Minnesota regulators can now adopt new ‘clear car’ rules without getting legislative approval.  On Friday, a judge ruled that the state Pollution Control Agency could write new rules requiring manufacturers to deliver more electric and hybrid cars to Minnesota lots.  Republican lawmakers and auto dealers objected to the ‘clean cars’ plan, saying such regulations should come from the Legislature.  But, the ruling says the MPCA has the clear authority to adopt rules that address air pollution.  Officials say the rules, similar to ones in California and other states, will give buyers more options.
