  • 2016 Port of Stockton’s Dock 20 Aeration Facility Operations and Cost Summary

  • 2016 Amended Aeration Agreement & 2015 Operations and Cost Summary
    An amended aeration agreement was executed in April 2016 that provides funding for the operations and maintenance of the Port of Stockton's Dock 20 Aeration Facility. Also, the Operations and Cost Summary for 2015 have been completed and posted.

  • Staff Report and Resolution R5-2015-0008
    The Control Program required an evaluation of the allocations and implementation provisions once studies in the San Joaquin River watershed were completed. Staff reviewed the results of the studies and developed a Staff Report with recommendations for future actions to address the DO impairment.

    The Staff Report was presented to the Regional Board during their February 5-6, 2015 Board meeting. Staff recommended that the allocations not be revised and the existing Control Program be continued. The Board concurred with staff's recommendation and approved Resolution R5-2015-0008. In addition, the Board strongly supported the continued use of aeration in the channel and staff's efforts to increase the number of stakeholders participating in funding the long-term operation and maintenance of the aeration facility.
