Revisions to Test Methods, Performance Specifications, and 
Testing Regulations for Air Emission Sources; Extension of Comment 
Period

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.
