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

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

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

Tom Neltner, J.D.is Chemicals Policy Director

Update: One day before the Ninth Circuit Court of Appeals' March 27, 2018 deadline to issue a proposed rule, the court gave EPA a 90-day extension. The Court acted based on a March 20 request from EPA that included a detailed description of the steps the agency had taken in conducting the necessary analysis in developing the proposed rule.  Also, EPA sent to the Office of Management and Budget a proposed rule on March 26 and withdrew it three days later, presumably to continue to revise its proposal. 

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 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%.

Children’s lead exposure: Relative contributions of various sources

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

Last week, we noted in our blog that the Environmental Protection Agency (EPA) dropped the statement that paint, dust and soil are the most common sources of lead in its “Protect Your Family from Lead in Your Home” booklet. Property owners provide this booklet to prospective homebuyers and tenants in housing built before 1978. The change implicitly recognizes that there is no safe level of lead in the children’s blood, and we must reduce all sources of lead exposure. It also acknowledges that the relative contribution of air, water, food, soil, dust, and paint to children’s blood lead levels is complicated. Exposure varies significantly based on age of the home, the child’s race and age, the family’s income-level, and region of the country. Any simplification obscures these important differences.

EPA’s scientists made this clear in a model published earlier this year that pulled together the available data, divided children into three age categories, and assigned children in each category into ten groups based on their overall lead exposure. For each group, they estimated the relative contribution of air, water, food, and soil/dust (from paint). Not surprisingly, children living in older homes with lead-based paint hazards by far have the most exposure to lead. For 1 to 6 year olds in the top 90-100 percentile, more than 70% of the lead in their blood is from soil and dust. The contribution from food is 20% and drinking water is 10%. For infants, soil and dust contributes to 50% of the lead in blood, while 40% is from water and 10% from food.

Since there is no known safe level of lead in blood, we must do even more to reduce children's exposure to lead-contaminated soil and dust.

However, to prioritize action at a national level, it is important to understand how different sources contribute to lead exposure in the average child as well as the most-exposed child. We used the underlying EPA data to calculate the average relative source contribution of different sources to blood lead levels for infants from birth to six months old, for toddlers 1 to 2 years old, and young children from 1 to 6 years old. The results indicate that infants have a much higher source contribution of lead from water in comparison to older children (Figure 1). For the average child 1 to 6 years old, food is the largest source of lead exposure, with 50%, followed by soil/dust then water.

CBS News covers a chemical's tragic impact; points to urgent need to ban high-risk uses of methylene chloride

Lindsay McCormick is a Project Manager.  

This morning, CBS News focused on the tragic story of Kevin Hartley—a young man who died at the age of 21 while working with a product that contains methylene chloride. Kevin’s story, powerfully relayed by his mother Wendy, illustrates the need to ban high-risk uses of this chemical.

As we have previously noted, in January, the Environmental Protection Agency (EPA) proposed to ban methylene chloride in paint and coating removal products. The agency based its proposal on an extensive assessment of the scientific literature, which demonstrated not only lethal risks from acute exposures to methylene chloride but also a host of other acute and chronic health impacts, like harm to the central nervous system, liver toxicity, and cancer.

Products containing this chemical can be readily found in most hardware stores in America and more tragedies are all but certain, if EPA does not promptly finalize its proposed ban.

The ongoing debates in Washington over the implementation of a new chemical safety law passed just last year are often dense and dry. In sharing her son Kevin’s story, Wendy Hartley reminds us that how these policies are applied has a very real human impact. That is why EDF continues to demand EPA better protect American families from toxic chemicals like the one highlighted by CBS News today.

Federal government updates real estate disclosure booklet to address lead in drinking water

Tom Neltner, J.D.is Chemicals Policy Director

In June 2017, the federal government updated the “Protect Your Family from Lead in Your Home” booklet to expand the information provided on lead in drinking water from a few lines to a full page. Since 1996, when someone rents or buys a home built before 1978, the property owner or landlord is required to provide them with a copy of this booklet. The last update to the booklet was made in 2012.

What is removed?

  • Statement that paint, dust and soil are the most common sources of lead. The new version does not make the comparison. See our September 2017 blog for the Environmental Protection Agency’s (EPA) latest estimates on sources of lead exposure.
  • Running water for 15 to 30 seconds before drinking. The new version is silent on length of time to flush water and instead highlights taking a shower, doing laundry, or doing a load of dishes as options to flush the line at the tap. The change was necessary because homes with lead service lines, the lead pipe that connects the main under the street to the home, often experience higher levels of lead after 30 seconds of flushing.

What background is added?

  • Lead pipes, faucets and fixtures are the most common sources of lead in drinking water.
  • Reminder that older homes with private wells can have lead plumbing materials too.
  • Some states or utilities offer programs that pay for water testing for residents.

What are the new recommendations?

  • Regularly clean your faucet screen (also known as an aerator).
  • If using a filter to remove lead, follow directions to learn when to change the cartridge.
  • Use only cold water to make baby formula.
  • Contact your water company to determine if your home has a lead service line and to learn about lead levels in the system’s drinking water and water testing for residents.
  • Call EPA’s Safe Drinking Water Hotline at 1-800-426-4791 for information about lead in drinking water and 1-800 424-LEAD for other questions about lead poisoning prevention.
