Analysis of ozone precursor data from Baton Rouge, Houston, El Paso, and Dallas
- Environmental Protection Agency, Dallas, TX (United States). Multimedia Planning and Permitting Div.
Ongoing analyses of ozone precursor data continue to be performed for Baton Rouge, Louisiana, and Houston, El Paso, and Dallas, Texas. All four areas have collected ambient monitoring data for ozone, nitrogen oxides (NO{sub x}), and over 50 volatile organic compound (VOC) species in accordance with the Photochemical Assessment Monitoring Stations (PAMS) requirements. The PAMS program was initiated to provide more detailed VOC, NO{sub x}, and meteorological data for scientists, modelers, and managers working toward eliminating violations of the ozone National Ambient Air Quality Standards (NAAQS). This paper will focus on several useful analyses of PAMS data for the four study areas including: (1) a trends analysis of Total Non-Methane Organic Compounds (TNMOC), NO{sub x}, and ozone data from two Baton Rouge sites, (2) results of TNMOC/NO{sub x} ratio analyses for the three Baton Rouge PAMS sites which can provide a starting point for evaluating specific site sensitivity to changes in VOC or NO{sub x} ambient concentrations, (3) results of benzene/toluene ratio analyses which supply information on aged/fresh air masses, and (4) results of ethylene/acetylene ratio analyses which are useful in determining the impacts of catalytic/noncatalytic vehicles. This paper will also discuss the continuing maturation of the PAMS program in Baton Rouge, Houston, and El Paso. The Dallas area is expected to formally begin implementing a PAMS program in 1998 after the area is reclassified to a serious status for ozone pollution. In addition, the Beaumont, Texas area is currently scheduled to be reclassified to a serious status for ozone pollution in the 1998/1999 time period, and thus would also need to begin implementing a PAMS program.
