The District’s 5-cent bag tax generated about $150,000 during January to help clean up the Anacostia River, even though residents have dramatically scaled back their use of disposable bags.
In its first assessment of how the new law is working, the D.C. Office of Tax and Revenue estimated that food and grocery establishments gave out about 3 million bags in January. Before the bag tax took effect Jan. 1, the Office of the Chief Financial Officer had said that about 22.5 million bags were being issued each month in 2009.
