On August 26, 2016, the U.S. Environmental Protection Agency (EPA) issued a notice of the establishment of a Science Advisory Committee on Chemicals (SACC) under Section 9(a) of the Federal Advisory Committee Act and pursuant to Section 26(o) of the Toxic Substances Control Act (TSCA), as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act.  The notice also solicits comments and requests nominations for new members of the SACC.  The SACC expects to meet in person or by electronic means (e.g., via webinar) approximately three to four times a year, or as needed and approved by the Designated Federal Officer (DFO) and its meetings will be held in the Washington, D.C. metropolitan area.

EPA’s notice states that the purpose of the SACC is to “provide independent advice and expert consultation, at the request of the EPA Administrator, with respect to the scientific and technical aspects of risk assessments, methodologies, and pollution prevention measures or approaches supporting implementation of [amended TSCA].”  The SACC will be composed of approximately 14 members who will serve as Special Government Employees or Regular Government Employees (RGE).  Nine of the 14 members of the SACC will most likely be selected from existing EPA Chemical Safety Advisory Committee (CSAC) members, and EPA will select five new members from among the candidates nominated via this notice and other sources.

CSAC members who are interested and available for the SACC include:

  • Holly Davies, Ph.D., Senior Toxicologist, Department of Ecology, State of Washington, Olympia, WA;
  • William Doucette, Ph.D., Professor, Department of Civil and Environmental Engineering, Utah State University, Logan, UT;
  • Panos G. Georgopoulos, Ph.D., Professor of Environmental and Occupational Health, Rutgers Biomedical and Health Sciences—School of Public Health, Rutgers, The State University of New Jersey, Piscataway, NJ;
  • Kathleen Gilbert, Ph.D., Professor, Department of Microbiology and Immunology, University of Arkansas for Medical Sciences, Little Rock, AR;
  • John Kissel, Ph.D., Professor of Environmental and Occupational Health Sciences, University of Washington, Seattle, WA;
  • Jaymie Meliker, Ph.D., Associate Professor, Program in Public Health, Department of Family, Population, & Preventive Medicine, Stony Brook University, Stony Brook, NY;
  • Kenneth Portier, Ph.D., Vice President, Statistics and Evaluation Center, American Cancer Society, Atlanta, GA;
  • Daniel Schlenk, Ph.D., Professor of Aquatic Ecotoxicology and Environmental Toxicology, University of California, Riverside, Riverside, CA; and
  • Kristina Thayer, Ph.D., Deputy Division Director of Analysis and Director, Office of Health Assessment and Translation, National Toxicology Program, National Institute of Environmental Health Sciences, Research Triangle Park, NC.

EPA states that nominated candidates should have:

  • [D]emonstrated high levels of competence, knowledge, and expertise in scientific/technical fields relevant to chemical risk assessment and pollution prevention and in particular, the nominees should include representation of the following disciplines, including, but not limited to: Human health and ecological risk assessment, biostatistics, epidemiology, pediatrics, physiologically-based pharmacokinetics (PBPK), toxicology and pathology (including neurotoxicology, developmental/reproductive toxicology, and carcinogenesis), and chemical exposure to susceptible life stages and subpopulations (including women, children, and others).

EPA is also considering the differing perspectives and breadth of collective experience needed to address EPA's charge to the SACC, as well as the following:

  1. Background and experiences that would contribute to the diversity of scientific viewpoints on the committee, including professional experiences in government, labor, public health, public interest, animal protection, industry, and other groups, as the EPA Administrator determines to be advisable (e.g., geographical location; social and cultural backgrounds; and professional affiliations);
  2. Skills and experience working on committees and advisory panels, including demonstrated ability to work constructively and effectively in a committee setting;
  3. Absence of financial conflicts of interest or the appearance of a loss of impartiality;
  4. A willingness to commit adequate time for the thorough review of materials provided to the committee; and
  5. Availability to participate in committee meetings.

EPA will publish the names, affiliations, and brief biographical sketches of the interested and available nominees in the Federal Register for a 30-day public comment period.  Comments and nominations are due by October 11, 2016.  Updates concerning the SACC will be available on EPA’s CSAC website.

The SACC needs to be populated with a diversity of skill sets and individuals who know how TSCA operates in real time.  Qualified industry representatives with solid TSCA credentials are urged to consider becoming a nominee to ensure the SACC represents the full spectrum of interests it was intended to reflect.

Section 6(h) of new TSCA addresses persistent, bioaccumulative, and toxic (PBT) chemical substances listed in the 2014 TSCA Work Plan.  For such chemicals, Section 6(h) outlines a procedure requiring “expedited” regulatory action that is intended to reduce exposures to these chemicals to the “extent practicable.”  As written, chemicals subject to Section 6(h) will not undergo a risk evaluation as will other high-priority chemicals.  Instead, EPA will proceed immediately to assess and identify appropriate risk management actions for these chemicals that EPA believes achieves the goal of reduced exposure to the “extent practicable.”  EPA is required under new TSCA to issue the proposed risk management rules by June 2019, or three years from enactment of new TSCA, and issue the final rules six months thereafter.

Importantly, manufacturers or other stakeholders of potential Section 6(h) chemicals can request that EPA conduct a risk evaluation prior to risk management decisions.  Section 6(h)(5) expressly allows entities to request such risk evaluations, effectively blunting expedited action.  The cost of the risk evaluation is borne by the entity requesting the evaluation.  Such requests must be received prior to September 22, 2016, a fast-approaching deadline.

This deadline plainly poses ups and downs.  On the one hand, absent a risk evaluation, fast tracking the process necessarily invites worst-case assumptions and a high degree of probability regulation actions will be extensive.  On the other hand, in the absence of a defined risk evaluation process and a yet-to be-defined fee assessment process or schedule, volunteers may be few and far between.  Understandably, a potential requester can be expected to want to know what the risk evaluation cost will be before making a commitment to pay that amount.  Nonetheless, even with these uncertainties, under some circumstances the election may be worth considering and stakeholders are urged to consider the risks and benefits quickly as September 22 is less than a month away.  Reportedly, EPA is preparing interim guidance for companies that wish to nominate a PBT for risk evaluation, and expects to issue it soon.

On August 11, 2016, the U.S. Environmental Protection Agency (EPA) convened a public meeting to solicit comments prior to development of a proposed rule to implement the revised Section 26 fees provision under the new Toxic Substances Control Act (TSCA).  Public comments may be submitted through in docket EPA-HQ-OPPT-2016-0401 until August 24, 2016.

During the meeting, EPA solicited public comment in particular on the following five issues:

  1. To be able to defray 25 percent of costs of administering Sections 4, 5 and 6, and Confidential Business Information (CBI), does industry have considerations of weight amongst the three areas of fee collection?
  2. Does industry have thoughts on the types of factors (types of submissions, numbers of submissions, level of difficulty, etc.) that EPA should consider when structuring the fees?
  3. Has industry considered how to distribute payment amongst multiple manufacturers and/or processors?
  4. Does industry have thoughts on how to identify the whole universe of manufacturers, including importers and processors affected?
  5. Does industry have thoughts on how to arrive at an appropriate balance between manufacturers and processors?

In its presentation, EPA stated that it intends to publish a proposed rule by mid-December 2016, and a final rule in time for its statutory June 22, 2017, deadline.

Four industry trade associations gave prepared remarks during the meeting:  the American Chemistry Council; the American Petroleum Institute; the Society of Chemical Manufacturers and Affiliates; and the American Fuel & Petrochemical Manufacturers.  Their comments reflected several common but competing themes, including:

  • EPA needs to share its expectations of internal costs as a starting point for discussions of the fee structure.
  • The fee system should be straightforward to implement.
  • EPA should be mindful in developing a fee structure so as not to stifle innovation; for example, placing too high of fees for review of new chemistries under Section 5 or confidentiality claims under Section 14.
  • Not all sections should be given equal weight; in particular, as industry will pay for Section 4 data development, it should not be double-charged by assessing a fee for EPA’s review of these data.
  • EPA must provide adequate consideration for the effect on small businesses.
  • Consideration should be given to incremental fees, tied to EPA milestones.
  • A business should have a way to exit from a Section 6 risk evaluation process if it elects to exit the market.


Congress recognized that the new TSCA tasks EPA with significant additional responsibilities, and included Section 26 as a venue to ensure adequate resources would be available to develop the infrastructure to meet these responsibilities according to the specified timelines and in conformity with sound science.  Input from all affected stakeholders will be needed to devise a workable TSCA fee system, particularly in the compressed timeframe for rule development. 

EPA and industry stakeholders are supportive of a simple framework, but the complexities and current unknowns of how new TSCA will operate will make this goal challenging.  Many questions exist that will not be answered before next week’s comment deadline:

  1. Should a company have to pay fees for a Section 6 risk evaluation on uses that it does not support? 
  2. Should there be fees associated with Section 6 prioritization actions?  If not, does that mean that only high priority chemicals will have Section 6 fees assessed on them? 
  3. Given the new threshold for affirmative findings under Section 5, will EPA complete the same number of new chemical notifications that it has in the past?  If not, should that anticipated reduction in notification reviews be reflected in the fees proposal? 
  4. Most industry stakeholders recognize that the current PMN fee of $2,500 will be increased, but how much is too much?   
  5. As previously noted, is it appropriate to require industry to pay for testing under Section 4, and then charge for EPA review of that test data? 
  6. To ensure that sufficient funds are raised, will we need to assess a fee for every “touch” that EPA has within Sections 4, 5, and 6?  How can that cost be fairly allocated among all industry players, including small businesses?

While EPA did not offer to share information on budgets at the August 11, 2016, meeting, the Office of Pollution Prevention and Toxics (OPPT) presumably has pertinent information supporting its annual budgets that must be shared in the near term if it hopes to receive any meaningful ideas on a proposed fee structure.  Although past program outputs done under old TSCA may bear little resemblance to the duties EPA now has under new TSCA, EPA’s new policies and responsibilities will be some scale of past program capabilities and budget.

Of more relevance will be the experience of OPPT’s sister program, the Office of Pesticide Programs (OPP).  OPP has had a dedicated stream of user fees since the 1988 amendments to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and additional fees were imposed in 2004 with enactment of the Pesticide Registration Improvement Act (PRIA) fee-for-service program.  While the FIFRA product licensing program is different in many respects from TSCA, there are relevant commonalities that OPPT should find helpful.  OPP has a time accounting system, for example, that provides a principled basis on which to estimate the time required for study report review and risk evaluation. 

With estimates derived from the time accounting system, OPP (and presumably OPPT) can estimate how much it costs EPA to review toxicity studies individually.  For example, there is an estimate of how much it costs EPA to review a 90-day subchronic study, or how much to review a genotoxicity study. These calculations form the basis of the PRIA fee scheme, as PRIA is designed to generate one-third of the program costs involved.  The “simple” general rule underlying a now elaborate fee schedule with almost 200 categories is that the more science review involved, the greater the required fee.  The new law may not need or want to have so many different categories, but the operating principle can remain the same.

For OPPT, the dollar amounts could vary from OPP given the statutory limitation of the maximum amount to be generated, but the more difficult question will be how OPPT calculates its expected workload under the new law.  Given the wealth of information available through OPP’s experience, sharing this information would further inform the public about what to expect in, or options for how to fashion, a fee scheme.

On August 9 and August 10, the U.S. Environmental Protection Agency (EPA) held two public meetings to obtain input prior to development of a proposed rule for chemical risk evaluation (August 9) and a proposed procedural rule regarding prioritization of chemicals for further risk evaluation (August 10) under the new Toxic Substances Control Act (TSCA).  Bergeson & Campbell, P.C.’s (B&C®) Oscar Hernandez, Ph.D. and Richard E. Engler, Ph.D. were in attendance, and offer the following highlights.

On August 9, many speakers across different stakeholder groups flagged issues in terms of how EPA should conduct the chemical risk evaluation process:

  • EPA must determine compatibility of information from third parties, e.g., assessment documents from other groups including within EPA, with TSCA Section 26 standards;
  • EPA needs to improve its exposure methodologies, and develop new ones; EPA needs to modify its exposure ranking to acknowledge that chemical intermediates are typically consumed in the manufacture of a product and do not represent a primary source of exposure, especially outside of the production facility;
  • Transparency throughout the risk evaluation process is critical;
  • EPA is required to use best available science and weight-of-evidence;
  • Potentially exposed and susceptible subpopulations should include workers, pregnant women, infants, fence-line populations, and consider the lifestyles (especially diets) of native populations as appropriate under the conditions of use; and
  • EPA should undertake a tiered approach to testing, to minimize vertebrate testing and cost, as new TSCA requires.

As for the content of the actual chemical risk evaluation rule, stakeholders made the following comments:

  • The rule should include more content beyond procedures by incorporating definitions for key items such as “weight of scientific evidence” and other scientific standards, and codifying criteria for evidence evaluation;
  • The final reports should explicitly identify low exposure/low risk uses considered in the development of the Risk Evaluation; and
  • Whether legal scientific requirements under TSCA Sections 6 and 26 need to be reflected in the procedural rule, and not be relegated to guidance documents – there was some disagreement on the best course of action on this issue.

On August 10, comments made during the prioritization procedural rule meeting sessions were similar to those made at the August 9 meeting, with an emphasis on the application of Section 26 scientific standards.  A few speakers expressed reservations about the prioritization methodology that EPA currently uses and suggested some alternative approaches.

On August 11, 2016, the Bloomberg BNA Daily Environment Report quoted Kathleen M. Roberts, Vice President of B&C® Consortia Management, L.L.C. (BCCM), an affiliate of Bergeson & Campbell, P.C. (B&C®), on the implication of additional fees created by Toxic Substance Control Act (TSCA) reform.

Companies that pay the costs of generating toxicity, exposure and other data should not be “double billed” through additional fees to review the resulting information, said Walls and Kathleen Roberts, vice president of Bergeson & Campbell Consortia Management, LLC.


On July 28, 2016, the U.S. Environmental Protection Agency (EPA) proposed to update the Toxic Substances Control Act (TSCA) Significant New Use Rule (SNUR) procedures. 81 Fed. Reg. 49598. As discussed in our previous memorandum on this proposed rule, Proposed Revisions to Significant New Use Rules Reflect Current Occupational Safety and Health Standards, while some of the proposed changes are not consequential, other changes, such as those related to workplace protections, are more clearly consequential. An issue that was noted but not discussed in detail in our previous memorandum is EPA's proposal to modify the procedures for determining if a specific substance or chemical use is subject to a SNUR when the substance, production volume, or use is claimed as confidential business information (CBI). Specifically, EPA has proposed changes to 40 C.F.R. § 721.11 to address these procedures. Below, we review the current procedures and then address how the proposed language would change those procedures -- changes of which stakeholders should be aware.

To put the changes into context, we first consider the current regulations relating to establishing a bona fide intent to manufacture (bona fide intent) a substance that has confidential identity or confidential conditions in a SNUR. Under the current procedure, determining if a specific substance is listed on the confidential portion of the TSCA Inventory (Inventory) and if the substance is subject to a SNUR requires the submission of a bona fide intent notice (BFN), according to the procedures codified at 40 C.F.R. § 721.11(b). If EPA determines that the submitter has established a bona fide intent, EPA will inform the submitter that the substance is listed on the Inventory and provide "which section in subpart E of this part [40 C.F.R. § 721] applies." This provision would not necessarily reveal any CBI information regarding use or production volume restrictions that are conditions of the SNUR, only the specific 40 C.F.R. § 721 citation.

Whether the identity of a substance is confidential or not, the substance may have SNUR restrictions applied to it that are considered CBI. In particular, production volume and/or specific use(s) may be considered CBI and be part of a SNUR imposed on the substance. The procedures for determining the confidential SNUR restrictions are similar to the procedures to determine if a substance is listed on the confidential portion of the Inventory. It requires submitting a BFN to EPA. In the past, when EPA needed to refer to the procedures for submitting a BFN to determine the confidential SNUR conditions, it referred to the procedures codified at 40 C.F.R. § 721.1725(b)(1). This is in contrast to the BFN procedures for determining if a specific substance is subject to a SNUR listed in 40 C.F.R. § 721.11(b).

To put these changes in context, let us first examine the current procedures for EPA's response to a BFN submitted to determine the CBI provisions of a SNUR. 40 C.F.R. § 721.1725(b)(1)(iv) states:

If EPA determines that the person has a bona fide intent to manufacture, import, or process the chemical substance, EPA will tell the person whether the use for which the person intends to manufacture, import, or process the substance is a significant new use [(SNU)] under paragraph (a)(2)(i) of this section. If EPA tells the person that the intended use is not a significant new use under paragraph (a)(2)(i) of this section, EPA will tell the person what activities would constitute a significant new use under paragraph (a)(2)(ii) of this section.

This means that upon making its determination that a submitter has demonstrated a bona fide intent, EPA either:

  1. Tells the BFN submitter that the use specified in the BFN is a SNU, in which case the submitter must prepare and submit a Significant New Use Notice (SNUN) at least 90 days prior to manufacturing the substance for the particular use of the substance; or
  2. Tells the BFN submitter that the use specified in the BFN is not a SNU, in which case EPA tells the submitter what activities would constitute a SNU for the substance.

Note that in the first scenario, where a SNUN is required, EPA does not inform the submitter of the existing confidential SNUR conditions. EPA subsequently makes a determination based on the information in the SNUN when submitted, and informs the SNUN submitter of any restrictions imposed to manage risks associated with the use described in the SNUN. The new restrictions could either be unique to the conditions of the SNUN or could result in a modification of the previously established CBI SNUR restrictions. Also, EPA could amend the confidential portion of the SNUR to include any new permissible activities as a result of the SNUN (e.g., add another CBI use) without informing either manufacturer of the other's confidential SNUR conditions.

In the second scenario, where EPA determines that the BFN submitter's use is not a SNU, EPA informs the BFN submitter of any restrictions associated with that use that might further restrict the BFN submitter or its customers (e.g., the BFN submitter's use is permitted, but that the production volume is capped by the SNUR). As a matter of practice, EPA informs the original submitter that another submitter has demonstrated a bona fide intent, but this practice is not codified in the C.F.R. Furthermore, the original submitter is not informed of the BFN submitter's intent, only that the BFN submitter's use was not a SNU, whereas the BFN submitter knows the heretofore confidential specific use and production volume ceiling (if any). These two outcomes are not aligned. The first scenario is more protective of both entities' CBI. The second scenario provides the BFN submitter some visibility of the original submitter's CBI, but not the reverse.

For example: Manufacturer 1 submits a premanufacture notice for a non-confidential chemical substance to be used as an intermediate to manufacture a pesticide and claims the use as confidential (with a generic use of "intermediate"). EPA makes a determination that the use specified in the PMN does not present an unreasonable risk to health or the environment, but other uses may present issues, so EPA imposes a SNUR invoking 40 C.F.R. § 721.80(j) limiting its use to the use listed in the PMN (intermediate to manufacture a pesticide). Manufacturer 1 then commences commercially manufacturing the substance and files a Notice of Commencement (NOC), placing the substance on the public portion of the Inventory. Some time later, Manufacturer 2 seeks to use the same substance as an intermediate to manufacture an anti-oxidant lubrication additive. Manufacturer 2 submits a BFN and EPA informs Manufacturer 2 that its use is a SNU. Manufacturer 2 then submits a SNUN for its use, also claiming the specific use as confidential and listing "intermediate" as the generic use. EPA evaluates the SNUN and determines that this particular use is not likely to present unreasonable risk to health or the environment, but other uses may present issues, so EPA adds the new use to the confidential uses permitted for the substance, but leaves the other SNUR provisions in place and neither manufacturer knows the specific use of the other.

We note that manufacturers must communicate SNUR restrictions to their customers. 40 C.F.R. § 721.5 requires that to avoid submitting a SNUN, each manufacturer must provide the SNUR conditions to its customer(s). 40 C.F.R. § 721.5(a)(2) requires that "[a] person who intends to manufacture, import, or process for commercial purposes a chemical substance [with a SNUR], and intends to distribute the substance in commerce" must submit a SNUN. Most manufacturers avoid this SNUN requirement by taking advantage of the provisions of 40 C.F.R. § 721.5(a)(2)(i) that state that a SNUN is not required if the manufacturer can document:

That the person [manufacturer] has notified the recipient [customer], in writing, of the specific section in subpart E of this part which identifies the substance and its designated significant new uses.

In the example above, each manufacturer notifies its own customers of the appropriate C.F.R. citation and SNUR restrictions (Manufacturer 1 informs its customer that the use is limited to use as an intermediate for a pesticide; Manufacturer 2 informs its customer that the use is limited to use as an intermediate for an antioxidant). The customers of each manufacturer remain in compliance with the SNUR and 40 C.F.R. § 721.5, assuming each customer restricts its use based on the information provided by the separate manufacturers. In this scenario, all four parties (both manufacturers and both customers) can be in compliance without EPA disclosing the confidential use of one manufacturer to the other.

EPA has proposed incorporating the BFN procedures for determining whether an activity is a SNU under the confidential provisions of a SNUR into 40 C.F.R. § 721.11(a) (the proposed key changes are emphasized):

A person who intends to manufacture or process a chemical substance which is subject to a significant new use rule in subpart E of this part may ask EPA whether the substance or a proposed use is subject to the requirements of this part if that substance is described by a generic chemical name or if the significant new use is confidential and therefore not described specifically in the rule. EPA will answer such an inquiry only if EPA determines that the person has a bona fide intent to manufacture or process the chemical substance for commercial purposes.

This change is innocuous. It simply incorporates the two BFN procedures into a single paragraph. EPA's proposal on procedures for its response to such a BFN, proposed to be codified at 40 C.F.R. § 721.11(e) alters procedures for how EPA responds (again, proposed key changes emphasized):

If the manufacturer or processor has shown a bona fide intent to manufacture or process the substance and has provided sufficient unambiguous chemical identity information to enable EPA to make a conclusive determination as to the identity of the substance, EPA will inform the manufacturer or processor [the BFN submitter] whether the chemical substance is subject to this part and, if so, which section in subpart E of this part applies, and identify any confidential significant new use designations.

Under the proposed rule, once a submitter has established a bona fide intent, EPA will disclose to the BFN submitter any confidential significant new use designations, including specific use and production volume restrictions, whether or not those restrictions are relevant to or would limit the BFN submitter's commercial activity as proposed in the BFN. As proposed by EPA, this disclosure would be made to the BFN submitter without regard for the existing CBI claims on the information, and without informing the original entity holding the CBI claim before or after making this disclosure.

Importantly, this change means that EPA is switching from a presumption of protecting CBI in the SNUR to actively informing later submitters of information proprietary to the original submitter. While 40 C.F.R. § 721.11(f) states that informing later submitters of SNUR restrictions "will not be considered public disclosure of [CBI] under Section 14," it is an unavoidable fact that EPA's proposed approach involves disclosure of CBI to an additional party, one that could be a competitor to the original submitter (both are, after all, manufacturing the same substance), a fact pattern that is very likely to be of considerable concern to the original submitter.

We do not read provisions in either old or new TSCA to authorize EPA to disclose CBI in the way that is proposed in this notice. The CBI SNUR requirements do not fall into any of the information types discussed under Section 14(b) of new TSCA that concerns information not protected from disclosure. The BFN submitter cannot be considered to have official duties or needs related to those discussed at Section 14(d) of new TSCA, the provision that allows CBI disclosure under certain circumstances. The BFN submitter only needs to know if the proposed use is a SNU or not. If EPA informs the BFN submitter that the proposed use is not a SNU, the BFN submitter is effectively bound to the use terms laid out in the BFN and would need to submit a new BFN if other uses or changes in the initially proposed use are contemplated.

Based on the foregoing, with the proposed language, the second submitter is unavoidably privy to the CBI claimed by the first submitter, but there is no provision in the C.F.R to inform the first submitter of the conditions sought by the second submitter. This is in contrast to the provisions in 40 C.F.R. § 720.25(b)(6) in which the original submitter is notified if and when a second entity has demonstrated a bona fide intent that is listed on the CBI portion of the Inventory. Both the original submitter and the BFN submitter are informed that another entity is manufacturing the substance for a TSCA purpose.

EPA must provide the statutory basis and rationale for informing a BFN submitter of confidential use or production volume conditions. If EPA can provide the statutory basis for such disclosure, EPA must also explain why it must disclose such information to the BFN submitter. If EPA can somehow justify disclosing the CBI SNUR conditions, it should codify its obligation to notify the original CBI submitter that such disclosure has occurred. The current proposed SNUR provides for neither equal disclosure nor equal confidentiality as a result of BFN submission.

TSCA stakeholders should carefully consider commenting on the changes to 40 C.F.R. § 721.11 to be sure that EPA is acting within its statutory authority, justifying why disclosure is necessary, and providing for notification of the original CBI holder. While the consequences of these proposed provisions may be inadvertent, the proposed rule either needs to be withdrawn and re-proposed to reflect the law, or rationalized in a way that our careful reading of TSCA does not allow.

The U.S. Environmental Protection Agency (EPA) proposed on July 28, 2016, revisions to the regulations governing significant new uses of chemical substances under the Toxic Substances Control Act (TSCA) with revisions to the Occupational Safety and Health Administration’s (OSHA) Hazard Communications Standard (HCS) occasioned by OSHA’s March 2012 final rule modifying the HCS to conform to the United Nations’ (U.N.) Globally Harmonized System of Classification and Labelling of Chemicals (GHS), changes to OSHA’s Respiratory Protection Standard, and the National Institute for Occupational Safety and Health (NIOSH) respirator certification requirements pertaining to respiratory protection of workers from exposure to chemicals.  EPA states that it is also proposing changes to regulations based on issues that it identified, as well as issues raised by public commenters, for significant new use rules (SNUR) previously proposed and issued under these regulations.  Additionally, EPA claims to propose a “minor” change to reporting requirements for premanufacture notices (PMN) and other TSCA Section 5 notices.  EPA states that it expects the changes “to have minimal impacts on the costs and burdens of complying, while updating the significant new use reporting requirements to assist in addressing any potential effects to human health and the environment.”  Comments are due September 26, 2016.

The revisions include:

  • Proposed Changes to 40 C.F.R. Section 721.63, Protection in the Workplace;
  • Proposed Changes to 40 C.F.R. Section 721.72, Hazard Communication Program;
  • Clarification of the Use of 40 C.F.R. Section 721.80, Industrial Commercial and Consumer Activities;
  • Proposed Changes to 40 C.F.R. Section 721.91, Computation of Estimated Surface Water Concentrations:  Instructions;
  • Proposed Changes to 40 C.F.R. Section 721.11, Determining Whether a Chemical Substance or a Specific Use Is Subject to This Part When the Chemical Substance Identity or Significant New Use Is Confidential;
  • Proposed Changes for Submission of SDS(s) with PMNs, SNUNs, Low Volume Exemptions (LVE), Low Release and Exposure Exemptions (LoREX), and Test Marketing Exemption (TME) Applications; and
  • Fixing Typographical Errors and Other Non-Substantive Changes.


Although the notice downplays them, the proposal raises significant and complex issues.  There may well be good reasons for several of the proposed changes.  The minimal discussion provided in the notice and the lack of adequate public debate having occurred prior to its issuance raise troubling questions about the legal basis for, scope of, and complexity of the proposed changes, some of which may apply retroactively. The confusion the proposal can be expected to cause could have been avoided had adequate discussion preceded its publication, or at the least EPA could have raised these issues in the proposed rule’s preamble to focus stakeholders’ attention appropriately.

On July 26, 2016, the U.S. Environmental Protection Agency (EPA) issued a notice in the Federal Register soliciting a second round of comments on the burdens and value of information it periodically collects addressing significant new use rules (SNUR) for existing chemicals.  Specifically, EPA submitted a request to renew the approval of an existing information collection request (ICR), Toxic Substances Control Act (TSCA) Section 5(a)(2) SNURs for Existing Chemicals, to the Office of Management and Budget (OMB).  This notice provides chemical manufacturers and other interested parties a second opportunity to comment on certain questions, specifically:  whether the agency accurately estimated the burden of responding to SNURs that it issues for chemicals in commerce; whether the agency could minimize the burden; and whether the information it collects is necessary. 

The first ICR was issued on September 2, 2015, and comments were due November 2, 2015.  Only two comments were filed in response to the initial ICR, by the American Chemistry Council (ACC) and the Society of Chemical Manufacturers & Affiliates (SOCMA), two trade associations.  ACC and SOCMA stated in their comments that EPA underestimated the burdens its SNURs impose on chemical manufacturers and their customers.

This renewed ICR states that EPA estimated that six companies would be affected by its new use rules for existing chemicals, creating an estimated total burden of 1,025 hours per year and a cost of $100,595.

Comments are due August 25, 2016.


SNURs are deeply unpopular to some in the chemical community and welcomed outcomes of the premanufacture notice (PMN) or significant new use notification (SNUN) process to others.  Most would agree that the cost of compliance with a SNUR can be difficult to estimate with any degree of precision.  Some of us are also of the view that TSCA, as recently amended, may result in many more SNURs given the new “determination” requirements under TSCA Section 5(a).  The comment period opened by today’s Federal Register notice provides an excellent opportunity to provide comment to EPA and thus help to ensure that EPA has an accurate and current basis upon which to estimate the cost.

On July 25, 2016, the U.S. Environmental Protection Agency (EPA) announced its intention to hold two public meetings on August 9, and August 10, 2016, to obtain input on the processes that will be used to prioritize and evaluate chemicals under the Toxic Substances Control Act (TSCA), as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act:

  • August 9, 2016:  EPA states that this public meeting will inform its proposed rule on conducting risk evaluations to determine whether a chemical presents an unreasonable risk of injury to health or the environment; and
  • August 10, 2016:  EPA states that this public meeting will inform its proposed rule to establish a risk-based process for chemical prioritization.

The public meetings are scheduled for 9:30 a.m. to 4:30 p.m., and will be held at the Ronald Reagan Building and International Trade Center, Horizon Ballroom, 1300 Pennsylvania Avenue, N.W., Washington, D.C. EPA states that the input obtained during these meetings will be considered as the EPA develops its proposed procedural regulations for risk evaluation and chemical prioritization.  EPA is recommending that any interested participants register in advance.  

More information concerning EPA’s implementation of the amended TSCA is available in our memorandum EPA Publishes First Year Implementation Plan, as well as on the Bergeson & Campbell, P.C. (B&C®) website under Regulatory Developments: TSCA.


It is critically important that stakeholders attend and participate in these meetings. While the timing is regrettable in light of vacation schedules, EPA is under intense pressure to issue rules later this year and EPA has no choice other than to keep the process moving.  EPA is to be commended for scheduling these opportunities as quickly as it has, and its efforts should be acknowledged by robust stakeholder engagement.


On July 22, 2016, the U.S. Environmental Protection Agency (EPA) posted on its website the first four Section 5(a)(3) determinations for premanufacture notices (PMN) under the Toxic Substances Control Act (TSCA) as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act (Pub. L. No. 114-182) (new TSCA). All four of the new chemicals were determined to satisfy the "not likely to present an unreasonable risk" determination at Section 5(a)(3)(C). It is notable that all four determinations relied on structure activity relationship (SAR) analyses and data on analogs.

In all four cases, EPA found low potential for health hazards and low potential for environmental hazards (low/low). EPA estimated that each substance has some degree of persistence (from limited persistence to very persistent) and that all four have a low potential for bioaccumulation. Based on our experience with the new chemicals program under TSCA prior to new TSCA, when EPA made a low/low hazard call and either a low potential for persistence or a low potential for bioaccumulation, EPA "dropped" the submissions from further review, avoiding the time and expense of performing exposure assessments on substances of low potential hazard.

Under new TSCA, to make a Section 5(a)(3)(C) determination, EPA must identify potentially exposed or susceptible subpopulations (PESS) that are relevant under conditions of use. In these four Section 5(a)(3)(C) determinations, EPA identified known or reasonably foreseeable uses in addition to the uses identified in the PMNs. EPA identified the PESS under the intended use as workers for all four cases. We note that EPA identified consumers as a PESS if the substance notified in P-15-0281 was to be used as a lubricant or lubricant additive (the known or reasonably foreseen use that EPA identified). Even considering the PESS, EPA has concluded that a low hazard finding is sufficient to support a "not likely to present" finding under Section 5(a)(3)(C) and did not perform a formal exposure assessment. Since EPA has published the Section 5(a)(3)(C) findings, per Section 5(g), the submitters of these four PMNs may commence manufacturing without waiting for the remaining portion of the 90-day review period to expire.

PMN Generic name Use(s):
Persistence Bioaccumulation Health Hazard Environmental Hazard
P-16-0281 Fatty alcohols-dimers, trimers, polymers Reactive polyol
Lubricant and lubricant additive
Persistent Low Low Low
P-16-0292 Depolymerized waste plastics Intermediate for use in manufacture of polymers
Lubricant and lubricant additive
Very Persistent Low Low Low
P-16-0301 Propyl silsesquioxanes, hydrogen-terminated Intermediate
Lubricant and lubricant additive
Limited Persistence Low Low Low
P-16-0302 Organic modified propyl sisesquioxane Plastic additive
Finishing agent
Very Persistent Low Low Low


EPA determined that all four new chemicals satisfy the "not likely to present an unreasonable risk" determination under Section 5(a)(3)(C). The conditions of use for these chemicals indicate industrial scenarios that would point to workers as the PESS. The potential exposure to workers was not estimated. Instead, the determination of not likely to present an unreasonable risk hinges on the low hazard potential for these chemicals. Three of the four chemicals were estimated to be persistent with two categorized as very persistent. The chemicals were estimated to have low potential for bioaccumulation. No information was provided about potential releases to water.

It is reassuring that the SAR was used to reach determinations about persistence, bioaccumulation, and hazard potential, including mention of category analysis. This suggests that EPA intends to maintain SAR as a basic component in its evaluation of new chemicals consistent with the provisions at Section 4(h) to reduce vertebrate animal testing and to maximize the use of existing hazard information.
