Significant New Use Rules on Certain 
Chemical Substances 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : EPA is proposing significant 
new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 27 chemical substances which were the subject of premanufacture notices (PMNs). The chemical substances are subject to Orders issued by EPA pursuant to section 5(e) of TSCA. This action would require persons who intend to manufacture (defined by statute to include import) or process any of these 27 chemical substances for an activity that is designated as a significant new use by these rules to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA’s evaluation of the intended use within the applicable review period. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notification, and has taken such actions as are required with that determination. In addition to this notice of proposed rulemaking, EPA is issuing the action as a direct final rule elsewhere in this issue of the Federal Register.

World Trade Center Health Program; 
Petition 019—Irritable Bowel Syndrome; Finding of Insufficient Evidence 
AGENCY : Centers for Disease Control and 
Prevention, HHS. 
ACTION : Denial of petition for addition of 
a health condition. 
SUMMARY : On May 17, 2018, the 
Administrator of the World Trade Center (WTC) Health Program received a petition (Petition 019) to add irritable bowel syndrome (IBS) to the List of WTC-Related Health Conditions (List). Upon reviewing the scientific and medical literature, including information provided by the petitioner, the Administrator has determined that the available evidence does not have the potential to provide a basis for a decision on whether to add IBS to the List. The Administrator also finds that insufficient evidence exists to request a recommendation of the WTC Health Program Scientific/Technical Advisory Committee (STAC), to publish a proposed rule, or to publish a determination not to publish a proposed rule. 
DATES : The Administrator of the WTC 
Health Program is denying this petition for the addition of a health condition as of August 17, 2018. 
ADDRESSES : Visit the WTC Health 
Program website at https://www.cdc.gov/wtc/received.html to 
review Petition 019.
