The EPA has harnessed Google Earth to give us the most detailed picture of point-source pollution ever: a Google Earth map showing every major power plant, oil field, petroleum refinery, chemical factory, cement manufacturer and paper mill in America. In short, it's a NIMBY dream. From the comfort of your home you can pull up the biggest smokestacks in the hood and imagine precise amounts of NOx, SOx, VOCs drifting down to your lawn. Fun, fun, fun!
Of course, the EPA probably hopes the fun will make you forget how it substantially weakened requirements that companies disclose toxic releases this year, and that it now offers significantly less public info in its popular Toxics Release Inventory reports. Earlier this month the GAO found that the EPA had been pressured to scale back the reports by the White House. The EPA had "expedited" the decision to satisfy the Office of Management and Budget, which wanted to reduce the paperwork burden on industry, the GAO found.
So take the maps with a grain of salt. Air, for the time being, still can't be Googled.
