PA Environment Digest Blog – To prevent litter from ending up in our waterways, Keep Pennsylvania Beautiful urges Pennsylvania residents to participate in Pick Up Pennsylvania, in support of the Ocean Conservancy’s International Coastal Cleanup. This annual event is an opportunity to improve neighborhoods and Pennsylvania’s waterways by coordinating or participating in a litter cleanup. Registration is now open. This year’s program runs from September 1 through November 30. During this period, registered events can get free trash bags, gloves, and safety vests provided by the Department of Environmental Protection, PennDOT and the Ocean Conservancy, as supplies last.
