Description

The Air Monitoring Directive (2016) supersedes the original 1989 Air Monitoring Directive and the 2006 Amendments to the Air Monitoring Directive, 1989. Alberta’s Air Monitoring Directive (AMD) sets out the requirements for monitoring and reporting air quality in the province. The AMD is made up of nine chapters, which will be reviewed and revised as needed. Amendments or new draft chapters will be posted for public review. Note that Chapter 2 of the AMD was repealed as of December 2019. See the related tab of this record to view superseded and repealed versions of directive chapters.

Description

This report is the final deliverable of an air quality modelling contract. The study built upon previous modelling studies focused on central Alberta and expanded the scope to include all regions of Alberta. Other improvements in this study included modelling a complete calendar year, emissions inventory updates for key sectors, and sector-based source apportionment for seven distinct sectors. Province-wide source apportionment will help inform air quality management initiatives, such as managing against the Canadian Ambient Air Quality Standards and other provincial air quality frameworks.

Description

This study investigates key issues identified in the Joint Canada-Alberta Oil Sands Monitoring program regarding water quality of tributaries to the lower Athabasca River, specifically: the current state of water quality; the distribution of contaminants; whether the presence of toxic substances is increasing or decreasing, and their rate of change' and whether substances added to the rivers by natural and man-made discharges are likely to cause deterioration of water quality.

Non-point source pollution originates from many different and diffuse sources, which collectively can have a significant impact on air quality. The Non-Point Source Project of the Clean Air... More ≫

Description

Non-point source pollution originates from many different and diffuse sources, which collectively can have a significant impact on air quality. The Non-Point Source Project of the Clean Air Strategic Alliance began in November 2015 with the goal of recommending management actions to reduce air emissions from non-point sources in Alberta, focusing on areas that were approaching or not achieving the Canadian Ambient Air Quality Standards. This report presents the findings of the project and makes recommendations related to mobile sources (transportation), construction operations and road dust, open-air burning, commercial and residential heating, industrial non-point sources, land-use planning, addressing non-point source knowledge gaps and uncertainties, and considering air quality co-benefits with climate change initiatives.

Description

Analysis for continuous hydrocarbon monitoring and meteorological data at the two stations in the Three Creeks area showed that elevated hydrocarbon concentrations were associated with low wind speed, likely promoted by nocturnal gravitational drainage flow. In addition with higher concentrations of THC may be promoted by lower mixing height, elevated NMHC concentrations were more likely to be measured during the warmer months, when evaporation losses are more likely.

Description

The objectives of the 2014 investigation and monitoring program were to: Evaluate the potential for vapour migration in residences in the area; Assess exposure and risk to residents in the vicinity through direct measurement of indoor air; Investigate the effects of seasonality on potential vapour intrusion, soil vapour concentrations and presents of NAPL; Evaluate if attenuation and if possible biodegradation is occurring between the source and residents; and where possible, delineate the extent of NAPL in the vicinity of monitoring well MW10-6 and further characterize soil and groundwater conditions in this area.

Description

The findings from the science investigation demonstrate that the fine particulate matter issue in the Capital Region is complex. Many factors can contribute to elevated particulate matter concentrations and the challenges in modelling fine particulate matter for source apportionment purposes contribute to this complexity.
