EPA Finalizes First-of-its-Kind Strategy to Protect 900 Endangered Species from Herbicides

WASHINGTON – Today, Aug. 20, the U.S. Environmental Protection Agency released its final Herbicide Strategy, an unprecedented step in protecting over 900 federally endangered and threatened (listed) species from the potential impacts of herbicide, which are chemicals used to control weeds. EPA will use the strategy to identify measures to reduce the amount of herbicides exposure to these species when it registers new herbicides and when it reevaluates registered herbicides under a process called registration review. The final strategy incorporates a wide range of stakeholder input, ensuring EPA not only protects species but also preserves a wide range of pesticides for farmers and growers.

“Finalizing our first major strategy for endangered species is a historic step in EPA meeting its Endangered Species Act obligations,” said Deputy Assistant Administrator for Pesticide Programs for the Office of Chemical Safety and Pollution Prevention Jake Li. “By identifying protections earlier in the pesticide review process, we are far more efficiently protecting listed species from the millions of pounds of herbicides applied each year and reducing burdensome uncertainty for the farmers that use them.”

The Biden-Harris Administration’s new approaches for protecting endangered species, which include the Herbicide Strategy, have resolved multiple lawsuits against EPA. For decades, EPA has tried to comply with the Endangered Species Act (ESA) on a pesticide-by-pesticide, species-by-species basis. However, because this approach is very slow and costly, it resulted in litigation against the agency and uncertainty for users about the continued availability of many pesticides. At the beginning of 2021, EPA faced almost two dozen lawsuits covering thousands of pesticide products due to its longstanding failure to meet ESA obligations for pesticides. Some of these lawsuits resulted in courts removing pesticides from the market until EPA ensured the pesticides comply with the ESA. Now, all but one of those lawsuits has been resolved. Unlike EPA’s historic approach to compliance, the Herbicide Strategy identifies protections for hundreds of listed species up front and will apply to thousands of pesticide products as they go through registration or registration review, thus allowing EPA to protect listed species much faster.

In July 2023, EPA released a draft of this strategy for public comment. EPA received extensive comments, with many reiterating the importance of protecting listed species from herbicides but also minimizing impacts on farmers and other pesticide users. In response to comments, EPA made many improvements to the draft, with the primary changes falling into three categories:

  • Making the strategy easier to understand and incorporating up-to-date data and refined analyses;
  • Increasing flexibility for pesticide users to implement mitigation measures in the strategy; and,
  • Reducing the amount of additional mitigation that may be needed when users either have already adopted accepted practices to reduce pesticide runoff or apply herbicides in an area where runoff potential is lower.

EPA focused this strategy on conventional herbicides used in agriculture in the lower 48 states because the most herbicides are applied there. In 2022, approximately 264 million acres of cropland were treated with herbicides, according to the Census of Agriculture from the U.S. Department of Agriculture (USDA). The number of cropland acres treated with herbicides has remained fairly consistent since the early 2010s. EPA is also focusing this strategy on species listed by the U.S. Fish and Wildlife Service (FWS) because herbicides generally impact those species. For species listed by the National Marine Fisheries Service, EPA is addressing pesticide impacts through a separate initiative with that agency.

Final Herbicide Strategy

The final strategy includes more options for mitigation measures compared to the draft, while still protecting listed species. The strategy also reduces the level of mitigation needed for applicators who have already implemented measures identified in the strategy to reduce pesticide movement from treated fields into habitats through pesticide spray drift and runoff from a field. The measures include cover crops, conservation tillage, windbreaks, and adjuvants. Further, some measures, such as berms, are enough to fully address runoff concerns. Growers who already use those measures will not need any other runoff measures. EPA identified these options for growers through its collaborations with USDA under its February 2024 interagency MOU and through over two dozen meetings and workshops with agricultural groups in 2024 alone. 

The final strategy also recognizes that applicators who work with a runoff/erosion specialist or participate in a conservation program are more likely to effectively implement mitigation measures. These conservation programs include the USDA’s Natural Resources Conservation Service practices and state or private stewardship measures that are effective at reducing pesticide runoff. The strategy reduces the level of mitigation needed for applicators who employ a specialist or participate in a program. Geographic characteristics may also reduce the level of mitigation needed, such as farming in an area with flat lands, or with minimal rain such as western U.S. counties that are in the driest climates. As a result, in many of those counties, a grower may need to undertake few or no additional runoff mitigations for herbicides that are not very toxic to listed species. 

The final strategy uses the most updated information and processes to determine whether an herbicide will impact a listed species and identify protections to address any impacts. To determine impacts, the strategy considers where a species lives, what it needs to survive (for example for food or pollinators), where the pesticide will end up in the environment, and what kind of impacts the pesticide might have if it reaches the species. These refinements allow EPA to focus restrictions only in situations where they are needed.

The final strategy will also expedite how EPA complies with the ESA through future consultations with FWS by identifying mitigations to address the potential impacts of each herbicide on listed species even before the agency completes the consultation process for that herbicide—which in many cases, can take five years or more. Further, EPA and FWS expect to formalize their understanding of how this strategy can inform and streamline future ESA consultations for herbicides.

The final strategy itself does not impose any requirements or restrictions on pesticide use. Rather, EPA will use the strategy to inform mitigations for new active ingredient registrations and registration review of conventional herbicides. 


EPA understands that the spray drift and runoff mitigation from the strategy can be complicated for some pesticide users to adopt for the first time. EPA has also developed a document that details multiple real-world examples of how a pesticide applicator could adopt the mitigation from this strategy when those measures appear on pesticide labels. To help applicators consider their mitigation options, EPA is developing a mitigation menu website that the agency will release in fall 2024 and plans to periodically update with additional mitigation options, allowing applicators to use the most up-to-date mitigations without requiring pesticide product labels to be amended each time new measures become available. EPA is also developing a calculator that applicators can use to help determine what further mitigation measures, if any, they may need to take in light of mitigations they may already have in place. EPA will also continue to develop educational and outreach materials to inform the public and help applicators understand mitigation needs and where descriptions of mitigations are located.

The Final Herbicide Strategy and accompanying support documents are available in docket EPA-HQ-OPP-2023-0365 at the Regulations.gov page.

Moms Fight to Clean Up Thousands of Tons of Nuclear Waste in St. Louis (Exclusive)

Moms Fight to Clean Up Thousands of Tons of Nuclear Waste in St. Louis (Exclusive)

The first warning sign was the stench that seemed to fill the air of Dawn Chapman’s suburban St. Louis neighborhood in 2012.

“You could smell burning, but there was something different about it, like jet fuel,” she says in this week's issue of PEOPLE. Her three children started to wake in the night with irritated eyes or bloody noses caused, she believes, by the caustic fumes.

By January 2013 Chapman, then a full-time mom, had discovered the source of the overpowering odor: a fire in an underground quarry at the Bridgeton Landfill about two miles from her home.

The blaze raised fresh alarm about a decades-old issue — how much atomic waste had been stored in the region post-World War II, with some radioactive material mixing with a local creek and, separately, 43,000-plus tons of it piling up at West Lake Landfill, which is next to Bridgeton Landfill.

For more on Dawn Chapman and Karen Nickel's fight to clean up nuclear waste in their St. Louis suburb, pick up this week's issue of PEOPLE, on newsstands Friday, or subscribe.

Their suburban dream was tainted by toxic remnants of the country’s wartime past. After the bombing of Pearl Harbor in 1941, the U.S. chose St. Louis as one of the places to process the uranium used in the nation’s atomic weapons program the Manhattan Project.

In the decades that followed, the resulting radioactive waste was dumped close to the city airport, and contaminants washed into nearby Coldwater. In the ’70s the waste was moved to the West Lake Landfill, amid single-family homes in Bridgeton. In 1990 the landfill was designated a Superfund site — one of the nation’s most contaminated areas.

Many residents were none the wiser. Nickel grew up in the ’60s and ’70s playing softball in the parks beside Coldwater, where years later scientists would discover Manhattan Project-era radioactive material in the soil.

“Fifteen people on my street passed from rare cancer in their 40s and 50s,” she says.

Three of her four adult children, whom she raised with husband Todd in a house less than two miles from the landfill, live with neurodevelopmental challenges, she says. And Nickel has lupus, an autoimmune disease she blames on exposure to radioactivity.

Chapman and her husband, Brian, moved to the Bridgeton area in 2000, unaware of the history. In 2002 her husband learned he had Crohn’s disease.

Pollution is a problem that affects everyone, no matter where they live. Even if you reside in a rural area, you are still subject to many types of pollution, both outdoors and inside your home.
Today we will look at several air quality sensors that you can use with a microcontroller. We’ll test them out using both an ESP323 and an Arduino, and we’ll also compare the readings to a commercial air quality meter to see if there is any correlation between readings.


We’ll be taking a look at the following sensors:

- MQ Gas Sensors (various models).
- PMS5003 PM2.5 Particulate Matter Sensor.
- BME280 Temperature, Humidity & Air Pressure Sensor.
- BME680 Temperature, Humidity & Gas Sensor.
- AHT20 Precision Temperature & Humidity Sensor.
- CCS811 Air Quality Sensor.
- SGP30 Air Quality Sensor.
- SGP40 Air Quality Sensor.

We’ll see how they work and what parameters they can measure, and we’ll hook them up and run a demo.

Then we’ll put a bunch of sensors together on an ESP32 to make an environmental monitoring platform.

EPA Takes Important Step to Advance PFAS Strategic Roadmap, Requests Public Input and Data to Inform Potential Future Regulations under CERCLA

 

EPA Takes Important Step to Advance PFAS Strategic Roadmap, Requests Public Input and Data to Inform Potential Future Regulations under CERCLA

WASHINGTON (April 13, 2023) — Today, the U.S. Environmental Protection Agency (EPA) is issuing an Advance Notice of Proposed Rulemaking (ANPRM) asking the public for input regarding potential future hazardous substance designations of per- and polyfluoroalkyl substances (PFAS) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as “Superfund.”

“Today’s announcement highlights EPA’s commitment to transparency and the use of the best available science to tackle PFAS pollution and protect people from exposure to these forever chemicals,” saidBarry N. Breen, Acting Assistant Administrator forEPA’s Office of Land and Emergency Management. “This is a key commitment under the Agency’s PFAS Strategic Roadmap and will provide an opportunity for a large and diverse group of stakeholders, including the public, state and local governments, Tribes, industry, businesses, environmental groups, and universities, to provide input and help EPA gather the latest science and information regarding PFAS.”

This request for input and information follows EPA’s September 2022 proposed rule to designate two PFAS — perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), and their salts and structural isomers — as hazardous substances under CERCLA. EPA is currently reviewing comments received on this proposed rule.

Through this ANPRM, EPA is seeking input on whether to propose to designate additional PFAS, including HFPO-DA, sometimes called GenX, and compounds that degrade in the environment by processes such as biodegradation, photolysis, and hydrolysis, to form certain PFAS. EPA is also seeking information on whether some PFAS compounds can or should be designated as a group or category.

PFAS can accumulate and persist in the human body for long periods of time and evidence from laboratory animal and human epidemiology studies indicates that exposure to these compounds may lead to cancer, reproductive, developmental, cardiovascular, liver, and immunological effects. Many known and potential sources of PFAS contamination are near communities already overburdened with pollution.

A Federal Register Notice has been published in the Federal Register at docket EPA-HQ-OLEM-2022-0922 and can be viewed on www.regulations.gov. The ANPRM will be open for a 60-day comment period through June 12, 2023.

EPA intends to carefully review all the comments and information received in response to this ANPRM.

An agency may publish an ANPRM in the Federal Register to seek input and obtain more information. If EPA decides to move forward with designating additional PFAS compounds as hazardous substances under CERCLA, the agency will publish a proposed rule and seek public comment.

EPA is not reopening or otherwise proposing to modify any existing regulations through this ANPRM.

Under the Roadmap, EPA is working across its programs and with its federal partners across the Biden-Harris Administration to develop solutions to the PFAS crisis and protect public health.

Hemp plants can suck PFAS, aka "forever chemicals," out of the ground

Hemp, a variety of the plant Cannabis sativa, is often overshadowed by marijuana — a genetically distinct form of cannabis. Used for food, clothing, fuel, and plastics, it’s the seemingly more domestic member of the family.


However, new research suggests we should pay more attention to this nonpsychoactive substance. Hemp, scientists say, has an eco-friendly superpower: It can rid the environment of toxic chemicals.


Members of the Micmac (Mi'kmaq) Nation — a tribe indigenous to what’s now known as Canada’s eastern Maritime Provinces and parts of the northeastern United States — the activist group Upland Grassroots, and research scientists came together in 2019 to test methods for removing per- and polyfluoroalkyl substances (PFAS) from land located at the Loring Air Force Base. After years of lobbying and dispute, portions of the former bomber base were given back to the Aroostook Band of Micmacs in 2018.


On Tuesday, the eclectic team published a commentary reflecting on their work and progress in the journal Cell Press. The project, so far, is a success: Results suggest planting small fields of fiber hemp removed a primary type of PFAS at the polluted site, a chemical called perfluorooctanesulfonic acid (PFOS).


“Protecting the land is part of the Micmac beliefs,” Chief E. Peter Paul of the Micmac Nation said in the commentary. “Anything we can do to contribute to making the environment better, we want to be a part of.”


What you need to know first — The idea of removing toxic contaminants from the soil by planting certain plants is known as “phytoremediation.”


Hemp is “versatile in extracting many different kinds of chemicals from the soil,” Chelli Stanley, a member of Upland Grassroots, states in the commentary.

Previous research has also demonstrated industrial hemp can be effective in phytoremediation.


“Hemp phytoremediation has been previously used for other types of soil contaminants – mainly metals,” Sara L. Nason, one of the lead researchers on the project, tells Inverse. Nason is a scientist affiliated with the Connecticut Agricultural Experiment station.
