About PlanetHazard
PlanetHazard has mapped over 86,000 companies throughout the United States that emit hazardous air pollutants and criteria air pollutants. We have done this so that you can learn what companies are releasing into the air in your area. You may search this site nationally or by state, county, city and/or company. All pollutant data used on this site is from the Environmental Protection Agency National Emission Inventory Database and is current as of the most recent release, 2002. (This is preliminary data - the last official release was in 1999.)
