Mr. Robert Granberg • - 5 - . 25 May 2010 Dewatered Groundwater Application Plan Groundwater will be discharged to an on-site tank to settle solids; then it will be applied to land application areas. The application will proceed as follows: • The Woody's on the River parcel (436 acres) will be used as the primary land application site; the Suprenant parcel (123 acres) will be a backup application site. If additional land is required, then a portion of the 436 acres (a cornfield) held in reserve will be used. • Dewatered groundwater will be transmitted via a 12-inch diameter pipeline. The primary discharge location is the northeast corner of the Woody's on the River property. From that location the water will follow the natural flow of the land through the swales and ponds; the water will eventually overflow from the swales and ponds, flooding the entire acreage inside the dikes. All outfall structures leaving the property will be blocked to contain all water within the existing dikes. • If the Woody's on the River parcel fills to the point that no additional water can be applied, the discharge will be redirected to the Suprenant parcel using the same application method. If needed, the water may be used to irrigate the corn growing in the reserved 70 acres of Woody's on the River (this is a duck bait crop only, and is not intended for human consumption). MONITORING AND REPORTING PROGRAM The Discharger shall comply with the monitoring and reporting requirements prescribed in Monitoring and Reporting Program (MRP) No. 2003-0003-DWQ-R5010, which replaces the MRP attached to State Water Board Order No. 2003-0003-DWQ for this facility. The requirement to begin monitoring for MRP No. 2003-0003-DWQ-R5010 is effective upon beginning the dewatering activities that will result in application of dewatered groundwater to land. Groundwater that will be disposed of in the City of Stockton collection system is not subject to the monitoring requirements of this NOA. GENERAL INFORMATION AND REQUIREMENTS The Discharger shall comply with WQO No. 2003-0003-DWQ. The maximum average flow rate to the LAAs is hereby limited to 2.3 Mgpd. (The monthly average shall be calculated by dividing the total flow for the month by the number of days in the month). If groundwater elevation monitoring (as described in the attached MRP R5-2010-R5010) indicates an effective hydraulic barrier does not exist (as defined by a groundwater flow direction to the west in wells in close proximity to the western side of the barrier), the Discharger shall notify the Central Valley Water Board as soon as practicable and shall provide written notification within 24-hours. The notification shall include a plan to reestablish hydraulic control at the infiltration trench. Please review this Notice of Applicability carefully to ensure that it completely and accurately reflects the proposed discharge. If the discharge violates the terms or conditions above, the Central Valley Water Board may take enforcement action, including assessment of administrative civil liability. If the method of extracted groundwater changes from that described in the NOI and additional information, you must submit a new NO[.
