On August 31, 2018, the U.S. Environmental Protection Agency (EPA) submitted to the Office of Management and Budget (OMB) for review a final rule regarding user fees for the administration of the Toxic Substances Control Act (TSCA). As reported in our February 9, 2018, memorandum, “Administrator Pruitt Signs TSCA User Fee Proposal,” as amended by the Frank Lautenberg Chemical Safety for the 21st Century Act, TSCA provides EPA the authority to levy fees on certain chemical manufacturers, including importers and processors, to “provide a sustainable source of funding to defray resources that are available for implementation of new responsibilities under the amended law.” Under the amendments to TSCA, EPA has authority to require payment from manufacturers and processors who:
- Are required to submit information by test rule, test order, or enforceable consent agreement (ECA) (TSCA Section 4);
- Submit notification of or information related to intent to manufacture a new chemical or significant new use of a chemical (TSCA Section 5); or
- Manufacture or process a chemical substance that is subject to a risk evaluation, including a risk evaluation conducted at the request of a manufacturer (TSCA Section 6(b)).
EPA’s February 26, 2018, proposed rule described the proposed TSCA fees and fee categories for fiscal years (FY) 2019, 2020, and 2021, and explained the methodology by which the proposed TSCA user fees were determined and would be determined for subsequent FYs. In proposing the new TSCA user fees, EPA also proposed amending long-standing user fee regulations governing the review of Section 5 premanufacture notices (PMN), exemption applications and notices, and significant new use notices (SNUN). Under the proposed rule, after implementation of final TSCA user fees regulations, certain manufacturers and processors would be required to pay a prescribed fee for each Section 5 notice or exemption application, Section 4 testing action, or Section 6 risk evaluation for EPA to recover certain costs associated with carrying out certain work under TSCA. EPA did not propose specific fees for submission of confidential business information (CBI).

The U.S. Environmental Protection Agency’s (EPA) release of its Toxic Substances Control Act (TSCA) Section 5(a)(3)(C) determination for P-16-0510 represents a significant step in EPA’s implementation of the New Chemicals Program under new TSCA. The substance is a polymer (a copolymer of ethylene glycol and propylene glycol end-capped with acrylamide groups). It is intended to be used as a deodorizer in a variety of products, including floor cleaners, cat litter, fabric freshener sprays, and other consumer products.
Notably, EPA’s determination document specifies the conditions of use that are intended, known, and reasonably foreseen. EPA states that there are no known or reasonably foreseen conditions of use other than those intended by the submitter. This may appear to be a controversial statement. Based on EPA’s interpretation of “conditions of use,” it would not pass legal muster to speculate that “anybody could manufacture or use it for anything” and, hence, impose use restrictions to prevent purely speculative applications with no basis in fact or reality. EPA has repeatedly stated that it would base what is reasonably foreseen on information, knowledge, or experience, not on any conceivable condition of use.
EPA identifies the new chemical’s potential health hazard endpoints based on the acrylate/acrylamide category. The concerns are based on acrylamide itself and some low molecular acrylamide analogs and include mutagenicity, developmental toxicity, reproductive effects, neurotoxicity, and a “marginal potential” for oncogenicity. This too may sound alarming. The real question, however, is how toxic is the new chemical and are exposures expected to exceed a “safe” level.
In this case, EPA specifically considers the low-molecular weight (LMW) components of the polymer (i.e., the “worst case”) in its assessment and identifies two analogs of the LMW components. Both analogs have similar structural features (they are end-capped with acrylates), so both are expected to share the same mode of action, and have similar molecular weights as the LMW components of the premanufacture notification (PMN) substance. EPA states that it also considered the toxicity of acrylamide in its assessment. We note, however, that acrylamide is not a good analog because it is substantially lower molecular weight than the LMW components of the PMN substance. Based on the identified analogs, EPA set a no observable adverse effect level (NOAEL) of 250 mg/kg/day for systemic toxicity based on a combined repeat dose/reproductive/developmental toxicity screening test (OECD 422). This study tests for a chemical’s potential to cause toxicity and the primary endpoints of concern relevant to the category (developmental, reproductive, and neurotoxicity). This NOAEL would put the substance in the low-to-moderate toxicity category. Note that despite the nominally alarming set of health endpoints identified in EPA’s category assessment, the 422 study shows the analog is not especially toxic to mammals. By way of contrast, EPA’s most recent Integrated Risk Information System (IRIS) assessment of acrylamide identified a NOAEL of 0.5 mg/kg-day.
EPA also identifies ecotoxicity concerns. Using its predictive models, EPA predicts toxicity levels for both acute and chronic effects to aquatic species and sets concentrations of concern (CoC) at 425 ppb for acute exposures and 43 ppb for chronic exposures. These levels put the substance in the “moderate” category for environmental hazard.
EPA then applies exposure modeling to predict exposures to workers, the general population, and consumers. EPA found that predicted exposures are sufficiently below EPA’s concern level to not present an unreasonable risk to workers, the general population, or consumers. EPA even found that at the “worst case” of 100 percent PMN substance, exposures would still be sufficiently below EPA’s concern level. EPA also evaluated surface water concentrations and found that the estimated maximum acute and chronic concentrations did not exceed the CoCs.
EPA reviewed the PMN, reviewed likely and potential exposures to workers, the general population, consumers, and aquatic species, and did not identify any foreseeable conditions of use that would lead EPA to predict that unreasonable risk was likely.
This is a marked and welcomed departure from previous TSCA Section 5(a)(3)(C) decisions. In nearly all cases in the past, EPA only made a not likely determination if it identified a low hazard for both health and ecological effects (“low/low” cases). Absent a low/low finding, EPA seemingly believed that there could be some conditions of use that could contribute exposures that could exceed EPA’s concern levels. Based on our review, EPA did not explain how it differentiated between “any possible/foreseeable” and “reasonably foreseeable” conditions of use. Instead, if EPA could imagine a set of circumstances that could elicit an exceedance, EPA was of the view that new TSCA precluded it from making a Section 5(a)(3)(C) finding. (While some stakeholders might applaud an approach based on concepts such as the European Union’s Precautionary Principle, this is not how new TSCA, or U.S. environmental legislation more generally, is structured.)
In the case of P-16-0510, EPA more carefully applied new TSCA as written when it identified a low/moderate health concern and a moderate eco concern, and nevertheless took a reasonable approach grounded on the law to go beyond mere consideration of potential hazard and to interpret the “reasonably foreseen” conditions of use and assess unreasonable risk as new TSCA requires. We support this more measured approach and believe it better meets the statutory intent and requirements. As we have written previously, in our view, a “not likely” finding is not limited to cases in which toxicity is so low that exceedances are unimaginable. Rather, EPA must limit its consideration to those conditions of use that are reasonably likely to occur and must evaluate unreasonable risks, not merely hazard, and regulate to protect to the “extent necessary” to protect against such unreasonable risks.
We applaud EPA’s more measured approach that likely indicates a maturation of its understanding of what is needed to meet a not likely determination. We urge EPA to articulate its thinking on what is and is not “reasonably foreseeable” and what PMN submitters can do to help EPA understand not only what is intended, but what might be reasonably foreseen to occur.

On June 25, 2018, the U.S. Environmental Protection Agency (EPA) held a preparatory meeting for experts selected to serve as letter peer reviewers for EPA's Exposure and Use Assessment and Human Health and Environmental Hazard Summary for five persistent, bioaccumulative, and toxic (PBT) chemicals. A list of those chemicals is available here. Although the meeting was scheduled for four hours, it adjourned after only two hours, as there were only a few questions from peer reviewers and only two outside stakeholders providing oral comments. Below are some highlights/takeaways from the meeting:
- All five PBT chemicals being reviewed scored high for hazard;
- Two PBT chemicals were pulled from EPA action under the Toxic Substances Control Act (TSCA) Section 6 because manufacturers requested risk evaluations for them prior to the September 19, 2016, deadline;
- Four of the PBT chemicals scored high or moderate for exposure; one scored low (pentachlorothiophenol (PCTP));
- For exposure assessment, EPA split up information as “core exposure data” or “supplemental exposure data”: core exposure data would be environmental data, monitoring, biomonitoring, modeled concentrations, or modeled dose; and supplemental exposure data would be environmental fate, engineering data, or other information related to exposure information or pathways;
- EPA identified exposure scenarios -- looking at source/use, environmental pathways, and receptors;
- EPA did not conduct any new modeling on the chemicals but did use modeled data from published literature;
- EPA did not conduct an exhaustive literature search, review, or assessment of hazard data, it used data readily available, as described in the Human Health and Environmental Hazard Summary; the EPA document “Supplemental Information for the Exposure and Use Assessment of Five Persistent, Bioaccumulative and Toxic Chemicals” outlines the literature search process used for exposure data; and
- Exposure scenarios include both quantitative and qualitative information.
No written comments were submitted prior to the peer review webinar. Only three people signed up for oral comments, and one was not present online. The two public commenters noted concerns regarding the likelihood of exposure, including the potential for accidental exposures; the lack of EPA focus on susceptible subpopulations; EPA’s intent not to address exposures that are already regulated under other EPA programs; and the need to assess the risk of bias.
Per the language in amended TSCA, EPA must issue risk management proposals to reduce exposures to the extent practicable by June 19, 2019.
Any public comments submitted by July 23, 2018, will be shared with peer reviewers. Comments submitted between July 23, 2018, and August 17, 2018, will be available to EPA for consideration. All comments are due by August 17, 2018. A recording of the webinar, slides, and other materials from the meeting will be posted in Docket EPA-HQ-OPPT-2018-0314. There are currently six supporting documents posted:

On May 25, 2018, the U.S. Environmental Protection Agency (EPA) announced it would host a half-day preparatory meeting for experts selected to serve as letter peer reviewers for EPA’s Exposure and Use Assessment and Human Health and Environmental Hazard Summary for Five Persistent, Bioaccumulative, and Toxic (PBT) chemicals. Section 6(h) of the Toxic Substances Control Act (TSCA) directs EPA to issue regulations under Section 6(a) for certain PBT chemical substances that were identified in EPA’s TSCA Work Plan for Chemical Assessments: 2014 update. The selected chemicals are:
- Decabromodiphenyl ethers (DECA);
- Hexachlorobutadiene (HCBD);
- Pentachlorothiophenol (PCTP);
- Phenol, isopropylated, phosphate (3:1) (PIP3/ITPP); and
- 2,4,6-Tris(tert-butyl) phenol (2, 4, 6 TRIS).
EPA prepared an Exposure and Use Assessment and a Human Health and Environmental Hazard Summary in response to the requirements under TSCA Section 6(h) to summarize conclusions of toxicity and whether there is likely exposure to these PBT chemicals and EPA organized letter peer reviews for the Exposure and Use Assessment and the Human Health and Environmental Hazard Summary. The Federal Register notice announcing the meeting states that during the preparatory meeting, “the individual letter peer reviewers will have the opportunity to comment on and ask questions regarding the scope and clarity of the draft charge questions.” EPA’s background papers, related supporting materials, and charge/questions for these letter peer reviews are now available in Docket No. EPA-HQ-OPPT-2018-0314 on www.regulations.gov.
The meeting is scheduled for June 25, 2018, from 1:00 p.m. to 5:00 p.m. (EDT) and will be held via teleconference and webcast only. Registration is available online. Those requesting to provide oral comments (approximately five minutes) are asked to register by June 21, 2018. Though the peer reviewers may not be able to consider fully written comments submitted after July 23, 2018, EPA will consider all comments submitted on or before August 17, 2018.
More information, including the list of experts, is available on EPA’s TSCA Peer Review website.

On June 6, 2018, the New York State Department of Environmental Conservation (NYSDEC) released its final policy and form for manufacturer disclosures under the Household Cleansing Product Information Disclosure Program. The Disclosure Program is similar to the recently enacted California Cleaning Product Right to Know Act of 2017 which requires the disclosure of cleaning product ingredients by way of website or product label. The Household Cleansing Product Information Disclosure Program requires manufacturers of cleaning products sold in New York to disclose chemical ingredients and identify any ingredients that appear on authoritative lists of chemicals of concern on their websites. New York states that it “will be the first state in the nation to require such disclosure and the State’s program goes beyond initiatives in other states by requiring the robust disclosure of byproducts and contaminants, as well as chemicals with the potential to trigger asthma in adults and children.” NYSDEC has posted the Household Cleansing Product Information Disclosure Program Certification Form and Program Policy and a response to comments.
Our recent memorandum provides an in-depth review of important information from the Disclosure Program Certification Form and Program Policy, including covered products and definitions, information to be disclosed, the lists of chemicals of concern covered by the Program, and the effective dates. With the first disclosures due July 1, 2019, manufacturers need to review the Program Policy and begin compiling information concerning the ingredients of their products.

On April 26, 2018, U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt was grilled by Members of the U.S. House of Representatives Committee on Energy and Commerce, Subcommittee on Environment at a hearing titled The Fiscal Year 2019 U.S. Environmental Protection Agency Budget. The budget was plainly not the primary topic as the House Committee Members covered a lot of ground. Pruitt fielded many questions and comments from House Democrats on his alleged ethical lapses regarding spending, security details, retaliation towards EPA employees who reportedly questioned his practices, and concerns about a hostile work environment. Lawmakers from both sides of the aisle expressed concern over the installation of a secure phone booth in his office. His opening statement addressed these criticisms only vaguely, stating that they are merely a distraction and an attempt to “attack and derail the President’s agenda and these administration’s priorities.” There were also questions concerning the delay of the proposed rule banning the use of methylene chloride, and criticism regarding EPA’s recent proposed rule to strengthen transparency in regulatory science (the “secret” Science Rule).
No attempt is made here to summarize the lengthy hearing.
Pruitt’s testimony statement is available here. It does not contain information on the Science Rule, but it briefly references the implementation of the Toxic Substances Control Act (TSCA) in a section entitled “Ensuring the Safety of Chemicals in Commerce.”
More information on the many TSCA implementation initiatives is available on our TSCA Reform News & Information webpage, as well as the TSCAblogTM. A summary of Pruitt’s testimony before the Senate Committee on Environment and Public Works is available in our blog item “Pruitt Addresses Legacy Issues, TSCA Implementation in Oversight Hearing.”

On April 24, 2018, the U.S. Environmental Protection Agency (EPA) is scheduled to publish a notice in the Federal Register that it will be adding a supplemental analysis, “Supplemental Analysis of Alternative Small Business Size Standard Definitions and their Effect on TSCA User Fee Collection,” to the rulemaking docket for the User Fees for the Administration of the Toxic Substances Control Act (TSCA) proposed rule published on February 26, 2018. EPA will also be extending the comment period for the proposed rule for an additional 30 days “to give interested parties the opportunity to consider this additional analysis and prepare meaningful comments.” Comments will be due within 30 days of publication (by May 24, 2018). The original comment deadline was April 27, 2018.
Regarding the supplemental analysis, EPA states that it “provides additional estimates for the impact of setting the small business definition based on an employee-based threshold.” More information on the proposed rule is available in our February 9, 2018, memorandum “Administrator Pruitt Signs TSCA User Fee Proposal.”

On February 26, 2018, the U.S. Environmental Protection Agency (EPA) published its proposed fees rule entitled User Fees for the Administration of the Toxic Substances Control Act (TSCA), as permissible under TSCA Section 26(b). 83 Fed. Reg. 8212. The rule as proposed will set user fees applicable to any person required to submit information to EPA under TSCA Section 4 or a notice, including an exemption or other information, to be reviewed by the Administrator under TSCA Section 5, or who manufactures (including imports) a chemical substance that is the subject of a risk evaluation under TSCA Section 6(b). The notice of proposed rulemaking provides a description of proposed TSCA fees and fee categories for fiscal years 2019, 2020, and 2021, and explains the methodology by which the proposed TSCA user fees were determined and would be determined for subsequent fiscal years. In proposing these new TSCA user fees, EPA also proposes amending long standing user fee regulations governing the review of premanufacture notices, exemption applications and notices, and significant new use notices. Comments on the proposed rule are due April 27, 2018.

On February 8, 2018, the U.S. Environmental Protection Agency (EPA) issued the prepublication version of its long-anticipated fees rule under amended Toxic Substances Control Act (TSCA) Section 26(b) entitled User Fees for the Administration of the Toxic Substances Control Act. EPA states that the proposed rule will set user fees applicable to any person required to submit information to EPA under TSCA Section 4 or a notice, including an exemption or other information, to be reviewed by the Administrator under TSCA Section 5, or who manufactures (including imports) a chemical substance that is the subject of a risk evaluation under TSCA Section 6(b).
EPA’s notice of proposed rulemaking provides a description of proposed TSCA fees and fee categories for fiscal years 2019, 2020, and 2021, and explains the methodology by which the proposed TSCA user fees were determined and would be determined for subsequent fiscal years. In proposing these new TSCA user fees, the Agency also proposes amending long standing user fee regulations governing the review of premanufacture notices, exemption applications and notices, and significant new use notices.
EPA states the proposed fees on certain chemical manufacturers, including importers, would go towards developing risk evaluations for existing chemicals; collecting and reviewing toxicity and exposure data and information; reviewing Confidential Business Information (CBI); and making determinations regarding the safety of new chemicals before they enter the marketplace.
Comments on the proposed rule will be due 60 days after its publication in the Federal Register.
An in-depth analysis prepared by Bergeson & Campbell, P.C. (B&C®) will soon be available on our Regulatory Developments webpage.
