U.S. EPA, 1996, Region 9 Preliminary Remediation Goals (PRGs) 1996. Leighton and Associates, Inc. (Leighton) has completed services outlined in our proposal dated May 13, 1996 for the Legoland Carlsbad and Carlsbad Ranch Phase II sites in Carlsbad, Califomia. Rough- grading for these two sites was performed concurrently. Prior to site grading, an environmental specialist from Leighton reviewed previous environmental and geotechnical reports for the property and visually evaluated the site conditions and any changed conditions since the completion of the Phase I Environmental Site Assessment report (Leighton, 1989). During site grading , a Leighton environmental representative was on site weekly during grading to observe and evaluate any possible environmental conditions. In general, conditions during grading were as anticipated with no significant observable areas of hydrocarbon contaminated soil or other contamination being encountered. However, during grading, 3934 MURPHY CANYON ROAD, SUITE B205, SAN DIEGO, CA 92123 (619) 292-8030 • (800) 447-2626 FAX (619) 292-0771 960151-002 several large stockpiles of debris were stored on site until proper removal from site or until they were used as fill material. On May 16, 1997, a 20+ foot asbestos lined water pipe was uncovered during grading north of the intersection of Palomar Airport Road and Hidden Valley Road. The pipe was removed from the immediate grading area and placed in an area with other PVC pipe, concrete and other debris that was also uncovered during grading. All pipe debris was removed off site approximately mid-July and hauled to a local solid waste disposal site. On July 10, 1997, a leach field was uncovered near Lego Drive (40+50 marker). This area is designated to be part of the landscaping near the outer park area. A water sample was collected for visual observation. No odors or discoloration were noted. The leach field was filled with gravel and topped by 10+feet of fill soils. It should be noted that no significant hydrocarbon odors were detected during grading and no liquids were observed during the removals of PVC pipes. On September 8, 1997, at the completion of site grading, in accordance with requests of the City of Carlsbad, a Leighton environmental specialists randomly selected ten locations within the completed graded areas for the collection of 10 surface soil samples. Each soil sample was placed in a laboratory supplied sample jar and transported in an ice-cooled chest to Pacific Treatment Analytical Services, Inc. (PTAS) in San Diego, Califomia. PTAS is a Califomia certified laboratory. Each soil sample collected was chemically tested for organochlorine pesticides by EPA Method 8080. The laboratory report is presented in Appendix A. Although toxaphene is present in 6 of the 10 samples collected, these concentrations are below the U.S. EPA (1996) health risked based Preliminary Remediation Goals (PRGs) recommended for residential (400 ug/kg) and commercial (1,700 ug/kg) property use, and are not considered a constraint to site development. Please see the attached map (Figure 1) for the sample locations. The complete laboratory report is presented in Appendix A. If you have any questions regarding our letter, please contact this office. We appreciate this opportunity to be of service. Respectfully submitted, LEIGHTON AND ASSOCIATES, INC. Michael R. Stewart, CEG 1349 (Exp. 12/31/97) Thomas E.
