indicated in Chapter 173-475 WAC.
• ppm = parts per million• µg/m3 = micrograms per cubic meter• Annual Standards never to be exceeded, short-term standards not to be exceeded more than
once per year unless noted.
\\Please note: Primary standards are listed in this table as they appear in the federalregulations, ambient concentrations are rounded using the next higher decimal place todetermine whether a standard has been exceeded. The data charts in this report areshown with these unrounded numbers.

10 1996 Air Quality Data Summary
Visibility MonitoringEcology, in cooperation with the National Park Service and the U.S. Forest Service, monitorsvisibility conditions in Washington’s Class I areas during the summer months. Class I areas areareas that are given more stringent air quality protection than other areas of the state (seemap). Although monitoring is generally conducted from early June through late October, theperiod of most concern is July 4 through Labor Day. This “visibility protection period”coincides with the period of heaviest visitation to the Class I areas of the state.
Visibility monitoring for the 1996 season involved the operation of five nephelometer sites inwestern Washington. Sites operated were South Mountain, Paradise Visitor Center, CarbonRiver Ranch, Marblemount, and Hurricane Ridge (see map for site locations).
Data from these sites is presented in the graphs on pages 11-14.
