Revised Soil and Groundwater Management Plan
880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 4 RMD ENVIRONMENTAL SOLUTIONS, INC. -2

4.1.2 Soil Categorization
Based on the field screening, excavated soil will be segregated into stockpiles in three categories:
• Background Soil: No visual and odor indicators, and PID measurements that are consistent with background levels. PID readings of up to 5 parts per million by volume (ppmv) will be considered background levels. These soils will be characterized for onsite reuse. • Interim Soil: No visual and odor indicators, and PID measurements between 5 ppmv and 50 ppmv. These soils will be characterized for onsite reuse. If initial findings indicate that this category does not meet onsite soil reuse criteria (see Section 4.2), these soils may be characterized for offsite disposal.
• Contaminated Soil: Staining and odor indicators present, and/or PID measurements of more than 50 ppmv2
. These soils will be further evaluated and are likely to be characterized for offsite disposal (see Section 4.3).

General stockpile management is described in Section 8.

4.1.3 De Minimis Soil
Soil produced during the following activities are considered de minimis:
• Trenching during utility line installation, and similar projects; and • Small excavations during landscaping, fence/sign post installation, and similar projects.

These soils will be field screened and reused to backfill the excavation from which they originated without sampling and laboratory analysis unless categorized as Contaminated Soil. Contaminated Soil and excess soil, if any, will be segregated and stockpiled based on field screening results.

4.2 Onsite Soil Reuse
As mentioned above, a vapor intrusion mitigation system is planned for installation beneath the new commercial building footprint. Other areas of the Site will be used for outdoor parking and loading. These conditions indicate that exposure pathways to COPCs in the subsurface will be managed or incomplete.
2 As defined by BAAQMD Regulation 8, Rule 40, Section 205, contaminated soil has an organic content exceeding 50 parts per million by weight (ppmw) as measured using an appropriate laboratory analysis or registers an organic concentration greater than 50 ppmv as measured at a distance of three inches from the surface of the soil with an organic vapor analyzer.

Revised Soil and Groundwater Management Plan
880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 4 RMD ENVIRONMENTAL SOLUTIONS, INC. -3
Based on field screening, de minimis soil may be reused to backfill the excavation of origination.

Background and interim soil stockpiles will be sampled to evaluate onsite reuse in general accordance with the DTSC Information Advisory Clean Imported Fill Material, dated October 2001 (Appendix E).

For onsite soil reuse, a limited set of laboratory analyses are planned:
• VOCs by USEPA Method 8260B (with collection by USEPA Method 5035).

For excavated and stockpiled import material, the following sampling frequency will be used:
• Up to 1,000 cubic yards – one sample per 250 cubic yards. • 1,000 to 5,000 cubic yards – 4 samples for the first 1,000 cubic yards plus one sample per each additional 500 cubic yards.
• Greater than 5,000 cubic yards – 12 samples for the first 5,000 cubic yards plus 1 sample per each additional 1,000 cubic yards.

The analytical results of the import soil samples will be compared to applicable screening criteria to evaluate whether the material is suitable for reuse at the Site. Applicable screening criteria will include DTSC soil SLs3 for direct exposure for commercial/industrial land use.

4.3 Response Measures for Discovery of Potentially Impacted Soil If soil exhibiting evidence of contamination (e.g., visual and odor indicators, and PID measurements of more than 50 ppmv), is encountered during ground disturbing activities, the General Contractor will cease ground disturbing activities in the area and delineate the area with barricades or fencing, stakes and plastic sheeting as appropriate, and signage to notify onsite workers and visitors of access restrictions. The General Contractor will notify the Property Owner and Environmental Consultant. Upon notification, the Environmental Consultant will implement and/or provide oversight for the response measures described in the following sections.

4.3.1 Preliminary Assessment of Potentially Impacted Soil Preliminary assessment of the potentially impacted soil will include confirmation that access control measures installed by the General Contractor are adequate to provide necessary protection to onsite workers and visitors. Air monitoring will be conducted by the Environmental Consultant around the perimeter of the delineated area using a PID to measure organic vapors in the breathing zone. The air monitoring results will be used to adjust the delineated area to provide necessary 3 In order of priority, the SLs are currently available DTSC-modified SLs followed by USEPA RSLs.

880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 4 RMD ENVIRONMENTAL SOLUTIONS, INC. -4
protection to onsite workers and visitors. Additional engineering controls (i.e., dust and vapor mitigation and working upwind of the area) and personal protective equipment (PPE) may be required in order to work within the delineated area.

The Environmental Consultant will conduct this preliminary assessment using PID measurements to determine if field observations suggest that the potentially impacted soil are de minimis (i.e., consistent with background levels) or may be a significant risk to human health or the environment (e.g., consistent with the BAAQMD contaminated soil definition).

If field observations (e.g., visual and odor indicators) and PID measurements are consistent with background levels, the suspect conditions will be considered de minimis and the Environmental Consultant will release the delineated area to the General Contractor. If field observations indicate additional evaluation is warranted, ground-disturbing activities will not resume in the area until the procedures discussed in the following section are implemented.

4.3.2 Evaluation of Potentially Impacted Soil
If conditions in the delineated area are not considered de minimis, the Environmental Consultant will evaluate the potentially impacted soil in accordance with the protocols below. • Soil Segregation: Soil samples will be collected using a pre-cleaned hand trowel or drive sampler, transferred into plastic Ziploc bag and observed for evidence of odors and staining and screened for volatile organics using a PID. PID measurements will be used to further segregate soil into de minimis, interim, and contaminated stockpiles. • Stockpiled Soil Samples: For the contaminated stockpile, four discrete samples will be collected and composited by the laboratory for every 250 cubic yards of material or in accordance with the requirements of the disposal/accepting facility requirements. • Sample Handling and Laboratory Analysis: Soil samples will be analyzed for VOCs by USEPA Method 8260B, and may be analyzed for TPHg, TPHd, and TPHmo by modified USEPA Method 8015, Title 22 metals by USEPA Method 6010B/7470 and other constituents as determined by the Environmental Consultant or as part of waste characterization testing for offsite disposal. If necessary, waste extraction test [WET] and/or toxicity characteristic leaching procedure [TCLP] will be conducted to determine if the soil exhibits hazardous characteristics.

Based on the evaluation, options for onsite reuse, or offsite disposal of the affected soil will be developed. After the evaluation is completed, the Environmental Consultant will provide the Revised Soil and Groundwater Management Plan
880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 4 RMD ENVIRONMENTAL SOLUTIONS, INC. -5
Property Owner, General Contractor, and DTSC with a summary of findings in the Construction Completion Report (Section 10.0).

4.4 Soil Sampling
Discrete samples will be collected using EnCore or Terra Core samplers4 for samples to be analyzed for VOCs. In addition, composite samples will be collected using a pre-cleaned hand trowel and transferred into laboratory-supplied glass containers or drive sampler equipped with stainless steel or brass liners that will be sealed with Teflon tape and capped.

Following soil sample collection, the containers will be labeled for identification and immediately placed in a chilled, thermally-insulated cooler containing bagged ice or blue ice. The cooler containing the samples will then be delivered under chain of-custody protocol to a state-certified laboratory.

4.5 Stockpile Management
Stockpile handling procedures and control measures are discussed in Section 8.1.

4.6 Dust Control Measures
As necessary, dust control measures shall be used during excavation, soil segregation, soil stockpiling, transport, and compaction activities to prevent or control surface and air movement of dust from disturbed soil surfaces. Dust control measures are discussed in Section 6.0.

4.7 Decontamination
Decontamination procedures for construction equipment and personnel shall be developed and followed to minimize residual contamination from leaving the Site during redevelopment activities.

Decontamination procedures are discussed in Section 8.4.

4.8 Soil Importation
If additional fill is imported, the following procedures will be followed for use at the Site. Unless from a documented clean source, soil samples will be collected from the import source for characterization to ensure that soil imported onto the Site is not contaminated. Import fill material will be sampled in accordance with the DTSC Information Advisory Clean Imported Fill Material, 4 U.S. Environmental Protection Agency (USEPA) Method 5035 will be used to minimize VOC loss.

Revised Soil and Groundwater Management Plan
880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 4 RMD ENVIRONMENTAL SOLUTIONS, INC. -6
dated October 2001 (Appendix E) for specific laboratory analyses based on the fill source characteristics, as follows:
• TPHg, TPHd, and TPHmo by modified USEPA Method 8015;
• VOCs by USEPA Method 8260B (with collection by USEPA Method 5035); • Semi-Volatile Organic Compounds (SVOCs) by USEPA Method 8270C; • Title 22 Metals by USEPA Method 6010B and 7471A;
• Polychlorinated Biphenyls (PCBs) by USEPA Method 8082; • Asbestos by California Air Resources Board Method 435 (CARB); and • Organochlorine Pesticides (OCPs) by USEPA Method 8081 and chlorinated herbicides by USEPA Method 8151 (for fill source areas formerly used as agricultural land); For in-place import material, the following sampling frequency is required:
• Two acres or less – a minimum of four samples.
• Two to four acres – a minimum of one sample per 1/2 acre. • Four to 10 acres - a minimum of eight samples.
• Greater than 10 acres- a minimum of eight locations with four subsamples per location.

For excavated and stockpiled import material, the following sampling frequency is required:
• Up to 1,000 cubic yards – one sample per 250 cubic yards. • 1,000 to 5,000 cubic yards – 4 samples for the first 1,000 cubic yards plus one sample per each additional 500 cubic yards.
• Greater than 5,000 cubic yards – 12 samples for the first 5,000 cubic yards plus 1 sample per each additional 1,000 cubic yards.

If the chemical properties of an import fill source are verified through documentation, sampling may not be required. Depending on the former land use of the import fill source, additional sampling and analyses than described above may be necessary to properly characterize import fill. The analytical results of the import soil samples will be compared to applicable screening criteria to evaluate whether the material is suitable for import to the Site. Applicable screening criteria will include DTSC soil SLs for direct exposure for commercial/industrial land use and acceptable background levels for metals. Import soil with visual or olfactory evidence of petroleum hydrocarbons is prohibited.

4.9 Concrete Reuse
In an effort to reduce impacts to the neighboring community and minimize carbon emissions from trucking, onsite reuse of concrete and asphalt produced during demolition of the current buildings and pavement is planned. Concrete will be crushed onsite and reused as fill material. Asphalt will be incorporated into new pavement surfaces.

4.10 Backfilling
Portions of the Site will be backfilled in accordance with the grading plan for the Site. A plastic liner will be placed to demarcate the contact between fill material and native soil.

5.0 CONTINGENCY MEASURES FOR DISCOVERY OF

UNEXPECTED UNDERGROUND STRUCTURES
In the event USTs or other buried structures are unexpectedly encountered during redevelopment activities, the following procedures will be followed. USTs may be identified during redevelopment activities by the presence of vent pipes that extend above the ground surface, product distribution piping that leads to the UST, fill pipes, backfill materials, or the underground structure itself. Other buried structures may not have features that extend above ground surface and could be discovered only after exposed by construction equipment. Discovered structures will be assessed as follows:

5.1 Initial Response
If unexpected underground structures, including tanks, vaults, sumps, containment structures, separators, or piping, that has previously contained or has the potential to contain hazardous materials are encountered during redevelopment activities, the General Contractor will notify the Property Owner and the Environmental Consultant within 24 hours of initial discovery. Upon notification, the Environmental Consultant will notify the DTSC and the SLESS, which is designated as the Certified Unified Program Agency (CUPA). The CUPA consolidates, coordinates, and makes consistent the administrative requirements, permits, inspections, and enforcement activities associated with the regulation of hazardous materials and hazardous wastes in the City of San Leandro through various programs. The DTSC and the SLESS will be consulted regarding appropriate next steps.

In accordance with the Site HASP, appropriate measures will be implemented to ensure worker safety in areas where unexpected conditions are encountered. The General Contractor or designated Health and Safety Officer will be responsible for evaluating any change in Site conditions and may stop work to determine if the level of Site security and PPE is adequate. If warranted, the area where the unexpected condition is encountered will be secured with barricades or fencing, and plastic sheeting as appropriate, and signage will be installed to prevent unauthorized access to the area.

5.2 Assessment of Discovered Underground Structures
Discovered underground structures will be assessed as follows:
• The structure will be inspected to assess whether it contains any indication of chemical residuals or free-phase liquids other than water. This assessment will be conducted by the Environmental Consultant and will be based on visual evidence and the results of vapor Revised Soil and Groundwater Management Plan
880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 5 RMD ENVIRONMENTAL SOLUTIONS, INC. -2
monitoring using a PID. Under no circumstances will any personnel enter an unknown subsurface structure at any time;
• If chemicals are not indicated within the structure by the above-referenced means, and with DTSC and SLESS approval, the structure may be removed or abandoned in place in a safe manner by an experienced and licensed contractor. If warranted, permits will be obtained from the SLESS prior to removing the underground structure; • If liquids or solids are present within the structure, measures will be taken to contain the liquids to avoid spills to the subsurface. Liquids will be contained either in the structure or, if leaking, via spill control methods such as absorbent material and pumping to a storage tank. Samples of the liquid will be collected and submitted to a state-certified laboratory for analysis as determined by the Environmental Consultant or as part of waste characterization testing for offsite disposal. Based on analytical results, the liquids or solids will be disposed of in accordance with applicable environmental laws and disposal requirements;
• If contaminated liquid or solids are present in the structure, the structure will be inspected for physical integrity following removal of the contaminated media. The Environmental Consultant will document the results of this inspection, including an estimation of the volume and former use of the structure;
• If the physical inspection of the structure suggests that chemicals may have been released to the underlying soil, additional environmental sampling will be conducted to assess whether over-excavation is warranted;
o If, based on the opinion of the Environmental Consultant, DTSC, and SLESS, it is assessed that the structure is intact, that subsurface releases of the chemicals to the underlying soils likely did not occur, and no free-phase liquids or chemical residues remain inside, removal of the structure may not be required for environmental reasons.
o Otherwise, with DTSC and SLESS approval, the structure will be removed and disposed of in accordance with applicable environmental laws and disposal requirements. Once the structure is removed, soil adjacent to and beneath the structure will be assessed for contamination through visual observation and PID response and the results documented. If soil is considered “contaminated soil” as defined by the BAAQMD, the appropriate response will be determined in consultation with the DTSC and SLESS.

6.0 EROSION, DUST, AND ODOR MANAGEMENT
Once the pre-construction ground surface is stripped from the Site, the exposed soil will become susceptible to erosion by wind and water. Depending on soil and weather conditions, airborne dust and fugitive emissions may be produced. Therefore, erosion control measures and dust control measures will be established before construction begins. Emission (dust) control measures will, at a minimum, comply with those established by OSHA and the BAAQMD for construction-related activities. Dust control measures will be based on "Best Management Practices" (BMPs) and will be used throughout the phases of redevelopment. Standard dust and fugitive emissions control measures will be followed during the redevelopment activities to accomplish the following goals:
• Reduce the potential for health impacts to onsite workers and visitors; • Reduce the potential for health impacts to offsite receptors; • Prevent violations of ambient air quality standards;
• Minimize nuisance dust complaints from offsite receptors; and • Minimize the migration of contaminants adhered to fugitive dust particles outside the Site.

6.1 Construction Mitigation Measures
The following basic construction mitigation measures will be implemented in accordance with recommendations in the BAAQMD California Environmental Quality Act Air Quality Guidelines (BAAQMD, 2017):
• Exposed surfaces (e.g., parking areas, staging areas, graded areas, and unpaved access roads) will be watered two times per day, weather dependent. Alternately, soil binders can be applied in areas that will remain unused;
• Haul trucks transporting soil or other loose material offsite will be covered; • Prior to entering public roads, visible loose soil will be removed from the vehicle exterior using dry methods (e.g., shovels and stiff-bristled brooms or brushes). If visible mud or dirt is tracked-out onto adjacent public roads, a wet power vacuum street sweeper will be used.

The use of dry power sweeping is prohibited;
• Vehicle speeds on unpaved roads will be limited to 15 miles per hour (mph); • Roadways, driveways, and sidewalks to be paved will be completed as soon as possible.

Building pads will be laid as soon as possible after grading unless seeding or soil binders are used;
Revised Soil and Groundwater Management Plan
880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 6 RMD ENVIRONMENTAL SOLUTIONS, INC. -2
• Idling times will be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne toxics control measure 13 CCR 2485). Clear signage will be provided for construction workers at all access points;
• Construction equipment will be maintained and properly tuned in accordance with manufacturer‘s specifications. Equipment will be checked by a certified mechanic and determined to be running in proper condition prior to operation; and • A publicly visible sign that includes the General Contractors name and telephone number to contact regarding dust complaints will be posted. When contacted, the General Contractor will respond and take corrective action within 48 hours. The BAAQMD’s phone number will also be visible to ensure compliance with applicable regulations.

6.2 Dust Suppression Measures
If dust is excessive, one or more of the following mitigation measures may be implemented:
• Apply water or (non-toxic) soil stabilizers to unpaved access roads, parking areas, and staging areas;
• Sweep (with wet power sweepers) paved access roads, parking areas, and staging areas; • Cover or otherwise stabilize exposed soil stockpiles; and • Suspend redevelopment activities that cause visible dust plumes and odors to extend beyond the limits of the Site.

6.3 Contingency Measures for Odor and Vapor Suppression By controlling the dust as described above, the emission of odor and vapors will be reduced to levels that likely will not pose a risk to the health of the onsite workers and visitors. The water spray used to control dust will also significantly reduce the emissions of any potential volatiles that may be present in the soil. The selective loading and transportation of impacted soils could minimize the use of soil stockpiling, further reducing potential emissions of volatiles. Any active stockpile of contaminated soil will be properly covered with plastic so emissions of volatiles will be minimized.

If odor is excessive and vapor emissions are detected, one or more of the following contingency measures may be implemented:
• Apply water or water containing a non-toxic biodegradable deodorizer, odor suppressing foam, or other odor mitigation agents to exposed soil using various applications such as spray or mist;
Revised Soil and Groundwater Management Plan
880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 6 RMD ENVIRONMENTAL SOLUTIONS, INC. -3
• Alternative work sequencing, such that excavation of soil with potential odor during mid-day or afternoon (during hot weather) is avoided;
• Any highly odorous soil could be segregated and placed inside a roll-off bin equipped with a lid. This will minimize the amount of highly odorous soil handling; and • Balancing the excavation with transportation so that the need for large stockpiles is reduced.

The equipment proposed for the Site redevelopment will be maintained properly so that exhaust emissions will be within acceptable standards. The General Contractor will notify the Property Owner of complaints, if any, and record any corrective actions implemented to control odors or vapors in a daily field log.

7.0 GROUNDWATER MANAGEMENT
The depth to groundwater at the Site is typically encountered at depths of approximately 5 to 7 feet bgs. In general, construction worker receptors will be performing activities consistent with this SGMP and a Site HASP. The HASP will require the use of proper PPE and the BMPs will require dewatering to preclude any direct contact with groundwater for workers at the Site.

Construction dewatering effluent, if produced, shall be pumped into holding tanks or United Nations (UN)-rated 55-gallon drums with appropriate labeling and secondary containment. If dewatering effluent is to be discharged to the storm drain, a National Pollutant Discharge Elimination System (NPDES) permit will be obtained from the Regional Water Quality Control Board.

If dewatering effluent is to be discharged to the San Leandro Water Pollution Control Plant, an industrial pre-treatment permit will be obtained from the SLESS.

Chemical analysis will be performed in accordance with the receiving facility’s requirements prior to discharge. If concentrations exceed the limits established for the discharge point, the dewatering effluent will either be (1) transferred into a vacuum truck or properly labeled UN-rated 55-gallon drums and transported offsite for disposal at an appropriately-licensed disposal facility or (2) treated and discharged following sampling and analysis to confirm compliance with permit requirements.

The treatment system of the dewatering effluent would include a holding tank, sediment filters, and two carbon vessels to treat the effluent prior to storm drain or sanitary sewer discharge. The sizing of components will depend on the water volumes produced and Site logistics. A typical treatment system schematic is shown in Figure 6.

8.0 WASTE MANAGEMENT

8.1 Soil Stockpile Management
Soil that is placed in temporary stockpiles will be maintained to prevent runon/runoff and fugitive dust emissions. The soil stockpile will be covered with plastic sheeting and bermed to prevent (1) erosion or leaching of contaminants to underlying soil, (2) exposure to precipitation and wind, and (3) the runoff of potential contaminants to surrounding areas. Plastic sheeting that covers the soil stockpile will be secured using sand bags or equivalent. The perimeter berm will be constructed with hay bales, dimensional lumber, or other equivalent methods. Following removal, the soil stockpile area will be restored to a pre-stockpile condition. Residual plastic or debris will also be disposed of following stockpile removal.

If soil stockpiling of potentially impacted soil is to be performed, an appropriate stockpile location will be established and stockpiled soil will be placed on plastic sheeting. Stockpiled soil will be secured with a berm (bottom plastic sheeting will be lapped over the berm materials), covered to control dust, profiled, and appropriately managed as described in the following sections.

8.2 Offsite Disposal
Soil that is not suitable for reuse will be transported offsite for disposal at a facility that possesses a current permit to accept the produced soil. The following website can be consulted to determine permitted facilities:
• https://www2.calrecycle.ca.gov/SolidWaste/Site/Search Prior to disposing soil at an appropriately-licensed disposal facility, soil samples will be collected from the potential excavation area or stockpiled for characterization based on the source characteristics and disposal facility requirements. These requirements will be confirmed by the General Contractor and coordinated with the proposed receiving facilities prior to initiating soil sampling.

8.3 Soil Handling, Loading, and Transporting Procedures Following acceptance of the soil by an appropriately-licensed disposal facility, the soil will be loaded in licensed haul trucks (end-dumps or transfers) and transported offsite following appropriate California and Federal waste manifesting procedures. The General Contractor, on behalf of the Property Owner, will be responsible for tracking final soil dispositions. Shipments of waste will be Revised Soil and Groundwater Management Plan
880 Doolittle Drive and 498 Hester Street, San Leandro, California June 11, 2021 8 RMD ENVIRONMENTAL SOLUTIONS, INC. -2
tracked with the appropriate bill of lading or waste manifests, which will be provided to the Property Owner following completion of the redevelopment activities.

Transportation equipment will be chosen to safely transport the expected volumes of soil, taking into consideration the types of roads to be traveled and their loading capacity. The appropriate bill of lading or waste manifest documentation will be provided by the General Contractor to truck drivers hauling the soil offsite. As each truck is filled, an inspection will be made to verify that the load is securely covered, to the extent practicable, and that the tires of the haul trucks are reasonably free of accumulated soil prior to leaving the Site. During loading, dust and odor emissions will be monitored and mitigated as necessary. During transportation, the hauling trucks will be equipped to fully cover soil and debris, such as with a heavy tarpaulin. A street sweeper will be made available, as needed, to keep the loading area clean. The soil will be wetted, as necessary, to reduce the potential for dust generation during loading and transportation activities.

Transportation activities will be performed in strict compliance with Federal, State, and County regulations and ordinances. Hauling contractor(s) used to transport soil will be fully licensed and permitted by the State of California. For hazardous waste haulers, the selected transportation company will be certified by the State of California as a hazardous waste hauler, and appropriately permitted to haul contaminated waste material. Department of Transportation (DOT) and California Highway Patrol (CHP) safety regulations will be strictly followed by both hazardous and nonhazardous waste haulers.

Transportation routes will be developed to minimize transporting the affected soil through residential areas. The affected soil will be transported via surface streets to the closest suitable freeway, which is Interstate 880. The proposed routes for transportation to Interstate 880 are as follows:
• To Interstate 880 North and South: Leaving the Site along Doolittle Drive, travel southeast approximately 0.25-miles to Davis Street. At Davis Street, make a left-hand turn. Travel east along Davis Street approximately 0.6 miles to the I-880 north and south ramps. Use the appropriate ramp to enter I-880.

The remainder of the freeway route(s) will be established upon selection of the appropriate offsite destination.

8.4 Decontamination Procedures
In order to prevent residual contamination from leaving the Site by construction equipment and personnel during redevelopment activities, the following decontamination procedures will be followed:
• Trucks used to transport soil will be loaded in a manner to minimize soil spillage and fugitive dust.
• To minimize the spread of contaminated soil, equipment will be cleaned prior to movement out of active work zones in impacted areas. The equipment wheels/tires will be cleaned by means of shovels and stiff-bristled brooms or brushes until they are fully cleaned. Upon completion of cleaning, any debris will be placed in the appropriate transportation vessel and the plastic sheeting will be disposed. Equipment exiting the Site will be inspected and logged for compliance with the Site decontamination requirements. • Disposable PPE will be removed and properly discarded. The Site HASP will address decontamination of reusable PPE.

8.5 Wastewater and Groundwater Management
Wastewater produced during redevelopment activities, such as decontamination liquids, will be temporarily stored onsite. Decontamination water will be profiled and transported to an appropriate disposal or recycling facility.

If a saturated zone that produces accumulated water is encountered during redevelopment activities, groundwater management protocols as discussed in Section 7.0 will be followed.

8.6 Spill Response Plan
In the event of a spill, the General Contractor will be responsible and prepared to respond in a safe and efficient manner, specific to the particular spill situation. Consistent procedures will be used for handling of spills, whether they are onsite spills or spills occurring during transportation. Haulers will have an Emergency Spill Contingency Plan (ESCP) to ensure that drivers and dispatchers know their responsibilities in the unlikely event that an accidental spill occurs while transporting contaminated material offsite. The drivers and dispatchers will be required to know the procedures for emergency spill response. The ESCP will meet or exceed Federal, State, and County regulations currently in effect. The provisions of the ESCP will be strictly adhered to, in order to ensure continued protection of the public safety and the environment. The HASP will address the handling of onsite spills.

9.0 STORMWATER MANAGEMENT
Stormwater pollution controls shall be implemented by the General Contractor to minimize sediment runoff in stormwater. BMPs including grading the Site and installing stormwater control devices such as temporary earth berms or erecting silt fences around the perimeter of exposed soil at the Site, shall be implemented to prevent erosion and sediment runoff from the Site. Straw bale barriers or sediment traps are required to protect any existing catch basins or drainage channels. A separate stormwater pollution prevention plan (SWPPP) shall be provided by a Qualified SWPPP Developer (QSD) prior to beginning redevelopment activities.

10.0 WRITTEN RECORDS AND REPORTING
During redevelopment activities, soil and/or groundwater sampling, removal and management of discovered underground structures, chemical analysis and proper disposal of contaminated materials, and soil import activities will be documented in a daily field log by the General Contractor and/or Environmental Consultant. At the completion of the redevelopment activities, a Construction Completion Report will be prepared by the Environmental Consultant for submittal to DTSC that summarizes the soil and groundwater handling activities. The report will include at a minimum the following, as applicable:
• Impacted Soil – origin, volume, characterization, and destination (disposed of offsite); • Discovered Underground Structures – type, contents, characterization, and destination (abandoned in place or disposed of offsite);
• Dust Complaint Logs – time, name and contact information, complaint description, and measures taken to mitigate dust;
• Groundwater – volume of groundwater that is removed, characterization, treatment, and destination (used as dust suppression or disposed of offsite); • Offsite Disposal Records – date, time, vehicles used for the trip, volume/weight, copies of bills-of-lading, and waste manifests;
• Imported Soil – origin, volume, and characterization; and • Analytical Reports – copies of laboratory analytical results.

COVENANT TO RESTRICT USE OF PROPERTY

ENVIRONMENTAL RESTRICTION
County of Alameda APNs 77A-741-4-2 and 77A-741-5, Former Kaiser Aerotech Site, DTSC site code number 200559
This Covenant and Agreement ("Covenant") is made by and between Redemco, L.L.C, (the "Covenantor"), the current owner of property situated in San Leandro, County of Alameda, State of California, described in Exhibit "A" and depicted in Exhibit “B,” attached, (the "Property"), and the Department of Toxic Substances Control (the "Department"). Pursuant to Civil Code section 1471, the Department has determined that this Covenant is reasonably necessary to protect present or future human health or safety or the environment as a result of the presence on the land of hazardous materials as defined in Health and Safety Code section 25260. The Covenantor and Department, collectively referred to as the "Parties," hereby agree, pursuant to Civil Code section 1471, and Health and Safety Code section 25355.5 that the use of the Property be restricted as set forth in this Covenant; and the Parties further agree that the Covenant shall conform with the requirements of California Code of Regulations, title 22, section 67391.1.

ARTICLE I

STATEMENT OF FACTS

1.01. The Property, totaling approximately 14 acres, is more particularly described as 880 Doolittle Drive and 498 Hester Street in the City of San Leandro, County of Alameda, California, and is depicted in the attached Exhibits "A" and “B”. The Property is located in the area now generally bounded by Doolittle Drive on the west, Hester Street on the north and Davis Street on the south. The Property is also described as Alameda County Assessor's Parcel Numbers 77A-741-4-2 and 77A-741-5.

1.02. A limited portion of the Property is more particularly described in Exhibit "C," and referred to as the Ground Water Monitoring System. The Ground Water Monitoring System consists of groundwater monitoring wells located throughout the entire Property.

1.03. Covenantor is remediating the Property under the supervision and authority of the Department. The Property is being remediated pursuant to a Remedial Action Plan developed in accordance with Health and Safety Code, division 20, chapter

6.8 under the oversight of the Department. The Remedial Action Plan (RAP) and notice of exemption, pursuant to the California Environmental Quality Act, Public Resources Code section 21000 et seq. were released for public review and comment and subsequently approved by the Department on February 26, 2008. A Covenant is required as part of the site remediation, because volatile organic compounds (VOCs), which are hazardous substances, as defined in Health and Safety Code section 25316, and hazardous materials as defined in Health and Safety Code section 25260, remain above unrestricted cleanup goals in groundwater and shallow soil below the surface of the property.

Remediation includes maintaining groundwater monitoring wells ("Monitoring Wells").

Page 2 ends

The locations of the Monitoring Wells are shown on Exhibit C. The operation and maintenance of the Monitoring Wells is being conducted pursuant to an Operation and Maintenance Plan approved by the Department on June 27, 2012.

1.04. Soil investigations identified contaminants at concentrations exceeding residential screening levels in limited areas of the Property. As detailed in the RAP, a limited portion of the subsurface soils within six feet of the surface of the Property, as more particularly described in Exhibit D, contain a hazardous substance (trichloroethene; TCE), as defined in Health and Safety Code section 25316. The maximum TCE concentration detected in soil within six feet of the surface was 1,100 pg/kg. This exceeds the Environmental Protection Agency Regional Screening Level for TCE in soil for residential use (910 pg/kg ).

As detailed in the RAP, groundwater at the Property is found 5 to 7 feet below ground surface (bgs) and extends beyond 40 feet bgs. As of June, 2012, contaminants in the groundwater above their associated California Maximum Contaminant Levels (drinking water standards) are: TCE; cis-1,2-DCE; trans 1,2-DCE; 1,1-DCE; 1,1-DCA; 1,2-DCA; and vinyl chloride (VC).

The Department concluded that use of the Property as a residence, hospital, school for persons under the age of 21 or day care center would entail an unacceptable human health risk and exposure to and use of the groundwater presents an unacceptable threat to human health and safety. The Department further concluded that the Property, as remediated, and subject to the restrictions of this Covenant, does not present an unacceptable threat to human health or safety or the environment, if limited to commercial and industrial use and limited by the other Environmental Restrictions herein.

Samples will be collected at these Degreasing Tank no. 1 wells based on semi-annual (third quarter) field parameter readings.

If ORP is above 0 mV, pH is below 5.0/above 9.0, and/or specific conductance is below 1,200 µS/cm, a sample will be collected for HVOC analysis.

Samples will be collected at wells RW-5 and RW-8 based on annual field parameter readings. If ORP is above 0 mV, pH is below 5.0/above 9.0, and/or specific conductance is below 1,200 µS/cm, a sample will be collected for HVOC analysis.

Samples will be collected and field parameters will be measured at the C-zone wells if water levels indicate a downward hydraulic gradient between the B-zone and C-zone. Samples will be analyzed for HVOCs.

Discretionary samples from treatment areas may also be analyzed for ethene, ethane and methane using Method RSK 175M and/or total organic carbon using Standard Method 5310D. These supplemental analyses will be evaluated based on field parameters, and findings for nearby monitoring wells.
