Environmental journalists interested in knowing how they measure up have a new yardstick: a rating by the Department of Energy. In a report made public in early November, the DOE ranked reporters by how they treated the agency - a 100 score being most favorable. "As far as I'm concerned, if you have too good a rating, you aren't doing your job," said H. Joseph Hebert, an Associated Press reporter. His record-low score was 30.8. To see how your favorite reporters stack up in the tax-payer funded, $46,500 study by Carma International, contact the Department of Energy, Carmen MacDougall, Acting Director for Public and Consumer Affairs, Room 7A145 Forrestal Bldg., 1000 Independence Ave., SW, Washington, DC 20585 (202/586-4940).
