Relating to monitoring air contaminant emissions in certain counties.

HB 826 requires the Texas Commission on Environmental Quality to install and maintain air quality monitors in specific counties containing coal-fired power plants and adjacent to counties with populations of 3.3 million or more. The monitors must track pollutants listed on the state's air pollutant watch list and collect real-time data, which the commission must post online. Each year, the commission must publish a report analyzing whether pollution levels exceed national air quality standards and suggest health-protective actions. This bill directly affects counties meeting both geographic and industrial criteria, focusing on transparency and data collection for public health monitoring. The requirements take effect September 1, 2025.
