Mr. Jack Verderame - 4 - 10 March 2010 <br />Pond Rehabilitation after Wastewater Discharge <br />To rehabilitate the pond for unrestricted use as a golf course water feature, the Discharger <br />shall completely drain the pond of water (either by infiltration or through the leachfield), remove <br />all sludge present in the pond (and dispose of at a permitted landfill), and disc the bottom of <br />the pond. The Discharger shall provide written notification to the Central Valley Water Board <br />that the work is completed. Ten days after the notification, the Discharger may begin <br />preparing the pond for use as a golf course water feature. Until the rehabilitation is complete, <br />fencing and signs must limit public access to the area. <br />Long Term Subsurface Wastewater Discharge <br />The Discharger plans to operate subsurface leachlines to dispose of treated wastewater. The <br />elements of design for the subsurface system are presented in the July 2408 RWD, prepared <br />by Nolte Associates, Inc. Although the RWD states the existing treatment system is not <br />required for the subsurface disposal, the Central Valley Water Board is requiring continued <br />treatment of wastewater by the existing package treatment plant because of the potential for <br />formaldehyde to be present in the wastewater. <br />This NOA authorizes a flow rate of 20,000 gpd, which is the maximum flow rate allowed by the <br />WQO. The Discharger may apply for a higher flow rate but will need to obtain site-specific <br />WDRs for such a discharge. The RWD provided leachfield disposal capacity calculations that <br />demonstrated adequate disposal capacity for 44,800 gpd. <br />Groundwater is approximately 35 feet below ground level at the site. Based on the level of <br />wastewater treatment and the low wastewater discharge.rate, the discharge poses little threat <br />to, groundwater quality if the facility is operated and maintained as described herein. <br />Therefore, groundwater monitoring is not required at this time. <br />MONITORING AND REPORTING PROGRAM <br />The Discharger shall comply with the monitoring and reporting requirements prescribed in <br />Monitoring and Reporting Program (MRP) No. R5 -2010-R5061, which replaces MRP No. <br />97-10-DWQ for this facility. The requirement to begin monitoring for MRP No. R5 -2010-R5061 <br />is effective upon beginning the discharge to the golf course pond. <br />GENERAL INFORMATION AND REQUIREMENTS <br />The Discharger shall comply with WQO No. 97-10-DWQ. WQO Section B describes varying <br />requirements based on the type of treatment and/or disposal method. Because the treatment <br />system will transition from discharge to the golf course pond to subsurface discharge, certain <br />requirements listed in Section B will apply only while surface or subsurface discharge is <br />occurring-, in addition, some of the requirements will apply at all times. <br />The requirements from WQO Section B that will change with the transition are listed in the <br />table below: <br />Requirements <br />Section No. <br />Applicable <br />All Small Domestic Systems <br />B.1.a,b,c,d <br />At all times <br />Septic Systems <br />B.2.c <br />At all times <br />Activated Sludge Systems <br />B.3.b,c' <br />At all times <br />Aerated Pond Systems <br />BA <br />When discharging to pond <br />
