Presentation Title: SB 1383: A Regional Approach, Orange County, CA

Presentation Summary: In order to meet the challenges of SB 1383 on a regional basis, Orange County Waste & Recycling (OCWR) has been developing compost facilities collocated at their landfills. Currently OCWR, has two active composting facilities; the Bee Canyon Greenery located at the Frank R. Bowerman Landfill and the Capistrano Greenery located at the Prima Deshecha Landfill. A third composting facility, the Valencia Greenery, located at the Olinda Alpha Landfill has been designed and is currently in construction. Each of these facilities is initially being operated as a windrow composting facility with plans to incorporate Covered Aerated Static Pile composting technology into the facilities in the future.

Due to the composting facilities being located within High Fire Hazard Zones, stringent permitting requirements of the Orange County Fire Authority include restrictions on pile spacing and dimensions. Additionally collocating the compost facilities on the landfills has created additional challenges for water supply, storm water control and composting operations, each requiring a unique solution. These composting facilities are Phase 1 of OCWR’s comprehensive vision for meeting Orange County’s organics infrastructure needs.
