EPA comments on IA nutrient reduction strategy

January 14, 2013  by Press release

January 14, 2013, Lenexa, KS – U.S. EPA Region 7 is providing comments on the draft Iowa Nutrient Reduction Strategy released Nov. 19, 2012.

Karl Brooks, regional administrator, in a letter commends the Iowa Department of Natural Resources (IDNR) and Iowa Department of Agriculture and Land Stewardship (IDALS) for developing the strategy that embraces ambitious specific nutrient reduction targets.

“The EPA views the draft Iowa Nutrient Reduction Strategy as a great start to set in motion actions that will begin to yield measurable nutrient pollution reductions from point and nonpoint sources,” said Brooks. “EPA looks forward to working collaboratively with IDALS and IDNR on implementation of the strategy to achieve our mutual goals of water quality improvement in Iowa.”

Iowa based its draft strategy on the EPA’s 2011 memorandum that dealt with how states should achieve long-term reductions in nitrogen and phosphorous pollution in water bodies.


Brooks’ letter notes that the EPA supports states leading efforts to reduce nutrient loads from point and non-point sources but stresses the EPA is not mandating specific strategies or solutions. The draft strategy raised concerns about the EPA’s eco-regional criteria published in 2000. Since then, the EPA and some states have identified a range of options that can be appropriately used for development and implementation of numeric nutrient criteria.
