t hKLEIN FELDER EXECUTIVE SUMMARY This is a report of Kleinfelder's Limited Phase II Environmental Site Assessment conducted at the proposed Tracy Multimodal Station (portion of APN: 235-150-16) located on the SEC of Central Avenue/Sixth Street in Tracy, California(See Plate 1). Mr. Harry Montgomery of The San Joaquin Regional Rail Commission, retained Kleinfelder to conduct the assessment in accordance with a Consultant Services Agreement, No. A-97-011, entitled "Tracy Multimodal Station Hazardous Materials and Geotechnical Testing", dated April 3, 1997. ' Espana Geotechnical Consultants conducted a Phase I Environmental Assessment of the subject site in January and February 1996. Their report entitled"Phase I Hazardous Materials Study, Tracy Multimodal Station, City of Tracy, California," dated March 1996, included the following recommendations related to the subject site: • Soil sampling and analysis for petroleum hydrocarbons, lead, heavy metals, and volatile/semi- volatile organics adjacent to the southern boundary of the site. • Groundwater sampling and monitoring along the southern boundary of the site • Soil sampling and analysis for hydrocarbons and volatile/semi-volatile organics along the northwest property boundary. In May 1997, Kleinfelder submitted a workplan to San Joaquin County Public Health Services Department Environmental Health Division (PHS/EHD), based on Espana's Phase I report and Kleinfelder's contract with the San Joaquin Regional Rail Commission. However, PHS/EHD did not grant permit or workplan approval until a copy of the "right-of-entry" agreement for the Phase II Environmental Site Assessment was provided to their office. A copy of the right-of-entry agreement was supplied by the San Joaquin Regional Rail Commission(SJRRC) to Kleinfelder and subsequently PHS/EHD in February 1998. Based on the submittal, permit and workplan approval was given. During February and March 1998, Kleinfelder conducted the Limited Phase II Environmental Site Assessment of the subject site. As a part of the field assessment, a total of nine exploratory soil borings were drilled, six in the areas of environmental concerns (B1/HP-1 through B6/HP-6) and ' three for geotechnical purposes (B7 through B9). Boring B7 was used as for both environmental and geotechnical purposes. Borings B1/HP-1 through B3/HP-3 were located along the northern border of the site adjacent to a Santa Fe Pacific petroleum pipeline. Borings B4/HP-4 through B7 were located along the southern border of the site and in the southwestern portion of the site, adjacent to the Southern Pacific Transportation easement and the proposed station building (See Plate 2). For purposes of this report, only the borings associated with environmental concerns (B1/HP-1 through B7) will be addressed, a separate report will address the geotechnical findings. 1 Page I of 15 20-4054-OI.E01/2018R299 May 8, 1998 © 1998,Kleinfelder,Inc.
