Addendum No. 6 to Final EIR 588 - RELOOC Strategic Plan Olinda Alpha Landfill Implementation - Revision to SWFP to Update Landfill Closure Date

This Addendum to Final EIR 588 outlines the implementation of the Final Closure and Post-Closure Maintenance Plan for the Olinda Alpha Landfill in Brea, California, focusing on the full sequence of closure activities including the cessation of waste disposal and a substantial reduction in facility tonnage relative to baseline conditions. The plan anticipates a five-year post-closure settlement period and involves the delivery and installation of engineered final cover materials, construction activities that include temporary increases in equipment and truck traffic, and the long-term maintenance of stormwater and landfill gas management systems. All activities remain within the previously approved landfill footprint without increasing permitted tonnage or total disposal capacity, and the existing material recovery and composting operations will continue, either integrated into landfill operations or under a separate Solid Waste Facility Permit to be secured from regulatory agencies. The plan is being developed to establish a financially sound and permanently viable funding structure to support closure and ongoing maintenance in compliance with environmental regulations. The addendum serves as a strategic update to the Solid Waste Facility Permit to reflect the revised landfill closure timeline and is part of a broader regulatory and environmental compliance process initiated under CEQA. The project is managed by Orange County Waste & Recycling, with Leila Barker, CEQA/Habitat Manager, serving as the primary point of contact. The work is geographically confined to the Brea location with a ZIP code of 92823, and the solicitation was posted on July 10, 2026, under NAICS code 562212, which pertains to landfill excavation and closure services. While specific contract clauses, cost details, performance periods, evaluation criteria, or delivery schedules are not available in the provided documentation, the intent is clearly aligned with ensuring environmental integrity and regulatory adherence throughout the closure and indefinite post-closure phases, with funding mechanisms designed to sustain operations as required by applicable agencies.
