Dear Mr. Beverly: This letter report documents the disposal of miscellaneous abandoned cheraicals and the excava- tion and disposal of petroleum hydrocarbon stained soiT from the property located at 3354 and 3366 Madison Street m Carlsbad, Califomia (site, Figure 1). Work was conducted in general ac- cordance with our proposal dated Febmary 22, 2002, (revised March 6, 2002) and your authorization to proceed. BACKGROUND The findmgs of Nuiyo & Moore's referenced Phase I Environmental Site Assessment Update (ESAU) for the subject site stated the following: "Abandoned waste oil and antifreeze containers were observed adjacent to the northeast wall ofthe garage structure during the site reconnaissance. An approximately 10-foot by 12-foot stained area was noted in the vicinity of the materials. An approximately 3-foot by 6-foot stained area also was noted in the unpaved driveway between the two residences. Prior to building demolition activities, the abandoned materials should be removed and properly disposed. The stained soil should be excavated, and soil samples should be collected to confirm the complete removal of contaminated soils." 5710 Ruffin Road " San Diego, California 92123 » Phone (858) 576-J 000 •• Fax (858] 576-9600 San Diego ° Irvine ° Ontario • Los Angeles • Oakland » Las Vegas • Salt Lake City ° Phoenix City of Carlsbad July 3, 2002 3354 and 3366 Madison Street, Carlsbad Project No. 104567002 OBJECTIVES The objective of the work was to remove and properly dispose of the abandoned chemicals, as weir as thc stained soil in the noted areas. CHEMICAL DISPOSAL ACTIVITIES On April 10, 2002, Ninyo & Moore contracted EFR Environmental Services Inc. (EFR) to col- lect and package the abandoned chemicals located in the exterior garage area ofthe subject site. The packaged materials included one, 5 5-gallon container of used oil fihers and oily debris, one, 55-gallon container of oily water, and one cubic yard box of miscellaneous materials, mcluding adhesives and paint. The waste containers were classified as non-hazardous waste, and were loaded and transported by EFR on May 15, 2002, to the Dome Rock hidustries facility in Quartzsite, Arizona for recycling/disposal. A copy of the Non-Hazardous Waste Manifest has been included in Attachment 1. EXCAVATION ACTIVITIES On April 11, 2002 , Ninyo & Moore contracted EFR to excavate the stained soil in the driveway and the exterior garage area ofthe site. Prior to excavation activities, the City of Carisbad con- firmed that the utilities at the site had been abandoned. EFR utilized a backhoe to excavate an area measuring approximately 12-feet-long by 7-feet- wide, to a depth of approximately 3.5 feet below ground surface (bgs), m the exterior garage area. The soil removal activities were advanced to a depth and extent where no stained or odor- ous soil was noted on the floor or sidewalls of the excavation. One confirmation soil sample was collected from each sidewall (NSW-02, ESW-02, SSW-02, and WSW-02), and one soil sample was collected from the floor ofthe excavation (EB-03.5) (Figure 2). EFR removed an approxi- mately 5-foot-long by 7-foot-wide area of stained soil in the driveway of the site, to a depth of one foot bgs. One confirmation soil sample was collected from the floor of the driveway area excavation (DWB-01) and one soil sample was collected from the stockpiled spoils (SPl) for disposal characterization. 4567002cxcavadon letter.doc City of Carlsbad 3354 and 3366 Madison Street, Carlsbad July 3, 2002 Project No. 104567002 The soil samples were submitted to Sierra Analytical Laboratory in Laguna Hills, Califomia. The confirmation soil samples were analyzed for total petroleum hydrocarbons, extended range hy^ drocarboris (TPHe) by United States Environmental Protection Agency (USEPA) method number 8015 Modified. Concentrations of TPHe were detected in samples SSW-02 and EB-03.5 at 780 and 543 milligrams per kilogram (mg/kg), respectively. Laboratory reports have been in- cluded as Attachment 2. A summary of the confirmation soil sample laboratory results is contained in Table 1.

The concentrations of TPHe detected in the confirmation soil samples were reported in the general carbon range of C24 through C32, indicating a heavy petroleimi hydrocarbon such as waste motor oil. It should also be noted that the soil sample with the highest TPHe concentration (SSW-02) and the stockpile soil sample (SP-1) were additionally analyzed for volatile organic compoimds (VOCs) by USEPA test method 8260B, and for Califomia Title 22 metals by USEPA test meth- ods 601 OB/7471. Neither VOCs nor elevated levels of metals were detected in either ofthe soil samples. 4567002excavalion letter.doc City of Carlsbad July 3, 2002 3354 and 3366 Madison Street, Carlsbad Project No. 104567002 EXCAVATION ACTIVITIES Following the excavation activities, the excavated area was backfilled with surface material scraped from the surrounding yard area and compacted with the back hoe. Soil generated from the excavation activities was stored at the site in a secure, 20-cubic-yard transport bin. Based on the laboratory analyses ofthe soil stockpile sample, the soil was classified as non-hazardous soil. On May 15, 2002, approximately 14.4 tons of non-hazardous soil was loaded and transported to Dome Rock Industries. The soil was received at the facility on May 20, 2002. A copy of the Non-Hazardous Waste Manifest is included in Attachment 1. DISCUSSION AND CONCLUSIONS The soil sample analytical results indicate that petroleum hydrocarbon contammated soil remains below and to the south ofthe garage area excavation. The concentrations of TPHe defected in the confirmation soil samples were reported in the general carbon range of C24 through C32, mdicat- ing a heavy petroleum hydrocarbon such as waste motor oil. Our review of a groundwater monitoring report for a nearby property indicated that the static groundwater level in the vicinity of the site is approximately 14 feet below ground surface, and the direction of groundwater flow is to the west-northwest. Based on the fact that heavy petro- leum hydrocarbons such as those detected at the site do not typically move rapidly through soil, and because the former residential use ofthe site suggests that relatively small amounts of these constituents were stored in this area, there is low likelihood that groundwater has been signifi- cantly impacted by this release of heavy petroleum hydrocarbons. Furthermore, the site is located west of Interstate 5, which is an area where the Regional Water Quality Control Board has ex- cepted groundwater from beneficial use designation. There are no regulatory standards for petroleum hydrocarbon cleanup levels. Regulatory agen- cies typically set cleanup standards on a case-by-case basis based on a number of variables including soil lithology, depth to groundwater, chemical constituents, concentrations, risk to health and the environment, and/or land use. Based on the chemical constituent detected (i.e., heavy petroleum hydrocarbons), the fact that neither VOCs nor elevated levels of metals were 4567002cxcavation letter.doc City of Carlsbad July 3, 2002 3354 and 3366 Madison Street, Carlsbad Project No. 104567002 detected in the two samples analyzed for these constituents, the depth to groundwater (estimated at 14 feet bgs), and the non-beneficial use groundwater designation, it is our opinion that there is a low likelihood that these cohcentrations would be of concem to a regulatory agency based on current site use. However, it should be noted that if the remaining contaminated soil is excavated and exported from the site, it would be considered a waste by the Regional Water Quality Con- trol Board and accepting disposal facility.
