Northern Gateway Pipelines Inc. Section 3.10: Site Plans and Technical Data Table of Contents 4.17.6 Recovered Oil Drain Tank The recovered oil drain tank will have a level transmitter that will alarm when the normal fill level of the tank is exceeded. If the tank level continues to rise, a level switch will be activated. Activation of the level switch will cause all pumps that discharge into the tank to shutdown and all motor operated valves associated with filling the tank to close. Secondary containment for the recovered oil drain tank will be provided by direct impoundment around the tank with a berm capable of containing 110 percent of the volume of the tank and any local rainwater within the containment area. Tank Floating Roofs Product tanks will be equipped with floating roofs, which have decreased hydrocarbon vapour space above the liquid level as compared to fixed roof tanks. Consequently, floating roof tanks assist in the reduction of volatile organic compound (VOC) emissions into the atmosphere. Other pollution prevention measures include a surge relief system that drains into the recovered oil tank to prevent against significant back pressures and potential loss of product containment. 4.17.7 Corrosion Protection The control of corrosion will be an important element of all steel structures. Steel structures that are not directly exposed to seawater will be protected from corrosion by paint. Steel structures exposed to seawater will receive additional corrosion protection from epoxy coatings and cathodic protection. External bottoms of field-erected tanks will be uncoated, but will be protected against soil-side corrosion by applying current from mixed metal oxide ribbon anodes installed within the tank base foundation. Internal cathodic protection of the tanks is not required as the tanks will contain pipeline grade hydrocarbon liquids. Tanks will have an internal protective coating applied to the floor and the lower 1.2 metres of the walls. The full height of the exterior walls, the floating roof vapour space, and the upper 0.6 metres of the internal walls will also be painted. 4.18 Operational Safety Procedures and Facilities 4.18.1 Terminal Operational Safety Procedures Northern Gateway’s operational policies, practices, and activities will give the highest priority to safety and stewardship of the natural environment. Preventative maintenance will be performed along with regularly scheduled safety and security inspections. The Operation and Maintenance Manuals will contain policies and procedures to address: • Terminal berthing; • Terminal loading and unloading; • Dock maintenance; • Tanker acceptance; • Product safety specifications; • Logging roads radio access control; and, • Fire protection.

Northern Gateway Pipelines Inc. Section 3.10: Site Plans and Technical Data Table of Contents Vessels will be required to follow procedures as recommended in the latest version of the International Safety Guide for Oil Tankers and Terminals (ISGOTT), and in accordance with Oil Companies International Marine Forum (OCIMF) and Tripod Catenary Moored Systems (TCMS) guidelines and regulations. 4.18.2 Port Information Booklet and Terminal Regulations Of vital safety importance to the visiting vessel, especially on its first occasion, is the receipt by the tanker and its owner of copies of the Port Information Booklet (see TERMPOL Study 3.16), and the Terminal Regulations (see TERMPOL Study 3.17). The Port Information Booklet will contain information about general marine subjects including pilots, tugs, weather, references to Canadian regulations, etc. The Terminal Regulations will include mandatory procedures and regulations for the tanker to follow while it is moored at Kitimat Terminal. 4.18.3 Cargo Transfer Safety Procedures A synopsis of the safety procedures conducted during the cargo transfer operations is presented below; refer to TERMPOL Study 3.11 for a detailed description of the general cargo transfer procedures. 4.18.3.1 Inert Gas Generation For all vessels arriving at Kitimat Terminal, it is critical that the vessel’s inert gas generation system is in good operating condition. The inert gas system limits the amount of oxygen in the cargo tanks of the vessel and prevents the formation of an explosive atmosphere. Prior to arriving at the terminal the vessel’s crew will monitor the cargo tanks and will operate the inert gas system as required to ensure the inert gas pressure and oxygen content comply with standard safe values. Verifying the vessel’s inert gas system is in good operational condition will form part of the vessel’s pre-transfer safety inspection. Unloaded vessels arriving at the terminal will be inspected to confirm that the empty tanks contain inert gas at the prescribed concentration. 4.18.3.2 Mooring Procedures All laden vessels, and under certain conditions ballasted vessels, will be escorted by escort tug(s). As a vessel approaches the terminal, harbour tugs will also be deployed to assist the vessel into the berth. To help in the berthing operation, the terminal will also be equipped with a docking aid system including an on-deck display to monitor the speed, distance and approach angle of the vessels as detailed in Section 4.12. Once a tanker has completed arrival manoeuvres and has been assisted onto the breasting structures by the tugs, it will be ready to secure its mooring lines by trained terminal personnel. The containment boom then is deployed in preparation for oil transfer operations. 4.18.3.3 Pre-transfer Safety Conference and Vessel Inspection The terminal will typically conduct a pre-transfer safety conference between terminal personnel and the ship’s representatives in charge of the cargo and ballast operations. After the safety conference, both terminal personnel and ship’s crew will conduct a vessel safety inspection. The inspection includes completing a safety and oil pollution checklist, in accordance with OCIMF and TCMS guidelines and regulations. The terminal personnel will also inspect the cargo tanks and establish communication links between the tanker and terminal. Any inspection failures will require rectification prior to the commencement of loading. January 20, 2010 FINAL - Rev. 0 Page 4-17
