II. Background

A. Letter Peer Review

Section 6(h) of the Toxics Substances Control Act (TSCA) directs EPA to issue regulations under 6(a) for certain Persistent Bioaccumulative and Toxic (PBT) chemical substances that were identified in EPA's TSCA Work Plan for Chemical Assessments: 2014 update. The chemicals that were ranked high or moderate for either persistence and bioaccumulation, are present on the TSCA 2014 workplan chemical list that are not metals, that do not have problem formulation completed, do not have a review under section 5, and do not have a consent agreement under section 4 are the following five chemicals: Decabromodiphenyl ethers (DECA); Hexachlorobutadiene (HCBD); Pentachlorothiophenol (PCTP); Phenol, isopropylated, phosphate (3:1) (PIP3/ITPP); and 2,4,6-Tris(tert-butyl) phenol (2, 4, 6 TRIS).

No risk evaluation is required for these PBT chemicals. EPA has drafted an Exposure and Use Assessment and a Human Health and Environmental Hazard Summary, in response to the TSCA section 6(h) requirements to summarize conclusions of toxicity and whether there is likely exposure to these PBT chemicals. These documents contain the following components:

  • Chemistry, physical-chemical properties and expected transport and partitioning.
  • Characterization of manufacture (including import), processing, uses and potential sources of exposure.
  • Summary of available monitoring data, concentrations and doses.
  • Characterization of trends in releases/exposures over time.
  • Summary of environmental hazard (written and tabular summaries).
  • Summary of human health hazard (written and tabular summaries).
  • Strategy for identifying environmental hazard summary information.
  • Strategy for identifying human health summary information.
  • Supplemental Files that identify how environmental information was searched, screened, and evaluated.

B. Public Preparatory Meeting

The Agency has organized letter peer reviews for the Exposure and Use Assessment and the Human Health and Environmental Hazard Summary. The June 25, 2018 preparatory meeting will be held by teleconference and webcast only. During the preparatory meeting, the individual letter peer reviewers will have the opportunity to comment on and ask questions regarding the scope and clarity of the draft charge questions. Subsequent to this preparatory meeting, final charge questions will be provided for use as the letter peer reviewers complete their individual reviews.

C. Letter Peer Review Documents

EPA's background papers, related supporting materials, and charge/questions for these letter peer reviews will be available in the public docket (EPA-HQ-OPPT-2018-0314) on June 18, 2018. In addition, the Agency may provide additional background documents and public comments as the materials become available. You may obtain electronic copies of these documents, and certain other related documents that might be available in the public docket at http://www.regulations.gov and on the TSCA Peer Review website at https://www.epa.gov/​tsca-peer-review.
