SUPPLEMENTARY INFORMATION:

In response to requests for an extension, we are extending the public comment period for the Heavy-Duty Phase 2 Notice of Proposed Rulemaking (80 FR 40139, July 13, 2015; also available in Docket Nos. EPA-HQ-OAR-2014-0827 and NHTSA-2014-0132) to October 1, 2015. As NHTSA published (to Docket No. NHTSA-2014-0074) an accompanying DEIS for NHTSA's proposed rule, we are also extending the comment period for that document to October 1, 2015. This extension will provide the public additional time to provide comment on the proposed rules and DEIS. Both the proposed rules and the DEIS are available at www.regulations.gov. Instructions for submitting comments to either EPA or NHTSA are described in the Public Participation section of the Notice of Proposed Rulemaking.

In this joint proposal, there are many issues common to both EPA's and NHTSA's proposals. For the convenience of all parties, comments submitted to the EPA docket will be considered comments submitted to the NHTSA docket, and vice versa. An exception is that comments submitted to the NHTSA docket on NHTSA's (DEIS) will not be considered submitted to the EPA docket. Therefore, the public only needs to submit comments to either one of the two agency dockets, although they may submit comments to both if they so choose. Comments that are submitted for consideration by one agency should be identified as such, and comments that are submitted for consideration by both agencies should be identified as such. Absent such identification, each agency will exercise its best judgment to determine whether a comment is submitted on its proposal.
