EXECUTIVE SUMMARY This Report summarizes recently completed efforts to remove an underground storage tank (UST) for the Perachino Trust, 3971 Jefferson Street, Carlsbad, CA 92008, PLAN CHECK # AT 362, EST# H21823. In January/February of this year, a >30,000 gallon underground, fuel oil tank was removed from this site. The tank was made of concrete and its dimensions were approximately 34' x 14' and 10' deep. Asbury Environmental services was hired to remove the existing product and triple rinse the tank before removal/recycle. A copy of a manifests indicate 9,000 gallons of liquid (70% water and 30% fuel oil) and 500 gallons of rinseate were transported to DeMenno Kerdoon, 2000 N. Alameda Street, Compton, CA, 90222. Soil samples were taken from the tank excavation, at the bottom as well as from three of the four sidewalls. The laboratory results, provided by Sierra Laboratories, indicate the absence of hydrocarbon contamination (TRPH by EPA 418.1 and Diesel by EPA 8015M). We are requesting a letter of Site Closure ... No Further Action Required, for this site. II. BACKGROUND The property is located at 3971 Jefferson Street in Carlsbad, CA (Figure One, Page 3). In January/February, 1997 a 30,000 gallon, concrete, underground, fuel oil tank (LIST) was removed. Soil samples taken from the excavation at the time of the tank removal indicated no hydrocarbon contamination at the bottom of the excavation. No groundwater was encountered. III. TANK REMOVAL/SOIL SAMPLING ACTIVITIES Current Site Conditions A scaled Plan view was prepared after visiting the site (Figure Two, Page 4). The site is located on Jefferson Street, just north of Chinquapin Avenue in Carlsbad. The site includes a private residence and several greenhouses. The surface area surrounding the tank was cleared of greenhouses/buildings prior to NuTECH's arrival. Excavation Activities On January 10 and 14, 1997, NuTECH contracted to have the tank emptied and triple rinsed by Asbury Environmental Services. They are a State licensed transporter, EPA #CAD028277036. The liquid was transported as non-hazardous and delivered for recycling to DeMenno-Kerdoon in Compton (EPA #CAT080013352). Approximately 9,000 gallons of liquid (70% water and 30% fuel oil) and 500 gallons of rinseate were transported (Appendix A). NuTECH constructed a ramp and proceeded to demolish and excavate the concrete tank (vault). When the last of the tank was removed (1-31-97), ten soil samples were removed from the excavation bottom and sidewalls to confirm the removal of the contamination to below action levels. A few days later (2-4-97), nine more bottom samples were obtained under the guidance of the San Diego Hazardous Materials Department (HMMD). Figure Three, Page 5 is a plan view of the excavation with the soil sampling locations displayed. The soil sampling containers were sealed, packed on ice and transported to Sierra Labs for analysis. Sierra Labs is a California DHS certified laboratory #1539. Each of the first ten samples was tested for total recoverable petroleum hydrocarbons, TRPH using EPA 418.1. The second set of nine samples was tested for the presence of diesel using EPA 8015M. The results are non-detect (see Tables One and Two below). Appendix B contains the Laboratory Data Sheets, Chain of Custody forms and QA/QC data.

GEOLOGICAL DESCRIPTION OF SOIL TYPE There were essentially three types of soil encountered in the excavation; 1) surface, 2) upper sand, 3) lower sand (Figure 4, Page 8). NuTECH's geologist logged the excavation as described below. » The surface material was silty fine grained sand, friable with no dry strength. There were scattered glass chips, shells and common plant roots. The sand was a moderate brown color and extended approximately one foot below the surface. » The upper sand layer consisted of fine quartz sand with about 5% dark mineral grains, low dry strength and no silt or clay. It had a uniform texture, dark reddish brown color and extended from approximately one to seven feet below the surface. » The lower sand layer also consisted of fine sand with about 5% dark mineral grains, low dry strength and no silt or clay. It had a uniform texture, moderate yel- lowish brown to moderate brown color and extended from approximately seven to twelve feet below the surface. SAMPLE NO. 1 TopsoiP: SM (silty sand), Moderate Brown (5 YR 3/4) Sand grains are fine, subangular to angular quartz; micaceous very friable, non-plastic, no dry strength. Scattered fragments of charcoal, ash, glass chips and shells (Chione SP.). Roots common. SAMPLE NO. 2 "Upper Sand": SP (poorly graded sand), Dark Reddish Brown (10 R 3/4) Sand grains are fine, subangular to subrounded quartz; about 5% dark mineral grains. Friable, non-plastic, low dry strength, uniform texture, clean (no silt or clay). SAMPLE NO. 3 "Lower Sand": SP (poorly graded sand). Moderate Brown (5 Y 4/4) when wet. Moderate yellowish brown (10 YR 5/4) when dry. Sand grains are fine, subangular to subrounded quartz; about 5% dark mineral grains. Friable, non-plastic, low dry strength, uniform texture, clean (no silt or clay). 9- 10- 11- 12 wm-•.•o-.--.---P Note: Horizontal Scale: 1" = 20' Vertical Scale : 1" = 2' Site: perachino Trust 3971 Jefferson Street Carlsbad, CA 92008 Mile; Geological Sectional Diagram Figure No.: 4 NU TECH Enterprises, Inc. V. CONCLUSIONS The following criteria were combined in an effort to assess the status of the excavation after the tank removal: * There was no visual evidence of soil contamination and the concrete storage tank has been properly rinsed and removed for recycling (Appendix C). » The laboratory data for soil samples taken from the bottom and sidewalls of the excavation confirm that no hydrocarbon contamination is present. * The concrete and reinforcing steel from the tank will be recycled. Based on the field observations and the laboratory test results, NuTECH requests a Letter of Final Site Closure — No Further Action Required. VI.
