AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule; extension of comment period.

SUMMARY:

The Environmental Protection Agency (EPA) is extending the comment period for the proposed rule titled, “Revisions to Test Methods, Performance Specifications, and Testing Regulations for Air Emission Sources,” that was published in the Federal Register on September 8, 2015. The 60-day comment period in the proposed rule is scheduled to end on November 9, 2015. The extended comment period will close on December 9, 2015. The EPA recently added a technical justification to the docket for the revision in the proposed rule regarding Subpart JJJJ of Part 60 (Standards of Performance for Stationary Spark Ignition Internal Combustion Engines). We also added background information to support our reasoning for soliciting comment about Method 7E stratification. Therefore, the EPA is extending the comment period to allow the public additional time to submit comments and supporting information on these and other aspects of the proposed rule.

DATES:

Comments on the proposed rule published September 8, 2015 (80 FR 54146) must be received on or before December 9, 2015.

ADDRESSES:

Comments. Written comments on the proposed rule may be submitted to the EPA electronically, by mail, by facsimile, or through hand delivery/courier. Please refer to the proposal (80 FR 54146) for the addresses and detailed instructions.Start Printed Page 61140
