Bill Summary
This bill relates to water quality of surface waters of the state (Code section 455B.171(41)) under the federal Clean Water Act (CWA), which includes a series of public laws codified in 33 U.S.C. §1251 - 1376. Section 303 of the CWA (33 U.S.C. §1313) establishes water quality standards for states. States must establish a priority ranking of waters of the state that have been impaired according to total maximum daily loads (TMDL) of pollutants as established by the United States environmental protection agency (EPA) (40 C.F.R. §130.7(b)(4)). Every two years, the department of natural resources (DNR) compiles a list of the state’s impaired waters (303(d) list) for approval by EPA. State statute requires DNR to use credible data when determining whether any water of the state is to be placed on or removed from the section 303(d) list (Code sections 455B.193 through 455B.195). The bill provides that if, in compiling a 303(d) list, DNR determines that pollution is attributable to fecal bacteria, it must designate by percentage each species of animal, if any, that has contributed to the impairment.
AI Summary
This bill requires the Iowa Department of Natural Resources (DNR) to conduct a specific analysis before listing a water body as "impaired" due to high levels of fecal indicator bacteria, which are microorganisms often used to indicate the presence of harmful bacteria from animal waste. Specifically, if the DNR finds that fecal bacteria are causing pollution, they must use methods like microbial source tracking to determine and assign a percentage to each animal species that has contributed to the problem. This process is part of the state's responsibility under the federal Clean Water Act (CWA) to identify and address waters that don't meet water quality standards, a list that is updated every two years and submitted to the U.S. Environmental Protection Agency (EPA) for approval.
