SE2 would become the largest new air polluter in the Fraser Valley air shed.
The vast majority of coal emissions in our province come up through the air shed from the U.S. mid-west.
The Georgia Basin/Puget Sound airshed is composed of two smaller airsheds, the Georgia Basin and the Puget Sound.
The remainder of the airshed has deposition which is less than the critical load.
Reduce the impacts of air pollution to human health, ecosystems and visibility in the GB-PS airshed;
This is a result of the large abundance of ammonia in the airshed due to intensive agricultural activity.
Networks to measure the atmospheric deposition are present within the Georgia Basin airshed in both Washington State and British Columbia.
Deposition measurements in U.S. portion of the air basin are conducted through the National Atmospheric Deposition Program/National Trends Network (NADP/NTN).
Climate Change Impacts of Water in Georgia Basin/Puget Sound
The Puget Sound portion encompasses the counties to the south of Whatcom County in Washington State.
Ground level ozone is a major environmental and health concern in the Georgia Basin/Puget Sound airshed.
Ground level ozone is a major environmental and health concern in the Georgia Basin/Puget Sound airshed.
Total sulphur and nitrogen loads have been declining since 1998 at both rural and urban locations in the airshed.
Fine particulate matter in monitored areas of the airshed is dominated by carbonaceous material (organic and elemental carbon).
Total sulphur deposition is less than 8 kg/ha/yr in most of the airshed.
Ground level ozone levels in most areas of the airshed are below national standards and regional objectives.
In addition, there are periods of time when air travels over parts of the continent before reaching the airshed.
Current levels of air pollution in the airshed have been found to have measurable health impacts.
The Canadian portion of the Georgia Basin-Puget Sound airshed is outlined in black and is colored according to critical loads of acidity for soils in eq/ha/yr.
This program is called the National Atmospheric Deposition Program/National Trends Network (NADP/NTN).
The current social and economic trends in the Georgia Basin/Puget Sound airshed have the potential to contribute to a decline in air quality.
Most of the air reaching the Georgia Basin/Puget Sound airshed has spent a number of days travelling over the Pacific Ocean.
In the Georgia Basin/Puget Sound airshed, air quality is monitored routinely by various air quality monitoring networks.
