Annual Monitoring Network Plan and Five-Year Assessment of TCEQ Air Monitoring Network
Historical air-monitoring network plans and EPA responses.
Under the requirements of 40 Code of Federal Regulations Part 58, TCEQ reviews its air monitoring network each year and creates an annual monitoring network plan (AMNP) to demonstrate how Texas is meeting or will meet federal air monitoring requirements. The AMNP includes proposed changes from the previous year and future proposed changes to the monitoring network. In addition, TCEQ conducts a broader analysis of the monitoring needs in Texas every five years since 2010. This five-year assessment (FYA) evaluates changes in population, emissions sources, and design values to determine whether individual monitors within the network should be added, moved, or decommissioned to best understand and evaluate air quality with existing resources.
Both the AMNP and FYA discuss the specific air monitors that are used to meet federal air quality standards. Because the AMNP and FYA are focused on federally required monitoring, they do not include a review of state-initiated monitoring that is conducted in addition to federal requirements
TCEQ posts the AMNP and FYA for 30 days to solicit public comment. The AMNP and any comments received are submitted to EPA by July 1 of each year for review and approval. FYAs are submitted to EPA by July 1 every five years. Recent AMNPs and the latest FYA, including TCEQ responses to public comments and EPA responses, are available below in PDF format.

State-Initiative Air Monitoring Network Updates
TCEQ also operates a robust network of state-initiative air quality monitors that support a variety of purposes. State-initiative air quality monitors can provide information for assessing public health and studying air pollution formation and behavior. Beginning with 2024, an annual summary is provided to document changes to TCEQ-owned, state-initiative air quality monitors and/or sites not discussed in the AMNP or FYA. The annual state-initiative update summary will be published in August for the previous calendar year.
The latest information regarding the entire Texas air monitoring network of federal and state-initiative monitors, monitoring data, and air quality forecast conditions for Texas’ metropolitan areas is featured on the TCEQ webpage Air Quality & Monitoring.
