Capitol Ave. Lodi, CA 95242 On September 28, 2009, the San Joaquin County Environmental Health Department (EHD) participated in a telephone conference with your consultant, Mr. Robert Marty and Mr. Timothy Cuellar of Advanced GeoEnviron mental Inc., and your attorney, Mr. Scott Rishwain to discuss the destruction of five monitoring wells that still have not been properly destroyed. The Central Valley Regional Water Quality Control Board (CVRWQCB) required destruction of the monitoring wells installed to investigate the above subject site prior to their issuing a "No Further Action Required" letter for the above subject site. In May 2008 the EHD issued permits for destruction of the monitoring wells. The five wells (MW-8, 9, 10, 11, and 13) were constructed with continuous multichannel tubing (CMT) casing. Destruction of these wells is problematic because of the small chamber design. Different methods of destruction have been attempted and an acceptable, reliable method has not been found. Since encountering a problem with the destruction of MW-13, there has been no progress in properly destroying these last five wells. By San Joaquin County Well Standards definition these wells are abandoned and according to Section 6.1 of the Well Standards they must be destroyed. It was agreed during the telephone conference that a schedule would be submitted to the EHD within 30 days. The schedule will include the date the remaining five wells will be properly destroyed and a plan describing the method and materials to be used to complete the destruction. It was also discussed that if the destructions are not completed within 45 days of the date of this correspondence, a referral for formal enforcement action by the San Joaquin County District Attorneys' Office may be made. The EHD well destruction permits issued in May 2008 for this work have expired and new Well Permit Application Forms and $60 permit fee per application must be submitted. The remaining wells are located on four different parcels so four applications and four $60 fees are required. Please include private property access agreements and a copy of the San Joaquin County Public Works encroachment permit with the applications.
