The Idaho House has failed to advance a bill that would have declared some restrictions handed down by the Environmental Protection Agency as unconstitutional.
The bill on Tuesday was returned to the Natural Resources and Conservation Committee, likely killing its chances of passage as this session winds to a close.
Rep. Paul Shepherd, a Republican from Riggins, had touted his bill as a way for Idaho to disregard many federal regulations on air and water pollution.
In particular, his bill would help dredge miners in his district whose work was impeded by what they call the EPA's unnecessarily restrictive water pollution rules.
The bill was met with deep skepticism from lawmakers who questioned its legality.
