IMPACT OF PM2.5 ON VISIBILITY The procedure for making personal observation to estimate the PM2.5 level for local areas without official monitors is: 1. Face away from the sun. • Determine the limit of your visible range by looking for targets at known distance (miles). • Visible range is that point at which even high contrast objects totally disappear. 3. Use the values above to determine the local PM2.5 level and health category. AWMA SE Regional Conference - 2008
Premature death; Respiratory related hospital admissions and emergency room visits; Aggravated asthma; Acute respiratory symptoms, including aggravated coughing and difficult or painful breathing; Chronic bronchitis; Decreased lung function that can be experienced as shortness of breath; Work and school absences; Greatly reduced visibility.

EPA AMBIENT AIR QUALITY STANDARDSAnnual Average 15ug/m3Daily Average reduced from 65ug/m3 to 35ug/m3 • Save 15 000 lives per year; • Reduce hospital admissions by thousands each year due to reduced heart and lung diseases; • Improved visibility. AWMA SE Regional Conference - 2008

Treats the dust prior to entering the Electrostatic Precipitator Uses fluidic (FAP) and electrostatic (BEAP) forces to attach the fine particles to the larger, easily collected particles The Bi-Polar Charger charges half the dust positively and the other half negatively Fine negative particles are selectively mixed with the large positive particles and large negative particles with fine positive particles When a fine particle comes close to an oppositely charged large particle, it is attracted and attaches to the large particle How Does The Indigo FPCSystem Work?
