DES MOINES, Iowa (AP) — Republican House leaders plan to introduce legislation that would fund water quality initiatives without the use of a sales tax set aside for education infrastructure. The proposal is an indication Gov. Terry Branstad’s proposal to merge the two efforts is dead this session. House lawmakers said Thursday the bill would use other revenue sources, and it could include money that typically goes to the general fund or dollars from a separate infrastructure fund. Ben Hammes, a Branstad spokesman, says the governor will work with lawmakers to find consensus and that he believes any water quality plan needs a long-term source of revenue.
