CASAs Ambient Monitoring Strategic Plan
My intent with this blog is to provide an update for the TWS and to start a conversation regarding our needs and desires for AAQ Monitoring in Alberta. I will detail the purpose, vision, and goals, then discuss in less detail how these high level concepts will be rolled out and implemented.
Workshop Purpose
To present the proposed Ambient Monitoring Strategic Plan and receive feedback from CASA stakeholders
The Management Plan
To support pollution prevention, continuous improvement and keeping clean areas clean, the following vision, principles and goals have been developed.
Vision
The vision of Alberta’s ambient air monitoring system is that it provides the data required to
a) assess air quality on a short- and long-term basis on a provincial scale; and
b) respond to specific local and regional air quality and air quality-related issues and concerns.
Principles
- The data gathered from Alberta’s ambient air quality and deposition monitoring network will be reliable and representative.
- Alberta’s ambient air and air-related deposition will be monitored using strategies and technologies that are consistent with best practices and end-use needs and will include the use of remote sensing and computer modeling to support and inform physical monitoring.
- The monitoring of Alberta’s ambient air will be responsive to changes in base conditions, such as population, emission sources, and profiles, and to changes in scientific or technical knowledge.
- Evolution of, and enhancements to, the ambient monitoring system will be constantly considered as opportunities arise, and will be guided by technological advancements.
- The air quality and deposition information generated will be used by many stakeholders, who need to be involved in ensuring the system is effective.
- The process of managing the overall system will include multi-stakeholder consultation and collaboration.
- Sampling programs will be designed so that uncertainties around results and representativeness can be assessed, which in turn makes it possible to undertake risk assessments using network data.
- Funding for the system will be on an emitter-pay basis.
Goals
Two goals will guide the ongoing development of Alberta’s ambient air and deposition monitoring system:
Goal 1 – Gather the right data
Collect reliable and representative temporal and spatial data on Alberta’s ambient air quality and related deposition in an efficient and economically sustainable way.
Goal 2 – Disseminate data and information
Use ambient air quality and deposition data to produce information that is relevant and credible. This data and information will be easily accessible to the people of Alberta in a timely manner.
Commentary
I think that we should be conducting AAQ monitoring with the goal of understanding the range of substances and concentrations of those substances in our ambient air. There are two outcomes associated with this understanding; the management of those substances for the protection of human health and ecosystem health. Within this framework, the monitoring of the air should be divided from its management. As such, I have the following concerns with part B of the Vision - "respond to specific local and regional air quality and air quality-related issues and concerns":
1. To respond to specific local and regional air quality issues is several steps away from the monitoring of the air. I think that a response strategy should be developed, but as a separate and distinct plan.
2. To respond to specific local and regional air quality issues is not strategic, it is reactionary.
3. What is the point of an airshed, if not to respond to local and regional issues.
Perhaps a Part B Vision would read something like "To ensure that the appropriate substances are monitored at the appropriate location with the best available technology."
The intent of this is to follow up on the assessment piece by indicating that the plan would call for monitoring the right thing, in the right place with the right technology.
Principle 5 is also of concern because the use of the data by stakeholders is beyond the control of a monitoring plan; and there should be a third goal addressing the need for continuous improvement in the collection of data and generation of information.
I like that there are a number of monitoring objectives outlined for the strategic plan:
Monitoring Objectives
What will we monitor?
1. Assess the impact of outdoor air quality on human health for both urban and rural populations.
2. Characterize background air quality in Alberta.
How will we monitor?
3. Assess the impact of air quality and deposition on ecosystem and animal health.
4. Characterize air quality entering or leaving the province (boundary transport).
5. Address gaps in air quality and deposition monitoring for Alberta.
6. Support the monitoring and reporting requirements associated with air quality or deposition management frameworks and other obligations.
7. Verify or calibrate air emission dispersion, transformation and deposition computer models and ground truth remote sensing data.
What will be done with the data?
8. Assess and report on poor air quality events.
9. Determine air quality relative to ambient air quality objectives, guidelines, standards or criteria.
10. Enable determination of the relative significance of anthropogenic and biogenic emission sources or types on air quality or deposition.
11. Support long-term trend analysis and state of the environment reporting to the public, as well as other forms of education and outreach on air quality management.
Commentary
My issue with the monitoring objectives is that they are not explicitly linked to the following sub-programs defined for the strategic plan:
1. Population-based Monitoring Sub-program
2. Ecosystem-based Monitoring Sub-program
3. PM2.5 and Ozone Monitoring Sub-program
4. Boundary Transport Monitoring Sub-program
5. Background Monitoring Sub-program
6. Provincial Spatial Scale Monitoring Sub-program
7. Industry Compliance Monitoring Sub-program
Each program’s intent is described, but I think that some effort should be put into defining objectives for each sub-program. The point of these objectives is to provide guidance for the unique needs of each sub-program in their implementation and assessment. The objectives should define when monitoring requirements change, and how to address these changes. Also, the objectives provide the starting point for performance measures.
Performance measures are completely absent from the monitoring program. Experience at CASA has shown us that performance measures are key to the successful implementation of any program in that they provide the metrics with which to gauge and measure success. Performance measures will address the need to gauge continuous improvement component of the monitoring plan.
Funding
Funding is the big elephant in the room. As the 1995 Ambient Monitoring Strategic Plan has taught us, the most well thought out ambitious plans will fall apart is sufficient funding is not found to implement the plan. The current thinking on funding lays out a number of high-level principles:
1. Costs will be apportioned to emitters relative to their emissions in proportion to the costs associated with the air quality and deposition monitoring.
2. Costs will be apportioned to emitters in a fair and equitable manner;
3. For emitters who are not currently paying their share of the monitoring costs, the provincial government will take responsibility for obtaining the share of funding apportioned to diffuse anthropogenic emissions. Until a mechanism is in place for obtaining the funding share from diffuse emitters, the provincial government will cover the costs directly;
4. The provincial government will develop a mechanism to identify small industrial emitters and ensure that those pay into the system in proportion to the emissions they generate. Until a mechanism is in place for obtaining the funding share from small but significant industrial emitters, the provincial government will cover the costs directly.
5. Data and information from this monitoring system will be publicly available. However, data users whose specific needs require additional system resources will pay the costs associated with meeting those needs;
6. Provisions will be included to ensure long-term funding;
7. Those who reduce their emissions should be recognized; and
8. There will be flexibility for airsheds to meet their own unique needs and acknowledge previously negotiated funding agreements.
Commentary
These principles are great, but it was unclear the level of buy-in from industry, and it was also unclear the role of AENV in securing the necessary funding based on these principles. I think that, if applied as stated, the above principles will form the basis for an equitable funding formula. But, due to the cost and contentious nature of funding this system, AENV should be committed to the gathering of these funds from industry and in developing a mechanism to levy funds from non-point sources in the absence of consensus.
Data Management Commentary
Question: Has the TWS developed a position on the Environment Canada Health Based AQI?
I think that the data management system is sound in that they gather data from a number of sources (point source emissions, non-point source emissions as well as the obvious ambient air quality) and have these data available on a website for download. It was unclear to me how these data will be used to generate information, and who will do this work. My feeling is that information cannot be generated by consensus. It should be up to the GOA and Health Regions to interpret this data and provide summary reports on air quality and potential human and ecosystem health impacts.
Thats it. Please comment.
