Environmental monitoring at mine sites — Future directions

"The level of scientific knowledge about the effects of contaminants is increasing and changes in environmental monitoring are likely to allow for the assessment of environment effects particularly to the aquatic environment. This paper provides an overview of recent developments in this area which include the environmental effects monitoring program for pulp and paper operations, the assessment of the Aquatic Effects of Mining (AQUAMIN) program, the Aquatic Effects Technology Evaluation (AETE) program, and the review of the federal Metal Mining Liquid Effluent Regulations (MMLER). The paper also provides a look forward at the direction of environmental monitoring of mine projects in Canada. IntroductionEnvironmental monitoring programs provide a wide range of data to environmental management systems, regulatory authorities, and stakeholders. The data obtained are used to demonstrate that operations are in compliance with regulatory environmental protection requirements, and provide the scientific basis for assessing the effectiveness of environmental protection measures. Environmental monitoring requirements for mine projects are established based on the type of operation, site specific issues and concerns, and the requirements of regulators and mine proponents.The level of scientific knowledge regarding the potential effects of contaminants on the receiving environment is increasing, and in particular with regards to the receiving aquatic environment. Regulatory controls regarding the protection of fish, fish habitat, and fishery resources are being reviewed with regards to their adequacy, and the environmental effects monitoring program on the pulp and paper industry is expected to provide useful data relevant to those types of operations. These developments are of interest to mine proponents as it is presently expected that an environment effects monitoring program will be developed specifically for the metal mining industry under a regulated environmental effects monitoring program as part of the Fisheries Act. This paper reviews recent developments in this area, and provides a look forward on the future directions of environmental monitoring programs."
