ARC 1988C
ENVIRONMENTAL PROTECTION COMMISSION[567]
Adopted and Filed
Pursuant to the authority of Iowa Code sections 455B.105 and 455B.173, the Environmental Protection Commission (EPC) hereby amends Chapter 61, “Water Quality Standards,” Iowa Administrative Code.
This rule making adopts by reference the updated and amended Surface Water Classification document which lists the use designations for Iowa streams. Stream redesignations are based upon the Department of Natural Resources (DNR) conducting a Use Assessment and Use Attainability Analysis (UA/UAA), which is a step-by-step process to gather site-specific field data on stream features and uses. The DNR then assesses available information to determine if the “presumed” recreational and aquatic life uses are appropriate. The listed amendments are the recommended designated use classifications for stream segments that have undergone the UA/UAA process.
The Surface Water Classification changes are summarized as follows:
1.	Class A1 Stream Segments

 	Stream Name	UAA ID	Basin	Class A1 Stream Segment Length (miles)	Aquatic Stream Segment Length (miles)

*Stream segments that were previously approved by EPC but omitted from the Surface Water Classification document.
The stream descriptions provided above are designed to provide clear notice to the public and may have nonsubstantive differences from the Surface Water Classification document. The Surface Water Classification document also contains nonsubstantive revisions to previously adopted stream designations to correct typographical or descriptive errors. All designations conform to the previously approved use designations, as amended by the Commission.
Notice of Intended Action was published in the Iowa Administrative Bulletin on February 18, 2015, as ARC 1877C. Two written comments on the proposed water quality standards revisions were received. A responsiveness summary has been prepared addressing the comments in terms of the issues involved. The comments did not result in changes to the proposed amendment. This amendment is identical to that published under Notice of Intended Action.
Additional information on Iowa’s Water Quality Standards and the Department’s rules can be found on the Department’s Web site at http://www.iowadnr.gov/InsideDNR/RegulatoryWater/WaterQualityStandards/Rules.aspx.
This amendment may have an impact upon small businesses.
A jobs impact statement (JIS) has been prepared for this rule making and is available upon request. The Department believes the rule making will not impact jobs since adoption of this amendment does not add to the burden or cost established by the 2006 rule making. Wastewater treatment facilities in Iowa, particularly local government-owned wastewater facilities, have been significantly impacted by the 2006 water quality standard revisions. This amendment will not add to the burden or cost established by the 2006 rule making but does allow for the implementation of those prior requirements. Based upon the number of facilities impacted by this amendment, it is estimated that between $46 million and $64 million will be spent on facility upgrades. These upgrades will be implemented upon approval of the renewed NPDES permit for the facility. These figures may change based upon other factors, including inflation and varying construction costs.
It is important to understand that by revising the stream designations to reflect the appropriate uses, rather than the presumed uses, the amendment does not increase the potential compliance costs for any necessary facility upgrades in any way. When compared to the costs of implementation of the presumed uses, the cost of implementing the revised designations will always be the same or less.
Additional information on Iowa’s water quality standards, including the JIS and detailed maps of the stream assessments, can be found on the Department’s Web site at http://www.iowadnr.gov/ InsideDNR/RegulatoryWater/WaterQualityStandards/DesignatedUses/UseAssessments.aspx.
This amendment is intended to implement Iowa Code chapter 455B, division III, part 1.
This amendment will become effective June 17, 2015.
The following amendment is adopted.
	Amend subrule 61.3(5) as follows:
	61.3(5) Surface water classification. The department hereby incorporates by reference “Surface Water Classification,” effective December 22, 2010 June 17, 2015. This document may be obtained on the department’s Web site at http://www.iowadnr.com/water/standards/index.html http://www.iowadnr.gov/ InsideDNR/RegulatoryWater/WaterQualityStandards/Rules.aspx.
