The Brightwater Air Quality Advisory Board was formed to advise the county on any corrective actions necessary to achieve our commitment to no detectable odors at the property boundary of the Brightwater Treatment facilities or beyond.

The work and duties of the Board include:

  • Becoming familiar with the Brightwater odor control systems and operations
  • Having an understanding of the Brightwater odor monitoring and response plan
  • Reviewing background, baseline, and ongoing odor monitoring data
  • Reviewing odor complaints, investigations, and corrective action reports
  • Advising the county on any corrective actions necessary
  • The Board will meet quarterly to review the performance in meeting the stringent odor control standards for Brightwater. If necessary, the Board will provide recommendations for adjustments or improvements to the Brightwater odor monitoring and odor control system.
