P O Box 676066 Rancho Sante Fe, Ca 92067 Subject: Limited Phase n Environmental Site Assessment Proposed Cannon Court Development APN 223-051-12 Cannon Court, Carlsbad, Califomia Mr. Buza: At your request, we have performed a limited Phase n Environmental Site Assessment (ESA) at the referenced site. Specifically, we collected near-surface soil samples for analysis at an environmental testing laboratory to evaluate the possibility that these soils contain agricultural chemicals. The use of agricultural chemicals at this site was previously identified in a Phase I ESA prepared in 1998 by Converse Consultants. Figure 1 shows the general location of the site. Soil Sampling and Analysis During the course of our geotechnical investigation at this site, we collected soil samples for environmental analysis from each of our seven geotechnical borings. The samples for environmental laboratory analysis were collected at approximately two to three feet below grade (fbg). Figure 2 shows the approximate locations of our borings. Boring logs are appended to this report. Since the samples were intended to screen for the potential presence of agricultural chemicals the samples were composited before delivery to the State of Califomia- certified Pacific Treatment Analytical Services, Inc. (PTAS) laboratory. Three soil samples were sent to the PTAS laboratory. The samples were designated as follows: B-l, B-4; B-2, B-3; and, B-5, B-6, B-7. These designations were intended to clarify the borings from which each composite sample came. Appropriate protocols (outlined in the San Diego County, Department of Environmental Health manual) were followed to ensure the integrity of the samples. Additionally, all GEOTECHNICAL AND CONSTRUCTION ENGINEERING TESTING AND INSPECTION Limited Phase II Environmental Site Assessment APN 223-051-12 Proposed Cannon Court Development, Carlsbad, Califomia December 13, 1999 Page 2 CTE Job No. 10-3715 samples were retained in an iced cooler immediately following their collection and were delivered under chain-of-custody protocol. Each sample was analyzed for: chlorinated herbicides (using EPA Method 8150) and organochlorine pesticides (using EPA Method 8081). Copies of the complete laboratory reports (including QA/QC data and chain-of-custody) are appended to this report. Laboratorv Results Presented on the Table below are the results of the laboratory testing. Listed are the constituents detected in each of the analyzed samples and their concentrations. If a constituent is not detected it is not listed on the table. For a complete list of the tested constituents please see that attached laboratory reports. If "none" appears in the constituents column this indicates that no constituents were detected at the laboratory detection limits used per the recognized laboratory protocol. For additional quality control a duplicate sample was analyzed at random. These results are also shown on the Table below. ENVIRON TABLE MENTAL LABORATORY ANALYSES Sample Designation Detected Chlorinated Herbicides and Concentrations Detected (in |ig/kg) Detected Organochlorine Pesticides and Concentrations Detected (in fxg/kg) B-l, B-4 None Toxaphene (4,540) B-l, B-4 (duplicate) None Not analyzed B-2, B-3 None Toxaphene (6,620) B-5, B-6, B-7 None Toxaphene (22,200) Interpretation and Recommendations The only constituent detected, during the selected analyses, was toxaphene. Toxaphene is also known as chlorinated camphene. It is an amber, waxy solid that decomposes with prolonged exposure to sunlight. Per the NIOSH Guide to Chemical Hazards, the exposure limits are 0.5mg/m^. These levels are several orders of magnitude greater than the expected concentrations to be encountered during constmction at this site. We anticipate that grading activities (mixing and blending of the soil) will further reduce the detected concentrations of toxaphene. Additionally, we anticipate that once constmction is complete and the project is covered with asphalt and concrete pavements that exposure of workers or customers is not expected to be a concem. Once grading is complete, we recommend that additional soil samples be collected and analyzed to determine their concentrations of toxaphene.

Examples of additional actions would include thicker concrete slabs or the placement of vapor barriers.
