It is impossible that any of the referenced hazmat point-source sites could affect groundwater, soil or air over and under the property. There are no observable aboveground storage tanks (other than plastic fertilizer tanks) nor underground tank appurtenances on, or immediately surrounding the property. Therefore, it may be considered almost impossible that any tanks in this locale may affect the property because of the distances and groundwater directional flows involved. Section 9-905.12 of San Joaquin County Development Title states"Corrective Action: If the q tY P report indicates there are surface and subsurface contamination, corrective action shall be recommended in the report and concurred with by Environmental Health prior to the issuance of the building permit." It is my professional opinion that no environmental corrective action is required regarding the subject property. The ASTM E-1527-05 Document referenced on Page 2 refers to de minimus environmental conditions. De minimus conditions generally do not present a material risk to public health or to the environment and generally would not include an enforcement action if observed by the appropriate governmental agencies. De minimus conditions that were observed and include my opinions and recommendations pertain to the following: 1.) Ensure that the farmable acreage (APN 255-020-65) is a member of the San Joaquin County and Delta Water Quality Coalition(SJCDWQC), as promulgated by the Central Valley Regional Water Quality Control Board. 2.) The mobile storage tank apparently for diesel storage should be appropriately placarded(Assumed to be UN 1993). 3.) Properly dispose of waste tires,batteries, buckets,and drums. 4.)Install a threaded cap in the sounding port on top of the water well as illustrated in the Photographic Plates. § 5.2 The Appendices, found in Section 7 incorporate all of the applicable information referenced in this Report. § 5.3 See below for signature and stamp. § 5.4 Dan Schack, PE of Schack& Co. is the civil engineer for the project and is currently in the process of submitting the Tentative Parcel Map. § 5.5 As referenced above,the Appendices contain the documentation to support the applicable data and information found in this Report.
