17. INTRODUCTION Chesney Consulting has been retained by Mr. Carl Navarra of Carmelo Properties, LLC to complete the requirements of the San Joaquin County Environmental Health Department (EHD) concerning the expansion of his Carmelo Industrial Park Facility on Carmelo Avenue. The Project Description is for a Site Approval Application for the construction of Phase H to consist of"Building A" to be 3,900 s.f. and "Building B" to be 10,625 s.f., for a total of 14,525 s.f. The original Application in the year 2000 was for the approval of three buildings of 3,770 s.f., 9,100 s.f. and 5,200 s.f. for a total of 18,070 s.f.; a building area reduction of approximately 3,500 s.f During 1999 and 2000, EHD worked with the Applicants to replace the failing on-site septic system that served the Carmelo Industrial Park by requiring the installation of an updated wastewater treatment plant. A June 22, 2000 correspondence to the San Joaquin County Community Development Department stated that "EHD has worked with the Applicant to address an updated wastewater treatment plant. EHD has conditioned the plant and operation to address the additional warehouse buildings (Phase I and II). EHD will rescind its denial letter of January 31, 2000." In April 2000, I conducted a Nitrate Loading Study and Soil Suitability Study at the request of Mr. Pete Navarra, who represented the Navarra Family at that time. This April 2000 study was required by EHD to determine the soil characteristics of the proposed disposal area, and the ability of this site to accept the anticipated effluent flow volumes. The Nitrate Loading Study determined the nitrate loading potential to exceed the allowable Maximum Contaminant level. Consequently, a wastewater nitrate reduction system that would mitigate the nitrate loading from the Industrial Park's effluent was proposed and subsequently installed. The system installed in November 2000 was the EnviroServer 1200, manufactured by MicroSepTec Corporation and installed by Mr. Bernie Dietz of Dietz Irrigation. The "1200" is in reference to the capability of this Enviroserver system to process 1,200 gallons of domestic wastewater per day. This report issues my findings to fulfill the requirements of EHD for this project, which are itemized below; ❑ A complete nitrogen analysis of the influent in the existing septic tank before it is pumped (non-pressurized) to the EnviroServer 1200. ❑ A complete nitrogen analysis of the effluent after being processed by the EnviroServer 1200 before pressurized distribution to the existing filter bed. ❑ Soil sampling from prescribed intervals under the filter bed, and water analyses from the on- site well that is to serve the existing and proposed development. ❑ Calculated Average Daily Flow (ADF) volumes and projected flow volumes from the new development. ❑ Documentation that the 100% Reserve Area exists for the development of this project.
