Washington State's 2014 Water Quality Assessment (WQA) is produced in the Environmental Protection Agency's "Integrated Report" format. The WQA consists of both the 303(d) List and the 305(b) Report. The 303(d) List is comprised of only Category 5 listings. The EPA has determined that the freshwater 303(d) listings in the Current Assessment fulfill Washington State's requirement to submit an updated list of impaired freshwaters in 2012 since Washington State's 2012 Water Quality Assessment contained both marine and freshwater listings, but updated only the marine 303(d) listings. The 305(b) Report lists all waters and all categories. The 2014 WQA is presented on the 1:24k National Hydrography Dataset (NHD).
