### DoN SIP Emissions Growth Increment

May 2011 ES-1 

## EXECUTIVE SUMMARY Navy Region Southwest (NRSW) and the Marine Corps Installations West (MCIWEST) have initiated an effort to estimate emission increases from potential operational changes through Year 2027 for the Department of the Navy (DoN) installations in San Diego County. This information is submitted to the San Diego Air Pollution Control District (SDAPCD) to be included in the 2012 8-hr Ozone Attainment Plan for the San Diego Air Basin (SDAB). The inclusion of the projected military emissions growth in the Attainment Plan would proactively address the Environmental Protection Agency (EPA) General Conformity requirements for federal actions in San Diego County. In addition to the anticipated DoN projects, this emissions growth assessment also includes emissions growth from potential upcoming Coast Guard projects. The data presented in this document represent the best available information for potential federal actions and their associated emissions at the time of this submission. URS and the DoN will communicate closely with SDAPCD during the Attainment Plan preparation process to refine the data presented here based on SDCAPCD comments, any further refinements in calculations, and updated information obtained. However, no significant changes to the information presented here are currently anticipated. The DoN emphasizes that all growth information regarding proposed projects and emission estimates are notional for all potential new weapons systems, and as such, are best estimates at this time and subject to change. Further, the DoN must comply with the provisions of theNational Environmental Policy Act (NEPA) and other laws and regulations that prohibit predecisional actions. Final decisions about specific projects or actions for new weapons systems cannot be made until NEPA and other applicable requirements are met. After analyzing the potential upcoming DoN and Coast Guard projects, emissions growth is expected for the two ozone precursor criteria pollutants (i.e., oxides of nitrogen (NOx

## ) and volatile organic compounds (VOC)). Therefore, the DoN and Coast Guard request that emissions growth allowances for NOx 

## and VOC be included in the Attainment Plan as Military Growth Increment line items, expressed in tons per day. Detailed descriptions of potential projects, emissions, and operational assumptions are presented in the following sections. In addition to the known potential projects, an additional 20% emissions growth allowance is requested to account for the currently unanticipated DoN and Coast Guard actions, currently unknown new weapon systems or training operations, unknown large-scale construction projects or other operational changes that may occur through 2027.

### DoN SIP Emissions Growth Increment

May 2011 ES-2 

## Table ES-1 shows a summary of the requested growth increment by year, including the additional 20% growth. Based on the information currently available for potential operational changes, the years 2022 through 2025 yielded a negative emission change for VOC emissions. The negative values were removed from the emissions growth totals by year. Table ES-2 presents the emissions by year and by source category, with additional 20% growth included. In summary, the DoN and Coast Guard request that 1,616 tons per year of NOx (4.43 tons per day) and 356.2 tons per year of VOC (approximately 1 ton per day) be incorporated in the upcoming Attainment Plan for San Diego County, with the understanding that the DoN and Coast Guard may use the allowable growth as needed, at any time during the term of the Plan.

## 1. INTRODUCTION The DoN and Coast Guard are requesting an emissions growth allowance in the upcoming San Diego County 8-hr Ozone Attainment Plan to proactively address the EPA General Conformity requirements. San Diego is the largest Pacific port of the Department of the Navy (DoN, including both the Navy and Marine Corps) and is home to many of the soldiers and civilians that serve the nation’s military. The DoN takes great pride in the efforts undertaken to help improve the air quality for the service members, their families, and the rest of the population living in San Diego. As such, the continuous improvement of air quality remains one of the DoN’s top priorities. The emissions growth allowance requested for this Attainment Plan will allow the DoN and Coast Guard to proactively plan potential changes to their operations while meeting all the applicable regulatory requirements. The DoN and Coast Guard have evaluated upcoming potential actions that would create a net change in emissions over the next 16 years. These projects consist of the addition of ground and tactical support vehicles, new aircraft, ships, and utilities. The data presented in this document represent the best available information for growth emission estimates available at the time of this submission. URS, the DoN, and the Coast Guard will communicate closely with SDCAPCD during the SIP preparation process to refine the data presented here based on SDCAPCD comments. Any further refinements in calculations, and updated information will be obtained. However, no significant changes to the information presented here are currently anticipated. The DoN and Coast Guard emphasize that all growth information regarding proposed projects and emission estimates are notional for all potential new weapons systems, and as such, are best estimates at this time and subject to change. Further, the DoN and Coast Guard must comply with the provisions of the National Environmental Policy Act (NEPA) and other laws and regulations that prohibit pre-decisional actions. Final decisions about specific projects or actions for new weapons systems cannot be made until NEPA and other applicable requirements are met. Detailed descriptions of projects, emissions, and operational assumptions are presented in the following sections. The remainder of this report is organized as follows:

 Section 2.0 – Marine Corps Anticipated Actions and Estimated Emissions
 Section 3.0 – Navy Anticipated Actions and Estimated Emissions
 Section 4.0 – Coast Guard Anticipated Actions and Estimated Emissions
 Section 5.0 – Conclusion

## TACTICAL 

## S UPPORT 

## E QUIPMENT 

## The projects identified in the ground and tactical support equipment source category include the High-Mobility Multi-Purpose Wheeled Vehicle (HMMWV) replacement with the Joint Light Tactical Vehicle (JLTV), the vehicle alternative fuels’ goals, the Amphibious Assault Vehicle (AAV) replacement/upgrade, and vehicle operations associated with the possible relocation of the Marine Corps Outside the Contiguous United States (OCONUS) operations to San Diego County. The following subsections provide the details regarding the overall projects, assumptions, emission factor references, and emissions calculated for this emissions growth assessment.
2.1.1 HMMWV Replacement with the JLTV The High-Mobility Multi-Purpose Wheeled Vehicle (HMMWV) will be replaced by the Joint Light Tactical Vehicle (JLTV), which is a U.S. Army and Marine Corps joint effort. Currently, the Marine Corps is set to purchase 5,500 units, with full production projected by 2015. The JLTV program will include a greater payload, additional armor, and a larger engine, as compared to the HMMWV. Emission factors for the HMMWV and JLTV were obtained from the U.S. Army Fuels and Lubricants Research Facility’s Interim Report Number 376, Emissions from a 6.5L HMMWV Engine on Low Sulfur Diesel Fuel and JP-8, published in 2004 The emissions were based on assumptions that one third (1/3) of the JLTVs will be located in San Diego, each JLTV will operate 500 hours per year, and the emission factors for the HMMWV and JLTV, in units of grams per brake horse power per hour (g/bhp-hr), are equivalent. Table 2-1 presents the emissions from the HMMWV replacement with JLTV.

## 2.1.2 Alternative Fuels The Secretary of the Navy has set a goal to use 50% of alternative fuels for military applications by 2020. To help reach this 50% benchmark, fleet vehicles may be required to use B100 (i.e., 100% biofuel) on all fleet vehicles that currently use B20 (i.e., 20% biofuel). However, the use of B100 is known to decrease fuel efficiency by approximately eight percent and increase NO x 

## emissions by an additional eight percent as compared to B20.
To estimate this increase in NO x 

## emissions, the 2009 actual NOx 

## emissions from all Marine Corps ground support and tactical support equipment was multiplied by 16% (i.e., 8% increase from additional fuel and 8% additional NO x 

## emissions. This showed that the use of B100 would increase the NO x 

## emissions by approximately 16 tons. Table 2-2 presents the emissions from the alternative fuel replacement program.

## 2.1.3 AAV Replacement/Upgrade The Marine Corps had planned to replace the aging Amphibious Assault Vehicle (AAV) with the Expeditionary Fighting Vehicle (EFV). However, on 6 January 2011, Secretary of Defense Robert Gates announced that the EFV program will be cancelled. Replacement programs such as upgrading the existing AAV, creating new Amphibious Combat Vehicles (ACVs), and Marine Personnel Carriers (MPCs) are being considered. Since these replacement vehicles are early in the planning stages, vehicle-specific emissions data are not available. Therefore, it was assumed that the AAV replacement vehicle emissions will be equivalent to the Advanced Amphibious Assault Vehicle (AAAV) emission as described in the Environmental Impact Statement for the Advanced Amphibious Assault Vehicle Marine Corps Base Camp Pendleton , published in 2003. Table 2-3 presents the emissions for the AAV replacement/upgrade program.

## 2.1.4 Vehicle Operations Due to the Possible Relocation of OCONUS Operations to San Diego County Due to the high risk of disruption of normal operations resulting from natural disasters (e.g., storm surges, earthquakes, volcanoes), the Operations Outside the Contiguous United States (OCONUS) program may be transferred to facilities located in San Diego County. To plan for this contingency, the Marine Corps would like to incorporate OCONUS vehicle emissions, as presented in the Final Environmental Impact Statement for the Guam and CNMI Military

## Relocation , published in 2010. The EIS analysis included emissions from off-base vehicle operations. Based on the possible relocation, Marines and their dependents are estimated to increase off-base vehicle miles traveled from 3,535,224 to 4,160,544 by 2025. On-base vehicle commuter traffic and training operations for the additional Marines will also increase emissions. Table 2-4 presents the additional vehicle emissions due to the possible relocation of Marine Corps OCONUS operations to San Diego.

## 2.2 AIRCRAFT 

## Two potential projects were identified for the aircraft source category. These projects consist of the CH-53K upgrade to CH-53K and the aircraft emissions due to the possible relocation of OCONUS operations.
2.2.1 CH-53E Helicopter Upgrade to CH-53K Beginning in 2018, the Marine Corps will begin upgrading their fleet of CH-53E Super Stallions to the CH-53K. This upgrade will enable the aircraft to have a lift capacity and range twice that of its predecessor. The new aircraft will be equipped with three General Electric GE38-1B engines rated at 7,500 shaft horse power (shp). Since the CH-53K only recently passed Critical Design Review in August 2010, and has yet to go into test production, Aircraft Environmental Support Office (AESO) has not had the opportunity to test these new engines nor was able to make any recommendations on calculating emissions. Therefore, an assumption was made that the program emissions for the CH-53K upgrade will be equal to the MV-22 program, a similar program. Table 2-5 presents the emissions from the CH-53K Helicopter Upgrade.

## LCS-2) The distribution of LCS-1s and LCS-2s arriving at the San Diego Air Basin (SDAB) is unknown at this time. Since LCS-2s have a slightly higher emission profile than the LCS-1s, it was conservatively assumed that all LCS in the SDAB will be LCS-2 Independence Class ships. The LCS-2 uses two 12,200-hp MTU 20V 8000M91 engines for propulsion, two 1,125-hp MTU 8V-396 TE54 engines for power generation, and one 1,125-hp MTU 8V-396 TE54 engine for bow thrust, while the ship is within zero to three nautical miles offshore. Emission factors for the engines were estimated, assuming each engine will operate a maximum of 40 hours per year within zero to three nautical miles offshore, and that one trip through San Diego Harbor, out to three nautical miles, will take approximately 1.35 hours. The remaining data needed to derive the emission factors per engine is proprietary to the Navy and cannot be released to the public. The Navy plans to procure a total of 16 LCS ships beginning in FY 2012 through FY 2015, at a rate of six the first year and five the two subsequent years. All 16 ships are expected to be homeported within the SDAB. Table 3-1 presents the estimated emissions for the LCS-2s.

## (CVN-78) The CVN-78 Gerald R. Ford Class is to be the lead ship of her class of supercarriers. The main propulsion and power-generating engines of this ship are driven by two A1B nuclear reactors. The ship will, however, carry four 6,000-hp Colt-Pielstick 16PA6B-STC diesel emergency generators. Emission factors for the four Colt-Pielstick engines were estimated, assuming each engine will operate a maximum of seven hours per year within zero to three nautical miles offshore, at full load. The remaining data needed to derive the emission factors per engine is proprietary to the Navy and cannot be released to the public. Construction of the CVN-78 began in August 2005 and is expected to join the Navy fleet in 2015. The CVN-79 and CVN-80 are expected to join the fleet in 2019 and 2023, respectively. Table 3-2 presents the estimated emissions for the three Gerald R. Ford Class supercarriers.

## The LPD-17 uses its four 10,400-hp Colt-Pielstick PC2.5STC engines for propulsion and two 3,350-hp Caterpillar 3608 engines for power generation while the ship is within zero to three nautical miles offshore. Emission factors for LPD-17 were estimated assuming the ship will operate a maximum of 66 hours per year within three miles offshore. The four Colt-Pielstick engines will operate at 25% power and the two Caterpillar engines will operate at 50% power. The remaining data needed to derive the emission factors per engine is proprietary to the Navy and cannot be released to the public. The Navy currently operates two LPD San Antonio Class ships within the SDAB. Four more ships are under construction and two are expected to join the Navy San Diego fleet in 2012. Only the emissions for the two additional ships will be included in the emissions totals of thisconformity evaluation. Table 3-3 presents the estimated emissions for the additional two LPD17s.

## design work scheduled to begin in FY2012 or FY2013, information regarding the type of engines and emissions generated from this ship are unavailable. Therefore, it is assumed that the emissions from this ship will be equal to that of its predecessor, the DDG-51 Flight IIA. The homeports of this ship have also not been identified by the Navy. Therefore, it is assumed that half of the 24 ships will be homeported within the SDAB and will be produced at a rate of one ship per year from FY2016 through FY2027.

## 4. COAST GUARD ANTICIPATED ACTIONS AND ESTIMATED EMISSIONS The Coast Guard evaluated all the potential projects subject to the EPA General Conformity requirements. Following a review of the planned projects, the Coast Guard determined that only one ship will be introduced to the San Diego Air Basin (SDAB). The following subsection provides the details regarding the ship type, assumptions needed to estimate emissions, emission factor references, and the total emissions estimated for the project.

## (NSC) The National Security Cutter (NSC) is the flagship of the Coast Guard fleet. The ship uses a 30,565-hp, gas-powered turbine engine for propulsion and two 9,655-hp internal combustion engines for power generation. At this time, four NSCs are expected to arrive, at a rate of one per year, beginning in 2013. Shortly after the first two arrive, two smaller existing high efficiency cutters (WHEC) will be relocated outside the SDAB. The net difference in emissions from the addition of the 4 NSCs and the relocation of the WHECs outside SDAB was included in this evaluation. Emissions data for each ship was provided by Yvan Le of the Coast Guard and is presented in Table 4-1.

## 5. CONCLUSION In summary, the DoN and Coast Guard request that 1,616 tons per year of NOx (4.43 tons per day) and 356.2 tons per year of VOC (approximately 1 ton per day) be incorporated in the upcoming Attainment Plan for San Diego County as Military Growth Increment line items, expressed in tons per day, with the understanding that the DoN and Coast Guard may use the allowable growth as needed, at any time during the term of the Plan.
