Georgetown University has lobbed another grenade in the bitter war to win approval to build a cogeneration power plant on its campus. For the last few weeks, in an effort to attract public support for the vigorously opposed project, the university has placed four-page inserts—“Our Case for Cogeneration”—in five community newspapers that serve Georgetowners. Since the university announced plans for the facility in 1988, neighborhood opponents, citing environmental dangers, have stalled the project with appeals to myriad government boards and agencies. Georgetown’s slick-looking insert contains a prepaid postcard—a reader-response tactic that Georgetown hopes will reveal community support for the plant. According to spokesman Gary Krull, of 250 postcards sent back to the university, 54 percent favor and 30 percent oppose the plant, a ratio Georgetown will emphasize when it seeks final building permits this fall. But a leading plant opponent, Dianne Sayawa, dismisses the public relations campaign, calling it a “desperate…and misleading” ploy to sway Washingtonians who oppose the plant.
