Lakes Environmental Presents CALPUFF Modelling Poster at Air Quality Workshop in Banff, Alberta! |
Lakes Environmental participated in the Fourth Canadian Workshop on Air Quality in Banff, Alberta,
from Feb. 14-16. Dr. Kahing Yau presented his poster titled “A Regional Air Quality Assessment
with CALPUFF Modelling on a Grid Computing Platform,” co-authored with Dr. Jesse Thé. To view the poster, please visit
https://www.weblakes.com/calpuff/RegionalAirQuality_CALPUFF.pdf
The theme for the AQ2006 workshop was Air Quality: Piecing the Puzzle. The workshop brought
together experts in modeling, monitoring, research, and policy in order to share knowledge and
bridge gaps in understanding air quality issues.
Dr. Yau is our senior meteorologist responsible for advanced R&D in atmospheric science modeling.
Dr. Jesse Thé is the president and founder of Lakes Environmental Inc.

Lakes Environmental Presentation at A&WMA Climate Change Conference in San Francisco, California |
Lakes Environmental participated in the “Planning for the Future: Climate Change, Greenhouse Gas Inventories
& Clean Energy Linkages” conference, which was held in San Francisco from March 7 to March 9, 2006. The conference
was organized by the Air and Waste Management Association and sponsored by the San Francisco Bay Area Air Quality
Management District and others.
The Conference acknowledged that climate change is a serious threat to humankind due to its bulk scale that stretches
beyond any nation’s boundaries as well as its adverse impacts on humankind’s social, economic, and environmental
values. Dr. Luai Hamouda presented a policy paper that investigates the future of the climate change regime using
the graph model for conflict resolution. You may read a copy of the paper, “The Future of the Climate Change
Regime: A Strategic Analysis” at
https://www.weblakes.com/project_experience/Future_ClimateChange Regime.pdf.
Dr. Luai Hamouda, P.Eng, is Lakes Environmental's Business Development
Manager.

Monthly Modeling Tip

Modeling Tip: Emission Rates for Area Sources in Risk Assessment Projects |
When conducting a risk assessment project (e.g. one following the 2005 US EPA OSW HHRAP),
COPC emission rates for area sources should be specified in grams per second (g/s). This may cause
some confusion as the unitized emission rate specified for area sources in your ISCST3/AERMOD air
dispersion modeling project would have been specified as an emission rate in grams per second per
square meter [g/(s*m2)].
There are two methods that you can follow when specifying emission rates for area sources in your
air dispersion modeling input files and in your risk assessment project. These two methods are
explained in more detail below.
Method 1:
In your ISCST3 or AERMOD air modeling input file, set the emission rate for your area source to 1 g/(s*m2).
For example:
- The area source you are modeling has an area of 500 m2.
- Specify the emission rate for this area source in the ISCST3/AERMOD input file as 1 g/(s*m2).
- The total emission rate in g/s for the area source would be equal to 500 g/s [500 m2 * 1 g/(s*m2)].
If you used Method 1 for the air modeling unitized emission rate, then in your risk assessment project,
enter the area source COPC emission rate as if it was being specified in g/(s*m2).
For example:
- If the total emission of COPC A for the 500 m2 area source is 3.5 g/s, this equates to 0.007 g/(s*m2).
- Enter an emission rate of 0.007 g/s for COPC A for the area source.
Method 2:
In your ISCST3 or AERMOD air modeling input file, set an emission rate in g/(s*m2) such that the total
emission rate of the source is 1 g/s.
For example:
- The Area source you are modeling has an area of 500 m2.
- Specify the emission rate for this area source in the ISCST3/AERMOD input file as 0.002 g/(s*m2).
- The total emission rate in g/s for the area source would be equal to 1 g/s [500 m2 * 0.002 g/(s*m2)].
If you used Method 2 for the air modeling unitized emission rate, then in your risk assessment project
you must specify the emission rate for the COPC in g/s [Emission (g/(s*m2)) x Area of Source (m2)].
For example:
- If the total emission of COPC A for the 500 m2 area source is 3.5 g/s (or 0.007 g/(s*m2)).
- Enter an emission rate of 3.5 g/s for COPC A for the area source.

EPA’s science advisers disappointed by proposed PM standards
Under a set of standards [1.5MB PDF] published in January, the U.S. EPA is proposing to reduce
allowable levels of particulate matter (PM) found in the air people breathe, but not by as much as
its Clean Air Scientific Advisory Committee (CASAC) recommended. In an unusual move, CASAC members
criticized the proposed rule, saying it would not be sufficiently protective. The committee plans
to send a letter to EPA Administrator Steve Johnson explaining the scientific rationale underlying
its recommendations and calling for a tighter rule.

Linking China’s Air Pollution to Export Markets
As one of the world’s fastest growing industrial areas, the Pearl River Delta (PRD) region on China’s
south coast churns out more than $100 billion worth of goods annually. Factory after factory produces
inexpensive items, such as electronics, clothing, and toys, most of them destined for export to eager
consumers in North America, Europe, and other parts of Asia. The dark side of this economic powerhouse
is high levels of air pollution.
