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