The mission of the Environmental Protection Agency (EPA) is to protect human health and the environment. In 2013, EPA created the Trash Free Waters program, a non-regulatory program that works through robust partnerships to reduce the volume of trash entering the nation’s waterways. The program works closely with other offices within EPA to help affect positive change with respect to reducing the amount of trash entering the environment. These offices include the Office of International and Tribal Affairs, which leads EPA’s international engagement on marine litter policy; the Office of Land and Emergency Management, which covers solid waste management, recycling, resource efficiency and sustainable materials management; and the Office of Research and Development, which conducts and supports macro- and microplastics and other related research.
