Washoe County Health District Seeks Comment on Annual Ambient Air Monitoring Network Plan

May 26, 2023

Reno/Sparks, Nev. May 26, 2023 – The Washoe County Health District – Air Quality Management Division (AQMD) is requesting written public comment on its draft 2023 Ambient Air Monitoring Network Plan, an annual report which provides a detailed description of how and where air pollution is monitored in Washoe County.

Air Monitoring Network Plans are required by the U.S. Environmental Protection Agency (EPA). The plan provides the specific location of each monitoring station, siting criteria, monitoring methods and objectives, frequency of sampling, pollutants measured at each station, and aerial photographs showing their physical location. It also summarizes network modifications completed over the last 12 months and proposed network modifications over the next 18 months.

The 2023 plan is substantially similar to the 2022 Ambient Air Monitoring Network Plan except for the proposal to begin monitoring at a new station in Verdi and discontinue monitoring at an existing station in South Reno. A summary of all proposed changes may be found on pages 10 and 11 of the plan.

The County’s air monitoring network includes seven locations within the county: Incline, Lemmon Valley, Reno4, South Reno, Spanish Springs, Sparks, and Toll.  One or more of the following pollutants are measured at each site:  carbon monoxide, oxides of nitrogen, ozone, sulfur dioxide, PM10, and PM2.5.

Comments will be accepted until midnight on June 25, 2023, and may be submitted via email to


All correspondence must include first and last name and a complete mailing address.
