RE: Pre-Renovation Hazardous Materials Survey Union Sanitary District – Covered Storage Structure

5072 Benson Rd, Union City, CA 94587

Dear Trapa Barua:

Executive Summary

At your request, Vista Environmental Consulting (Vista) performed a pre-renoavtion hazardous material survey of the Covered Storage Structure, located at the Union Sanitary District, 5072 Benson Rd, Union

City, CA 94587 (Project Site). The survey was performed to identify and sample accessible suspect asbestos-containing materials (ACM), to identify representative building components for the presence of lead-containing surface coatings/lead-based paints (LCSC/LBP), and to visually identify universal waste

(UW) materials, polychlorinated biphenyls (PCBs) containing devices, devices which contain ozone depleting chemicals, and other hazardous materials. The hazardous materials survey was performed on

September 5, 2024 by Vista employee Christopher Burns and Javier Rocha.

Asbestos

The results of the bulk samples collected for asbestos analysis indicate that detectable concentrations of asbestos are present in the following materials:

No asbestos was detected in the 10 samples collected and analyzed

Lead

Methodology

Vista performed the hazardous materials survey on September 5, 2024. The hazardous materials survey was conducted by Christopher Burns, a State of California Division of Occupational Safety and Health

(Cal/OSHA) Certified Asbestos Consultant (CAC) #92-0224, and a State of California Department of

Public Health (CDPH) Lead Related Construction Inspector Assessor (LRCIA) LRC-6938. Assisting on the survey was Javier Rocha, a Cal/OSHA Certified Site Surveillance Technician (CSST) #02-3244 and a

CDPH Lead-Related Construction Certified Sampling Technician (LRCST) LRC-00000629.

The pre-renovation asbestos survey was performed generally in accordance with the AHERA protocol (40

CFR Part 763, Subpart E). Visual identification was conducted by assessing visible and accessible structural, architectural, and mechanical components in the path of construction for the presence of suspect asbestos-containing material (ACM) at the Project Site. Each identified suspect ACM was sampled in accordance with procedures established by the United States Environmental Protection

Agency (USEPA).

Suspect ACM samples were delivered under chain-of-custody protocol to SGS Forensic Laboratories

(Forensic) in Hayward, California. Forensic is accredited under the National Voluntary Laboratory

Accreditation Program (NVLAP) and the California Environmental Laboratory Accreditation Program

(Cal-ELAP). The samples were submitted for analysis by Polarized Light Microscopy (PLM) utilizing dispersion staining techniques in accordance with the EPA’s “Method for the Determination of Asbestos in Bulk Building Materials” U.S. EPA/600/R-93/116, Visual Area Estimate, dated July 1993 and adopted by the NVLAP as Test Method Code 18/A01.

The lead bulk samples were collected following United States Department of Housing and Urban

Development (HUD) Appendix 13.2: Paint Chip sampling from the Guidelines for the Evaluation and

Control of Lead-Based Paint Hazards in Housing, June 1995 and was delivered, under proper chain-of-custody protocol, to Forensic. Forensic is accredited under American Industrial Hygiene Association

(AIHA), the Environmental Lead Laboratory Accreditation Program (ELLAP), and the California

Buil de r's Exc ha

Department of Public Health (CDPH) for multiple metals analysis. The samples were prepared and analyzed by method EPA 3050B/7420, Flame Atomic Absorption.

Devices with Potential Hazardous Materials

Devices with potential hazardous materials were visually identified during the survey walk through and their quantities were estimated and recorded. No attempt was made to disassemble devices or sample suspect materials within the devices. For example, fluorescent light fixtures must be presumed to contain

Universal Waste lamps and ballasts which contain PCB oil or are electronic waste, pending removal and disassembly of each unit to determine explicit product specific information that proves otherwise.

Results

The results of the bulk samples collected for asbestos, and analyzed by PLM, or assumed, indicate that detectable concentrations of asbestos are present in the following materials:

No asbestos was detected in the 10 samples collected and analyzed.

The results of the bulk samples collected for asbestos, and analyzed by PLM, indicate that detectable concentrations of asbestos are not present in the following materials:

For purposes of this survey, and in accordance with Title 8 CCR, Section 1532.1 (8 CCR 1532.1) and

Title 17 of the California Code of Regulations, Section 35001 et. seq. the bulk paint chip sample or XRF direct read instrument results were interpreted as follows:

1. Lead-based paints (LBP) and lead-based materials (LBM) are present when bulk paint chip samples reveal a lead concentration of ≥5,000 milligrams per kilogram (mg/kg) or parts per million (ppm), 0.5% by weight (wt%) or ≥1.0 milligrams per centimeter squared (mg/cm²) via XRF direct read instrument sampling.

2. Lead-containing paints (LCP) and lead-containing materials (LCM) are present when bulk paint chip samples reveal a lead concentration of <5,000 mg/kg or 0.5 wt% down to the analytical detection limit of the analysis, or <1.0 milligrams per centimeter squared (mg/cm²) via XRF direct read instrument sampling down to the detection limit of the device.

3. “No lead detected” was determined when bulk paint chip samples did not reveal a lead concentration above the analytical detection limit of the laboratory or direct read instrument sampling device.

The bulk paint chip results results for this survey indicated that the following building components and respective surface coatings have lead concentrations defining them as LBP, in accordance with Title 17 of the California Code of Regulations, Section 35001 et. seq.:

None

The bulk paint chip sample results results for this survey indicate that the following building components and respective surface coatings have lead concentrations, in excess of the level for compliance with trigger activities, as defined in 8 CCR 1532.1:

Conclusions/Recommendations

The results of the survey indicate that asbestos-containing materials are not present at the Project Site.

The results of the lead sampling indicate that lead-containing paint is present at the Project Site.

At present there is no state or federal regulation requiring mandatory lead removal or abatement prior to disturbance of building materials with identified lead paint or coatings. However, there are applicable

Cal/OSHA worker protection and training requirements, Cal/EPA waste disposal requirements, CDPH requirements for public and residential buildings, and SB 460 lead hazard regulations that apply to lead-related construction activities, abatement activities and their associated wastes.

The following is a brief discussion and summary of applicable regulatory requirements:

♦ Cal/OSHA: Title 8, California Code of Regulation (CCR), Section 1532.1 (8 CCR 1532.1) governs occupational exposure to lead. This regulation requires that prior to initiation of certain activities, referred to as “trigger tasks”, workers must be trained, medically evaluated, and properly fitted with respiratory protection, and protective clothing until statistically reliable personal eight-hour time weighted average

(TWA) results indicate lead exposure levels below the Personal Exposure Limit (PEL) for each unique task which disturbs lead-based and lead-containing coatings. This process is known as a Negative

Exposure Assessment or NEA.

If the result of the exposure assessment is above the Action Level (AL) additional monitoring is required and if the result is above the PEL additional exposure monitoring, worker protection (including respirator protection and PPE), training and medical requirements apply. However even where the NEA criteria is met, certain hazard communication training and work practice controls still apply where lead is disturbed.

“Trigger tasks” are tasks that are assumed to exceed the PEL pending an exposure assessment and they encompass the majority of construction activities that disturb surface coatings. Examples of “trigger” tasks range from manual paint scraping as a lower expected exposure up to hot work and abrasive blasting as the highest expected exposures, and include any non-listed task that the employer determines may potentially expose employees to lead levels above the AL.

“OSHA does not consider any method that relies solely on the analysis of bulk materials or surface content of lead (or other toxic material) to be acceptable for safely predicting employee exposure to airborne contaminates. Without air monitoring results or without the benefit of historical or objective data (including air sampling which clearly demonstrates that the employee can not be exposed above the action level during any process, operation, or activity) the analysis of bulk or surface samples can not be used to determine employee exposure.”- OSHA Standard Interpretation May 8, 2000.

Buil de r's Exc ha

OSHA states that these rules apply to “any detectable concentration of lead” without a specified detection level. Due to the Consumer Product Safety Commission currently allowing paint to contain up to 90 parts per million (ppm) or 0.009 wt% of lead, the variation of lead content due to aging and weathering, and the variation of detection limits associated with analysis of bulk materials, such as paint chips and surface content analysis via XRF, it is recommended that all painted or coated surfaces be treated as potentially containing lead. Positive analytical results by either method can be used to indicate that detectable lead is present but negative results cannot be interpreted as conclusively demonstrating the absence of lead.

Analytical data from analysis of bulk materials or surface content of lead can be helpful in evaluation of lead-related environmental risks in general but cannot be used to calculate worker exposures and are not a substitute for employee exposure monitoring. As a result of the above, any employee that works around potential lead-based or lead-containing coatings must have HAZCOM training and personal exposure air monitoring is additionally required for employees that disturb such coatings. Significant additional certification, notification, and work practices are required for materials found to be lead-based.

Any welding, cutting or heating of metal surfaces containing surface coatings should be conducted in accordance with 29 CFR 1926.354 and 8 CCR 1537. These regulations require surfaces covered with toxic preservatives, and in enclosed areas, be stripped of all toxic coatings for a distance of at least 4 inches, in all directions, from the area of heat application prior to the initiation of such heat application.

Vista recommends that the paint is stripped 12 inches, in all directions, from the area of heat application prior to the initiation of such heat application.

♦ Cal/EPA through the Division of Toxic Substance Control (DTSC) regulates disposal of lead hazardous waste (22 CCR Division 4.5, Minimum Standards for Management of Hazardous and Extremely

Hazardous Wastes). DTSC has issued guidance indicating that architectural debris with intact lead paint is normally expected to be handled as general construction waste. However, waste stream segregation and analysis is still required for all lead painted or coated debris regardless of if the paint or coating is intact on a building component or not. The resulting wastes may be hazardous under California and federal

RCRA standards for lead and therefore require proper handling, packaging, labeling, and transportation under a proper manifest to a permitted hazardous waste storage, treatment and disposal facility.

♦ CDPH: The Department of Public Health (CDPH) has specific requirements (Title 17 Sections 35001 thru 36100 et. al.) for hazard assessment and work in public or residential structures in regards to lead-based paint. These regulations require special certifications, work practices, and notification for such activities.

♦ Senate Bill 460 (SB 460): An act to amend Section 1941.1 of the Civil Code, and to amend Sections

17961, 17980, and 124130 of, and to add Sections 17920.10, 105251, 105252, 105253, 105254, 105255, 105256, and 105257 to, the Health and Safety Code, relating to lead abatement. This bill allows for fines and criminal penalties to be levied on any person who is found to have performed lead abatement without

Buil de r's Exc ha containment or created a measurable “lead hazard” based upon current CDPH standards. A “lead hazard” means deteriorated lead-based paint, lead contaminated dust, lead contaminated soil, disturbing lead-based paint or presumed lead-based paint without containment, or any other nuisance which may result in persistent and quantifiable lead exposure.

Vista recommends that all parties that come into contact with paint that has detectable lead content follow all applicable federal, state and local regulations relating to employee health and safety and proper disposal of generated wastes.

Devices with Potential Hazardous Materials

Other hazardous materials are present at the Project Site.

All potential and identified Universal Waste materials (UW) impacted by the work should be removed and recycled or disposed of in accordance with the UW guidelines established by the DTSC, as stated in

22 CCR Sections 66261.9 and 66273.1 thru 66273.90. UW materials include, but are not limited to, non-incandescent lamps and electronic waste.

Vista’s limited visual survey indicated that light fixtures with ballasts that may contain PCB oil are present. However, due to the limited nature of the random spot checks, Vista recommends that all ballasts be visually inspected, prior to disposal, to determine if they contain PCB’s. Those ballasts marked No

PCB’s or PCB Free can be considered as such as should be treated as UW - electronic waste. All PCB-containing devices, including, but not limited to ballasts and transformers, should be removed or have the oils removed and properly handled, collected, stored, transported and recycled or disposed of by an approved recycling or disposal facility in accordance with the requirements of Title 22 CCR 67426.1.

Limitations and Exclusions

The sampling performed was limited to accessible materials and the testing of representative areas.

Destructive testing, demolition, or subsurface investigations were not included as part of this investigation.

PROCEDURES

1. Treatment Plant or Pump Station Lockout/Tagout

1.1 Planning the Work

Step 1: Prior to any work being commenced, the District and Contractor shall meet and review the District’s LOTO SOP which shall be the minimum standard operating procedure for all of Contractor’s and its subcontractors’ LOTO procedures while working in the District’s Plant or Pump Station. If an equipment specific LOTO SOP does not exist for the piece of equipment to be worked on an SOP must be developed prior to commencing the shutdown and LOTO. The Non-Routine LOTO SOP Checklist at the end of this SOP should be used by a qualified operator/pump station mechanic to develop the LOTO SOP for the subject work.

Step 2: Outside employer/contractor shall inform their subcontractors of both the District’s and their own LOTO procedures

Step 3: Contractor shall inform the District in writing who will be the Authorized Employee(s) or Primary Authorized Employee for each LOTO.

1.2 Prior to Starting Work

Each Authorized Employee or the Primary Authorized Employee shall:

Step 1: Before a machine or piece of equipment is turned off, review and follow at a minimum the individual equipment LOTO SOP (if applicable).

This equipment LOTO SOP is information for the contractor only.

Step 2: Make sure that the Authorized and Affected Employees know all of the following:

Type and magnitude of the energy

Hazards of the energy to be controlled

Method or means to control the energy

Point of attachment for the lockout device

Who the Affected Employees are

Step 3: Establish two-way communication by making a positive contact with a Plant Operator or Pump Station Mechanic prior to the initial start of a job in the Treatment Plant or Pump Station

Step 4: Notify Affected Employees that a lockout or tagout system is going to be utilized and specify the equipment and the reason for the lockout

Step 5: Survey the area to locate and identify all isolating devices to be certain which switch(es), valve(s), or other energy-isolating devices apply to the equipment to be locked or tagged out.

More than one energy source may be involved (electrical, mechanical, stored energy, or others).

TREATMENT PLANT & PUMP STATION

1.3 Shutting Down the Equipment

Step 1: When requested in advance, in writing (following the system outage request procedures as outlined in Section 01010 of the contract specifications), a Plant Operator or Pump Station Mechanic will remove equipment from service for maintenance work.

Step 2: The Plant Operator or Pump Station Mechanic will turn off or shut down the machine or equipment using established procedures as detailed in the equipment-specific LOTO SOP (e.g. depress stop button, open toggle switch, etc.)

1.4 Isolating the Energy Source

Each Authorized Employee or the Primary Authorized Employee shall:

Step 1: After the machine or equipment has been turned off, completely isolate the machine or equipment from its energy sources

Use the appropriate energy-isolating devices (i.e. breakers, valves, disconnects)

CAUTION

Only District Personnel shall shut down or turn on District equipment.

CAUTION

In addition to operating the switch, valve, or other energy-isolating device(s) so that the equipment is isolated from its energy source(s), stored energy (such as that in springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) must be released or restrained by methods such as repositioning, blocking, bleeding down, etc..

Buil de r's Exc ha

TREATMENT PLANT & PUMP STATION

Step 2: When necessary a District Mechanic or Electrician will perform the following:

Open the appropriate circuit breaker or mechanical system

Disconnect the wires from the power source and or control panels and at the local panel adjacent to the equipment and/or blank

Disconnect any identified or associated mechanical systems or piping

Step 3: Lockout / Tagout the energy-isolating devices with proper lock(s) and tag(s)

Step 4: Make sure a lockout tag is applied for each energy-isolating device

Step 5: Make sure lockout devices hold the energy-isolating device in a “safe” or “off” position

Step 6: Make sure a tag is put on an energy-isolating device so it clearly shows that moving the energy-isolating device from the “safe” or “off” position is prohibited

Step 7: If the Plant Operator or Pump Station Mechanic himself/herself would be exposed to hazardous energy by the work, he/she will place and control lock(s) and tag(s) in addition to the lock(s) and tag(s) used by the contractor.

If the Plant Operator or Pump Station Mechanic is not exposed by the work he/she will place locks and tags when requested but his/her name will not be included on any of the lockout tags.

Only the name of the Primary Authorized Employee or Authorized Employee(s) will be written on the lockout tags

Step 8: If the Plant Operator or Pump Station Mechanic will not be exposed by the work but wants to ensure Operations or Fabrication, Maintenance and Construction (FMC) control of the equipment for process reasons he/she may add a process notice tag or FMC Notice tag to the individual equipment or group lockout box.

NOTE

The Plant Operator or Pump Station Mechanic will make entries into a daily log at field locations for notification of District employees on subsequent shifts, noting the: date, time, specific name of the equipment being locked or tagged out of service, and the time and date that it is expected to return to service.

NOTE

When using a group lockout box to lockout multiple equipment the individual tags on each piece of equipment will not have a name on it. The tag will contain a date, description, and the ID of the lockout box being used. The locks and tags placed on the lockout box itself will have the name of the Authorized Employee(s) or the Primary Authorized Employee on the tag along with the date and description.

This process notice tag or FMC Notice tag will NOT be a substitute for the locks and tags of each or any exposed personnel.

Any District Operator is authorized to remove a blue District process notice tag

Any FMC Personnel is authorized to remove a yellow District FMC Notice tag

1.5 Confirmation and Testing

Step 1: When required, a District Mechanic and/or electrician will verify and test at the equipment, to insure that there is no electrical or mechanical energy

WARNING

Once the source has been de-energized, the system must be tested to ensure it will not operate and to verify that it is de-energized.

CAUTION

Prior to any work being performed on the system, each Authorized Employee or Primary Authorized Employee shall confirm and test (with the Operator or Pump Station Mechanic when requested) the proper lockout of each piece of equipment that needs to be LOTO for his/her work and then add his/her lock and tag to the equipment or group lockout box.

Buil de r's Exc ha

TREATMENT PLANT & PUMP STATION

The contractor and/or subcontractors should be present throughout this process since they will need to confirm and test

Step 2: On the day/night of the work, the contractor will provide the appropriate personnel (i.e., an electrician to verify the isolation of electrical energy) to go through the same verification process that District employees completed earlier

Step 3: The contractor and/or subcontractors will add their locks at the appropriate locations

Each Authorized Employee or the Primary Authorized Employee shall:

Step 4: Ensure that no personnel are exposed and verify that the energy sources have been disconnected by operating the start button or other normal operating controls, to make certain the equipment will not operate.

Step 5: Make sure all potentially hazardous stored and residual energy is relieved, disconnected, restrained, blocked, or otherwise rendered safe after the lockout or tagout devices have been put on the energy-isolating devices

Step 6: Monitor the isolation of machines and equipment that could re-accumulate stored energy to a hazardous level until:

Service or maintenance is completed, and

The possibility of re-accumulating hazardous energy doesn't exist

CAUTION

Ensure that drain line is not blocked with rags or debris

CAUTION

Return operating control(s) to neutral or off position after the test.
