"I am pleased to report that thanks to your work and more importantly the great recyclers in your community, the amount of refuse processed at the MTS will be lower than anticipated during the planning process," Garcia said in a letter.

City Councilman Ben Kallos said the reduction of truck traffic on the Upper East Side is a positive sign that the city may scrap the plan entirely.

"We've spent four years fighting the Marine Transfer Station and pushing for a smarter way to handle our city's waste, which is already paying off with a 25% reduction in trucks and trash," Kallos said in a statement. "We must continue our fight to stop the Marine Transfer Station from opening, if it opens see it closed, and spend every moment reducing waste through diversion, such as reusing, composting and recycling."
