B. Drawings including, but not limited to, Civil, Mechanical, Structural, Electrical, & Instrumentation.

C. “Hazardous Materials Survey Report, Enhanced Treatment and Site Upgrade Program

– Phase 1A Project, Covered Storage Structure, Alvarado Wastewater Treatment Plant, 5072 Benson Rd. Union City, CA” prepared by Vista Environmental Consulting and dated September 18, 2024.

1.2 SUMMARY

A. This Section includes the following:

1. A general description of the hazardous materials related work associated with this project and including information regarding known and assumed (presumed) existing hazardous materials likely to be impacted and abated by this project.

2. Requirements and procedures related to lead-related selective demolition work.

3. Requirements for removal and disposal of PCB ballasts and universal waste items prior to demolition.

B. Existing Hazardous Materials Conditions.

1. The Contractor shall take into account the known and presumed existing lead-containing materials, and other hazardous materials known or assumed present based on existing survey reports provided by the Union Sanitary District and the contract documents.

2. The Contractor’s work requires removal of hazardous materials such as PCBs, universal wastes (UW), and the disturbance of lead containing paints and coatings during selective demolition structures, components and equipment. All associated costs of hazardous material remediation, lead-related construction work, worker protection, clean up and disposal resulting wastes are to be included in the bid price submitted.

3. Hazardous Materials known or assumed to be present in building to be demolished and areas to be disturbed by work of this project include:

Buil de r's Exc ha

CAMPUS SOLAR FACILITIES 02 81 00-2 OCTOBER 2025

a. Lead-Containing Paints (LCP) - All paints including untested paints shall be considered lead-containing paint (LCP) with detectable levels of lead and for pre-1978 construction untested paints shall be considered to be lead-based paint (LBP) unless proven otherwise. Existing survey results by XRF testing are as follows:

1) Covered Storage Structure:

a) LBP: None detected;

b) LCP: E xt erior doors and bollards tested were 0.01 mg/cm2 lead.

b. Polychlorinated Biphenyl (PCB): Fluorescent light fixtures with approximately 39 assumed PCB ballasts are present in the covered storage structure will require the Contractor’s inspection of each removed fixture’s ballast for labeling or marking regarding date of manufacture and/or PCB content.

c. Universal Waste (UW) Items: Approximately 78 fluorescent light tubes are present total all project areas. In addition, a total of 2 batteries for emergency lights and exit signs are present in the project area and also shall be considered to be UW items for disposal

d. Silica (crystalline quartz): This project involves demolishing, saw cutting, coring, and other activities involving concrete which can generate airborne levels of crystalline silica.

e. Review the referenced hazardous materials survey report for more specific information regarding hazardous materials and substances present at this site and review the project drawings for reference information regarding other site conditions for known or suspect hazardous materials that may be disturbed or demolished. All quantities of each known or suspect hazardous material are to be field verified by the Contractor prior to submitting a bid.

C. Summary of Hazardous Materials-Related Work

1. The work of this project involves mitigating the identified hazardous materials likely to be disturbed during selected structural demolition and other construction activities; removal of other hazardous materials including the removal of all impacted assumed PCB lighting ballasts; removal of all impacted Universal Waste Items; demolishing structural and equipment components that contain lead-containing paints; and conducting demolition and other construction operations involving structural concrete building components that contain crystalline silica.

2. The Contractor shall review any available as-built plans and all project demolition and construction plans for the building and infrastructure associated with this project and shall coordinate the hazardous materials work with those plans and the information they provide. This project will require Contractor personnel qualified to conduct lead-related construction/demolition work; and concrete work that involves crystalline silica dust generation. The project also requires removal and proper disposal of PCB ballasts, and Universal Wastes. Review the hazardous

Buil de r's Exc ha

CAMPUS SOLAR FACILITIES 02 81 00-3 OCTOBER 2025

material survey report and project drawings in detail to verify the location and approximate extent of hazardous materials-impacted work and include the cost of that work in the project bid price.

3. All hazardous materials and substance disturbance and removal work shall be undertaken utilizing the proper lead and hazardous materials work practices, protective measures, controls, waste stream profiling and testing, and waste disposal of properly characterized removed materials as required to support this project.

a. Removed lead paint chips and PCB ballasts are to be disposed of as hazardous waste;

b. Universal Wastes shall be disposed of as hazardous waste or recycled by a permitted TSD.

4. The Contractor’s work scope all required lead-related protective measures for Cal/OSHA and Cal/EPA compliance associated with demolition and other finish disturbing activities of this project.

5. Conduct removal of all lead-containing paints and coating disturbance, and all concrete related work in compliance with federal and state (Cal/OSHA) worker protection rules and this section.

6. Clean up all surfaces affected by demolition so as to leave each work area free of visible lead dust and debris and leave the project site with lead levels below all recognized hazard thresholds at the end of each day’s work shift and prior to any site preparation for new construction.

7. The Contractor shall treat all “assumed” hazardous materials as actual confirmed hazardous materials for bidding purposes. Assumed PCB ballasts will be verified to be PCB or non-PCB by the Contractor’s visual inspection as part of the fixture removal process. During Construction, Assumed ACM water proofing on subsurface concrete can be tested for asbestos content once exposed at each separate structure to be demolished via the Contract’s request for information (RFI) process but must be bid as ACM.

D. Contractor’s Observation Service

1. The Contractor must retain the services of a qualified industrial hygiene consultant certified for lead consulting in the State of California, for the purpose of monitoring the day-to-day operations of the Contractor on an ongoing or as needed basis to ensure each work area is completed before it is released for unrestricted access.

This consultant shall have authority to review the Contractor’s pre-start, progress, and close out submittals; inspect containments, observe Contractor’s procedural compliance, review Work Areas for completion, and conduct clearance inspection and testing with regard to hazardous material removals and lead-related demolition.
