(2) Site Maps
(3) Applicable Conditions
1. In response to reference (a) , this document satisfies the National
Environmental Policy Act (NEPA) review requirement under reference (b) and
qualifies as a categorical exclusion in compliance with 32 C.F.R. 775.6 (f)
(35) , which states:
(35) Demolition, disposal, or improvements involving buildings or
structures when done in accordance with applicable regulations including
those regulations applying to removal of asbestos, PCBs, and other
hazardous materials.
RATIONALE
This project will not result in an extraordinary circumstance.
2. The project proposes the following scope as provided by the Action
Sponsor:
Project includes demolition of existing asphalt and replacement with a
mix of new asphalt and concrete ends. The fixed wing runway will be
constructed of paved asphalt; two overrun/turnaround/vertical landing pad
areas will be constructed of Portland Cement Concrete (PCC) at each runway
end to accommodate vertical take-off and landing operations of the MV-22.
An asphalt taxiway will also be repaved in the same location to connect
the new runway to the existing apron.
The current runway dimensions are 4,479'x251'; the new runway dimensions
will be 4600'x125', thus reducing the overall paved runway area. The
project also includes chain link security fencing, storm drainage
improvements to existing infrastructure, and clear-zone tree clearing of
-140 AC (see attached map) .
3. This decision memorandum (DM) documents the proper level of
environmental review (CATEX) for this project but may not constitute

authority to proceed with implementation of the project. Please carefully
review and follow the conditions of this DM listed in Enclosure 3.
4. If the project changes, coordinate with the NEPA Program Manager
(451-4542) to determine if this DM continues to cover your proposed
action.

Descriptive Information
Purpose and Need of Action: The existing asphalt runway has exceeded its
useful life and can no longer accommodate either fixed or rotary wing
landings due to Foreign Object Debris (FOD) danger. Without proper
repairs/modernization, aircraft operations/training will continue to be
compromised.

replacement with a mix of new asphalt and concrete ends. The fixed wing
runway will be constructed of paved asphalt; two
overrun/turnaround/vertical landing pad areas will be constructed of
Portland Cement Concrete (PCC) at each runway end to accommodate

Enclosure 3: Appplicable Conditions
AST/UST/IR (Soil) :
1. If contaminants are suspected through odors or visual observation
during construction activities, immediately stop work, call 911, and
contact EQB at 451-9641 for further instructions.
2. There are no known monitoring wells in the project areas but if an
unmarked well is discovered and inadvertently damaged, immediately contact
EQB at 451-9641 for further instructions.
3. The former Camp Davis landfill is located in the wooded area proposed
for tree clearance (south of the road) . Any solid waste removed from the
landfill will need to be properly disposed in accordance with current
state and federal regulations. Please note that the base does not have
any environmental sampling data associated with the landfill, as it was
closed before regulations were established, so it's possible unknown
contamination is present within this landfill.
Interviews and historic documentation indicated the likely presence of
PFAS chemicals associated with former use of AFFF foam in/around the Camp
Davis South runway. There is current Navy guidance requiring treatment of
and/or off-base disposal of any groundwater contaminated with PFOS/PFOA at
concentrations greater than 70parts per trillion (ppt) . Any dewatering
activities for this project should consider the cost implications of
managing PFAS-contaminated water. Sampling should be conducted before any
dewatering activities occur to verify presence/absence and concentrations
of PFAS chemicals. In addition, there is a chance that soil near the
runway has also been contaminated with PFAS. There are currently no
regulations regarding management of PFAS-contaminated soil. However, it's
possible new guidance and regulations may be established prior to start of
construction. As such, it is recommended that a plan be in place to
maintain all soil cuttings on site in close proximity to their original
source area (ie, don't move excess cut off site to another part of the
base) . For additional information, contact the IR Program Manager at
910-451-9385 (Lejeune IR [e-mail]) .

Water Quality Program/ECB:
1. Ensure sediment does not leave a construction site of any size as a
result of land-disturbing activities. Coordinate with Water Quality
Manager, EQB at 451-9518 and the Storm Water Manager, ECB at 451-9522.
2. This project involves the disturbance of over 5,000 square feet.
Therefore, Requirements under Section 438 of the Energy Independence and
Security Act (EISA) will be enforced. The policy, directs all DoD
construction projects and redevelopment projects with footprints greater
than 5, 000 square feet to implement Low Impact Development (LID)
techniques to maintain predevelopment hydrology to the maximum extent
technically feasible. Coordinate with Water Quality Manager, EQB at
451-9518 or Public Works Division, Operations Branch at 451-0869.
3. This project involves the disturbance of 1 or more acres of land and
will require a State approved sedimentation/erosion control plan and
stormwater permit. For questions regarding stormwater requirements
coordinate with Water Quality Manager, EQB at 451-9518. To coordinate the
permit application contact Public Works Division, Design Branch at
451-2213.
4. This project involves addition/construction of 10,000 sqft of
impervious surface area. It requires State permitting through the NCDEMLR
and the design/construction of approved BMPs (Coastal County Rules) .
Coordinate with Water Quality Manager, EQB at 451-9518 and the Storm Water
Manager, ECB at 451-9657.
5. This project falls under an existing state issued stormwater permit
which may need to be modified. Coordinate with Public Works Design Branch
at 451-2213.
6. If additional new built-upon area (BUA) above and beyond the existing
amount is proposed, then at a minimum, a high density BMP is required to
treat that runoff from the new BUA. If the existing BUA within that
drainage area and its runoff cannot be regraded or rerouted, then the
proposed BMP must be designed to accommodate all the runoff within its
drainage area. A full stormwater permit application will be required.
Coordinate with Water Quality Manager, EQB at 451-9518 or Public Works

Division, Operations Branch at 451-0896. Coordinate with Public Works
Design Branch at 451-2213.
7. All construction must be at least 200 feet from any existing or
proposed drinking water supply wells.
Air Quality:
1. Ensure that any fugitive dust emissions generated by
construction/renovation/demolition are appropriately controlled.
AQ program contacts:
Robert Lowder, 451-9607
Wetlands:
1. There are delineated, jurisdictional wetland features within the
construction area. Project should be designed to avoid impact to wetlands
in most recent delineation (expires 11 Dec 2019) . No new delineation
required for runway area. All ground disturbance, material staging, and
operating vehicles must be avoided in wetlands.
2. No wetlands delineation is required if forest clearing adheres to the
attached "Best Management Practices Vegetation Cutting in Wetlands". This
includes the use of matting or rubber-tired vehicles, no significant soil
disturbance (ie. bulldozing of debris or plowing) , and no placement of
materials that effects drainage patterns or fills wetlands.
3. Please contact the wetland SME with any questions at 451-4542.
Note 1: In accordance with BO 11013.4E, projects that include
construction will require site approval from G-F. Please contact
Installation Development Division (IDD) .
