EPA Proposes SNURs for Flame Retardants

/in , , /by

EPA has proposed significant new use rules (SNURs) for three flame retardants under the Toxic Substances Control Act (TSCA). The three flame retardants are tris(2-chloroethyl) phosphate (TCEP), tetrabromobisphenol A (TBBPA), and triphenyl phosphate (TPP).  All three substances are currently undergoing TSCA risk evaluations.  The proposed significant new uses are manufacture (including import) or processing for any use, except for those uses being considered in the risk evaluations.  In the Federal Register notice, EPA explained that significant new uses would encompass the following categories:

  • Manufacture and processing for uses that have ceased;
  • Manufacture and processing for uses that have not yet ceased but for which all manufacture and processing has ceased; and
  • Manufacture and processing for uses for which EPA has no information demonstrating that the use has previously commenced in the United States.

The Agency sought public comment on its description of the significant new uses for the chemicals identified, including specific documentation of ongoing uses not identified by the Agency in the risk evaluation scope documents.

EPA noted that “The issuance of a SNUR is not a risk determination itself, only a notification requirement for ‘‘significant new uses,’’ so that the Agency has the opportunity to review the [Significant New Use Notification] for the significant new use and make a TSCA section 5(a)(3) risk determination.”  In other words, “Once EPA receives a SNUN, EPA must either determine that the significant new use is not likely to present an unreasonable risk of injury or take such regulatory action as is associated with an alternative determination under TSCA section 5 before the manufacture (including import) or processing for the significant new use can commence.”

In its discussion of the significant new use determination, EPA explained that the Agency considered information about the toxicity or expected toxicity of these substances, likely human exposures and environmental releases associated with possible uses, and the four factors listed in TSCA section 5(a)(2):

  • The projected volume of manufacturing and processing of a chemical substance,
  • The extent to which a use changes the type or form of exposure of human beings or the environment to a chemical substance,
  • The extent to which a use increases the magnitude and duration of exposure of human beings or the environment to a chemical substance and
  • The reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce, and disposal of a chemical substance.

According to the Federal Register Notice, current uses of TCEP are as follows:  TCEP is imported into the United States and processed for commercial use in paints and coatings, for industrial or commercial use in polymers for use in aerospace equipment and products, and for commercial use as a laboratory chemical.

EPA found that TBBPA is currently manufactured (including imported) in the United States. It is processed as a reactant or intermediate to create other flame retardants; incorporated into formulation, mixture, or reaction products; and incorporated into articles. The Agency noted that the predominant uses for TBBPA are as a reactive flame retardant in electrical and electronic products and as an additive flame retardant in electrical and electronic products. In addition, epoxy resin containing TBBPA can be used in adhesives, laminate for aviation and automobile interiors and building/ construction materials.

The Agency reported that TPP is manufactured (including imported) in the United States.  It is processed as a reactant; incorporated into formulation, mixture, or reaction products; and incorporated into articles.  Commercial uses include in plastic and rubber products and in paints and coatings. The chemical is also used in lubricants and greases.  In addition, consumer uses were reported in foam seating and bedding products.

DuPont De Nemours Inc. Sues EPA Regarding GenX Test Order

/in , /by

Earlier this year, the US Court of Appeal for the Third Circuit ordered EPA to provide documentation regarding the Agency’s decision to order DuPont De Nemours Inc. to provide information on GenX chemicals through two section 4 test orders under the Toxic Substances Control Act (TSCA). DuPont brought this case to challenge the testing requirements imposed on the company, asserting that EPA had incorrectly identified the company as a manufacturer of the chemicals identified in the test orders:  hexafluoropropylene oxide (also known as trifluoro(trifluoromethyl)oxirane) and 6:2 Fluorotelomer sulfonamide betaine, two GenX chemicals. The test orders required testing on the inhalation effects toxicity of the chemicals in order to enable EPA to further understand protentional risks posed to human health and the environment. In addition to the cost of the toxicity studies, the manufacturers subject to the orders were assessed a fee of $11,650 to be split evenly amongst them.

After receiving the order to provide documentation, EPA requested several time extensions, but eventually stipulated to an agreement dismissing the case. The motion filed in May 2023 released DuPont from the test orders on 6:2 fluorotelomer sulfonamide betaine and hexafluoropropylene oxide. The Court then dismissed the case.

Audit Finds EPA’s New Chemicals Program Lacks Sufficient Guidance

/in , /by

On August 2, 2023, EPA’s Office of Inspector General (“OIG”) released a report on its audit of EPA’s New Chemicals Program. The audit identified recordkeeping and quality assurance issues with the program as administered by EPA’s New Chemicals Division (“NCD”). The audit, which began in October 2021, was conducted in response to several internal complaints submitted to OIG.

The New Chemicals Program reviews whether new chemicals or significant new uses of existing chemicals pose an “unreasonable risk” to human health or the environment under the Toxic Substances Control Act (“TSCA”). According to the report, NCD did not have finalized, up-to-date guidance for recordkeeping or for many of the steps in the new chemicals review process, contrary to EPA protocol.  OIG stated that these issues resulted from insufficient staff resources, which prevented NCD from both conducting the chemical reviews within statutory time frames and finalizing guidance for the activities composing the review process. The report also found frequent technical issues with NCD’s TSCA Confidential Business Information systems.

Some of the complaints to OIG alleged that staff were pressured to focus on deadlines rather than chemicals’ potential risks during the new chemical review process. However, OIG found no evidence of this; for example, the report notes that NCD employees were not evaluated on the speed at which they reviewed chemicals.

OIG made the following four recommendations to EPA’s Office of Pollution Prevention and Toxics (“OCSPP”) based on its findings:

  1. Develop a plan to regularly review NCD’s guidance documents,
  2. Develop a plan to periodically assess the effectiveness of NCD’s recordkeeping system,
  3. Develop a plan to identify the root causes of the technical issues, and
  4. Conduct periodic reviews of NCD’s workload.

OCSPP’s response, which was included in the report, agreed with each of OIG’s recommendations and proposed corrective actions in line with the recommendations.

This audit was not the first to find issues with EPA’s implementation of TSCA provisions. A 2019 GAO report identified similar issues, such as insufficient guidance and resources, with the new chemicals review process. In 2020, OIG found that EPA had missed deadlines on existing chemical risk evaluations and that EPA’s ability to meet future deadlines was at risk. EPA has since proposed a fee adjustment designed to increase TSCA fee collections. Most recently, in February 2023, GAO determined that EPA had missed most TSCA deadlines for reviewing new and existing chemicals.  In general, EPA agreed in part or in full when recommendations were made in these reports and corrective actions have been completed or are pending.

EPA Sued Over Herbicide Registration Renewal

/in , , /by

On June 6, 2023, the Center for Food Safety and two other environmental groups sued EPA over the Agency’s decision to renew registrations for Enlist One and Enlist Duo, two herbicides manufactured by Corteva Agrisciences, LLC.  The case is currently pending before the U.S. District Court for the District of Columbia as Center for Food Safety v. EPA.

The lawsuit alleges that EPA failed to properly evaluate the Enlist products’ risks as required by the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”) and the Endangered Species Act (“ESA”) when the Agency renewed the herbicides’ registrations until 2027.  According to the plaintiffs, the herbicides cause numerous adverse environmental effects, including harm to crops growing on neighboring properties and drinking water contamination.  The plaintiffs allege that EPA understated these risks in making its decision, while overstating the herbicides’ effectiveness.  In addition, the plaintiffs argue that EPA’s decision harms the survival, growth, and reproduction of exposed plants and animals, including endangered and threatened species.  The plaintiffs ask the court to vacate EPA’s decision and to stop the sale and use of the Enlist products.

In an EPA memorandum supporting the Agency’s decision, EPA stated that it had “evaluated the benefits and risks to human health and the environment from these products’ uses, including potential risk to non-target organisms, and conducted effects determinations for federally listed endangered and threatened species.”  According to EPA, the results of its evaluations and assessments were sufficient for the Agency to conclude that granting the registration renewal met the requirements of FIFRA and ESA.  These requirements include FIFRA section 3(c)(5), which directs EPA to register a pesticide when the Agency finds that the pesticide will not generally cause unreasonable adverse effects on human health or the environment, among other criteria; ESA section 7(a)(2), which requires EPA to consult with the Fish and Wildlife Service to ensure that actions taken by EPA do not jeopardize endangered and threatened species; and ESA section 7(d), which prevents EPA from taking irreversible action during 7(a)(2) consultation that eliminates the implementation of reasonable alternatives.

Enlist Duo has previously been the subject of litigation.  In National Family Farm Coalition, et al., v. U.S. EPA, et al., 966 F.3d 893 (9th Cir., 2020), petitioners challenged EPA’s decisions to register the herbicide in 2014, 2015, and 2017 on FIFRA and ESA grounds.  The panel rejected the petitioners’ ESA claims and the majority of the petitioners’ FIFRA claims, allowing Enlist Duo registration, but agreed with the petitioners that EPA did not properly assess harm to monarch butterflies due to the herbicide’s effects on milkweed.  The panel remanded the registration decision to EPA so the Agency could assess this concern and determine whether it presented an unreasonable adverse effect under FIFRA.

According to EPA, Enlist One and Enlist Duo are registered for use in 34 states for a variety of uses on corn, cotton, and soybeans.  Both herbicides contain the active ingredient 2,4-dichlorophenoxyacetic acid choline salt.  Enlist Duo also contains the active ingredient glyphosate.

EPA Finds TCE as a Whole Chemical Substance an Unreasonable Risk to Human Health

/in , /by

Earlier this year, EPA announced the final revision to the risk determination for trichloroethylene (TCE) risk evaluation issued under the Toxic Substances Control Act (“TSCA”). EPA found that TCE presents unreasonable risks to the health of workers, occupational non-users, consumers, and bystanders. The risks identified include adverse human health effects unrelated to cancer, such as neurotoxicity and liver effects, from acute and chronic inhalation and dermal exposures to TCE and risks for cancer from chronic inhalation and dermal exposures to TCE. The revised risk determination supersedes the conditions of use (“COU”) specific “no unreasonable risk” determinations that the EPA previously issued in its 2020 TCE risk evaluation.

TCE is a volatile organic compound (“VOC”) used mostly in industrial and commercial processes. Consumer uses include cleaning and furniture care products, arts and crafts, spray coatings, and automotive care products like brake cleaners. EPA determined that 52 of the 54 COUs evaluated drive the unreasonable risk determination.

EPA states that it used the whole chemical risk determination approach for TCE because there are benchmark exceedances for multiple COUs spanning across most aspects of TCE’s life cycle, from manufacturing (including import), processing, commercial use, consumer use, and disposal for health of workers occupational non-users (workers nearby but not in direct contact with this chemical), consumers, and bystanders. EPA holds that this approach is appropriate because the health effects associated with TCE exposures are “severe and potentially irreversible,” including developmental toxicity, reproductive toxicity, liver toxicity, kidney toxicity, immunotoxicity, neurotoxicity, and cancer. EPA notes that the revised risk determination for TCE does not reflect an assumption that workers always and appropriately wear personal protective equipment (PPE). EPA states that as it moves forward with a risk management rulemaking for TCE, it will “strive for consistency with existing OSHA requirements or best industry practices when those measures would address the identified unreasonable risk.

Additionally, EPA stated it is conducting a screening-level approach to assess potential risks from the air and water pathways for several of the first 10 risk evaluation chemicals, including TCE. The goal of the screening approach is to evaluate the surface water, drinking water, and ambient air pathways for TCE that were excluded from the 2020 risk evaluation and to determine if there are risks that were unaccounted for in that risk evaluation. EPA expects to describe its findings regarding the chemical-specific application of this screening-level approach in its proposed risk management rule for TCE.

Hearing Announced on EPA’s Intent to Cancel Chlorpyrifos Pesticide Registrations

/in , /by

On June 21, 2023, EPA announced that a public hearing will be held in response to objections and hearing requests following EPA’s issuance of a Notice of Intent to Cancel (“NOIC”) pesticide registrations for three products containing chlorpyrifos. The hearing will begin at 9 a.m. on January 8, 2024, and will continue as necessary through January 11, 2024.

The objections and hearing requests following the NOIC came from a collection of grower groups and a producer of chlorpyrifos products. The petitioners are currently challenging EPA’s 2021 final rule, which revoked all tolerances for chlorpyrifos, in the Eighth Circuit case Red River Valley Sugarbeet Growers Association et al. v. Regan. The petitioners argue that EPA should stay or withdraw the NOIC until the pending case is decided.

EPA’s NOIC was the result of over a decade of efforts to ban chlorpyrifos use. In 2007, two non-profit organizations filed a petition requesting that EPA revoke all tolerances and cancel all registrations for chlorpyrifos, pointing to studies showing neurotoxic, developmental, endocrinal, and carcinogenic effects in humans and animals as a result of exposure. EPA did not take final action on the petition until it denied the petition in 2017, concluding that the science behind the effects of exposure remained unresolved.  In 2021, the Ninth Circuit vacated EPA’s decision in League of United Latin Am. Citizens v. Regan. The court held that EPA had abdicated its statutory duty under the Federal Food, Drug, and Cosmetic Act by failing to update the tolerances for chlorpyrifos despite its inability to conclude, to the statutory standard of reasonable certainty, that present tolerances caused no harm. The court ordered EPA to grant the 2007 petition and modify or revoke the tolerances accordingly. EPA opted to revoke all tolerances in the final rule.

In the ongoing case, Red River Valley Sugarbeet Growers Association et al. v. Regan, the grower groups and the chlorpyrifos producer argue that the final rule was arbitrary and capricious due to EPA’s disregard for safe chlorpyrifos uses. The petitioners observe that shortly before the final rule was published, EPA completed a human health assessment that found that chlorpyrifos use on eleven crops in select regions was safe. By refusing to act on its own evidence, the petitioners assert that EPA disregarded its statutory mandate to review the safety of tolerances using current science.

According to EPA, chlorpyrifos was registered for use in the U.S. beginning in 1965. At the time of the final rule, chlorpyrifos was registered for use on fruit and nut trees, many types of fruits and vegetables, and grain crops.

EPA Proposes Ban on Perchloroethylene

/in , /by

Using its authority under the Toxic Substances Control Act (TSCA), EPA has released a proposed rule to ban the use of perchloroethylene (“PCE”) for most commercial and industrial uses. (PCE is also referred to as perc and tetrachloroethylene.) PCE is used in a number of applications and industries, including petroleum manufacturing, aerosol degreasing, and dry cleaning.

The proposed rule follows the Agency’s assessment of the risk to human health presented by the substance. EPA conducted a risk evaluation of the substance under TSCA section 6(b). That assessment determined that PCE, as a whole chemical substance, presents an unreasonable risk of injury to human health as PCE exposure causes a variety of adverse health effects. PCE is a known carcinogen; it also causes neurotoxicity, including impaired visual and cognitive function. Various other health effects were noted by the risk evaluation, including central nervous system depression, kidney and liver effects, immune system toxicity, and developmental toxicity.

Under TSCA section 6(a), EPA is required to address, by rule, any unreasonable risk of injury to health or the environment found during a TSCA risk evaluation. Section 6(a) also requires the Agency to identify actions necessary to ensure the chemical does not continue presenting an unreasonable risk by either a) implementing “a requirement [either] prohibiting or otherwise restricting the manufacturing, processing, or distribution in commerce of such substance or mixture,” or b) “limiting the amount of such substance or mixture which may be manufactured, processed, or distributed in commerce.” To meet these requirements, EPA is proposing to prohibit the manufacture, import, processing, and distribution of PCE for a number of commercial and consumer uses, such as in dry cleaning, spot-cleaning operations and degreasing. The prohibition allows a 10-year phaseout period.

The Agency will still permit limited use of PCE for some uses, particularly those which help its efforts in addressing climate-damaging hydrofluorocarbons (an initiative happening under the American Innovation and Manufacturing Act of 2020). PCE will also be used in uses that are important for national security applications or to meet other critical national needs. In these cases, EPA would require the implementation of a PCE workplace chemical protection program. The chemical protection program would include requirements to meet an inhalation exposure concentration limit and prevent direct dermal contact. The Agency has also put forward prescriptive requirements for laboratory use, recordkeeping, and downstream notification.

EPA will permit certain time-limited exemptions from the ban for certain critical or essential emergency uses of PCE when no alternative is technically or economically feasible safer alternative is available.

EPA’s First PFAS Clean Water Act Enforcement

/in , /by

On April 26, 2023, EPA announced that the Agency has taken the first federal Clean Water Act enforcement action for PFAS discharges.  The Agency ordered Chemours Company to follow corrective measures relating to exceedances of the limits set for per and polyfluoroalkyl substances (PFAS) in stormwater and wastewater discharges from the Washington Works facility in Parkersburg, WV.  The PFAS limits were set by in the company’s National Pollution Discharge Elimination System (NPDES) permits.

EPA issued an administrative order on consent (AOC) for the facility for exceeding permit limits on PFOA and HFPO Dimer Acid on more than 20 dates from September 2018 to March 2023.  The exceedances were documented in the discharge monitoring reports submitted by the company to the West Virginia Department of Environmental Protection – a permit requirement.  EPA also stated that Chemours was in violation of requirements for properly operating and maintaining all facilities and systems for permit compliance.  The AOC requires that Chemours take the following actions:

1) Implement a sampling plan to analyze PFAS and conduct analysis on the presence of PFAS in the stormwater and wastewater discharges.  The plan must be submitted to EPA for approval.

2) Submit and implement a PFAS treatment plan or minimizing plan to EPA for compliance with the permit limits.

3) Submit its existing Standard Operating Procedures for their management of wastewater for various systems and their revised Storm Water Pollution Prevention Plan.

In its press release, EPA noted that “Administrator Regan has directed EPA staff to use every enforcement tool at our disposal to compel manufacturers of PFAS to characterize, control, and clean up ongoing and past PFAS contamination,”

EPA Releases Chemical Data Reporting National Review

/in , , /by

EPA has released its first-ever Chemical Data Reporting (CDR) National Review (“Review”), which provides a comprehensive analysis of data submitted to the Agency during the 2020 CDR reporting cycle. The report presents information about chemicals that were manufactured and imported into the US from 2016 through 2019. In its press release on the Review, the Agency stated that the document will assist stakeholders in evaluating and understanding information about the types, quantities, and uses of chemicals produced domestically or imported into the U.S.

Manufacturers and importers of chemical substances listed on the Toxic Substances Control Act (“TSCA”) Inventory are required to report data to the EPA every four years if they manufacture or import substances at or above specific thresholds unless the chemical has been exempted from the reporting requirement. Typically reporting is required when an entity manufactures or imports 25,000 pounds or more of a chemical during any year in the reporting period at any single site. Companies must report how chemicals are processed or used (industrial processing and use data), and whether they are used in commercial or consumer products (commercial and/or consumer use data) in addition to manufacturing and import volumes.

According to EPA, the CDR database is the most comprehensive source of basic screening-level, exposure-related information on chemicals that is available to the Agency. EPA uses the database to screen and prioritize chemicals for further review.

The Review summarizes data from the most recent CDR reporting cycle data (2020), covering activities from 2016 to 2019, and provides trend data for reporting over the past decade. During this reporting period, more than 7.2 trillion pounds of chemicals were manufactured or imported at 5,238 sites.

The Review provides interactive trend analysis, including an interactive map of CDR sites and characteristics of the communities in which these sites are located.  It also includes maps displaying CDR reporting sites by state, and figures with production volumes. In addition, the Review contains informational charts and figures to increase understanding of a variety of CDR data elements, such as analyses of chemical use information. Environmental justice tools from EPA’s EJScreen, the Agency’s environmental justice mapping tool, are also contained in the document.

The Review’s key findings include:

  • Of the more than 8,000 chemicals reported for the 2020 CDR reporting cycle, about 54% were manufactured domestically, and 46% were imported. This is a 10% increase in imported chemicals from the 2016 CDR.
  • Two industry sectors manufactured and imported the bulk of the volume reported to the 2020 CDR: petroleum and coal products manufacturing (64%) and chemical manufacturing (14%). Although it produced less volume than the petroleum and coal products sector, the chemical manufacturing sector produced the majority of chemicals (84%) reported to the 2020 CDR and represented nearly half (43%) of all sites.
  • 180 PFAS were reported by 57 sites for a total production volume of about 678 million pounds.
  • Of the 37 Chemicals undergoing Risk Evaluation, 33 chemicals were reported to the 2020 CDR; that is, they were manufactured or imported at above threshold volumes (2,500 lbs.) in at least one year during the reporting cycle. Thirty-four Risk Evaluation chemicals were reported in both the 2012 and 2016 reporting cycles.
  • Total production volume for the 33 TSCA Risk Evaluation chemicals was about 38 billion pounds. The volume was reported across 254 sites.
  • The number of sites that manufactured and/or imported TSCA Risk Evaluation Chemicals has increased by 40% over the past 10 years, while the manufactured and imported volumes have generally remained consistent.

EPA Releases Draft National Strategy to Prevent Plastic Pollution

/in , /by

In April, EPA released the Draft National Strategy to Prevent Plastic Pollution. This strategy document, part of EPA’s Series on Building a Circular Economy for All, outlines voluntary actions aimed at eliminating plastic waste released into the environment from land-based sources by 2040. Under this plan, EPA seeks to reduce, reuse, recycle, collect, and capture plastic waste. The draft strategy comprises three primary objectives, each focusing on different aspects of plastic pollution prevention:

Objective A: Reduce pollution during plastic production

This objective emphasizes minimizing pollution throughout the life cycle of plastic products. It encourages manufacturers and consumers to implement upstream actions such as designing products for reuse and recycling, using less impactful materials, and controlling plastic production facilities. Proposed actions include reducing the production and consumption of single-use, unrecyclable, or frequently littered plastic products, as well as minimizing pollution across the entire life cycle of plastic products.

Objective B: Improve post-use materials management

While the National Recycling Strategy identified actions to enhance recycling, this objective expands the focus to other pathways of circularity, including reuse, refill, and composting. Proposed actions involve conducting a study of existing policies and incentives to evaluate their effectiveness, developing or expanding capacity for maximizing material reuse, facilitating effective composting, increasing solid waste collection, enhancing public understanding of plastic mismanagement, and exploring ratification of the Basel Convention for environmentally sound management of scrap and recyclables.

Objective C: Prevent trash and micro/nanoplastics from entering waterways and remove escaped trash from the environment

Proposed actions include implementing policies, programs, and compliance assurance measures to prevent trash and microplastics from entering waterways, improving water management to capture trash in waterways and stormwater/wastewater systems, increasing awareness of the impacts of plastic products in waterways, and coordinating research on micro/nanoplastics.

The agency aims to gauge the importance of different actions, identify key steps and milestones for successful implementation, determine the roles and actions federal agencies should lead, and evaluate potential unintended consequences on overburdened communities. EPA also seeks input on relevant metrics and indicators to measure progress and invites recommendations for additional actions to include in the strategy.
