UNSPSC 77101904: Chemical works or oil refinery waste site investigation

UNSPSC 77101904 Chemical works or oil refinery waste site investigation, a Commodity code, encompasses assessment, monitoring, and investigative services for contaminated sites and hazardous materials, though recent state and local solicitations show a broader scope spanning disaster debris and hazard tree removal assessment, potentially responsible party searches for contaminated properties, and herbicide chemical evaluation. State and local governments under this code procure chain of title searches, environmental site assessments, analytical testing for hazardous substances, compliance monitoring, and staff training related to contaminated site management and chemical remediation. Issuing bodies include state environmental and disaster-response departments, county parks and environmental divisions, and municipal building and planning departments. California has dominated recent activity, with the California Department of Toxic Substances Control and California Department of General Services posting multiple solicitations; Colorado counties and Georgia cities also appear as active procurers.

California Department of Toxic Substances Control issued RFP# 2627-07 on July 9, 2026 for potentially responsible party searches and chain of title searches with proposals due August 13, 2026, structured as a two-year term with unit pricing across five service categories and an estimated contract value not to exceed $950,000; the scope includes formal PRP search reports, title searches, and staff training, with performance anticipated to begin December 1, 2026 and a 5% small business preference available to California-certified firms. California Department of General Services, Procurement Division issued RFP 5269942 on August 18, 2026 for Assessment and Monitoring Services for Disaster Debris and Hazard Tree Removal statewide across five regions and three parcel-volume categories, with proposals due October 12, 2026 and a three-year term plus two optional one-year extensions organized as multi-year Master Service Agreements for mandatory use by CalOES and CalRecycle. Boulder County Parks and Open Space in Colorado issued an RFI on May 4, 2026 (responses due May 15, 2026) to identify vendors capable of evaluating whether herbicides contain PFAS or PFOS, though this non-binding information-gathering initiative does not commit to future procurement. The City of Union City, Georgia also posted plan review and inspection services in May 2026, though this solicitation falls outside the code's core contaminated-site investigation scope.
