Executive Summary:
The Sonoma County Public Infrastructure Department (SPI) is requesting the Board approve and authorize the Director of Sonoma County Public Infrastructure to execute six Professional Services Agreements to provide hazardous waste removal and disposal services on an as-needed basis. The proposed agreements will be executed with the following qualified firms: Advanced Chemical Transport, LLC; Alpha Petroleum Transport Inc. II; Ancon Marine; Environmental Logistics Inc.; Kleen Solution Environmental, Inc.; and Patriot Environmental Services, Inc. Each agreement is for an initial term of three years with the option of two, 1-year no-cost extensions. The aggregate not-to -exceed value for all six agreements is $15,000,000.
If approved, the proposed agreements will ensure the County can respond efficiently to hazardous material incidents and maintain compliance with State and Federal regulations. Services provided under the agreements will include the identification, packaging, transportation, and lawful disposal of hazardous materials encountered during County operations, including roadway maintenance, transit operations, and illegal dumping response.
Discussion:
Sonoma County Public Infrastructure (SPI) maintains approximately 1,369 miles of roadway in unincorporated Sonoma County and operates Sonoma County Transit services. During routine operations, SPI frequently encounters hazardous materials resulting from homeless encampments, vehicle accidents, illegal dumping, maintenance activities, and spills within the public right-of-way or at County facilities. These materials present potential risks to public health, the environment, and transportation operations.
SPI staff are not certified to identify, handle, transport, or dispose of hazardous materials in accordance with State and Federal regulations therefore, the County relies on qualified hazardous material contractors to perform these services safely and lawfully. The county currently has blanket purchase orders (BPOs) for various categories of hazardous waste removal; however, these existing agreements do not cover the full range of services required to meet operational needs. As a result, SPI has also used agreements administered by the Integrated Waste Division to fill critical service gaps. These agreements have provided essential support but are scheduled to expire in 2026 and will no longer be available for SPI use at that time.
To ensure continuity of timely and compliant hazardous waste response services, SPI issued a Request for Proposals (RFP) on November 21, 2025, to solicit proposals from qualified firms capable of providing hazardous waste removal and disposal services on an as-needed basis. Six responses were received: Advanced Chemical Transport, LLC; Alpha Petroleum Transport Inc. II; Ancon Marine; Environmental Logistics Inc.; Kleen Solution Environmental, Inc.; and Patriot Environmental Services, Inc.
The RFP requested services including:
• Identification, packaging, transportation, and disposal of hazardous waste
• Removal and disposal of materials generated at County facilities
• Cleanup of hazardous waste from illegal dumping or spill sites
• 24-hour emergency response for hazardous material incidents
• Waste profiling, documentation, and regulatory compliance
• Training for County staff regarding hazardous material handling and storage
These services address a wide range of materials that may be encountered during County operations, including paints, oils, automotive fluids, batteries, electronic waste, solvents, chemicals, biohazards, illegally dumped waste, and other regulated hazardous materials.
SPI is requesting Board approval of six agreements for as-needed hazardous waste removal and disposal services and. Each agreement will have an initial term of three years, with options for up to two one-year, no-cost extensions. The aggregate not-to-exceed amount for all six agreements is $15,000,000.
If approved, the agreements will be utilized on an as-needed basis, authorizing work through task orders. Each task order will define the specific scope of work, schedule, and cost for the services requested. The proposed agreements have no guaranteed minimum amounts and will be used based on departmental and County needs. Establishing these agreements will ensure the County can respond promptly to hazardous materials incidents, maintain compliance with applicable environmental regulations, and protect public health and safety.

Narrative Explanation of Fiscal Impacts:
Appropriations for costs to be incurred under these Agreements will be available through Department Adopted Budgets and utilized only when the services are deemed necessary by Department management. Departments will be billed directly for services rendered. Countywide costs for hazardous waste removal and related services have averaged $1,200,000 annually. The contract authority is based on the historical average annual cost, with additional capacity included to account for expanded use across all County departments, increased activity related to encampment cleanups and illegal dumping, and anticipated inflationary impacts. Establishing a higher cap provides the flexibility to address potential increases in need, including more severe or unforeseen events. The new agreements are structured with a five-year term, and the cap represents a maximum allowable amount, with minimum spending requirement.
