Permitted Emissions Permitted emissions from Terrace area point sources are depicted in the tables below. The first table depicts the permitted amount of atmospheric contaminant emissions expressed in tonnes per year. The second table expresses these emissions as frequencies relative to the total emitted for each individual atmospheric contaminant. The annual emissions are extracted from the BC Environment Permit Fees Database. The permit fees database provides a consistent reference between sources for permitted emissions data.
Environmental sensitivity can refer to human health, vegetation damage, damage to materials, etc.
Air Quality Monitoring History Assessments of atmospheric particulate matter emissions have been ongoing in Terrace for quite some time. Early monitoring programmes in Terrace focused on nuisance emissions from local industry. These consisted of a network of dustfall monitoring canisters to quantify the fallout of coarse particulate matter from the atmosphere. This network is still in place and is maintained by Skeena Cellulose and Skeena Sawmills. In recent years health impacts of inhalable particulate matter have emerged as a significant area of environmental concern.
