Final Environmental Impact Statement (EIS) for Basing F-35 Squadrons at Miramar in 2020

West Coast Basing of F-35 Lightning II Joint Strike Fighter squadrons is expected at MCAS Miramar in 2020. Hanger construction and other preparations are well underway. The F35 will replace the F/A-18 Hornet at Miramar. In 2010, the Department of the Navy, in cooperation the Department of the Air Force, issued an Environment Impact Statement (EIS; also referred to as an Environmental Impact Report EIR) for the West Coast Basing of the F-35B. In 2018, the USMC issued a F-35C Noise Study February 2018** (Continuing Environmental Review Statement) for basing up to two F-35C squadrons in lieu of two F-35B squadrons at MCAS Miramar.

PURPOSE: Headquarters, United States Marine Corps (HQMC), Marine Corps Installations West (MCIWEST), and Marine Corps Air Station (MCAS) Miramar staffs have planned extensively for the introduction and home basing of the F-35B Lightning II aircraft at MCAS Miramar. On December 9, 2010, the Department of the Navy signed a Record of Decision (ROD) implementing Alternative 1 to base six operational squadrons at MCAS Miramar and five operational squadrons plus one operational test and evaluation (OT&E) squadron at MCAS Yuma (Navy 2010). Since the ROD was issued, changes to the Joint Strike Fighter Program have occurred, including changes to the aircraft series, number of aircraft, and construction requirements. The 2013 Marine Corps Aviation Plan directs two F-35C operational squadrons of 10 aircraft per squadron would be based on the west coast in lieu of two F-35B squadrons. To more accurately represent projected conditions, this analysis includes updated noise signatures and operational data for several aircraft types which became available subsequent to the ROD. This document presents the results of recent noise and air quality studies of the F-35C, to help decision-makers determine the need for supplemental National Environmental Policy Act (NEPA) analysis in accordance with Title 40 Code of Federal Regulations (CFR) 1502.9(c)(1)(i), Marine Corps Order (MCO) P5090.2A Section 12201.6.k, and USMC NEPA Manual Section 6.5.

F-35 PLANNING HISTORY AT MCAS MIRAMAR: From 2008-2010, an Environmental Impact Statement (EIS) was completed for USMC F-35B West Coast Basing. The ROD for that action was signed in December of 2010, with the decision to base six operational F-35B squadrons at MCAS Miramar. Since 2010, the USMC has adjusted its plans to include up to four F-35C squadrons in its inventory – two per coast (two each as part of 3rd Marine Aircraft Wing (MAW) on the West Coast in fiscal years 2019- 2024 and 2nd MAW on the East Coast in fiscal years 2024-2026) to be able to augment the Navy’s carrier air wings as needed. This document analyzes whether basing one or both West Coast F-35C squadrons at MCAS Miramar, in lieu of a corresponding number of F-35B squadrons, would represent a substantial change relevant to environmental concerns. Additionally, noise modeling data is now available for the F-35B, MV-22B, CH-53E, and KC-130J that was not incorporated into the 2010 noise analysis, so this document also analyzes whether that data constitutes significant new information relevant to environmental concerns and bearing on the Federal Action or its impacts.

DESCRIPTION OF SCENARIOS COMPARED: This report summarizes the results of noise and air quality studies based on a mix of two F-35C squadrons and four F-35B squadrons while incorporating the latest available noise data for the F-35B, MV-22B, CH-53E, and KC-130J. This is referred to as the “F-35C Scenario”. This report also presents the results of updates to the noise study for six F-35B squadrons reflected in the 2010 ROD and EIS. This is referred to as the “Updated ROD Scenario (Noise).” Air emissions data used in the 2010 EIS remain valid for the aircraft studied therein, so the 2010 ROD serves as the baseline for comparison to the F-35C Scenario for purposes of air quality analysis.

ABSTRACT from the 2010 FINAL ENVIRONMENTAL IMPACT STATEMENT FOR THE WEST COAST BASING OF THE F-35B

Lead Agency for the EIS: Department of the Navy
Cooperating Agency: Department of the Air Force
Title of Proposed Action: West Coast Basing of the F-35B
Designation: Final Environmental Impact Statement

October 2010

This Environmental Impact Statement (EIS) has been prepared by the Department of the Navy (DoN) and the United States Marine Corps (Marine Corps) in accordance with the National Environmental Policy Act (NEPA) of 1969, 42 United States Code §§ 4321-4374, as implemented by the Council on Environmental Quality (CEQ) regulations, 40 Code of Federal Regulations (CFR) §§ 1500-1508, DoN regulations NEPA 32 CFR 775, and Marine Corps Order P5090.2A (with Changes 1, 2), Marine Corps Environmental Compliance and Protection Manual, Chapter 12.

The Proposed Action addressed in this EIS would include: 1) basing of 11 operational F-3SB Joint Strike Fighter squadrons (176 aircraft), and 1 F-3SB Operational Test and Evaluation (OT&E) squadron (8 aircraft) on the West Coast of the United States; 2) construction and/or renovation of airfield facilities and infrastructure necessary to accommodate and maintain the F-3SB squadrons; 3) changes to personnel to accommodate squadron staffing; and 4) conducting F-3SB readiness and training operations to attain and maintain proficiency in the operational employment of the F-3SB and special exercise operations. The F-3SB aircraft would replace 126 legacy F/A-18A/B/C/D Hornet and 56 AV-8B Harrier aircraft in the Third Marine Air Wing (30 MAW) and 4th MAW.

Each operational squadron would consist of up to 16 F-35B aircraft. This EIS addresses the following basing alternatives: 1) Six operational squadrons at Marine Corps Air Station (MCAS) Miramar in San Diego County, California, and five operational squadrons plus one OT&E squadron at MCAS Yuma in southwestern Arizona; 2) Four operational squadrons at MCAS Miramar and seven operational squadrons plus one OT&E squadron at MCAS Yuma; 3) Seven operational squadrons plus one OT&E squadron at MCAS Miramar and four operational squadrons at MCAS Yuma; 4) One operational squadron plus one OT&E squadron at MCAS Miramar and ten operational squadrons at MCAS Yuma; and 5) Ten operational squadrons at MCAS Miramar and one operational squadron plus one OT&E squadron at MCAS Yuma.

Regardless of which basing alternative is ultimately selected, the Marine Corps would conduct F-3SB training and readiness operations within Department of Defense managed airspace and DON/Marine Corps training ranges located on the West Coast including: the Bob Stump Training Range Complex consisting of Chocolate Mountain Aerial Gunnery Range, Barry M. Goldwater Range West, Yuma Proving Ground, El Centro Range Complex, Dome Military Operations Area/Air Traffic Control Assigned Airspace, and the Imperial Air Traffic Control Assigned Airspace in Yuma County, Arizona, and Imperial and Riverside Counties in California. These training areas would also include the Barry M. Goldwater Range East managed by the Air Force.

This EIS evaluates the potential environmental impacts to the following resource areas: airfields and airspace; noise; air quality; safety and environmental health; land use; infrastructure and utilities; socioeconomics; community facilities and services; environmental justice; ground traffic and transportation; hazardous materials and waste; biological resources; topography, geology, and soils; water resources; and cultural and traditional resources. The Notice of Intent was published in the Federal Register on 15 January 2009, and the Notice of Availability of the Draft EIS was published on 21 May 2010.
