EXECUTIVE SUMMARY
Apex Companies, LLC (Apex) prepared a Phase I Environmental Site Assessment (Phase I ESA) of the property located at 625 Willow Avenue, in Hercules, Contra Costa County, California (Site)1. This assessment was completed in accordance with Apex Proposal No. 21764332712 to Quarterra dated August 30, 2024. The scope of services was to prepare a Phase I ESA in a manner generally consistent with the ASTM International (ASTM) Standard Designation: E1527-21 “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process;” the U.S.

Environmental Protection Agency’s Standards and Practices for All Appropriate Inquiries (AAI), 40 Code of Federal Regulations (CFR), Part 312; and, any exceptions, deletions, or non-scope considerations identified in the proposal.

The Site consists of one parcel of land (406-070-042-6) comprising approximately 6.25 acres and is owned by Hercules Hotel Development Group, LLC. The Site is currently undeveloped characterized by open space land use and freeway corridor, as the Site is bordered by Willow Avenue to the south, Interstate 80 to the west, Highway 4 to the north, and an Interstate 80 offramp from north to east. An apparent freshwater wetland associated with a drainage tributary was observed on the northern portion of the Site with woody canopy and wetland vegetation. In summary, the Site has remained undeveloped land since 1916.

Adjoining and surrounding properties were undeveloped land prior to the development of residential, commercial, and industrial uses along Interstate 80 to the west-northwest and Highway 4 to the north beginning in the 1950s.

This assessment has revealed no evidence of recognized environmental conditions (RECs), controlled recognized environmental conditions (CRECs), historical recognized environmental conditions (HRECs), or de minimis conditions in connection with the Site.

Environmental
Conditions (HREC)
Apex did not identify HRECs associated with the Site.

De Minimis Conditions Apex did not identify de minimis conditions associated with the Site.

Vapor Migration
In general, EPA does not regulate indoor air quality except to the extent that indoor air impacts are caused by releases of hazardous substances into subsurface soil or groundwater (vapor intrusion). ASTM E1527-21 defines “migrate” and “migration” as referring to the movement of hazardous substances or petroleum products in any form, including solid and liquid at the surface or subsurface, and vapor in the subsurface. Vapor migration in the subsurface is described in ASTM E2600 – Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transaction; however, nothing in ASTM E1527-21 should be construed to require application of the ASTM E2600 standard to achieve compliance with all appropriate inquiries.

Subject to the above limitations, as part of the evaluation of the Site completed by Apex to identify RECs, the potential presence of hazardous substances or petroleum products in any form, including soil vapor, was evaluated.

Apex did not identify any RECs in connection with the Site that would likely pose a vapor migration concern.

2 Type of Concern Finding
Business
Environmental Risk
(BER)
Apex identified the following BERs associated with the Site:
• Given that the Site has been bordered by Willow Avenue to the south since at least 1939 and Interstate 80 East to Highway 4 East offramp since 1958, the possibility of aerially deposited lead (ADL) along the northern portion of the Site exists as the location of the Site is within 50 feet of the Willow Avenue Highway 80 East offramp.
• During the Site reconnaissance, non-native fill material was observed on the easement between the Site and the surrounding I-80 off ramp to the northwest and northeast. It was not clear if this non-native fill material was located on the northwest and northeast edges of the Site. Given that non-native fill material may cover the northwestern and northeastern edges of the Site, soils of the Site may contain naturally occurring asbestos (NOA).
• During the Site reconnaissance, Apex observed a concrete anchor or foundation at the southern entrance along Willow Avenue.

Concrete is considered a suspect asbestos containing material (ACM) and would need to be tested as to its asbestos content by a licensed asbestos contractor prior to the removal of the concrete anchor or foundation.

Non-ASTM
Considerations
Non-ASTM considerations were not included in this assessment's scope of services.

Significant Data Gaps Apex did not identify any significant data gaps associated with the Site.

Recommendations Given that Apex did not identify RECs at the Site, additional investigation is not recommended at this time. Due to the BERs identified on Site, testing of Site soils and the observed concrete debris will be required to manage the soil and dispose of the concrete debris prior to redevelopment.

Data Gaps Significance
Apex identified historical source gaps greater than 5-years and considers this a data gap. However, it is the Environmental Professional's opinion that based on a review of available environmental databases, historical sources, interviews, and other documentation, this data gap is not significant.

Not Significant

3 Data Gaps Significance
Apex has not received a response back from all government agencies and considers this a data gap. Based on the current and/or historical use of the Site and findings of this report, Apex does not consider this a significant data gap.

Not Significant
An environmental lien and AUL search was not provided by the User to Apex for review during this assessment and was not performed by Apex as part of the scope of services for this assessment. Based on the ASTM Standard requirements, Apex interprets the lack of environmental lien and AUL search as a data gap for this Phase I ESA. Based on the current and/or historical use of the Site and findings of this report, Apex does not consider this a significant data gap.

4 1.0 INTRODUCTION

1.1 Purpose
Apex Companies, LLC (Apex) has prepared this Phase I Environmental Site Assessment (Phase I ESA) of 6.25-Acre Undeveloped Lot (Site2) at the request of Quarterra. The purpose of this Phase I ESA is to perform all appropriate inquiries into the previous ownership and uses of the Site consistent with good commercial or customary practices for a possible property transaction involving the Site and to permit Quarterra (User) to qualify for one of the landowner liability protections as identified by the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).

1.2 Scope of Services
This project was completed in accordance with Apex Proposal No. 21764332712 to Quarterra dated August 30, 2024. The scope of services was to prepare a Phase I ESA in a manner generally consistent with the ASTM International (ASTM) Standard Designation: E1527-21 “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process,” and the U.S.

Environmental Protection Agency’s Standards and Practices for All Appropriate Inquiries (AAI), 40 Code of Federal Regulations (CFR), Part 312.

An environmental lien and/or AUL search was not included as a part of the scope of services for this assessment. As such, Apex assumes that the User of this report is evaluating this User requirement independently and will report any findings to the environmental professional.

The scope of services comprising this Phase I ESA was conducted to provide a reasonable level of investigation to identify recognized environmental conditions (RECs). As defined by ASTM E1527-21 Section 3.2.73:
"recognized environmental conditions", n - (1) the presence of hazardous substances or petroleum products in, on, or at the subject property due to a release to the environment; (2) the likely presence of hazardous substances or petroleum products in, on, or at the subject property due to a release or likely release to the environment; or (3) the presence of hazardous substances or petroleum products in, on, or at the subject property under conditions that pose a material threat of a future release to the environment.

The term is not intended to include de minimis conditions that generally do not present a threat to human health or the environment, and that generally would not be the subject of an enforcement action if brought to the attention of the appropriate government agencies. Any controlled RECs (CRECs) or historical RECs (HRECs) as defined by ASTM E1527-21 that were identified during the assessment are discussed in this report, as applicable. Definitions of key terms within ASTM E1527-21 are included in Section 12.0.

The approved scope of services did not include any non-ASTM considerations.

2. For purposes of this report, "Site" shall be synonymous with the ASTM E1527-21 definition of "subject property" (§3.2.88) - the property that is the subject of the environmental site assessment described in this practice.

5 1.3 Significant Assumptions
Apex has completed historical and environmental record searches in accordance with current ASTM standards and industry practices. The data, findings, and conclusions presented in this Phase I ESA are based upon a detailed search, review, and analysis of documents obtained, interviews performed, and observations made during the reconnaissance.

Phase I ESAs, such as the one performed at the Site, are of limited scope, are non-invasive, and cannot eliminate the potential that hazardous, toxic, or petroleum substances are present or have been released at the Site beyond what is identified by the limited scope of this Phase I ESA. In conducting the limited scope of services described herein, certain sources of information and public records were not reviewed.

It should be recognized that environmental concerns may be documented in public records that were not reviewed. No Phase I ESA can wholly eliminate uncertainty regarding the potential for RECs in connection with a property. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for RECs. No warranties, express or implied, are intended or made. The limitations herein must be considered when the user of this report formulates opinions as to risks associated with the site or otherwise uses the report for any other purpose. These risks may be further evaluated – but not eliminated – through additional research or assessment. We will, upon request, advise you of additional research or assessment options that may be available and associated costs.

1.4 Limitations and Exceptions
This report was prepared as a result of a contractual agreement that defined the approach and scope of services to be employed during the course of the investigation. The opinions and conclusions expressed in this study have been based strictly on the results of these contracted services. The scope of this Phase I ESA is intended to aid in the evaluation of RECs. The services provided by Apex should not be construed as a warranty or guarantee that no RECs exist at the Site or that all RECs have been uncovered. No conclusions are stated or implied concerning the suitability of the Site for its eventual use. This document is not intended for purposes other than those expressly set forth herein or for use by parties other than for whom it has been prepared.

As limited by the ASTM Standard for Phase I ESAs and the scope of work provided by Apex, aside from the sampling and testing of suspect asbestos-containing materials (ACMs), if applicable, this project was non-intrusive in nature and did not include any sampling or testing of soils, groundwater, surface water, or other materials. Additionally, unless specifically described in this report, the scope of work completed by Apex explicitly excluded issues that are outside the scope of ASTM E1527-21 and may constitute a business environmental risk as defined by ASTM.

ASTM Standard Practice E1527-21 recognizes inherent limitations for Phase I ESAs, including, but not limited to:
• Uncertainty Not Eliminated - No ESA can wholly eliminate uncertainty regarding the potential for RECs in connection with a Site. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for RECs, and this practice recognizes reasonable limits of time and cost.

QUA030-0313093-24013225
6 • Not Exhaustive - All Appropriate Inquiry does not mean an exhaustive assessment of a Site.

There is a point at which the cost of information obtained, or the time required to gather it outweighs the usefulness of the information and, in fact, may be a material detriment to the orderly completion of transactions.
• Level of Inquiry Is Variable - Not every Site will warrant the same level of assessment. Consistent with good commercial or customary practice, the appropriate level of environmental site assessment will be guided by the type of Site, the expertise and risk tolerance of the User, and the information developed in the course of the inquiry. • Comparison with Subsequent Inquiry - It should not be concluded or assumed that an inquiry was not All Appropriate Inquiries merely because the inquiry did not identify RECs in connection with a Site. Phase I ESAs must be evaluated based on the reasonableness of judgments made at the time and under the circumstances in which they were made. Subsequent Phase I ESAs should not be considered valid standards to judge the appropriateness of any prior assessment based on hindsight, new information, use of developing technology or analytical techniques, or other factors.
• Point in Time - The Phase I ESA is based upon conditions at the time of completion of the individual Phase I ESA elements: User's Responsibilities, Physical Setting Resources, Government Records, Historical Records, Site Reconnaissance, Owner/Operator/Occupant Interviews, Local Government Officials Interviews, and Evaluation/Reporting.

In general, EPA does not regulate indoor air quality except to the extent that indoor air impacts are caused by releases of hazardous substances into subsurface soil or groundwater (vapor intrusion). ASTM E1527-21 Section 3.2.53 defines “migrate” and “migration” as referring to the movement of hazardous substances or petroleum products in any form, including solid and liquid at the surface or subsurface, and vapor in the subsurface. Vapor migration in the subsurface is described in Guide E2600 – Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transaction; however, nothing in ASTM E1527-21 requires application of the Guide E2600 standard to achieve compliance with all appropriate inquiries.

1.5 User Reliance
This report documents the Phase I ESA of the Site performed by Apex at the explicit request and direction of Quarterra and in general accordance with ASTM E1527-21 and the US EPA Standards and Practices for All Appropriate Inquiries, 40 CFR 312. The findings, opinions, and conclusions of this Phase I ESA are for the confidential and exclusive use of Quarterra, its affiliates, employees, agents, successors, and assigns. Reliance on this report for any use or by parties other than specifically stated is prohibited without the expressed written consent of Apex and Quarterra, and such use is at the sole risk of the user.

Continued viability of this report is subject to ASTM E1527-21 Section 4.6 and Section 4.8. If the Phase I ESA will be used by a different user (third party) than the user for whom the Phase I ESA was originally prepared, the third party must also satisfy the user’s responsibilities in Section 6 of ASTM E1527-21.

Although no RECs, HRECs, or CRECs were identified, three potential impacts of concern were reported by Ground Zone. These three impacts of concern included the possibility of aerially deposited lead (ADL) along the northern portion of the Site as the location of the Site is within 50 feet of Willow Avenue and Highway 80 East to Highway 4 East offramp; the possibility of naturally occurring asbestos (NOA) located in the soils of the Site; and part of a concrete anchor or foundation was observed which may contain asbestos. Ground Zone recommended conducting soil sampling for lead and NOA within all areas planned for excavation and testing the concrete anchor or foundation for its asbestos content prior to removal.

Apex considers these three impacts of concern discussed by Ground Zone as business environmental risks (BERs).

6.1 Historical Resources Reviewed
Apex retained Environmental Risk Information Services (ERIS) to provide readily available historical sources including aerial photographs (Appendix E), fire insurance maps (Appendix F), topographic maps (Appendix G), and city directories (Appendix H) for the Site and surrounding properties. Copies of these historical sources are provided in the referenced appendices and are further discussed in the tables below.

ASTM E1527-21 Section 8.3.1 requires the Environmental Professional to evaluate historical property information and developing a history of the previous uses of the Site, adjoining properties, and surrounding area is to help identify the likelihood of past uses having led to RECs in connection with the Site. Further, ASTM requires that all obvious uses of the Site shall be identified from the present, back to the Site’s first developed use, or back to 1940, whichever is earlier. The term “developed use” includes agricultural uses and placement of fill dirt, and other uses that may not involve structures.

Apex has excluded listings from city directories that the Environmental Professional has deemed not significant to the evaluation of the Site.

21 7.0 ENVIRONMENTAL RECORDS REVIEW

7.1 Environmental Records
Consistent with ASTM E1527-21, customary and usual practices, specific scope of work terms and conditions (see Section 1.2), and contractual terms and conditions, Apex obtained and reviewed environmental databases and records to characterize the obvious and apparent uses of the Site and nearby properties. Apex retained ERIS to provide a database and record search report, provided in Appendix I. Apex has reviewed the listings pertaining to the Site and nearby properties and evaluated whether these listings should be considered RECs, CRECs, HRECs, vapor conditions, and/or de minimis conditions. RECs, CRECs, HRECs, vapor conditions, and/or de minimis conditions are also specifically listed in the Executive Summary and Section 9.0.

Based on the Environmental Professional's review of the databases and resulting opinion, only the following significant and relevant database and record search findings are included for discussion below.

Due to the volume of listings for the surrounding properties only listings which, in the opinion of the Environmental Professional, warrant discussion. The remaining listings are included in the appended database report.

Note: Names and Addresses listed in the table(s) below reflect the data imported from the ERIS report.

The ERIS report is populated by the various governmental databases. Spelling errors or incomplete information, if present, reflect the actual regulatory record; therefore, Apex did not correct these items.

7.1.1 On-Site Listings
The Site was not listed on any significant or relevant database and search records findings.

7.1.2 Surrounding Property Listings
Several properties surrounding the Site were identified in relevant or significant databases. Apex has reviewed the listings to evaluate their potential to impact the Site. Pertinent listings are summarized in the table below with details in the listing discussion table that follows.

According to the CHMIRS database, a spill of 4 gallons of diesel fuel was reported on the connector road between Interstate 80 East and Highway 4 East, which is located approximately 100 feet to the northwest of the Site, on October 2, 2010. This spill was reportedly caused by a vehicle accident and the substance flowed into a storm drain. No indication of where the storm drain released water to. Cal Trans was reported as the cleanup agency. Given Cal Trans reported as the cleanup agency and the absence of additional information regarding further investigation into this spill, Apex does not consider this diesel fuel spill a REC.

27 Orphan Facilities
Orphan facilities are those facilities that could not be mapped due to incomplete or incorrect address/ geocoding information.

The environmental database report identified a total of 22 orphan facilities.

These facilities were reviewed and determined to not be within the vicinity of the Site.

7.2 Environmental Liens and Activity and Use Limitations Search Environmental liens and Activity and Use Limitations (AULs) can commonly be found within recorded land title records (e.g., County Recorder/Registry of Deeds). The types of title reports that may disclose environmental liens and AULs include Preliminary Title Reports, Title Commitments, Condition of Title, and Title Abstracts. Chain-of-title reports will not normally disclose environmental liens or AULs that are imposed by judicial authorities may be recorded or filed in judicial records only.

Reviewing land title records for AULs and environmental liens (or judicial records where applicable) is a user responsibility. Apex notes the following:

Were the results of the User’s search for
environmental liens and AULS received?
No
Were environmental liens and AULS noted in the
User-provided search results?
No
An environmental lien and/or AUL search was not included as a part of the scope of services for this assessment. As such, Apex assumes that the User of this report is evaluating this User requirement independently and will report any findings to the environmental professional.

7.3 File Review/Public Records or Database Review Summary Per ASTM E1527-21, if the Site or any of the adjoining properties are identified on one or more of the standard environmental record sources then reasonably ascertainable pertinent regulatory files and/ or records associated with the listing should be reviewed in order to obtain sufficient information to assist in determining if a REC, CREC, HREC, or de minimis condition exists in connection with the Site. If, in the Environmental Professional’s opinion, such a review is not warranted, the justification for not conducting the regulatory file review must be provided. As an alternative, information from other sources (for example, online regulatory databases, on-site records, User provided records, records from local government agencies, interviews with regulatory officials, or interviews with other individuals knowledgeable about the Site may be reviewed.

It is the Environmental Professional's opinion that a file review is not warranted based on the following reasons: distance and/or hydrologic orientation of environmental concerns relative to the Site; known or suspected groundwater flow direction; and regulatory status.

30 9.0 FINDINGS, OPINIONS, CONCLUSIONS, AND DATA GAPS
Apex has performed a Phase I ESA of 6.25-Acre Undeveloped Lot, which is described in Section

2.0 of this report. This project was performed in general conformance with the scope and limitations of ASTM Standard Designation: E1527-21 “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process,” the USEPA’s Standards and Practices for AAI, 40 CFR, Part 312, and additional terms and conditions required by contract with Quarterra. Any exceptions to, or deletions from, this practice are described in Section 1.0 of this report.

This assessment has revealed no evidence of recognized environmental conditions (RECs), controlled recognized environmental conditions (CRECs), historical recognized environmental conditions (HRECs), or de minimis conditions in connection with the Site.

31 Type of Concern Finding
Vapor Migration
In general, EPA does not regulate indoor air quality except to the extent that indoor air impacts are caused by releases of hazardous substances into subsurface soil or groundwater (vapor intrusion). ASTM E1527-21 defines “migrate” and “migration” as referring to the movement of hazardous substances or petroleum products in any form, including solid and liquid at the surface or subsurface, and vapor in the subsurface. Vapor migration in the subsurface is described in ASTM E2600 – Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transaction; however, nothing in ASTM E1527-21 should be construed to require application of the ASTM E2600 standard to achieve compliance with all appropriate inquiries.

Subject to the above limitations, as part of the evaluation of the Site completed by Apex to identify RECs, the potential presence of hazardous substances or petroleum products in any form, including soil vapor, was evaluated.

Apex did not identify any RECs in connection with the Site that would likely pose a vapor migration concern.

Business
Environmental Risk
(BER)
Apex identified the following BERs associated with the Site:
• Given that the Site has been bordered by Willow Avenue to the south since at least 1939 and Interstate 80 East to Highway 4 East offramp since 1958, the possibility of aerially deposited lead (ADL) along the northern portion of the Site exists as the location of the Site is within 50 feet of the Willow Avenue Highway 80 East offramp.
• During the Site reconnaissance, non-native fill material was observed on the easement between the Site and the surrounding I-80 off ramp to the northwest and northeast. It was not clear if this non-native fill material was located on the northwest and northeast edges of the Site. Given that non-native fill material may cover the northwestern and northeastern edges of the Site, soils of the Site may contain naturally occurring asbestos (NOA).
• During the Site reconnaissance, Apex observed a concrete anchor or foundation at the southern entrance along Willow Avenue.

Concrete is considered a suspect asbestos containing material (ACM) and would need to be tested as to its asbestos content by a licensed asbestos contractor prior to the removal of the concrete anchor or foundation.

32 Type of Concern Finding
Non-ASTM
Considerations
Non-ASTM considerations were not included in this assessment's scope of services.

Significant Data Gaps Apex did not identify any significant data gaps associated with the Site.

Recommendations Given that Apex did not identify RECs at the Site, additional investigation is not recommended at this time. Due to the BERs identified on Site, testing of Site soils and the observed concrete debris will be required to manage the soil and dispose of the concrete debris prior to redevelopment.

Data Gaps
The ASTM Standard requires that the report identify the following: 1) obvious uses of the Site since 1940 or first development, whichever is earlier; and 2) significant “data gaps” which affect the ability of the Environmental Professional to identify RECs. A data gap by itself is not inherently significant. Apex identified the following data gaps in this assessment:

Data Gaps Significance
Apex identified historical source gaps greater than 5-years and considers this a data gap. However, it is the Environmental Professional's opinion that based on a review of available environmental databases, historical sources, interviews, and other documentation, this data gap is not significant.

Not Significant
Apex has not received a response back from all government agencies and considers this a data gap. Based on the current and/or historical use of the Site and findings of this report, Apex does not consider this a significant data gap.

Not Significant
An environmental lien and AUL search was not provided by the User to Apex for review during this assessment and was not performed by Apex as part of the scope of services for this assessment. Based on the ASTM Standard requirements, Apex interprets the lack of environmental lien and AUL search as a data gap for this Phase I ESA. Based on the current and/or historical use of the Site and findings of this report, Apex does not consider this a significant data gap.

35 12.0 TERMINOLOGY
Note: references in this section refer to ASTM E1527-21. abandoned property, n—property that can be presumed to be deserted, or an intent to relinquish possession or control can be inferred from the general disrepair or lack of activity thereon such that a reasonable person could believe that there was an intent on the part of the current owner to surrender rights to the property.
activity and use limitations (AULs), n—legal or physical restrictions or limitations on the use of, or access to, a site or facility: (1) to reduce or eliminate potential exposure to hazardous substances or petroleum products in the soil, soil vapor, groundwater, and/or surface water on the property, or (2) to prevent activities that could interfere with the effectiveness of a response action, in order to ensure maintenance of a condition of no significant risk to public health or the environment.

These legal or physical restrictions, which may include institutional and/or engineering controls, are intended to prevent adverse impacts to individuals or populations that may be exposed to hazardous substances and petroleum products in the soil, soil vapor, groundwater, and/or surface water on a property. actual knowledge, n—knowledge actually possessed by an individual who is a real person, rather than an entity. Actual knowledge is to be distinguished from constructive knowledge that is knowledge imputed to an individual or entity.
adjoining properties, n—any real property or properties the border of which is contiguous or partially contiguous with that of the Site, or that would be contiguous or partially contiguous with that of the Site but for a street, road, or other public thoroughfare separating them. aerial photographs, n—photographs taken from an aerial platform with sufficient resolution to allow identification of development and activities.
all appropriate inquiries, n—that inquiry constituting all appropriate inquiries into the previous ownership and uses of the Site consistent with good commercial and customary practice as defined in CERCLA, 42 U.S.C. § 9601(35)(B) and 40 C.F.R. Part 312, that will qualify a party to a commercial real estate transaction for one of the threshold criteria for satisfying the LLPs to CERCLA liability (42 U.S.C. §§ 9601(35)(A) & (B), § 9607(b)(3), § 9607(q), and § 9607(r)), assuming compliance with other elements of the defense.
approximate minimum search distance, n—the area for which records must be obtained and reviewed pursuant to Section 8 subject to the limitations provided in that section. This may include areas outside the Site and shall be measured from the nearest Site boundary. This term is used in lieu of radius to include irregularly shaped properties.
bona fide prospective purchaser [42 U.S.C. § 9607(r)], n—a person may qualify as a bona fide prospective purchaser if, among other requirements, such person made “all appropriate inquiries into the previous ownership and uses of the facility in accordance with generally accepted good commercial and

6.25-Acre Undeveloped Lot
Hercules, California
January 8, 2025
QUA030-0313093-24013225
36 customary standards and practices.” Knowledge of contamination resulting from all appropriate inquiries would not generally preclude this liability protection. A person must make all appropriate inquiries on or before the date of purchase. The facility must have been purchased after January 11, 2002.

Brownfields Amendments, n—amendments to CERCLA pursuant to the Small Business Liability Relief and Brownfields Revitalization Act, Pub. L. No. 107 - 118 (2002), 42 U.S.C. § 9601 et seq. building department records, n—those records of the local government in which the Site is located indicating permission of the local government to construct, alter, or demolish improvements on a property. business environmental risk (BER), n—a risk which can have a material environmental or environmentally – driven impact on the business associated with the current or planned use of commercial real estate, not necessarily related to those environmental issues required to be investigated in this practice. Consideration of BER issues may involve addressing one (or more) non-scope considerations. commercial real estate, n—any real property except a dwelling or property with no more than four dwelling units exclusively for residential use (except that a dwelling or property with no more than four dwelling units exclusively for residential use is included in this term when it has a commercial function, as in the construction of such dwellings for profit). This term includes but is not limited to undeveloped real property and real property used for industrial, retail, office, agricultural, other commercial, medical, or educational purposes; property used for residential purposes that has more than four residential dwelling units; and property with no more than four dwelling units for residential use when it has a commercial function, as in the building of such dwellings for profit. commercial real estate transaction, n—a transfer of title to or possession of real property or receipt of a security interest in real property, except that it does not include transfer of title to or possession of real property or the receipt of a security interest in real property with respect to an individual dwelling or building containing fewer than five dwelling units, nor does it include the purchase of a lot or lots to construct a dwelling for occupancy by a purchaser, but a commercial real estate transaction does include real property purchased or leased by persons or entities in the business of constructing or developing dwelling units. construction debris, n—concrete, brick, asphalt, and other such building materials discarded in the construction of a building or other improvement to property. contaminated public wells, n—public wells used for drinking water that have been designated by a government entity as contaminated by hazardous substances (for example, chlorinated solvents) or petroleum products, or as having water unsafe to drink without treatment. contiguous property owner [42 U.S.C. § 9607(q)], n—a person may qualify for the contiguous property owner liability protection if, among other requirements, such person owns real property that is contiguous to, and that is or may be contaminated by hazardous substances from other real property that is not owned by that person. Furthermore, such person conducted all appropriate inquiries at the time of acquisition of the Site and did not know or have reason to know that the Site was or could be contaminated by a release or threatened release from the contiguous property. The all appropriate inquiries must not result in knowledge of contamination. If it does, then such person did “know” or “had reason to know” of contamination and would not be eligible for the contiguous property owner liability protection.

QUA030-0313093-24013225
37 controlled recognized environmental condition, n—recognized environmental condition affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place subject to implementation of required controls (for example, activity and use limitations or other property use limitations).
data failure, n—failure to achieve the historical research objective in 8.3.1 even after reviewing the standard historical resources in 8.3.4.1 through 8.3.4.8 that are reasonably ascertainable and likely to be useful. Data failure is one type of data gap.
data gap, n—a lack of or inability to obtain information required by this practice despite good faith efforts by the environmental professional to gather such information. Data gaps may result from incompleteness in any of the activities required by this practice, including, but not limited to, site reconnaissance (for example, an inability to conduct the site visit), and interviews (for example, an inability to interview the key site manager, regulatory officials, etc.). See 12.6.
de minimis condition, n—a condition related to a release that generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. A condition determined to be a de minimis condition is not a recognized environmental condition nor a controlled recognized environmental condition. demolition debris, n—concrete, brick, asphalt, and other such building materials discarded in the demolition of a building or other improvement to a property. drum, n—a container (typically, but not necessarily, holding 55 gal (208 L) of liquid) that may be used to store hazardous substances or petroleum products.
dry wells, n—underground areas where soil has been removed and replaced with pea gravel, coarse sand, or large rocks. Dry wells are used for drainage, to control storm runoff, for the collection of spilled liquids (intentional and nonintentional), and wastewater disposal (often illegal). due diligence, n—the process of inquiring into the environmental characteristics of commercial real estate or other conditions, usually in connection with a commercial real estate transaction. The degree and kind of due diligence vary for different properties, and differing purposes. dwelling, n—structure or portion thereof used for residential habitation. engineering controls, n—physical modifications to a site or facility (for example, capping, slurry walls, or point of use water treatment) to reduce or eliminate the potential for exposure to hazardous substances or petroleum products in the soil or groundwater on a property. Engineering controls are a type of activity and use limitation (AUL).

38 environmental compliance audit, n—the investigative process to determine if the operations of an existing facility are in compliance with applicable environmental laws and regulations. This term should not be used to describe this practice, although an environmental compliance audit may include an environmental site assessment or, if prior audits are available, may be part of an environmental site assessment.
environmental lien, n—a charge, security, or encumbrance upon title to a property to secure the payment of a cost, damage, debt, obligation, or duty arising out of response actions, cleanup, or other remediation of hazardous substances or petroleum products upon a property, including (but not limited to) liens imposed pursuant to CERCLA 42 U.S.C. §§ 9607(1) & 9607(r) and similar state or local laws. environmental professional, n—a person meeting the education, training, and experience requirements as set forth in 40 C.F.R. § 312.10(b). For the convenience of the reader, this section is reprinted in Appendix X2. The person may be an independent contractor or an employee of the user. environmental site assessment (ESA), n—the process by which a person or entity seeks to determine if a subject property is subject to recognized environmental conditions. At the option of the user, an environmental site assessment may include more inquiry than that constituting all appropriate inquiries or, if the user is not concerned about qualifying for the LLPs, less inquiry than that constituting all appropriate inquiries. An environmental site assessment is both different from and often less rigorous than an environmental compliance audit.

ERNS list, n—EPA’s emergency response notification system list of reported CERCLA hazardous substance releases or spills in quantities greater than the reportable quantity, as maintained at the National Response Center. Notification requirements for such releases or spills are codified in 40 C.F.R. Parts 302 and 355.
fill dirt, n—dirt, soil, sand, or other earth, that is obtained off - site, that is used to fill holes or depressions, create mounds, or otherwise artificially change the grade or elevation of real property.

RCRA is sometimes also identified as the Solid Waste Disposal Act. RCRA defines a hazardous waste, at 42 U.S.C. § 6903, as: “a solid waste, or combination of solid wastes, which because of its quantity, concentration, or physical, chemical, or infectious characteristics may: (A) cause, or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness, or (B) pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed.” hazardous waste/contaminated sites, n—sites on which a release has occurred, or is suspected to have occurred, of any hazardous substance, hazardous waste, or petroleum products, and that release or suspected release has been reported to a government entity. historical recognized environmental condition, n—a previous release of hazardous substances or petroleum products affecting the Site that has been addressed to the satisfaction of the applicable regulatory authority or authorities and meeting unrestricted use criteria established by the applicable regulatory authority or authorities without subjecting the Site to any controls (for example, activity and use limitations or other property use limitations). A historical recognized environmental condition is not a recognized environmental condition. For examples of historical recognized environmental conditions, see Appendix X4.

IC/EC registries, n—databases of institutional controls or engineering controls that may be maintained by a federal, state, or local environmental agency for purposes of tracking sites that may contain residual contamination and AULs. The names for these may vary from program to program and state to state, and include terms such as, but not limited to the following: Declaration of Environmental Use Restriction database (Arizona), Land Use Restriction Sites (California Department of Toxic Substances Control), Sites with Deed Restrictions (California State Water Resources Control Board), Environmental Covenant List (Washington), Sites With Environmental Covenants and Use Restrictions (Colorado), Institutional Control Registry (Indiana), Environmental Site Tracking and Research Tool (Missouri), and the Pennsylvania Activity and Use Limitation (PA AUL) Registry.
innocent landowner [42 U.S.C. §§ 9601(35) & 9607(b)(3)], n—a person may qualify as one of three types of innocent landowners: (1) a person who “did not know and had no reason to know” that contamination existed on the Site at the time the purchaser acquired the Site; (2) a government entity which acquired the Site by escheat, or through any other involuntary transfer or acquisition, or through the exercise of eminent domain authority by purchase or condemnation; or, (3) a person who “acquired the facility by inheritance or bequest.” To qualify for the innocent landowner defense, such person must have made all appropriate inquiries on or before the date of purchase. Furthermore, the all appropriate inquiries must not have resulted in knowledge of the contamination. If it does, then such person did “know” or “had reason to know” of contamination and would not be eligible for the innocent landowner defense. See Appendix X1 for the other necessary requirements that are beyond the scope of this practice.

40 institutional controls (IC), n—a legal or administrative mechanism (for example, “deed restrictions,” restrictive covenants, easements, or zoning) on the use of, or access to, a site or facility to (1) reduce or eliminate potential exposure to hazardous substances or petroleum products in the soil or groundwater on the property, or (2) to prevent activities that could interfere with the effectiveness of a response action, in order to ensure maintenance of a condition of no significant risk to public health or the environment. An institutional control is a type of activity and use limitation (AUL). interviews, n—those portions of this practice that are conducted to gather information from an individual or individuals in person, by telephone, in writing, or via other electronic media to meet the objectives of this practice.
key site manager, n—the person identified by the owner or operator of a Site as having good knowledge of the uses and physical characteristics of the Site. See 10.5.1. land title records, n—records that affect the title of real estate, which may include, among other things, deeds, mortgages, leases, land contracts, court orders, easements, liens, and AULs recorded within the recording systems or land registration systems created by state statute in every state and ordinarily administered in the local jurisdiction (usually the county) in which the Site is located, and available by performing a title search. Such records are publicly accessible, though the process of performing a title search to find land title records often requires specialized expertise or knowledge of the local system (see

5.4 – AULs and Environmental Liens in Land Title Records). Information about the title to the Site that is filed or stored in any place other than where land title records are, by law or custom, recorded for the local jurisdiction in which the Site is located, are not considered land title records. landfill, n—a place, location, tract of land, area, or premises used for the disposal of solid wastes as defined by state solid waste regulations. The term is synonymous with the term solid waste disposal site and is also known as a garbage dump, trash dump, or similar term. landowner liability protections (LLPs), n—a defense to CERCLA available to bona fide prospective purchasers, contiguous property owners, and innocent landowners. See 42 U.S.C. §§ 9601(35)(A), 9601(40), 9607(q), and 9607(r).
local government agencies, n—those agencies of municipal or county government having jurisdiction over the Site. Municipal and county government agencies include but are not limited to cities, parishes, townships, and similar entities.
local street directories, n—directories published by private or government entities that list the occupant(s) of a specific address at the time the occupant data were collected, typically within a year of the publication date of the directory.
major occupants, n—those tenants, subtenants, or other persons or entities each of which uses at least 40 % of the leasable area of the Site or any anchor tenant when the Site is a shopping center. material safety data sheet (MSDS), n—see safety data sheet.

QUA030-0313093-24013225
41 material threat, n—obvious threat which is likely to lead to a release and that, in the opinion of the environmental professional, would likely result in impact to public health or the environment. An example might include an aboveground storage tank system that contains a hazardous substance and which shows evidence of damage. The damage would represent a material threat if it is deemed serious enough that it may cause or contribute to tank integrity failure with a release of contents to the environment. migrate/migration, v/n—for the purposes of this practice, “migrate” and “migration” refers to the movement of hazardous substances or petroleum products in any form, including, for example, solid and liquid at the surface or subsurface, and vapor in the subsurface.

National Priorities List (NPL), n—list compiled by EPA pursuant to CERCLA 42 U.S.C. § 9605(a)(8)(B) of sites with the highest priority for cleanup pursuant to EPA’s Hazard Ranking System. See 40 C.F.R. Part 300.

QUA030-0313093-24013225
42 pits, ponds, or lagoons, n—manmade or natural depressions in a ground surface that are likely to hold liquids or sludge containing hazardous substances or petroleum products. The likelihood of such liquids or sludge being present is determined by evidence of factors associated with the pit, pond, or lagoon, including, but not limited to, discolored water, distressed vegetation, or the presence of an obvious wastewater discharge.
practically reviewable, adj—information that is practically reviewable means that the information is provided by the source in a manner and in a form that, upon examination, yields information relevant to the Site without the need for extraordinary analysis of irrelevant data. The form of the information shall be such that the user can review the records for a limited geographic area. Records that cannot be feasibly retrieved by reference to the location of the Site or a geographic area in which the Site is located are not generally practically reviewable. Most databases of public records are practically reviewable if they can be obtained from the source agency by the county, city, zip code, or other geographic area of the facilities listed in the record system. Records that are sorted, filed, organized, or maintained by the source agency only chronologically are not generally practically reviewable. Listings in publicly available records which do not have adequate address information to be located geographically are not generally considered practically reviewable. For large databases with numerous records (such as RCRA hazardous waste generators and registered underground storage tanks), the records are not practically reviewable unless they can be obtained from the source agency in the smaller geographic area of zip codes. Even when information is provided by zip code for some large databases, it is common for an unmanageable number of sites to be identified within a given zip code. In these cases, it is not necessary to review the impact of all of the sites that are likely to be listed in any given zip code because that information would not be practically reviewable. In other words, when so much information is generated that it cannot be feasibly reviewed regarding its impact on the Site, it is not practically reviewable. property, n—real property, including buildings and other fixtures and improvements located on and affixed to the land.

1.0 INTRODUCTION
Ground Zone Environmental Services, LLC. (Ground Zone) is pleased to present this Phase I Environmental Site Assessment (Phase I) for Contra Costa County Assessor’s Parcel Number 406 070 042, California (Site) to Hercules Hotel Development (HHD). The purpose of the proposed development Project is to implement building and Site maintenance, building system upgrades and capital improvements (Project).

This Phase I was performed to assess recognized environmental conditions at the Site for potential future real estate transaction. This Phase I provides preliminary information on potential environmental liabilities associated with historic and current operations at the Site.

This Phase I was conducted by Ground Zone in accordance with its Scope of Work for Consultant Services to Address California Environmental Quality Act (CEQA) Requirements for Hercules Hotel Complex (Ground Zone, December 5, 2019) and in accordance with the following industry standards and regulations:
 ASTM Standard E1527-13 (Standard Practice for Environmental Site Assessments:

Phase I Environmental Site Assessment Process)1
;
 40 Code of Federal Regulations, Part 312;
 22 California Code of Regulations §69200; and,
 California Health and Safety Code §25570.2 (f).

The purpose of this Phase I report is to assess the potential risks posed by hazardous materials at the Project area to environmental resources and human health, and to Site for the presence of Recognized Environmental Conditions (RECs) as defined by American Society of Testing and Materials (ASTM) E1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. ASTM E1527-13 defines a REC as the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property. The term includes hazardous substances or petroleum products even under conditions in compliance with laws. The term REC is not intended to include de minimis conditions that generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies.

Two additional types of RECs are included in the revised ASTM publication, including Historical RECs (HREC) and Controlled RECs (CREC). An HREC is defined by ASTM E1527- 13 as a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority, or meeting unrestricted-use criteria established by the regulatory authority without subjecting the property to any required controls. A CREC is defined by ASTM as an REC resulting from a past release of any hazardous substances or petroleum products that was addressed to the satisfaction of the applicable regulatory authority (as evidenced by a no further

action [NFA] letter or equivalent, or meeting risk-based criteria established by the regulatory authority) with hazardous substances and/or petroleum products allowed to remain in place subject to the implementation of required controls (i.e. property-use restrictions, activity and use limitations (AULs), institutional controls, or engineering controls).

As part of the Phase I, an all appropriate inquiries (AAI) was conducted in accordance with the U.S. Environmental Protection Agency “Standards and Practices for All Appropriate Inquiries” (40 CFR Part 312.20). The AAI must be included as part of the process of evaluating a property’s environmental conditions and assessing potential liability for any contamination. The intention of the Phase I is to identify potential issues that may impact the Project with respect to the range of contaminants within the scope of Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) (42 U.S.C. 9601) and petroleum products.

The approach adopted by Ground Zone to meet this objective includes:
 A review of historical land use information, interviews and a survey with the property manager/owner in order to confirm current and previous land uses;  A database search to evaluate the nature of hazardous material use at the Site and the likelihood of hazardous material impact to the Site; and,  A Site reconnaissance which included a review of the Site and surrounding properties to confirm the presence and location of RECs or HRECs at the Site or nearby sites identified within the database.

2.0 BACKGROUND INFORMATION
Background information considered relevant to this Phase I includes a Project description, Site description, physical setting, and the Site geology and hydrogeology.

2.1 Project Description
Hercules Hotel Development LLC plans to construct a 100-unit 4-story hotel and s 6-story office building complex at the Site. The Site location is showed in Figure 1 and the Site plan is shown in Figure 2.

2.2 Site Description
The subject Property is located in the City of Hercules along the east side of Interstate Highway 80 (I-80) within the loop ramp to westbound Willow Avenue. The highway itself was constructed circa 1958 or during the window (1950-1958). Before this, the Property was part of open rolling hills with an intermittent channel/drainage swale, apparently the remnant of the historic tributary to Refugio Creek to the South.

The Site layout is shown in Figure 2.

2.3 Physical Setting
The subject Site is located in the northeasterly portion of the San Francisco Bay area near the City of Richmond on San Pablo Bay and in the city limits of Hercules in Contra Costa County, California. This Site encompasses the location of the Hercules Hotel Complex property that included approximately 8.5 acres of rolling hill and drainage ditch waterway terrain within the Refugio Creek Valley (Figure 3). This low-lying valley trends in a westerly-easterly direction and is in the proximity where Refugio Creek discharges its intermittent flows into the San Pablo Bay.

2.3.1 Topography
The United States Geological Survey (USGS) 2018 7.5-Minute Topographic Quadrangle Map of Mare Island, California was provided is shown in Figure 3. The average elevation of the Project area is approximately 65 ft. above mean sea level (AMSL).

The regional drainage is moderately sloped from east to west with a topographic flow direction to the west, as indicated in the Project’s Radius Map Report with GeoCheck (Environmental Data Resources [EDR] 2019) (see Appendix A).

2.1.2 Regional Geology
The Site is located within the Refugio Creek Valley a land feature sloping easterly to westerly covered mostly by exposed Quaternary aged alluvium, estuarine sediments, and manmade artificial fill materials. Older Tertiary aged bedrock underlies these younger sediments and consists of sandstones and shale - both being low to intermediate grade metamorphic units.

Bedrock located to the north is composed of Briones Sandstone and Hercules Shale. These sandstones are mostly massive and indurated by heat, and therefore lacking significant fracturing. Shale consists of closely fractured siltstone and claystone with interbedded lenses of sandstone with local fracturing.

The sandstones are covered by Tertiary gravels, sand and clayey materials in upland areas located northerly of the valley. Characteristics of the bedrock located to the south of the Site includes older Hambre Sandstone overlain by younger Rodeo Shale. In this area the sandstone is massive to thickly bedded and moderately to closely fractured. The Shale is also closely fractured but thinly bedded. These materials underlie the low grassy hills located immediately adjacent to the valley.

The bedrock underlying the valley is overlain by highly plastic silty clays mixed with varying amounts of organics and sand lenses. These materials represent a portion of the bay muds also exposed at the surface on tidal flats located to the north and are between 10 to 40 feet thick.

Across the Site materials exposed at the surface are composed of alluvium and manmade fill between 5 to 10 feet thick. Fill is moderately to well compacted engineered material composed of gravel, sand and fines with varying amounts of organic material. Alluvium consists mostly of fine-grained clay and silt with varying amounts of clayey sand and minor lenses of well sorted sands and gravels. At the surface these materials are soft or loose but become more compact and denser with increasing depth.

The Regional Geologic Map provided in Appendix B, Geologic Map of California, Santa Rosa Sheet (Koenig 1963).

The Radius Map Report with GeoCheck (EDR 2019) also provided geologic information in the general area of the Project corridor, which was identified as a stratified sequence of the Cenozoic era, quaternary system and series.

2.3 Geology and Hydrogeology

2.3.1 Local Geology and Soils
The subsurface soils in the Project area generally consist of marine and non-marine continental sedimentary rocks. Pleistocene-Holocene-aged alluvium consists of unconsolidated and semi consolidated fine-grained sediments. The unconsolidated sediments consist of clays, silts, and sands, with a thickness ranging up to 1,000 feet or more. These sediments are semi-continuous throughout the Bay and are usually referred to as “Old Bay Mud.” Younger, fine-grained alluvial and estuarine deposits (Young Bay Mud) overlay the Old Bay Mud. The younger, fine-grained alluvium is typically a mixture of interbedded stiff clays, silts, gravel, and sands derived from the hills or deposited during the formation of the San Francisco Bay.

The Radius Map Report with GeoCheck (EDR 2019) (Appendix A) provided native soil composition information in the general area of the Project corridor, which was identified as Sehorn clay comprised of Class D very slow infiltrating soils with high water table; the soils are clay from 0-25 inches, silty clay from 25 to 35 inches, and unweathered bedrock at 38 inches.

Also use Web Soil Survey.

The other major soil type identified was Clear Lake clay comprised of clay from 0 to 59 inches with very slow infiltration rates, high water table, and poorly drained. The last soil type identified is Tierra loam, also Class D and moderately well drained with loam from 0 to 25 inches, clay from 25 to 59 inches, and silty clay loam from 59 to 70 inches.

Natural Resources Conservation Service’s (NRCS) January 6, 2010 Web Soil Survey confirms soil type Clear Lake clay with 0 to 15 percent slopes, covers 1.5 acres of the Site or 15.5 percent; and Sehorn clay with 15 to 30 percent slopes covering 8 acres of the Site or 84.5% of the site. (NRCS 2020). NRCS Web Soil Survey is provided in Appendix C.

2.3.2 Naturally Occurring Asbestos
Naturally Occurring Asbestos (NOA) is present all over the state of California — the state rock serpentine contains NOA. Asbestos minerals belong to either the serpentine mineral group or the amphibole mineral group. The most common type of asbestos found in California is chrysotile, a serpentine mineral. A review of the General Location Guide for Ultramafic Rocks in California – Areas Likely to Contain Naturally Occurring Asbestos (California Geological Survey [CGS] 2000) indicated that NOA was not mapped on, or in the near vicinity of, the Project area.

However, because the Site was observed to contain large stockpiles of fill soil from an unknown source, NOA remains a risk at the Site due to regional NOA geology. (See Appendix B for Geology Map).

2.3.3 Surface and Groundwater Hydrology
Hydrology and hydrogeology located across and beneath the property is mainly a function of climatic fluctuations within the Refugio Creek watershed area and tidal fluctuations of the San Francisco Bay. The Project area is located within the San Pablo Creek-Frontal San Pablo Bay Estuaries watershed and the Pinole Creek-Frontal San Pablo Bay Estuaries subwatershed. The site receives19.36 inches of rain per year on average (Caltrans 2020).

Intermittent flows within the Refugio Creek channel located along the northerly side of the valley are directed in a westerly direction from elevated terrain located to the east. Most of these waters are emptied into San Pablo Bay to the west of the Site but small portions do infiltrate into the subsurface thus adding to underlying ground water resources. During the winter season portions of surface water flows pond in low lying depressions, artificial surface dikes, drainage ditches, and channels through the valley. Past measurements of ground water depth and gradient indicate that its direction of flow generally follows the topography of the surrounding highland features and floor of the valley westerly (Geosolutions 2003).

Underlying bedrock appears to have both a low primary permeability and highly variable secondary permeability that is due mostly to fractures. Across the Site and within the valley area, ground water in the bedrock arrives mostly after infiltrating through overlying alluvium that has been placed by erosional processes. In elevated terrain located to the east of the site, ground water enters the subsurface through the mantle of regolith located across the ground surface.

Overall these ground waters migrate in a westerly direction towards and into the bay. Within limits of the Refugio Creek valley the ground water becomes increasingly brackish to saline from south to north and east to west with the highest concentration being near to the San Pablo Bay (Geosolutions 2003).

The East Bay Plain sub-basin is a northwest trending alluvial plain bounded on the north by the San Pablo Bay, on the east by Franciscan Basement rock, on the south by the Niles Cone Groundwater Basin, and on the west by the San Francisco Bay (DWR 2004). The East Bay Plain sub-basin extends beneath the San Francisco Bay to the west (DWR 2004).

The East Bay Plain sub-basin aquifer system consists of unconsolidated sediments from of Quaternary age (DWR 2004). Deposits include the early-Pleistocene Santa Clara Formation, the late-Pleistocene Alameda Formation, the early-Holocene Temescal Formation, and Artificial Fill (DWR 2004). The Santa Clara Formation consists of alluvial fan deposits inter-fingered with lake, swamp, river channel, and floodplain deposits (DWR 2004). The Alameda Formation includes a sequence of alluvial fan deposits bounded by mud deposits on the top and bottom of the formation (DWR 2004). The Temescal Formation is an alluvial deposit consisting primarily of silts and clays with some gravel layers (DWR 2004). Artificial Fill is found mostly along the bay front and wetlands areas and is derived primarily from dredging, as well as quarrying, construction, demolition debris, and municipal waste (DWR 2004).

The depth to groundwater near the Project area ranges from approximately 3.75 ft to 10.2 ft below ground surface (bgs), and shallow groundwater flow direction is typically to the northwest (SWRCB 2018). Regional groundwater flows are estimated to be west-northwest toward the San Pablo Bay located approximately 1.5 miles west of the Project area. The Radius Map Report

with GeoCheck (EDR 2019) identified no monitoring wells, federal USGS wells, public water supply wells, or state wells within 1 mile of the Project area.

It is important to note that groundwater flow direction can be influenced locally and regionally by the presence of local wetland features, surface topography, recharge and discharge areas, horizontal and vertical inconsistencies in the types and location of subsurface soils, and proximity to water pumping wells. Additionally, the depth and gradient of the Project area’s water table can change seasonally in response to variation in precipitation and recharge, and over time, in response to urban development such as stormwater controls, impervious surfaces, pumping wells, dewatering, seawater intrusion barrier projects near the coast, and other factors.

3.0 HISTORICAL LAND USE
This section provides a summary of historical land use associated with the Site. This section includes a review of historic directory listings, government agency files, as well as an EDR database report. A summary of findings for each source is presented below.

3.1 City Directory Listings
A City of Hercules address directory search was performed for the Project Site by EDR Inc.

EDR’s City Directory Report includes a search of available city directory data at 5-year intervals. The search returned no records of business or other land use operations at the Site back to 1975. The results of the City directory search are provided in Appendix D.

3.2 Historic Aerial Photographs
Historical Site uses can frequently be ascertained from a review of aerial photographs. Aerial photographs of the Project area and surrounding area were provided by EDR for the years 2016, 2012, 2009, 2005, 1998, 1993, 1982, 1974, 1968, 1963, 1958, 1950, 1946, and 1939, and are summarized below in Table 1. The EDR 2019 Aerial Photo Decade Package is included in Appendix E.

Table 1 – Summary of Historic Aerial Photograph Findings Photo Year Land Use description
1939 The Site and vicinity are generally undeveloped. The Site straddles Willow Road to the south and San Pablo Avenue is in place a few hundred yards to the west. The Site is open space grassy area rolling hills with an apparent depression with areas of higher order vegetation and ponding at the northeast perimeter.
1946 No change from 1939.
1950 No change from 1939.
1958 The depressional area to the northeast is now channelized across the Site with a culvert passing below the newly construction Highway 80 to the West. Highway 4 is also constructed to the North. Small buildings appear to the East and South of the Project Site at a distance of a quarter mile. No other development is apparent.
1963 No change from 1958.
1968 Few additional buildings are scattered throughout a quarter mile radius of the site. No other land use change is apparent.
1974 No major change from 1968.
1982 A major residential and commercial development appears to the South within a quarter mile and a major commercial transportation hub appears to the east. To the north within a quarter mile, a refining operation appears.
1993 Additional major residential and commercial developments appear in every direction around the Site within a quarter mile. Industrial uses to the North have expanded greatly. 1998 No major change from 1993.
2005 Commercial and industrial uses have expended in the North and residential and commercial uses have expended in the North, South, and West.
2009 Large paved transportation use has appeared immediately to the East of the site. 2012 No major change from 2009.

2016 No change from 2009.

A review of the available historic aerial maps indicates that the Site has remained undeveloped since 1939. The Site vicinity has transformed dramatically from undeveloped minor arterial corridor, to fully developed, residential, commercial, and industrial uses along two major freeway corridors. The Site remains undeveloped with remnants of a waterway at the Northern perimeter, a tributary to Refugio Creek to the South.

3.3 Historic Topographical Maps
A historical topographic map report was prepared by EDR and included a search of a collection of public and private topographic maps. Maps dated 1902, 1914, 1916, 1947/1948, 1949/1950, 1951/1952, 1959, 1968, 1980, 2012 were provided for review by EDR and summarized below.

Table 2 summarizes the findings of the historic topo map review. The EDR 2019 Historical Topographic Map Report is included as Appendix F.

Table 2 – Summary of Historic Topographical Map Findings Photo Year Land Use description
1902 The undeveloped Site located in the middle of Refugio Valley slightly elevated on rolling hills from the valley south limit, appears to drain north to northwest and straddle an intermittent tributary of Refugio Creek to the South and lies within a depressed area at the foot of a hill to the Northeast, aligning a roadway just North of the site. RR appears along at the southern perimeter of the site.
1914 Few changes from 1902. The roadway north of the Site no longer appears and the tributary is located a few hundred feet north of the site.
1916 No change from 1914.
1947, 1948 The Site appears to drain to an independent tributary to Refugio Cree across historic San Pablo Avenue to the West.
1949,1950 Independent tributary no longer depicted within Site limits 1951,1952 No change from 1950.
1959 The tributary has been rerouted to pass through the Site through its historic intermittent path.

Highways 80 and 4 have been constructed directly to the north and west of the site. Heavy commercial/industrial development appears a mile to the north and southwest of the site. 1968 No change from 1959.
1980 Additional residential and commercial development appears to east, south north, and west of the site.
2012 Development now surrounds the Project Site in all direction up to within 1/8 mile of site.

The historic topographical maps indicate that the Project Site has been undeveloped from 1902 through 2012 as open space hillside and depressed waterway (intermittent tributary to Refugio Creek) along the norther perimeter.

3.4 Sanborn Fire Insurance Maps
Sanborn™ fire insurance maps are used to identify historic land uses that may pose a continued hazardous material risk at the Project site. These maps have been produced for most urban areas since the late 1800s as a tool to for documenting fire risk. No Sanborn maps are available for the Project Site according to the Certified Sanborn Map Report (EDR 2019) provided in Appendix G.

3.5 Government Records Search

3.5.1 File Reviews
File reviews were requested or conducted at the following government agencies to secure records not available by database or other means. File reviews were conducted at resource agencies potentially holding records of current or past land uses at facilities associated with hazardous material use or release into the environment. File reviews were conducted at the following government agencies:
 City of Hercules Planning, Building & Public Works Department (Appendix H)  City of Hercules Fire Department (Appendix I)
 Bay Area Air Quality Control District (Appendix J)
 Contra Costa County Health Services Hazardous Materials Programs (Appendix K)  San Francisco Bay Regional Water Quality Control Board—GeoTracker Database (Appendix L)
Record of permit applications, permits, releases, spills, accidents, fires, pollution complaints, etc. obtained from these file reviews is summarized below.

City of Hercules Planning, Building & Public Works Department A Public Records Request for Assessor Parcel Number 406 070 042 was submitted to the City of Hercules Planning, Building & Public Works Department on December 30, 2019 and was responded to on January 6, 2020 indicated no records were located for the site.

Contra Costa County Health Services Hazardous Materials Programs A Public Record Request was submitted to the Contra Costa County Health Services Hazardous Materials Program. Alex McMullen, Clerical Supervisor, responded on January 2, 2020 indicating that they have no records for APN 406-070-042 back to 1986 when their records began.

San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) and Department of Toxic Substances Control (DTSC)
The SFBRWQCB’s GeoTracker database is a repository of regulatory oversight files concerning undergoing investigation for pollution impacts to groundwater or threats of pollution impacts to groundwater. In addition, GeoTracker cross-tracks cleanup Site records of the DTSC.

Groundwater flow overall migrates in a westerly direction towards and into the Bay.

Thirteen current or former cleanup or permitted hazardous material sites were identified in the Geotracker map. No groundwater cleanup sites were identified within 1 mile upstream of the Project Site or within a quarter of a mile of the Site in all directions. See Figure 4 for Geotracker map.

There were also no soil cleanup sites identified within an eighth of a mile and upstream of the Project site. Two former LUST cleanup sites were identified within an eighth of a mile west (downstream) of the Project site.

The West Contra Costa Transit (T0601300532) Site located 582 feet west of the southwestern perimeter of the Project Site is a former gasoline UST cleanup Site closed on December 3, 2008.

The other LUST Site is the Caltrans Hercules Maintenance Station (T0601391848) located 554 feet to the west of the southwestern perimeter of the Project site.

The Caltrans Site was also a gasoline UST cleanup Site and has been closed since September 26, 2002. Neither Site pose a risk of hazardous materials to the Project Site due to their distance downstream both for groundwater and topographically to the Project site. Additional information for all 13 sites identified are provided in Appendix L.

3.5.2 EDR 1‐Mile Radius Database Findings
As part of the Phase I, Ground Zone obtained environmental database records through Environmental Data Resources, Inc. (EDR). The EDR’s search included both federal and state resource agencies and pollution control agency records for the Site and for facilities within a one-mile radius of the Site. All but two (HIST LUST and HIST USTs) of the databases searched were “current,” i.e., had been updated within 90 days prior to the search date.

The database search included a list of sites that generated hazardous waste or have released hazardous waste at the Site or within a ⅛, ¼, ½ and 1-mile radius of the Site. The EDR report identified at least 45 hazardous waste generators within a - mile radius of the Site. Table 3 summarizes the sites listed in the EDR report that generate hazardous waste within a ¼ mile of the Site at equal or higher elevation and up-gradient with respect to prevailing groundwater flow direction; hence sites that poses a potential risk to impact the Site. Groundwater flow direction is identified by Geosolutions Inc. in 2003 (Geosolutions 2003). The Geosolutions groundwater investigation, conducted on a site within a quarter mile downstream of the Project Site, indicated that prevailing groundwater flow is westward. None of the facilities identified in Table 3 pose a proximate risk of pollution migration to the Site since none were identified for spills leaks or onSite disposal of hazardous waste. A full record of all government database listings, sources, and coverage dates within 1 mile of the Site may be found in Appendix A (EDR Radius Report).

4.0 CURRENT LAND USE
This section provides a summary of the current land use at the Site based on tenant history, Site reconnaissance walks, and a review of the City of Hercules Development Services.

4.1 Site Reconnaissance
A Site reconnaissance survey was conducted on December 16, 2019. Table 4 summarizes the findings of that survey. In general, the Site is characterized by open space land use and freeway corridor, as the Site is sandwiched between Willow Avenue to the south, Interstate 80 to the West, Highway 4 to the North and Interstate 80 offramp from North to East. The Site is comprised of natural and artificial fill hills and a relatively natural drainage depression from East to West fed by a 6 foot by 4 foot concrete culvert at the eastern perimeter of the site, discharging to a 6 foot by 4 foot culvert at the northwestern perimeter of the Site which eventually discharges to Refugio Creek on the West side of Interstate 80. Evidence of fill from historic freeway construction and one concrete foundation from historic pile demolition. Also identified on Site are several drainage vents or wells recently installed apparently to help drain the site. An

apparent freshwater wetland associated with the drainage tributary dominates the northern ¼ of the Project area with woody canopy and wetland vegetation.

The photographs taken at the Site are presented in Appendix M.

4.2 Environmental Questionnaire
On January 14, 2020, Ground Zone with the assistance of Mr. Arvind Desai completed an environmental questionnaire to ascertain the nature of business operations and wastes generated and to assess the potential for historic or future pollution impacts to the Site (Appendix N).

According to the survey, there is no evidence of historic or current underground storage tank use on the property nor have there been any release of hazardous waste to the environment. The survey revealed no evidence of land use or business operations of any kind in over one hundred

years. The Site has not been subject to permits, citations, emergencies, dumping, waste disposal, construction, or any type of environmental hazard throughout its history.

5.0 FINDINGS and DISCUSSION
Historic land use and historic operations at the Site is comprised entirely of open space and drainage swale.

No history use of hazardous waste or disposal at the Site appears in the record.

Naturally occurring asbestos may be present at the Site in artificial fill soils due to the prevalence of serpentine in the Bay Area in general.

Aerially deposited lead at hazardous levels along Interstate 80 offramp and Willow Avenue is a certain risk. Any movement and/or reuse of soil along the perimeters of the Project Site should be preceded with lead screening.

The record collected for this assessment reveals no evidence of current operations or practices which pose an imminent threat of pollution release to the Site. The record also does not reveal evidence of any history of releases of hazardous materials or hazardous waste to the Site. The record indicates that current open space land use in compliance with federal, state and local regulatory requirements.

The record also does not contain evidence of historic hazardous material impacts from contiguous properties. According to the record, properties within a quarter mile of the Site with historic hazardous material releases at equal or higher elevation to the Site are permitted hazardous waste generators with no history of releases or cleanups. Nothing in the record indicates the existence of any ongoing potential for impacts to the Site from nearby facilities.

6.0 CONCLUSIONS and RECOMMENDATIONS
This Phase I Environmental Site Assessment has been performed in conformance with the scope and limitations of ASTM Practice E1527-13 and as presented in our proposal dated December 5, 2019. Any exceptions to, or deviations from, this practice are described in Section 7 of this report.

This assessment has revealed the no REC, HREC, or CREC conditions in connection with the property. Table 5 below summarizes recommended management actions based on our conclusions.

7.0 LIMITATIONS
Information for this assessment was obtained from sources listed in the reference section of this report. This information, to the extent it was relied on to form our opinion, is assumed to be correct and complete. Ground Zone is not responsible for the quality or content of information from these sources.

Any opinions and/or recommendations presented apply to Site conditions existing at the time of performance of services. We are unable to report on, or accurately predict, generally unforeseeable events which may impact the Site following performance of services, whether occurring naturally or caused by external forces. Therefore, we cannot assume responsibility for such events or their impact. We also cannot assume responsibility for changes in environmental standards, practices, or regulations.

Because this assessment was limited to regulatory file reviews, interviews and surveys, we cannot make any conclusions as to the condition of soil, groundwater, or building materials at the Site. Further investigation would be necessary to determine whether potential unreported, preregulation, or clandestine activities occurring at or near the Site have resulted in pollution impacts to soil, groundwater, or building materials at the Site.

The information and opinions rendered in this report are exclusively for use by Hercules Hotel Development LLC. Ground Zone will not distribute or publish this report without consent except as required by law or court order. The information and opinions expressed in this report are given in response to a limited assignment and should be considered and implemented only in light of that assignment. The services provided by Ground Zone in completing this Project were consistent with the standard for the profession. No other warranty, expressed or implied, is made.

Any party other than Hercules Hotel Development LLC shall not use this report without receiving prior authorization from Ground Zone. Unauthorized use of this report will relieve Ground Zone of any liability resulting from its use.

Because Hercules Hotel Development LLC is the current and historic real property owner at the Site, inquiry into the terms of and conditions of the its real property ownership or chain of title is outside the scope of this Phase I ESA investigation. Hercules Hotel Development LLC is presumed to be aware of land use conditions present in its real property title records which may evince the existence of pollution risks present at the Site.

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

Federal CERCLIS NFRAP site list

EXECUTIVE SUMMARY
TC5897647.2s EXECUTIVE SUMMARY 8
SEMS-ARCHIVE: SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

A review of the SEMS-ARCHIVE list, as provided by EDR, and dated 10/25/2019 has revealed that there is 1 SEMS-ARCHIVE site within approximately 0.5 miles of the target property.

RCRA-SQG: RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month.

A review of the RCRA-SQG list, as provided by EDR, and dated 06/24/2019 has revealed that there are 5 RCRA-SQG sites within approximately 0.25 miles of the target property.

ENVIROSTOR: The Department of Toxic Substances Control’s (DTSC’s) Site Mitigation and Brownfields Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which there may be reasons to investigate further. The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites.

A review of the ENVIROSTOR list, as provided by EDR, and dated 07/29/2019 has revealed that there are 9 ENVIROSTOR sites within approximately 1 mile of the target property.

TC5897647.2s EXECUTIVE SUMMARY 17
listings of potential dry cleaner sites that were available to EDR researchers. EDR’s review was limited to those categories of sources that might, in EDR’s opinion, include dry cleaning establishments. The categories reviewed included, but were not limited to dry cleaners, cleaners, laundry, laundromat, cleaning/laundry, wash & dry etc. This database falls within a category of information EDR classifies as "High Risk Historical Records", or HRHR. EDR’s HRHR effort presents unique and sometimes proprietary data about past sites and operations that typically create environmental concerns, but may not show up in current government records searches.

A review of the EDR Hist Cleaner list, as provided by EDR, has revealed that there is 1 EDR Hist Cleaner site within approximately 0.125 miles of the target property.

be present. Small amounts of chrysotile asbestos are common in serpentinite because chrysotile is one of the serpentine group minerals. Tremolite-actinolite asbestos (amphibole asbestos) may also occur with serpentinite, but such occurrences are less common than chrysotile asbestos.

This map should not be used to determine whether bedrock or soil on a particular parcel of land in or adjacent to areas identified as ultramafic rocks contains asbestos.

A site-specific investigation would be required to make such a determination.

Consequently, such occurrences are not shown on this map.

The small scale of this map (1:1,000,000) precludes showing detailed boundaries of ultramafic rock units and small occurrences of ultramafic rocks. It should be used only as a general guide to the presence of ultramafic rocks that may contain asbestos.

This map is derived from the Geologic Map of California (1:750,000 scale - one inch equals about 12 miles), Jennings (1977). No ultramafic rocks are shown in Solano and Madera counties on this map. However, ultramafic rocks are shown as present in these counties on available more detailed maps at scales of 1:250,000 (one inch equals about 4 miles) and larger. In addition to association with ultramafic rock and serpentinite, asbestos minerals are also known to occur in association with some faults This rock type has a greasy or waxy appearance and may be dark to light green, brown, yellow or white. In addition to serpentine minerals, small amounts of other minerals such as magnetite, chromite, talc, brucite, and tremolite-actinolite may Serpentinite -- Serpentinite is a rock consisting almost entirely of one or more serpentine minerals. Serpentinite is not identified as a separate rock unit on this map but is likely to be found within areas of ultramafic rock shown on the map. in particular geologic settings, certain non-ultramafic related metamorphic rock types, and magnesium-rich carbonate rocks such as dolomite. These asbestos occurrences are much less common and their locations less well known than for ultramafic rocks.

Asbestos -- Asbestos is the generic term for the naturally occurring fibrous (asbestiform) varieties of six silicate minerals. These minerals are: chrysotile, tremolite (when fibrous), actinolite (when fibrous), crocidolite (fibrous riebeckite), usually do not occur as fibrous crystals and are not asbestos minerals. Although the term serpentine is commonly used to refer to the rock serpentinite, it is actually the name of the group of minerals that makes up the rock serpentinite. amphibole mineral group. Asbestos also refers to an industrial product obtained by mining and processing deposits of the asbestiform minerals listed above. serpentinite in small veins, where the fibers are oriented perpendicular to the vein walls (cross-fiber veins) or parallel to the vein walls (slip-fiber veins).

Chrysotile fibers are one type of asbestos. The other serpentine minerals anthophyllite (when fibrous), and amosite (fibrous cummingonite-grunerite).

Chrysotile is the most common asbestos mineral in California and belongs to the serpentine mineral group. The remaining asbestos minerals belong to the Serpentine --The serpentine group minerals are hydrous magnesium silicate minerals, of which lizardite, antigorite and chrysotile are the most common.

Chrysotile forms crystals that are naturally fibrous. These fibers occur in

Definitions
Note--occurrences of non-ultramafic rock types, such as gabbro or diabase, may be included within some of the ultramafic rock areas shown on this map. Asbestos is much less likely to be associated with these non-ultramafic rock types.

This map may be viewed on the California Department of Conservation website at http://www.consrv.ca.gov, which includes links to other sites with asbestos information.

be an issue. In these areas, consideration of the implications of the presence or absence of asbestos through examination of more detailed maps and site-specific investigations could be warranted as part of public or private decision making.

This map shows the areas more likely to contain natural occurrences of asbestos in California. Its purpose is to inform government agencies, private industry and the public of the areas in the State where natural occurrences of asbestos may

MAP PURPOSE
Natural occurrences of asbestos are more likely to be encountered in, and immediately adjacent to, areas of ultramafic rocks. The general location of these rocks is noted on this map. While geologic conditions are more likely for asbestos formation in or near these areas, its presence is not certain. The only way to establish the presence or absence of asbestos at a specific location is through a detailed site examination by a qualified geologist.

EXPLANATION TEXT FOR MAP
A General Location Guide for Ultramafic Rocks in California – Areas More Likely to Contain Naturally Occurring Asbestos

MAP PURPOSE
This map shows the areas more likely to contain natural occurrences of asbestos in California. Its purpose is to inform government agencies, private industry and the public of the areas in the State where natural occurrences of asbestos may be an issue. In these areas, consideration of the implications of the presence or absence of asbestos through examination of more detailed maps and sitespecific investigations could be warranted as part of public or private decision making. Natural occurrences of asbestos are more likely to be encountered in, and immediately adjacent to, areas of ultramafic rocks. The general location of these rocks is noted on this map. While geologic conditions are more likely for asbestos formation in or near these areas, its presence is not certain. The only way to establish the presence or absence of asbestos at a specific location is through a detailed site examination by a qualified geologist.

EXPLANATION OF ULTRAMAFIC ROCK UNIT
Ultramafic rocks are dunite, peridotite, pyroxenite, and less common in California, hornblendite (IUGS classification of ultramafic rocks, in Philpotts, 1990*). These igneous rocks contain 90 percent or more of the dark colored iron-magnesiumsilicate minerals olivine, augite, hypersthene, or less commonly hornblende.

Ultramafic rocks form in high temperature environments well below the surface of the earth. By the time they are exposed at the surface by uplift and erosion, ultramafic rocks may be partially to completely altered to serpentinite, a type of metamorphic rock. Sometimes the metamorphic conditions are right for the formation of chrysotile asbestos or tremolite-actinolite asbestos in bodies of ultramafic rock or along their boundaries. Note--occurrences of non-ultramafic rock types, such as gabbro or diabase, may be included within some of the ultramafic rock areas shown on this map. Asbestos is much less likely to be associated with these non-ultramafic rock types.

INFORMATION SOURCES
The ultramafic rock areas shown on this map are adapted from Jennings, C.W., 1977, Geologic Map of California, California Department of Conservation, Division of Mines and Geology, Geologic Data Map No. 2, scale 1:750,000. *Philpotts, A.R., 1990, Principles of igneous and metamorphic petrology, Figure 6-3, IUGS (International Union of Geological Sciences) classification of ultramafic rocks: Prentice Hall, Englewood Cliffs, New Jersey, page 96.

This map may be viewed on the California Department of Conservation website at http://www.consrv.ca.gov, which includes links to other sites with asbestos information.

MAP USAGE AND LIMITATIONS
The small scale of this map (1:1,000,000) precludes showing detailed boundaries of ultramafic rock units and small occurrences of ultramafic rocks. It should be used only as a general guide to the presence of ultramafic rocks that may contain asbestos. This map is derived from the Geologic Map of California (1:750,000 scale - one inch equals about 12 miles), Jennings (1977). No ultramafic rocks are shown in Solano and Madera counties on this map. However, ultramafic rocks are shown as present in these counties on available more detailed maps at scales of 1:250,000 (one inch equals about 4 miles) and larger. In addition to association with ultramafic rock and serpentinite, asbestos minerals are also known to occur in association with some faults in particular geologic settings, certain non-ultramafic related metamorphic rock types, and magnesium-rich carbonate rocks such as dolomite. These asbestos occurrences are much less common and their locations less well known than for ultramafic rocks.

Consequently, such occurrences are not shown on this map.

This map should not be used to determine whether bedrock or soil on a particular parcel of land in or adjacent to areas identified as ultramafic rocks contains asbestos. A site-specific investigation would be required to make such a determination.

Definitions
Asbestos -- Asbestos is the generic term for the naturally occurring fibrous (asbestiform) varieties of six silicate minerals. These minerals are: chrysotile, tremolite (when fibrous), actinolite (when fibrous), crocidolite (fibrous riebeckite), anthophyllite (when fibrous), and amosite (fibrous cummingonite-grunerite).

Chrysotile is the most common asbestos mineral in California and belongs to the serpentine mineral group. The remaining asbestos minerals belong to the amphibole mineral group. Asbestos also refers to an industrial product obtained by mining and processing deposits of the asbestiform minerals listed above.

Serpentine --The serpentine group minerals are hydrous magnesium silicate minerals, of which lizardite, antigorite and chrysotile are the most common.

Chrysotile forms crystals that are naturally fibrous. These fibers occur in serpentinite in small veins, where the fibers are oriented perpendicular to the vein walls (cross-fiber veins) or parallel to the vein walls (slip-fiber veins).

Chrysotile fibers are one type of asbestos. The other serpentine minerals usually do not occur as fibrous crystals and are not asbestos minerals. Although the term serpentine is commonly used to refer to the rock serpentinite, it is actually the name of the group of minerals that makes up the rock serpentinite.

Serpentinite -- Serpentinite is a rock consisting almost entirely of one or more serpentine minerals. Serpentinite is not identified as a separate rock unit on this map but is likely to be found within areas of ultramafic rock shown on the map.

This rock type has a greasy or waxy appearance and may be dark to light green, brown, yellow or white. In addition to serpentine minerals, small amounts of other minerals such as magnetite, chromite, talc, brucite, and tremolite-actinolite maybe present. Small amounts of chrysotile asbestos are common in serpentinite because chrysotile is one of the serpentine group minerals.

Tremolite-actinolite asbestos (amphibole asbestos) may also occur with serpentinite, but such occurrences are less common than chrysotile asbestos.

DISCLAIMER
The State of California and the California Department of Conservation, Division of Mines and Geology make no representations or warranties as to the actual presence or absence of natural asbestos at specific sites within or near the ultramafic rock areas shown on this map. Further, the State and the Department make no representations or warranties regarding the accuracy of the data shown on the map. Neither the State nor the Department shall be liable under any circumstances for any direct, indirect, special, incidental or consequential damages with respect to any claim by any user or any third party on account of or arising from the use of this map.

VIEWING AND PRINTING TIPS
A General Location Guide for Ultramafic Rocks in California – Areas More Likely to Contain Naturally Occurring Asbestos Viewing the map
This map opens up in Acrobat Reader in “fit window” view. When you wish to zoom in and look at areas at a higher magnification, there are several ways to do so:

1. Use the magnifying glass icon on the left-hand tool bar and zoom in at preset increments, or

2. Click on the View pull-down menu for a variety of zoom options, or

3. Use the pop-up menu on the lower left toolbar to set exact zoom parameters.

4. To zoom back out with the magnifying glass icon active, press ctrl/alt/spacebar and click the mouse, or

5. Go back to View pull-down menu and change view, or

6. Use pop-up menu on the lower left toolbar to change view.

Printing the map
If you try to print this map, you’ll find that Acrobat Reader will simply print the entire map at your printer’s default page size. The resulting print isn’t very useful if you can only print to an 8.5 x 11 inch page. To print portions of this map at 1:1,100,000 (the original scale of the map) you’ll need Acrobat Reader and a graphics program such as Microsoft Paint, Paint Shop Pro, Corel Draw or Mac Paint. Armed with these tools, do the following:

1. Use Adobe Acrobat Reader to open map file.

2. To select an area, open the document and zoom to 100% at the area of interest. Hold mouse button down (if you have three buttons on your mouse, click on the left one) on the Text Select tool button, which will expand to three buttons. Choose the “grab graphics” tool button (last one on the right). Using this tool, select your area of interest..

3. Click on the Edit pull-down menu and select Copy. This places a copy of the selected area onto your computer’s clipboard. At this point, you can close Adobe Acrobat if your paint program requires the memory to run. If not, you can leave it open.

4. Open your paint program. In Microsoft Paint, make sure that the image area is at least as wide or as tall as the map area that you’ve selected. Choose the Edit pull-down menu, and click on Paste. In Paint Shop Pro, select Paste as New Image. The selected map area will be pasted into the view and can be printed. This “bitmap” image may appear “pixilated” or have jagged edges.

To print the entire map at full-scale requires a large-format color plotter. If you don’t have one, many reproduction firms do, and can plot the file for you.

Good Morning:

We have no records for APN 406-070-042 @ Bayberry Ave, Hercules.

Our records go back to 1986, anything prior to this would be the jurisdiction of the local fire department.

FYI: CalEPA has a new website that combines data about environmentally regulated sites and facilities in California into a single, searchable database and interactive map. By combining data from a variety of state and federal databases, the portal provides an overview of regulated activities across the spectrum of environmental programs for any given location in California.
