Weather Influences Air Quality

Friday, August 01, 2014 - Weather influences our day-to-day air quality even though emission of pollutants is the source of air quality degradation, the weather largely determines the quality of the air we breathe day-to-day. As air pollution rises vertically and is transported horizontally, the less concentrated it becomes. Here are ways our weather influences our day-to-day air quality.

High Pressure

When a high pressure air mass moves into our region, it is accompanied by "fair" weather: light winds, lack of storms and precipitation with few clouds. High atmospheric pressure can be of particular concern for air quality because the weather conditions it brings usually inhibit motion in the atmosphere, both vertically and horizontally. These weather elements can allow air pollution to build to unhealthy levels.


EPA's 2012 Toxics Release Inventory Shows Air Pollutants Continue to Decline

Tuesday, July 01, 2014 - The total release of toxic chemicals decreased 12 percent from 2011 to 2012, according to the U.S. Environmental Protection Agency's (EPA) annual Toxics Release Inventory (TRI) report. The decrease includes an eight percent decline in total toxic air releases, primarily due to reductions in hazardous air pollutant (HAP) emissions.

The annual TRI report provides citizens with critical information about their communities. The TRI Program collects data on certain toxic chemical releases to the air, water, and land, as well as information on waste management and pollution prevention activities by facilities across the country. The data are submitted annually to EPA, states, and tribes by facilities in industry sectors such as manufacturing, metal mining, electric utilities, and commercial hazardous waste. Many of the releases from facilities that are subject to TRI reporting are regulated under other EPA program requirements designed to limit harm to human health and the environment.

This year's TRI national analysis report includes new analyses and interactive maps for each U.S. metropolitan and micropolitan area, new information about industry efforts to reduce pollution through green chemistry and other pollution prevention practices, and a new feature about chemical use in consumer products.

More information on the 2012 TRI analysis, including metropolitan and micropolitan areas is available at EPA 2012 TRI National Analysis

5 Recreational Fire Reminders

Tuesday, July 01, 2014 - Summer is the perfect time for enjoying a Recreational Fire. These reminders will help make your summer fun and safe.

  • Recreational fires must be used solely for recreational purposes and may not be used for disposal of yard debris or any other material. A responsible party must be attending the fire at all times.

  • A Recreational fire is under 3x3x2 and is allowed without a permit. Recreational fires in excess of 3x3x2 need a special written permit from SWCAA.

  • Only charcoal or seasoned firewood (not lumber) may be used as fuel for a Recreational fire. A very small amount of paper may be used to start the fire.

  • Recreational fires may not cause a smoke or odor nuisance to surrounding properties.

  • Recreational fires must be fully extinguished and cool to the touch before leaving them unattended.
If you need further information please contact SWCAA at (360) 574-3058 x 110.
