INTRODUCTION

URS Corporation (URS) has prepared this Surface Containment and Soil Management Plan (SMP) as part of the Remedial Action Plan (RAP) for the Former Kast Property (Site) in Carson, California on behalf of Equilon Enterprises LLC, doing business as Shell Oil Products US (Shell or SOPUS). The SMP is submitted in accordance with Cleanup and Abatement Order (CAO) No. R4 -2011 -0046 issued to Shell by the California Regional Water Quality Control Board - Los Angeles Region (RWQCB or Regional Board) on March 11, 2011 and the RWQCB's letter dated January 23, 2014 directing Shell to submit this RAP and Human Health Risk Assessment for cleanup of the Carousel Tract pursuant to California Water Code Section 13304.

The Regional Board is the lead Regulatory Agency for this project; however, the protocols presented ill this SMP are intended to apply to all parties involved in soil disturbance activities at the Site (e.g., excavation, landscaping, utility installation), including the City of Carson, County of Los Angeles Department of Public Works, local utility providers, contractors, and residents.

OBJECTIVE

This SMP provides the detailed approach to mitigate potential residential, construction, or utility worker exposure to soils that do not meet Remedial Action Objectives (RAOs) that may remain at the Site following implementation of the excavation remedy outlined in the RAP and forthcoming Remedial Design Implementation Plan (RDIP). For the purposes of this SMP, these soils will be referred to herein as "residual soils." The SMP details the long -term approach to address potential residual soils should the need arise to disturb these soils in the future. Residual soils may be present at depths below the depth of excavation, as well as in areas not excavated such as beneath homes, City sidewalks and streets.

BACKGROUND

Remediation of soil, soil vapor, and groundwater is required in portions of the Site to meet RAOs, as approved by the Regional Board. In accordance with the CAO, this SMP specifies on -going monitoring requirements for residual soils that will remain in place after remedial excavation. The SMP summarizes protocols for containment, monitoring, and management of such residual soils. This SMP is designed to be used in conjunction with existing administrative controls (e.g., City of Carson and Los Angeles County Codes regarding construction, grading, landscaping, and excavation and encroachment permits).

Site -related constituents of concern (COCs, those COCs associated with the historic use of the Site as an oil storage facility) consist of petroleum hydrocarbon- derived constituents and some metals. In addition, other chemicals have been detected in Site soils that are unrelated to the former Site use as an oil storage facility and are referred to as non- Site -related COCs.

Proposed remedial actions include excavation to 3 feet bgs in open areas and areas covered by residential hardscape, including residential planters, walkways, and uncovered patios at properties where risk estimates are above regulatory thresholds or may pose a concern for the potential leaching to groundwater pathway. Soil will not be excavated from properties from areas beneath homes, City sidewalks and streets. Excavated areas will be backfilled with clean imported soils and landscaping/hardscaping will be restored to like conditions. The backfilled clean soil and landscaping will provide a protective barrier to minimize the potential for exposure to soils below the depth of excavation. Soils below a depth of 3 feet and soils beneath surface containment features will be addressed through a soil vapor extraction (SVE) and bioventing system that will include installation of SVE /bioventing wells both in City streets and on residential properties where RAOs are not met based on existing conditions.

This Soil Containment and Soil Management Plan outlines procedures so that residents or construction/utility workers are not inadvertently exposed to soils that exceed the RAOs for the Site.

SURFACE CONTAINMENT

Physical barriers (e.g., presence of clean soil to a depth of 3 feet, hardscape, or structures) will serve to contain and /or prevent exposure to underlying impacted soils on a property and will restrict access and exposure to deeper soils. In areas where impacted soils will be excavated to 3 feet bgs, the certified clean imported soil backfill will serve as a soil barrier restricting exposure to underlying soils. Additionally, Site soils that meet RAOs will provide surface containment preventing contact with underlying residual soils. Where soils are not removed as part of the remedial excavation, the existing cover (consisting of concrete foundations and floor slabs of houses, garages, City sidewalks, street pavement, etc.) will provide a protective barrier to minimize the potential for exposure to impacted soil below. Site features, such as homes, garages, City sidewalks, and roads are considered part of the protective barrier.

MANAGEMENT OF RESIDUAL SOILS CONTAINING SITE COCS ABOVE SSCGS

Following remedial excavation, residual soils may remain below 3 feet bgs and beneath homes, garages, streets and City sidewalks. The potential for contact with these residual soils will be mitigated by the surface containment features described above, except in limited instances where excavation deeper than 3 feet may be necessary. Because City Code requires permits for excavations deeper than 3 feet, there is an administrative control already in place to restrict potential contact with these deeper soils (i.e., a permit requirement). This administrative control and notification mechanism is further discussed below.

Based on the distributions of COCs on each property (e.g., Figures 3 -3 through 3 -8 and Appendix B of this RAP), Shell will have a means to identify soils remaining after remedial excavation and remedial system installation that do not meet RAOs. This will provide a sufficient summary of the residual soils remaining at the Site to allow any entity performing future excavations at the Site to anticipate the environmental conditions they may encounter. It is anticipated that SVE /bioventing will reduce levels in residual soils to meet RAOs within approximately 30 years (see Section 8.2.4 of the RAP).

Administrative Controls In their January 23, 2014 letter, RWQCB states that excavation to a depth requiring a grading permit under Los Angeles County building code "is supportive of unrestricted residential use because institutional controls are already in place..." (RWQCB, 2014a). RWQCB notes that in the Carousel Tract, the Los Angeles County building code is administered by the City of Carson. RWQCB states as follows: "Because the City of Carson must be notified and approve excavations below five feet, the City could readily inform residents and workers of other appropriate precautions necessary for excavations below five feet through existing administrative processes." The LA County building code, therefore, acts as an applicable or relevant and appropriate requirement (ARAR) for excavations deeper than five feet at the Site.

While the statements above refer to the County requirement of Grading Permits for excavations 5

feet or deeper, the City of Carson has amended L.A. County building code Section 7003.1 to require a Grading Permit for excavations 3 feet or deeper. City of Carson Building Code Section 8105 (amending the L.A. County Building Code) states that:

A Grading Permit shall not be required for:

L An excavation which (a) is less than three (3) feet in depth below natural grade, or (b) does not create a cut slope greater than three (3) feet in height and steeper than one and one -half (1 -1/2) horizontal to one (1) vertical.

2. A fill not intended to support structures and which does not obstruct a drainage course if such fill is placed on natural grade that has a slope not steeper than three (3) horizontal to one (1) vertical and (a) is less than one (1) foot in depth at its deepest point, measured vertically upward from natural grade to the surface of the fill, or (b) does not exceed twenty (20) cubic yards on any one (1) lot.

Thus, the City of Carson has amended L.A. County building code Section 7003.1 to require a Grading Permit for excavations deeper than 3 feet, and these existing institutional controls support the 3 -foot soil excavation remedy. Because the City must be notified and approve excavations deeper than 3 feet (City of Carson Building Code §8105 amending Los Angeles County Building Code §7003.1), the City could readily inform residents and workers of appropriate precautions necessary for excavations below 3 feet through an existing administrative processes, and also notify Shell that monitoring and disposal of residual soils may be required.

Shell intends to coordinate with the City of Carson to establish a process through existing building and grading permit reviews, General Plan overlay or footnote, area plan, or similar process, to ensure that if a property owner plans to conduct activities involving excavations greater than 3 feet deep (such as building renovation, installation of a pool or deeper landscape alterations), Shell is notified so that it can arrange for sampling and proper handling of impacted soils that may be present. It is expected that, based on the City permitting requirements, redistribution of deep soils to the surface at

The LA County building code, therefore, acts as an applicable or relevant and appropriate requirement (ARAR) for excavations deeper than five feet at the Site.

While the statements above refer to the County requirement of Grading Permits for excavations 5

feet or deeper, the City of Carson has amended L.A. County building code Section 7003.1 to require a Grading Permit for excavations 3 feet or deeper. City of Carson Building Code Section 8105 (amending the L.A. County Building Code) states that:

A Grading Permit shall not be required for:

1. An excavation which (a) is less than three (3) feet in depth below natural grade, or (b) does not create a cut slope greater than three (3) feet in height and steeper than one and one -half (1 -1/2) horizontal to one (1) vertical.

2. A fill not intended to support structures and which does not obstruct a drainage course if such fill is placed on natural grade that has a slope not steeper than three (3) horizontal to one (1) vertical and (a) is less than one (1) foot in depth at its deepest point, measured vertically upward from natural grade to the surface of the fill, or (b) does not exceed twenty (20) cubic yards on any one (1) lot.

Thus, the City of Carson has amended L.A. County building code Section 7003.1 to require a Grading Permit for excavations deeper than 3 feet, and these existing institutional controls support the 3 -foot soil excavation remedy. Because the City must be notified and approve excavations deeper than 3 feet (City of Carson Building Code §8105 amending Los Angeles County Building Code §7003.1), the City could readily inform residents and workers of appropriate precautions necessary for excavations below 3 feet through an existing administrative processes, and also notify Shell that monitoring and disposal of residual soils may be required.

Shell intends to coordinate with the City of Carson to establish a process through existing building and grading permit reviews, General Plan overlay or footnote, area plan, or similar process, to ensure that if a property owner plans to conduct activities involving excavations greater than 3 feet deep (such as building renovation, installation of a pool or deeper landscape alterations), Shell is notified so that it can arrange for sampling and proper handling of impacted soils that may be present. It is expected that, based on the City permitting requirements, redistribution of deep soils to the surface at

these properties will not be permitted. An example of such an enhancement is in use at the Del Amo Soil and NAPL OU site.'

Because an institutional control is already in place in the City of Carson requiring grading permits in order to excavate at depths below 3 feet, these requirements are not expected to interfere with the unrestricted resident's use and enjoyment of their property.

Activities that may disturb impacted soil (e.g., excavation, grading, trenching, filling, earth movement, or removal of soil) below a depth of 3 feet require advance notification to the City of Carson. A mechanism will be established with the City for notification to be made to the Regional Board and Shell. The property owner(s) would be directed to provide advance notice of plans to conduct construction activities that may encounter residual impacted soil. If advance notice is impractical, such as during urgent or emergency utility work, notice should be provided as soon as practical after the work begins, so that Shell may arrange for sampling and proper handling of impacted soils that may be present.

Additionally, Shell's consultants are and will continue to be set up within the Underground Service Alert (USA) one -call system to receive notification of planned excavation work in the Carousel Tract. Upon notification of planned excavations, Shell or its representatives will coordinate with the entity that contacted USA (whether the homeowner or their representative, a homeowner's contractor, or utility company such as Cal- Water, Southern California Gas Company, or AT &T) to provide monitoring, management, handling and proper disposal of residual soils during excavation activities.

At the Del Amo Soil and NAPL OU site, the site remedy includes multiple layers of institutional controls (ICs) used in conjunction to protect site workers and the public from potential exposure to site contaminants. One of the layers of the ICs is called the "Permit Review IC ", which is currently active as a pilot program. For this Permit Review IC, the responsible parties (including Shell), USEPA, and DTSC worked together with the City of Los Angeles to place "flags" in the Los Angeles Department of Planning's Zoning Information and Map Access System (ZIMAS) database for the parcels that make up the Del Amo site. Flags alert City staff and applicants of special conditions or restrictions that apply to a specific parcel. These flags provide information and instructions to City employees and permit applicants who propose development in identified locations that require grading/excavation or building permits. The flag informs the user that the parcel's location requires contact with EPA's project team for an environmental review. As building permit applications are reviewed by the City of Los Angeles Building and Safety Department, applicants are be referred to EPA's Environmental Review Team (ERT) to review construction plans and determine whether contaminated soil or groundwater would be encountered. The ERT is currently composed of EPA, DTSC, along with the responsible parties.

With this IC pilot program, the responsible parties serve as the point of contact for permit applicants. The responsible parties conduct an initial review by obtaining information from the applicant regarding the nature of the proposed construction project, proposed land use, and locations and depths of excavations. If the proposed project involves applicable soil penetration, EPA issues a letter to the applicant that outlines specifies actions to be taken prior to or during the construction process that are necessary to protect human health and the environment, or that states that the project can proceed without further evaluation.

Monitoring

A number of types of monitoring may be performed to support excavation activities, depending on the volume and extent of excavation. Appropriate monitoring for dust, odor, and vapors will be conducted. Where required, Shell will offer to perform monitoring if not otherwise being performed by party doing the work. At a minimum, real -time monitoring of the work area and excavations will be conducted using a photoionization detector (PID) during excavation operations. Monitoring may also be conducted with a flame -ionization detector (FID) for methane in the parts per million by volume (ppmv) range and a four -gas meter for methane in the percent level, oxygen, carbon dioxide, and hydrogen sulfide. Monitoring for odors may also be conducted based on worker perception, at the downwind property boundary of the residential property where excavation is occurring.

To mitigate offsite dust migration and resultant impacts to neighboring properties, dust monitoring will be conducted for large excavations. If visible dust is encountered, periodic watering of the active excavation areas will be recommended throughout the excavation and backfill activities. In addition to dust suppression efforts, odor suppressants will be recommended to mitigate offsite migration of odors from the work area.

Soils Management

As discussed above, notification through participation in the USA system or City of Carson permit requirements will allow Shell's representatives to collect appropriate samples and arrange for disposal of soil generated from utility work, if appropriate. If excavation of the soil is necessary for residential or utility provider construction activities, it is likely that impacted soil will not be suitable for re -use. Shell will, if requested by the property owner or utility service provider, arrange for the removal, transportation, and offsite disposal by a qualified waste contractor of residual soil. If potentially impacted soil is observed during urgent or emergency construction activities (e.g., a gas line repair), and an authorized representative is not onsite, Shell should be notified as early as possible to allow the material to be profiled and properly disposed. If Site soils are being excavated on an urgent basis, the property owner or contractor should ensure that potentially affected soil is segregated and stockpiled to allow for proper soil profiling and management.

After receiving notification that potentially impacted soil will be encountered during the course of construction activities, Shell will arrange for a contractor to collect samples of the soil (either in situ or from a segregated stockpile) for profiling purposes if an updated waste profile is needed.

To the extent possible, impacted soil will be direct loaded into approved waste containers for transport to the appropriate recycling or disposal facility. With advance notice, Shell will provide suitable containers based on the nature of the excavation work being conducted. In the event that it is necessary to temporarily stockpile soil onsite before loading, soils should be placed upon plastic sheeting and covered with plastic until they can be loaded into approved waste containers to be provided by Shell.

Excavated impacted soil will be transported offsite to appropriately licensed recycling/disposal facilities by a state -licensed waste hauler for appropriate recycling or disposal. To the extent possible, soils will be pre -profiled, and approval will be obtained from the recycling/disposal facilities before excavation activities begin. All documentation pertaining to waste disposal profiles and waste disposal acceptance will be in place prior to any offsite shipments of waste.

Program Eligibility Residing owners or tenants of a residential property that qualifies for temporary living arrangements (as determined by Shell or its consultants /contractors as set forth above) due to remediation- related excavation activities are eligible for the Program.

It is a requirement of the Program that the resident sign a "Use of Home and Acknowledgement of Payment to Occupants" form in order to receive program benefits. Please see Attachment A - "Use of Property and Acknowledgement of Payment of Occupants."

Planned Remediation Activities

Overview

As described in the RAP, Shell intends to conduct the following multi -media remedial actions for the Site:.

Excavation of shallow soils on impacted residential properties based on the findings of the Human Health Risk Assessment and protection of groundwater criteria, as specified in the RAP.

Soil vapor extraction (SVE) to address volatile petroleum hydrocarbons, volatile organic compounds (VOCs) and methane in soil vapor where appropriate and to promote degradation of residual hydrocarbons in deeper soil following shallow soil excavation. SVE wells will be installed in City streets and on residential properties, as appropriate.

Bioventing to induce oxygen levels in subsurface soils to promote microbial activity and degrade longer -chain petroleum hydrocarbons. Bioventing will work in conjunction with SVE.

Sub -slab mitigation at a limited number of properties where sub -slab soil vapor concentrations exceed site -specific cleanup goal values.

Continued recovery of crude oil floating on the water table from two wells located on Marbella Avenue.

Continued groundwater monitoring to support monitored natural attenuation for groundwater. Additional groundwater remedial actions may be undertaken in the future, but it not expected that these actions will affect residences.

Of these activities, excavation of shallow soils is the only activity anticipated to require temporary relocation of residents of the affected properties. Based on findings of the Human Health Risk Assessment, Shell will excavate shallow soils at approximately 183 residential properties to a depth of 3 feet below existing grade where the presence of soil impacts results in estimates of incremental lifetime cancer risk and non- cancer hazard that are above regulatory thresholds or may pose a concern for the potential leaching to groundwater pathway.

Soils will be excavated from both landscaped areas and areas currently covered by hardscape, including walkways, driveways, and patio areas. Hardscape and landscaping will be removed during the initial stage of excavation and restored to like conditions following completion of excavation. Shell also anticipates that it may be necessary to remove fences and block walls between yards and ornamental or partitioning walls on individual properties, as the depth of excavation will exceed footing depths. If possible, fences and walls will be protected in place and not removed; however, they will be removed and restored if necessary. As with other hardscape, fences and walls will be restored following completion of excavation along with restoration of landscaping. Exceptions to excavation beneath hardscape include patios covered by structures and roofs and pool decking surrounding swimming pools. These hardscape areas will not be excavated to avoid structural demolition and potential damage to swimming pools and appurtenant equipment.

Following approval of the RAP, a Site -wide Remedial Design and Implementation Plan (RDIP) will be prepared along with a Property Specific Remediation Plan (PSRP) for each property that requires remedial action. As part of PSRP preparation, Shell contractors will meet with homeowners and /or residents, and their legal representatives to obtain necessary information for relocation during remedial implementation and to discuss hardscape and landscape restoration.

Remedial excavation is anticipated to proceed in phases, if possible with each phase of work including approximately eight contiguous properties. Each phase will include homes on both sides of a city block (e.g., the east side of Marbella and west side of Neptune Avenues). This approach will be used so that if it is necessary to remove back fences or block walls, the fences can be removed one time and excavation conducted in both yards before the fences are restored.

Preliminarily, it is estimated that excavation and backfill will take approximately 3 weeks per property with site restoration taking approximately an additional 3 to 4 weeks. Approximately seven weeks would be needed to complete a phase of eight properties. Thus, residents may be relocated for a period of approximately seven weeks, with potential for shorter or longer durations. Following backfill and utility and hardscape restoration, residents would move back into their homes during landscape restoration and fence /block wall construction, or, at their option, wait to return until after the landscape restoration work is completed.

Temporary Living Assistance

Overview

The goal of the Program is to provide eligible households with financial assistance toward the temporary living expenses that participants may incur due to temporary relocation during remediation activities. In addition, if desired, assistance with temporary living arrangements may be provided.

How the Program Assistance Payment is Established

At least two weeks prior to the relocation date, a meeting will be held with the residents to provide information about financial assistance to facilitate relocation, including relocation or boarding of pets and assistance with transportation, if needed. Residents will be asked for general information about persons living in the home, such as the number of adults and children and the ages of the children.

Assistance with Temporary Living Arrangements

Residents will have the option to stay at a hotel of their choice and make their own arrangements subject to the daily payment amounts provided below. If requested, residents may choose to stay at a hotel arranged by and direct billed to Cartus. Available hotels for direct billing include:

Marriott Residence Inn Torrance, 3701 Torrance Boulevard, Torrance, California;

Marriott Residence Inn Manhattan Beach, 1700 North Sepulveda Boulevard, Manhattan Beach, California;

Marriott Courtyard Torrance, 2633 Sepulveda Boulevard, Torrance, California;

Marriott Residence Inn Downtown Long Beach, 600 Queensway Drive, Long Beach, California; and

Marriott Residence Inn Long Beach, 4111 East Willow Street, Long Beach, California

In either instance, Shell will pay any pet fees charged by the hotel.

If requested, Cartus can make the initial reservations and will provide contact information at the hotel in case any changes need to be made. In addition, direct billing can be set up for the room, pet fees, and tax. However, all other expenses (meals, etc.) shall be paid directly by the participating residents. Meals and other miscellaneous assistance based on the family profile will be provided in the payment amount. Any damage to hotel rooms, furnishings or other property during relocation periods will be the responsibility of the relocated residents.

Program Payment

The Program will provide eligible participants with assistance towards the temporary living expenses such as lodging and meals that may be incurred as a result of the remediation being completed at their home. The Program payment will be calculated by Cartus and will be communicated after the interview conducted as part of the RDIP and PSRP process.

Payment will be provided in the form of funds loaded onto one debit card per property. As noted above, the resident will need to sign a "Use of Property and Acknowledgement of Páyment to Occupants" form in order to receive the payment. Please see Attachment A for further information.

Shell will provide relocated residents a daily meal allowance of $71 per day per adult, and $36 per day per child. These amounts are based on the 2014 Federal per diem allowance for the Los Angeles area (http: / /www.gsa.gov /portal /category/100120). For the purposes of meal allowance calculations, a child is considered a person 12 years of age or younger. If a resident chooses to make their own hotel arrangements, the hotel allowance is $165 per night per room, based on 2 people per room. This amount is higher than the 2014 Federal per diem allowance for the area. Additionally, an inconvenience allowance will also be provided.

Shell will provide relocated residents a daily meal allowance of $71 per day per adult, and $36 per day per child. These amounts are based on the 2014 Federal per diem allowance for the Los Angeles area (http: / /www.gsa.gov /portal /category/100120). For the purposes of meal allowance calculations, a child is considered a person 12 years of age or younger. If a resident chooses to make their own hotel arrangements, the hotel allowance is $165 per night per room, based on 2 people per room. This amount is higher than the 2014 Federal per diem allowance for the area. Additionally, an inconvenience allowance will also be provided.
