  Requiring Pacific Gas And Electric Company to Clean Up and Abate Waste Discharges of Total And Hexavalent Chromium to the Groundwaters of the Mojave Hydrologic Unit
• At its November 4, 2015 meeting, the Lahontan Water Board issued a comprehensive Cleanup and Abatement Order against Pacific Gas and Electric Company to continue its cleanup of chromium-contaminated groundwater in Hinkley, Calif.  The Water Board’s meeting agenda page includes comment letters, presentations and audio files for agenda item 6 (the proposed PG&E CAO).

The proposed CAO directs PG&E to continue and improve cleanup actions to remediate chromium-contaminated groundwater; define the chromium plume where it remains incompletely defined; sets plume capture requirements; and sets deadlines to meet interim cleanup targets.  A monitoring and reporting program is included.  Click on the links below to view the CAO and attachments.

• Lahontan Water Board Prosecution Team and PG&E Consensus Language for the Cleanup and Abatement Order
  
  The below documents are provided for your information. This is not a request for comments at this time.
  • Advisory Team Request to Parties for Clarification of Consensus Language (September 3, 2015)
    • Response to Advisory Team Request from Parties

The Lahontan Water Board Prosecution Team and PG&E provided the below documents which contain proposed consensus language for the proposed Cleanup and Abatement Order (CAO) in response to the Executive Officer's letter dated June 25, 2015. The June 25th letter provided the parties additional time to develop in consensus proposed changes to the original proposed CAO. The Water Board's advisors will review the proposed consensus language and provide a revised CAO draft for the public’s review in August, which may incorporate all or some of the proposed consensus language and other changes based upon comments previously received and ideas generated at the May workshop. A workshop on the new draft will be held at the September 16-17, 2015 Board meeting in Barstow. After a public comment period on the new draft CAO, the Water Board will plan to consider adoption of a final CAO at its November 4-5, 2015 Board meeting, which will also be held in Barstow. A final schedule, including the comment period on the revised draft, will be released with the revised draft in August.

The Lahontan Water Board is not requesting comments on the below documents, but welcomes your comments on the revised draft CAO to be issued in August.
