(2) Supporting Documents

(3) Applicable Conditions

1. In response to enclosure (1), this Decision Memorandum (DM) satisfies the referenced National Environmental Policy Act (NEPA) requirements applicable to the proposed action. Pursuant to the planning considerations for the Department of the Navy (DON) within Appendix A of the reference, this DM also documents the decision to categorically exclude (CATEX) the proposed action from the requirements of preparing an Environmental Assessment or an Environmental Impact Statement.

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

Repair broken water line under Ash Street between building 1005 and 1106. Project will start at the vale on the 1005 side of Ash Street. Project will excavate across Ash Street to water valve located on the 1106 side of Ash Street. Repair exciting water line with new water line. Backfill, compact, grade and sod and repair asphalt.

3. Pursuant to the references, the proposed action qualifies for the following CATEX: "III 35 Acquisition, installation, modernization, repair, or operation of utility (including, but not limited to, water, sewer, and electrical) and communication systems (including, but not limited to, data processing cable and similar electronic equipment) that use existing rights of way, easements, distribution systems, and facilities.." The proposed action will not result in any extraordinary circumstances that may preclude the use of a CATEX.

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.

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. There are no known monitoring wells in the project areas but 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 (Thomas 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

Water Quality Program:

1. Reduction of Lead in Drinking Water Act: Installation or repair of any piping, fittings, fixtures, solder or flux providing water for possible human consumption must be “lead-free” as defined by the Reduction of Lead in Drinking Water Act (RLDWA). The RLDWA revised the definition of lead free to a weighted average of 0.25% of the wetted surfaces of plumbing products and 0.2% lead for solder and flux. A methodology for calculating the weighted average of wetted surfaces can be found at www.epa.gov.
