A. Buza Corporation PO Box 8617 Rancho Santa Fe. California 92067 Subject: Mr. Buza: Limited Phase II Environmental Site Assessment Proposed Cannon Court Development APN 223-051-12 Carlsbad, California CTE Job No. 10-3715 At your request, we have performed an update limited Phase II Environmental Site Assessment (ESA) at the referenced site. The specific scope of work followed is outlined in a following section of this report entitled: "Specific Scope of Technical Activities-Update Phase II ESA." In a 1998 Phase I ESA Converse Consultants (Converse, 1998) indicated that agricultural chemicals had been used at this site. Subsequently, this firm conducted a limited Phase II Environmental Site Assessment in 1999 to evaluate the site for the presence of agricultural chemicals (CTE. 1999a). Toxaphene, also known as chlorinated camphene, was discovered to be present in surface soils at that time. Discussions of the results of that sampling are presented in the following section entitled: "Background." It appears that some grading or disturbance of the surface has occurred at the site since our earlier sampling and analyses. As a consequence a second round of sampling and analyses was conducted at this site by this firm. This latest round of work was based on the Interim Guidance for Sampling Agricultural Soils promulgated by the State of California Department of Toxic Substances Control (DTSC). This guideline provides for specific sampling volumes and analyses based on the size of the site and the suspected potential contaminants. Figure I shows the general location of the site. A list ofreferences is presented in Appendix A. BACKGROUND During the course of our geotechnical investigation at this site (CTE, I 999b ), we collected soil san1ples for environmental analysis from each of our seven geotechnical borings. Since the samples were intended to screen for the potential presence of agricultural chemicals the samples were composited into three samples before delivery to a State of California-certified environmental laboratory. The three soil samples sent to the laboratory were designated: B-1, B- 4; B-2. B-3; and, B-5, B-6, B-7. These designations were intended to clarify the borings from GEOTECHNICAL • ENVIRONMENTAL • CONSTRUCTION INSPECTION AND TESTING • CIVIL ENGINEERING • SURVEYING l Limited Phase II Environmental Site Assessment Proposed Cannon Court Development Carlsbad, California August 31. 2001 Page 2 CTE Job No. 10-3715 pwhich each composite sample came. The only constituent detected, using the selected analyses, was toxaphene. Detected concentrations ranged from 4,540 to 22.200 µg/kg. Appropriate protocols (outlined in the San Diego County, Department of Environmental Health manual) were followed to ensure the integrity of the samples. Additionally, all samples were retained in an iced cooler immediately following their collection and were delivered under chain- of-custody protocol. SPECIFIC SCOPE OF TECHNICAL ACTIVITIES -UPDATE PHASE II ESA Soil Sampling: Soil samples were collected from 15, backhoe excavated test pits at the site. The test pits were numbered consecutively Test Pit 1 through Test Pit 15 (TP-1 through TP-15). Per the DTSC guidelines the depths of sampling were generally approximately O to one feet below grade (fbg). However, selected samples were collected at depths of up to five fbg. Figure 2 shows the approximate locations of the samples collected. Before sampling the site was gridded into 15 sections (Figure 2). The samples were randomly collected from each of the sections under the supervision of an environmental geologist from CTE. As allowed under the DTSC guidelines soil samples were composited before being delivered to a State of California-certified environmental laboratory under appropriate chain-of- custody protocol. Samples were labeled Composite 1 and 2, Composite 3 and 4, Composite 5 and 6, Composite 7 and 8. Composite 9 and 10, Composite 11 and 12, Composite 13 and 14, and 15. These designations were intended to clarify the test pits from which each composite sample came. Sample depths were included on the sample labels. Environmental Laboratory Analvsis: As noted, soil samples delivered to California-certified, environmental laboratory for analysis. Per the DTSC guidelines selected samples were analyzed for organo-chlorine pesticides, lead, and CAM 17 metals. Each of the composite samples was analyzed for organo-chlorine pesticides (using EPA Method 8081A) and lead (using EPA Method 6010B). In addition. per the DTSC guidelines four samples were collected and analyzed to determine background concentrations of CAM 17 metals. Composite samples were all collected at depths of O to 1 fbg. The four samples collected and analyzed for background CAM 1 7 metals concentrations were assessed using EPA Method 6010B. The results of the environmental laboratory analyses are presented on Tables 1, 2, and 3 (attached). Reporting: This summary report. documenting the scope of activities outlined above was prepared. Included are conclusions and recommendations for this site, figures, and copies of laboratory data including Quality Assurance/Quality Control Data. F:IProjects 10-3001 to 10-4000110-3715\Rpt_Update. Limited Phase II ESA.doc Limited Phase II Environmental Site Assessment Proposed Cannon Court Development Carlsbad, California August 31. 2001 Page 3 CTEJobNo. 10-3715 RESULTS, DISCUSSION. AND CONCLUSION Laboratory Results Summarized The only constituents detected in the samples analyzed for organo-chlorine pesticides were 4. 4' - DDT and its related compounds 4,4'-DDD and 4,4'-DDE. Lead was detected in all of the analyzed samples. This was expected, as lead is a common constituent in soils. In addition, various concentrations of CAM 17 metals were also detected in the analyzed samples. Again, this was an expected result as many of these constituents are common to soils of this region. Presented in Table 1 below are the concentrations of organo-chlorine pesticides detected in the analyzed samples. Also presented are the concentrations for each of these chemicals given in the United States Region IX Environmental Protection Agency (EPA) Preliminary Remediation Goals (PRGs). The PRGs are risk-based concentrations derived from standardized equations, combining exposure information assumptions and EPA toxicity data. These guidelines are available online from the EPA website.

In all cases except one the detected concentrations were below the EPA Region IX PR Gs. However, in all cases the average concentration was less than the EPA Region IX PRGs. Therefore, none of the detected organo-chlorine pesticides were determined to be Chemicals Of Potential Concern (COPC) and a risk assessment was not deemed necessary. For CAM 17 metals, the goal was to determine which, if any, metal concentrations were sufficiently different (higher) than background such that they should be included as COPCs for health risk screening purposes. On this basis none of the detected CAM 1 7 metals was determined to be a COPC and a risk assessment was not deemed necessary. Conclusions As indicated above, it appears that some grading has occurred at the site since our earlier sampling event. Therefore, this second round of sampling was conducted to evaluate the potential presence of organo-chlorine pesticides. Concentrations of 4,4'-DDT and its related compounds (4,4'-DDD and 4,4'-DDE) were detected in some of the composited samples. However, the average detected concentrations were below the Region IX EPA PR Gs and therefore a risk assessment was not deemed to be required for this site. Concentrations of CAM I 7 metals were also determined to be present in onsite soils. However, the average detected concentrations did not exceed background CAM 1 7 metals concentrations from a similar site in the project area. Therefore, a risk assessment was not deemed to be required for this site. We conclude that the detected concentrations of organo-chlorine pesticides do not pose an unacceptable health risk for the occupants of the proposed development.
