PROJECT GHG ANALYSIS
City of Ontario Community Climate Action Plan
The City of Ontario adopted the Community Climate Action Plan (CCAP) on December 16, 2014. The CAP contains further guidance on the City of Ontario’s GHG Inventory reduction goals, policies, guidelines, and implementation programs. The purpose of the CAP is to provide guidance on how to analyze GHG emissions and determine significance during the CEQA review of proposed development projects within the City of Ontario (1). The CAP builds upon the Reduction Plan to address City-specific information and City-specific GHG reduction measures. To address the state’s requirement to reduce GHG emissions, the City prepared its CAP with the goal of reducing GHG emissions within the City by 15% below 2008 levels by the year 2020. The City’s target is consistent with the AB 32 target and ensures that the City of Ontario achieves GHG reductions locally that complement and are consistent with state efforts to reduce GHG emissions.

As part of the CAP, the City of Ontario published a guidance document titled “Greenhouse Gas Emissions, CEQA Thresholds and Screening Tables” (December 2014). As part of this guidance, the City determined that if GHG emissions of a given project exceeds 3,000 MTCO2e/yr, then project emissions would need to be reduced by 25 percent when compared to year 2008 emissions levels.

Alternatively, the project would need to achieve a minimum of 100 points pursuant to measures identified in the Screening Tables.

The Ontario Plan (TOP) 2050 includes an update to the City’s Community Climate Action Plan (CCAP Update) which was adopted in 2014. The CCAP Update is a plan to reduce greenhouse gas (GHG) emissions and improve community resilience to hazardous conditions associated with climate change. The update to the CCAP includes updated emissions inventories; updated emissions forecasts; identifies GHG emissions reduction targets to achieve the GHG reduction goals of the City of Ontario consistent with Senate Bill 32, Executive Order S-03-05, and substantial progress toward the State’s carbon neutrality goals of Executive Order B-55-18; and measures, that when quantified, achieve the GHG reduction targets for the City. As noted in The Ontario Plan 2050 Final Supplemental Environmental Impact Report (SCH No. 2021070364) certified by the City in 2022 (TOP 2050 SEIR), the measures included in the 2022 CCAP Update are not substantially different than that of the 2014 CCAP and therefore there is no change in the environmental impacts associated with the CCAP.

GHG IMPACTS
Standards of Significance
According to the CEQA Guidelines Appendix G thresholds, to determine whether impacts from GHG emissions are significant. Would the project:
• Threshold 1: Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment?
• Threshold 2: Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of GHGs?
The evaluation of an impact under CEQA requires measuring data from a project against both existing conditions and a “threshold of significance.” For establishing significance thresholds, the Office of 2812

Planning and Research’s amendments to the CEQA Guidelines Section 15064.7(c) state “[w]hen adopting thresholds of significance, a lead agency may consider thresholds of significance previously adopted or recommended by other public agencies, or recommended by experts, provided the decision of the lead agency to adopt such thresholds is supported by substantial evidence.” CEQA Guidelines Section 15064.4(a) further states, “. . . A lead agency shall have discretion to determine, in the context of a particular project, whether to: (1) Use a model or methodology to quantify greenhouse gas emissions resulting from a project, and which model or methodology to use . . .; or (2) Rely on a qualitative analysis or performance-based standards.” CEQA Guidelines Section 15064.4 provides that a lead agency should consider the following factors, among others, in assessing the significance of impacts from greenhouse gas emissions:
• Consideration #1: The extent to which the project may increase or reduce greenhouse gas emissions as compared to the existing environmental setting. • Consideration #2: Whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project.
• Consideration #3: The extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of greenhouse gas emissions. Such regulations or requirements must be adopted by the relevant public agency through a public review process and must reduce or mitigate the project’s incremental contribution of greenhouse gas emissions. In determining the significance of impacts, the lead agency may consider a project’s consistency with the State’s long-term climate goals or strategies, provided that substantial evidence supports the agency’s analysis of how those goals or strategies address the project’s incremental contribution to climate change and its conclusion that the project’s incremental contribution is not cumulatively considerable.

As noted above, the update to the CCAP includes updated emissions inventories; updated emissions forecasts; identifies GHG emissions reduction targets to achieve the GHG reduction goals of the City of Ontario consistent with Senate Bill 32, Executive Order S-03-05, and substantial progress toward the State’s carbon neutrality goals of Executive Order B-55-18; and measures, that when quantified, achieve the GHG reduction targets for the City. As noted in the TOP EIR, the measures included in the 2022 update to the CCAP are not substantially different than that of the 2014 CCAP. Because the 2022 Update to the CCAP addresses GHG emissions reductions and is consistent with the requirements of AB 32, SB 32, and international efforts to reduce GHG emissions, Projects that comply with the CCAP Update would have a less than significant GHG impact.

PROJECT GHG EMISSIONS
The estimated GHG emissions for the Project are summarized in Table 1. The estimated GHG emissions include emissions from Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), and Refrigerants (R). As shown on Table 1, the Project would generate a total of approximately 2,238.00 MTCO2e/yr.

GHG IMPACT ANALYSIS
Would the Project have the potential to generate direct or indirect GHG emissions that would result in a significant impact on the environment?
Would the Project have the potential to conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of GHGs? The purpose of the 2022 CCAP Update is to provide guidance on how to analyze GHG emissions and determine significance during the CEQA review of proposed development projects within the City.

Because the 2022 CCAP Update addresses GHG emissions reductions and is consistent with the requirements of AB 32, SB 32, and international efforts to reduce GHG emissions, compliance with the CAP Update fulfills the description of mitigation found in the State CEQA Guidelines.

The Project will implement Screening Table Measures providing for the required points pursuant to the City Screening Tables. As such, the Project would be consistent with the GHG Development Review Process’ requirement to achieve the requisite number of points and thus the Project is considered to have a less than significant individual and cumulatively considerable impact on GHG emissions.

LEVEL OF SIGNIFICANCE BEFORE MITIGATION
Potentially Significant.

MM GHG-1
Project development proposals shall implement Screening Table Measures that achieve the requisite points per the City’s Community Climate Action Plan (CCAP) Screening Tables. The City shall verify that Screening Table Measures achieving the requisite points are incorporated in development plans prior to the issuance of building permit(s) and/or site plans (as applicable). The City shall verify implementation of the selected Screening Table Measures prior to the issuance of Certificate(s) of Occupancy. At the discretion of the City, measures that provide GHG reductions equivalent to GHG emissions reductions achieved via the Screening Table Measures may be implemented. 2814

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 19.8 annual days of extreme heat Extreme Precipitation 3.10 annual days with precipitation above 20 mm 2859
15662 - Esperanza Specific Plan Amendment (Proposed) Detailed Report, 3/13/2025 43 / 49
Sea Level Rise — meters of inundation depth
Wildfire 6.78 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

EXECUTIVE SUMMARY
SCS Engineers (SCS) was retained by GDC Investments to prepare a Phase I Environmental Site Assessment (Phase I ESA) of a 10.02-acre site located at the northeast corner of Amherst Avenue and Eucalyptus Avenue, Ontario, California (the “Subject Property” or “Property”). This assessment was performed in conformance with 40 CFR 312, Standards for Conducting All Appropriate Inquiries, and in general conformance with ASTM E1527-21.

The Property is located on the northeastern side of Amherst Avenue, immediately north of the intersection with Eucalyptus Avenue. According to tax assessor information reviewed, it is 10.02 acres and is currently undeveloped, vacant land.

Based on the historical records reviewed, SCS identified no historical structures on the Property. It was undeveloped or agricultural land from at least 1902 through 2012. A row of trees functioning as a windbreak (likely eucalyptus trees) extended north-south across the eastern portion of the Property. Around 2016, grading activities were first visible on the eastern portion of the Property, associated with activities on the adjoining site to the east. Following 2016, much more extensive grading occurred and in 2020, hundreds of soil stockpiles were visible on the central and northern portions of the Property. The appearance of the stockpile coincided with the grading and paving of the adjoining streets and SCS considers it likely that the soil was from sites with similar history (undeveloped and/or agricultural land). Further grading occurred in 2021, which likely resulted in the export or blending of that that stockpiled soil. Since 2021, the Property has remained vacant and undeveloped, with relative low points at the northwestern and southeastern corners.

The Property was vacant and undeveloped at the time of the site inspection. A chain-link fence surrounds the Property with gate access in the northeastern corner. The Property is covered in low, grassy vegetation and bare soil, with small amounts of wind-blown trash observed on the outer edges of the Property (against the fence). A depression likely due to former grading activities was observed in the northwestern portion of the Property. Rumble grates were also noted in the northeastern corner. A sloped area was observed on the southeastern boundary of the Property. A storm drain was noted in the southwestern corner of the Property.

Regulatory database information identified no known and suspected contamination sites in the area surrounding the Property. Based on a review of the available information, it is unlikely that any of these sites has negatively affected the environmental condition of the Property.

Conclusions
In summary, SCS performed a Phase I ESA of a 10.02-acre site located at the northeast corner of Amherst Avenue and Eucalyptus Avenue, Ontario, California, in conformance with the scope and limitations of 40 CFR 312 and ASTM E1527-21. Any exceptions or deviations are described in Section 8 of this report.

In the opinion of the Environmental Professional, this assessment has revealed no recognized environmental conditions, controlled recognized environmental conditions, or significant data gaps in connection with the Property. Further investigation is not recommended. 2870
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 1 1 INTRODUCTION
SCS Engineers (SCS) was retained by GDC Investments (the “User”) to prepare a Phase I Environmental Site Assessment (Phase I ESA) of a 10.02-acre site located at the northeast corner of Amherst Avenue and Eucalyptus Avenue, Ontario, California (the “Subject Property” or “Property”). A location map for the Property is presented as Figure 1 in Appendix A. This assessment was performed in conformance with 40 CFR 312, Standards for Conducting All Appropriate Inquiries (AAI), and in general conformance with ASTM International (ASTM) E1527-21.

PURPOSE
This Phase I ESA is intended to constitute appropriate inquiry into the previous ownership and uses of the Property, as required to support the assertion of the innocent landowner, contiguous property owner, and/or bona fide prospective purchaser defenses to liability (collectively, the landowner liability protections, or LLPs) under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA, a.k.a. Superfund), as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA), and the Small Business Liability Relief and Brownfields Revitalization Act of 2002.

The purpose of this investigation was to identify conditions indicative of the presence of hazardous substances as defined in CERCLA Section 101, and petroleum products, in, on, or at the Subject Property due to a release, likely release, or material threat of a future release to the environment.

If known or suspected contamination is identified, a User seeking to maintain LLPs has responsibilities in addition to completion of an AAI-compliant Phase I ESA. These “continuing obligations” include taking “appropriate care” and “reasonable steps” with respect to known or suspected releases of hazardous substances or petroleum products during the term of property ownership. In addition to these requirements under federal law, there are different requirements under state law with respect to liability protections. If warranted, SCS can provide support for clients with continuing obligations, as appropriate.

SCOPE OF SERVICES
This Phase I ESA is based on:
• Interviews with past and/or present owners, operators, and/or occupants of the Property. • Reviews of federal, tribal, state, and local government records. • Visual inspection of the Subject Property and adjoining sites performed on February 27, 2025.
• Review of historical Property use information (topographic maps, aerial photographs, fire insurance maps, previous environmental reports, etc.).
• Commonly known or reasonably ascertainable information about the Property (e.g., interviews with appropriate regulatory agency personnel, review of readily available agency files and documents, interviews with other knowledgeable persons, etc.). • Degree of obviousness of the presence or likely presence of releases or threatened releases of hazardous substances or petroleum products at the Subject Property and the ability to detect releases or threatened releases by appropriate investigation. • Information provided as a result of the additional inquiries conducted by the User. 2871
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 2 • Review of environmental liens, if provided or authorized to obtain by the User.

SPECIAL TERMS AND CONDITIONS
This Phase I ESA for the 10.02-acre site at the northeast corner of Amherst Avenue and Eucalyptus Avenue, located in Ontario, California, has been prepared specifically for GDC Investments. The report has been prepared in accordance with the care and skill generally exercised by reputable professionals, under similar circumstances, in this or similar localities. No other warranty, express or implied, is made as to the professional opinions presented herein.

No other party, known or unknown to SCS, is intended as a beneficiary of this report. Third parties use this report at their own risk. SCS assumes no liability of any kind with respect to such use. Third party reliance letters may be issued on request to SCS subject to approval of GDC Investments and payment to SCS of a fee for such letters.

LIMITATIONS AND ASSUMPTIONS
The assessment focuses on releases and threatened releases of hazardous substances or petroleum products that could be considered a recognized environmental condition (REC) and/or a liability due to their possible presence in significant concentrations (e.g., above acceptable limits set by applicable regulatory authorities) or due to the potential for contaminant migration through exposure pathways (e.g., soil vapor migration or groundwater ingestion). Materials that may contain substances not currently deemed hazardous by the U.S. Environmental Protection Agency (U.S. EPA) or the California Environmental Protection Agency (CalEPA) were not considered as part of this study.

Unless specifically included in our scope of services, formal surveys for asbestos-containing materials (ACMs), lead-based paint (LBP), water supply plumbing, mold, indoor air quality, and similar matters are not part of this assessment. SCS did not evaluate the Subject Property for compliance with land use, zoning, wetlands, or similar laws. This report is not intended to be an environmental compliance audit.

Hazardous substances naturally occurring in plants, soils, and rocks (e.g., heavy metals, naturally occurring asbestos, radon, etc.) are not typically considered in a Phase I ESA. Similarly, construction debris (e.g., discarded concrete, asphalt, etc.) is not considered a concern unless observations suggest that hazardous substances are likely to be present in significant concentrations.

Unless otherwise noted, sampling and laboratory analyses of soil, water, air, building materials, or other media, were not performed as part of this investigation. Positive identification of hazardous substances can only be accomplished through sampling and appropriate laboratory analysis.

SCS assumes no responsibility for the accuracy of information obtained from, compiled by, or provided by third-party sources, including regulatory agency listings. SCS assumes that information collected during this Phase I ESA is accurate and correct, unless SCS determines that reliable information exists to the contrary or the information is obviously inaccurate. Additional information subsequently provided, discovered, or produced may alter findings or conclusions made in this Phase I ESA report. Unless warranted, information collected has not been independently validated as part of this assessment. SCS is not responsible for consequences or conditions arising from facts that were not fully disclosed to SCS during the assessment. 2872

GENERAL SUBJECT PROPERTY DESCRIPTION
According to tax assessor information reviewed, the Property is 10.02 acres. It is currently undeveloped, vacant land.

ADJOINING SITE USE
• Northwest – Chatham Street immediately adjoins the Property to the northwest. Vacant lots are located across the street to the northwest.
• Northeast – Clifton Avenue immediately adjoins the Property to the northeast. Newly constructed townhomes and private roads are located across the street to the northeast. • Southeast – Eucalyptus Avenue immediately adjoins the Property to the southeast.

Multiple residential homes are located across the street to the southeast. • Southwest – South Amherst Avenue immediately adjoins the Property to the southwest.

Multiple residential homes are located across the street to the southwest.

PHYSICAL SETTING
Physiographic Setting
According to the U.S. Geological Survey (USGS), Corona North, California 7.5-minute topographic maps (Appendix C), the Property is located in the eastern portion of San Bernardino County at an 2873
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 4 elevation of 713 feet above mean sea level. Site topography is generally flat with a slight regional slope to the south.

Geologic Characteristics
The Property is located within the Chino Basin, which is underlain by Pleistocene and Recent Age alluvial and terrace deposits. Younger alluvium varies in thickness from a few feet at the northern portion of the basin to more than 100 feet in the southern portion. Older alluvium can be more than 1,100 feet in thickness, and averages 500 feet in thickness across the basin.

Hydrogeologic Characteristics
According to Bulletin 118 - California’s Groundwater of the California Department of Water Resources (CDWR), the Upper Santa Ana Valley Subbasin underlies the City of Ontario and is bounded by the Rialto-Colton Fault to the east. The Santa Ana Valley Subbasin sediment units include Holocene and Upper Pleistocene alluvium. According to information reviewed on the State Water Resource Control Board (SWRCB) GeoTracker website for a the Exelsior Farms leaking underground storage tank (LUST) case located at 7401 Hamner Avenue (approximately 3,000 feet southeast of the Property), in 2003, first groundwater was reported to be approximately 25 feet below ground surface (bgs) and flow direction was reported to be to the west. Based on its proximity and comparable elevation, first groundwater is likely at a similar depth beneath the Property.

Groundwater flow direction likely follows the regional surface topography to the south, potentially with a westerly component.

SUBJECT PROPERTY HISTORICAL USE SUMMARY
Based on the historical records reviewed, SCS identified no historical structures on the Property. It was undeveloped or agricultural land from at least 1902 through 2012. A row of trees functioning as a windbreak (likely eucalyptus trees) extended north-south across the eastern portion of the Property. Around 2016, grading activities were first visible on the eastern portion of the Property, associated with activities on the adjoining site to the east. Following 2016, much more extensive grading occurred and in 2020, hundreds of soil stockpiles were visible on the central and northern portions of the Property. The appearance of the stockpile coincided with the grading and paving of the adjoining streets and SCS considers it likely that the soil was from sites with similar history (undeveloped and/or agricultural land). Further grading occurred in 2021, which likely resulted in the export or blending of that that stockpiled soil. Since 2021, the Property has remained vacant and undeveloped, with relative low points at the northwestern and southeastern corners. 2879
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 10 The existence of past agricultural activities on the Property and in adjacent areas indicates a potential for pesticide and/or heavy metal (associated with dusting powders) contamination. In SCS’s experience, it is not uncommon to find trace levels of pesticides in soils at former agricultural areas in Southern California. However, these trace concentrations are rarely cause for environmental concern. Additionally, Department of Toxic Substances Control (DTSC) has issued an Interim Guidance for Sampling Agricultural Properties (DTSC, August 7, 2008) which states that the guidance “does not apply to disturbed land, such as, land that has been graded in preparation for construction, areas where imported soil has been brought in, or any other activity that would redistribute or impact the soil, other than normal agricultural practices, such as disking and plowing.” It is our opinion that, given the extensive grading that has occurred at the Property and without specific evidence of bulk pesticide storage or mismanagement on the Property, past use for agricultural purposes does not represent a significant environmental concern and collection and analysis of soil samples for pesticides is unwarranted.

HISTORICAL USE OF ADJOINING SITES
The adjoining sites were undeveloped from at least 1902 to 1931. Between the 1930s and early 2000s, they were primarily used for agriculture. Around 1973, a dairy farm was established on the adjoining site to the northwest, and a structure was observed on the adjoining site to the southwest.

The sites continued as agricultural land until at least 2016, when the adjoining sites to the southwest, northeast, and southeast appeared to be graded. The dairy farm remained operational on the northwest site until approximately 2022. In 2023, new residential homes were built on the adjoining sites to the southwest and southeast, followed by additional residential construction on the northwest and northeast sites in 2024.

PREVIOUS ENVIRONMENTAL REPORTS
The User provided the following two previous environmental reports to SCS:
• David J. Tanner & Associates, Inc., January 9, 2003. Phase I Environmental Site Assessment, Assesors Parcel No's 0128-252-03, 05, 05, 0128-332-01, 02, 03 & 04, City of Ontario, California.
• LGC Geo-Environmental, Inc., August 26, 2014. Updated Methane Site Assessment for the Proposed "Esperanza West" Residential Development, Located at the Northeast Corner of Cleveland Avenue and Bellgrave Avenue, APN's 0218-332-11 and 0218-252-17, City of Ontario, San Bernardino County, California.

The Tanner & Associates 2003 Phase I ESA was prepared for Forecast PPI and covered a much larger land area (139 acres) extending from Mill Creek Avenue to the west to Hamner Avenue to the east, and from Bellegrave Avenue to the south to what is now Chatham Avenue to the north. Tanner & Associated identified multiple residences (with suspected lead-based paint and asbestos), diesel fuel tanks, diesel pumps, a few 55-gallon drums, diesel farm equipment, animal carcasses, unauthorized dumping (primarily south of Eucalyptus Avenue), etc. None of these features appears to have been related to the Subject Property of the current Phase I ESA. The report concluded that there was no obvious evidence of a REC.

The Methane report included coverage of the Property, but identified only areas to the south of Eucalyptus Avenue as areas associated with historical Dairy operations that might have potential 2880
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 11 methane gas. SCS concurs with this conclusion. SCS identified no evidence that the Property was historically used for dairy operations.

REGULATORY AGENCY RECORDS
Local regulatory agencies and other sources were reviewed in an effort to identify any known or suspected contamination sites or incidents of hazardous waste storage or disposal, which might have resulted in soil and/or groundwater contamination, or volatile organic compound (VOC) vapor migration to the Subject Property. Generally, this includes records for the Property and adjacent parcels, although relevant information for other sites of possible interest in the area (up to one mile) may also be included. Within the City of Ontario, the San Bernardino County Fire Department (SBCFD) generally acts as the lead enforcement agency for UST compliance. If a tank has leaked and groundwater contamination is suspected, the Santa Ana Regional Water Quality Control Board (SARWQCB) generally becomes the lead agency in supervising contaminant characterization and cleanup.

(Appendix D).

California Department of Conservation, Geologic Energy
Management Division
Available oil and gas well maps from the California Department of Conservation, Geologic Energy Management Division (CalGEM) were reviewed to identify oil and gas wells on the Property or in the nearby area. According to the CalGEM Well Finder online database, the Property is not located within the boundaries of a delineated oil and gas field.

A map showing the location of the Property relative to nearby oil and gas wells is provided in Appendix D. One oil and gas production well was drilled approximately 0.77 miles to the southeast of the Property. It is identified as a dry, plugged well. No other oil or gas wells were identified within one mile of the Property. Based on the available information, no significant environmental impacts to the Property are anticipated from oil and gas wells.

National Pipeline Mapping System
SCS reviewed the National Pipeline Mapping System (NPMS) website for the Property and surrounding area to identify any hazardous materials pipelines. The NPMS is a geographic information system (GIS) created by the U.S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration (PHMSA), and Office of Pipeline Safety (OPS) in cooperation with other federal and state governmental agencies and the pipeline industry. The NPMS consists of geospatial data, attribute data, public contact information, and metadata pertaining to the interstate and intrastate hazardous liquid trunklines and hazardous liquid low-stress lines, as well as gas transmission pipelines, liquefied natural gas (LNG) plants, and hazardous liquid breakout tanks (tanks that receive and store liquids transported by pipeline) jurisdictional to PHMSA. The nominal accuracy of geospatial data in the NPMS is +/-500 feet. The NPMS does not contain information on interconnects, pump and compressor stations, valves, direction of flow, capacity, throughput, or operating pressure. In addition, distribution and gathering pipelines are not included in the NPMS.

The NPMS is built from data submitted by pipeline, LNG plant, and breakout tank facility operators.

Since 2002, transmission pipeline and LNG plant facility operators are required to submit mapping information to the NPMS and to update their submissions annually. Breakout tank operators are able to submit data to the NPMS on a voluntary basis.

Based on review of the NPMS website, one West Coast Terminals pipeline (Pipeline ID No.: 1825) is located along Edison Avenue that was permanently abandoned in 1957, approximately 0.33 miles to the north of the Property (Appendix D). The website does not contain any information about releases from these pipelines. Based on the available information, no negative environmental affects to the Property are anticipated from these pipelines.

DATABASE SEARCH
A database search for sites listed on various federal, state, tribal, and local databases in the area around the Property was obtained from EDR (February 25, 2025). A description of each of the databases searched is included in the report, which is attached as Appendix E. Among the databases 2882
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 13 included in the EDR report are NPL (federal, tribal, and state-equivalent), proposed and delisted NPL, CORRACTS (RCRA facilities subject to corrective actions), hazardous waste sites identified for investigation or remediation (SEMS [Superfund Enterprise Management System, formerly known as CERCLIS], State CERCLIS, VCP, Brownfields, etc.), LUST, sites with engineering controls, former CERCLIS (NFRAP), RCRA and state hazardous waste generators, ERNS, SWLF, USTs, and Toxic Pits.

Review of these records satisfies all requirements as set forth in 40 CFR Section 312.26 (b) and (c) with regard to the review of federal, tribal, and state government records of databases of such government records and local government records and databases of such records pertaining to both the Property and the nearby or adjoining properties. Further, the search distances for each particular database are as specified in 40 CFR 312.26 and ASTM E1527-21.

Any known or suspected contaminated sites included on these lists within 0.25 miles of the Property are discussed in the following text. As a general rule, sites beyond 0.25 miles are not anticipated to impact a site significantly. Any sites beyond 0.25 miles with a high potential to impact the Property are also discussed. Please note: the distances and directions listed in this report have been field verified and might not always match those in the EDR report.

Sites such as TSD facilities, hazardous waste generators, HAZNET, FINDS, SQGs, LQGs, USTs, HIST UST, RCRA violations, and TRIS facilities with toxic chemical releases (generally in accordance with permitting requirements - into the air, water, or land as reported under SARA Title III) use or store hazardous materials and thus may pose a potential problem in the event of a spill or leak. However, unless these sites also appear in an agency list of contaminated sites, there is no evidence of any problems at this time. Therefore, sites on these lists will not be discussed unless on or in close proximity to the Property.

Please refer to Appendix E for further information on these sites.

Property Listings
The Subject Property is not listed in any of the databases searched by EDR.

Adjoining Site Listings
The adjoining sites are not listed in any of the databases searched by EDR.

Other Database Sites
The EDR report provides a summary table of regulatory database sites within specified distances of the Property, including standard environmental records, additional environmental records, high risk historical records, and recovered governmental records. This summary table is provided beginning on Page 4 of the EDR report (Appendix E).

Several sites located within 0.25 miles of the Property are listed in databases associated with known releases of hazardous substances such as LUST, UST FINDER RELEASE, and ENVIROSTOR, but are located relatively cross- or downgradient, or based on case status and/or distance are not anticipated to negatively affect the environmental condition of the Property. Several sites located within 0.25 miles also appear in databases not typically associated with documented releases, such as Cortese, Hist Cortese, CERS, ENF, San Bern Co. Permit, WDS, CIWQS, PFAS, SCH, and Notify 65.

Based on a review of the database information, none of these sites are known to have any contamination at this time; therefore, none are anticipated to have negatively affected the 2883
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 14 environmental condition of the Property. None of the sites situated beyond 0.25 miles are anticipated to have impacted the Property.

Unmappable or Orphan Sites
Three unmappable sites were identified in the EDR report. Unmappable sites cannot be plotted due to inaccurate or incomplete addresses. Based on review of the provided data, including the estimated locations of the unmappable sites in relation to the Property, it appears unlikely that the unmappable sites have adversely affected the environmental condition of the Property. 7 USER PROVIDED INFORMATION
The following information is the responsibility of the User (40 CFR 312.22) and is addressed in a questionnaire provided to the User and attached to this report as Appendix F:
• Identification of environmental cleanup liens against the Subject Property. • Specialized knowledge or experience of the User.
• The relationship of the purchase price to the fair market value of the Subject Property.

A User Questionnaire was completed by Mr. David Waters and is included in Appendix F. The provided information is discussed below.

TITLE RECORDS
No title report was provided to SCS for review.

ENVIRONMENTAL LIENS OR ACTIVITY AND USE LIMITATIONS
No information regarding environmental liens or activity and use limitations was provided to SCS. No environmental liens or activity/use limitations were identified by SCS during the course of this assessment.

SPECIALIZED KNOWLEDGE OR EXPERIENCE
As described above, Mr. Waters indicated specialized knowledge of the Property in which the Property was historically a dairy farm operation, however, this appears to be a reference to its relationship with a much larger land area. Mr. Waters indicated that the dairy operations ceased sometime in the early 2000s, prior to their ownership. During their ownership the site was graded along with the surrounding land, however, no improvements other than those currently in place on the perimeter were installed. No other specialized knowledge regarding RECs or other environmental issues that could materially impact the current or future use of the Subject Property or have an impact on the current real estate transaction was noted by Mr. Waters.

VALUATION REDUCTION FOR ENVIRONMENTAL ISSUES
Mr. Waters is not aware of any environmental issues that would dimmish the Property value. No other property valuation information was provided to SCS. 8 DATA GAPS AND DEVIATIONS
Certain other limitations could affect the accuracy and completeness of this report, as follows:
2884
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 15 • Site Access Limitations – None.
• Physical Obstructions to Observations – None.
• Outstanding Information Requests – None.
• Historical Data Sources Failure – SCS attempted to review the referenced historical sources (i.e., aerial photographs, topographic maps, city directories, etc.) in a minimum of five-year increments. Breaches in the sequence of reviewed sources are due to the limitations of the referenced collections. Based on the available information, this is not considered a significant data gap.
• Other Limitations – None.

2885
Phase I ESA – 10.02-Acre Site at NE Corner of Amherst and Eucalyptus Avenues www.scsengineers.com 16 9 FINDINGS AND OPINIONS
Based on the scope of work performed, SCS finds the following:

SCS was retained by GDC Investments to prepare a Phase I ESA of a 10.02-acre site located at the northeast corner of Amherst Avenue and Eucalyptus Avenue, Ontario, California (the “Subject Property” or “Property”). This assessment was performed in conformance with 40 CFR 312, Standards for Conducting All Appropriate Inquiries, and in general conformance with ASTM E1527-

21. The Property is located on the northeastern side of Amherst Avenue, immediately north of the intersection with Eucalyptus Avenue. According to tax assessor information reviewed, it is 10.02 acres and is currently undeveloped, vacant land.

Based on the historical records reviewed, SCS identified no historical structures on the Property. It was undeveloped or agricultural land from at least 1902 through 2012. A row of trees functioning as a windbreak (likely eucalyptus trees) extended north-south across the eastern portion of the Property. Around 2016, grading activities were first visible on the eastern portion of the Property, associated with activities on the adjoining site to the east. Following 2016, much more extensive grading occurred and in 2020, hundreds of soil stockpiles were visible on the central and northern portions of the Property. The appearance of the stockpile coincided with the grading and paving of the adjoining streets and SCS considers it likely that the soil was from sites with similar history (undeveloped and/or agricultural land). Further grading occurred in 2021, which likely resulted in the export or blending of that that stockpiled soil. Since 2021, the Property has remained vacant and undeveloped, with relative low points at the northwestern and southeastern corners.

The Property was vacant and undeveloped at the time of the site inspection. A chain-link fence surrounds the Property with gate access in the northeastern corner. The Property is covered in low, grassy vegetation and bare soil, with small amounts of wind-blown trash observed on the outer edges of the Property (against the fence). A depression likely due to former grading activities was observed in the northwestern portion of the Property. Rumble grates were also noted in the northeastern corner. A sloped area was observed on the southeastern boundary of the Property. A storm drain was noted in the southwestern corner of the Property.

Regulatory database information identified no known and suspected contamination sites in the area surrounding the Property. Based on a review of the available information, it is unlikely that any of these sites has negatively affected the environmental condition of the Property. 10 CONCLUSIONS
In summary, SCS performed a Phase I ESA of the property located at the 10.02-acre site at the northeast corner of Amherst Avenue and Eucalyptus Avenue, located in Ontario, California, in conformance with the scope and limitations of 40 CFR 312 and ASTM E1527-21. Any exceptions or deviations are described in Section 8 of this report.

In the opinion of the Environmental Professional, this assessment has revealed no recognized environmental conditions, controlled recognized environmental conditions, or significant data gaps in connection with the Property. Further investigation is not recommended. 2886

EXECUTIVE SUMMARY

DESCRIPTION
Environmental Data Resources, Inc.’s (EDR) City Directory Abstract is a screening tool designed to assist environmental professionals in evaluating potential liability on a target property resulting from past activities.

EDR’s City Directory Abstract includes a search and abstract of available city directory data. For each address, the directory lists the name of the corresponding occupant at approximately five year intervals.

Business directories including city, cross reference and telephone directories were reviewed, if available, at approximately five year intervals for the years spanning 1922 through current. This report compiles information gathered in this review by geocoding the latitude and longitude of properties identified and gathering information about properties within 1320 feet of the target property.

Summary information obtained is provided in the text of this report.

RECORD SOURCES
The EDR City Directory Report accesses a variety of business directory sources, including Haines, InfoUSA, Polk,Cole, Bresser, and Stewart. Listings marked as EDR Digital Archive access Cole and InfoUSA records.

The various directory sources enhance and complement each other to provide a more thorough and accurate report.

EDR is licensed to reproduce certain City Directory works by the copyright holders of those works. The purchaser of this EDR City Directory Report may include it in report(s) delivered to a customer.

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.

3033
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.

US BROWNFIELDS: A Listing of Brownfields Sites
Brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Cleaning up and reinvesting in these properties takes development pressures off of undeveloped, open land, and both improves and protects the environment.

Assessment, Cleanup and Redevelopment Exchange System (ACRES) stores information reported by EPA Brownfields grant recipients on brownfields properties assessed or cleaned up with grant funding as well as information on Targeted Brownfields Assessments performed by EPA Regions. A listing of ACRES Brownfield sites is obtained from Cleanups in My Community. Cleanups in My Community provides information on Brownfields properties for which information is reported back to EPA, as well as areas served by Brownfields grant programs.

It contains addresses of some locations where law enforcement agencies reported they found chemicals or other items that indicated the presence of either clandestine drug laboratories or dumpsites.

In most cases, the source of the entries is not the Department, and the Department has not verified the entry and does not guarantee its accuracy. Members of the public must verify the accuracy of all entries by, for example, contacting local law enforcement and local health departments.

The list represents deed restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land use restriction at the local county recorder’s office. The land use restrictions on this list were required by the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed restriction, or a land use restriction that binds current and future owners.

EPA WATCH LIST: EPA Watch List
EPA maintains a "Watch List" to facilitate dialogue between EPA, state and local environmental agencies on enforcement matters relating to facilities with alleged violations identified as either significant or high priority. Being on the Watch List does not mean that the facility has actually violated the law only that an investigation by EPA or a state or local environmental agency has led those organizations to allege that an unproven violation has in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the alleged violations that were detected, but instead indicates cases requiring additional dialogue between EPA, state and local agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

2020 COR ACTION: 2020 Corrective Action Program List
The EPA has set ambitious goals for the RCRA Corrective Action program by creating the 2020 Corrective Action Universe. This RCRA cleanup baseline includes facilities expected to need corrective action. The 2020 universe contains a wide variety of sites. Some properties are heavily contaminated while others were contaminated but have since been cleaned up. Still others have not been fully investigated yet, and may require little or no remediation.

Inclusion in the 2020 Universe does not necessarily imply failure on the part of a facility to meet its RCRA obligations.

When Congress passed the Clean Air Act Amendments of 1990, it required EPA to publish regulations and guidance for chemical accident prevention at facilities using extremely hazardous substances. The Risk Management Program Rule (RMP Rule) was written to implement Section 112(r) of these amendments. The rule, which built upon existing industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances to develop a Risk Management Program, which includes a(n): Hazard assessment that details the potential effects of an accidental release, an accident history of the last five years, and an evaluation of worst-case and alternative accidental releases; Prevention program that includes safety precautions and maintenance, monitoring, and employee training measures; and Emergency response program that spells out emergency health care, employee training measures and procedures for informing the public and response agencies (e.g the fire department) should an accident occur.

HIST FTTS: FIFRA/TSCA Tracking System Administrative Case Listing A complete administrative case listing from the FIFRA/TSCA Tracking System (FTTS) for all ten EPA regions. The information was obtained from the National Compliance Database (NCDB).

PFAS NPDES: Clean Water Act Discharge Monitoring Information Any discharger of pollutants to waters of the United States from a point source must have a National Pollutant Discharge Elimination System (NPDES) permit. The process for obtaining limits involves the regulated entity (permittee) disclosing releases in a NPDES permit application and the permitting authority (typically the state but sometimes EPA) deciding whether to require monitoring or monitoring with limits. Caveats and Limitations:

Less than half of states have required PFAS monitoring for at least one of their permittees and fewer states have established PFAS effluent limits for permittees. New rulemakings have been initiated that may increase the number of facilities monitoring for PFAS in the future.

To date, these military specification fire-fighting foams are fluorinated and have been historically used for training and extinguishing. The 2018 FAA Reauthorization Act has a provision stating that no later than October 2021, FAA shall not require the use of fluorinated AFFF. This provision does not prohibit the use of fluorinated AFFF at Part 139 civilian airports; it only prohibits FAA from mandating its use. The Federal Aviation Administration?s document AC 150/5210-6D - Aircraft Fire Extinguishing Agents provides guidance on Aircraft Fire Extinguishing Agents, which includes Aqueous Film Forming Foam (AFFF).

EDR HIGH RISK HISTORICAL RECORDS
EDR Exclusive Records
EDR MGP: EDR Proprietary Manufactured Gas Plants
The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants) compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.
