Slide 7: Why Vegetation Maintenance is Needed
Why Vegetation Maintenance is Needed • To maintain reliability • To protect against outages • Imminent risk with some vegetation • Incompatible newly-planted vegetation • Worker and public safety concern • Comply with industry and regulatory standards Partners in Powerful Communities
Slide 8: Legislation
Legislation Electricity Act, 1998 • Grants Hydro One the primacy of the use over the transmission corridors for the purposes of operating the system and maintenance. • This includes vegetation maintenance. Easement Agreements • Transmission corridors are comprised of either provincially owned, munic

Slide 15: Proposed Future Maintenance Approach
Proposed Future Maintenance Approach Short-term and Long-term Partners in Powerful Communities
Slide 16: Future Maintenance Marchwood TS x Queensway
Future Maintenance Marchwood TS x Queensway The plan is developed with input from KBCA • More frequent vegetation maintenance in the short- run • Wire zone and border zone maintenance approach • Lead time for transplanting • Maintainable vegetation agreements • Provide a list of compatible species •
Slide 17: More Frequent Maintenance
More Frequent Maintenance • Transition the transmission corridor to a sustainable state through a phased approach • Three-year vegetation maintenance cycles in 2018 and 2021 to allow residents to replant with compatible vegetation on private properties. • Starting in 2024, return to standard six-yea
Slide 18: Transferable Vegetation Lead Time to Transplant
Transferable Vegetation • Hydro One will meet with individual property owners to identify transferable vegetation from the transmission corridor Lead Time to Transplant • Hydro One will identify incompatible vegetation on the transmission corridor and allow residents an opportunity to transplant • R
Slide 19: Maintainable Vegetation
Maintainable Vegetation • Site specific. • Maintainable vegetation may vary from property to property • Factors considered will be type of vegetation species, its current height, line sag and sway • Maintainable species must be approved by Hydro One • Homeowner is responsible for the maintenance Par

Slide 21: Compatible Species List For This Project Only
Compatible Species List For This Project Only • Site specific • Only suitable for transmission corridor between Marchwood TS to the Queensway • Available on the project website Partners in Powerful Communities
Slide 22: Types of Vegetation on transmission corridors
Types of Vegetation on transmission corridors 1. Compatible Species - Will not affect equipment or impede access 2. Incompatible Species - Will require maintenance at some point Partners in Powerful Communities
