Signal Peak Energy, LLC has submitted a petition to the Mine Safety and Health Administration (MSHA) requesting a change to existing safety standards at Bull Mountains Mine No. 1 in Montana. They want to use Dräger X-plore 8700 Powered Air Purifying Respirators (PAPRs) instead of the current equipment, claiming this new model offers better performance and safety. Although these devices are not directly approved by MSHA, they are certified as safe for use in facilities with explosive gases and dust. Signal Peak Energy has detailed safety measures and training requirements to ensure the equipment keeps miners protected.

The U.S. Environmental Protection Agency (EPA) has announced plans to submit Information Collection Requests (ICRs) for review and approval in line with the Paperwork Reduction Act (PRA). They are requesting public feedback on aspects of these proposed information collections. These ICRs, which are extensions of currently approved ones, involve various industrial sectors, such as sulfuric acid manufacturing and polymeric coating of substrates, and cover topics like emissions standards and recordkeeping requirements. Public comments are invited by April 9, 2021.

The Federal Aviation Administration (FAA) has issued a final rule that changes the airspace rules for several towns in Minnesota. This action includes updating and revoking the Class E airspace areas due to the removal of certain navigation beacons. The rule involves updating the airport names and geographic coordinates to match FAA records and supports instrument flight operations at these airports. It also revokes the airspace at Silver Bay Municipal Airport as it is no longer needed. The FAA concluded that these are routine updates that have minimal environmental impact and do not significantly affect small business entities.

The Federal Aviation Administration (FAA) is proposing changes to the Class E airspace at Battle Mountain Airport in Nevada. These changes include adjusting the size and boundaries of the airspace to better support the safety and efficiency of instrument flight rules (IFR) operations. Specifically, the proposal involves modifying, establishing, or removing certain sections of Class E airspace around the airport and updating related legal descriptions. The FAA invites public comments on these proposed changes until February 21, 2025.

The Federal Aviation Administration has updated the airspace around Buckley Space Force Base in Aurora, Colorado, to improve safety and flight management. The changes include expanding the boundaries of Class D and Class E airspace, removing some Class E airspace that is no longer needed, and updating the legal descriptions to match official records. These modifications will help better manage flights landing and taking off under both instrument and visual flight rules. The changes will be effective starting February 20, 2025.

The National Highway Traffic Safety Administration (NHTSA) has issued a final rule to modify event data recorders (EDRs) requirements. The rule changes the duration and frequency at which EDRs record pre-crash data from 5 seconds at 2 Hz to 20 seconds at 10 Hz. These changes, effective by September 2027 for most manufacturers, aim to provide investigators with better data to understand vehicle crashes. The rule responds to a mandate by the Fixing America's Surface Transportation (FAST) Act and includes allowances for small-volume and limited-line manufacturers to comply by later dates.

The Federal Aviation Administration (FAA) has issued a final rule to amend and establish certain airspace areas in Fort Riley, Manhattan, and Junction City, KS. These changes affect the Class D and Class E airspace around Marshall Army Airfield, Manhattan Regional Airport, and Freeman Field, and are due to the decommissioning of some navigation beacons. The updates include adjustments to airspace dimensions and extensions, and corrections to geographic coordinates. The FAA clarifies that these changes do not alter current flight paths or altitudes used by aircraft.

The Department of Labor is seeking public comments on a proposed information collection related to ventilation in underground coal mines. This request is being reviewed by the Office of Management and Budget as part of the Paperwork Reduction Act. The safety and health standards aim to ensure proper ventilation to protect miners from harmful gases and dust. The proposal includes tests and recordkeeping requirements to maintain and adjust ventilation systems, ensuring miner safety in harsh underground conditions.

The Federal Aviation Administration (FAA) has issued a final rule affecting the airspace around Northeast Wyoming Regional Airport in Gillette, WY. This rule eliminates the Class D airspace, creates a new Class E surface area, and modifies existing Class E airspace to better support departing and arriving aircraft. These changes are intended to enhance safety following the permanent closure of the airport's control tower. The FAA determined that this rule does not have significant economic or environmental impacts.

The Mine Safety and Health Administration (MSHA) has received a petition from Peabody Midwest Mining, LLC requesting a change to existing safety rules. The petition seeks permission to use battery-powered radios in mining operations, arguing these radios provide the same level of safety as the current standards. Peabody explains that the previously approved radios are no longer available, hence the need to use alternative radios that are safe and practical for the work environment. Comments on this petition are being accepted until January 6, 2025.
