Ozone concentrations in El Paso, Texas
- Texas Air Control Board, Austin
El Paso, Texas may have a problem in meeting ambient air standards due to influx of pollutants from foreign sources. Cd. Juarez, Chihuahua, and Fort Bliss abut the city and are areas over which the Texas Air Control Board (TACB) has little or no jurisdiction. The Board maintains two Continuous Air Monitoring Stations (CAM) in El Paso. Ozone, nitric oxide, and nitrogen dioxide data were obtained from these stations. If the EPA Empirical Kinetic Model is used for El Paso, reducing NMHC concentrations may increase rather than decrease O/sub 3/ concentrations. The Texas State Implementation Plan, while not based on Empirical Kinetic Modeling, calls for a reduction of 18% in NMHC. However, 31% of all NMHC in El Paso arise from sources over which Texas had little (a federal military reservation) or no (Cd. Juarez) jurisdiction. It appears the TACB is correct in believing the SIP for O/sub 3/ may not bring El Paso into compliance. (JMT)
