Introduction


Air Quality in the Mid-Atlantic Region

Air quality in the Mid-Atlantic Region is generally good, but ozone levels often become unhealthy in the summertime. Understanding what causes high levels of ozone in the air we breathe, and taking steps to prevent air pollution, are two of the most important duties of state and local air pollution control agencies in the Mid-Atlantic Region.

Ozone problems occur in broad, multi-state regions because summer weather patterns that help form ozone affect large areas, transporting ozone and the pollutants that cause ozone from one state to the next. Ozone affects both urban and rural areas, and t he highest levels of pollution often occur downwind of major urban areas.


About this Atlas

Maps in this Atlas show the Mid-Atlantic states and some of the area surrounding them. Data in charts and tables are presented primarily for the Mid-Atlantic states: Pennsylvania, New Jersey, Delaware, Maryland, the District of C olumbia, West Virginia, Virginia, and North Carolina.

This Atlas is intended to present basic information about ozone air pollution in the Mid-Atlantic Region. Comments and suggestions for future air quality analysis are welcome. Please direct comments to Ms. Susan S.G. Wierman, Executive Director, Mid-Atl antic Regional Air Management Association, 711 W 40th St., Suite 318, Baltimore, Maryland 21211-2109.


About MARAMA

The Mid-Atlantic Regional Air Management Association (MARAMA) is a cooperative association of state and local air pollution control agencies from New Jersey through North Carolina. With the support of the US Environmental Protecti on Agency, our mission is to strengthen the skills and capabilities of member agencies and help them work together to prevent and reduce air pollution in the Mid-Atlantic Region.


Acknowledgments

Production of this Atlas was made possible by a grant from the US Environmental Protection Agency, Office of Air Quality Planning and Standards. MARAMA extends its gratitude to Mr. William F. Hunt and the PAMS Data Analysis Team o f OAQPS, without whose support and participation this Atlas could not have been produced. Mr. Mark Schmidt of the PAMS Data Analysis Team provided invaluable support and produced most of the tables and many of the charts in the report.

MARAMA also acknowledges the contributions of Dr. Richard Reiss of Sonoma Technology, Inc., and Mr. Ted Erdman of EPA's Region III office in Philadelphia. Dr. Reiss produced the maps in this Atlas, and Mr. Erdman produced the PAMS summary table in Append ix E. The maps of ozone during July episodes in 1988 and 1995 were produced by Dr. Bret Schichtel of Washington University at St. Louis at the request of Mr. Todd Ellsworth of EPA Region III. Thanks are also due to Mr. Dick Wies of the State of Maryland's Depa rtment of the Environment and Mr. George W. Leney of the Allegheny County Pennsylvania Health Department, who also contributed to this report.

Production support was provided by Ms. Carolee DeWitt of Sonoma Technology, Inc. Susan Wierman, Executive Director of MARAMA, prepared the text and directed the production of this Atlas in cooperation with MARAMA's Air Quality Monitoring and Data Analysi s Committee. Elena Belyaev of MARAMA produced this web site with assistance of Rich Poirot of Vernmont.
