Where the US government pretends that water does not flow. So, if you pollute a stream, the pollution will not reach the lake the stream flows into.
The landmark U.S. law to fight water pollution will now apply only to bodies of water large enough for boats to use, and their adjacent wetlands, and will not automatically protect streams, the U.S. government said on Tuesday.
Environmental groups said they fear the new policy will muddy the purpose of the federal Clean Water Act and put many smaller bodies of water at risk. Democrats in Congress have introduced legislation mandating protection of creeks, estuaries and other watersheds.
This is the right approach, the word “navigable” needs to struck from the legislation. Pollution control has nothing to do with navigation, it is about watershed protection.
