Most of the scare stories about the effects of Japan's earthquake, tsunami, and Fukushima disaster have been about radiation reaching our West Coast. I've not yet seen any credible scientist or official identify this as a genuine problem.
However, there is a real problem in which it looks like Federal emergency aid will be required: some of what was taken by the tsunami floats, and the ocean is delivering that stuff along the West Coast. Some of it would be hazardous to local marine ecosystems.
A 66-foot dock arrived near Newport, OR in May. It was covered in exotic seaweed and other organisms (starfish, cockles and mussels?) that were considered to be invasive species. Volunteers burned them off the dock. Now the dock itself has to be removed from the beach.
Boats arrived early on. Balls have already washed up and been returned to Japan. Pieces of houses have been reported by observers at sea.
West Coast needs federal help with tsunami debrisQuote:
It’s just the beginning. The main debris field is still far offshore, and flotsam is expected to keep washing up for years. Japanese officials estimate that 1.5 million tons of debris is floating in the Pacific Ocean; although some it will sink, much of it will end up on West Coast beaches. [5 million tons of debris were estimated to have been washed to sea, but much of that has sunken to the ocean floor.]
Most of the debris is manageable now, but that may not continue to be the case. Oregon is already experiencing a problem that challenges its resources – that aforementioned floating dock, which came ashore near the Central Oregon community of Newport. Hitching a 5,000-mile ride on the dock: about 2 tons of living creatures, including several species considered invasive and a threat to local sea life populations.
See also NPRThere have been suggestions from some kindly souls that Japan should be billed for the clean-up costs, which I view as extremely tacky. This was a natural disaster of epic proportions. Nobody argued for billing Indonesia for the clean-up costs of the Boxing Day tsunami. Were radiation to become a real problem, I might rethink that because it is evident that Japan's lax enforcement policies played a very large role in the damage to the Fukushima reactors.
House Republicans may insist that if California, Oregon, and Washington receive Federal emergency assistance, compensating cuts must be made elsewhere.

Asking Japan to pay for the clean-up costs would open wide the barn door for assertions that developing countries being affected by climate change should bill the industrialized nations of the 19th century for their losses and costs, on the "polluter pays" principle. A weak form of this is already in effect in the grants available from the UN to help developing countries adopt "green technologies." Most of that money stays with the industrialized nations, of course.
