Denver (AP) Lawmakers have given final approval to a bill giving state agriculture officials the right to inspect large tanks of anhydrous ammonia that farmers use for fertilizer.
The house approved the measure on Monday. It now goes to the governor.
Republican rep. Jerry Sonnenberg of Sterling, the bill sponsor, says anhydrous ammonia is one of the most toxic chemicals used by farmers. He says it can freeze the lungs if it leaks, and it's become a target for methamphetamine makers.
Sonnenberg says the state already has the authority to inspect 500-gallon tanks. This bill expands the authority to tanks of up to 2,000 gallons.
Democratic Rep. Wes McKinley of Walsh says the bill is too broad.
