BOONE, Iowa—4th District Congressman Steve King was in Boone last week, part of a district wide tour over the Congressional Easter recess. King says he’s made over 300 visits to different cities in the new 4th District King says one of the common themes he’s heard has been the Iowa DNR imposed EPA regulations on nutrient reductions, specifically as they related to cities. King says he estimates the cost in the state could be as much as $1.5 billion. He pointed out that if the environmental improvements are justified by the expenditure, that’s one thing, but if it’s politically driven, that’s another. King said the issue is something that he will be looking into for more answers. The controversial Nutrient Reduction plan for Iowa earlier this year drew mixed responses because of the impact on municipalities and the agricultural industry.
