primarily on the small amount of soil to be remediated and the predicted low costs involved. to remediate the soils by this technique, the excavation and aeration remedial action alternative is cons idered feasible for this project.

A draft Remedial Action Plan has been prepared by Twining and subsequently reviewed by the R.P., Mr. Maurice Glascock. After reviewing our report and receiving several cost estimates for the excavation and disposal of the gasoline contaminated soils, Mr. Glascock has decided to attempt to remediate the site by excavating and aerating the contaminated soils on-site. He is now in the process of negotiating a real estate transaction by which he can Q obtain property to accomplish this method of mitigation.. If Mr. Glascock is successful in acquiring the property, a revised Remedial Action Plan will be prepared and submitted to the Department of Environmental Health Services and to the Air Pollution Control District for consideration.

The valley is a geosyncline that has been " ' filled with a sequence of marine and continental sedimentary rocks - .0_-. of Tertiary and Quaternary age resting uncomformably on a basement complex of metamorphic and igneous rocks (Dibblee and Oakshot, 1953). The surficial Quaternary deposits in the Bakersfield area occur as alluvial deposits derived from the Sierra Nevada Range to the east. These deposits generally are oxidized, and on the upper parts of the larger fans adjacent to the mountains, consist of moderately to highly permeable, yellowish brown gravels, sands and silts. On the lower parts of the fans, these deposits consist of poorly to moderately permeable, yellowish brown sands and silts. The surficial geology of the subject property consists of alluvial sands and silts (Wood and Dale, 1964). Groundwater in the site area occurs within the Edison subarea of the Edison-Maricopa area. This subarea, includes the urban and irrigated areas along the southeastern border of the San Joaquin Valley between the Kern River and Caliente Creek.

This work was conducted in accordance with our RI Work Plan dated March 6, 1989.( In addition, the data obtained were . evaluated to assess the potential environmental effects of the petroleum product migration. Finally, the need for additional studies and/or remed~al actions were assessed. A summary of the actions taken, during this investigation is outlined as follows: 1. An RI Work Plan (dated March 6, 1989) was submitted to the KCEHD and subsequently approved verbally ~y the KCEHD. 2. Mr. M. R.

The soil samples were analyzed for B, T, X, E and TPH (Gasoline). ,During our field investigation it was not possible to locate a slant drilled soil boring beneath the existing ,warehouse building located to the north of the former tank location due to limited drill rig access caused by the building located directly south of the tank locatiori. It was also not possible to locate a soil boring to the east of the former tank location due to co~flict with existing overhead communication and power lines. The KCEHD was informed of this deviation from our RI Work Plan by a telephone conversation between Mr. Bruce Blythe (Field Geologist) and Ms. Amy Green (KCEHD) on October 11, 1989.

Based on the analytical results of the soil samples retrieved from the soil borings, the known horizontal extent of soils with detectable concentrations of key petroleum product constituents appears to be limited to a distance of approximately 10 feet from the center of the former tank location. However, because it was not possible to advance soil borings to the north or to the east of the former tank location it was not possible to determine the extent of any migration that may have occurred, in these directions. Given the granular nature of the on-site soils, it would be reasonable to assume that the petroleum product migration has o,ccu r red pr imar ily in a vertical direction symmetr ical around the vertical axis of the former tank location. The above data suggests that petroleum product may have migrated horizontally beneath the warehouse building located to the north of the former tank location.

Depth to groundwater beneath the site is approximately 200 feet BSG. In addition, the average annual rainfall in the Bakersfield area is approximately 6 inches. Since the site is located on alluvial fans, no known subsurface fractures exist. In addition, no manmade conduits which could increase the potential for vertical migration of petroleum products were identified during the investigation. Finally, the only unique site featurè which could promote migration of petroleum constituents is the coarse nature of the subsurface soils. However, this condition is abated somewhat by the underlying clay layer which separates the affected soils from underlying groundwater. The petroleum product appears to be comprised of gasoline fuel as demonstrated by the analytical results of the soil sample analyses and the product hist6ry of the tank.

A clean closure would insure that the future marketability and use for the property would not be impacted by the existing site conditions caused by the former underground st9rage tank. Soils containing elevated concentrations of B, T, X, E and TPH detected in the soil sample retrieved from soil boring B-1 at a depth of 11.5 BSG, are separated from groundwater by approximately 190 feet, thus, it is unlikely that groundwater has been impacted by the petroleum product migration from the former tank. 6.3 Addítional Studies and Remedial Actions: Three remedial action alternatives for the area beneath the underground fuel tank were evaluated on a preliminary basis: 1) No action, 2) soil removal and disposal at a State certified landfill, and 3) soil removal and treatment by aeration.

The excavation and treatment by aeration remedial action alternative would involve removing the soils containing key petroleum product constituents and spreading the soils in a thin layer on-site to allow aeration., In addition, the excavation of the affected soils will encroach the adjacent structure~ This method may require shoring the building or possibly leaving in-place these soils containing petroleum product constituents which are located beneath the structure (if this condition exists). Also, it may be necessary to conduct additional testing to determine if petroleum product has migrated. This alternative may require the approval of the KCAPCD.

The site is bound on the east and west by existing commercial buildings, on the north by Sumner Street, and on the south by an alley. The si te is 'occupi ed by an' existin'g warehouse building' presently being used as an air conditioning and heating supply company. At the time of our field visitation, the tank and dispenser had been removed and the excavation had been backfilled. The tank under investigation was a 500 gallon single walled steel tank and was located at the southwest corner of the site. A Site Map showing the tank location is presented on Drawing No.2. It is understood that the tank invert was at an elevation approximately 6 feet below existing grade. f'Vl, ¡(>, IN.,' Ç~/'''' ,:-,1./ r According to Mr. Morris Glascock, of M.R.G. Manage~ Group, the underground tank is thought to have been installed approximately 35 to 40 years ago at the time the existing warehouse building was constructed, and that the tank was used for the storage of regular leaded and unleaded gasoline. However, the tank r, dlœd~~,d~· Fresno Modesto Visalia Bakersfield r i I 1- r- r -. J..., I ! I, e- .'

In general, the analytical results revealed high - concentrations of gasoline constituents (Appendix A) at 6 feet beneath the tank. 2.3 Problem Statement: The area of concern regarding the project site is the extent of gasoline contaminated soil in the area' of the underground storage tank. In a letter dated February 7, 1988, from Ms~ May Weddell of the Kern County Health Department, . Environmental Health Division, Ms. Weddell indicates that her department requests a site characterization study to determine the extent of this contamination. 3.0 OBJECTIVES OF INVESTIGATION: The objectives of the proposed engineering investigation are presented below: 1.

Glascock of M.R.G. Managc@ent Group regarding the location of the tank, the previous investigation performed, and the history of the underground tank. All field work associated with the collection of soil samples from the project site would be supervised by an engineer from our firm. The exploratory soil boreholes will be drilled at the proposed locations using a truck mounted drilling rig equipped with hollow stem continuous flight augers. The hollow stem augers will be used to ensure sample integrity by preventing soils from caving to the bottom of the borehole during drilling. Prior to drilling each borehole, the hollow stem augers will be steam cleaned to prevent cross-contamination between boreholes. dlud~~·dru;· Fresno Modesto Visalia Bakersfield I I e TL 989-013-00" \,-~" /;,',\ \, ~ "- ~\~ ,J-' u'/ 0;/ .

The retrieved sample will then be field tested using a total 60 hydrocarbon drager tube with a detection limit of 100 parts pero1v'" million. In addition, a portion of each soil sample will be retained for shipment to the laboratory.

This letter is an official notice to inform you that the property described above has been determined by Kern County Environmental Health to be the site of an unauthorized release of hazardous materials from an underground storage tank. This notice is sent to you because our records indicate that you are a responsible party for this property. As a responsible party, you must provide for all studies and work relating to the above described property and the cost for oversight of these activities. California Health and Safety Code Chapter 6.7 and Kern County Ordinance Code Chapter 8.48 require a determination of the threat to the environment as a result of this release. THE RESPONSIBLE PARTY SHALL, ON A TIMELY BASIS, DEVELOP A SITE CHARACTERIZATION, FEAS IB ILITY STUDY AND REMEDIAL ACTION PLAN FOR KERN COUNTY ENVIRONMENTAL HEALTH'S REVIEW AND APPROVAL BEFORE THE WORK IS INITIATED. Enclosed you will find attachment "A", Handbook UT-35, which states the minimum required site workplan activities, the necessary requirements for selecting environmental contractors qualified to perform this work, a glossary of terms, example illustrations, and a section discussing the answers to commonly asked questions. The cost incurred by Kern County Environmental Health for the oversight of the work for the site characterization, feasibility study, remediation action plan, site remediation, and ongoing monitoring is not covered by any fees or permits. These costs are recovered by Kern County Environmental Health i~ one of the two ways described bèlow. It is your responsibility to select t~e method, of oversight cost recovery under the terms of the (A) State contract or (B)' County of Kern Local Agreement Option. These options ONLY pertain to costs associated with oversight. (A) STATE CONTRACT The State Leaking Underground Storage Tank Pilot Program provides a mechanism for the State to reimburse the County for County oversight. The County will conduct the necessary oversight and bill the State Water Resources Control Board under this State ~ontract. The State will then charge you, a responsible party, for both the costs OISTRICT QFFI(':FC; · e incurred by the County, and the State pertaining to your site. (B) COUNTY LOCAL AGREEMENT Kern County Environmental Health is providing this option for those who prefer to pay the County directly an~ avoid the addition of State costs: Prior to the County's performance of services, this option requires your deposit of $1,000.00 (one thou~and dollars) with the County to be held in the Local Option Trust Account. Charges for County oversight are made against this account. In this option, a responsible party must_enter into a County agreement, attachment "B". To safeguard the environment, the environmental sensitivity (Attachment "C") of this site has been reviewed by Environmental Health to determine the potential threat for "groundwater contamination. Only sites determined to -be non-environmentally sensitive may enroll in the Local Option Agreement. The site described above is not in an environmentally sensitive area and may be enrolled in the LO,cal Option Agreement; however, the County of Kern reserves the right to cancel any Local Option Agreement, should it be discovered that groundwater contamination or a unique, complex hydrogeological condition exists., In such cases, Environmental Health will utilize the State contract to pay for County oversight activities. The County of Kern reserves this right for any site even when the site is located in a non-enviro~mentally sensitive area. It is necessary for you to respond in writing within ten (10) calendar days of receipt of this letter to advise Kern County Environmental Health of your choice: either the State Contract or the County's Local Agreement option. If you select the County's Local Agreement, please sign the Local Agreement, enclosure "B", and return it with your check for $1,000.00 (one thousand dollars) made payable to the County of Kern, addressed to Kern County Environmental Health 2700 M Street, Suïte 300, Bakersfield, CA 93301, Attention: Underground Storage Tank Contract Administrator. If you select the State Contract, please indicate that you have made this selection and that you have read attachment "D", the official notification, in a letter sent to the address indicated above. Failure to respond in writing to this notice within ten (10) calendar days will automatically result in over~ight cost recovery for your site(s) to be placed under the ter~s of the State Pilot Program for Leaking Underground Storage Tanks. Enclosure "D" will then serve as the official notification of your enrollment into the State Pilot Program for Underground Storage Tanks. If you should have any questions regarding this matter, please contact' John Nilon, contract manager, at (805) 861-3636.
