REVISED PROJECT DESCRIPTION AND ENVIRONMENTAL IMPACT ASSESSMENT (<strong>EIA</strong>) REGISTRATION FOR THE<br />
NEPISIGUIT FALLS GENERATING STATION MODIFICATION AND REHABILITATION PROJECT<br />
Appendix A: New Brunswick <strong>EIA</strong> – Additional In<strong>for</strong>mation Requirements<br />
Final Report<br />
v) Siting Considerations The Project will be constructed within <strong>the</strong> footprint of <strong>the</strong> existing<br />
<strong>for</strong>ebay, dam and hydroelectric generating station at Nepisiguit<br />
Falls. The property has been used <strong>for</strong> <strong>the</strong> purpose of generating<br />
electricity since 1921. No alternative sites were considered as<br />
<strong>the</strong>y would not meet <strong>the</strong> Project purpose.<br />
The Project is located within 30 metres of a watercourse by nature<br />
of <strong>the</strong> Project (i.e., a dam and hydroelectric generating station).<br />
No wetlands, including riparian wetlands, were identified within <strong>the</strong><br />
Project development area, nor would any wetlands be affected by<br />
Project activities.<br />
The Project is not located within a designated wellfield or<br />
watershed. No Project activities are anticipated to influence<br />
potable wells during any phase of <strong>the</strong> Project.<br />
The Project is not located within Coastal Zone A or B (not<br />
applicable as <strong>the</strong> Project is not located near <strong>the</strong> coast of <strong>the</strong><br />
marine environment).<br />
