A petition to make it more difficult to build animal feeding operations in the state of Iowa was shot down this week by the Iowa Environmental Protection Commission.

At present, applicants seeking to construct livestock facilities must meet only 50 percent of the state’s master matrix of rules and regulations pertaining to the structures. The petition, filed by two environmental groups, Iowa Citizens for Community Improvement and Food & Water Watch, requested that applicants meet at least 86 percent of the matrix’s requirements.

The groups argued that more strict regulation would protect residents living nearby livestock facilities from water pollution and odor. Iowa Department of Natural Resources sided with the Iowa Environmental Protection Commission and recommended against passing the petition. Noah Poppelreiter, an attorney with Iowa DNR, said that the request “goes too far” and would likely be overturned in the court system to the Des Moines Register.

The current animal feeding operation master matrix was developed fifteen years ago by state lawmakers.

Tarah Heinzen, an attorney for Iowa Food & Water Watch, said to the Register, “This vote against strengthening the master matrix is a vote for increasing Big Ag’s profits at the expense of Iowans’ health and environment.” 1,500 Iowans wrote in expressing their support for the petition.

Proponents of the petition pointed out that just two percent of applicants are denied permission to construct livestock feeding operations, which often result in poor water quality in nearby waterways. Last year, 810 water quality impairments in 610 bodies of water were reported in Iowa.

After turning down the petition, Iowa Environmental Protection Commissioner Joe Riding suggested its authors write letters to Gov. Kim Reynolds and legislative leaders asking them to change the matrix.

This week’s On The Radio segment discusses how humidity has increased significantly during all seasons in all parts of Iowa since 1971.

Transcript: Humidity in the state of Iowa has increased significantly since 1971, according to the 2017 Iowa Climate Statement released last month.

This is the Iowa Environmental Focus.

Absolute humidity, usually measured by dew point temperature, has increased significantly in all parts of Iowa during all seasons. The largest increase was found in Dubuque with a 23 percent increase in springtime humidity from 1971 to 2017.

The statement’s lead co-authors Gene Takle, director of Iowa State’s Climate Science Program and professor of geological & atmospheric sciences at ISU, and Betsy Stone, associate professor of chemical and biochemical engineering at the University of Iowa, warned that increasing humidity makes conditions more favorable for increased rainfall, extreme rain events, mold and mosquitoes.

High humidity also presents health concerns for Iowans. More humid air along with rising temperatures can make conditions dangerous for manual laborers and individuals sensitive to heat exhaustion and heat stroke.

Titled, It’s Not Just the Heat, It’s the Humidity!, the statement ends with a call for Iowans to do more to mitigate the effects of climate change through improving energy efficiency, cutting emissions and advancing renewable energies.

Water quality has been a growing concern for many Iowans in recent years, primarily due to nitrate runoff from agricultural fields frequently exceeding the EPA’s safe drinking water limits. A safe drinking water symposium will be held next Thursday and Friday, September 21 and 22 in Des Moines to unpack this issue and many others.

Challenges to Providing Safe Drinking Water in the Midwest” will feature Iowa-based and nationally-recognized speakers and discussion panels related to local, regional and national water quality issues. A few of the topics to be discussed are the Health Impacts of Nitrate in Drinking Water, Drinking Water Treatment Concerns, New and Emerging Drinking Water Threats, and Communicating with the Public on Drinking Water Issues.

The one-and-a-half-day event is co-sponsored by several centers at the University of Iowa, Drake University, the University of Northern Iowa as well as the Iowa Association of Water Agencies, and the Central Iowa Drinking Water Commission.

The event, which will be held at the Drake University Shivers Facility, is open to the public. Additional information regarding agenda, registration, hotel, and parking is available at https://cph.uiowa.edu/ehsrc/drinking-water-symposium-2017.html.  Alternatively, call (319) 335-4756 to speak with an organizer.

What: Challenges to Providing Safe Drinking Water in the Midwest: A Symposium

When: September 21 from 8 am to 5 pm, September 22 from 8 am to 12 pm

Where: Drake University, Shivers Facility, Des Moines

On The Radio – Storms like Harvey more likely due to changing climate

This week’s On The Radio segment discusses how climate change is making storms like Harvey more likely.

Transcript: Over 51 inches of rain fell in the Houston area last month during Hurricane Harvey, setting a record for the continental U.S., and scientists say a changing climate added to the deluge.

This is the Iowa Environmental Focus.

The Clausius-Clapeyron equation, a law of thermodynamics, says that the warmer a body of air is, the more moisture it can hold. Sea surface temperatures near where Harvey picked up its strength were about 1 degree Celsius higher than average, making the air above it warmer too. In this case, the atmosphere surrounding Hurricane Harvey was able to hold roughly three to five percent more moisture than usual.

In addition, sea levels have risen by about six inches in the last few decades due to global warming. Even minimal sea level rise can lead to a large increase in damages to structures on land during a flood.

While climate change did not cause Hurricane Harvey directly, scientists say it will likely make category four storms like it more frequent in the future.

Iowa DNR fails to obey some state regulations

A state audit released on Tuesday revealed that the Iowa Department of Natural Resources has failed to follow state law related to identifying and safeguarding wetlands, monitoring public works projects on the local level and establishing a clean air advisory panel.

In its defense, Iowa DNR claims that state law pertaining to these issues are often duplicative or less stringent than federal requirements, according to a report from the Des Moines Register. Federal requirements for wetland protection specifically exceed regulation put forth by the state, Iowa DNR director Chuck Gipp told the Register. He said, “We recognize and understand the value of wetlands.” The Iowa law “is asking us to do something that would be even less stringent than the federal code.”

In response, Iowa Environmental Council’s water program coordinator Susan Heathcote noted that federal oversight related to water quality is questionable at present, considering that President Trump is expected to repeal and revise an Obama era water quality regulation soon.

More specifically, the audit found that the Iowa DNR has not established a program aimed at assisting in the development of wetlands around closed agricultural drainage areas, which would aid in the filtration of nutrient rich water flowing into municipal taps. The news that the state is failing to abide by existing water quality-related regulations comes after another legislative session during which state legislators failed to provide funding for more robust water quality measures Iowa voters approved more than seven years ago.

Lessons for Iowans in the wake of Harvey

As some of the floodwater finally recedes from the Houston area following Hurricane Harvey,  Hurricane Irma, a category five storm, threatens to devastate the Florida Keys this weekend.

Climate change increased the amount of rainfall that fell on Houston during the recent storm, according to a statement from Clare Nullis Kapp, media officer for the World Meteorological Organization. Karen Tigges, a Des Moines resident and operations analyst at Wells Fargo, said in a recent Des Moines Register Letter to the Editor that Harvey has something to teach the people of Iowa. The letter reads:

“Houston: A tragic example of a city caught at the mercy of worsening storms and increased rainfall. Flooding is nothing new to Houston, but it appears that this time they are really paying the price for unwise growth.

Unfortunately, flooding is not unfamiliar to the city of Des Moines either. We are growing in the metro as well. We must take the warnings of storm events seriously. It’s said that the lack of zoning ordinances in Houston led to the loss of wetlands and grasslands that could have absorbed at least some of the onslaught of water. How does that compare with planning for growth here in the metro area? Is the growth of our urban areas leading to higher risks of flooding due to more impermeable surfaces in the form of more paved roads and rooftops?

As the city prepares for a future that will likely include more intense rainfall events, thanks to a warmer, more humid climate, we citizens need to take an active role in seeing that effective planning and policies are put in place to make Des Moines ready to face this unpleasant reality.

We can do that by weighing in on the city’s new planning and zoning code. We also need to do that by electing and supporting leaders that will be proactive in setting the course of the metro area on a path of resilience and preparedness for what storms of the future may bring.”

Wildfires bring smoke to Iowa

A yellowish haze blanketed most of eastern Iowa this Labor Day weekend thanks to wildfires in the western U.S. and Canada.

Wildfires throughout Montana, Manitoba and Saskatchewan are credited with much of this weekend’s smoke. Just this Sunday, evacuations were ordered for Glacier National Park in Montana and 140 campers were rescued from a smoldering forest on Sunday in Oregon.

As the climate changes, wet areas become wetter and dry areas become drier, allowing for longer wildfire seasons in many parts of the western U.S. According to the Union of Concerned Scientists, compared to the 1980’s, wildfires now last nearly five times as long, occur almost four times as often and burn more than six times the land area on average.

National Weather Service meteorologist Dave Cousins said that this weekend’s haze cut visibility at Davenport Municipal Airport by two and a half miles.

A report out of Dubuque revealed that the Air Quality Index (AQI) in the area is moderate to unhealthy for individuals sensitive to poor area quality.
