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.

    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
