On May 23, 2017, the U.S. Environmental Protection Agency (EPA) submitted its final rulemaking on the Procedures for Prioritization of Chemicals for Risk Evaluation Under the Toxic Substances Control Act (TSCA) to the Office of Management and Budget (OMB) for review and approval. In the proposed rule, EPA describes the processes for identifying potential candidates for prioritization, selecting a candidate, screening that candidate against certain criteria, formally initiating the prioritization process, providing opportunities for public comment, and proposing and preparing final priority designations. EPA also incorporates all of the elements required by new TSCA, but also supplements those requirements with additional criteria it expects to consider, some clarifications intended to provide greater transparency, and additional procedural steps to ensure effective implementation. Comments were due March 20, 2017; 70 comments were filed. Pursuant to new TSCA, EPA must publish the final rule in the Federal Register by June 22, 2017.
More information on the rule as proposed is available in our memorandum EPA Proposes Procedures to Prioritize Chemicals for Risk Evaluation under TSCA.

On February 9, 2017, the U.S. Environmental Protection Agency (EPA) issued its 2017 Annual Report on Risk Evaluations. Per Section 26(n)(2) of the amended Toxic Substances Control Act (TSCA), EPA is directed to publish an annual plan at the beginning of each calendar year identifying the chemical substances that will undergo risk evaluations during that year – both risk evaluations that will be initiated and that will be completed -- the resources necessary for completion, and the status and schedule for ongoing evaluations.
Per amended TSCA Section 6(b)(4), on December 19, 2016, EPA designated ten chemical substances for evaluation to determine whether they presented an unreasonable risk of injury to health or the environment. Those chemicals are:
- 1, 4 Dioxane;
- Methylene Chloride;
- Pigment Violet 29;
- Carbon Tetrachloride;
- Cyclic Aliphatic Bromide Cluster (HBCD); and
The report provides an update pertaining to the risk evaluations of these ten chemicals. Risk evaluations on these chemicals have already begun, and EPA anticipates issuing a scoping document for each of them by June 19, 2017. The scoping document will include “the hazard(s), exposure(s), condition(s) of use, and the potentially exposed or susceptible subpopulation(s) the Administrator expects to consider in the evaluation.” EPA has established a docket for each of the ten chemicals and is holding a public meeting on February 14, 2017, to present information on the specific uses and conditions of use for the chemicals. EPA is currently accepting written comments and materials in the individual dockets until March 15, 2017.
Under Section 6(4)(G) of TSCA, EPA is required to complete these risk evaluations within three to three and a half years. EPA’s initial report to Congress issued on January 18, 2017, detailed the resources it needed for completion of the risk evaluations.
More information on EPA’s proposed processes for prioritizing and evaluating chemicals beyond these first ten is available in our memoranda EPA Proposes Procedures to Prioritize Chemicals for Risk Evaluation under TSCA and EPA Releases Proposed Chemical Risk Evaluation Process under New TSCA.

The U.S. Environmental Protection Agency (EPA) is scheduled to publish a proposed rule in the January 17, 2017, Federal Register that would establish a risk-based screening process and criteria that EPA will use to identify chemical substances as either High-Priority Substances for risk evaluation, or Low-Priority Substances for which risk evaluations are not warranted at the time. The pre-publication version of the proposed rule describes the processes for identifying potential candidates for prioritization, selecting a candidate, screening that candidate against certain criteria, formally initiating the prioritization process, providing opportunities for public comment, and proposing and finalizing designations of priority. EPA notes that prioritization is the initial step in a new process of existing chemical substance review and risk management activity established under recent amendments to the Toxic Substances Control Act (TSCA). Publication of the notice will begin a 60-day comment period. More information on the final rule will be available in our forthcoming memorandum, which will be available on our website under the key phrase TSCA.

On November 7, 2016, the Office of Management and Budget’s (OMB) Office of Information and Regulatory Affairs (OIRA) received a pre-publication proposed rule on Procedures for Prioritization of Chemicals for Risk Evaluation Under the Toxic Substances Control Act (TSCA) from the U.S. Environmental Protection Agency. Also referred to as the “Prioritization Process Rule,” this procedural rule will stablish EPA's process and criteria for identifying high priority chemicals for risk evaluation and low priority chemicals. As stated in our memorandum TSCA Reform: EPA Publishes First Year Implementation Plan, this rule is the first of three “Framework Action” rules that the Frank L. Lautenberg Chemical Safety for the 21st Century Act (new TSCA) has directed EPA to issue in final within one year of enactment, or by mid-June 2017. For all three of these rules, the interim milestone for the proposed rules is mid-December 2016; therefore, it is anticipated that the three other rules will soon be sent to OMB for review as well. The two others are:
- Risk Evaluation Process Rule: A Procedural rule to establish EPA's process for evaluating the risk of high priority chemicals; and
- Inventory Rule: Rule to require industry reporting of chemicals manufactured/processed in the previous ten years. Results will be used to designate active and inactive chemicals on the TSCA Inventory of existing chemicals.
There is a fourth Framework Action rule that new TSCA has directed EPA to issue as well, but it does not have a deadline for issuance in final; new TSCA only species the mid-June 2017 date as a goal:
- Fees Rule: EPA is authorized to collect fees to help defray the cost of implementing certain provisions and to fully defray the cost of industry-requested risk evaluations, but must put a rule in place to require fees. There is no deadline in the bill, but authority to require fees will be needed as soon as possible.
More information on the implementation of new TSCA is available in our TSCA Reform News & Information website and in our TSCA Reform memoranda.

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.
