Parcel A - Parcel A consists of two industrial parcels located to the south of the Land Parcels and separated by G Street.
• The northern parcel is located on the north side of G Street at 390 Bay Boulevard (APN 567-022- 30-00) and developed with Rohr Buildings 99 and 100. Building 99 consists of 35,560 square feet constructed in 1980. Building 99 was previously used for human resources, training, gym, and medical services by Rohr. Building 100 consists of 2,800 square feet constructed in 1980. Building 100 was previously used as a laboratory, research and development by Rohr and truck maintenance before Rohr purchased it. A small oil/water separator was previously utilized by the Rohr laboratory use with the laboratory equipment. The site is currently leased to Land Care, a landscaping company since March 2022. Land Care utilizes Building 100 to store equipment and uses the gated parking lot to store trucks/vehicles. Building 99 is currently vacant office and service space that is not used by Land Care.
• The southern parcel is located on the south side of G Street at 795 H Street (APN 571-330-35-00) and developed with Rohr Building 29. Building 29 consists of 281,597 square feet constructed between 1957 and 1962. The building interior consists of former office, tooling, laboratory, and photo lab areas, and hydraulic powered crane systems. A former crane pit is located on the north side of the building. The pit is reported to be approximately 18-inches deep and was filled with rain water. Former testing labs, hydraulic pumps, and storage areas were located on the north side of the building. The building was vacant from September 2020 until November 2021. In the summer of 2021, approximately 50,000 square feet of mezzanine was removed from the east wall of the building.

The site is currently leased to Marine Group and Proactive Logistics. Marine Group leases approximately 1,500 square feet to store motor homes on the south side of Building 29. Proactive Group Logistics leases approximately 150,000 square feet in the central portion of Building 29 for storage. The northern portion of the Building 29 is currently not in use.

In April 2023, Wohl intends to demolish the northern 24,000 square feet of Building 29 to construct a new loading dock. Once demolition is complete remedial activities including removing volatile organic compound (VOC) impacted soil and installing and operating a sub-slab depressurization system (SSDS) to mitigate VOCs in soil vapor from impacted groundwater will be completed as part of the Cleanup and Abatement Order No. R9-2021-0042 (CAO) discussed further below.

Historical Use
Land Parcels
According to available historical sources, the Land Parcels was undeveloped or vacant land in 1904. From 1928 to 1949, the Land Parcels were agriculturally developed land. From 1953 to at least 1985, the Land Parcels were developed with multiple small industrial structures. Businesses reportedly included aircraft parts manufacturing, refrigeration unit repair, storage, junkyards, and a veterinary hospital. According the city directories, former tenants on the subject property appeared to include B&H Metal Co., Hammer Benj W, Lyman Jos, Mansell Marine Inc. engine exchange, Mansell Earl A (1955-1960); South Bay Vet Hospital (1956-1966); Post Aircraft Co. Inc. (1960); Yarie Richard J GA27905, Post Aircraft Co GA (1961); A&R Used

Auto Parts wreckers, South Bay Marine boat sales & repair (1965); Ultra Plastics (1966); A&R Used Truck Parts, SD Pump & Compressor Supply (1971-1986); Thermo King (1975); Durrant Marcia A, Elliott Carol (1979-1982); Edwards Hugh L (1980-1986); and Jennings Dale J (1986). According to the July 2022 Revised Baseline Human Health Risk Assessment prepared by Haley & Aldrich (H&A), after 1953, the Land Parcels at 360, 364, and 368 Bay Boulevard were developed with mixed commercial/industrial and residential use.

Businesses that occupied these parcels included aircraft parts manufacturing, refrigeration unit repair, storage, junkyards, and a veterinary hospital. 360 Bay Boulevard was formerly used for auto maintenance and repair, auto dismantling, and salvaging that included a gold ore extraction/recovery operation. By the mid-1980s, the properties were acquired by the City of Chula Vista and business operations ceased. In 1999, Rohr acquired the Land Parcels and they have remained vacant since.

Parcel A - Buildings 99/100
According to available historical sources, Parcel A currently was developed with agriculturally developed land from 1928 to 1949. From 1953 to 1966, the site was developed with a trailer park and a parking lot.

By 1976, the trailer park was no longer present. By 1980, Buildings 99 and 100 were constructed on the property. According the city directories, former tenants on the subject property appeared to include Duvall Co. (1956-1961)Harbor Trailer Park, Maksor Trailer Park (1956-1975); Lawless Detat Diesel (1980) and Valley Det Dies All (1985). According to the H&A July 2022 Revised Baseline Human Health Risk Assessment, Valley Detroit Diesel repaired semi-truck engines at Buildings 99 and 100 starting in 1978. In 1986, Rohr purchased Buildings 99 and 100 from Valley Detroit Diesel and used the buildings primarily for administrative purposes.

Test laboratories were housed in Building 100 until 2021.

Parcel A - Building 29
According to available historical sources, Parcel A was agriculturally developed land in 1928. Several small structures were located on the northeast corner and southern portion of the parcel located south of G Street. By 1949, the parcel was developed with several structures on the central and southern (Building 28) portions of the site. By 1964, the parcel was developed with a large building (Building 29), a smaller building (Building 28) on the south side of the site, and several out-buildings on the northeast corner of the parcel as part of the Rohr facility. Building 28 was used as a cafeteria and a warehouse. By 1996, Building 28 had been removed and was replaced with a parking lot. According to the H&A July 2022 Revised Baseline Human Health Risk Assessment, Building 29 was constructed by Rohr in phases beginning in about 1957 to 1962.

Building 29 was covered under the Rohr North Campus address of 850 Lagoon Drive. The building was used for tooling and machining and office space. The Maintenance Department for the facility was located in the northern portion of the building. The building also formerly housed laboratories, kitting, an Aftermarket Spares Warehouse, Service Center and FAI repairs, storage, tool calibration, product development, and office space. Historical uses for the parcel prior to Rohr included agriculture, a possible lumber yard, and residential.

In 2020, Rohr sold the Land Parcels and Parcel A to PSIP Wohl.

Previous Site Investigations
The subject property was identified on the GeoTracker database as part of ongoing investigations associated with Rohr, Inc. and Cleanup and Abatement Order (CAO) No. R9-2021-0042. The Rohr facility has been divided into three parts: Parcels A, B, and C. Buildings 29, 99, and 100 were investigated as part of Case Number T10000011095 Goodrich Aerostructures – North Campus – Eastern Parcel A at 850 Lagoon Drive. The Land Parcels at 360, 364, and 368 Bay Boulevard were formerly investigated as Parcel C (Case Number T0608199629). Upon the sale of Parcel A and the Land Parcels to PSIP Wohl, the Land Parcels (APNs 567-022-28, 567-022-31, and 567-022-33) were added to Parcel A and included in the H&A July 2022 Revised Baseline Human Health Risk Assessment.

Partner reviewed available documents on the GeoTracker online database. Previous investigations conducted between 1986 and 2022 at the subject property have included soil, soil vapor, and groundwater sampling. Historical environmental features on Parcel A have been investigated for their specific chemicals of potential concern (COPCs) in soil, soil vapor, indoor air, and groundwater as well as indoor air screening (Building 29). The most recent information was largely provided in the April 2021 Revised Conceptual Site Model (CSM), the July 8, 2022 Revised Baseline Human Health Risk Assessment (HHRA) and the December 20, 2022 Demolition and Environmental Management Plan (DEMP) prepared for the North Campus Parcel A, Chula Vista, CA (Site ID #2092900) by Haley & Aldrich. Haley & Aldrich is the primary consultant for Rohr.

The April 2021 Revised Conceptual Site Model (CSM) report prepared by Haley & Aldrich indicated that historical environmental features that could be potential sources of chemicals beneath Parcel A included aboveground storage tanks (ASTs), underground storage tanks (USTs), paint booths, and vapor degreasers.

Figures 2, 3, and 4 in the CSM depicts the former operational features, including buildings, ASTs, USTs, underground vessels, vaults, paint booths, degreasers, hydraulic equipment, and maintenance and storage areas located at the subject property. This equipment has been removed. A summary of pertinent information is summarized below:
• Formerly Thermo King (Case Number T0608199629) – 340 Bay Blvd.

In the late 1980s, the environmental due diligence conducted by Rohr identified recognized environmental conditions (RECs) at the subject property and the adjacent property to the north. Regulatory cases were opened with the Couth of San Diego Department of Environmental Health (DEH) for subject property (350- 360 Bay Boulevard) and the adjacent properties to the north (340 and 390 Bay Boulevard and 798 Lagoon Drive), commonly referred to as Rohr IDs 4, 11, 10, 5, and 8; the Bay Boulevard Parcels; or Vacant Bay Boulevard Properties. Between 1987 and 2007, soil and groundwater investigations, some soil remediation and groundwater monitoring was conducted on the parcels under the oversight of the DEH. No Further Action (NFA) Letters were issued by DEH in 2001, 2004, 2006, and 2007.

Between 1987 and 2001, environmental investigations were conducted at the subject property (350-360 Bay Boulevard – DEH Establishment # H26520-001). The former use of the subject property included an auto repair/salvage yard (with gold ore extraction) and the storage of used appliances. The investigations included soil and groundwater samples for lead, pesticides and polychlorinated biphenyls (PCBs). Lead and Total Petroleum Hydrocarbons (TPH) was identified in soil. Trichloroethene (14 micrograms per liter (µg/l in MW-2) and Chloroform (3-5 µg/l in MW-1 to MW-3) were identified in three groundwater wells onsite and the adjacent Rohr site (located adjacent to the west, southwest, south). Concentrations were detected above the recommended California State Action Level of 5 µg/l. Groundwater impacts were thought to have originated offsite. It was not clear from the documents reviewed how long groundwater continued to be monitored. Pesticides and PCBs were detected at relatively low concentrations (below concentrations requiring action).

According to the Case Closure Summary dated September 6, 2001, the subject property was identified as a Vacant Lot (350-360 Bay Boulevard) owned by the City of Chula Vista. In February 2001, approximately 800 cubic yards lead contaminated soil were excavated to a depth of 2 feet and disposed offsite to the Otay Class I Landfill. Confirmation soil samples were collected from the perimeter and the floor of the footprint of the excavation at statistically random locations. The consultant concluded that the mean total lead concentration in-situ soils at the site was 54 milligram per kilogram (mg/kg) and the upper 95% confidence interval was 71 mg/kg, both lower than the residential (PRG) of 400 mg/kg. The consultant concluded that this soil contamination did not present a human health risk at the subject property. The proposed future use of the site was listed as light industrial with paved areas and building on concrete slabs. On September 17, 2001, DEH issued a No Further Action (NFA) letter.

In July 2016, Haley & Aldrich, Inc. prepared a Phase I ESA for the subject property and adjacent properties to the north for Rohr, the property owner. Rohr was proposing to sell the Bay Boulevard parcels. The subject property was vacant land at the time of the 2016 assessment. Haley & Aldrich, Inc. identified the RECs associated with lead, pesticides, and polychlorinated biphenyls (PCBs), in connection with the subject property and adjacent properties:

Onsite RECs
• Lead in Soil (Rohr IDs 5 and 8 -350-360 Bay Boulevard): In 2001, approximately 1,500 cubic yards of surface soil containing lead was excavated and used as foundation material for the cap at the Otay Class I Landfill. Regulatory oversight was conducted under the DEH VAP. An NFA letter was issued to the City of Chula Vista, but it was not posted on the GeoTracker website nor was it noted in the ERIS Database Report. The subject property cleanup level for lead at that time was the residential California Human Health Screening Level (CHHSL) of 150 milligrams per kilogram (mg/kg); the current residential CHHSL for lead is 80 mg/kg. • PCBs in Soil (All Rohr IDs): PCBs were detected by URS Corporation (URS) in the drainage swale along the western boundary of the subject property (URS 2015). The source of the PCBs is not known. PCBs were also present in soil on the Rohr IDs 5 and 8 parcels at concentrations up to 7.4 mg/kg. It was unclear whether PCB-containing soil on these parcels had been characterized and removed.

• Agricultural Property Use (All Rohr IDs): The subject property had a history of agricultural use for cultivating citrus and row crops prior to the 1950s. There was the potential that pesticides, both inorganic (containing metals) and organic may have been used to control pests.

In December 2016, Haley & Aldrich, Inc. prepared a Phase II investigation for the subject property to investigate the RECs identified in the June 2016 ESA. The soil analytical results were compared to the U.S.

EPA Region 9 Regional Screening Levels (RSLs) and, for lead, the California Department of Toxic Substances Control (DTSC) Human and Ecological Risk Office (HERO). Arsenic concentrations were compared to DTSC established background concentrations for Southern California of 12 milligrams per kilogram (mg/kg).

Analytical indicated the following:

Soil
• The concentrations of volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PAHs), arsenic, PCBs detected were below their respective residential RSLs. • Total Petroleum Hydrocarbons (TPH) were detected at concentrations between 3.3 J to 190 mg/kg at 795 H Street and 360, 364, 368 and 390 Bay Boulevard. • Thallium (0.156 J to 0.929 mg/kg) was detected at 364 Bay Boulevard (Rohr Property ID 9) above the residential RSL, but below the commercial/industrial RSL.

Groundwater
• VOCs detected in the groundwater were below the MCL and the vapor‐ intrusion screening levels for these compounds.
• The arsenic concentration (0.0149 mg/l and 0.0112 mg/l) was slightly above the MCL of 0.010 mg/l at 360 and 368 Bay Boulevard/Rohr Property IDs 8 and 6.

The site investigation is now part of the ongoing larger Goodrich Aerostructures – North Campus – Eastern Parcel A (Case Number T10000011095) investigation under the oversight of the RWQCB. On April 9, 2018, Haley & Aldrich and Rohr met with the RWQCB to discuss the results of the 2016 Phase II investigation and additional scope of work. The scope of work included a soil vapor survey; however, Haley & Aldrich indicated that it was eliminated from the scope since Rohr will require that any buildings constructed on the subject property by a buyer include a vapor barrier as part of the property transaction. On December 26, 2018, Haley & Aldrich, Inc. submitted a Work Plan for Additional Investigation to the RWQCB. The proposed sample locations were located on the parcels adjacent to the north of the subject property. • Goodrich Aerostructures – North Campus – Eastern Parcel A (Case Number T10000011095) – 850 Lagoon Drive
The April 2021 Revised Conceptual Site Model (CSM) report prepared by Haley & Aldrich indicated that historical environmental features that could be potential sources of chemicals beneath Parcel A included aboveground storage tanks (ASTs), underground storage tanks (USTs), paint booths, and vapor degreasers.

Figures 2, 3, and 4 in the CSM depicts the former operational features, including buildings, ASTs, USTs, underground vessels, vaults, paint booths, degreasers, hydraulic equipment, and maintenance and storage areas located at the subject property. Table 1 – Environmental Historical Features for Parcel A provides detail regarding the current status of areas or features of potential environmental concern identified in the

environmental investigations. The status of the areas or features of potential environmental concern is listed as closed, inactive, or removed. According to the Revised CSM, the environmental investigations were conducted to evaluate chemical impacts to soil, soil gas, and groundwater as well as indoor air screening (Building 29).

The results of the site investigations identified the following chemicals of potential concern (COPCs) in soil within the Project footprint: VOCs, Total Petroleum Hydrocarbons (TPH), semi-volatile organic compounds (SVOCs), PCBs and the organochlorine pesticide, DDT. Metals concentrations within the Project footprint fall within background ranges. Of the VOCs, trichloroethene (TCE) and tetrachloroethene (PCE) were the primary VOCs detected in soil in Project footprint and vicinity. The maximum concentrations of TCE and PCE were reported in boring B29-23 (37,800 µg/kg) and B29-28 (1,260 µg/kg), respectively. The maximum PCB (Aroclor 1260) concentration reported for soil in the Project footprint was 1,300 µg/kg in boring B29- 05 (sample ID B29-05-2). This sample was also reported to contain low concentrations of TPH (in the oil carbon range [C32-C44]; 185 mg/kg), certain SVOCs (maximum concentration was for fluoranthene, 0.21 mg/kg) and DDT (0.021 mg/kg). The maximum VOC soil gas concentrations reported within the vicinity of the Project footprint were: Chloroform: 39,000 µg/m3; PCE: 11,000 µg/m3; and TCE: 3,000,000 µg/m3.

In September 2020, Rohr sold Parcel A that includes Buildings 29, 99, and 100 (assessor parcel number [APN] 567-022-30 and the eastern portion of APN 571-330-29) to PSIP Wohl. Wohl had also purchased the vacant parcels (Also referred to as the Land Parcels) at 360, 364, and 368 Bay Boulevard (APNs 567-022-28, 567-022-31, and 567-022-33). These parcels, formerly included in Parcel C, were now also included in the Update to the Revised HHRA. With these added parcels, Parcel A occupied approximately 14.7 acres.

The HHRA stated that Wohl intended to raze the northern portion of Building 29 to build a loading dock and may raze Buildings 99 and 100 to redevelop this parcel and the adjoining vacant properties to the north for surface parking. The Update to the Revised HHRA considered two scenarios, one with Buildings 99 and 100 remaining in place and the other assuming these buildings have been demolished. In addition, buildings may be constructed in the future at undetermined locations on that portion of Parcel A.

Previous investigations conducted between 1986 and 2022 at the subject property have included soil, soil vapor, and groundwater sampling. Historical environmental features on Parcel A have been investigated for their specific chemicals of potential concern (COPCs) in soil, soil vapor, indoor air, and shallow groundwater.

Historical chemical sources are coincident with former Site areas associated with long-term chemical usage.

VOC releases have migrated through the soil to groundwater, resulting in a groundwater plume that extends westward below Parcel B (adjoining parcel to the west). Soil vapor has the potential to migrate through the building slab and into indoor air. Potential receptors to soil and soil vapor include an onsite commercial/industrial worker, a landscaper/utility worker, and a construction worker.

A comprehensive summary of previous investigations is provided in HHRA and covers:
• 1986-1996 Fuel underground storage tanks (USTs) closures at Buildings 99 and 100 • 1987-2001 350-360 Bay Boulevard Site Assessments related to the lead soil, PCBs, and VOCs • 1998 Adrian Brown Phase I of the Rohr facility
• 1998 and 1999 San Diego Formation Aquifer Testing
• 1999 Blanchard Grinder UST closure at Building 29
• 2013 Supplemental Remedial Investigation by URS
• 2016 Haley & Aldrich Phase I and IIs at Buildings 29, 99, and 100 and the Vacant Bay Boulevard Properties
• 2018 Sub-Slab and Focused Soil Vapor Survey at Buildings 29, 99, and 100 • 2018-2019 Indoor air screening in Building 29
• 2020 Haley & Aldrich Data Gap Assessment to further characterize the nature and extent of VOCs in soil and groundwater and conduct some step-out sampling in areas where arsenic and PCBs had been detected above screening levels during the Phase II • 2020 GSI Environmental, Inc. Phase I Screening Investigation on Parcel A • 2020 Partner Engineering and Science, Inc. Phase I for 350-368 Bay Boulevard • 2022 Haley & Aldrich Data Gap Assessment
Based on the results of the HHRA, Haley & Aldrich concluded:

Buildings 99/100 - No remediation or mitigation was necessary to protect the on-site receptors. Based on these results, Haley & Aldrich requested that the RWQCB provide concurrence that no further action was warranted and Rohr had met the requirements of the CAO for this exposure area (that includes 360, 364 and 368 Bay Boulevard).

Building 29 – No remediation or mitigation was necessary to protect the on-site landscaper.

Based on sub-slab soil vapor data for the on-site commercial/industrial worker, the cumulative incremental lifetime cancer risks (ILCR) was greater than the acceptable threshold of 1 x 10-5 and the total hazard index (HI) was greater than the acceptable total HI of 1 for the on-site commercial/industrial worker.

Bromodichloromethane, chloroform, cis-1,2-dichloroethene (cis-1,2-DCE), tetrachloroethene (PCE), and trichloroethene (TCE) were driving the risk. Heath-based remediation goal (HBRGs) were derived for these chemicals of potential concern (COPCs) in soil vapor to reduce estimated health risks for the on-site commercial/industrial worker from exposure to inhalation of indoor air for Building 29. The soil vapor HBRGs for bromodichloromethane, chloroform, cis-1,2-DCE, PCE, and TCE were 70, 80, 100, 370, and 350 micrograms per cubic meter (µg/m3). Haley & Aldrich stated that the Owner would be installing a sub-slab depressurization system (SSDS) beneath Building 29 as a vapor intrusion mitigation measure and implementing an Risk Management Plan (RMP).

For the on-site construction worker, the cumulative ILCR was less than the acceptable cumulative ILCR threshold of 1 x 10-5 and the lead exposure point concentration (EPC) was less that the commercial/ industrial California Department of Toxic Substances Control Screening Level (DTSC-SL) of 500 milligrams per kilogram (mg/kg). However, the total HI was greater than the acceptable total HI of 1. Remediation or mitigation was therefore warranted to protect the on-site construction worker. TCE was driving the risk. A HBRG was derived for TCE in soil to reduce estimated human health risks for the on-site construction worker

during excavation to construct the new loading dock on the north end of Building 29. The HBRG for TCE in this area is 1.5 mg/kg.

On December 20, 2022, Haley & Aldrich prepared a Demolition and Soil Environmental Management Plan (DEMP) for former Rohr, Inc. North Campus Parcel A on behalf of the property owner, PSIP Wohl Bay Boulevard, LLC, and Rohr. The DEMP will be implemented during the demolition of the northern 24,000 square feet of Building 29 where soil containing TCE will be excavated and disposed at a permitted facility.

It was anticipated that the DEMP would be implemented in 2023. The DEMP indicated:
• PSIP Wohl had made improvements to the building that included installing a new heating, ventilation, and air conditioning system and sealing and polishing the concrete floor. PSIP Wohl was required through the Purchase and Sale Agreement with Rohr to install a sub-slab depressurization system (SSDS) to address volatile organic compounds (VOCs) in soil gas that are present beneath the slab in Building 29. A separate Work Plan will be submitted that will describe the design, installation, and monitoring of the SSDS to address soil gas beneath the building slab.

The SSDS will be installed during building renovation and prior to a tenant occupying the building. • A Risk Management Plan (RMP) would be prepared and implemented to address potential future vapor intrusion risk to building occupants. The RMP will include:
• 1) An SSDS post-installation monitoring and performance plan to evaluate the effectiveness of the SSDS in mitigating potential vapor intrusion. Indoor air sampling which is a requirement of the CAO would be included. The plan would be implemented before a tenant occupies the building. 2) Restrictions on changes to the existing building slab; 3) A Contingency Plan; 4) A schedule for performing post-installation sub-slab and indoor air sampling and preparing SSDS performance monitoring reports, and a Post-Mitigation Completion Report; and 5) The preparation and filing of a deed restriction containing restrictions on use and occupancy of Parcel A (the Grant Deed in favor of PSIP Wohl recorded in September 2020 contains such restrictions and satisfies such deed restriction requirement).

During the vicinity reconnaissance, Partner observed the following land use on properties in the immediate vicinity of the subject property:

Immediately Surrounding Properties
Northwest: Vacant land at 350 and 340 Bay Boulevard and 798 F Street (Collins Aerospace (Rohr ID 5, 10, 4, and 11), followed by Lagoon Drive.

Northeast: Bay Boulevard, followed by Interstate 5 Freeway, railroad tracks, Sweetwater Authority (744 F Street), and Cabrillo Motor Lodge (731 G Street), Vistan Apartments (494 South Oaklawn Avenue), Blue Link Station – H Street (745 H Street), and a multi-tenant commercial building (730 H Street).

Southeast: H Street, followed by vacant land (former Rohr Inc.-South Campus at 850 Lagoon Drive).

Southwest: Stormwater ditch, railroad tracks, electrical transmission line, followed by Collins Aerospace (former Rohr Inc.- North Campus and Parcel B) at 850 Lagoon Drive.

According to groundwater sampling data at the subject property and topographic map interpretation, the depth to groundwater in the vicinity of the subject property is inferred to be approximately 20 to 35 feet below ground surface (bgs) and flows to the west (Haley & Aldrich, Inc., January 11, 2018).

Findings and Opinions
Recognized Environmental Condition
A recognized environmental condition (REC) refers to the presence of hazardous substances or petroleum products in, on, or at the subject property due to a release to the environment; 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 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 following was identified during the course of this assessment:
• The subject property and adjacent properties are part of the ongoing larger Goodrich Aerostructures – North Campus – Eastern Parcel A (Case Number T10000011095) investigation under the oversight of the RWQCB. Onsite soil and groundwater sampling indicted that:

Land Parcels
o Thallium was detected in soil at 364 Bay Boulevard (Rohr Property ID 9) above the residential RSL, but below the commercial/industrial RSL. Based on proposed commercial use further investigation is not warranted at this time.
o Arsenic was detected in groundwater was slightly above the MCL of 0.010 mg/l at 360 and 368 Bay Boulevard (Rohr Property IDs 8 and 6). Groundwater in this area is not used for potable purposes, Further evaluation of arsenic in groundwater is not warranted at this time.

Parcel A
o The results of the site investigations identified the following COPCs in soil including VOCs, TPH, SVOCs, PCBs and the organochlorine pesticide, DDT. Of the VOCs, TCE and PCE were the primary VOCs detected in soil. The maximum VOC soil gas concentrations reported within the vicinity of the Project footprint were: Chloroform: 39,000 µg/m3; PCE: 11,000 µg/m3; and TCE:
3,000,000 µg/m3.

In order to manage the RECs on Parcel A
o Impacted soil at the northern end of Building 29 will be excavated and disposed offsite. o PSIP Wohl will install a SSDS to address VOCs in soil gas that are present beneath the slab in Building 29 and a RMP will be prepared and implemented to address potential future vapor intrusion risk to building occupants.

Controlled Recognized Environmental Condition
A controlled recognized environmental condition (CREC) refers to a REC 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). The following was identified during the course of this assessment:
• Partner did not identify CRECs during the course of this assessment.

Historical Recognized Environmental Condition
A historical recognized environmental condition (HREC) refers to a previous release of hazardous substances or petroleum products affecting the 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 subject property to any controls (for example, activity and use limitations or other property use limitations). The following was identified during the course of this assessment: Partner did not identify any HRECs during the course of this assessment. • Partner did not identify HRECs during the course of this assessment.

Business Environmental Risk
A Business Environmental Risks (BER) is 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. The following was identified during the course of this assessment:
• Due to the age of the subject property buildings, there is a potential that asbestos-containing material (ACM) and/or lead-based paint (LBP) are present. Should these materials be replaced, the identified suspect ACMs would need to be sampled to confirm the presence or absence of asbestos prior to any renovation or demolition activities to prevent potential exposure to workers and/or building occupants.
• According to the ERIS Database, PFAS were detected in well data from groundwater monitoring wells mapped on the Rohr South Campus in 2022. There is no current data for the subject property.

Currently, there are no legally enforceable federal or State of California criteria for PFAS. In October 2019, the DoD issued a memorandum identifying risk-based screening levels calculated using the USEPA Regional Screening Level (RSL) calculator for PFOA, PFOS, and PFBS in groundwater and soil.

Significant Data Gaps
No significant data gaps affecting the ability of the Environmental Professional to identify a REC were encountered during this assessment.

Conclusions and Recommendations
Partner has performed a Phase I ESA in conformance with the scope and limitations of ASTM Practice E1527- 13 and E1527-21 of 795 H Street and 360, 364, 368 and 390 Bay Boulevard, Chula Vista, CA 91910, Chula Vista, San Diego County, California (the “subject property”). Any exceptions to, or deletions from, this practice are described in Section 1.5 of this report.

This assessment has revealed evidence of RECs and BERs in connection with the subject property. Based on the conclusions of this assessment, Partner recommends the following:
• Continue to abide by the requirements of Cleanup and Abatement Order No. R9-2021-0042 (CAO) as directed by RWQCB for the former Rohr facility.
• Manage onsite activities with the existing Demolition and Environmental Management Plan (DEMP). • Manage future vapor intrusion risk to building occupants with pending Risk Management Plan (RMP).

1.0 INTRODUCTION
Partner Engineering and Science, Inc. (Partner) has performed a Phase I Environmental Site Assessment (ESA) in conformance with the scope and limitations of ASTM Standard Practice E1527-13 and E1527-21 and the Environmental Protection Agency Standards and Practices for All Appropriate Inquiries (AAI) (40 CFR Part 312) for the property located at 795 H Street and 360, 364, 368 and 390 Bay Boulevard, Chula Vista, CA 91910, Chula Vista, San Diego County, California (the “subject property”). Any exceptions to, or deletions from, this scope of work are described in the report.

1.1 Purpose
The purpose of this ESA is to identify existing or potential Recognized Environmental Conditions (as defined by ASTM Standard E1527-13 and E1527-21) affecting the subject property that: 1) constitute or result in a material violation or a potential material violation of any applicable environmental law; 2) impose any material constraints on the operation of the subject property or require a material change in the use thereof; 3) require clean-up, remedial action or other response with respect to Hazardous Substances or Petroleum Products on or affecting the subject property under any applicable environmental law; 4) may affect the value of the subject property; and 5) may require specific actions to be performed with regard to such conditions and circumstances.

This ESA was performed to permit the User to satisfy one of the requirements to qualify for the innocent landowner, contiguous property owner, or bona fide prospective purchaser limitations on scope of Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) (42 U.S.C. §9601) liability (hereinafter, the “landowner liability protections,” or “LLPs”). ASTM Standard E1527-13 constitutes “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined at 42 U.S.C. §9601(35)(B).

1.2 Scope of Work
The scope of work for this ESA is in accordance with and to the extent necessary to achieve the goal of the requirements set forth in the ASTM Standard E1527-13 and E1527-21. This assessment included: 1) a property and adjoining site reconnaissance; 2) interviews with key personnel; 3) a review of historical sources; 4) a review of regulatory agency records; and 5) a review of a regulatory database report provided by a third-party vendor. Partner contacted local agencies, such as environmental health departments, fire departments and building departments to obtain readily ascertainable information to determine any current and/or former hazardous substances usage, storage and/or releases of hazardous substances on the subject property. Additionally, Partner researched readily available information on the presence of activity and use limitations (AULs) at these agencies. As defined by ASTM E1527-21, AULs include both legal (that is, institutional) and physical (that is, engineering) controls that may include 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, or surface water on the subject 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 (IC/ECs), are

Please refer to Figure 1: Site Location Map, Figure 2: Site Plan, Figure 3: Topographic Map, and Appendix A: Site Photographs for the location and site characteristics of the subject property.

2.2 Current Property Use
The subject property, referred to as Land Parcels and Parcel A, is located on the former North Campus of Rohr, Inc. (Rohr), a Collins Aerospace Company. Rohr is a large aircraft parts manufacturing facility that has been operating since 1941. The Rohr facility address is 850 Lagoon Drive. In 2022, Rohr sold the Land Parcels and Parcel A to PSIP Wohl for redevelopment. A description of the subject property is presented below:

Land Parcels
The northern portion of the subject property, referred to as the Land Parcels, consisted of three parcels of vacant land covered with low-lying vegetation. The three parcels were owned by Rohr, Inc. from 1999 to 2020. The parcels are identified by site addresses and Rohr Inc. ID numbers: 360 Bay Boulevard (Rohr Property ID 8); 364 Bay Boulevard (Rohr Property ID 9); and 368 Bay Boulevard (Rohr Property ID 6). The Land Parcels are surrounded by a fence. Access to the subject property is via a gate along Bay Boulevard.

Parcel A
Parcel A consists of two industrial parcels located to the south of the Land Parcels and separated by G Street.
• The northern parcel is located on the north side of G Street at 390 Bay Boulevard (APN 567-022- 30-00) and developed with Rohr Buildings 99 and 100.

• The southern parcel is located on the south side of G Street at 795 H Street (APN 571-330-35-00) and developed with Rohr Building 29. Building 29 consists of 281,597 square feet constructed between 1957 and 1962. The building interior consists of former office, tooling, laboratory, and photo lab areas and hydraulic powered crane systems. A former crane pit is located on the north side of the building. The pit is reported to be approximately 18-inches deep and was filled with rain water. Former testing labs, hydraulic pumps, and storage areas were located on the north side of the building. The building was vacant from September 2020 until November 2021. In the summer of 2021, approximately 50,000 square feet of mezzanine was removed from the east wall of the building. The site is currently leased to Marine Group and Proactive Logistics. Marine Group leases approximately 1,500 square feet to store motor homes on the south side of Building 29. Proactive Group Logistics leases approximately 150,000 square feet in the central portion of Building 29 for storage. The northern portion of the Building 29 is currently not in use. In April 2023, Wohl intends to demolish the northern 24,000 square feet of Building 29 to construct a new loading dock. Prior to the new construction, remedial activities including removing volatile organic compounds (VOCs) impacted soil beneath the northern portion of the building and installing and operating a sub-slab depressurization system (SSDS) to mitigate VOCs in soil vapor from impacted groundwater will be completed as part of the Cleanup and Abatement Order No. R9-2021-0042 (CAO) discussed further below.

The subject property is zoned Local Coastal Program Specific Plan Area for industrial development by the City of Chula Vista.

The subject property is identified in the regulatory database report of Section 4.2.

2.3 Current Use of Adjacent Properties

2.4 Physical Setting Sources

2.4.1 Topography
The 2021 United States Geological Survey (USGS) National City, California Quadrangle 7.5-minute series topographic map was reviewed for this ESA. According to the contour lines on the topographic map, the subject property is located at approximately 25 feet above mean sea level (MSL). The contour lines in the area of the subject property indicate the area is sloping toward the southwest.

A copy of the most recent topographic map is included as Figure 3 of this report.

2.4.2 Hydrology
According to topographic map interpretation, groundwater in the vicinity of the subject property is inferred to flow toward the southwest.

According to 2017 groundwater sampling data at the subject property and topographic map interpretation, the depth to groundwater in the vicinity of the subject property is inferred to be approximately 20 to 35 feet below ground surface (bgs) and flows to the west (Haley & Aldrich, Inc., January 11, 2018).

The nearest surface water in the vicinity of the subject property is the San Diego Bay located approximately

0.40-miles west of the subject property. No settling ponds, lagoons, surface impoundments, wetlands or natural catch basins were observed at the subject property during this assessment. A stormwater ditch was located adjacent to the west of the subject property.

2.4.3 Geology/Soils
The site is located in the Peninsular Ranges geomorphic province. The Peninsular Ranges are a northwestsouthwest oriented complex of blocks separated by similarly trending faults. They extend from the Transverse Ranges and the Los Angeles Basin south to the Mexican border and beyond to the tip of Baja California and are bounded on the east by the Colorado Desert and the Gulf of California. The Peninsular Ranges contain minor Jurassic and extensive Cretaceous igneous rocks associated with the Nevadan plutonism. Marine Cretaceous sedimentary rocks are well represented and post-Cretaceous rocks form a restricted veneer of volcanic, marine, and nonmarine sediments.

According to a 2017 investigation at the subject property, the subject property is underlain by artificial fill and the Bay Point and San Diego Formations. Soil at the site is a mixture of interbedded sand, silt, and clay (Haley & Aldrich, Inc., January 11, 2018).

2.4.4 Flood Zone Information
Partner performed a review of the Flood Insurance Rate Map (FIRM), published by the Federal Emergency Management Agency (FEMA). According to Community Panel Number 06073C1913H, dated December 20, 2019, the northern portion of the subject property appears to be located in Zone X (unshaded), defined as an area of minimal flood hazard. The southern portion of the subject property (from the central portion of APN 571-330-35-00 (795 H Street/Rohr Buildings 29)) is located in Zone X (shaded), defined as an area with

0.2% annual chance flood hazard.

A copy of the reviewed flood map is included in Appendix B of this report.

Land Parcels
According to available historical sources, the Land Parcels was undeveloped or vacant land in 1904. From 1928 to 1949, the Land Parcels were agriculturally developed land. From 1953 to at least 1985, the Land Parcels were developed with multiple small industrial structures. Businesses reportedly included aircraft parts manufacturing, refrigeration unit repair, storage, junkyards, and a veterinary hospital. According the city directories, former tenants on the subject property appeared to include B&H Metal Co., Hammer Benj W, Lyman Jos, Mansell Marine Inc. engine exchange, Mansell Earl A (1955-1960); South Bay Vet Hospital (1956-1966); Post Aircraft Co. Inc. (1960); Yarie Richard J GA27905, Post Aircraft Co GA (1961); A&R Used Auto Parts wreckers, South Bay Marine boat sales & repair (1965); Ultra Plastics (1966); A&R Used Truck Parts, SD Pump & Compressor Supply (1971-1986); Thermo King (1975); Durrant Marcia A, Elliott Carol (1979-1982); Edwards Hugh L (1980-1986); and Jennings Dale J (1986).

According to the H&A July 2022 Revised Baseline Human Health Risk Assessment, after 1953, the Land Parcels at 360, 364, and 368 Bay Boulevard were developed with mixed commercial/industrial and residential use. Businesses that occupied these parcels included aircraft parts manufacturing, refrigeration unit repair, storage, junkyards, and a veterinary hospital. 360 Bay Boulevard was formerly used for auto maintenance and repair, auto dismantling, and salvaging that included a gold ore extraction/recovery operation. By the mid-1980s, the properties were acquired by the City of Chula Vista and business operations ceased. In 1999, Rohr acquired the Land Parcels and they have remained vacant since.

Parcel A - Buildings 99/100
According to available historical sources, Parcel A currently was developed agriculturally developed land from 1928 to 1949. From 1953 to 1966, the site was developed with a trailer park and a parking lot. By 1976, the trailer park was no longer present. By 1980, Buildings 99 and 100 were constructed on the property. According the city directories, former tenants on the subject property appeared to include Duvall Co. (1956-1961)Harbor Trailer Park, Maksor Trailer Park (1956-1975); Lawless Detat Diesel (1980) and Valley Det Dies All (1985). According to the H&A July 2022 Revised Baseline Human Health Risk Assessment, Valley Detroit Diesel repaired semi-truck engines at Buildings 99 and 100 starting in 1978. In 1986, Rohr purchased Buildings 99 and 100 from Valley Detroit Diesel and used the buildings primarily for administrative purposes.

Test laboratories were housed in Building 100 until 2021.

Parcel A - Building 29
According to available historical sources, Parcel A currently developed with Building 29, was agriculturally developed land in 1928. Several small structures were located on the northeast corner and southern portion of the parcel located south of G Street. By 1949, the parcel was developed with several structures on the central and southern (Building 28) portions of the site. By 1964, the parcel was developed with a large building (Building 29), a smaller building (Building 28) on the south side of the site, and several out-buildings on the northeast corner of the parcel as part of the Rohr facility. Building 28 was used as a cafeteria and a warehouse. By 1996, Building 28 had been removed and was replaced with a parking lot. According to the H&A July 2022 Revised Baseline Human Health Risk Assessment, Building 29 was constructed by Rohr in phases beginning in about 1957 to 1962. Building 29 was covered under the Rohr North Campus address of 850 Lagoon Drive. The building was used for tooling and machining and office space. The Maintenance Department for the facility was located in the northern portion of the building. The building also formerly housed laboratories, kitting, an Aftermarket Spares Warehouse, Service Center and FAI repairs, storage, tool calibration, product development, and office space. Historical uses for the parcel prior to Rohr included agriculture, a possible lumber yard, and residential.

In 2020, Rohr sold the Land Parcels and Parcel A to PSIP Wohl.

Summary of Communication:

Partner received a reply from the DEH stating they have records for the subject property address.

Land Parcels
• In the late 1980s, the environmental due diligence conducted by Rohr identified recognized environmental conditions (RECs) at the subject property and the adjacent property to the north.

Regulatory cases were opened with the DEH for subject property (360 Bay Boulevard) and the adjoining properties to the north (350, 340 and 390 Bay Boulevard and 798 Lagoon Drive), commonly referred to as Rohr IDs 4, 11, 10, 5, and 8; the Bay Boulevard Parcels; or Vacant Bay Boulevard Properties. Between 1987 and 2007, soil and groundwater investigations, some soil remediation and groundwater monitoring was conducted on the parcels under the oversight of the DEH. No Further Action (NFA) Letters were issued by DEH in 2001, 2004, 2006, and 2007. • Between 1987 and 2001, environmental investigations were conducted at the subject property (350- 360 Bay Boulevard – DEH Establishment # H26520-001). The investigation covered the subject property and the adjoining property to the north located on Bay Boulevard (350, 360, and 364 Bay Boulevard). The former use of the site included an auto repair/salvage yard (with gold ore extraction) and the storage of used appliances. The investigations included soil and groundwater samples for lead, pesticides and polychlorinated biphenyls (PCBs). Lead and Total Petroleum Hydrocarbons (TPH) was identified in soil. Trichloroethene (14 micrograms per liter (µg/l in MW-2) and Chloroform (3-5 µg/l in MW-1 to MW-3) were identified in three wells onsite and the adjacent Rohr site (located adjacent to the west, southwest, south). Concentrations were detected above the recommended California State Action Level of 5 µg/l. Groundwater impacts were thought to have originated offsite. It was not clear from the documents reviewed how long groundwater continued to be monitored. Pesticides and PCBs were detected at relatively low concentrations (below concentrations requiring action).
• On January 9, 2001, a County of San Diego County DEH Voluntary Assistance Program (VAP) Application was submitted by Rohr, Inc. and received on January 9, 2001 for Establishment # H26520-001 (350-360 Bay Boulevard). The project was described as the excavation of approximately 1,500 cubic yards of shallow soil impacted by lead. The soil was reclassified as non-hazardous waste by DTSC and the City would like the lead-containing soil to the Otay Class I Landfill. Rohr, Inc. was

requesting review of the work plan and issuance of a no further action (NFA) at the conclusion of confirmation sampling.
• According to the Case Closure Summary dated September 6, 2001, the subject property was identified as a Vacant Lot (350-360 Bay Boulevard) owned by the City of Chula Vista. Previous site uses included agricultural farming, auto wreaking, and auto repair. Lead contaminated soil was encountered during an investigation. Approximately 800 cubic yards of lead contaminated soil were excavated to a depth of 2 feet and disposed offsite to the Otay Class I Landfill. Confirmation soil samples were collected from the perimeter and the floor of the footprint of the excavation at statistically random locations. The consultant concluded that the mean total lead concentration insitu soils at the site was 54 milligram per kilogram (mg/kg) and the upper 95% confidence interval was 71 mg/kg, both lower than the residential (PRG) of 400 mg/kg. The consultant concluded that this soil contamination did not present a human health risk at the subject property. The proposed future use of the site was listed as light industrial with paved areas and building on concrete slabs. • On September 17, 2001, DEH issued a No Further Action (NFA) letter to the City of Chula Vista following the removal of 800 cubic yards lead contaminated soil on February 5, 2001. A copy of the NFA letter is provided in Appendix B.
• In 2016 and 2017, an application and boring completion report were submitted on behalf of Rohr, Inc. for the advancement of six borings at the Vacant Bay Boulevard Properties (Bay Boulevard) to collect soil and groundwater samples.

Parcel A – 390 Bay Boulevard and Building 29
Monitoring well permit applications and technical reports were available from 1986 to 2020. Most recently, on September 28, 2020, DEH approved a Monitoring Well Destruction Permit for Haley & Aldrich to destroy three monitoring wells and two transducers at 390 Bay Boulevard. According to the January 2021 Haley & Aldrich Well Destruction Report, the Wells DB-2 and DB-5 and the pressure transducers OW-1 and OW-2 were destroyed on October 19 and October 20, 2020. Well DB-5 was destroyed on November 16 and 17, 2020.

Summary of Communication:

The subject property was identified on the GeoTracker database as part of ongoing investigations associated with Rohr, Inc. and the Cleanup and Abatement Order (CAO) No. R9-2021-0042. The Rohr facility has been divided into three parts: Parcels A, B, and C. Buildings 29, 99, and 100 were investigated as part of Case Number T10000011095 Goodrich Aerostructures – North Campus – Eastern Parcel A at 850 Lagoon Drive. The Land Parcels at 360, 364, and 368 Bay Boulevard were formerly investigated as Parcel C (Case Number T0608199629). Upon the sale of Parcel A and the Land Parcels to PSIP Wohl, the Land Parcels (APNs 567-022-28, 567-022-31, and 567-022-33) were added to Parcel A and included in the H&A July 2022 Revised Baseline Human Health Risk Assessment.

A summary of pertinent information is summarized below:
• Formerly Thermo King (Case Number T0608199629) – 340 Bay Blvd.

In May 1992, TorStan Inc. completed a Lead, Pesticide, and Polychlorinated Biphenyl Soil Sampling Report for 350-360 Bay Boulevard. TorStan Inc. concluded that there was soluble lead contamination above the CCR STLC throughout the top six inches of soil at 350-360 Bay Boulevard. See Section 4.1.1. • Goodrich Aerostructures – North Campus – Eastern Parcel A (Case Number T10000011095) – 850 Lagoon Drive
On October 5, 2021, Raytheon Technologies Corporation on behalf of Rohr, Inc. (Rohr) provided the RWQCB written notification per the Cleanup and Abatement Order (CAO) No. R9-2021-0042 that Rohr Inc. had sold the portion of Parcel A occupied by Buildings 29, 99 and 100 and 360, 364 and 358 Bay Boulevard to PSIP Wohl Bay Boulevard, LLC, a Delaware limited liability company on September 25 and 28, 2020.

This equipment has been removed. Figures 2, 3, and 4 in the CSM depicts the former operational features,

including buildings, ASTs, USTs, underground vessels, vaults, paint booths, degreasers, hydraulic equipment, and maintenance and storage areas located at the subject property.

According to the Revised CSM, the environmental investigations were conducted to evaluate chemical impacts to soil, soil gas, and groundwater as well as indoor air screening (Building 29). The results of the site investigations identified the following chemicals of potential concern (COPCs) in soil within the Project footprint: VOCs, Total Petroleum Hydrocarbons (TPH), semi-volatile organic compounds (SVOCs), PCBs and the organochlorine pesticide, DDT. Metals concentrations within the Project footprint fall within background ranges. Trichloroethene (TCE) and tetrachloroethene (PCE) were the primary VOCs detected in soil in Project footprint and vicinity. The maximum concentrations of TCE and PCE were reported in boring B29-23 (37,800 µg/kg) and B29-28 (1,260 µg/kg), respectively. The maximum PCB (Aroclor 1260) concentration reported for soil in the Project footprint was 1,300 µg/kg in boring B29-05 (sample ID B29-05-2). This sample was also reported to contain low concentrations of TPH (in the oil carbon range [C32-C44]; 185 mg/kg), certain SVOCs (maximum concentration was for fluoranthene, 0.21 mg/kg) and DDT ( 0.021 mg/kg). The maximum VOC soil gas concentrations reported within the vicinity of the Project footprint were: Chloroform: 39,000 µg/m3; PCE: 11,000 µg/m3; and TCE: 3,000,000 µg/m3.

On July 8, 2022, Haley & Aldrich, on behalf of Rohr, Inc., prepared an update to the Revised Baseline Human Health Risk Assessment (HHRA) for North Campus Parcel A, Chula Vista, CA (Site ID #2092900) and dated July 8, 2022. The HHRA stated that Rohr was in the process of selling portions of its facility that occupied approximately 82 acres. The Site had been divided into three parts: Parcels A (the subject property), B (adjoining property to the west), and C (adjoining property to the northwest). In September 2020, Rohr sold Parcel A that includes Buildings 29, 99, and 100 (assessor parcel number [APN] 567-022-30 and the eastern portion of APN 571-330-29) to PSIP Wohl. Wohl had also purchased the vacant parcels (Also referred to as the Land Parcels) at 360, 364, and 368 Bay Boulevard (APNs 567-022-28, 567-022-31, and 567-022-33). These parcels, formerly included in Parcel C, were now also included in the Update to the Revised HHRA. With these added parcels, Parcel A occupied approximately 14.7 acres.

Historical chemical sources are coincident with former Site areas associated with long-term chemical usage.

A comprehensive summary of previous investigations is provided in HHRA and covers:
• 1986-1996 Fuel underground storage tanks (USTs) closures at Buildings 99 and 100 • 1987-2001 350-360 Bay Boulevard Site Assessments related to the lead soil, PCBs, and VOCs • 1998 Adrian Brown Phase I of the Rohr facility
• 1998 and 1999 San Diego Formation Aquifer Testing
• 1999 Blanchard Grinder UST closure at Building 29
• 2013 Supplemental Remedial Investigation by URS
• 2016 Haley & Aldrich Phase I and IIs at Buildings 29, 99, and 100 and the Vacant Bay Boulevard Properties
• 2018 Sub-Slab and Focused Soil Vapor Survey at Buildings 29, 99, and 100 • 2018-2019 Indoor air screening in Building 29
• 2020 Haley & Aldrich Data Gap Assessment to further characterize the nature and extent of VOCs in soil and groundwater and conduct some step-out sampling in areas where arsenic and PCBs had been detected above screening levels during the Phase II • 2020 GSI Environmental, Inc. Phase I Screening Investigation on Parcel A • 2020 Partner Engineering and Science, Inc. Phase I for 350-368 Bay Boulevard • 2022 Haley & Aldrich Data Gap Assessment
Based on the results of the HHRA, Haley & Aldrich concluded:

Building 29 – No remediation or mitigation was necessary to protect the on-site landscaper.

Based on sub-slab soil vapor data for the on-site commercial/industrial worker, the cumulative ILCR was greater than the acceptable cumulative incremental lifetime cancer risks (ILCR) threshold of 1 x 10-5 and the total hazard index (HI) was greater than the acceptable total HI of 1 for the on-site commercial/industrial worker. Bromodichloromethane, chloroform, cis-1,2-dichloroethene (cis-1,2-DCE), tetrachloroethene (PCE), and trichloroethene (TCE) were driving the risk. Heath-based remediation goal (HBRGs) were derived for these chemicals of potential concern (COPCs) in soil vapor to reduce estimated health risks for the on-site commercial/industrial worker from exposure to inhalation of indoor air for Building 29. The soil vapor HBRGs for bromodichloromethane, chloroform, cis-1,2-DCE, PCE, and TCE were 70, 80, 100, 370, and 350 micrograms per cubic meter (µg/m3). Haley & Aldrich stated that the Owner would be installing a sub-slab depressurization system (SSDS) beneath Building 29 as a vapor intrusion mitigation measure and implementing an Risk Management Plan (RMP).

during excavation to construct the new loading dock on the north end of Building 29. The HBRG for TCE in this area is 1.5 mg/kg.

It was anticipated that the DEMP would be implemented in 2023.

The DEMP provides guidelines and procedures that the contractor shall follow for managing concrete, asphalt pavement, and soil generated during the Project. It also describes procedures for addressing new environmental conditions (NECs) that may be identified following demolition and impacted soil management during construction.

The DEMP indicated:
• PSIP Wohl had made improvements to the building that included installing a new heating, ventilation, and air conditioning system and sealing and polishing the concrete floor. PSIP Wohl was required through the Purchase and Sale Agreement with Rohr to install a sub-slab depressurization system (SSDS) to address volatile organic compounds (VOCs) in soil gas that are present beneath the slab in Building 29. A separate Work Plan will be submitted that will describe the design, installation, and monitoring of the SSDS to address soil gas beneath the building slab.

The DEMP indicated that in addition to the above documents, others will be prepared for Parcel A specific to Cleanup and Abatement Order No. R9-2021-0042 (CAO). These included: 1) Site Soil Cleanup Levels Report (Directive C.4.a), and 2) Site Soil and Soil Gas Remedial Alternatives Report (Directive C.4.b)/Remedial Action Plan (RAP) (Directive C.5.a).

The subject property is identified in the regulatory database report, as discussed below:
• Rohr Inc., Lawless, Valley Detroit Diesel, (ERIS Map ID: 1) at 390 Bay Boulevard, is listed in the HAZ San Diego, CHMIRS, HHSS, HAZNET, HIST Manifest, and HIST Tank databases. As discussed in Section 4.1.3, this facility which includes the subject property, is being investigated under the oversight of the RWQCB. The investigation is ongoing.
• Rohr, Inc., North Campus – Parcel A, BF Goodrich, UTC Aerostructures, (ERIS Map ID: 7, 12, 18, 21) at 850 Lagoon Drive and foot of H Street, is located adjacent to the west, south, and southwest and hydrologically cross- to down-gradient of the subject property. This site was identified in the CDO/CAO, Calsites, CERCLIS, CERCLIS NFRAP, Emissions, EnviroStor, Cleanup Site, HHSS, HIST Tank, AST, CERS Tank, HAZ San Diego, HAZ TSD, UST, LUST, PCB and RCRA databases. As discussed in Section 4.1.3, this facility which includes the subject property, is being investigated under the oversight of the RWQCB. The investigation is ongoing. According to the GeoTracker database, the regulatory status is listed as Open-Site Assessment as of November 17, 2017. Industrial activities and historical chemical use on Parcel A were more limited compared to the main manufacturing portions of the facility located on Parcel B and the former South Campus located to the west and southwest.

Building 29 was primarily used for tooling, machining, and office space. At one time, the northernmost portion of the building served as the maintenance department. Rohr purchased Buildings 99 and 100 in 1986 and primarily used them for administrative purposes. Prior to Rohr’s ownership, Parcel A had other uses. It is reported that Parcel A buildings were previously equipped with USTs containing gasoline, diesel and waste oil, two wastewater clarifiers, ASTs, a paint spray booth, solvent degreasers, and other equipment. Soil, soil vapor and groundwater investigations are ongoing at Parcel A. According to a April 2021 Revised Conceptual Site Model (CSM) report prepared by Haley & Aldrich for Parcel A, VOC releases have migrated through the soil to groundwater, resulting in a groundwater plume that extends westward below Parcel B (adjoining to the west).
• City of Chula Vista – Comm Dev Dept (ERIS Map ID: 1) at 388-390 Bay Boulevard, is listed in the HAZNET databases. The facility is listed in the HAZNET database for generating state-regulated waste including oil/water separation sludge that was manifested for off-site disposal in 1985 and 1987.

• Rohr Inc., South Campus (ERIS Map ID: 18), at the south of H Street, is located adjoining to the southwest and hydrologically down-gradient of the subject property. The South Campus was formerly developed with multiple buildings operated by Rohr Inc. dating back to 1941, where manufacturing of engine components for use in the aviation and aerospace industry was performed (similar to the subject property). Chemicals stored at the South Campus Property and used during manufacturing operations have been found in the soil, soil gas, and groundwater as reported in site environmental investigation reports and groundwater monitoring reports. The group of chemicals discharged include, but are not limited to, VOCs, metals, petroleum hydrocarbons, PAHs, and PCBs.

In 1998, the SDRWQCB issued CAO No. 98-08 to Rohr, Inc. that requires the cleanup and abatement of wastes discharged from Rohr’s manufacturing operations located at 850 Lagoon Drive (North Campus Property and South Campus Property). On July 13, 1999, the City of Chula Vista, the Redevelopment Agency of the City of Chula Vista, the Port of San Diego, and Rohr entered into a Relocation Agreement. Thirty-eight acres of Rohr-owned property were transferred to the Port of San Diego and a 28-acre lease of Port tidelands was terminated as part of this Relocation Agreement for the entire South Campus site. In 2002, Rohr vacated the South Campus Property and consolidated manufacturing operations to the North Campus Property (subject property). In 2007, the Port of San Diego demolished all buildings at the South Campus. In 2014, the SDRWQCB issued CAO No. R9-2014-0019, which requires the cleanup or abatement of all wastes discharged to soil, soil gas, and groundwater from the manufacturing operations at the South Campus Property.

CAO No. R9-2014-0019 supersedes CAO No. 98-08. Implementation of the soil Remedial Action Plan (RAP) is currently underway and has not yet received final regulatory closure. Groundwater monitoring and remedial efforts are ongoing.
• PFAs GW (ERIS Map ID: 17, 35, 37) located south of H Street, is located to the southwest and hydrologically down-gradient of the subject property. According to the ERIS Database, PFAS were detected in well data from groundwater monitoring wells mapped on the Rohr South Campus in 2022. Currently, there are no legally enforceable federal or State of California criteria for PFAS. In October 2019, the DoD issued a memorandum identifying risk-based screening levels calculated using the USEPA Regional Screening Level (RSL) calculator for PFOA, PFOS, and PFBS in groundwater and soil.

(December 28, 2020) From the late 1980s to 2020, numerous environmental assessments have been performed and are currently ongoing at the subject property and the three adjacent properties to the north, collectively known as the Bay Boulevard parcels. The subject property is identified in these investigations by the following site addresses and Rohr Inc. ID numbers: 350 Bay Boulevard (Rohr Property ID 5); 360 Bay Boulevard (Rohr Property ID 8); 364 Bay Boulevard (Rohr Property ID 9); and 368 Bay Boulevard (Rohr Property ID 6); and the adjoining property to the north 350 Bay Boulevard (Rohr Property ID 5).

In July 2016, Haley and Aldrich, Inc. prepared a Phase I ESA for the subject property and adjacent properties to the north for Rohr Inc. (Rohr), the property owner. Rohr was proposing to sell the Bay Boulevard parcels.

The subject property was vacant land at the time of the assessment.

Haley and Aldrich, Inc. reported that in the late 1980s, Rohr considered purchasing the Bay Boulevard parcels for development of its corporate headquarters. As a result of environmental due diligence, recognized environmental conditions (RECs) were identified. In the late 1980s and 1990s, assessments of soil and groundwater conditions were conducted and four regulatory cases were opened for Rohr IDs 4, 11, 10, 5 and 8 through the Voluntary Assistance Program (VAP) with the San Diego County Department of Environmental Health (DEH). Some degree of remediation of soil and groundwater monitoring were conducted on the parcels. In 2006 and 2007, the DEH provided no further action (NFA) letters (three) for the open cases located adjacent to the north of the subject property, contingent on continued commercial/industrial property use. A fourth NFA letter was believed to have been issued for Rohr IDs 5 and 8 (the subject property at 350-360 Bay Boulevard/ DEH Case #H26520-001), but was not obtained by Haley and Aldrich, Inc. Partner obtained a copy of the NFA (see Appendix B). Haley and Aldrich, Inc.

Groundwater - 368 Bay Boulevard (Rohr Property ID 6)
• Chloroform was detected in the groundwater sample from boring BB-23 at a concentration of 0.34 J µg/l, which is below the MCL of 80 µg/l and the ESLs. No other VOCs were detected in groundwater analyzed from boring BB-23.
• The arsenic concentration (0.0112 mg/l) was slightly above the MCL of 0.010 mg/l.

In December 2020, Partner completed an ESA for the vacant parcels considered part of the subject property.

The assessment was performed on a larger parcel of land that included the adjoining property to the north known as 350 Bay Boulevard (Rohr Property ID 5). The subject property consisted of four parcels of vacant land covered with low-lying vegetation. The four parcels were owned by Rohr, Inc. since 1999.

The following REC was identified:
• The subject property and adjacent properties are part of the ongoing larger Goodrich Aerostructures – North Campus – Eastern Parcel A (Case Number T10000011095) investigation under the oversight of the RWQCB. Onsite soil and groundwater sampling indicted that:

Thallium was detected in soil at 364 Bay Boulevard (Rohr Property ID 9) above the residential RSL, but below the commercial/industrial RSL.

Arsenic was detected in groundwater was slightly above the MCL of 0.010 mg/l at 360 and 368 Bay Boulevard (Rohr Property IDs 8 and 6).

The investigation was ongoing and considered a REC and additional sampling was proposed for the adjacent parcels to the northwest.

In August 2020, GSI Environmental Inc. (GSI) prepared a Phase I ESA for the subject property. According to the 2020 GSI report:
• Parcel A consisted of two parcels bifurcated by G Street and totaling 11.82-acres. The site was part of the Rohr aircraft parts manufacturing facility that had been in operation since 1941. The area north of G Street (390 Bay Boulevard; APN No. 567-022-30-00) was developed with Buildings 99 and 100. The area south of G Street (eastern portion of APN No. 571-330-29-00) was developed with Building 29. The Building 29 parcel utilized the address of 850 Lagoon Drive which was the Rohr Facility address.
• Historical uses of the parcels are described below:
o The parcel occupied by Buildings 99 and 100 was formerly used for agricultural development, trailer park, a hardware store, possible residences, and Lawless and Valley Detroit Diesel (repair of semi-trucks). The builds were constructed in 1980 and Rohr purchased the property in 1986 and conducted non-manufacturing activities on the parcel. Building 99 had been vacant since approximately 2018. This building was previously used for human resources, training, gym, medical services, and a print shop. Building 100 was utilized for R&D. Prior to Rohr’s purchase of the property, the building was utilized for servicing trucks and three service bays and a sump were in the building.
o The parcel occupied by Building 29 was formerly used for agricultural development and possible residences. A previous 2016 ESA report by Haley & Aldrich indicated that a lumber yard may have existed at the parcel. The City Directory list obtained by GSI identified Bay Surplus Boxes at 426 Bay Boulevard. The parcel was initially developed with former Building 28, a warehouse, from 1945 until it was demolished in the early 2000s. Building 29 was constructed in four phases between 1957 and 1962. Building 29 previously housed the Maintenance Department (northern third of the building to approximately Door 29-20), tooling with a machine shop, and offices.

Fromm 2013 to 2020, onsite operations consisted of primarily manufacturing related. By 2020, operations in the central portion of Building 29 were being shut down and the building was being used to store after-market equipment.
o Several historical features were identified at the subject property in previous environmental documents including underground storage tanks (USTs), underground vessels, ASTs, clarifiers, paint booths, sumps, and degreasers. By 2020, GSI observed a 500-gallon wastewater AST observed at the site. The other features had reportedly been removed or were inactive. GSI referenced a list of historical features included in Table 1 of Haley & Aldrich’s Conceptual Site Model (CSM) attached Appendix C of the GSI report.

Site investigation activities at the subject property began by 1986. Prior to 1998, the primary regulatory oversight agency was San Diego County Department of Environmental Health (DEH). In 1998, regulatory oversight agency was transferred to the Regional Water Quality Control Board (RWQCB) and a Corrective Action Order (CAO) was issued. Since that time numerous investigations have been conducted under the CAO and primary findings indicated that volatile organic compound (VOC) impacts to groundwater, soil vapor, and indoor air and limited arsenic-affected soil. The most recent investigations have been conducted

by Haley & Aldrich. No off-site properties were identified to have impacted environmental conditions at the site.

GSI identified the following RECs associated with the subject property:

Arsenic in soil at Building 29 - Arsenic was detected at concentrations above background at three locations (B29-02, B29-03, and B29-07) on the Building 29 parcel. Step-out borings were advanced at these locations (Haley & Aldrich, 2020b). Two of the step-out borings around boring B29-03 (B29-03A and -03B) and two around B29-07 (B29-07A and -07B) contained arsenic above the background level of 8 milligrams per kilogram (mg/kg) established for South Campus, but were below its groundwater protection level (GPL).

The arsenic concentration exceeded its GPL in one soil sample (B29-07A). GSI concluded that the arsenic results, in combination with other soil data collected around the northern portion of Building 29, indicated that the distribution of arsenic above screening levels was not constrained.

Limited polychlorinated biphenyls (PCBs) in soil at Building 29 - PCBs were detected at concentrations above the commercial/industrial screening level (SL) at one location (B29-05) in Building 29. PCBs were detected in the step-out borings around B29-05; however, concentrations were below commercial industrial SLs.

Based on the information reviewed, GSI concluded that PCB impacts appeared to be discrete and limited in extent.

VOCs in soil, groundwater, soil vapor, and indoor air – VOCs, primarily trichloroethene (TCE), are present beneath the site in soil, soil gas, and groundwater. Analytical results from B29‐23 and B29‐24 suggested that there are sources of TCE in soil beneath the former Maintenance Department of Building 29. TCE is present in Zone A and Upper Zone B groundwater beneath the Former Maintenance Department at concentrations that exceed the maximum contaminant level (MCL). TCE was detected in soil vapor samples across the site at concentrations up to 3,000,000 micrograms per cubic meter (µg/m3) (Haley & Aldrich, 2020b). Haley & Aldrich concluded that this data suggested that there may be residual sources in soil beneath the building. TCE was measured in indoor air in Building 29; concentrations were below response action levels for workers, but additional screening and engineering controls were recommended by Haley & Aldrich.

Mills and Lathes - VOCs were detected in soil samples from 7 of the 12 borings advanced at and near the former mills and lathes. Tetrachloroethene (PCE) and TCE were reported in soil samples from some borings.

Although none of the detected concentrations were present above the commercial/industrial SLs or GPLs, the presence of volatile constituents in soil could suggest these constituents exist in soil vapor at concentrations exceeding vapor intrusion environmental screening levels (VI-ESLs).

Metals in groundwater - Dissolved metals (antimony, arsenic, and thallium) concentrations exceeded MCLs at some on-site groundwater sampling locations. Although groundwater at the site was not utilized as a drinking water source, there was no information in the publicly available regulatory record that beneficial uses of groundwater, at and in the vicinity of the site, were re-designated to exclude use of groundwater for potable purposes.

No CRECs or HRECs were identified.

Six monitoring well covers were observed near the northeast corner of Building 99 during the Site reconnaissance. These wells appear to be related to a 1998/1999 investigation. Reportedly, the six wells and two borings were installed in this area during that investigation. GSI concluded that these wells/borings should be properly abandoned if not in use. Four wells have been properly abandoned and two remain in use.

GSI concluded that several RECs have been identified including known impacts to soil, groundwater, and soil vapor. TCE was detected in indoor air; however limited indoor air sampling has been conducted. Based on the presence of VOCs in the subsurface and previous detections of VOCs in indoor air, GSI recommended that a supplemental soil vapor assessment be conducted.

In September 2020, GSI prepared a Limited Phase II Screening Site Investigation Report for Wohl to assess the potential concentration and distribution of volatile organic compounds (VOCs) at the subject property.

This investigation was conducted at 17 locations within Building 29, 99, and 100. Soil samples were collected from 10 locations at approximately 5.5 feet bgs. and soil vapor samples were collected from 16 locations between approximately 3 and 5 feet below ground surface (bgs).

Based on the findings, GSI stated:

The current data are generally consistent with the data collected by Haley & Aldrich in 2018 both in terms of magnitude and chemicals of concern (i.e., PCE and TCE). The soil vapor results indicated PCE was detected at concentrations ranging from 4.7 to 5,800 micrograms per cubic meter (µg/m3); and TCE was detected at concentrations ranging from 5.9 to 2,900,000 micrograms per cubic meter (µg/m3).

Analytical results for the soil samples indicated that PCE was detected in PW-12 at a concentration of 4.7 micrograms per kilogram (µg/kg) at 1.5 feet bgs, and TCE was detected in PW-07 at a concentration of 23 µg/kg at 1.5 feet bgs. PCE and TCE were not detected above laboratory reporting limits (RLs) in other samples. PCBs (Aroclor-1260) were only detected in PW-11, at a concentration of 180 µg/kg. PCBs in other samples analyzed were not detected above RLs. No analytes were detected in soil samples at concentrations exceeding commercial screening levels or (for arsenic) background soil concentrations.

GSI concluded:

Building 29
The GSI data was generally consistent with the data collected by H&A in 2018 both in terms of magnitude and chemicals of concern (i.e., PCE and TCE). The detected concentrations of TCE did not indicate an increase in risk to building occupants when compared to H&A’s risk estimates. The analytical results for recent soil samples from Building 29 did not indicate a need for additional assessment.

Buildings 99 and 100
The soil vapor data collected within Buildings 99 and 100 did not indicate a need for additional assessment or vapor mitigation. The soil data collected within Buildings 99 and 100 did not indicate a need for additional assessment.

See Section 4.1.3 for discussion of management of RECs identified by GSI.

6.1 General Site Characteristics

6.1.1 Solid Waste Disposal
Solid waste generated at the subject property is disposed of in trash dumpsters located on the north side of the Buildings 99/100 (390 Bay Boulevard). Republic Services, an independent solid waste disposal contractor, removes solid waste from the subject property. No evidence of illegal dumping of solid waste was observed during the Partner site reconnaissance.

6.1.2 Sewage Discharge and Disposal
Sanitary discharges on the subject property are directed into the municipal sanitary sewer system. The City of San Diego services the subject property vicinity. No wastewater treatment facilities or septic systems were observed or reported on the subject property.

6.1.3 Surface Water Drainage
Stormwater is removed from the subject property primarily by sheet flow action across the paved surfaces towards stormwater drains located in the public right of way.

6.1.4 Source of Heating and Cooling
Electricity and natural gas are provided to the site vicinity by Southern California Edison (SCE) and the Southern California Gas Company.

6.1.5 Wells and Cisterns

6.1.7 Septic Systems
No septic systems were observed on the subject property during the Partner site reconnaissance.

6.1.8 Additional Site Observations
No additional general site characteristics were observed on the subject property during the Partner site reconnaissance.

6.2 Potential Environmental Hazards

6.2.1 Hazardous Substances and Petroleum Products Used or Stored at the Site At the time of the site visit, small quantities of hazardous materials including retail-size cleaning products, a portable diesel generator with a diesel AST (southeast side of Building 29/795 H Street), landscape equipment battery charging stations, and other general maintenance products were observed at the subject property. Hazardous materials observed at the subject property appeared to be stored properly with no evidence of spills or leaks. Based on the good housekeeping practices observed, and lack of stains or spills, the hazardous materials are not expected to represent an environmental concern. Partner did not observe indications of hazardous waste generation or storage onsite during the site reconnaissance.

6.2.2 Aboveground & Underground Hazardous Substance or Petroleum Product Storage Tanks (ASTs/USTs)
No evidence of current ASTs or USTs on the subject property was observed during the site reconnaissance other that the small diesel AST associated with the portable generator.

6.2.3 Evidence of Releases
No spills, stains or other indications that a surficial release has occurred at the subject property were observed.

6.2.4 Polychlorinated Biphenyls (PCBs)
Older transformers and other electrical equipment could contain PCBs at a level that subjects them to regulation by the U.S. EPA. PCBs in electrical equipment are controlled by United States Environmental Protection Agency regulations 40 CFR, Part 761. Under the regulations, there are three categories into which electrical equipment can be classified: 1) Less than 50 parts per million (ppm) of PCBs – “Non-PCB;” 2) 50 ppm-500 ppm – “PCB-Contaminated;” and, 3) Greater than 500 ppm – “PCB-Containing.” The manufacture, process, or distribution in commerce or use of any PCB in any manner other than in a totally enclosed manner was prohibited after July 2, 1979.

Several transformers were observed on the subject property. The transformers were not labeled indicating PCB content. No staining or leakage was observed in the vicinity of the transformers. SDG&E maintains ownership and operational responsibility for the transformers. Based on the good condition of the equipment, the transformer is not expected to represent an environmental concern.

6.2.5 Strong, Pungent or Noxious Odors
No strong, pungent or noxious odors were evident during the site reconnaissance.

6.2.6 Pools of Liquid
No pools of liquid on the subject property were observed during the Partner site reconnaissance.

6.2.7 Drains, Sumps and Clarifiers
No drains, sumps, or clarifiers, other than those associated with stormwater removal, were observed on the subject property during the site reconnaissance.

6.2.8 Pits, Ponds and Lagoons
No pits, ponds or lagoons were observed on the subject property.

6.2.9 Stressed Vegetation
No stressed vegetation was observed on the subject property.

6.2.10 Additional Potential Environmental Hazards
A former crane interior pit located on the north side of Building 29 was filled with rainwater at the time of the site visit. The area had been fenced off. According to Mr. Wohl, the pit was approximately 18 inches deep and was filled with rainwater due to the roof leaks. This area is in the planned demolition area. The water will be removed and disposed of prior to upcoming demolition activities.

6.3 Non-ASTM Services

6.3.1 Asbestos-Containing Materials (ACMs)
Asbestos is the name given to a number of naturally occurring, fibrous silicate minerals mined for their useful properties such as thermal insulation, chemical and thermal stability, and high tensile strength. The Occupational Safety and Health Administration (OSHA) regulation 29 CFR 1926.1101 requires certain construction materials to be presumed to contain asbestos, for purposes of this regulation. All thermal system insulation (TSI), surfacing material, and asphalt/vinyl flooring that are present in a building that have not been appropriately tested are “presumed asbestos-containing material” (PACM).

Based on the age of the subject property buildings, there is a potential that ACM is present.

6.3.2 Lead-Based Paint (LBP)
Lead is a highly toxic metal that affects virtually every system of the body. LBP is defined as any paint, varnish, stain, or other applied coating that has 1 mg/cm2 (or 5,000 ug/g or 0.5% by weight) or more of lead.

Congress passed the Residential Lead-Based Paint Hazard Reduction Act of 1992, also known as “Title X”, to protect families from exposure to lead from paint, dust, and soil. Under Section 1017 of Title X, intact LBP on most walls and ceilings is not considered a “hazard,” although the condition of the paint should be monitored and maintained to ensure that it does not become deteriorated. Further, Section 1018 of this law directed the Housing and Urban Development (HUD) and the US EPA to require the disclosure of known information on LBP and LBP hazards before the sale or lease of most housing built before 1978.

Based on the age of the subject property buildings, there is a potential that LBP is present.

6.3.3 Radon
Radon is a colorless, odorless, naturally occurring, radioactive, inert, gaseous element formed by radioactive decay of radium (Ra) atoms. The US EPA has prepared a map to assist National, State, and local organizations to target their resources and to implement radon-resistant building codes. The map divides the country into three Radon Zones, according to the table below:

EPA Radon Zones
EPA Zones Average Predicted Radon Levels Potential
Zone 1 Exceed 4.0 pCi/L Highest
Zone 2 Between 2.0 and 4.0 pCi/L Moderate
Zone 3 Less than 2.0 pCi/L Low
It is important to note that the EPA has found homes with elevated levels of radon in all three zones, and the US EPA recommends site-specific testing in order to determine radon levels at a specific location.

However, the map does give a valuable indication of the propensity of radon gas accumulation in structures.

Radon sampling was not conducted as part of this assessment. Review of the US EPA Map of Radon Zones places the subject property in Zone 3. Based upon the radon zone classification, radon is not considered to be an environmental concern.

6.3.4 Lead in Drinking Water
According to available information, a public water system operated by the Sweetwater Authority (SA) serves the subject property vicinity. According to the SA and the 2021 Annual Water Quality Report, water supplied to the subject property is in compliance with all State and Federal regulations pertaining to drinking water standards, including lead and copper. Water sampling was not conducted to verify water quality.

6.3.5 Mold
Molds are microscopic organisms found virtually everywhere, indoors and outdoors. Mold will grow and multiply under the right conditions, needing only sufficient moisture (e.g.in the form of very high humidity, condensation, or water from a leaking pipe, etc.) and organic material (e.g., ceiling tile, drywall, paper, or natural fiber carpet padding).

Partner observed accessible, interior areas for the subject property buildings for significant evidence of mold growth with the exceptions detailed in Section 1.5 of this report; however, this ESA should not be used as a mold survey or inspection. Additionally, this limited assessment was not designed to assess all areas of potential mold growth that may be affected by mold growth on the subject property. Rather, it is intended to give the client an indication as to whether or not conspicuous (based on observed areas) mold growth is present at the subject property. This evaluation did not include a review of pipe chases, mechanical systems, or areas behind enclosed walls and ceilings.

Indications of water damage from apparent roof leaks were observed during Partner’s visual assessment.

6.3.6 Wetlands
The subject property does not appear to be a designated wetland area, based on information obtained from the United States Fish and Wildlife Service. No surface impoundments, wetlands, natural catch basins, settling ponds, or lagoons are located on the subject property.

6.4 Adjoining Property Reconnaissance
The adjoining property reconnaissance consisted of observing the adjoining properties from the subject property premises. No items of environmental concern were visually identified on the adjoining properties during the site assessment, including hazardous substances, petroleum products, ASTs, USTs, evidence of releases, PCBs, strong or noxious odors, pools of liquids, sumps or clarifiers, pits or lagoons, stressed vegetation, or any other potential environmental hazards.

7.0 VAPOR ENCROACHMENT CONDITIONS
Partner conducted a limited non-intrusive vapor screening on the subject property to identify, to the extent feasible, the potential for vapor encroachment conditions (VECs) in connection with the subject property.

This included consideration of chemicals of concern (COC) that may migrate as vapors into the subsurface of the subject property as a result of contaminated soil and groundwater on or near the property.

This screening utilized readily available data sources previously discussed in this Phase I ESA that includes:
• the physical setting of the subject property (Section 2.4), • standard historical sources for the subject property, adjoining, and surrounding area (Section 3.0), • known or potentially contaminated sites as identified from information from regulatory agencies and sites on Federal, State, tribal and local databases (Section 4.0), and • information from the site reconnaissance (Section 6.0) of the subject property and observations of the surrounding properties.

The results of our data collection, reconnaissance, and analysis are tabulated below:

Potential for Vapor Encroachment to Impact the Subject Property Area of Concern Likely or Known VEC to Subject Property Subject Property Existing Operations or
Conditions
None identified that impact the subject property.

Historical Uses of the Subject Property As discussed in Sections 4.1.3 and 5.2.6, a known VEC was identified at Parcel A Building 29 (795 H Street).

Adjoining Property Operations or Existing
Conditions
None identified that impact the subject property.

Historical Uses of Adjoining Properties or
Nearby Properties
None identified that impact the subject property.

Regulatory Review of sites identified on
Federal, State, tribal and Local
Environmental Databases which were

None identified that impact the subject property.

As discussed in Section 4.1.3 and 5.2.6, recent 2021 soil vapor data collected within Buildings 99 and 100 did not indicate a need for additional assessment or vapor mitigation. According to the HHRA, VOCs in soil vapor beneath Building 29 will be managed by installing a sub-slab depressurization system (SSDS) and implementing a Risk Management Plan (RMP). Additional soil vapor investigation is not warranted at this time.

RE: CITY DIRECTORY RESEARCH
795 H Street, 390, 368, 360, and 364 Bay Boulevard
CHULA VISTA,CA 91910
Thank you for contacting ERIS for an City Directory Search for the site described above. Our staff has conducted a reverse listing City Directory search to determine prior occupants of the subject site and adjacent properties. We have provided the nearest addresses(s) when adjacent addresses are not listed. If we have searched a range of addresses, all addresses in that range found in the Directory are included.

Note: Reverse Listing Directories generally are focused on more highly developed areas. Newly developed areas may be covered in the more recent years, but the older directories will tend to cover only the "central" parts of the city. To complete the search, we have either utilized the ACPL, Library of Congress, State Archives, and/or a regional library or history center as well as multiple digitized directories. These do not claim to be a complete collection of all reverse listing city directories produced.

ERIS has made every effort to provide accurate and complete information but shall not be held liable for missing, incomplete or inaccurate information. To complete this search we used the general range(s) below to search for relevant findings. If you believe there are additional addresses or streets that require searching please contact us at 866-517-5204.

Search Criteria:
300-500 of Bay Blvd
750-860 of G St
700-END of H St
750-END of Lagoon Dr
Search Notes:

Lagoon Dr is also known as F St.

Dear Well Permit Clerk:

On behalf of Rohr, Inc., Haley & Aldrich, Inc., is pleased to provide this boring completion report to the County of San Diego Department of Environmental Health (DEH) for soil borings advanced to the groundwater level on the above‐referenced parcels in Chula Vista, California (Figures 1 and 2). The borings were drilled under well permit LMWP‐002368 approved by the DEH on 17 June 2016.

The borings were drilled by National EWP, Inc., a C‐57 licensed drilling company located in Montclair, California, using a direct‐push sampling device (GeoprobeTM). Boring logs with the required information as described in Site Assessment and Mitigation (SAM) are provided in Appendix A. Laboratory analytical results and chain of custody forms are provided in Appendix B.

At the completion of groundwater sampling, each boring was backfilled with granular bentonite, hydrated during placement and capped with either concrete or asphalt to match the existing grade. The table below provides a summary of the volume of materials used to backfill the borings.

Condition Upon Receipt:

Samples were received under Chain-of-Custody (COC) on 06/27/16. They were assigned to Work Order 16-06-1934.

Unless otherwise noted on the Sample Receiving forms all samples were received in good condition and within the recommended EPA temperature criteria for the methods noted on the COC. The COC and Sample Receiving Documents are integral elements of the analytical report and are presented at the back of the report.

Holding Times:

All samples were analyzed within prescribed holding times (HT) and/or in accordance with the Calscience Sample Acceptance Policy unless otherwise noted in the analytical report and/or comprehensive case narrative, if required.

Any parameter identified in 40CFR Part 136.3 Table II that is designated as "analyze immediately" with a holding time of <= 15 minutes (40CFR-136.3 Table II, footnote 4), is considered a "field" test and the reported results will be qualified as being received outside of the stated holding time unless received at the laboratory within 15 minutes of the collection time.

Quality Control:

All quality control parameters (QC) were within established control limits except where noted in the QC summary forms or described further within this report.

Subcontractor Information:

Unless otherwise noted below (or on the subcontract form), no samples were subcontracted.

Additional Comments:

Air - Sorbent-extracted air methods (EPA TO-4A, EPA TO-10, EPA TO-13A, EPA TO-17): Analytical results are converted from mass/sample basis to mass/volume basis using client-supplied air volumes.

Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not corrected for % moisture. All QC results are always reported on a wet weight basis.
