Again, going from memory of past discussions...
- There is language in the federal laws that prohibits restrictions beyond what the clean waters act requires. As I recall, it was Peggy Hall who pointed this out. If the states want more restrictive regulations, their only option is to petition for an NDZ. So a more restrictive law is indeed in conflict with federal law and therefore illegal.
- If the Vermont law accepted a disconnected hose as an ADDITIONAL form of compliance with the NDZ, I think that would be fine. But to require it as the ONLY form of compliance is again in conflict with federal law that lists other acceptable forms of compliance.
