The <br />1912 Sanborn Fire Insurance Map also identifies a Southern Pacific Railroad freight depot and <br />small office at the west end of the subject property near Charnelton Street and 4th Avenue. <br />The pump house, the freight depot building, and the small office are not present on the 1968 <br />Sanborn Fire Insurance Map. The 1968 Sanborn Fire Insurance Map identifies the building on <br />the east contiguous property as a truck repair facility. <br />Based upon the review of government agency files, historical Sanborn Fire Insurance Maps, <br />and the site visit, the following potential environmental issues were identified: <br />1. Chemical trespass onto the subject property from the Pearl Street property at <br />408 Pearl Street. The agency files dv not include any data for the western <br />wells and current data is not available for the eastern monitoring wells. In order <br />to assess the current groundwater conditions beneath and adjacent to the <br />subject property, groundwater samples for laboratory analysis should be <br />collected from monitoring wells MW-1, MW-2, MW-3, MW-4, MW-B-9, MW-5, <br />MW-6, MW~7, and MW-8. The western wells will need to be located prior to <br />sample collection. The groundwater samples will be analyzed for VOCs using <br />Environmental Protection Agency (EPA) Method 8260. <br />2. Subsurface conditions in the vicinity of the potential former heating oil UST at <br />the main train station building should be investigated by the installation of <br />macro core push probes completed with a truck mounted Model 5400 <br />Geoprobe~ and the collection of soil and groundwater samples for laboratory <br />analysis. The soil samples should be analyzed for total petroleum hydrocarbon <br />(TPH} identification using Northwest Methods NWTPH-HCID. Based upon the <br />results of the NWTPH-HCID analysis, soil samples will be quantified by <br />Northwest Method NWTPH-Gx (gasoline) and/or NWTPH-Dx Idiesel or tube oil) <br />as required. Groundwater samples will be analyzed for VOCs using iwPA <br />Method 8260 and for polynuclear aromatic hydrocarbon (PAH) compounds <br />using DEQ Method GC/MS SIM (modified J=PA Method 82701. <br />3. The presence of a possible heating oil UST at the tool house building will be <br />investigated by performing a magnetic survey to identify near surface and <br />buried ferrous metal objects (i.e., fill caps, UST, etc.1.
