REVISED PROJECT DESCRIPTION AND ENVIRONMENTAL IMPACT ASSESSMENT (EIA) REGISTRATION FOR THE NEPISIGUIT FALLS GENERATING STATION MODIFICATION AND REHABILITATION PROJECT 3.10 ROAD TRANSPORTATION The road transportation network around the NFGS includes the following. • Route 430 is a local highway and resource road though a mostly undeveloped area of northeastern New Brunswick. Route 430 is approximately 111 km in length and connects Bathurst in the north to Miramichi south through Heath Steele Mines where it becomes unpaved, approximately 40 km southwest of the LAA. • Nepisiguit Falls Road is a local road approximately 5 km long, and connects Route 430 in the north to the NFGS through the rural residential community of Bathurst Mine. • Route 360 is a connector highway through an undeveloped area. Route 360 is approximately 20 km long and connects to Route 430 to the north and Routes 8 and 160 at Allardville to the west of the NFGS. Page 32 June 15, 2011
REVISED PROJECT DESCRIPTION AND ENVIRONMENTAL IMPACT ASSESSMENT (EIA) REGISTRATION FOR THE NEPISIGUIT FALLS GENERATING STATION MODIFICATION AND REHABILITATION PROJECT 4.0 ENVIRONMENTAL EFFECTS ASSESSMENT 4.1 METHODOLOGY To determine the potential for interactions between the Project and the environment, a qualitative rating system is employed. The interactions between the Project and each Valued Environmental Component (VEC) are ranked based on the following rating system, according to the professional judgment and experience of the study team. 0 = No interaction. The environmental effects are not significant and are not considered further in this report. 1 = Interaction occurs, however, based on past experience and professional judgment the interaction would not result in a significant environmental effect, even without mitigation; or interaction would not be significant due to application of codified environmental protection practices that are known to effectively mitigate the predicted environmental effects. The environmental effects are not significant and are not considered further in this report. 2 = Interaction could result in an environmental effect of concern even with mitigation; the potential environmental effects are considered further in this report. Where a potential Project-VEC interaction (i.e., a ranking of 2) is identified through the qualitative rating system, further discussion of the potential interaction is provided in the subsequent section. However, where no interaction or no substantive interaction is identified (i.e., a ranking of 0 or 1), the rationale of why no interaction exists, or why a limited interaction can be adequately mitigated without resulting in significant environmental effects, is provided, but the environmental effects are considered not significant and are not discussed further in this report. The evaluation is provided in tabular form for ease in evaluation and communication. 4.2 POTENTIAL INTERACTIONS OF THE PROJECT WITH THE ENVIRONMENT 4.2.1 Project-Environment Interaction Matrix Based on the Project Description and the methodology described briefly above, the potential interactions between the Project and the environment are summarized in Table 4.1.
