History

  • 1961-1964 County leased the property from The Irvine Company (TIC) and operated it as refuse disposal station.
  • 1964 County ceased disposal operations, closed the site and surrendered the leases back to the property owner. The property owner, TIC, developed and operated majority of the site as the Rancho San Joaquin Golf Course.
  • 1988 County completed and submitted an air Solid Waste Assessment Test (SWAT) questionnaire.
  • 1992 A water SWAT was conducted and report submitted to the Regional Water Quality Control Board (RWQCB). The property was conveyed from TIC to National Golf Partners (NGP), who continued the golf course operations.
  • 2000 The site was not included in the County’s Closed Landfill Environmental Assessment and Response (CLEAR) project. County completed a work plan for the CLEAR site investigation and submitted it to the Local Enforcement Agency (LEA), but field activities were not initiated due to owner’s denial of access to the site. The RWQCB issued a requirement for NGP to investigate surface settlement and potential landfill gas (LFG) migration or surface emissions.
  • 2003 LEA issued a Notice and Order (N&O) for installation of LFG monitoring probes and a structure survey of nearby residences. The N&O was amended to extend the time allowed for completion of a long-term LFG remediation plan, the design of a LFG collection and control system, and a site maintenance plan.
  • 2004 The RWQCB issued a Notice to Comply (NTC) requiring reduction of methane emissions at the site, and requested County’s input on the site maintenance plan submitted by NGP. The plan later became the Cover Maintenance Plan and was approved by the RWQCB. NGP’s consultant issued a Landfill Gas Assessment Finding Report for site. County notified the RWQCB of their concerns that the proposed LFG system would not successfully mitigate groundwater impacts at site. NGP’s consultant began work on a LFG Corrective Action Plan (CAP).
  • 2005 LFG Corrective Action Plan (CAP) for site was conditionally approved by the LEA. NGP’s consultant began design of the LFG collection and control system.
  • 2006 LFG collection and control system was constructed.
  • 2007 LFG collection and control system operated by NGP’s consultant.
  • 2008 LFG collection and control system operation, maintenance, reporting responsibility and ownership transferred to County pursuant to a Settlement Agreement with NGP.
  • 2009 County constructed an extension to the LFG system to control LFG migration on the northerly site border.
  • 2010 County conducted indoor air monitoring at the Shir Ha Ma’alot Synagogue. No methane was detected inside the building above background levels. County submitted the Long Term Monitoring and Operational P (LTMOP) and the Construction Completion Report for Landfill Gas Extraction System & Treatment to the LEA.
  • 2011 County installed two LFG collection wells to improve the collection system.  On April 20, the LEA terminated the Notice and Order issued to NGP Realty Sub L.P. in March 2009 for migration of landfill gas above the regulatory compliance levels.
  • 2012 Two additional LFG probes were installed at the site. The site owner is working with RWQCB-SA to correct drainage issues at the site. Drainage improvements will be completed in phases as approved by RWQCB-SA.
