Former HõlâenTruck-Elaza,3-1-1-5-Buek-Qwens-Blv..cLJ Apex Bulk Commodities, 2111 Bricyn Ln Dear Mr. Noonan, On behalf of this Department and the City of Bakersfield, we thank you for your diligence and assistance in overseeing the remedial activities to completion at the above referenced Underground Storage Tank (UST) release sites. From the time of our referral to your Board (that groundwater was determined to be impacted) to your case closure, was less than four years at each site. Your expedience is particularly noteworthy because there are two other groundwater investigation sites in the City where Kern County, as the holdover Local Oversight Program (LOP) agency, is now well into their 17th year of oversight on those two other sites. The contrast in clean-up response times is noteworthy and you and your staff should be commended. We appreciate the close working relationship between our agencies and look forward to the completion of other successful projects in the future, !, .. -----"- -----, -..........--- ._~---~- -........--,-,-'-"------~._-,--~._--- ..-.. cc: J.

Thank you for your cooperation through out this investigation. Your willingness and promptness in responding to our inquiries concerning the former underground storage tanks are greatly appreciated, Based on the information in the above-referenced file and with the provision that the information provided to this agency was accurate and representative of site conditions, this agency finds that the site investigation and corrective action carried out at your underground storage tank site is in compliance with the requirements of subdivisions (a) and (b) of Section 25296.10 of the Health and Safety Code and with corrective action regulations adopted pursuant to Section 25299.3 of the Health and Safety Code and that no further action related to the petroleum release at the site is required. A summary ofthe information in the above-referenced file is included in the Case Closure Summary, a copy of which is enclosed. This notice is issued pursuant to subdivision (h) of Section 25296.10 of the Health and Safety Code. Please contact Mr, John M. Noonan at our office if you have any questions regarding this matter.

DATE: 13 October 2004 SUBJECT: CASE CLOSURE SUMMARY, UNDERGROUND STORAGE TANK RELEASE, FORMER HOLDEN TRUCK PLAZA, 3775 BUCK OWENS BOULEVARD, BAKERSFIELD, KERN COUNTY Background Information The site was developed as a truck stop in the late 1940s. The site is approximately 3,000 feet west of the Kern River approximately 2,700 feet southwest of a Kern County Water Authority recharge pond, and approximately 1,200 feet southwest ofthe Calloway Canal. Two 10,000-gallon gasoline USTs, two 12,000-gallon diesel USTs, and associated dispensers and piping were installed in the area of a former UST cluster during 1985 and were taken out of service prior to 1998, The Bakersfield Fire Department (BFD) learned of the existence of unpermitted nonoperating USTs at the site and required UST system upgrades or removals in a letter dated 12 October 1998. The USTs were removed on 30 October 2000. One 3,000-gallon waste oil UST was removed on 4 December 2000. The presence of a 12,000-gallon diesel UST in the southern portion of the site was mentioned in site records but was-not discovered by-hando augering; 'Fotal-petroleum hydrocarbons-as diesel (-'fPH:.d) was detected in samples collected beneath the middle and west ends of the south diesel tank, the west and east ends and middle of the north diesel UST, the three diesel dispensers, and the waste oil UST during the 2000 UST removals, TPH as heavy oil was also detected in the sample collected from the waste oil UST, In a letter dated 24 January 2001, the BFD required further assessment to determine the lateral and' vertical extent of impacted soils. The CBFD referred the case to the Regional Board by a letter dated 5 March 2001. In a letter dated 26 January 2001, the KCEHSD required the removal of the 12,000-gallon diesel UST reportedly still on-site. The UST was located in the southern portion of the site and was removed on 18 July 2001. A significant fuel release was not discovered during subsequent assessment beneath this former UST, California Environmental Protection Agency a Recycled Paper Former Holden Truck Plaza Closure Summary - 2- 13 October 2004 ¡' Site assessment conducted during June and December 2001 identified and determined the extent of three soil plumes impacted by diesel fuel. The largest plume, in the northern portion of the site at the former UST cluster, was elongated toward the west by downgradient transport of hydrocarbons on the water table. This plume extended vertically to approximately 39 feet bgs and had an estimated volume of 2,000 cubic yards. TPH-d concentrations up to 22,000 mglkg were detected within this plume. The second and third plumes were beneath former and present fuel dispenser islands, respectively, The second plume extended to 20 feet bgs, had an estimated volume of 400 cubic yards, and a maximum detected TPH-d concentration of 8,000 mglkg. The third plume extended to 13 feet bgs, had an estimated volume of 50 cubic yards and a maximum detected TPH-d concentration of 28,000 mglkg. The soil plumes were excavated during August and September 2003. Approximately 12,000 cubic yards of soil were initially removed and stockpiled on-site, Approximately 4,800 cubic yards of the soil was determined to be contaminated and was transported off-site for disposal. The remaining soil and clean fill material from off-site were used to backfill the excavations. Compaction testing was performed during backfill placement. TPH-d was not detected or was detected at low concentrations in confirmation samples collected from the excavation, confirming that most of the impacted soil had been removed. Four groundwater monitoring wells have been installed on-site. Seven quarterly groundwater monitoring events were conducted prior to soil excavation, TPH-d concentrations detected in groundwater in a monitoring well within the largest area of impacted soil ranged from 640 to 5,400 micrograms per liter µg/L. TPH-d concentrations in a monitoring well downgradient of this soil ranged from 340 to 4,400 µg/L. Two semiannual monitoring events were conducted after soil remediation, TPH-d concentriltions in groundwater detected in the well within impacted area ranged from 400 to 480 µg/L, TPH-d concentrations detected in the downgradient well ranged from 990 to 1,400 µg/L. Gasoline constituents and polynuclear aromatic compounds (P AHs) were occasionally detected at vèry low concentrations during the monitoring history. The site is within an area of commercial properties along the east side of the State Highway 99 right-of- way, Domestic water is supplied by City of Bakersfield municipal water system, Active water supply wells were not identified within 1,000 feet of the site, Conçlusions I conclude that the total mass of residual hydrocarbons remaining in subsurface soils is small. Low concentrations of diesel range petroleum constituents remain in shallow groundwater in the vicinity of the former UST. Since the source of the release and impacted soils have been removed, and residual hydrocarbon concentrations remaining in soil and groundwater and are unlikely to pose a significant risk to potential . . environmental receptors, I recommend that a standard underground tan1c site closure letter be mailed to the responsible parties. I also recommend that the groundwater monitoring wells remaining on-site be properly destroyed if they are not to be maintained and that any remaining drums containing drill cuttings or purged groundwater be removed from the site for disposal.
