Facility/Monitor Locator Map -
criteria air pollutants

A Facility/Monitor Locator map shows the locations of criteria air pollutant point sources (facilities) and air monitoring sites (monitors). A map may include either facilities or monitors, or both. The map has a symbol at the latitude-longitude coordinates of each facility and monitor. Map shading indicates the states or counties in which facilities or monitors are located. You may also elect to show geographic features such as city names, national parks, and highways.
