ENVIRONMENTAL ASSESSMENT ADDRESSING IMPLEMENTATION OF THE 

REAL PROPERTY MASTER PLAN AT DEFENSE DISTRIBUTION CENTER,

SUSQUEHANNA

Responsible Agency: Defense Logistics Agency (DLA).

Affected Location: Defense Distribution Center, Susquehanna.

Report Designation: Environmental Assessment (EA).

Abstract: The DLA proposes to implement the installation’s Real Property Master Plan (RPMP) and its 

component plans for Defense Distribution Center, Susquehanna in Pennsylvania. The RPMP provides the 

direction for the future development of the installation over the next 20 to 30 years and identifies a series 

of building, infrastructure, and transportation projects that would ensure that the installation is able to 

meet its current and future mission requirements in a sustainable and environmentally conscious manner. 

Implementing the projects in the RPMP would replace undersized, outdated buildings and infrastructure 

with modern, energy-efficient, sustainable buildings and infrastructure. The proposed projects include the 

construction of 4,201,966 square feet (ft2

) of buildings and the demolition of 2,503,790 ft2 of buildings, 

which would result in an increase in impervious surface and parking places. Additionally, the proposed 

projects include a transit and non-motorized transportation system consisting of two transit hubs; multiple 

bus stops; a variety of bus, pedestrian, and bicycle routes; and rail access to reduce truck conveyance.

Component plans of the RPMP include the Net-Zero Energy Plan (NZEP), Sustainability Plan (SP), 

Integrated Natural Resources Management Plan (INRMP), and Integrated Pest Management Plan (IPMP) 

for the installation. The NZEP balances the installation’s future energy demand from buildings, industrial 

processes, fleet vehicles, and equipment with onsite and offsite renewable energy production. The SP 

provides a pathway for the installation to move toward compliance with relevant Federal mandates 

regarding sustainability. The INRMP is the installation’s plan for managing its natural resources while 

ensuring the success of the military mission. The IPMP is the installation’s plan for its pest management 

program. 

Implementation of the NZEP, SP, INRMP, and IPMP would enable the installation to reduce energy and 

fossil fuel use, increase alternative fuel use, achieve a net-zero energy footprint, meet or exceed relevant 

Federal sustainability mandates, practice sound natural resources stewardship, comply with environmental 

policies and regulations, and reduce reliance on pesticides while reducing real property damage and 

maintenance costs.

Under the No Action Alternative, DLA would not implement the RPMP or its component plans. In 

general, implementation of the No Action Alternative would require that the DLA continue to use the 

existing outdated, undersized, and inefficient facilities and abandon the proposed infrastructure 

enhancements, sustainability improvements, and natural resources projects of the component plans, which 

would hamper the ability of the installation to meet its current and future mission requirements. The 

No Action Alternative would not meet the purpose of and need for the Proposed Action.

No significant effects on environmental resources would be expected from the Proposed Action. 

Insignificant, adverse effects on recreation, geological resources, water resources, and transportation and 

infrastructure would be expected. Insignificant, beneficial effects on airspace management and safety, 

land use and recreation, noise, air quality, geological resource, water resources, biological resources, 

transportation and infrastructure, and hazardous materials and wastes also would be expected.

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

1.0 PROPOSED ACTION PURPOSE AND NEED

1.1 Introduction

Defense Distribution Center, Susquehanna is a Defense Logistics Agency (DLA) installation in New 

Cumberland, Pennsylvania, approximately 3 miles southeast of downtown Harrisburg (see Figure 1.1). It

is located on U.S. Army land permitted to DLA and consists of approximately 850 acres of land with 

more than 150 buildings. The installation employs approximately 3,050 military and civilian personnel 

(DLA 2013a). 

This Environmental Assessment (EA) addresses the DLA’s proposal to implement the installation’s Real 

Property Master Plan (RPMP) and its component plans, which include the Net-Zero Energy Plan (NZEP), 

Sustainability Plan (SP), Integrated Natural Resources Management Plan (INRMP), and Integrated Pest 

Management Plan (IPMP). All of the component plans affect the RPMP; however, the NZEP and SP are 

the primary drivers of the plan. The RPMP provides the direction for future development of the 

installation over the next 20 to 30 years and identifies potential projects that would ensure that the 

installation is able to meet its current and future mission requirements. It includes a Future Land Use

Plan, Capital Investment Strategy, and Future Development Plan. 

This EA analyzes the potential for significant environmental impacts associated with the Proposed Action 

and alternatives, including the No Action Alternative. It has been prepared in compliance with the 

National Environmental Policy Act (NEPA); Council on Environmental Quality (CEQ) regulations 

implementing NEPA (Title 40 Code of Federal Regulations [CFR] Parts 1500–1508); U.S. Department of 

Defense (DOD) Directive 6050.1, Environmental Considerations in DOD Actions; DLA Regulation 

(DLAR) 1000.22, Environmental Considerations in Defense Logistics Agency Actions; and other 

applicable DLA issuances (e.g., regulations, directives, memorandums, instructions). 

1.2 Purpose of and Need for the Proposed Action

The purpose of the Proposed Action is to implement the installation’s RPMP and its component plans to 

establish a foundation providing direction for the future development of the facilities, infrastructure, 

transportation system, and environmental conditions at the installation. The Proposed Action is needed to 

ensure that the installation is able to meet its current and future mission requirements while protecting its

natural resources and ensuring the energy efficiency and sustainability of the installation.

1.3 Scope of the Analysis

The scope of the analysis includes the range of actions, alternatives, and potential impacts to be 

considered. The scope of the Proposed Action and alternatives considered in this EA are presented in 

Section 2. In accordance with CEQ regulations, the No Action Alternative has been analyzed to provide 

the baseline against which the potential environmental impacts of implementing the action alternatives 

can be compared.

This EA analyzes the potential impacts of implementing the RPMP and its component plans, which 

would guide the siting, design, and timing of future projects to meet current and future mission 

requirements and ensure development is conducted in a sustainable and environmentally conscious 

manner. 

Environmental impacts associated with the construction, demolition, and operational activities of the 

individual projects in the RPMP and its component plans will be addressed in separate NEPA 

documentation as those projects are further defined. Additionally, this EA does not address

personnel-level changes due to mission changes or installation consolidation (i.e., transfer of personnel 

from Naval Support Activity Mechanicsburg to Defense Distribution Center, Susquehanna).

1.4 Summary of Key Environmental Compliance Requirements

1.4.1 National Environmental Policy Act

The NEPA, 42 United States Code 4321 et seq., was signed into law on January 1, 1970. The Act

establishes a national environmental policy and goals for the protection, maintenance, and enhancement 

of the environment and provides a process for implementing these goals within the Federal agencies. The

Act also establishes the CEQ to coordinate Federal environmental efforts. The process for implementing 

NEPA is outlined in 40 CFR Parts 1500–1508. The CEQ regulations specify that an EA serves to briefly 

provide evidence and analysis for determining whether to prepare a Finding of No Significant Impact 

(FONSI) or an Environmental Impact Statement (EIS). As part of the EA process, DLA will determine 

whether the Proposed Action would have the potential to result in significant impacts. If such impacts are 

predicted, then DLA would decide whether to mitigate impacts below the level of significance, undertake 

the preparation of an EIS, or select the No Action Alternative. The DLA’s implementing regulation for 

NEPA is DLAR 1000.22, Environmental Considerations in Defense Logistics Agency Actions.

1.4.2 Applicable Environmental and Regulatory Compliance

The NEPA process does not replace procedural or substantive requirements of other environmental 

statutes and regulations. It addresses them collectively in the form of an EA or EIS, which enables the 

decisionmaker to have a comprehensive view of major environmental issues and requirements associated 

with the Proposed Action.

1.5 Agency Coordination and Public Involvement

DLAR 1000.22 requires DLA to facilitate coordination with Federal, state, and local officials and 

organizations that could be affected by a proposed action. DLA invites all agencies and the public with 

an interest in the Proposed Action and alternatives to participate in this NEPA process, which will provide 

DLA with the opportunity to coordinate with and consider the views of other agencies and individuals. A 

premise of NEPA is that the quality of Federal decisions will be enhanced if proponents provide 

information to the public and involve the public in the planning process.

2.0 PROPOSED ACTION AND ALTERNATIVES DESCRIPTION

2.1 Proposed Action

DLA proposes to implement the installation’s RPMP and its component plans. The RPMP provides the 

direction for the future development of the installation over the next 20 to 30 years and identifies potential 

projects that would ensure the installation is able to meet its current and future mission requirements in a 

sustainable and environmentally conscious manner. 

2.1.1 Real Property Master Plan

The RPMP is intended to be the starting point for all programming, design, and construction decisions 

that support the long-range needs of the installation. The primary aspects of the RPMP include the vision, 

goals, objectives, Future Land Use Plan, Capital Investment Strategy, and Future Development Plan. 

Vision: To sustain the best eastern continental U.S. distribution point in support of DLA’s mission to 

provide effective and efficient worldwide support that is warfighter-focused, globally responsive, and 

demonstrates fiscally responsible supply-chain leadership.

Goals: The following eight goals were developed from the planning vision: (1) provide responsive stateof-the-art logistical facilities; (2) sustain and improve installation infrastructure; (3) preserve and 

investigate land use options; (4) create business and community neighborhoods with high-performing 

buildings; (5) lead in energy conservation, efficiency, and sustainability practices; (6) maintain RPMP 

policies, procedures, and tools; (7) develop a sustainable workforce; and (8) implement the remaining

goals and objectives of the SP.

Objectives: Each goal has one or more objectives that are to be implemented to support it. 

Future Land Use Plan: Examination of environmental and operational considerations, land use patterns, 

functional areas, and spatial relationships led to the development of a Future Land Use Plan 

(see Figure 2.1), which identifies the areas most suitable for growth and development and the areas most 

suitable for preservation. The Future Land Use Plan is the optimal organization of real property to allow 

the installation to operate most efficiently. It consolidates land uses, minimizes land conflicts, expands 

the industrial land use, and adds an antiterrorism/force protection (AT/FP) land use category.

Capital Investment Strategy: The Capital Investment Strategy weighs the options for realizing a balance 

between existing and required facilities against a variety of criteria to create a prioritized list of projects.

Future Development Plan: The Future Development Plan is the culmination of the vision, goals, 

objectives, and strategies, prioritized into a series of action plans (i.e., projects). The Future Development 

Plan is the implementation tool for the RPMP. Future Development Plan (Phase I) identifies 19 Military 

Construction (MILCON) projects (see Table 2.1) and 62 Sustainment, Restoration, and Modernization 

projects (see Appendix A) necessary to support the installation’s mission and goals, particularly with 

respect to warehouse space. The Future Development Plan (Phase II) identifies five transportation-related 

MILCON projects that the installation may address once the immediate concerns of facilities and 

infrastructure are met. 

Table 2.1 identifies the Future Development Plan MILCON projects. The projects noted in Table 2.1 are 

identified on Figures 2.2 and 2.3 using the Project Reference Letter found within the left hand column of 

the table. The proposed construction projects would be designed to meet Leadership in Energy and 

Environmental Design (LEED) Silver certification and include sustainable design concepts such as 

transpired solar collectors, radiant floor heating, and other strategies to reduce energy demand, increase 

water efficiency, and improve indoor environmental quality. Energy conservation efforts and sustainable 

principles such as life-cycle, cost-effective practices; green infrastructure/low-impact development (LID);

and Energy Policy Act of 2005 features would be integrated into the proposed construction projects.

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

Implementing the projects in the RPMP would replace undersized and outdated buildings and 

infrastructure with modern, energy-efficient, sustainable buildings and infrastructure. The proposed 

projects include the construction of 4,201,966 square feet (ft2

) of buildings and the demolition of 

2,503,790 ft2 of buildings, which would result in an increase in impervious surface and parking spaces

(DLA 2013a). Additionally, the proposed projects include a transit and non-motorized transportation 

system consisting of two transit hubs; multiple bus stops; a variety of bus, pedestrian, and bicycle routes; 

and rail access to reduce truck conveyance.

2.1.2 Net-Zero Energy Plan

The NZEP balances the installation’s future energy demand from buildings, industrial processes, fleet 

vehicles, and equipment with onsite and offsite renewable energy production. It provides a framework 

for the installation to develop a strategy to meet the applicable Federal mandates for sustainability, energy 

reduction, alternative energy and fuels, and systems integration. The NZEP includes energy reduction 

and fleet management recommendations and renewable energy projects through Fiscal Year 2040. The 

renewable energy projects include transpired solar collectors, a biomass power plant, and a solar 

photovoltaic project. One option in the Net-Zero Energy Plan includes siting the biomass power plant 

and a solar photovoltaic project at Defense Distribution Depot, San Joaquin to meet Defense Distribution 

Center, Susquehanna’s renewable energy goals. The proposed projects include building energyconservation measures, fleet vehicle reductions and replacements, equipment reductions and 

replacements, renewable energy development, microgrid development, and a measurement and 

verification program (see Appendix A). Implementation of the NZEP recommendations would result in 

energy reduction, fossil fuel reduction, and an increase in alternative fuel use; and would enable the 

installation to achieve a net-zero energy footprint (DLA 2013c).

2.1.3 Sustainability Plan

The SP provides a pathway for the installation to move toward compliance with relevant Federal 

mandates regarding sustainability. The SP identifies goals, objectives, and action plans that provide a 

strategy to meet the sustainability goals of the installation within the constraints of available staff and 

funding. The action plans cover several components of sustainability, including energy, renewable 

energy, water, waste, fossil and alternative fuels, high-performance buildings, indoor air quality, 

greenhouse gases, utility resilience and security, transportation, environmental management system, 

community planning, and measurement and verification (see Appendix A). Each action plan is tied to at 

least one of the goals or objectives and provides a quantifiable step in the overall sustainability program. 

The action plans are prioritized via a Capital Investment Strategy that leads to an Implementation Plan for

the next 40 years. Implementation of the SP would allow the installation to increase its sustainability and 

meet or exceed relevant Federal sustainability mandates (DLA 2013b).

2.1.4 Integrated Natural Resources Management Plan

The INRMP is the installation’s plan for managing its natural resources while ensuring the success of the 

military mission. It uses the concept of adaptive ecosystem management to maintain sustainable land use 

on the installation. The INRMP includes 31 proposed projects in the areas of ecosystem management; 

threatened and endangered species and species of concern; wetlands and waters of the United States; 

watershed management; fish and wildlife management; habitat management; exotic and invasive species 

management; grounds maintenance; natural resources law enforcement; outdoor recreation; and 

environmental awareness, education, and outreach (see Appendix A). These projects ensure minimal 

impact on the military mission while providing for the management and stewardship of natural resources 

and the conservation and enhancement of existing ecosystems on the installation. Implementation of the 

INRMP would support the DLA’s continuing need to ensure the safety and efficiency of its mission while 
12

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

practicing sound natural resources stewardship and complying with environmental policies and 

regulations (DLA 2013d).

2.1.5 Integrated Pest Management Plan

The IPMP is the installation’s plan for its pest management program. It provides a sustainable approach 

to managing pests on the installation by using a combination of biological, cultural, physical, and 

chemical tools in a way that minimizes economic, health, and environmental risks. The IPMP describes 

past and anticipated pests and outlines the resources necessary for surveillance and control of these pests 

including any administrative, safety, or environmental requirements. Nonchemical pest-control efforts 

are proposed to be used to the maximum extent possible prior to the application of pesticides. The IPMP

includes pest management outlines that provide the methodology for the appropriate implementation of 

pest-control procedures for each identified pest type, a pesticide use proposal that identifies each pesticide 

proposed, and a 5-year plan for the administrative elements of the pest management program (see 

Appendix A). Implementation of the IPMP would reduce reliance on pesticides; enhance environmental 

protection; and help ensure pests don’t interfere with the military mission, lower morale, damage real 

property, increase maintenance costs, or expose personnel to disease (DLA 2011a).

2.2 No Action Alternative

Under the No Action Alternative, DLA would not implement the RPMP or its component plans. In 

general, implementation of the No Action Alternative would require that the DLA continue to use the 

existing outdated, undersized, and inefficient facilities and abandon the proposed infrastructure 

enhancements, sustainability improvements, and natural resources projects of the component plans, which 

would hamper the ability of the installation to meet its current and future mission requirements. The 

No Action Alternative would not meet the purpose of and need for the action, as described in Section 1.2.

2.3 Alternatives Considered, Including Those Eliminated from Detailed Analysis

The RPMP included an evaluation of three alternatives (i.e., Alternatives A, B, and C) for consideration

as the initial plan for land use at the installation. The three alternatives to development entail varying 

degrees of land use changes to accommodate future projects. Alternative A was selected as the preferred 

initial plan based on several criteria (e.g., mission, DLA initiatives, real property goals and objectives, 

security, infrastructure, and sustainability). Installation critical functions and sustainable practices were 

applied against Alternative A to create the Future Development Plan, which is the basis for the project 

locations and transportation-related MILCON projects in Future Development Plan (Phase II) presented 

in the RPMP. Alternatives B and C do not include project locations and would result in different 

transportation-related MILCON projects for Future Development Plan (Phase II) and substantial 

redevelopment and changes to land use areas. Consequently, Alternatives B and C are not fully fledged 

alternatives to the Future Development Plan and will not be analyzed in this EA.

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

3.0 AFFECTED ENVIRONMENT AND ENVIRONMENTAL 

CONSEQUENCES

All environmental resource areas were initially evaluated for potential consequences. The initial 

evaluation determined that some environmental resource areas would not be impacted or would have 

clearly insignificant impacts. These environmental resource areas were not analyzed in detail in this EA, 

and they are described as follows.

■ Socioeconomics and Environmental Justice. The Proposed Action would not affect areas

outside of DLA-permitted land. It would not include hiring workers in the local labor force, and 

would not result in any outside workers moving to the area. There would be no change in the 

number of installation personnel, area population, or demand for housing and public/social 

services. The Proposed Action would not affect minority or low-income populations because 

implementation of the RPMP and its component plans would be limited to the installation.

■ Cultural Resources. The Proposed Action would have no effect on any archaeological or 

architectural resources listed in or eligible for listing in the National Register of Historic Places 

(NRHP). There are no architectural resources at the installation that are listed or eligible for 

listing in the NRHP. Only one archaeological site at the installation has been determined eligible 

for listing in the NRHP, archaeological site 36YO0337. This resource, designated as being off 

limits for any activity apart from mowing, is located more than 1,400 feet outside of any of the 

proposed projects that would include ground disturbance. 

■ A portion of the adjacent Capital City Airport was determined eligible for listing in the NRHP. 

The closest areas of the installation from the historic-age terminal and hangars at the Capital City 

Airport are more than 2,000 feet distance. The installation has been characterized by warehouses, 

administrative buildings, and associated infrastructure since 1917. Therefore, based on the 

distance and the historic use of the installation, the siting and design of warehouses and other 

structures associated with the Proposed Action would have no effect on the NRHP-eligible 

historic district at the Capital City Airport. Additionally, the Proposed Action would have no 

effect on any modern sites of cultural significance to the community.

■ Health and Safety. The Proposed Action would result in beneficial effects on health and safety 

from incorporation of current design standards and AT/FP criteria, addition of the AT/FP land use 

category along the installation boundary, consolidating administrative functions, and reductions 

in vehicle traffic due to several proposed transportation projects. 

■ Coastal Zone Management. The Proposed Action would not be sited within a coastal zone, nor 

would it impact a coastal zone. 

■ Visual and Aesthetic Resources. The Proposed Action would not involve any activities that 

would result in long-term changes to the aesthetic qualities of the area or landscape. The new 

facilities would follow the design guidelines in the Installation Design Guide, which is being 

updated. This guidance would ensure a consistent and coherent architectural character 

throughout the installation. Landscaping would be used to provide an attractive and professionallooking installation by using plants, shrubs, and trees to blend with the surrounding environment. 

The initial evaluation also determined that there was the potential for significant effects on other 

environmental resource areas; therefore, these environmental resource areas were analyzed in detail in 

this EA. The detailed analysis in this EA determined that significant effects from the Proposed Action 

and No Action Alternative would not occur. The following sections break down by resource area the 

non-significant effects that would result from implementation of the Proposed Action.

3.1 Airspace Management and Safety

3.1.1 Existing Conditions

In compliance with the Federal Aviation Administration’s Airport Design Regulations, each airport must 

have Runway Safety Areas (RSAs), Obstacle Free Zones (OFZs), and Runway Protection Zones (RPZs). 

A RSA is a defined surface surrounding the runway prepared for reducing the risk of damage to airplanes

in the event of an undershoot, overshoot, or excursion from the runway. An OFZ is the airspace below 

150 feet above the established airport elevation and along the runway and extended runway centerline that 

is required to be clear of all objects to provide clearance protection for aircraft landing or taking off from 

the runway, and for missed approaches. RPZs are trapezoidal areas at ground level that begin 200 feet 

beyond the end of the runway area usable for takeoff and landing. These areas are used to enhance the 

safety and protection of people and property on the ground. It is the responsibility of the airport owner to 

protect the RSAs, OFZs, and RPZs from obstructions and incompatible land uses (U.S. DOT/FAA 2012). 

Also associated with RSAs and RPZs are the approach slopes, which are the paths that airplanes follow in 

their final approach and landing. 

The Capital City Airport is adjacent to the northwestern boundary of the installation. The airport 

maintains two asphalt runways: Runway 08/26 and Runway 12/30 (DLA 2013a). Currently, only the 

RPZs and approach slopes for Runway 12/30 and Runway 08/26 extend onto the installation. The 

approach slopes adjacent to the RPZs rise at a 20:1 slope beginning 200 feet past the end of the runways. 

Warehouses 5 and 6, Buildings 12 and 14, and several poles are within the RPZ for Runway 12/30, but no 

facilities and structures are within the approach slope. These facilities and structures are considered to be 

obstructions by the Capital City Airport and, therefore, are equipped with obstruction lights. There are no 

facilities or structures on the installation within the RPZs or approach slopes for Runway 08/26 

(DLA 2013a).

3.1.2 Environmental Consequences

Proposed Action

Long-term, minor, beneficial effects on airspace management and safety would occur. Future action by 

the Capital City Airport might include an updated approach surface for its runways that would have a 

slope of 34:1 based on the requirements outlined in the Federal Aviation Administration’s Airport Design 

Advisory Circular (U.S. DOT/FAA 2012). Due to the proximity of Warehouses 5 and 6 to Runway 

12/30, these buildings would not be in compliance with the updated approach surface. The RPMP 

proposes replacing Warehouses 5 and 6 with a new General Purpose Warehouse (Building 734). Based 

on an anticipated height of approximately 20 feet, the proposed warehouse would be sited approximately 

600 feet from the west end of the existing warehouses. This siting would be outside of the modified 

approach surface (DLA 2013a). The RPMP also proposes to replace Buildings 12 and 14 with a new 

Communications Building (Building 2055), which would be outside of the RPZ for Runway 12/30. 

Lastly, implementation of effective wildlife management strategies in the INRMP would minimize the 

Bird/Wildlife Aircraft Strike Hazard risk for the Capital City Airport.

No Action Alternative

Existing conditions would remain the same as described in Section 3.1.1. Therefore, no effects on 

airspace management and safety would occur.

3.2 Land Use and Recreation

3.2.1 Existing Conditions

Land Use. Land use categories on the installation include Industrial (48 percent), Environmentally 

Sensitive Area (23 percent), Community (14 percent), Professional/Institutional (10 percent), Residential 

(4 percent), and Ranges & Training (less than 1 percent) (DLA 2013a). The general layout of the 

installation includes a large swath of Environmentally Sensitive Area along the southernmost boundary, 

followed by the Industrial zone through the central portion, and Community areas to the north. 

Interspersed within these three main areas are pockets of differing land uses with varying compatibility. 

Incompatible neighboring land uses currently on the installation include Residential and Industrial, 

Community and Industrial, Community and Ranges & Training, and Professional/Institutional and 

Ranges & Training (DLA 2013a). Incompatibility between specific installation land uses and adjacent 

off-installation areas include Community and Residential land use areas near the Capital City Airport. 

Currently, there are 14 distinct land use areas in existence on the installation and eight instances of 

incompatible land use boundary interfaces. The two Residential land use areas lie within the Community 

land use area, with the southernmost Residential land use area adjacent to an Industrial land use area. 

There are four distinct areas of Professional/Institutional, two of which are located within the main 

Industrial land use area. The other two are located within the Community land use area, adjacent to 

Residential land use areas. Two small Industrial land use areas are located apart from the main Industrial 

land use area, and border Community and Professional/Institutional land use areas. Two Ranges & 

Training land use areas occur along the eastern border of the installation, with the southernmost being 

adjacent to the Environmentally Sensitive Area land use area and the northernmost occurring at an 

interface of Industrial, Community, and Professional/Institutional land use areas (DLA 2013a). 

Recreation. Recreational opportunities on the installation include a fitness center, bowling alley, outdoor 

pool, baseball field, picnic area, walking/jogging path, fishing, and a golf course (i.e., Riverview Golf 

Course) with club house (DLA 2013a).

3.2.2 Environmental Consequences

Proposed Action

Land Use. Long-term, moderate, beneficial effects on land use would be expected. Implementation of 

the Future Land Use Plan (see Figure 2.1) would retain the six existing land use categories, but would 

consolidate land uses, minimize land use conflicts, expand the Industrial land use area, and add an AT/FP 

land use category around the perimeter of the installation. The projects in the RPMP and its component 

plans would be sited in appropriate land use areas in accordance with the Future Land Use Plan.

Under the RPMP, there would be a reduction in land use area fragmentation, compatible adjacent land use 

areas would be retained, and land use across the installation would become more cohesive, which would 

add greater functionality. The 14 distinct land use areas would be consolidated to 11 distinct land use 

areas. Most notably, the Professional/Institutional land use category, which is currently fragmented into 

four areas, would be consolidated into a single area. Implementation of the RPMP would maintain the 

proximity of Residential and Community land uses because adjacent Residential and Community land 

areas are not only acceptable, the close relationship of these two land uses is preferable. Incompatible 

land use boundary interfaces would be reduced from eight instances to six, with contact between 

Community and Industrial, and Community and Ranges & Training composing the remaining 

incompatible interfaces. The relationships between the three main areas of the installation would be 

largely unchanged.

Implementation of the RPMP would result in siting of land uses in a manner that fully considers the 

existing conditions and constraints of the installation to support current missions effectively while also 
16

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

making the installation a more functional, easily navigable, and aesthetically pleasing place to work and 

live. 

Changes in building sizes, types, and purposes coupled with the consolidation of buildings of similar 

purpose accompanying the proposed land use area streamlining would enable implementation of measures 

proposed in the NZEP and the SP. For example, new construction techniques, retrofitting initiatives, and 

metering individual buildings would help curb energy usage, enable energy audits, support the creation of 

energy use baselines, and ultimately support the ability to demonstrate that energy-reduction mandates 

would be met. Consolidation of core buildings supports the concept of establishing districts by function 

and purpose, and supports the feasibility of establishing a micro-grid concept in future years.

Implementation of the INRMP would result in greater guidance on the overall land use management 

objective and land use patterns would be enhanced through scrub and food plots and more suitable habitat 

for native species.

Recreation. Short-term, negligible, adverse and long-term, minor, beneficial effects on recreation would 

be expected. Implementation of the RPMP would retain the existing recreational opportunities within the 

installation; however, portions of the fairway and green for Hole 9 of the golf course would be altered 

slightly to accommodate construction associated with the proposed Headquarters Facility. Siting fitness 

trails within the AT/FP standoff along the installation boundary and pedestrian and bicycle networks 

between transit hubs, bus stops, and installation facilities would result in improved employee access to 

recreational facilities. Implementation of the INRMP would result in a basis to develop an aquatic habitat 

management program and establish limited-use buffers around water bodies, which would provide 

protection to aquatic habitats on the installation that are used for fishing.

No Action Alternative

Existing conditions would remain the same as described in Section 3.2.1. Therefore, no effects on land 

use and recreation would occur.

3.3 Noise

3.3.1 Existing Conditions

The ambient noise environment at the installation is affected primarily by aircraft noise and automobile, 

truck, and rail traffic. Given these sources, the ambient noise environment on the installation resembles 

an industrial setting. Typical daytime ambient noise levels in industrial areas are approximately 

67 A-weighted decibels (Engineering Tool Box 2014).

Noise contours have not been completed for the Capital City Airport (DLA 2013a); however, based on

the locations of the runways, it is assumed that some areas of the installation are within the airport’s noise 

contours.

3.3.2 Environmental Consequences

Proposed Action

Long-term, minor, beneficial effects on the noise environment would be expected. The RPMP provides a 

Future Development Plan for the installation that includes design and siting features to reduce noise levels 

from future development. It is proposed that a small portion of land currently designated as residential 

would be modified for industrial use over the next 10 to 20 years for parking in the adjacent industrial 

area. This modification might increase noise in the existing residential areas; however, tree planting 

would be used as a noise buffer along specific areas to screen industrial areas from surrounding sensitive 

land uses. 
17

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

No Action Alternative

Existing conditions would remain as described in Section 3.3.1. Therefore, no effects on noise would 

occur. 

3.4 Air Quality

3.4.1 Existing Conditions

York County has been designated by the U.S. Environmental Protection Agency (USEPA) as 

unclassified/attainment for the following criteria pollutants: carbon monoxide, nitrogen dioxide, sulfur 

dioxide, particulate matter equal to or less than 10 microns in diameter, and lead. Particulate matter equal 

to or less than 2.5 microns in diameter is designated as nonattainment, and 8-hour ozone is designated as 

maintenance (formerly a Subpart 1 ozone nonattainment area) (USEPA 2013a).

The installation has a Title V operating permit (No. 67-05041). Air emissions from the installation are 

primarily produced from the burning of fuel oil No. 2 for heat and hot water, emergency generators, 

degreasing stations, and woodworking operations. The majority of the installation’s air emissions come 

from the operation of the Central Heat Plant (PADEP 2010).

3.4.2 Environmental Consequences

Proposed Action

Long-term, minor, beneficial effects on air quality would occur. While full implementation of the RPMP 

would result in a net increase in building space at the installation, the RPMP would replace older and 

outdated buildings with modern, energy-efficient, sustainable buildings, which would translate into a 

potential reduction in air emissions. The RPMP encourages the future development of the installation 

around transit and non-motorized transportation systems. This type of development would reduce 

potential air emissions by discouraging personnel from driving to destinations and encouraging 

pedestrian, bicycle, and transit movement.

The NZEP and SP aim to reduce the amount of fossil fuel-based energy consumed at the installation and 

achieve a net-zero energy footprint. The NZEP and SP identify numerous actions such as reducing 

energy consumption, initiating fleet management strategies, and increasing reliance on renewable energy 

sources to accomplish these goals. Therefore, the implementation of the NZEP and SP would reduce 

fossil fuel energy consumption, which would reduce the amount of air emissions produced by the 

installation. Other action plans in the SP take aim at improving indoor air quality and reducing 

greenhouse gases.

No Action Alternative

Existing conditions would remain the same as described in Section 3.4.1. Therefore, no effects on air 

quality would occur.

3.5 Geological Resources

3.5.1 Existing Conditions

Geology. The installation straddles two major physiographic provinces. The northwestern 25 percent of 

the installation lies within the Great Valley section of the Appalachian Valley and Ridge physiographic 

province. The Great Valley section is wide, fertile lowland with minimal topographic relief and is 

primarily underlain with interbedded light-gray limestone and gray dolomite of the Epler Formation. The 

southeastern 75 percent of the installation lies within the Triassic Lowlands of the Piedmont 
18

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

physiographic province, which is characterized by more relief and is underlain by red to brownish-red 

siltstone and shale with thin sandstone interbeds of the Gettysburg Formation. The boundary between the 

Epler and Gettysburg formations is defined by an unnamed fault (DLA 2007a, PA DCNR 2011, 

USGS 2014). 

Topography. The area surrounding the installation is rolling to moderately hilly. Within the boundaries 

of the installation, the terrain contains slopes of less than 10 percent, trending toward the north and south 

away from the higher central administration and warehouse areas. The areas along the southeastern and 

southern boundaries of the installation are swampy lowlands that contain Marsh Run Pond and Creek. 

Escarpments along the Susquehanna River abruptly rise between 20 and 80 feet above the river’s surface. 

The developed portions of the installation have been graded to accommodate past and current 

development (DLA 2007a).

Elevations at the installation range from approximately 300 feet above mean sea level (msl) along the 

Susquehanna River to 385 feet above msl in the central portions of the installation (USGS 2013).

Soils. Due to its highly urbanized landscape, much of the soil at the installation has been designated by 

the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS) as “Urban land” 

(USDA-NRCS 2014). This designation means that natural soil structure largely has been eliminated due 

to widespread man-made development and impervious surfaces. The NRCS does not provide a 

characteristics or engineering limitations summary for Urban land soil. Examination and identification of 

soils or soil-like materials in this mapping unit is impractical. Detailed onsite characterizations are 

necessary to determine potential uses and limitations of this mapping unit. 

The only areas of natural soil structure remaining at the installation are found in areas with development 

restrictions in the southeast corner of the installation where the Bowmansville silt loam, Rowland silt 

loam, and the Penn silt loam, 3 to 8 percent slopes have been mapped (DLA 2007a). The Bowmansville 

and Penn soils are classified as farmland of statewide importance, while the Rowland soils are classified 

as prime farmland but not of statewide importance (USDA-NRCS 2014). 

Geologic Hazards. The U.S. Geological Survey has classified the area associated with the installation as 

having a low potential for earthquake hazards. The region of the installation has a seismic hazard rating 

of approximately 8 to 16 percent gravity, meaning little or moderate damage to buildings would be 

expected during an earthquake that has a 2 percent chance of occurring during a 50-year period 

(USGS 2008). The fault zone associated with the boundary between the Epler and Gettysburg formations 

crosses the northern portion of the installation (see Figure 3.1).

3.5.2 Environmental Consequences

Proposed Action

Geology. No effects on geology would be expected. No unique geological features or regional lithology, 

stratigraphy, or geological structure would be impacted by the Proposed Action.

Topography. Long-term, negligible, adverse effects on topography would occur. The proposed projects 

in the RPMP, NZEP, and SP would be in developed areas; therefore, minimal change in topography 

would be expected. Implementation of the IPMP and INRMP would occur throughout the installation but 

have no effect on topography because these projects would have little to no ground disturbance.

Soils. Long-term, minor, adverse effects on soils would be expected from implementation of the RPMP, 

NZEP, SP, and IPMP. All of these projects would be in areas underlain by Urban land soils, which have 

already been disturbed by previous activities. No designated farmland of statewide importance or prime 

farmland soils are within these proposed project areas. The timing of the projects, use of Best 

Management Practices (BMPs), and incorporation of soil erosion- and sediment-control measures into site 

plans would assist in limiting erosion and sediment production.
19

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

Figure 3.1 Geological Hazards, Surface Waters, Floodplains, and Wetlands
20

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

Long-term, minor, beneficial effects on soils would result from implementation of the INRMP. The 

INRMP includes a soil erosion and sedimentation program, monitoring of soil conditions to identify 

potential problem areas, soil conservation measures for exposed soils, and avoidance of activities likely to 

result in soil erosion, all of which would result in reduced impacts on soils and reduce soil erosion at the 

installation. Soil disturbance can be mitigated through timely seeding and revegetation.

Geologic Hazards. Long-term, minor, adverse effects could occur. Adverse effects on humans and 

property could occur as a result of differential settling of structures constructed over the unnamed fault 

that extends across the northern portion of the installation. Project A, New Headquarters Facility, of the 

RPMP would be sited adjacent to this fault. The seismic hazard rating in this area is very low; therefore, 

tectonic movement of the fault is not expected.

No Action Alternative

Existing conditions would remain the same as described in Section 3.5.1. Therefore, no effects on 

geological resources would occur. 

3.6 Water Resources

3.6.1 Existing Conditions

Surface Water. The Susquehanna River and Marsh Run Creek are the primary surface water features at 

and near the installation. The installation is bordered to the north and to the east by the Susquehanna 

River. Marsh Run Creek flows parallel to the southern boundary of the installation before discharging

into the Susquehanna River. A section of Marsh Run Creek within the installation boundary was dammed 

by the U.S. Army Corps of Engineers in the 1960s, forming Marsh Run Pond. Most surface water at the 

installation drains from the higher elevations in the center of the installation to Marsh Run Creek and 

Pond; however, the northern cantonment area drains to the north and east directly into the Susquehanna 

River. Figure 3.1 illustrates the locations of surface water at and near the installation.

The installation has two National Pollutant Discharge Elimination System (NPDES) permits: one 

associated with the treated effluent from the wastewater treatment plant (WWTP) and one for storm 

water. Treated effluent from the WWTP is discharged to the Susquehanna River. The existing WWTP is 

not able to conform to pending Pennsylvania Department of Environmental Protection (PADEP) 

Chesapeake Bay Tributary Strategy nutrient reduction discharge limit requirements. Storm water for the 

installation is discharged to the Susquehanna River and Marsh Run (DLA 2007b).

Groundwater. The installation overlies the Valley and Ridge aquifer, which is not a sole-source aquifer 

for the region. Groundwater flow moves radially away from a recharge area located in the northeastern

portion of the installation. Groundwater flow is toward the Susquehanna River in the north and east

portions of the installation, toward Marsh Run Creek in the south and southwestern portions of the 

installation, and toward Yellow Breeches Creek in the western portions of the installation. Depth to 

groundwater ranges from less than 1 foot below ground surface in the vicinity of Marsh Run Creek to 

approximately 30 feet below ground surface in the administration area (DLA 2013e).

Past releases of hazardous substances have resulted in areas of groundwater contamination within and 

adjacent to the installation. Groundwater contamination is monitored and evaluated across the installation 

via approximately 120 monitoring wells. The majority of the installation is within groundwater use 

restriction areas. The groundwater use restrictions are associated with several Installation Restoration 

Program (IRP) sites where groundwater contamination has been confirmed; however, all of the IRP sites 

are closed and under no further action status. The institutional controls are implemented to prevent the 

potential future use of groundwater for potable purposes. 
21

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

Floodplains. Approximately 3 acres in the southwestern portion of the installation are located within the 

100-year floodplain. Figure 3.1 illustrates the 100-year floodplain areas on the installation.

3.6.2 Environmental Consequences

Proposed Action

Surface Water. Long-term, minor, beneficial effects on surface water would be expected. The overall 

increase in impervious surface proposed under the RPMP would result in increased storm water runoff, 

which could adversely affect surface water. However, the increased runoff would be managed through 

the implementation of storm water initiatives presented in the SP, such as rainwater harvesting, storm 

water capture ponds, and rain gardens (DLA 2013b). Furthermore, LID features would be used to adhere 

to Section 438 of the Energy Independence and Security Act (EISA) so that post-development hydrology 

would be equal to or less than pre-development hydrology to the extent technically feasible. Reduction in 

storm water volume and overland flow would result in offsetting effects for installation and local surface 

waters.

The proposed WWTP would be designed to comply with PADEP Chesapeake Bay Tributary Strategy 

nutrient reduction discharge limit and NPDES permit requirements (DLA 2013b), which would improve 

the quality of the effluent discharged to the Susquehanna River. The siting and design of the projects in 

the RPMP would require revisions to the NPDES permits for the WWTP and storm water discharges.

The establishment of riparian buffers, as proposed in the INRMP, would reduce nonpoint source impacts 

associated with runoff and adjacent land uses.

Groundwater. Long-term, minor, adverse effects on groundwater would be expected. The overall 

increase in impervious surface proposed under the RPMP would reduce available acreage for infiltration 

and recharge of groundwater. However, adverse effects from the increase in impervious surface would be 

minimized through the use of LID practices and by employing long-term storm water-control measures 

for groundwater recharge in accordance with Section 438 of EISA. In addition, implementation of 

WTR12, Storm Water Capture Ponds, and WTR13, Rain Gardens as outlined in the SP, would enhance 

percolation and reduce storm water runoff (DLA 2013b). 

The expansion of industrial activity on the installation has the potential for release of hazardous 

substances to groundwater; however, BMPs and use of the Pollution Prevention and Hazardous Waste 

Minimization Plan would prevent any releases from negatively impacting the environment (DLA 2011b).

Floodplains. No effects on floodplains would be expected. The goals of the INRMP include no net loss 

of floodplain acreage, and none of the projects proposed in the RPMP and its component plans would be 

sited within the floodplain.

No Action Alternative

Existing conditions would remain as described in Section 3.6.1. Therefore, no effects on water resources 

would occur.

3.7 Biological Resources

3.7.1 Existing Conditions

Vegetation. The majority of the installation is developed. Undeveloped areas are primarily within the 

southern portion, along Marsh Run Creek, where vegetation consists of deciduous forests and vegetation

associated with wetlands. Vegetation in the developed portions of the installation consists of maintained 

turf grass, shrubs and trees, and plant communities typical of landscaped species (DLA 2009a). 
22

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

Wildlife. Few wildlife species are found on and in the vicinity of the installation, and their habitat is 

limited because the majority of the installation is developed. The remaining undeveloped portions consist 

of water features and second-growth forest. Wildlife species known to occur on the installation generally 

include species that are adapted to human development and activities that impact natural resources 

(DLA 2009a).

Protected Species. Protected species include federally listed species, state-listed species, migratory birds, 

and plant species of concern. Based on informal consultations with the U.S. Fish and Wildlife Service 

(USFWS) and the state agencies during the development of the installation’s INRMP, ellisia (Ellisia 

nyctelea), eastern prickly pear cactus (Opuntia humifusa), and the bog turtle (Glyptemys muhlenbergii) 

have the potential to occur on the installation. Ellisia is state-listed as threatened and eastern prickly pear 

cactus is state-listed as rare. The bog turtle is federally listed threatened and state-listed endangered. 

There is one known bald eagle nest near the installation but given the installation’s proximity to the 

Susquehanna River, additional nests might be present or could appear in the future. Communal roosting 

areas or foraging areas might also exist along the Susquehanna River (USFWS 2012).

Wetlands. There is a total of 95.95 acres of wetlands on the installation. Ten wetland areas measuring 

95.35 acres are on the southern portion of the installation adjacent to Marsh Run Creek (USACE 1998), 

and two wetland areas composing 0.6 acres are adjacent to the intersection of Sixth Street and Marsh Run 

Road. Figure 3.1 illustrates the wetlands on the installation.

3.7.2 Environmental Consequences

Proposed Action

Vegetation. Long-term, minor, beneficial effects on vegetation would be expected. The proposed 

projects in the RPMP would be sited in the developed areas of the installation and are not expected to 

result in a loss of native vegetation. The INRMP projects, such as updating the flora inventory every 3 to 

5 years, daylighting desired trees, and nonnative and invasive plant species eradication, would facilitate 

proper management of installation vegetation. Additional management measures established to protect or 

enhance aquatic and riparian habitats include eradicating invasive and nonnative plant species and 

minimizing erosion and sedimentation. As outlined in the SP, maximizing tree planting and open space 

while minimizing paved surfaces would reduce the heat island effect and enhance natural habitat on the 

installation. 

Wildlife. Long-term, minor, beneficial effects on wildlife species and their habitat would be expected. 

There is a lack of suitable habitat and native wildlife in the areas where the RPMP projects would be 

sited. Several projects described in the INRMP would be implemented to survey or inventory wildlife on 

the installation. Information obtained from these efforts would help installation personnel manage 

wildlife resources. Assessment of wildlife populations at the installation (e.g., birds, small mammals, and 

herptiles) would provide a baseline that can be used in tracking conditions and trends, which would allow 

management practices to be applied where and when needed. 

Protected Species. Long-term, minor, beneficial effects on protected species would be expected. The 

projects identified in the RPMP would be sited in areas that are previously disturbed and developed with 

no suitable habitat for the listed species with the potential to occur on the installation. No projects would 

be sited in bald eagle roosting or foraging areas. As part of the Threatened and Endangered Species

objectives and projects, surveys for sensitive species and migratory bird nests would be conducted. 

Implementation of formal management plans and routine assessments and monitoring of these special 

status species provide protection of these species and a baseline of data that can be used to prioritize 

projects and identify efficient allocation of resources. The IPMP periodically evaluates ongoing and 

proposed pest-control operations to ensure compliance with the Endangered Species Act. 
23

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

No adverse effects on migratory birds would be expected. Due to the lack of natural vegetation and 

surface waters where the RPMP projects would be sited, it is unlikely that migratory birds would use 

these areas as breeding or migratory habitat. 

Wetlands. Long-term, minor, beneficial effects on wetlands would be expected. None of the projects 

identified in the RPMP would be sited within or adjacent to wetlands. The proposed projects would result 

in an increase in impervious surface; however, the resulting increase in run off would not flow directly 

into delineated wetlands. The INRMP projects, such as updating the wetland inventory data and 

monitoring impacts of training activities on wetlands, would provide installation personnel with 

information that would facilitate proper management of wetlands. The IPMP is a guide to reduce reliance 

on pesticides and to enhance environmental protection including measures to avoid sensitive areas 

(i.e., wetlands). 

No Action Alternative

Existing conditions would remain the same as described in Section 3.7.1. Therefore, no effects on 

biological resources would occur. The No Action Alternative does not provide for the formal 

implementation of a routine habitat assessment and monitoring program. The health and condition of the 

wildlife populations would not improve, and management measures to increase the abundance and 

biodiversity of wildlife would not be implemented. In addition, management measures designed to 

protect and enhance wildlife habitats (i.e., aquatic, riparian, wetlands, terrestrial) would not be 

implemented, thereby allowing for a continuing decline in the quality and complexity of the habitats. The 

No Action Alternative does not establish routine management measures to protect and enhance these 

habitats by preventing or minimizing potential impacts.

3.8 Transportation and Infrastructure

3.8.1 Existing Conditions

Transportation System. The installation has three active access control points (ACPs), two for 

automobile traffic (i.e., Posts 1 and 3) and one for trucks (i.e., Post 4). The primary installation roads 

include Mifflin Avenue, Mission Drive, and H Avenue. A parking study performed for the northern 

portion of the installation found that 73 percent of parking spaces were used (DLA 2013f).

Transportation options to and within the installation include privately owned vehicles, city provided 

transit, van pools, school bussing, bicycling, and foot traffic. Approximately 7 percent of employees 

commute to work using car/van pools or public transit. There is no contiguous bicycle/walking route 

within the installation. Currently, the installation has a total of 223 vehicles in the General Services 

Administration fleet and 18 non-tactical vehicles associated with morale, welfare, and recreation 

(DLA 2013a, DLA 2013b).

Electrical System. The installation’s electrical distribution system consists of overhead and underground 

lines that have adequate capacity for the installation’s current and future demand; however, much of the 

system is aged and redundancy is needed for one of the circuits. Generators installed at selected buildings 

allow critical operations to continue during outages (DLA 2013a). In 2012, the installation used 227,320 

million British thermal units (MMBtu) of electrical power (DLA 2013c). 

Natural Gas System. Natural gas service is available only within the northern portion of the installation. 

The current capacity of the natural gas system at the installation is adequate (DLA 2013a). In 2012, the 

installation used 15,186 MMBtu of natural gas (DLA 2013c).

Liquid Fuel System. Fuel oil is used by the Central Heat Plant to provide steam heat to the southern 

portion of the installation. Fuel oil is also used to heat several other buildings within the installation that 

are not connected to the steam heat system. Propane is used in industrial operations, cooking, and to heat 
24

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

some buildings. Gasoline and diesel fuel are used to fuel the installation’s vehicles (DLA 2013b). In 

2012, the installation used 204,015 MMBtu of fuel oil No. 2 and 430 MMBtu of propane. In 2011, the 

installation used 10,148 MMBtu of unleaded gasoline and 15,234 MMBtu of diesel fuel.

Potable Water System. Potable water is delivered to the installation from a treatment plant with 10 

million gallons per day (GPD) of capacity (DLA 2013a). Average annual potable water consumption at 

the installation is approximately 170,000 GPD. The water distribution system at the installation generally 

follows the streets and roads throughout the installation. Pipe materials include cast iron, ductile iron, 

asbestos-cement, and copper. The installation has a 1-million-gallon, potable-water emergency-use 

reservoir at an off-installation location to store water for fire demands and emergency reserves. The 

reservoir and piping are nearly 70 years old (DLA 2013b).

Sanitary Sewer and Wastewater System. The installation operates a sanitary wastewater collection and 

treatment system. The installation’s WWTP is aged. The permitted capacity of the WWTP is 

800,000 GPD; however, the average flow to the WWTP is approximately 100,000 GPD (DLA 2013a). 

The existing WWTP is not able to conform to pending PADEP Chesapeake Bay Tributary Strategy 

nutrient reduction discharge limit requirements. 

Communications System. The telephone and telecommunications network consists of a central office 

and distribution lines. Building 14 serves as the main communications station with Buildings 12 and 54 

serving lesser roles (DLA 2013a). Building 14 is operating under a waiver because it is in the flight path 

of the adjacent Capital City Airport (DLA 2012a).

Solid Waste Management. Solid waste generated at the installation is transported off site and disposed of 

at a landfill. Solid waste is handled in keeping with the installation’s Integrated Contingency Plan, 

incorporating source reduction, reuse, recycling, green procurement, and other appropriate and 

complementary principles to minimize the quantity of solid waste generated (DLA 2011b). 

Storm Water System. Storm water on the installation is managed through a system of catch basins, pipes, 

outfalls, and ponds (DLA 2013b). The storm water drainage system is divided by a ridgeline that runs 

east to west near and along J Avenue. The northern section drains to the Susquehanna River and the 

southern section drains to Marsh Run. Conveyance of the current storm water drainage system has 

proven adequate for the frequency and duration of most storms experienced in the area (DLA 2013a).

3.8.2 Environmental Consequences

Proposed Action

Transportation System. Long-term, moderate, beneficial effects on the transportation system would be 

expected. Transportation infrastructure would be improved with the siting of three new roads proposed in 

the RPMP, and planned improvements of the ACPs. Two roads would connect G and H Avenues and 

connect G Avenue to the golf course to provide greater access to recreational points. The third road 

would run parallel to M and J Avenues to provide an alternate route for vehicles traveling through the 

industrial area from northwest to southeast. The creation of additional parking would result in a net 

increase of 512 parking spaces on the installation (DLA 2013a). The RPMP includes two transit hubs, 

numerous bus stops, and pedestrian and bicycle routes granting improved access to all areas of the 

installation (DLA 2013a). Such improvements would reduce truck and automobile traffic and mitigate 

congestion. Pedestrian and bicycle networks between transit hubs, bus stops, and installation facilities 

would result in improved employee access to recreational facilities. 

Electrical System. Long-term, moderate, beneficial effects on electrical systems would be expected. 

Implementation of the RPMP would result in the addition of approximately 1.7 million ft2 of building 

area, most of which would consist of warehouse space. With this increase in building area, a correlating 

increase in electrical energy demand would be expected. However, implementation of the NZEP and SP 

would result in buildings and infrastructure being designed to maximize efficiency and minimize demand. 
25

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

Additionally, the NZEP guides the installation toward self-sufficiency and positions the installation for 

development of a microgrid, transpired solar collectors, and a biomass plant (DLA 2013c), potentially 

eliminating reliance on the installation’s current commercial utility provider. 

Natural Gas System. Long-term, minor, adverse effects on natural gas would be expected. The increase 

in building area from implementation of the RPMP would result in a correlated increase in heating energy 

requirements. The NZEP indicates that natural gas would eventually become the fuel of choice for 

heating, replacing fuel oil No. 2 and resulting in an increased demand for natural gas. However, 

implementation of the NZEP would result in buildings designed to maximize efficiency and minimize 

demand, partially offsetting the increase in demand for natural gas. 

Liquid Fuel System. Long-term, minor, beneficial effects on liquid fuels would be expected. The NZEP 

indicates that natural gas would eventually become the fuel of choice for heating, replacing fuel oil No. 2. 

Recommendations contained in the NZEP include increased use of propane/electrical powered forklifts; 

decreased use of gasoline-powered forklifts; consideration for alternative fuel vehicles; and optimized 

vehicle fleets. Implementation of these recommendations would result in a decreased demand for fuel oil, 

diesel fuel, and gasoline, and a slight increase in demand for propane. 

Potable Water System. Long-term, moderate, beneficial effects on potable water supply and delivery 

would be expected. The upgraded distribution system would assist in attaining the goals stated in the SP 

to improve water storage while maintaining distribution system integrity and increasing available pressure 

to fire suppression systems. The proposed SP goal of attaining LEED Silver certification on new 

construction would provide a beneficial water consumption decrease over time. RPMP Project F 

proposes to replace the existing ground level reservoir with a new elevated reservoir, which would 

provide a water storage capacity of 750,000 gallons (DLA 2012b, DLA 2013b). The proposed reservoir 

would be secured within the installation’s boundary, which would make it more secure that the current 

reservoir. Actions plans in the SP include water-efficient landscaping plant selection, water-efficient 

irrigation systems, and rooftop water harvesting and cistern collection for toilet flushing and irrigation.

Sanitary Sewer and Wastewater System. Long-term, moderate, beneficial effects on the sanitary sewer 

and wastewater systems would be expected. The RPMP construction projects would incorporate 

sustainable building and planning principles, maximizing efficiency and minimizing demand. 

Additionally, replacing the installation’s WWTP would result in a more efficient and resilient system. 

Actions plans in the SP include water-efficient plumbing fixtures, treated wastewater reuse for irrigation, 

and gray water use for toilet flushing and irrigation.

Communications System. Long-term, moderate, beneficial effects on communications systems would be 

expected. The RPMP includes projects to improve communication facilities and equipment, which would 

result in a more reliable, more secure, and more resilient system. The new communications building 

would be located outside of Capital City Airport’s flight path. Communications infrastructure would be 

incorporated into new facilities, and existing communications capacity would not be exceeded by 

demand. 

Solid Waste Management. Long-term, minor, beneficial effects on solid waste management would be 

expected. The SP includes several action plans that would reduce and improve the management of solid 

waste.

Storm Water System. Long-term, minor, adverse effects on storm water would be expected. 

Implementation of the RPMP would result in increased impervious surface area. However, the increased 

run off would be managed through the implementation of storm water initiatives presented in the SP, such 

as rainwater harvesting, storm water capture ponds, and rain gardens (DLA 2013b). Furthermore, LID 

features would be used to adhere to Section 438 of the EISA so that post-development hydrology would 

be equal to or less than pre-development hydrology to the extent technically feasible.
26

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

No Action Alternative

Existing conditions would remain the same as described in Section 3.8.1. Therefore, no effects on 

transportation and infrastructure would occur.

3.9 Hazardous Materials and Wastes

3.9.1 Existing Conditions

Hazardous Materials, Hazardous Wastes, and Petroleum Products. The installation’s Pollution 

Prevention and Hazardous Waste Minimization Plan addresses required pollution prevention and 

hazardous waste minimization requirements applicable to the installation (DLA 2011b). Buildings 53 and 

87 are the primary hazardous materials storage locations for the installation (DLA 2009b).

Environmental Restoration Program. There are 63 environmental sites (i.e., solid waste management 

units [SWMUs], areas of concern [AOCs], and IRP sites) at the installation. Fifty of the environmental 

sites were determined to require no further action (DLA 2010). The remaining 13 environmental sites 

have been closed; however, groundwater monitoring is being conducted for environmental sites SWMU 

No. 6, SWMU No. 17, SWMU No. 42, AOC N, and IRP site 63; and land use controls are in place due to 

residual soil contamination for environmental sites SWMU No. 17 and AOC N (see Figure 3.2). The 

majority of the southern and central portions of the installation are within groundwater use restriction 

areas due to groundwater contamination. There are no Military Munitions Response Program sites at the 

installation (DLA 2013a, DLA 2013e). 

Asbestos-Containing Material. Facilities constructed prior to 1980 are assumed to contain asbestoscontaining materials (ACMs). Most of the buildings associated with the projects in the RPMP were 

constructed prior to 1980. There are no suspected ACM disposal areas within the installation. 

Lead-Based Paint. The use of most lead-based paint (LBP) was banned in 1978; hence, all buildings 

constructed prior to 1978 are assumed to contain LBP. Most of the buildings associated with the projects 

in the RPMP were constructed prior to 1978. There are no suspected LBP disposal areas within the 

installation.

Polychlorinated Biphenyls. All polychlorinated biphenyl (PCB)-containing transformers have been 

removed from the installation; however, PCB-containing fluorescent light ballasts and other 

PCB-containing equipment might be present within buildings associated with the projects in the RPMP. 

Pesticides. The installation uses an integrated pest management approach to pest control to minimize the 

types and quantities of pesticides used at the installation. Least-toxic chemical controls are used, where 

appropriate. Pesticides at the installation are stored at Building 151. Pesticide application is conducted 

by Pest Management personnel who follow a general policy of evaluating the need for chemical 

application prior to spraying.

Radon. The USEPA rates York County, Pennsylvania, as a Federal Radon Zone 1. Zone 1 counties have 

the highest radon potential and a predicted average indoor radon screening level greater than 4 picoCuries 

per liter (pCi/L) (USEPA 2013b). The USEPA has a guidance radon level of 4 pCi/L in indoor air for 

residences; however, there have been no standards established for commercial structures.

3.9.2 Environmental Consequences

Proposed Action

Hazardous Materials, Hazardous Wastes, and Petroleum Products. Long-term, minor, beneficial 

effects would be expected. As noted in Table 2.1, one new warehouse would replace two or three older 

warehouses; therefore, use, storage, and generation of hazardous substances could be consolidated. 

Building 87, the hazardous materials warehouse, would be upgraded and expanded, which would allow 

for better storage of hazardous materials. Actions in the NZEP and SP would reduce the storage and 

consumption of petroleum products. 

Environmental Restoration Program. No effects on the environmental restoration program would be 

expected. None of the RPMP projects would be sited within areas with land use controls; however, 

several of the RPMP projects would be sited within areas undergoing groundwater monitoring. Proposed 

projects would avoid existing groundwater monitoring wells.

Asbestos-Containing Material. Long-term, minor, beneficial effects would be expected. Implementation 

of the RPMP would remove older buildings, which are more likely to contain ACMs, from the installation 

and replace them with newer buildings, which would be designed to be free of ACMs. The removal of 

ACMs from the installation would be beneficial in that there would be an overall decrease in these 

materials.

Lead-Based Paint. Long-term, minor, beneficial effects would be expected. Implementation of the 

RPMP would replace buildings assumed to contain LBP (i.e., those constructed prior to 1978) with newer 

buildings that would not contain LBP. The removal of LBP would be beneficial in that there would be a 

decrease in these materials on the installation.

Polychlorinated Biphenyls. Long-term, minor, beneficial effects would be expected. Implementation of 

the RPMP would replace buildings that might have PCB-containing equipment with newer buildings that 

would not have PCB-containing equipment. The removal of PCBs would be beneficial in that there 

would be a decrease in these materials on the installation.

Pesticides. Long-term, minor, beneficial effects would be expected. Implementation of the IPMP would 

reduce reliance on pesticides, ensure that pest management equipment is programmed for replacement,

and include the construction of a pesticide mixing and equipment storage hardstand at the golf course 

maintenance shop. 

Radon. No effects from radon would be expected. The installation would use existing radon testing 

information or conduct radon testing to confirm the radon levels at the various project locations. If the 

testing results were to confirm radon at concentrations above 4 pCi/L, the new buildings would be 

designed to include appropriate radon-control infrastructure to limit the potential for indoor radon 

accumulation.

No Action Alternative

Existing conditions would remain the same as described in Section 3.9.1. Therefore, no effects on 

hazardous materials and waste would occur.

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

4.0 CUMULATIVE AND OTHER EFFECTS

4.1 Cumulative Effects

Cumulative effects are the incremental effects of a proposed action when added to the aggregate effects of 

other past, present, and reasonably foreseeable future actions. For this analysis, the temporal span of the 

Proposed Action is 20 to 30 years and the spatial area of consideration is the installation and surrounding 

region. 

For most resource areas, the present effects of past actions are now part of the existing environment 

described in Chapter 3. Identification of projects occurring at and nearby the installation during the 

same time as the Proposed Action ensures that all present and reasonably foreseeable future activities that 

have the potential to result in cumulative effects are taken into account. The present and reasonably 

foreseeable future actions identified for this cumulative effects analysis are the following:

■ Widen Interstate (I)-76 from two to three lanes in each direction between the Susquehanna River 

Bridge and Exit 242.

■ Construct an additional travel lane for northbound I-83 through the interchange with Highway 

581.

■ Construct a 12-inch natural gas pipeline under the Susquehanna River from Steelton, 

Pennsylvania, to the installation to provide natural gas service. The installation would also add 

several smaller natural gas pipes and replace several fuel oil No. 2 burners with dual-fuel burners.

The Proposed Action, when combined with past, present, and reasonably foreseeable future projects, 

would not result in cumulatively significant effects on any resource area. The resource areas that have the 

potential to be cumulatively affected are presented in the paragraphs below. These paragraphs describe 

the non-significant cumulative effects that would occur.

Airspace Management and Safety. Future development at the installation and surrounding region would 

be sited and designed to meet the RSAs, OFZs, RPZs, and approach surfaces of the Capital City Airport. 

Land Use and Recreation. Future development at the installation would be sited and designed according 

to the land use categories in the installation’s RPMP, and future development off-installation would be 

sited and designed according to local zoning and planning regulations. Holes 5, 6, 14, and 15 of the golf 

course would be closed temporarily during the construction period for the natural gas pipeline.

Noise. A temporary cumulative increase in noise would occur from construction, demolition, and landdisturbing activities but would be limited to the areas adjacent to the work areas. Sensitive noise 

receptors, such as homes and schools, are not expected to be affected.

Air Quality. Temporary increases in air emissions would occur from the use of construction equipment. 

Permanent increases in air emissions would occur from new stationary air emissions sources; however, 

the removal of existing stationary air emissions sources would permanently reduce air emissions. 

Geological Resources. Increased erosion and sedimentation during excavation, grading, and filling

would be possible. Adverse effects would be limited because the region surrounding the installation is 

heavily urbanized and most soils have already been disturbed by past activities.

Water Resources. Added impervious surfaces would increase the amount of storm water runoff and 

reduce the amount of surface area available for groundwater recharge. LID and storm water management 

techniques would be implemented to minimize storm water runoff.

Biological Resources. Cumulative effects on vegetation, wildlife, and protected species would be limited 

due to the highly urbanized area and the minimal amount of vegetation, wildlife habitat, and habitat

capable of supporting protected species surrounding the installation.
30

DEFENSE DISTRIBUTION CENTER, SUSQUEHANNA | ENVIRONMENTAL ASSESSMENT

Transportation and Infrastructure. Widening portions of I-76 and I-83 would improve traffic flow, 

alleviate traffic congestion, and improve transportation infrastructure throughout the region. Expansion 

of natural gas service to the installation would provide another source of energy for the installation.

Hazardous Materials and Wastes. Construction activities would result in a temporary increase in the

generation of hazardous wastes. Reductions in the amount of fuel oil No. 2 used at the installation would 

also occur due to the change to natural gas as the primary fuel for the Central Heat Plant.

4.2 Unavoidable Adverse Effects

Unavoidable adverse effects would occur if the Proposed Action was implemented. Adverse effects that 

potentially could not be avoided include temporary disruptions to Hole 9 of the golf course, the potential 

for differential settling of structures sited adjacent to the fault line, disturbance of topographic and soil 

characteristics, increased storm water runoff and reduced groundwater infiltration from the added 

impervious surface, and increased natural gas consumption. Each of these effects is discussed in detail in 

Sections 3.1 through 3.9. None of these effects would be significant.

4.3 Compatibility of the Proposed Action and Alternatives with the Objectives of 

Federal, Regional, State, and Local Land Use Plans, Policies, and Controls

Implementation of the installation’s RPMP and its component plans would not result in any significant or 

incompatible land use changes on- or off-installation. The RPMP and its component plans consider the 

installation’s existing conditions and constraints in the siting, design, and timing of the projects proposed 

within these plans. The Proposed Action would not conflict with designated RSAs, OFZs, RPZs, and 

approach surfaces of the Capital City Airport or any applicable off-installation land use ordinances.

4.4 Relationship Between Short-term Uses of Man’s Environment and Maintenance 

and Enhancement of Long-term Productivity

The short-term effects of the Proposed Action include disruptions to Hole 9 of the golf course. Long-term 

effects include siting proposed facilities in accordance with the latest air space and land use regulations, 

encouraging the use of alternative forms of transportation, implementing sustainability actions to reduce 

energy consumption, modernizing utility infrastructure, and establishing appropriate natural resources

management processes.

4.5 Irreversible and Irretrievable Commitment of Resources

The Proposed Action would not involve the irreversible and irretrievable commitment of energy resources 

and human resources. The Proposed Action would result in the commitment of land for the siting of the 

future proposed facilities. The effects of this commitment would be permanent but not significant.

4.6 Energy Requirements and Conservation Potential

The Proposed Action would not involve the direct consumption of energy. The Proposed Action would 

increase energy consumption from the net increase in building space, but it would also reduce energy 

consumption by replacing older and outdated buildings with modern, energy-efficient, sustainable 

buildings. The installation’s NZEP and SP would reduce the amount of energy consumed at the 

installation and encourage the use of energy from renewable, non-fossil-fuel-based sources. The 

installation would achieve a net-zero energy footprint after full implementation of the NZEP in 20 to 

30 years. 

4.7 Natural or Depletable Resource Requirements and Conservation Potential

The Proposed Action would require no significant use of natural or depletable resources.

5.0 CONCLUSION

The introduction to Section 3 provides information on which resource areas were selected to be analyzed 

in detail in the EA and the rationale behind each decision. Table 5.1 summarizes the potential impacts of 

the Proposed Action and the No Action Alternative on the environmental resource areas analyzed in 

detail. Implementation of the Proposed Action or No Action Alternative would not result in any 

individual or cumulatively significant environmental impacts. Therefore, preparation of an EIS is not 

warranted and issuance of a FONSI would be appropriate.
