March 9, 2017 – Federal Register Recent Federal Regulation Documents

This final rule adopts without change an interim final rule with request for comments published in the Federal Register on May 12, 2016. The Drug Enforcement Administration is placing the substance brivaracetam ((2S)-2-[(4R)-2-oxo-4-propylpyrrolidin-1-yl] butanamide) (also referred to as BRV; UCB-34714; Briviact) (including its salts) into schedule V of the Controlled Substances Act. This scheduling action is pursuant to the Controlled Substances Act, as revised by the Improving Regulatory Transparency for New Medical Therapies Act which was signed into law on November 25, 2015.

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Arizona Department of Environmental Quality (ADEQ) and Maricopa County Air Quality District (MCAQD) portions of the Arizona State Implementation Plan (SIP). These revisions were submitted by ADEQ in response to EPA's May 22, 2015, finding of substantial inadequacy and SIP call for certain provisions in the SIP related to affirmative defenses applicable to excess emissions during startup, shutdown, and malfunction (SSM) events. EPA is proposing approval of the SIP revisions because the Agency has determined that they are in accordance with the requirements for SIP provisions under the Clean Air Act (CAA or the Act).

We are adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. Arriel 2B turboshaft engines. This AD requires removing any pre-modification (mod) TU 158 hydro-mechanical metering unit (HMU) and replacing with a part eligible for installation. This AD was prompted by a report of an uncommanded in- flight shutdown (IFSD) on a single-engine helicopter, caused by a low returning spring rate of the needle of the HMU. We are issuing this AD to correct the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-300, -400, and -500 series airplanes. This proposed AD was prompted by a manufacturer's review that showed that the tank access door at a certain wing buttock line did not have an engineered ground path with the mating wing structure. This proposed AD would require replacing the tank access door, doing a check of the electrical bond, doing related investigative and corrective actions if necessary, and revising the maintenance or inspection program by incorporating an airworthiness limitation (AWL). We are proposing this AD to address the unsafe condition on these products.

The Coast Guard proposes to amend a special local regulation to change the method of providing notice to the public when enforcing the safety zone associated with the biennial Newport/Bermuda Race. The Coast Guard also proposes to establish permanent safety zones in Coast Guard Southeastern New England Captain of the Port (COTP) Zone for several recurring marine events. When the special local regulation or safety zones are activated and subject to enforcement, vessels and people may be restricted from portions of water areas that may pose a hazard to public safety. The revised special local regulation and safety zones would expedite public notification of the applicable marine events, and help protect the maritime public and event participants from hazards associated with these recurring marine events. We invite your comments on this proposed rulemaking.

We propose to adopt a new airworthiness directive (AD) for certain CFM International S.A. (CFM) CFM56-3, -3B, and -3C turbofan engines. This proposed AD was prompted by a report of dual-engine loss of thrust control that resulted in an air turn back. This proposed AD would require initial and repetitive checks of the variable stator vane (VSV) actuation system in the high-pressure compressor (HPC). We are proposing this AD to correct the unsafe condition on these products.
