This pilot project has succeeded in retrofitting five gas compressor engines with controls that reduced NOx emissions from those engines by greater than 90 percent. The positive conclusion of this project has resulted from the cooperation of local stakeholders, the selection of a highly effective control technology and carefully planned and executed emissions testing procedures. This report documents the design, implementation and results of the compressor retrofit pilot project. http://www.netac.org/pdf/reports/air%20quality/2004_high_ozone_memo.pdf http://www.netac.org/pdf/reports/air%20quality/2004_high_ozone_memo.pdf Northeast Texas, while no longer in violation of EPAs ambient air quality standard for ozone, continues to experience days during the warm weather season on which ozone concentrations exceed levels designated by EPA as unhealthy for sensitive groups. In addition, recent data indicate that a violation of the ozone standard remains a possibility if the area were to experience a string of unfavorable weather conditions during upcoming ozone seasons. As a result, understanding the conditions associated with, and likely causes of, recent high ozone events in this area remains of central importance to state and local air quality planners. This memo presents our analysis of factors contributing to nine high ozone events observed in NE Texas during the 2004 season. For each day, we analyzed hourly ambient air quality and meteorological data, computed back trajectories and collected day-specific emissions data from major sources in the region. We begin with a brief summary of recent ozone trends and a summary of peak ozone concentrations during the nine days included in our analysis. This is followed by a detailed discussion of the conditions during each day. A summary of results and our conclusions are presented in the final two sections of this memorandum. http://www.netac.org/pdf/reports/air%20quality/netac_2002_emissions_report.pdf http://www.netac.org/pdf/reports/air%20quality/netac_2002_emissions_report.pdf This document presents the 2002 emissions innventory for reactivive volatile organic compounds (VOCs) oxides of nitrogen (NOx) and carbon monoxid (CO) from point, area, on-road mobile, non-road mobile, and biogenic sources for the core counties and major sources for perimeter counties in the Tyler/Longview/Marshall Flexible Attainment Region. Also provided are the 2002 stationary point source data from the Louisiana DEQ website for Caddo, Bossier and DeSoto Parishes. http://www.netac.org/pdf/reports/air%20quality/5th_biannual_report_eac.pdf http://www.netac.org/pdf/reports/air%20quality/5th_biannual_report_eac.pdf The report covers the background of the EAC, gives a status report on the implementation of the EAC, reviews the ozone attainment status, and lists all NETAC meetings and committee members.
