What factors need to be considered in the establishment of emission standards:
-Technical feasibility and economical feasibility – Monitoring stations to measure actual emissions and ambient air quality – Enforcement by local authorities – Need to establish synergistic effects of the different pollutants involved on the environment and health – Dispersion modeling may be necessary for many urban areas – A fairly accurate estimate of future status (growth or decline) of the industry and population within the region
26
What are the atmospheric CO2 objectives for limiting global temperature rise?
450 ppm scenario: No more than 1.5 oC rise from the pre-industrial levels; * 500 ppm scenario: No more than 2.0 oC rise from the pre-industrial levels.
27
What are the characteristics of source-based regulations for emission standards and permits?
- Do not consider environmental quality - The regulatory limits that apply to each and every source depend on the nature of the source - Often devised from consideration of best available technology (BAT)
28
Why are air emission standards enacted?
To regulate the emission from industrial sources in order to ensure local ambient air quality
29
What influences the transport and dispersion of air pollutants emitted by point and area sources?
Meteorological conditions
30
Name the agreements that Canada has signed to reduce their greenhouse gas emissions.
1. Kyoto Accord 2. Copenhagen Accord 3. Paris Agreement 4. Kigali Amendment to the Montreal Protocol
31
What is the Pan-Canadian Framework on Clean Growth and Climate Change
In 2016, all Canadian jurisdictions were to implement carbon pricing mechanisms at least as stringent as a new national benchmark. * Provincial and territorial governments can choose to price carbon emissions through a tax or levy, or implement a cap and trade system. The Framework establishes a minimum carbon price of $10 per tonne of carbon dioxide equivalent (CO2e) in 2018, rising by $10 per year to reach $50 per tonne of CO2ein 2022.
32
What is the purpose of the BC carbon tax?
Government policy aimed at reducing GHG emissions in Canada
33
How does the nation-wide carbon pricing work for individuals and businesses?
For individuals and businesses with relatively small emissions, the carbon levy is applied to liquid and gaseous fuels at the point of purchase.
34
How does the financial scaling of BC's carbon tax work?
Beginning at $10/t CO2-eq emission (2018) and rising by $10/t each year to $50/t CO2-eq (2022); further increase by $15/t each year to reach $170/t CO2-eq by 2030.
35
Who does the output-based carbon pricing system apply to?
For big industrial emitters
36
What carbon pricing mechanisms do most Canadian provinces and territories adopt, and how do BC, QC, and NS differ in their approach?
-Most provinces and territories adopt the federal carbon levy and the output-based system. -British Columbia (BC) has a somewhat different carbon levy. -Quebec (QC) and Nova Scotia (NS) use a cap-and-trade system.
37
What are the objectives of British Columbia's carbon tax?
-Signal across the economy to reduce emissions. -Encourage sustainable economic activity. -Promote investment in low-carbon innovation.
38
What does BC's carbon tax apply to?
The purchase and use of fossil fuels. Approximately 70% of provincial greenhouse gas emissions.
39
What is the Canadian Environmental Protection Act (CEPA)?
Legislation that regulates management of hazardous waste recycling and disposal.
40
What is the division of responsibility for managing and reducing waste in Canada?
In Canada, the responsibility for managing and reducing waste is shared among federal, provincial, territorial and municipal governments.
41
How are environmental quality objectives set?
They are based on the impacts of specific pollutants on the environment and human beings.

What is the purpose of air quality objectives?
To protect the local environment and provide ambient air quality standards
45
What is the purpose of climate quality objectives.
To protect the global environment and prevent 450 ppm or 1.5 oC temperature rise.
46
What are the three components of air emission standards?
- Regional and sector emission standards (companies) – Local standards and local impacts – Local emission fees (companies)
47
What are the three components of GHG emission standards?
-Cap (Maximum allowed emissions) and trade (companies) – Local standards and global impacts (Ex. low carbon fuel standards) – Carbon tax (consumers)
48
What is the application of wastewater effluent regulations under the Fisheries Act?
Regulations would be applicable to all land-based wastewater systems that discharge effluent to surface water

62
What is the measurement for ceiling (indoor air quality standards)?
Instantaneously

What was Canada's committment to the Paris Agreement
Canada ratified the 2015 Paris Agreement, thereby agreeing to a reduction in GHG emissions of 30% from 2005 levels by 2030.
68

Canada is moving forward with regulatory measures to phase-out hydrofluorocarbons (HFCs).
69
What is the economic and technological impact of the BC carbon tax?
