25-E0033 Laboratory Analysis of Polycyclic Aromatic Hydrocarbons (PAHs) and Cotinine Services

This contract solicits laboratory analysis services for urine samples to measure polycyclic aromatic hydrocarbon (PAH) metabolites and cotinine as part of the CHAIRS-LA study, which evaluates health impacts from oil refinery closures in Southern California. The contractor is required to analyze up to 520 samples—20 internal Biomonitoring California samples and 500 from the CHAIRS-LA study—using established analytical methods from Yan et al. (2021) and Li et al. (2006), targeting specific PAH biomarkers including 2-NAPCA, 2-PHECA, 1-PYRCA, 4-FLUCA, 1-OH-NAP, and total cotinine via GC-MS. The work must be completed by December 31, 2026, with the contractor required to participate in monthly progress meetings and provide detailed reporting. The contract is governed by California state regulations, including the Prompt Payment Act, Public Records Act, Darfur Contracting Act, and Civil Rights protections, and mandates strict compliance with confidentiality and conflict-of-interest requirements. All bids must be submitted as a single non-fillable PDF via email by June 11, 2026, and include mandatory attachments such as the Bidder Certification Sheet, Minimum Qualifications Sheet, Cost Worksheet, insurance documentation, and references from the last seven years. The estimated contract value is $176,000, awarded to the lowest responsive and responsible bidder, with preferences applied for Small Business and Disabled Veteran Business Enterprise certifications. Payment is made on a deliverable basis, with invoices submitted monthly in arrears electronically to accounting@oehha.ca.gov in PDF or Word format, containing searchable text and fully itemized line items for each task. The final payment is contingent upon satisfactory completion of all tasks and delivery of all required data. Insurance requirements include $1 million per claim for professional liability, $1 million per occurrence for general liability, and $1 million per accident for motor vehicle coverage, with the State of California named as an additional insured. The agreement is subject to appropriation of funds and may be extended up to one year with approval. The contractor must permit state audits of records and flow down audit rights to subcontractors, and must maintain all insurance throughout the contract term, submitting updated certificates at least ten days prior to expiration to avoid material breach and potential termination.
