Lost Isle Resorts 711 North Pershing Avenue, P.O. Box 844 10050 N. Foothill Blvd., Suite 200 Stockton, CA 95201-0844 Cupertino, CA 95014 REQUEST FOR A REPORT OF WASTE DISCHARGE,LOST ISLE RESORT,ACKER ISLAIVD, SAN JOAQUIN COUNTY Staff has reviewed the 4 June 2004 Lost Isle Septic System Abandonment correspondence prepared by Kjeldsen, Sinnock&Neudeck, Inc. (KSN)that describes conceptual plans to abandon the existing domestic wastewater system and replace it with a holding tank system. Staff has previously commented on the Lost Isle wastewater system on 26 October 2001 and 9 May 2002. In both letters staff requested submittal of a Report of Waste Discharge (RWD). The discharger has failed to respond to the requests. It is noted that California Water Code Section 13260(l) requires any person discharging waste to file an RWD; Section 13261 states any person failing to furnish a report or pay a fee under Section 13260 when so requested by a Regional Board is guilty of a misdemeanor and may be liable civilly in an amount which shall not exceed one thousand dollars for each day in which the violation occurs. Proposed Waste Containment System Attached to KSN's letter is a 28 May 2004 technical memorandum Reconnaissance Wastewater Storage Facilities Volume Requirements prepared by Eco:Logic,which provides an estimate of wastewater flow rates. The memo estimates peak wastewater generation rate of 15,640 gallons per day, but also states the sole water supply well on the island can only produce 7,200 gallons in a 24 hour period. To verify the wastewater flow rates the KSN letter states water suppiy measurements were to be collected in the summer of 2004. That data should be available at this time and it will be critical in determining the size of the storage facilities. Because of the volume of boat traffic on weekends, the storage facilities should be adequate to store all wastewater generated during an extended weekend such as Memorial Day or Labor Day. Special events can also generate large attendance and result in high wastewater generation rates; the holding tank design shall take such events into consideration. Relying upon a boat to pump out the holding tank and transport it to a nearby storage/transportation facility during well attended events is not acceptable because of the possibility of mechanical failure. Because there is no means to control access to the island, failure of the wastewater system would result in unacceptable discharge of waste into the surface water surrounding Lost Isle. Report of Waste Discharge By 2 December 2004, the owners/management of Lost Isle Resort shall submit a complete RWD. The RWD consists of the enclosed Form 200, a technical report that will serve as your response to Sections California Environmental Protection Agency 0 Recycled Paper
