Mr. Dave Isola • - 2 - • 24 October 2012 <br /> prepared if long-term detrimental effects in the soil and/or groundwater occur as a result of the <br /> injections. For example, if ammonium is produced, migrates to a downgradient monitoring well, <br /> and persists longer than 3 months, Ripon Farm Service could propose to establish oxidizing <br /> conditions as part of a contingency plan. <br /> On 30 August 2012, Ripon Farm Service circulated a fact sheet describing the pilot study <br /> proposal. No comments or questions were submitted. <br /> Ripon Farm Service will be conducting monitoring of the remediation project as described in the <br /> attached Groundwater Monitoring and Reporting Program. If Ripon Farm Service chooses to <br /> expand the scope of the groundwater remediation, a revised Notice of Intent shall be submitted <br /> to Central Valley Water Board staff, and a revised Notice of Applicability shall be considered by <br /> the Executive Officer. <br /> Conditions of Approval: <br /> 1. The project will be operated in accordance with the requirements contained in the General <br /> Order and in accordance with the information submitted in the Notice of Intent. The <br /> completed Notice of Intent includes the 10 May 2012 Treatability Study Work Plan, the <br /> 16 August 2012 revised Figure 10, and the 16 August 2012 letter of contingency plan <br /> commitment. <br /> 2. The required annual fee (as specified in the annual billing you will receive from the State <br /> Water Resources Control Board) shall continue to be submitted until this Notice of <br /> Applicability is officially terminated. <br /> 3. Injection of materials other than EHC®Carbon-Only into the subsurface is prohibited. <br /> 4. Failure to abide by the conditions of the General Order could result in an enforcement action <br /> as authorized by provisions of the California Water Code. <br /> 5. Ripon Farm Service will provide a contingency plan within 30 days of a request by Central <br /> Valley Water Board staff, and implemented upon staff concurrence or modification thereof <br /> within a time period deemed appropriate by Central Valley Water Board staff. <br /> 6. The Discharger shall comply with the attached Monitoring and Reporting Program, Order <br /> No. R5-2008-0149-041, and any revisions thereto as ordered by the Executive Officer. <br /> If you have any questions regarding this matter, please call Ms. Amy Terrell at (916) 464-4680. <br /> PAMELA C.
