SOLVE's annual beach clean-up event drew more than four thousand volunteers to Oregon's coast this year. They retrieved more than 52,000 pounds of trash.
SOLVE spokeswoman Briana Groodwin says tsunami debris from Asia continues to pop up on the beaches.
"We've been seeing a lot more of the same types of debris, just more of it - especially styrofoam and buoys. We've also been seeing a lot of lumber recently. It has notches in it and that's their traditional Japanese building style."
Congresswoman Suzanne Bonamici has made plans for a Monday announcement of a new bill she says would allow Oregon and other states to apply for cash to reimburse the cost of tsunami debris clean-up efforts so far.
Bonamici's spokesman says the National Oceanic and Atmospheric Administration received $5 million from the Government of Japan to assist with cleanup activities, but the agency can't spend it on clean-ups that have already occurred, such as the dock fragment that washed up in Newport last year.
