(3) Applicable Conditions

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:

Repair or replace storm water drainage measures situated between the back of the Main-Side Commissary 1230 Area and Storm Water Pond-13. The area has several sink holes along existing RCP, as well as an undermined/failing drop inlet. The RCP appears to be failing or fracturing in multiple locations causing the sinkholes.

At the south RCP outlet, storm water runoff is backed up causing flooding into the Parking lot, as well as South eastward towards Holcomb Boulevard due to overgrown grass lined ditch/swale, and efforts to repair through corrective maintenance, IDIQ’s, etc., are not sustainable.

3. Pursuant to subparagraph (33) of reference (c), the proposed action qualifies for the following categorical exclusion: " (33) New construction that is similar to or compatible with existing land use (i.e., site and scale of construction are consistent with those of existing adjacent or nearby facilities) and, when completed, the use or operation of which complies with existing regulatory requirements (e.g., a building within a cantonment area with associated discharges and runoff within existing handling capacities). The test for whether this CATEX can be applied should focus on whether the proposed action generally fits within the designated land use of the proposed site.."

04 Dec 2024

The proposed action will not result in any extraordinary circumstances.

4. In accordance with NEPA, this Decision Memorandum (DM)documents the proper level of environmental review for the proposed action to date but may not constitute authority to proceed with the implementation of the project. Please see the enclosures for more information. If the proposed action changes or does not begin within one calendar year after the date of this DM, please coordinate with the Environmental Planning Program Manager at (910-451-4542) to determine whether this DM 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.

Descriptive Information

Purpose and Need of Action: Design and initiate a project to repair / replace failed or otherwise, failing storm water drainage measures situated between the back of the Main- Side Commissary 1230 Area and Storm Water Pond-13. This will restore the positive flow of storm water flow, alleviate sinkholes, improve drop inlets, recover grass lined ditches and stop flooding.

Scope of Project (Project Narrative): Repair or replace storm water drainage measures situated between the back of the Main-Side Commissary 1230 Area and Storm Water Pond-13. The area has several sink holes along existing RCP, as well as an undermined/failing drop inlet. The RCP appears to be failing or fracturing in multiple locations causing the sinkholes. At the south RCP outlet, storm water runoff is backed up causing flooding into the Parking lot, as well as South eastward towards Holcomb Boulevard due to overgrown grass lined ditch/swale, and efforts to repair through corrective maintenance, IDIQ’s, etc., are not sustainable.

Enclosure 3: Applicable Conditions

AST/UST (Land use Restrictions):

1. This site is located within a Land Use Restriction (LUR) for aquifer use, as well as an intermediate POL groundwater plume. Any encountered groundwater within this LUR boundary may need to be containerized and properly disposed of, or sampled prior to dewatering activities. Please coordinate with the UST program prior to construction.

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. This project is within administratively closed range areas. No historic ranges were present to require entry into the Munitions Response Program. No action is required, however 3R training is recommended and can be completed by viewing the videos at the following location.

https://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 in the Aquifer Use Control Boundary associated with IR Site 78, Operable Unit (OU) 1. All work conducted in an identified EPA NPL OU or RCRA SWMU m ust adhere to the provisions detailed in 29 CFR 1910.120 Occupational Safety and Health Standards, Hazardous Materials, Hazardous waste operations and emergency response.

5. If drilling fluids or other substances/compounds/products are injected into the ground surface, Safety Data Sheets must be sent to EQB for review and screening of potential contaminants.

6. An existing POL above ground storage tank is present and should be protected.

7. There is known groundwater contamination (BTEX) in the vicinity of the project area

Enclosure (3)

(30’ bgs) associated with Installation Restoration (IR) Site 78. Any construction activities that involve digging that deep 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. Contact the IR Program for additional details.
