10/21/98 METT Memorandum

EPA memo outlining acceptable methods for I/M program evaluations (PDF) (51K)   The memo was noncommittal on the issue of using Remote Sensing as EPA felt additional work was needed to fully understand the benefits and disadvantages of the technique.  Toward that end, EPA has been working with the Coordinating Research Council Remote Sensing group to address the Agency's concerns.
