particulate matter (PM2.5) national ambient air quality

erroneously

omitting the technical support document (TSD) in the docket. This 
proposed rule corrects this omission and provides notice of the 
availability of the TSD which supports EPA's analysis. All comments 
received on or before July 24, 2017 will be entered into the public 
record and considered by EPA before taking final action on the proposed 
rule. Comments submitted between the close of the original comment 
period and the re-opening of this comment period will be accepted and 
considered.

OAR-2017-0152 at http://www.regulations.gov, or via email to

follow the online instructions for submitting comments. Once submitted, 
comments cannot be edited or removed from Regulations.gov. For either 
manner of submission, EPA may publish any comment received to its 
public docket. Do not submit electronically any information you 
consider to be confidential business information (CBI) or other 
information whose disclosure is restricted by statute. Multimedia 
submissions (audio, video, etc.) must be accompanied by a written 
comment. The written comment is considered the official comment and 
should include discussion of all points you wish to make. EPA will 
generally not consider comments or comment contents located outside of 
the primary submission (i.e. on the web, cloud, or other file sharing 
system). For additional submission methods, please contact the person
