HB 2252 strengthens air quality permit requirements for certain oil and gas facilities regulated by the Texas Commission on Environmental Quality (TCEQ). It prohibits TCEQ from adopting new or amended standard permits for such facilities unless the agency conducts a regulatory analysis, evaluates credible air quality monitoring data, and determines that emissions limits are necessary to protect public health and physical property. The bill also mandates that air quality modeling used in these decisions must be based on actual monitoring data rather than hypothetical worst-case scenarios unless the worst-case results are confirmed by real-world data​.
