Created in 1978, the Solid Waste Authority of Palm Beach County (Authority) has developed an “award winning” solid waste management system that includes franchised solid waste collections and the following facilities to service the residents and businesses in Palm Beach County, Florida: • North County Resource Recovery Facility (NCRRF); • Residential and Commercial Recovered Materials Processing Facility; • Five Transfer Stations; • Class I Landfill; • Class III Landfill; • Biosolids Pelletization Facility; • Ferrous Processing Facility; • Woody Waste Recycling Facility; • Composting Facility; and • Household Hazardous Waste Facility. The Authority has proactively planned and implemented its current integrated solid waste management program to ensure disposal capacity through 2021. However, even in consideration of the current economic climate, the Authority anticipates continued population growth and associated new development patterns that will significantly increase demands on its solid waste system, requiring it to reevaluate and update its planning to accommodate future growth. The NCRRF, the Authority’s refuse derived fuel waste-to-energy facility, has performed very well since its start up in 1989 processing over 13 million tons of MSW, saving valuable landfill space and efficiently producing clean renewable energy. As the NCRRF has reached the end of its first 20 year operating term, it became necessary to complete a comprehensive refurbishment to ensure its continued reliable service for a second 20 year term and beyond providing for continued disposal capacity and energy production for the Authority’s customers. Separately, the Authority also recognized that the refurbishment alone will not provide any additional disposal capacity for the County. The County’s anticipated growth necessitated that the Authority evaluate several options for long-term processing and disposal capacity, resulting in a decision to expand its WTE capacity with a new mass burn facility, the first facility of its kind to be constructed in Florida in more than a decade, reaffirming its commitment to waste-to-energy. The planned 3,000 TPD expansion will provide a total disposal capacity of 5,000 TPD generating approximately 150MW of renewable energy. The decision to proceed with the expansion was approved by the Authority’s Board in October 2008. The Authority, with its Consulting Engineer, Malcolm Pirnie, Inc., has since made significant progress in the facility’s implementation including the completion of the preliminary design, submittal of environmental permit applications, ongoing procurement of a full service vendor, issuance of revenue bonds for project financing, and commencing extensive public outreach. This paper will focus on the development of the new mass burn facility and an update of the status of activities conducted to date including, permitting, financing, vendor procurement, design, and public outreach, as well as will highlight several innovative design, procurement, permitting, and financing features of this landmark project for the Authority, such as: • Utilization of SCR technology for control of NOx emission; • Incorporation of rainwater harvesting and water reuse; • Utilization of iterative procurement process designed to obtain vendor input in a competitive environment; and • Financing approach designed to preserve alternative minimum tax benefits.
