What is the Health Advisory Program?The Great Basin Unified Air Pollution Control District will issue air pollution health advisories when air pollution exceeds selected trigger levels. District staff will take hourly readings of the wind speed, wind direction and particulate pollution levels in Mammoth, Bishop, Lone Pine, Olancha and Keeler, during normal business hours.
Health advisory notices will be text messaged and emailed to schools and interested citizens in the affected communities and to local media outlets. Health advisories will remain in effect for the remainder of the day and if appropriate, will be reissued as conditions change.
A Stage 2 air pollution health advisory will be issued when hourly particulate pollution levels exceed 800 µg/m³ for dust and 200 µg/m³ for wildfire smoke. A Stage 2 health advisory will recommend that everyone refrain from strenuous outdoor activities in the impacted area.
The GBUAPCD air pollution health advisory program is not intended to replace the need to control dust and smoke problems in the Eastern Sierra, but it's intended to help reduce adverse health effects until dust control measures are in place. If you have any questions about this program or the District's activities at Owens Lake, please contact us.
