The specific monitoring requirements for each industrial operation are tailored to that facility based on the types and quantities of emissions. In general, the larger the emission source or the greater the potential for environmental impact, the more frequent and detailed the compulsory monitoring requirements will be.
While specific monitoring requirements vary, approvals stipulate that industrial operators must monitor stack emissions and the resulting ambient air around their facilities to demonstrate compliance with emission limits and ambient air quality objectives.
In-stack emissions monitoring occurs in two ways:
- Manual stack surveys - conducted by trained personnel who collect samples from the stack; or
- Continuous emissions monitoring - conducted with equipment installed on the stack.
Industry is required to submit regular monitoring reports to Alberta Environment and Parks. The reports summarize the source monitoring data and outline problems which may have arisen and corrective actions taken. Any measured exceedence of an approved limit must be reported immediately including the source, type and cause of the exceedence.
