This document comprises the Final Terrestrial Ecological Risk Assessment (ERA) Report for Teck's smelter operations in Trail, BC. It integrates all relevant data and analyses completed over the course of the ERA. It is not meant to be a stand-alone compilation of all data and previous reports. Rather, it summarizes the key data and identifies the sources from which these data were obtained. The specific sources of information used for the assessment of each objective are listed in the relevant section of this report.
The SALE analysis indicated that risk management objectives were being met for urban plants, agricultural crops, avian and mammalian wildlife, most Listed Species, and most livestock. Therefore, an evaluation of risk management options is not required for these receptors.
Risk management objectives may not be met for up to 7,900 ha of the AOI for wildland plant communities. However, the plant communities within the AOI have continued to develop since the time period used to develop the biophysical habitat map (aerial photograph taken in 1999) and the field data were collected for statistical analysis of plant community characteristics (2001). Therefore, consideration of risk management options should be based on an updated assessment of the status of plant community structure.
Risk management should be considered for the Lewis woodpecker (a Listed Species) related to availability of suitable nesting habitat. In addition, it is recommended that the restrictive covenant on title for lands currently holding such a covenant be maintained, as well as for any future Teck lands that are sold, due to the potential risks to young horses.
Prior to any risk management activity, a field survey for presence of individuals of Listed Species, as well as an evaluation of habitat suitability for Listed Species, should be conducted at an appropriate scale within the area subject to remediation.
