Dakota Access Pipeline to double its oil under Iowa

Oil flowing under Iowa through the controversial Dakota Access Pipeline will soon double, as permitted by the Iowa Utilities Board Friday.

Where there were previously 550,000 barrels of oil daily, there will be 1.1 million barrels,  according to the Des Moines Register.  The Register reported that the state determined risk of increased spill probability or volume to be low.

The Dakota Access Pipeline, which carries oil from the Dakotas to Illinois, was heavily protested in 2016 and 2017 by the Standing Rock Sioux and allies. Critics feared that the pipeline, which passes under the Missouri River, would contaminate water supplies on the Standing Rock Reservation.

The Iowa Utilities Board order occurred two days after a federal judge on Wednesday ordered a major environmental review of the Dakota Access Pipeline to more thoroughly assess risk of environmental contamination.

This week’s episode of EnvIowa features a discussion with CGRER co-director Dr. Jerry Schnoor. He is, among other things, a professor of civil and environmental engineering with a long career studying climate change, water quality and environmental toxicology. Listen to hear Schnoor discuss the urgency of climate change, his efforts to clean up chemical pollution using plants and why he wants our youth to get angry.

AP story showcases tension in Iowa over factory farming

A news story published last week featured an Iowa farmer who illegally built to un-permitted barns containing about 2,400 hogs. State officials were unaware of the concentrated animal feeding operations (CAFOs) for years. 

That farmer and others are fighting in what Associated Press correspondent John Flesher called a “battleground” in Iowa. Questions of pollution and regulation have inspired lawsuits, anti-CAFO alliances and neighborly tensions throughout the state, as animal feeding operations continue to proliferate.

Below are four key takeaways from Flesher’s in-depth report. Read the full-length story on apnews.com.

  1. The federal government relies state data for animal feeding operation data. In many cases, states keep tabs on only the largest operations (in Iowa, a true “CAFO” has a minimum of 1,000 species-variable “animal units” per confinement). The EPA counted about 20,300 CAFOs nationwide in 2018.  The U.S. Department of Agriculture estimates there are about 450,000 animal feeding operations–places animals are raised in confinement (of any size)– nationwide.
  2. The Iowa Department of Natural Resources discovered thousands of previously undocumented animal feeding operations in 2017.  Some point to this case as proof of under-regulation, but state regulators said the discoveries indicated a well-functioning system.
  3. Under the 1972 Clean Water Act, especially large livestock operations need permits for discharging waste into waterways. Since such discharges are often unintended, however, state and federal environmental agencies can only mandate permits for operations caught discharging waste. In some cases, farmers have been able to make spill-proofing improvements instead of applying for permits.
  4. Studies show that livestock operations and anaerobically decomposing waste release massive amounts of ammonia and greenhouse gases. Because such emissions are difficult to measure, though, they are unregulated by the Clear Air Act. Studies have additionally correlated these emissions to human health issues such as childhood asthma. Cause/effect is impossible to prove, however.

CGRER’s Co-director Jerry Schnoor sat down with Iowa Public Radio to discuss what life with climate action would like and how Iowans can adapt their own lives with impending climate changes. We have already seen severe flooding and intense preciptations, but what’s next?  You can listen to learn more here.

EnvIowa Podcast Revived: Talking human/environment systems with Silvia Secchi

Julia Poska| February 3, 2019

The UI Center for Global and Regional Environmental Research is excited to announce the revival and reimagination of our EnvIowa podcast. This weekly podcast will feature 10- to 20-minute interviews with Iowa environmental experts, mainly our own member scientists.

While these researchers are certainly well versed in the complicated jargon of their disciplines, our interviews aim to make their ideas accessible to a general audience. Questions focus not only on the research itself, but how the experts believe it can be applied to solve environmental challenges.

Today’s installment features an interview recorded January 28 with Dr. Silvia Secchi, an interdisciplinary economist and geographer at the University of Iowa. Listen to learn more about Dr. Secchi’s fascinating research on human/environmental interactions in the Mississippi River watershed and how agriculture in particular plays a role within the larger system.

UI research links pesticide and cardiovascular death

Pyrethroids are commonly found in most household insecticides (via flickr).

New observational research has found that people with high exposure to common “pyrethroid” insencticides were 56% more likely to die during a study period than others. Cardiovascular disease was the leading cause of death in the exposed.

CGRER member Wei Bao, assistant professor of epidemiology in the University of Iowa College of Public Health, is an author of the study, published Jan. 30 in JAMA Internal Medicine.

Pyrethroid insecticides are used in most household insecticides and some pet products and head-lice shampoos. The study followed a sample of 2,116 adults who took the United States National Health and Nutrition Examination Survey between 1999 and 2002, representative of the U.S. population as a whole. The researchers noted levels of pyrethroid-associated chemicals in their urine and found death records to determine how many had died by 2015, as well as their cause of death.

While those with higher pyrethroid exposure were more likely to die overall, the highly exposed were three times more likely to suffer cardiovascular deaths than others as well.  Bao said in an Iowa Now feature that the study does not prove that the insecticides are the cause of death, only that death and exposure are correlated.
