airspace revealed modification necessary due to the decommissioned Portland VOR/DME and Laker NDB navigation aids. Also, the geographic coordinates of the airport would be amended to coincide with the FAA’s aeronautical database.

Class E airspace designated as an extension to Class C airspace would be modified to an area 4.7 miles west and 4 miles east of the 044 ° bearing from Portland International Airport extending to 18 miles northeast of the airport. The lateral boundary for Class E airspace extending upward from 700 feet above the surface would be defined utilizing latitudinal and longitudinal reference points instead of navigation aids. This would not change the lateral boundaries or operating requirements of the airspace.

Class E airspace designations are published in paragraph 6003 and 6005, respectively, of FAA Order 7400.9Y, dated August 6, 2014, and effective September 15, 2014, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order. Regulatory Notices and Analyses

The FAA has determined this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this proposed regulation; (1) is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified this proposed rule, when promulgated, would not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Environmental Review

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures’’ prior to any FAA final regulatory action. List of Subjects in 14 CFR Part 71

Services, Federal Aviation Administration, 800 Independence Avenue SW., Washington, DC 20591; telephone: (202) 267–8783.

**SUPPLEMENTARY INFORMATION :**  Authority for This Rulemaking

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority.

This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it would modify the restricted area airspace at Chocolate Mountains, CA, to enhance aviation safety and accommodate essential USMC training requirements. Background

The Chocolate Mountain Aerial Gunnery Range (CMAGR), located in Imperial and Riverside Counties, CA is primarily used for live-fire aviation and ground warfare training conducted by USMC and Navy forces. Marine aviation plays a crucial role in the ability of Marine Air-Ground Task Forces (MAGTF) to conduct maneuver warfare. The ultimate goal of Marine aviation is to attain the highest possible combat readiness to support expeditionary maneuver warfare while preserving and conserving Marine forces and equipment. Embedded within combat readiness is the requirement that Marine aviation units maintain the ability to rapidly, effectively, and efficiently deploy a combat-capable aircrew and aircraft on short notice, and maintain the ability to quickly and effectively plan for crises and/or contingency operations. R–2507W would allow Marine aviation to attain and maintain this capability.

Current procedures require the periodic renewal of the CFAs over this area. Because nonparticipating aircraft may transit the CFAs without limitation and without warning, safety of flight concerns often result in lengthy training interruptions and failure to meet training requirements. A higher-level demand for greater throughput of both ground and aviation training in order to support real world operations will likely increase the frequency of these incidents. The USMC considered the existing R–2507N and the adjacent R– 2507S restricted areas in order to meet the expanded training requirements. The existing restricted areas, which are primarily used for aerial ordnance delivery and air strikes, are incompatible with required co-use ground training activities. Alternate location suitability studies were conducted to examine alternatives for the ground training activities. The studies determined that the training capabilities offered in the proposed R– 2507W are unique and cannot be replicated elsewhere without significant cost, time, and undue degradation or failure to meet USMC requirements.

Comments Invited

Interested parties are invited to participate in this proposed rulemaking by submitting such written data, views, or arguments as they may desire. Comments that provide the factual basis supporting the views and suggestions presented are particularly helpful in developing reasoned regulatory decisions on the proposal. Comments are specifically invited on the overall regulatory, aeronautical, economic, environmental, and energy-related aspects of the proposal.

Communications should identify both docket numbers (FAA Docket No. FAA– 2015–2193 and Airspace Docket No. 15– AWP–8) and be submitted in triplicate to the Docket Management System (see

**ADDRESSES** section for address and phone number). You may also submit comments through the Internet at www.regulations.gov.

An informal docket may also be examined during normal business hours at the office of the Operations Support Group, Western Service Center, Federal Aviation Administration, 1601 Lind Ave. SW., Renton, WA 98057.

Persons interested in being placed on a mailing list for future NPRMs should contact the FAA’s Office of Rulemaking, (202) 267–9677, for a copy of Advisory Circular No. 11–2A, Notice of Proposed Rulemaking Distribution System, which describes the application procedure. The Proposal

This proposal would establish new restricted area. R–2507W to accommodate live direct and indirect surface to surface fires associated with established live fire ranges and maneuver areas supporting Naval Special Warfare and Marine Corps ground unit training. This proposed restricted area is required to effectively de-conflict Department of Defense and civilian air traffic from hazards associated with live fire training.

Specific aviation activities and maximum altitudes within the R– 2507W would include both live fire and non-live fire aviation training activities such as Basic Ordnance Delivery, Close Air Support, Air-to-Air Gunnery, Laser Ranging and Designating, and Air Strikes. As part of the Marine Corps’ training in R–2507, the Marine Corps Air Command and Control organization will develop a battle space management plan. This plan will establish ground fire support and airspace coordination measures in a way that integrates ground and air operations in planning and execution within the MAGTF. Supersonic flight will not be conducted as part of the above aviation training activities.

Surface-to-surface and surface-to-air activities conducted within the R– 2507W would include live fire fromvarious small arms, machine guns, antitank weapons, mortars, and hand grenades. Direct fire weapons will be used in this area 6–24 hours per day, no less than 300 days per year. A minimum of 40 percent use of the planned live fire ranges will occur during hours of darkness (from 2200–0700).


### 42763 Federal Register / Vol. 80, No. 138 / Monday, July 20, 2015 / Proposed Rules

Expansion of the current restricted area complex supports an increase in both Marine Corps and Naval aviation and ground training requirements. In addition, the expansion would allow critically required co-use of R–2507W in order to meet those increased training requirements. Regulatory Notices and Analyses

The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under Department of Transportation (DOT) Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal.
