EPA Delays Action on Toxic Nonstick Chemicals, Sets No Limit
The U.S. Environmental Protection Agency (EPA) will propose a regulatory determination on highly toxic nonstick chemicals "by the end of this year," a timeline that's been criticized as too slow to take on the notorious drinking water contaminants.
At a press conference on Thursday in Philadelphia, EPA acting administrator Andrew Wheeler announced a "comprehensive cross-agency plan" to tackle perfluoroalkyl and polyfluoroalkyl compounds, or PFAS, while keeping the federal health advisory level at 70 parts per trillion.
"We feel right now that 70 parts per trillion is a safe level for drinking water," Wheeler said, as quoted by the Foster's Daily Democrat, referring to PFOS and PFOA—two common PFAS compounds.
But health and environmental groups, as well as the Center for Disease Control and Prevention (CDC), have advised far lower levels than what the EPA considers safe. The CDC said in its toxicology report published in June that the risk level for PFOA should be 11 parts per trillion and just over 7 parts per trillion for PFOS.
The man-made chemicals are found in a wide range of products, from non-stick cookware to firefighting foam. The compounds have been found in military bases and in many species of wildlife around the world. A Harvard 2016 study found that 6 million Americans get drinking water from sources that exceed current EPA guidelines for the chemicals.
Exposure has been linked to health issues such as cancer, liver disease, fertility problems, thyroid issues and asthma. Even extremely low, daily doses of the substances showed an adverse impact on lab animals.

Responding to today's announcement, the Natural Resources Defense Council (NRDC) said in an emailed press release that the EPA is failing to take strong, decisive action to protect the public from PFAS.
"While the agency fumbles with this 'mis-management plan,' millions of people will be exposed to highly toxic PFAS from drinking contaminated water," said Erik Olson, senior director for health and food at the NRDC, in a statement. "As a guardian of public health, Administrator Andrew Wheeler should revisit this embarrassing decision. With EPA asleep at the wheel, it's up to states, citizens, and public-minded companies to take action."
Further, as noted by The Hill, rather than setting a drinking water standard, the EPA announced today it will issue a draft regulation by the end of 2019, which kickstarts months to years of long public comment periods.
In a press release, Sen. Tom Carper (D-Del.), top Democrat on the Senate Environment and Public Works Committee, criticized Wheeler for effectively prolonging the need for a drinking water standard for PFOA and PFOS by almost a year.

Carper pointed out that in May 2018, then-EPA Administrator Scott Pruitt already announced four "concrete steps" to address PFAS contamination and to take steps to set a maximum contaminant level.
"Nearly a year ago, then-Administrator Scott Pruitt announced that EPA would decide on whether to set a drinking water standard for PFOA and PFOS as part of its PFAS Action Plan," Carper said. "The PFAS Action Plan being trumpeted by EPA today is insufficiently protective, and it explains why Acting Administrator Andrew Wheeler would not commit to setting a drinking water standard for PFAS during his nomination hearing last month."
Carper added, "It has taken them nearly a year just to kick the can even further down the road."
He urged the acting EPA boss to "treat this public health threat with the urgency it deserves."
Regional Administrator Doug Benevento brushed aside the criticism about the EPA's timeline.
"It would be inaccurate to say we're not setting an MCL [maximum contaminant level]," he said, according to an EPA Region 8 tweet. "We are moving through the regulatory process required under the Safe Water Drinking Act before we make a determination."

The 2020 hurricane season is now expected to be the most active since at least the early 1980s, meteorologists at Colorado State University, a standard bearer for seasonal hurricane predictions, announced Wednesday.
Three years ago, scientists predicted it would happen. Now, new NASA satellite imagery confirms it's true: two ice caps in Canada's Nunavut province have disappeared completely, providing more visual evidence of the rapid warming happening near the poles, as CTV News in Canada reported.

Lebanese Prime Minister Hassan Diab says he believes Tuesday's explosion in Beirut could have been caused by large quantities of ammonium nitrate stored in the port.
What Is Ammonium Nitrate?<p>Ammonium nitrate is a white crystalline salt that can be fairly cheaply produced from ammonia and nitric acid. It is soluble and often used as fertilizer, as nitrogen is needed for healthy plant development.</p><p>Ammonium nitrate in its pure form is not dangerous. It is, however, heat sensitive. At 32.2 degrees Celsius (89.96 degrees Fahrenheit), ammonium nitrate changes its atomic structure, which in turn changes its chemical properties.</p><p>When large quantities of ammonium nitrate are stored in one place, heat is generated. If the amount is sufficiently vast, it can cause the chemical to ignite. Once a temperature of 170 C is reached, ammonium nitrate starts breaking down, emitting nitrous oxide, better known as laughing gas. Any sudden ignition causes ammonium nitrate to decompose directly into water, nitrogen and oxygen, which explains the enormous explosive power of the salt.</p>
Deadly Disasters<p>As ammonium nitrate is a highly explosive chemical, many countries strictly regulate its use. Over the past 100 years, there have been several disasters involving the chemical.</p><p>In 1921, for example, a massive blast occurred at a BASF chemical plant in Ludwigshafen in the German state of Rhineland-Palatinate. About 400 metric tons of a mixture of ammonium sulfate and ammonium nitrate exploded, killing 559 people and injuring 1,977. The plant was largely destroyed in the blast, which could be heard as far away as Munich, some 300 kilometers (186 miles) distant.</p><p>In 2015, explosions caused by ammonium nitrate ripped through the <a href="https://www.dw.com/en/china-convicts-dozens-for-last-years-giant-explosions-in-tianjin/a-36324321" target="_blank">Chinese port city of Tianjin</a>. Eight hundred metric tons of the chemical were said to have been stored along with other substances in a warehouse for hazardous materials. The blasts killed 173 people and destroyed an entire city district.</p><p>Two years earlier, in 2013, an ammonium nitrate explosion occurred at the West Fertilizer Company site in Texas, killing 14 people. And in 2001, 31 people died in Toulouse, France, in an explosion caused by the chemical.</p>
Terrorist Favorite<p>In Germany, the purchase and use of ammonium nitrate is regulated by the explosives act. This is because the cheap, highly explosive and relatively easily obtainable material has in the past been used by terrorists to carry out attacks.</p><p>For example, in 1995, U.S. conspiracy theorist and gun enthusiast Timothy McVeigh used a mixture of ammonium nitrate and other substances to bomb the Alfred P. Murrah Federal Building in Oklahoma City. Norwegian far-right extremist Anders Behring Breivik also used ammonium nitrate in a car bomb attack in Oslo in 2011.</p>

Most Americans know about the Dietary Guidelines for Americans primarily through their colorful representations: the original food pyramid, which a few years ago morphed into MyPlate. The guidelines represent the government mothering us to choose the healthiest vegetables, grains, sources of protein, and desserts, and to eat them in the healthiest portions.
As innocuous as the food pyramid and MyPlate seem, they are actually a matter of life and death.
