  • Chemical Concerns – Insights on Air Pollution, Public Health, and Chemical Safety

    Environmental Defense Fund, Earthjustice, Natural Resources Defense Council, and Safer Chemicals Healthy Families yesterday told the Environmental Protection Agency (EPA) that the 20 draft scope documents the agency released for public comment on April 9 and April 23, 2020, fail to meet TSCA and EPA regulatory requirements.  The groups called on EPA to revise the drafts to include the information that both TSCA and EPA’s Risk Evaluation Rule require be included, and then make the revised draft scopes available for public comment.  (more…)

    The Trump administration’s disregard for science has been clear in the response to the COVID-19 pandemic, but it’s not the only health threat they’re making worse by ignoring overwhelming scientific evidence. For three years the administration has systematically sought to weaken clean air safeguards, endangering all Americans.

    We know air pollution causes heart disease, diabetes and lung disease—and that the people suffering from these conditions are at greater risk of severe illness from COVID-19. Independent of the ongoing pandemic, air pollution is responsible for tens of thousands of deaths across America year after year. This underscores the vital importance of pollution protections to protect human health both during and after the COVID-19 crisis.

    Unfortunately, EPA Administrator Andrew Wheeler has proposed to retain an outdated and inadequate standard for fine particulate matter (PM2.5) pollution despite strong scientific evidence that it must be strengthened to adequately protect human health.

    To understand what having this pollution standard means for families living in the Greater Houston area, Harvard University and EDF scientists undertook an analysis of the impacts of PM2.5 exposure across the city. We found that:

    By ignoring the scientific evidence and retaining the current standard, Administrator Wheeler is ignoring the very real health impacts felt by Houstonians and communities across the country from exposure to fine particle pollution.

    Yesterday, in the midst of the COVID-19 national emergency, the Environmental Protection Agency (EPA) closed the comment period on an extremely flawed draft risk evaluation on the toxic chemical, trichloroethylene (TCE).

    Due to the many scientific and legal concerns raised by the draft risk evaluation, and its significance for any future regulation of TCE, the draft needs thorough and careful review from experts, the public, and other affected stakeholders. However, EPA refused to delay the deadline for the draft risk evaluation’s comment period, despite the growing hardships and major disruptions resulting from the current COVID-19 crisis.  EPA now seems intent on racing to the finish line with its flawed evaluation, ignoring multiple requests to ensure the document is fully vetted:

    Note to readers: As we all grapple with the grave global health challenge from COVID-19, we want to acknowledge the essential service that the public health professionals at water utilities provide in delivering safe water not only for drinking but for washing our hands and our surroundings. In the meantime, we are continuing to work towards improved health and environmental protections – including reducing lead in drinking water. We’ll plan to keep sharing developments regarding lead in drinking water that may be useful to you. In the meantime, please stay safe and healthy.

    Lead service line (LSL) inventories provide useful insights into the location and number of LSLs in states and the funding needed to fully replace these lines. In previous blogs, we examined mandatory reporting by utilities of service line material in Illinois and Wisconsin.[1] Here, we examined a March 2020 preliminary report by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) summarizing data submitted by 1,029 utilities. Unlike the annual reporting in Illinois and Wisconsin, Michigan required utilities to submit a preliminary inventory by January 1, 2020 and requires a complete inventory before 2025. While the preliminary report allows lines to be designated as unknown, the material must be determined by 2025. This is a two-step process, rather than the annual report approach that California has taken.

    Michigan reports less than 100,000 LSLs and 276,000 lines of unknown material that may be lead

    The state’s preliminary report is based on 1,029 utilities[2] (74% of the state’s 1,386 total) with 2.40 million service lines (90% of the 2.66 million total).[3] This reporting rate is lower than what Illinois experienced at a similar stage in the first year of mandatory reporting.

    For the 1,029 utilities that reported, utilities reported 99,000 (4% of total) lead, 21,000 (0.9%) galvanized steel,[4] 177,000 (7%) of unknown material but likely to be lead, and 276,000 (12%) as unknown with no information. If all of the four categories are actually lead (which is unlikely), there would be 573,000 (23%) LSLs in Michigan.

    It was only in February that Reveal News’ Elizabeth Shogren exposed the Trump White House’s role in dramatically weakening the Environmental Protection Agency’s (EPA) draft risk evaluation for the solvent trichloroethylene (TCE), which is linked to fetal heart defects at low doses.  The White House’s 11th-hour intervention, led by former chemical industry official Dr. Nancy Beck, forced EPA to rely on a different health effect that would allow 500 times greater exposures to the ubiquitous toxic chemical.

    There was every reason to expect this episode was not a one-off, given Beck’s other actions both while at EPA and once arriving at the White House.  Sure enough, last week Ellen Knickmeyer of the Associated Press exposed another such incident, this time involving a group of chemicals collectively known as “perfluoroalkyl and polyfluoroalkyl substances” or PFAS that are showing up as environmental contaminants all over the country.[pullquote]Beck’s first order of business was to compel her former colleagues at EPA to submit the proposed PFAS rule for White House review, which neither the Obama administration nor the Trump administration up to that point had deemed necessary.[/pullquote]

    Knickmeyer reported on documents obtained by Senator Tom Carper of Delaware, ranking member of the Senate’s Environment and Public Works Committee, that detail Beck’s largely successful effort to scale back a rule EPA first proposed in 2015.  Called a Significant New Use Rule, or SNUR, it would require companies seeking to import products containing certain PFAS to notify EPA in advance, thereby allowing EPA to determine whether to allow the import and impose needed restrictions.  Sen. Carper made the documents public via a letter he sent to EPA Administrator Andrew Wheeler calling on EPA to finalize the original rule instead of the watered-down re-proposed rule EPA released for public comment in February.  (more…)

    Note to readers: As we all grapple with the grave global health challenge from COVID-19, we want to acknowledge the essential service that the public health professionals at water utilities provide in delivering safe water not only for drinking but for washing our hands and our surroundings.

    During the past few weeks, Congress has taken extraordinary measures to provide much-needed emergency relief to people as we collectively struggle with the COVID-19 crises. Over the coming months, lawmakers have said they will turn their attention to providing funding to stimulate the economy with a focus on water infrastructure as a priority. Lead pipe replacement should be an essential part of that effort.

    To guide the Congressional effort, EDF and hundreds of others signed onto U.S. Water Alliance’s COVID-19 Relief and Recovery: Guiding Principles to Secure Our Water Future. The four principles are:

    1. Ensure water is reliable and affordable to all
    2. Strengthen water utilities of all sizes
    3. Close the water access gap
    4. Fuel economic recovery by investing in water systems

    In line with of our support for these principles, EDF is advocating that Congress provide $45 billion for water utilities to fully replace lead service lines (LSL) – the lead pipes connecting a home to the water main under the street. Today, there are more than nine million homes still serviced by LSLs in the country, exposing millions of children and adults to the myriad of harms associated with lead. For children, these harms include undermining brain development. In adults, lead has been shown to cause heart disease, cancer, and impact the neurological, reproductive, and immune systems. While there is broad consensus that LSLs must be fully removed to protect public health, funding challenges have stymied progress.
