Nalcor has a waste oil management system for handling and disposing of used oil. On an annual basis, facilities record the amounts of used oil generated and new oil purchased. Used oil is stored in either 205 litre drums or storage tanks and is collected by a certified waste oil handler for either recycling or reuse. Table 3 summarizes used oil information by location, used oil type, and volume collected. At Hydro’s central maintenance facility in Bishop’s Falls, insulating oil from transformers brought in for servicing is collected in oil storage tanks and processed for recycling if suitable. If the quality of the oil is not suitable for recycling, the oil is collected by a certified waste handler for proper disposal. In 2013, 23,600 litres of insulating oil taken from transformers was recycled with 10,724 litres disposed of as waste. This represents 69 per cent recycling of insulating oil at the central maintenance facility in 2013, down from 99 per cent in 2012. The amount of insulating oil disposed of as a waste will likely increase in the coming years due to the removal of oil-filled equipment with a PCB concentration between 2mg/kg and 50mg/kg; this oil cannot be reused and will have to be disposed of as a waste.

Spills and Other Incidents
The very nature of Hydro’s work to generate and transmit electricity requires the safe handling and use of a variety of potential environmental contaminants such as fuel oils, lubricating oils, and chemicals. Each year, Hydro uses about 300 million litres of fuel to generate electricity. The company strives to reduce the potential for leaks and spills.

CHURCHILL FALLS SPILL PREVENTION AND MANAGEMENT PROGRAM One of the ongoing programs in 2013 was the completion of an action plan to improve further the Churchill Falls powerhouse spill response and prevention measures. This plan maintained a target for spill prevention and response measures that the management at Churchill Falls has worked on for the past several years. This is a significant milestone because once all of the actions within this plan are completed, all identified prevention and response efforts will have been implemented. In 2013, stakeholders within the corporation and an independent consultant reviewed Nalcor’s River and Reservoir Spill Response Plan. The response plan was revised using the National Standard of Canada, “CAN/ CSA-Z731-03, Emergency Planning for Industry,” and reflects evolving needs within NE-CF. The plan uses local resources, but provides for the opportunity to call in external resources if required. NE-CF 2013 ENVIRONMENTAL PERFORMANCE REPORT

Excavation and removal of drill cuttings first began at the Seamus Site (Figure 4). This site is located 23 kilometers from the waste disposal site and would take longest to complete. Due to the time of year, excavated materials were nearly frozen during removal. This meant additional mitigation was not required inside the trucks to prevent liquids spilling from the vehicles on route to the landfill. A total of 160 loads were removed from the Seamus Site over six days. Work at the Finnigan Site (Figure 5) began on December 17 and was completed on December 22, 2013. Due to slurry conditions in two of the pits, some over-excavation was required to ensure complete removal of all drill cuttings. A total of 188 loads was hauled from this site, making the overall number of loads at 348. Figure 3: Project Rainbow Drill sites. 2013 ENVIRONMENTAL PERFORMANCE REPORT

The hydroelectric study is focused on possible hydro electric sites near Mary’s Harbour, Port Hope Simpson, Charlottetown, Makkovik, and Hopedale. The wind resource study is focused on wind power potential near Cartwright, Makkovik, Hopedale, and Nain. This initiative is guided primarily by the two main objectives outlined in the Newfoundland and Labrador Energy Plan: the protection of the environment through the reduction of emissions and the development of energy projects in the best long-term interests of residents of the province.
