Company Overview

Knight Pisold Ltd. of Vancouver, British Columbia, comprises a group of experienced and talented professional biologists and engineers who understand the complex needs of both industry and the environment, and provide environmental solutions in concert with sustainable resource development.

Knight Pisold Ltd. have managed and conducted numerous environmental impact assessments of mining developments throughout Canada, the United States and internationally. Their experience includes the coordination of Socioeconomic and Environmental Impact Statements for the B. C. Environmental Assessment Act (BCEAA), Canadian Environmental Assessment Act (CEAA), US Environmental Policy Act (NEPA), California Environmental Policy Act (CEPA) and the acquisition of all necessary permits, licenses and approvals.

Internationally they have experience with World Bank standards and environmental law in Turkey, Czech Republic, Peru, Argentina, Panama, Chile, Mexico and China. Knight Pisold Ltd. have developed considerable experience in the control of acid generation from waste rock and tailings disposal sites and have developed specialized knowledge in the treatment of gold mill effluents containing cyanide, barren bleed and complexed heavy metals.

For the power industry, Knight Pisold Ltd. completes hydrological and fisheries studies. Results from these studies are used to determine environmental impacts from and the necessary mitigation for the proposed hydroelectric project such as fishway installation, supplementary flow control and habitat replacement for government approval and permitting.

For numerous projects fisheries habitat assessments, riparian assessments, forest ecosystem network planning for wildlife, hydrogeomorphology, and restoration prescriptions are completed.

• Environmental Permitting And Detailed Environmental Baseline Studies

  Knight Pisold Ltd. is a progressive company dealing with complex and controversial environmental concerns both nationally and internationally. The company handles a diverse range of environmental issues using a broad range of disciplines from biology to hydrology, chemistry and engineering. All aspects of the ecosystem are addressed when determining the impacts of a development and when designing mitigative procedures which will fulfil government environmental requirements. Field work for baseline environmental studies and monitoring is conducted in all seasons according to a pre-determined sampling program designed to produce the most significant and accurate information possible.

  Knight Pisold's environmental study capabilities encompass a diverse field including, Environmental Permitting, Impact and Risk Assessment, Environmental Engineering, Reclamation and Abandonment Planning, Environmental Chemistry and Toxicology, Waste Characterization Studies, Waste Treatment Technology, Monitoring Mitigation and Environmental Audits.

  Knight Pisold Ltd. provides environmental impact assessments and permitting services to major projects both in North America and internationally. Specifically the company has been involved in the preparation of 'Environmental Impact Reports' for the Canadian, U. S. and European jurisdictions and providing assistance to companies in obtaining the essential permits, licenses and approvals. Knight Pisold Ltd. has also been involved in Environmental Audits, Liability Evaluations, Due Diligence Reviews, Environmental Effects Monitoring and Reclamation/Closure Planning.

• Extensive Water Quality Modelling And Literature Search To Determine, Defend And Recommend An Acceptable Discharge Scenario

  An open pit mine is in the process of closing and needs to release water in excess of existing permit levels. In order to defend a scenario of additional discharge, a number of water quality models were created that incorporated existing water quality, projected waste rock runoff quality and treated tailings supernatant quality. An extensive literature search on the toxicity of a number of metals and physical parameters on aquatic life was completed. This provided background for the defence and recommendations for amended permit levels with respect to the projected resulting water quality.

• Relocalisation De Neuf Paires D'ombles Tte Plate Pour Restaurer L'habitat De Poisson Dans Les Ruisseaux Voisins

  Aboutissement d'tudes de base multidisciplinaires et d'valuation d'impact pour l'attribution par le gouvernement d'un permis pour une mine dans le nord de la Colombie-Britannique, actuellement en phase de construction. Une fois la perte d'habitat de poisson mise en vidence, on a effectu des tudes extensives pour quantifier la perte d'habitat et la population de poissons utilisant le ruisseau. On a ensuite termin les tudes de remplacement de l'habitat de poisson afin de dterminer la faisabilit de la relocalisation de l'omble tte plate. Le transfert effectif se fait maintenant, avec un suivi rgulier pour dterminer le taux de russite.

• Use Mine Plans And Environmental Information To Develop Reclamation Plans And Costs

  Mine reclamation and closure planning should be incorporated early in the mine plan so that costs can be assessed and mine operations and waste storage can be conducted in a manner conductive to final reclamation. Early planning can often prevent or mitigate environmental problems before they start and can save money by gearing operations towards rather than counter to the closure plan. In the initial stages of mine development the potential mine plan schenarios will be reviewed along with the environmental baseline/environmental impact assessment. Based on this information reclamation options will be formulated. Costing will be done at this time to determine the most cost effective options which still provide for environmental protection.
