Based on the report and our subsequent telephone conversation, I do concur with Krazan's findings and recommendations. This soil can be used as a sub base underlying the asphalt concrete paving.

SITE DEVELOPMENT ENGINEERS October 1, 2001 Project No. 026-01347 , Mr. Howard Wines City of Bakersfield Fire Department Office of Environmental Services 1715 Chester Avenue Bakersfield, California 93301 RE: Soil Reuse American Real Estate Holdings Shopping Center Development Stockdale Highway and Village Lane Bakersfield, California Dear Mr. Wines: This letter, prepared by Krazan & Associates, Inc. (Krazan) at the request of Porter-Robinson Engineering Surveying (Porter-Robinson), seeks the City of Bakersfield Fire Department's (BFD) approval of a soil reuse which was conducted at the referenced site. Background On or about September 1, 2001, Krazan's technicians detected oil-stained soils in the area of the northeastern portion of a proposed building slab. These oil-stained soils were subsequently excavated to a depth of 18 to 22 feet below ground surface. Approximately 2400' cubic yards of oil-stained soil were removed from the location of the proposed Border's Books building. The soil removal progressed until the soil in the bottom of the excavation was not oil-stained. No soil samples were collected from the excavation. The soil was transported approximately 112' from the excavation, spread to a thickness of 5' over an area of 194' x 153'. The location of the soil excavation and soil reuse area are shown on the attached figure. The soil was compacted to 90 percent maximum density and covered by 4' of clean soil. On September 20,2001, two soil samples were collected from the oil-stained soil from the soil reuse area. The soil samples were collected using a trowel and placed into brass sleeves. Following sample collection, the ends of the sample sleeves were covered by Teflon® film and sealed with tight fitting plastic caps secured by Teflon® tape. The sample sleeves were labeled and placed in a cooler chest, 215 West Dakota Avenue · Clovis California 93612 · (559) 348-2200 · FAX (559) 348-2201 With Ten Offices Serving the Western United States 2601347 letter " e 'e Project No. 026-01347 'Page No.2 which contained synthetic ice and were cooled to approximately 4 degrees Celsius (4°C). The samples were then transported under chain-of-custody protocol to a state-certified analytical laboratory for analysis. Analytical Results . The soil samples were submitted for analysis of benzene, toluene, ethylbenzene, xylenes (BTEX) by EP A Method 8020, gasoline range organics (GRO) by EPA Method 8015M, and total recoverable petroleum hydrocarbons (TRPH) by EPA Method 418.1. The analytical results are summarized in Table ll. Copies of the certified ~nalytical report and sample chain-of-custody records are attached. The soil sample designated as "Soil West" did not contain detectable BTEX or GRO and did contain elevated TRPH concentrations. Soil sample "Soil East" contained trace concentrations of ethylbenzene and xylenes, moderate GRO concentrations, and elevated TRPH concentrations. Requested Soil Reuse It is the intention of Porter-Robinson to reuse the oil-stained soil as subbase underlying asphalt concrete pavement. It is Krazan's opinion that the requested soil reuse does not pose an unacceptable threat to human health and the environment. The rationale for this opinion is presented below. The oil-stained soil does not contain significant concentrations of volatile constituents. Crude oil has very low solubility (1.5 x 10-6 milligrams per liter), very low vapor pressure (1.1 x 10-6 atmospheres), and a high molecular weight (2.8 x 102 grams per mole). These characteristics indicate that the crude oil within the reused soil will be essentially immobile in its current environment. The presence of the overlying asphalt concrete will further reduce any tendency for the crude oil to leach and migrate vertically. Groundwater is reported to be approximately 200 feet below ground surface. Given the lack of significant volatile constituents and the very limited mobility, it appears the crude oil does not pose a threat to underlying groundwater. Given the placement of the oil-stained soil at a depth of four feet underlying a paved parking lot, it is highly unlikely that soil ingestion or dermal contact will occur. Based on the foregoing, Krazan respectfully requests that the BFD issue a written statement approving of the subject soil reuse activity. KRAZAN & ASSOCIATES, INC. With Ten Offices Serving the Western United States 260\347 letter <'- e e Project No. 026-01347 Page No.3 Limitations The findings of this report were based upon the results of our field and laboratory investigations, coupled with the interpretation of subsurface conditions associated with the subject excavation. Therefore, the data are accurate only to the degree implied by review of the data obtained and by professional interpretation. The excavation and sample locations were located in the field by review of available maps and by pacing or tape measurements from existing landmarks. Therefore, the excavation and soil sample locations should be consi~ered accurate only to the degree implied by the methods used to locate them. Chemical testing was done by a laboratory approved by the State of California Certified Hazardous Waste Laboratory. The results of the chemical testing are accurate only to the degree of care of ensuring the testing accuracy and the representative nature of the soil samples obtained. The findings presented herewith are based on professional interpretation using state of the art methods and equipment and a degree of conservatism deemed proper as of this report date. It is not warranted that such data cannot be superseded by future geotechnical, environmental, or technical developments. Please contact Mr. Arthur Morrill at Krazan if you have any questions or comments. Respectfully submitted, KRAZAN & ASSOCIATES, INC. WL =fJ- ~ Arthur H.
