m 1. INTRODUCTION
*• This report has been prepared by Geocon Environmental Consultants, Inc. (Geocon) in accordance
m with the request of Roger J. Holt of Ervin, Cohen & Jessup LLP (ECJ) on behalf of Western Pacific
Housing Development, L.P. (Client). The report presents the results of limited soil sampling and
analysis for the approximately 5.05-acre property located north of Aviara Parkway and adjacent to
«•the east of proposed Black Rail Road in Carlsbad, California.

1.1. Background and Purpose
«M
Aerial photograph research conducted during a Phase I Environmental Site Assessment (ESA) for
the subject site indicated that the subject site has historically been utilized for agricultural purposes
since at least 1960. The results of the ESA were presented in a report entitled Phase I Environmental
*"" Site Assessment, Buerger Property, Carlsbad, California, prepared by Geocon and dated August 14,
*" 1998. An interview with Mr. Bill Buerger, property owner, also indicated that there has been
^, historical agricultural use of the property. The property is currently occupied by two greenhouses
,_ utilized primarily for the growing of orchids and ferns. The western-most portion of the property is
utilized for the growing of Bird-of-Paradise.
According to the County of San Diego Department of Environmental Health (DEH), Site
Assessment and Mitigation (SAM) Division, soil impacted by the legal application of
pesticides/herbicides is not considered a hazardous waste assuming that the soil will not be
transported off-site, will not be treated on-site, and will not pose a threat to public health or the
environment. Substances, including some pesticides and herbicides, determined by the State of
California to be known or suspected carcinogens or to cause reproductive toxicity, are regulated in
accordance with the Safe Drinking Water and Toxic Enforcement Act of 1986, also known as
Proposition 65. The soil sampling and laboratory testing activities summarized herein were
conducted to evaluate the potential presence of organochlorine pesticides and herbicides in near-
surface soil on-site and their levels vis-a-vis the levels that constitute hazardous waste or pose a
significant risk of harm to human health under applicable law.

m 1.2. Scope of Services
* Geocon's Proposal No. LE-98132, dated August 3, 1998, is included herein as Appendix A and
m outlines the scope of services proposed for the limited soil sampling and analysis.
<•!
m 1.3. Site Location
*™ The site is located north of Aviara Parkway and adjacent to the east of proposed Black Rail Road in
«• Carlsbad, California. The site is bounded by property utilized for agricultural activity to the north
• and south; undeveloped open space area and graded property to the east; and Black Rail Road under
construction to the west. The approximate location of the site is depicted on the Vicinity Map
presented as Figure 1. A Site Plan depicting the approximate site boundaries and soil sampling
locations is included as Figure 2. The property is further identified by County of San Diego
*" Assessor's Parcel Numbers 215-040-08 and -10.

JHU 1.4. County of San Diego Department of Agriculture
<•»
During the referenced ESA, a representative of Geocon requested a search of County of San Diego
'ami
Department of Agriculture records for information concerning agriculture-related permits and
•r*violations for the site and the adjacent properties. As of the date of the ESA report, Department of
*"' Agriculture personnel had not responded to Geocon's request for information.
_, Department of Agriculture personnel have since indicated that records were available for the subject
^ site. Department personnel further indicated that records are maintained for two years prior.
Information obtained from the Department of Agriculture referenced two permits for PACIFIC RIM
FLOWERS & ORCHIDS for a flower greenhouse and outdoor flowers, respectively. The permit for
the flower greenhouse indicated that on three occasions, January 25, February 22, and March 15,
1997, 4.00 ounces of CHIPCO 26019 BRAND FUNGICIDE was applied to 0.5 acres of the
property. The permit further indicated that on May 17, 1997, 1.00 ounces of SPECTRACIDE
^ DIAZON LIQUID was applied to 1.00 acres of the property. The permit for the outdoor flowers
^ indicated that on June 15, 1997, 4.00 ounces of ROUNDUP HERBICIDE was applied to 0.50 acres
of the property. These agricultural chemicals are not regulated as carcinogens or reproductive toxins
'ani by the State of California and application of the quantities referenced do not represent a significant
"" risk to human health or the environment.

During the referenced ESA the current property owner, Mr. Bill Buerger indicated that he has owned
the property for approximately 16 years. Mr. Buerger further indicated that he has utilized the
property only for the cultivation of orchids and plants similar to those observed during the site
reconnaissance since purchasing the property. Mr. Buerger also indicated that fertilizing of the
property has also been consistent with that observed during the site reconnaissance. The fertilizer
and pesticides have been pre-mixed off-site and then pumped into the holding tank for delivery
through the watering system, or mixed in the area adjacent to the pesticide/fertilizer storage cabinet
and then piped through the watering system for the past 16 years. Although the Department of
Agriculture does not have records for the year 1998, based on the 1997 permits and information
provided by Mr. Buerger, it appears that the chemicals currently used are not regulated as
carcinogens or reproductive toxins by the State of California and do not represent a significant risk
to human health.
2. SAMPLING AND ANALYSIS
2.1. Sample Locations
*• Seven sampling locations, three biased and four random, were selected throughout the subject site.
— The biased sampling locations were selected at areas where the site reconnaissance or research had
indicated the existing or historical presence of agricultural activity and at locations where
pesticides/herbicides have been stored or handled. The approximate sampling locations are depicted
on the Site Plan, Figure 2. The three biased locations, adjacent to the northern property boundary, in
proximity to the holding tank, and in proximity to the storage cabinet, were identified as PRF1
""" through PRF3, respectively. The remaining four locations, PRF4 through PRF7 were selected at
*- random since information obtained during the referenced ESA indicated that similar agricultural
— chemicals have been applied throughout the subject site. Although sampling was conducted in the
southern greenhouse, sampling was not conducted in the northern greenhouse because both
greenhouses were subject to similar pesticide/herbicide use and the near-surface soil at both
MM
greenhouses likely contains similar residual concentrations of the chemicals used.

2.2. Summary of Field Activities
Exploratory borings PRF1 through PRF7 were advanced by representatives of Geocon on August 12,
1998, utilizing a stainless-steel hand auger. Three soil samples were obtained from each boring at
depths of approximately 0 to 6 inches, 1 to 1/2 feet, and 2 to 2!/2 feet below the ground surface with
"*"" the exception of boring PRF5 at which refusal was encountered at approximately 11A feet. The soil

samples were placed in 4-ounce glass jars, which were capped with Teflon-lined lids, labeled, and
placed in a chilled cooler for transport to a laboratory for potential analyses.
Ml Quality assurance/quality control procedures were implemented during the field activities. The
* procedures included using chain-of-custody procedures when transferring the soil samples to the
• laboratory for analyses and cleaning the hand augers in a trisodium phosphate solution followed by
«• successive rinses in tap and deionized water between sampling events.
-» 2.3. Laboratory Testing Rationale
** The 14 soil samples collected at the ground surface to approximately 6 inches and at a depth of
*• between approximately 1 to 1 '/2 feet were analyzed for the presence of organochlorine pesticides
•m following Environmental Protection Agency (EPA) Test Method 8080 and for organochlorine
^ herbicides following EPA Test Method 8150. The 6 soil samples collected at a depth of between
approximately 2 and 2l/2 feet were initially held by the laboratory for potential future analyses.
Concentrations of 4,4'-DDE, 4,4'-DDD, 4,4'-DDT, and Dieldrin were detected in the soil samples
MM
collected from six of the seven sampling locations (PRF1 through PRF3 and PRF5 through PRF7).
'** At four of the sampling locations (PRF1, PRF2, PRF5, and PRF7) the detected concentrations of
*"• certain organochlorine pesticides did not attenuate with depth. Subsequently the three soil samples
^ collected from 2 to 25/2 feet below the ground surface at the sampling locations where the detected
^ organochlorine pesticides did not attenuate with depth (PRF1, PRF2, and PRF7) were subjected to
analyses for organochlorine pesticides following EPA Test Method 8080 (PRF5 encountered refusal
M
at l'/2 feet and no sample below this depth could be tested). The three soil samples collected from 2
to 2'/2 feet below the ground surface at the sampling locations where the detected organochlorine
—' pesticides attenuated with depth to non-detect or were non-detect throughout (PRF3, PRF4, and
— PRF6) were not subjected to analyses for organochlorine pesticides since it is unlikely that a non-
-w-[ impacted middle layer would be present.
MM
Organochlorine pesticides/herbicides, as opposed to organophosphate pesticides/herbicides, were
•H
selected for analyses since, of the compounds which may have historically been applied on
agricultural crops/flowers located on and/or in proximity to the site, organochlorine compounds are
m relatively more environmentally-persistent and are more likely to be regulated by Proposition 65.
«• Based on Geocon's knowledge of the area, organophosphate pesticides/herbicides were not generally
m used historically and tend to degrade relatively quickly compared to organochlorine

— 3. DISCUSSION
,m
3.1. Proposition 65 Requirements«*
m The pesticides 4,4'-DDT, 4,4'-DDE, 4,4'-DDD, and Dieldrin are regulated by Proposition 65 as
human carcinogens. Proposition 65 prohibits a person in the course of doing business from
knowingly and intentionally exposing an individual to a chemical, known to the State to cause cancerurnor reproductive toxicity, at a concentration that poses a significant human health risk without first
^ giving that individual clear and reasonable warning. To waive this disclosure requirement,
PrqjectNo. 08853-06-02 -6- August31, 1998
PRIVILEGED AND CONFIDENTIAL
ATTORNEY-CLIENT PRIVILEGE
ATTORNEY WORK PRODUCT
SELF-EVALUATIVE PRIVILEGE
Proposition 65 regulations require that an assessment of potential adverse human health effects be
performed to determine whether potential exposures to 4,4'-DDT, 4,4'-DDE, 4,4'-DDD, and
Dieldrin would result in a significant risk to human health. If the finding of the risk assessment is
that potential exposure to 4,4'-DDT, 4,4'-DDE, 4,4'-DDD, and Dieldrin does not result in a
significant risk to human health, disclosure of the presence of the 4,4'-DDT, 4,4'-DDE, 4,4'-DDD,
and Dieldrin would not be required under applicable law. Based upon the concentrations of
organochlorine pesticides detected, such an assessment would conclude that the organochlorine
pesticides on-site do not constitute a significant risk to human health.
3.2. Waste Characterization
According to the DEH SAM Division, the impacted surficial soil would not be considered a
hazardous waste under any circumstances unless the soil is either treated on-site or is transported
off-site. If the on-site pesticide-impacted soil, i.e., the upper approximately top 3 feet of on-site soil,
is to be treated on-site or transported off-site, additional soil sampling and analyses would be
required for waste classification purposes. However, grading, moving, or placing the affected soil as
fill would not constitute treatment if the intent is not to render the soil less hazardous or non-
hazardous.
3.3. Preliminary Remediation Goals
A document issued by the EPA entitled Region 9 Preliminary Remediation Goals (PRGs), 1998 was
reviewed to compare the concentrations of pesticides detected in on-site soil to the respective PRGs
for soil in a residential setting. The PRGs are "risk-based tools for evaluating and cleaning up
contaminated sites. The EPA Region 9 (in which the site is located) PRGs combine current EPA
toxicity values with "standard" exposure factors to estimate contaminant concentrations in
environmental media (soil, air, and water) that are considered protective of humans, including
sensitive groups, over a lifetime." The PRGs are therefore conservative figures and thus "chemical
concentrations above these levels would not automatically designate a site as "dirty" or trigger
response action." However, concentrations below PRG levels would not pose a significant risk to
human health. The PRGs for DDT, DDE, DDD, and Dieldrin in soil in a residential setting are 1,700,
1,700, 2,400, and 28 ug/kg, respectively. All of the concentrations of these chemicals detected at the
subject site were less than the PRGs except for sample PRF1-2 collected at a depth of l!/2 feet which
exhibited a Dieldrin concentration of 31|ig/kg. Considering that Dieldrin was detected in only 4 of
17 samples analyzed and that sample PRF1-3 collected from the same boring at a depth of
Project No. 08853-06-02 -7- August 31, 1998

SELF-EVALUATIVE PRIVILEGE
approximately 2'/2 feet exhibited a Dieldrin concentration of only 20 Hg/kg, the concentration
detected in PRF1-1 does not constitute a "representative" exposure concentration for risk assessment
purposes.
The EPA has also established generic soil screening levels (SSLs) for the protection of groundwater.
These generic SSLs were derived using default values in standardized equations adopted by the EPA.
Two different SSLs for DDT, DDE, ODD, and Dieldrin are listed by the EPA depending on the
degree of dilution and attenuation between the source and a receptor well. However, based on the
anticipated depth to groundwater, geologic conditions, and the fact that the agricultural chemicals
were applied at the surface and not released below the ground, attenuation of the concentrations
detected to insignificant levels likely occurs at a depth that would not adversely affect groundwater
quality.

to 4. CONCLUSIONS
Based on a comparison of the concentrations of organochlorine pesticides detected with the PRGs,
** the fact that the property will be graded prior to residential development, and the general attenuation
IM of concentrations with depth combined with the anticipated depth to groundwater, the laboratory test
)to results suggest that near-surface on-site soil is not impacted by organochlorine pesticides or
herbicides at concentrations which would likely pose a significant risk to human health or threat to
^^groundwater. If export or treatment of the upper approximately 3 feet of soil, i.e. pesticide-impacted
soil, is contemplated during future development of the property, additional soil sampling and
** analyses in accordance with applicable regulations would be required for waste classification
• purposes. However, grading, moving, or placing the affected soil as fill would not constitute
pi treatment if the intent is not to render the soil less hazardous or non-hazardous. In addition,
^ additional sampling and analyses for waste classification purposes is not necessary for soil exported
from depths greater than approximately 3 feet below the existing ground surface.

PROPOSAL - LIMITED SOIL SAMPLING AND ANALYSIS
Dear Mr. Holt:
In accordance with your request on behalf of Western Pacific Housing (Client), Geocon
Environmental Consultants, Inc. (Geocon) is pleased to present this proposal to perform limited soil
sampling and analysis for the subject site. The approximately 5.05-acre subject site is located north of
Aviara Parkway and adjacent to the east of proposed Black Rail Road in Carlsbad, California. Aerial
photograph research conducted during a Phase I Environmental Site Assessment (ESA) for the subject
site indicated that the subject site has historically been utilized for agricultural purposes since at least
1960. An interview with Mr. Bill Buerger, property owner, also indicated that there has been historical
agricultural use of the property. The property is currently occupied by two greenhouses utilized
primarily for the growing of orchids and ferns. The western-most portion of the property is utilized for
the growing of Bird-of-Paradise. Residual concentrations of pesticides and/or herbicides, regulated as
chemicals known to the State of California to cause cancer or reproductive toxicity through
Proposition 65, may be present in the near-surface soil on-site.
PURPOSE AND SCOPE OF SERVICES
Based on information obtained during the referenced Phase I ESA, the following scope of work would
be performed to evaluate the potential presence of organochlorine pesticide and herbicide impacts to
near-surface soil at the subject site:
Task I - Pre-Field Activities
Prepare a Health and Safety Plan for the use of Geocon employees during the field activities. The
Health and Safety Plan would recommend levels of personal protective equipment (PPE) during the
field activities and would outline general health and safety considerations.

• At 7 random and biased sampling locations, soil samples would be collected from 0 to 6 inches
^' below the existing ground surface, approximately 1 to 1/2 feet below the existing ground surface,

collected utilizing a hand auger, transferred to laboratory-supplied glass jars, capped with Teflon-
lined lids, labeled, placed in a cooler with ice, and transported to a California Department of
*"1 Health Services (CDOHS)-certified analytical laboratory.
am
• The 14 soil samples collected from 0 to 6 inches below the existing ground surface and
*"* approximately 1 to I'/z feet below the existing ground surface would be subjected to analyses for
^ organochlorine pesticides following United States Environmental Protection Agency (EPA) Test
Method 8080, and for organochlorine herbicides following EPA Test Method 8150. Samplesgggi
collected from 2 to 2'/z feet below the ground surface would be held for potential future testing,
*•' pending the results of the initial analyses.
tftt*• Backfill the resulting hand-augered borings with the soil cuttings generated.
vt***
• Perform quality assurance/quality control procedures during the field activities. These procedures
be'
would include cleansing the sampling equipment in a trisodium phosphate solution followed by
""" successive rinses in tap and deionized water prior to each sampling effort and providing chain-of-
^ custody documentation for each sample collected and transferred to the laboratory.
mf Task III - Report Preparation
Prepare a report of the findings of the soil sampling and laboratory testing. A figure depicting the
^. locations of the borings, the results of the laboratory analyses, and the results of the quality
assurance/quality control measures would be included in the report.
