Oil and gas developments can be associated with releases <str<strong>on</strong>g>of</str<strong>on</strong>g> a variety <str<strong>on</strong>g>of</str<strong>on</strong>g> chemicalsubstances into aquatic ecosystems. The substances that may be released in associati<strong>on</strong>with oil and gas developments include (Haggarty et al. 2003):• Metals (barium, cadmium, copper, lead, nickel, str<strong>on</strong>tium, vanadium, and zinc);• Petroleum hydrocarb<strong>on</strong>s (lube oils, diesel range organics, alkanes, extractablepetroleum hydrocarb<strong>on</strong>s)• M<strong>on</strong>oaromatic hydrocarb<strong>on</strong>s (i.e., benzene, toluene, ethylbenzene, and xylene);and,• Polycyclic aromatic hydrocarb<strong>on</strong>s (i.e., parent PAHs, alkylated PAHs, totalPAHs).As explorati<strong>on</strong> and development activities have been limited within the study area, it isanticipated that releases <str<strong>on</strong>g>of</str<strong>on</strong>g> c<strong>on</strong>taminants from oil and gas developments have been largelyassociated with spills associated with oil transmissi<strong>on</strong> facilities. No informati<strong>on</strong> waslocated <strong>on</strong> spills <str<strong>on</strong>g>of</str<strong>on</strong>g> oil or other materials from oil pipelines or related facilities in the <strong>Fraser</strong><strong>River</strong> Basin. Therefore, the extent to which oil and gas-related c<strong>on</strong>taminants have beenreleased to aquatic ecosystems within the study area is unknown.3.1.1.8 Bulk Storage and Shipping FacilitiesThere are a total <str<strong>on</strong>g>of</str<strong>on</strong>g> 24 bulk storage and/or shipping facilities located within the <strong>Fraser</strong><strong>River</strong> Basin, with the majority <str<strong>on</strong>g>of</str<strong>on</strong>g> these facilities located within the Lower <strong>Fraser</strong> <strong>River</strong>Area <str<strong>on</strong>g>of</str<strong>on</strong>g> Interest (Figure 3.8; Table 3.11). Many <str<strong>on</strong>g>of</str<strong>on</strong>g> these facilities are refrigerated storageand shipping operati<strong>on</strong>s (7) or warehousing and shipping operati<strong>on</strong>s (12). However,manufacturing, warehousing, storage, and shipping is c<strong>on</strong>ducted at <strong>on</strong>e <str<strong>on</strong>g>of</str<strong>on</strong>g> these facilities(i.e., Exel Global Logistics Canada Inc.). In additi<strong>on</strong>, import and export <str<strong>on</strong>g>of</str<strong>on</strong>g> freight, cargo,and/or c<strong>on</strong>tainers by ship is c<strong>on</strong>ducted at three <str<strong>on</strong>g>of</str<strong>on</strong>g> these facilities (i.e., <strong>Fraser</strong>-Surrey DocksLP, Hutchins<strong>on</strong> Cargo Terminal Inc., and Locher Evers Internati<strong>on</strong>al). One <str<strong>on</strong>g>of</str<strong>on</strong>g> thesefacilities is a fuel storage site that is operated by Terasen Pipelines (Trans Mountain) Inc.Finally, there are four in-river log storage areas located in the Lower <strong>Fraser</strong> <strong>River</strong> Area <str<strong>on</strong>g>of</str<strong>on</strong>g>Interest (see Nelitz et al. 2011 for more informati<strong>on</strong>).The c<strong>on</strong>taminants that could be released into the aquatic ecosystem from bulk storage andshipping facilities depend <strong>on</strong> the types <str<strong>on</strong>g>of</str<strong>on</strong>g> products that are stored <strong>on</strong> site, the mode <str<strong>on</strong>g>of</str<strong>on</strong>g>transport utilized, the number and quantity <str<strong>on</strong>g>of</str<strong>on</strong>g> spills that occur, and the proximity to theriver or other drainage pathways. No informati<strong>on</strong> was located to determine if any <str<strong>on</strong>g>of</str<strong>on</strong>g> the23
