SECTION 1.0 INTRODUCTION

1.1 Defense Logistics Agency (DLA) Mission

As stated in the Performance Work Statement (PWS).

1.2 General Description

As stated in the PWS.

1.3 Facility Locations

The former Defense Fuel Support Point (DFSP) Norwalk is located at 15306 Norwalk Boulevard, Norwalk, California (CA). An eight-inch diameter pipeline, known as the El Toro Pipeline, was used to transport jet propellant (JP)-5 fuel from DFSP Norwalk to the former Marine Corps Air Station (MCAS) El Toro. The El Toro Pipeline Release Site is located at the intersection of Newport Avenue and Old Irvine Boulevard in Tustin, CA. The DFSP Norwalk and El Toro Pipeline Release Site are not geographically contiguous but are contractually managed together.

The lead regulatory agency for DFSP Norwalk is the Los Angeles Regional Water Quality Control Board (LA RWQCB). The lead regulatory agency for the El Toro Pipeline Release Site is the Santa Ana RWQCB (SA RWQCB).

1.4 Scope of Environmental Services

As stated in the PWS.

SECTION 2.0 FACILITY-SPECIFIC INFORMATION

2.1 Facility Information

2.1.1 DFSP Norwalk

The approximately 51-acre DFSP Norwalk was formerly used to store and transfer JP-4, JP-5, and JP-8. The facility was acquired by the United States Air Force (USAF) in 1951.

Site operational responsibility transferred to the Defense Logistics Agency (DLA) in 1968, but ownership was retained by the USAF.

The DLA operational area included approximately 47 acres. Prior to decommissioning in 1999, the facility consisted of 12 aboveground storage tanks (ASTs), truck loading racks, and associated underground and aboveground piping and facilities. Historical releases and fuel leaks occurred from the ASTs, truck loading racks, and connecting pipeline systems throughout the operational history of the Site. By the early 1990s, jet fuel transfer via tanker trucks was no longer routinely practiced. Instead, a 10-inch, Government-owned multi-product pipeline carried fuel from DFSP San Pedro to the Site, and an eight-inch pipeline carried fuel from the Site to the former MCAS El Toro. To date, over 10,000 gallons of Light Non-Aqueous Phase Liquids (LNAPL) have been

DFSP Norwalk PWS actively recovered and over three million pounds of diesel and gasoline range organics have been removed and/or treated.

Aboveground storage tanks (ASTs) and associated aboveground piping were removed in 2011 and 2012. Fifteen acres comprising the eastern portion of the Site were transferred to the City of Norwalk, California in August 2018. The western portion of the Site will be transferred for disposal through the General Services Administration (GSA). The transfer date for the western portion of the Site is undetermined and dependent upon completion of additional remedial action, receipt of desired LA RWQCB no further action (NFA) determination, and completion of the GSA Federal property disposal process. The LA RWQCB has indicated that per- and polyfluoroalkyl substances (PFAS) in site soil and groundwater need to be addressed before it will issue a Site NFA determination.

Kinder Morgan Energy Partners (KMEP) formerly operated a fuel pumping and distribution system on two acres along the central, southern property boundary. The pumping and distribution system have been removed, but three underground fuel transmission pipelines for gasoline, diesel, and jet fuel remain in operation along the southern and eastern boundaries of the Site. Known releases of automotive gasoline and other fuels have occurred at the KMEP lease area and have been detailed in reports prepared by KMEP. KMEP investigated past releases and has installed and operated soil vapor extraction (SVE) wells and groundwater remediation wells. KMEP is responsible for the remediation of shallow soil in the south-central portion of the Site.

Current and anticipated land use for the Site is commercial/industrial. There is interest in redeveloping the Site for recreational use as a park to possibly include a stage area, athletic fields (e.g., soccer, softball, baseball), concessions, and parking. Contractor assistance to develop deed restrictions, land use control plan, and/or memorandum of agreement (MOA) with third-party landowner(s) and appropriate stakeholders is anticipated.

The DLA has installed and continues to operate various remediation systems at the Site to address contamination in deeper soil and groundwater. These include a groundwater extraction and treatment system (GWETS), soil vapor extraction (SVE) system using both vertical and horizontal vapor extraction wells, biosparging system, and active and passive techniques to recover LNAPL.

Eastern Parcel of Site Shallow soil remediation in the 15-acre Eastern Parcel was completed in 2017 through the excavation and on-site treatment of approximately 100,000 tons of contaminated vadose zone soils. In April 2018, the LA RWQCB granted a conditional No Further Action (NFA) determination for shallow soil (upper 10 feet [ft]) for the Eastern Parcel.

The conditional NFA determination required recordation of a deed restriction limiting site use to commercial/industrial applications, and relayed responsibility to DLA and KMEP to address remaining soil and groundwater impact. In August 2018, the Eastern Parcel was disposed to the City of Norwalk for the Holifield Park extension, and the deed restriction was recorded by the city.

DFSP Norwalk PWS

The DLA has expanded the remediation system into the Eastern Parcel through installation of additional horizontal and air sparge/SVE wells to remediate deeper soil and groundwater. An access agreement exists with City of Norwalk but will expire in December 2026. An annual access fee is assessed by the City of Norwalk.

The City of Norwalk has initiated redevelopment preliminary planning and design.

Contractor oversight and design input will be requested, as needed, to protect DLA property (i.e., remediation system mechanical, monitoring, and ancillary components) that may be compromised by the City’s redevelopment plans or actions.

Western Parcel of Site Shallow soil remediation activities that included excavation and ex-situ bioremediation of approximately 47,771 cubic yards (CY) of soil were conducted from April 2015 until March 2017 in the 36-acre Western Parcel. A Human Health Risk Assessment (HHRA) was also performed to evaluate risks from shallow soil and soil gas. Findings of the HHRA were reported in 2018 and supported a request for shallow soil NFA for industrial/commercial exposure scenarios. In response to regulatory agency requests, additional soil gas surveys were completed, and additional receptor exposure scenarios evaluated. Detections of tetrachloroethylene (PCE), which had not been previously identified as a Site potential contaminant of concern, and PFAS, were also evaluated. The revised HHRA found that chemicals of potential concern in shallow soil (upper 10 ft.), soil gas, and groundwater do not pose an unacceptable human health risk for the additional hypothetical construction/trench worker and hypothetical resident commercial worker exposure scenarios that were evaluated, except in soil vapor at the western property boundary and a “carve out” area in the southeast portion of the Site.

Contaminants of concern in soil vapor along the western property boundary are attributed to an offsite source and will be addressed by other parties. Further assessment of risk posed by soil vapor in the “carve out” area is pending final review and approval by the California Office of Environmental Health Hazard Assessment (OEHHA). The revised HHRA reported the presence of PFAS in shallow soil does not contribute significantly to incremental risks.

The LA RWQCB verbally concurred that input to support shallow soil closure for the Western Parcel has been provided but requested that land use controls be developed. The RWQCB has relayed that the potential presence of PFAS in deeper soil and groundwater will delay issuance of Site NFA. An investigation to determine the extent of PFAS in soil and groundwater is scheduled to be completed in late 2024. Follow-on response actions for PFAS, if warranted based on risk evaluation or assessment, and as allowed by current DOD policy, will be addressed by this contract. Contractor assistance to develop land use controls and/or a memorandum of agreement (MOA) between DLA and third-party owners, if required, is in place and extends through October 2024. It is anticipated that this support will be required past October 2024 pending the findings of the PFAS investigation.

It is desired that the remedial response process be complete prior to disposal of the Western Parcel. If the Western Parcel is transferred to a third party prior to completion of remedial response, an access agreement will be required, access fee may be imposed, and

DFSP Norwalk PWS contractual support will be needed for oversight and design input to protect DLA property (i.e., remediation system mechanical, monitoring, and ancillary components) that may be compromised by third party redevelopment and/or access restrictions.

Sitewide Groundwater extraction continues, and treatment systems that were shut down during shallow soil remediation activities, e.g., biosparge and SVE, have been recommissioned and/or expanded and are operational. Thermal treatment and LNAPL removal are also ongoing. A Workplan was prepared in 2022 to support evaluation of the viability of Natural Source Zone Depletion (NSZD) as a long-term Site remedy.

During recent operational quarters, as little as 20 gallons of LNAPL have been gauged and removed by bailing, skimming, use of absorbent socks, or other method; and the LNAPL product recovery system was offline due to low LNAPL yields. The measured LNAPL thickness ranged from zero to less than one-half foot, with a maximum of 3.55 feet recorded in one well during a recent quarterly period. As supported by dissolved groundwater analytical data for off-site wells, previous aquifer pump testing, and groundwater capture zone analysis, the GWETS and natural attenuation appear to have successfully prevented further migration of impacted groundwater offsite; and a significant portion of impacted groundwater under the adjacent Holifield Park to the east has been treated. Groundwater extraction (GWE) in the central area from wells GMW-31 and GW-14R, and in the eastern area from well GW-16, will continue to assist with containment until further evaluation of NSZD is complete.

It is estimated that the hydrocarbon mass extraction rate will become asymptotic by roughly December 2023 and that the existing treatment systems will be conditionally shut down beginning in April 2024. During the shutdown period, additional monitoring and data gathering will occur over a six-month period to support evaluation of NSZD viability. A NSZD study report is scheduled to be finalized in December 2024. Transition from active remediation to NSZD/monitored natural attenuation (MNA) is tentatively planned at the end of 2025. The SVE, biosparge, LNAPL recovery, and groundwater extraction systems may be re-started and operated for a six- to 12-month period between October 2024 to October 2025, if the NSZD study data identifies benefit from additional focused treatment. A soil gas survey is scheduled in fiscal year (FY) 2026 as required by the regulatory agency. Remedial action completion is estimated to occur in 2027 and Site closeout with LA RWQCB concurrence in 2028. Separate but concurrent response to address PFAS will be required under this contract.

Cleanup Levels Soil cleanup goals are designed to be protective of groundwater. Higher concentrations of hydrocarbons are allowed up to a depth of 10 ft. below ground surface (bgs), and lower limits are established below 10 ft. bgs closer to groundwater. Soil cleanup goals are presented in LA RWQCB letter, Approval of Modification to the Soil Cleanup Goals, SCP No. 0286A, Site ID No. 16638, July 16, 2015.

DFSP Norwalk PWS

Data collected as part of the NSZD baseline monitoring and MNA evaluations will be used to develop petroleum hydrocarbon cleanup goals for groundwater. It is anticipated that these efforts will be complete by December 2024.

Groundwater Monitoring Groundwater monitoring is conducted on a semi-annual basis jointly by the DLA and Santa Fe Pacific Pipeline L.P. (SFPP), an operating partnership of KMEP. Recent monitoring events have included measurement of water levels in over 170 wells, and collection of samples from over 120 wells. Upward of 10 wells have been dry during recent monitoring events. Exposition Aquifer wells that are included in the sampling and analysis plans for both DLA and SFPP are gauged more than once. Samples are not collected from wells that contain measurable free product. Methyl tertiary-butyl ether (MTBE) and various detergents have been detected in groundwater at DFSP Norwalk.

These constituents are not typical of DLA-capitalized fuel and are likely attributable to historic releases from non-DLA sources at or near the Site. An investigation to determine the extent of PFAS in soil and groundwater is scheduled to be completed in late 2024.

Follow-on response actions for PFAS, if warranted based on risk evaluation or assessment, and as allowed by current DOD policy, will be addressed by this contract.

Restoration documents for DFSP Norwalk are available on the California Water Resources Control Board GeoTracker data management system, accessible at:

GeoTracker (ca.gov) (https://geotracker.waterboards.ca.gov/). Records for DFSP Norwalk may be accessed using Site Global Identification (ID) number SLT43185183.

2.1.2 Tustin El Toro Pipeline Release Site

The El Toro Pipeline is an eight-inch diameter carbon steel pipeline that was constructed in 1956 and used to transport JP-5 fuel from the former DFSP Norwalk to the former MCAS El Toro. Between 1988 and 1990, approximately 500,000 to 750,000 gallons of JP-5 were released into the environment from the pipeline reportedly from a pipeline elbow joint located beneath the intersection of Newport Avenue and Old Irvine Boulevard in Tustin, CA. Damage to the pipeline is believed to have been originally caused by a backhoe during repair to another third-party operated line located directly above the El Toro Pipeline. The DOD did not immediately identify the cause of the release and noted reporting discrepancies until 1990. The El Toro Pipeline was repaired and continued to operate until 1999. In April 1999, the pipeline was removed from service, purged with nitrogen, and closed in place. The Site and vicinity have been redeveloped by third parties and are used primarily for commercial purposes including retail and office space (e.g., Walgreens and Plaza Lafayette properties).

Investigation of the JP-5 release began in 1989. Investigations completed in that timeframe identified that the impacted area consists of a floating product plume, a dissolved-phase hydrocarbon plume, and petroleum-contaminated vadose zone soil. Soil and groundwater analyses revealed the presence of TPH as JP-5; TPH as gasoline; methyl tert-butyl ether (MTBE); tert-butyl alcohol (TBA); benzene, toluene, ethylbenzene, and total xylenes (BTEX); and 1,2-Dichloroethane (1,2 DCA).

DFSP Norwalk PWS Facility Specific Appendix SPE603-25-R-0503 ATTACHMENT #2 https://geotracker.waterboards.ca.gov/

There are three private petroleum UST release sites on record in the nearby area. The presence of fuel oxygenates (i.e., MTBE and TBA) and fuel additives (i.e., 1,2 DCA) in soil and groundwater in the vicinity of the pipeline release are interpreted to be associated with past operation of the nearby petroleum USTs. Neither fuel oxygenates nor the observed fuel additives were historically used in JP-5 fuels and are not considered legacy constituents of DLA capitalized fuel. Media impacted by DLA capitalized fuel include soil and groundwater (dissolved-phase plume) for total petroleum hydrocarbons (TPH) as

JP-5.

Maximum product thickness of 23 feet has been recorded at well DP-01R. Although there are active potable water wells within 1,000 feet, the wells are screened greater than 150 feet below the contamination and are sampled regularly. (The wells are, however, located in a sensitive groundwater recharge area.) Tens of thousands of gallons of LNAPL have been removed from the release sites since 1992. The DLA currently performs LNAPL gauging and recovery as needed on a biweekly schedule, and groundwater monitoring and sampling on a semi-annual schedule.

A three-phase interim cleanup plan utilizing dual phase extraction (DPE) was developed to remove the remaining jet fuel and treat contaminated groundwater. Phase 1 is underway and consists of a DPE treatment system at the Plaza Lafayette property that includes an extraction well network, an SVE system equipped with a thermal oxidizer, and a GWETS. Extraction wells include four DPE wells and two monitoring wells, both connected to the GWETS and one of which is actively pumping. Phase 2 is planned at the Chevron/Walgreens property and will also include a DPE system. Implementation of Phase 2 is pending an access agreement. Phase 3 will address the contamination under Old Irvine Boulevard and Newport Avenue via an expansion of the Plaza Lafayette DPE system. Previous investigations have identified LNAPL residing in unsaturated soils, floating on the groundwater, and trapped in sediment below the current groundwater surface (approximately between 80 and 100 ft. bgs). Phase 3 is intended to significantly increase the recovery of released JP-5. Soil cleanup goals are presented in the Phase 3 Interim Remedial Action Plan (IRAP), Table 2 (Phase 3 Interim Remedial Action Plan, El Toro Pipeline Release Site, Newport Avenue and Old Irvine Boulevard, Tustin, California, April 2023).

Dual phase extraction (DPE) supports removal of LNAPL and impacted groundwater as well as vapor phase constituents from source-zone soils. Although planned as an interim remedy for the Site, it may also be a viable final remedy technology. A pilot study is currently underway to assess subsurface conditions and evaluate the efficacy of DPE as a final remedy technology for the Site.

Additional passive remediation such as NSZD may be necessary to achieve conditions for Site closure under the State Water Resources Control Board (SWRCB) Low Threat Underground Storage Tanks Case Closure Policy (LTCP; [SWRCB, 2012]).

Active remediation using the DPE system is anticipated to continue through mid-FY26.

This will include semi-annual groundwater monitoring and monthly free product recovery coinciding with the operation and maintenance of the DPE system. Six years of

DFSP Norwalk PWS semi-annual groundwater monitoring to confirm rebound has not occurred is anticipated from FY27 through FY32. If additional passive remediation is relied upon to achieve cleanup goals, the monitoring period will be extended to support an MNA approach. Site closeout is estimated to occur in FY38.

The Site closeout approach is sufficient to meet the needs of DLA and other stakeholders considering remediation complexity for the Site. The DLA may arrange a remedial systems evaluation and optimization study to be conducted by an independent third party.

Contractor will support and participate in the independent study. A task order may be issued for implementation of accepted recommendations from the independent study.
