May 22, 2025. Reno/Sparks, Nevada.  – Northern Nevada Public Health – Air Quality Management Division (AQMD) is requesting written comments from the public on its draft 2025 Ambient Air Monitoring Network Plan and its draft 2025 Ambient Air Monitoring Network Assessment.

Comments will be accepted until midnight on June 22, 2025, and may be submitted via e-mail to AQMDPlanning@nnph.org.

All correspondence must include the commenter’s first and last name and a complete mailing address.

Air Monitoring Network Plans are required annually by the U.S. Environmental Protection Agency (EPA).  The plan provides detailed information on the specific location of each monitoring station, siting criteria, monitoring methods and objectives, sampling frequency, 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 2025 plan is substantially similar to the 2024 Ambient Air Monitoring Network Plan. A summary of all completed and proposed changes can be found on pages 9 through 11 of the plan.

Air Monitoring Network Assessments are required every five years by the EPA. The primary objectives of the Network Assessments are to determine whether the network meets the monitoring objectives defined in Appendix D of 40 CFR Part 58. The assessments also evaluate whether new sites are needed, whether existing sites are no longer needed and can be terminated, and whether new technologies are appropriate to incorporate into the ambient air monitoring network. The 2025 Assessment is also substantially similar to the 2020 Assessment.
