EPA Publishes Final Reporting Requirements for TSCA Mercury Inventory

/in

On June 27, 2018, the Environmental Protection Agency (EPA) published the final “Reporting Requirements for the TSCA Mercury Inventory” Rule. As required under section 8(b)(10)(D) of the Toxic Substances Control Act (TSCA), EPA finalized reporting requirements for regulated entities to provide information to assist in the preparation of an “inventory of mercury supply, use, and trade in the United States.”

The requirements apply to any person who manufactures (including imports) mercury or mercury-added products, or otherwise intentionally uses mercury in a manufacturing process. The reporting requirements apply to “mercury” as both “elemental mercury” and “a mercury compound.” EPA provides a list of these compounds in the final rule. Reporting requirements vary based on whether the entity is manufacturing mercury, manufacturing a mercury added product, or intentionally using mercury in a manufacturing process, other than the manufacture of a mercury compound or a mercury-added product. EPA will collect data through the Mercury Electronic Reporting (MER) application of its CDX system.

Based on the inventory of information collected, the Agency is directed to “identify any manufacturing processes or products that intentionally add mercury; and . . . recommend actions, including proposed revisions of Federal law or regulations, to achieve further reductions in mercury use.” EPA stated in the final rule that it is not making such identifications or recommendations at this time.

EPA will use data from the 2018 reporting year for the 2020 mercury inventory. The 2018 reporting year is from January 1, 2018, to December 31, 2018, and the submission deadline for the 2018 reporting year is July 1, 2019.

Sherwin-Williams to Remove Paint-Removal Products Containing Methylene Chloride

/in

Sherwin-Williams is phasing out the use of paint-removal products containing methylene chloride by the end of this year. Both Lowe’s and Home Depot have also announced they will phase out paint removal products that contain methylene chloride. These actions are likely a response to EPA’s forthcoming rulemaking on the substance.

In January, 2017, EPA proposed prohibiting the consumer and commercial paint stripping used for methylene chloride. On May 10, 2018, EPA announced it was working on sending the finalized rulemaking to Office of Management and Budget “shortly.”

Systematic Review for TSCA Risk Evaluations

/in ,

On May 31, 2018 EPA released  Application of Systematic Review in TSCA Risk Evaluations.  The document presents a detailed description of EPA’s approach to the Risk Evaluations required by the Lautenberg amendments to TSCA.

The announcement by the Office of Pollution Prevention and Toxics (OPPT) explains that “[it] will guide EPA’s selection and review of studies in addition to providing the public with continued transparency regarding how the Agency plans to evaluate scientific information.”  In the document OPPT explains that the Agency intends to apply systematic review principles in the development of the risk evaluations required by the amended statute. The Application of Systematic Review in TSCA Risk Evaluations will serve as internal guidance for this process.  The document describes OPPT’s plan for identifying, evaluating and integrating evidence for the TSCA risk evaluation process.

The document includes chapters on scoping and problem formulation, integration of systematic review principles into TSCA risk evaluations, and appendices on strategy for assessing the quality of data supporting TSCA risk evaluations and data quality criteria for each of the categories of information considered in the evaluation (e.g., physical/chemical property data, occupational exposure and release data).  The Agency notes that this document is not necessarily applicable to risk assessments developed to support other EPA’s statutes or programs.  EPA invites the public to provide input on this document at www.regulations.gov, docket# EPA-HQ-OPPT-2018-0210.

For the risk evaluations, OPPT will first conduct scoping and problem formulation to develop an analytical framework.   Problem formulation will describe the exposure pathways, receptors and health endpoints that OPPT expects to consider in the risk evaluations.

The Agency will use “systematic review“ for problem formulation and the other stages of the risk evaluation process.  The Application of Systematic Review in TSCA Risk Evaluations explains that the risk evaluation process will rely on the National Academy of Sciences, Institute of Medicine’s definition of systematic review:  “a scientific investigation that focuses on a specific question and uses explicit, pre-specified scientific methods to identify, select, assess, and summarize the findings of similar but separate studies.”  OPPT reports that key elements of systematic review include:

  • A clearly stated set of objectives defining the research question,
  • Developing a protocol that describes the specific criteria and approaches that will be used throughout the process,
  • Applying the search strategy in a literature search,
  • Selecting the relevant papers using predefined criteria,
  • Assessing the quality of the studies using predefined criteria,
  • Analyzing and synthesizing the data using the predefined methodology, and
  • Interpreting the results and presenting a summary of findings.

Following problem formulation, OPPT will develop a protocol to specify the criteria, methods for data collection, data evaluation and data integration.

Data will be collected under a defined literature search strategy designed to collect information to evaluate the full life cycle of the chemical substance including exposure, human health hazard, and environmental hazard.  OPPT will use a comprehensive chemical-specific literature search of the open literature to identify relevant data.  OPPT will also use data that are submitted by the public and peer reviewers.  In addition, OPPT will search its internal databases for relevant data submitted under TSCA.  The Agency notes that data submitted under TSCA will be used in the risk evaluation whether or not they are claimed as confidential business information (CBI).  However, CBI data will be used in a manner that protects the confidentiality of the information.

Factors for inclusion in the evaluation include whether the data contain information on: 

  • Environmental fate, transport, partitioning and degradation behavior across environmental media of interest,
  • Environmental exposure of ecological receptors to the chemical substance and/or its degradation products and metabolites,
  • Environmental exposure of human receptors to the substance and/or its degradation products and metabolites,
  • Scenarios resulting in releases of the substance into the environment that would expose ecological or human receptors,
  • Quantitative estimates of worker exposures and of environmental releases from occupational settings for the substance, and
  • Human health and environmental hazards.

OPPT explains that the evaluation stage will assess the quality of individual studies.   For this process the Agency will use the criteria identified in the data quality criteria appendices to the Application of Systematic Review in TSCA Risk Evaluations.  The appendices specify criteria for evaluating data on:

  • Physical and chemical properties,
  • Occupational exposure and release,
  • Fate,
  • Consumer, general population, and environmental exposure,
  • Ecological hazards,
  • Animal and in vitro toxicity, and
  • Epidemiology.

The data will then be integrated to evaluate and synthesize multiple evidence streams.  Data integration includes analysis and synthesis of the evidence and development of weight of evidence conclusions.  As part of this process OPPT will document any underlying assumptions that are used to support the risk evaluation.

TSCA requires that EPA make decisions about these data based on the weight of the scientific evidence.  OPPT reports that under TSCA, the weight of the scientific evidence is defined as “a systematic review method, applied in a manner suited to the nature of the evidence or decision, that uses a pre-established protocol to comprehensively, objectively, transparently, and consistently identify and evaluate each stream of evidence, including strengths, limitations, and relevance of each study and to integrate evidence as necessary and appropriate based upon strengths, limitations, and relevance.”   This approach presents the significant issues, strengths, and limitations of the data and the uncertainties that require consideration, in addition to highlighting the major points of interpretation.

OPPT explains that the last step of the systematic review process will be to develop a summary of findings.  The findings summarize the evidence, describe the methods used to weigh evidence, and articulate the basis for the conclusion(s), recommendation(s), and any uncertainties.  Both exposure assessment and hazard assessment will be discussed.

TSCA Fees Rule — Release of Supplemental Information and Comment Period Extension

/in

On April 24, 2018, EPA released for public comment a supplemental analysis on the definitions of small business size and their effect on Toxic Substances Control Act (TSCA) user fee collection. In the proposed fees rule EPA released in February, small businesses can quality for reduced fee amounts. For the supplemental analysis, EPA requested comment on:

  • Whether an employee-based size standard (how many people are working there) would be more appropriate than a revenue-based size standard (how much revenue comes in), and what that employee level should be (note: the revenue level standard is already in the proposed rule);
  • Whether either size standard should vary from industry to industry for any reason;
  • What other factors and data sources the Agency should consider, besides inflation, when developing the size standard; and
  • What should the new TSCA section 5 fee amounts be if EPA changes the size standard?

EPA is also extending the comment period for the proposed TSCA fees rule until May 24, 2018. This is meant to give interested parties more time to comment on both the rule and the supplemental analysis.

EPA Issues Draft TSCA Inventory With “Active” Substance Designations

/in

Under the Environmental Protection Agency’s (EPA) Toxic Substances Control Act (TSCA) Inventory Reset Rule, manufacturers and importers were required to report all chemical substances that were active in commerce in the ten year “look-back period” ending June 21, 2016. Based on the information it received, the EPA published a draft version of the TSCA Inventory that contains 38,304 substances with “active” designations.

The draft Inventory designates as active those substances:

  • Substances notified under the 2012 and 2016 Chemical Data Reporting (CDR) rule;
  • Those substances EPA received notices of commencement (NOCs) since June 21, 2006; and
  • Substances reported via notices of activity (NOAs) before the February 7, 2018 Inventory Reset reporting deadline.

Substances listed as “active” in the draft Inventory include 30,972 on the public inventory and 7,332 on the confidential inventory. There are approximately 48,000 substances that have not been reported as active.

“Active” designations may grow in the coming months. The Inventory Reset Rule allows processors to report any substances that did not get reported as active by manufacturers or importers until October 5, 2018. In addition EPA has established a process to “activate” substances that are designated inactive.

EPA Releases Draft Guidance on TSCA CBI Disclosures and Requests Comments

/in

On March 13, 2018, EPA released three draft guidance documents for public comment clarifying the circumstances under which EPA may disclose TSCA confidential business information (CBI) with an expanded set of people. Comments will be accepted until April 16, 2018.

Amendments to the Toxic Substances Control Act (TSCA) expanded the categories of people who may now access information claimed as CBI under TSCA. Information that a business claims as CBI under TSCA is protected from disclosure until the business withdraws the CBI claim, until the CBI claim expires, until EPA determines that the claim is not entitled to confidential treatment, or as authorized under TSCA and EPA regulations.

The draft guidance documents are:

EPA Publishes TSCA User Fee Proposed Rule

/in ,

Under the proposed TSCA User Fee Rule, submitters would pay $16,000 for each PMN. This was announced on February 8, 2018, when the U.S. Environmental Protection Agency (EPA) announced that EPA Administrator Scott Pruitt signed a proposed rule regarding user fees for the administration of the Toxic Substances Control Act (TSCA). The current fee for a PMN submission is $2,500. EPA estimates the average cost of a PMN for processing, reviewing, making determinations, and taking any regulatory action such as with a SNUR or an order is approximately $55,000. Fees would also apply to submissions related to risk evaluation and EPA mandated testing of chemical substances and mixtures.

The proposed rule was published on February 27, 2018. Comments on the rule must be received on or before April 27, 2018 (Docket Number EPA-HQ-OPPT-2016-0401).

Amended TSCA provides EPA the authority to charge fees to 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.” These fees are to be used for “developing risk evaluations for existing chemicals; collecting and reviewing toxicity and exposure data and other information; reviewing Confidential Business Information (CBI); and, making determinations in a timely and transparent manner with respect to the safety of new chemicals before they enter the marketplace.” However, EPA is not proposing to assess greater fees for submissions containing CBI claims.

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) under section 4;
  • Submit a PMN, SNUR, LVE or other notification under section 5); or
  • Manufacture or process a chemical substance that is subject to a risk evaluation under section 6, including a risk evaluation conducted at the request of a manufacturer.

Beginning in fiscal year (FY) 2019 , EPA will be required to adjust fees every three years to reflect inflation and ensure that fees are sufficient to collect 25 percent of the costs to EPA in administering TSCA sections 4, 5, 6, and 14, up to $25 million. The proposed rule provides a description of proposed TSCA fees and fee categories for FYs 2019, 2020, and 2021, and explains the basis for its proposal.

TSCA Inventory Reset Deadline Is Approaching

/in ,

The TSCA Inventory Reset process is designed to identify which listed chemical substances are and which are not actively used in commerce. Substances identified as “in commerce” will be placed on the “Active Inventory.” Substances not currently in commerce will be placed on the “Inactive Inventory.” Companies will not be able to lawfully manufacture, import, or process any chemical substance on the “Inactive Inventory” without first notifying the substance to EPA.

The rule establishes “retrospective” (as well as “forward-looking”) reporting requirements. During the initial retrospective reporting period, companies must report on each Inventory-listed substance that they manufactured or imported for a non-exempt purpose during the ten-year look back period (June 21, 2006 and June 21, 2016). The deadline for this reporting period is February 7, 2018.

A subsequent reporting period, beginning April 9, 2018, is designated for reporting by processors. Companies may report substances that they processed during the ten-year look back period if the substances are not already on EPA’s Active Inventory or Interim Active Inventory.

EPA Releases the 2018 Plan for Chemical Risk Evaluations under TSCA

/in , , ,

As required under the Frank R. Lautenberg Chemical Safety for the 21st Century Act, EPA has released its annual plan for chemical risk evaluations. The annual plan identifies the next steps for the first 10 chemical reviews currently underway, and describes EPA’s work in 2018 to prepare for future risk evaluations.

EPA was required to initiate ten risk evaluations in 2016, and is required to initiate at least 20 more within 3 years after enactment of the Lautenberg Act, or by December 2019. EPA designated the first ten chemical substances on December 19, 2016. By the end of 2018, the EPA will initiate prioritization for 40 chemicals – at least 20 Low-Priority and 20 High-Priority candidates. By December 22, 2019, EPA will designate 20 substances as Low-Priority and initiated risk evaluations on 20 High-Priority substances.

In order to support these risk evaluations and other key aspects of TSCA implementation, EPA stated that it will be proposing a draft TSCA Fees Rule in early 2018, which will provide estimates of the resources required to undertake risk evaluations.

EPA Semiannual Regulatory Agenda Postpones Regulation of Methylene Chloride, NMP, and TCE

/in ,

The EPA Fall 2017 Regulatory Agenda defers Agency action on three chemicals for which the proposed rules had indicated bans would be forthcoming:

  • Methylene chloride in paint strippers,
  • N-methylpyrrolidone (NMP) in paint strippers, and
  • Trichloroethylene (TCE) as a spot cleaner in dry-cleaning and as a degreasing agent.

The rulemakings are listed as “long-term actions” and will be issued “to be determined” in the Semiannual Regulatory Agenda.   EPA has not explained the reason for the deferrals.   Proposed regulations for methylene chloride and NMP were issued in January 2017.  Further information on EPA’s past actions regarding methylene chloride can be found here. Further information on EPA’s past actions regarding NMP can be found here.  Proposed regulations for TCE were issued in December 2016 and January 2017.  Further information on EPA’s past actions regarding the substance can be found here.

The rulemakings were developed under section 6(a) of the Toxic Substances Control Act (TSCA).  They address uses of the chemicals identified to be of concern in risk assessments published prior to the Lautenberg amendments to the statute.  In addition to the proposed rules on these uses of concern, all three chemicals are also are among the first substances selected for risk evaluation under the Lautenberg amendments.  EPA is required to complete each of those risk evaluation within 3 years of its initiation.  (The amendments also allow the Agency two years after each risk evaluation is published to issue final rules restricting the uses of chemicals that present an unreasonable risk of injury to health or the environment.)  A larger set of uses than those identified above will be considered in the forthcoming risk evaluations.  However, EPA has been sued over the final rule for the risk evaluation process.  One issue challenged in that litigation is the scope of uses that will be addressed by the process.  That litigation is ongoing.
