HOUSTON (August 29, 2013)—The Texas Commission on Environmental Quality will start measuring air pollution levels near a Houston freeway as part of a federal requirement to monitor health risks near major roadways.
Beginning in January, the TCEQ will measure levels along U.S. Route 59, providing the state with its first data on pollution near congested freeways.
The Houston region is already one of the most heavily monitored areas in the country, particularly for smog, but the network has not included one near a freeway because the system is intended to measure air quality across a region, not a specific neighborhood.
That changed in March when federal regulators ordered the largest U.S. cities to install roadside monitors for nitrogen dioxide, a smog-forming pollutant released from tailpipes.
