10 5.0 TEST MEDIA 5.1 Description of Test Media As described in Section and 4.2.3, the testing media for all hydrostatic tests defined in this plan will be water. Because there is no risk of the test media freezing during the proposed testing window, no additives will be utilized. No other alternative test media will be permitted for use in the tests defined in this plan. 5.2 Diversion of Test Media Process Piping The primary source of water for the hydrostatic testing of process piping will be the City of Regina commercial fill station, located beside the Co op Food Store at 1805 Winnipeg Street, immediately northwest of Enbridge Regina Terminal. This fill station is supplied by the City of Regina water main system, and is available for the public and local businesses to purchase potable water. Supply Location 80 Hydrotest Location Engineering and Projects Rev 1 Jun. 12, 15 Page 10 of 18

11 Water will be trucked from the City of Regina fill station to site via standard water trucks, owned and operated by Badger Daylighting Inc., under the direction of Graham Industrial Services LP and Enbridge. As the water supplied from this location is potable water, no quality testing will be required prior to use. Moreover, due to the limited amount of water required, and the proximity of the fill station to Enbridge Regina Terminal, no special transportation or traffic control measures are required for the transport of water to site. Furthermore, no water diversion permits are required. In the event that the required water is not available from the City of Regina fill station, the secondary source of water will be the retention pond at the Consumer s Co operative (Co op) Refinery, located at th Avenue N, immediately north of Enbridge Regina Terminal. Enbridge has a long standing and mutually cooperative relationship with the Co op Refinery, and has recently utilized water from this retention pond to hydrostatically test the newly constructed Tank Fire Suppression Piping The primary source of water for the hydrostatic testing of the new fire suppression piping servicing Tank 80 will be the existing Enbridge firewater system at Regina Terminal. The existing Enbridge firewater system is supplied by the City of Regina. Water will be transported from the supply location to the test location via a standard water truck, owned and operated by Graham Industrial Services LP. Transport will be via private, Enbridge owned roads only. Due to the very small volume of water required for this hydrostatic test, no specific water diversion permit is required. 80 Hydrotest Location Supply Location Engineering and Projects Rev 1 Jun. 12, 15 Page 11 of 18

12 5.3 Disposal of Test Media Process Piping Following completion of hydrostatic testing of the process piping, the test water will be disposed of at PV Waste Solutions facility, located at 4101 Rochdale Blvd., Regina. This facility is specifically designed to dispose of wastewater from industrial processes and worksites. Prior to transporting wastewater to this facility, Graham (or a designate) will test the water per the requirements of PV Waste Solutions. Wastewater will be transported to the disposal facility via standard water trucks, owned and operated by Badger Daylighting Inc., under the direction of Graham and Enbridge. Due to the small quantity of water required for testing, no special transportation or traffic control measures are required for the disposal of this test media. Disposal Location Hydrotest Location Engineering and Projects Rev 1 Jun. 12, 15 Page 12 of 18

13 5.3.2 Fire Suppression Piping Following completion of hydrostatic testing of the fire suppression piping system described in Section 4.2.1, the test water will be removed from the piping system via standard water trucks, owned and operated by Graham. Due to the small quantity of water required for this test, the test water will be retained in the water trucks onsite, and used to water the private roadways inside Enbridge Regina Terminal as needed. Prior to any use, this hydrotest water will be tested for ph and total metals. The results of these quality tests must meet the environmental requirements of the Province of Saskatchewan and the City of Regina to proceed with the disposal procedure described above. If the results of quality tests are found to be outside these environmental requirements, the water will be trucked offsite to PV Waste Solutions, as detailed in Section above.
