EPA undermines its own proposal for more protective dust-lead hazard standards

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: July 18, 2018

Tom Neltner, J.D., is Chemicals Policy Director

On July 2, 2018, in response to a court order, the Environmental Protection Agency (EPA) published a proposed rule[1] tightening its standards for lead in dust on floors and window sills for housing and child-occupied facilities built before 1978. The agency declined to lower the standard for lead in paint – citing insufficient information – and did not consider tightening the standards for lead in soil. While the proposed rule is a tentative step forward for lead poisoning prevention, as explained below, it will create unnecessary confusion and falls far short of what the science and the law demands. Comments are due by August 16, 2018. Pursuant to an order from the Ninth Circuit Court of Appeals, EPA must finalize the rule by July 1, 2019.

FDA-approved PFAS and drinking water – Q&A on textile mills and environmental permits

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: June 21, 2018

In May 2018, we released a blog highlighting paper mills as a potentially significant source of drinking water contamination from 14 Food and Drug Administration (FDA)-approved poly- and per-fluorinated alkyl substances (PFAS) used to greaseproof paper. We showed that wastewater discharge could result in PFAS concentrations in rivers in excess of the Environmental Protection Agency (EPA)’s 70 parts per trillion (ppt) health advisory level for drinking water contamination for PFOA and PFOS, the most studied of the PFASs. We identified 269 paper mills with discharge permits that warrant investigation. Readers of the blog have asked some important questions highlighted below. As with most issues involving PFAS, there are many gaps in what we know. Based on the information provided in response to EDF’s Freedom of Information Act (FOIA) request to FDA, we hope to fill in some of the gaps and highlight key information needed to better understand the risks of PFASs.  

Question 1: Could textile mills also be a source of PFASs in drinking water?

The answer is “probably.” The FDA-approved PFASs can be used in coating paper that contacts food to repel oil, grease, and water. The same or similar FDA-approved PFASs may be used for non-food uses such as coating textiles to resist stains and repel water.

The processes used to coat paper and textiles differ in some aspects that could affect a mill’s environmental releases. For paper, the PFASs are typically added to the wet wood fibers to be made into paper. In contrast, we understand that PFASs are applied to textiles after the water is removed. Therefore, we would suspect that the amount of PFASs, whether as polymers or impurities, released with the wastewater of a textile mill would be lower compared to that of a typical paper mill. However, there is very little data available to assess the potential environmental release of PFASs from textile mills. Unlike with FDA approvals, there is no environmental review of a chemical’s use in non-food consumer products.[1] So, it would be worthwhile to investigate textile mills for use of PFASs in addition to looking at paper mills.

Using an EPA database[2], we identified 66 textile mills (PDF and EXCEL) in the US, two thirds of which are located in North and South Carolina. Based on wastewater flow, the two largest mills are both operated by Milliken. Its largest facility is in Greenville, South Carolina with a water discharge of 72 million gallons per day (MGD). The second largest is in Bacon, Georgia with a water discharge of 15 MGD. DuPont’s Old Hickory facility, near Nashville, Tennessee, had the third greatest flow at 10 MGD. We do not know whether any of the facilities use and discharge FDA-approved PFASs.

Paper mills as a significant source of PFAS contamination, but who’s watching?

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: May 21, 2018

Update: See June 21, 2018 Q&A blog on PFAS at textile mills and environmental permits

Across the country, communities are grappling with how to manage contamination of drinking water by perfluorinated alkyl substances (PFASs), a class of chemicals widely used in consumer products, industrial processes, and firefighting foams. Concern over the chemicals grew with the Environmental Protection Agency’s (EPA) 2016 release of a 70 parts per trillion (ppt) drinking water health advisory for PFOA and PFOS, two common and well-studied forms of PFASs.

One challenge to effectively evaluating the potential impacts of PFASs as well as cleaning up priority sites is that there is very little information on where these chemicals are being used. Through a Freedom of Information Act (FOIA) request to FDA, EDF obtained documents previously not made public that show that paper mills using PFASs may be a significant source of contamination to water and potentially to air and compost.

In the nearly 900 documents we received from FDA, we found environmental assessments in four Food Contact Substance Notifications (FCNs) submitted in 2009-2010 by two companies, Daikin America and Chemours.[1] FDA approved each notice, allowing the companies to sell their PFASs to make paper and paperboard repel oil and grease in food packaging such as pizza boxes, sandwich wrappers, and microwave popcorn bags. All four assessments based their estimates on what they called a “typical” paper mill that produces 825 tons of PFAS-coated paper per day and discharges 26 million gallons of water per day.[2]

  • Chemours FCN 885 estimated 95 pounds/day of its PFAS[3] in the wastewater discharge at 43,000 ppt.
  • Chemours FCN 1027 – a notification for the same PFAS – increased the amount in paper from 0.42% to 0.8% resulting in 183 pounds per day in the wastewater discharge at 83,000 ppt.
  • Daikin FCN 933 estimated 180 pounds/day of its PFAS[4] in the wastewater discharge at 83,000 ppt.
  • Daikin FCN 1044 estimated 225 pounds/day of a similar PFAS[5] in the wastewater discharge at 103,000 ppt.

EPA reaffirms Lead-Safe Renovation, Repair, and Painting Rule, citing 150% to 500% payback

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: May 10, 2018

Tom Neltner, J.D., is Chemicals Policy Director

In April 2018, the Environmental Protection Agency (EPA) completed a thorough review of its Lead-Safe Renovation, Repair, and Painting Rule (RRP) promulgated a decade ago. This rule requires contractors and landlords to use lead-safe work practices when more than minor amounts of lead-based paint in homes built before 1978 are disturbed. It also applies to pre-1978 child-occupied facilities. This review was conducted pursuant to Section 610 of the Regulatory Flexibility Act because of RRP’s significant impact on more than 300,000 small businesses that perform more than 4 million affected projects each year.

EPA concluded that RRP, including several post-2008 amendments, “should remain unchanged without any actions to amend or rescind it.” As part of the review, the agency updated its economic analysis and found that the estimated annual societal benefits, primarily in improved children’s IQ, of $1.5 to $5 billion exceeds the $1 billion in estimated annual compliance costs. Those estimates translate into an impressive annual payback of 150% to 500%. Keep in mind that these benefits do not include the lower risk of premature cardiovascular deaths attributed to adult lead exposure in a March 2018 report in Lancet.

New Study Says Lead – Even at Low Levels – is Associated with Risk of Premature Death

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: March 15, 2018

Dr. Ananya Roy is Health Scientist and Tom Neltner, J.D. is Chemicals Policy Director

This week, a team of researchers led by Dr. Bruce Lanphear published an important new study on the deadly impact of lead exposure for adults. The researchers examined data on more than 14,000 adults and found that an increase of 1 to 6.7 micrograms of lead per deciliter of blood (µg/dL) was significantly associated with an increase in mortality of 37% for all-causes, 70% for cardiovascular, and 108% for ischemic heart disease. The findings remained significant even after they considered and accounted for other factors that could have explained this effect.

This research fills a gap identified by the National Toxicology Program in 2011 in our understanding of the risk of lead exposure at low levels in adults. And it goes further by providing a quantitative relationship crucial to better evaluating the potential economic benefits of various policy options.

The study also had startling estimates about how many people are hurt by lead exposure. The authors estimated that over 400,000 Americans every year die from lead related illnesses – ten times higher than previous assessments. That’s on par with deaths from smoking cigarettes.

Federal court of appeals gives EPA one year to update lead-based paint standards

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: December 29, 2017

Tom Neltner, J.D., is Chemicals Policy Director

Update: On July 2, 2018, EPA issued the proposed rule after the court gave it a 90-day extension. The agency has one year – until July 1, 2019 – to issue a final rule. Blog clarified on timing.

This week, the federal Ninth Circuit Court of Appeals directed the Environmental Protection Agency (EPA) to update its regulations defining lead-based paint and how much lead in dust represents a hazard. The court gave EPA 90 days to issue a proposed rule and one year later to publish a final rule with an option to convince the court that it needs additional time. The court said the agency had unreasonably delayed action on a citizen’s petition submitted in 2009. The science showing the need for action has only become more compelling in the eight years since EPA acknowledged the shortcoming of its rules. Rather than drag out this litigation, the agency should move quickly to revise its lead-based paint hazard standards to better protect children’s health.

EPA set the dust-lead hazard standard in 2001 after determining that a child living in a home with those levels had only a 1 to 5% chance of having an elevated blood lead level (EBLL) as defined by the Centers for Disease Control and Prevention (CDC). The scientific evidence now shows that the risk is greater than previously estimated. In addition, CDC has tightened its definition of an EBLL. As a result, according to the American Academy of Pediatrics, the risk to a child of having an EBLL in a home that meets EPA’s current dust-lead hazard standard is more than 50%.
