RECOMMENDATION(S)
Recommendation
Adopt Resolution providing the City of Rialto and the State Department of Conservation with a Pledge of Revenue, in the amount of $5,179,131 for calendar year 2026, for the reclamation of mined lands at Mid-Valley Sanitary Landfill in compliance with the State Mining and Reclamation Act, Public Resources Code section 2773.1.
(Presenter: Noel Castillo, Director, 387-7906)
Body
COUNTY AND CHIEF EXECUTIVE OFFICER GOALS & OBJECTIVES
Provide for the Safety, Health and Social Service Needs of County Residents.
FINANCIAL IMPACT
Approval of this item will not result in the use of Discretionary General Funding (Net County Cost) as the Department of Public Works - Solid Waste Management Division (SWMD) is financed by fee revenue. SWMD establishes fees that are charged to the public and other agencies for utilization of the County’s Waste Disposal System. The Resolution pledges future tipping fee revenue as an assurance of funds for reclamation. Sufficient appropriation and revenue will be included in future recommended budgets to accommodate the Pledge of Revenue.
BACKGROUND INFORMATION
The County's Mid-Valley Sanitary Landfill (MVSL) is located in the City of Rialto, northwest of the intersection of Alder Avenue and State Route 210. The site occupies approximately 448 acres of which 408 are permitted for refuse disposal.
The excavation activities associated with the expanded MVSL are classified as mining under the State Surface Mining and Reclamation Act (SMARA). In accordance with SMARA requirements, a financial assurance mechanism must be established by the mine operator before operations commence. This mechanism ensures that environmental, health, and safety obligations will be fulfilled in the event of operator default.
The standard types of financial assurance mechanisms for governmental operators are listed in California Code of Regulations, Title 14, Section 3803, as surety bonds, irrevocable letters of credit, trust funds, pledges of revenue, or a budget set-aside. The financial assurance is payable to the Lead Agency, in this case, the City of Rialto, jointly with the administering regulatory agency, the State Department of Conservation.
SWMD, as the mine operator, may choose the financial assurance mechanism and is proposing to establish a pledge of revenue for the MVSL project as it is the most cost effective and efficient mechanism. A pledge of revenue is a financial assurance mechanism by which a governmental entity proposes to make specific, identified future revenue available to perform reclamation. The financial assurance will remain in place until the State Department of Conservation determines that reclamation has been completed and no further assurances are needed. Once that is done, the financial assurance, in this case the pledge of revenue, will be released. A pledge of revenue requires adoption of a resolution under Code of Regulations, Title 14, Section 3806.1. Similar assurances have been approved by the Board of Supervisors for flood control-related borrow sites.
The $5,179,131 Pledge of Revenue amount for MVSL is based on the cost estimate for reclaiming the remaining site area in the event it is not used for landfilling. The City of Rialto advised that the financial assurance is based on the calendar year. This Pledge of Revenue amount is for the calendar year 2026. Reclamation activities include, but are not limited to, removal of mining infrastructure, revegetation, and establishment of a perimeter sight barrier in compliance with the site’s Development Agreement. The cost estimate can be revised annually as landfill development and mining operations progress.
The establishment of this Pledge of Revenue has been reviewed by the Department of Public Works, Environmental Management Division (EMD), for compliance with the California Environmental Quality Act (CEQA). EMD concluded that the resolution and Pledge of Revenue do not constitute a project under CEQA guidelines, and no CEQA actions are required.
This Resolution and Pledge of Revenue align with the County and the Chief Executive Officer’s goals and objectives of providing for the safety, health and social service needs of County Residents by providing landfill services in compliance with SMARA and the Development Agreement between the City of Rialto and the County and allows continued progress of the landfill expansion to provide necessary disposal services.
