Topsoil a Dirty Subject

Topsoil became a dirty subject for conservationists arguing to retain 4" of topsoil after new development construction and developers who say it's simply too expensive. One of the reasons for the topsoil restoration rule is to help increase water infiltration into the soil, to prevent runoff and erosion, to retain healthy soil and to lessen the degradation of water quality. Topsoil retention will aid the homebuyers in their efforts to establish landscaping on their lots – grass, trees and gardens.

The EPC at its September meeting directed the DNR to commence rulemaking on the issue after accepting a stakeholder group's recommendation on preserving topsoil would modify a general permit requiring topsoil preservation for construction sites that disturb one acre or more adopted in the fall of 2012. The current rule calls for retaining four inches of topsoil spread on the surface, unless infeasible. The rulemaking process generally takes several months to complete and includes an opportunity for the public to submit comments.

Concerns about high costs of implementing the rule arose in 2013. A stakeholder group was organized in accordance with Executive Order 80, signed by Gov. Branstad in 2012, that requires rulemaking authorities to work with those who will be affected by new regulations. The governor claimed at its signing that executive order is about injecting common-sense into the regulatory process.

Not all Iowans would agree that the topsoil stakeholder group injected common sense into the process since the majority of the group's members are involved with new development construction. Members of the topsoil stakeholder group included Pat Sauer, Iowa Storm Water Education Program; Creighton Cox, Home Builders Association of Greater Des Moines; Joe Pietruszynski of Hubbell Realty; Chip Classon, Jerry’s Homes; Lucy Hershberger, Forever Green Inc.; Mark Watkins, McAninch Corporation; and Chad Ingels, member of the Environmental Protection Commission.

Sierra Club Iowa Chapter wrote to DNR Director Chuck Gipp in April 2014 requesting that he expand the stakeholder group membership to include additional stakeholders who are interested in protecting water quality and restoring the soil to a site so that the normal ground water functions are returned. Gipp ignored the Chapter request.

Sierra Club Iowa Chapter Applauds New Clean Water Rule to Restore Protections to Small 
Streams and Many Wetlands; Urges Protections for All Waters 

The Environmental Protection Agency (EPA) and the Army Corps of Engineers (Corps) 
proposed to restore historic Clean Water Act protections to hundreds of thousands of miles of streams 
and millions of acres of wetlands. When this policy is finalized, streams and wetlands that directly 
influence the water quality of our nation’s rivers, lakes and bays will once again be protected from 
pollution and destruction. 

“This proposed rule is long overdue and will benefit millions of people across the country and in Iowa,” 
said Neila Seaman, Iowa Chapter director. “The rule is a critical step toward protecting streams and 
wetlands that feed our drinking water supplies, filter pollutants and safeguard communities from 

For the past decade, there has been confusion over which streams and wetlands are covered by the 
Clean Water Act because of U.S. Supreme Court decisions and EPA policies. This confusion has put the 
drinking water of over 117 million people at risk. One in three Americans relies on public drinking water 
supplies that are fed by headwater or seasonally-flowing streams. For example, in Iowa 61 percent of 
streams are headwater or seasonal, feeding the drinking water supplies of 100 percent of Iowans.

While this rule would restore Clean Water Act protections to all streams and most wetlands - it would 
actually shrink – not expand – Clean Water Act protections compared to the historical scope of the Clean 
Water Act prior to a 2001 Supreme Court decision. The proposed rule also preserves existing 
exemptions for farming, mining, and other land use activities. 

“We will urge the Obama Administration to finalize a strong rule to restore protections to all water, 
including seasonal wetlands and other waters,” said Debbie Neustadt, Iowa Chapter chair. “Every water 
body is important and a strong rule will improve the health of our nation’s rivers, lakes, and bays, which 
depend on the smaller water bodies that feed into them.”

Iowa Nutrient Reduction Strategy

The Iowa Department of Agriculture, Department of Natural Resources and Iowa State University released its Iowa Nutrient Reduction Strategy.  The strategy is supposed to include plans for reducing the amount of Nitrogen and Phosphorus that flow from the Mississippi River watershed into the Gulf of Mexico, where the pollutants contribute to the dead zone.

The strategy, however, addresses a reduction in Nitrogen and Phosphorus resulting from non-point sources (primarily agriculture) by voluntary compliance, more research and additional technology.

DNR responds to EPA informal investigation on permitting


UPDATE: The EPA has posted its draft work plan agreement with the Iowa Department of Natural Resources.  See the draft agreement.

On September 11, 2012, the Iowa Department of Natural Resources (DNR) issued its response to the Environmental Protection Agency’s (EPA) July 2012 informal investigation of the DNR’s animal feeding operations permit program (see article below).  

DNR has agreed in its response to include:

  • Commencing the rulemaking process by November 1, 2012

  • Recommending an additional 13 full-time employees and associated funding for fiscal year 2014

  • Revising its Environmental Management System (EMS) and associated enforcement documents to properly account for penalty calculations and submit to EPA by January 31, 2013

  • Including better documentation in its files on what is witnessed during inspections

  • Pursuing the planned rule modifications as part of the rulemaking regarding NPDES permitting for confinements described in the EPA report. The DNR will also update nutrient management plan templates and application forms

  • Revising its construction permit application form to include the predictive modeling requirement

Environmental Protection Agency Report Validates Local Activists Complaint That Iowa DNR Has Failed To Adequately Regulate Factory Farm Water Pollution

On July 12, the federal Environmental Protection Agency (EPA) released a long-awaited report, finding that critical elements of Iowa’s program to regulate water pollution from factory farms, or “Concentrated Animal Feeding Operations” (CAFOs) fail to meet minimum federal requirements.  The report is a response to a petition filed in September 2007 by Iowa Citizens for Community Improvement (Iowa CCI), Environmental Integrity Project (EIP) and the Sierra Club, which alleged widespread failures to regulate illegal factory farm discharges and asked EPA to withdraw Iowa’s authority to run the state’s Clean Water Act permitting program. 

EPA’s findings include:

  • Iowa DNR does not issue permits to factory farms when required by the Clean Water Act.  

  • Iowa DNR does not have an acceptable system to figure out which factory farms need Clean Water Act permits in the first place, and has an inadequate inspection program.

  • Iowa DNR failed to act in response to CAFO Clean Water Act violations or failed to follow its own response policy in nearly half of cases reviewed by EPA.

  • Iowa DNR does not assess adequate penalties following CAFO violations of the Clean Water Act.

In a ruling March 31, 2012, Polk County District Court Judge Mary Pat Gunderson ruled in favor of the environment and water quality. 

“After more than 30 years, this antidegradation rule finally brings Iowa into compliance with the Clean Water Act,” said Wallace Taylor, the Sierra Club Iowa Chapter Legal Chair.  "This rule was the product of almost three years of effort by the Department of Natural Resources working with the regulated community and environmental organizations to adopt a rule that is fair.”

A lawsuit, brought by the Iowa Farm Bureau Federation (Farm Bureau), Iowa Renewable Fuels Association (IRFA) and Iowa Water Environment Association (IWEA), contended that an Environmental Protection Commission voted to approve a rule that will improve the quality of Iowa’s water resources is invalid because one of the commissioners had a conflict of interest and that another one wasn’t qualified to vote because she had recently moved out of state.  The lawsuit also asserted the rule is more stringent than federal law because it protects Outstanding Iowa Waters.

Judge Gunderson ruled that although then-commissioner Carrie LaSeur, who had moved to Montana prior to the December 2009 vote, was not an elector of the state of Iowa as required by statute when she voted on the antidegradation rule, it didn’t matter because when LaSeur’s disqualification is simply a technical infirmity that does not go to the heart of her duties and her actions are valid.

The Farm Bureau, IRFA and IWEA claimed the rule is invalid, in part, because one of the Commissioners is a water quality advocate for one of the organizations that petitioned the EPC for rulemaking.  Judge Gunderson ruled that “Susan Heathcote [who served on the commission in 2009] did not have a conflict of interest because the antidegradation rule finally adopted was not the one IEC, Sierra Club and Hawkeye Fly Fishing Association submitted [for rulemaking in 2007]; because she had no direct financial stake in the outcome; because the legislature established the EPC so commissioners would have expertise in certain areas; and because the Iowa Ethics and Campaign Disclosure Board cleared her for conflicts.”

Outstanding Iowa Waters protection also was victorious in today’s decision.  Judge Gunderson ruled that the protections may or may not be more restrictive than the federal rule, but the EPC substantially complied with the notice requirement.

The Environmental Protection Agency approved Iowa’s Antidegradation rule and Antidegradation Implementation Procedure in September 2010.

Judge Rules Against Iowa Farm Bureau  

On October 13, Polk County District Judge Brad McCall ruled that the Iowa Environmental Council (IEC) would not be required to hand over internal emails concerning the antidegradation rules to the Iowa Farm Bureau, the Iowa Renewable Fuels Association and the Iowa Water Environment Association as part of the three organizations’ lawsuit against the Iowa Department of Natural Resources and Environmental Protection Commission. The Iowa Farm Bureau and the other organization sought the emails to determine if Susan Heathcote, IEC’s Water Program Director, had used her position as an Environmental Protection Commission member to push the rule’s passage. The judge ruled that Iowa Farm Bureau, Iowa Renewable Fuels Association and Iowa Water Environment Association had enough material from IEC to prepare their case. EPC and DNR filed a Motion for Summary Judgment asking that the case be decided in their favor without a trial. The judge ruled that Farm Bureau and its allies have until November 4, 2011, to file papers letting him know why the case should proceed to trial.  Read the ruling.


Triennial Review Draft Work Plan Now Available 

Earlier this year, the Iowa Department of Natural Resources (DNR) sought Iowans’ thoughts on improving the state’s water quality goals as the DNR conducted its every-three-years review of water quality standards. The triennial review process ensures water quality standards, as listed in Chapter 61 of the Iowa Administrative Code, are up-to-date. Iowans had the opportunity to attend meetings held across the state.

The meetings, part of the triennial review process set forth in the federal Clean Water Act, allow Iowans the opportunity to provide the DNR information to help in setting the goals for streams and rivers. Following the meetings, the DNR met with a technical advisory committee to evaluate the suggestions. The DNR then prioritized the issues identified in the comments and developed a work plan to address those items.

See the DRAFT Triennial Review Process Summary and Work Plan report.

More information, including the full text of Chapter 61, is also available at on the left side of the screen under “Iowa Administrative Code.”

Paddling Season is Here -- Keep Safety a Priority

From the Iowa Department of Natural Resources


It’s time to get the canoes and kayaks out of storage and begin the 2011 Iowa paddling season. Before heading to the water, boats and gear stored over the winter should be examined to make sure everything is in top shape.


Safety on the water and preparing for paddling challenges mentally and physically are priorities, especially early in the season.


Even though air temperatures are warming up, water temperatures are still in the 40s and 50s, so wearing a wetsuit in case the boat dumps can protect against hypothermia. It would be a good idea to wear clothing in layers.


A lifejacket should be mandatory every time when paddling, regardless of swimming skills. State law requires children 13 years of age and younger to be wearing lifejackets.   Check lifejackets for loose or damaged straps and repair any tears. If it can’t be repaired, buy a new properly fitting lifejacket..


Remember that hypothermia can affect motor skills, energy and mental competence. A lifejacket will keep you afloat and help to re-enter the boat, swim to shore and keep the body core warm. Never paddle alone and always let someone know where you are paddling, the expected duration of the outing, and expected return.


Check boat and paddles for damage. Make sure float bags or dry bags for canoes are undamaged and have no leaks. Have all re-chargeable batteries charged and tested and make sure the GPS and weather radios are working properly.


Regardless of weather, always take a dry bag with a dry set of clothes to change into in case you get wet. Fire starting tools, a first aid kit and plenty of drinking water should always be included. If taking the cell phone, keep it in a cell phone dry sack specifically made for cell phones.


Always be aware of changing river conditions. After snowmelt and heavy spring rains, “strainers” and “sweepers” can appear in new locations. Strainers can be trees that have fallen in the river with branches above the surface that can trap you. Sweepers are low hanging trees and branches that dangle just above the surface of the water, possibly grabbing or knocking you out of the boat. And always be aware of low head dam locations. For a list of dam locations, go to


Paddling can be a physically demanding activity. Properly warming up with simple stretching exercises can help prevent injuries. Another warm up exercise is to paddle “up” river a short distance before starting the journey downstream. The resistance of the current helps with getting loose and gives the heart a nice work out.


Iowa has 18,000 miles of navigable waterways, and no shortage of streams and lakes to paddle. Paddlers can enjoy water trails that currently span 36 counties across the state via streams and lakes of all sizes and lengths. 



Groups File Suit to Vacate Antidegradation Rule


UPDATE:  Judge Joel Novak ruled on February 3 to allow the Iowa Chapter of Sierra Club, the Iowa Environmental Council and the Environmental Law & Policy Center of the Midwest to intervene in the lawsuit filed by the Iowa Farm Bureau Federation and others.  Read the judge's ruling.


The Iowa Chapter filed a Petition to Intervene in the lawsuit filed by the Iowa Farm Bureau Federation, Iowa Renewable Fuels Association and Iowa Water Environment Association.  See our news release.

Five days after the Environmental Protection Agency notified the Iowa Department of Natural Resources that it had approved the DNR's Antidegradation Rule and Implementation Procedures, three organizations filed a lawsuit asking the judge to issue a stay on the rule.  Iowa Farm Bureau Federation, Iowa Water Environment Association (formerly Iowa Water Pollution Control Association) and Iowa Renewable Fuels Association claim an illegal vote by one member of the Environmental Protection Commission (the body authorizing approval of the Iowa rule) and a conflict of interest by another member as grounds to vacate the rule

Find out about this lawsuit, the history of the antidegradation rule and more here....


Antidegradation Rule

The Environmental Protection Agency (EPA) informed  the Iowa Department of Natural Resources (DNR) that it had approved Iowa's Antidegradation Rule and Implementation Procedures in a letter on September 30.  The decision was announced to the general public in a news release on October 4, 2010.  EPA's announcement culminated a petition for rulemaking submitted to the DNR by the Sierra Club Iowa Chapter, Iowa Environmental Council and Hawkeye Fly Fishing Association in October 2007 that will bring Iowa closer to compliance of the Clean Water Act.

Also on October 4, 2010, the Iowa Farm Bureau Federation, the Iowa Water Environment Association (formerly Iowa Water Pollution Control Association) and the Iowa Renewable Fuels Association filed a lawsuit in Polk County asking a judge to vacate the rule that was three years in the making.  The lawsuit contends that the vote by the Environmental Protection Commission in December 2009 was illegal because one commissioner had moved out of state and another commissioner had a conflict of interest.  Find out about the lawsuit, the rule's history and more.

Antidegradation Rule and Outstanding Iowa Waters List Approved

The Administrative Rules Review Committee at its February meeting allowed the antidegradation rule, including the Outstanding Iowa Waters list, to pass without legislative intervention; but it wasn’t without strong opposition.

Sen. Merlin Bartz (R-Grafton) moved to object to the rule.  Bartz argued that many questions were left unanswered and that alternatives to degradation defined by the Department of Natural Resources (DNR) were not written in a manual.  The senator also argued that a provision requiring a community to determine the importance of economic or social development to justify degradation of waters “could shut down the state.”   He wanted to shift the burden of proof to the DNR if an individual or a community ever filed a lawsuit as a result of the rule. 

Sen. Wally Horn (D-Cedar Rapids) expressed concern that two quarries in his district would negatively be impacted by the rule.   He said that quarry operators are scared and he wanted assurances that the DNR won’t be “going after everybody” right away.

James Larew, General Counsel from the Governor’s Office, told legislators that a letter sent to ARRC members by Gov. Chet Culver supporting the rule was unusual, but it’s the Governor’s view that Iowans feel strongly about having clean water.  Larew said he had heard nothing during deliberations Monday to indicate that the DNR rule is capricious, unreasonable or beyond the jurisdiction of the agency, a requirement for the ARRC’s objecting to the rule.

Ultimately, legislators passed the rule by taking no action on it.   Six votes were required for Sen. Bartz’s objection motion to pass.  ARRC members voting to support Sen. Bartz’s objection included Bartz, Sen. James Seymour (R-Woodbine,) Rep. Linda Upmeyer (R-Garner) and Rep. David Heaton (R-Mt. Pleasant).  Legislators opposing the objection included Rep. Marcella Frevert (D-Emmetsburg), chair of the committee, Sen. Jack Kibbie (D-Emmetsburg), Sen. Thomas Courtney (D-Burlington), Rep. Tyler Olson (D-Cedar Rapids), Rep. Nathan Reichert (D-Muscatine) and Sen. Horn.


The Environmental Protection Commission (EPC) approved at its December 2009 meeting DNR's proposed Antidegradation Rule that includes an Outstanding Iowa Waters list in the rule package.

The OIW list was reduced to includes two lakes in Dickinson County (West Okoboji Lake and Big Spirit Lake) and 32 stream segments in northeast Iowa.

The rule now goes to the Administrative Rules Review Committee ( ARRC), a legislative oversight committee for approval before the rule is reviewed by the Attorney General's Office and approved by the Environmental Protection Agency.  The ARRC will address the rule at its February meeting.  

The purpose of the antidegradation policy is to set minimum requirements for the state to follow in order to conserve, maintain, and protect existing uses and water quality. Antidegradation procedures are designed to keep clean water clean by not allowing water quality to get worse and to prevent undue degradation of waters. If the water quality in a lake or river is better than minimum standards, increased pollutant discharges can be allowed only after a review demonstrating that increased pollution is needed to accommodate important social or economic activity.  

Key components of the rule package include:

·         No new or increased pollutants will be allowed if data shows that the increased pollution would kill or injure fish or other wildlife, or create a public health risk.

·         All waters will be protected against pollution that is not absolutely necessary to accommodate important economic or social development in the community.

·         Leave Iowa’s high-quality lakes and streams listed as Outstanding Iowa Waters (OIW) intact.  Degradation should always be prohibited.

·         Any activity that could potentially degrade water quality will be subject to an antidegradation review so that only the least polluting alternative is allowed.

The DNR accommodated polluters by reducing the number of stream segments for listing as Outstanding Iowa Waters to 32 (down from 45) and two lakes (down from seven) that were initially proposed.  The 118 miles of OIW stream segments (down from 228 miles) include several exceptional cold-water trout streams in northeast Iowa.  The two lakes included on the OIW list are Big Spirit Lake and West Okoboji Lake. Some industries and cities wanted all waters removed from the list to allow additional pollution for as long as possible.  The rule will allow more waters to be added later through a separate nomination process; however, the process will be extremely difficult and require whoever nominates the stream segment or lake to prove that the water body is worthy of protection. 



EPA Denies Mississippi River Segments' TMDL for Arsenic  


Earlier this year, EPA issued a public notice draft for total maximum daily loads (TMDL) for arsenic for two segments of the Mississippi River.  EPA intended to establish the TMDLs as milestones of a 2001 Consent Decree.  After receiving public comment and investigating, EPA determined that it is not required by the Consent Decree to establish TMDLs for the arsenic impairment.  Read the decision.




Recreational Use Assessment and Attainability


Round Three 


The Environmental Protection Commission approved a Notice of Intended Action by the Iowa Department of Natural Resources proposing rulemaking to downgrade the recreational and warm water aquatic life use designations for approximately 408 river and stream segments.  

You can find a map of the proposed designations here.  You can also find a list that includes the county where the segment is located here.  You can also search for more detailed information with DNR's database by city, facility and stream.

Round Two 

DNR requested comments from the public on their recommendations to lower recreational use protections on 119 stream segments from the current primary contact recreational standard that protects for swimming, children’s play and other full body contact recreational uses (A1 and A3) to a less protective secondary contact recreational standard that only protects for incidental contact with the water (A2).

Click here for a map that shows the streams included in the second round of stream assessments.  The map is color-coded to show the DNR recommendations.  The stream segments shown in red or blue will get the highest recreational use protection (A1 or A3).  The streams shown in green are proposed to be downgraded to the lower secondary contact level of protection (A2).   

Find the UAA streams recommended for downgrading listed by county here...

The public comment period has ended and DNR currently is reviewing comments.  A responsiveness summary will be available in the next few months with DNR's final recommendations.

If you want to look at the actual UAA assessment data and rationale for the DNR recommendations, that is available on the DNR website at  This is a searchable database where you can search by stream name or permitted facility.  If you put the stream name in you will get all the streams with that name that have UAAs.  Sometimes there is more than one stream with the same name, so you need to be sure to pick the right stream.  

Additional information is available on the DNR website at .



Round 1 


The DNR released, and in late 2007 the Environmental Protection Commission approved, action to downgrade 292 streams.  This number represented approximately one third of the anticipated re-designations.


At its April 16, 2008, meeting, the Environmental Protection Commission approved the stream use designation rules, with amendments affecting 18 stream segments.  Under the amendments, A1 primary contact recreational designation to protect swimming and canoeing was retained for 8 stream segments and A3 primary contact children's recreational use was designated for 8 stream segments.  See the list of streams included in that decision here...


In May 2009, EPA approved revised Iowa water quality standards to support recreational activities and the protection of aquatic life. The approved water quality standards protect 83 water bodies in Iowa.  In November 2009, EPA approved 79 use designation changes and disapproved 71 use designation changes from Iowa’s August 2008 submittal of revised water quality standards. In June 2010, EPA approved the Iowa DNR's designated use changes for 64 water bodies and disapproved changes for 93 water bodies. Designated uses describe the achievable recreational activities and aquatic life uses in Iowa’s waters. EPA is finalizing action on the remaining 19 water bodies.

More information on EPA’s decisions can be found in letters to DNR available at  


Ask Congress to Restore the Clean Water Act!

The Midwest's streams, rivers, lakes and wetlands are in jeopardy.  Recent Supreme Court decisions have weakened the Clean Water Act, allowing an estimated 10,000 water bodies to lose federal pollution protection.  Unless Congress acts quickly to restore the Clean Water Act, more streams, rivers, lakes and wetlands will risk unregulated pollution and outright destruction. 

In Iowa alone, more than 62% of streams and up to 72% of the state’s prairie pothole wetlands could lose CWA safeguards.

This Earth Day, do your part to protect our nation's water.  Write your members of Congress and urge them to support the Clean Water Restoration Act.  Find a sample letter here.
