From the NY Post:
Federal aviation regulators ruled in 2005 that the city's proposed Queens trash-transfer station was more than twice as tall as rules allowed -- but reversed course amid city lobbying, documents show.
At 110 feet tall, it was 62 feet higher than allowed for a building less than a half-mile from La Guardia Runway 31, the Federal Aviation Administration ruled, labeling the plan a "presumed hazard."
Bloomberg-administration officials appealed, and in September 2006 the FAA OK'd the structure -- although the FAA admitted it was in a "protection zone."
The Port Authority soon gave up its opposition.
The FAA declined comment, and the PA did not respond to a request for comment.
