Request for Proposal 2526-09 Statewide Site Monitoring Services

The California Department of Toxic Substances Control (DTSC) is issuing Request for Proposal 2526-09 for Statewide Site Monitoring Services, a professional services procurement seeking qualified firms to provide comprehensive monitoring of 400 to 1,000 DTSC sites throughout California that have institutional controls in place. The contractor must supply all necessary personnel, materials, supplies, facilities, and equipment to conduct extensive surveillance of multiple information sources including call-before-you-dig services, building permits, dredging permits, real estate listings, CEQA projects, water well permits, and property transfer records. Key deliverables include establishing electronic alerts to DTSC project staff in advance of potentially harmful activities, maintaining active hyperlinks to institutional controls and EnviroStor public profiles, and monitoring approximately 450 initial sites within 90 days of contract commencement, with setup capability for new sites within two weeks. The contractor must provide fully loaded monthly rates for seven monitoring subtasks ranging from $5 to $400 per site, plus a $400 per-site activation fee for Task 1. Evaluation will employ a pass/fail assessment of minimum qualifications followed by a 100-point technical scoring system with a minimum passing score of 75 points; only proposers meeting this threshold will have sealed cost proposals opened. The deadline for written questions is May 15, 2026, with DTSC responses posted by May 26, 2026. Proposals are due June 2, 2026, at 3:00 p.m. Pacific Time, with notice of intent to award anticipated for June 12, 2026, and contract performance beginning July 1, 2026, for a three-year term.

The procurement carries a minimum Disabled Veteran Business Enterprise (DVBE) participation requirement of 3 percent unless an exception is granted in writing by DTSC. The contractor must maintain general liability insurance with minimum limits of $1,000,000 per occurrence and in aggregate, as well as statutory workers' compensation coverage with employer's liability limits of $1,000,000. The RFP does not identify any incumbent vendors or current contractors, suggesting this represents a new contract award. The scope encompasses approximately 600 contaminated sites drawn from the EnviroStor database representing diverse facility types including military installations, manufacturing plants, refineries, chemical processing facilities, rail yards, mining properties, and commercial developments across multiple California counties. The total contract value shall not exceed $655,000, with monthly invoicing upon satisfactory completion of work and receipt of proper invoices submitted in duplicate. The baseline monitoring matrix identifies approximately 500 sites requiring immediate monitoring, with additional sites subject to future enrollment based on DTSC needs and site-specific conditions.
