MATRIX <br /> 1 GEO <br /> 3.2.1 Historical Site Map and Aerial Photographs <br /> A historical site map of the former pump station is included in Appendix D and shown on <br /> Figure 2. Above-grade structures of the former pump station located within the Arcos property <br /> included a boiler house, a pump house, a heater house, a sump, an incinerator, a rubbish pit, <br /> and three bulk storage tanks with secondary containment structures. The capacities of the <br /> individual bulk storage tanks were reportedly 7,140, 7,420, and 20,204 barrels. Each of the <br /> bulk storage tanks was connected to the heater house via a"suction' line. The site map <br /> iindicates three pipelines entering the pump station from the east comer of the current Arcos <br /> 1.. <br /> property, conveying flows to the heater house, and two pipelines exiting to the north across the <br /> current Bellini property. Cottages(likely residences for pump station employees) were located <br /> -�: along the western portion of the site. <br /> Historical aerial photographs of the site were obtained and reviewed to assess site use after the <br /> pump station and to identify areas of potential environmental concerns. A review of these <br /> ` aerial photographs (included in Appendix D) is described below. <br /> • August 1937 aerial photograph-Site features appear similar to those shown on the <br /> ifl historical site map. <br /> • March 1950 aerial photograph-The three bulk storage tanks and the cottages along <br /> -� the western portion of the site appear to have been removed from the site. <br /> • July 1957 aerial photograph-New buildings appear to have been constructed west <br /> of the pump house area within the current Bellini property. <br /> 1 • June 1963 aerial photograph-Additional new buildings appear to have been <br /> constructed west of the pump house area within the current Bellini property. A <br /> majority of the area of the current Arcos property,except for the western portion, <br /> appears to have been planted as an orchard. <br /> • May 1968 aerial photograph-Site features appear similar to those shown on the <br /> 1963 aerial photograph,except that the orchard appears more established. <br /> • July 1983 aerial photograph-Most of the buildings located within the current <br /> Bellini property and the orchard within the current Arcos property appear to have <br /> been removed. The southern portion of the current Arcos property appears to be <br /> used for crops planted in long rectangular patches. Scattered debris and small <br /> J aboveground structures appear to be located within the northern portion of the <br /> current Arcos property. A new building appears to have been constructed near the <br /> west comer of the current Arcos property. <br /> J ' <br /> CNROJEM0000011.000 5011-03.doc 12 <br /> i <br />
