14647 Federal Register / Vol. 82, No. 54 / Wednesday, March 22, 2017 / Proposed Rules 
airworthiness directive (AD) for certain 
CFE Company (CFE) turbofan engines that published in the Federal Register on January 5, 2017. The proposed action that published in the Federal Register on January 5, 2017 was a duplicate of an NPRM, Directorate Identifier 2016– NE–21–AD, that published in the Federal Register on January 3, 2017. Accordingly, we withdraw the proposed rule that published in the Federal Register on January 5, 2017. 
DATES : As of March 22, 2017, the 
proposed rule published January 5, 2017 (82 FR 52) is withdrawn. 
FOR FURTHER INFORMATION CONTACT : 
Martin Adler, Aerospace Engineer, Engine Certification Office, FAA, 1200 District Avenue, Burlington, MA 01803; phone: 781–238–7157; fax: 781–238– 7199; email: martin.adler@faa.gov. 
SUPPLEMENTARY INFORMATION : The FAA 
proposed to amend 14 CFR part 39 with a proposed AD (82 FR 1258, January 5, 2017). Since we published the NPRM, Directorate Identifier 2016–NE–21–AD, in the Federal Register on January 5, 2017 (82 FR 1258), we discovered that it was a duplicate of an NPRM, Directorate Identifier 2016–NE–21–AD, that published in the Federal Register on January 3, 2017 (82 FR 52). This duplication created overlapping comment periods with different comment period closing dates, which is confusing to commenters. 
Withdrawal of the NPRM (82 FR 1258, 
January 5, 2017) constitutes only such action, and does not preclude the agency from issuing another notice in the future, nor does it commit the 
agency to any course of action in the future. 
Since this action only withdraws a 
notice of proposed rulemaking, it is neither a proposed nor a final rule. Therefore, Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979) do not cover this withdrawal.

Tobacco Product Standard for N- 
Nitrosonornicotine Level in Finished Smokeless Tobacco Products; Extension of Comment Period 
AGENCY : Food and Drug Administration, 
HHS. 
ACTION : Proposed rule; extension of 
comment period. 
SUMMARY : The Food and Drug 
Administration (FDA or the Agency) is extending the comment period for the proposed rule that appeared in the Federal Register of January 23, 2017. In the proposed rule, FDA requested comments on its proposal to establish a limit of N-nitrosonornicotine (NNN) in finished smokeless tobacco products. The Agency is taking this action in response to requests for an extension to allow interested persons additional time to submit comments. The Agency is also providing notice of a typographical error in a formula in the Laboratory Information Bulletin (LIB) titled, ‘‘Determination of N-nitrosonornicotine (NNN) in Smokeless Tobacco and Tobacco Filler by HPLC–MS/MS’’ (LIB No. 4620, January 2017). In accordance with the memorandum of January 20, 2017, from the Assistant to the President and Chief of Staff, entitled ‘‘Regulatory Freeze Pending Review’’, the Agency is also taking this opportunity to provide notice that, as with all regulatory actions subject to such memorandum, this proposed rule is being reviewed consistent with the memorandum.

SUPPLEMENTARY INFORMATION : In the 
Federal Register of January 23, 2017, FDA published a proposed rule with a 75-day comment period to request comments on our proposal to establish a limit for NNN in finished smokeless tobacco products. Comments on the proposed rule will inform FDA’s rulemaking to establish a tobacco product standard for NNN. 
The Agency has received requests for 
a 75-day extension of the comment period for the proposed rule. Each request expressed concern that the current 75-day comment period does not allow the public sufficient time to develop thoughtful responses to the proposed rule. 
The Agency also has received a 
request to clarify a formula in the Laboratory Information Bulletin (LIB) titled, ‘‘Determination of N- nitrosonornicotine (NNN) in Smokeless Tobacco and Tobacco Filler by HPLC– MS/MS’’ (LIB No. 4620, January 2017). Upon further review, FDA has determined that the formula for converting NNN on a wet weight basis to a dry weight basis contains a typographical error—some of the terms and variables in the numerator and denominator were inadvertently switched. FDA has revised the LIB to correct this error (LIB No. 4623, March 2017, available at https://www.fda.gov/ downloads/ScienceResearch/ FieldScience/UCM546874.pdf). We note that the typographical error in the LIB did not affect our calculations in the preamble of the proposed rule or the supporting analyses. 
FDA has considered the requests and 
is extending the comment period for the proposed rule for 90 days, until [July 10, 2017. The 90-day extension will provide 
additional time for interested persons to submit comments on all aspects of the proposed rule, including whether the approach proposed in the rule is appropriate.

Air Plan Approval; Washington: 
General Regulations for Air Pollution Sources, Energy Facility Site Evaluation Council 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : The Environmental Protection 
Agency (EPA) is proposing to revise the Washington State Implementation Plan (SIP) to approve updates to the Energy 
Facility Site Evaluation Council (EFSEC) air quality regulations. The EFSEC regulations primarily adopt by reference the Washington Department of Ecology (Ecology) general air quality regulations, which the EPA approved in the fall of 2014 and spring of 2015. Consistent with our approval of the Ecology general air quality regulations, we are also proposing to approve revisions to implement the preconstruction permitting regulations for large industrial (major source) facilities in attainment and unclassifiable areas, called the Prevention of Significant Deterioration 
(PSD) program. The PSD program for major energy facilities under EFSEC’s jurisdiction has historically been operated under a Federal Implementation Plan (FIP), in cooperation with the EPA and Ecology. If finalized, the EPA’s proposed approval of the EFSEC PSD program would narrow the FIP to include only those few potential facilities, emission sources, geographic areas, and permits for which EFSEC does not have jurisdiction or authority. The EPA is also proposing to approve EFSEC’s visibility protection permitting program which overlaps significantly with the PSD program in most cases.
