1. In response to enclosure (1), this Decision Memorandum satisfies reference (a) National Environmental Policy Act (NEPA) requirements applicable to the proposed action.

Pursuant to reference (b) planning considerations, this Decision Memorandum (DM) also documents the decision to categorically exclude (CATEX) the proposed action from the requirements of preparing an Environmental Assessment (EA) or an Environmental Impact Statement (EIS).

2. As outlined in enclosures (1) and (2), the proposed scope of the project is:

Remove damaged areas of concrete and any required substrate, replace with new concrete to required depth and compaction/ density as required. Install moisture barrier under all concrete repairs (if applicable). Replace all expansion trays and seals in the project areas on the runway. Repaint all lines disturbed by project. Replace catch basin beside Military Aircraft Tarmac 7 (MAT) at edge of Combat Aircraft Loading Area (CALA) and clear debris in catch basin downstream. Repair any navigation lights that are disturbed in project area.

3. Pursuant to subparagraph (8) of reference (c), the proposed action qualifies for the following categorical exclusion: " (8) Routine repair and maintenance of buildings, facilities, vessels, aircraft, ranges, and equipment associated with existing operations and activities. (e.g., localized pest management activities, minor erosion control measures, painting, refitting, general building/structural repair, landscaping, or grounds maintenance)." The proposed action will not result in any extraordinary circumstances.

4. In accordance with NEPA, this Decision Memorandum documents the proper level of environmental review for the proposed action to date but may not constitute authority to proceed with implementation of the project. Please see the enclosures for more

05 Sep 2023 information. If the proposed action changes or does not begin within one calendar year after the date of this Decision Memorandum, please coordinate with the Environmental Planning Program Manager at (910-451- 4542) to determine whether this Decision Memorandum continues to apply to the proposed action or whether an updated environmental impact review will be required to find that a CATEX still applies to the proposed action.

Enclosure 3: Applicable Conditions

AST/UST (Land use Restrictions):

1. This site is located within a Land Use Restriction (LUR) for groundwater. Any encountered groundwater within this LUR boundary must be containerized and properly disposed of, or sampled prior to dewatering activities.

Contact:

IR Program, 910-451-9641/9610 AST/UST Program,910-451-5878

AST/UST/IR/MRP (Soil):

1. If contaminants are suspected through odors or visual observation during construction activities, immediately stop work, call 911, and contact EQB at 910-451-9641 for further instructions.

2. Existing monitoring wells are present in this area and should be protected. If they are damaged or will need to be demolished, the wells should be properly abandoned in accordance with State regulations (NCAC 15A 2C) by a State-licensed well driller.

Replacement wells will need to be installed in accordance with State regulations (NCAC 15A 2C) by a State-licensed well driller. If an unmarked well is discovered and inadvertently damaged, immediately contact EQB at 910-451-9641 for further instructions.

3. 3R UXO Safety Awareness Training is recommended for all construction workers as a precaution given that Camp Lejeune has been an active military base since the 1940s. 3R Safety Awareness Training is available online at the following link:

http://www.lejeune.marines.mil/Offices-Staff/Environmental-Mgmt/Training-Video/. Should a munitions-related item be found during construction, follow appropriate notifications as detailed in the 3R training. Any munitions related item found during project construction should additionally be reported to EMD within 10 days (T.Richard, 910-451-9641) to determine if additional evaluation and precautions are necessary (Explosives Safety Submission, UXO Tech Support, etc). Additional UXO safety resources available at: Construction - DENIX (osd.mil) https://www.denix.osd.mil/uxo/for-work-crews/construction/index.html

4. This project is partially within the Aquifer Use Control Boundary associated with IR sites 86 and 54, Operable Units (OU) 15 and 6, as well as active UST Rapid Refueler remediation site and UST site AS845 Notice of Residual Petroleum. All work conducted in an identified EPA NPL OU or RCRA SWMU must adhere to the provisions detailed in 29 CF R

1910.120 Occupational Safety and Health Standards, Hazardous Materials, Hazardous waste operations and emergency response.

***5. There is known shallow groundwater contamination (volatile organic compounds) in the vicinity of the project area associated with Installation Restoration (IR) Site 86.

Any construction activities that require digging into the groundwater will require additional safety precautions (such as 40 hour HAZWOPER training) and waste management for groundwater and saturated soils in accordance with the most current Waste Management Plan.

Enclosure (3)

***6. The project site is impacted by PFAS (per- and polyfluoroalkyl substances) in groundwater. The contractor is responsible for worker safety and education for working within areas impacted by PFAS and eliminating migration/spread of PFAS from leaving the site to the greatest extent practicable. Due to potential AFFF usage in the Airfield vicinity, all concrete must be reused on-site or disposed of at a RCRA D landfill. It is recommended that soil be left in place or at a minimum on site. Any soils removed from the site must be tested and manifested to a permitted Subtitle C or D landfill. Any dewatering activities should either assume PFAS impacts and associated proper containment and disposal, or testing to confirm presence/absence of PFAS above screening criteria. Groundwater extracted below 70ppt PFOA/PFOS combined or separate per DON 201 7, and 2020 update, Interim PFAS Guidance does not require special handling, treatment or disposal.?Groundwater extracted above the DON Guidance policy level of 70ppt PFOA/PFOS must be handled, treated and disposed per DON policy. Equipment, such as borings augers or sheet piling that comes in contact with potentially contaminated soil and groundwater should be decontaminated to prevent the spread of contamination offsite. See EMD's PFAS construction guidance for more information.

***7. There is known soil contamination (petroleum) in the vicinity of the project area associated with Installation Restoration (IR) Site 54. Any construction activities will require additional safety precautions (such as 40 hour HAZWOPER training) and waste management for soils in accordance with the most current Waste Management Plan. In addition, notification to the State and U.S. EPA is required a minimum 60 days prior to start of construction to ensure compliance with existing land use restrictions. The notification shall be done by the Installation's Environmental Management Division and coordinated via the construction contractor.
