Alberta Environment adopted the Acid Deposition Management Framework developed by the Clean Air Strategic Alliance for management of acid deposition effects in Alberta. The framework was described in the report: Application of Critical, Target, and Monitoring Loads for Evaluation and Management of Acid Deposition (AENV, 1999). The framework prescribes a 5-year assessment cycle.

The Acid Deposition Assessment Group (ADAG) was appointed by Alberta Environment to guide the assessment and review the framework. ADAG consists of representatives from government, industry, and environmental organizations. Three documents were produced:
• an acid deposition assessment report
• a framework review report, and
• an acid deposition management framework document
This document describes the Alberta Acid Deposition Management Framework that is based on the application of critical, target, and monitoring loads and replaces the previous report in 1999.

Explains how Alberta's air quality is affected by natural factors, like climate and weather, and human factors, such as economic activity and industrial emissions. Long-term air quality data for several important contaminants and Alberta's approach to managing air quality are detailed in the report.

The document reports a study that further investigated the inferential methods that can be used by government and industry in Alberta for improved acid deposition management.

Acid deposition occurs when acid-forming pollutants in the air are
deposited on the earth’s surface. The main acid-forming pollutants are
sulphur dioxide (SO2) and oxides of nitrogen (NOx).

The document reports a study that examined the performance of the Alberta Environment’s inference model relative to the Environment Canada’s model for predicting dry deposition in Alberta and used this performance comparison to recommend changes for a number of assumptions and boundary conditions in the AENV inference model to improve its performance.

The document reports a study that examined current approaches used for measuring and estimating dry deposition and identified whether a relatively economical technical approach can be put into practice for measuring and estimating dry deposition of acidic substances in Alberta.

The Acid Deposition Assessment Group (ADAG) was appointed by Alberta Environment (AENV) in 2002 to function as an advisory body to the implementation and review of the Acid Deposition Management Framework: Application of Critical, Target, and Monitoring Loads for the Evaluation and Management of Acid Deposition (AENV, 1999). This framework, referenced as ‘the 1999 framework’ in this document, prescribes a 5-year assessment cycle.

Study completed as recommended by CASA’s Draft Ambient Monitoring Strategic Plan to assess the current acid deposition monitoring network in Alberta. It provides a ranking of current stations in terms of their importance to the overall sampling errors of the network. It also identifies potential new sites and ranks them in terms of their contributions to the reduction of overall sampling errors. The results are useful for locating stations and general improvement of the network.
