To comply with federal regulations set by the Environmental Protection Agency, the city of Anchorage, Alaska, is required to remove 30 percent of the solid material from their sewage water. But according to Paula Easley, director of public affairs for the city, "our water is so clean it's difficult to remove 30 percent. So we finally allowed our two biggest fish processors to dump their waste in our sewers so we could take it out again. It's ludicrous, but it saved us from building a half-billion-dollar plant."
