An Iowa Senate subcommittee has approved a bill it hopes will improve water quality by tightening manure application laws.

Sen. Joe Bolkcom (D-Iowa City) from the Natural Resources and Environment Subcommittee introduced the bill last month. If passed, the bill would bar farmers from applying fertilizer when (1) the ground is frozen or snow-covered; (2) the ground is water-saturated; (3) the 24-hour weather forecast calls for a half-inch of rain or more; or (4) the ground is sloped at 20 percent or greater. The currently law – which was added to the Iowa Code in 2010 – states that farmers cannot apply fertilizer to their soil between December 21 and April 1.

The proposed bill is also supported by the non-profit Iowa Citizens for Community Improvement. ICCI organizer Jess Mazour believes the proposed bill will be more effective at cleaning up Iowa’s waterways compared to the current voluntary system.

“It is very much needed because voluntary compliance is not working,” Mazour said in an interview with WNAX. “And if we just leave it up to farmers to pick and choose what they think is safe it’s showing us that our water is just going to keep getting dirtier. We have to be very specific about what we want.”

An identical bill was also introduced to the Iowa House by Rep. Dan Kelly (D-Newton). These proposals come on the heels of a recent measure drafted by the Iowa Department of Natural Resources and the U.S. Environmental Protection Agency which allows the DNR to inspect manure-handling practices by farmers and to issue fines for those not in compliance with current codes.

Approximately 76 manure spills were reported in 2013. In 2014, a dairy farm was fined $160,000 after improper manure disposal killed hundreds of thousands of fish.
