GAO released on March 6, 2019, a report entitled High-Risk Series:  Substantial Efforts Needed to Achieve Greater Progress on High-Risk Areas.  GAO’s high-risk program identifies government operations with vulnerabilities to fraud, waste, abuse, and mismanagement, or in need of transformation to address economy, efficiency, or effectiveness challenges.  GAO’s report describes the status of high-risk areas and outlines actions necessary to assure further progress.  GAO states that in the two years since its last high-risk report, three areas, including “Transforming EPA’s Process for Assessing and Controlling Toxic Chemicals,” have regressed in their ratings against GAO’s criteria for removal from the High-Risk List.  GAO notes that since adding this area to its High-Risk List in 2009, it has made 12 recommendations to EPA related to the IRIS Program and TSCA.  According to GAO, while EPA has taken steps to manage chemicals that pose risks to human health and the environment, leadership and implementation challenges remain.  More information is available in B&C’s March 8, 2019, memorandum, “EPA’s Process for Assessing and Controlling Toxic Chemicals Remains on GAO’s High-Risk List.”

On February 20, 2019, during a cold, snow-filled winter day, the rugged staff of Bergeson & Campbell, P.C. (B&C®) as well as several hearty senior U.S. Environmental Protection Agency (EPA) officials got together over some steaming cups of coffee and discussed the upcoming fate of the Toxic Substances Control Act (TSCA) during a Bloomberg-hosted, B&C-developed webinar:  Chemical Policy Summit Series Part V: Chemical Regulation After the Mid-Terms: What We Can Expect to See in 2019

In attendance were:  The Honorable Alexandra Dapolito Dunn, the newly appointed Assistant Administrator of EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP); Jeffery T. Morris, Ph.D., Director, Office of Pollution Prevention and Toxics (OPPT); Rick P. Keigwin, Jr., Director of the Office of Pesticide Programs (OPP); Beau Greenwood, Executive Vice President, Government Affairs, CropLife America; Lynn L. Bergeson, Managing Partner of B&C; and James V. Aidala, Senior Government Affairs Consultant, B&C.  Ms. Dunn, Dr. Morris, and Mr. Keigwin described their priorities in the webinar.  Ms. Dunn stated 2019 “is going to be one of those buckle-your-seat-belt kind of years” in relation to getting everything done as required under TSCA.  Some of the takeaways from that webinar are listed below. 

TSCA Milestones:  2019 and Beyond

 

 

 

 

 

 

 

 

 

Risk Evaluations:

  • EPA must complete the first ten risk evaluations by December 2019, with a possible extension up to June 2020; EPA may need to take advantage of the extension;
  • By April 2019, EPA will need to release the “20 high- and 20 low-” priority candidate chemicals;
  • EPA released its first draft chemical risk evaluation -- Colour Index (C.I.) Pigment Violet 29 -- on which many comments were submitted.  EPA realized that this selection was challenging given certain data ownership issues and restrictions on those data occasioned by European Union’s (EU) Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation issues; therefore, this initial evaluation was not the best representation of how the other evaluations will be conducted (more information on the risk evaluation is available in our memo EPA Publishes First Draft TSCA Chemical Risk Evaluation);
  • EPA is using a new risk assessment program process called “Systematic Review” that has been used in non-risk assessment fields; EPA is the first agency to use this process.  EPA welcomes input on the process and stated that the National Academy of Sciences (NAS) will be reviewing this process as well;
  • In March 2019, EPA will release a proposed rule outlining how it will review and substantiate all Confidential Business Information (CBI) claims seeking to protect the specific chemical identities of substances on the confidential portion of the TSCA Inventory; and
  • EPA will be proposing its rule to regulate five persistent, bioaccumulative, and toxic chemicals by June 2019; EPA will be using a different approach than what is typically used for risk assessments.

Approving New Chemicals:

  • EPA intends to explore its process for new chemical review to be more predictable and to make reviews final within 90 days;
  • EPA will post “frequently asked questions” documents to help chemical manufacturers submit clearer applications online;
  • EPA is urging pre-submission meetings between premanufacture notice (PMN) submitters and EPA staff prior to submitting a PMN for a new product to reduce agency time spent clarifying omissions; and
  • EPA has pledged to make all PMNs, all health and safety studies, attachments, amendments and other associated information available in public dockets.

B&C’s other upcoming seminars and webinars are available here.  Some other resources of interest are B&C’s newly minted TSCA Tutor™ Modular Training Program which provides live in-person training at a company’s site, live online training, and pre-recorded webinar training modules -- all designed to offer expert, efficient, and essential TSCA training; as well as B&C’s All Things Chemical™ Podcasts, which provide intelligent, insightful conversation about everything related to industrial, pesticidal, and specialty chemicals and the law and business issues surrounding chemicals.

On January 28, 2019, the U.S. Environmental Protection Agency (EPA) published its Year in Review:  2018 (YIR).  The YIR lists the following accomplishments:

  • Issued major proposals, including the Affordable Clean Energy Rule, the Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule, and the new waters of the U.S. definition;
  • Provided greater regulatory certainty to states, tribes, localities, and the regulated community;
  • Streamlined the effectiveness and efficiency of EPA;
  • Launched cross-agency initiatives to improve risk communication on emerging contaminants and vulnerable populations;
  • Initiated multiple actions to reduce lead exposure, including releasing the Federal Lead Action Plan;
  • Improved enforcement compliance and assistance;
  • Held EPA’s first-ever Per- and Polyfluoroalkyl Substances (PFAS) National Leadership Summit and Inaugural Recycling Day Summit;
  • Led international environmental efforts, including first-ever articles to prevent and reduce marine litter; and
  • Ensured comprehensive and coordinated responses to multiple natural disasters.

The YIR provides the following “by the numbers” summary:

  • Regulatory Reform:  EPA issued 13 final deregulatory actions in 2018.  To date, under President Trump, EPA has issued 33 final major deregulatory actions, “saving Americans almost $2 billion”;
  • Air:  EPA reported that, during President Trump’s first year in office, greenhouse gas emissions from major industrial sources decreased by 2.7 percent;
  • Water:  By the end of 2018, EPA closed seven Water Infrastructure Finance and Innovation Act (WIFIA) loans totaling nearly $2 billion to help finance over $4 billion for water infrastructure projects and create up to 6,000 jobs;
  • Land:  EPA deleted all or part of 22 sites from Superfund’s National Priorities List in fiscal year (FY) 2018 -- “the largest number of deletions in one year since FY 2005”;
  • Chemicals:  After inheriting a “backlog” of 672 new chemical submissions pending review in January 2017, under President Trump, EPA “aggressively worked to improve the review of new chemical submissions and, as a result, eliminated the initial backlog and reduced the number of cases pending review to 475 submissions by August 2018.”  EPA completed 99.7 percent of the 2,199 pesticide registration actions on-time, and registered 23 new active ingredients and 147 new uses of existing pesticides, “providing new tools to growers to meet their pest management needs”;
  • Enforcement:  In FY 2018, EPA enforcement actions required the treatment, disposal, or elimination of 809 million pounds of pollutants and waste -- almost twice as much as FY 2017.  EPA also entered into the largest settlement in the history of its enforcement of the Risk Management Program with the responsible party spending $150 million on major safety improvements; and
  • Grants:  EPA awarded $4,451,520,905 in grants in FY 2018, including more than $63 million under the General Assistance Program, benefiting nearly all federally recognized tribes through awards to 500 tribal governments and approximately 25 intertribal consortia, $4.344 million in State and Tribal Assistance Grants, and 37 environmental education grants totaling $3,306,760 in 32 states to 13 colleges and universities, 23 stakeholder organizations, and one tribal community.

On November 29, 2019, the U.S. Environmental Protection Agency (EPA) announced that it has scheduled the first public meetings of the Toxic Substances Control Act (TSCA) Science Advisory Committee on Chemicals (SACC).  The first meeting, a preparatory virtual meeting, and will be held on January 8, 2019, from 2:00 p.m. to 4:00 p.m. (EST).  The second meeting, a four-day in-person meeting, will be held on January 29, 2019, from 1:00 p.m. (EST) to 5:30 p.m. and on January 30, 31, and February 1, 2019, from 9 a.m. to 5:30 p.m. (EST).  The official announcement is scheduled to be published in the Federal Register on November 30, 2018.  Further information, including the location of the in-person meeting and how to register, will be posted on EPA’s TSCA Scientific Peer Review Committees website.

The topic for this first series of meetings is the peer review of the draft risk evaluation for Colour Index (C.I.) Pigment Violet 29 and associated documents developed under EPA’s existing chemical substance process under TSCA.  EPA states that the two-hour preparatory virtual meeting on January 8, 2019, will consider the scope and clarity of the draft charge questions for this peer review -- included with EPA’s Transmission of Background Materials and Charge to the Panel for the TSCA SACC Reviewing the Draft Risk Evaluation for C.I. Pigment Violet 29 (Attachment 23).  The 4-day, in-person, public meeting will be comprised of the peer review panel deliberations and a general TSCA orientation for the TSCA SACC.  A portion of the in-person meeting will be closed to the public, however, for the discussion of information claimed as confidential business information (CBI).

During these upcoming meetings, EPA states that the public is invited to provide oral comments for the peer review on the draft risk evaluation for C.I. Pigment Violet 29 and related documents; comments submitted by January 14, 2019, on the draft risk evaluation will be provided to the peer review panel members before the in-person meeting.  Comments on the draft charge questions will be accepted prior to and during the 2-hour preparatory virtual meeting (but preferably by January 7, 2019); the TSCA SACC peer review panel will consider these comments during their discussions. 

More information on the draft risk evaluation for C.I. Pigment Violet 29 is available in our memorandum EPA Publishes First Draft TSCA Chemical Risk Evaluation.

The U.S. Environmental Protection Agency (EPA) published a Federal Register notice on November 15, 2018, announcing the availability of and seeking public comment on the first draft chemical risk evaluation under the Toxic Substances Control Act (TSCA), as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act (Lautenberg).  The draft risk evaluation for Colour Index (C.I.) Pigment Violet 29 is intended to determine whether C.I. Pigment Violet 29 presents an unreasonable risk to health or the environment under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation.  According to the notice, EPA is also submitting these same documents to the TSCA Science Advisory Committee on Chemicals (SACC) to peer review the draft risk evaluation.  EPA intends to publish a separate Federal Register notice containing the peer review meeting details.  Comments on the draft risk evaluation are due January 14, 2019.  EPA will provide all comments submitted on the draft risk evaluation to the TSCA SACC peer review panel, which will have the opportunity to consider the comments during its discussions.  More information is available in the full memorandum.

On October 17, 2018, the Trump Administration published its Unified Agenda of Regulatory and Deregulatory Actions (Regulatory Agenda).  There are many interesting entries, some of which are flagged here.

Not surprisingly, the U.S. Environmental Protection Agency (EPA) listed implementing Toxic Substances Control Act (TSCA) amendments to enhance public health and chemical safety as one of its top priorities.  According to EPA, the amendments to TSCA that were enacted in June 2016 require EPA “to evaluate existing chemicals on the basis of the health risks they pose -- including risks to vulnerable groups and to workers who may use chemicals daily as part of their jobs.”  If unreasonable risks are found, EPA must then take steps to eliminate these risks but, “during the risk management phase, EPA must balance the risk management decision with potential disruption based on compliance to the national economy, national security, or critical infrastructure.”  The following TSCA items were included. 

The rules in the proposed rule stage are:

  • Microorganisms: General Exemptions From Reporting Requirements; Revisions of Recipient Organisms Eligible for Tier I and Tier II Exemptions, 2070-AJ65.  The Regulatory Agenda states that EPA is still developing a revised proposal that will address concerns raised by commenters in response to its preliminary determination that certain strains of Trichoderma reesei and Bacillus amyloliquefaciens will not present an unreasonable risk of injury to health or the environment when used as a recipient microorganism, provided that certain criteria for the introduced genetic material and the physical containment conditions are met.  EPA is also considering expanding the earlier proposal to prohibit the inclusion of antibiotic resistance genes in the introduced genetic material in microorganisms qualifying for the TSCA Section 5(h)(4) exemption.  EPA was scheduled to issue a proposed rule by October 2018.
  • Long-Chain Perfluoroalkyl Carboxylate (LCPFAC) and Perfluoroalkyl Sulfonate Chemical Substances; Significant New Use Rule (SNUR), 2070-AJ99.  The Regulatory Agenda states that EPA is developing a supplemental proposal for part of a SNUR under TSCA Section 5(a)(2) for LCPFAC chemical substances to make inapplicable the exemption for persons who import a subset of LCPFAC chemical substances as part of certain articles.  This rule was scheduled to be proposed by October 2018 and issued in final by November 2019.  EPA’s initial proposed rule was issued on January 21, 2015.
  • Procedural Rule:  Review of Confidential Business Information (CBI) Claims for the Identity of Chemicals on the TSCA Inventory -- Amended TSCA Section 8(b)(4)(C), 2070-AK21.  The Regulatory Agenda states that EPA is developing a proposed rule that establishes a plan to review all claims to protect the specific chemical identities of chemical substances on the confidential portion of the active TSCA Inventory.  EPA is scheduled to issue the proposed rule by January 2019 and the final rule by December 2019, as TSCA directs a final rule to be issued by December 16, 2019
  • TSCA Chemical Data Reporting Revisions and Small Manufacturer Definition Update for Reporting and Recordkeeping Requirements Under TSCA Section 8(a), 2070-AK33.  The Regulatory Agenda states that before the next Chemical Data Reporting (CDR) period of 2020, EPA intends to revise the reporting requirements to better align with new statutory requirements resulting from TSCA, as amended, to address submitters' feedback following the 2016 submission period, and may consider reporting requirements for inorganic byproducts.  EPA is also proposing amendments to the size standards for small manufacturers, which impacts certain reporting and recordkeeping requirements for TSCA Section 8(a) rules, including CDR.  EPA is scheduled to issue the proposed rule by December 2018 and the final rule by October 2019.
  • Regulation of Persistent, Bioaccumulative, and Toxic Chemicals Under TSCA Section 6(h), 2070-AK34.  The Regulatory Agenda states that EPA is developing a proposed rule to implement TSCA Section 6(h), as amended, which directs EPA to issue regulations for certain persistent, bioaccumulative, and toxic (PBT) chemical substances that were identified in the 2014 update of the TSCA Work Plan.  TSCA directs these regulations to be proposed by June 22, 2019, and issued in final form no later than 18 months after proposal.  According to the Regulatory Agenda, EPA will issue a proposed rule by June 2019.
  • Technical Issues; Formaldehyde Emission Standards for Composite Wood Products, 2070-AK47.  EPA is proposing to amend the regulations promulgated in a final rule published on December 12, 2016, concerning formaldehyde emission standards for composite wood products, specifically to address certain technical issues and further align the final rule requirements with the California Air Resources Board (CARB) Airborne Toxic Control Measures (ATCM) Phase II program.  EPA issued the proposed rule on November 1, 2018, in the Federal Register; comments are due by December 3, 2018.  EPA expects to issue a final rule by March 2019.  

The rules in the final rule stage are:

  • Review of Dust-Lead Hazard Standards and the Definition of Lead-Based Paint, 2070-AJ82.  EPA issued a proposed rule on July 2, 2018, that would lower the current dust-lead hazard standards (DLHS) from 40 mg/ft2 and 250 mg/ft2 to 10 mg/ft2 and 100 mg/ft2 on floors and window sills, respectively, per a final decision of the U.S. Court of Appeals for the Ninth Circuit.  The Regulatory Agenda states that while EPA has proposed standards of 10 mg/ft2 and 100 mg/ft2 for floors and window sills respectively, EPA encouraged public comment on the full range of candidate standards analyzed as alternatives to the proposal, including the option not to change the current standard or to reduce the floor dust standard but leave the sill dust standard unchanged, since reducing floor dust lead has the greatest impact on children's health.  EPA is scheduled to issue the final rule by June 2019.  More information on the proposed rule is available in our memorandum “Recent Federal Developments -- July 2018.”
  • SNUR for Toluene Diisocyanates (TDI) and Related Compounds, 2070-AJ91.  The Regulatory Agenda states that EPA is preparing the final version of a proposed SNUR issued on January 15, 2015, under TSCA Section 5(a)(2) for 2,4-toluene diisocyanate, 2,6-toluene diisocyanate, toluene diisocyanate unspecified isomers, and related compounds; and that there are no changes in the chemicals subject to the SNUR between the proposed and final rule.  EPA is scheduled to issue the final rule in November 2018.
  • Significant New Uses of Chemical Substances; Updates to the Hazard Communication Program and Regulatory Framework; Minor Amendments to Reporting Requirements for Premanufacture Notices, 2070-AJ94.  On July 28, 2016, EPA issued a rule proposing changes to the applicable significant new uses of chemical substances regulations at 40 C.F.R. Part 721 to align EPA's regulations, where possible, with the final revisions to the U.S. Occupational Safety and Health Administration (OSHA) Hazard Communications Standard.  The Regulatory Agenda states that EPA is reviewing the comments received and is planning to issue a final rule in February 2019.
  • Certain Nonylphenols and Nonylphenol Ethoxylates; SNUR, 2070-AJ96.  The Regulatory Agenda states that EPA is reviewing the comments received on the proposed SNUR issued on October 1, 2014, for certain chemical substances commonly known as nonylphenols (NP) and nonylphenol ethoxylates (NPE) and is planning to issue a final rule in September 2019.  More information on the proposed SNUR is available in our memorandum “EPA Proposes SNUR for Nonylphenols and Nonylphenol Ethoxylates.”
  • Methylene Chloride; Rulemaking Under TSCA Section 6(a), 2070-AK07.  The Regulatory Agenda states that EPA is scheduled to issue the final rule prohibiting the consumer and commercial paint stripping uses for methylene chloride by December 2018.  In a press release issued on May 10, 2018, EPA stated that it will not re-evaluate the paint stripping uses of methylene chloride and will rely on its previous risk assessments.  See our memorandum “EPA Will Send Final Methylene Chloride Rule to OMB ‘Shortly’” for more information on the proposed rule. 
  • Asbestos; SNUR, 2070-AK45.  The Regulatory Agenda states that EPA’s proposed SNUR under TSCA Section 5(a)(2) for certain uses of asbestos that are no longer in use in the United States is scheduled to be issued in final by January 2019.  The proposed SNUR was issued on June 11, 2018, and the comment period ended on August 10, 2018.  More information on the proposed rule is available in our memorandum “Monthly Update for June 2018.”

The following Long-Term Action was also listed:

  • N-Methylpyrrolidone (NMP); Regulation of Certain Uses Under TSCA Section 6(a), RIN 2070-AK46.  The Regulatory Agenda states that EPA’s two co-proposals for NMP that were proposed on January 19, 2017 (as part of RIN 2070-AK07), will be issued in final with a future date “To Be Determined.”  The first co-proposal would prohibit the manufacture, processing, and distribution in commerce of NMP for all consumer and most commercial paint and coating removal and the use of NMP for most commercial paint and coating removal.  The second co-proposal would require commercial users of NMP for paint and coating removal to establish a worker protection program and not use paint and coating removal products that contain greater than 35 percent NMP by weight, with certain exceptions; and require processors of products containing NMP for paint and coating removal to reformulate products such that they do not exceed 35 percent NMP by weight, to identify gloves that provide effective protection for the formulation, and to provide warnings and instructions on any paint and coating removal products containing NMP.  For more information on the proposed rule, please see our memorandum "Monthly Update for February 2017."

On October 17, 2018, the U.S. Environmental Protection Agency (EPA) issued its final fees rule under the Toxic Substances Control Act (TSCA) in the Federal Register.  83 Fed. Reg. 52694.  The final rule largely tracks the proposed rule.  EPA is establishing fees applicable to any person required to submit information to EPA; or a notice, including an exemption or other information, to be reviewed by EPA; or who manufactures (including imports) a chemical substance that is the subject of a risk evaluation.  This final rulemaking describes the final TSCA fees and fee categories for fiscal years 2019, 2020, and 2021, and explains the methodology by which the final TSCA fees were determined.  It identifies some factors and considerations for determining fees for subsequent fiscal years; and includes amendments to existing fee regulations governing the review of premanufacture notices, exemption applications and notices, and significant new use notices. As required in TSCA, EPA is also establishing standards for determining which persons qualify as “small business concerns” and thus would be subject to lower fee payments.  Small businesses will be eligible to receive a substantial discount of approximately 80 percent on their fees.  EPA will host a series of webinars focusing on making TSCA submissions and paying fees under the final rule.  The first webinar was held on October 10, 2018.  The other two webinars will be held on October 24, 2018, from 1:00 p.m. to 2:30 p.m. (EDT) and on November 7, 2018, from 1:00 p.m. to 2:30 p.m. (EDT).  Our memorandum provides an overview of the final rule with specific information about final fee amounts and timing and a commentary.  The final rule is effective on October 18, 2018.

The U.S. Environmental Protection Agency (EPA) issued on October 16, 2018, a proposed rule that would establish significant new use rules (SNUR) under the Toxic Substances Control Act (TSCA) for 13 chemical substances that are the subject of premanufacture notices (PMN).  83 Fed. Reg. 52179.  The proposed rule is significant.  Unlike other recent SNURs (i.e., those enacted since entry into force of amended TSCA), the 13 chemical substances are not also subject to consent orders.  For this reason, the preamble contains novel language to address the new circumstances and legal issues encountered in the proposed rule.  The proposed SNURs would require persons who intend to manufacture (defined by statute to include import) or process any of the 13 chemical substances for an activity that is designated as a significant new use to notify EPA at least 90 days before commencing that activity.  The required notification will initiate EPA’s evaluation of the intended use within the applicable review period.  Persons may not commence the manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required with that determination.  Comments on the proposed SNURs are due November 15, 2018.

Please see the full memorandum for more information on the proposed rule and an illuminating commentary.

On October 5, 2018, the U.S. Environmental Protection Agency (EPA) issued the general approaches that the Office of Pollution Prevention and Toxics (OPPT) may use to identify potential candidate chemicals for prioritization under TSCA.  83 Fed. Reg. 50366.  EPA notes that it will seek public comment on the approach document and on which chemicals should be identified as potential candidates for the initial 20 high-priority and 20 low-priority chemicals that must be identified pursuant to TSCA Section 6(b)(2)(B).  Comments are due by November 15, 2018

The document, A Working Approach for Identifying Potential Candidate Chemicals for Prioritization, lays out EPA’s thinking regarding a near-term approach for identifying potential chemicals for prioritization, the initial step in evaluating the safety of existing chemicals under TSCA.  The approach document also includes a longer-term risk-based strategy for managing the larger TSCA chemical landscape that, according to the portion of the TSCA Chemical Substance Inventory (Inventory) that includes the substances designated as active (TSCA Active Inventory), is expected to include over 38,000 chemicals reported as “active” under the TSCA Inventory Notification (Active-Inactive) Requirements final rule.  More information is available in our memorandum “EPA Releases Working Approach for Identifying Potential Candidate Chemicals for Prioritization under TSCA.”
