July 17, 2017 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) submission from Minnesota addressing the state board requirements of the Clean Air Act (CAA). EPA is also proposing to approve elements of Minnesota's submission addressing the infrastructure requirements relating to state boards for the 1997 ozone, 1997 fine particulate (PM2.5), 2006 PM2.5, 2008 lead (Pb), 2008 ozone, 2010 nitrogen dioxide (NO2), 2010 sulfur dioxide (SO2), and 2012 PM2.5 National Ambient Air Quality Standards (NAAQS). This SIP revision was submitted by the Minnesota Pollution Control Agency (MPCA) on May 26, 2016.

These special conditions are issued for the Pilatus Aircraft Ltd. PC-24 airplane. This airplane will have a novel or unusual design feature associated with installation of an autothrust system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This airplane will have a novel or unusual design features associated with installation of an electronic engine control. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature.

The Coast Guard is establishing two temporary safety zones on Lake Michigan in Calumet Harbor, in Chicago, IL. This action is necessary and intended to ensure safety of life on the navigable waters of the United States immediately prior to, during, and after a lakebed rock removal operation involving explosives. Entry of vessels or persons into these zones is prohibited unless specifically authorized by the Captain of the Port Lake Michigan.

The Commission is updating the competitive product list. This action reflects a publication policy adopted by Commission order. The referenced policy assumes periodic updates. The updates are identified in the body of this document. The competitive product list, which is re-published in its entirety, includes these updates.

The Environmental Protection Agency (EPA) is approving a July 7, 2016 state implementation plan (SIP) revision submitted by the State of Maryland. The July 7, 2016 SIP submittal sought removal of a regulation in its entirety from the approved Maryland SIP which addressed Maryland's defunct Clean Air Interstate Rule (CAIR) program and sought removal from the SIP of additional provisions which referenced Maryland's CAIR program in Maryland regulations addressing general air quality definitions and the control of emissions from pulp mills in Maryland. Additionally, the July 7, 2016 SIP submittal included an amendment to a Maryland regulation regarding the use of continuous emission monitoring (CEM) systems at Kraft pulp mill boilers and combustion units in order to clarify that CEM systems must meet requirements beyond those only related to certification. The July 7, 2016 SIP submittal removing references to CAIR in Maryland's regulations satisfies Maryland's obligation pursuant to an earlier rulemaking in which EPA granted final conditional approval of Maryland's amended regulation regarding the control of emissions from Kraft pulp mills contingent upon Maryland addressing the removal of references to CAIR from its regulations and SIP. Today's action thus also converts the prior conditional approval of the pulp mill regulation to a full approval. EPA's approval of the Maryland SIP is in accordance with the requirements of the Clean Air Act (CAA) and is under CAA authority.

This document proposes to amend the U.S. Customs and Border Protection (CBP) regulations to reflect that customs user fees and limitations established by the Consolidated Omnibus Budget Reconciliation Act (COBRA) will be adjusted for inflation in accordance with the Fixing America's Surface Transportation Act (FAST Act).

The Environmental Protection Agency (EPA) is correcting the addresses and agencies names for EPA Region 4 State and local agencies in EPA regulations. The jurisdiction of EPA Region 4 includes the States of Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina and Tennessee. Certain EPA air pollution control regulations require submittal of notifications, reports and other documents to the appropriate authorized State or local agency. This technical amendment updates and corrects agency names and the addresses for submitting such information to the EPA Region 4 State and local agency offices.

We propose to remove Airworthiness Directive (AD) 2017-01-06, which applies to certain Airbus Model A319-115, A319-132, A320-214, A320-232, A321-211, A321-213, and A321-231 airplanes. AD 2017-01-06 requires inspection and replacement of certain tie rod assemblies installed on the hinged fairing assembly of the main landing gear (MLG). We issued AD 2017-01-06 to detect and correct the absence of cadmium plating on the rod end threads of the tie rod assemblies. Since we issued AD 2017-01-06, we have determined that although cadmium plating might be absent, the rod end threads of the tie rod assemblies can withstand the expected environmental conditions, therefore the unsafe condition, as initially determined, does not exist.

We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G150 airplanes. This proposed AD was prompted by a report that the main entrance door (MED) opened during flight, and by the determination that the ``CABIN DOOR UNLOCK'' crew alerting system (CAS) message may extinguish before the handle latch pin is fully engaged. This proposed AD would require accomplishing an updated rigging procedure for the adjustment of the MED microswitch. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (CL-600), CL-600-2A12 (CL- 601 Variant), and CL-600-2B16 (CL-601-3A and CL-601-3R Variants) airplanes. This proposed AD was prompted by a report of laminated shims that may have been improperly installed at a certain wing tie beam. This proposed AD would require revising the maintenance or inspection program to incorporate certification maintenance requirement tasks that introduce revised checks of the tie beam. We are proposing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2007-13-08, for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2007-13-08 required repetitive inspections of the auxiliary power unit (APU) starter motor, APU inlet plenum, and APU air intake for discrepancies; repetitive cleaning of the APU air intake; and applicable corrective actions. This AD expands the applicability of AD 2007-13-08, and includes an optional terminating installation for the repetitive actions. This AD was prompted by a determination that the unsafe condition could occur on additional airplanes. We are issuing this AD to address the unsafe condition on these products.
