WASHINGTON — The U.S. Environmental Protection Agency announced plans Wednesday to require “green roofs,” rain barrels and other measures that trap runoff at new and redeveloped buildings in the District of Columbia, making the city a test case for an ambitious effort to stop pollution from flowing into rivers along with the rain.
The EPA plan would require developers to trap 90 percent of the water that falls on a plot during a storm. The EPA will seek comment on the plan.
