Legislators will quickly act to ensure Iowa’s livestock regulations mimic the new federal E-P-A standards announced Monday. Senate Republican Leader Stewart Iverson of Dows says the feds modeled their new standards after Iowa’s law, but there must be a little tinkering to ensure Iowa livestock producers don’t have to follow two sets of regulations. He says they have a head start, since most of Iowa’s regulations mimic the federal guidelines.Iverson led the group of lawmakers who drafted new regulations this past spring, including a system whereby county officials can rate confinement applications on a number of factors, including social impact. The state official hired to monitor large-scale confinement rules says the changes needed to bring Iowa’s law in line with the new federal rules are minor, and involve speeding up the implementation of some standards, such as a rule on how much phosphorus may be applied to agland.
