(CSS) presents herein, our Site Assessment Report for the subject properties (collectively, the Site). The Site Assessment was performed in accordance with our September 8, 2011 Preliminary Site Assessment Workplan and San Mateo County Environmental Health Department’s (SMCEHD’s) October 5, 2011 approval letter and addresses comments to a draft Site Assessment Report communicated by you in our telephone conversation on May 4, 2012 and subsequent emailed comments to draft versions of the Human Health Risk Assessment. The work was undertaken in response to the SMCEHD’s May 12, 2011 request for such evaluation. Background The Site consists of two parcels of land adjoining the City of South San Francisco’s (City’s) Orange Memorial Park as shown in Figure 1 Site Location Map. The two parcels, referred to as the North Parcel and South Parcel, shown in aerial view in Figures 3 and 4, are separated by the concrete lined Colma Creek channel. The Site parcels are thought to have been first developed between 1956 and 1965 by Mazzanti Carnation, Inc. as a greenhouse carnation nursery. In historical aerial photographs greenhouses can be seen occupying nearly the entire areas of the North and South Parcels, except for a small area along the southern edge of the North Parcel where farm support buildings are still present (see Figure 2). In the early 1990’s Mazzanti relocated to Pescadero, California and their property was subdivided and the two Site parcels were subsequently sold to the City. In about 2006 the City demolished the 2 greenhouses on the Site disposing of the debris. Following demolition, the City placed import fill from a vicinity construction site over the eastern half of the North Parcel. Until recently, the North Parcel was been leased out for vegetable farming however it is now vacant. The South Parcel has remained a vacant, fenced-in lot with no public access. In 2010 CSS performed a Limited Phase II Environmental Site Assessment (report dated August 4, 2010) involving the collection and analysis of surface and shallow soil samples from the Site: samples CSS-1 through CSS-5 were collected from the South Parcel in April 2010 and samples CSS-6 through CSS-10 were collected from the North Parcel in July of 2010. The Phase II identified organochlorine pesticides: Dieldrin, Chlordane and Endrin as constituents of concern (COCs) due to their presence at concentrations exceeding their respective soil Environmental Screening Levels (ESLs) for residential land use as promulgated by the California Regional Water Quality Control Board, San Francisco Bay Region. Soil sample CSS-7, with the highest concentrations of pesticides, was also tested by the California WET and found not to have the toxicity characteristics of California hazardous waste. Selected soil samples were also tested for lead which was not found at concentrations of concern. To limit potential human and environmental exposure to Site COCs, in May 2011 the City placed a cap of additional import fill from a local construction project on both the North and South Parcels. Analytical results were showing that the fill was “clean” were supplied to the City prior to their acceptance of the fill. The ground surface elevation of both parcels were surveyed prior to, and following, the placement of fill and the attached Figures 3 and Figures 4 indicate the May 2011 fill depths for the North and South Parcels, respectively. The average clean cap thickness placed over the Site in 2011 was 1.2 feet. The City recently terminated a lease for North Parcel to a vegetable farmer. The City is considering leasing the South Parcel for short time use as an urban garden, with the requirement that all gardening be done in raised beds which do not contain native soils from the property. A long term plan for both parcels is to incorporate them into Orange Park for various public recreational uses. The goals of the current Site Assessment were to investigate the lateral and vertical extent of COC impacts, assess whether groundwater has been impacted or is threatened, and perform a human health risk assessment (HHRA). 3 Current Site Assessment Activities The following tasks were completed under the current Site Assessment:  A Site Specific Health and Safety Plan was prepared prior to the implementation of field work.  Subsurface Drilling Permits were obtained from the SMCEHD for two deep borings completed to the depth of groundwater  Site utilities were cleared in the vicinity of the two deep borings by marking them and contacting Underground Service Alert (USA) and by using a private underground utility locating service.  Two deep borings, CSS-11 to 16 feet on the North Parcel and CSS-16 to 20 feet on the South Parcel, were completed on November 23, 2011 by a C-57 licensed driller using direct-push GeoProbe drilling technology. Multiple soil samples and a groundwater sample were collected from each boring.  Seven hand augered borings, CSS-12 through CSS-15 on the North Parcel and CSS-17 through CSS-19 on the South Parcel, were completed to depths of about 5 feet on December 20-21, 2011. Multiple soil samples were collected from each boring.  All borings were field logged for soil type by a California Registered Professional Civil Engineer.  22 soil samples and 2 groundwater samples were analyzed for organochlorine pesticides by EPA Method 8081A by a State-certified environmental testing laboratory.  Prepared this report summarizing our findings, conclusions and recommendations. Discussion of Results Site Lithology The surface and near surface soils of the Site consist of the imported fill cap material, this soil is borrow hauled and placed on the Site in May 2011 from subsurface excavation at a South San Francisco affordable housing construction project located at 636 El Camino Real. In the attached boring logs, it is generally described as dark brown, brown or strong brown sand with varying and largely subordinate amounts of silt, clay and gravel. On the South Parcel the cap soil is free of organics, while on the North Parcel it contains organics due to the cultivation of agriculture and is frequently described as loam. The average cap thickness is 1.2 feet. On the North Parcel the cap thickness varies from over 2 feet at the western side of the property to about 0 feet at the northeastern corner and eastern side of the property (see Figure 3). The average cap thickness on the North Parcel is 1.2 feet. On the South Parcel the cap 4 thickness varies from over 2 feet in the center of the property to about 0 at the perimeter (See Figure 4). The average cap thickness on the South Parcel is 1.3 feet. During placement of the cap fill in 2011, where the Site perimeter met the existing grade, i.e. where there was no perimeter retaining wall or embankment, no cap material was placed. On the North Parcel, prior fill material was placed by the City in 2006 on the eastern portion of the parcel to raise the grade in this area. Based on borings, the older fill on the eastern half of the North parcel was about 2 feet and is of similar description to the 2011 fill. The source of fill in 2006 was reportedly a cemetery excavation in nearby Colma. Native soils underlying recent fills consist of yellowish brown to dark yellowish brown fine sand with a trace of silt. In the two deep borings this extends to the total depth explored, 16 feet at the North Parcel and 20 feet at the South Parcel, interrupted only by a 3 to 6-inch lens of reddish brown medium sand below 10 feet and occasional deeper thin (2 to 6-inch) clay lenses interbedded with the yellowish brown sand. Groundwater was encountered within the sand at a depth of about 16 feet below the existing ground surface. Results of Laboratory Analyses Copies of the analytical reports from TestAmerica Laboratory of Pleasanton, California for samples collected from exploratory borings CSS-11 through CSS-19 in the current investigation are attached to this report. The locations of all Site borings are shown on Figure 3 for the North Parcel and Figure 4 for the South Parcel. Pesticides were not detected above laboratory reporting limits in either of the two groundwater samples collected: at CSS-11 and at CSS-16. Table 1 presents the results of detected organochlorine pesticides and lead from this and other recent investigations. Table 1 also provides the thickness of the 2011 import fill cap at the sample location and the sample depth. The sample depth indicates the starting depth of a 6-inch long soil sample, i.e. a sample collected at a depth of 2 feet extends from 2 to 2-1/2 feet in depth. Cap thicknesses were taken either from interpretation of the boring log, for samples collected in 2011, or interpolated from the pre- and post-cap elevation survey, for samples collected in 2010 prior to cap placement. Table 1 also presents three sets of residential soil contaminant screening levels for comparison to the results: the most recent California Regional Water Quality Control Board, San Francisco Bay Region, Environmental 5 Screening Levels (ESLs); US EPA Region 9 Regional Screening Levels (RSLs); and California Department of Toxic Substances Control Human Health Screening Levels (CHHSLs). These environmental screening levels are risk-based and consider the protection of human health (RSLs, CHHSLs) and additionally the protection of water resources and the environment (ESLs). Also presented is the Total Threshold Limit Concentration (TTLC) characteristic of hazardous waste in California. This Site Assessment finds that historical organochlorine pesticide use at the Site has impacted Site soils across both the North and South Parcels. In all, 11 different organochlorine pesticides have been detected in soil at the Site (with the given number of detections among the 42 total samples): Dieldrin (27 detections), Endrin (8), 4,4-DDT (26), 4,4-DDE (27) , 4,4-DDD (21), Endosulfan (1), technical Chlordane (6), alpha-Chlordane (8), gamma-Chlordane (8), beta-hexachlorobenzene (4) and Lindane (1). Of these, Dieldrin in 27 samples, Endrin in 8 samples, technical Chlordane in two samples, and Endosulfan Sulfate in one sample were found to exceed their most conservative corresponding screening level for residential soil. The maximum detected concentrations of Dieldrin is 880 ug/Kg, for Endrin it is 20 ug/Kg, for Chlordane 830 ug/Kg and Endosulfan was found at a maximum concentration of 14 ug/Kg. No compounds were found at concentrations representing a characteristic of California hazardous waste based on total concentration. For each of the four pesticides found at concentrations exceeding their respective screening levels: Dieldrin, Endrin, Chlordane and Endosulfan, a detail of ESL sub-values entitled Environmental Screening Levels Search Summary Form is attached. The Summary Form details component ESL concerns for direct exposure (human health), terrestrial ecological impacts, and leaching (drinking water and aquatic receptor protection). Many of the detections of Dieldrin, found at a range of 3.6 to 880 ug/Kg, were in excess of each of Dieldrin’s respective screening levels: the ESL (2.3 ug/Kg), the RSL (30 ug/Kg) and the CHHSL (35 ug/Kg). Details of the ESL for Dieldrin show concern for both direct exposure and leaching. Each detection of Endrin, found in 8 samples at a range of 3.0 to 20 ug/Kg, was in excess of its ESL of 0.65 ug/Kg. Details of the ESL for Endrin show a concern for terrestrial ecological impacts and leaching. Of the 6 Chlordane detections, ranging from 47 to 830 ug/Kg, two were found in excess of its ESL (440 ug/Kg) and its CHHSL (430 ug/Kg). Details of the ESL for Chlordane show concern for direct exposure. The sole detection of Endosulfan at 14 ug/Kg is in excess of its ESL (4.6 ug/Kg) due to leaching concerns. As previously noted, organochlorine pesticides were absent from groundwater, demonstrating that leaching to groundwater is not a pathway for contaminant migration. 6 Concerns for human health were further evaluated through the performance of a Human Health Risk Assessment discussed later in this Site Assessment. Pesticide contamination at the Site was first identified by CSS’s limited Phase II Environmental Site Assessment (report dated August 4, 2010). In response, the City placed a cap of import fill from a local construction project on both the North and South Parcels to limit potential human and terrestrial ecological exposure to Site COCs. This Site Assessment finds that significant organochlorine pesticide impacts are restricted to soils within 2-1/2 feet below the pre-cap ground surface. Figure 5 Conceptual Cross-Section illustrates these findings presenting the average pesticide concentrations for three depth horizons: the 2011 import fill cap soils (cap), native soils less than 2-1/2 feet below the cap (shallow native soils), and native soils greater than 2-1/2 feet below the bottom of the cap (deeper native soils). The average concentration of total pesticides in the 2011 cap material, if non-detects are assigned a value of one-half of the corresponding laboratory reporting limit, is 44 ug/Kg, with organochlorine pesticides not detected in the majority of samples. Likewise, the average concentration of total pesticides in deeper native soils is 44 ug/Kg. There were no detections of organochlorine pesticides among the six soil samples collected at a total depth greater than 4-1/2 feet. The shallow native soils contain the significant organochlorine pesticide impacts, for these soils the average concentration is 960 ug/Kg. Results of Human Health Risk Assessment A Human Health Risk Assessment (HRA) was prepared by Environmental Heath Decisions of Ladera Ranch, California using data from current and prior investigations to evaluate whether the COCs present represent an unacceptable health risk under current or future uses of the Site. The Revised Human Health Risk Assessment, Former Mazzanti Carnation Property (September 2012) is attached. The HRA was conducted by using the Regional Screening Level (RSL) calculator tool, a model which includes United States Environmental Protection Agency (USEPA) and California Environmental Protection Agency (Cal/EPA) Department of Toxic Substances Control (DTSC) risk assessment guidance [USEPA, 1989; USEPA, 2010; Cal/EPA, 1999, and DTSC, 2011]. The representative concentrations evaluated are the maximum and 95% upper confidence limit of the mean (95% UCL) concentrations of all chemicals detected at the North and South. The HRA evaluated both potential cancer and noncancer effects. 7 Exposures were evaluated for each parcel for adult park visitors, child park visitors, and outdoor construction workers, consistent with various public recreation uses under consideration by the City. In addition, for the North Parcel, an evaluation was conducted for a farming scenario, such as its most recent use, whereby the farmer is both exposed to soil and ingests fruits and vegetables grown in the soil. The HRA is conservative in the use of the maximum concentrations and the 95% UCL concentrations of all chemicals, when surface soils in fact consist of the import fill cap placed in 2011. The HRA finds that potential cancer risks and noncancer hazard values range between 2 in 1 million (2 x 10-6) and 2 in 100,000 (2 x 10-5) for public recreation uses as well as for outdoor construction workers at both the North Parcel and the South Parcel. Farming of the North Parcel is presents a cancer risk of 2 in 1000 (2 x 10-3) using the maximum chemical concentrations and 4 in 10,000 (4 x 10-4) using the 95% UCL chemical concentrations. The cancer risk is driven by the presence of organochlorine pesticides. If desired, further evaluation of this land use scenario should involve the collection an analysis of produce samples for organochlorine pesticides for comparison to Food and Drug Administration regulations pertaining to pesticide residuals in raw foods.

Until recently, the North Parcel was leased out for vegetable farming. It is now vacant. The South Parcel is a vacant, fenced-in lot with no public access. The COCs at the Site are organochlorine pesticide residues from the Site’s use by former owner Mazzanti Carnation, Inc as a greenhouse nursery. This operation started sometime between 1956 and 1965 and ended in the early 1990s. Figure 2 shows an aerial photograph of the Site from the time of Mazzanti’s operations. The most notable COCs are Dieldrin, Chlordane, Endrin and Endosulfan, whose maximum concentrations in soil exceed one or more screening levels for protection of human and environmental health in a residential setting. As such, residential use of the Site presents an unacceptable future land use based on present information. Further evaluation of the risks to human health under public recreational land use scenarios was performed through the use of an RSL calculator completion of a Human Health Risk Assessment (HRA), described herein. To limit potential human and environmental exposure to Site COCs, the City placed a cap of import fill on both the North and South Parcels in May 2011. The average cap thickness is 1.2 feet. Significant organochlorine pesticide impacts are found to be restricted to shallow native soils located within 2-1/2 feet below the pre-cap ground surface. Organochlorine pesticides are not present in Site groundwater, found at a depth of about 16 feet during this investigation, demonstrating that leaching to groundwater is not a pathway for contaminant migration. Figure 5 presents a conceptual cross section of the Site. The HRA finds that potential cancer risks range between 4 x 10-6 and 2 x 10-5 and noncancer hazard values range between 0.01 and 0.23 for Site use for public recreation by adults and children, as well as outdoor construction workers. Farming of the Site, such as was being performed until recently by a North Parcel tenant, is found to present a cancer risk ranging from 4 x 10-4 to 2 x 10-3 using the 95% UCL concentrations and maximum concentrations, respectfully. The noncancer hazard index ranges from 2.1 to 7.8 using the 95% UCL concentrations and maximum concentrations, respectfully. 9 Based on this Site Assessment, CSS recommends the following:  Future development and use of the North and South Parcels for public recreation would result in a cancer risk of less than 1 in 100,000 assuming the 95% UCL concentrations and a noncancer hazard of less than 1 to Site workers or visitors.  Farming of the North or South Parcels, whereby the farmer is both exposed to soil and ingests fruits and vegetables grown in the soil, is not an acceptable use given present information. If desired, further evaluation of this land use scenario should involve the collection an analysis of produce samples for organochlorine pesticides for comparison to Food and Drug Administration regulations pertaining to pesticide residuals in raw foods. This recommendation does not apply to self-contained raised bed gardens, which would be an acceptable use provided they do not contain existing Site soils.  Residential use of the Site was not evaluated in the HRA. Because the concentrations of several organochlorine pesticides exceed promulgated soil screening levels for residential land use, residential land use is not an acceptable land use based on present information.  With the concurrence of SMCEHD and, if necessary, the DTSC, the Site’s environmental agency case listing could be closed provided institutional controls are placed on the properties, e.g. deed restrictions prohibiting residential and farming land uses.

It should be recognized that the definition and evaluation of environmental conditions, and information provided by others either written or verbal is a difficult and inexact science. Judgments leading to conclusions and recommendations generally are made with an incomplete knowledge of the conditions present. Any opinions presented apply to site conditions existing at the time of the inspection and/or document review and those reasonably foreseeable; they cannot necessarily apply to site changes made of which the inspector/reviewer could not observe and has not had the opportunity to evaluate. Changes in the conditions of the subject property can occur with time, because of the natural process or the works of man. It is further possible that variations and/or changes in the site conditions could exist beyond the points explored for this investigation. Also, changes in environmental quality could occur sometime in the future do to variations in operating conditions, rainfall, temperature or other factors. Changes in applicable environmental, engineering and construction standards and practices can also occur as the result of legislation or from the broadening of knowledge. Accordingly, the data and documents presented in the scope of work may be invalidated, wholly or in part, by changes beyond the control of CSS Environmental Services, Inc. If the client wishes to reduce uncertainty beyond the level associated with the scope of work, CSS Environmental Services, Inc. should be notified for additional consultation. The discussion and recommendations presented in this report are based on information which may include: 1) information and data provided by third party consultants, 2) the testing performed at, or samples collected from, the site, 3) the observations of field personnel, 4) the results of laboratory analyses, 5) reports by others, and 6) interpretations of federal, state, and local regulations and/or ordinances. Any conclusions presented are based on the assumption that conditions do not deviate from those observed during the assessment. It is understood that other conditions may exist at the site that could not be identified from the limited information discovered within the scope of the assessment. The comments and recommendations should not be construed as a guarantee that all safety, health, or environmental hazards that exist at the subject site are identified in this report.
