Air Emissions

The TREE team has determined that most facilities can save money and reduce their environmental liabilities by becoming familiar with air quality laws and regulations specific to their facility. The team can help identify specific areas in your facility that may reduce your air emissions and improve compliance with applicable air quality rules.

Common Issues

These are issues that the TREE Team has seen at multiple companies. The team can help you identify and correct these issues along with others, specific to your site.
  • Wood burning devices. Washington State has strict laws about wood stoves and other wood burning devices, such as wood furnaces, manufactured fireplaces and outdoor wood boilers. Not every wood stove that is sold in other states can be sold in Washington State. To avoid possible civil penalties, you need to
         1) check that your wood burning device is certified in Washington;
         2) obtain necessary permits; and
         3) follow local building codes.
  • Boilers. Use new low-NOx burners to fire your boilers. Low-NOx burners will reduce air emissions, are more efficient, and will ultimately save you money. If your boiler is over 10 years old, there is a good chance you are spending more money to run your boiler than you need to.
  • Fuel Use. Use of renewable fuels, liquefied petroleum gas and natural gas will generally reduce your air emissions, and improve your compliance with air quality rules. If using diesel fuel, switching to ultralow sulfur diesel fuel will reduce your air emissions, and may reduce regulatory costs.
  • Air pollution control. Regular inspection and maintenance of air pollution control devices such as scrubbers, electrostatic precipitators, baghouses, or cyclones could save you money and improve your compliance with air quality rules. Poorly maintained control devices could lead to excessive energy consumption. Excessive visible emissions are generally a symptom of poorly maintained control devices.
  • Fugitive emissions. Check that you are not wasting valuable materials and energy through controllable fugitive emission points and areas.
