Short Takes – 4-2-26 - Federal Register Edition

 Implementing the Freedom of Information Act and Privacy Act. Federal Register ONCD notice of proposed rulemaking. Summary: The Office of the National Cyber Director (ONCD) is issuing its first Freedom of Information Act (FOIA) and Privacy Act regulations. These regulations reflect ONCD's process for responding to requests for information and affirm its commitment to provide the fullest possible disclosure of records to the public. 

National Emission Standards for Hazardous Air Pollutants: Chemical Manufacturing Area Sources Technology Review. Federal Register EPA CMAS NESHAP final rule. Summary: The Environmental Protection Agency (EPA) is finalizing amendments to the National Emission- Standards for Hazardous Air Pollutants (NESHAP) for the Chemical Manufacturing Area Source (CMAS) categories pursuant to a technology review under Clean Air Act (CAA) section 112(d)(6). Specifically, the EPA is finalizing new leak detection and repair (LDAR) requirements for equipment leaks and heat exchange systems in organic hazardous air pollutant (HAP) service. In addition, the EPA is taking final action to add standards for pressure relief devices (PRDs) and pressure vessels; require electronic reporting for notification of compliance status (NOCS), performance test reports, and periodic reports; and require continuous performance testing of non-flare air pollution control devices (APCD). The EPA is not finalizing the proposed area source category for chemical manufacturing with ethylene oxide (EtO) or related standards at this time. 

Implementing Section 927 Waiver Process for Certain Unmanned Aircraft Operations. Federal Register FAA notice. Summary: As a part of the FAA Reauthorization Act of 2024, Congress authorized FAA to enable unmanned aircraft operations through waivers to applicable federal aviation regulations instead of initiating regulations or requiring operators to seek regulatory exemptions. This notice explains how FAA will implement that authority. 

Pipeline Safety: Class Location Change Requirements; Response to Petition for Reconsideration. Federal Register PHMSA response to petition for reconsideration. Summary: PHMSA alerts the public to a petition for reconsideration and PHMSA's response. 

Federal Motor Vehicle Safety Standards; Modernization of FMVSS No. 110 To Accommodate ADS-Equipped Vehicles. Federal Register NHTSA notice of proposed rulemaking. Summary: NHTSA is proposing to amend Federal Motor Vehicle Safety Standard (FMVSS) No. 110, “Tire selection and rims and motor home/recreation vehicle trailer load carrying capacity information for motor vehicles with a GVWR of 4,536 kilograms (10,000 pounds) or less.” The proposed modification would amend a single section of the standard to enable compliance by affixing the required placard on the left side of the vehicle when there is not a “driver's side” for vehicles equipped with Automated Driving Systems (ADS) that do not have manually operated driving controls. This rulemaking would allow flexibility in complying with the standard without detriment to vehicle safety. This action is part of a larger NHTSA effort to address vehicle automation in the agency's regulations.
