commercial use, and borders the Lost Canyon River Trail Open Space. The Site appears to be minimally graded, is transected by an asphalt access road (Norland Drive) and does not contain any structures. The southern portion of the Site is partially located within the banks of the Santa Clara River. A tree-lined, southerly flowing, blue-line tributary of the Santa Clara River is located adjacent to the eastern border of the Site. The Site appears to be vacant and unoccupied; however, piles of construction debris from former dumping are located on-site. A Santa Clarita Valley water well (Pinetree Well 5) is located west of the Site.
State Route 14 is located immediately to the north, and the area to the south, west, and east of the Site is bordered by the Los Canyon Open Space preserve consisting of the unchanneled Santa Clara River.
FIELD ACTIVITIES
Initial field activities pertaining to this investigation were completed on May 9, 2024, in general conformance with the email workplan. EFI returned to the Site on May 16 to collect the deeper samples, which were not collected during the first mobilization.
Soil Sampling Locations
The locations of the six (6) soil excavations (SP1 through SP6) advanced as part of this assessment are presented on Figure 2. Borings SP1 through SP6 were advanced at stockpile locations throughout the Site to assess the Site for potential impacts from the construction debris piles.
Soil Sample Collection and Handling Procedures
On May 9, 2024, at each sampling location SP1 through SP6, a soil sample was initially collected at depths of 0 to 0.5 foot bgs. Hand tools (shovel and trowel) were used to excavate to the sampling depth of 0.5- feet bgs. On May 16, 2024 a deeper sample was collected similarly from each location at a depth of 1.5 feet bgs. Soil samples were collected at the designated sampling depth by retrieving a representative volume of soil from the shovel and immediately transferring the soil into pre-cleaned, laboratory-provided, glass jars. The glass jars were immediately sealed with Teflon® lined, tight fitting caps. All collected soil samples intended for VOC analysis were additionally subsampled using US Environmental Protection Agency (EPA) Method 5035 sampling methodology for VOC analysis. The soil sampling locations are shown in Figure 2.
All soil samples were labeled, recorded on a chain-of-custody form, and chilled pending transportation and submittal to Pace Analytical Laboratory (Pace) of Bakersfield, California, a State-certified analytical laboratory. Chain-of-custody documentation and protocol were maintained during sample collection through submittal to the analytical laboratory.
Following completion of soil sampling, each shallow excavation was backfilled with soil cuttings. No investigation-derived waste was generated during this investigation. Descriptions and classifications of soil encountered in the stockpiles are provided below.
Encountered Soil Types
Soil types encountered during this investigation were generally classified as well-graded Sand (USCS soil type symbol “SW”); fine to coarse grain sand; generally light brown, brown or dark brown where mixed with asphalt; loose to medium dense; dry (at surface) to moist. It should be noted that steel, polyvinyl chloride (PVC), concrete and asphalt debris were noted in location SP1; concrete chunks were additionally noted in locations SP2 and SP6; additional asphalt chunks were noted in locations SP3 and as mixed with soil in location SP5. Wooden pallets and debris were noted in location SP4. Asphalt was most prevalent in borings SP3 and SP5, which indicated brown and dark drown color. The presence of asphalt was generally recognizable in the soil making up the stockpiles and was noticeably absent in other areas. Groundwater was not encountered during our soil sampling activities. With the exception of asphalt discoloring the soil where present and mixed (i.e., locations SP5), chemical staining and/or odors were not present in any soil samples.

CHEMICAL ANALYSIS
Each of the 0.5-foot soil samples collected from borings SP1 through SP6, were analyzed for total petroleum hydrocarbons (TPH), full carbon chain analysis (TPH-cc) by EPA Method 8015B, VOCs by EPA Method 8260B and Title-22 Metals by EPA Methods 6010B/7471A. The remaining deeper soil samples collected from each location were initially placed on hold with the laboratory for potential future analysis pending results from the 0.5-foot samples. Upon receipt of the shallow soil data, the deeper soil sample collected below the most impacted shallow soil sample was analyzed.
Soil chemical analysis was completed off-site by Pace. The laboratory analytical reports are included as Appendix A
.
SOIL ANALYTICAL RESULTS
This section presents the chemical analytical results of soil sample analyses.
Petroleum Hydrocarbons in Soil
Petroleum hydrocarbons can be characterized by the length of their constituent carbon chains. Carbon C4- C12, C13-C22, and C23-C36 are commonly interpreted as gasoline (TPH-g), diesel (TPH-d), and oil (TPHo) range hydrocarbons, respectively. TPH-cc (a full carbon chain analysis) includes all the petroleum hydrocarbons C4 through C36. TPH-d and/or TPH-o were detected in each of the seven soil samples collected and analyzed from the stockpiles for this assessment. Soil analytical results for TPH-cc are included in Table 1 and summarized below:
TPH-g was not detected in any of the seven soil samples submitted for laboratory analysis. TPH-d was detected in three of the seven shallow (0.5-foot) soil samples up to a maximum concentration of 74 milligrams per kilogram (mg/kg) in sample SP5-S-0.5. TPH-d was not detected in the other four soil samples analyzed.
TPH-o was detected in all seven soil samples collected and analyzed, up to a maximum concentration of 2,400 mg/kg in sample SP5-S-0.5.
In general, exposure to contaminants in soil through dermal contact, inhalation of particulate matter, and ingestion may pose risks to human health (including cancer and non-cancer risks). To evaluate if contaminants represent a significant risk to human receptors, the detected concentrations are compared to regulatory screening levels that have been established for this purpose. Human Health Screening Levels (HHSLs) are developed using default exposure and toxicity criteria to provide conservative screening levels for cancer and non-cancer risks. Concentrations of contaminants below such screening levels are not considered to represent a significant risk to human receptors. Applicable HHSLs have been established by the EPA, the California Department of Toxic Substances Control (DTSC), and the San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) as follows:
Regional Screening Levels (RSLs) have been developed by the EPA using default exposure and toxicity criteria to provide conservative screening levels, whereby concentrations of contaminants below such levels are not considered to represent a significant risk to human receptors (including cancer and non-cancer risks). EPA publishes RSLs periodically. The most current release is dated May 2024. In general, the “Target Risk = 1E-06, Target Hazard Quotient = 1.0” RSL data set is appropriate to use.
DTSC recommends the use of alternative screening levels based on toxicity criteria reviewed by DTSC’s Human and Ecological Risk Office (HERO). DTSC-modified Screening Levels (DTSC-SLs) are updated periodically and published in Human Health Risk Assessment (HHRA) Note Number 3, DTSC-modified Screening Levels (DTSC-SLs), Release Date: June 2020 – Revised May 2022 (Note 3). For compounds that have screening criteria listed in Note 3, the DTSC-SLs are used instead of RSLs.
Technical Memorandum – Phase II Environmental Site Assessment Placerita Yard Relocation
EFI Global Project Number 045.12755
SFBRWQCB has established Environmental Screening Levels (ESLs) for HHSLs and for Leaching to Groundwater. ESLs are updated periodically, and the most recent publication is dated January 24, 2019.
ELS are used for compounds that do not have established DTSC-SLs or RSLs.
To evaluate if the TPH-d and TPH-o concentrations detected in soil represent an unacceptable risk to human receptors, the detected concentrations were compared to the ESLs for Commercial/Industrial Soil (1,200 and 180,000 mg/kg, respectively). As shown in Table 1, the detected concentrations are well below the human health screening levels. Thus, TPH-d and TPH-o detected in soil do not represent an unacceptable risk to the health of commercial occupants of the Site.
In addition to potentially impacting human health, contaminants in soil (i.e., secondary sources) also have the potential for vertical migration into groundwater bodies farther below grade. Lithologic structures between the impacted soil and the groundwater table often serve as attenuating features, which may restrict or retard vertical migration to concentrations that do not represent significant risks to groundwater. To evaluate whether the TPH concentrations detected in the soil samples from the Site represent a significant risk to groundwater quality, the concentrations were compared to the ESLs for Leaching to Groundwater, as established by the SFBRWQCB. As shown in Table 1, the detected TPH-d concentrations did not exceed the ESL of 7,300 mg/kg; no screening level for TPH-o has been established for the protection of groundwater. Thus, TPH in soil does not represent a potential threat to groundwater quality at the Site.
Additionally, a deeper soil sample (SP5-S-1.5) collected below the impacted sample with the highest concentrations (sample SP5-S-0.5) also showed concentrations below the applicable human health and groundwater screening levels.
The soil samples analyzed for this assessment did not contain TPH at concentrations exceeding existing HHSLs for the protection of human health or ESLs for the protection of groundwater. Therefore, the soil sampled in the stockpile areas does not represent a potential threat to human health or to groundwater.
Volatile Organic Compounds in Soil
As shown in Table 1, VOCs were not detected at or above their respective laboratory practical quantitation limit (PQL), therefore, VOCs in soil do not represent a significant environmental concern at the Site.
Title 22 Metals in Soil
A summary of analytical results of Title 22 Metals in soil is presented in Table 1. In general, exposure to contaminants in soil through dermal contact, inhalation of particulate matter and ingestion may pose risks to human health (including cancer and non-cancer risks). To evaluate if the detected metals in soil represent a significant risk to human receptors, the detected concentrations were compared to regulatory screening levels that have been established using default exposure and toxicity criteria to provide conservative human health screening levels for cancer and non-cancer risks. Concentrations of contaminants below such screening levels are not considered to represent a significant risk to human receptors.
RSLs have been developed by the EPA using default exposure and toxicity criteria to provide conservative screening levels, whereby concentrations of contaminants below such levels are not considered to represent a significant risk (including cancer and non-cancer risks) to human receptors. EPA publishes RSLs periodically and the most recent iteration was published in May 2024.
The California DTSC recommends the use of alternative screening levels based on toxicity criteria reviewed by DTSC’s HERO. DTSC SLs are updated periodically and published in Note 3, Release Date: June 2020 -revised May 2022. For compounds that have screening criteria listed in Note 3, the alternative screening levels are used instead of RSLs.
To evaluate if the metals detected in soil represent a significant risk to human receptors, the concentrations of metals detected in soil were evaluated against screening levels for commercial/industrial soil. None of Technical Memorandum – Phase II Environmental Site Assessment Placerita Yard Relocation
EFI Global Project Number 045.12755
the detected concentrations of metal constituents exceeded their respective commercial/industrial human health screening levels. Accordingly, the presence of metals in the soil samples collected and analyzed from the soil stockpiles are not indicative of a threat to human health nor would the detected concentrations of any metals indicate they would be classified as a hazardous waste (state or federal).
CONCLUSIONS AND RECOMMENDATIONS
EFI conducted this Phase II ESA on a portion of APN 2840-001-271, which is currently owned by the City of Santa Clarita, California, and is proposed as a replacement for the property currently occupied by Public Works' Placerita Yard (APNs 2833-005-902, -903, and -904; see Figure 2). A total of six (6) soil borings (SP1 through SP6) were advanced at dumped stockpile locations throughout the Site to facilitate the collection of soil samples to assess for shallow soil impacts resulting from the historical soil, household and construction debris dumping. The 0.5-foot soil samples collected from each boring were analyzed for TPHcc, VOCs and Title 22 Metals. A deeper sample (SP5-S-1.5) from the location with the highest concentrations observed in the shallow samples (SP5-S-0.5) was additionally analyzed for TPH-cc and VOCs. The following provide the results and EFI’s Conclusions and Recommendations:
TPH-d and TPH-o were detected at maximum concentrations of 74 mg/kg and 2,400 mg/kg in the 0.5-foot soil samples collected from stockpile SP5 (sample SP5-S-0.5). A deeper sample collected from this boring (SP5-S-1.5) was ND for TPH-g and TPH-d, and indicated a TPH-o concentration of 2,000 mg/kg. None of the detected TPH exceeds their respective ESLs for the protection of human health or groundwater.
Therefore, the detected TPH in soil is considered de minimis and is not considered a threat to human health or groundwater.
VOCs were not detected at or above the laboratory PQL in any of the samples analyzed, therefore, VOCs in soil are not a significant concern in the areas assessed.
Several Title 22 Metals were detected in the six (6) 0.5-foot soil samples analyzed, all at concentrations well below the established human health screening levels established for metals concentrations in soil or within background concentrations, therefore, the metals detected in soil during this investigation are considered background and de minimis in nature.
Based on the results of this investigation, a significant risk to human health or the environment has not been identified. However, it is obvious that dumping of construction debris including asphalt, wood, bricks, concrete, household trash, etc, has occurred at the Site and the TPH-impacted soil stockpiles will need to be properly handled and disposed. Accordingly, it is EFI’s opinion that no further investigation is warranted in regard to the historical dumping identified in the Phase I ESA as a REC. However, it is recommended that the existing stockpiles be profiled for disposal, accepted at an appropriate waste receiving facility, and that the soil stockpiles are loaded, transported and properly disposed. The laboratory data attached herein can be used to profile the stockpiled soil for disposal at an appropriate facility. Based on the sampling performed on the soil stockpiles for this assessment, the previously dumped material may be disposed under profile as regulated non-hazardous waste at an appropriate licensed receiving facility. Additionally, EFI recommends the excavation, loading and disposal activities be performed under a Soils Management Plan (SMP) prepared for the Site, for the instance that unknown or unanticipated contaminants or containers (sludge, buckets or bottles of unknown liquids, drums or other unknown containers) are encountered in the dumped stockpiles during removal.

EFI Job Number: 045.12755
1. Introduction
Impact Sciences, Inc., (referred to hereunder as the client) retained EFI Global to perform limited sampling of suspect asbestos containing materials (ACM) located on and around stockpiles of soil and construction debris located within the Project Area (See project area map in Appendix I).
The limited assessment was performed on May 9, 2024, by Joshua Everett, a DOSH Certified Asbestos Consultant (DOSH Cert No. 19-6687).
Please note that the subject property is a vacant lot, and no physical structures were present at the time of the assessment.
2. Asbestos Assessment
The purpose of this assessment was to conduct bulk sampling in order to determine the presence or absence of Asbestos Containing Material (ACM) in at the subject property. The scope of this assessment included reviewing any provided building records and/or previous investigation records, visually identifying homogeneous sample areas, collecting bulk samples of suspect ACM / ACCM, recording the friability and condition of suspect ACM/ACCM, interpreting the laboratory results, and producing a written report of findings and recommendations.
The sampling was performed in accordance with requirements of the following regulations:
Asbestos Hazard Emergency Response Act (AHERA); 40 CFR 763 Subpart E Asbestos School Hazard Abatement Reauthorization Act (ASHARA); Section 206 of the Toxic Substance Control Act
National Emissions Standards for Hazardous Air Pollutants (NESHAPS); 40 CFR 61 Subpart M.
This report is a record of activities, observations, analytical results, and recommendations performed to date.
2.1 Asbestos Results Summary
The laboratory results indicate that the materials sampled during this assessment were found to be None Detected for asbestos content.
Placertia Yard Relocation Project
Limited Asbestos Assessment
EFI Global Project Number: 045.12755
No other materials were sampled as part of this assessment.
Please refer to the Homogenous Material Sampling Table and Appendices for Materials, their locations and approximate quantities.
2.2 Methodology
All samples were collected using a clean knife, chisel or the appropriate tools. Each sample was extracted carefully so as not to disturb adjacent materials while still penetrating through all layers of the material sampled.
Each sample was sealed in the appropriately sized plastic zip lock bag and the bag then labeled with a unique identification number. The sample number, description and location were then recorded on a log and plotted on a floor plan of the structure or area. Sampling tools were cleaned after collecting each sample. Any excess dust or debris from the sample location was cleaned using a moistened cloth. Whenever possible, samples were collected from previously damaged portions of the material in order to minimize damage to the material.
A total of twenty-four (24) samples were submitted to LA Testing in South Pasadena, CA which is accredited under the NIST/NVLAP program for asbestos in bulk material by polarized light microscopy and the State of California for asbestos analysis. AIH Laboratory is NIST/NVLAP and California ELAP certified. LA Testing is located at 520 Mission Street, South Pasadena, CA 91030 and can be reached at 323-254-9960.
The analyses of the samples in this report were performed using polarized light microscopy using the EPA method 600/R-93/116. The phase abundances provided are visually estimated and expressed as percent area.
Total percentage of sample constituents may total greater than 100 due to trace amounts. The limit of detection for this analytical method is less than one percent. In multilayer samples, unless otherwise specified, the asbestos concentration is reported for the layer where asbestos is found. These results lie within the statistical limits of variability calculated for standard reference samples routinely analyzed in the laboratory. On a per sample basis, the accuracy and precision of the results depend on the type of sample and its asbestos content.
2.3 Regulatory Limits
Government agencies have promulgated different regulatory threshold levels to classify materials containing asbestos. The levels of asbestos content and the terms used to classify them differ. Listed below are the current regulatory agencies that have defined materials containing asbestos, along with the respective action levels, regulatory terminology and applicability:

2.4 Homogeneous Sample Materials Table
Homogeneous materials are defined as surfacing materials, thermal system insulation materials or miscellaneous materials that are uniform in color and texture. Homogenous sample areas are the areas where homogenous materials are located. Multiple sample locations are selected within each homogenous sample area to be a true representation of each homogenous material. Typically, a minimum of three (3) samples must be collected from each homogeneous area when sampling materials that may have variable asbestos content because it was batch mixed or applied by different contractors. High asbestos content variability is especially true of surfacing materials (sprayed-on and troweled on materials like plaster, fireproofing, acoustic ceiling, plaster) and thermal system insulation (TSI) used to insulate pipes, boilers, tanks or ducts to prevent heat loss.
As many as 9 samples may be collected of surfacing materials when they cover large surface areas.
Materials that appear to be homogeneous may in fact be different materials, installed at different times and have different material content in terms of asbestos; only laboratory testing can determine whether they are really the same homogeneous area. The below table presents the homogenous materials identified during the assessment and the asbestos content of those identified materials. The homogenous materials found to contain asbestos are listed in bold type.

2.4 Asbestos Recommendations
No recommendations regarding the material sampled during this assessment are provided in this report.
Any suspect materials, that are not identified above and may be impacted during work activities, must be presumed to contain asbestos until laboratory analysis of an adequate number of samples proves otherwise.
3.0 Limitations
The inspection and testing report is based on the condition of the subject property existing and apparent on the precise time and exact date of the inspection. Not all conditions may be apparent on the inspection and testing date due to weather conditions, inoperable systems, inaccessibility of areas of the subject property, or for other reasons.

LA Testing maintains liability limited to cost of analysis. Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not be reproduced, except in full, without written approval by LA Testing. LA Testing bears no responsibility for sample collection activities or analytical method limitations. The report reflects the samples as received. Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control criteria and met method specifications unless otherwise noted. The above analyses were performed in general compliance with Appendix E to Subpart E of 40 CFR (previously EPA 600/M4-82-020 “Interim Method”) but augmented with procedures outlined in the 1993 (”final”) version of the method. This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government. Non-friable organically bound materials present a problem matrix and therefore LA Testing recommends gravimetric reduction prior to analysis.
Unless requested by the client, building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample. Estimation of uncertainty is available on request.
