The project includes the disposition of FAA equipment and the demolition of the existing facility.

2.8.2.19 Fuel Piping

The memorandum titled "ATO Fuel Storage Tank, Piping Identification," dated October 3, 2019, requires all visible/exposed piping carrying flammable or combustible fluid to be painted yellow and marked in accordance with ANSI/ ASME A13-1.

2.8.2.20 Funding

Funding for this project is being provided by the Infrastructure Investment and Jobs Act (IIJA)/Bipartisan Infrastructure Law (BIL).

2.8.2.21 Integrated Logistic Support Plan

An Integrated Logistic Support Plan (ILSP) is required to provide a disciplined, unified, and iterative approach to the management and support of National Airspace System (NAS) operational requirements through maintenance planning, supply support, support equipment, technical data, direct work maintenance staffing, maintenance support facilities, computer resources support, training and packaging handling storage and transportation where applicable.

2.8.2.22 Water Supply

Water service (domestic and fire) on the airport is currently supplied via an Airport owned and operated well system. There have been reports at the existing ATCT that this system is somewhat unreliable, and the service is not potable. As a result bottled water is supplied to the facility on a reoccurring basis for applicable domestic purposes.

The design team should therefore explore the available alternatives and perform a cost and reliability feasibility study. Alternatives shall include but may not be limited to;

1. Utilize the existing airport well system with supplemental on-site storage for fire protection along with a facility water treatment system as required based on an analysis of the existing airport water supply.

2. Extend public water from the closest available source

3. Installation of an FAA on-site well(s) system serving the new facility.

4. Any water system servicing the facility, supplemental or whole, shall be connected to emergency electrical service (essential bus/EG).

2.8.2.23 Electrical Service

Extension of 3-phase electrical service to the site will be required for supply to the standard FAA 3-phase Radial system.

2.8.23.24 Sanitary Sewage

There is no public sanitary sewer currently available at the site. The design team should perform a study to determine whether it is cost feasible to extend public service to the site or whether an on-site facility treatment system should be used. If the analysis yields an on-site treatment system, all electrical components of such system must be connected to the emergency power (E/G) and the entire system must comply with local building code requirements.
