Air Pollution Advisory for September 6-9, 2019

The Glenn County Air Pollution Control District and the Glenn County Public Health Department are issuing this Air Pollution Advisory to notify the public of potential poor air quality conditions in Glenn County due to smoke from multiple fires in surrounding counties. Regional air quality is forecast to potentially reach unhealthy levels.  Smoke impacts are expected to vary during the course of the next several days depending on wind direction and the intensity of the fire activity.

The major air pollutant of concern is fine particulate matter also known as PM2.5. While all persons may experience varying degrees of symptoms, more sensitive populations, such as the young, the elderly, pregnant women, smokers, and those with respiratory conditions, are of greatest risk to experience more aggravated symptoms which may include but are not limited to coughing, watery and itchy eyes, and difficulty in breathing. Some N95 masks may be available at the Public Health office in Willows for the most vulnerable populations.


Persons experiencing questionable or severe symptoms should seek professional medical advice and treatment.  The following actions are recommended as needed in areas impacted by smoke during the poor air pollution periods:


  1. Limit outdoor exertion by children, students and adults;
  2. Reduction in travel including unnecessary driving;
  3. Avoid the use of non-HEPA paper face mask filters which are not capable of filtering extra fine particulates;
  4. Check or replace air conditioner filters.
