The EPA Storage and Retrieval of Aerometric •) Data (SAROAD) format is the established medium for transmittal of air data to EPA Regional Offices within 45 days after each quarterly reporting period. EPA Regional Offices must, within an additional 30 days, forward data they have received to the EPA Aerometric and Emissions Reporting System (AEROS) of which the SAROAD system is an operational part. AEROS is managed by the National Air Data Branch, Monitoring and Data Anal- ysis Division of the Office of Air Quality Planning and Standards. Summaries of these data are provided to interested parties upon request. In a continuing effort to provide these data to participating agencies as well as to the public, EPA periodically publishes a summary of all data submitted. It is this Agency's desire that participating agencies take this opportunity to check these data to ensure that: (1) the data are correct and (2) the data accurately reflect the ambient air quality within each Air Quality Control Region (AQCR).

The data in this publication are being republished in the new revised format currently being used. Some of the data in this publication have been revised as a result of a recent effort to improve the quality of the past data. The most recent up-to-date SAROAD reports are available upon request from the National Air Data Branch or the appropriate EPA Regional Office. These locations are shown in the following table.

In the future NADB edit programs will reject any new data 3 submittals indicating a "not acceptable" analytical method. All exis- ting "not acceptable" data will be removed from the files and stored In SAROAD format. This "not acceptable" data will no longer be included in data retrieval files. ORGANIZATION AND FORMAT These data represent all acceptable ambient air quality data sampled for pollutants that currently have National Ambient A1r Quality Standards. These pollutants, along with their corresponding sampling intervals and National Primary and Secondary Standards, are as given on the following page. 3.

When submitted, both continuous and non-continuous sampling intervals are given. For uniformity, all summaries are shown in micrograms per cubic meter (ug/m ) except carbon monoxide, which is given in milligrams per cubic meter 2 (mg/m ). Note that the pages are printed so that individual sections (pollutant-method combinations) may be removed and inserted in a loose- leaf notebook if desired. The format employed in this publication provides both parametric and non-parametric indices of air quality. The number of observations, the minimum and maximum value measured for the period of record, and the odd deciles plus the 95th and 99th percentiles describe the distri- bution of observed values. The arithmetic and geometric means and standard deviations provide some measure of central tendency and dispersion. Each summary line is preceded by the A1r Quality Control Region within which the sampling site is located, the city or county (parish, election district, or regional planning district), the three-digit site number within the city or county, and an Agency Type Code that Indicates the type of agency responsible for the laboratory analysis. A Project Code 1s shown with the Agency Type Code to indicate the type of sur- veillance being conducted. Some principal Agency-Project Codes are: *0zone included. 4.

The arithmetic mean, geometric mean, alrthmetlc standard devi- ation, and geometric standard deviation are calculated and summarized 1n this report for data having met these criteria. Reports are available from the National A1r Data Branch or the appropriate EPA Regional Office which give the means and standard deviations even though the minimum sum- mary criteria are not satisfied. Criteria for continuous observations with sampling Intervals of less than 24 hours are as follows: xi image: ------- Data representing quarterly periods must reflect a minimum of 75 percent of the total number of possible observations for the applicable quarter. Data representing annual periods must reflect a minimum of 75 percent of the total number of possible observations for the applicable year. Criteria for non-continuous observations with sampling intervals of 24 hours or greater are as follows: Data representing quarterly periods must reflect a minimum of five observations for the applicable quarter. Should there be no measurements in one of the three months of the quarter, each remaining month must have no less than two observations re- ported for the applicable period. Data representing annual periods must reflect four quarters of observation that have satisfied the quarterly criteria.
