ADDITIONAL REQUIREMENTS or COMMENTS Comment 1 The proposed action is within the scope of CATEX #8: Routine repair and maintenance of buildings, facilities, vessels, aircraft, ranges, and equipment associated with existing operations and activities. None of the exclusions from reliance on a CATEX applies in this case; therefore, the proposed action does not require further NEPA analysis.

The applicability of this CATEX determination is based on the full implementation of all environmental requirements identified below.

Requir 1 If excavation is required, work shall be executed in full compliance with the provisions of the General Permit for the Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems (MS4 Permit), the SUBASENLON Stormwater Pollution Prevention Plan, and the SUBASENLON Stormwater Management Plan. Appropriate erosion and sediment control measures shall be used when performing work under the scope of this project.

Requir 2 PW NLON EV Division shall be notified immediately of any actions that require wastewater discharges under the scope of this project. No discharges shall occur without prior approval from with the PW NLON EV Division Wastewater Program Manager (x5159).

Requir 3 PW NLON EV Division Hazardous Waste Program Office (x4298) shall be notified prior to project start regarding any lead removal, recycling, and/or disposal.

Requir 4 If excavation is required, a dig permit shall be obtained from and approved by the PWD prior to initiation of any ground-disturbing activities. Soil management procedures as detailed in the dig permit and the SUBASE Soil Management SOP shall be followed. Soil that cannot be returned to its original location may need to be disposed of off-base at the contractor's expense.

Requir 5 No emissions of asbestos shall be generated in the execution of this project. Full compliance with the provisions of the federal Asbestos NESHAP is required, including proper management and disposal of all asbestos waste generated as a result of performing the prescribed work under this project.

Requir 6 Existing HAZMAT surveys shall be reviewed prior to any disturbance. If suspect hazardous materials (such as asbestos and lead paint) are present and are anticipated to be disturbed under the scope of the project, surveys shall be conducted by qualified individuals in advance of construction activity. All survey results shall be provided to the PW NLON EV Division.

Requir 7 Management, storage, and disposal of any regulated waste shall be coordinated in advance with the PW NLON EV Division Hazardous Waste Program Office (x4298).

- All regulated waste shall be manifested through the Hazardous Waste Program Office.

- Any regulated waste generated under the scope of this project shall be managed, stored, and disposed of in accordance with the SUBASENLON Hazardous Waste Management Plan and SUBASENLON policies and instructions.

- Non-regulated solid waste (i.e., general trash, construction debris, and recyclable items) shall be properly managed and disposed of in accordance with Federal, State, Navy, and local regulations.

Requir 8 Use of exterior storage and laydown areas in support of this project shall be done in compliance with SUBASENLON instructions and policies. Site must be evident of good housekeeping practices consistent with proper storm water management and control.
