Podcast: You Make Me Sick! Cocaine in the Puget Sound!?!

By / Published: March 28, 2017

After our episodes on the impact of lead on the developing brain and how microbes teeming inside us shape our health in unbelievable ways, EDF Health is proud to present the latest episode of our podcast, You Make Me Sick. On this episode, we interviewed Dr. James Meador of the National Oceanic and Atmospheric Agency about his research article where he found a soup of chemicals, including cocaine, in the waters of the Puget Sound. He explains how drugs and other chemicals of emerging concern can pass through wastewater treatment plants and end up in the surrounding waters and even the tissues of fish!

Getting the framework right for the new TSCA: EDF comments filed on key EPA proposed rules

By / Published: March 21, 2017

Environmental Defense Fund (EDF) filed extensive comments yesterday on the Environmental Protection Agency’s (EPA) proposals for the two most central “framework” rules mandated by last year’s Lautenberg Act amendments to the Toxic Substances Control Act (TSCA).

Our comments address these proposed rules:

Both sets of comments address many different provisions of the proposed rules.  EDF indicated our strong support for many aspects of the proposals, but urged changes to a number of provisions that we cannot support as proposed.  In addition, we identified provisions we believe need to be added to EPA’s rules to be consistent with or meet the requirements of the Lautenberg Act.

EDF emphasized how vital it is for EPA to meet its June 22, 2017, statutory deadline for promulgating these rules.  Because they establish processes that will require several years to begin to yield decisions on specific chemicals, delays in promulgating them in final form so that the processes can commence in the timeframe Congress intended will only serve to undermine public confidence in the new law, counter business interests to restore confidence in the chemicals marketplace, and hamper EPA’s ability to carry out its new mandates.  This is especially the case, given EPA’s appropriate recognition in both proposed rules that it will need to initiate measures as soon as possible to ensure that sufficient information will be available to inform prioritization and risk evaluation decisions.

As discussed in more detail in the comments, EDF strongly supports EPA’s decision not to codify specific scientific policies, procedures and guidance in these rules.  To do so would not be consistent with the law and would more generally represent bad policy.  EDF also agreed with EPA’s proposal not to define in its rules complex, science policy-laden terms such as “weight of the scientific evidence,” “best available science,” and “unreasonable risk.”  These concepts are best elaborated on in guidance and policy statements and best understood in the context of specific decisions on chemical substances.

Some other highlights from each set of EDF’s comments follow.   Read More »

Report: Grading the nation on lead pipe disclosure policies

By Lindsay McCormick / Published: March 14, 2017

Lindsay McCormick is a Project Manager.  

When purchasing a home, buyers expect to be informed about deficiencies, defects, or environmental hazards on the property. Since 1996, there have been federal policies to alert buyers about lead in paint. However, the likelihood that a buyer will be told their prospective home has lead pipes, including a lead service line, depends on the state in which they live.

Lead service lines (LSLs) – the lead pipes connecting water mains under the street to homes and other buildings – are the primary source of lead in drinking water. Up to 10 million homes across the nation continue to receive water through LSLs, putting millions at risk of lead exposure. Homebuyers deserve to know about this liability when they choose a home and negotiate a price. When done properly, removing the full LSL significantly reduces the risk of lead exposure.

Environmental Defense Fund (EDF) analyzed and graded the housing disclosure policies of all U.S. states and the District of Columbia according to their ability to help homebuyers make informed decisions about LSLs before they sign a sales contract by assessing state disclosure laws, required disclosure forms, and voluntary disclosure forms.  We did not address the extent to which LSLs are actively being disclosed under each policy.

Congress just fixed TSCA – yet is now gearing up to re-impose the worst flaws of the old law across the entire Federal government

By / Published: March 8, 2017

Richard Denison, Ph.D., is a Lead Senior Scientist.

I noted in a recent post EDF’s grave concerns about the Regulatory Accountability Act (RAA), which passed the House on January 11.  A shorter but still very concerning version of it may soon be introduced in the Senate, modeled on last Congress’ Senate version of RAA.  This bill would add dozens of burdensome and time-consuming hurdles to the rulemaking process, effectively crippling it and eliminating the health and safety protections rules are intended to provide.  To get a feel for all of the requirements, see this dizzying RAA flow chart.

Among other things, the RAA would mandate multiple rounds of cost and impact analysis of a potentially unlimited number of regulatory alternatives; require that all major rules go through an entirely new pre-proposal step, adding months if not longer to the rulemaking process; generally require that agencies choose the lowest-cost regulatory option, regardless of whether or not it is the best option or even sufficient to meet a law’s requirements; and require lengthy and resource-intensive public hearings on many rules.  To top all this off, the bill would require an agency to finalize a proposed rule within 2 years (subject to a 1-year extension) – a timeframe almost impossible to meet now without all of the additional requirements the Act would impose; if that deadline was not met, the agency would have to start over.

There is extreme irony in the advancement of the RAA in this Congress:  Just last June, both houses of Congress passed – with overwhelming bipartisan support – major reforms to the obsolete Toxic Substances Control Act (TSCA).  The Lautenberg Act removed from the original TSCA several major constraints on the rulemaking process that had so tied the hands of the Environmental Protection Agency (EPA) that it could not even restrict asbestos, a known carcinogen that kills more than 10,000 Americans every year.  There was widespread agreement among industry and other stakeholders that those provisions of the old TSCA were detrimental or unnecessary to an efficient regulatory system and were undermining public and market confidence in the federal chemical safety system – not to mention failing to protect public health.

So here’s the irony:  The RAA would impose those same knot-tying strictures that the Lautenberg Act just got rid of – and expand them to rulemakings undertaken by any federal agency.  Let’s look at some of these crippling requirements, based on last Congress’s Senate version of the RAA:   Read More »

EDF’s assessment of a health-based benchmark for lead in drinking water

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: February 28, 2017

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

Health professionals periodically ask me how they should advise parents who ask about what constitutes a dangerous level of lead in drinking water. They want a number similar to the one developed by the Environmental Protection Agency (EPA) for lead in dust and soil (which is the primary source of elevated blood lead levels in young children). I usually remind them that EPA’s 15 parts per billion (ppb) Lead Action Level is based on the effectiveness of treating water to reduce corrosion and the leaching of lead from plumbing; it has no relation to health. Then I tell them that EPA is working on one and to hold tight. Admittedly, that is not very satisfying to someone who must answer a parent’s questions about the results of water tests today.

On January 12, EPA released a draft report for public comment and external peer review that provides scientific models that the agency may use to develop potential health-based benchmarks for lead in drinking water. In a blog last month, I explained the various approaches and options for benchmarks that ranged from 3 to 56 ppb. In another blog, I described how EPA’s analysis provides insight into the amounts of lead in food, water, air, dust and soil to which infants and toddlers may be exposed. In this blog, I provide our assessment of numbers that health professionals could use to answer a parent’s questions. Because the numbers are only a start, I also suggest how health professionals can use the health-based benchmarks to help parents take action when water tests exceed those levels.

EDF’s read on an appropriate health-based benchmark for individual action on lead in drinking water

When it comes to children’s brain development, EDF is cautious. So we drew from the agency’s estimates calculated by its model to result in a 1% increase in the probability of a child having a blood lead level (BLL) of 3.5 micrograms of lead per deciliter of blood (µg/dL).

EDF’s assessment of a health-based benchmark for individual action on lead in drinking water
Age of child in home and type of exposure Houses built before 1950¹ Houses built 1950 to 1978² Tests show no lead in dust or soil³
Formula-fed infant 3.8 ppb 8.2 ppb 11.3 ppb
Other children 7 years or younger 5.9 ppb 12.9 ppb 27.3 ppb

Dad’s lead-laden hair dye could impact the whole family: FDA to consider barring lead compound in widely-used men’s hair dyes

By Jack Pratt / Published: February 27, 2017

Jack Pratt is Chemicals Campaign Director

Today, EDF joined a group of advocates in filing a petition that could force a ban on lead in hair dyes. Over the last several decades, we have gone to great lengths to reduce lead exposure—from eliminating the use of lead in gasoline, to tackling legacy uses in paint and water pipes. Yet, somewhat incredibly, lead is still permitted in hair dyes in the United States. Unfortunately, the evidence indicates that use can have an impact not only on the men who use it (it is seemingly exclusive to men’s dyes) but can have an impact on kids in the house too. That’s why FDA should take action and reverse their decades-old approval of lead in hair dyes.
