Air Quality Information
Air Quality Reports
The Town of Mammoth Lakes in coordination with the Great Basin Unified Air Pollution Control District (GBUAPCD) continually monitors air quality in Mammoth Lakes. Data is obtained via a monitoring station operated by the GBUAPCD. During the winter season, generally November 15th through March 15th, the Town will announce "no wood burning" days when air quality is forecast to approach unhealthy levels. The GBUAPCD provides the Town with annual reports on air quality.
In addition to the annual reports, the GBUAPCD also provides triennial progress reports, as required by the 2014 Air Quality Management Plan (2014 AQMP). The report provides a progress report on PM-10 air quality trends for the Town and is sent to the EPA for verification that the Town remains in attainment for the PM-10 National Ambient Air Quality Standard (Federal Standard). The report is to be completed every 3 years beginning in 2017.
Burn Hot, Clean Fires to Keep our Air Clean
When Mammoth Lakes experiences periods of clear, cold, and calm weather, the air quality deteriorates.
To keep the air as clean as possible, please do your part by following these simple steps:
- Only burn clean and hot fires
- Check your chimney periodically for emissions (if smoke is clearly visible, your fire needs more air, the wood is not dry enough, or the wood is not split small enough)
- Call (760) 934-1010 or sign up for notifications through the Town's Notify Me feature at /list.aspx to see if there are any wood burning restrictions
- Abide by the "no wood burning" restrictions

You may check particulate emission (PM-10) levels on the GBUAPCD's Mammoth Lakes monitoring station website.
Particulate Emissions Regulations (Woodstove Ordinance) - Municipal Code Chapter 8.30
The Town's Particulate Emissions Regulations (Municipal Code Chapter 8.30) was revised on May 7, 2014 by Town Council.
Woodstove Replacement Programs
Almost 200 woodstoves have been replaced in Mammoth Lakes with funding through the Great Basin Unified Air Pollution Control District from 2012-2015. No funding is currently available.
Woodstove Replacement Program - Environmental Public Benefit (EPB) Funds
On August 6, 2014, the Town Council accepted $274,963 from the Great Basin Unified Air Pollution Control District for woodstove replacements. The Program is now closed. 145 woodstoves were replaced with cleaner burning systems under this Program.

Previous Woodstove Replacement Program (Clean Air Projects Program)
Under the Town of Mammoth Lakes' CAPP program, 21 woodstoves were replaced with more efficient and cleaner heating systems. An additional 28 woodstove replacements were completed in Mammoth Lakes through the Great Basin Unified Air Pollution Control District's CAPP program. These funds have been expended, and the CAPP programs are closed.
Air Quality Management Plan Update
On November 6, 2013, the Town Council adopted an updated Air Quality Management Plan (AQMP) or Air Quality Maintenance Plan and PM-10 Redesignation Request. This was subsequently approved by the Great Basin Unified Air Pollution Control District on May 5, 2014. An update to Municipal Code Chapter 8.30, Particulate Emissions Regulations, was also included in this effort. This work was funded by a grant from the Clean Air Projects Program (CAPP).
